Abstract
Description
Technical Field
[0001] This utility model relates to the field of manure separation technology, and in particular to a manure separation and drainage device for chicken coop farming. Background Technology
[0002] Against the backdrop of the booming global agricultural industry, poultry farming, as a crucial link in it, is experiencing unprecedented large-scale expansion. With the continuous increase in demand for eggs and poultry meat, the density of chicken farming in coops is increasing daily, undoubtedly posing a severe challenge to the maintenance of the farming environment. Statistics show that a medium-sized modern chicken coop can house tens of thousands of chickens. Such a large flock generates tons of manure and wastewater daily. If this untreated waste is discharged indiscriminately, it will not only lead to soil fertility imbalance and severe water pollution, causing mass deaths of aquatic life, but also pollute the air with foul odors, affecting the quality of life of nearby residents and triggering numerous environmental problems and social conflicts.
[0003] Most existing manure separation and drainage systems for chicken farming operate based on simple physical filtration and gravity sedimentation principles. Typically, a slope is set up on the chicken coop floor to guide the wastewater to the drain outlet. During the flow, the wastewater first passes through a coarse screen to intercept larger debris such as twigs and feathers. It then enters a sedimentation tank, where gravity causes the manure particles to slowly settle to the bottom, while the relatively clear water on top is discharged through overflow.
[0004] In existing technologies, some devices use a high-speed rotating drum to throw water against the outer wall using strong centrifugal force, but only surface water can be thrown out. Therefore, a manure separation and drainage device for chicken coops is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a manure separation and drainage device for chicken coop farming, which aims to improve the problem of insufficient separation in some existing devices.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a manure separation and drainage device for chicken coop farming, comprising a shell, a separation mechanism provided on the outside of the shell, a support frame fixedly connected to the bottom of the shell, a buffer chamber rotatably connected inside the separation mechanism, a self-cleaning mechanism provided outside the buffer chamber, the separation mechanism comprising a support block, the support block being fixedly connected to the outside of the shell, a braking assembly being fixedly connected to the outside of the support block, the braking assembly comprising a motor, the motor being fixedly connected to the outside of the support block, a rotating shaft being fixedly connected to the drive end of the motor, a feed pipe being fixedly connected inside the shell, a filter screen cylinder being rotatably connected to the outside of the rotating shaft, and a feed hole being provided on the outside of the rotating shaft;
[0007] As a further description of the above technical solution: the self-cleaning mechanism includes a cylinder, the cylinder is fixedly connected to the outside of the buffer chamber, the driving end of the cylinder is fixedly connected to a pushing cleaning ring, and the pushing cleaning ring is slidably connected to the outside of the filter screen cylinder;
[0008] As a further description of the above technical solution: a spiral guide plate is provided inside the filter screen cylinder, a push threaded rod is fixedly connected to one end of the filter screen cylinder, a filter screen is rotatably connected to the outside of the push threaded rod, and the filter screen is fixedly connected to the inside of the outer shell.
[0009] As a further description of the above technical solution: the other end of the push threaded rod is fixedly connected to a connecting frame, and the outside of the connecting frame is fixedly connected to the outside of the housing;
[0010] As a further description of the above technical solution: the other end of the filter screen is rotatably connected to the outside of the filter screen cylinder;
[0011] As a further description of the above technical solution: the top of the support frame is fixedly connected to the bottom of the buffer chamber, and the top of the buffer chamber is fixedly connected to the bottom of the motor;
[0012] As a further description of the above technical solution: the bottom of the outer shell is fixedly connected to the top of the support frame;
[0013] As a further description of the above technical solution: the top of the outer shell is fixedly connected to a feed inlet, and the bottom of the outer shell is fixedly connected to a discharge outlet.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the support block provides stable support for the motor, ensuring that the rotating shaft rotates smoothly. This ensures that the combination design of the filter screen cylinder and the spiral guide plate can continuously and efficiently push the mixture of feces and sewage forward during rotation. By utilizing the dual effects of centrifugal force and physical filtration, the liquid is made to flow out quickly through the screen holes, achieving preliminary solid-liquid separation, improving the separation speed, reducing the residence time of the mixture in the device, and reducing the risk of clogging.
