Abstract
Description
Technical Field
[0001] This utility model belongs to the field of livestock farm manure treatment technology, and in particular relates to an in-situ storage device for livestock farm manure. Background Technology
[0002] Currently, dry manure cleaning technology is being promoted in various regions as a method for cleaning manure in livestock and poultry farms. This involves diverting livestock and poultry manure to sloping collection ditches, then using manure scrapers or manual scraping to collect the manure into manure pits for centralized treatment. Dry manure cleaning is a quick and effective way to clean manure in poultry houses, requiring simple equipment. It not only reduces water consumption but also effectively prevents the foul odors produced by the natural fermentation of manure, maintaining a good environment inside the houses.
[0003] For manure removed by dry manure cleaning processes, the current conventional method in most farms is to build manure pits near the livestock sheds and clean them periodically by manual removal or pumping. This approach has the following technical drawbacks:
[0004] (1) When manual cleaning is used, the septic tank is built shallower, occupies a large area, has a small volume, and requires frequent cleaning in order to cooperate with manual work. If the supply of personnel is not timely, it will easily cause environmental pollution problems.
[0005] (2) When using a pump to pump manure, the manure pit is generally a large rectangular or circular open pit. The pump is placed in a corner of the manure pit and a large amount of water is required to ensure that the pump can pump manure. However, the large amount of water leads to increased solid-liquid separation and wastewater treatment volume at the back end, which increases the treatment cost. At the same time, since the manure pit is open, the manure emits foul odors without organization, which affects the environment and hygiene of the farm. In addition, for the conventional structure of rectangular or circular pit with the pump placed in a corner, there are many dead corners in the pit, and the pump is prone to blockage after long-term deposition of some large particles. Utility Model Content
[0006] The purpose of this invention is to overcome the defects of the existing technology and provide a farm manure in-situ storage device with low maintenance cost and good environmental benefits.
[0007] The objective of this utility model can be achieved through the following technical solutions:
[0008] This utility model provides an in-situ storage device for livestock manure, including a storage tank and a manure pump, as well as a diversion plate, a cover plate and a composite pipeline system. The vertical cross-section of the storage tank is an inverted trapezoid with a wider top and a narrower bottom. The manure pump is installed at the bottom of the storage tank, and the diversion plate is installed at an angle and connected to the manure outlet of the livestock house and the edge of the storage tank opening.
[0009] The composite pipeline system includes a sewage mixing and deodorization component. The sewage mixing and deodorization component share a pipeline pump. The sewage mixing and deodorization component includes multiple staggered jet nozzles, which are installed in groups at the bottom of the storage tank. The installation angles of the staggered jet nozzles in each group are different. The deodorization component includes multiple inverted umbrella-shaped multi-spined vortex nozzles, which are installed above the storage tank.
[0010] The cover is located above the deodorization component and covers the opening of the storage tank.
[0011] Furthermore, the top of the diversion plate is provided with rake teeth, the axial cross section of which is a three-segment broken line. The starting segment of the three-segment broken line is embedded inward from the top of the diversion plate, and the middle and ending segments of the three-segment broken line extend outward from the top of the diversion plate. There are multiple rake teeth, which are evenly distributed along the top edge of the diversion plate.
[0012] Furthermore, the included angle between the middle and end sections of the rake teeth is 135°, and the spacing between adjacent rake teeth is 0.9 times the equivalent diameter of large particles in the manure of the livestock and poultry being raised.
[0013] Furthermore, the rake teeth are made of threaded steel, with the diameter of the threaded steel ranging from 5 to 8 mm.
[0014] Furthermore, the staggered jet nozzles are installed in pairs, and the included angle between the two staggered jet nozzles in each pair is 60°.
[0015] Furthermore, the inverted umbrella-shaped multi-spined vortex nozzle includes multiple water spray holes arranged in a multi-layered annular pattern, with each annular water spray hole having a different spray angle relative to the central axis of the annulus.
[0016] Furthermore, the diameter of the water spray hole is 0.5-1mm.
[0017] Furthermore, the upper surface of the diversion plate is provided with a surface material, and the tilt angle of the diversion plate is greater than the minimum installation tilt angle. The minimum installation tilt angle is determined by the surface roughness of the surface material and the viscosity of the livestock and poultry manure. The size of the tilt angle is inversely proportional to the surface roughness of the surface material and directly proportional to the viscosity of the livestock and poultry manure.
[0018] Furthermore, the storage tank wall is a four-sided pyramid shape with a side wall inclination angle greater than or equal to 50°, and the bottom of the storage tank is equipped with a cone-shaped structure with an equivalent radius of the bottom less than or equal to 7 times the pump suction port radius of the septic tank pump.
