Description

Technical Field

[0001] This utility model relates to the field of livestock wastewater treatment technology, and in particular to a waste liquid treatment device for cattle farms. Background Technology

[0002] Cattle farming is an important part of modern agriculture, mainly divided into beef cattle farming and dairy cattle farming. It has high economic value and market demand, with significant economic benefits. The market demand for products such as beef and milk is stable, resulting in considerable profits for farmers. Further processing can increase added value, such as producing dairy products and leather goods, extending the industrial chain. With technological advancements, scientific breeding and standardized management have further improved the slaughter rate and quality of cattle, creating higher returns for farmers. With the rapid development of my country's livestock industry, poultry and livestock farming has become increasingly standardized, typically characterized by large-scale, centralized farming. While this large-scale, centralized farming method allows for better management of poultry and livestock, the disposal of cattle excrement in cattle farms remains a crucial issue that needs to be addressed. Otherwise, it can easily pollute the surrounding environment, which is detrimental to environmental protection.

[0003] The waste generated by cattle farms mainly includes cattle manure and livestock wastewater. Cattle manure is relatively easy to collect and process due to its solid nature, and can usually be effectively recycled and utilized. After composting and fermentation, cattle manure can be transformed into high-quality organic fertilizer, which can improve soil structure and increase crop yields. However, the wastewater from farms (mainly urine and a small amount of flushing water) has a high water content and is inconvenient to treat. Many farms, especially small and medium-sized farms, often lack effective wastewater utilization and treatment measures and usually discharge the wastewater directly into the surrounding environment. The wastewater contains a large amount of usable organic matter and nutrients. Direct discharge not only wastes resources but also easily pollutes the environment. At the same time, the wastewater often contains solid impurities such as mud, gravel, and food scraps. Existing technologies lack effective solid-liquid separation measures for the wastewater, which affects the efficiency of subsequent utilization and treatment.

[0004] Therefore, it is necessary to provide a wastewater treatment device for cattle farms to solve the above-mentioned technical problems. Utility Model Content

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Please see Figure 1-7This utility model provides a waste liquid treatment device for cattle farms, including a treatment box 4. Partitions a9 and b11, arranged vertically, are fixed on the inner wall of the treatment box 4. Multiple through holes c10 and d12 are respectively opened on the sides of partitions a9 and b11. An adjusting assembly 1 for opening and closing the through holes c10 and d12 is provided inside the treatment box 4. An adjusting assembly 2 for moving and adjusting partitions a9 and b11 is provided outside the treatment box 4. A feed pipe 15 communicating with the inside of the treatment box 4 is fixed to the top of the treatment box 4. During use, the feed pipe 15 can be connected to an external conveying system. The pump, through the feed pipe 15, introduces waste liquid from the cattle farm into the treatment tank 4. The liquid first falls onto the partition a9, where it undergoes preliminary coarse filtration through the through-holes c10, removing larger solid impurities and achieving solid-liquid separation. This effectively reduces the amount of solid impurities in the waste liquid. Smaller solid impurities mixed in with the liquid flow through multiple through-holes c10 to the bottom of the partition a9 for sedimentation. After a certain sedimentation period, the solid impurities in the waste liquid are deposited at the bottom of the treatment tank 4 through multiple through-holes d12. The regulating component 2 drives the regulating and closing component 1 to close the through-holes c10 and... By sealing the through-hole d12, the solid impurities at the bottom of the treatment tank 4 are isolated from the liquid in the middle of the tank, further separating the solids and liquids. This significantly reduces the amount of solid impurities in the waste liquid and improves its purity. Simultaneously, by isolating the solid impurities at the bottom of the treatment tank 4 from the waste liquid, it is easier to clean and discharge the impurities deposited there. This allows for closed fermentation of the waste liquid in the middle of the treatment tank 4. The cow urine waste liquid is rich in urea and organic acids, and after anaerobic fermentation, it can produce biogas. The farm can use the biogas for power generation or heating, saving energy and enabling the reuse of the waste liquid, greatly reducing waste and indiscriminate discharge that harms the environment. Pollution is eliminated, which aligns with the green concept of sustainable development. In this process, the added component 3 evenly delivers liquid containing biocatalysts into the waste liquid. For example, by adding highly efficient anaerobic bacteria such as Methanococcus methanans and Methanotherium methanogens, the methanogenic pathway can be directly enhanced, shortening the fermentation start-up time. Secondly, by adding compound enzyme preparations including cellulase, protease, and lipase, the complex organic matter in urine can be decomposed more quickly, converting it into easily fermentable small molecules. By evenly adding biocatalysts to the waste liquid, biogas production and fermentation efficiency are effectively increased, thereby improving the overall efficiency and quality of waste liquid utilization and treatment.

