Description

Technical Field

[0001] The present invention relates to the technical field of solid waste pollution treatment, and particularly to a flying floc collection device for textile production and preparation. Background Art

[0002] In the process of textile production, the generation of flying flocs (including cotton flocs, chemical fiber staple fibers, etc.) as typical industrial solid wastes is inevitable. Such fiber solid wastes will not only adhere to the surface of semi-finished products to form secondary pollution, resulting in a decrease in product qualification rate, but also, due to their low density and high dispersion characteristics, will be suspended in the production environment air for a long time, causing air pollution, endangering the health of operators, and facing increasingly strict environmental protection regulations due to improper solid waste disposal.

[0003] In the prior art, a single-layer filter screen or a simple dust suction structure is mostly used, and the interception ability of flying flocs is limited. When the flying floc concentration is high, the filter screen is easily blocked quickly. And due to the content of flying flocs in the air, it is necessary to frequently clean or replace the filter screen manually, resulting in an increase in downtime, affecting production efficiency. And because the content of flying flocs in the air is not constant, if the filter screen is cleaned or replaced regularly, the timing cannot be accurately grasped. The filter screen is replaced before reaching the blockage threshold, resulting in material waste and increased energy consumption. Delaying replacement will cause the failure of flying floc separation, and it is easy to cause serious blockage and damage of the filter screen.

[0004] Aiming at the above technical problems, the present invention discloses a flying floc collection device for textile production and preparation. When the present invention separates solid wastes in the air through a filter plate, the inner tube is horizontally moved by air pressure difference to realize the rapid switching of the two-end filter components, ensuring that when one end is blocked, the air flow is seamlessly transferred to the standby path, avoiding shutdown, etc. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a flying floc collection device for textile production and preparation, so as to solve the technical problems in the prior art that when separating and collecting flying flocs in the air, because the content of flying flocs in the air is not constant, if the filter screen is cleaned or replaced regularly, the timing cannot be accurately grasped. The filter screen is replaced before reaching the blockage threshold, resulting in material waste and increased energy consumption. Delaying replacement will cause the failure of flying floc separation, and it is easy to cause serious blockage and damage of the filter screen. The present invention has the advantages of driving the inner tube to horizontally move by air pressure difference, realizing the rapid switching of the two-end filter components, ensuring that when one end is blocked, the air flow is seamlessly transferred to the standby path, and avoiding shutdown.

[0006] The present invention is implemented by the following technical scheme: The present invention discloses a flying catkins collection device for textile production and preparation, comprising a bellows and an air intake pipe, the air intake pipe is installed on the bellows, one end of the air intake pipe is connected to a connecting pipe and they are perpendicular to each other, and both ends of the connecting pipe are connected to the bellows through fixed pipes respectively; Both ends of the connecting pipe are provided with filter components, which filter flying catkins in the air on the circulation route between the connecting pipe and the fixed pipe. The fixed pipes at both ends of the connecting pipe switch the connection state with the air intake pipe through the switching components. The switching component is arranged inside the connecting pipe.

[0007] Furthermore, the switching assembly includes an inner tube, a partition and a connecting port. The inner tube is arranged inside the connecting tube and slidingly and sealingly cooperates with the connecting tube. The partition is fixedly arranged in the middle section of the inner tube to divide the inner tube into two compartments. Two connecting ports are arranged along the axial direction of the inner tube. The two connecting ports are respectively opened on the tube walls of the two compartments for connecting with the intake pipe.

[0008] Furthermore, the filter assembly includes a movable ring, a cylinder, a filter plate and a trigger member. The movable ring is movably arranged inside the inner tube, the cylinder is fixedly arranged on the side of the movable ring facing the pipe mouth, the filter plate is installed in the cylinder, and the trigger member is arranged on the side of the movable ring facing the pipe mouth for triggering the switching assembly.

[0009] Furthermore, the trigger member includes an insertion strip, a second spring and a clearance groove. One end of the insertion strip is fixedly connected to the movable ring, and the other end passes through the positioning member. The second spring is arranged on the outside of the insertion strip and is located between the movable ring and the positioning member. The clearance groove is opened on the insertion strip for cooperating with the positioning member.

