Description

Technical Field

[0001] The present invention relates to the technical field of filtration, and specifically to a filtration device with adjustable precision online. Background Art

[0002] Suspended matter in liquid materials needs to be filtered using a filtration device. However, the existing filters still have the following deficiencies in use. The existing filters cannot change the filtration precision during the filtration process and must stop the machine, open the cover, and replace the filter element to change the filtration precision.

[0003] This filter is an invention of a technology that can arbitrarily adjust the filtration precision during online filtration, which changes the traditional method of replacing the filtration precision, saves the filter element and replacement costs. Therefore, a new design has been carried out for this situation. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A filtration device with adjustable precision online, including a filtration mechanism, a driving unit is fixedly connected to the top of the filtration mechanism, and a cleaning mechanism is fixedly connected to the bottom of the filtration mechanism; The filtering mechanism includes a filtering housing. At the top of the inner wall of the filtering housing, a screw shaft is rotatably connected. On one side of the outer part of the screw shaft, it is meshed and connected with the inner side of a driving unit. On the outer side of the screw shaft, an adjusting pressing plate is meshed and connected. On one side of the outer part of the adjusting pressing plate, a telescopic spring wire is fixedly connected. By controlling the rotation of the screw shaft through the driving unit, the rotation of the screw shaft controls the adjusting pressing plate to drive the telescopic spring wire to move up and down, thereby achieving the function of controlling the filtering precision, meeting different operation requirements, coping with the change of water quality, protecting subsequent equipment. By adjusting the filtering precision, impurities in the fluid can be effectively removed, which can protect subsequent equipment, extend its service life, reduce maintenance and replacement costs, change the traditional filtering precision replacement method, save filter elements and replacement costs. After the equipment operates for a long time, on the side of the telescopic spring wire away from the adjusting pressing plate, a lower leakage partition plate is fixedly connected. The telescopic spring wire adsorbs a large amount of impurities, which easily affects the subsequent filtering effect. By controlling the rotation of the screw shaft through the driving unit, the telescopic spring wire is fully stretched, and the impurities are flushed by the incoming liquid and discharged from the inclined pipe orifice at the bottom of the filtering housing after flushing. After flushing, filtering can continue, so as to keep the equipment running normally. On the edge of the outer part of the adjusting pressing plate, a fixed rail rod is slidably connected. The bottom of the fixed rail rod is fixedly connected with the top of the lower leakage partition plate. On the upper side of the outer part of the filtering housing, a feed pipe is fixedly connected. Materials enter the inside of the filtering housing from the feed pipe. The impurities in the materials rub against the telescopic spring wire, thereby achieving the filtering effect on the impurities, intercepting the impurities, and promoting the remaining materials to flow towards the bottom of the filtering housing. The filtered materials flow towards the discharge pipe, so as to facilitate discharge or participation in subsequent operations. At the bottom of the lower leakage partition plate, a rotating mechanism is fixedly connected. During the process that the materials flow towards the bottom of the equipment through the telescopic spring wire, the materials are precipitated at the bottom, thereby further improving the impurity stripping effect. Therefore, some impurity particles may adhere to the bottom of the inner wall of the filtering housing. On the side of the outer part of the filtering housing close to the rotating mechanism, a discharge pipe is fixedly connected.

[0005] Preferably, the rotating mechanism includes a fixed block. The top of the fixed block is fixedly connected with the bottom of the lower leakage partition plate. Inside the fixed block, a receiving shaft is rotatably connected. On the outer side of the receiving shaft, a rotating bracket is fixedly connected. The cleaning mechanism is connected to the receiving shaft in a lifting manner, thereby providing rotational kinetic energy for the rotating mechanism. By controlling the friction strip through the rotating bracket to rub against the bottom of the inner wall of the filtering housing, the function of cleaning the inner wall of the equipment is achieved. By friction, the adsorption of impurities is reduced, avoiding the excessive accumulation of impurities on the inner wall of the equipment after the equipment operates for a long time, which affects the internal liquid flow rate of the equipment and prevents the excessive impurities from affecting the subsequent liquid flow effect. On the side of the outer part of the rotating bracket away from the receiving shaft, a friction strip is fixedly connected.

