Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, and specifically to a dust reduction and purification device for gas spring tubing surface coating treatment. Background Technology

[0002] In the production of gas springs, tubular components are used, and surface coating is a crucial process in tubular processing. Surface coating can enhance various properties of the tubular material. However, the coating process generates gases that can pollute the surrounding air. To prevent these gases from entering the air and affecting human health, existing dust suppression and purification devices are used. However, these devices are separate from the coating process; they can only extract gases from the coating work area. The coated tubing, before it dries, will continue to release gases, further polluting the surrounding air. Summary of the Invention

A flipping plate is rotatably disposed inside the opening of the inlet and sleeved outside the output shaft of the flipping motor. A cylindrical through hole is provided on the flipping plate to facilitate placing the pipe on the flipping plate.

[0006] Preferably, a circular electromagnet is coaxially arranged on the inner peripheral wall of the cylindrical through hole to prevent the magnetic material tube from falling out of the cylindrical through hole.

[0007] Preferably, two coating spray plates are provided. The coating spray plates have a hollow structure and are connected to the coating liquid tank set on the outer wall of the coating box through a flexible tube. Semi-circular grooves are provided on the opposite side walls of the two coating spray plates. The arc-shaped openings of the semi-circular grooves on the two coating spray plates are opposite each other. Multiple coating nozzles are connected on the semi-circular inner peripheral wall of the semi-circular grooves, which is conducive to spraying the surface of the pipe through the coating nozzles.

[0010] Preferably, the coating box is equipped with a water tank with a water pump connected to the spray plate. The bottom surface of the spray tank is a screen-like structure. An exhaust trough is provided at the bottom of the inner wall of the spray tank away from the dust-collecting arc plate. A filter box connected to the exhaust trough is provided on the outer wall of the coating box. An exhaust pipe is provided at the top of the filter box. The gas generated after the pipe surface is coated is sprayed in the spray tank, enters the filter box through the exhaust trough, is filtered, and then discharged through the exhaust pipe.

[0011] Preferably, the upper chuck comprises: A tilting motor is installed on the outer wall of the top opening of the inlet pipe. A tilting base is mounted on the output shaft of a tilting motor. Chuck cylinder, the chuck cylinder is mounted on the tilting seat; The large-diameter end of the truncated cone chuck is coaxially mounted on the output shaft of the flipping motor, and the position of the truncated cone chuck is adapted to the position of the cylindrical through hole.

The return spring has two ends connected to the ring and the base respectively. Depending on the structure of the pipe, the ring or the frustum-shaped end of the top can be used to abut against the pipe, thereby clamping and fixing the pipe placed in the cylindrical channel in conjunction with the frustum clamp.

[0014] The beneficial effects of the present invention are as follows: 1. By arranging the coating spray plate and the spray box sequentially from top to bottom inside the coating box, it is convenient to spray and purify the exhaust gas generated during pipe coating, thereby avoiding or reducing the exhaust gas from being discharged into the air and thus reducing the harm to the air.

