[0017] The beneficial effects of the present application are as follows:

[0018] 1. The white water tower with slurry recycling function, when the shaft cylinder rotates, the shaft cylinder drives the rotating plate to rotate, the rotating plate extrudes the gas collection hose through the extrusion roller, so that one end of the gas collection hose inhales air and discharges the gas into the gas storage tank for collection, when the gas in the gas storage tank reaches a certain amount, the control system opens the electromagnetic valve, so that the gas is discharged into the white water through the aeration pipe, thereby realizing aeration, and the shaft cylinder can be cleaned through the aeration pipe, in the rotating process of the shaft cylinder, the fixedly connected rotating plate is driven to move synchronously, the rotating plate periodically compresses and releases the gas collection hose through the extrusion roller installed thereon, thereby realizing the reciprocating suction and exhaust action of the gas cavity inside the hose, when the extrusion roller presses down the gas collection hose, the internal volume decreases, a positive pressure is generated to deliver the gas to the gas storage tank for temporary storage, and in the release stage of the roller, the hose restores the deformation to form a local negative pressure, thereby inhaling air from the external environment, through the reciprocating action, the gas collection hose continuously supplies the gas storage tank with gas, when the gas pressure in the gas storage tank reaches a preset threshold value, the control system automatically opens the electrically controlled electromagnetic valve, so that the compressed gas is uniformly released to the liquid phase area inside the white water tower body through the aeration pipe, realizing the micro-porous aeration function, which avoids the gas loss caused by long-term aeration and is very beneficial to energy saving and emission reduction, the aeration process can also effectively disturb the white water, improve the filtration efficiency, and the airflow can also assist in cleaning the attachments on the surface of the porous ceramic filter plate and the shaft cylinder, thereby ensuring long-term stable operation of the system.

[0019] 2、The white water tower with slurry recovery function, when the shaft core drives the bearing disc and the porous ceramic filter plate to rotate to the upper side of the arc-shaped blocking plate, the arc-shaped blocking plate blocks the vacuum suction pipe, thereby cutting off the negative pressure path of the vacuum system in this area, which makes the filter cake adsorption area between the bearing disc and the porous ceramic filter plate lose the negative pressure maintaining force, creating conditions for the smooth peeling of the subsequent filter cake, at the same time, when the vacuum suction pipe on a certain bearing disc rotates into the corresponding position of the air supply groove, the compressed gas stored in the gas storage tank is transported to the air supply groove through the air supply pipe and further introduced into the internal cavity of the bearing disc, the high-pressure gas forms a reverse airflow between the bearing disc and the porous ceramic filter plate, which implements gas pressure backflushing on the filter medium from the inside to the outside, this process not only effectively removes the small particles and residual filter cake attached to the surface of the porous ceramic filter plate, improving its permeability, but also helps to accelerate the separation of the formed filter cake from the surface of the filter plate, improving the slurry recovery efficiency, ensuring the cleanliness and stability of the filter assembly in continuous operation, which is conducive to long-term and efficient operation of the system.

[0020] 3、The white water tower with slurry recovery function, when the shaft core drives the bearing disc and the porous ceramic filter plate to rotate to the upper side of the arc-shaped blocking plate, the arc-shaped blocking plate blocks the vacuum suction pipe, thereby cutting off the negative pressure path of the vacuum system in this area, which makes the filter cake adsorption area between the bearing disc and the porous ceramic filter plate lose the negative pressure maintaining force, creating conditions for the smooth peeling of the subsequent filter cake, at the same time, when the vacuum suction pipe on a certain bearing disc rotates into the corresponding position of the air supply groove, the compressed gas stored in the gas storage tank is transported to the air supply groove through the air supply pipe and further introduced into the internal cavity of the bearing disc, the high-pressure gas forms a reverse airflow between the bearing disc and the porous ceramic filter plate, which implements gas pressure backflushing on the filter medium from the inside to the outside, this process not only effectively removes the small particles and residual filter cake attached to the surface of the porous ceramic filter plate, improving its permeability, but also helps to accelerate the separation of the formed filter cake from the surface of the filter plate, improving the slurry recovery efficiency, ensuring the cleanliness and stability of the filter assembly in continuous operation, which is conducive to long-term and efficient operation of the system.

[0021] 4、The white water tower with slurry recovery function, in the process of rotating movement of the porous ceramic filter plate with the bearing disc, because the lifting slide rod moves in the guide rail through the guide rod, when the guide rod moves from the annular groove to the reciprocating groove, the guide rod drives the lifting slide rod to move outward, the lifting slide rod moves with the porous ceramic filter plate through the push-pull groove, thereby making the porous ceramic filter plate reciprocate, because the arc-shaped blocking plate has cut off the negative pressure supply of the vacuum suction pipe, combined with the reciprocating vibration effect of the porous ceramic filter plate itself, it can effectively promote the filter cake attached to its surface to fall off from the filter medium, improve the slurry recovery efficiency, in addition, during the high-pressure gas backflushing stage, after the high-pressure gas is introduced into the internal cavity of the bearing disc through the air supply pipe and the air supply groove, the porous ceramic filter plate moves towards the internal cavity of the bearing disc under the drive of the reciprocating mechanism, compressing the internal space and further enhancing the gas pressure, the high-pressure gas realizes deep cleaning of the residual particles and micro fibers in the filter hole through the capillary channels of the porous ceramic filter plate, thereby improving the cleaning efficiency and preventing the filter hole from being blocked, ensuring the long-term stable operation of the filter assembly.

