Description

Technical Field

[0001] The invention belongs to the technical field of powder recovery, and in particular relates to a powder recovery device for vertical powder spraying equipment. Background Art

[0002] Electrostatic powder spraying has been widely used in the spraying processing of metal parts in different industries. It has the advantages of controllable spraying, uniform coating, high spraying efficiency, etc. Powder spraying also has spraying effects such as high mechanical strength, good adhesion, corrosion resistance, and aging resistance. At present, for batch spraying operations or assembly line spraying operations, a special spray powder room is often set up. The workpieces to be sprayed enter the spray powder room through a hanging conveyor system for spraying. After the spraying is completed, it is transported to other processing stations. The spray powder room can improve the effect of the workpiece spraying on the one hand, and it can also help to recycle and reuse the powder coating, reduce costs and prevent environmental pollution.

[0003] When the workpiece is sprayed in the spray powder room, the excess powder will remain inside the spray room and be sucked into the powder recovery device through the ventilation duct installed on the spray room for filtration, separation and storage for subsequent recycling, which can reduce the waste of powder, save costs, reduce environmental pollution and improve production efficiency;

[0004] When the powder recovery device is in use, the filter element needs to be disassembled and cleaned or replaced to ensure that the recovery effect of the powder recovery device is not affected. However, most of the existing filter elements are fixed to the powder recovery device by bolts, etc., which is troublesome and inefficient to disassemble and assemble the filter element. In addition, a large amount of dust will be adsorbed on the surface of the filter element. When the filter element is disassembled and assembled, the dust on the surface of the filter element will float in the working environment, polluting the working environment. The staff are also prone to inhaling powder, which will damage the respiratory tract of the staff and affect the health of the staff.

[0005] Therefore, we propose a powder recovery device for vertical powder spraying equipment to solve the above problems. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example

[0033] See also Figure 1 - Fig. 9As shown, a powder recovery device for a vertical powder spraying equipment includes a box body 1, a dust inlet pipe 2 is arranged at the lower right end of the box body 1, a filter element 3 is arranged inside the box body 1, an annular mounting plate 4 is arranged at the upper end of the filter element 3, an L-shaped limit block 15 is arranged on the lower surface of the annular mounting plate 4, and the L-shaped limit block 15 is provided with four pieces, all of which are inserted into the upper end of the box body 1, and the lower end side wall of the L-shaped limit block 15 is provided with a tooth plate 16, and the side wall of the tooth plate 16 is meshed and connected with a spur gear 18 The spur gear 18 is rotatably mounted inside the box body 1 through the rotating rod 17. The upper end of the rotating rod 17 passes through the box body 1 and is provided with a stopper 20. The circumferential surface of the upper part of the rotating rod 17 is provided with a rotating abutment block 21, and the bottom of one end of the rotating abutment block 21 abuts against the upper surface of the annular mounting plate 4. The upper surface of the rotating abutment block 21 is provided with a spring 21, and the upper end of the spring 21 is connected to the stopper 20. The setting of the stopper 20 can limit the upper end of the rotating rod 17 so that the spring 21 can be rotated. The spring 21 and the rotating abutment block 21 can be stably installed on the rotating rod 17 without affecting the vertical movement of the rotating abutment block 21, wherein the interior of the rotating abutment block 21 is slidably connected to the rotating rod 17 through a slider, so that when the rotating rod 17 rotates, it can drive the rotating abutment block 21 to rotate horizontally, and at the same time does not affect the vertical movement of the rotating abutment block 21 on the rotating rod 17. A spring 3 22 is arranged inside the rotating abutment block 21, and a circular limiting block 23 is arranged at the lower end of the spring 3 22. A circular limiting groove 24 is opened on the upper surface of the annular mounting plate 4, and the lower end of the circular limiting block 23 is inserted into the interior of the circular limiting groove 24. The circular limiting block 23 is pressed downward by the spring 3 22, so that the circular limiting block 23 is inserted into the interior of the circular limiting groove 24, and then the annular mounting plate 4 is limited and fixed, so that the annular mounting plate 4 is fixedly mounted on the box body 1, thereby preventing the annular mounting plate 4 and the filter element 3 from rotating and affecting the powder recovery work;

[0034] It should be noted that when the annular mounting plate 4 needs to be disassembled, the four rotating abutment blocks 21 need to be moved upward first, so that the rotating abutment blocks 21 drive the circular limit blocks 23 to move out from the inside of the circular limit groove 24. At this time, the annular mounting plate 4 loses its limiting and fixing effect, and the annular mounting plate 4 can be moved laterally, thereby driving the L-shaped limit blocks 15 and the tooth plate 16 to move laterally, and then the L-shaped limit blocks 15 are rotated to the notch where they can be moved vertically, so that the annular mounting plate 4 and the filter element 3 can be moved vertically upward out of the box body 1, and the disassembly of the filter element 3 is completed.