[0015] 2. Depending on the pipe structure, when the pipe is solid, the small-diameter end of the frustum clamp abuts against one end of the pipe; simultaneously, the circular surface of the annulus away from the base abuts against the other end of the pipe, until the frustum end of the top end passes through the inner circle of the cylindrical sleeve and the annulus and abuts against the other end of the pipe, thus clamping the solid pipe. When the pipe is hollow, the small-diameter end of the frustum clamp can penetrate into the interior of one end of the pipe, at which point the outer circumferential wall of the small-diameter end of the frustum clamp abuts against the inner circumferential wall of one end of the pipe; simultaneously, the circular surface of the annulus away from the base abuts against the other end of the pipe, and the frustum end of the top end can pass through the inner circle of the cylindrical sleeve and the annulus to the other end of the pipe, at which point the outer circumferential wall of the frustum end of the top end abuts against the inner circumferential wall of the other end of the pipe, thus clamping the hollow pipe, thereby increasing the versatility of pipe clamping.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1 like Figures 1 to 2 , Figures 4 to 7 , Figure 11As shown, this invention provides a dust suppression and purification device for surface coating treatment of gas spring tubing, including a coating box 1 with an inlet 11 on its top surface; a spray box 2 disposed on the bottom surface inside the coating box 1; multiple coating spray plates 3 symmetrically arranged above the spray box 2; a tubing adjusting rod assembly 4 disposed below the coating box 1; the spray box 2 includes a base 21 disposed on the bottom surface inside the coating box 1, a cylindrical channel 22 vertically disposed inside the base 21, and multiple dust-collecting arc-shaped plates 23 evenly distributed circumferentially on the inner peripheral wall of the cylindrical channel 22, the arc shape of the dust-collecting arc-shaped plates 23 being... Multiple dust suction ports 24 are provided on the inner peripheral wall of the opening. Spray tanks 25 are provided at opposite ends of the base 21. A spray plate 26 is provided at the top of the spray tank 25. Multiple spray heads 27 are provided on the bottom surface of the spray plate 26. A suction fan 28 is embedded in the inner wall of the spray tank 25 near the dust suction arc plate 23. The air inlet of the suction fan 28 is connected to the dust suction arc plate 23. The pipe adjusting rod assembly 4 includes an upper clamp 41 provided at the inlet 11 and a lifting rod 42 provided below the coating box 1. The positions of the upper clamp 41 and the lifting rod 42 are adapted to the position of the cylindrical channel 22.

[0032] The pipe is placed into the coating box 1 through the inlet 11 (at this time, the pipe can be clamped and fixed between the coating spray plates 3 by the combined action of the upper clamp 41 and the lifting rod 42). The pipe can then be coated under the action of the coating spray plates 3. After coating, the pipe can be moved into the cylindrical channel 22 in the base 21 by the combined action of the upper clamp 41 and the lifting rod 42. The dust-collecting arc plate 23 can absorb the exhaust gas generated after coating. The absorbed exhaust gas enters the spray tank 25 at both ends of the base 21 through the dust-collecting port 24 on the dust-collecting arc plate 23. Spray water is sprayed out through the spray head 27 on the spray plate 26 to spray the exhaust gas (the setting of the suction fan 28 is conducive to the exhaust gas entering the spray tank 25 through the dust-collecting port 24).

[0033] Alternatively, multiple coating spray plates 3, spray boxes 2, and corresponding number of pipe adjusting rod assemblies 4 can be arranged horizontally in parallel within the coating box 1 to simultaneously treat the exhaust gas generated during the coating operation of multiple pipes for dust reduction and purification.

[0034] Example 2 Based on Example 1, such as Figures 1 to 4 As shown, a flip motor 111 is provided on the outer wall of the inlet 11. The output shaft of the flip motor 111 is movably inserted into the opening of the inlet 11. A flip plate 112 is rotatably installed inside the opening of the inlet 11, which is sleeved on the outside of the output shaft of the flip motor 111. A cylindrical through hole 113 is provided on the flip plate 112. A circular electromagnet 114 is coaxially installed on the inner circumferential wall of the cylindrical through hole 113.

[0035] Before placing the pipe, the flipping motor 111 can be started to drive the flipping plate 112 to flip, thereby adjusting the orientation of the cylindrical through hole 113 on the flipping plate 112 to facilitate the placement of the pipe. When placing the pipe of magnetic material, after the pipe of magnetic material is inserted into the inner circle of the annular electromagnet 114 on the flipping plate 112, it can be attracted by the action of the annular electromagnet 114, so that the flipping plate 112 keeps the position stable when it drives the pipe of magnetic material to flip, and avoids the pipe of magnetic material from falling off.

