Description

Technical Field

[0001] The invention relates to the technical field of filtering devices, and in particular to a gas processing device. Background Art

[0002] A compressor is a mechanical device used to compress gas in industrial production. Its main function is to compress low-pressure gas into high-pressure gas to meet the different requirements of gas pressure, flow and purity in the industrial production process. During the operation of the compressor, gas leakage may occur due to equipment failure or improper operation. The leaked gas is usually initially filtered and purified by gas treatment equipment to meet the standards for discharge or reuse, so as to reduce resource waste and environmental impact.

[0003] The gas processing equipment in the prior art, such as a mixed gas automatic filtering device disclosed in the Chinese patent document with the authorization announcement number CN114618255B, is provided with a multi-directional gas outlet mechanism, and the multi-directional gas outlet mechanism is provided with a discharge component with at least two pipelines, which can perform different discharge treatments on the gas. At least two pipelines are provided, one pipeline directly discharges the treated gas, and the other pipeline re-introduces the gas back to the filter chamber for re-filtration. The gas can also be reintroduced into other filtering devices for treatment through other pipelines, so as to avoid the gas being discharged from only one pipeline, and ensure that the gas will not cause damage to the environment when discharged. For the opening and closing of the discharge component, a linkage reciprocating exhaust component is provided. When the discharge component is initially closed, the linkage reciprocating exhaust component is started to control only one pipeline in the discharge component to be open, and the other pipelines remain closed.

[0004] However, after the above-mentioned mixed gas automatic filtering device in the prior art has been working for a period of time, the filter element in the filter chamber is easily blocked by dust and particles carried by the gas, affecting the gas flow rate and filtering effect. Cleaning or replacing the filter element requires temporary shutdown and manual operation, which will cause production interruptions, increase labor costs, and reduce overall efficiency. Summary of the invention

[0005] The present invention provides a gas processing device, aiming to solve the problem that the cleaning of the filter element of the mixed gas automatic filtering device in the related art needs to be temporarily stopped and manually operated, thus affecting the production efficiency.

[0006] The present invention provides a gas processing device adopting the following technical solution:

[0007] A gas processing device comprises a processing tank, an air inlet pipe connected to the left side wall of the processing tank, an air outlet pipe connected to the upper end of the processing tank, and a filter screen arranged in the processing tank, wherein the filter screen is annular and has multiple layers spaced from the inside to the outside, a blocking column is fixed to the lower end of the innermost filter screen, the left cavity in the processing tank forms a filter chamber, the right cavity in the processing tank forms a clean chamber, a cover plate is arranged at the upper end of the multiple layers of the filter screen, the cover plate is provided with a main air vent located in the center of the cover plate, and an auxiliary air vent located in the clean chamber, the main The air vent and the auxiliary air vent are both facing the air outlet pipe. The cleaning chamber is provided with baffles corresponding to each layer of filter screen and mounted on the outside of each layer of filter screen for movement up and down. Each baffle is provided with a sealing plug for blocking the auxiliary air vent. A lifting member is mounted in the processing tank for movement up and down. A transmission groove is provided on the outer peripheral side of the blocking column. A driving block slidingly matched with the transmission groove is provided on the lifting member to drive the blocking column to drive the multiple layers of filter screen to rotate around the central axis of the processing tank. The lower end of each baffle is elastically connected to the lifting member to move up and down with the lifting member.

[0008] By adopting the above technical scheme, a rotatable annular multi-layer filter is arranged in the processing tank, and the processing tank is divided into a filter chamber connected to the air inlet pipe and a cleaning chamber provided with a baffle. The annular multi-layer filter can be driven to rotate by the up and down movement of the lifting member, so that the annular multi-layer filter can rotate and switch between the filter chamber and the cleaning chamber. The up and down movement of the lifting member can also drive the baffle to move up and down, thereby realizing layer-by-layer filtering of the gas through the multi-layer filter in the filter chamber and layer-by-layer cleaning of the multi-layer filter in the cleaning chamber, so that the annular multi-layer filter can work continuously without stopping for filter replacement or cleaning, which can significantly reduce or eliminate the downtime required for filter replacement or cleaning, and the rotation and cleaning of the annular multi-layer filter can be performed automatically, reducing dependence on manual operation and improving production efficiency.