[0010] Furthermore, the positioning member includes a positioning ring, a telescopic rod and a spring. The positioning ring is fixedly arranged at one end of the inner tube, and the telescopic rod is movably arranged inside the positioning ring along the radial direction of the positioning ring for cooperating with the socket on the connecting tube. A spring set is arranged outside the telescopic rod for providing a reset force.

[0011] Furthermore, it also includes a limit assembly, which includes a limit ring, a piston disc and a limit rod. The limit ring is fixedly sleeved on the end of the cylinder body, and the piston disc is slidably set in the groove hole inside the limit ring. The limit rod is set on the piston disc and is used to cooperate with the limit hole on the connecting pipe. An air cylinder is set on one side of the limit ring, and the air intake of the air cylinder controls the movement of the piston disc.

[0012] Furthermore, the withdrawal rod of the air cylinder is fixedly connected to the connecting pipe, and the outer wall of the air cylinder is also provided with a one-way pipe opening for supplying air toward the interior, and the interior of the air cylinder is connected to the groove hole inside the limiting ring through a through hole. The withdrawal rod of the air cylinder is fixedly connected to the connecting pipe, and the outer wall of the air cylinder is also provided with a one-way pipe opening for supplying air toward the interior, and the interior of the air cylinder is connected to the groove hole inside the limiting ring through a through hole.

[0013] Furthermore, the outer circumferential outer wall of the filter plate fits with the inner wall of the cylinder.

[0014] The present invention has the following advantages: (1) By automatically switching the filtering component, the present invention can avoid shutdown maintenance after the filter plate is blocked. When the air flow is blocked due to the blockage of the filter plate on one side by flying flocs, the pressure change drives the filter plate to move, triggering the unlocking of the positioning member, and the inner tube automatically switches to the other compartment, ensuring uninterrupted air purification, reducing the shutdown maintenance frequency, and thus reducing the pollution of solid waste in the working environment air.

[0015] (2) The moving distance of the filter plate in the present invention is proportional to the degree of blockage, and the blockage state is real-time feedback through the pressure change. Therefore, after the blockage occurs, the filter plate can be switched in time. If the filter screen is regularly cleaned or replaced, it is impossible to accurately grasp the timing. The filter screen is replaced before reaching the blockage threshold, resulting in material waste and increased energy consumption. Delaying the replacement will cause the failure of flying floc separation. Description of the Drawings

Detailed implementation manner

[0018] The embodiments of the present invention will be described in detail below. These embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments. In the description of the present invention, words indicating orientation or position relationship such as "front", "rear", "left", "right", etc. are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0019] This embodiment discloses a flying fluff collection device for textile production and preparation, as Figures 1 - 9 shown, including an intake pipe 1, the intake pipe 1 is installed on the air box 13, and external air is inhaled from the intake pipe 1 by the rotation of the fan inside the air box 13. The intake pipe 1 inhales air for flying fluff filtration, and a filter assembly 2 for filtering flying fluff is arranged on the intake pipe 1. The air is filtered and purified through the filter holes on the filter assembly 2, and then the flying fluff in the air is filtered and intercepted for collection, avoiding a large amount of flying fluff from being dispersed in the air; Considering that when filtering flying fluff, the filter assembly 2 may become blocked during use. As the use time increases, the blockage situation will gradually worsen. Therefore, in order to avoid affecting air purification, after using for a period of time, the filter assembly 2 needs to be disassembled and replaced or cleaned regularly. In actual situations, by regularly cleaning or replacing the filter assembly 2, due to the fact that the content of flying fluff in the air is not constant, the blockage situation of the filter assembly 2 cannot be accurately judged, resulting in an unfixed replacement cycle for the filter assembly 2. Regular replacement or cleaning may cause delays in processing, resulting in serious blockage of the filter assembly 2, thus affecting the flying fluff treatment work.

