Description

Technical Field

[0001] The present invention relates to the technical field of textile processing, and specifically to a textile dust collection device with a microparticle capture function. Background Art

[0002] At present, with the booming development of the textile industry, dust is generated in every link of the textile production process, from raw material opening, spinning, weaving to dyeing and finishing. These textile dusts have complex compositions, including natural fiber debris such as cotton, hemp, silk, and wool, chemical fiber particles, as well as impurities such as sand and metal microscraps mixed in the processing. If they cannot be efficiently collected and processed, a series of serious problems will occur.

[0003] Traditional methods generally rely solely on the airflow generated by a fan to push the dust to impact the filter screen to achieve the filtering purpose. However, the dust generation sources in the textile workshop are scattered and dynamically changing. When textile machinery operates at high speed, fibers and dust are scattered in a diffuse manner, and their movement trajectories are completely irregular. The static filter screen can only passively wait for the dust to hit it. A large number of dust microparticles have extremely small particle sizes and light weights, and are suspended and flow circuitously for a long time under the entrainment of the airflow, easily bypassing the pores of the filter screen, resulting in extremely low filtering efficiency. The particle size span of textile dust is extremely large, ranging from large flocculent fiber clusters visible to the naked eye to fine particles in the micron or even nanometer range. Traditional common filter screen type dust collection devices do not distinguish between microparticles and large particle size dust, and uniformly let them pass through the same filtering medium. Large particle size dust and fiber clusters are extremely easy to quickly accumulate on the surface of the filter screen, clog the pores, sharply increase the airflow resistance, and the fan is forced to increase the power to maintain the ventilation volume, resulting in a soaring energy consumption and a significant reduction in the equipment life.

[0004] As textile dust continuously accumulates on the filter screen, filter screen clogging is a pain point that traditional collection devices cannot avoid. Due to the high requirement for the continuity of the textile process, shutting down the equipment to clean the filter screen will disrupt the production rhythm and reduce production capacity. The few existing devices with cleaning functions mostly adopt the primitive methods of regularly manually removing the filter screen and flushing it with a high-pressure water gun, which not only consumes a large amount of manpower and time, but also easily damages the filter screen structure and shortens its service life. If the sewage after flushing with a high-pressure water gun is not properly disposed of, it will also cause secondary problems such as slippery workshop floors and water pollution. Summary of the Invention

[0005] The purpose of the present invention is to provide a textile dust collection device with a microparticle capture function to solve the problems raised in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] The described textile dust collection device with a particle capture function includes a vehicle body, a filtration unit, a capture unit, and a controller. The vehicle body is placed on a horizontal foundation. The filtration unit is installed on the surface of the vehicle body at the end away from the horizontal foundation. The filtration unit has the functions of self-cleaning and accelerating filtration. The filtration unit is fixedly connected to the capture unit. The capture unit is fixedly installed on the surface of the vehicle body at the end away from the horizontal foundation. The capture unit has the function of starting and stopping the self-cleaning of the filtration unit. The controller is fixedly installed on the vehicle body.

[0008] The vehicle body is used to install and fix the filtration unit, the capture unit, and the controller. The filtration unit is used to separate and filter large-particle dust and particulate dust. The capture unit is used to capture and collect particles. The controller is used to control the start and stop of the filtration unit and the capture unit. When the vehicle body is moving in the textile workshop, the air inside the workshop is adsorbed and filtered through the filtration unit, separating large dust and particles. After the particles enter the capture unit and are captured and collected, the purified air is re-discharged to the outside, thereby improving the environmental quality.

[0009] Furthermore, a handle with threads on its surface is provided on the vehicle body. Rollers are provided at one end of the vehicle body close to the horizontal foundation. An installation box is provided at the end of the vehicle body away from the horizontal foundation. An air inlet and an air outlet are provided on the installation box.

[0010] The threaded handle is to enable the staff to increase the friction with the handle and avoid slipping. The rollers facilitate the smooth movement of the vehicle body in the workshop and are convenient for collecting dust prevention throughout the workshop. The air inlet is used for inhaling the air in the workshop, and the air outlet is used for the purified air to re-flow into the workshop to improve the environmental quality.