[0030] Further as Figure 3 , Figure 5 and Figure 6As shown, it is worth noting that the regulating assembly 1 includes a movable plate b103 and a movable plate a101 respectively attached to the side of the partition a9 and the side of the partition b11. The movable plate b103 has multiple through holes b104 corresponding to through holes c10 on its side, and the movable plate a101 has multiple through holes a102 corresponding to through holes d12 on its side. In operation, when waste liquid is added to the treatment tank 4, through holes c10 and b104 are aligned, and through holes d12 and a102 are aligned. At this time, through holes c10 and d12 are open, allowing waste liquid to enter the middle of the treatment tank 4 through through hole c10, and solid impurities to deposit at the bottom of the treatment tank 4 through through hole d12. After the solid impurities in the waste liquid are separated by deposition, the movable plates b103 and a101 are moved synchronously to adjust the alignment of through holes b104 and b102. 0. Through holes d12 and a102 are completely misaligned. Sealing rubber gaskets are installed between the moving plate b103 and the partition a9, and between the partition b11 and the moving plate a101. Thus, the moving plates b103 and a101 seal the through holes c10 and d12, thereby isolating and separating the solid impurities at the bottom of the treatment tank 4 from the liquid in the middle of the treatment tank 4, further separating solids and liquids, greatly reducing solid impurities in the waste liquid, and improving the purity of the waste liquid. At the same time, by isolating the solid impurities at the bottom of the treatment tank 4 from the waste liquid, it is easy to clean and discharge the impurities deposited at the bottom of the treatment tank 4, and realize the closed fermentation of the waste liquid in the middle of the treatment tank 4. The cow urine waste liquid is rich in urea and organic acids, and can produce biogas after anaerobic fermentation. The farm can use the biogas for power generation or heating, saving energy, realizing the reuse of waste liquid, and greatly reducing waste and pollution to the environment caused by random discharge.

[0031] Further as Figure 3 , Figure 4 and Figure 6 As shown, it is worth noting that the adjustment assembly 2 includes a threaded rod 201 rotatably connected to the outer wall of the processing box 4. Connecting rods a204 are fixed to the same side ends of both the moving plate b103 and the moving plate a101. A connecting plate 205 located outside the processing box 4 is fixed to the ends of both connecting rods a204. A nut sleeve 202, threadedly engaged with the threaded rod 201, is fixed inside the connecting plate 205. In operation, rotating the adjusting threaded rod 201 causes the connecting plate 205 to move and adjust due to the threaded engagement between the threaded rod 201 and the nut sleeve 202. The connecting plate 205 then drives the two connecting rods a204 to move synchronously, thereby achieving synchronous movement adjustment of the moving plate b103 and the moving plate a101, and thus opening and closing the through hole c10 and the through hole d12.

[0032] Further as Figure 6As shown, it is worth noting that a handle rod 203 is fixed to the end of the threaded rod 201, and a rubber sleeve is fitted onto the surface of the handle rod 203; in actual operation, the threaded rod 201 can be easily rotated and adjusted by the handle rod 203, which facilitates operation.

[0033] Further as Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, it is worth noting that the regulating and closing component 1 is internally equipped with an adding component 3. The adding component 3 includes multiple feeding holes 301 inside the moving plate a101, which are equidistantly distributed. The moving plate a101 has feeding holes 301 on its side near the partition b11 that communicate with the cavity 303. A conveying pipe 302 communicating with the cavity 303 is fixed on the moving plate a101. During the waste liquid fermentation process, the feeding holes 301 on the moving plate a101 are aligned with the through hole d12. The conveying pipe 302 is connected to a liquid pump, which transports the liquid containing the biocatalyst into the cavity 303 through the conveying pipe 302. The liquid is then evenly sprayed into the waste liquid through the multiple feeding holes 301, effectively improving the uniformity of mixing between the biocatalyst and the waste liquid, increasing the efficiency of uniform mixing between the biocatalyst and the waste liquid, shortening the fermentation start-up time, effectively increasing biogas production and fermentation efficiency, and further improving the overall efficiency and quality of waste liquid utilization and treatment.

