Detailed Implementation

[0035] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] like Figure 1-13 As shown, the present invention provides a water curtain type water swirl spray booth, including a spray booth 1. The top of the spray booth 1 is provided with a blower 2, and the lower end of the spray booth 1 is provided with a first water tank 3. A water swirl device 4 is provided in the first water tank 3. The lower end of the first water tank 3 is provided with a second water tank 5 that cooperates with the water swirl device 4. One side of the second water tank 5 is provided with an exhaust fan 8 that cooperates with the blower 2. The other side of the second water tank 5 is provided with a water pump 9. The outlet pipe of the water pump 9 is connected to a dirt remover 10. The lower end of the dirt remover 10 is provided with a water curtain cabinet 11.

[0037] like Figure 1-2 As shown, spray booth 1 is the worker's spray booth, which is existing technology and will not be described in detail. When the worker is spraying paint on the workpiece, they face the direction of the water curtain cabinet 11. Part of the paint mist sprayed from the spray gun will adhere to the outer surface of the workpiece, while part will diffuse into the spray booth or impact the water curtain cabinet 11. The blower 2 on the spray booth can blow the paint mist diffused into the spray booth downwards. The bottom of the spray booth is equipped with a grid, which allows the worker to stand on while working, and also enables water circulation and air circulation. The first water tank 3 and the second water tank 5 are both filled with circulating water. Through the conveying of the blower 2, the paint mist can be transported to the first water tank 3, thereby mixing the paint mist with the circulating water, purifying the air, and allowing it to pass through under the action of the wind. The water vortex 4 mixes the air containing paint mist with water, dissolving the paint mist particles in the air into the water. It also guides the water in the first water tank 3 into the second water tank 5. The water vortex 4 is existing technology and will not be described in detail. With the cooperation of the blower 2 and the exhaust fan 8, the air in the spray booth can be purified by the water vortex 4 and discharged to the outside, increasing air circulation. The water pump 9 lifts the water in the second water tank 5 and delivers it to the impurity remover 10. The water in the impurity remover 10 falls onto the water curtain cabinet 11 under the action of gravity, forming a water curtain on one end of the water curtain cabinet 11, which can block or absorb excess paint mist sprayed from the spray gun. The water will then fall back into the first water tank 3 under the action of gravity, thus forming a water circulation.

[0038] The second water tank 5 has an air outlet 7 on one side, the exhaust fan 8 is installed at the air outlet 7, the water inlet pipe of the water pump 9 is connected to the bottom of the second water tank 5, and one end face of the water curtain cabinet 11 is an arc-shaped convex surface.

[0039] like Figure 2 As shown, the exhaust fan 8 and the blower 2 are existing technologies and will not be described in detail. The water in the second water tank 5 can be transported to the impurity remover 10 through the water pump 9, thereby realizing water circulation. The water pump 9 is existing technology and will not be described in detail. Through the arc-shaped convex surface of the water curtain cabinet 11, the water in the impurity remover 10 can flow along the arc-shaped convex surface when it falls down onto the water curtain cabinet 11, forming an arc-shaped water curtain, which can increase the area for receiving paint mist, save space, and does not affect the flow rate of water circulation.

[0040] The impurity remover 10 includes a water tank 12, a filter plate 19 is fixedly connected to the inner wall of the water tank 12, and an outlet box 15 is provided at the lower end of the water tank 12. The outlet box 15 is located at the upper end of the water curtain cabinet 11. The filter plate 19 is provided with a scraper 22 that can move left and right. A collection groove 39 that cooperates with the scraper 22 is provided on one side of the filter plate 19. A rotatable cylindrical cam 31 is provided on the left side of the water tank 12. When the cylindrical cam 31 rotates, it can form a structure in which the collection groove 39 moves upward and then forward and flips.

[0041] like Figure 3-4 As shown in Figures 9-10, the water tank 12 is fixed on the inner wall of the spray booth 1. The outlet pipe of the water pump 9 is connected to the upper port of the water tank 12. The water falls into the water tank 12 by its own gravity and then passes through the filter plate 19, so that the impurities in the water are filtered onto the filter plate 19. The filtered water falls into the outlet box 15 and the water curtain cabinet 11 by its own gravity. The scraper 22, which can move left and right, can push the impurities on the upper end of the filter plate 19 into the collection tank 39 when it moves. Then, by rotating the cylindrical cam 31, the collection tank 39 can move upward and then forward and flip over, so that the impurities are removed from the device.

