Description

Technical Field

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

[0002] Currently, many methods for air pollution control in the atmosphere adopt a multi-stage filtration system. The polluted air is sent into the filtration system, and the pollutant particles in the air are intercepted by the filter layer to achieve a purification effect. The filter layer is generally arranged in the form of a detachable filter element. After being used for a period of time, the filter element will remain contaminated. Continuing to use it will affect the filtration and purification of the air. Therefore, it is necessary to replace the old filter element to keep the filtration system's purification ability.

[0003] When replacing the filter element of the purification device, the device needs to be opened, the old filter element is taken out, then the new filter element is put in and fixed, and the device is closed. The entire process is manual disassembly and assembly, which is rather troublesome. Moreover, due to the proficiency of the replacement operation and the structural dimensions of the filter element, when replacing, the device is in an open state for a long time, and it is easy for dust to fall into the device, resulting in internal pollution and affecting the purification effect.

[0004] Therefore, in view of the above problems, a purification device that is convenient for automatic filter element replacement can be designed to synchronously take out the old filter element and put in the new filter element, reducing the time for opening the internal space of the device when replacing the filter element and reducing the entry of dust and pollutants.

[0015] A purification method for air pollution control, using a purification device for air pollution control as described above, includes the following steps:

[0016] S1: The user stably places a new filter element at the starting end N1 position of the tunnel and presses it tightly against the backing plate and the auxiliary push plate;

[0017] S2: The user starts the motor to control the rotation of the driving gear. Through the meshing transmission effect, the driving gear outputs power to the driven gear. The driven gear drives the stud to rotate together and drives the first screw sleeve threadedly connected to the stud to move upward along the stud. With the help of the feeding plate that moves upward synchronously, the old filter element originally at the M! 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 first return spring and moves upward along the guide post to open the first channel opening. The old filter element enters the tunnel near the N2 position through the first channel opening;

[0018] S3: Simultaneously with S2, the rotating stud and linkage gear transmit power to the first input bevel gear through the meshing transmission action 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. The power is then transmitted to the screw rod again through the meshing transmission action of the first output bevel gear, the first linkage sub-spur gear, and the first output spur gear in sequence. The rotating screw rod controls the No. 2 screw sleeve to move from the starting end of the tunnel into the tunnel. With the help of the synchronously moving support plate, the new filter element is pushed into the tunnel along the h2 direction, gradually approaching the N2 position.

[0019] S4: Simultaneously with S2 and S3, the lifting plate cooperates with the top plate in its upward movement to continuously compress the upper air hood, causing the gas in the upper air hood to flow into the air cylinder through the No. 1 air pipe. The gas pressure causes the plunger to move in the air cylinder, causing the push piece to continuously move toward the storage bin and away from the No. 2 door panel.

[0020] 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. The power is then transmitted 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, gradually opening the air outlet.

[0021] S6: When the new filter element moves to the inlet position, the No. 1 door panel automatically flips open due to the pushing force of the new filter element, and the sealing plate just completely blocks and closes the opening. 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, sends a signal to the fan, and the fan starts. At the same time, the air inlet valve closes and the conversion valve opens. Clean air flows into the purification tank through the outlet pipe, the connecting pipe and the air inlet pipe in sequence. Because the sealing plate blocks 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 an air curtain at the inlet position. In the process of the new filter element pushing up the No. 1 door panel and entering the tunnel, the air curtain prevents dust from entering the tunnel through the opened inlet and at the same time blows the surface of the new filter element with wind.