[0020] Therefore, in this embodiment, as Figures 1 - 4 shown, at one end opening of the intake pipe 1, a connecting pipe 3 is fixedly arranged, and the inside of the connecting pipe 3 is communicated with the inside of the intake pipe 1. The connecting pipe 3 is perpendicular to the intake pipe 1. One end of the intake pipe 1 is fixedly connected to the middle section of the connecting pipe 3. Both ends of the connecting pipe 3 are provided with pipe orifices 4, and the pipe orifices 4 are sealed by cover plates, and the cover plates are arranged to be detachably connected. In addition, fixing pipes 12 are respectively connected to both ends of the back surface of the connecting pipe 3. One end of the fixing pipe 12 is communicated with the air box 13, and the two fixing pipes 12 are respectively communicated with the pipe orifices 4 at both ends of the connecting pipe 3. A switching assembly 5 is further arranged inside the connecting pipe 3. The fixing pipes 12 at both ends of the connecting pipe 3 are respectively and alternately and independently communicated with the inside of the intake pipe 1 through the switching assembly 5. Specifically, when the fixing pipe 12 at one end of the connecting pipe 3 is communicated with the intake pipe 1, the fixing pipe 12 at the other end is interrupted from the inside of the intake pipe 1. In other words, when the fixing pipe 12 at one end of the connecting pipe 3 intakes air, the fixing pipe 12 at the other end closes to stop air intake.

[0021] Filter assemblies 2 are installed at both ends of the connecting pipe 3 to intercept flying fluffs. When the filter assemblies 2 are severely blocked, the communication states of the two fixing pipes 12 and the intake pipe 1 are switched through the switching assembly 5, thereby switching the filter assemblies 2.

[0022] In this embodiment, in order to enable the switching assembly 5 to be switched in time when the filter assembly 2 is severely blocked, the filter assembly 2 is set to be in an active state. Thus, when the filter assembly 2 is blocked, the filter assembly 2 will move due to the change in air pressure difference inside and outside, and trigger the switching assembly 5 through the movement of the filter assembly 2. Therefore, when the filter assembly 2 is blocked, the pipe orifice 4 can be switched in time.

[0023] Specifically, as Figures 2 - 5As shown, the switching assembly 5 includes an inner tube 501, a partition 502, a compartment 503, and a communication port 504, wherein both ends of the inner tube 501 are in an open state, the inner tube 501 is arranged inside the connecting tube 3, and the outer circumferential outer wall of the inner tube 501 is slidably sealed with the inner wall of the connecting tube 3, and a partition 502 is fixedly arranged in the middle section of the inner tube 501, and two compartments 503 are separated inside the inner tube 501 by the partition 502, and the two compartments 503 are respectively located on both sides of the partition 502, and the two compartments 503 are respectively communicated with the inside of the two fixed tubes 12, and the tube walls of the two compartments 503 are opened with communication ports. The two connecting ports 504 are symmetrically arranged with the partition plate 502 as the axis of symmetry, and the two connecting ports 503 can be controlled to be connected with the opening at one end of the intake pipe 1 through the connecting ports 504 respectively by moving the inner tube 501 horizontally, and the positions of the two connecting ports 504 are specifically arranged that when the connecting port 504 on the tube wall of one of the connecting ports 503 is connected with the opening at one end of the intake pipe 1, the connecting port 504 of the other connecting port 503 is staggered with the opening of the intake pipe 1, therefore, the fixed tube 12 is switched by moving the inner tube 501.

[0024] Therefore, by arranging a filter assembly 2 inside the air intake pipe 1, and setting the filter assembly 2 to an active state, when one of the compartments 503 is connected to the air intake pipe 1 to allow air to enter, when the filter assembly 2 is blocked, the filter assembly 2 will move due to changes in air pressure, and then the filter assembly 2 will drive the inner tube 501 to move in the same direction, so that the connecting port 504 of this compartment 503 is staggered with the opening at one end of the air intake pipe 1, and the connecting port 504 of the other compartment 503 is connected with the opening at one end of the air intake pipe 1, and then the filter assembly 2 of the other compartment 503 is switched to perform air purification, so that the filter assembly 2 can be switched in time to avoid affecting the flying catkin filtration.

