Description

Technical Field

[0001] This utility model relates to the field of ecological aquaculture technology, and in particular to a fecal solid-liquid separation device for ecological aquaculture. Background Technology

[0002] In ecological farming, the treatment of livestock and poultry manure is crucial for environmental protection and resource utilization. However, traditional manure treatment methods often fail to effectively separate solids and liquids, leading to environmental pollution and resource waste. Existing separation devices suffer from problems such as poor separation efficiency, complex operation, and inability to perform separation operations according to the state of animal manure.

[0003] For example, patent document CN212356988U discloses a solid-liquid separation device for ecological aquaculture. This device uses rollers to fix the frame, the transmission box is driven by a motor, and the separation box rotates via a connecting shaft. The transmission gears interact with the transmission gears, and the linkage plate moves the vibrating rod. Solid manure is fed into the hopper, and water pressure is provided by the inlet pipe. Water nozzles perform preliminary separation and dilution of the manure. The connecting shaft rotates the conveyor plate, further separating the manure within the separation box. The manure is discharged through the discharge plate, and wastewater is discharged from the drain outlet of the separation box.

[0004] The treatment methods for different types of biological excrement vary, and the aforementioned patent is limited to solid-liquid separation of excrement from the same type of animal, failing to make appropriate adjustments based on the specific characteristics of various animal excrements. For solid excrement with low water content, it can be used as fertilizer or soil conditioner; while for solid excrement with high water content, it can be composted or used for biomass power generation.

Therefore, they should not be construed as limitations on this utility model.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5As shown, an ecological livestock manure solid-liquid separation device includes ten support legs 101, a frame plate 102, and a squeezing mechanism 4. The frame plate 102 is welded to the top of the support legs 101, and a power mechanism 2 is installed at the top of the frame plate 102. A support frame 301 is bolted to the top of the frame plate 102, and a shell 302 is welded to the top of the support frame 301. A front cover plate 303 is bolted to the front end of the shell 302, and a drain pipe 310 is welded to the bottom end of the front cover plate 303. A feed box 304 is welded to the top of the shell 302, and the squeezing mechanism 4 is installed inside the shell 302. A guide pipe 501 is welded to the rear end of the shell 302, and the rear end of the guide pipe 501 is slidably connected to... There is a guide shaft 502, and an adjusting nut 505 is threaded to the rear end of the guide shaft 502. An adjusting spring 503 is welded to the inner side of the rear end of the guide tube 501. An adjusting pressure plate 504 is welded to the front end of the adjusting spring 503. The rear end of the adjusting pressure plate 504 is welded to the guide shaft 502. The adjusting spring 503 is sleeved on the guide shaft 502. A discharge pipe 506 is welded to the bottom end of the guide shaft 502. The feces are first introduced into the feed box 304 and then into the outer shell 302. During this process, the squeezing mechanism 4 is responsible for performing the dry and wet separation of the feces. The separated solid feces are discharged through the discharge pipe 506, while the liquid part is discharged through the liquid discharge pipe 310.

[0026] A return pipe 308 is welded to the rear end of the feed box 304. A filter screen 305 is bolted to the top of the feed box 304. A feed pipe cover plate 306 is bolted to the top of the filter screen 305. A feed pipe 307 is welded to the top of the feed pipe cover plate 306. After the feces enter, they first pass through the feed pipe 307 and then flow through the filter screen 305 for preliminary separation. Then they flow into the feed box 304. At the same time, a return pipe 308 is provided on the feed box 304. When the amount of feces input is too large, or when there is still accumulation caused by feces that has not been completely separated into dry and wet parts, an overflow effect is achieved.

[0027] The extrusion mechanism 4 includes an auger shaft 401, a conical auger tube 402 welded to the auger shaft 401, a spiral auger blade 403 welded to the conical auger tube 402, and five detachable filter plates 404 bolted to the conical auger tube 402. The detachable filter plates 404 are arranged in a circumferential array on the conical auger tube 402. After the feces are input, they are extruded by the extrusion mechanism 4 and continuously conveyed to the discharge pipe 506 under the drive of the spiral auger blade 403. Since the outer shell 302 is conical, it is continuously compressed during the backward transmission. The compressed liquid flows out through the inner wall of the conical auger tube 402 and into the discharge pipe 310.

[0028] The power mechanism 2 includes an electric motor 201. The output end of the electric motor 201 is bolted to a reducer 202. The bottom end of the reducer 202 is bolted to the frame plate 102. The output end of the reducer 202 is keyed to a first pulley 203. A V-belt 204 is fitted on the first pulley 203. A second pulley 205 is fitted on the other end of the V-belt 204. One end of the second pulley 205 is keyed to the auger shaft 401.

[0029] A second sealing plate 312 is welded to the inner front end of the outer casing 302, and a first sealing plate 311 is welded to the inner rear end of the front cover 303. When the liquid after dry and wet separation flows out, the presence of the second sealing plate 312 ensures that the separated liquid will not flow out of the outer casing 302 during the squeezing process, and the presence of the first sealing plate 311 ensures that the separated liquid will not flow out from the rear side of the front cover 303.

[0030] A support shaft plate 309 is welded to the inner wall of the rear end of the outer casing 302, and the auger shaft 401 is rotatably connected to the support shaft plate 309.

[0031] Working Principle: Feces are introduced through the feed pipe 307 and undergo preliminary separation at the filter screen 305 to remove larger impurities such as hair. After being processed by the filter screen 305, the feces then enter the outer casing 302. At this time, the motor 201 starts, and its power is reduced in speed by the reducer 202 before being transmitted to the first pulley 203. The first pulley 203 transmits power to the second pulley 205 via the V-belt 204, and the second pulley 205 rotates in conjunction with the auger shaft 401. The auger shaft 401 drives the conical auger tube 402, the spiral auger blades 403, and the detachable filter plate 404 to rotate. The rotational motion of the extrusion mechanism 4 gradually compresses the solid feces, which first contact the adjusting pressure plate 504. When the solid feces accumulate to a certain amount, the adjusting spring 503 is compressed, causing the adjusting pressure plate 504 to move backward. Solid feces are then discharged through discharge pipe 506, while liquid feces flow into the pipe through five detachable filter plates 404 on the inner wall of the conical auger pipe 402, and then flow through the internal space of the conical auger pipe 402 to discharge through drain pipe 310. For different types of feces or solid feces with different moisture requirements, the compression degree of the adjusting spring 503 can be controlled by adjusting nut 505, thereby adjusting the initial pressure to obtain solid feces with different moisture contents.

[0032] 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 claimed utility model.