[0011] Further, the filtering unit includes a fan, a filter plate, a first spring, a sliding column, a coil, a first conductive plate, a second conductive plate, an electric telescopic rod, a fixed block, a scraper, a memory spring and a spring expansion plate. The fan is installed at the air inlet of the installation box through a connecting rod. One end of the filter plate close to the horizontal base is fixedly connected to one end of the first spring, and the other end of the first spring is fixedly connected to a push block. The filter plate is slidably installed on the sliding column. A conductive ring is arranged at one end of the filter plate close to the horizontal base and is in sliding contact with the sliding column. The conductive ring on the filter plate is electrically connected to the memory spring. A magnetic block is arranged at one end of the filter plate away from the horizontal base. One end of the sliding column close to the horizontal base is fixedly connected to the push block, and the other end away from the horizontal base is fixedly installed on the first conductive plate. The coil is evenly wound around the sliding column. The first conductive plate is fixedly installed on the connecting plate. The second conductive plate is fixedly installed on the surface of the filter plate away from the horizontal base. The second conductive plate is sleeved on the outer surface of the sliding column. The first conductive plate is electrically connected to the electric telescopic rod. The fixed end of the electric telescopic rod is fixedly installed at one end of the sliding groove close to the horizontal base, and the telescopic end of the electric telescopic rod is fixedly connected to the fixed block. A round rod is arranged on the fixed block. The scraper is perpendicularly fixedly installed on the round rod of the fixed block. One end of the memory spring is fixedly connected to the scraper, and the other end is fixedly connected to the fixed end of the spring expansion plate. The fixed end of the spring expansion plate is rotatably installed on the round rod of the fixed block. In the vertical direction, both ends of the filter plate are fixedly connected to the upper and lower ends of the installation box through elastic filter cloth.

[0012] Further, the filtering unit further includes a first motor, a cleaning block, an electromagnet, a collection box, a pressure switch, a push block, a second spring, a connecting plate and a sliding groove. The fixed end of the first motor is fixedly installed on the upper surface of one end of the installation box close to the horizontal base, and the telescopic end of the first motor is fixedly connected to the cleaning block. The electromagnet is fixedly installed on the connecting plate. The electromagnet is located directly above the magnet on the filter plate. The collection box is fixedly installed at one end of the installation box close to the horizontal base. The pressure switch is fixedly installed in the collection box. The pressure switch is electrically connected to the electromagnet. The push block is slidably installed in the collection box. One end of the second spring is fixedly installed on the inner surface side wall of the collection box, and the other end is fixedly connected to the push block. The connecting plate is slidably installed on the inner surface of the other end of the installation box away from the horizontal base. The sliding groove is fixedly installed on the connecting plate. The push block is fixedly connected to the capturing unit.

[0013] During the process of the vehicle body moving in the workshop, the controller controls the fan to start, sucking the gas with textile dust in the workshop into the installation box. At this time, the controller controls the second motor to start, driving the rotating cylinder to rotate, so that the impact rod knocks and pushes the filter plate. During the process of the filter plate moving leftward and squeezing the second spring, the push block is driven to move leftward synchronously until the push block squeezes the pressing switch. At this time, the pressing switch starts to deliver the current of the controller to the electromagnet. The electromagnet is energized and presents a polarity opposite to that of the magnet block above the filter plate, thus attracting the magnet block to drive the filter plate to move upward along the sliding column. During the process of the filter plate stretching the first spring and moving upward, on the one hand, when the second conductive plate contacts the first conductive plate, the current of the controller is delivered to the electric telescopic rod through the second conductive plate and the first conductive plate, causing the electric telescopic rod to contract, thus driving the scraper on the fixed block and the spring telescopic plate to move downward synchronously, scraping the large-volume textile dust attached to the filter plate, making it fall into the collection box, avoiding the blockage of the filter holes of the filter plate and affecting the separation effect and efficiency of large-volume dust and particles. On the other hand, during the process of the filter plate moving upward along the sliding column, the conductive ring on the filter plate contacts the coil. At this time, the effective number of turns of the coil gradually decreases, the resistance gradually decreases, and the current delivered to the memory spring through the coil gradually increases. The memory spring heats up and contracts after receiving the current, thus driving the spring telescopic plate to rotate counterclockwise, pushing the gas and textile dust in the space on the left side of the filter plate to actively contact the filter plate, accelerating the separation and filtration of textile dust, and avoiding the situation of low passing efficiency when the air flow contacts the filter plate independently. When the spring telescopic plate contacts the bottom of the installation box, it gradually contracts under the action of pressure until the electric telescopic rod contracts to the limit position. The controller controls the first motor to start, thus driving the cleaning block to perform a contraction action in the front and rear directions, scraping the residual large flocculent fiber clusters on the spring telescopic plate and the scraper into the collection box, thus realizing the collection of large flocculents. When the filter plate does not contact the impact block, under the action of the self-restoring force of the second spring, it pushes the push block to drive the filter plate to move rightward. At this time, the pressing switch is no longer squeezed, and the electromagnet stops attracting the filter plate. Under the action of its own gravity, the filter plate moves downward along the sliding column and squeezes the first spring again. At this time, the second conductive plate and the first conductive plate are no longer in contact, and the electric telescopic rod pushes the fixed block upward, driving the scraper to move back to its original position. At this time, the effective number of turns of the coil gradually increases, and the current delivered to the memory spring gradually decreases. The memory spring gradually elongates and resets, driving the spring telescopic rod to rotate clockwise. After the spring telescopic plate is no longer under pressure, it elongates again to prepare for the next filtration.

