Abstract
Description
Technical Field
[0001] This utility model relates to the field of livestock waste treatment technology, specifically to a resource-based treatment device for livestock farm waste. Background Technology
[0002] During the breeding process, a large amount of waste is generated. This waste contains a large amount of organic matter, nitrogen, phosphorus, potassium and other nutrients. If it is not treated in time or is directly discarded, it may lead to water quality deterioration, damage to air quality, respiratory diseases, and damage to soil structure, affecting crop growth. Moreover, untreated waste can also breed foul odors and mosquitoes and flies, spreading diseases.
[0003] Solid-liquid separation of waste is a crucial step in waste treatment, separating the solid and liquid components to facilitate subsequent processing and resource utilization. Current methods for solid-liquid separation typically involve filtration using filters. However, simply using filters can only remove a portion of the liquid, resulting in ineffective solid-liquid separation. Summary of the Invention

[0012] As an improvement, an exhaust pipe is connected to the top of the hydraulic chamber.
[0013] As an improvement: the bottom of the liquid collection tank is connected to a drain pipe with a valve, the bottom of the processing tank has a perforation that matches the drain pipe, and one side of the liquid collection tank has an observation window.
[0014] (III) Beneficial Effects
[0015] The advantages of this utility model compared with the prior art are as follows:
[0016] Solid-liquid mixed waste is initially separated through a filter screen, and then the hydraulic cylinder acts on the extrusion plate to perform a pressure filtration operation on the initially filtered solid waste. At the same time, the heating box raises the temperature in the hydraulic chamber to dry the solid waste, thereby improving the solid-liquid separation effect and facilitating subsequent processing.
[0017] The filter chamber is equipped with crushing blades, which are driven by a motor to rotate and crush larger solid wastes into smaller ones. This not only facilitates subsequent filtration of the waste using a hydraulic cylinder, but also helps to improve the degradation efficiency of organic matter, thereby improving the quality of subsequent composting.

[0027] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagrams, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0028] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0029] Combined with appendix Figure 3 As shown, a waste resource utilization device for livestock farms includes a processing box 1. The top of the processing box 1 is provided with a feed inlet 2. The processing box 1 is connected to a filter chamber 3, a hydraulic chamber 4 and a recovery chamber 5. The recovery chamber 5 is located below the filter chamber 3 and the hydraulic chamber 4. The hydraulic chamber 4 is located slightly below one side of the filter chamber 3.
[0030] Combined with appendix Figure 3 As shown, a rotating shaft 6 is rotatably installed inside the filter chamber 3, and a motor is installed on the processing box 1. The rotating shaft 6 is connected to the output end of the motor to drive the rotating shaft 6 to rotate. Multiple sets of crushing blades 7 are equidistantly arranged on the rotating shaft 6. A splash guard 13 is installed inside the filter chamber 3 outside the crushing blades 7, and the bottom of the splash guard 13 has an inverted conical structure. The splash guard 13 can prevent the waste from splashing and causing uneven crushing when the crushing blades 7 crush solid waste.
[0031] Combined with appendix Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, an inclined filter screen 8 is provided below the crushing blade 7. An inclined plate 14 is fixedly provided at the opening connecting the filter chamber 3 and the hydraulic chamber 4. The end of the inclined plate 14 near the filter chamber 3 is higher than the end near the hydraulic chamber 4. A fixed plate is provided on the side wall of the filter chamber 3 opposite to the inclined plate 14. Both the fixed plate and the inclined plate 14 are provided with sliding grooves 15. The filter screen 8 is inserted between the two sliding grooves 15, and the inclination angle of the filter screen 8 is the same as the inclination angle of the inclined plate 14. The filter screen 8 and the inclined plate 14 cooperate to form a slope, so that solid waste can slide down the slope into the hydraulic chamber 4.
[0032] Combined with appendix Figures 1 to 3 As shown, a solid collection box 9 is pulled out inside the hydraulic chamber 4. The bottom surface of the solid collection box 9 is provided with a uniform array of leakage holes 16. A heating box 17 is provided on the outer wall of the processing box 1. The heating boxes 17 are located on both sides of the hydraulic chamber 4 and are provided with electric heating tubes. The heating boxes 17 raise the temperature inside the hydraulic chamber 4 through the electric heating tubes, thereby drying the solid waste. Hydraulic cylinders 11 are symmetrically provided on the top of the hydraulic chamber 4. The extension and retraction ends of the hydraulic cylinders 11 are connected to the extrusion plates 12. An exhaust pipe 18 is connected to the top of the hydraulic chamber 4. The exhaust pipe 18 is used to exchange the air inside and outside the hydraulic chamber 4 to avoid excessive air pressure inside the hydraulic chamber 4 due to temperature rise.
[0033] Combined with appendix Figure 1 and Figure 5 As shown, a liquid collection tank 10 for collecting waste liquid is pulled out inside the recycling chamber 5. A drain pipe 19 is connected to the bottom of the liquid collection tank 10, and a valve is provided on the drain pipe 19. The valve is used to control whether the liquid is discharged. A perforation 20 that cooperates with the drain pipe 19 is opened at the bottom of the processing tank 1. An observation window 21 is provided on one side of the liquid collection tank 10.
[0034] First, a filter cloth is laid at the bottom of the solid collection box 9. The solid-liquid mixed waste is put into the feed inlet 2 and first enters the splash shield 13. The motor drives the crushing blade 7 to rotate and crush the solid waste. The liquid waste enters the liquid collection box 10 below through the filter screen.
[0035] The crushed solid waste falls onto the filter screen 8. Since the filter screen 8 is set at an angle, the solid waste slides down its slope into the solid collection box 9. At this time, the electric heating tube heats up the temperature in the hydraulic chamber 4. When the amount of waste in the solid collection box 9 reaches a certain amount, the hydraulic cylinder 11 is activated, and the extrusion plate 12 descends to perform a pressure filtration operation on the solid waste. The waste liquid in the liquid collection box 10 can be discharged through the drain pipe 19.
[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
