Description

Technical Field

[0001] This invention relates to the field of industrial wastewater treatment technology, specifically to an anti-clogging suspended solids removal device for industrial wastewater treatment. Background Technology

[0002] Industrial wastewater commonly contains suspended solids (such as fibers, metal particles, sticky sludge, and colloidal impurities). If not removed promptly, this can lead to blockages and reduced efficiency in subsequent treatment units (such as biological treatment tanks, membrane modules, and pumps), and even system shutdowns. Suspended solids removal equipment, as a "pre-treatment" or "core separation" step in wastewater treatment, achieves efficient separation of suspended solids from water through physical interception, screening, centrifugation, and flotation technologies, laying the foundation for subsequent advanced treatment or achieving compliant discharge. Its core objectives are: suspended solids removal rate ≥85%, adaptability to different industrial wastewater characteristics (such as high concentration, high viscosity, and fine particle size), and ensuring continuous and stable system operation. It is widely used in industries such as chemical, textile, food, metallurgy, and papermaking.

[0003] The diversification of industrial production results in significant differences and complexities in the composition of suspended solids in wastewater from different industries. If suspended solids are not properly treated, they are prone to depositing on the inner walls of pipes, becoming entangled or stuck in the impeller of pumps, and forming physical blockages during wastewater transportation and treatment. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: an anti-clogging suspended solids removal device for industrial wastewater treatment, comprising:

[0005] A sewage tank, with transmission components fixedly connected to both sides of the sewage tank;

[0006] A cleaning component is used to clean suspended solids in a sewage tank. The bottom of the cleaning component is fixedly connected to the output end of the transmission component.

[0007] The cleaning component includes a connecting frame, the bottom of which is fixedly connected to the output end of the transmission component, a pump fixedly connected to the top of the connecting frame, a feeding mechanism fixedly connected to both sides of the pump, a collecting mechanism fixedly connected to the bottom of the connecting frame, and a scraping mechanism fixedly connected to the bottom of the collecting mechanism.

[0008] In the process of removing suspended solids from sewage tanks, by activating the transmission component, the output end of which drives the connecting frame to move back and forth along the surface of the sewage tank, gradually pushing the suspended solids accumulated on the surface of the sewage tank into the collection mechanism, thus completing the initial collection of surface suspended solids.

[0009] When the extraction pump is turned on, it will generate negative pressure suction through the suction port, which will drive the remaining floating suspended matter on the surface of the sewage tank into the feeding mechanism. Finally, the feeding mechanism will transport the suspended matter, completing the centralized feeding and transfer of the suspended matter.

[0010] The collection mechanism includes a collection frame, a connecting component fixedly connected to the top of the collection frame, guide plates fixedly connected to both sides of the top of the inner cavity of the collection frame, inclined plates fixedly connected to both sides of the bottom of the inner cavity of the collection frame, a driving component fixedly connected to both sides of the collection frame, a contact component fixedly connected to the output end of the driving component, and the bottom of the contact component slidably connected to the bottom of the inner cavity of the collection frame.

[0011] When the transmission component is activated, its power is transmitted to the connecting frame through the output end, which drives the connecting frame to move along the preset trajectory, thereby pulling the collection frame to move synchronously. The collection frame provides guidance for suspended matter to enter. Guide plates are provided on both sides of the top of its inner cavity to help guide the flow of suspended matter on the water surface. Inclined plates are installed on both sides of the bottom. By using the guiding effect of the inclined angle, the suspended matter and impurities floating on the surface of the sewage tank naturally slide into the inner side of the collection frame during the movement of the collection frame, completing the initial aggregation.

[0012] When a certain amount of suspended matter accumulates in the collection rack, the extraction pump is turned on: the extraction pump generates negative pressure suction when it runs, and the suspended matter inside the collection rack is sucked into the pump body through the connecting component. Then, the output end of the extraction pump delivers the suspended matter to the feeding mechanism on both sides, realizing the centralized transfer and feeding of suspended matter.

[0013] To avoid impurities remaining and affecting collection efficiency, the drive unit on both sides of the collection rack can be activated. The output end of the drive unit drives the contact component to move inside the collection rack. On the one hand, it pushes the accumulated impurities toward the connecting component, ensuring that the impurities are transported synchronously by the pump. On the other hand, the contact component can contact the bottom of the inner cavity of the collection rack to scrape off the deposited residual impurities and clean the bottom of the collection rack.

