Description

Technical Field

[0001] The invention relates to the technical field of water curtain dust removal, in particular to a water curtain dust removal device for welding plate grinding. Background Art

[0002] Grinding refers to a processing method that uses grinding tools (including cutting tools, grinding tools and abrasives) to cut off the excess material layer on the blank or workpiece to make it into chips, so that the workpiece obtains the specified geometric shape, size and surface quality. Dust and other pollutants will be generated during the grinding process of welding plates. A large amount of dust will not only damage the environmental quality of the production workshop, but also damage the workers' respiratory tract, causing respiratory diseases and affecting their health. Therefore, most manufacturers will install water curtain dust removal devices in the workshop.

[0003] However, in actual applications, there are still some unresolved problems. The following are some common problems with water curtain dust removal devices: In most cases, multiple staggered guide plates are installed in the water curtain dust removal device to play a deflection role, so that after the nozzle sprays out to form a water curtain and falls, it can be deflected to form multiple water curtains to improve the dust removal effect. However, there are cases where particles adhere to the guide plates. First, the continuous deposition of dust particles on the surface of the guide plates will change the water flow path, resulting in uneven distribution of the water curtain and forming obvious gap areas, which will affect the effect of water curtain dust removal. Secondly, existing mechanical cleaning devices (such as rotating brushes) will destroy the continuity of the water curtain during operation, generate new air flow channels, and cause fluctuations in dust removal efficiency.

DETAILED DESCRIPTION

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0045] Example 1

[0046] Reference Figures 1 to 12, which is the first embodiment of the present invention, provides a water curtain dust removal device for welding plate grinding. The water curtain dust removal device for welding plate grinding includes a water curtain dust removal mechanism 1 and an adjustment mechanism 2. Through the cooperation of the water curtain dust removal mechanism 1 and the adjustment mechanism 2, the continuous deposition of dust particles on the surface of the air guide cover can be reduced, the uniformity of the water curtain distribution can be ensured, the formation of obvious gap areas can be reduced, and there is no need for mechanical cleaning devices to clean.

[0047] Specifically, the water curtain dust removal mechanism 1 includes a shell 11, and a water circulation component 12 is installed on the shell 11. The water circulation component 12 can filter and circulate the water in the shell 11 and spray it out from the top of the shell 11. It is a prior art. The working principle of this part is all prior art. Those skilled in the art can clearly know it and will not be elaborated here. The inner wall of the shell 11 is fixedly connected with a mesh cover 13, a mesh tube 14 and a vertical tube 15, and they are distributed from the outside to the inside.

[0048] Through the setting of the mesh cover 13, when the fan 18 is running, the dust generated by grinding is sucked into the shell 11, and the water sprayed by the water circulation component 12 is sprayed onto the mesh cover 13, forming a water curtain in the form of a waterfall flow on the mesh cover 13. Under the action of the mesh cover 13 to intercept and filter large particles of dust, the dust in the inhaled flowing gas is initially settled and dust-removed. Through the setting of the mesh cylinder 14, the dust gas after preliminary settlement passes through the gap between the mesh cover 13 and the mesh cylinder 14, and is captured and settled again in the water curtain formed by the water sprayed by the water circulation component 12.

[0049] The inner wall of the mesh tube 14 is fixedly connected to an airbag cover 16, the outer surface of the vertical tube 15 is fixedly connected to an airbag cover 2 17, and the top of the shell 11 is connected to a fan 18. There are multiple airbag covers 16 and 17. Through this arrangement, the falling water is deflected multiple times to form multiple water curtains, which can fully capture and settle the dust in the gas passing through them. The airbag covers 16 and 17 are inflatable and retractable airbags with smooth surfaces, which are existing technologies. The working principles of this part are all existing technologies, which can be clearly understood by those skilled in the art and will not be elaborated here. Through the arrangement of the vertical tube 15, the gas after being deflected and captured by multiple airbag covers 16 and 17 and settled is diverted and discharged under the action of the fan 18.

