Description

Technical Field

[0001] The present invention relates to the field of air pollution control, and in particular to a purification device and method for air pollution control. Background Art

[0002] Many of the current methods for air pollution control are to use a multi-stage filtration system, which sends polluted air into the filtration system, and intercepts the pollutant particles in the air through the filter layer to achieve a purification effect. The filter layer is generally set in the form of a detachable filter element. After a period of use, pollutants will remain in the filter element. Continuing to use it will affect the filtration and purification of the air. Therefore, it is necessary to replace the old filter element to allow the filtration system to maintain its purification ability.

[0003] When replacing the filter element of the purification equipment, you need to open the equipment, take out the old filter element, put in the new filter element, and close the equipment. The whole process is manual assembly and disassembly, which is troublesome. In addition, due to the proficiency of the replacement operation and the structural size of the filter element, the equipment is in an open state for a long time during replacement, which makes it easy for dust to fall into the equipment, causing internal pollution and affecting the purification effect.

[0004] Therefore, in order to solve the above problems, a purification device can be designed that facilitates the automatic replacement of filter elements, so that the old filter element can be removed and the new filter element can be inserted simultaneously, reducing the time of opening the internal space when the equipment replaces the filter element and reducing the entry of dust and pollutants.

[0015] A purification method for air pollution control, using the above-mentioned purification equipment for air pollution control, comprises the following steps: S1: The user places the new filter element stably at the starting end N1 of the tunnel, and makes it close to the support plate and the auxiliary push plate; S2: The user starts the motor to control the rotation of the driving gear. Through the meshing transmission, the driving gear outputs power to the driven gear. The driven gear drives the stud to rotate together, and drives the No. 1 screw sleeve connected to the stud thread to move upward along the stud. With the help of the synchronously moving upward material change plate, the old filter element originally at the M1 position in the replacement bin is gradually pushed into the tunnel along the h1 direction. Under the pushing action of the old filter element, the closing plate overcomes the elastic force of the No. 1 reset spring, moves upward along the guide column, opens the No. 1 channel, and the old filter element enters the tunnel near the N2 position through the No. 1 channel. S3: Simultaneously with S2, the rotating stud and linkage gear transmit power to the first input bevel gear through the meshing transmission of the first input spur gear, the first transmission main spur gear, the first transmission sub-spur gear and the first linkage main spur gear in sequence, and transmit power to the screw rod again according to the meshing transmission of the first output bevel gear, the first linkage sub-spur gear and the first output spur gear in sequence, and the rotating screw rod controls the No. 2 screw sleeve to move from the starting end of the tunnel into the tunnel, and the new filter element is pushed into the tunnel along the h2 direction with the help of the synchronously moving support plate, gradually approaching the N2 position; S4: At the same time as S2 and S3, the lifting plate cooperates with the top plate in the process of moving upward to continuously compress the upper gas hood, so that the gas in the upper gas hood flows into the gas cylinder through the No. 1 gas pipe. The gas pressure causes the plunger to move in the gas cylinder, causing the push piece to continuously move toward the side of the storage bin and away from the No. 2 door panel; S5: Simultaneously with S2, S3 and S4, the linkage gear transmits power to the second input spur gear meshing with it, and sequentially controls the rotation of the ring gear through the meshing transmission of the second input bevel gear, the second output bevel gear and the second output spur gear, driving the sealing plate fixed to the ring gear to rotate, gradually blocking and closing the opening, and transmits power to the third input spur gear through the rotation of the ring gear, and sequentially controls the rotation of the receiving gear through the meshing transmission of the third input bevel gear, the third output bevel gear, the third transmission bevel gear, the third linkage bevel gear and the third linkage spur gear, driving the rotation of the ball valve fixed to the receiving gear, and gradually opening the air outlet; S6: When the new filter element moves to the inlet position, the No. 1 door panel automatically flips open due to the push force of the new filter element, and the sealing plate just completely blocks and closes the opening, and the ball valve just opens the air outlet. At this time, the tension sensor detects that the tension value of the tension spring reaches F1, and sends a signal to the fan, which starts the fan. At the same time, the air inlet valve is closed, and the conversion valve is opened. Clean air flows into the purification tank through the outlet pipe, the connecting pipe and the air inlet pipe in turn. Because the sealing plate closes the opening, the air cannot pass through the partition and can only flow into the air supply pipe from the opened air outlet, and finally discharged from the air outlet nozzle, forming a wind curtain at the inlet position. In the process of the new filter element pushing the No. 1 door panel and entering the tunnel, dust is prevented from entering the tunnel through the opened inlet, and the surface of the new filter element is blown by wind at the same time; S7: The old filter element and the new filter element continue to move in the predetermined direction. When the new filter element completely enters the tunnel and arrives near the No. 1 channel, the No. 1 door panel automatically falls back and recloses the inlet. At this time, the old filter element is completely pushed into the tunnel and reaches the N2 position. According to S4 and S5, the push piece is also completely retracted into the storage bin, the sealing plate reopens the passage, the ball valve closes the air outlet again, and the tension sensor detects that the tension value of the tension spring reaches F2, sending a signal to the fan, the fan stops running, and the air inlet valve reopens and the conversion valve closes again; S8: At the same time as S7, the tension sensor sends a signal to the air pump, which inflates the airbag to expand it, overcomes the elastic force of the No. 2 return spring, and pushes the auxiliary push rod out of the connecting frame. When the support plate does not move, the auxiliary push plate pushes the new filter element to the N2 position, and gradually pushes the old filter element in the N2 area to the M2 position, and the new filter element replaces the old filter element and enters the N2 position; S9: Then, the motor outputs power in the reverse direction. According to the power transmission relationship in S2-S7, the closing plate and the material replacement plate drive the new filter element to move along the h3 direction from the N2 position to the M1 position, and the support plate also gradually moves back to the starting position of the tunnel along the h4 direction. At the same time, the lifting plate compresses the lower air hood, and the gas in the lower air hood flows into the air cylinder through the No. 2 air pipe, causing the plunger to move in the opposite direction in the air cylinder, causing the push plate to generate a push force on the old filter element at the M2 position at this time, and the movement of the old filter element overcomes the elastic force of the No. 3 reset spring, and the No. 2 door plate is pushed open from the warehouse outlet; S10: When the support plate passes through the No. 1 door panel, according to S6 and S7, the air outlet forms an air curtain at the opened inlet again. When the new filter element completely enters the M1 position, the entire replacement process is completed. The old filter element is finally completely exposed outside the tunnel and is taken away manually. After being taken away, the No. 2 door panel closes the outlet again under the recovery action of the elastic force of the No. 3 reset spring.