[0014] Furthermore, the capture unit includes a second motor, a rotating drum, an impact rod, a discharge rod, a pole plate, a support rod, an extrusion block and a traction rope. The fixed end of the second motor is fixedly mounted on the upper surface of the installation box at one end away from the horizontal foundation. The output end of the second motor passes through the installation box and is fixedly connected to the rotating drum. A plurality of rectangular through holes are provided on the surface of the rotating drum. The impact rod is fixedly mounted on the outer surface of the rotating drum. The discharge rod is rotatably mounted on the support rod. The ratio of the length of the discharge rod extending into the interior of the rotating drum to the length of the discharge rod located outside the rotating drum is 1:8. The discharge rod is connected to the negative pole of the power supply in the controller. The pole plates are fixedly mounted on the inner surfaces of both sides of the installation box. The pole plates are connected to the positive pole of the power supply in the controller. The support rod is fixedly mounted on the outer surface of the rotating drum. There are multiple extrusion blocks, which are located inside the rotating drum. Multiple extrusion blocks are fixedly mounted on the traction rope, and the extrusion block is located above the discharge rod. One end of the traction rope is fixedly connected to the push block, and the other end is fixedly connected to the inner surface of the rotating drum at one end away from the horizontal foundation through a spring.

[0015] When the controller controls the second motor to start and drives the drum to rotate, on the one hand, the discharge rod is brought into contact with the particles passing through the filter plate. When the impact rod hits and pushes the filter plate to drive the push block to move to the left, the extrusion block in the drum is driven downward by the action of the traction rope, thereby squeezing the discharge rod on the support rod downward, so that the discharge rod on the outside of the drum rotates upward along the support rod. When the impact rod is not in contact with the filter plate, the filter plate moves to the right and resets under the action of the second spring. The traction rope pulls the extrusion block upward under the action of the spring in the drum, and pushes the discharge rod part in the drum again, so that the discharge rod part outside the drum rotates downward along the support rod, so that the discharge rod continues to swing up and down during the rotation process, increasing the chance of contact with particles in the air and improving the particle capture efficiency. At this time, the controller controls the discharge rod to release negative electricity to make the particles in the air negatively charged, and the positively charged electrode adsorbs and captures the negatively charged particles, thereby jointly improving the particle collection effect, so that the purified air is discharged from the air outlet of the installation box, thereby improving the air quality in the workshop.

[0016] Furthermore, an impact block is provided at one end of the impact rod away from the rotating drum, and the impact block is in the shape of a circle, a spherical or an arc plate.

[0017] In order to adapt to workshops with different concentrations of textile dust, the shape of the impact block is changed to change the contact time with the filter plate, thereby controlling the time for the electromagnet to attract the filter plate and changing the frequency of the filter plate jumping up and down. The filter screen that jumps up and down constantly changes its position, making it difficult for particles to accumulate in a fixed position. When the filter screen jumps, the dust and impurities on its surface will be affected by vibration and inertia, loosening and dropping the particles that have been adsorbed or accumulated on the filter surface, thereby achieving a self-cleaning effect.

