Description

Technical Field

[0001] This utility model relates to the field of water pollution control technology, specifically a solid-liquid separation device for water pollution control. Background Technology

[0002] Water pollution is one of the most significant environmental problems facing the world today, posing a serious threat to ecosystems and human health. One source of water pollution is the large amounts of wastewater generated from industrial and agricultural activities, which contain organic matter, heavy metals, and other harmful substances. Solid-liquid separation technology, as an effective method for water pollution control, can significantly reduce the concentration of pollutants in wastewater by separating solid particles from the liquid.

[0003] Chinese Patent CN220899645U discloses a solid-liquid separation device for water pollution control. It includes a housing with a first filter plate and a second filter plate installed on it, the second filter plate being directly below the first filter plate. A motor's output shaft drives a threaded rod to rotate, which in turn drives a cleaning brush via a first fixed block to clean solid debris from the first filter plate. A cylinder, via a second fixed block, drives a sliding plate upwards, sweeping solid impurities into a waste collection box, thus cleaning the first filter plate.

[0004] Regarding the aforementioned technologies, this device has some shortcomings. In actual use, the cleaning method for the two filter plates is as follows: the first filter plate is automatically cleaned, while the second filter plate requires manual disassembly for cleaning or replacement. This asymmetrical cleaning method leads to reduced efficiency during operation, as users need additional time and labor to clean the second filter plate. This not only increases operational complexity but may also prolong equipment downtime, affecting overall processing capacity and operational efficiency. Therefore, it is necessary to provide a solid-liquid separation device for water pollution control to solve the above-mentioned technical problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 One embodiment provided by this utility model:

[0029] A solid-liquid separation device for water pollution control, comprising:

[0030] Separation box 1, support frame 2 is fixedly installed at the bottom of separation box 1, fixed frame 7 is fixedly installed on the upper side of one side of separation box 1, threaded rod 8 is rotatably installed between one side of separation box 1 and fixed frame 7, first motor 10 is fixedly installed on one side of fixed frame 7, and the drive end of the first motor 10 passes through one side of fixed frame 7 and extends to the other side of fixed frame 7 and is fixedly connected to one end of threaded rod 8. Limiting rods 9 are fixedly installed on one side of separation box 1 above and below threaded rod 8 and between fixed frame 7.

[0031] A mounting plate 12 is fitted on the outer wall of the threaded rod 8. A filter assembly 4 is symmetrically distributed on one side of the mounting plate 12. An installation port 21 corresponding to the position and number of the filter assembly 4 is opened on the upper side of one side of the separation box 1. The installation port 21 is slidably inserted into the filter assembly 4. A limiting groove 11 corresponding to the position and number of the filter assembly 4 is opened on the upper side of the interior of the separation box 1. The limiting groove 11 is slidably connected to the filter assembly 4.

[0032] A waste discharge port 15 is provided on the lower side of one side of the separation box 1, and a drain pipe 3 is fixedly installed on the lower side of the other side of the separation box 1. A push plate 6 is fixedly installed on one side of the inner wall of the separation box 1 above the two installation ports 21, and a hard brush 5 is fixedly installed at the bottom of the push plate 6.

[0033] A sealing guide plate 20 is rotatably installed at the bottom of the separation box 1, and the sealing guide plate 20 slides in contact with the inner wall of the separation box 1. Arc grooves 19 are opened on both sides of the lower part of the inner wall of the separation box 1, and the arc grooves 19 slide in contact with the sealing guide plate 20. The bottom of the separation box 1 has symmetrically distributed positioning sliding holes 18. An arc plate 13 is fixedly installed at the bottom of the sealing guide plate 20, and the arc plate 13 slides in connection with the positioning sliding holes 18. A rack 14 is fixedly embedded on the outer surface of the arc plate 13. A second motor 16 is fixedly installed on the support frame 2. A gear 17 is fixedly installed at the drive end of the second motor 16, and the gear 17 meshes with the rack 14. A sealing strip is glued to the side of the sealing guide plate 20. The sealing strip on the side of the sealing guide plate 20 ensures the sealing effect between the sealing guide plate 20 and the inner wall of the separation box 1 and the arc grooves 19, and can stably guide both solid impurities and liquids, avoiding leakage.

[0034] In one embodiment, a threaded hole adapted to the threaded rod 8 is provided on one side of the mounting plate 12, and the mounting plate 12 is threadedly connected to the threaded rod 8 through the threaded hole on one side.