[0019] Furthermore, the sewage mixing and deodorizing components are controlled by control valves.
[0020] Compared with the prior art, the present invention has the following advantages:
[0021] 1. This utility model proposes an in-situ manure storage device for livestock farms. After the manure in the livestock sheds is cleaned outside, it flows into the storage tank without power through a diversion plate. The storage tank utilizes the inverted trapezoidal structure, which is wider at the top and narrower at the bottom, to collect the manure at the manure pump. At the same time, the diversion plate has rake teeth to intercept large particles, eliminating dead corners for long-term sedimentation and effectively reducing the probability of pump blockage. After water is added and stirred in the composite porous pipe system, the manure pump periodically pumps the manure to the next stage of the treatment system. The composite pipe system includes a manure water addition and stirring system located at the bottom of the tank and a deodorization system located under the cover plate. The process of adding water and stirring the manure in the storage tank simultaneously achieves spray deodorization. The structure is simple, occupies a relatively small area, has a large volume, requires less frequent manure cleaning, and is convenient to operate and maintain.
[0022] 2. The storage tank adopts an inverted trapezoidal conical structure with a vertical cross-section that is wider at the top and narrower at the bottom. This allows fecal waste to naturally collect at the bottom of the tank where the septic pump is located, reducing dead corners and preventing the long-term accumulation of large particles. Simultaneously, the equivalent radius of the tank bottom is limited to within 7 times the radius of the septic pump's suction port, further optimizing the pump's suction efficiency. Multiple sets of paired, staggered jet nozzles are installed at the bottom of the tank. The angle differences between the different sets create swirling and turbulent flow, enhancing the mixing effect of fecal waste and water and reducing the amount of water injected.
[0023] 3. The top of the diversion plate is equipped with three sections of zigzag rake teeth made of rebar. The angle between the middle section and the end section is 135°, and the spacing is 0.9 times the equivalent diameter of large particles in the sewage. Through mechanical interception and directional flow, large particles are effectively separated to prevent them from entering the storage tank and clogging the pump body.
[0024] 4. The surface of the diversion plate is made of materials with different roughness (such as glossy glazed tiles, glass, etc.) to suit different types of livestock and poultry manure. The diversion plate has a minimum installation tilt angle, and the installation tilt angle of the diversion plate is controlled to be greater than the minimum installation angle. The minimum installation angle is determined by the surface roughness of the surface material (7) and the viscosity of the livestock and poultry manure. The relationship is: the installation tilt angle is inversely proportional to the surface roughness of the surface material (7) and directly proportional to the viscosity of the livestock and poultry manure. It realizes the non-powered diversion of manure, does not require supporting equipment for scraping, does not require power supply, the device is simple, energy-saving, and easy to operate and maintain.
[0025] 5. A composite piping system, comprising a sewage water mixing system located at the bottom of the tank and a deodorization system located under the cover. The water mixing system consists of groups of staggered jet nozzles, each group covering a specific area. The jet nozzles utilize swirling and turbulent flow design to achieve uniform mixing and prevent localized sedimentation. The deodorization system is equipped with inverted umbrella-shaped multi-spiked vortex nozzles, a non-atomizing system requiring only 0.6–1 MPa of pipeline pressure to guide water in a diffused spray pattern. This provides wide coverage, small droplet size, and a large contact area with odorous gases, resulting in good deodorization. The low pressure also reduces energy consumption compared to traditional high-pressure spray deodorization. A single pipeline pump can meet the needs of multiple tanks, reducing equipment purchase and maintenance costs. Valve control ensures that water supply to each tank's water supply system and water spraying to the deodorization system are distributed as needed, preventing pipeline pressure imbalance.
[0026] 6. This utility model provides a cover plate above the storage pool and composite pipeline system to block the volatilization of livestock and poultry manure odor and reduce the adverse effects caused by foul odor. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments 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. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0033] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0034] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0035] like Figure 1 As shown, this utility model relates to an in-situ storage device for livestock manure, including a storage tank 1, a diversion plate 2, a manure pump 3, a cover plate 5, and a composite pipeline system 4. After the livestock manure is cleaned outside the house, it flows into the storage tank 1 without power through the diversion plate 2. The storage tank 1 collects the manure to the manure pump 3. After water is added and stirred in the composite porous pipe system, the manure pump 3 periodically pumps the manure to the next stage of the treatment system. The composite porous pipe system sprays deodorization and, together with the cover plate 5, maintains the hygiene of the environment outside the livestock house. The diversion plate 2 has different slopes depending on the type of feces and the roughness of the surface material. The surface is made of a surface material 7 with a certain roughness, suitable for non-powered diversion of feces in various application scenarios. The top of the diversion plate 2 has rake teeth 6 to intercept large particles, effectively reducing the probability of pump blockage. The composite pipeline system 4 includes a feces-water mixing component and a deodorization component. The feces-water mixing component consists of multiple staggered jet nozzles 8, and the deodorization component consists of multiple inverted umbrella-shaped multi-spiked vortex nozzles 9. The feces-water mixing component and the deodorization component share a pipeline pump 10 and are controlled by control valves 11. The process of adding water and mixing feces in the storage tank 1 simultaneously achieves spray deodorization. Figure 2 As shown.