[0018] Further, when the spring telescopic plate extends to the limit distance, it contacts the side wall of the installation box.

[0019] In order to enable the spring telescopic plate to swing during the telescopic process of the memory spring, the workshop dusty air adsorbed by the spring telescopic plate from the left space of the filter plate at the initial maximum distance is pushed by the spring telescopic plate to actively pass through the filter screen at one time, improving the filtration efficiency of textile dust.

[0020] Further, the end of the coil far from the horizontal base is the current input end.

[0021] In order to control the telescopic movement of the memory spring by changing the effective number of turns of the coil during the upward movement of the filter plate under the action of the electromagnet, thereby driving the spring telescopic plate to accelerate the contact between the dusty air on the left side of the filter plate and the filter plate that moves up and down, improving the filtration effect.

[0022] Further, the cleaning block is L-shaped.

[0023] When the spring telescopic plate is rectangular with the scraper under the action of the contraction of the memory spring, the L-shaped cleaning block fits the contact position of the spring telescopic plate, the scraper and the flocculent dust, so as to more accurately clean the flocculent matter and dust into the collection box.

[0024] Further, the initial state of the first spring is a compressed state.

[0025] When the first spring is initially compressed, the filter plate moves upward under the combined action of the electromagnet and the spring restoring force. When the filter plate descends, it receives the resistance of the first spring, so that the rising speed of the filter plate is greater than the descending speed. When the filter plate rises rapidly, the effective number of turns of the coil decreases rapidly, causing the memory spring to contract rapidly, improving the filtration efficiency of textile dust. When the filter plate descends slowly, the effective number of turns of the coil increases slowly, causing the memory spring to slowly extend, avoiding the gas and dust being lifted above the installation box when the spring telescopic plate resets, which affects the filtration effect.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. In the present invention, the impact rod pushes the filter plate to drive the push block to move leftward synchronously. When the pressing switch is activated to energize the electromagnet to attract the magnetic block and drive the filter plate to move upward, when the second conductive plate contacts the first conductive plate during the upward movement of the filter plate, the electric telescopic rod contracts, thereby driving the scraper on the fixed block and the spring telescopic plate to move downward synchronously to scrape off the large-volume textile dust attached to the filter plate, causing it to fall into the collection box, avoiding clogging of the filter holes of the filter plate and affecting the separation effect and efficiency of large-volume dust and particles. On the other hand, during the upward movement of the filter plate along the sliding column, the conductive ring on the filter plate contacts the coil. At this time, the effective number of turns of the coil gradually decreases, and the memory spring heats up and contracts after receiving an increasing current, causing the spring telescopic plate to rotate counterclockwise, pushing the gas and textile dust in the space on the left side of the filter plate to actively contact the filter plate, accelerating the separation and filtration of textile dust, and avoiding the situation where the air flow contacts the filter plate independently with low passing efficiency. When the spring telescopic plate contacts the bottom of the installation box, it gradually contracts under the action of pressure until the electric telescopic rod contracts to the limit position, and the controller controls the first motor to start, thereby pushing the cleaning block to scrape off the large flocculent fiber clusters remaining on the spring telescopic plate and the scraper into the collection box, thus realizing the collection of large flocculent substances.

[0028] 2. When the impact rod hits and pushes the filter plate to drive the push block to move leftward in the present invention, the extrusion block in the rotating cylinder is driven to move downward under the action of the traction rope, thereby squeezing the discharge rod on the support rod downward, causing the discharge rod to rotate upward along the support rod. When the impact rod does not contact the filter plate, at this time, the filter plate moves rightward and resets under the action of the second spring, and the traction rope pulls the extrusion block upward under the action of the spring in the rotating cylinder, causing the discharge rod to rotate downward along the support rod. During the rotation of the discharge rod, it continuously swings up and down, increasing the chance of contact with the particles in the air and improving the particle capture efficiency. At this time, the controller controls the discharge rod to release negative electricity to make the particles in the air carry negative charges, and the positively charged electrode plate adsorbs and captures the negatively charged particles, thereby jointly improving the collection effect of the particles and discharging the purified air from the air outlet of the installation box, thus improving the air quality in the workshop.

