Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater treatment device for pig farming with multi-layer filtration effect. Background Technology

[0002] In order to prevent pigs from getting sick, pigsties need to be cleaned regularly. However, the untreated wastewater from pig farming contains organic pollutants, nitrogen and phosphorus compounds and antibiotic residues. At the same time, the organic matter in the wastewater will produce foul-smelling gases when decomposed anaerobically, which will affect the lives of surrounding residents. This means that direct discharge of pig farming wastewater will lead to problems such as eutrophication of water bodies, soil compaction and air pollution. Therefore, it is necessary to use pig farming wastewater treatment equipment.

[0003] Existing publication number CN218146109U discloses a pig farm wastewater treatment device, including a treatment box, a filter frame, a cleaning component, a residue collection box, and an adsorption box. An inlet pipe is fixedly embedded in the top of the treatment box. The filter frame is fixedly installed inside the treatment box, and a filter plate is fixedly installed inside the filter frame. The cleaning component is located inside the treatment box and above the filter frame. A drain outlet is opened on the right side wall of the treatment box, and a drain pipe is fixedly embedded in the drain outlet. The residue collection box is located directly below the free end of the drain pipe. A drain pipe is fixedly embedded in the bottom left side of the treatment box. The adsorption box is embedded in the corresponding drain pipe, and an activated carbon adsorption filter element is installed inside the adsorption box. This device has a high wastewater treatment effect while avoiding filter plate clogging. Furthermore, the residue on the filter plate does not require manual cleaning, effectively preventing personnel from directly viewing wastewater and fecal residue, thus avoiding nausea and vomiting. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] After the wastewater filtered by the filter plate is disinfected, there will be some suspended solids and colloidal substances. If it is discharged directly and filtered only by the activated carbon adsorption filter, the suspended solids or colloidal substances may clog the activated carbon adsorption filter, affecting the adsorption of the activated carbon adsorption filter and the discharge of the treated wastewater.

[0005] Therefore, a pig farm wastewater treatment device with multi-layer filtration effect is proposed to address the above problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] Example 1

[0022] As attached Figures 1 to 4The illustrated pig wastewater treatment device with multi-layer filtration includes a treatment box 1. A filter frame 4 is installed on one side of the bottom of the treatment box 1. A connecting frame 2 is installed inside the treatment box 1 and above the filter frame 4. A filter screen 3 is fixedly installed on the connecting frame 2. Two handles 15 for pulling the filter frame 4 are symmetrically fixedly installed at the top of the filter frame 4. Two handles 15 for pulling the connecting frame 2 and the filter screen 3 are symmetrically installed on the surface of the connecting frame 2. Two connecting posts 5 are symmetrically installed at the top of the filter frame 4. Two connecting posts 5 are symmetrically installed on both sides of the connecting frame 2. A fixing plate 6 is fixedly installed on the inner side wall of the treatment box 1 and above each connecting post 5. Two limiting seats 7 are symmetrically installed on the fixing plate 6. A clamping block 8 for clamping the connecting post 5 is rotatably connected between the two limiting seats 7. A fixing block 9 is fixedly installed on the outer side wall of each of the two clamping blocks 8. A compression spring 10 is connected between the two fixing blocks 9 and the fixing plate 6.

[0023] Specifically, during use, the filter frame 4 can filter and collect suspended or colloidal substances generated after adding disinfectant, preventing these substances from clogging the activated carbon adsorption filter element in the adsorption box 23. Simultaneously, pressing the connecting frame 2 and the filter frame 4 causes the connecting post 5 fixed on them to move downwards. The arc-shaped outer wall of the moving connecting post 5 then presses against the two clamping blocks 8, opening them until the connecting post 5 moves between the two clamping blocks 8. The compression spring 10 then pushes the fixing block 9, which in turn causes the clamping blocks 8 to clamp and fix the connecting post 5 on the filter frame 4 and the filter screen 3. This structure allows for quick and convenient disassembly, cleaning, or installation of the filter screen 3 and the filter frame 4, improving the device's practicality.