[0016] Beneficial effects of the present invention: 1. By setting a closed chamber assembly on the top of the purification tank and cooperating with the synchronous output power of the lifting assembly and the pushing assembly, the filter element can be replaced in a closed space. Compared with the traditional method of replacing the filter element, the internal space of the purification tank and the replacement chamber will not be exposed to the environment for a long time and cause contamination; 2. When a new filter element is put in, an air curtain can be formed at the tunnel entrance to prevent dust from entering the tunnel through the open door No. 1, making the tunnel less likely to be polluted; 3. The wind curtain can not only block the dust from entering, but also play the role of blowing and cleaning the surface of the new filter element, removing a small amount of dust on the surface of the filter element; 4. The fan in the purification tank is used as the power source for the air curtain, and no additional electromechanical equipment is required, so the overall manufacturing cost and operating cost are lower; 5. By using the opening and closing rotation of the intake valve and the conversion valve, the intake channel can be adjusted during the replacement of the filter element, and the purified air can be used as the air source output by the air curtain, which contains less pollutants; 6. The fan will only start when the sealing plate closes the opening to prevent the fan from continuing to run during the filter element replacement, causing a large amount of polluted air to flow into the replacement chamber.

When the support plate 802 pushes the new filter element to a position close to the old filter element that has been lifted into the tunnel 301, the tension sensor 1403 detects that the tension value of the tension spring 1402 reaches F2, and sends a signal to the air pump 804. The air pump 804 inflates the airbag 805. The expanded airbag 805 pushes the auxiliary push rod 806 out of the connecting frame 803 (overcoming the elastic force of the second return spring 808), and the auxiliary push plate 806 is pushed out of the connecting frame 803. 07 Push the new filter element to the N2 position, and push the old filter element at this position to the M2 position.

After the new filter element enters the N2 position, the pump stops inflating the airbag 805. After the airbag 805 shrinks, under the action of the No. 2 return spring 808, the auxiliary push rod 806 retracts into the connecting frame 803 (in actual applications, another sensor can be set on the No. 2 return spring 808 to detect the position of the new filter element).