[0009] Furthermore, a dust collecting cavity is formed between the inner wall of each baffle and the filter screen, and the dust collecting cavity gradually expands from the upper end to the lower end.

[0010] The above technical solution is adopted to enable the backblown dust and particles to fall into the collection cup under the action of gravity and the guidance of the inner wall of the baffle, thereby preventing the backblown dust and particles from flowing out from the auxiliary vent with the gas, and at the same time preventing the backblown dust and particles from falling on the filter screen outside the baffle.

[0011] Furthermore, a collecting cup is detachably fixed to the lower end of the processing tank, and the upper end of the collecting cup is communicated with the lower end of the processing tank.

[0012] With the above technical solution, the collection cup is used to collect dust and particles under cleaning.

[0013] Furthermore, there are a plurality of transmission grooves evenly distributed along the circumference of the blocking column, and each transmission groove includes a transmission inclined groove and a reset vertical groove.

[0014] Furthermore, a plurality of guide blades are fixed to the outer peripheral side of the outermost filter, and each of the guide blades is adapted to the rotation direction of the multi-layer filter so as to drive the multi-layer filter to rotate when the guide blades are pushed by the gas of the intake pipe.

[0015] By adopting the above technical solution, the blocking column has a certain rotation tendency, which prevents the driving block from moving down along the reset vertical groove when the liquid storage ring moves down, causing the multi-layer filter to reverse.

[0016] Furthermore, an elastic telescopic rod is arranged between the lower end of each baffle and the lifting member, a boss is fixed to the upper end of the elastic telescopic rod, a fixing rod extending radially along the processing tank is fixed in the processing tank, and a limiting pin corresponding to each baffle and used to limit the downward movement of the boss is arranged on the fixing rod, and the elastic force of the limiting pin gradually increases from the inner layer to the outer layer.

[0017] By adopting the above technical solution, when the lifting part moves up and down, the baffle can be driven to move up and down by the elastic telescopic rod. Since the limit pin limits the downward movement of the baffle by abutting the boss, and the elastic force of the limit pin gradually increases from the inner layer to the outer layer, the innermost baffle will move downward first after cooperating with the corresponding filter to complete the backwash cleaning, so that the baffle of the next layer will cooperate with the corresponding filter for backwash cleaning until all four layers of filter are cleaned, so as to realize the layer-by-layer cleaning of the four layers of filter in the cleaning chamber, ensure the cleaning effect of each layer of filter, remove the dust and blockages on the filter, and thus maintain a high filtration efficiency.

[0018] Furthermore, a cooling mechanism for cooling the gas is provided on the air inlet pipe, the lifting member includes a liquid storage ring and a drain pipe, an annular cavity for installing the liquid storage ring is opened at the lower end of the processing tank, the left end of the annular cavity is connected with the air inlet pipe to guide the condensed water in the air inlet pipe into the liquid storage ring, and the drain pipe is arranged at the lower end of the liquid storage ring and connected with the outside.

[0019] By adopting the above technical solution, the leaked high-temperature gas is cooled and then filtered, which can reduce the thermal stress on the filter, thereby extending the service life of the filter and improving the filtration efficiency; the condensed water generated during the gas cooling process is collected and discharged, and the gravity of the condensed water generated during continuous ventilation is used to drive the lifting parts up and down. No additional energy input is required, which can reduce energy consumption, improve resource utilization, and comply with the concept of energy conservation and environmental protection.

[0020] Furthermore, the lifting member also includes a connecting rod, a handle and a return spring. The connecting rod is fixed to the inner circumference of the liquid storage ring and abuts against the side wall of the blocking column. The handle is fixed to the lower end of the connecting rod and passes downward through the collecting cup. The return spring is connected between the liquid storage ring and the collecting cup.