[0014] Preferably, the connecting assembly includes a connecting pipe, the side of which is fixedly connected to the inside of the collecting rack, the top of which is fixedly connected to the output end of the extraction pump, a bracket fixedly connected to the inside of the connecting pipe, a connecting shaft rotatably connected to the inside of the bracket, a guide vane fixedly connected to the top of the connecting shaft, rotating rods evenly arranged on the side of the connecting shaft, a transverse groove formed on the side of the rotating rods, and the side of the rotating rods fixedly connected to the inside of the connecting shaft.

[0015] Preferably, when the extraction pump is started, its output end generates negative pressure suction, which sucks the suspended solids and sewage collected inside the collection rack into the connecting pipe. A guide vane is installed on the top of the connecting shaft. When the sewage flows through the connecting pipe under the drive of the pump, the water flow will naturally drive the guide vane to rotate, thereby pulling the connecting shaft to rotate synchronously inside the connecting pipe. At the same time, a transverse groove is opened on the side of the rotating rod connected below the connecting shaft. As the rotating rod rotates with the connecting shaft, the transverse groove can fully contact the suspended solids that enter with the sewage. Through shearing and impact, large pieces and long strips of suspended solids are broken into small particles. The broken suspended solids can pass smoothly through the extraction pump with the sewage and finally enter the conveying pipe to complete the discharge.

[0016] Preferably, the contact assembly includes a contact frame, the bottom of which is slidably connected to the bottom of the inner cavity of the collection rack, the side of which is fixedly connected to the output end of the second drive component, a slide rod slidably connected to the inner side of the contact frame, a contact plate fixedly connected to the bottom of the slide rod, a first spring sleeved on the slide rod, the top of the first spring fixedly connected to the inner side of the contact frame, and the bottom of the first spring fixedly connected to the top of the contact plate.

[0017] Preferably, when the suspended matter in the collection rack is discharged in a concentrated manner, the drive unit 1 on both sides of the collection rack is activated simultaneously. The output end of the drive unit 1 will push the contact frame to move along the preset trajectory at the bottom of the inner cavity of the collection rack. When the contact frame moves, it will simultaneously drive the contact plate to slide tightly against the bottom of the collection rack, thereby scraping and cleaning the residual impurities deposited at the bottom.

[0018] Preferably, the scraping mechanism includes a movable frame, the top two sides of which are fixedly connected to the bottom of the collection frame, a driving component three is fixedly connected to the middle of the top of the movable frame, telescopic rods are fixedly connected to the bottom two sides of the bottom of the movable frame, the bottom of the telescopic rods is fixedly connected to the top of the cleaning frame, a movable shaft is fixedly connected to the output end of the driving component three, the bottom of the movable shaft is fixedly connected to the top of the cleaning frame, and a cleaning component is fixedly connected to the bottom of the movable shaft;

[0019] Preferably, the drive unit three is turned on first, and its output end drives the cleaning component to move smoothly downwards towards the bottom of the sewage tank through the moving shaft until the bottom of the cleaning component is completely attached to the bottom of the sewage tank cavity, ensuring that the cleaning component can fully contact the sludge at the bottom of the tank.

[0020] Preferably, the transmission component is then activated, which drives the connecting frame to move along a preset trajectory. The connecting frame then pulls the cleaning component to move synchronously through the moving shaft and the telescopic rods on both sides of the bottom of the cleaning component. During this process, the sludge scraping end of the cleaning component will exert a continuous scraping force on the sediment sludge accumulated at the bottom of the sewage tank, and completely scrape off the hardened or loose sludge.

[0021] Preferably, the cleaning assembly includes a cleaning frame, with round rods evenly arranged at the bottom of the cleaning frame, the top of the round rods slidably connected to the bottom of the cleaning frame, a scraper fixedly connected to the bottom of the round rods, both sides of the scraper being slidably connected to the inner side of the cleaning frame, and a second spring sleeved on the round rods, the top of the second spring being fixedly connected to the bottom of the cleaning frame, and the bottom of the second spring being fixedly connected to the top of the scraper.