[0022] 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 reaches near the No. 1 channel opening, the No. 1 door panel automatically drops back to re-close the inlet opening. At this time, the old filter element is completely pushed into the tunnel to reach the N2 position. According to S4 and S5, the pushing piece is also completely retracted into the storage bin, the sealing plate re-opens the through port, the ball valve re-closes the air outlet, the tension sensor detects that the tension value of the tension spring reaches F2, sends a signal to the fan, and the fan stops running. At the same time, the intake valve re-opens and the conversion valve re-closes;

[0023] S8: When the tension sensor (1403) detects that the tension value of the tension spring (1402) reaches F2, the tension sensor sends a signal to the air pump, and the air pump inflates the airbag to make the airbag expand, overcoming the elastic force of the No. 2 return spring, and pushing the auxiliary push rod outwards towards the connecting frame. Without the backing plate moving, the auxiliary push plate pushes the new filter element towards the N2 position, gradually pushing the old filter element in the N2 area into the M2 position, and the new filter element replaces the old filter element to enter the N2 position;

[0024] 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-changing plate drive the new filter element to move along the h3 direction from the N2 position to the M1 position, and the backing 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, making the plunger move reversely in the air cylinder, and the pushing piece generates a pushing force on the old filter element at the M2 position at this time. Through the movement of the old filter element, the elastic force of the No. 3 return spring is overcome, and the No. 2 door panel is pushed open from the outlet opening;

[0025] S10: When the backing plate passes by the No. 1 door panel, according to S6 and S7, the air outlet nozzle forms an air curtain at the opened inlet opening again. When the new filter element completely enters the M1 position, the entire replacement process ends. The old filter element is finally completely exposed outside the tunnel and is taken away manually. After being taken away, under the restoring action of the elastic force of the No. 3 return spring, the No. 2 door panel re-closes the outlet opening.

[0026] Advantages of the present invention:

[0027] 1. By means of the closed bin assembly provided at the top of the purification tank, cooperating with the synchronous output of power of the lifting assembly and the pushing assembly, the replacement of the filter element can be completed in a closed space. Compared with the traditional filter element replacement method, the internal spaces of the purification tank and the replacement bin will not be exposed to the environment for a long time and thus be contaminated;

[0028] 2. While feeding in the new filter element, an air curtain can be formed at the inlet opening of the tunnel to prevent dust from entering the tunnel through the opened No. 1 door panel, and it is less likely for the tunnel to be contaminated;

[0029] 3. The air curtain can not only isolate dust from entering, but also play a role in cleaning the surface of the new filter element by blowing with surface wind, removing a small amount of dust contaminated on the surface of the filter element;

[0030] 4. By using the fan in the purification tank as the power source for forming the air curtain, no additional electromechanical equipment is required, and the overall manufacturing cost and operating cost are lower;

[0031] 5. By alternately opening and closing the intake valve and the conversion valve, during the filter element replacement period, the intake passage can be adjusted, and the purified air is used as the air source output by the air curtain, which contains less pollutants;

[0032] 6. The fan starts only when the closing plate closes the through-hole, preventing the fan from continuously operating during the filter element replacement period and causing a large amount of polluted air to rush into the replacement bin. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0050] The present invention will be further described below in conjunction with the drawings and embodiments.

[0051] Please refer to Figures 1 - 16, the present invention provides an embodiment: a purification device for air pollution control, including a purification tank 101, a wind guiding component installed on the purification tank 101, a driving chamber 201 installed at the lower end of the purification tank 101, a closed chamber component installed at the upper end of the purification tank 101, a driving component installed in the driving chamber 201, and a lifting component installed on the driving component. A replacement chamber 102 is provided on the purification tank 101, and a filter element is detachably installed in the replacement chamber 102. The replacement chamber 102 is connected to the driving chamber 201 and the closed chamber component. One end of the closed chamber component is provided with an inlet port, and the other end is provided with an outlet port. The driving component is used to drive the lifting component to move in the vertical direction, and the lifting component is used to drive the filter element to move in the vertical direction. A first-stage transmission component is installed on the driving component, and a pushing component is installed on the closed chamber component. The input end of the first-stage transmission component is connected to the output end of the driving component, and the first-stage transmission component is used to drive the pushing component to move in the horizontal direction; when the lifting component moves upward in the vertical direction, the pushing component moves from one side of the inlet port to one side of the outlet port; when the lifting component moves downward in the vertical direction, the pushing component moves from one side of the outlet port to one side of the inlet port; an air inflation component is installed on the lifting component, a recovery component and a switch component are installed on the closed chamber component. The air inflation component is used to input gas into the recovery component, the switch component is used to open or close the outlet port, and the recovery component is used to drive the filter element to move towards the outlet port; when the lifting component moves upward in the vertical direction, the switch component closes the outlet port; when the lifting component moves downward in the vertical direction, the switch component opens the outlet port. The user uses a detection tool to detect on one side of the air outlet 104. When the detected air quality does not meet the purification standard, it means that the filter element needs to be replaced. Place a new filter element on the closed chamber component, start the driving component (it can be started manually or controlled by an industrial computer at an appropriate time point), control the lifting component to push the old filter element out into the closed chamber component (from M1 to N2). At the same time, transmit the power of the driving component to the pushing component through the first-stage transmission component, so that the pushing component synchronously sends the new filter element close to the old filter element (from N1 to N2). The old filter element enters the M2 position under the pushing action of the new filter element. Then the driving component outputs power in the reverse direction, controls the lifting component to send the new filter element into the replacement chamber 102, and at the same time the pushing component also returns to the initial position (N1). During this process, the air inflation component inputs gas into the recovery component, so that the recovery component pushes the old filter element at M2 out of the closed chamber component through the outlet port (the switch component opens the outlet port).