[0035] An annular fixing plate 5 is provided on the circumferential outer surface of the lower end of the filter element 3, and storage boxes 6 are provided on both left and right ends of the upper surface of the annular fixing plate 5, and the upper end of the storage box 6 is connected to the lower surface of the annular mounting plate 4, and a movable plate 7 is movably installed inside the storage box 6, and an accordion cover 8 is provided at the inner end of the movable plate 7, and the other end of the accordion cover 8 is connected to the inside of the storage box 6;

[0036] It should be noted that when the movable plate 7 is partially located inside the storage box 6, the storage box 6 can be closed to prevent powder from entering the storage box 6 and affecting the subsequent disassembly of the filter element 3 when the powder recovery work is carried out inside the box body 1. At the same time, the accordion cover 8 is folded and stored inside the storage box 6. When the two movable plates 7 are moved to abut against the other side of the storage box 6, the movable plates 7 will drive the accordion cover 8 to unfold, so that the two sets of accordion covers 8 completely wrap the filter element 3. Then, when the filter element 3 is disassembled, the dust attached to the side of the filter element 3 cannot float in the working environment, so as to avoid polluting the working environment or damaging the health of the staff.

[0037] A servo motor 28 is provided at the left end of the upper surface of the housing 1, and the power output end of the servo motor 28 is connected to a rotating shaft 29 through a coupling transmission, and the rotating shaft 29 is rotatably installed inside the housing 1, and a rotating gear 30 is provided on the circumferential surface of the rotating shaft 29, and an L-shaped rotating ring 31 is meshed and connected to the left side of the rotating gear 30 through an annular rack, wherein the annular rack and the L-shaped rotating ring 31 are arranged outside the spur gear 18, so that when the rotating gear 30 drives the annular rack and the L-shaped rotating ring 31 to rotate, the L-shaped rotating ring 31 will not contact with the spur gear 18 to affect the rotation. The left and right sides of the lower surface of the L-shaped rotating ring 31 are both provided with mounting plates 32, and the sides of the two storage boxes 6 away from the filter element 3 are both provided with connecting plates 34, and the connecting plates 34 are provided with elastic telescopic rods 35 inside, and the telescopic ends of the elastic telescopic rods 35 are provided with pulling plates 36, and the pulling plates 36 are L-shaped in design, and the sides of the two mounting plates 32 close to the filter element 3 are respectively fixedly connected to the two connecting plates 34, and the surfaces of the two mounting plates 32 away from the filter element 3 are both provided with cleaning brushes 33, and the cleaning brushes 33 are in contact with the inner wall of the box body 1;

[0038] It should be noted that after the dust inlet pipe 2 finishes collecting dust, the servo motor 28 drives the rotating shaft 29 and the rotating gear 30 to rotate, so that the rotating gear 30 drives the annular rack and the L-shaped rotating ring 31 to rotate, and then the L-shaped rotating ring 31 drives the mounting plate 32 and the cleaning brush 33 to rotate, so that the cleaning brush 33 cleans the inner wall of the box body 1, thereby sweeping down the powder attached to the upper end of the inner wall of the box body 1, and then collecting it, reducing the waste of powder, and at the same time, when the filter element 3 is disassembled later, it can reduce or avoid the powder from floating in the working environment and polluting the environment.

[0039] A lifting cylinder 41 is provided on the upper surface of the box body 1, and two lifting cylinders 41 are provided in a circumferential array. The lower ends of the two lifting cylinders 41 are provided with arc-shaped push plates 42, and the two arc-shaped push plates 42 are both provided above the pulling plate 36 and located inside the box body 1. The side walls of the two arc-shaped push plates 42 are provided with arc-shaped push blocks 43, and the two ends of the arc-shaped push blocks 43 are both arc-shaped. The arc-shaped design of the ends of the arc-shaped push blocks 43 enables the pulling plate 36 to be flush with the arc-shaped push blocks 43. When the pulling plate 36 is rotated horizontally to abut against the arc-shaped push blocks 43, the arc-shaped push blocks 43 can push the pulling plate 36 toward the filter element 3.