The second door plate 1103 is used to open or close the warehouse outlet. When the motor 401 outputs power in the reverse direction to control the lifting component to move in the h3 direction and the pushing component to move in the h4 direction, the lifting plate 502 compresses the lower air hood 903, so that the gas in the lower air hood 903 flows into the air cylinder 1002 through the second air pipe 904. Under the action of the increasing air pressure, the plunger 1003 extends out of the air cylinder 1002 and pushes the old filter element at the M2 position through the push piece 1004 (the lifting component moves in the h1 direction, and the pushing component moves in the h3 direction, the lifting plate 502 compresses the upper air hood 901, and the upper air hood The gas in 901 flows into the gas cylinder 1002 through the No. 1 gas pipe 902, causing the plunger 1003 and the push piece 1004 to move toward the side of the storage bin 1001. When the new filter element enters the N2 position, the push piece 1004 is in a state of being completely retracted into the storage bin 1001).

Through the transmission of the linkage gear 405, the second input spur gear 1301 meshed with it transmits power to the second connecting rod 1302, the second input bevel gear 1303, the second output bevel gear 1304 and the second output spur gear 1 305, controls the gear ring 1204 meshing with the second output flat gear 1305 to rotate, which also causes the sealing plate 1203 to rotate. The sealing plate 1203 experiences two states of closing and opening the opening 1202 during the rotation. When the opening 1202 is closed, the air entering the purification tank 101 through the air inlet pipe 1701 will not flow to the replacement chamber 102 through the partition 1201. When the opening 1202 is opened, the air entering the purification tank 101 through the air inlet pipe 1701 flows to the replacement chamber 102 and the air outlet pipe 1703 through the partition 1201 (when the push assembly moves to open the No. 1 door panel 306, the opening 1202 is in a state of being blocked and closed by the sealing plate 1203. At other times, the opening 1202 is closed. At the same time, the rotation of the gear ring 1204 also outputs power to the third input bevel gear 1602, the third output bevel gear 1603, the third connecting rod 1604, the third transmission bevel gear 1605, the third linkage bevel gear 1606 and the third linkage flat gear 1607 in sequence through the third input flat gear 1601. When the third linkage flat gear 1607 drives the receiving gear 1503 to rotate, the ball valve 1502 rotates accordingly to open or close the air outlet 1501 (when the push assembly moves to cause the No. 1 door panel 306 to open, the air outlet 1501 is in the open state, and at other times, the air outlet 1202 is in the closed state). The push assembly moves to the No. 1 door panel 306. 6, the lifting plate 502 is also at the corresponding height, so that the tension spring 1402 generates the corresponding tension value F1. At this time, the tension sensor 1403 sends a signal to the fan 105, and at the same time sends a signal to the air inlet valve 1702 and the conversion valve 1705. The air inlet valve 1702 is closed, and the conversion valve 1705 is opened. After the fan 105 is running, the clean gas in the purification room on the side of the air inlet 103 enters the purification tank 101 through the connecting pipe 1704 under the suction action of the fan 105. Because the port 1202 is closed at this time, the gas can only enter the air delivery pipe 1504 through the air outlet 1501 and be discharged from the air outlet 1505, forming a wind curtain at the warehouse entrance to prevent dust from entering the tunnel 301.

