[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The present application discloses a sewage discharge system for livestock breeding, referring to Figure 1 , Figure 2 and Figure 3, including a collection box 1 for collecting feces and urine, a plurality of sewage pipes 2 are connected between the collection box 1 and a plurality of toilets, and the collection box 1 is located below the toilets. A partition 3 is welded obliquely on the inner wall of the collection box 1 to separate the collection box 1 into a feces and urine sedimentation area 11 and a urine recovery area 12. A plurality of drainage pipes 31 for connecting the feces and urine sedimentation area 11 and the urine recovery area 12 are vertically welded on the partition 3, and a first filter 32 for filtering and separating feces and urine is detachably connected to the top of the drainage pipe 31. An inspection port 14 is opened on the top of the collection box 1 in the direction of the drainage pipe 31, and a cover plate is installed at the inspection port 14. A urine recovery box 4 is installed on one side of the collection box 1, and a water supply pipe 41 is connected between the bottom of the collection box 1 and the top of the urine recovery box 4, and a first water pump 42 is installed on the water supply pipe 41. A discharge port 13 is provided at the lowest end of the partition 3 on one side of the collecting box 1, and a feces recovery box 5 for collecting feces is connected to the discharge port 13. A baffle 7 for opening / closing the discharge port 13 is rotatably provided in the collecting box 1, and a driving member for driving the baffle 7 to rotate is installed on the collecting box 1.

[0024] In the embodiment of the present application, the feces and urine in the toilet can be discharged to the partition 3 in the collection box 1 through the sewage pipe 2. The feces and urine are accumulated, and the feces can be precipitated to the lower layer, while the urine is located in the upper layer. The upper layer of urine can flow to the urine recovery area 12 below through the drainage pipe 31, and the feces impurities mixed in the urine can be filtered through the first filter 32. The urine in the urine recovery area 12 can be transported to the urine recovery box 4 through the first water pump 42. When the staff feeds the animals in the pen, it can be ensured that no animal uses the toilet. At this time, the baffle 7 can be driven to rotate through the driving member to open the discharge port 13, so that the feces can be discharged to the feces recovery box 5. In addition, the animals can also be driven away by other means so that they do not use the toilet temporarily, ensuring that the feces can be discharged separately into the feces recovery box 5. Through a sewage discharge system for animal husbandry in the present application, animal feces and urine can be separated into solid and liquid so as to process urine and feces. It not only avoids the environmental pollution caused by direct discharge of feces and urine, but also has the effect of improving resource utilization.

[0025] Furthermore, a heating wire 6 for heating feces is installed on the inner wall of the feces recovery box 5, and an exhaust pipe 51 is connected to the top of the feces recovery box 5. A second filter 52 for filtering feces odor is installed on the exhaust pipe 51.

[0026] In the embodiment of the present application, after the feces are discharged into the feces recovery box 5, the baffle 7 rotates to close the discharge port 13, and then the heating wire 6 is started to heat and dry the feces so that the dried feces can be processed into fertilizer. During the heating process, the evaporated gas will produce odor, so the odor can be treated by passing through the second filter 52.

[0027] Reference Figure 4 and Figure 5The first filter 32 includes a first sleeve 321 and a semipermeable membrane 322. The first sleeve 321 is threadedly connected to the top of the drainage tube 31, and the semipermeable membrane 322 is arranged at an end of the first sleeve 321 away from the drainage tube 31; the second filter 52 includes a second sleeve 521 and an adsorbent 522. The second sleeve 521 is threadedly connected to the exhaust pipe 51, and the adsorbent 522 is arranged inside the second sleeve 521.

[0028] In the embodiment of the present application, when urine flows into the drainage tube 31, the semipermeable membrane 322 can block feces outside the drainage tube 31. After the feces are discharged into the feces recovery box 5, the staff opens the cover and can regularly remove and replace the first filter 32. The adsorbent 522 can be activated carbon or other adsorbent materials, so as to play a deodorizing role.

[0029] Furthermore, a plurality of nozzles 9 for flushing the partition 3 and the drainage pipe 31 are installed on the top of the collection box 1, and a water supply tank 91 for supplying cleaning water to the nozzles 9 is installed outside the collection box 1, and the water supply tank 91 has a second water pump built therein.