[0029] 3. In the present invention, by making the rising speed of the filter plate greater than the falling speed, when the filter plate rises rapidly, the effective number of turns of the coil decreases rapidly, causing the memory spring to contract rapidly, improving the filtration efficiency of textile dust. When the filter plate descends slowly, the effective number of turns of the coil increases slowly, causing the memory spring to elongate slowly, avoiding the situation where the gas and dust are lifted above the installation box when the spring telescopic plate resets, affecting the filtration effect.

[0030] 4. In order to adapt to workshops with different concentrations of textile dust, the present invention changes the shape of the impact block to change the contact time with the filter plate, thereby controlling the time for the electromagnet to attract the filter plate, and changing the frequency of the filter plate jumping up and down. At the same time, the filter screen that jumps up and down continuously changes its position, making it difficult for particles to accumulate in a fixed position. When the filter screen jumps, the dust and impurities on its surface will be affected by vibration and inertia, loosening and dropping the particles that have been adsorbed or accumulated on the filter screen surface, thereby achieving a self-cleaning effect.

The second conductive plate 27 is sleeved on the outer surface of the sliding column 24. The first conductive plate 26 is electrically connected to the electric telescopic rod 28. The fixed end of the electric telescopic rod 28 is fixedly installed at one end of the sliding groove 221 close to the horizontal base, and the telescopic end of the electric telescopic rod 28 is fixedly connected to the fixing block 29. A round rod is provided on the fixing block 29. The scraper 210 is perpendicularly fixedly installed on the round rod of the fixing block 29. One end of the memory spring 211 is fixedly connected to the scraper 210, and the other end is fixedly connected to the fixed end of the spring expansion plate 212. The fixed end of the spring expansion plate 212 is rotatably installed on the round rod of the fixing block 29. In the vertical direction, both ends of the filter plate 22 are fixedly connected to the upper and lower ends of the installation box 13 through elastic filter cloth.

[0050] As Figure 3 , 4As shown in Figures 5, 6, 7, 9, and 10, the filtering unit 2 further includes a first motor 213, a dirt cleaning block 214, an electromagnet 215, a collection box 216, a push switch 217, a push block 218, a second spring 219, a connecting plate 220, and a sliding groove 221. The fixed end of the first motor 213 is fixedly installed on the upper surface of the installation box 13 near one end of the horizontal base. The telescopic end of the first motor 213 is fixedly connected to the dirt cleaning block 214. The electromagnet 215 is fixedly installed on the connecting plate 220. The electromagnet 215 is located directly above the magnet on the filter plate 22. The collection box 216 is fixedly installed on the installation box 13 near one end of the horizontal base. The push switch 217 is fixedly installed in the collection box 216. The push switch 217 is electrically connected to the electromagnet 215. The push block 218 is slidably installed in the collection box 216. One end of the second spring 219 is fixedly installed on the inner surface side wall of the collection box 216, and the other end is fixedly connected to the push block 218.

The sliding groove 221 is fixedly installed on the connecting plate 220. The push block 218 is fixedly connected to the capture unit 3.