[0021] Furthermore, the drain pipe is assembled on the lower end of the liquid storage ring so as to move up and down, a sealing head located inside the liquid storage ring is fixed on the upper end of the drain pipe, a first spring is arranged between the sealing head and the liquid storage ring, a water hole is provided on the drain pipe below the sealing head, a sealing sleeve capable of sealing the water hole is assembled on the outside of the drain pipe so as to move up and down, and a second spring is arranged between the sealing sleeve and the collection cup.

[0022] Furthermore, a delay ball capable of abutting against the lower end of the blocking column is arranged on the inner side of the handle.

[0023] By adopting the above technical solution, when the liquid storage ring moves down to the lowest position, the delay ball abuts against the lower end of the blocking column to limit the upward movement of the lifting part. The setting of the delay ball can give the liquid storage ring a certain drainage time to ensure that the liquid in the liquid storage ring can be completely discharged, thereby avoiding the liquid in the liquid storage ring from moving up and resetting under the action of the elastic force of the reset spring before the liquid in the liquid storage ring is completely discharged.

[0024] The beneficial effects of a gas processing equipment provided by the present invention are as follows: a rotatable annular multi-layer filter is arranged in a processing tank, and the processing tank is divided into a filter chamber connected to the air inlet pipe and a cleaning chamber provided with a baffle; the annular multi-layer filter can be driven to rotate by the up and down movement of the lifting member, so that the annular multi-layer filter can rotate and switch between the filter chamber and the cleaning chamber; the up and down movement of the lifting member can also drive the baffle to move up and down, thereby achieving layer-by-layer filtering of the gas through the multi-layer filter in the filter chamber, and layer-by-layer cleaning of the multi-layer filter in the cleaning chamber, so that the annular multi-layer filter can work continuously without stopping for filter replacement or cleaning, which can significantly reduce or eliminate the downtime required for filter replacement or cleaning, and the rotation and cleaning of the annular multi-layer filter can be performed automatically, reducing dependence on manual operation and improving production efficiency.

DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figures 1 to 6 As shown, and refer to Figure 2 As shown in the figure, an embodiment of the gas processing equipment of the present invention is used to filter and process the gas leaked from the compressor, and includes an air inlet pipe 10, a cooling mechanism 110, a processing tank 20, a cover plate 30, a filter screen 40, a baffle plate 50, a blocking column 60, a lifting member 70, a collecting cup 80, and an air outlet pipe 90. The air inlet pipe 10 and the air outlet pipe 90 are respectively arranged outside the processing tank 20, the collecting cup 80 is installed below the processing tank 20, the cooling mechanism 110 is arranged on the air inlet pipe 10, and the cover plate 30, the filter screen 40, the baffle plate 50, the blocking column 60, and the lifting member 70 are respectively arranged inside the processing tank 20.

[0035] like Figure 1 and Figure 2As shown, the air inlet pipe 10 is connected to the left side wall of the treatment tank 20, and is used to introduce the gas leaked from the compressor into the treatment tank 20. The cooling mechanism 110 is an air cooler, and is arranged on the air inlet pipe 10, and is used to cool the gas leaked from the compressor. In other embodiments, the cooling mechanism 110 can also be a water cooler. During the operation of the compressor, the gas is compressed, and its temperature will increase due to the compression process. The high-temperature gas may accelerate the wear and aging of the filter 40 material. Cooling and cooling the leaked high-temperature gas before filtering can reduce the thermal stress on the filter 40, thereby extending the service life of the filter 40 and improving the filtering efficiency.

[0036] like Figure 1 and Figure 2 As shown, the gas outlet pipe 90 is connected to the upper end of the processing tank 20 and is used to discharge the filtered gas in the processing tank 20.

[0037] like Figure 2 As shown, the left cavity in the treatment tank 20 forms a filtering chamber for filtering the gas through the filter screen 40; the right cavity in the treatment tank 20 forms a cleaning chamber for cleaning the filter screen 40 after filtering. The collection cup 80 is detachably fixed to the lower end of the treatment tank 20, and the upper end of the collection cup 80 is connected to the lower end of the treatment tank 20 for collecting dust and particles under cleaning. The collection cup 80 in the embodiment is installed at the lower end of the treatment tank 20 by threaded connection. In other embodiments, a detachable assembly method such as magnetic connection, snap connection, bolt connection, etc. can also be adopted.