[0006] Preferably, an arc-shaped incision is formed on the outer side of the friction strip. An arc-shaped rod is fixedly connected to the inner side of the arc-shaped incision. A friction block is slidably connected to the outer side of the arc-shaped rod and rotates during the friction between the friction block and impurities, so as to perform rotational friction, thereby reducing the friction pressure of the component, avoiding excessive friction on one side and causing excessive wear of the component, and thus extending the service life of the component. A block surface incision is formed on the outer side of the friction block. During the rotation of the friction strip, the friction block drives the inner wall of the equipment to be rubbed. By forming the block surface incision, the surface texture of the component is increased, thereby improving the friction effect on impurities and further improving the cleaning effect. The grooving increases the scraping effect on impurities, avoids caking of impurities after long-term accumulation, thereby increasing the cleaning difficulty, and increases the peeling effect on the caking. One side of the outside of the friction strip is fixedly connected with a wiping mechanism.

[0007] Preferably, the wiping mechanism includes a first connecting block. A wiping strip is fixedly connected to one side of the outside of the first connecting block. During the rotational friction of the friction block, the friction block is frictionally adapted to the wiping strip, and the component is cleaned by the wiping strip, so as to peel and clean the impurities on the surface of the component, prevent excessive adsorption of impurities, and thus affect the subsequent friction effect of the component, so as to clean the component and keep the component running normally. A second connecting block is fixedly connected to the side of the wiping strip away from the first connecting block.

[0008] Preferably, the cleaning mechanism includes a cleaning frame body. A connecting shaft is rotatably connected to the inner side of the cleaning frame body. The connecting shaft is rotated by a motor, and the connecting shaft drives the spraying mechanism to rotate. The inner wall bottom of the filter housing is sprayed and flushed by the spraying mechanism. The spraying and flushing range is increased by rotating spraying, and the spraying and flushing dead angle is reduced, so as to keep the surface of the impurities moist and avoid the drying and caking of the impurities, which increases the subsequent cleaning difficulty. A receiving plate is rotatably connected to the bottom of the connecting shaft. A motor is fixedly connected to the side of the receiving plate away from the cleaning frame body. The output end of the motor is fixedly connected to the bottom of the connecting shaft. A spraying mechanism is fixedly connected to the top of the connecting shaft. By matching the flushing with the rotating mechanism, the cleaning efficiency and cleaning quality are improved, the impurities on the inner wall of the equipment are reduced, the inside of the equipment is kept clean, the long-term accumulation of impurities is prevented, which easily affects the liquid flow effect, and secondly, the corrosion of the equipment by the impurities is prevented, so as to affect the service life of the equipment.

[0009] Preferably, an electric push rod is fixedly connected to the edge of the bottom of the cleaning frame body. The electric push rod controls the lifting of the connecting shaft, and the connecting shaft drives the spraying mechanism to lift, so as to increase the spraying range and improve the flushing effect of the component, and at the same time meet different operation requirements. The outside of the electric push rod away from the cleaning frame body is fixedly connected to the outside of the receiving plate. A docking mechanism is fixedly connected to the top of the spraying mechanism.

[0010] Preferably, the docking mechanism includes a receiving rod, and a cylindrical shell is slidably connected to the outside of the receiving rod. A spring strip is fixedly connected to the top of the inner wall of the cylindrical shell. When the electric push rod controls the docking mechanism to lift and dock with the receiving shaft, when the cylindrical shell is subjected to a reaction force from the component, the cylindrical shell squeezes and contracts the spring strip towards the receiving rod, thereby playing a role in shock absorption and buffering, reducing the docking pressure, avoiding excessive pushing pressure that may cause excessive collision of the components, preventing damage to the components, and thus maintaining the stability of the device. One side of the outside of the spring strip is fixedly connected to the outside of the receiving rod.