[0022] Preferably, in the coordinated operation of cleaning impurities and collecting suspended solids at the bottom of the sewage tank, when the mobile frame moves synchronously with the collection frame, its driving force is stably transmitted to the cleaning frame through the telescopic rod and the moving shaft, causing the cleaning frame to move horizontally along the preset trajectory at the bottom of the sewage tank. The cleaning frame is rigidly connected to the scraper through the round rod at the bottom. During the movement, the round rod will pull the scraper to make close contact with the bottom of the sewage tank cavity. With the scraping force of the scraper, the deposited impurities accumulated at the bottom of the tank can be completely scraped off, creating conditions for the subsequent centralized discharge and transfer of impurities.

[0023] Preferably, the feeding mechanism includes a conveying pipe, one end of which is fixedly connected to the output end of the extraction pump, a second driving component is fixedly connected to the side of the conveying pipe, a spiral blade is rotatably connected to the inside of the conveying pipe, one end of the spiral blade is fixedly connected to the output end of the second driving component, a water pipe is fixedly connected to the inside of the conveying pipe, the other end of the water pipe is fixedly connected to the top of the inner cavity of the collection rack, a mesh plate is fixedly connected to the top of the water pipe, and a feeding pipe is fixedly connected to the side of the conveying pipe away from the water pipe.

[0024] This invention provides an anti-clogging suspended solids removal device for industrial wastewater treatment. It has the following beneficial effects:

[0025] 1. The anti-clogging suspended solids removal equipment for industrial wastewater treatment is equipped with a collection mechanism. The collection rack guides the entry of suspended solids. Guide plates are provided on both sides of the top of the inner cavity to help guide the flow of suspended solids on the water surface. Inclined plates are installed on both sides of the bottom. By using the guiding effect of the inclined angle, the suspended solids and impurities floating on the surface of the wastewater tank naturally slide into the inner side of the collection rack during the movement of the collection rack, thus completing the initial aggregation.

[0026] 2. This anti-clogging suspended solids removal equipment for industrial wastewater treatment is equipped with a connecting component. Through the active crushing action of the rotating rod and the horizontal groove, it avoids the problem of large pieces of suspended solids getting stuck in the connecting pipe and the pump impeller. The horizontal groove design increases the contact area between the rotating rod and the suspended solids, which can also crush viscous and fibrous suspended solids, adapting to the suspended solids characteristics of different types of industrial wastewater.

[0027] 3. This anti-clogging suspended solids removal equipment for industrial wastewater treatment is equipped with a contact component and a first spring for elastic buffering. This avoids the problems of scraping the inner wall of the collection rack and wear of the contact plate caused by hard contact in traditional rigid cleaning structures. The contact plate can adaptively adjust its fit under the action of the spring. Even if there are slight bumps or uneven accumulation of impurities at the bottom of the collection rack, the extension and contraction of the spring can ensure that the contact plate always scrapes away impurities, avoiding cleaning dead corners.

[0028] 4. This industrial wastewater treatment anti-clogging suspended solids removal equipment is equipped with a feeding mechanism. The squeezing and dewatering action of the spiral blades reduces the water content of suspended solids, thereby reducing energy consumption and costs for subsequent sludge dewatering and transportation. At the same time, it improves the feasibility of solid waste resource utilization. Through the screen filtration and feeding pipe return design, the separated water is guided back to the collection rack, realizing the "secondary utilization" of wastewater and reducing the industrial water replenishment demand. The small-diameter suspended solids after crushing, combined with the propulsion action of the spiral blades, can avoid the problem of "large suspended solids blocking the pipe" in traditional conveying. At the same time, the screen only allows water to pass through, preventing suspended solids from entering the feeding pipe and causing blockage.

[0029] 5. This anti-clogging suspended solids removal equipment for industrial wastewater treatment is equipped with a cleaning component and a second spring with elastic buffer design. It can adapt to the thickness and protrusion of impurities accumulated at the bottom of the pool, avoiding problems such as pool bottom wear and scraper breakage caused by the "hard scraping" of traditional rigid scrapers. The extension and contraction adjustment of the spring can ensure that the scraper always keeps in contact with the bottom of the pool, avoiding impurity residue caused by contact gaps.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-2 This invention provides a technical solution: an anti-clogging suspended solids removal device for industrial wastewater treatment, comprising:

[0042] Sewage tank 1, with transmission components 2 fixedly connected to both sides of sewage tank 1;

[0043] The cleaning component 3 is used to clean suspended solids in the sewage tank 1. The bottom of the cleaning component 3 is fixedly connected to the output end of the transmission component 2.