[0036] Example 3 Based on Example 1, such as Figure 1 , Figures 3 to 5 , Figure 7 As shown, there are two coating spray plates 3. The coating spray plates 3 are hollow structures. The coating spray plates 3 are connected to the coating liquid tank 33 set on the outer wall of the coating box 1 through a hose. The two coating spray plates 3 are provided with semi-circular grooves 31 on opposite side walls. The arc-shaped openings of the semi-circular grooves 31 on the two coating spray plates 3 are opposite each other. Multiple coatings are connected on the semi-circular inner peripheral wall of the semi-circular groove 31. When the pipe is put into the coating box 1 from the inlet 11 (at this time, the pipe can be clamped and fixed in the arc-shaped opening of the semi-circular groove 31 on the coating spray plate 3 by the combined action of the upper clamp 41 and the lifting rod 42), the coating liquid in the coating liquid tank 33 is sprayed out through the coating nozzle 32 on the semi-circular groove 31 to spray the surface of the pipe. Since the semi-circular groove 31 is coaxial with the cylindrical through hole 113 and the coating nozzle 32 is set on the semi-circular inner peripheral wall of the semi-circular groove 31, it is beneficial to make the coating nozzle 32 spray the surface of the pipe evenly.

[0037] Example 4 Based on Example 1, such as Figures 1 to 4 , Figure 12 As shown, a coating liquid absorption pad 211 is provided on the top surface of the base 21. The coating liquid absorption pad 211 has through holes 212 that are adapted to the cylindrical channel 22. When coating the pipe, excess coating liquid can flow to the bottom of the coating box 1 (i.e., the top surface of the spray box 2), and the coating liquid can be absorbed by the coating liquid absorption pad 211, thereby reducing or preventing the coating liquid from flowing in the coating box 1, which facilitates the subsequent treatment of excess coating liquid.

[0038] Example 5 Based on Example 1, such as Figures 1 to 2 , Figures 4 to 5 , Figure 11As shown, the coating box 1 is equipped with a water tank 29 with a water pump connected to the spray plate 26. The bottom surface of the spray trough 25 is a screen-like structure. The bottom of the inner wall of the spray trough 25 away from the dust-collecting arc plate 23 is provided with an exhaust trough 251. The outer wall of the coating box 1 is provided with a filter box 252 connected to the exhaust trough 251. The top of the filter box 252 is provided with an exhaust pipe 253. The spray water in the water tank 29 with the water pump can enter the spray plate 26 and then be sprayed out through the spray head 27 on the spray plate 26 to spray the exhaust gas. The spray water can be filtered through the bottom surface of the spray trough 25 and then flow into the lower box 421. The exhaust gas after spraying can enter the filter box 252 through the exhaust trough 251, and then be filtered in the filter box 252 and discharged through the exhaust pipe 253.

[0039] Example 6 Based on Example 1, such as Figures 1 to 3 , Figure 5 , Figures 8 to 10 As shown, the upper chuck 41 includes a tilting motor 411, which is mounted on the outer wall of the top opening of the inlet 11; a tilting seat 412 is mounted on the output shaft of the tilting motor 411; a chuck cylinder 413 is mounted on the tilting seat 412; the large-diameter end of the frustum chuck 414 is coaxially mounted on the output shaft of the tilting motor 411, and the position of the frustum chuck 414 is adapted to the position of the cylindrical through hole 113; the lifting rod 42 includes a lower housing 421, which is located below the coating box 1. The top surface of the lower housing 421 is open, and a return groove 4211 connected to the water tank 29 with a water pump is provided on the bottom surface inside the lower housing 421; a lifting cylinder 422 is located inside the lower housing 421; and an extension rod 423 is coaxially mounted on the lifting cylinder 421. The piston rod of the extension rod 423 is mounted on the piston rod 2. The lifting head 424 is located at the end of the extension rod 423 away from the lifting cylinder 422. The lifting head 424 includes a base plate 4241, which is fixedly sleeved on the outside of the extension rod 423. The lifting head 4242 is coaxially located at the end of the extension rod 423 away from the lifting cylinder 422. The end of the lifting head 4242 away from the lifting cylinder 422 is a frustum-shaped structure, and the end of the lifting head 4242 near the lifting cylinder 422 is a cylindrical structure. The cylindrical sleeve 4243 is movably sleeved on the outside of the cylindrical end of the lifting head 4242. The annular body 4244 is located at the end of the cylindrical sleeve 4243 away from the lifting cylinder 422. The outer diameter of the annular body 4244 is adapted to the inner diameter of the cylindrical channel 22. The two ends of the return spring 4245 are connected to the annular body 4244 and the base plate 4241, respectively.