[0050] Specifically, the adjustment mechanism 2 is installed on the vertical cylinder 15 and is arranged on the mesh cylinder 14 and the shell 11. It includes an inflation and deflation member 21 fixedly connected to the inner wall of the vertical cylinder 15, and is arranged on the surface of the mesh cylinder 14, and is connected to the airbag cover 1 16 and the airbag cover 2 17. Through the setting of the inflation and deflation member 21, the shape of the airbag cover 1 16 and the airbag cover 2 17 can be changed, and it plays a guiding and deflecting role in the initial form after inflation. When the sediment collected on the ring plate 22-4 of the driving member 22 becomes heavier, the airbag cover 1 16 and the airbag cover 2 17 gradually expand and then change slightly, so that the contact point of the particles attached to its surface changes, and they are better separated under the action of hydraulic impact, reducing the gaps in the water curtain formed by the falling of particles attached to its surface, thereby improving the dust removal effect of the water curtain. The limiting groove 26 is respectively connected to the groove 23 and the groove body 29.

[0051] A driving member 22 is installed on the shell 11 and the mesh cylinder 14, and is arranged on the inflation and deflation member 21. Through the arrangement of the driving member 22, the dust captured by the water curtain between the mesh cylinder 14 and the vertical cylinder 15 can be collected. A mesh hole is provided at the lower end of the mesh cylinder 14, which will not affect the normal flow of water and can intercept the particulate matter settled and collected in the mesh cylinder 14. A groove 23, a limit groove 26 and a groove body 29 are respectively provided in the mesh cylinder 14. A trigger block 24 is slidably connected to the mesh cylinder 14, and one end of the trigger block 24 extends into the groove 23 and is fixedly connected to a spring 25. One end of the spring 25 is fixedly connected to the inner wall of the groove 23.

[0052] A slope is provided at one end of the trigger block 24. Through such a setting, the ring plate 22-4 can be squeezed to move after it moves down and contacts with it. The trigger block 24 is acted on by the setting of spring 1 25. As the dust removal progresses, the particulate matter of the airbag cover 1 16 and the airbag cover 2 17 may also increase. As the deposits on the ring plate 22-4 increase, the corresponding pressure in the air cylinder 21-1 is overcome, and it moves down, gradually pressing the gas in the air cylinder 21-1 into the airbag cover 1 16 and the airbag cover 2 17 for inflation. As it moves down and contacts with the trigger block 24, it is necessary to overcome the action of spring 1 25 on the trigger block 24.

[0053] The deposits on the ring plate 22-4 are increasing. At this time, the ring plate 22-4 moves down less, but the deposits on the ring plate 22-4 are heavier. When the action of the spring 1 25 on the trigger block 24 is overcome, the ring plate 22-4 drops rapidly, and then overcomes the pressure in the air cylinder 21-1, so that the piston 21-2 moves down rapidly to quickly inflate the airbag cover 1 16 and the airbag cover 2 17. At the same time, the deposits on the driving member 22 gradually decrease. Under the action of the pressure in the airbag cover and the air cylinder 21-1, the piston 21-2 and the ring plate 22-4 are reset. In this process, the attachments on the airbag cover 1 16 and the airbag cover 2 17 that are difficult to flush off are removed.

[0054] A post 27 is slidably connected in the limit groove 26, a slot 28 is provided on the trigger block 24, and cooperates with the post 27. An unlocking member 210 is installed in the groove body 29, and cooperates with the post 27. The limit groove 26 is used to limit and guide the post 27 when it moves. Through the setting of the slot 28, after the unlocking member 210 unlocks the support of the post 27, after the trigger block 24 moves the slot 28 to align with the limit groove 26, the post 27 falls into it and clamps the trigger block 24 to limit it. By setting the unlocking member 210, the ring plate 22-4 acts on it when it is not moving downward normally, so that it squeezes the clamping column 27 and moves it upward. After the ring plate 22-4 moves downward and disengages, it loses its support and limit on the clamping column 27, so that the clamping column 27 can move downward to act on the trigger block 24, and when it resets after moving downward, the clamping column 27 is triggered so that the clamping column 27 will not release the limit on the trigger block 24. Only when it resets to act on the unlocking member 210, the clamping column 27 can be separated from the slot 28 and reset under the action of the spring 1 25.

[0055] Example 2

[0056] Reference Figures 2 to 20 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0057] Specifically, the water circulation component 12 includes a filter 121 fixedly connected to the surface of the shell 11. The filter 121 can filter and collect particles in the circulating water. This is a prior art. The working principle of this part is also a prior art. Those skilled in the art can clearly understand it and will not be elaborated here. A water pump 122 is fixedly connected to the top of the filter 121. The input end of the water pump 122 passes through the inner cavity of the filter 121, and the output end of the water pump 122 is connected to a bend pipe 123.

