A collection box is slidably engaged on the other side of the bottom of the sliding part, and a handle is fixedly installed on one side of the collection box. Although this device can recover powder from various spraying materials, its structure is too complex, difficult to manufacture, and costly. Summary of the Invention

[0004] This invention provides a plasma-sprayed alloy target powder recovery system, which aims to solve the problems of existing plasma-sprayed alloy target powder recovery systems being too complex in structure, difficult to manufacture, and costly.

[0005] This invention provides a plasma-sprayed alloy target powder recovery system, comprising a recovery box and a stripping unit. A support A is fixedly connected to the upper end of the recovery box, a tank body is fixedly connected to the right end of support A, a support B is fixedly connected to the right end of the tank body, and a vacuum pump is fixedly connected to the other side of support B. A support base is fixedly connected to the lower end of the tank body. A rotating platform is screwed into the tank body. An inlet channel and an outlet channel are respectively installed on both sides of the rotating platform. Both the inlet and outlet channels are screwed into the tank body. The other side of the inlet channel is screwed into the recovery box, and the outlet channel... The other side of the tube is screwed to one side of the vacuum pump. A pair of through-holes are pre-drilled on the tank body for the stripping unit to pass through. A guide groove is installed at one of the through-holes on the upper side of the tank body. The angle between the pair of through-holes and the center of the tank body is one-third of the circumference. Three concave openings are pre-drilled on the rotating platform, with the angle between adjacent concave openings being one-third of the circumference. The stripping unit includes a guide tube and a stripping tube. One side of the stripping tube is fixedly connected to the guide tube. The stripping tube isolates the space inside the guide tube into a stripping chamber and a venting chamber. Several stripping grooves are opened on the stripping tube. The guide tube has openings on both sides that connect to the stripping chamber and the venting chamber. Fastening units for locking the stripping unit are installed on both sides of the rotating platform opposite the concave orifice. Each fastening unit includes a guide port, and a rubber channel connects the guide port, the inlet channel, and the outlet channel. A traction unit is installed on the support base and the outlet channel to pull the rotating platform to rotate one-third of a revolution. A traction part is installed on the tank body to pull the fastening units on both sides of one concave orifice closer together. Each fastening unit includes a moving rod. Elastic element A, leak-proof ring, elastic element B, and sealing platform are arranged. Assembly platforms are installed on both sides of the rotating platform. The guide opening is a right-angled folded ruler shape and is located in the leak-proof ring. One side of the variable rod passes through the assembly platform and extends into the guide opening. The sealing platform is located in the guide opening and is fixed to the variable rod via a tension screw. Elastic element A is clamped to the outer circumference of the variable rod and drives the sealing platform to press against the guide opening to perform a blocking action. Both sides of elastic element B and the leak-proof ring are in close contact with the variable rod, and elastic element B drives the leak-proof ring to press against the assembly platform.

[0006] Furthermore, connecting seats are installed on both sides of the guide tube, and an assembly port for cooperation with the connecting seat is opened on one side of the leak-proof ring.

[0007] Furthermore, the traction unit includes an arched platform, which is fixed to the inner wall of the tank via a tensioning screw. The arched platform is located on the circumferential trajectory of the rotating rod. The curvature of the arched platform is less than a quarter of a circumference, and the maximum travel of the leak-proof ring is less than the thickness difference between the two sides of the arched platform.

[0008] Furthermore, a bearing rod is installed between the assembly table and the rotating table. The assembly table is fixed to the rotating table via a tension screw, and the axial length of the bearing rod is less than the axial length of the leak-proof ring.

[0009] Furthermore, the traction unit includes a motor fixed to the support base and a sprocket A fixed to the outflow channel, a chain, a sprocket B fixed to the rotating part of the motor, and sprocket B and sprocket A connected by a chain.