[0025] In addition, considering that in actual operation, when the filter assembly 2 moves, the inner tube 501 will be driven to move synchronously, and the connecting port 504 will move synchronously at this time, which will cause the connecting port 504 to gradually reduce the connecting area with the opening at one end of the intake pipe 1, which will affect the movement of the inner tube 501 and the switching of the filter assembly 2, and there may be a situation where the two connecting ports 504 overlap and are connected to the intake pipe 1. Therefore, in this embodiment, a positioning member 6 is provided, and the positioning member 6 is used to ensure that the inner tube 501 moves immediately only when the filter assembly 2 moves to the position specified by the positioning member 6, thereby switching the compartment 503.

[0026] Specifically, Figures 2 - 6As shown, the filtering component 2 includes a moving ring 201, a cylinder body 202, a filter plate 203 and a triggering member 204. Among them, the moving ring 201 is arranged inside the compartment 503, and the outer circumferential outer wall of the moving ring 201 is in sliding sealing fit with the inner wall of the compartment 503. A cylinder body 202 is fixedly arranged on the moving ring 201 towards the nozzle 4, and the outer diameter of the cylinder body 202 is smaller than the inner diameter of the inner tube 501. There is a gap between the outer circumferential outer wall of the cylinder body 202 and the inner wall of the inner tube 501, and the inner diameter of the cylinder body 202 is the same as that of the inner diameter of the moving ring 201. A filter plate 203 is installed on the inner ring at one end of the cylinder body 202, and the triggering member 204 is arranged on one side of the moving ring 201 towards the nozzle 4. The triggering member 204 is used to unlock the positioning member 6.

[0027] It should be noted that the filter plate 203 is located between one end of the inner tube 501 and the air inlet end of the fixed tube 12. That is, after the air enters from the air inlet pipe 1 and enters the inner tube 501 through the communication port 504, it is filtered by the filter plate 203 at one end of the inner tube 501 and then enters the air box 13 through the fixed tube 12.

[0028] Through the above settings, when air enters at the communication port 504, the air will enter towards the fixed tube 12 on the same side, and the air will be filtered and purified by the filter plate 203. When the filter plate 203 is blocked, the filter plate 203 will move towards the nozzle 4 due to the air pressure change, causing the moving ring 201 to move synchronously. With long-term use, the blocked area of the filter plate 203 becomes larger, and the suction force on the filter plate 203 becomes larger. Therefore, the filter plate 203 will gradually move towards the nozzle 4 and gradually approach the nozzle 4. Here, the connection between the inner tube 501 and the connecting tube 3 is locked and limited by the positioning member 6. The filter plate 203 moves gradually due to the change in suction force, and the inner tube 501 remains stationary. Therefore, the communication between the communication port 504 and the air inlet pipe 1 will also remain connected. Since the moving distance of the filter plate 203 is proportional to the blocked area of the filter plate 203, in other words, the more severely the filter plate 203 is blocked, the longer the moving distance of the filter plate 203. Therefore, the positioning member 6 can be set at a limited position so that when the filter plate 203 needs to be replaced due to large-area blockage, the filter plate 203 can move to the corresponding position and unlock the positioning member 6 through the triggering member 204, unlocking the connection lock between the inner tube 501 and the connecting tube 3, and the inner tube 501 moves immediately through the triggering member 204, thereby switching the filtering component 2.

[0029] Specifically, the positioning member 6 includes a positioning ring 601, a telescopic insertion rod 602, and a jack 603. Among them, the positioning ring 601 is fixedly arranged at one end of the inner tube 501 and is concentric with the inner tube 501. The outer circumferential outer wall of the positioning ring 601 fits and slides with the inner wall of the connecting pipe 3. The inner diameter of the positioning ring 601 is smaller than the inner diameter of the inner tube 501. A telescopic insertion rod 602 is movably arranged inside the positioning ring 601 along its radial direction. Correspondingly, a jack 603 is arranged at a position corresponding to the telescopic insertion rod 602 on the inner wall of the connecting pipe 3. One end of the telescopic insertion rod 602 is movably inserted into the jack 603, thereby limiting the inner tube 501, so that the inner tube 501 can be limited inside the connecting pipe 3 through the insertion and cooperation of the telescopic insertion rod 602 and the jack 603 and cannot move horizontally. The trigger member 204 is set to separate the telescopic insertion rod 602 from the jack 603 after being triggered.

