Wind power sand blasting room

Details

Dongguan Meijun sand blasting equipment environmental protection wind power sand blasting room, large wind dust extraction device, sand back and sand extraction smooth and low failure

Working principle of honeycomb dust and sand separation blasting room:

Sand blasting room is mainly divided into sand blasting system, sand material recovery, separation, dust removal system, and room dust removal system.

Precautions:

Use honeycomb floor to return sand automatically;

1) It is required that the sand blasting machine must be linked with the lower sand hopper.The sand blasting machine needs to have the ability to automatically control the sand addition, such as the linkage system, the material level instrument induction system, etc .; (the machine model is different, compared with the manual sand blasting machine requirements (Increased, cost changes)

2) Add abrasive lifting system;

3) Add abrasive dust separation, screening and storage systems.

1: sand hopper at the bottom of the blasting room

The sand collecting bucket at the bottom adopts the module splicing mode, and the unit collecting bucket is welded by steel plate and channel steel as a whole, and then spliced according to the required area (fixed and removable). The sand in the unit is conveyed by the screw, and the abrasive is collected to the side of the sand collection. Bucket, and then use a mechanical bucket to lift to the cyclone sand separator at the bottom of the blasting tank for sand and dust separation, and then the abrasive falls into the sand collecting bucket, and automatically adds sand according to the blasting start and stop status. Dust and small unusable abrasive waste The particles enter the dust collector through the suction pipe, and the free fall falls into the dust collecting bucket at the bottom of the dust collector.

Tips: According to the customer's easy use of the money-saving mode, the customer digs a square trench tank, a steel plate sand hopper, the bottom is longitudinal, and two sets of screw conveyor slots are placed horizontally, and a 5 * 8 meter honeycomb grid floor is laid.

2 sets of screw conveyors ( horizontal and vertical ) + 2 motors + full steel plate sand collecting bucket

2: grille floor

The floor of the blasting room uses a metal grille, which facilitates the collection and removal of steel sand on the one hand, and the other side

It is good for workers to walk safely. In order to prevent large volumes of impurities and foreign objects from entering the sand return pipe through the honeycomb during working hours, and blocking the spray gun, this equipment sets a filter at the lower part of the grille (honeycomb floor) to prevent the impurities and foreign objects from entering. The cleaning of impurities and foreign matter is very convenient. Just open the grille laid on the ground inside the house, and it can be completely cleaned, so that the recycling pipe network can work smoothly and for a long time.

The floor grid is welded with 40 * 4mm flat steel bars or using prefabricated grid floor. specific

The size and quantity are determined by the size of the house and the track spacing of the work trolley. Generally, the floor grille inside the sand blasting room has a load per square meter of less than 200kg. If a larger floor grille is required, the customer needs to put forward special design requirements.

5 * 8 meter grid floor + channel steel beam frame (time- consuming and labor-intensive )

Three: sand material recovery system

1) Sand collecting bucket

The bottom of the blasting room is the area for collecting sand and arranging the suction pipe, which is specially used to collect sand blasting

Loose abrasive and dust generated during blasting. In this solution, the steel plate in the sand collection area is made into a sealed inverted "V" shape, which is conducive to the recovery and capture of abrasives and dust. The sand blasting room sand hopper module combination can be separated.

The honeycomb sand return system fully considers the wear and maintenance of the honeycomb recycled floor and the recycling pipeline during long-term use. The recycled floor and the recycling pipeline are made into a detachable modular combination method, which makes the maintenance of the equipment extremely simple and quick, and saves A large number of replacement parts reduce the maintenance cost of the equipment during long-term use. The blasting room of this type of structure only needs to make the trench depth to 1 meter (the trench depth is selected according to the number of integrated buckets, the smaller the number, the higher the excavation depth).

喷砂房,打砂房

The bottom of the honeycomb floor is evenly covered with small honeycomb buckets. These small buckets are connected to the pipeline conveying trough under the bucket. The pipes are conveyed by reverse screws. The two ends of the unit sand bucket are driven to the middle. At that time, all the discharged sand fell into the small honeycomb bucket, and then fell from the small bucket into the pipe conveying trough, and finally fell into the horizontal main conveying trough in the middle of the sand collecting trough at the bottom. The bottom of the elevator is lifted into the sand and dust separator by the bucket inside the elevator. After the sand and dust are separated, it falls into the storage hopper at the bottom of the separator and waits for the sand lower valve to open and fall into the sand blaster tank.

The honeycomb recycling floor has a relatively quick and easy way of maintenance.

