Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of livestock breeding, and particularly relates to a sewage treatment device for livestock industry. BACKGROUND

[0002] Livestock sewage is complex in composition and contains a large amount of suspended solids, organic matter and pollutants such as nitrogen and phosphorus. If it is directly discharged without effective treatment, it will cause serious pollution to the surrounding soil, water and other ecological environment. The traditional livestock sewage treatment device has the following problems: (1) A fixed flow pump is usually used for adding, which can realize quantitative addition, but cannot be adjusted according to the real-time fluctuation of sewage flow. The sewage discharge of the breeding farm often changes due to factors such as breeding period, feeding time and cleaning frequency. When the sewage flow decreases, the fixed flow addition will cause the relative excess of the medicament, resulting in waste. When the sewage flow increases, the medicament is relatively insufficient, the flocculation effect is weakened, and it is difficult to ensure the stability of the treatment effect. (2) The water purifying agent of the traditional device is directly injected into the sewage, which is easy to form block agglomerates due to poor fluidity and insufficient contact with the sewage. These agglomerates cannot effectively react with the suspended solids in the sewage, the utilization rate of the medicament is low, and the final flocculation effect is affected. SUMMARY

[0003] The application overcomes the shortcomings of the prior art and provides a sewage treatment device for livestock industry. The change of sewage flow is converted into the change of frequency of reciprocating motion of the pressure head, the pulse type addition of the water purifying agent is realized, and the dynamic matching of the sewage flow is realized, so that the concentration peak of each batch of medicament is ensured, and the waste of medicament caused by flow fluctuation is avoided. At the same time, the local turbulence is formed around the impeller by the rotation of the impeller, so that the newly injected water purifying agent is immediately dispersed by the turbulence vortex, the agglomeration state is broken, the immediate and efficient mixing of the medicament and the sewage is realized, and the stability of the flocculation effect is improved.

[0004] The technical scheme adopted by the application is as follows: the present application provides a sewage treatment device for livestock industry, a sewage treatment device for livestock industry, which comprises a barrel body and a water purifying agent storage tank. The water purifying agent storage tank is fixedly arranged on the top wall of the barrel body. A water inlet pipe is fixedly connected to the top wall of the barrel body in a through manner, serving as a channel for sewage to enter the barrel body. The outlet of the water purifying agent storage tank is in through communication with the water inlet pipe through a pipeline. An agent inlet pipe is fixedly arranged on the inner circumferential wall of the water inlet pipe, serving as a transition channel for the water purifying agent to enter the sewage. A pressure head is coaxially and slidably arranged on the inner circumferential wall of the agent inlet pipe. The opening and closing of the water inlet pipe are realized by the up-down reciprocating motion of the pressure head. An installation frame is fixedly arranged on the inner circumferential wall of the water inlet pipe. An impeller is rotatably connected in the installation frame. The impeller is rotated by the impact force of the sewage flowing through, and the kinetic energy of the sewage is converted into mechanical energy. The impeller is in transmission cooperation with the pressure head.

[0005] Further, the impeller top wall is coaxially provided with a transmission rod, and a transmission protrusion is fixedly arranged on the circumferential wall of the transmission rod.

[0006] Further, a spiral driven groove is arranged on the inner circumferential wall of the pressing head, and the transmission protrusion is slidably arranged in the driven groove, so that the circumferential movement of the transmission rod is converted into the linear movement of the pressing head, and the movement trajectory of the up-down reciprocation of the pressing head is guided.

[0007] Further, a cover plate is fixedly arranged on the top wall of the pressing head, and the cover plate is arranged on the upper side of the water inlet pipe.

[0008] Further, a spring is fixedly arranged on the inner wall of the pressing head, and the other end of the spring is fixedly connected with the inner circumferential wall of the medicine inlet pipe.

[0009] The beneficial effects achieved by the above structure are as follows: (1) The circumferential movement of the transmission rod is accurately converted into the linear movement of the pressing head, and the reciprocation frequency of the pressing head is determined by the rotation speed of the impeller, and the rotation speed of the impeller is directly related to the sewage flow, so that the sewage flow and the addition amount of the water purification agent are matched, and the waste caused by the mismatch between the addition amount of the water purification agent and the sewage flow when the sewage flow fluctuates is avoided, and each batch of the water purification agent can form a high concentration peak in the sewage. (2) When the sewage carrying the water purification agent flows through the impeller, the rotation of the impeller forms a local turbulent flow around the periphery, and the strong vortex generated by the turbulent flow can quickly break the agglomeration state of the water purification agent, so that the water purification agent is uniformly distributed in a small range and fully contacts with the sewage, and the flocculation effect is more stable.

