[0036] The rest is the same as in Example 1.

[0037] Example 3 A device for separating and recovering surface deposits on workpieces with material includes a sealed housing 1, a shot blasting system (shot blasting unit 2), a motion module (motion unit 5), a workpiece loading plate (workpiece loading unit 4), and a shot separation and powder collection system (shot lifting and separation unit 3). The device achieves separation and cleaning of deposits from the workpiece by directional and continuous impact of steel shot or ceramic shot on the workpiece surface. The cleaning process occurs within the sealed housing 1, preventing dust diffusion, and the deposits are collected using cyclone separation and filtration. The shot blasting mechanism utilizes the kinetic energy of a high-speed shot swarm to impact the target surface. Through the coupling of multiple actions such as surface micro-cutting, fatigue failure, brittle fracture, and impact peeling, the surface deposits are directly peeled off, cracks propagate, and pulverizing fracture is induced, causing the deposits to fall from the substrate. The shot blasting system is installed on the side wall of the sealed housing 1. Steel shot or ceramic shot, etc., gain centrifugal force during the high-speed rotation of the shot blasting system and are shot out in a straight line at the outlet to hit the surface of the workpiece. The motion system is installed on the partition 104 inside the sealed housing 1, with the workpiece clamping position facing the outlet of the shot blasting system. The feed port of the shot separation and powder collection system is connected to the bottom of the sealed housing 1, and the shot discharge port is connected to the shot blasting system to realize the feeding of the shot blasting system. The system outlet is connected to the top of the sealed housing to realize the internal circulation of gas and avoid dust pollution during the operation.

[0038] The aforementioned sealed box 1 consists of chamber one 101, chamber two 102, bellows cover 103, and partition 104. The workpiece loading plate is located inside chamber one 101 and is connected to the motion module via connecting shaft 511. The angle of the workpiece mounting plate is adjustable. The motion module is installed inside chamber two 102. Chamber one 101 and chamber two 102 are isolated by the bellows cover. The bottom of chamber one 101 consists of multiple inclined surfaces that converge at a point, facilitating the concentration of materials.

The Y-axis motor 501 is fixed on the partition 104, and the Y-axis lead screw nut 503 is fixedly connected to the Y-axis motion plate 504. The Y-axis motor 501 drives the Y-axis lead screw 502 to rotate, and simultaneously drives the Y-axis lead screw nut 503 to move, thereby enabling the Y-axis motion plate 504 to move up and down along the Y-axis guide rail 505. The x-axis motor 506 is fixed on the y-axis motion plate 504. The x-axis motor 506 drives the x-axis lead screw 507 to rotate, and at the same time drives the x-axis lead screw nut 508 to move, so that the x-axis motion plate 510 can move left and right along the x-axis guide rail 509. The x-axis motion plate 510 is fixedly connected to the connecting shaft 511.

After the control valve 203 is opened, the shot enters the shot blaster 201 through the receiving port 204. The drive motor 202 drives the shot blaster 201 to rotate at high speed, generating centrifugal force on the shot to accelerate its motion, gain kinetic energy, and finally eject it from the outlet to strike the surface of the workpiece.

Pipe 3 306 is inserted into the inlet of the bin cover 3073, and the filter element 3072 is installed at the outlet of the bin cover 3073. A small amount of adhering material enters the material dust collection bin 307 with the airflow from pipe 3 306 and is captured by the filter element 3072. Pipe 4 308 is connected at one end to the outlet of the bin cover 3073 and at the other end to the air intake of the fan 309. Pipe 5 310 is connected at one end to the exhaust port of the fan 309 and at the other end to the sealed box 1 to realize the self-circulation of airflow.

The Y-axis motor 501 is fixed on the partition 104, and the Y-axis lead screw nut 503 is fixedly connected to the Y-axis motion plate 504. The Y-axis motor 501 drives the Y-axis lead screw 502 to rotate, and at the same time drives the Y-axis lead screw nut 503 to move, so that the Y-axis motion plate 504 moves up and down along the Y-axis guide rail 505.

After the control valve 203 is opened, the shot enters the shot blaster 201 through the receiving port 204. The drive motor 202 drives the shot blaster 201 to rotate at high speed, generating centrifugal force on the shot to accelerate its motion, obtain kinetic energy, and finally shoot it out from the outlet to hit the surface of the workpiece.

[0046] The aforementioned pellet lifting and separation unit 3 consists of a pellet cylinder 301, pipe one 302, a primary cyclone separator 303, pipe two 304, a secondary cyclone separator 305, pipe three 306, a material dust collection bin 307, pipe four 308, a blower 309, and pipe five 310.

In the primary cyclone separator 303, the pellets are separated from any attached material, and the pellets gradually fall into the bottom pellet cylinder 301 during rotation. Pipe two 304 is connected at one end to the exhaust port of the primary cyclone separator 303 and at the other end to the inlet of the secondary cyclone separator 305. Attached material enters the secondary cyclone separator 305 along with pipe two 304, and most of the larger particles gradually fall into the secondary cyclone separator 305 during rotation. At the bottom of the secondary cyclone separator 305, the remaining small particles are sucked into the dust collection bin 307 via pipe 306. One end of pipe 306 is connected to the exhaust port of the secondary cyclone separator 305, and the other end is inserted into the dust collection bin 307. The dust collection bin 307 is mainly composed of a cylinder 3071, a lid 3073, and a filter element 3072. Pipe 306 is inserted into the inlet of the lid 3073, and the filter element 3072 is installed at the outlet of the lid 3073. A small amount of the particles are carried by the airflow from pipe 306 into the dust collection bin 307 and captured by the filter element 3072.