[0030] It should be noted that at least two telescopic insertion rods 602 are arranged inside the positioning ring 601. Correspondingly, the number of jacks 603 is the same as that of the telescopic insertion rods 602, and the telescopic insertion rods 602 are arranged in a circular array, so as to limit the inner tube 501 more stably through the cooperation of the telescopic insertion rods 602 and the jacks 603.

[0031] More specifically, the telescopic insertion rod 602 is composed of a rod body 621 slidably inserted into the positioning ring 601 and a first spring 622. Among them, a telescopic hole 623 for the rod body 621 to move is radially opened inside the positioning ring 601. The telescopic hole 623 penetrates the outer circumferential outer wall of the positioning ring 601. One end of the rod body 621 passes through the outer wall of the positioning ring 601 through the telescopic hole 623 and extends to the outside of the positioning ring 601 and is inserted into the jack 603. In addition, a through slot 7 is opened at the other end of the telescopic hole 623. The through slot 7 penetrates both end faces of the positioning ring 601, and the telescopic hole 623 is also communicated with the through slot 7. One end of the rod body 621 extends into the through slot 7. A first spring 622 is sleeved on the outer wall of the rod body 621. A pressure plate 624 is also fixedly sleeved on the outer wall of the rod body 621. One end of the first spring 622 contacts the pressure plate 624, and the other end contacts the inner wall of one end of the telescopic hole 623. The first spring 622 is used to rebound the rod body 621 towards the inside of the through slot 7.

[0032] It should be noted that when the first spring 622 is in a released state, one end of the rod body 621 extends into the through slot 7, and the other end of the rod body 621 contracts and separates from the jack 603.

[0033] Such as Figures 2 - 6As shown, the trigger member 204 includes an insertion strip 241, a second spring 242 and a clearance groove 243, wherein one end of the insertion strip 241 is fixedly connected to the movable ring 201, and the other end of the insertion strip 241 penetrates the positioning ring 601 along the axial direction of the positioning ring 601, and passes through the insertion slot 7 to extend to the other side of the positioning ring 601, and the insertion strip 241 and the positioning ring 601 are movably plugged and matched at the penetration point, and the end of the insertion rod body 621 located inside the insertion slot 7 is located above the insertion strip 241, and the second spring 242 is sleeved on the outside of the insertion strip 241, and the second spring 242 Located between the positioning ring 601 and the movable ring 201, the insertion strip 241 has a concave side facing the insertion rod body 621 to form a clearance groove 243. The side wall of the clearance groove 243 is an inclined surface for guiding, and the depth of the clearance groove 243 is configured so that when the insertion rod body 621 and the clearance groove 243 are on the same vertical axis, the insertion rod body 621 moves downward due to the rebound of the spring 242. When one end of the insertion rod body 621 contacts the bottom wall of the clearance groove 243, the end of the insertion rod body 621 located inside the insertion hole 603 is separated from the insertion hole 603 and contracts to the inside of the telescopic hole 623.

[0034] Through the above arrangement, the position of the paving groove 243 can be configured so that when the filter plate 203 is blocked in a large area, the filter plate 203 moves toward the pipe opening 4, and the filter plate 203 drives the insertion strip 241 to move synchronously. When a large area of ​​blockage occurs and the filter plate 203 needs to be removed, the paving groove 243 is moved to the bottom of the insertion rod body 621. Therefore, the spring 622 can rebound to make the insertion rod body 621 contract and separate from the insertion hole 603, so that the inner tube 501 and the connecting rod 501 can be separated. The connection limit of the connecting pipe 3 is released, and when the filter plate 203 moves before, it will compress the spring 242, and then after the limit is released by the insertion rod body 621, the positioning ring 601 will be moved toward the blocked end pipe port 4 through the rebound of the spring 242, and then the inner tube 501 will be driven to move synchronously, so that the connecting port 504 of the other side compartment 503 is connected with the opening at one end of the air inlet pipe 1, and then the staff can clean and block the filter plate 203 without stopping the machine, and collect the flying catkins.