[0010] The beneficial effects of this invention are as follows:

[0011] This invention comprises a tank, a rotating platform, a stripping unit, a fastening unit, and a traction unit. The traction unit pulls the rotating platform to rotate, allowing the stripping unit to rotate along with the platform. This enables the stripping unit to be interchanged to recover powder from different coating materials. When the stripping unit rotates to a point where a pair of through-holes deviate, the traction unit pulls a pair of fastening units to lock both sides of the stripping unit. This also allows gas to move through the inlet channel, the stripping unit, and the outlet channel, causing dust to move into the stripping unit and be stripped out. The overall structure is very simple, easy to manufacture, low in cost, and very convenient to use.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] Reference Figures 1-9This invention proposes a plasma-sprayed alloy target powder recovery system, comprising a recovery box 1 and a stripping unit 7. A support A2 is fixedly connected to the upper end of the recovery box 1, a tank 3 is fixedly connected to the right end of the support A2, a support B35 is fixedly connected to the right end of the tank 3, and a vacuum pump 36 is fixedly connected to the other side of the support B35. A support base 5 is fixedly connected to the lower end of the tank 3. A rotating platform 10 is screwed into the tank 3. An inlet channel 4 and an outlet channel 17 are respectively installed on the two sides of the rotating platform 10. Both the inlet channel 4 and the outlet channel 17 are screwed into the tank 3. The other side of the inlet channel 4 is screwed into the recovery box 1, and the other side of the outlet channel 17 is screwed into one side of the vacuum pump 36. A pair of through-holes 8 are reserved on the tank 3 for the stripping unit 7 to pass through. A guide groove 6 is installed at one of the through-holes 8 on the upper side of the tank 3. The angle between the pair of through-holes 8 and the center of the tank 3 is one-third of the circumference. Three concave shapes are reserved on the rotating platform 10. The angle between two adjacent concave openings 9 is one-third of the circumference. The peeling unit 7 includes a guide tube 34 and a peeling tube 32. One side of the peeling tube 32 is fixed to the guide tube 34. The peeling tube 32 isolates the space inside the guide tube 34 into a peeling chamber 29 and a venting chamber 33. Several peeling openings are opened on the peeling tube 32. The guide tube 34 has connection openings 30 on both sides that connect to the peeling chamber 29 and the venting chamber 33. The rotating table 10 is equipped with fastening units 18 on both sides opposite to the concave openings 9 to lock the peeling unit 7. The fastening unit 18 includes a guide opening 24. A rubber channel 25 connects the guide opening 24 to the inlet channel 4 and the outlet channel 17. The bearing seat 5 and the outlet channel 17 are equipped with a traction unit 16, which is used to pull the rotating table 10 to rotate one-third of the circumference. The tank body 3 is equipped with a traction part for pulling the fastening units 18 on both sides of one concave opening 9 to approach each other.

[0026] The fastening unit 18 includes a movable rod 19, an elastic element A20, a leak-proof ring 21, an elastic element B26, and a sealing platform 23. Assembly platforms 14 are mounted on both sides of the rotating platform 10. The guide opening 24 is a right-angled folded ruler shape and is located within the leak-proof ring 21. One side of the movable rod 19 passes through the assembly platform 14 and extends into the guide opening 24. The sealing platform 23 is located within the guide opening 24 and is fixedly connected to the movable rod 19 via a tensioning screw. The elastic element A20 is clamped to the outer circumference of the movable rod 19 and drives the sealing platform 23 to press against the guide opening 24 to perform a blocking action. Both sides of the elastic element B26 and the leak-proof ring 21 are tightly pressed against the movable rod 19, and the elastic element B26 drives the leak-proof ring 21 to press against the assembly platform 14. The traction part includes an arched platform 27, which is fixedly connected to the mounting platform 14 via a tensioning screw. On the inner wall of the tank body 3, and the arched platform 27 is on the circumferential trajectory of the rotating rod 19, the curvature of the arched platform 27 is less than a quarter of a circumference, and the farthest stroke of the leak-proof ring 21 is less than the thickness difference between the two sides of the arched platform 27. When one side of the rotating rod 19 is in contact with the arched platform 27, the rotating rod 19 presses the elastic element A20 and pulls the leak-proof ring 21 to move in the concave opening 9, so that the leak-proof ring 21 approaches the stripping unit 7. When a pair of leak-proof rings 21 lock the stripping unit 7, the leak-proof ring 21 cannot move. At this moment, the rotating rod 19 is then pressed by the arched platform 27 and presses the elastic element B26. In this way, the rotating rod 19 can pull the sealing platform 23 to move, so that the guide port 24 opens, and the gas can successfully flow in the inlet channel 4, the stripping unit 7 and the outlet channel 17.