[0011] Preferably, an external connection end is fixedly connected to the side of the cylindrical shell away from the receiving rod, and the outside of the external connection end is inserted and connected to the inside of the receiving shaft. Promote the insertion connection between the external connection end and the inside of the receiving shaft. Then, when the motor controls the rotation of the connection shaft, it can drive the rotation mechanism to rotate, thereby realizing the scraping and flushing of the device.

[0012] Preferably, the spraying mechanism includes a spraying shell. A cylindrical notch is formed on the outside of the spraying shell. A fixing frame is fixedly connected to one side of the inner wall of the spraying shell close to the cylindrical notch. A rotating shaft is rotatably connected to the outside of the fixing frame. A paddle is fixedly connected to the middle of the outside of the rotating shaft. When water flows from the spraying shell towards the cylindrical notch and flushes the inside of the device, the water impacts the paddle, causing the paddle to drive the rotation of the rotating shaft. Connection brackets are fixedly connected to both ends of the outside of the rotating shaft. An adapter rod is fixedly connected between the opposite surfaces of the connection brackets. A friction column is fixedly connected to the outside of the adapter rod. The rotation of the rotating shaft drives the connection brackets, and the connection brackets control the friction column to rub against the inner wall of the cylindrical notch, thereby achieving the effect of cleaning the impurities on the inner wall of the component. On the one hand, it prevents the adsorption of impurities in the water flow, and on the other hand, the impurities in the liquid of the external device precipitate inside the component, avoiding the entry of external impurities into the pipeline and adsorption, preventing blockage of the water outlet, and thus maintaining the normal operation of the device.

[0013] The present invention provides a filtering device with adjustable precision online. It has the following beneficial effects: 1. The filter device with online adjustable precision is designed with a filtering mechanism. The material enters the filter housing from the feed pipe, and the impurities in the material rub against the telescopic spring wire to filter the impurities, intercept the impurities, and force the remaining materials to flow to the bottom of the filter housing. The filtered materials flow to the discharge pipe to facilitate discharge or subsequent operations. In the process of the material flowing to the bottom of the equipment through the telescopic spring wire, the material is precipitated at the bottom, thereby further improving the stripping effect of impurities. As a result, some impurity particles may adhere to the bottom of the inner wall of the filter housing. Secondly, the screw shaft is controlled to rotate by the driving unit, and the screw shaft rotates to control the adjustment plate to drive the telescopic spring wire. It can be lifted up and down to control the filtering accuracy, meet different operation requirements, cope with the change of water quality and protect the subsequent equipment. By adjusting the filtering accuracy, the impurities in the fluid can be effectively removed, which can protect the subsequent equipment, prolong its service life and reduce the maintenance and replacement cost. It has changed the traditional way of changing the filtering accuracy and saved the filter element and replacement cost. After the equipment has been in operation for a long time, the telescopic spring wire absorbs a large amount of impurities, which can easily affect the subsequent filtering effect. By driving the unit to control the rotation of the screw shaft, the telescopic spring wire is fully stretched, and the impurities are flushed by the incoming liquid. After flushing, they are discharged from the inclined pipe port at the bottom of the filter shell. After flushing, filtering can continue to keep the equipment running normally.

[0014] 2. The filtering device with online adjustable precision is designed with a rotating mechanism. The cleaning mechanism is connected to the receiving shaft by lifting, so as to provide rotational kinetic energy for the rotating mechanism. The friction strip is controlled by the rotating bracket to rub the bottom of the inner wall of the filter housing, so as to achieve the function of cleaning the inner wall of the equipment. Impurity adsorption is reduced by friction, and impurities are prevented from being accumulated too thickly on the inner wall of the equipment after the equipment is operated for a long time, thereby affecting the flow rate of liquid inside the equipment, and preventing excessive impurities from affecting the subsequent liquid flow effect. During the rotation of the friction strip, the friction block is driven to rub the inner wall of the equipment. By opening the block surface incision, the surface texture of the component is increased, thereby improving the friction effect on impurities and further improving the cleaning effect. The scraping effect on impurities is increased by grooving, and impurities are prevented from agglomerating after long-term accumulation, thereby increasing the difficulty of cleaning, and increasing the stripping effect of agglomerates. The friction block rotates during the friction between the friction block and the impurities, so as to perform rotational friction, thereby reducing the friction pressure of the component, avoiding excessive friction on one side, resulting in excessive wear of the component, and extending the service life of the component.