[0051] During the process of the vehicle body 1 moving in the workshop, the controller 4 controls the blower 21 to start, sucking the gas with textile dust in the workshop into the installation box 13. At this time, the controller 4 controls the second motor 31 to start, driving the rotating cylinder 32 to rotate, so that the impact rod 33 knocks and pushes the filter plate 22. During the process of the filter plate 22 moving leftward and squeezing the second spring 219, the push block 218 is driven to move leftward synchronously until the push block 218 squeezes the push button switch 217. At this time, the push button switch 217 starts to deliver the current of the controller 4 to the electromagnet 215. The electromagnet 215 is energized and presents a polarity opposite to that of the magnet block above the filter plate 22, thus attracting the magnet block and driving the filter plate 22 to move upward along the sliding column 24. During the process of the filter plate 22 moving upward by stretching the first spring 23, on the one hand, when the second conductive plate 27 contacts the first conductive plate 26, the current of the controller 4 is delivered to the electric telescopic rod 28 through the second conductive plate 27 and the first conductive plate 26, causing the electric telescopic rod 28 to contract, thereby driving the scraper 210 on the fixed block 29 and the spring telescopic plate 212 to move downward synchronously, scraping the large-volume textile dust attached to the filter plate 22, so that it falls into the collection box 216, avoiding the blockage of the filter holes of the filter plate 22 and affecting the separation effect and separation efficiency of large-volume dust and fine particles. On the other hand, during the process of the filter plate 22 moving upward along the sliding column 24, the conductive ring on the filter plate 22 contacts the coil 25. At this time, the effective number of turns of the coil 25 gradually decreases, the resistance gradually decreases, and the current delivered to the memory spring 211 through the coil 25 gradually increases. After receiving the current, the memory spring 211 heats up and contracts, thereby driving the spring telescopic plate 212 to rotate counterclockwise, pushing the gas and textile dust in the space on the left side of the filter plate 22 to actively contact the filter plate 22, accelerating the separation and filtration of textile dust, and avoiding the situation where the air flow contacts the filter plate 22 independently with low passing efficiency. When the spring telescopic plate 212 contacts the bottom of the installation box 13, it gradually contracts under the action of pressure until the electric telescopic rod 28 contracts to the limit position. The controller 4 controls the first motor 213 to start, thereby pushing the cleaning block 214 to perform a contraction action in the front and back directions, scraping the large flocculent fiber clusters remaining on the spring telescopic plate 212 and the scraper 210 into the collection box 216, thereby realizing the collection of large flocs. When the filter plate 22 does not contact the impact block, under the action of the self-restoring force of the second spring 219, the push block 218 is driven to drive the filter plate 22 to move rightward. At this time, the push button switch 217 is no longer squeezed, and the electromagnet 215 stops attracting the filter plate 22. Under the action of its own gravity, the filter plate 22 moves downward along the sliding column 24 and squeezes the first spring 23 again. At this time, the second conductive plate 27 and the first conductive plate 26 are no longer in contact, and the electric telescopic rod 28 pushes the fixed block 29 upward, driving the scraper 210 to move back to its original position. At this time, the effective number of turns of the coil 25 gradually increases, and the current delivered to the memory spring 211 gradually decreases. The memory spring 211 gradually elongates and returns to its original position, pushing the spring telescopic rod to rotate clockwise. After the spring telescopic plate 212 is not under pressure, it re-elongates to prepare for the next filtration.

[0052] As Figure 2 , 5 As shown in Figures 8, 11, etc., the capture unit 3 includes a second motor 31, a rotating cylinder 32, an impact rod 33, a discharge rod 34, a plate 35, a support rod 36, a pressing block 37 and a traction rope 38. The fixed end of the second motor 31 is fixedly installed on the upper surface of one end of the installation box 13 away from the horizontal base. The output end of the second motor 31 passes through the installation box 13 and is fixedly connected to the rotating cylinder 32. A plurality of rectangular through holes are formed on the surface of the rotating cylinder 32. The impact rod 33 is fixedly installed on the outer surface of the rotating cylinder 32. The discharge rod 34 is rotatably installed on the support rod 36. The ratio of the length of the discharge rod 34 extending into the rotating cylinder 32 to the length of the discharge rod 34 located outside the rotating cylinder 32 is 1:8. The discharge rod 34 is connected to the negative pole of the power supply in the controller 4. The plate 35 is fixedly installed on the inner surfaces of both sides of the installation box 13. The plate 35 is connected to the positive pole of the power supply in the controller 4. The support rod 36 is fixedly installed on the outer surface of the rotating cylinder 32. There are a plurality of pressing blocks 37. The pressing blocks 37 are located inside the rotating cylinder 32. The plurality of pressing blocks 37 are fixedly installed on the traction rope 38. The pressing blocks 37 are located above the discharge rod 34. One end of the traction rope 38 is fixedly connected to the push block 218, and the other end is fixedly connected to the inner surface of one end of the rotating cylinder 32 away from the horizontal base through a spring.