[0035] It should be noted that when the filter plate 203 is blocked over a large area and before it is completely blocked, that is, when the filter plate 203 can still circulate air, the insertion strip 241 moves to align the clearance groove 243 with the insertion rod body 621, as shown in FIG. Figure 7 As shown, the outer wall of the inner tube 501 and the inner wall of the connecting tube 3 can be limited by the limiting strip 8, so that the inner tube 501 can only move laterally inside the connecting tube 3 but cannot rotate in a circle.

[0036] In addition, if Figures 2 - 5As shown, a pressure column 11 is longitudinally slidably provided at one end of the insertion rod body 621 located inside the insertion slot 7, the bottom surface of the pressure column 11 is an arc surface, the pressure column 11 is located above the insertion strip 241, and the pressure column 11 is in contact with the outer wall of the insertion strip 241, and the pressure column 11 is connected to the insertion rod body 621 by an elastic member, and the pressure column 11 is rebounded toward the insertion strip 241 by the elastic member.

[0037] Therefore, during air purification, one of the compartments 503 in the inner tube 501 is connected to the inside of the air intake pipe 1 through the connecting port 504, and at this time, the connecting port 504 of the other compartment 503 is staggered with the opening of the air intake pipe 1. When the air enters the air intake pipe 1, the air enters the compartment 503 through the air intake pipe 1 and the connecting port 504. The air enters the bellows 13 through the fixed pipe 12 at one end of the compartment 503 and is discharged. At the same time, the air is filtered and purified by the filter plate 203 in the compartment 503. As the filter plate 203 is continuously filtered, it will be clogged. When the filter plate 203 is clogged, it will be affected by the air pressure. The filter plate 203 changes, which will cause the filter plate 203 to move toward the pipe opening 4. At this time, since the inner tube 501 and the connecting tube 3 are limited by the cooperation of the plug rod body 621 and the plug hole 603, the inner tube 501 cannot move. The movement of the filter plate 203 alone will drive the moving ring 201 to move, and the insertion strip 241 is inserted into the insertion slot 7 and moves. At the same time, the movement of the moving ring 201 will compress the spring 242 with the positioning ring 601. As the blocking area of ​​the filter plate 203 increases, the filter plate 203 moves a greater distance. Therefore, by setting the position of the give way slot 243, when the filter plate 203 is When the blockage reaches the upper limit, the insertion strip 241 moves to drive the clearance groove 243 to move to the inside of the insertion slot 7, and the clearance groove 243 is located below the pressure column 11 at one end of the insertion rod body 621. At this time, the insertion rod body 621 moves downward through the action of the spring 1 622, so that the insertion rod body 621 contracts, so that the end of the insertion rod body 621 located inside the insertion hole 603 is separated from the insertion hole 603 and contracts to the inside of the telescopic hole 623, thereby releasing the connection between the inner tube 501 and the connecting tube 3. After the insertion rod body 621 is no longer limited, the positioning ring 601 is moved by the action of the spring 242. It moves toward the pipe mouth 4, thereby driving the inner tube 501 to move synchronously so that after the inner tube 501 moves, the other compartment 503 is switched to be connected with the intake pipe 1, and then the filter assembly 2 is switched. It should be noted that when the positioning ring 601 moves, the plug rod body 621 on the positioning ring 601 will be blocked by the inner wall of the connecting tube 3, and rebounded by the elastic part between the pressure column 11 and the plug rod body 621. When the filter plate 203 of the other compartment 503 moves and switches, when the positioning ring 601 continues to move to the position of the socket 603, the plug rod body 621 rebounds and is reinserted into the socket 603 for limiting.

