[0002] In large-scale dairy farms, due to the large area of ​​the farm, typically several hundred acres, large cowsheds are built, which are then divided into several barns. Each barn usually houses 10-30 cows, who are free-range and can roam freely. Each barn has a feeding trough and a water trough. For example, the utility model patent with patent number CN202322407556.X discloses a yak waterer that allows for timed water replenishment of the water troughs without manual intervention, thus preventing yaks from being unable to drink for extended periods.

[0003] However, when cattle drink water after grazing, leftover feed scraps and straw fall into the water. When multiple cattle drink simultaneously, a large amount of feed scraps and straw residue remains in the water. Furthermore, in northern my country, frequent sandstorms cause open water troughs to accumulate sand, dust, and other impurities. Therefore, it is necessary to change the water in the troughs regularly to maintain clean water quality, prevent turbidity, and reduce the spread of germs. However, when changing the remaining water in the troughs, the water needs to be drained, which can lead to water waste. Additionally, the large number of cattle in the barn, especially during the summer and autumn seasons when mosquitoes are abundant, easily breeds bacteria and pests. Therefore, there is an urgent need for a water circulation system suitable for cattle farms that can improve water efficiency and enhance the hygiene of the barn environment to reduce the threat of bacterial and pest growth.

[0022] Please refer to Figures 1 to 3 A water circulation system suitable for cattle farms, including The drinking water subsystem 100 includes a drinking trough 110, a filter 120, and a return pool 130. The drinking trough 110 is placed inside a cattle shed 400. Several drinking troughs 110 are provided in one cattle shed 400 for cattle to drink water. The drinking trough 110 is either a U-shaped drinking trough 110 or a square drinking trough 110. Each drinking trough 110 is connected to a valve 111 for controlling drainage. The valve 111 is located below the drinking trough 110 and on its drain pipe. When the valve 111 is opened, water in the drinking trough 110 flows out along the drain pipe. Since there is no filter at the bottom of the drinking trough 110, feed scraps and straw residue in the drinking trough 110 are discharged along its drain pipe. The filter 120 is connected to the water trough 110 and is used to collect and settle the water flowing out of the water trough 110. Straw residue and feed debris that have passed through the filter 120 will settle to the bottom of the filter 120, thus achieving the function of filtering straw residue and feed debris. The return pool 130 is connected to the filter 120. After sedimentation, the clarified water in the filter 120 is pumped by a centrifugal pump or discharged by a height difference, and the clarified water in the filter 120 will enter the return pool 130. The return pool 130 is connected to the water trough 110 through a first pump body 131. When water needs to be supplied to a certain water trough 110, the first pump body 131 is turned on to pump water from the return pool 130 to the water trough 110 for the cattle to drink.

[0023] The greywater subsystem 200 includes a greywater tank 210, which is connected to the filter tank 120 and is used to collect the bottom turbid water of the filter tank 120. The bottom turbid water of the filter tank 120 is pumped by a centrifugal pump or discharged by a height difference. The water at the bottom of the filter tank 120 enters the greywater tank 210 and undergoes sedimentation again. At the same time, domestic water, including kitchen water, is also discharged into the greywater tank 210 through a discharge pipe. After sedimentation, the water in the greywater tank 210 is pumped out by a centrifugal pump and diverted to the cattle shed 400 through a water pipe to flush the cattle shed 400, thereby improving the cleanliness of the cattle shed 400 and reducing the threat of bacteria and pests. At the same time, it can also lower the temperature of the cattle shed 400 and keep the cattle in a comfortable environment.

[0024] The wastewater subsystem 300 includes a wastewater treatment tank 310, which is connected to the greywater tank 210. The wastewater treatment tank 310 collects the turbid water from the bottom of the greywater tank 210. Since the bottom of the greywater tank 210 contains a large amount of straw residue and feed scraps, all the turbid water from the bottom of the greywater tank 210 is diverted to the wastewater treatment tank 310. The turbid water includes a mixture of water and straw residue and feed scraps. The wastewater treatment tank 310 is connected to the cattle shed 400. The drain is connected. After the water in the middle water tank 210 washes the floor of the cattle shed 400, generally, after the cattle manure is removed from the floor of the cattle shed 400, it is washed with water again. A small amount of the mixture of cattle manure and water enters the sewage treatment tank 310 through the drain of the cattle shed 400. After sedimentation in the sewage treatment tank 310, the water in the upper layer of the sewage treatment tank 310 is discharged into the orchard or farmland, or the water is discharged; while the lower sediment is dug out periodically and used as organic fertilizer.

[0025] By setting up a drinking water subsystem 100, a greywater subsystem 200, and a sewage subsystem 300 within the farm, the remaining drinking water in the drinking trough 110 of the cattle shed 400 is saved, realizing water circulation for the cattle's drinking water and preventing mosquitoes from laying eggs in the drinking trough 110, thus maintaining water quality. At the same time, the greywater in the greywater pool 210 can clean the floor of the cattle shed 400, improving the cleanliness of the cattle shed 400 and reducing the threat of bacterial growth and pests. Furthermore, the water and lower sediment in the sewage treatment pool 310 that are ultimately returned can be used as organic fertilizer. Thus, the farm achieves water recycling, resulting in water conservation and emission reduction.