[0040] When the pipe is placed into the coating box 1 through the inlet 11, the pipe can be clamped and fixed by the combined action of the upper clamp 41 and the lifting rod 42 (when the clamp cylinder 413 is needed, the flip motor 411 can be started to drive the flip seat 412 to adjust the position). Depending on the length of the pipe, the frustum clamp 414 moves under the action of the clamp cylinder 413, so that the small diameter end of the frustum clamp 414 abuts against one end of the pipe; at the same time, the lifting cylinder 422 can drive the extension rod 423 and the lifting head 424 to adjust the position and abut against the other end of the pipe, thereby clamping and fixing the pipe.

[0041] Depending on the structure of the pipe, the frustum-shaped end of the ring 4244 or the jack 4242 can be used to abut against the pipe, thereby clamping and fixing the pipe placed in the cylindrical channel 22 in conjunction with the frustum-shaped chuck 414; that is, when the pipe is a solid structure, the small-diameter end of the frustum-shaped chuck 414 abuts against one end of the pipe; at the same time, when the lifting cylinder 422 can drive the extension rod 423 and the jack 424 to move closer to the pipe... When the other end moves, the circular surface of the ring 4244 away from the chassis 4241 can abut against the other end of the tube. As the lifting cylinder 422 continues to push, the return spring 4245 can be compressed until the frustum end of the top head 4242 can pass through the inner circle of the cylindrical sleeve 4243 and the ring 4244 and abut against the other end of the tube, thus achieving the clamping of the solid tube structure (the frustum chuck 414 and the top head 4242 are coaxial).

[0042] When the tube is hollow, the small-diameter end of the frustum chuck 414 can penetrate into the interior of one end of the tube. At this time, the outer peripheral wall of the small-diameter end of the frustum chuck 414 abuts against the inner peripheral wall of one end of the tube. At the same time, the circular surface of the end of the ring 4244 away from the chassis 4241 can abut against the other end of the tube. As the lifting cylinder 422 continues to push, the frustum end of the top head 4242 can pass through the inner circle of the cylindrical sleeve 4243 and the ring 4244 to the other end of the tube. At this time, the outer peripheral wall of the frustum end of the top head 4242 abuts against the inner peripheral wall of the other end of the tube, thus achieving the clamping of the hollow tube.

[0043] When the pipe is clamped and fixed in the arc-shaped opening of the semi-circular groove 31 on the two coating spray plates 3 under the combined action of the upper chuck 41 and the lifting rod 42 (at this time, the annular body 4244 can be located in the arc-shaped opening of the semi-circular groove 31 near the end of the seat 21, and an annular sealing ring can be provided on the outer peripheral wall of the annular body 4244 to improve the sealing performance and prevent the coating liquid from flowing into the cylindrical channel 22 when the pipe is coated in the arc-shaped opening of the semi-circular groove 31), the coating operation can be carried out. After the coating is completed, the chuck cylinder 413 is activated to push the frustum chuck 414 to move towards the lifting cylinder 422. At the same time, the lifting cylinder 422 drives the lifting rod 42 to move away from the chuck cylinder 413. At this time, the pipe can pass through the arc-shaped opening of the two semi-circular grooves 31 into the cylindrical channel 22 in the base 21 (that is, located in the arc-shaped opening of the dust suction arc plate 23) to complete the absorption and spraying operation of the exhaust gas. After the spraying is completed, the chuck cylinder 413 is started again to push the frustum chuck 414 to move closer to the lifting cylinder 422 (at the same time, the lifting cylinder 422 drives the lifting rod 42 to move away from the chuck cylinder 413 until the pipe moves to the outside of the cylindrical channel 22, and the pipe can be removed).

[0044] The spray water can be filtered through the bottom surface of the spray tank 25 and then flow into the lower tank 421. It can then be returned to the water tank 29 with a water pump through the return channel 4211 on the bottom surface of the lower tank 421 for recycling.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