[0027] See also Figure 1-Figure 16In this embodiment, the present invention provides a purification method for air pollution control, using an air pollution control purification device as described above, comprising the following steps: S1: The user places the new filter element stably at the starting end N1 of the tunnel 301 and makes it close to the support plate 802 and the auxiliary push plate 807; S2: The user starts the motor 401 to control the driving gear 402 to rotate. Through the meshing transmission, the driving gear 402 outputs power to the driven gear 403. The driven gear 403 drives the stud 404 to rotate together, and drives the No. 1 screw sleeve 501 threadedly connected to the stud 404 to move upward along the stud 404. With the help of the synchronously moving upward material replacement plate 504, the old filter element originally at the M1 position in the replacement bin 102 is gradually pushed into the tunnel 301 along the h1 direction. Under the pushing action of the old filter element, the closing plate 303 overcomes the elastic force of the No. 1 return spring 304, moves upward along the guide column 302, opens the No. 1 channel opening, and the old filter element enters the tunnel 301 near the N2 position through the No. 1 channel opening; S3: Simultaneously with S2, the rotating stud 404 and the linkage gear 405 transmit power to the first input bevel gear 606 through the meshing transmission of the first input flat gear 601, the first transmission main flat gear 602, the first transmission sub-flat gear 603 and the first linkage main flat gear 604 in sequence, and transmit power to the screw 704 again according to the meshing transmission of the first output bevel gear 702, the first linkage sub-flat gear 701 and the first output flat gear 703 in sequence, and the rotating screw 704 controls the second screw sleeve 801 to move from the starting end of the tunnel 301 into the tunnel 301, and the new filter element is pushed into the tunnel 301 along the h2 direction with the help of the synchronously moving support plate 802, gradually approaching the N2 position; S4: At the same time as S2 and S3, the lifting plate 502 cooperates with the top plate 202 in the process of moving upward to continuously compress the upper gas cover 901, so that the gas in the upper gas cover 901 flows into the gas cylinder 1002 through the No. 1 gas pipe 902, and the gas pressure causes the plunger 1003 to move in the gas cylinder 1002, so that the push piece 1004 continuously moves toward the side of the storage bin 1001 and away from the No. 2 door plate 1103 (the No. 1 gas pipe 902 and the No. 2 gas pipe 904 are respectively connected to the two ends of the gas cylinder 1002, and the inflow of gas forms pressures in two opposite directions, causing the plunger 1003 to move in different directions); S5: At the same time as S2, S3 and S4, the linkage gear 405 transmits power to the second input spur gear 1301 meshing with it, and sequentially controls the gear ring 1204 to rotate through the meshing transmission of the second input bevel gear 1303, the second output bevel gear 1304 and the second output spur gear 1305, driving the sealing plate 1203 fixed to the gear ring 1204 to rotate, gradually blocking and closing the opening 1202 (it is worth noting that the sealing plate 1203 and the opening 1202 can be designed as a fan-shaped structure, the size of the sealing plate 1203 is larger than the size of the opening 1202, and the opening 1202 is not opened or closed at a time point, but a time period. When the sealing plate 1203 rotates to the opening 1202, it is closed. When it continues to rotate, because the sealing plate 1203 is large in size, the opening 1202 is still in a closed state for a period of time, and the edge of one side of the sealing plate 1203 just touches the opening 1202 When the edges are staggered, the port 1202 is in an open state, and when the sealing plate 1203 continues to rotate, the open area of ​​the port 1202 is synchronously expanded), and the power is transmitted to the third input flat gear 1601 through the rotation of the ring gear 1204, and the receiving gear 1503 is controlled to rotate through the meshing transmission of the third input bevel gear 1602, the third output bevel gear 1603, the third transmission bevel gear 1605, the third linkage bevel gear 1606, and the third linkage flat gear 1607 in sequence, so as to drive the ball valve 1502 fixed to the receiving gear 1503 to rotate, and