[0016] 2. In this utility model, when there is a risk of clogging in the filter screen cylinder, the cleaning ring pushed by the cylinder can quickly scrape off the attached impurities. This not only saves a lot of labor and time costs, but also maintains the filtration performance of the screen cylinder in real time, ensuring that the device is always in a high-efficiency working state. This function is especially suitable for chicken houses with large-scale breeding and large amounts of manure and sewage, avoiding a sharp drop in separation efficiency due to clogging of the screen holes and maintaining a good sanitary environment in the chicken house.

The motor 4 is fixedly connected to the outside of the support block 3. A rotating shaft 11 is fixedly connected to the drive end of the motor 4. The motor 4 is used to drive the rotating shaft 11 to rotate. A feed pipe 14 is fixedly connected inside the outer shell 1. A filter screen 8 is rotatably connected to the outside of the rotating shaft 11. The filter screen 8 is made of fine and durable stainless steel mesh, which effectively filters liquids and blocks solid feces, achieving preliminary separation. A feed hole 12 is opened on the outside of the rotating shaft 11.
[0026] The filter screen cylinder 8 has a spiral guide plate inside. One end of the filter screen cylinder 8 is fixedly connected to a push threaded rod 9, which is used to push solid feces to be squeezed and separated again inside the filter screen 16. The filter screen 16 is rotatably connected to the outside of the push threaded rod 9. During operation, the filter screen 16 assists the push threaded rod 9 in filtration. The outside of the filter screen 16 is fixedly connected to the inside of the outer shell 1. The other end of the push threaded rod 9 is fixedly connected to a connecting frame 6, which is an auxiliary support component. The outside of the connecting frame 6 is fixedly connected to the outside of the outer shell 1. The other end of the filter screen 16 is rotatably connected to the outside of the filter screen cylinder 8. The top of the support frame 5 is fixedly connected to the bottom of the buffer chamber 13. The top of the buffer chamber 13 is fixedly connected to the bottom of the motor 4. The buffer chamber 13 is used to rotate while feeding.
[0027] Reference Figure 1 , Figure 2 and Figure 4 The self-cleaning mechanism includes a cylinder 15, which is fixedly connected to the outside of the buffer chamber 13. A push cleaning ring 10 is fixedly connected to the drive end of the cylinder 15. The cylinder 15 is used to push the push cleaning ring 10. The push cleaning ring 10 is slidably connected to the outside of the filter screen cylinder 8. The bottom of the outer shell 1 is fixedly connected to the top of the support frame 5.

The bottom of the outer shell 1 is fixedly connected to the discharge outlet 7, which is used to discharge the separated sewage.
[0028] Working principle: The mixture of manure and wastewater in the chicken coop enters the device through inlet 2. The mixture flows along inlet pipe 14, enters buffer chamber 13, and then enters filter screen cylinder 8 through inlet hole 12 on rotating shaft 11. It then passes through holes on the outside of filter screen cylinder 8 into rotating shaft 11. Motor 4, supported by support block 3, drives rotating shaft 11, which in turn rotates filter screen cylinder 8. Because a spiral guide plate is installed inside filter screen cylinder 8, it pushes the manure and wastewater mixture forward within the filter screen cylinder 8. During this process, the liquid portion passes through... The solid waste is filtered through the screen holes of the filter screen cylinder 8 and flows into the interior of the outer shell 1. After preliminary filtration, the remaining solid waste continues to move towards the push screw rod 9 driven by the motor 4 as the filter screen cylinder 8 rotates. The push screw rod 9 filters again through the filter screen cylinder 8, further pushing the solid waste towards the filter screen 16 to achieve further solid-liquid separation. After sufficient separation, the separated waste is discharged through the discharge port 7 and can be used for subsequent composting and other treatments. The separated solid waste is discharged through the opening of the connecting frame 6 and can be discharged through a suitable drainage pipe for subsequent sewage treatment.
[0029] When it is necessary to clean the filter screen cylinder 8, the cylinder 15 pushes the cleaning ring 10 to slide on the outside of the filter screen cylinder 8. Pushing the cleaning ring 10 will scrape off the solid impurities attached to the screen holes of the filter screen cylinder 8, prevent the screen holes from being blocked, and ensure the separation efficiency of the device.
