Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically a solid-liquid separation treatment device based on the utilization of wastewater sludge. Background Technology

[0002] With the acceleration of urbanization and rapid industrial development, the amount of sewage treated is increasing day by day, and the amount of sewage sludge generated is also rising sharply. Sewage sludge not only contains a large number of harmful substances, such as heavy metals and pathogens, but also contains certain organic matter and nutrients. If sewage sludge is not treated properly, it will not only occupy a lot of land resources, but may also cause serious pollution to soil, water and air, threatening the ecological environment and human health. Among the many links in sewage sludge treatment and utilization, solid-liquid separation is one of the key steps. Through solid-liquid separation, the water content of sludge can be reduced, the volume and difficulty of subsequent treatment can be reduced, and water resources and valuable components can be recovered to achieve resource recycling. Among solid-liquid separation methods, the extrusion method is commonly used. However, when treating highly viscous sewage sludge, the traditional extrusion method has many problems. During the extrusion process, due to the high viscosity of the sludge, uneven separation occurs. The sludge closer to the filtration section has a better solid-liquid separation effect, while the sludge closer to the extrusion section, being relatively far from the filtration section, cannot fully contact the filtration section. This makes it difficult to effectively separate the solids and liquids in this part of the sludge, ultimately affecting the overall filtration effect. This poor filtration effect not only slows down the sewage sludge treatment speed, but may also leave the treated sludge with a lot of water or impurities, failing to achieve the ideal treatment results and hindering subsequent treatment or resource utilization. Summary of the Invention

[0003] To overcome the above-mentioned defects, the present invention provides a solid-liquid separation treatment device based on the utilization of sewage sludge. This solves the problem that in the traditional extrusion method, the solid-liquid separation is uneven due to the high viscosity of the sludge. The sludge closer to the filtration section has a better solid-liquid separation effect, while the sludge closer to the extrusion section is relatively far from the filtration section and cannot fully contact the filtration section, so the solid and liquid in this part of the sludge cannot be effectively separated, which ultimately affects the overall filtration effect.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a solid-liquid separation treatment device based on the utilization of sewage sludge, comprising a base, a separation box fixedly connected above the base, a first adjustment mechanism provided on the inner wall of one side of the separation box, the first adjustment mechanism comprising two first fixing plates fixedly installed on the inner wall of the separation box, a first support screw rotatably connected between the two first fixing plates, a first control motor fixedly installed on the top of the separation box, the output end of the first control motor penetrating the top of the separation box and connected to one end of the first support screw via one of the first fixing plates, four first limiting rods fixedly connected at the four corners between the two first fixing plates, and a squeezing structure provided on one side of the first adjustment mechanism.

The second adjustment mechanism includes a second fixing plate. There are two second fixing plates, which are fixedly installed on the inner wall of one side of the separation box. A second support screw is rotatably connected between the two second fixing plates at the center position. A second control motor is fixedly installed at the bottom of the separation box. The output end of the second control motor is connected to one end of the second support screw. Four second limit rods are fixedly installed at the four corners between the two second fixing plates.

[0006] As a further aspect of the present invention: a filter press mechanism is provided on one side of the second adjustment mechanism. The filter press mechanism includes a first filter plate. A housing is fixedly installed on one side of the first filter plate. A drive gear is rotatably connected to the inner wall of the housing. Two output gears are rotatably connected to the inner wall of the housing on both sides of the drive gear. Both output gears mesh with the drive gear. Two half gears are fixedly connected to the ends of the two output gears. The two half gears face the same direction. A reciprocating rod is slidably connected between the inner walls of the housing. The reciprocating rod passes through the top and bottom of the housing. The teeth of the two half gears mesh with the ring teeth of the reciprocating rod. A reciprocating plate is fixedly connected to the top of the reciprocating rod. The reciprocating plate slides between the inner walls of the first filter plate. The size of the first filter plate matches the size of the separation box. A second support screw passes through one side of the first filter plate and is threadedly connected to it. Four second limiting rods all pass through the first filter plate.

[0007] As a further embodiment of the present invention: the pressure plate and the first filter plate are respectively fixedly installed with two sealing shells at the threaded connection points with the first support screw and the second support screw. The sealing shells are hollow in design. The first support screw and the first limiting rod pass through the sealing shell connected to the pressure plate, and the second support screw and the second limiting rod pass through the sealing shell connected to the first filter plate.

[0008] As a further embodiment of the present invention: a filter box is fixedly installed above the base on one side of the separation box, and a suction pump is fixedly installed above the base between the separation box and the filter box. The input end of the suction pump is connected to the bottom of the separation box, and the output end of the suction pump is fixedly connected to a connecting pipe. The end of the connecting pipe away from the suction pump is connected to the top of the filter box.