[0026] In one possible embodiment, the drinking water subsystem 100 further includes a waste collection filter tank 140, which is connected to the drain pipe of the drinking water trough 110. Water flowing out of several drinking water troughs 110 can simultaneously enter the waste collection filter tank 140. The bottom of the waste collection filter tank 140 has filter holes. Water entering the waste collection filter tank 140 will flow out through the filter holes. The diameter of the filter holes is 0.3-0.5 cm. The filter holes will filter out longer straw and larger feed particles. Straw longer than 1 cm will remain in the waste collection filter tank 140, while smaller straw... Residue and feed scraps flow out from the filter holes. A backwash water gun 141 is installed on the collection filter tank 140, with its outlet extending into the inner cavity of the collection filter tank 140. When a large amount of straw and feed scraps accumulate in the collection filter tank 140, it can cause blockage of the filter holes. Therefore, when water flows into the collection filter tank 140, the backwash water gun 141 is simultaneously turned on. The backwash water gun 141 impacts the filter holes, flushing away the straw and feed scraps near the holes, preventing long straws and large feed scraps from clogging the filter holes due to excessive filtration. Only periodic cleaning of the debris inside the collection filter tank 140 by staff is required. By filtering the remaining water in several of the drinking troughs 110 through the collection filter tank 140 and the filter pool 120, and by backwashing the bottom of the collection filter tank 140 with the backwash water gun 141, the filter holes can be filtered to remove feed scraps and straw residues while preventing them from clogging the filter holes. At the same time, this filtration method is simpler than setting a filter screen 123 on a separate drinking trough 110.

[0027] In one possible embodiment, regardless of whether the water trough 110 is a flat-bottomed or sloping-bottomed water trough 110, after the water is drained, feed residue and straw residue will settle at the bottom of the water trough 110. To keep the bottom of the water trough 110 clean, a flushing component 112 is provided on one side of the water trough 110 for rinsing the water trough 110. After the water is drained, the farmer opens the flushing component 112 to flush the bottom of the water trough 110, flushing the feed residue and straw residue into the drain pipe of the water trough 110. Specifically, the flushing component 112 is a high-pressure water spray device, such as a high-pressure water gun; specifically, the flushing component 112 is a flushing brush, which can achieve both rinsing and brushing functions, keeping the bottom of the water trough 110 clean.

[0028] In a preferred embodiment, the rinsing assembly 112 includes a water storage tank 1121 and a rinsing nozzle 1122. The water storage tank 1121 is installed on the side wall of the drinking trough 110 and can store 3-5L of water. The rinsing nozzle 1122 is connected to the water storage tank 1121. Specifically, a suction pump is installed inside the water storage tank 1121, and the rinsing nozzle 1122 is connected to the suction pump. The rinsing nozzle 1122 draws water from the water storage tank 1121 through the suction pump. The rinsing nozzle 1122 is a conventional water gun nozzle. When the water drawn by the suction pump is sprayed from the rinsing nozzle 1122, it has water pressure, which serves to rinse the bottom of the drinking trough 110 and filter feed residue and straw residue.

[0029] In one possible embodiment, calves are present in the cowshed 400. The calves like to move and jump around in the cowshed 400 and may cross the water trough 110. The cow manure on their hooves will fall into the water trough 110, causing the water trough 110 to become contaminated. Therefore, the water trough 110 is also provided with an anti-crossing fence 113. The anti-crossing fence 113 includes an arched fence 1131 and a crossbar 1132. The arched fence 1131 is set on the water trough 110, and a drinking gap is reserved between two adjacent arched fences 1131. The crossbar 1132 is set on the arched fence 1131 and is used to connect adjacent arched fences 1131. The drinking gaps reserved between the arched railings 1131 allow the cow's head to reach in and drink, while the arched railings 1131 on the water trough 110 can effectively prevent calves from crossing the water trough 110 and prevent cow manure from falling into the water trough 110.

[0030] Preferably, the impurity collection filter tank 140 is further provided with a fixing frame 142 and a collecting pipe 143. The fixing frame 142 is installed above the filter tank 120 and clamps and fixes the impurity collection filter tank 140. One end of the collecting pipe 143 extends into the inner cavity of the impurity collection filter tank 140, and the other end of the collecting pipe 143 is connected to the drain pipe of the drinking water tank 110. The end of the impurity collection filter tank 140 away from the leakage hole is sealed by a cover plate. The collecting pipe 143 and the backwash water gun 141 pass through the cover plate and extend into the inner cavity of the impurity collection filter tank 140.

[0031] In one possible embodiment, the filter pool 120, the reflux pool 130, and the impurity collection filter tank 140 are generally located inside the factory building, which can effectively prevent wind and sand and mosquitoes.