When replacing the filter element, the intake valve 1702 is in the closed state, and the conversion valve 1705 is in the open state, so that the polluted gas cannot enter the purification tank 101 through the intake pipe 1701. The tunnel 301 has a two-section structure, including an open section and a closed section. The closed section covers the first channel opening, and the open section is used to place the new filter element. The first door panel 306 is between the open section and the closed section. The first door panel 306 can be installed on the tunnel 301 by a rotating shaft. When the new filter element and the pushing component pass through, the first door panel 306 can rotate towards both sides to open the bin inlet. The old filter element enters the tunnel 301 from the replacement bin 102 along the h1 direction through the first channel opening (from M1 to N2). The old filter element pushes the closing plate 303 upwards, and the first return spring 304 contracts. The new filter element enters the replacement bin 102 from the tunnel 301 along the h3 direction through the first channel opening. The closing plate 303 synchronously moves downwards under the elastic restoring force of the first return spring 304 to re-close the first channel opening (in actual use, the elastic force of the first return spring 304 is much greater than the air flow force, so that the closing plate 303 maintains the state of closing the first channel opening).;

The first input spur gear 601 meshes with the linkage gear 405. 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 are sequentially meshed and connected. The first input bevel gear 606 is used to drive the first output bevel gear 702 to rotate, the first linkage sub-spur gear 701 is used to drive the first output spur gear 703 to rotate, and the screw rod 704 is used to drive the pushing component to move in the horizontal direction. The motor 401 controls the driving gear 402 to rotate. Through the meshing transmission of the driving gear 402 and the driven gear 403, the driven gear 403 rotates, and the stud 404 and the linkage gear 405 rotate together with the driven gear 403. The rotating linkage gear 405 outputs power to the first input spur gear 601, and the first input spur gear 601 transmits power to the first transmission main spur gear 602, the first transmission sub-spur gear 603, and the first linkage main spur gear 604 step by step. The first connecting rod 605 and the first input bevel gear 606 rotate synchronously with the first linkage main spur gear 604. Under the meshing transmission, the first output bevel gear 702 and the first linkage sub-spur gear 701 rotate, and the first output spur gear 703 meshing with the first linkage sub-spur gear 701 rotates immediately, causing the screw rod 704 to rotate. Through the above continuous power transmission, the lifting component and the pushing component move simultaneously (in practical applications, various gear transmission structures can be replaced by chain drives, belt drives, etc.).

(Under normal conditions, the material changing plate 504 is in the No. 2 channel opening to close the No. 2 channel opening.) During the rotation of the stud 404, the No. 1 screw sleeve 501 threadedly connected thereto moves in the vertical direction (upward when ejecting the old filter element and downward when replacing the new filter element), driving the lifting plate 502, the support 503 and the material changing plate 504 to move synchronously (in actual application, the inner wall of the drive chamber 201 or other guide structure is provided to guide the lifting plate 502). During the upward and downward movement of the lifting plate 502, the tension spring 1402 is stretched, causing its tension value to change. The tension sensor 1403 detects the change in the tension value of the tension spring 1402 and outputs a control signal to the industrial computer to automatically control the fan 105, the intake valve 1702, the conversion valve 1705 and the pushing component.