[0058] The top of the inner cavity of the shell 11 is fixedly connected to a ring pipe 124 and a ring pipe 2 125, respectively. The surfaces of the bend pipe 123 and the bend pipe 2 127 are connected with a nozzle 126. One end of the bend pipe 123 is connected to the ring pipe 124 and the ring pipe 2 125 respectively. The bend pipe 2 127 is connected between the bottom of the shell 11 and the filter 121. There are several nozzles 126 on the ring pipe 124 and the ring pipe 2 125. The nozzle 126 on the ring pipe 124 sprays a water curtain on the mesh cover 13, and the nozzle 126 on the ring pipe 2 125 sprays a water curtain on the uppermost airbag cover 16.

[0059] The driving member 22 includes a support plate 22-1 fixedly connected to the bottom of the inner wall of the shell 11, and a vertical rod 22-2 is fixedly connected to the top of the support plate 22-1. A ring 22-3 is sleeved on the surface of the vertical rod 22-2, and a ring plate 22-4 is sleeved on the surface of the ring 22-3. The ring 22-3 is movably sleeved on the surface of the vertical rod 22-2, and the ring 22-3 and the ring plate 22-4 are rotatably connected by a bearing. A guide groove 22-5 is opened on the surface of the vertical rod 22-2, and a ball 22-6 is fixedly connected to the inner wall of the ring 22-3, and is slidably connected in the guide groove 22-5.

[0060] The guide groove 22-5 is divided into two parts. The first part is for the ball 22-6, which will not cause the ring 22-3 to rotate when it moves in it. The second part is for the ball 22-6, which can cause the ring 22-3 to rotate when it moves in it. When the ring plate 22-4 moves downward as the weight of the sediment thereon increases, the ball 22-6 first moves in the first part of the guide groove 22-5, so that the ring 22-3 will not rotate. As the weight of the ring plate 22-4 increases, it overcomes the action of the spring 1 25 on the trigger block 24, causing the ring plate 22-4 to move downward quickly. At this time, the ball 22-6 moves in the second part of the guide groove 22-5, thereby causing the ring 22-3 to rotate. The upper surface of the ring plate 22-4 is annularly inclined, which facilitates the scraper 22-7 to scrape off the sediment thereon when it rotates.

[0061] A scraper 22-7 is fixedly connected to the outer surface of the collar 22-3, and a guide block 22-8 is fixedly connected to the outer surface of the ring plate 22-4. A plurality of scrapers 22-7 are provided on the collar 22-3. Through such a configuration, when the collar 22-3 rotates and drives the scraper 22-7 to rotate, the sediment on the ring plate 22-4 can be scraped, which is convenient for entering the filter 121 for collection along with the circulating water. After weight reduction, the reset operation is performed under the action of the pressure in the air cylinder 21-1. In contrast to the downward movement, a vertical groove 22-9 is provided on the mesh cylinder 14 to cooperate with the guide block 22-8. The guide block 22-8 is slidably connected to the vertical groove 22-9. Through the vertical groove 22-9 and the guide block 22-8, the ring plate 22-4 is guided and limited when moving, so that it will not rotate.

[0062] The inflating and discharging gas component 21 includes an air cylinder 21-1 fixedly connected to the inner wall of the vertical cylinder 15. The air cylinder 21-1 is fixedly connected to the inner wall of the vertical cylinder 15 through a support rod. A piston 21-2 is slidably connected to the inner wall of the air cylinder 21-1. A square rod 21-3 is slidably connected to the air cylinder 21-1, and its upper end is fixedly connected to the bottom of the piston 21-2. The square rod 21-3 passes through the air cylinder 21-1 and is slidably connected to it. The up and down movement of the square rod 21-3 can make the piston 21-2 move up and down, and then the pressure in the air cylinder 21-1 can be injected into the airbag cover 1 16 and the airbag cover 2 17 to make them gradually expand, and the gas in the airbag cover 1 16 and the airbag cover 2 17 can be drawn into the air cylinder 21-1. By changing the volume, the pressure in the airbag cover 1 16 and the airbag cover 2 17 is changed, and then the expansion state is changed.