[0038] like Figures 2 to 4 As shown, the filter screen 40 is arranged in the treatment tank 20. The filter screen 40 is annular and has four layers spaced from the inside to the outside. The aperture of the filter screen 40 gradually decreases from the outer layer to the inner layer. The four layers of filter screens 40 are fixedly connected by connecting rods 420, and the four layers of filter screens 40 can rotate around the central axis of the treatment tank 20. The blocking column 60 is fixed to the lower end of the innermost filter screen 40, and is used to block the lower end opening of the innermost filter screen 40. The lower end of the blocking column 60 is rotatably connected to the collection cup 80. The cover plate 30 is fixed in the treatment tank 20 and is located at the upper end of the four layers of filter screens 40. The cover plate 30 is provided with a main vent 310 located in the center of the cover plate 30 and an auxiliary vent 320 located in the cleaning chamber. The main vent 310 and the auxiliary vent 320 are both facing the outlet pipe 90. The processing tank 20 in the embodiment is provided with a semi-annular sealing plate 230 in the filter chamber, the outer end of the sealing plate 230 is fixed to the inner wall of the processing tank 20, the inner end of the sealing plate 230 is in contact with the outer wall of the blocking column 60, and the upper surface of the sealing plate 230 is in contact with the lower surface of the four-layer filter screen 40, which is used to prevent the gas from overflowing outward from the lower end of the four-layer filter screen 40 and ensure the filtering effect of the gas.

[0039] Therefore, after the gas leaked from the compressor enters the treatment tank 20 from the air intake pipe 10 located on the left side of the treatment tank 20, it is filtered layer by layer through the four layers of filter screens 40 in the filter chamber. The setting of the four layers of filter screens 40 can perform graded filtration according to the particle size. Each layer of filter screens 40 intercepts particles of different sizes, thereby improving the overall filtration efficiency and ensuring the quality of the final gas. Moreover, since each layer of filter screens 40 is only responsible for intercepting particles of a specific size, the load of each layer of filter screens 40 is relatively small, which can extend the service life of the filter screens 40 and reduce the risk of clogging of the filter screens 40. When the auxiliary air vent 320 is closed, the gas filtered in the filter chamber enters the outlet pipe 90 through the main air vent 310 and is discharged through the outlet pipe 90; when the auxiliary air vent 320 is opened, the gas filtered in the filter chamber can back-blow and clean the four-layer filter 40 rotated to the cleaning chamber, and then enter the outlet pipe 90 through the auxiliary air vent 320 to be discharged; so as to realize the continuous operation of the annular multi-layer filter 40 without stopping the machine for replacing or cleaning the filter 40, which can significantly reduce or eliminate the downtime required for replacing or cleaning the filter 40, and the rotation and cleaning of the annular multi-layer filter 40 can be performed automatically, reducing the dependence on manual operation and improving production efficiency.

[0040] like Figures 2 to 4 As shown, the baffles 50 correspond to each layer of the filter screen 40 and are arranged in the cleaning chamber. Each baffle 50 moves up and down and is assembled on the outer side of the corresponding filter screen 40. A dust collecting cavity 520 is formed between the inner wall of each baffle 50 and the corresponding filter screen 40. The dust collecting cavity 520 gradually expands from the upper end to the lower end, so that the dust and particles blown back can fall into the collection cup 80 under the action of gravity and the guidance of the inner wall of the baffle 50, so as to prevent the dust and particles blown back from flowing out from the auxiliary vent 320 with the gas, and at the same time, it can prevent the dust and particles blown back from falling on the filter screen 40 outside the baffle 50. A sealing plug 510 for sealing the auxiliary air vent 320 is provided on each baffle 50. The baffle 50 can be moved upward until the sealing plug 510 is inserted into the auxiliary air vent 320 so that the sealing plug 510 seals the auxiliary air vent 320, thereby controlling the gas flow direction, and can be moved downward until the sealing plug 510 is disengaged from the auxiliary air vent 320, opening the auxiliary air vent 320 to enter a cleaning state for the filter 40.