[0014] Embodiment one: please refer to Figures 1-5 The embodiment provides a sewage treatment device for animal husbandry, which comprises a barrel 1 and a water purifying agent storage tank 2. The water purifying agent storage tank 2 is fixedly arranged on the top wall of the barrel 1. A water inlet pipe 3 is fixedly and throughly connected to the top wall of the barrel 1. The outlet of the water purifying agent storage tank 2 is in through communication with the water inlet pipe 3 through a pipeline. A one-way valve is arranged in the pipeline to prevent sewage backflow. A medicine inlet pipe 4 is fixedly arranged on the inner circumferential wall of the water inlet pipe 3. A pressure head 5 is coaxially and slidably arranged on the inner circumferential wall of the medicine inlet pipe 4. A driven groove 10 is formed in the inner circumferential wall of the pressure head 5. A cover plate 11 is fixedly arranged on the top wall of the pressure head 5. The cover plate 11 is located on the upper side of the water inlet pipe 3. The diameter of the pressure head 5 is smaller than that of the medicine inlet pipe 4. The diameter of the cover plate 11 is greater than that of the medicine inlet pipe 4. A spring 12 is fixedly arranged on the inner wall of the pressure head 5. The other end of the spring 12 is fixedly connected to the inner circumferential wall of the medicine inlet pipe 4. A mounting frame 6 is fixedly arranged on the inner circumferential wall of the water inlet pipe 3. An impeller 7 is rotatably arranged in the mounting frame 6. A transmission rod 8 is coaxially and fixedly arranged on the top wall of the impeller 7. A transmission protrusion 9 is fixedly arranged on the circumferential wall of the transmission rod 8. The transmission protrusion 9 is slidably embedded in the driven groove 10. In the embodiment, when the sewage flows through the impeller 7 in the inlet pipe 3, the sewage impacts the impeller 7 to generate a thrust force to drive the impeller 7 and the transmission rod 8 to rotate, the transmission protrusion 9 is slidably embedded in the spiral driven groove 10, the circular motion of the transmission rod 8 is converted into the linear motion of the pressure head 5 through the transmission protrusion 9, the pressure head 5 moves up and down along the inner wall of the inlet pipe 4; the transmission protrusion 9 ascends along the spiral of the driven groove 10 to push the pressure head 5 to move upward, at this time, the spring 12 is compressed, and the top cover plate 11 of the pressure head 5 is lifted to separate from the port of the inlet pipe 4 to form a gap; after the cover plate 11 separates from the inlet pipe 4, the water purifying agent in the water purifying agent storage tank 2 flows into the inlet pipe 4 under the action of gravity and is injected into the flowing sewage again; When the transmission protrusion 9 rotates with the transmission rod 8 to the lowest point of the spiral of the driven groove 10, the pressure head 5 moves downward to reset, the cover plate 11 is lowered to re-adhere to the port of the inlet pipe 4 to close the inlet pipe 4 and stop the injection of the water purifying agent; since the transmission rod 8 continues to rotate, the pressure head 5 repeatedly moves up and down at a certain frequency to realize the pulse addition of the water purifying agent, and each batch of the agent can form a concentration peak in the sewage; The sewage carrying the water purifying agent continues to flow along the inlet pipe 3, and when passing through the position of the impeller 7, the rotation of the impeller 7 forms a local turbulent flow at the periphery, and the vortex generated by the turbulent flow rapidly mixes the water purifying agent with the sewage to break the agglomeration state of the water purifying agent, so that the water purifying agent is uniformly distributed in a small range in the sewage to ensure that the agent is uniformly distributed in the sewage and the flocculation effect is more stable; When the injection of the sewage ends, the compressed spring 12 drives the pressure head 5 to move downward, and the cover plate 11 is lowered to re-adhere to the port of the inlet pipe 4 to close the inlet pipe 4 and stop the injection of the water purifying agent, thereby avoiding the waste of the water purifying agent due to the decrease in the sewage flow and the upward movement of the pressure head 5.