[0053] When the controller 4 controls the second motor 31 to start and drive the rotating cylinder 32 to rotate, on the one hand, it makes the discharge rod 34 contact with the particles passing through the filter plate 22. When the impact rod 33 impacts and pushes the filter plate 22 to drive the push block 218 to move leftward, under the action of the traction rope 38, it drives the pressing block 37 inside the rotating cylinder 32 to move downward, thereby pressing the discharge rod 34 on the support rod 36 downward, so that the discharge rod 34 outside the rotating cylinder 32 rotates upward along the support rod 36. When the impact rod 33 does not contact the filter plate 22, at this time, the filter plate 22 moves rightward and resets under the action of the second spring 219. The traction rope 38 pulls the pressing block 37 upward under the action of the spring inside the rotating cylinder 32, and again pushes a part of the discharge rod 34 inside the rotating cylinder 32, so that the part of the discharge rod 34 outside the rotating cylinder 32 rotates downward along the support rod 36. Thus, the discharge rod 34 continuously swings up and down during the rotation process, increasing the contact opportunity with the particles in the air and improving the particle capture efficiency. At this time, the controller 4 controls the discharge rod 34 to release negative electricity to make the particles in the air carry negative charges, and the positively charged plate 35 adsorbs and captures the negatively charged particles, thereby jointly improving the particle collection effect, enabling the purified air to be discharged from the air outlet of the installation box 13, and thus improving the air quality in the workshop.

[0054] As Figure 2 As shown in the figure, an impact block is provided at one end of the impact rod 33 away from the rotating cylinder 32. The shape of the impact block is circular, spherical or arc-shaped plate, etc.

[0055] In order to adapt to workshops under different concentrations of textile dust, by changing the shape of the impact block, the contact time with the filter plate 22 is changed, thereby controlling the time for the electromagnet 215 to attract the filter plate 22, changing the frequency of the up and down movement of the filter plate 22. The up and down moving filter screen continuously changes its position, making it difficult for particles to accumulate at a fixed position. When the filter screen moves up and down, on the one hand, the dust and impurities on its surface will be affected by vibration and inertial force, loosening and dropping the particles that have been adsorbed or accumulated on the surface of the filter screen, achieving the effect of self-cleaning.

[0056] As Figure 3 shown, when the spring expansion plate 212 extends to the limit distance, it contacts the side wall of the installation box 13.

[0057] In order to enable the spring expansion plate 212 to swing during the expansion and contraction of the memory spring 211, the air containing dust in the workshop that the spring expansion plate 212 adsorbs the space on the left side of the filter plate 22 from the initial maximum distance is, under the pushing action of the spring expansion plate 212, pushed to actively pass through the filter screen at one time, improving the filtration efficiency of textile dust.

[0058] As Figure 5 shown, the end of the coil 25 far from the horizontal base is the current input end.

[0059] In order to control the expansion and contraction of the memory spring 211 by changing the effective number of turns of the coil 25 during the upward movement of the filter plate 22 under the action of the electromagnet 215, thereby driving the spring expansion plate 212 to accelerate the contact between the dust-containing air on the left side of the filter plate 22 and the up and down moving filter plate 22, improving the filtration effect.

[0060] As Figure 4 shown, the cleaning block 214 is L-shaped.

[0061] When the spring expansion plate 212 forms a rectangle with the scraper 210 under the action of the contraction of the memory spring 211, the L-shaped cleaning block 214 fits the contact position of the spring expansion plate 212 with the scraper 210 and the flocculent dust, thereby more accurately cleaning the flocculent matter and dust into the collection box 216.

[0062] As Figure 10 shown, the first spring 23 is in a compressed state in the initial state.

[0063] When the first spring 23 is initially compressed, the filter plate 22 moves upward together under the action of the electromagnet 215 and the spring restoring force. When the filter plate 22 descends, it is resisted by the first spring 23, so that the rising speed of the filter plate 22 is greater than the descending speed. When the filter plate 22 rises rapidly, the effective number of turns of the coil 25 decreases rapidly, causing the memory spring 211 to contract rapidly, improving the filtration efficiency of textile dust. When the filter plate 22 descends slowly, the effective number of turns of the coil 25 increases slowly, causing the memory spring 211 to elongate slowly, preventing the gas and dust from being lifted above the installation box 13 when the spring expansion plate 212 resets, which affects the filtration effect.