[0055] See also Figures 1 - 2 、 Figure 7 and Figures 9 - 10, in this embodiment, the pushing component includes a second screw sleeve 801 movably connected in the sliding channel 305, a backing plate 802 fixedly installed on the second screw sleeve 801, a connecting frame 803 fixedly installed on the backing plate 802, an air pump 804 installed on the connecting frame 803, an airbag 805 installed in the connecting frame 803, an auxiliary push rod 806 movably connected in the connecting frame 803, an auxiliary push plate 807 fixedly connected to the auxiliary push rod 806, and a second return spring 808 with one end connected to the auxiliary push rod 806. The second screw sleeve 801 is threadedly connected to the screw rod 704. The screw rod 704 is used to drive the second screw sleeve 801 to move along the axis of the sliding channel 305. The air pump 804 is used to fill the airbag 805 with gas. The airbag 805 is used to drive the auxiliary push rod 806 and the auxiliary push plate 807 to move horizontally. The other end of the second return spring 808 is fixedly connected to the connecting frame 803. During the rotation of the screw rod 704, the second screw sleeve 801 threadedly connected to it moves horizontally along the axis direction of the screw rod 704 (along the h2 or h4 direction). The backing plate 802 and the connecting frame 803 move synchronously with the second screw sleeve 801. When the backing plate 802 pushes the new filter element to a position where it is closely attached to the old filter element lifted into the tunnel 301, at this time, 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 inflated 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 makes the auxiliary push plate 807 push the new filter element into the N2 position, pushing the old filter element at this position into the M2 position. At the same time, the new filter element enters the N2 position (between the closing plate 303 and the material changing plate 504). 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 second return spring 808, the auxiliary push rod 806 retracts into the connecting frame 803 (in actual application, another sensor can be set on the second return spring 808 to detect the in-place state of the new filter element).

[0056] Please refer to Figures 1 - 4 and Figures 11 - 12, in this embodiment, the inflation component includes an upper air hood 901 installed between the lifting plate 502 and the top plate 202, a first air pipe 902 with one end connected to the upper air hood 901, a lower air hood 903 installed between the bottom wall of the drive chamber 201 and the lifting plate 502, and a second air pipe 904 with one end connected to the lower air hood 903. The other ends of the first air pipe 902 and the second air pipe 904 are both connected to the recovery component. Both the upper air hood 901 and the lower air hood 903 are used to input gas into the recovery component; the recovery component includes a storage bin 1001 installed on the tunnel 301, an air cylinder 1002 installed on the storage bin 1001, a plunger 1003 movably connected in the air cylinder 1002, and a push plate 1004 fixedly connected to the end of the plunger 1003. The push plate 1004 is on the same horizontal straight line as the outlet. When the first air pipe 902 inputs gas into the air cylinder 1002, the plunger 1003 and the push plate 1004 approach the outlet; when the second air pipe 904 inputs gas into the air cylinder 1002, the plunger 1003 and the push plate 1004 move away from the outlet; the switch component includes a bottom plate 1101 fixedly installed on the tunnel 301, a guide rod 1102 installed on the bottom plate 1101, a second door plate 1103 movably connected to the guide rod 1102, and a third return spring 1104 installed on the guide rod 1102. One end of the third return spring 1104 is connected to the guide rod 1102, and the other end is connected to the second door plate 1103. The second door plate 1103 is used to open or close the outlet. When the motor 401 outputs reverse power to control the lifting component to move along the h3 direction and the pushing component to move along the h4 direction, the lifting plate 502 compresses the lower air hood 903, causing the gas in the lower air hood 903 to flow 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 the old filter element at the M2 position is pushed by the push plate 1004 (when the lifting component moves along the h1 direction and the pushing component moves along the h3 direction, the lifting plate 502 compresses the upper air hood 901, and the gas in the upper air hood 901 flows into the air cylinder 1002 through the first air pipe 902, causing the plunger 1003 and the push plate 1004 to move towards the storage bin 1001 side. When the new filter element enters the N2 position, the push plate 1004 is in the state of being completely retracted into the storage bin 1001). Under the pushing action of the old filter element, the second door plate 1103 overcomes the elastic force of the third return spring 1104 and moves on the bottom plate 1101 along the guide rod 1102 to open the outlet, and the old filter element also leaves the tunnel 301 and is taken out manually (or automatically taken out by an external manipulator). After being taken out, the second door plate 1103 automatically closes the outlet again under the elastic restoring force of the third return spring 1104.