[0044] Please see Figures 1-3 The cleaning component 3 includes a connecting frame 31. The bottom of the connecting frame 31 is fixedly connected to the output end of the transmission component 2. A suction pump 32 is fixedly connected to the top of the connecting frame 31. A feeding mechanism 33 is fixedly connected to both sides of the suction pump 32. A collection mechanism 34 is fixedly connected to the bottom of the connecting frame 31. A scraping mechanism 35 is fixedly connected to the bottom of the collection mechanism 34.

[0045] In the process of removing suspended solids from sewage tank 1, by activating the transmission component 2, its output end will drive the connecting frame 31 to move back and forth along the liquid surface of sewage tank 1, gradually pushing the suspended solids accumulated on the surface of sewage tank 1 into the collection mechanism 34, thus completing the initial accumulation of surface suspended solids.

[0046] When the extraction pump 32 is turned on, it will generate negative pressure suction through the suction port, which will drive the remaining floating suspended matter on the surface of the sewage tank 1 into the feeding mechanism 33. Finally, the feeding mechanism 33 will transport the suspended matter, completing the centralized feeding and transfer of the suspended matter.

[0047] Please see Figures 1-4 The collection mechanism 34 includes a collection rack 341, a connecting component 342 fixedly connected to the top of the collection rack 341, guide plates 344 fixedly connected to both sides of the top of the inner cavity of the collection rack 341, inclined plates 343 fixedly connected to both sides of the bottom of the inner cavity of the collection rack 341, a drive component 345 fixedly connected to both sides of the collection rack 341, a contact component 346 fixedly connected to the output end of the drive component 345, and the bottom of the contact component 346 slidably connected to the bottom of the inner cavity of the collection rack 341.

[0048] When the transmission component 2 is activated, its power is transmitted to the connecting frame 31 through the output end, which drives the connecting frame 31 to move along the preset trajectory, thereby pulling the collection frame 341 to move synchronously. The collection frame 341 provides guidance for the entry of suspended matter. Guide plates 344 are provided on both sides of the top of its inner cavity to help guide the flow of suspended matter on the water surface. Inclined plates 343 are installed on both sides of the bottom. By using the guiding effect of the inclined angle, the suspended matter and impurities floating on the water surface of the sewage tank 1 naturally slide into the inner side of the collection frame 341 during the movement of the collection frame 341, completing the initial aggregation.

[0049] When a certain amount of suspended matter accumulates in the collection rack 341, the extraction pump 32 is turned on: when the extraction pump 32 is running, it generates negative pressure suction, which draws the suspended matter inside the collection rack 341 into the pump body through the connecting component 342, and then the output end of the extraction pump 32 delivers the suspended matter to the feeding mechanism 33 on both sides, realizing the centralized transfer and feeding of suspended matter.

[0050] To avoid impurities affecting collection efficiency, the drive components 345 on both sides of the collection rack 341 can be opened. The output end of the drive component 345 drives the contact component 346 to move inside the collection rack 341. On the one hand, it pushes the accumulated impurities toward the connecting component 342, ensuring that the impurities are synchronously transported by the extraction pump 32. On the other hand, the contact component 346 can contact the bottom of the inner cavity of the collection rack 341 to scrape off the deposited residual impurities and clean the bottom of the collection rack 341.

[0051] Please see Figures 1-5The connecting assembly 342 includes a connecting pipe 3421. The side of the connecting pipe 3421 is fixedly connected to the inside of the collecting rack 341. The top of the connecting pipe 3421 is fixedly connected to the output end of the extraction pump 32. A bracket 3422 is fixedly connected to the inside of the connecting pipe 3421. A connecting shaft 3423 is rotatably connected to the inside of the bracket 3422. A guide vane 3425 is fixedly connected to the top of the connecting shaft 3423. Rotating rods 3424 are evenly arranged on the side of the connecting shaft 3423. A transverse groove is opened on the side of the rotating rods 3424. The side of the rotating rods 3424 is fixedly connected to the inside of the connecting shaft 3423.

[0052] When the extraction pump 32 is started, its output end generates negative pressure suction, which sucks the suspended solids and sewage collected inside the collection rack 341 into the connecting pipe 3421. A guide vane 3425 is installed on the top of the connecting shaft 3423. When the sewage flows through the connecting pipe 3421 under the drive of the pump, the water flow will naturally drive the guide vane 3425 to rotate, thereby pulling the connecting shaft 3423 to rotate synchronously inside the connecting pipe 3421. At the same time, a transverse groove is opened on the side of the rotating rod 3424 connected below the connecting shaft 3423. As the rotating rod 3424 rotates with the connecting shaft 3423, the transverse groove can fully contact the suspended solids that enter with the sewage. Through shearing and impact, large pieces and long strips of suspended solids are broken into small particles. The broken suspended solids can pass smoothly through the extraction pump 32 with the sewage and finally enter the conveying pipe 331 to complete the discharge.