[0048] As Figure 13As shown, in the white water treatment process, fibers, fillers and other substances are easy to adhere to the inner wall of the tower body, long-term accumulation will affect the equipment operation efficiency and even cause blockage, the bubble disturbance generated in the aeration process cannot make the tower body inner wall deposition impurities suspended in the white water again, the outer wall of the shaft cylinder 14 is provided with a reciprocating cleaning mechanism 6, the reciprocating cleaning mechanism 6 includes an eccentric driving disc 601 fixedly connected to the outer wall of the shaft cylinder 14, the outer wall of the eccentric driving disc 601 is rotatably connected with a connecting rod 602, one end of the connecting rod 602 away from the eccentric driving disc 601 is rotatably connected with a reciprocating driving rod 603, one end of the reciprocating driving rod 603 is fixedly connected with a lifting plate 604, the lifting plate 604 penetrates the top of the white water tower body 102 and extends to the inside, the bottom of the lifting plate 604 is rotatably connected with a push rod 605, one end of the push rod 605 away from the lifting plate 604 is rotatably connected with a cleaning roller 606, the inner wall of the white water tower body 102 is fixedly connected with an arc-shaped guide groove 607, the inner wall of the arc-shaped guide groove 607 is slidably connected with the end of the cleaning roller 606, the purpose of such arrangement is that when the shaft cylinder 14 synchronously drives the rotation of the eccentric driving disc 601 fixedly connected thereto, the eccentric driving disc 601 drives the reciprocating driving rod 603 and the lifting plate 604 connected thereto to perform periodic lifting action in the vertical direction, when the lifting plate 604 descends, it transmits power to the cleaning roller 606 through the push rod 605, so that the cleaning roller 606 moves along the trajectory defined by the arc-shaped guide groove 607, the cleaning roller 606 adheres to the inner wall surface of the white water tower body 102 under the constraint of the guide groove, effectively scraping off the impurities, fiber residues and sediments adhered to the inner side of the white water tower body 102.

[0049] Working principle of the white water tower with slurry recycling function: after starting the industrial motor 11, its power is transmitted to the shaft cylinder 14 through the chain wheel transmission system, driving the shaft cylinder 14 to rotate, the shaft cylinder 14 drives the bearing disc 201 connected therewith and the porous ceramic filter plate 23 installed thereon to rotate synchronously, so that the filter mechanism 2 is partially immersed in the white water, realizing initial contact, at the same time, the water pump 407 is started, the water pump 407 establishes a negative pressure environment in the inside of the shaft cylinder 14 through the drain pipe 406, the vacuum suction pipeline 21 separates the solid and liquid through the porous ceramic filter plate 23, the filtered filtrate enters the inside of the shaft cylinder 14 and is discharged from the system through the water pump 407, completing the water purification and recycling process, in this process, the fiber, filler and other slurry components suspended in the white water are intercepted on the surface of the porous ceramic filter plate 23, forming a preliminary filter cake layer, when the porous ceramic filter plate 23 rotates away from the liquid surface with the bearing disc 201, the vacuum pump 404 extracts gas from the upper space in the shaft cylinder 14 through the vacuum exhaust pipe 403, so as to form a local negative pressure area between the bearing disc 201 and the porous ceramic filter plate 23, due to the blockage of the microporous structure of the porous ceramic filter plate 23 by the slurry particles, the negative pressure further enhances the adhesion between the slurry and the filter medium, so that the filter cake is firmly adsorbed on the surface of the filter plate and moves together with it, providing preparation conditions for the subsequent scraping and recycling process;

[0050] When the shaft cylinder 14 rotates, the shaft cylinder 14 drives the rotating plate 301 to rotate, and the rotating plate 301 extrudes the gas collection hose 303 through the extrusion roller 302, so that one end of the gas collection hose 303 inhales gas and discharges the gas into the gas storage tank 305 for collection. When the gas in the gas storage tank 305 reaches a certain amount, the control system opens the electromagnetic valve 307, so that the gas is discharged into the white water through the aeration pipe 308, thereby realizing aeration, and the aeration pipe 308 can clean the shaft cylinder 14. During the rotation of the shaft cylinder 14, the fixedly connected rotating plate 301 is driven to move synchronously, and the extrusion roller 302 installed thereon periodically compresses and releases the gas collection hose 303, thereby realizing the reciprocating suction and exhaust action of the internal air cavity of the hose. When the extrusion roller 302 presses down the gas collection hose 303, the internal volume decreases, generating a positive pressure to deliver the gas to the gas storage tank 305 for temporary storage; and in the roller release stage, the hose restores the deformation to form a local negative pressure, thereby inhaling air from the external environment. Through the reciprocating action, the gas collection hose 303 continuously supplies gas to the gas storage tank 305. When the gas pressure in the gas storage tank 305 reaches a preset threshold, the control system automatically opens the electrically controlled electromagnetic valve 307, so that the compressed gas is uniformly released to the liquid phase area inside the white water tower 102 through the aeration pipe 308, realizing the micro-porous aeration function. The aeration process not only effectively disturbs the white water and improves the filtration efficiency, but also performs airflow auxiliary cleaning on the attachments on the surface of the porous ceramic filter plate 23 and the shaft cylinder 14, thereby ensuring long-term stable operation of the system.

