[0002] Shot blasting cleaning is a kind of equipment that uses a high-speed rotating impeller to throw abrasive particles onto the surface of the workpiece to achieve the purpose of cleaning the workpiece. This equipment is widely used in various industries for tasks such as sand removal, rust removal, descaling and surface strengthening of castings and forgings. When the existing shot blasting machine cleans the surface of mold steel, the projectiles of the shot blasting machine will bring out the impurity layer and burrs on the surface of the mold steel when they hit the mold steel. The projectiles of the shot blasting machine are usually reused. Therefore, in order to avoid the projectiles carrying steel chips and broken shots brought out by the previous wave of shot blasting, it is necessary to design a cleaning device for mold steel shot blasting machines.

[0006] The collecting guide groove is provided with chamfers at two locations.

[0007] The above structure is adopted to facilitate the collection of projectiles.

[0008] The magnetization device is arranged with the same polarity as the magnetic strip.

[0020] The shots in the present utility model are alloy shots.

[0021] In the present utility model, the magnetization device 8 adopts an existing product that can magnetize alloy projectiles within a short period of time.

[0022] In the present utility model, the magnetic strip 9 is connected to an external electric control structure to form an electromagnet structure.

[0023] A chamfer is provided at the collection guide groove II 10.

[0024] The magnetization device 8 and the magnetic strip 9 are arranged with the same polarity.

[0025] The collection hopper 1 is closer to the blowing fan I 3 in the horizontal direction than the material guiding pipe 5.

[0026] In the present utility model, the corrected offset can be adjusted according to the weight of the projectiles.

[0027] The inner walls of both the cleaning chamber 2 and the air duct 6 are made of alloy materials.

[0029] The working principle of the present utility model: The collection hopper 1 is arranged below the working area of the die steel shot blasting machine. The shot material mixture after shot blasting treatment is collected through the collection hopper 1. The shot material mixture enters the cleaning chamber 2 under the action of gravity. The broken shots and impurities lighter than the projectiles are blown off by the blowing fan I 3 on the side and collected in the collection guide groove I 4. The preliminarily cleaned projectiles then enter the material guiding pipe 5 and are guided to the air duct 6.
