Description

Technical Field

[0001] This utility model relates to the field of livestock breeding technology, specifically a wastewater treatment device for pig farming. Background Technology

[0002] During the pig farming process, the daily cleaning and maintenance of the farm requires the use of a large amount of clean water for rinsing and cleaning to remove feces, urine and food residue, thereby preventing the growth of microorganisms that may affect the environment. In this process, some wastewater containing organic matter is inevitably generated.

[0003] Traditional solutions involve separating wastewater and manure residue, directly composting the manure residue, and then discharging or recycling the wastewater after microbial degradation. During the separation of wastewater and manure residue, mesh filters are typically used. However, if the mesh is embedded in the wastewater tank, the separated manure residue is difficult to remove, requiring manual shoveling or mechanical removal. If the mesh is angled in the wastewater tank, wastewater inevitably overflows during separation, causing environmental pollution. Therefore, a wastewater treatment device for pig farming is specifically provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pig farming wastewater treatment device, which solves the problem that when separating manure and sludge, mesh filtration is usually used. If the mesh is embedded in the wastewater tank, it is difficult to discharge the separated manure and sludge, requiring workers to shovel it or mechanical equipment to remove it. If the mesh is set at an angle in the wastewater tank, manure and sludge will inevitably flow out during separation, causing on-site environmental pollution.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a pig farming wastewater treatment device, including a manure biological purification tank, wherein an aeration component is provided in the manure biological purification tank, thereby increasing the dissolved oxygen content in the manure biological purification tank and accelerating the reproduction of aerobic bacteria.

[0006] A filter assembly is installed inside one end of the sewage biological purification box. The filter assembly includes a feed hopper and a filter screen that are hinged to each other. The outer side of the feed hopper is rotatably mounted on the side wall of the sewage biological purification box, and the inner side of the filter screen slides up and down along the side wall of the sewage biological purification box.

[0007] When the inner side of the filter screen slides to the lowest point, the hopper and the filter screen are arranged in a "V" shape in the sewage biological purification tank to filter and intercept impurities in the wastewater.

[0008] When the inner side of the filter screen slides to its highest point, the hopper and the surface of the filter screen are flush and the whole is tilted to discharge the intercepted impurities.

[0009] Preferably, the biological sewage purification tank has a discharge port on one side and a cleaning inlet installed on the top of the other side.

[0010] Preferably, the outer end of the hopper is hinged to the discharge port. A mesh plate is fixedly provided on the inner side of the hopper, and the mesh plate is hinged to the filter screen.

[0011] Preferably, the sewage biological purification box has sliding chambers on both sides of the middle section, and slide rails are fixedly installed in the sliding chambers, with the inner side of the filter screen sliding along the slide rails.

[0012] Preferably, both ends of the filter screen are rotatably connected to sliding blocks, and the sliding blocks are slidably connected to the outer surface of the slide rail.

[0013] Preferably, a winding machine is fixedly installed on the sewage biological purification box, and a traction steel cable is fixedly installed on the inner side of the filter screen. The winding machine is used to wind up and unwind the traction steel cable.

[0014] Preferably, a support shaft is fixedly installed at the upper middle part of the sewage biological purification tank, and a fixed pulley is installed on the support shaft, with the traction steel cable passing around the outer surface of the fixed pulley.

[0015] Preferably, the aeration assembly includes a blower fixed to the top of the sewage biological purification tank and multiple aeration discs installed at the bottom of the sewage biological purification tank, with an air guide pipe installed between the blower and the multiple aeration discs.

[0016] This utility model discloses a wastewater treatment device for pig farming, which has the following beneficial effects: The feeding hopper and the filter screen are arranged in a V-shape inside the manure biological purification tank. Manure and manure residue are pumped into the feeding hopper, and the manure and manure residue are separated by the mesh plate and the filter screen. The manure residue is retained on the V-shaped structure. When the moisture content of the manure residue drops to the point where there is no obvious dripping, the winding machine is started to wind up the traction steel cable, pulling the inner end of the filter screen upward. Finally, the top surface of the feeding hopper and the filter screen are roughly horizontal, while the side near the feeding port is tilted downward. At this time, the manure residue slides out naturally through the feeding port under the action of gravity, thereby facilitating the separation of manure residue and reducing pollution of the working environment.

[0023] This application provides a pig farming wastewater treatment device, which solves the problem that when separating manure and sludge, a mesh filter is usually used. If the mesh is embedded in the wastewater tank, it is difficult to discharge the separated manure and sludge, requiring workers to shovel it or to remove it with mechanical equipment. If the mesh is set at an angle in the wastewater tank, manure and water will inevitably flow out during separation, causing on-site environmental pollution.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] This utility model discloses a wastewater treatment device for pig farming.