[0063] A connecting pipe 21-4 is fixedly connected in the net tube 14 and is communicated with the airbag cover 16. A connecting pipe 21-5 is fixedly connected in the vertical tube 15 and is communicated with the airbag cover 2 17. One end of the connecting pipe 21-4 and the connecting pipe 2 21-5 are communicated with a hose 21-6. One end of the hose 21-6 is communicated with the lower end of the air cylinder 21-1. The air cylinder 21-1 is respectively connected with the connecting pipe 1 21-4 and the connecting pipe 2 21-5 through the hose 21-6. When the ring plate 22-4 moves upward, it will not be affected by the obstruction of the hose 21-6. A sealing ring is provided between the square rod 21-3 and the air cylinder 21-1, and is sleeved on the surface of the square rod 21-3 to prevent gas leakage from the gap therebetween. A sealing sleeve is provided between the piston 21-2 and the air cylinder 21-1, and is sleeved on the surface of the piston 21-2 to prevent gas leakage from the gap therebetween.

[0064] The lower end of the square rod 21-3 is fixedly connected to a round block 21-7, and the surface of the round block 21-7 is rotatably connected to a sleeve plate 21-8. A connecting rod 21-9 is fixedly connected between the bottom of the sleeve plate 21-8 and the top of the sleeve ring 22-3. A positioning groove 21-10 is provided on the top of the inner wall of the air cylinder 21-1, and a round hole 21-11 is provided on the top of the air cylinder 21-1. Through the setting of the round hole 21-11, the space formed above the piston 21-2 and the air cylinder 21-1 is connected to the vertical cylinder 15, so that the piston 21-2 reduces obstacles when moving upward, can be reset normally, and can be smoothly moved upward with the help of tools.

[0065] The sleeve plate 21-8 is rotatably connected to the round block 21-7 through a bearing. Through such a connection method, when the sleeve ring 22-3 moves up and down with the ring plate 22-4, the sleeve plate 21-8 can be moved up and down under the action of the connecting rod 21-9, thereby causing the round block 21-7, the square rod 21-3 and the piston 21-2 to move up and down. When the connecting rod 21-9 rotates with the sleeve ring 22-3, the sleeve plate 21-8 can be rotated, but the round block 21-7 and the square rod 21-3 will not be rotated. When the square rod 21-3 and the piston 21-2 move up and down, they are not affected by the rotation of the sleeve ring 22-3, the connecting rod 21-9 and the sleeve plate 21-8.

[0066] Example 3

[0067] Reference Figures 6 to 11 , which is the third embodiment of the present invention, is based on the first two embodiments.

[0068] Specifically, the unlocking member 210 includes an unlocking block 210-1 that is slidably connected to the groove body 29 and cooperates with the card column 27. A slope is set at one end of the unlocking block 210-1. Through such a setting, after the unlocking block 210-1 moves away from the surface of the card column 27, as the trigger block 24 moves, the card column 27 falls into the card slot 28 to limit the trigger block 24. When the card column 27 needs to move up to release the limit on the trigger block 24, the unlocking block 210-1 can move and squeeze the card column 27 to lift it up during the back movement process, thereby disengaging from the card slot 28 on the trigger block 24.

[0069] The groove body 29 is respectively slidably connected with a moving block 210-2, a driving plate 210-3 and a movable plate 210-4. The surface of the moving block 210-2 and the surface of the driving plate 210-3 are in contact and matched with each other. Two inclined surfaces are provided at one end of the moving block 210-2. Through this arrangement, the ring plate 22-4 can squeeze the moving block 210-2 to move into the groove body 29 regardless of moving up and down. The other end of the moving block 210-2 and the upper end of the driving plate 210-3 are both provided with inclined surfaces. Through this arrangement, when the moving block 210-2 moves into the groove body 29, the driving plate 210-3 can move downward to drive the movable plate 210-4 to move downward. When the driving plate 210-3 moves upward, the moving block 210-2 in the groove body 29 can move outward.