[0040] It should be noted that when the filter element 3 does not need to be removed, the arc-shaped push plate 42 and the arc-shaped push block 43 are above the pulling plate 36, so that when the installation plate 32 drives the pulling plate 36 to rotate horizontally, the pulling plate 36 will not contact the arc-shaped push block 43. When the filter element 3 needs to be removed, the lifting cylinder 41 works to drive the arc-shaped push plate 42 and the arc-shaped push block 43 to move downward to be flush with the pulling plate 36. Then, when the installation plate 32 drives the pulling plate 36 to move horizontally, the pulling plate 36 abuts against the arc-shaped push block 43, and the arc-shaped push block 43 will push the pulling plate 36 toward the filter element 3. The pulling plate 36 is pushed in the direction of the filter core 3, so that the end of the pulling plate 36 close to the filter core 3 is inserted into the inside of the first slot 9, and then when the pulling plate 36 continues to rotate, it can drive the movable plate 7 to move in an arc, so that the movable plate 7 drives the accordion cover 8 to unfold and wrap the filter core 3, and then after the pulling plate 36 rotates to the other end of the arc-shaped pushing block 43, the movable plate 7 abuts against the other side of the corresponding storage box 6, and after the pulling plate 36 loses the abutment of the arc-shaped pushing block 43, it is reset under the action of the elastic telescopic rod 35, and then when the pulling plate 36 continues to rotate, it will no longer push the movable plate 7 to move.

[0041] The two connecting plates 34 are both provided with a second mounting plate 37 at one end close to the filter element 3, and the two mounting plates 37 are both provided with a second cleaning brush 38 at one side close to the filter element 3. The second mounting plate 37 and the second cleaning brush 38 are both L-shaped in design, and the vertical surfaces of the two second cleaning brushes 38 are respectively in contact with the outer surfaces of the two storage boxes 6, and the upper surfaces of the bottoms of the two second cleaning brushes 38 are in contact with the lower surface of the filter element 3;

[0042] It should be noted that after the dust inlet pipe 2 finishes collecting dust, the mounting plate 1 32 drives the mounting plate 2 37 to rotate through the connecting plate 34, so that the mounting plate 2 37 drives the cleaning brush 2 38 to rotate, and then the cleaning brush 2 38 cleans the outer surface of the storage box 6 and the bottom of the filter element 3, thereby cleaning the powder attached to the outer surface of the storage box 6 and cleaning the powder slightly attached to the surface of the filter element 3. When the filter element 3 is subsequently disassembled, the powder is prevented from adhering to the outer surface of the storage box 6, which may cause the powder to float in the working environment during disassembly, polluting the environment or harming the health of the staff.

[0043] A vertical limit groove 25, a horizontal limit groove 26 and a rotation groove 27 are provided inside the upper end of the box body 1, and the vertical limit groove 25, the horizontal limit groove 26 and the rotation groove 27 are connected to each other. The vertical limit groove 25 and the horizontal limit groove 26 are matched with the L-shaped limit block 15, and the L-shaped limit block 15 is arranged at the connection between the horizontal limit groove 26 and the rotation groove 27. The arrangement of the horizontal limit groove 26 enables the L-shaped limit block 15 to rotate horizontally inside the horizontal limit groove 26. The arrangement of the vertical limit groove 25 enables the L-shaped limit block 15 to move vertically inside the vertical limit groove 25 after all of the L-shaped limit blocks 15 are located inside the vertical limit groove 25, thereby enabling the L-shaped limit block 15 to move out of the box body 1 or move into the box body 1. The spur gear 18 is arranged inside the rotation groove 27. The arrangement of the rotation groove 27 provides a movable space for the spur gear 18, so that the spur gear 18 can rotate smoothly.

[0044] The interior of the movable plate 7 is provided with a first slot 9, a through slot 11, and a second slot 10, which are connected to each other. The end portion above the pulling plate 36 matches the first slot 9. The setting of the first slot 9 enables one end of the pulling plate 36 to be smoothly inserted into the first slot 9, and then the pulling plate 36 can stably drive the movable plate 7 to move. A plug-in board 12 is provided on the side of the outer side of the storage box 6 away from the movable plate 7. The interior of the plug-in board 12 is movably connected with a plug-in block 14 through a spring 13. The plug-in board 12 matches the second slot 10, and the plug-in block 14 is connected to the movable plate 7. 14 matches the through slot 11, and the arrangement of the plug-in board 12 and the second slot 10 enables one of the movable plates 7 to move to abut against the outer side of another storage box 6, so that the plug-in board 12 on the storage box 6 can be inserted into the second slot 10, and then after the pulling plate 36 is moved out of the first slot 9, the part of the plug-in block 14 can be inserted into the first slot 9 through the through slot 11 under the action of the spring 13, and then the movable plate 7 is fixed to prevent the movable plate 7 from moving, so that the accordion cover 8 can completely wrap the filter element 3 at this time, which is convenient for the subsequent removal of the filter element 3;

[0045] It should be noted that the end of the plug block 14 away from the storage box 6 is designed to be arc-shaped, and the end close to the storage box 6 is designed to be right-angled, so that when the movable plate 7 moves to the plug board 12, the plug board 12 can be inserted into the interior of the movable plate 7, and the plug block 14 is squeezed and can be moved into the interior of the plug board 12. Then, after the pulling plate 36 is moved out from the inside of the first slot 9, the plug block 14 is inserted into the inside of the first slot 9 through the through groove 11. Because of the right-angle design at one end, the plug block 14 can stably lock the movable plate 7 on the storage box 6 to prevent the movable plate 7 from resetting and affecting the wrapping effect of the accordion cover 8.