gradually open the air outlet 1501 (the ball valve 1502 has an eyelet, and the eyelet is opened when it rotates to align with the axis of the air outlet 1501. It is worth noting that the open state of the air outlet 1501 is not a time point, but a time period. The eyelet is opened when it is just connected to the air outlet 1501, and the degree of opening is at the maximum after it is fully aligned); S6: When the new filter element moves to the inlet position, the first door plate 306 is automatically turned over and opened by the push force of the new filter element, and the sealing plate 1203 just completely blocks and closes the opening 1202, and the ball valve 1502 just opens the air outlet 1501. At this time, the tension sensor 1403 detects that the tension value of the tension spring 1402 reaches F1, and sends a signal to the fan 105. The fan 105 starts, and at the same time, the air inlet valve 1702 is closed, and the conversion valve 1705 is opened. Clean air passes through the outlet pipe 1703, The communication pipe 1704 and the air inlet pipe 1701 flow into the purification tank 101. Because the sealing plate 1203 seals the opening 1202, the air cannot pass through the partition 1201 and can only flow into the air supply pipe 1504 from the opened air outlet 1501, and finally be discharged from the air outlet 1505, forming a wind curtain at the inlet position. When the new filter element pushes open the first door plate 306 and enters the tunnel 301, dust is prevented from entering the tunnel 301 through the opened inlet, and the surface of the new filter element is swept by wind at the same time. S7: The old filter element and the new filter element continue to move in the predetermined direction. When the new filter element completely enters the tunnel 301 and arrives near the No. 1 channel opening, the No. 1 door plate 306 automatically falls back and recloses the inlet. At this time, the old filter element is completely pushed into the tunnel 301 and reaches the N2 position. According to S4 and S5, the push plate 1004 is also completely received into the storage bin 1001. The sealing plate 1203 reopens the passage 1202, and the ball valve 1502 closes the air outlet 1501 again. The tension sensor 1403 detects that the tension value of the tension spring 1402 reaches F2, and sends a signal to the fan 105. The fan 105 stops running, and the air inlet valve 1702 is reopened, and the conversion valve 1705 is closed again. S8: At the same time as S7, the tension sensor 1403 sends a signal to the air pump 804, and the air pump 804 inflates the airbag 805 to expand the airbag 805, overcome the elastic force of the No. 2 return spring 808, and push the auxiliary push rod 806 out of the connecting frame 803. When the support plate 802 does not move, the auxiliary push plate 807 pushes the new filter element to the N2 position, and the old filter element in the N2 area is gradually pushed into the M2 position, and the new filter element replaces the old filter element and enters the N2 position; S9: Then, the motor 401 outputs power in the reverse direction. According to the power transmission relationship in S2-S7, the closing plate 303 and the material changing plate 504 drive the new filter element to move along the h3 direction from the N2 position to the M1 position, and the support plate 802 also gradually moves back to the starting position of the tunnel 301 along the h4 direction. At the same time, the lifting plate 502 compresses the lower gas hood 903, and the gas in the lower gas hood 903 flows into the gas cylinder 1002 through the No. 2 gas pipe 904, causing the plunger 1003 to move in the reverse direction in the gas cylinder 1002, causing the push plate 1004 to generate a push force on the old filter element at the M2 position at this time, and the movement of the old filter element overcomes the elastic force of the No. 3 return spring 1104, so that the No. 2 door plate 1103 is pushed open from the warehouse outlet; S10: When the support plate 802 passes the No. 1 door panel 306, according to S6 and S7, the air outlet 1505 forms an air curtain at the opened inlet again. When the new filter element completely enters the M1 position, the entire replacement process is completed. The old filter element is finally completely exposed outside the tunnel 301 and is manually removed. After removal, under the elastic force recovery action of the No. 3 reset spring 1104, the No. 2 door panel 1103 closes the outlet again.