[0070] A guide column 210-5 is fixedly connected to the unlocking block 210-1, and the lower end of the driving plate 210-3 is fixedly connected to the top of the movable plate 210-4. A guide hole 210-6 is provided on the movable plate 210-4 to cooperate with the guide column 210-5. The guide column 210-5 is slidably connected in the guide hole 210-6. Through the setting of the guide hole 210-6 and the guide column 210-5, when the movable plate 210-4 moves up and down, it can drive the unlocking block 210-1 to move, so that the unlocking block 210-1 releases the support limit on the card column 27, and supports and limits it again.

[0071] A spring piece 210-7 is fixedly connected between the surface of the movable plate 210-4 and the inner wall of the groove body 29. Through the setting of the spring piece 210-7, a force is provided for resetting the movable plate 210-4 and the drive plate 210-3 after they move downward. The pressure in the air cylinder 21-1 acts on the piston 21-2, overcomes the gravity of the corresponding connection structure, reduces and transforms into an effect on the ring plate 22-4, and can still overcome the effect of the spring piece 210-7 on the moving block 210-2 with the help of the drive plate 210-3, and moves the moving block 210-2 into the groove body 29. When the ring plate 22-4 is separated from the moving block 210-2, the drive plate 210-3 and the movable plate 210-4 are reset up and down under the action of the deformation and reset of the spring piece 210-7.

[0072] A sliding groove 210-8 is provided on the inner wall of the trough body 29, and a slider 210-9 is fixedly connected to the moving block 210-2, and is slidably connected to the sliding groove 210-8. The moving block 210-2 is guided and limited by the slider 210-9 and the sliding groove 210-8 so that it will not separate from the net cylinder 14, and when the moving block 210-2 moves outward, the upper and lower non-inclined surfaces of one end will not move out of the net cylinder 14.

[0073] An air suction hood 19 is connected to the shell 11, a mounting plate 110 is fixedly connected to the top of the shell 11, a water inlet pipe 111 is connected to the side of the shell 11, and a liquid level sensor is installed on the top of the support plate 22-1. By setting the air suction hood 19, the range of air suction of the shell 11 is improved when the fan 18 is running. One end of the water inlet pipe 111 is externally connected to a water supply device and is installed with a solenoid valve, which cooperates with the liquid level sensor to ensure that the water level in the shell 11 is within a certain range and can be replenished in time. This is existing technology, and the working principle of this part is all existing technology. Those skilled in the art can clearly know it and will not be elaborated here.

[0074] An exhaust mechanism 3 is installed on the air filling and discharging part 21. Through the setting of the exhaust mechanism 3, the piston 21-2 in the air cylinder 21-1 is pulled upward, and then the gas in the airbag cover 1 16 and the airbag cover 2 17 is extracted, so that the airbag cover 1 16 and the airbag cover 2 17 are compressed and flattened, and tilted downward to reduce obstruction between them. The mounting plate 110 is removed to facilitate the operator to clean the surface of the airbag cover 1 16 and the airbag cover 2 17 with a long brush.

[0075] Example 4

[0076] Reference Figures 6 to 21 , which is the fourth embodiment of the present invention, and is based on the first three embodiments.

[0077] Specifically, a square groove 211 is provided on the inner wall of the groove 23, and the bottom of the trigger block 24 is fixedly connected to the limiting block 212, and it is slidably connected in the square groove 211. The trigger block 24 is guided and limited by the square groove 211 and the limiting block 212 to prevent the trigger block 24 from detaching from the mesh tube 14 due to the rebound of the spring 25.

[0078] The exhaust mechanism 3 includes a mounting groove 31 provided in the piston 21-2, a pull rod 32 is slidably connected to the air cylinder 21-1, a block 33 is slidably connected to the inner wall of the mounting groove 31, and it cooperates with the positioning groove 21-10, a block 34 is slidably connected in the mounting groove 31, a guide hole 35 is provided on the surface of the block 34, a guide column 36 is fixedly connected to the block 33, and it is slidably connected in the guide hole 35. Through the setting of the guide hole 35 and the guide column 36, when the block 34 moves in the mounting groove 31, the block 33 can be moved, the lower end of the pull rod 32 passes through the piston 21-2 and extends into the mounting groove 31, and is fixedly connected to the top of the block 34, the upper end of the pull rod 32 passes through the air inlet pipe of the fan 18 and extends to the outside thereof.

