[0005] As a further improvement of the above technical solution:

[0006] The shot blasting cleaning chamber includes a shot blasting chamber, a front auxiliary chamber and a rear auxiliary chamber. The front auxiliary chamber and the rear auxiliary chamber are respectively arranged at the front and rear sides of the shot blasting chamber. A plurality of shot blasting machines are evenly arranged on the outer circumference of the shot blasting chamber.

[0007] A sealing device is provided above the shot blasting cleaning chamber, and a hanging conveying device is provided above the sealing device.

[0008] A platform is provided above the hanging conveying device, and the hanging conveying device is fixedly connected to the platform.

[0010] A storage box is provided below the separator.

[0011] A pill supply valve is provided below the storage box.

[0012] The front auxiliary chamber and the rear auxiliary chamber are respectively provided with dust collecting devices.

[0013] Due to the adoption of the above technical solution, compared with the prior art, the advantages of the present invention are: the shot blasting machine in the shot blasting cleaning chamber can be individually opened and closed or frequency-controlled according to the type of workpiece, and the shot blasting cleaning of steel structure workpieces can be achieved by one machine, with low production cost and high production efficiency; the production line speed can reach 0.5-4m / min, and the production speed is fast.

[0014] During operation, the hanging conveying device lifts the workpiece, and the electronic control system selects to open the corresponding shot blasting machine to start blasting the workpiece.