[0038] When the filter plate 203 moves to a limited position, that is, when the clearance groove 243 moves to the same axis as the insertion rod body 621, in order to limit the filter plate 203 body, as shown in FIG. Figures 2 - 6 , Figure 8 As shown, a limit assembly 9 is provided at one end of the cylinder 202; Specifically, the limiting assembly 9 includes a limiting ring 901, a slot 902, an air hole 903, a piston plate 904, a movable plate 905, a spring 906, a limiting rod 907, a limiting hole 908 and an air cylinder 909, wherein the limiting ring 901 is fixedly sleeved on the end of the cylinder 202, and the inside of the limiting ring 901 is provided with a slot 902 along its radial direction, and the slot 902 is provided with an air hole 903 toward the inner wall of the inner ring of the limiting ring 901, and the air hole 903 penetrates the inner wall of the cylinder 202, and correspondingly, the filter plate 203 is detachably mounted on the inner ring of the cylinder 202, and the outer circumferential outer wall of the filter plate 203 is in contact with the inner wall of the cylinder 202, and the opening of the air hole 903 penetrating the inner wall of the cylinder 202 is blocked by the outer circumferential outer wall of the filter plate 203, and the air hole 903 is communicated with the inside of the slot 902, and a piston plate 904 is slidably arranged inside the slot 902, and when the air hole 903 is inlet, the piston plate 904 is moved toward The piston plate 904 is provided with a movable plate 905 in the direction of the outer circumference of the limiting ring 901, a spring 906 is provided between the movable plate 905 and the piston plate 904, and a limiting rod 907 is fixedly provided on the other side of the movable plate 905, and the other end of the limiting rod 907 slides through the outer circumference of the limiting ring 901 and extends to the outside of the limiting ring 901, and a connecting pipe 3 is provided on the inner wall of the connecting pipe 3. The limiting hole 908 and the limiting rod 907 are plugged into and matched with the limiting hole 908. More specifically, when the filter plate 203 moves toward the pipe mouth 4 and the positioning groove 243 moves to be aligned with the plug rod body 621, the limiting ring 901 will move to the limiting hole 908, and the limiting rod 907 will be aligned with the limiting hole 908 and plugged into and matched with it, thereby limiting the position of the filter plate 203. In addition, the air cylinder 909 is provided to supply air to the air hole 903.

[0039] One end of the cylinder body 202 of the air pump 909 is fixedly connected to the limit ring 901. The draw rod of the air pump 909 is fixedly connected to the connecting pipe 3 through the connecting plate 10. The inside of the air pump 909 is communicated with the air hole 903 through the through hole. A one-way pipe for one-way air intake is also arranged at one end of the cylinder wall of the air pump 909, and the air intake direction is specifically from the outside towards the inside of the air pump 909. Therefore, through the above settings, when the filter plate 203 moves towards the pipe orifice 4, the air pump 909 supplies air towards the air hole 903, and the gas inside the air hole 903 will move the piston disc 904 upwards, thereby causing the spring three 906 to be compressed. When the limit ring 901 moves to the limit hole 908, the limit rod 907 will be inserted into the limit hole 908 under the action of the spring three 906 to limit the filter plate 203. Then, the spring two 242 rebounds to cause the positioning ring 601 and the inner pipe 501 to move for switching. When the filter plate 203 is taken out for disassembly, replacement or cleaning, one end of the air hole 903 is opened, and the air pressure inside the air hole 903 decreases. The piston disc 904 can be moved downwards by the weight of the limit disc and the limit rod 907. At this time, the limit rod 907 contracts into the slot hole 902, and the limit rod 907 is separated from the limit hole 908. Then, the filter plate 203 is reinstalled, and the filter plate 203 of the other compartment 503 moves to continue switching, so that the two compartments 503 can be automatically switched.