[0035] In one preferred embodiment, sliding holes adapted to the limiting rod 9 are provided on both the upper and lower sides of one side of the mounting plate 12, and the mounting plate 12 is slidably connected to the limiting rod 9 through the sliding holes on the upper and lower sides of one side, thereby realizing stable lateral movement of the mounting plate 12.

[0036] In one embodiment, a sealing gasket is adhered to one side of the mounting plate 12 near the separation tank 1, and a transparent visual glass 22 is fixedly installed on the lower front of the separation tank 1 to prevent sewage from leaking through the mounting port 21 during the sewage treatment process. The transparent visual glass 22 allows staff to observe the discharge and solid waste from outside the separation tank 1, so as to intervene in time and ensure the stable operation of the device.

[0037] In one preferred embodiment, the filter assembly 4 consists of a U-shaped frame and a stainless steel filter screen, with the stainless steel filter screen fixedly installed inside the U-shaped frame. The mesh size of the stainless steel filter screens on the two filter assemblies 4 decreases from top to bottom. The filter assembly 4 is fixedly connected to the mounting plate 12 through the U-shaped frame, and the filter assembly 4 is slidably connected to the sealing guide plate 20 and the limiting groove 11 through the U-shaped frame. The filter assembly 4 uses a stainless steel filter screen as the filter structure, and with the brushing action of the hard brush 5, it can effectively clean the impurities clogging the mesh of the stainless steel filter screen, which is more convenient and simpler to clean than a regular filter screen.

[0038] The working principle of this utility model is as follows: The entire device is controlled by a main control button. Since the device matched with the control button is a common device and belongs to existing common knowledge technology, its electrical connection relationship and specific circuit structure will not be described in detail here. During use, sewage is flushed in through the top opening of the separation box 1 and will be filtered sequentially by two filter components 4. The filtered impurities will be trapped on the two filter components 4. When cleaning later, the sewage discharge is stopped, and the first motor 10 is started to work. The drive end of the first motor 10 drives the threaded rod 8 to rotate. Through the threaded transmission between the threaded rod 8 and the mounting plate 12, and the sliding relationship between the mounting plate 12 and the limit rod 9, the mounting plate 12 moves laterally stably. The movement of the mounting plate 12 drives the two filter components 4 from the mounting port 2. The filter assembly 4 moves to the right side of the separation tank 1. During this movement, the hard brush 5 located at the bottom of the push plate 6 directly brushes off the impurities filtered through the stainless steel filter screen and traps them on the left side of the hard brush 5 and push plate 6. As the filter assembly 4 continues to move, it moves away from the bottom of the hard brush 5. At this time, the impurities cleaned by the hard brush 5 and push plate 6 fall directly to the bottom of the separation tank 1 under gravity, completing the simultaneous cleaning of impurities on both filter assemblies 4. Subsequently, driven by the first motor 10, the two filter assemblies 4 are reset to the interior of the separation tank 1 to continue solid-liquid separation. This device, through mechanical drive, can automatically clean both filter assemblies 4 simultaneously without manual operation by the user, further simplifying the maintenance process. The selection of stainless steel filter screen ensures its corrosion resistance and wear resistance, enabling long-term stable filtration of sewage. At the same time, the brushing action of the hard brush 5 directly cleans the impurities on the stainless steel filter screen, ensuring high-efficiency filtration performance. This not only improves the ease of cleaning, but also ensures the stability and reliability of the device during long-term operation, providing users with a more convenient and efficient user experience.

[0039] After the wastewater filtered by the filter assembly 4 falls into the lower part of the separation tank 1, it flows out from the drain pipe 3 through the guide plate 20. When cleaning the impurities on the filter assembly 4, the second motor 16 is first controlled to start working. The drive end of the second motor 16 drives the gear 17 to rotate. Through the meshing of the gear 17 and the rack 14, the rack 14 and the arc plate 13 drive the seal guide plate 20 to flip, so that the seal guide plate 20 flips to the right and changes its tilt direction. In this way, the cleaned impurities will fall on the top of the seal guide plate 20 and slide out through the waste outlet 15 through the guide plate 20. By changing the position of the seal guide plate 20, the wastewater and impurities can be discharged separately, which is convenient for the staff to collect and treat the wastewater and impurities separately.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