[0009] As a further aspect of the present invention: two fixed supports are fixedly installed between the inner walls of the filter box, and a second filter plate is provided on one side of the filter box. The second filter plate passes through one side of the filter box and slides between the two fixed supports.

[0010] As a further embodiment of the present invention: a guide plate is fixedly installed at the bottom of the filter box, the guide plate is of inclined design, a drain outlet is provided near the bottom of the filter box, and the inclined direction of the guide plate is towards the drain outlet.

[0011] As a further aspect of the present invention: a sealing plate is rotatably connected to one side of the separation box via a hinge, and a telescopic rod is provided on one side of the sealing plate. Two connecting blocks are rotatably connected to both ends of the telescopic rod, one connecting block being connected to one side of the separation box and the other connecting block being connected to the center of the sealing plate. An injection port is provided on the outside of the separation box.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, by setting a first adjusting mechanism and a squeezing structure, when using the equipment, sewage sludge is injected into the space between the pressure plate and the first filter plate through the injection port. The first adjusting mechanism drives the pressure plate to press down, and the second adjusting mechanism drives the first filter plate to move upward. Solid-liquid separation is achieved through squeezing. During the solid-liquid separation process, the output motor drives the drive gear to rotate. The rotation of the drive gear drives the three driven gears meshing with it to rotate. The drive gear and the three driven gears respectively drive the four stirring screws to rotate. The stirring screws rotate below the pressure plate. The threaded design continuously conveys the sludge near the pressure plate to the first filter plate, continuously bringing the sludge that has not yet undergone solid-liquid separation closer to the first filter plate for solid-liquid separation. In this way, it can be ensured that the sludge that was originally difficult to reach the first filter plate under the pressure plate is effectively pushed towards the first filter plate, so that the sludge in the entire space has the opportunity to contact the first filter plate for solid-liquid separation. This improves the overall solid-liquid separation efficiency of the sludge and avoids the situation where the overall separation is incomplete because some sludge cannot reach the first filter plate, thereby improving the quality of sewage sludge treatment by the entire equipment.

[0013] 2. In this invention, by setting up a suction pump, a connecting pipe, and a filter box, the liquid after solid-liquid separation in the separation box passes through the first filter plate and accumulates at the bottom of the separation box under the action of gravity. The suction pump draws this liquid and transports it to the filter box through the connecting pipe. When this liquid enters the filter box, it first passes through the second filter plate, which performs secondary filtration on the liquid. Under the action of gravity, the liquid after secondary filtration accumulates at the bottom of the filter box and is discharged through the drain outlet. In this way, the purity of the liquid is improved, which is of great significance for subsequent liquid treatment or discharge. For example, if the liquid needs to be discharged into the natural environment, higher purity can reduce environmental pollution. If the liquid needs to be further recycled, purer liquid is also more conducive to subsequent processing steps, thus improving the practicality of the equipment. Attached Figure Description

[0015] The technical solution of this application will be further described in detail below with reference to specific embodiments.

[0016] like Figure 1-9 As shown, this invention provides a technical solution: a solid-liquid separation treatment device based on the utilization of sewage sludge, including a base 1, a separation tank 2 fixedly connected to the top of the base 1, and an injection port 18 on the outer side of the separation tank 2; a sealing plate 15 is rotatably connected to one side of the separation tank 2 via a hinge, and a telescopic rod 16 is provided on one side of the sealing plate 15. Two connecting blocks 17 are rotatably connected to both ends of the telescopic rod 16 via pins. One connecting block 17 is connected to one side of the separation tank 2, and the other connecting block 17 is connected to the center of the sealing plate 15. Through the cooperation between the telescopic rod 16 and the connecting blocks 17, the telescopic rod 16 extends and retracts by rotating on one side of the separation tank 2 via one connecting block 17, while simultaneously controlling the opening and closing degree of the sealing plate 15 precisely through the other connecting block 17. This ensures that the sealing plate 15 can be tightly closed during equipment operation to prevent material leakage, and can be easily opened when needed for maintenance, cleaning, or inspection of the interior of the separation tank 2.

[0017] The separation box 2 is provided with a first adjustment mechanism 3. The first adjustment mechanism 3 includes a first fixing plate 301. There are two first fixing plates 301, which are fixedly installed on the top and bottom inner walls of the separation box 2. A first support screw 302 is rotatably connected between the two first fixing plates 301. A first control motor 303 is fixedly installed on the top of the separation box 2. The output end of the first control motor 303 passes through the top of the separation box 2 and is connected to one end of one of the first fixing plates 301 and the first support screw 302.