[0057] Please refer to Figures 1 - 4 , Figures 7 - 8 and Figures 13 - 16, in this embodiment, a partition component and a air supply component are installed in the purification tank 101, a secondary transmission component is installed on the drive component, and a tertiary transmission component is installed on the partition component. The partition component is used to open or close the channel between the fan 105 and the replacement bin 102. The input end of the partition component is connected to the output end of the secondary transmission component, the input end of the tertiary transmission component is connected to the output end of the partition component, and the output end of the tertiary transmission component is connected to the input end of the air supply component. The air supply component is used to output the gas in the purification tank 101 to the position of the inlet of the bin; The partition component includes a partition plate 1201 fixedly installed in the purification tank 101, a through hole 1202 opened on the partition plate 1201, a sealing plate 1203 movably connected to the partition plate 1201, and a gear ring 1204 fixedly installed on the sealing plate 1203. The sealing plate 1203 opens or closes the through hole 1202 by rotating; The air supply component includes an air outlet 1501 fixedly installed on the purification tank 101, a ball valve 1502 movably connected to the air outletThe third linkage spur gear 1607 is movably connected to the purification tank 101, the third linkage spur gear 1607 is meshed with the receiving gear 1503, the ring gear 1204 is used to drive the third input spur gear 1601 to rotate, the third input bevel gear 1602 is used to drive the third output bevel gear 1603 to rotate, the third transmission bevel gear 1605 is used to drive the third linkage bevel gear 1606 to rotate, and the third linkage spur gear 1607 is used to drive the receiving gear 1503 to rotate. 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 rotation of the ring gear 1204 meshing with the second output flat gear 1305, which also causes the sealing plate 1203 to rotate. During the rotation process, the sealing plate 1203 experiences two states of closing and opening the opening 1202. 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 through the partition 1201 to the replacement chamber 102 and the air outlet pipe 1703 side (when the push component 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. 1602 is in the open state), 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 pushing component 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 pushing component moves to the No. 1 door panel 30 6, lifting plate 502 is also at the corresponding height, causing tension spring 1402 to generate the corresponding tension value F1. At this time, tension sensor 1403 sends a signal to fan 105, and also to inlet valve 1702 and switching valve 1705. Inlet valve 1702 closes, and switching valve 1705 opens. After fan 105 starts running, the clean air in the purification chamber on the side of outlet 104 is sucked into purification tank 101 through connecting pipe 1704 by fan 105. Because port 1202 is closed at this time, the air can only enter air duct 1504 through outlet 1501 and be discharged from outlet nozzle 1505, forming an air curtain at the inlet, preventing dust from entering tunnel 301.