[0030] In the embodiment of the present application, a plurality of water outlets are provided on the side wall of the nozzle 9 to increase the spray range. By spraying cleaning water through the nozzle 9, the feces on the outer wall of the partition 3 and the drainage tube 31 can be washed to the lowest end of the partition 3. In addition, in the state of long-term use, the feces impurities in the urine are easy to gradually accumulate on the semipermeable membrane 322 and cause blockage, and the nozzle 9 can also wash away part of the feces on the semipermeable membrane 322.

[0031] Specifically, the driving member includes a driving motor 81 and a rotating shaft 82. The rotating shaft 82 is rotatably arranged above the discharge port 13. The baffle 7 is welded and fixed to the outer wall of the rotating shaft 82. The driving motor 81 is installed outside the collection box 1 and is in driving connection with the rotating shaft 82. Starting the driving motor 81 can drive the rotating shaft 82 to rotate, so that the baffle 7 can open / close the discharge port 13.

[0032] Furthermore, the sewage pipe 2 includes two first discharge pipes 21 and one second discharge pipe 22. The multiple toilets are grouped in pairs, and the two first discharge pipes 21 are respectively connected to the bottoms of the two toilets in the same group. The discharge end of the second discharge pipe 22 is connected to the top of the collection box 1, and a Y-shaped three-way pipe fitting 10 is connected between the two first discharge pipes 21 and the corresponding second discharge pipe 22, and connectors are installed at the connection between the Y-shaped three-way pipe fitting 10 and the first discharge pipe 21 and the second discharge pipe 22.

[0033] In this way, the use of pipes can be reduced while ensuring the discharge function of the toilet. In the embodiment of the present application, the pipe is a PE pipe. In addition, when the sewage pipe 2 is blocked, the corresponding Y-shaped three-way pipe fitting 10 can be disassembled and assembled through the connecting piece, so that the staff can dredge the pipe.

[0034] Reference Figure 6 The connecting piece includes a locking ring 20 with a thread on the inner side. Two first discharge pipes 21 and corresponding second discharge pipes 22 of the same group are respectively inserted into the three channels of the Y-type three-way pipe fitting 10. The three channel openings of the Y-type three-way pipe fitting 10 are integrally fixed with an annular sleeve 101 with a conical outer wall. The annular sleeve 101 is composed of two symmetrical arc-shaped pressure plates. The conical surface of the arc-shaped pressure plate is provided with an external thread that matches the internal thread of the locking ring 20. The locking ring 20 is threadedly connected to the annular sleeve 101. Rotating the locking ring 20 can drive the locking ring 20 to move axially along the annular sleeve 101 to adjust the distance between the two arc-shaped pressure plates, thereby squeezing / relaxing the corresponding first discharge pipe 21 and the second discharge pipe 22.

[0035] In order to improve the service life of each pipe fitting, an anti-corrosion layer is fixed inside the first discharge pipe 21, the second discharge pipe 22 and the Y-type three-way pipe fitting 10. The anti-corrosion layer can be made of Teflon or other corrosion-resistant materials, and is made into one piece with the corresponding first discharge pipe 21, the second discharge pipe 22 and the Y-type three-way pipe fitting 10 by co-extrusion technology.

[0036] The implementation principle of a sewage discharge system for animal husbandry in an embodiment of the present application is as follows: the feces and urine in the toilet can be discharged to the partition 3 in the collection box 1 through the sewage pipe 2. The feces and urine are accumulated, and the feces can be precipitated to the lower layer, while the urine is located in the upper layer. The upper layer of urine can flow to the urine recovery area 12 below through the drainage pipe 31, and the feces impurities mixed in the urine can be filtered through the first filter 32. The urine in the urine recovery area 12 can be transported to the urine recovery box 4 through the first water pump 42. When the staff ensures that the animal does not use the toilet, the baffle 7 can be driven to rotate through the driving member to open the discharge port 13, so that the feces can be discharged to the feces recovery box 5. Through the sewage discharge system of the present application, the animal feces and urine can be separated into solid and liquid, so as to process urine and feces. It not only avoids the situation where the direct discharge of feces and urine causes environmental pollution, but also has the effect of improving resource utilization.