[0018] The first adjusting mechanism 3 has a compression structure 4 on one side. The compression structure 4 includes a pressure plate 401, the size of which is adapted to the size of the separation box 2. The pressure plate 401 is attached to the inner wall of the separation box 2. The first support screw 302 passes through the pressure plate 401 and is threadedly connected to the pressure plate 401. Four first limiting rods 304 are fixedly connected at the four corners between the two first fixing plates 301. The four first limiting rods 304 pass through the pressure plate 401. Through the cooperation between the first support screw 302 and the pressure plate 401, the first control motor 303 drives the first support screw 302 to rotate. Under the action of the first support screw 302, the height of the pressure plate 401 can be precisely adjusted to achieve different degrees of compression.

[0019] A drive gear 402 is rotatably connected to the center of the pressure plate 401. Three driven gears 403 are rotatably connected to the outside of the drive gear 402 below the pressure plate 401. The drive gear 402 meshes with the three driven gears 403. An output motor 404 is fixedly mounted on the top of the pressure plate 401. The output end of the output motor 404 is connected to one end of the drive gear 402. Four stirring screws 405 are fixedly connected to the center of the drive gear 402 and the three driven gears 403. Through the engagement between the drive gear 402 and the driven gears 403, driven by the output motor 404, the drive gear 402 drives the three driven gears 403 to rotate, which in turn drives the four stirring screws 405 to rotate. The four stirring screws 405 can transport and stir the sludge.

[0020] A protective shell 406 is fixedly installed below the pressure plate 401. The protective shell 406 is sleeved on the outer wall of the driving gear 402 and the three driven gears 403, and the stirring screw 405 passes through the protective shell 406 to the outside. Because of the protective shell 406, the protective shell 406 can protect the driving gear 402 and the driven gears 403 and prevent silt from entering and affecting their normal operation.

[0021] The inner wall of the separation box 2 is provided with a second adjustment mechanism 5 below the first adjustment mechanism 3. The second adjustment mechanism 5 includes two second fixing plates 501, which are fixedly installed on the inner wall of one side of the separation box 2. A second support screw 502 is rotatably connected between the two second fixing plates 501 at the center position. A second control motor 503 is fixedly installed at the bottom of the separation box 2. The output end of the second control motor 503 is connected to one end of the second support screw 502. Four second limit rods 504 are fixedly installed at the four corners between the two second fixing plates 501. A filter press mechanism 6 is provided on one side of the second adjusting mechanism 5. The filter press mechanism 6 includes a first filter plate 601. A housing 602 is fixedly installed on one side of the first filter plate 601. A drive gear 603 is rotatably connected to the inner wall of the housing 602. Two output gears 604 are rotatably connected to the inner wall of the housing 602 on both sides of the drive gear 603. Both output gears 604 mesh with the drive gear 603. Two half gears 605 are fixedly connected to the ends of the two output gears 604, respectively. The two half gears 605 face the same direction. A reciprocating rod 606 is slidably connected between the inner walls of the housing 602. The reciprocating rod 606 passes through the top and bottom of the housing 602. The teeth of the two half gears 605 mesh with the ring teeth of the reciprocating rod 606. A reciprocating plate 608 is fixedly connected to the top of the reciprocating rod 606. The reciprocating plate 608 slides between the inner walls of the first filter plate 601. Because the first filter plate 601 has a filter press structure, the second support screw 502... Under the action of the motor, the first filter plate 601 moves upward. During the movement, the output end of the reciprocating motor 607 drives the drive gear 603 to rotate. The drive gear 603 drives the two half gears 605 to rotate synchronously through the two output gears 604. Since the teeth of the half gears 605 mesh with the ring teeth of the reciprocating rod 606, and the two half gears 605 face the same direction, the two half gears 605 drive the reciprocating rod 606 to move up and down repeatedly during rotation. During the movement, the reciprocating rod 606 drives the reciprocating plate 608 to move up and down between the inner walls of the first filter plate 601. During the pressure filtration process, the sludge near the first filter plate 601 can flow, preventing the sludge from condensing and affecting the filtration effect of the first filter plate 601. The size of the second support screw 502 is matched with the size of the separation box 2. The second support screw 502 passes through one side of the first filter plate 601 and is threaded to it. All four second limit rods 504 pass through the first filter plate 601. Four second limiting rods 504 restrict the first filter plate 601 to only move in a straight line up and down, ensuring the stability of the first filter plate 601 during the filtration process and helping to achieve more precise filtration of solid-liquid mixtures. Because the first filter plate 601 is provided, and the size of the first filter plate 601 matches the separation box 2, it can perform large-area filtration of solid-liquid mixtures. The threaded connection with the second support screw 502 and the through-hole of the second limiting rods 504 allow the position of the first filter plate 601 to be precisely adjusted as needed to adapt to the solid-liquid separation requirements of different sludge volumes, thereby improving filtration efficiency and quality.