[0040] In this embodiment, as Figure 4 、 Figure 5 、 Figure 9As shown, guide plates 14 are respectively telescopically arranged at the front end and rear end inner walls of the give way groove 243, and the guide plates 14 are elastically telescopic through elastic members, and the guide plates 14 are telescopic along the width direction of the insertion strip 241, and the two guide plates 14 are at the top position of the give way groove 243, and a spacing is provided between the two guide plates 14 after they are extended, and the spacing is smaller than the diameter of the pressure column 11. It should be noted here that the length of the give way groove 243 along the length direction of the insertion strip 241 is greater than the diameter of the pressure column 11, so that when the insertion strip 241 moves with the movement of the filter plate, when the pressure column 11 is above the give way groove 243, it can be The two guide plates 14 above the clearance groove 243 are blocked, so that the pressure column 11 and the insertion rod body 621 will not move down temporarily, and the insertion rod body 621 will not separate from the insertion hole 603. In addition, the length of the guide plate 14 is set to be shorter than the length of the clearance groove 243, so that there is a spacing between the guide plate 14 and the side wall of one side of the clearance groove 243, and the length of this spacing is greater than the diameter of the pressure column 11. Then, as the insertion strip 241 continues to move, when the pressure column 11 is separated from the guide plate 14, the pressure column 11 will bounce down under the action of the spring 1 622, so that the pressure column 11 enters the inside of the clearance groove 243. At this time, the inner tube 501 is lost. After the limit of the insertion rod body 621 is removed, the inner tube 501 moves under the action of the spring 242. When the inner tube 501 moves, the pressure column 11 is located inside the yield groove 243, and the inner tube 501 will drive the positioning ring 601 to move synchronously. At this time, the cylinder 202 will be limited by the limit assembly 9, that is, the insertion strip 241 will remain stationary. Here, the side walls of one end of the two guide plates 14 are set as inclined surfaces, and one end of the two guide plates 14 is formed into an open shape. At this time, the pressure column 11 will move inside the yield groove 243, and the pressure column 11 will squeeze the guide plate 14 through the inclined edge of the guide plate 14 to make the guide plate 14 shrink, and the pressure column 11 will move inside the yield groove 243. The column 11 will move inside the makeshift groove 243. When the pressure column 11 moves inside the makeshift groove 243, the insertion rod body 621 will not extend out. After that, when the telescopic hole 623 on the positioning ring 601 is misaligned with the axial direction of the insertion hole 603, the pressure column 11 will rise again and move to above the insertion strip 241 through the side wall inclined surface guide of the makeshift groove 243, and the top of the insertion rod body 621 will contact the inner wall of the connecting tube 3. The spring 622 outside the insertion rod body 621 will be compressed. When the other side compartment 503 is switched later, the inner tube 501 moves in the opposite direction, and the insertion rod body 621 can be reinserted into the insertion hole 603 for positioning.

[0041] The principle of the present invention is as follows: when the present invention is working, one of the compartments 503 in the inner tube 501 is connected to the inside of the air intake pipe 1 through the connecting port 504, and at this time, the connecting port 504 of the other compartment 503 is staggered with the opening of the air intake pipe 1. When the air enters the air intake pipe 1, the air enters the compartment 503 through the air intake pipe 1 and the connecting port 504. The air is sucked into the bellows 13 through the fixed pipe 12 at one end of the compartment 503, and is filtered by the filter plate 203 inside the compartment 503. When the filter plate 203 is clogged with continuous filtering, the filter plate 203 will be blocked, and the filter plate 203 will move toward the pipe opening 4 due to the change of the internal and external pressure difference. At this time, since the inner tube 501 and the connecting tube 3 are limited by the cooperation of the plug rod body 621 and the plug hole 603, the inner tube 501 cannot move. The movement of the filter plate 203 alone will drive the moving ring 201 to move, and the insertion strip 241 will be inserted into the insertion slot 7 and move. At the same time, the moving ring 201 01 movement will compress spring 242 with positioning ring 601, and as the blocking area of ​​filter plate 203 increases, the moving distance of filter plate 203 will increase. Therefore, by setting the position of the giving way slot 243, when the blocking of filter plate 203 reaches the upper limit, the movement of the insertion strip 241 will drive the giving way slot 243 to move to the inside of the insertion slot 7, and the giving way slot 243 is located below the pressure column 11 at one end of the insertion rod body 621. At this time, the insertion rod body 621 moves downward through the action of spring 1 622, so that The plug rod body 621 is contracted, so that the end of the plug rod body 621 located inside the plug hole 603 is separated from the plug hole 603 and contracted to the inside of the connecting hole 1, thereby contacting the connection between the inner tube 501 and the connecting tube 3. After there is no limitation of the plug rod body 621, the positioning ring 601 is moved toward the pipe mouth 4 through the action of the spring 242, thereby driving the inner tube 501 to move synchronously. After the inner tube 501 moves, the other compartment 503 is switched to be connected with the intake pipe 1, thereby switching the filter component 2.