[0046] A second rotating groove 39 and a third rotating groove 40 are provided inside the upper end of the housing 1, and the second rotating groove 39 and the third rotating groove 40 are communicated with each other. The rotating gear 30 is arranged inside the second rotating groove 39. The setting of the second rotating groove 39 provides a movable space for the rotating gear 30, so that the rotating gear 30 can rotate stably. The L-shaped rotating ring 31 and the annular rack are both arranged inside the rotating groove 3 40. The setting of the rotating groove 3 40 provides a movable space for the L-shaped rotating ring 31 and the annular rack, so that the L-shaped rotating ring 31 and the annular rack can rotate smoothly.

[0047] When the present invention is in use, after the dust inlet pipe 2 finishes collecting dust, the servo motor 28 is first turned on, and the servo motor 28 drives the rotating shaft 29 and the rotating gear 30 to rotate, so that the rotating gear 30 drives the annular rack and the L-shaped rotating ring 31 to rotate, and then the L-shaped rotating ring 31 drives the mounting plate 1 32 and the cleaning brush 1 33 to rotate, so that the cleaning brush 1 33 cleans the inner wall of the box body 1, thereby cleaning the powder attached to the upper end of the inner wall of the box body 1, and at the same time, the mounting plate 1 32 drives the mounting plate 2 37 to rotate through the connecting plate 34, so that the mounting plate 2 37 drives the cleaning brush 2 38 to rotate, and then the cleaning brush 2 38 cleans the outer surface of the storage box 6 and the bottom of the filter element 3, and cleans the powder attached to the outer surface of the storage box 6, and at the same time, cleans the powder slightly attached to the surface of the filter element 3, and then sweeps and collects the powder attached to the inner wall of the box body 1 and the outer surface of the storage box 6, thereby reducing the waste of powder;

[0048] Then, the lifting cylinder 41 is started, and the lifting cylinder 41 drives the arc-shaped push plate 42 and the arc-shaped push block 43 to move downward until they are flush with the pulling plate 36. At this time, the servo motor 28 is started again, so that the servo motor 28 rotates slowly. At this time, the servo motor 28 drives the connecting plate 34 and the pulling plate 36 inside it to rotate horizontally. After the pulling plate 36 abuts against the arc-shaped push block 43, the arc-shaped push block 43 pushes the pulling plate 36 toward the filter element 3, so that the end of the pulling plate 36 close to the filter element 3 is inserted into the first slot 9. Then, when the pulling plate 36 continues to rotate, it can drive the moving plate 7 to move in an arc, so that the moving plate 7 drives the accordion cover 8 to unfold and wrap the filter element 3, and then the pulling plate 36 rotates. After moving to the other end of the arc-shaped push block 43, the moving plate 7 abuts against the other side of the other storage box 6, so that the plug-in plate 12 on this storage box 6 is inserted into the inside of the moving plate 7, and the lifting cylinder 41 is started again to drive the arc-shaped push plate 42 and the arc-shaped push block 43 to move upward. After the pulling plate 36 loses the abutment of the arc-shaped push block 43, it is reset under the action of the elastic telescopic rod 35, and then the pulling plate 36 will no longer push the moving plate 7 to move when it continues to rotate. After the pulling plate 36 moves out of the inside of the first slot 9, the part of the plug-in block 14 inside the plug-in plate 12 can be inserted into the inside of the first slot 9 through the through slot 11 under the action of the spring 13, and then the moving plate 7 is fixed to prevent the moving plate 7 from moving;

[0049] Then move the four rotating abutment blocks 21 upward, so that the rotating abutment blocks 21 drive the circular limit blocks 23 to move out from the inside of the circular limit groove 24. At this time, the annular mounting plate 4 loses its limiting and fixing effect. Then move the annular mounting plate 4 horizontally, so that the L-shaped limit block 15 moves as a whole to the vertical limit groove 25. At this time, move the annular mounting plate 4 and the filter element 3 vertically upward, so that they can be moved out of the box body 1, and the disassembly of the filter element 3 is completed.