[0058] See also Figures 1 - 16, in this embodiment, the present invention provides a purification method for air pollution control, using a purification device for air pollution control as described above, including the following steps:

[0059] S1: The user stably places a new filter element at the starting end N1 position of the tunnel 301 and closely adheres it to the backing plate 802 and the auxiliary push plate 807;

[0060] S2: The user starts the motor 401 to control the rotation of the driving gear 402. 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 first screw sleeve 501 threadedly connected to the stud 404 to move upward along the stud 404. With the help of the simultaneously moving 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 first return spring 304 and moves upward along the guide post 302 to open the first channel opening. The old filter element enters the tunnel 301 near the N2 position through the first channel opening;

[0061] S3: Simultaneously with S2, through the successive meshing transmissions 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, the rotating stud 404 and the linkage gear 405 transmit power to the first input bevel gear 606, and then, according to the successive meshing transmissions of the first output bevel gear 702, the first linkage sub-spur gear 701 and the first output spur gear 703, the power is transmitted to the screw rod 704. By controlling the rotation of the screw rod 704, the second screw sleeve 801 is moved from the starting end of the tunnel 301 into the tunnel 301. With the help of the simultaneously moving backing plate 802, the new filter element is pushed into the tunnel 301 along the h2 direction and gradually approaches the N2 position;

[0062] S4: Simultaneously with S2 and S3, during the upward movement of the lifting plate 502, in cooperation with the top plate 202, the upper air hood 901 is continuously compressed, so that the gas in the upper air hood 901 flows into the air cylinder 1002 through the first air pipe 902. Through the gas pressure, the plunger 1003 moves in the air cylinder 1002, and the push piece 1004 continuously moves towards the storage bin 1001 side and away from the second door panel 1103 (the first air pipe 902 and the second air pipe 904 are respectively connected to both ends of the air cylinder 1002. After the gas flows in, two pressures in opposite directions are formed, causing the plunger 1003 to move in different directions);

[0063] S5: Simultaneously with S2, S3, and S4, the linkage gear 405 transmits power to the second input spur gear 1301 meshing with it. Through the meshing transmission of the second input bevel gear 1303, the second output bevel gear 1304, and the second output spur gear 1305 in sequence, it controls the rotation of the ring gear 1204, drives the closing plate 1203 fixed to the ring gear 1204 to rotate, and gradually blocks and closes the through-port 1202 (it should be noted that both the closing plate 1203 and the through-port 1202 can be designed as fan-shaped structures. The size of the closing plate 1203 is larger than that of the through-port 1202. The opening or closing state of the through-port 1202 is not a time point but a time period. When the closing plate 1203 rotates to the through-port 1202, it closes it. When it continues to rotate, because the size of the closing plate 1203 is large, the through-port 1202 remains closed for a period of time. When the edge on one side of the closing plate 1203 just intersects with the edge of the through-port 1202, the through-port 1202 is in the open state. When the closing plate 1203 continues to rotate, the opening area of the through-port 1202 expands synchronously), and through the rotation of the ring gear 1204, transmits power to the third input spur gear 1601. 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 in sequence, it 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 (there are holes in the ball valve 1502. When the holes rotate to align with the axis of the air outlet 1501, it is opened. It should be noted that the opening state of the air outlet 1501 is not a time point but a time period. When the holes just communicate with the air outlet 1501, it is opened. When they are completely aligned, the opening degree is in the maximum state);

[0064] S6: When the new filter element moves to the position of the inlet bin, the first door panel 306 automatically flips open under the top thrust of the new filter element. At this time, the closing plate 1203 just completely blocks and closes the through-port 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, sends a signal to the fan 105, the fan 105 starts, at the same time the intake valve 1702 closes, and the conversion valve 1705 opens. Clean air flows into the purification tank 101 through the air outlet pipe 1703, the connecting pipe 1704, and the air inlet pipe 1701 in sequence. Because the closing plate 1203 closes the through-port 1202, air cannot pass through the partition 1201 and can only flow into the air duct 1504 from the opened air outlet 1501 and finally be discharged from the air outlet nozzle 1505, forming an air curtain at the position of the inlet bin. During the process of the new filter element pushing open the first door panel 306 and entering the tunnel 301, it prevents dust from entering the tunnel 301 through the opened inlet bin and simultaneously blows the surface of the new filter element with wind;

