Description

Technical Field

[0001] This utility model relates to the field of livestock and poultry breeding waste treatment technology, specifically to a gravity-type manure solid-liquid separation device. Background Technology

[0002] With the rapid development of livestock and poultry farming, the harmless treatment and resource utilization of livestock waste are receiving increasing attention. In manure treatment processes, solid-liquid separation is a crucial pretreatment step, which can effectively reduce the load on subsequent treatment facilities and facilitate the production of organic fertilizer and the discharge of wastewater in compliance with standards.

[0003] Currently, most mainstream manure solid-liquid separation equipment on the market (such as screw extruders) are designed to meet the needs of large-scale farms. These devices typically have complex structures and require high-power motors as a power source. They achieve solid-liquid separation of manure through the strong extrusion action generated by mechanical devices. Although they have a large processing capacity and good separation effect, they have high equipment purchase costs, high operating energy consumption, and a large footprint.

[0004] However, in actual industry, there are still a large number of small-scale, scattered farms. These farms are characterized by small scale, relatively low daily manure production, and dispersed distribution. For these small-scale farmers, using the aforementioned high-powered industrial-grade solid-liquid separators is overkill; not only is the initial investment too high, but the daily operating electricity and maintenance costs are also prohibitive. Currently, there is a lack of a dedicated manure separation device for small-scale farms that is simple in structure, low in cost, and requires no additional power. Therefore, there is an urgent need to develop a simple device that can utilize the fluid's own gravity and impact force for physical separation to fill this market gap. Utility Model Content

[0005] The purpose of this invention is to provide a gravity-type manure solid-liquid separation device to solve the problems of existing manure solid-liquid separators, which usually require high-power motors for driving and rely on strong extrusion for separation, resulting in high energy consumption and cost, and are not suitable for small-scale farms with low daily output.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A gravity-type fecal solid-liquid separation device includes: a high pad, a low pad, a separation plate assembly, and a collection tank assembly; The separation plate assembly is mounted at an angle, with its high end supported on a high plate and its low end supported on a low plate. The separation plate assembly includes a plate body and a plurality of separation prisms arrayed on the surface of the plate body; The collection tank assembly includes a liquid collection tank disposed below the plate body and corresponding to the gap between the separating prisms, and a solid collection tank disposed below one side of the plate body.

[0007] Furthermore, the high pad is composed of several pads stacked together, and the height can be adjusted by increasing or decreasing the number of pads; the low pad is fixedly set on the ground or support surface.

[0008] Furthermore, the plate has a trapezoidal plate structure, with the large end of the plate mounted on a high pad and the small end mounted on a low pad; long baffles, short baffles, and bottom baffles are fixed to the two side edges and the bottom edge of the plate, respectively, and the long baffles, short baffles, and bottom baffles form a semi-enclosed flow guide surface.

[0009] Furthermore, the upper surface of the plate is provided with several slots with a gap between them; the separation rib is embedded and fixed in the slots, and the extension direction of the separation rib is set at an angle to the tilt direction of the plate.

[0010] Furthermore, the cross-section of the separating prism has an inverted trapezoidal structure; the height and width of several separating prisms are gradually distributed along the transverse and longitudinal directions of the plate, wherein the height of the separating prisms located on the feed side and the first side is lower than the height of the separating prisms located on the second side, and the width of the separating prisms located on the feed side and the first side is smaller than the width of the separating prisms located on the second side.

[0011] Furthermore, the liquid collection tank has a triangular tank structure, and a support leg is provided on one side of the bottom of the liquid collection tank, so that the liquid collection tank is tilted as a whole.

[0012] Furthermore, the solid collection tank has a trapezoidal tank structure and is located below the side of the plate in the inclined direction; the bottom of the solid collection tank is provided with a support foot, so that the solid collection tank is in an inclined state; the interior of the solid collection tank is provided with a partition plate for separating the space.

[0013] This utility model has the following beneficial effects: This utility model uses the natural impact force and gravity of the feed as a power source, without the need for motor drive, which significantly reduces the equipment manufacturing cost and operating energy consumption, making it very suitable for small-scale farms. Furthermore, by setting separation ribs with gradually varying height, width and angle on the plate, it can precisely control the flow rate and rolling trajectory of solids and liquids, which not only achieves solid-liquid separation, but also allows for coarse and fine classification of solids.

