Description

Technical Field

[0001] The utility model relates to the technical field of livestock farm sewage treatment, in particular to a solid-liquid separation device for livestock farm sewage treatment. Background Art

[0002] Livestock farm wastewater treatment is an important part of protecting the ecological environment and achieving sustainable development of the breeding industry. Livestock farm wastewater mainly comes from livestock and poultry excrement, flushing water, and feed residues. Solid-liquid separation devices generally use the filtering effect of the screen to allow solid matter to remain on the screen, while the liquid flows out through the screen. When the sewage flows through the device, the solid feces will be intercepted by the screen, while the sewage continues to flow, thereby achieving solid-liquid separation. The solid-liquid separation device in livestock farm wastewater treatment plays an important role in reducing pollutant concentrations, recycling resources, improving water quality and protecting the environment. During the purchase and use process, it is necessary to clarify needs, understand performance, inspect manufacturers, install and debug, and perform regular maintenance and maintenance.

[0003] The prior art patent document CN214436827U provides a livestock breeding wastewater treatment device. A solid-liquid separation mechanism is provided inside the material separation shell. After the impurities in the sewage are separated from the sewage, the impurities can be quickly discharged and separated through the separation mechanism, which greatly improves the convenience of separating impurities in the sewage, thereby improving the efficiency of sewage treatment. The separation block is made of rubber. When the separation block is located inside the material separation shell and moves, it will ensure that the impurities are efficiently lifted and discharged uniformly from the sewage outlet. A metal sliding plate is provided on the top of the separation block, which will greatly improve the lubrication and efficiency of impurity discharge.

[0004] However, in the existing livestock farm sewage treatment device, the livestock farm wastewater has a high concentration of suspended solids and a high content of organic matter, and may contain a large amount of impurities such as fiber and hair. These characteristics increase the difficulty of solid-liquid separation. The viscosity and fluidity of the wastewater may also affect the effect of solid-liquid separation. If the wastewater has high viscosity, it is easy to adhere to the filter and cause the filter to be blocked; if the wastewater has poor fluidity, it may affect the separation speed. Therefore, we need a livestock farm sewage treatment solid-liquid separation device. Utility Model Content