First of all, the honeycomb floor has a simple structure, there are few easy-wear parts, and there are few parts that need maintenance. Moreover, the honeycomb floor adopts a block combination method, which can easily disassemble each part and enter the maintenance point. Then the honeycomb floor is made into "standard parts", such as bent pipes that are easy to wear, that is, made into standard replacement parts, connected by flange interface. When replacing, just open the bucket plate, loosen the interface, take out the worn parts and replace them with new parts. No need to weld and cut on site. Greatly facilitate daily maintenance.

2) Mechanical bucket elevator

Specifications: height 4200MM (determined according to the height of the sand tank)

Lifting body size: 600 * 220MM

Lifting motor: 1.1-2.2 kW (determined according to the type of abrasive and the height of the sand tank)

Four: sand and dust separation system

In order to ensure the quality and efficiency of sand blasting, it is necessary to effectively recover the mixture of sand and dust recovered from the honeycomb floor.

After the sand and dust are separated, the sand can continue to be recycled. The main function of the sand and dust separator is to separate sand and dust efficiently and accurately.

The quality of the separation directly affects the blasting performance of the blasting machine and the filtering performance of the dust collector.

What needs to be used here is a sand dust separator:

1) Cyclone sand dust separator + dust collector (7.5HP)

This sand and dust separator adopts the Japanese series separator specially designed by our company for the sand blasting system. It uses air separation to separate abrasives with different particle sizes.

It can effectively separate the sand and dust in the recovery system. The separated complete sand is returned to the main body of the sand blasting machine and continued to be used. The dust and crushed sand are sent to the dust collector, filtered and stored in the dust storage tank to wait. Clean up regularly.

The function of the cyclone inertial separator is to make the dust-containing gas rotate and use the effect of centrifugal force to capture the fine particles of dust from the airflow. This air-selected separator has a simple structure, stable performance, no moving parts, and easy maintenance and management. Is a widely used primary dust removal equipment, dust removal efficiency is generally about 90%. The separator configured by this equipment adopts the latest structure and is accurately designed.

The lower end of the separation unit is provided with a sand collector (storage box), and the outside of the unit is provided with a maintenance and protection frame. The volute unit on the separation unit is connected with the filter (filter element) dust collector, which is beneficial to reduce noise and improve the quality of the working environment. By adjusting the adjustment mechanism on the sand and dust separator, the diameter of the separation sand material can be adjusted, which is suitable for brown steel jade. , Steel shot, steel sand and other sand and dust separation occasions, the applicability is very strong.

During the work of the sand separator, the high-speed impacted parts of the sand are wearing parts. Our company fully considered this problem in the design process and made reliable protection treatment inside the pipeline.

The protective plate is made of high abrasion resistant material. During use, the protective plate can be inspected regularly. When the protective plate is worn out, it should be replaced in time to avoid grinding through the wall of the dust separator and then repairing it. In this way, the original appearance of the device will not be damaged, and a lot of maintenance and repair time can be saved.

Separating abrasive types: steel grit / corundum.

2) Maintenance platform and sand bucket protection frame

The lower end of the separation unit is provided with a sand collector (sand storage bucket). The sand storage bucket needs frequent maintenance to observe and prevent clogging. Therefore, there is a maintenance and protection frame on the outside of the unit. The landing platform is provided with a fence to prevent personnel from accidentally falling.


Five: storage hopper system

The storage hopper is one of the important components of room equipment.

All the sand passes through the sand-dust separator

After separation, short storage in the storage hopper is required.

When the sand material in the sand blasting machine is used up, the storage hopper automatically replenishes the sand material into the sand blasting machine.

Six: Dust removal system 2 10HP dust collector

The dust removal system consists of suction and dust exhaust ducts, bottom and side dust suction ports, modular filter cartridge dust collectors, dust exhaust fans, dust exhaust chimneys and other components.

The working principle of the dust removal system:

installation 回收式喷砂房 The sand blasting room of the honeycomb floor sand returning system is adopted. The blasting room dust removal system can adopt the cyclic dust suction treatment method of upper inlet air, lower and side exhaust air (see the working principle diagram of the room body).

Clean air enters the sand blasting room from the top of the room, and the dust removal fan sucks the polluted and turbid gas in the room into the dust collector through various suction ports for collection and treatment. Since the dust recovery inlets of the environmentally-friendly air-recycling sand blasting room are all arranged under the honeycomb sand absorbing floor and on the side wall of the room, the dust is always moved from top to bottom by the air flow, and the dust has been suppressed in the sand blast The lower part of the room, so the dust concentration in the sand blasting room above 0.5 meters is very low, the visibility is very high, and the working environment is good.

The sand recovery fan collects sand and dust from the honeycomb floor and enters the sand separator for sand separation and separation. At the same time, it also sucks a part of the unused dust into the filter to remove and collect the dust, and the clean air is discharged out of the atmosphere. The dust exhaust pipes of the two dust exhaust fans can be combined as required, and finally enter the exhaust chimney to achieve the standard emission standards.