10. A purification method for air pollution control, characterized in that: Using the air pollution control purification equipment as claimed in claim 9, The following steps are involved: S1: The user places the new filter element stably at the starting end N1 of the tunnel (301) and makes it close to the support plate (802) and the auxiliary push plate (807); S2: The user starts the motor (401) to control the driving gear (402) to rotate. Through the meshing transmission effect, the driving gear (402) outputs power to the driven gear (403). The driven gear (403) drives the stud (404) to rotate together, and drives the No. 1 screw sleeve (501) threadedly connected to the stud (404) to move upward along the stud (404). With the help of the synchronously moving upward material replacement plate (504), the old filter element originally located at the M1 position in the replacement bin (102) is gradually pushed into the tunnel (301) along the h1 direction. Under the pushing action of the old filter element, the closing plate (303) overcomes the elastic force of the No. 1 return spring (304), moves upward along the guide column (302), opens the No. 1 channel opening, and the old filter element enters the tunnel (301) near the N2 position through the No. 1 channel opening; S3: Simultaneously with S2, the rotating stud (404) and the linkage gear (405) transmit power to the first input bevel gear (606) through the meshing transmission action of the first input spur gear (601), the first transmission main spur gear (602), the first transmission sub-spur gear (603) and the first linkage main spur gear (604) in sequence, and transmit power to the screw rod (704) again according to the meshing transmission action of the first output bevel gear (702), the first linkage sub-spur gear (701) and the first output spur gear (703) in sequence, and the second screw sleeve (801) is controlled by the rotating screw rod (704) to move from the starting end of the tunnel (301) into the tunnel (301), and the new filter element is pushed into the tunnel (301) along the h2 direction with the help of the synchronously moving support plate (802), gradually approaching the N2 position; S4: Simultaneously with S2 and S3, the lifting plate (502) cooperates with the top plate (202) in the process of moving upward to continuously compress the upper gas cover (901), so that the gas in the upper gas cover (901) flows into the gas cylinder (1002) through the No. 1 gas pipe (902), and the gas pressure causes the plunger (1003) to move in the gas cylinder (1002), so that the push plate (1004) continuously moves toward the side of the storage bin (1001) and away from the No. 2 door panel (1103); S5: Simultaneously with S2, S3 and S4, the linkage gear (405) transmits power to the second input spur gear (1301) meshing with it, and sequentially controls the gear ring (1204) to rotate through the meshing transmission of the second input bevel gear (1303), the second output bevel gear (1304) and the second output spur gear (1305), driving the sealing plate (1203) fixed to the gear ring (1204) to rotate, gradually blocking and sealing the opening (1202), and through the gear ring ( 1204) rotates to transmit power to the third input spur gear (1601), and then sequentially through the meshing transmission of the third input bevel gear (1602), the third output bevel gear (1603), the third transmission bevel gear (1605), the third linkage bevel gear (1606), and the third linkage spur gear (1607), controls the rotation of the receiving gear (1503), drives the ball valve (1502) fixed to the receiving gear (1503) to rotate, and gradually opens the air outlet (1501); S6: When the new filter element moves to the inlet position, the first door plate (306) automatically flips open due to the push force of the new filter element, and the sealing plate (1203) just completely blocks and closes the opening (1202). The ball valve (1502) just opens the air outlet (1501). At this time, the tension sensor (1403) detects that the tension value of the tension spring (1402) reaches F1, and sends a signal to the fan (105). The fan (105) starts, and at the same time, the air inlet valve (1702) is closed, and the conversion valve (1705) is opened. Clean air passes through the outlet pipe (1703), The communication pipe (1704) and the air inlet pipe (1701) flow into the purification tank (101). Since the sealing plate (1203) seals the opening (1202), the air cannot pass through the partition plate (1201) and can only flow into the air supply pipe (1504) from the opened air outlet (1501) and finally be discharged from the air outlet nozzle (1505), forming a wind curtain at the inlet position. When the new filter element pushes open the first door plate (306) and enters the tunnel (301), dust is prevented from entering the tunnel (301) through the opened inlet, and the surface of the new filter element is swept by wind at the same time. S7: the old filter element and the new filter element continue to move in a predetermined direction. When the new filter element completely enters the tunnel (301) and reaches the vicinity of the No. 1 channel opening, the No. 1 door plate (306) automatically falls back and recloses the inlet. At this time, the old filter element is completely pushed into the tunnel (301) and reaches the N2 position. According to S4 and S5, the push plate (1004) is also completely retracted into the storage bin (1001). The sealing plate (1203) reopens the passage (1202), the ball valve (1502) closes the air outlet (1501), and the tension sensor (1403) detects that the tension value of the tension spring (1402) reaches F2, and sends a signal to the fan (105). The fan (105) stops running, and at the same time, the air inlet valve (1702) is reopened and the conversion valve (1705) is closed again. S8: At the same time as S7, the tension sensor (1403) sends a signal to the air pump (804), and the air pump (804) inflates the airbag (805), causing the airbag (805) to expand, thereby overcoming the elastic force of the No. 2 return spring (808), and pushing the auxiliary push rod (806) out of the connecting frame (803). When the support plate (802) does not move, the auxiliary push plate (807) pushes the new filter element to the N2 position, and the old filter element in the N2 area is gradually pushed into the M2 position, and the new filter element replaces the old filter element and enters the N2 position; S9: Then, the motor (401) outputs power in the reverse direction. According to the power transmission relationship in S2-S7, the closing plate (303) and the material replacement plate (504) drive the new filter element to move along the h3 direction from the N2 position to the M1 position, and the support plate (802) also gradually moves back to the starting position of the tunnel (301) along the h4 direction. At the same time, the lifting plate (502) compresses the lower gas hood (903), and the gas in the lower gas hood (903) flows into the gas cylinder (1002) through the No. 2 gas pipe (904), causing the plunger (1003) to move in the reverse direction in the gas cylinder (1002), causing the push plate (1004) to generate a push force on the old filter element at the M2 position at this time, and the movement of the old filter element overcomes the elastic force of the No. 3 return spring (1104), so that the No. 2 door plate (1103) is pushed open from the exit; S10: When the support plate (802) passes the first door panel (306), according to S6 and S7, the air outlet (1505) forms an air curtain at the opened inlet again. When the new filter element completely enters the M1 position, the entire replacement process is completed. The old filter element is finally completely exposed outside the tunnel (301) and is manually removed. After removal, under the elastic force recovery action of the third return spring (1104), the second door panel (1103) closes the outlet again.
