A solid-liquid separation device for rural wastewater treatment

Abstract

This utility model discloses a solid-liquid separation device for rural wastewater treatment, belonging to the field of wastewater treatment technology. It includes a base with an inclined plate mounted on it, a working box mounted on the base, and a first separation plate and a second separation plate installed inside the working box. A baffle is slidably mounted on the second separation plate, and a rack is connected to the baffle. This solid-liquid separation device for rural wastewater treatment utilizes a rotating shaft and gears mounted on it. Due to the meshing of the gears and rack, the rotation of the gears drives the rack and baffle to move. When the baffle moves from the second separation plate to a suitable position, the operator activates a motor installed inside the waterproof box. The output shaft of the motor drives a rotating rod to rotate, which in turn drives a scraper to rotate. The scraper scrapes away smaller solid impurities remaining on the second separation plate into a collection box, eliminating the need for manual collection of solid impurities and reducing workload.

Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a solid-liquid separation device for rural wastewater treatment. Background Technology

[0002] Wastewater treatment involves using physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, making full use of water resources. When using physical methods to treat wastewater, it is necessary to filter the wastewater to separate the wastewater from impurities into solid and liquid components.

[0003] Currently, solid-liquid separation devices for wastewater treatment use filter screens for solid-liquid separation. However, solid impurities in the wastewater can remain on the filter screens, causing them to become clogged. This requires manual cleaning of the solid impurities, which is very inconvenient and increases the workload of the staff. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a solid-liquid separation device for rural wastewater treatment, which solves the problem that existing solid-liquid separation devices for wastewater treatment use filter screens for solid-liquid separation, but solid impurities in the wastewater will remain on the filter screens, causing filter screen blockage. This requires manual cleaning of solid impurities, which is very inconvenient and increases the workload of the staff.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solid-liquid separation device for rural wastewater treatment, comprising a base, an inclined plate mounted on the base, a working box mounted on the base, a first separation plate and a second separation plate mounted inside the working box, a baffle slidably mounted on the second separation plate, a rack connected to the baffle, a support plate mounted on the outer wall of the working box, a second motor mounted on the support plate, a rotating shaft connected to the output shaft of the second motor, a gear connected to the end of the rotating shaft, the gear meshing with the rack, a waterproof box mounted at the bottom of the second separation plate, and a first motor mounted inside the waterproof box.

[0006] As a further embodiment of this utility model: a push plate is slidably mounted on the first separation plate, and a push-pull rod is mounted on the push plate.

[0007] As a further embodiment of this utility model: the working box is provided with a liquid injection port, and the working box is equipped with a sealing door.

[0008] As a further embodiment of this utility model: a handle is installed on the sealing door, and a drain pipe is installed on the work box.

[0009] As a further embodiment of this utility model: a collection box is slidably mounted on the work box, and a handle is mounted on the collection box.

[0010] As a further embodiment of this utility model: a rotating rod is connected to the output shaft of the motor, and a scraper is installed at the end of the rotating rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This solid-liquid separation device for rural wastewater treatment is equipped with a motor, gears, racks, and a rotating shaft. During operation, the operator turns on the motor installed on the support plate. The operation of the motor drives the rotating shaft and the gear installed on the shaft to rotate. Because the gear and rack mesh, the rotation of the gear drives the rack and baffle to move. When the baffle moves from the second separation plate to the appropriate position, the operator turns on the motor installed in the waterproof tank. The output shaft of the motor drives the rotating rod to rotate. The rotation of the rotating rod drives the scraper to rotate. The scraper rotates, thereby scraping the smaller solid impurities remaining on the second separation plate into the collection tank. There is no need for the operator to manually collect solid impurities, which reduces the workload. 2. This solid-liquid separation device for rural wastewater treatment consists of a first separation plate, a sealing door, a push-pull rod, and a push plate. During operation, workers pour wastewater into the working tank from the injection port. The wastewater passes through the first and second separation plates. When the wastewater passes through the first separation plate, larger solid impurities remain on it. When the first separation plate needs to be cleaned, workers open the sealing door and push the push-pull rod. The push-pull rod moves the push plate connected to its end, which moves on the first separation plate, thus pushing the larger solid impurities out of the working tank. This prevents the first separation plate from being blocked by solid impurities and ensures the normal operation of subsequent work. Attached Figure Description

Detailed Implementation

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-4 As shown, this utility model provides a technical solution: a solid-liquid separation device for rural wastewater treatment, including a base 1, an inclined plate 12 installed on the base 1, a working box 2 installed on the base 1, a collection box 18 slidably installed on the working box 2, and a handle 9 installed on the collection box 18.

[0015] The working box 2 is equipped with a first separation plate 11 and a second separation plate 13. A push plate 23 is slidably installed on the first separation plate 11, and a push-pull rod 6 is installed on the push plate 23. The working box 2 is provided with an injection port 3 and a sealing door 4. Because of the push-pull rod 6, the staff can move the push plate 23 by pushing the push-pull rod 6, thereby cleaning out the larger solid impurities remaining on the first separation plate 11 from the working box 2 and preventing the first separation plate 11 from being blocked.

[0016] A handle 5 is installed on the sealed door 4, and a drain pipe 8 is installed on the working box 2. Because of the drain pipe 8, the separated waste liquid can be discharged into the working box 2, which facilitates subsequent collection and improves work efficiency.

[0017] A baffle 19 is slidably installed on the second separation plate 13, and a rack 20 is connected to the baffle 19. A support plate 7 is installed on the outer wall of the working box 2, and a motor 21 is installed on the support plate 7. Because of the installation of the motor 21, the baffle 19 can be moved by the motor 21, which facilitates the subsequent collection of smaller impurities on the second separation plate 13 and ensures the normal operation of the work.

[0018] A rotating shaft 22 is connected to the output shaft of motor 21. A gear 10 is connected to the end of the rotating shaft 22. The gear 10 meshes with the rack 20. A waterproof box 14 is installed at the bottom of the second separating plate 13. Motor 15 is installed inside the waterproof box 14. A rotating rod 16 is connected to the output shaft of motor 15. A scraper 17 is installed at the end of the rotating rod 16. Because motor 15 is installed, it can drive the scraper 17 to scrape smaller solid impurities on the first separating plate 11 into the collection box 18. There is no need for manual cleaning and collection by the staff, which reduces the workload of the staff.

[0019] The working principle of this utility model is as follows: When working, the operator opens the motor 21 installed on the support plate 7. The motor 21 drives the rotating shaft 22 and the gear 10 installed on the rotating shaft 22 to rotate. Since the gear 10 and the rack 20 mesh, the rotation of the gear 10 drives the rack 20 and the baffle 19 to move. When the baffle 19 moves from the second separation plate 13 to the appropriate position, the operator opens the motor 15 installed in the waterproof box 14. The output shaft of the motor 15 drives the rotating rod 16 to rotate. The rotation of the rotating rod 16 drives the scraper 17 to rotate. The scraper 17 rotates, thereby scraping the smaller solid impurities remaining on the second separation plate 13 into the collection box 18. During operation, the worker pours wastewater into the working box 2 from the injection port 3. The wastewater passes through the first separation plate 11 and the second separation plate 13. When the wastewater passes through the first separation plate 11, larger solid impurities remain on the first separation plate 11. When the first separation plate 11 needs to be cleaned, the worker opens the sealing door 4 and then pushes the push rod 6. The push rod 6 drives the push plate 23 connected to its end to move. The push plate 23 moves on the first separation plate 11, thereby pushing the larger solid impurities out of the working box 2.
