Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment equipment technology, specifically to an integrated water treatment equipment for livestock farming. Background Technology
[0002] In the livestock farming industry, water resources are indispensable for everything from daily drinking water and pen cleaning and disinfection to feed preparation and manure flushing. The quality of water used in animal husbandry directly affects the healthy growth and production performance of livestock. For example, clean drinking water can reduce the chances of livestock getting sick and improve survival rate and product quality; while water used for cleaning needs to have a certain ability to remove pollutants and avoid causing secondary pollution to the farming environment.
[0003] According to the search, Chinese patent document CN216785889U discloses an integrated livestock breeding water treatment device. Livestock breeding wastewater is introduced into a solid-liquid separation tank through the inlet. Then, a filter screen on the separation device traps livestock manure and other waste in the wastewater at the left side of the solid-liquid separation tank. A precipitant is then poured in through the precipitant inlet, causing the livestock manure and other waste to settle, thereby improving the solid-liquid separation efficiency. Furthermore, the filter screen is installed in the upper middle part of the solid-liquid separation tank via a slot. When the filter screen needs to be replaced or cleaned, it can be directly removed from the solid-liquid separation tank using the handle, thus improving the installation and disassembly efficiency of the filter screen.
[0004] However, the above-mentioned equipment requires frequent disassembly and cleaning of the filter screen during actual use, because the aquaculture wastewater contains livestock manure and hair and other debris, which are very easy to clog the filter screen, making it difficult to achieve solid-liquid separation, which will seriously restrict the treatment efficiency of aquaculture water.

[0015] Compared with the prior art, this utility model provides an integrated water treatment equipment for livestock farming, which has the following beneficial effects:
[0016] 1. In this invention, sewage flows smoothly through an overflow trough to an inclined filter screen. After preliminary filtration, the water falls into a water tank, while solid impurities flow into a solid-liquid separation tank. A geared motor drives a screw shaft to push the impurities into the filter cylinder. The screw extrudes water from the filter cylinder, and the remaining solids are automatically discharged from the slag outlet through the slag outlet under the cooperation of the sleeve rod, spring, and pressure plate. This process, with the help of screw pushing and spring pressure adjustment, ensures the continuity and high efficiency of solid-liquid separation, effectively separating the solid and liquid components in the sewage.
[0017] 2. This utility model uses a water pump to draw water from the water tank, which is then distributed through a three-way valve. Part of the water enters a serpentine pipe and is sprayed out from the nozzle to backwash the inclined filter screen, preventing it from clogging. The other part enters a branch pipe and is sprayed through the nozzle to wash the filter cartridge. The water separated during the washing and solid-liquid separation process flows back to the water tank through the return pipe, realizing water resource recycling. The liquid sewage in the water tank can be discharged to make liquid fertilizer, which not only ensures the continuous filtration capacity of the equipment, but also improves the water resource utilization rate and the degree of sewage resource utilization.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4 An integrated water treatment device for livestock farming includes a shell 1. Several side blocks 2 are fixedly connected to the inner wall of the shell 1. An inclined filter screen 3 is bolted to the upper surface of the side blocks 2. An overflow groove 4 is opened at the top of the shell 1. A solid-liquid separation tank 5 is opened at the bottom of the shell 1. A spiral shaft 6 is rotatably connected inside the solid-liquid separation tank 5. A geared motor 7 is fixedly connected to one end of the spiral shaft 6. A cylinder support 8 is bolted to the outer wall of the shell 1. A filter cylinder 9 is fixedly connected to the inner side of the cylinder support 8. A sleeve 10 is bolted to the inner side of the cylinder support 8. A cover plate 11 is bolted to one end of the cylinder support 8. A connecting rod 12 is fixedly connected to the end face of the cover plate 11. An end plate 13 is connected to one end of the connecting rod 12 by a nut. A sleeve rod 14 is fixedly connected to one end of the spiral shaft 6. A spring 15 and a pressure plate 16 are sleeved on the outer surface of the sleeve rod 14.
[0025] Specifically, the bottom of the overflow tank 4 is fixedly connected to a sewage inlet pipe 17, and the bottom of the shell 1 is connected to a water tank 18 by a through bolt. A drain valve 19 is connected to the outer wall of the water tank 18.
[0026] The advantage is that by connecting one end of the manure inlet pipe 17 to the livestock manure pipe and pumping the manure into the overflow tank 4 through the slurry pump, the manure rises in the overflow tank 4 and overflows onto the inclined screen 3. This allows the manure to flow to the inclined screen 3 in a relatively stable state, so that the inclined screen 3 can more evenly intercept solid impurities in the manure and let them flow into the solid-liquid separation tank 5 at the bottom of the shell 1. The inclined screen 3 can initially filter out a large amount of water contained in the manure, allowing it to fall into the water tank 18 below after passing through the inclined screen 3.
[0027] Specifically, the base of the geared motor 7 is bolted to the outer wall of the housing 1, and the end of the spiral shaft 6 away from the output shaft of the geared motor 7 is fixedly connected to the sleeve rod 14. The bottom center of the end plate 13 is rotatably connected to the sleeve rod 14 through a bearing.
[0028] Specifically, a slag discharge hole is opened at the center of the bottom surface of the cover plate 11, the end of the slag discharge hole is closely attached to the pressure plate 16, one end of the spring 15 abuts against the pressure plate 16, and the other end of the spring 15 abuts against the end plate 13.