[0065] 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 reaches near the first channel entrance, the first door panel 306 automatically falls back to re-close the bin entrance. 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 pushing piece 1004 is also completely retracted into the storage bin 1001, the sealing plate 1203 re-opens the through hole 1202, the ball valve 1502 re-closes the air outlet 1501, the tension sensor 1403 detects that the tension value of the tension spring 1402 reaches F2, sends a signal to the fan 105, the fan 105 stops running, and at the same time the intake valve 1702 re-opens and the switching valve 1705 re-closes;

[0066] S8: When the tension sensor (1403) detects that the tension value of the tension spring (1402) reaches F2, the tension sensor 1403 sends a signal to the air pump 804. The air pump 804 inflates the airbag 805 to make the airbag 805 expand, overcoming the elastic force of the second return spring 808, and pushes the auxiliary push rod 806 outwards towards the connecting frame 803. Without the backing plate 802 moving, the auxiliary push plate 807 pushes the new filter element towards the N2 position, gradually pushing the old filter element in the N2 area into the M2 position, and the new filter element replaces the old filter element in the N2 position;

[0067] 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 along the h3 direction, moving from the N2 position to the M1 position, and the backing 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 air hood 903, and the gas in the lower air hood 903 flows into the air cylinder 1002 through the second air pipe 904, making the plunger 1003 move in the air cylinder 1002 in the reverse direction, so that the pushing piece 1004 generates a pushing force on the old filter element at the M2 position at this time. Through the movement of the old filter element, it overcomes the elastic force of the third return spring 1104 and pushes the second door panel 1103 away from the bin outlet;

[0068] S10: When the backing plate 802 passes by the first door panel 306, according to S6 and S7, the air outlet nozzle 1505 forms an air curtain at the opened bin entrance again. When the new filter element completely enters the M1 position, the entire replacement process ends. The old filter element is finally completely exposed outside the tunnel 301 and is taken away manually. After being taken away, under the restoring action of the elastic force of the third return spring 1104, the second door panel 1103 re-closes the bin outlet.

8. A purification method for air pollution control, characterized in that: Using the air pollution control purification equipment as claimed in claim 7, 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, 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 changing plate (504), the old filter element originally at the M1 position in the replacement chamber (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) and moves upward along the guide column (302), opening the No. 1 channel. The old filter element enters the tunnel (301) near the N2 position through the No. 1 channel. S3: Simultaneously with S2, 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) are meshed and driven in sequence, and the rotating stud (404) and the linkage gear (405) transmit power to the first input bevel gear (606), and again transmit power to the screw (704) according to the meshed and driven action of the first output bevel gear (702), the first linkage sub-spur gear (701) and the first output spur gear (703). 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 by means 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). The gas pressure causes the plunger (1003) to move in the gas cylinder (1002), causing the push piece (1004) to continuously move 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) meshed with it, and sequentially controls the ring gear (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 ring gear (1204) to rotate, gradually blocking and sealing the opening (1202), and through the ring gear ( The rotation of the third input bevel gear (1204) transmits power to the third input spur gear (1601), which in turn is meshed with 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), thereby controlling the rotation of the receiving gear (1503), driving the ball valve (1502) fixed to the receiving gear (1503) to rotate, and gradually opening 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 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 switching valve (1705) is opened. Clean air passes through the outlet pipe (1703) and the air outlet pipe (1703) in sequence. 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 (1201) and can only flow into the air delivery pipe (1504) from the opened air outlet (1501) and finally be discharged from the air outlet nozzle (1505), forming an air curtain at the inlet position. When the new filter element opens the first door plate (306) and enters the tunnel (301), the air is prevented from entering the tunnel (301) 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 (301) and arrives near the No. 1 channel opening, the No. 1 door panel (306) automatically falls back and recloses the inlet. At this time, the old filter element is completely pushed into the tunnel (301) and arrives at 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 opening (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. At the same time, the air inlet valve (1702) is reopened and the switching valve (1705) is reclosed. S8: When the tension sensor (1403) detects that the tension value of the tension spring (1402) reaches F2, 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, overcoming the elastic force of the second 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 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 (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. The movement of the old filter element overcomes the elastic force of the No. 3 return spring (1104), and 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 of the third return spring (1104), the second door panel (1103) closes the outlet again.