[0015] III. The filter device with adjustable precision online, through the design of the cleaning mechanism, controls the rotation of the connecting shaft through the motor, and the connecting shaft drives the spraying mechanism to rotate. The spraying mechanism sprays and flushes the bottom inner wall of the filter housing, increases the spraying and flushing range through rotating spraying, reduces the dead angle of spraying and flushing, so as to keep the surface of impurities wet, avoid the drying and caking of impurities and increase the subsequent cleaning difficulty. At the same time, it adapts to the flushing and rotating mechanism, improves the cleaning efficiency and quality, reduces the impurities on the inner wall of the equipment, keeps the inside of the equipment clean, prevents the long-term accumulation of impurities, which is likely to affect the liquid flow effect, and secondly prevents the corrosion of the equipment by impurities, thus affecting the service life of the equipment. The electric push rod controls the lifting of the connecting shaft, and the connecting shaft drives the spraying mechanism to lift, so as to increase the spraying range, improve the flushing effect of the components, and meet different operation requirements at the same time.

[0016] IV. The filter device with adjustable precision online, through the design of the docking mechanism, when the electric push rod controls the docking mechanism to lift and dock with the receiving shaft, when the cylindrical housing is affected by the reaction of the components, the cylindrical housing squeezes and contracts the spring strip against the receiving rod, so as to play a role of shock absorption and buffering, reduce the docking pressure, avoid excessive pushing pressure resulting in excessive collision of the components, prevent damage to the components, thus maintaining the stability of the equipment, promoting the insertion of the external end into the inner side of the receiving shaft, and then when the motor controls the rotation of the connecting shaft, it can drive the rotating mechanism to rotate, so as to realize the scraping and flushing of the equipment.

[0017] V. The filter device with adjustable precision online, through the design of the spraying mechanism, when the water flow flows from the spraying housing to the cylindrical notch and flushes and cleans the inside of the equipment, the water flow impacts the paddle, makes the paddle drive the rotating shaft to rotate, and the rotating shaft drives the connecting bracket to rotate. The connecting bracket controls the friction column to friction the inner wall of the cylindrical notch, so as to achieve the effect of cleaning the impurities on the inner wall of the components. On the one hand, it prevents the adsorption of impurities in the water flow, and on the other hand, the impurities in the liquid of the external equipment precipitate inside the components, avoiding the entry of external impurities into the pipeline and adsorption, preventing blockage of the water outlet, and thus keeping the equipment running normally.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The first embodiment, as Figures 1 to 4 As shown, the present invention provides a technical solution: a filtering device with online adjustable precision, comprising a filtering mechanism 1, a driving unit 3 is fixedly connected to the top of the filtering mechanism 1, and a cleaning mechanism 2 is fixedly connected to the bottom of the filtering mechanism 1; The filtering mechanism 1 includes a filtering housing 11. At the top of the inner wall of the filtering housing 11, a screw shaft 12 is rotatably connected. On one side of the outer part of the screw shaft 12, it is meshed and connected to the inner side of the driving unit 3. On the outer side of the screw shaft 12, an adjusting pressing plate 13 is meshed and connected. On one side of the outer part of the adjusting pressing plate 13, a telescopic spring wire 16 is fixedly connected. On the side of the telescopic spring wire 16 away from the adjusting pressing plate 13, a lower leakage partition plate 14 is fixedly connected. At the edge of the outer part of the adjusting pressing plate 13, a fixed rail rod 15 is slidably connected. The bottom of the fixed rail rod 15 is fixedly connected to the top of the lower leakage partition plate 14. On the upper side of the outer part of the filtering housing 11, a feed pipe 17 is fixedly connected. At the bottom of the lower leakage partition plate 14, a rotating mechanism 18 is fixedly connected. On one side of the outer part of the filtering housing 11 close to the rotating mechanism 18, a discharge pipe 19 is fixedly connected. Materials enter the inside of the filtering housing 11 from the feed pipe 17. The impurities in the materials rub against the telescopic spring wire 16, so as to achieve the filtering effect on the impurities, intercept the impurities, and promote the remaining materials to flow towards the bottom of the filtering housing 11. The filtered materials flow towards the discharge pipe 19, so as to facilitate the discharge or participation in subsequent operations. During the process that the materials flow towards the bottom of the equipment through the telescopic spring wire 16, the materials precipitate at the bottom, so as to further improve the stripping effect of the impurities. Therefore, some impurity particles may adhere to the bottom of the inner wall of the filtering housing 11. Secondly, the driving unit 3 is used to control the rotation of the screw shaft 12. The rotation of the screw shaft 12 controls the adjusting pressing plate 13 to drive the telescopic spring wire 16 to move up and down, so as to achieve the function of controlling the filtering accuracy, so as to meet different operation requirements, cope with the change of water quality, protect the subsequent equipment. By adjusting the filtering accuracy, impurities in the fluid can be effectively removed, the subsequent equipment can be protected, its service life can be extended, the maintenance and replacement costs can be reduced, the traditional filtering accuracy replacement method is changed, and the filter element and replacement costs are saved. When the equipment operates for a long time, the telescopic spring wire 16 adsorbs a large amount of impurities, which easily affects the subsequent filtering effect. The driving unit 3 is used to control the rotation of the screw shaft 12 to fully stretch the telescopic spring wire 16. The impurities are flushed by the incoming liquid and discharged from the inclined pipe orifice at the bottom of the filtering housing 11 after flushing. After flushing, the filtering can continue, so as to keep the equipment running normally.