[0029] The advantage is that when solid impurities in the sewage flow into the solid-liquid separation tank 5 at the bottom of the shell 1, the screw shaft 6 is driven to rotate in the solid-liquid separation tank 5 by starting the reduction motor 7. The spiral structure of the screw shaft 6 pushes the solid impurities towards one end of the filter cylinder 9. When the solid impurities enter the filter cylinder 9, the water contained in the solid impurities is extracted from the filter holes of the filter cylinder 9 by the continuous squeezing of the screw shaft 6. This further removes the water from the solid impurities. The solid impurities are continuously pushed to one end of the connecting sleeve 14 of the screw shaft 6. With the cooperation of the sleeve 14, spring 15 and pressure plate 16, as the impurities accumulate, the spring 15 is compressed, and a gap is formed between the pressure plate 16 and the slag outlet hole of the cover plate 11. The solid impurities are discharged through the slag outlet hole, thus completing the solid-liquid separation process. This structure, with the help of the screw pushing and the pressure adjustment of the spring 15, can efficiently separate the solid and liquid components in the sewage, ensuring the continuity and stability of the solid-liquid separation of sewage.
[0030] Specifically, a connecting plate 20 is welded to the inner wall of the shell 1. Several hoops 21 are fixedly connected at equal intervals on the upper surface of the connecting plate 20. A serpentine tube 22 is hooped inside the hoop 21. Several nozzles 23 are fixedly connected at equal intervals on the outer wall of the serpentine tube 22.
[0031] Specifically, one end of the serpentine pipe 22 is fixedly connected to a three-way valve 24, one end of the three-way valve 24 is connected to a water pump 25, and the suction end of the water pump 25 is connected to a suction pipe 26.
[0032] The advantage is that, since the sewage falls into the water tank 18 after being filtered by the inclined screen 3, the water can be drawn from the water tank 18 by starting the water pump 25 and the suction pipe 26, and then enters the three-way valve 24, then the serpentine pipe 22, and finally sprayed out from each nozzle 23. Since the nozzle 23 is aligned with the inclined screen 3, the inclined screen 3 can be backwashed, thus avoiding clogging of the inclined screen 3 and ensuring that the inclined screen 3 always has the ability to filter sewage. It is worth noting that a cover can also be installed on the inclined surface of the housing 1 to seal the inclined screen 3, which can prevent sewage from splashing when backwashing the inclined screen 3.
[0033] Specifically, a water outlet pipe 27 is fixedly connected to the outer wall of the sleeve 10, a return pipe 28 is fixedly connected to the bottom end of the water outlet pipe 27, and the end of the return pipe 28 away from the water outlet pipe 27 is connected to the inside of the water tank 18. Several spray pipes 29 are fixedly connected to the outer surface of the sleeve 10, a branch pipe 30 is fixedly connected to the top end of the spray pipes 29, and a slide plate 31 is welded to the outer wall of the sleeve 10.
[0034] The advantages are that when the water tank 18 is full of water, the water inside can be discharged by opening the drain valve 19. This liquid sewage can be collected in the fermentation tank and made into liquid fertilizer by adding bacteria. When the water pump 25 and the suction pipe 26 draw water from the water tank 18 into the three-way valve 24, the water can also enter the branch pipe 30 by operating the three-way valve 24, and finally flow into each spray pipe 29, so as to wash the filter cartridge 9. In this way, the filter cartridge 9 can be washed after the solid-liquid separation of sewage is completed. The water from the solid-liquid separation process and the water generated from washing the filter cartridge 9 will flow into the return pipe 28 through the outlet pipe 27 and flow back into the water tank 18.
[0035] In use, firstly, connect the manure inlet pipe 17 to the livestock manure pipeline. The manure is then pumped into the overflow tank 4 by a slurry pump. After rising in the overflow tank 4, the manure overflows onto the inclined filter screen 3. After initial filtration, a large amount of water passes through the inclined filter screen 3 and falls into the water tank 18 below, while solid debris flows into the solid-liquid separation tank 5 at the bottom of the housing 1. Subsequently, start the reduction motor 7 to drive the screw shaft 6 to rotate within the solid-liquid separation tank 5. The spiral structure of the screw shaft 6 pushes the solid debris towards one end of the filter cylinder 9. Under the pressure of the screw, water is extracted from the filter holes of the filter cylinder 9, and the solid debris is pushed to one end of the sleeve rod 14. As debris accumulates, the spring 15 is compressed, and the pressure plate... A gap is formed between 16 and the slag outlet of the cover plate 11, through which solid debris is discharged. The water pump 25 is started periodically, and the suction pipe 26 draws water from the water tank 18 into the three-way valve 24. Part of the water enters the serpentine pipe 22 and is sprayed out from the nozzle 23 to backwash the inclined filter screen 3. The other part of the water enters the branch pipe 30 through the three-way valve 24 and then flows into the spray pipe 29 to wash the filter cartridge 9. When the water tank 18 is full of water, the drain valve 19 is opened to discharge the liquid manure into the fermentation tank, where bacteria are added to make liquid fertilizer. The water from the solid-liquid separation process and the water generated from washing the filter cartridge 9 flow into the return pipe 28 through the outlet pipe 27 and return to the water tank 18.