[0051] When the shaft cylinder 14 drives the bearing disc 201 and the porous ceramic filter plate 23 to move above the arc-shaped blocking plate 501, the arc-shaped blocking plate 501 blocks the vacuum suction pipe 21, thereby releasing the negative pressure between the bearing disc 201 and the porous ceramic filter plate 23, facilitating the filter cake to separate from the porous ceramic filter plate 23. When the vacuum suction pipe 21 in a bearing disc 201 passes through the gas supply groove 502, the gas storage tank 305 discharges high-pressure gas into the gas supply groove 502 through the gas supply pipe 503. After the high-pressure gas enters between the bearing disc 201 and the porous ceramic filter plate 23, the gas performs backwashing on the porous ceramic filter plate 23 from the inside, thereby facilitating the cleaning of the porous ceramic filter plate 23, and facilitating the filter cake to be discharged.

[0052] When the shaft cylinder 14 drives the bearing disc 201 and the porous ceramic filter plate 23 to rotate above the arc-shaped blocking plate 501, the arc-shaped blocking plate 501 blocks the vacuum suction pipe 21, thereby cutting off the negative pressure passage of the vacuum system in this area, which makes the filter cake adsorption area between the bearing disc 201 and the porous ceramic filter plate 23 lose the negative pressure maintaining force, creating conditions for the smooth peeling of the subsequent filter cake. At the same time, when the vacuum suction pipe 21 on a certain bearing disc 201 rotates into the corresponding position of the gas supply groove 502, the compressed gas stored in the gas tank 305 is transported to the gas supply groove 502 through the gas supply pipe 503 and further introduced into the internal cavity of the bearing disc 201. The high-pressure gas forms a reverse airflow between the bearing disc 201 and the porous ceramic filter plate 23, which implements gas pressure backwashing on the filter medium from the inside to the outside. This process not only effectively removes small particles and residual filter cake attached to the surface of the porous ceramic filter plate 23, improving its permeability, but also helps to accelerate the separation of the formed filter cake from the filter plate surface, improving the slurry recovery efficiency, ensuring the cleanliness and stability of the filter assembly in continuous operation, and facilitating long-term and efficient operation of the system.

[0053] During the rotating movement of the porous ceramic filter plate 23 with the bearing disc 201, the lifting slide rod 202 moves in the guide rail 204 through the guide rod 203. When the guide rod 203 moves from the annular groove 205 to the reciprocating groove 206, the guide rod 203 drives the lifting slide rod 202 to move outward. The lifting slide rod 202 moves through the push-pull groove 25 and the porous ceramic filter plate 23, thereby making the porous ceramic filter plate 23 reciprocate. Since the arc-shaped blocking plate 501 has cut off the negative pressure supply of the vacuum suction pipe 21, combined with the reciprocating vibration effect of the porous ceramic filter plate 23 itself, it can effectively promote the filter cake attached to its surface to fall off from the filter medium, improving the slurry recovery efficiency. In addition, during the high-pressure gas backwashing stage, after the high-pressure gas is introduced into the internal cavity of the bearing disc 201 through the gas supply pipe 503 and the gas supply groove 502, the porous ceramic filter plate 23 moves towards the internal cavity of the bearing disc 201 under the drive of the reciprocating mechanism, compressing the internal space and further enhancing the gas pressure. The high-pressure gas realizes deep cleaning of the residual particles and microfibers in the filter hole through the capillary channels of the porous ceramic filter plate 23, thereby improving the cleaning efficiency and preventing the filter hole from being blocked, ensuring the long-term stable operation of the filter assembly.

[0054] The axis cylinder 14 drives the eccentric driving disc 601 fixedly connected therewith to rotate, the eccentric driving disc 601 drives the reciprocating driving rod 603 and the lifting plate 604 connected therewith to move up and down periodically in the vertical direction, when the lifting plate 604 moves downward, it transmits power to the cleaning roller 606 through the push rod 605, so that the cleaning roller 606 moves along the track defined by the arc-shaped guide groove 607. The cleaning roller 606 adheres to the inner wall surface of the white water tower 102 under the constraint of the guide groove, effectively scraping the impurities, fiber residues and deposits attached to the inner side of the white water tower 102. The impurities removed are transported to the area where the aeration mechanism 3 is located under the pushing action of the cleaning roller 606, at this time, the compressed gas released by the gas storage tank 305 enters the white water through the aeration pipe 308, forming uniform bubbles to disturb, so that the impurities and the white water are mixed and suspended again, thereby avoiding local blockage and deposition, keeping the internal fluid environment of the system clean and stable.