[0022] The rotating mechanism 18 includes a fixed block 181. The top of the fixed block 181 is fixedly connected to the bottom of the lower leakage partition 14. A receiving shaft 189 is rotatably connected inside the fixed block 181. A rotating bracket 182 is fixedly connected to the outside of the receiving shaft 189. A friction strip 183 is fixedly connected to one side of the rotating bracket 182 away from the receiving shaft 189. The cleaning mechanism 2 is connected to the receiving shaft 189 in a lifting manner to provide rotational kinetic energy for the rotating mechanism 18. The friction strip 183 is controlled by the rotating bracket 182 to rub against the bottom inner wall of the filter housing 11, so as to clean the inner wall of the device. By friction, the adsorption of impurities is reduced, and it is avoided that after the device operates for a long time, the impurities on the inner wall of the device accumulate too thickly, thereby affecting the liquid flow rate inside the device, and preventing too many impurities from affecting the subsequent liquid flow effect.

[0023] Second Embodiment. On the basis of the first embodiment, please refer to Figures 5 to 6 As shown, an arc-shaped notch 184 is formed on the outside of the friction strip 183. An arc-shaped rod 185 is fixedly connected to the inside of the arc-shaped notch 184. A friction block 186 is slidably connected to the outside of the arc-shaped rod 185. A block surface notch 187 is formed on the outside of the friction block 186. A wiping mechanism 188 is fixedly connected to one side of the friction strip 183. During the rotation of the friction strip 183, the friction block 186 is driven to rub against the inner wall of the device. By forming the block surface notch 187, the surface texture of the component is increased, so as to improve the friction effect on impurities and further improve the cleaning effect. By grooving, the scraping effect on impurities is increased, and it is avoided that the impurities agglomerate after long-term accumulation, thereby increasing the cleaning difficulty, and increasing the peeling effect on the agglomerates. During the friction between the friction block 186 and the impurities, rotation occurs for rotational friction, so as to reduce the friction pressure of the component and avoid excessive friction on one side, resulting in excessive wear of the component, thereby prolonging the service life of the component.