[0042] A first motor 13 is fixedly connected to the right end surface of the water tank 12. A disc 14 is fixedly connected to the upper end of the first motor 13. A first sliding pin 16 is fixedly connected to the non-center part of the upper end surface of the disc 14. A first connecting rod 18 is slidably connected to the inner wall of the right end of the water tank 12. A key plate 17 that cooperates with the first sliding pin 16 is fixedly connected to the right end surface of the first connecting rod 18. The scraper 22 is installed on one side of the first connecting rod 18.

[0043] like Figure 3-6 As shown, the function of the first motor 13 is to provide rotational power to the disk 14. The motor is existing technology and will not be described further. The first connecting rod 18 is slidably connected to the inner wall of the right end of the water tank 12, as shown in the diagram. Figure 6 As shown, the key plate 17 can be moved back and forth left and right by engaging with the first sliding pin 16. When it is necessary to remove impurities from the upper surface of the filter plate 19, the first motor 13 is started, which will cause the disc 14 to rotate. The rotation of the disc 14 will cause the first sliding pin 16 to rotate circumferentially by engaging with the first sliding pin 16. When the first sliding pin 16 rotates circumferentially, it will cause the key plate 17 and the first connecting rod 18 to move back and forth left and right by engaging with the key plate 17, which will in turn cause the scraper 22 to move back and forth left and right.

[0044] A U-shaped slide plate 21 is slidably connected to the upper surface of the water tank 12. A connecting rod 20 is hinged to the middle of the U-shaped slide plate 21. The other end of the first connecting rod 18 is hinged to the connecting rod 20. The scraper 22 is fixed to the lower surface of the connecting rod 20. A first stop pin 23 that cooperates with the connecting rod 20 is provided on the lower surface of the U-shaped slide plate 21. A second stop pin 24 that cooperates with the connecting rod 20 is provided on the upper surface of the U-shaped slide plate 21.

[0045] like Figure 6-8As shown, the U-shaped slide plate 21 is slidably connected to the upper surface of the water tank 12. The outer surfaces of the first stop pin 23 and the second stop pin 24 are respectively fixed with mounting seats, which are fixed to the U-shaped slide plate 21. The second stop pin 24 and the first stop pin 23 are respectively installed on the upper and lower sides of the hinge point between the U-shaped slide plate 21 and the connecting rod 20. When the first connecting rod 18 moves to the left, it drives the corresponding connecting rod 20 to move to the left. Since the hinge point between the first connecting rod 18 and the connecting rod 20 is located at the lower end of the connecting rod 20 and the U-shaped slide plate 21, when the first connecting rod 18 pushes the connecting rod 20 to the left, it drives the connecting rod 20 to swing to the left first. The connecting rod 20 swings to the left until the scraper 22 contacts the upper surface of the filter plate 19, after which it stops swinging to the left. That is, at this time, the connecting rod 20 contacts the first stop pin 23. 23. The function of the second stop pin 24 is to prevent the connecting rod 20 from swinging excessively. When the first connecting rod 18 pushes the connecting rod 20, the U-shaped slide plate 21, and the scraper 22 to the leftmost end, even if the impurities on the upper end of the filter plate 19 are pushed into the collection tank 39, the first connecting rod 18 will move to the right in the opposite direction. The movement of the first connecting rod 18 to the right will drive the corresponding connecting rod 20 to swing to the right first. When the connecting rod 20 swings to the right, it will drive the scraper 22 to swing to the right. When the connecting rod 20 swings to the right and meets the second stop pin 24, the scraper 22 will no longer contact the filter plate 19, that is, there is a certain gap between it and the filter plate 19. When the first connecting rod 18 moves to the left, it will pull the corresponding scraper 22 to move to the left, thereby achieving a reset and preventing the scraper 22 from scraping the impurities on the upper end of the filter plate 19 back to the left end of the filter plate 19.