[0032] In one possible embodiment, the impurity collection filter tank 140 is further provided with a fixing frame 142 and a collecting pipe 143. The fixing frame 142 is installed above the filter tank 120 and is fixed to one side of the filter tank 120 by bolts and nuts, and is located above the filter tank 120. The fixing frame 142 clamps and fixes the impurity collection filter tank 140. The fixing frame 142 is provided with a clamp to fix the impurity collection filter tank 140 to the fixing frame 142. One end of the collecting pipe 143 extends into the inner cavity of the collection filter tank 140, and the other end of the collecting pipe 143 is connected to the drain pipe of the drinking trough 110. The collecting pipe 143 is a multi-ended pipe, which is connected to the drain pipes of different drinking troughs 110 in the cattle shed 400. The collecting pipe 143 serves to collect water from different drinking troughs 110, so that feed residue and straw residue in different drinking troughs 110 can be collected into the collection filter tank 140.

[0033] In a preferred embodiment, to prevent some feed debris and straw residue from splashing onto the outside of the collection filter 140 when the backwash water gun 141 backwashes the collection filter 140, the end of the collection filter 140 away from the leak hole is sealed by a cover plate. The collecting pipe 143 and the backwash water gun 141 pass through the cover plate and extend into the inner cavity of the collection filter 140. The upper end of the collection filter 140 is sealed, so even if the backwash water gun 141 backwashes the feed debris and straw residue, the feed debris and straw residue will not splash onto the outside of the collection filter 140.

[0034] In one possible embodiment, the bottom of the filter 120 has an inclined surface. During the sedimentation process of the filter 120 with its inclined surface, most of the impurities will be deposited on the lower side of the inclined surface, which is beneficial for farmers to remove feed scraps and straw residues later.

[0035] In a preferred embodiment, the filter pool 120 has a first gate 121 on its side wall. The first gate 121 is located at or above the waist of the filter pool 120 and is situated near the return pool 130. After sedimentation, the upper layer of water in the filter pool 120 is relatively clear, while the lower layer contains impurities. When the first gate 121 is opened, the clear water from the upper layer is discharged from the filter pool 120. A first guide channel 122 is provided on the outside of the first gate 121, and the clear water discharged from the filter pool 120 flows along the guide channel. The water enters the return pool 130 through the channel; a filter screen 123 is detachably installed in the first guide channel 122; even if the water in the filter pool 120 passes through the impurity collection filter tank 140 to remove impurities and the filter pool 120 to deposit impurities, a small amount of straw powder will still float on the surface of the filter pool 120. Therefore, a filter screen 123 is detachably installed in the first guide channel 122. The filter screen 123 has a small pore size, and the straw powder enters the filter screen 123 with the water flow, which can filter 95% of the straw powder, and then finally falls into the return pool 130 to clarify the water.

[0036] It should be noted that if the collection filter tank 140 is not installed and only the filter screen 123 is installed, large-volume feed scraps and straw residues will clog the filter screen 123, and the filter screen 123 is generally made of plastic wire mesh, which will cause damage to the filter screen 123.

[0037] The filter 120 is also provided with a second gate 124 on its side wall. The second gate 124 is located at or below the waist of the filter 120 and is located on the side close to the sewage treatment tank 310. A second guide channel 125 is provided on the outside of the second gate 124. During use, the first gate 121 is opened first to discharge the clarified water above the filter 120; then the second gate 124 is opened to discharge the impurity-containing water below the filter 120, so that the remaining water in the filter 120 is discharged into the greywater tank 210 through the second guide channel 125. The impurities settled at the bottom of the filter 120 can be removed to the outdoor organic fertilizer accumulation area.

[0038] In a preferred embodiment, a drain pipe 132 is provided in the return pool 130. The drain pipe 132 is connected to the pump body, and the other end of the drain pipe 132 extends to one side of the drinking trough 110. When water needs to be supplied to the corresponding drinking trough 110, the pump body, such as a centrifugal pump, is turned on. The pump body collects water from the return pool 130 and supplies water to the drinking trough 110 through the drain pipe 132.

[0039] In a preferred embodiment, the greywater subsystem 200 further includes a return water network 220 and an outlet water network 230. A portion of the return water network 220 is connected to the greywater tank 210, and another portion of the return water network 220 is connected to the household water outlet and to a rainwater collection trough for collecting household water and rainwater. One end of the outlet water network 230 is connected to the greywater tank 210, and the other end of the outlet water network 230 extends into the cattle shed 400 for flushing the cattle shed 400.

[0040] In a preferred embodiment, the wastewater subsystem 300 further includes a wastewater pipe network 320, which is connected to the wastewater treatment pond 310 and is used to discharge wastewater. The wastewater pipe network 320 includes a wastewater collection pipe and a wastewater discharge pipe. The wastewater collection pipe is used to collect wastewater from the cattle shed 400 or other places, and the wastewater discharge pipe is used to discharge wastewater from the wastewater treatment pond 310. The bottom of the wastewater treatment pond 310 is provided with a sedimentation pit for settling cattle manure, feed scraps, straw residues, etc.