[0041] like Figure 2 , Figure 3 and Figure 5 As shown, the lifting member 70 moves up and down and is assembled in the collection cup 80. The lifting member 70 includes a liquid storage ring 710, a connecting rod 720, a handle 730, a return spring 740, a drain pipe 750, and a driving block.

[0042] like Figure 2As shown, the liquid storage ring 710 has a liquid storage cavity with an opening facing upward, and an annular cavity 220 for installing the liquid storage ring 710 is opened at the lower end of the processing tank 20. The liquid storage ring 710 is assembled in the annular cavity 220 for moving up and down. The left end of the annular cavity 220 is connected to the air inlet pipe 10 to guide the condensed water in the air inlet pipe 10 into the liquid storage cavity of the liquid storage ring 710, so as to collect and discharge the condensed water generated in the gas cooling process, and utilize the gravity of the condensed water generated in the continuous ventilation process to drive the lifting member 70 to move up and down. No additional energy input is required, which can reduce energy consumption, improve resource utilization, and comply with the concept of energy conservation and environmental protection.

[0043] like Figure 3 As shown, two connecting rods 720 are symmetrically arranged and respectively fixed to the inner circumference of the liquid storage ring 710. One end of each connecting rod 720 away from the liquid storage ring 710 abuts against the side wall of the blocking column 60 to support the liquid storage ring 710, thereby improving the stability of the liquid storage ring 710 when moving up and down. The handle 730 corresponds to each connecting rod 720 and is fixed to the lower end of the connecting rod 720. Each handle 730 passes through the collection cup 80 downward. The reset spring 740 is connected between the liquid storage ring 710 and the collection cup 80 to apply an upward elastic force to the liquid storage ring 710 so that the liquid storage ring 710 can move up and reset. The drive block is fixed to the side wall of the connecting rod 720 facing the blocking column 60.

[0044] like Figure 5 As shown, a transmission groove 610 is opened on the outer peripheral side of the blocking column 60, and multiple transmission grooves 610 are evenly distributed along the circumference of the blocking column 60 and connected end to end. Each transmission groove 610 includes a transmission inclined groove 611 and a reset vertical groove 612. The driving block is slidably assembled in the transmission groove 610 to drive the blocking column 60 to drive the multi-layer filter screen 40 to rotate around the central axis of the processing tank 20.

[0045] like Figure 2 and Figure 6 As shown, the drain pipe 750 is arranged at the lower end of the liquid storage ring 710 and is connected to the outside. The drain pipe 750 is assembled at the lower end of the liquid storage ring 710 so as to move up and down. A plugging head 751 located in the liquid storage ring 710 is fixed at the upper end of the drain pipe 750. A first spring 752 is arranged between the plugging head 751 and the liquid storage ring 710 to apply a downward elastic force to the plugging head 751 and the drain pipe 750 so as to enable the plugging head 751 and the drain pipe 750 to move downward and reset. The drain pipe 750 is provided with a water hole 753 below the plugging head 751. A sealing sleeve 754 capable of blocking the water hole 753 is assembled outside the drain pipe 750 so as to move up and down. A second spring 755 is arranged between the sealing sleeve 754 and the collection cup 80 so as to apply an upward elastic force to the sealing sleeve 754 so as to enable the sealing sleeve 754 to move upward and block the water hole 753.

[0046] Therefore, when there is no condensed water in the liquid storage ring 710, under the action of the reset spring 740, the liquid storage ring 710 moves up and resets. At this time, the water hole 753 of the drain pipe 750 is below the outside of the liquid storage ring 710, and the liquid storage ring 710 can store liquid; as the condensed water entering the liquid storage ring 710 gradually increases, the liquid storage ring 710 moves downward under the action of gravity, and the driving block moves along the transmission inclined groove 611, and pushes the blocking column 60 to drive the multi-layer filter screen 40 to rotate a certain angle around the central axis of the processing tank 20; until the liquid storage ring 710 moves down to the lowest position, The water hole 753 of the drain pipe 750 extends into the liquid storage ring 710, and the liquid in the liquid storage ring 710 enters the drain pipe 750 through the water hole 753, and is then discharged to the outside. At this time, under the action of the reset spring 740, the liquid storage ring 710 moves up and resets, and the drive block moves up and resets along the reset vertical groove 612; the next time the liquid storage ring 710 stores and discharges condensed water, the drive block continues to move along the next transmission groove 610, and drives the multi-layer filter screen 40 to continue to rotate a certain angle, so that the multi-layer filter screen 40 can rotate and switch between the filter chamber and the cleaning chamber.