[0027] Connecting seats 31 are installed on both sides of the guide tube 34. The cross-section of the connecting seat 31 is funnel-shaped. The anti-leak ring 21 has an assembly port 22 that cooperates with the connecting seat 31 on one side. When the moving rod 19 pulls the anti-leak ring 21 toward the guide tube 34, the anti-leak ring 21 can block the connecting seat 31 by means of the cooperation between the connecting seat 31 and the assembly port 22, so that the powder and gas can successfully move from the guide port 24 into the stripping unit 7 or from the stripping unit 7 into the guide port 24.

[0028] A bearing rod 28 is installed between the assembly platform 14 and the rotating platform 10. The assembly platform 14 is fixed to the rotating platform 10 via a tension screw. The axial length of the bearing rod 28 is less than the axial length of the leak-proof ring 21. After the assembly platform 14 and the rotating platform 10 are assembled in the tank body 3, one side of the leak-proof ring 21 is in close contact with the assembly platform 14, and the other side of the leak-proof ring 21 is in the concave opening 9. When the moving rod 19 is pressed by the arched platform 27, it can successfully pull the leak-proof ring 21 to move in the concave opening 9.

[0029] The traction unit 16 includes a motor 15 fixed to the support base 5 and a sprocket A11 fixed to the outflow channel 17, a chain 12, and a sprocket B13 fixed to the rotating part of the motor 15. The sprocket B13 and the sprocket A11 are connected by the chain 12. The motor 15 pulls the sprocket B13 to rotate, and the chain 12 pulls the sprocket A11 and the outflow channel 17 to rotate. Since one side of the outflow channel 17 is fixed to the rotating table 10, the rotating table 10 can pull the stripping unit 7 to rotate together, so that the stripping unit 7 can rotate to various positions, thereby achieving the purpose of stripping dust. By intermittently running the motor 15, the position of the stripping unit 7 can be adjusted, and it can be used to recover powder generated by different spraying materials.

[0030] The specific implementation method is as follows: In use, the recycling box 1 is connected to the dust collection device of the plasma spraying equipment. The clean peeling unit 7 is placed in the guide groove 6. One of the peeling units 7 is moved into the concave opening 9 on the rotating table 10. Then, the motor 15 pulls the rotating table 10 to rotate one-third of a turn, so that the rotating table 10 pulls the fastening unit 18 and the peeling unit 7 to rotate one-third of a turn together. During the rotation of the fastening unit 18, the moving rod 19 presses against the arched platform 27 and moves along the wall of the arched platform 27, so that the moving rod 19 is squeezed and the elastic element A20 is shortened, and the anti-leak ring 21 is pulled and pressed against the peeling unit 7 until a pair of anti-leak rings 21 lock the guide tube 34. The anti-leakage is completed by the cooperation of the connecting seat 31 and the assembly port 22. The moving rod 19 then bears the pressure of the arched platform 27, so that the elastic element B26 is shortened, the sealing platform 23 moves, and the sealing of the guide port 24 is released. The air extractor 36 extracts air. The dust is drawn into the inlet channel 4 and peeled off by the stripping unit 7, then flows away through the outlet channel 17. When the coating material is changed, the motor 15 pulls the rotating table 10 to rotate one-third of a turn. During this period, the arched table 27 releases the pressure on the variable rod 19. The variable rod 19 and the leak-proof ring 21 return to their original positions under the traction of the elastic element A20 and the elastic element B26, allowing the pair of fastening units 18 to release the locking of the stripping unit 7. When the stripping unit 7 rotates to the through port 8 directly opposite the bottom, the stripping unit 7 containing the coating material powder can detach from the through port 8, thereby recovering the powder of different coating materials. At the same time, the stripping unit 7 can be quickly replaced, which is very convenient to use. Then, the dust can be continuously stripped and recovered. In addition, when one of the stripping units 7 is performing dust stripping, the guide ports 24 on the other two fastening units 18 are blocked by the sealing table 23 to ensure that the dust cannot overflow.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