[0053] Please see Figures 1-6 The contact component 346 includes a contact frame 3461. The bottom of the contact frame 3461 is slidably connected to the bottom of the inner cavity of the collection rack 341. The side of the contact frame 3461 is fixedly connected to the output end of the drive component 332. A slide rod 3462 is slidably connected to the inner side of the contact frame 3461. A contact plate 3463 is fixedly connected to the bottom of the slide rod 3462. A first spring 3464 is sleeved on the slide rod 3462. The top of the first spring 3464 is fixedly connected to the inner side of the contact frame 3461. The bottom of the first spring 3464 is fixedly connected to the top of the contact plate 3463.

[0054] When the suspended matter in the collection rack 341 is discharged in a concentrated manner, the drive unit 345 on both sides of the collection rack 341 is activated simultaneously. The output end of the drive unit 345 will push the contact frame 3461 to move along the preset trajectory at the bottom of the inner cavity of the collection rack 341. When the contact frame 3461 moves, it will simultaneously drive the contact plate 3463 to slide close to the bottom of the collection rack 341, thereby scraping and cleaning the residual impurities deposited at the bottom.

[0055] To prevent the contact plate 3463 from hard contacting the bottom of the collection rack 341 and causing scratch damage, a first spring 3464 is provided at the connection between the slide rod 3462 and the contact frame 3461. When the contact plate 3463 encounters thick impurities or protruding foreign objects during the cleaning process, the contact pressure between the contact plate 3463 and the impurities will gradually increase. When the pressure exceeds the initial tension of the first spring 3464, the first spring 3464 will be passively stretched, and then the slide rod 3462 will drive the contact plate 3463 to slide and retract towards the inside of the contact frame 3461. The contact pressure between the contact plate 3463 and the bottom of the collection rack 341 can be adjusted in real time to avoid scratches on the inner wall of the collection rack 341 or deformation of the contact plate 3463 caused by rigid collision.

[0056] Please see Figures 1-7 The scraping mechanism 35 includes a movable frame 351. The top two sides of the movable frame 351 are fixedly connected to the bottom of the collection rack 341. A drive component 352 is fixedly connected to the middle of the top of the movable frame 351. Telescopic rods 353 are fixedly connected to the bottom two sides of the movable frame 351. The bottom of the telescopic rods 353 is fixedly connected to the top of the cleaning rack 3551. A movable shaft 354 is fixedly connected to the output end of the drive component 352. The bottom of the movable shaft 354 is fixedly connected to the top of the cleaning rack 3551. A cleaning component 355 is fixedly connected to the bottom of the movable shaft 354.

[0057] First, turn on the drive unit 352. Its output end drives the cleaning component 355 to move smoothly downwards towards the bottom of the sewage tank 1 through the moving shaft 354 until the bottom of the cleaning component 355 is completely attached to the bottom of the inner cavity of the sewage tank 1, ensuring that the cleaning component 355 can fully contact the sludge at the bottom of the tank.

[0058] Then the transmission component 2 is activated, which drives the connecting frame 31 to move along the preset trajectory. The connecting frame 31 then pulls the cleaning component 355 to move synchronously through the moving shaft 354 and the telescopic rods 353 on both sides of the bottom of the cleaning component 355. During this process, the sludge scraping end of the cleaning component 355 will generate a continuous scraping force on the sediment sludge accumulated at the bottom of the inner cavity of the sewage tank 1, and completely scrape off the hardened or loose sludge.

[0059] Please see Figures 1-8 The cleaning assembly 355 includes a cleaning frame 3551. Round rods 3552 are evenly arranged at the bottom of the cleaning frame 3551. The top of the round rods 3552 is slidably connected to the bottom of the cleaning frame 3551. A scraper 3553 is fixedly connected to the bottom of the round rods 3552. Both sides of the scraper 3553 are slidably connected to the inner side of the cleaning frame 3551. A second spring 3554 is sleeved on the round rods 3552. The top of the second spring 3554 is fixedly connected to the bottom of the cleaning frame 3551. The bottom of the second spring 3554 is fixedly connected to the top of the scraper 3553.