[0047] like Figure 4 As shown, a plurality of guide blades 410 are fixed on the outer peripheral side of the outermost filter 40, and each guide blade 410 is adapted to the rotation direction of the multi-layer filter 40, so that when the guide blades 410 are pushed by the gas of the intake pipe 10, the multi-layer filter 40 and the blocking column 60 are driven to rotate, so that the blocking column 60 has a certain rotation tendency, thereby preventing the driving block from moving downward along the reset vertical groove 612 when the liquid storage ring 710 moves downward, causing the multi-layer filter 40 to reverse.

[0048] like Figure 3 and Figure 5As shown, the inner side of the handle 730 is provided with a delay ball 731 that can abut against the lower end of the blocking column 60. Specifically, the delay ball 731 includes a delay slider and a delay spring. The inner side of the handle 730 is provided with a ball groove for accommodating the delay slider, and the delay slider is elastically connected to the ball groove through the delay spring. When the liquid storage ring 710 moves down to the lowest position, the delay ball 731 abuts against the lower end of the blocking column 60 to limit the upward movement of the lifting member 70. At this time, the elastic force of the reset spring 740 is less than the sum of the elastic force of the delay ball 731 and the gravity of the liquid storage ring 710. The liquid storage ring 710 can discharge normally until the discharge is completed. The reset spring 740 can overcome the sum of the elastic force of the delay ball 731 and the gravity of the liquid storage ring 710, and then drive the liquid storage ring 710 to move up and reset. The setting of the delay ball 731 can give the liquid storage ring 710 a certain amount of drainage time to ensure that the liquid in the liquid storage ring 710 can be completely discharged, and avoid the liquid in the liquid storage ring 710 being moved up and reset under the elastic force of the reset spring 740 before the liquid in the liquid storage ring 710 is completely discharged. It should be noted that the setting of the handle 730 is a backup method, so that when the liquid storage ring 710 cannot be driven up and down by the gravity of the condensed water, the handle 730 can be manually pulled to drive the liquid storage ring 710 to move up and down, and then drive the multi-layer filter 40 to rotate.

[0049] like Figure 3 and Figure 5 As shown, an elastic telescopic rod 530 is arranged between the lower end of each baffle 50 and the lifting member 70, a boss 531 is fixed to the upper end of the elastic telescopic rod 530, a fixing rod 210 extending radially along the processing tank 20 is fixed in the processing tank 20, and a limiting pin 211 corresponding to each baffle 50 and used to limit the downward movement of the boss 531 is arranged on the fixing rod 210, and the elastic force of the limiting pin 211 gradually increases from the inner layer to the outer layer.

[0050] Therefore, when the lifting member 70 moves up and down, the baffle 50 can be driven to move up and down through the elastic telescopic rod 530, and since the limiting pin 211 limits the downward movement of the baffle 50 by abutting against the boss 531, and the elastic force of the limiting pin 211 gradually increases from the inner layer to the outer layer, then the innermost baffle 50 cooperates with the corresponding filter 40 to complete the backwash cleaning, and will first move downward to allow the baffle 50 of the next layer to cooperate with the corresponding filter 40 for backwash cleaning until all four layers of filter 40 are cleaned, so as to achieve layer-by-layer cleaning of the four layers of filter 40 in the cleaning chamber, ensure the cleaning effect of each layer of filter 40, remove dust and blockages on the filter 40, and maintain a higher filtration efficiency.