[0046] The water tank 12 has an extension platform 26 on its left end surface. A first support plate 27 is slidably connected to the upper end surface of the extension platform 26. A second motor 28 is fixedly connected to the upper end surface of the first support plate 27. A first bevel gear 29 is fixedly connected to the left end of the second motor 28. A second bevel gear 30 is meshed with the left end of the first bevel gear 29. A cylindrical cam 31 is coaxially fixed to the upper end of the second bevel gear 30. A second sliding pin 32 is meshed with the outer surface of the cylindrical cam 31. A long sliding rod 33 is fixedly connected to the outer surface of the second sliding pin 32. An inner slider 34 fixed to the first support plate 27 is slidably connected to the inner wall of the long sliding rod 33. The collection groove 39 is installed on the long sliding rod 33.

[0047] like Figure 9-12 As shown, the first support plate 27 is slidably connected to the upper surface of the extension platform 26. A rotating shaft is coaxially fixed to the inner wall of the second bevel gear 30 and the cylindrical cam 31. The rotating shaft is rotatably connected to the inner wall of the first support plate 27, limiting the cylindrical cam 31 to rotate only on the first support plate 27. The cylindrical cam 31, the second sliding pin 32, the long sliding rod 33, and the inner slider 34 are installed and shaped as follows: Figure 11-12As shown, the inner slider 34 limits the movement of the long slide rod 33, allowing it to move only up and down. The outer surface of the cylindrical cam 31 has two sections: a V-shaped groove and a flat arc groove. When the second slide pin 32 engages with the V-shaped groove of the cylindrical cam 31, it will move up and down. When the second slide pin 32 engages with the flat arc groove, it will remain stationary. Therefore, through the engagement of the cylindrical cam 31 and the second slide pin 32, when the cylindrical cam 31 rotates, the second slide pin 32 will first move upward, then remain stationary for a short period, and then move downward to reset. When the second motor 28 starts, the engagement of the first bevel gear 29 and the second bevel gear 30 will cause the cylindrical cam 31 to rotate. The rotation of the cylindrical cam 31, through its engagement with the second slide pin 32, will cause the second slide pin 32, the long slide rod 33, and the collecting groove 39 to move upward, then remain stationary for a period, and then move downward.

[0048] The upper end of the cylindrical cam 31 is coaxially fixed to a planar cam 36, and the upper surface of the planar cam 36 is engaged with a third sliding pin 37. The upper surface of the extension platform 26 is fixed to an L-shaped seat 35, and the third sliding pin 37 is fixed to the inner wall of the L-shaped seat 35.

[0049] like Figure 11 As shown, the L-shaped seat 35 serves to support and fix the third sliding pin 37. The third sliding pin 37 and the flat cam 36 are installed and shaped as follows: Figure 11 As shown, through the engagement of the planar cam 36 and the third sliding pin 37, the planar cam 36, when rotating, causes the first support plate 27, cylindrical cam 31, planar cam 36, and collecting groove 39 to move synchronously and intermittently back and forth. The planar cam 36 has a sector-shaped groove section and an elliptical groove section. When the planar cam 36 rotates, i.e., when the third sliding pin 37 engages with the planar cam 36, i.e., when the third sliding pin 37 is in the sector-shaped groove section, the planar cam 36 will first remain stationary for a short period of time. When the third sliding pin 37 engages with the corresponding elliptical groove, the planar cam 36 will move forward and then backward. When the planar cam 36 continues to rotate, the third sliding pin 37 will enter the sector-shaped groove section, i.e. The corresponding planar cam 36 returns to rest; therefore, through the cooperation of the cylindrical cam 31 and the planar cam 36, the corresponding collection trough 39 can present an L-shaped motion trajectory. Even if the collection trough 39 moves upward first, moves to the top and then moves forward, even if the collection trough 39 moves upward to the upper position of the water tank 12, it prevents the collection trough 39 from obstructing the movement of the water tank 12. Even if the collection trough 39 moves forward, even if one end of the collection trough 39 moves to the outside of the water tank 12, it prevents the impurities from falling back into the water tank 12 when they are poured out. After moving forward to the top, it moves backward, and after moving backward to the top, it moves downward to reset, thereby removing the impurities in the collection trough 39 from the device.

[0050] The lower end surface of the long sliding rod 33 is fixedly connected to a second support plate 38. The collection groove 39 is hinged to the second support plate 38. A spur gear 40 is also coaxially fixed to the left side of the collection groove 39. A spur rack 41 that cooperates with the spur gear 40 is fixedly connected to the extension platform 26. A sealing cover 42 is hinged to the front end of the inner wall of the collection groove 39. An extension rod 43 is provided at the upper end of the sealing cover 42. The other end of the extension rod 43 is hinged to a limiting link 44. The other end of the limiting link 44 is hinged to the second support plate 38. A container 45 that cooperates with the collection groove 39 is provided on the front surface of the extension platform 26.