[0060] In the coordinated operation of cleaning impurities and collecting suspended solids at the bottom of sewage tank 1, when the mobile frame 351 moves synchronously with the collection frame 341, its driving force is stably transmitted to the cleaning frame 3551 through the telescopic rod 353 and the moving shaft 354, causing the cleaning frame 3551 to move horizontally along the preset trajectory at the bottom of sewage tank 1. The cleaning frame 3551 is rigidly connected to the scraper 3553 through the round rod 3552 at the bottom. During the movement, the round rod 3552 will pull the scraper 3553 to make close contact with the bottom of the inner cavity of sewage tank 1. With the help of the scraping force of the scraper 3553, the sediment accumulated at the bottom of the tank can be completely scraped off, creating conditions for the subsequent centralized discharge and transfer of impurities.

[0061] To avoid damage caused by hard contact between the scraper 3553 and the bottom of the tank or by the accumulation of impurities, a second spring 3554 is installed at the connection between the round rod 3552 and the cleaning frame 3551. When the scraper 3553 encounters a thick layer of impurities or protruding foreign objects during its movement, and the squeezing force between the scraper 3553 and the impurities exceeds the initial tensile force of the second spring 3554, the second spring 3554 will automatically retract. This will cause the scraper 3553 to move adaptively towards the inside of the cleaning frame 3551 via the round rod 3552, thereby adjusting the contact pressure between the scraper 3553 and the bottom of the tank in real time. This will prevent the bottom of the sewage tank 1 from being scratched by rigid collisions, or the scraper 3553 from being deformed or broken.

[0062] Please see Figures 1-9 The feeding mechanism 33 includes a conveying pipe 331. One end of the conveying pipe 331 is fixedly connected to the output end of the extraction pump 32. A second driving component 332 is fixedly connected to the side of the conveying pipe 331. A spiral blade 333 is rotatably connected to the inside of the conveying pipe 331. One end of the spiral blade 333 is fixedly connected to the output end of the second driving component 332. A water pipe 334 is fixedly connected to the inside of the conveying pipe 331. The other end of the water pipe 334 is fixedly connected to the top of the inner cavity of the collection rack 341. A mesh plate 336 is fixedly connected to the top of the water pipe 334. A feeding pipe 335 is fixedly connected to the side of the conveying pipe 331 away from the water pipe 334.

[0063] Small-diameter suspended solids, after being crushed by the rotating rod 3424, will enter the conveying pipe 331 along with the wastewater through the extraction pump 32. When the drive unit 332 is turned on, its output end will drive the spiral blade 333 inside the conveying pipe 331 to rotate at a constant speed. On the one hand, the spiral propulsion force continuously pushes the suspended solids in the pipe towards the discharge end, realizing directional feeding and avoiding the deposition of suspended solids in the conveying pipe 331. On the other hand, the tight fit between the spiral blade 333 and the inner wall of the conveying pipe 331 forms a squeezing force, generating uniform squeezing force on the suspended solids, squeezing out the free water they carry, and completing the preliminary dewatering treatment.

[0064] To achieve water-slag separation and resource recovery, a feed pipe 335 is pre-installed on the side of the conveying pipe 331, and a mesh plate 336 is installed at the connection between the feed pipe 335 and the conveying pipe 331. The aperture is matched to the particle size of the suspended solids after crushing, allowing only water to pass through. The original sewage that enters the conveying pipe 331 with the suspended solids, as well as the water squeezed out by the spiral blade 333, will seep into the feed pipe 335 through the mesh plate 336 and eventually flow back to the collection rack 341 to participate in the suspended solids collection process again. The suspended solids after being squeezed and dewatered are propelled by the spiral blade 333 from the discharge end of the conveying pipe 331 into the subsequent processing unit corresponding to the feed pipe 335, completing the centralized discharge of the dewatered suspended solids.

[0065] Specific workflow:

[0066] When removing suspended solids in sewage tank 1, the transmission component 2 must be started first. After the transmission component 2 is running, it will transmit power to the cleaning component 3 through a transmission structure such as a screw, and drive it to move back and forth along the inner side of sewage tank 1. During this process, the cleaning component 3 can collect the sludge deposited in the tank, floating fiber impurities and other suspended solids, thereby completing the directional removal of suspended solids in sewage tank 1.