[0051] It should be noted that in this embodiment, the outermost baffle 50 is fixed in the clean chamber, does not move up and down with the lifting member 70, and no sealing plug 510 is provided on the outermost baffle 50. In other embodiments of the gas treatment device of the present invention, the outermost baffle 50 can also be moved up and down like other baffles 50 and assembled in the clean chamber, and a sealing plug 510 is provided.

[0052] The working process of the embodiment of the gas processing equipment of the present invention comprises the following steps:

[0053] The first step is ventilation, in which the gas leaked from the compressor is introduced into the air inlet pipe 10 , and the cooling mechanism 110 cools the gas leaked from the compressor. The condensed water generated during the cooling process enters the liquid storage cavity of the liquid storage ring 710 through the annular cavity 220 .

[0054] The second step is rotation. As the amount of condensed water entering the liquid storage ring 710 gradually increases, the liquid storage ring 710 moves downward under the action of gravity, the driving block moves along the transmission inclined groove 611, and pushes the blocking column 60 to drive the multi-layer filter screen 40 to rotate a certain angle around the central axis of the treatment tank 20; until the liquid storage ring 710 moves down to the lowest position, the water hole 753 of the drain pipe 750 extends into the liquid storage ring 710, and the liquid in the liquid storage ring 710 enters the drain pipe 750 through the water hole 753, and then is discharged to the outside. At this time, under the action of the reset spring 740, the liquid storage ring 710 moves up and resets, and the driving block moves up and resets along the reset vertical groove 612; the next time the liquid storage ring 710 stores and discharges condensed water, the driving block continues to move along the next transmission groove 610, and drives the multi-layer filter screen 40 to continue to rotate a certain angle, so that the multi-layer filter screen 40 rotates and switches between the filter chamber and the cleaning chamber.

[0055] The third step is filtering. The cooled gas enters the processing tank 20 from the air inlet pipe 10 and is filtered layer by layer through the four-layer filter screen 40 in the filter chamber. The filtered gas enters the air outlet pipe 90 through the main air vent 310 and is discharged through the air outlet pipe 90.

[0056] The fourth step is cleaning. When the lifting member 70 moves up and down, the baffle 50 is driven to move up and down by the elastic telescopic rod 530. When the baffle 50 moves down from the highest position, the sealing plug 510 is separated from the auxiliary vent 320, and the auxiliary vent 320 is opened, and the filter 40 is cleaned. The gas filtered in the filter chamber back-blows the innermost filter 40 that rotates to the cleaning chamber, and then enters the outlet pipe 90 through the auxiliary vent 320 for discharge. The dust and particles blown back are discharged in Under the action of gravity and the guidance of the inner wall of the baffle 50, it falls into the collection cup 80; when the baffle 50 continues to move downward, the limiting pin 211 limits the downward movement of the baffle 50 by abutting against the boss 531, and the elastic force of the limiting pin 211 gradually increases from the inner layer to the outer layer. Then, after the innermost baffle 50 cooperates with the corresponding filter 40 to complete the backwash cleaning, it will move downward first, so that the baffle 50 of the next layer cooperates with the corresponding filter 40 for backwash cleaning, until all four layers of filter 40 are cleaned.

[0057] In this way, a rotatable annular multi-layer filter 40 is arranged in the processing tank 20, and the processing tank 20 is divided into a filter chamber connected to the air inlet pipe 10 and a cleaning chamber provided with a baffle 50. The up and down movement of the lifting member 70 can drive the annular multi-layer filter 40 to rotate, so that the annular multi-layer filter 40 can rotate and switch between the filter chamber and the cleaning chamber. The up and down movement of the lifting member 70 can also drive the baffle 50 to move up and down, thereby realizing layer-by-layer filtering of the gas through the multi-layer filter 40 in the filter chamber, and layer-by-layer cleaning of the multi-layer filter 40 in the cleaning chamber, so that the annular multi-layer filter 40 can work continuously without stopping for replacement or cleaning of the filter 40, which can significantly reduce or eliminate the downtime required for replacement or cleaning of the filter 40, and the rotation and cleaning of the annular multi-layer filter 40 can be performed automatically, reducing the dependence on manual operation and improving production efficiency.