[0024] Example 2

[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, a mounting base 11 is fixedly installed on one side of the treatment box 1, and a threaded rod 12 is rotatably connected inside the mounting base 11. A slider 13 is then threadedly connected to the outside of the threaded rod 12, and a toggle plate 14 is fixedly installed on the surface of the slider 13. Simultaneously, a guide plate 16 is fixedly installed inside the treatment box 1, located on one side of the filter screen 3. A drain pipe 17, connected to the bottom end of the guide plate 16, is then connected to the side wall of the treatment box 1. One end of the drain pipe 17 is connected to a residue collection box 18. The surface of the guide plate 16 is... Equipped with an ultraviolet germicidal lamp 19, the threaded rod 12 is driven by a servo motor connected to one end. The rotating threaded rod 12 then drives the slider 13 and the actuating plate 14 to move. The actuating plate 14 moves the impurities accumulated on the surface of the filter screen 3, and after being moved to the guide plate 16, they slide down the drain pipe 17 and fall into the residue collection box 18 for unified collection. The ultraviolet germicidal lamp 19 can also be used to further disinfect and sterilize the wastewater.

[0027] In a preferred embodiment, a stirring shaft 20 is rotatably connected inside the treatment tank 1 and below the filter screen 3. Multiple stirring rods 21 are fixedly arranged at equal intervals on the outside of the stirring shaft 20. A drive motor is connected to one end of the stirring shaft 20. A feeding port for adding chemicals into the treatment tank 1 is provided on the rear side wall of the treatment tank 1. Finally, the drive motor is fixed to the outer side wall of the treatment tank 1 with screws. In use, the drive motor at one end of the stirring shaft 20 can drive the stirring shaft 20 and the stirring rods 21 to rotate. Then, the rotating stirring rods 21 stir the sewage and the added disinfectant in the treatment tank 1.

[0028] In a preferred embodiment, a drain pipe 22 is connected to the side wall of the treatment tank 1 and located on the side of the filter frame 4. An adsorption tank 23 is then connected to the drain pipe 22. Finally, an activated carbon adsorption filter element is installed in the adsorption tank 23. After the sewage in the treatment tank 1 is filtered, disinfected, and sterilized, it is discharged through the drain pipe 22. At this time, the treated water will pass through the adsorption tank 23 and the activated carbon adsorption filter element installed in the adsorption tank 23 will adsorb the odor in the water.

[0029] In this embodiment, the servo motor, drive motor, and ultraviolet germicidal lamp 19 are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not go into detail here.

[0030] The working process of this utility model is as follows: First, the filter frame 4 can filter and collect suspended or colloidal substances generated after adding disinfectant, thus preventing the suspended or colloidal substances from clogging the activated carbon adsorption filter element in the adsorption box 23. At the same time, pressing the connecting frame 2 and the filter frame 4 causes the connecting post 5 fixed on the connecting frame 2 and the filter frame 4 to move down. Then, the arc-shaped outer wall of the moving connecting post 5 squeezes the two clamping blocks 8 to open until the connecting post 5 moves between the two clamping blocks 8. Then, the compression spring 10 pushes the fixing block 9, and then the pushed fixing block 9 drives the clamping block 8 to clamp and fix the connecting post 5 on the filter frame 4 and the filter screen 3. This structure can quickly and conveniently complete the disassembly, cleaning or fixing installation of the filter screen 3 and the filter frame 4, improving the practicality of the device.

[0031] When treating wastewater from pig farming, the wastewater is first fed into the treatment tank 1 through the feeding port at the top of the treatment tank 1. Then, the solid impurities in the wastewater are filtered through the filter screen 3. The sliding block 13 and the agitator 14 are then moved by the rotating threaded rod 12. The moving agitator 14 moves the impurities accumulated on the surface of the filter screen 3. After being moved to the guide plate 16, the impurities slide down the drain pipe 17 and fall into the residue collection box 18 for unified collection. At the same time, the driving motor at one end of the stirring shaft 20 drives the stirring shaft 20 and the stirring rod 21 to rotate. The rotating stirring rod 21 then stirs the wastewater and the added disinfectant in the treatment tank 1. While the wastewater is being stirred, the wastewater can also be further disinfected and sterilized by the ultraviolet germicidal lamp 19. After being filtered by the filter frame 4, the wastewater can be discharged through the drain pipe 22. The activated carbon adsorption filter element in the adsorption box 23 adsorbs the odor in the water. The above is the working principle of this pig farming wastewater treatment device with multi-layer filtration effect.