[0079] By setting the positioning groove 21-10, when the pull rod 32 is pulled up to move the block 34, the contact between the block 33 and the inner wall of the air cylinder 21-1 is hindered, so that the block 33 cannot move in the installation groove 31. Therefore, when the pull rod 32 is pulled up, the piston 21-2 can be moved upward with the help of the block 34, the guide column 1 36 and the block 33, and then the square rod 21-3, the round block 21-7, the sleeve plate 21-8, the connecting rod 21-9 and the ring plate 22-4 are moved upward. The upward movement of the piston 21-2 draws most of the gas in the air bag cover 1 16 and the air bag cover 2 17 into the air cylinder 21-1 through the connecting pipe 1 21-4, the connecting pipe 2 21-5 and the hose 21-6.

[0080] When the piston 21-2 moves up and contacts the top of the inner cavity of the air cylinder 21-1 and cannot move anymore, the block 33 is opposite to the positioning groove 21-10. As the force of the pull rod 32 is applied, the block 34 moves up in the installation groove 31, so that one end of the block 33 is inserted into the positioning groove 21-10 for limiting, so that the airbag cover 1 16 and the airbag cover 2 17 remain in the vacuum vertical head state, reducing the obstruction between each other and facilitating the subsequent cleaning by the operator. When resetting, press the pull rod 32 downward to disengage the block 33 from the positioning groove 21-10, and reset can be performed. A sealing ring is provided between the pull rod 32 and the air inlet pipe of the fan 18, and is sleeved on the surface of the pull rod 32 to prevent gas leakage.

[0081] During use, the operation of the fan 18 and the water circulation component 12 is controlled. The fan 18 draws the dust generated by the grinding of the welding plate and the surrounding gas into the shell 11 through the suction hood 19. The water circulation component 12 sprays the water in the shell 11 from the nozzles 126 on the bend pipe 123 and the ring pipe 124 to form a water curtain, and filters it. Under the action of the deflection water curtains of multiple airbag covers 16 and 17, the dust in the gas is fully settled and then discharged from the air outlet pipe of the fan 18. When the sediment collected on the ring plate 22-4 of the driving part 22 becomes heavier, the inflation and deflation part 21 is acted on, causing the airbag cover 16 and the airbag cover 2 17 to gradually expand and then change slightly, so that the contact points of the particles attached to their surfaces are changed, and they are better separated under the action of hydraulic impact.

[0082] As the ring plate 22-4 on the driving member 22 moves downward and disengages from the moving block 210-2 on the unlocking member 210, the unlocking member 210 releases the limit on the clamping column 27. After the ring plate 22-4 moves downward and contacts the trigger block 24, it needs to overcome the action of spring 1 25 on the trigger block 24. The deposits on the ring plate 22-4 are increasing. At this time, the ring plate 22-4 moves downward less, but the deposits on the ring plate 22-4 are heavier. When the action of spring 1 25 on the trigger block 24 is overcome, the trigger block 24 moves the clamping groove 28 to be aligned with the limiting groove 26, and the clamping column 27 falls into it to clamp the trigger block 24 for limiting. The ring plate 22-4 drops rapidly, thereby overcoming the pressure in the air cylinder 21-1, causing the piston 21-2 to move downward rapidly to quickly inflate the airbag cover 1 16 and the airbag cover 2 17.

[0083] During this process, the ball 22-6 on the collar 22-3 transitions from the first part to the second part on the guide groove 22-5 to move, thereby rotating the collar 22-3 and the scraper 22-7, scraping the sediment on the ring plate 22-4, and facilitating the collection of the circulating water into the filter 121. The sediment on the ring plate 22-4 of the driving member 22 gradually decreases, and under the action of the pressure in the airbag cover and the air cylinder 21-1, the piston 21-2 and the ring plate 22-4 are reset, and the unlocking member 210 supports and lifts the card column 27 again, so that the card column 27 is disengaged from the card slot 28, and the trigger block 24 is reset under the action of spring 1 25.

[0084] In summary, the water curtain dust removal mechanism 1, in cooperation with the adjustment mechanism 2, can reduce the continuous deposition of dust particles on the surface of the air duct. Compared with the existing technology, it ensures the uniformity of the water curtain distribution, reduces the formation of obvious gap areas, and does not require the aid of mechanical cleaning devices for cleaning. During operation, the continuity of the water curtain will not be destroyed and new air flow channels will not be generated, thereby ensuring the dust removal efficiency.

[0085] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