[0036] Specifically, the vertical cross-section of the storage tank 1 is an inverted trapezoid, wider at the top and narrower at the bottom. The manure pump 3 is installed at the bottom of the storage tank 1, and the diversion plate 2 is installed at an angle and connects the manure outlet of the livestock shed to the edge of the storage tank 1. Preferably, the storage tank 1 is a tetrahedral shape with a sidewall inclination angle greater than or equal to 50°. The bottom of the storage tank 1 has a conical structure, and the equivalent radius of the bottom is less than or equal to 7 times the suction port radius of the manure pump 3. This structure of the storage tank 1 and the arrangement of the manure pump 3 can solve the problems of large bottom area, many dead corners, and long-term accumulation of solid matter in conventional tanks, and the manure pump 3 is less prone to clogging.
[0037] Specifically, when the diversion plate 2 is installed at an angle, different tilt angles can be set according to the viscosity of different livestock and poultry manure and the roughness of the slope surface material 7, ensuring that the material can slide naturally down the slope without the need for supporting equipment or power supply, realizing non-powered manure diversion. The device is simple, energy-saving, and easy to operate and maintain. In addition, depending on the application scenario, materials with different roughness can be selected as the surface material 7 of the diversion plate 2, such as glossy glazed tiles, glass, and ceramic tiles, making it widely applicable.
[0038] Specifically, the top of the diversion plate 2 is provided with rake teeth 6 for intercepting large particles. In a preferred embodiment, the rake teeth 6 are made of φ5-φ8mm threaded steel, bent into a three-segment zigzag shape. The initial segment of the three zigzag segments is embedded inward from the top of the diversion plate 2, while the middle and final segments extend outward from the top of the diversion plate 2 at an angle of 135°. Furthermore, there are multiple rake teeth 6 evenly distributed along the top edge of the diversion plate 2. The spacing between adjacent rake teeth 6 is determined according to the type of livestock and poultry being raised, and is taken as 0.9 times the equivalent diameter of large particles in the manure of the livestock and poultry being raised.
[0039] Specifically, the composite pipeline system 4 includes a sewage mixing and deodorizing component and a sewage adding and mixing component, which share a pipeline pump 10. In a preferred embodiment, the pipeline pump 10 is a pipeline booster pump. The sewage mixing and mixing component includes multiple staggered jet nozzles 8 installed in groups at the bottom of the storage tank 1. In a preferred embodiment, the staggered jet nozzles 8 are installed in pairs, with the included angle between the two nozzles in each group being 60°. The installation angles of the staggered jet nozzles 8 differ between different groups. During jet mixing, the two nozzles in each group stagger at a 60° angle to form a vortex, enhancing the mixing effect; the staggered arrangement between different groups creates turbulence between different vortices, further strengthening the mixing effect of sewage and water.
[0040] In addition, the deodorization component includes multiple inverted umbrella-shaped multi-spiked vortex nozzles 9 installed above the storage tank 1. Each inverted umbrella-shaped multi-spiked vortex nozzle 9 includes multiple water spray holes arranged in a multi-layered annular pattern, with each layer having a different spray angle relative to the annular central axis. In a preferred embodiment, the water spray holes are small holes with a diameter of φ0.5-φ1mm. In this configuration, the multiple small holes are arranged in a multi-spiked inverted umbrella shape, with different holes arranged in multiple layers. The outlet directions of the holes in different layers are inconsistent. The pipeline pressure only needs to be 0.6–1 MPa to guide the water out in a diffused spray pattern, resulting in a wide water coverage area, small water droplet size, and a slightly larger contact area with odorous substances, leading to good deodorization. As a non-atomizing system, its energy consumption is lower than that of traditional high-pressure spray deodorization.
[0041] This utility model also includes a cover plate 5, which is located above the deodorizing component and covers the opening of the storage tank 1 to block the evaporation of livestock and poultry manure odor and reduce the adverse effects caused by malodor.
[0042] The entire storage unit occupies a small area, has a large capacity, can store manure for many days, and requires infrequent cleaning; it is odorless, aesthetically pleasing, and has minimal environmental impact due to its long-term storage of manure, resulting in good environmental benefits.