[0064] The working principle of the present invention:

[0065] When the controller 4 controls the second motor 31 to start and drive the rotating cylinder 32 to rotate, on the one hand, it makes the discharge rod 34 contact with the particles passing through the filter plate 22. When the impact rod 33 impacts and pushes the filter plate 22 to drive the push block 218 to move leftward, under the action of the traction rope 38, it drives the extrusion block 37 in the rotating cylinder 32 to move downward, thereby squeezing the discharge rod 34 on the support rod 36 downward, causing the discharge rod 34 outside the rotating cylinder 32 to rotate upward along the support rod 36. When the impact rod 33 does not contact the filter plate 22, at this time, the filter plate 22 moves rightward and resets under the action of the second spring 219, and the traction rope 38 pulls the extrusion block 37 upward under the action of the spring in the rotating cylinder 32, pushing the part of the discharge rod 34 in the rotating cylinder 32 again, so that the part of the discharge rod 34 outside the rotating cylinder 32 rotates downward along the support rod 36, so that the discharge rod 34 continuously swings up and down during the rotation process, increasing the contact opportunity with the particles in the air and improving the particle capture efficiency. At this time, the controller 4 controls the discharge rod 34 to release negative electricity to make the particles in the air carry negative charges, and the positively charged electrode plate 35 adsorbs and captures the negatively charged particles, thereby jointly improving the particle collection effect, and making the purified air discharged from the air outlet of the installation box 13, thereby improving the air quality in the workshop.

[0066] During the process of the vehicle body 1 moving in the workshop, the controller 4 controls the blower 21 to start, sucking the gas with textile dust in the workshop into the installation box 13. At this time, the controller 4 controls the second motor 31 to start, driving the rotating cylinder 32 to rotate, so that the impact rod 33 knocks and pushes the filter plate 22. During the process of the filter plate 22 moving leftward to compress the second spring 219, it drives the push block 218 to move leftward synchronously until the push block 218 presses the push switch 217. At this time, the push switch 217 starts to deliver the current of the controller 4 to the electromagnet 215. The electromagnet 215 is energized and shows the opposite polarity to the magnet block above the filter plate 22, thus attracting the magnet block to drive the filter plate 22 to move upward along the sliding column 24. During the process of the filter plate 22 stretching the first spring 23 and moving upward, on the one hand, when the second conductive plate 27 contacts the first conductive plate 26, the current of the controller 4 is delivered to the electric telescopic rod 28 through the second conductive plate 27 and the first conductive plate 26, causing the electric telescopic rod 28 to contract, thus driving the scraper 210 on the fixed block 29 and the spring telescopic plate 212 to move downward synchronously to scrape off the large-volume textile dust attached to the filter plate 22, making it fall into the collection box 216, avoiding the blockage of the filter holes of the filter plate 22 and affecting the separation effect and separation efficiency of large-volume dust and particles. On the other hand, during the process of the filter plate 22 moving upward along the sliding column 24, the conductive ring on the filter plate 22 contacts the coil 25. At this time, the effective number of turns of the coil 25 gradually decreases, the resistance gradually decreases, and the current delivered to the memory spring 211 through the coil 25 gradually increases. After receiving the current, the memory spring 211 heats up and contracts, thus driving the spring telescopic plate 212 to rotate counterclockwise, pushing the gas and textile dust in the space on the left side of the filter plate 22 to actively contact the filter plate 22, accelerating the separation and filtration of textile dust, and avoiding the situation where the air flow contacts the filter plate 22 independently with low passing efficiency. When the spring telescopic plate 212 contacts the bottom of the installation box 13, it gradually contracts under the action of pressure until the electric telescopic rod 28 contracts to the limit position. The controller 4 controls the first motor 213 to start, thus pushing the cleaning block 214 to perform a contraction action in the front and back directions, scraping the large flocculent fiber clusters remaining on the spring telescopic plate 212 and the scraper 210 into the collection box 216, thus realizing the collection of large flocs. When the filter plate 22 does not contact the impact block, under the action of the self-restoring force of the second spring 219, it pushes the push block 218 to drive the filter plate 22 to move rightward. At this time, the push switch 217 is no longer pressed, and the electromagnet 215 stops attracting the filter plate 22. Under the action of its own gravity, the filter plate 22 moves downward along the sliding column 24 to compress the first spring 23 again. At this time, the second conductive plate 27 and the first conductive plate 26 are no longer in contact, and the electric telescopic rod 28 pushes the fixed block 29 upward to drive the scraper 210 to move back to its original position. At this time, the effective number of turns of the coil 25 gradually increases, and the current delivered to the memory spring 211 gradually decreases. The memory spring 211 gradually elongates and resets, pushing the spring telescopic rod to rotate clockwise. After the spring telescopic plate 212 is not under pressure, it re-elongates to prepare for the next filtration.