Detailed Implementation

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please refer to Figure 1 This embodiment provides a gravity-type fecal solid-liquid separation device, which consists of a high pad 1, a low pad 2, a separation plate assembly, and a collection tank assembly.

[0018] The high pad 1 is located at one end of the device (feed end). It is not a single piece but is composed of several independent pads stacked together. This design allows users to flexibly adjust the overall height of the component (e.g., within a range of 70-120cm) by increasing or decreasing the number of pads, thereby changing the tilt angle of the subsequent separation plate to adapt to the treatment needs of feces with different viscosities. The low pad 2 is fixedly installed on the ground or on the other side support surface, providing stable support.

[0019] The separation plate assembly is crucial for achieving solid-liquid separation. It comprises a plate body 3 and several separation ribs 4 mounted on the plate body. The plate body 3 has a trapezoidal plate structure, with its wider end resting on a high pad 1 and its narrower end resting on a low pad 2, thus creating an inclined slope between the plate body 3 and the ground. To prevent the mixture from overflowing during pouring, long baffles 6, short baffles 7, and a bottom baffle 8 are fixedly installed on the two side edges and the bottom edge of the plate body 3, respectively. These three baffles enclose a semi-enclosed flow channel.

[0020] On the upper surface of the plate 3, several parallel or angled slots 5 are provided. A gap (e.g., 2-5 cm) is left between the slots 5 to allow liquid to pass through. The separating prism plate 4 is embedded and fixed within these slots 5.

[0021] To achieve a precise separation effect, the separation prism 4 is not a uniform structure. The cross-section of the separation prism 4 is an inverted trapezoidal structure (i.e., top to bottom), a shape that facilitates cutting the fluid and guiding the solid to roll. The height and width of several separation prisms 4 exhibit a "gradual change in both the transverse and longitudinal directions" distribution pattern on the plate body 3. Specifically, the side adjacent to the feed and the plate body is defined as the "first side" (e.g., side A), and the side furthest from the feed and the plate body is defined as the "second side" (e.g., side B). The separation prisms 4 located on the first side are designed to be "lower" and "thinner"; while those closer to the second side gradually become "higher" and "thicker".

[0022] The collection tank assembly is divided into two parts based on the form of the separated material: The liquid collection tank 9 is located directly below the plate 3 and is used to collect liquid dripping through the gap in the slot 5. It has a triangular tank structure and a support foot 11 on one side of the bottom to keep the whole structure tilted, which facilitates the liquid to collect and flow out.

[0023] The solid collection trough 10 is located below the inclined side of the plate 3 (i.e., corresponding to the "second side" / B side mentioned above). It has a trapezoidal trough structure and is also kept inclined by the support legs 11 to facilitate the rolling collection of solids. Inside the solid collection trough 10, there is also a partition plate 12 to further separate the solids of different sizes (coarse slag and fine slag) that roll down.

[0024] The specific working principle of this utility model is as follows: This device requires no motor drive and works entirely by utilizing the gravity and impact force of the fluid.

[0025] First, adjust the number of layers of the raised platform 1 according to the consistency of the feces to be treated, and set the tilt angle of the platform 3.

[0026] Then, the solid-liquid mixture of feces is continuously poured in from the high end (large opening end) of plate 3, and the impact force generated by the pouring is used to flush the mixture down the slope.

[0027] As the mixture flows over the surface of plate 3, the liquid portion is subjected to gravity and passes directly through the gap between the separating prisms 4 (i.e., the area between the slots 5), dripping into the liquid collection tank 9 below.

[0028] Solid particles cannot pass through the gaps and are blocked by the separating prism 4. Since the height and width of the separating prism 4 gradually change (from thinner to coarser), smaller solid particles may be intercepted and redirected on the first side (lower prism area), while larger solid particles will roll to the second side (higher prism area) and be intercepted. Under the combined influence of gravity and the guiding force of the separating prism 4, the solid material will roll diagonally downwards along the separating prism 4, eventually falling into the solid collection trough 10 below.

[0029] During the rolling process, fine and coarse solids will roll into different areas of the solid collection tank 10 in sequence due to their different inertia and degree of resistance. The solids can be classified into coarse and fine grades by using the partition plate 12 in the tank.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
