Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a pig manure water separator and a pig manure wastewater treatment device. Background Technology

[0002] Pig manure refers to the excrement produced by pig farming. It has a fine texture, is rich in organic matter and nitrogen, phosphorus, and potassium nutrients, and decomposes slowly. It is mostly used as base fertilizer in farmland. However, its high water content makes it prone to clumping, and direct application is difficult to meet the needs of field application. To improve fertilizer efficiency and ease of application, it is necessary to separate the water before using it as base fertilizer, so as to achieve efficient recycling of planting and breeding resources.

[0003] The prior art, such as the pig manure water separator and pig manure sewage treatment device disclosed in announcement number CN220149438U, includes a frame, a manure-water separation mechanism installed on the top of the frame, the manure-water separation mechanism including a separation box, a retainer installed on one side of the surface of the separation box, a drive motor installed on the other side of the surface of the separation box, and a control box installed on one side of the drive motor. The output end of the drive motor is connected to a transmission shaft through a coupling, and a spiral blade is fitted on the transmission shaft. A filter tank, a sedimentation tank and a discharge tank are respectively provided on one side of the frame, and the filter tank, sedimentation tank and discharge tank are all connected by a drain pipe.

[0004] However, this technical solution has the following problems in practical use: A drum-shaped filter screen is installed inside the separation chamber, with the screen and drive shaft aligned on the same axis. The rotating drum separates water and urine from the pig manure, which are then guided through a curved pipe into the filtration tank, completing the initial separation of the solid and liquid phases. However, because the mesh size of the drum-shaped filter screen is fixed and it is located inside the separation chamber, small solid impurities are easily trapped in the mesh after being squeezed by the extrusion plate. This blockage cannot be cleared, preventing the normal passage of urine and hindering continuous separation. Consequently, the separation process is interrupted, ultimately limiting the improvement of the solid-liquid separation effect of the pig manure. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art where the mesh size of the roller-shaped filter screen is fixed and the filter screen is set inside the separation box. Fine solid debris is easily trapped in the mesh after being squeezed by the extrusion plate, and the mesh blockage cannot be cleaned, thus making it impossible to ensure the normal passage of urine and maintain continuous separation operation. Therefore, this invention proposes a pig manure water separator and a pig manure sewage treatment device.

[0034] The compression assembly also includes: a slide bar 74, a spring 75, a fixing plate 76, and a buffer pad 77.

[0035] A slide rod 74 is fixedly mounted at the end of the screw 73, and the slide rod 74 and the mounting plate 10 are horizontally slidably connected. The slide rod 74 is fixed at the end of the screw 73 and slides horizontally along the mounting plate 10, limiting the movement direction of the extrusion plate 7.

[0037] A feeding hopper 11 is located at the bottom of the separation chamber 3. The feeding hopper 11 is arranged at the bottom of the separation chamber 3 to collect the separated water and pig manure, and to collect the materials for subsequent processing. A discharge pipe is installed on the feeding hopper 11 to transport the materials collected in the feeding hopper 11 to the outside, completing the discharge operation.

[0038] The functional principle of this invention can be explained through the following operational methods: When in use, pig manure is transported to the separation chamber 3 via the conveying unit 2. The base frame 1 bears the weight of the entire device. During the separation of pig manure moisture, the motor 52 starts to drive the screw 53 to rotate. The moving block 9 slides horizontally along the side groove 92. The connecting shaft 91 drives the toothed roller 5 to move horizontally and rotate synchronously. The toothed roller 5 meshes with the toothed hole 41 to squeeze and remove the internal blockage.

[0039] When maintenance or replacement of spring 75 is required, screw screw 73 to separate it from sleeve 71, remove sleeve 71 from separation chamber 3, and then remove spring 75, which is sleeved on slide rod 74, from between mounting plate 10 and outer ring 72. Perform maintenance or replace spring 75 directly. After replacement, reassemble all parts to ensure stable extrusion pressure when extruding pig manure with extrusion plate 7, and ensure that subsequent extrusion operations can be carried out continuously and stably.

[0040] The extrusion plate 7 works together to complete the extrusion of pig manure. The water inside the pig manure seeps downward through the toothed holes 41 on the filter plate 4 and is transported outward through the discharge pipe. The solid material is discharged after being extruded by the extrusion plate 7. The conveying unit 2 continuously transports the pig manure to be processed. The base frame 1 keeps the device running stably, achieving the effect of separating the water in the pig manure and smooth material transportation.