[0034] Further as Figure 5 As shown, it is worth noting that a push plate 13 is provided at the bottom of the processing box 4. A connecting rod b14 that slides through the side wall of the processing box 4 is fixed on the side of the push plate 13. A discharge port 8 is provided on the side wall of the processing box 4, and a cover plate 7 is hinged inside the discharge port 8. In actual operation, by pulling the connecting rod b14, the push plate 13 is pushed to move at the bottom of the processing box 4, and the cover plate 7 is opened. Thus, the solid impurities at the bottom of the processing box 4 can be cleaned and discharged through the discharge port 8 by the push plate 13, which is convenient for cleaning.

[0035] This solution has the following working process: When waste liquid is added into the treatment tank 4, through holes c10 and b104 are aligned, and through holes d12 and a102 are aligned. At this time, through holes c10 and d12 are in the open state, and the waste liquid can enter the middle of the treatment tank 4 through through hole c10. Solid impurities can be deposited at the bottom of the treatment tank 4 through through hole d12. After the solid impurities in the waste liquid are separated by deposition, the adjusting threaded rod 201 is rotated. The threaded engagement between the threaded rod 201 and the nut sleeve 202 drives the connecting plate 205 to move and adjust. The connecting plate 205 drives the two connecting rods a204 to move synchronously, thereby realizing the synchronous movement adjustment of the moving plate b103 and the moving plate a101. This makes the through holes b104 and c10, and through holes d12 and a102 completely misaligned. There are gaps between the moving plate b103 and the partition a9, and between the partition b11 and the moving plate a101. A sealing rubber gasket is installed, thereby sealing the through holes c10 and d12 through the moving plates b103 and a101, thus isolating and separating the solid impurities at the bottom of the treatment tank 4 from the liquid in the middle of the treatment tank 4. This facilitates the cleaning and discharge of impurities deposited at the bottom of the treatment tank 4, enabling the closed fermentation of the waste liquid in the middle of the treatment tank 4. After anaerobic fermentation, biogas can be produced for reuse. The liquid containing the biocatalyst is transported into the cavity 303 through the conveying pipe 302 and evenly sprayed into the waste liquid through multiple feeding holes 301, improving the uniform mixing efficiency of the biocatalyst and waste liquid, shortening the fermentation start-up time, and increasing biogas production and fermentation efficiency. By pulling the connecting rod b14, the push plate 13 is moved at the bottom of the treatment tank 4, opening the cover plate 7, so that the solid impurities at the bottom of the treatment tank 4 can be cleaned and discharged through the discharge port 8 through the push plate 13.

[0036] Further as Figure 1 As shown, it is worth noting that the top of the treatment box 4 is hinged with a cover plate that can seal the top opening of the treatment box 4. An exhaust pipe 16 that communicates with the inside of the treatment box 4 is fixed to the top of the cover plate. By opening the cover plate on the top of the treatment box 4, it is convenient to clean the larger solid impurities on the top of the partition a9. A valve is installed on the exhaust pipe 16. By opening the valve, the biogas produced by the waste liquid inside the treatment box 4 can be collected and utilized through the exhaust pipe 16.

[0037] Further as Figure 3 and Figure 4 As shown, it is worth noting that rubber sleeves 206 are provided between the connecting rod a204 and the side wall of the treatment tank 4, and between the conveying pipe 302 and the side wall of the treatment tank 4; the rubber sleeves 206 improve the sealing performance and prevent leakage of waste liquid.

[0038] In summary: By using the regulating component 2 to drive the closing component 1 to seal through holes c10 and d12, the solid impurities at the bottom of the treatment tank 4 and the liquid in the middle of the treatment tank 4 are isolated and separated, further reducing solid impurities in the waste liquid and improving its purity. Simultaneously, by isolating the solid impurities at the bottom of the treatment tank 4 from the waste liquid, it is easier to clean and discharge the impurities deposited at the bottom of the treatment tank 4. This allows for the closed fermentation of the waste liquid in the middle of the treatment tank 4. The cow urine waste liquid is rich in urea and organic acids, and after anaerobic fermentation, it can produce biogas. The farm can use the biogas for power generation or heating, saving energy and realizing the reuse of the waste liquid. This significantly reduces waste and indiscriminate discharge, aligning with the green concept of sustainable development. In this process, the added component 3 evenly delivers liquid containing biocatalysts into the wastewater. For example, adding highly efficient anaerobic bacteria such as *Methanococcus methanans* and *Methanococcus faecium* directly enhances the methanogenesis pathway and shortens fermentation start-up time. Secondly, adding compound enzyme preparations, including cellulase, protease, and lipase, accelerates the decomposition of complex organic matter in urine, converting it into easily fermentable small molecules. By evenly adding biocatalysts to the wastewater, biogas production and fermentation efficiency are effectively increased, thereby improving the overall efficiency and quality of wastewater utilization and treatment.