[0024] The wiping mechanism 188 includes a first connecting block 1881. A wiping strip 1883 is fixedly connected to one side of the first connecting block 1881. A second connecting block 1882 is fixedly connected to the side of the wiping strip 1883 away from the first connecting block 1881. During the rotational friction of the friction block 186, the friction block 186 is frictionally adapted to the wiping strip 1883. The component is cleaned by the wiping strip 1883, so as to strip and clean the impurities on the surface of the component, prevent excessive adsorption of impurities, and thus affect the subsequent friction effect of the component, so as to clean the component and keep the component running normally.

[0025] Third Embodiment. On the basis of the first and second embodiments, please refer to Figures 7 to 9As shown in the figure, the cleaning mechanism 2 includes a cleaning frame body 21. A connecting shaft 23 is rotatably connected to the inner side of the cleaning frame body 21. A receiving plate 27 is rotatably connected to the bottom of the connecting shaft 23. A motor 24 is fixedly connected to the outer side of the receiving plate 27 away from the cleaning frame body 21. The output end of the motor 24 is fixedly connected to the bottom of the connecting shaft 23. A spraying mechanism 26 is fixedly connected to the top of the connecting shaft 23. The motor 24 controls the rotation of the connecting shaft 23, and the connecting shaft 23 drives the spraying mechanism 26 to rotate. The inner wall bottom of the filter housing 11 is sprayed and washed by the spraying mechanism 26. By rotating the spraying, the spraying and washing range is increased, and the spraying and washing dead angles are reduced, so as to keep the surface of the impurities wet, avoid the drying and caking of the impurities, increase the subsequent cleaning difficulty, and at the same time, through the flushing and matching with the rotating mechanism 18, the cleaning efficiency and cleaning quality are improved, the impurities on the inner wall of the equipment are reduced, the inside of the equipment is kept clean, the long-term accumulation of impurities is prevented, which is likely to affect the liquid flow effect, and secondly, the corrosion of the equipment by the impurities is prevented, thus affecting the service life of the equipment.

[0026] An electric push rod 22 is fixedly connected to the edge of the bottom of the cleaning frame body 21. The outer side of the electric push rod 22 away from the cleaning frame body 21 is fixedly connected to the outer side of the receiving plate 27. A docking mechanism 25 is fixedly connected to the top of the spraying mechanism 26. The electric push rod 22 controls the lifting of the connecting shaft 23, and the connecting shaft 23 drives the spraying mechanism 26 to lift, so as to increase the spraying range, improve the flushing effect of the components, and at the same time meet different operation requirements.

[0027] The docking mechanism 25 includes a receiving rod 254. A cylindrical shell 252 is slidably connected to the outer side of the receiving rod 254. A spring strip 253 is fixedly connected to the top of the inner wall of the cylindrical shell 252. One side of the outer part of the spring strip 253 is fixedly connected to the outer side of the receiving rod 254. When the electric push rod 22 controls the docking mechanism 25 to lift and dock with the receiving shaft 189, when the cylindrical shell 252 is subjected to the reaction of the components, the cylindrical shell 252 is pressed against the receiving rod 254 to squeeze and contract the spring strip 253, so as to play a role of shock absorption and buffering, reduce the docking pressure, avoid excessive pushing pressure causing excessive collision of the components, prevent damage to the components, and thus maintain the stability of the equipment.

[0028] An external connection end 251 is fixedly connected to the outer side of the cylindrical shell 252 away from the receiving rod 254. The outer side of the external connection end 251 is inserted and connected to the inner side of the receiving shaft 189. Promote the insertion of the external connection end 251 and the inner side of the receiving shaft 189. Then, when the motor 24 controls the rotation of the connecting shaft 23, the rotating mechanism 18 can be driven to rotate, so as to realize the scraping and flushing of the equipment.