[0022] Two sealing shells 7 are fixedly installed at the threaded connection points of the pressure plate 401 and the first filter plate 601 with the first support screw 302 and the second support screw 502, respectively. The sealing shells 7 are hollow. The first support screw 302 and the first limiting rod 304 pass through the sealing shells 7 connected to the pressure plate 401, and the second support screw 502 and the second limiting rod 504 pass through the sealing shells 7 connected to the first filter plate 601. During the up-and-down movement of the pressure plate 401 and the first filter plate 601, the leakage of solid-liquid mixture at the threaded connection points can be effectively prevented.

[0023] A filter box 8 is fixedly installed on one side of the separation box 2 above the base 1. A suction pump 9 is fixedly installed between the separation box 2 and the filter box 8 above the base 1. The input end of the suction pump 9 is connected to the bottom of the separation box 2, and the output end of the suction pump 9 is fixedly connected to a connecting pipe 10. The end of the connecting pipe 10 away from the suction pump 9 is connected to the top of the filter box 8. Through the cooperation between the suction pump 9 and the connecting pipe 10, the suction pump 9 can draw liquid from the bottom of the separation box 2 through the connecting pipe 10 into the filter box 8, realizing the transfer of liquid between two different processing stages, which is convenient to operate. The filter box 8 is used to further process the liquid drawn from the separation box 2. The liquid entering it is filtered a second time by the second filter plate 12. The liquid after the first solid-liquid separation may still contain some small impurities. The second filtration can further remove these impurities, thereby improving the purity of the liquid.

[0024] Two fixed brackets 11 are fixedly installed between the inner walls of the filter box 8. A second filter plate 12 is provided on one side of the filter box 8. The second filter plate 12 passes through one side of the filter box 8 and is located between the two fixed brackets 11. It can be pulled out and slid through a sliding groove and slider structure. The second filter plate 12 can be easily cleaned and replaced by pulling it out, which improves the flexibility and filtration efficiency of the filter box 8.

[0025] A guide plate 13 is fixedly installed at the bottom of the filter box 8. The guide plate 13 is designed with an inclination. A drain port 14 is opened near the bottom of the filter box 8. The inclination direction of the guide plate 13 is towards the drain port 14. Because of the guide plate 13, the inclination design of the guide plate 13 can guide the liquid after secondary filtration to flow smoothly to the drain port 14, preventing the liquid from accumulating at the bottom of the filter box 8. At the same time, the drain port 14, in conjunction with the guide plate 13, can ensure that the liquid after secondary filtration can be discharged from the filter box 8 in a timely and smooth manner, avoiding problems such as liquid backflow and ensuring the normal operation of the filter box 8.

[0026] The working principle of this invention is as follows: When using the device, sewage sludge requiring solid-liquid separation is injected into the separation tank 2 through the injection port 18. After entering the separation tank 2, the sewage sludge is positioned above the first filter plate 601. The first support screw 302 of the first adjusting mechanism 3 rotates under the drive of the first control motor 303, causing the pressure plate 401 to press down. The first filter plate 601 moves upward under the cooperation of the second support screw 502 of the second adjusting mechanism 5 and the second control motor 503. The pressure plate 401 and the first filter plate 601 cooperate to squeeze and perform solid-liquid separation on the sewage sludge. The output end of the reciprocating motor 607 drives the drive gear 603 to rotate. The drive gear 603 drives the two half gears 605 to rotate through the two output gears 604. Under the action of the two half gears 605, the reciprocating rod 606 moves up and down repeatedly on the inner wall of the housing 602, causing the reciprocating plate 608 to move up and down repeatedly on the inner wall of the first filter plate 601, preventing the sludge adhering to the first filter plate 601 from condensing. The output motor 404 drives the drive gear 402 to rotate. The rotation of the drive gear 402 drives the three driven gears 403 meshing with it to rotate, which in turn drives the four stirring screws 405 to rotate. The stirring screws 405 are between the pressure plate 401 and the first filter plate 601, and convey the sewage sludge near the pressure plate 401 to the first filter plate 601, so that the sewage sludge between the pressure plate 401 and the first filter plate 601 is fully and evenly squeezed to achieve solid-liquid separation. The liquid after solid-liquid separation falls to the bottom of the separation box 2 under the action of gravity after passing through the first filter plate 601. The suction pump 9 draws the liquid and delivers it to the filter box 8 through the connecting pipe 10. In the filter box 8, the liquid first undergoes secondary filtration through the second filter plate 12. The liquid after secondary filtration falls to the bottom of the filter box 8 and is discharged through the drain port 14. After the solid-liquid separation process is completed, the telescopic rod 16 retracts and drives the sealing plate 15 to rotate and open through the connecting block 17, thereby cleaning the impurities in the separation box 2. Then, the second filter plate 12 is removed by pulling, and the impurities filtered out by the second filter plate 12 are cleaned before using the equipment.