[0051] like Figure 6 , 12 As shown, a filter tray 25 is fixed to the left end surface of the filter plate 19, creating a downwardly recessed space at the left end of the filter plate 19 for storing the collection tank 39. This allows the collection tank 39 to be slightly lower than the filter plate 19, facilitating the scraper 22 to convey impurities into the collection tank 39. The filter tray 25 also prevents impurities from falling into the lower part of the water tank 12. The second support plate 38 supports and limits the collection tank 39, allowing it to rotate on the second support plate 38. Figure 12 As shown, the collection trough 39 is hinged to the front end of the second support plate 38. A support bracket is fixed to the rear side of the upper surface of the second support plate 38, and the top of the support bracket contacts the bottom of the collection trough 39. Supported by the support bracket, the collection trough 39 can be kept horizontal under normal conditions, thus facilitating the collection of impurities. A rotating shaft is fixed to the inner wall of the spur gear 40, and the rotating shaft is rotatably connected to the inner wall of the collection trough 39. A bearing seat is rotatably connected to the outer surface of the rotating shaft, and the bottom end of the bearing seat is fixed to the second support plate 38, effectively making the collection trough 39 hinged to the second support plate 38. When the long slide rod 33 moves the second support plate 38 upward, it also drives the collection trough 39 and the spur gear 40 to move upward synchronously. When the long slide rod 33 moves the second support plate 38 forward, it also drives the collection trough 39 and the spur gear 40 to move upward synchronously. As the device moves forward, when the spur gear 40 moves forward and meets the rack 41, it continues to move forward. The spur gear 40 will rotate due to its meshing with the rack 41. The rotation of the spur gear 40 will cause the collection tank 39 and the sealing cover 42 to flip synchronously. When the sealing cover 42 flips, it will be driven by the extension rod 43 and the limiting link 44 to flip the sealing cover 42 upward along the collection tank 39, thereby opening one end of the collection tank 39. The impurities will fall into the container 45 under the action of gravity, thus removing the impurities from the device. The bottom inner wall of the collection tank 39 is provided with a small through hole to prevent the collection tank 39 from carrying water out of the water tank 12 when it moves upward. The container 45 and the extension platform 26 are connected by a left-right sliding connection, and the container 45 is easy to disassemble and clean.

[0052] A method for using a water curtain type water swirl spray booth includes the following steps:

[0053] S1, through the operation of the blower 2 and the exhaust fan 8, allows the gas and paint mist in the spray booth 1 to sequentially enter the first water tank 3 and the water vortex 4, and then be discharged from the air outlet 7; thereby completing the purification treatment of the paint mist and gas in the spray booth.

[0054] When the water pump 9 starts, S2 will transport the water in the second water tank 5 to one end of the water curtain cabinet 11 to form an arc-shaped water curtain; thereby purifying the excess paint mist sprayed from the spray gun.

[0055] When the circulating water passes through the impurity remover 10, S3 starts the first motor 13, which causes the scraper 22 to scrape the impurities in the water to the left and transport them to the collection tank 39. Then, the second motor 28 is started, which causes the collection tank 39 to move upward and then forward and flip over, so that the impurities in the collection tank 39 are removed from the equipment; thus completing the impurity removal treatment of the circulating water.

[0056] In use, the gas and paint mist in the spray booth 1 are sequentially drawn into the first water tank 3 and the water vortex 4 by the operation of the blower 2 and the exhaust fan 8, and discharged from the air outlet 7, thereby completing the purification treatment of the paint mist and gas in the spray booth. When the water pump 9 is started, the water in the second water tank 5 is transported to one end of the water curtain cabinet 11 to form an arc-shaped water curtain, thereby purifying the excess paint mist sprayed from the spray gun. When the circulating water passes through the impurity remover 10, the first motor 13 is started, which causes the scraper 22 to scrape the impurities in the water to the left and transport them to the collection tank 39. Then the second motor 28 is started, which causes the collection tank 39 to move upward and then forward and flip over, so that the impurities in the collection tank 39 are removed from the equipment, thereby completing the impurity removal treatment of the circulating water.