[0029] The spraying mechanism 26 includes a spraying housing 261. A cylindrical notch 262 is formed on the outer side of the spraying housing 261. A fixing frame 263 is fixedly connected to one side of the inner wall of the spraying housing 261 near the cylindrical notch 262. A rotating shaft 264 is rotatably connected to the outer side of the fixing frame 263. A paddle 265 is fixedly connected to the middle of the outer part of the rotating shaft 264. Connecting brackets 266 are fixedly connected to both ends of the outer part of the rotating shaft 264. A connecting rod 267 is fixedly connected between the opposite surfaces of the connecting brackets 266. A friction column 268 is fixedly connected to the outer side of the connecting rod 267. When water flows from the spraying housing 261 to the cylindrical notch 262 and flushes and cleans the inside of the device, the water impacts the paddle 265, causing the paddle 265 to drive the rotating shaft 264 to rotate. The rotation of the rotating shaft 264 drives the connecting brackets 266, and the connecting brackets 266 control the friction column 268 to rub against the inner wall of the cylindrical notch 262, thereby achieving the effect of cleaning impurities on the inner wall of the component. On the one hand, it prevents the adsorption of impurities in the water flow, and on the other hand, it prevents the precipitation of impurities in the liquid of external equipment inside the component, avoiding the entry of external impurities into the pipeline and adsorption, and preventing blockage of the water outlet, so as to keep the device running normally.

[0030] During use, the liquid enters the inside of the filtering housing 11 from the feed pipe 17. During the flow of the liquid inside the filtering housing 11, it comes into contact with the telescopic spring wires 16. The telescopic spring wires 16 intercept and filter the impurities in the liquid. The filtered liquid precipitates at the bottom inside the filtering housing 11, and the impurities are further retained at the bottom of the filtering housing 11 by precipitation, thereby improving the filtering effect. The precipitated liquid is discharged outward from the discharge pipe 19 or is convenient for subsequent treatment. The driving unit 3 controls the rotation of the screw shaft 12, and the screw shaft 12 controls the lifting of the adjusting pressing plate 13. During the lifting of the adjusting pressing plate 13, it controls the telescopic spring wires 16 to expand and contract, thereby achieving the effect of adjusting the filtering accuracy, so as to meet different working requirements, optimize the filtering efficiency and cost. By adjusting the accuracy online, an optimal balance point can be found on the premise of ensuring the filtering effect, improving the filtering efficiency and reducing the cost. When the telescopic spring wires 16 are used for a long time for filtering, a large amount of impurities adhere to the surface of the component, which easily leads to a reduction in the filtering effect of the component. Therefore, the device needs to be cleaned regularly. The adjusting pressing plate 13 controls the telescopic spring wires 16 to lift and stretch, thereby increasing the distance between the telescopic spring wires 16. When cleaning the device, the water flow flushes the telescopic spring wires 16, thereby improving the impurity peeling effect and the cleaning effect, and facilitating the subsequent continuous operation of the component. The cleaning water flow is discharged from the inclined pipe at the bottom of the filtering housing 11.

[0031] After the device has been operating for a long time, a large amount of impurity particles are likely to accumulate at the bottom of the inner wall of the filter housing 11. During the water flow flushing process, after the water flow impacts the telescopic spring wire 16, the scouring force on the impurities at the bottom of the filter housing 11 is likely to be insufficient, resulting in the accumulation of impurities inside the device. The cleaning mechanism 2 controls the lifting of the connecting shaft 23 through the electric push rod 22, so that the docking mechanism 25 is inserted into the inner side of the receiving shaft 189 inside the rotating mechanism 18. When the motor 24 controls the rotation of the connecting shaft 23, the rotating mechanism 18 can be driven to rotate, and at the same time, the spraying mechanism 26 is driven to perform rotary spraying and scouring on the bottom of the inner wall of the device. By means of rotary spraying, the spraying and scouring range is increased, and the cleaning effect is further improved. The spraying mechanism 26 and the rotating mechanism 18 are adapted to operate, scouring while scraping and cleaning the bottom of the device, so as to improve the cleaning effect of the device, reduce impurity residues, keep the inside of the device clean, and thus extend the service life of the device. The impurities and water flow being cleaned are discharged through the pipe with an inclined bottom.