[0026] Example 1

[0027] According to the appendix Figure 1-3 As shown, it includes a sewage biological purification tank 1, which is equipped with an aeration component 3. The aeration component 3 increases the dissolved oxygen content of the sewage biological purification tank 1 and accelerates the reproduction of aerobic bacteria.

[0028] A filter assembly 2 is installed inside one end of the sewage biological purification tank 1. The filter assembly 2 includes a feed hopper 21 and a filter screen 22 that are hinged to each other. The outer side of the feed hopper 21 is rotatably mounted on the side wall of the sewage biological purification tank 1. The inner side of the filter screen 22 slides up and down along the side wall of the sewage biological purification tank 1. When the inner side of the filter screen 22 slides to the lowest point, the feed hopper 21 and the filter screen 22 are arranged in a "V" shape in the sewage biological purification tank 1 to filter and intercept impurities in the wastewater.

[0029] The sewage biological purification tank 1 has a discharge port 12 on one side and a cleaning inlet 14 installed on the top of the other side. After the sewage biological purification tank 1 is used, maintenance personnel can enter through the cleaning inlet 14 to clean the inner wall. At the same time, a submersible pump can be put into the interior through the cleaning inlet 14 to pump out the sludge deposited at the bottom.

[0030] The outer end of the hopper 21 is hinged to the discharge port 12. A mesh plate 29 is fixedly installed on the inner side of the hopper 21, and the mesh plate 29 is hinged to the filter screen plate 22 to form a V-shaped filtration space for the interception and drainage of fecal residue.

[0031] The aeration assembly 3 includes a blower 31 fixed to the top of the sewage biological purification tank 1 and multiple aeration discs 32 installed at the bottom of the sewage biological purification tank 1. An air guide pipe 33 is installed between the blower 31 and the multiple aeration discs 32.

[0032] Working principle: When in use, the hopper 21 and the filter screen 22 are arranged in a V-shape inside the sewage biological purification tank 1. At this time, sewage and sludge are pumped into the hopper 21 through the discharge port 12 by a mud pump. The mesh plate 29 and the filter screen 22 are used to separate the sewage and sludge, so that the sludge is retained on the V-shaped structure. The sewage enters the sewage biological purification tank 1. By adding aerobic bacteria and lactic acid bacteria and other microbial strains, and at the same time starting the blower 31, air enters the aeration plate 32 through the air pipe 33 to aerate the sewage, accelerate the reproduction of microorganisms, and after the microorganisms decompose the organic matter in the sewage, the supernatant is discharged into the secondary sedimentation tank for sedimentation, and finally the wastewater is purified.

[0033] Example 2

[0034] According to the appendix Figure 1-3 As shown, based on Embodiment 1, more specifically, when the inner side of the filter screen 22 slides to the highest point, the surface of the hopper 21 and the filter screen 22 are flush and the whole is inclined, which is used to discharge the intercepted impurities.

[0035] The sewage biological purification box 1 has sliding chambers 13 on both sides of the middle. Slide rails 26 are fixedly installed in the sliding chambers 13. The inner side of the filter screen plate 22 slides along the slide rails 26. Sliding blocks 27 are rotatably connected to both ends of the filter screen plate 22. The sliding blocks 27 are slidably connected to the outer surface of the slide rails 26. During the up and down sliding of the inner end of the filter screen plate 22, the sliding blocks 27 rotate at both ends of the filter screen plate 22, which allows the filter screen plate 22 to move along the slide rails 26 and prevents it from tilting.

[0036] A winding machine 28 is fixedly installed on the sewage biological purification box 1. A traction steel cable 23 is fixedly installed on the inner side of the filter screen 22. The winding machine 28 is used to wind up and unwind the traction steel cable 23. A support shaft 24 is fixedly installed at the upper middle part of the sewage biological purification box 1. A fixed pulley 25 is installed on the support shaft 24. The traction steel cable 23 passes around the outer surface of the fixed pulley 25, thereby changing the direction of the tension of the traction steel cable 23, which makes it easier to lift the inner end of the filter screen 22 upward.

[0037] Working principle: During the manure-water separation stage, the manure residue remains on the V-shaped structure and is drained using the mesh plate 29 and filter screen 22. When the moisture content of the manure residue decreases to the point where there is no obvious dripping, the winding machine 28 is started to wind up the traction cable 23. At this time, the other end of the traction cable 23 pulls the inner end of the filter screen 22 upward. The hinge point between the filter screen 22 and the hopper 21 gradually rises, and the outer end of the hopper 21 rotates in the discharge port 12. Finally, the top surface of the hopper 21 and the filter screen 22 are roughly horizontal, while the side near the discharge port 12 tilts downward. At this time, the manure residue slides out naturally through the discharge port 12 under the action of gravity, which facilitates the separation of manure residue and reduces pollution in the working environment.

[0038] 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 illustrative of the principles of this 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 claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
