Do you know the characteristics of container shot blasting cleaner?

Container shot blasting cleaner equipment is mainly used to clean up the rust, oxide scale and welding slag on the surface of newly built and repaired container train body and large parts. It can also reduce the internal stress of the workpiece, improve the fatigue strength and strengthen the surface hardness of the workpiece. The quality coverage rate of surface shot blasting treatment reaches 100% for the workpiece treated by this equipment.

The cleanliness of the rust removal surface is up to Sa2.5 grade of GB8923 (surface rust grade and rust removal grade of steel before painting). The surface roughness is Ra3.2-12.5 micron, which improves the adhesion of the paint film and correspondingly improves the corrosion resistance and surface quality of the product. The equipment mechatronics, high degree of automation. The equipment mainly consists of workpiece conveying system, front cleaning room, shot blasting room, back cleaning room, soot blowing and reinforcing spraying system, abrasive circulation system, ventilation and dust removal system, electrical control system, etc.

1. Ground Pit Foundation: Used to install various parts of the equipment, including ground pit, embedded parts, vertical ladder, etc.

2. Chamber body: Made of steel structural parts, when installed, chamber body, bucket elevator base, funnel and its supporting pillars need to be welded with embedded parts around and at the base, all of which are continuous welds.

3. Shot blaster: This equipment uses 19 Q034 shot blasters, which have stable performance, convenient maintenance, long service life and good cleaning effect.

4. Elevator: This equipment adopts flat belt digging bucket elevator. The lower part is connected with the outlet of the transverse screw conveyor, the upper part is connected with the separator, and the suction outlet in the room is connected with the shell of the elevator. Therefore, the elevator is used as a ventilation tube and has good dust removal effect.

5. Screw conveyor: This equipment adopts three vertical screw conveyors and one transverse screw conveyor to carry out pellet conveying.

6. Separator: The balance hammer type gravity automatic control air separator is used. The mixture of pellet and sand is poured into the separator by the hoist, which produces pressure on the separator plate and forms a moment at the edge of the cutter. When the moment is balanced with the moment formed by the balance hammer, the pellet and sand completely cover the separator plate and form a full curtain. The pellet-sand mixture from the separating plate falls under the condition of full curtain and is blown by 5-7 m/s airflow. The sand enters the sand storage bucket. The pellet falls directly into the pellet storage bucket for recycling. The dust passes through the air passage plate and through the hoist to the dust removal system.

7. Projectile Distribution System: There are 19 steel shot distributor pipes leading to 19 shot blasters. Pneumatic sector valves are installed at the end of each distribution pipe, which are controlled by electrical system and can supply shot to each shot blaster separately, and the quantity of shot is adjustable.

8. Air control system: The door of the room body and the fan-shaped valves are all pneumatic, and the solenoid valves are centrally installed in the valve box.

9. Dust removal system: Dust-laden airflow enters through the top air inlet, fills the gap between the filter bags in the filter chamber downward, large particles of dust sink into the hopper with the downward air flow, small particles of dust are blocked by the filter bags, purified air passes through the bag wall through the ceiling hole to collect the cleaning chamber, flows from the lower part into the rotary switching passage, and finally is discharged by the main fan through the exhaust port. Complete the filtering condition. When the upper limit of control is reached, the rotary switching impulse ash removal mechanism is activated, and the air stopping and positioning of each chamber is sprayed in turn until the resistance of the filter bag drops to the lower limit of control, and the dust removal mechanism stops working.
