[0002] The pig farming industry is an important part of agriculture, and pork is an important food for urban and rural residents. The development of the pig industry is of great significance to ensuring market supply, increasing farmers' income, and promoting stable economic and social development. The new technology of welfare pig farming is an assembly technology of scientific design of pig houses, reasonable temperature control, and effective pollution control. It can effectively solve the three major problems of large temperature difference, heavy pollution, and strong odor in the process of large-scale pig farming, improve the pig farming environment and public health conditions, and promote the transformation of healthy farming methods and the construction of new countryside. Sewage treatment is an important part of the welfare pig farming system. The sewage generated in the pig farming process includes various feces, feed, sundries, etc. When treating sewage, it is often necessary to first separate the sewage into solids and liquids, separate the solid materials for composting and regeneration, and reprocess the separated sewage until it meets the standards for discharge or reuse. The sewage treatment devices used in the solid-liquid separation step in the existing technology often lack closure and automation, and the treatment efficiency is also low. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the invention provides a welfare pig farming sewage treatment system device, which solves the problems of the prior art welfare pig farming sewage treatment system device lacking in closure and automation and having low efficiency.

[0004] According to an embodiment of the invention, a welfare pig farm sewage treatment system device comprises a fixed outer cylinder, an inner cylinder is arranged inside the outer cylinder, a treatment box is arranged at the bottom, the inner cylinder is provided with a water inlet structure, and the outer cylinder is provided with a drainage structure;

[0005] The inner cylinder comprises, from top to bottom, a filter cylinder, a conical ring, and a sedimentation cylinder with a diameter smaller than that of the filter cylinder, and filter holes are provided on the side walls of the filter cylinder and the sedimentation cylinder; the end with the larger opening of the conical ring is fixedly connected to the filter cylinder, and the smaller end is fixedly connected to the sedimentation cylinder; a rotatable hollow rod is installed in the center of the filter cylinder, a scraping plate is fixedly connected to the outside of the hollow rod, and a lifting rod is installed inside the interior, and one end of the lifting rod extending out of the hollow rod is fixedly connected to a conical extrusion block, the smaller end of the extrusion block is fixedly connected to the hollow rod, and the larger end is consistent with the diameter of the sedimentation cylinder, the side edge of the scraping plate contacts the filter cylinder, and the bottom edge contacts the side wall of the extrusion block when it rises;

[0006] A lifting blocking block is installed below the processing box.

[0008] In this embodiment, when sewage is treated, the sewage to be treated is transported to the inner cylinder through the water inlet structure; the lifting rod is first driven up by the second driving mechanism to ensure that the extrusion block on the lifting rod exits the sedimentation cylinder and maintains a state of conflict with the scraper. Since the maximum diameter of the extrusion block is consistent with that of the sedimentation cylinder, and the diameter of the sedimentation cylinder is smaller than the diameter of the filter cylinder, the extrusion block maintained in the rising state will not block the communication between the sedimentation cylinder and the filter cylinder, and allows the blocking block to extend into the sedimentation cylinder; the sewage entering the inner cylinder is filtered through the filter holes on the filter cylinder and the sedimentation cylinder, and finally passes through the drainage on the outer cylinder. The filter cylinder is then filtered and the filter is then filtered, and the filter cylinder is then filtered and the filter is then filtered, and the filter cylinder is then filtered and the filter cylinder is then filtered.

The dynamic mechanism drives the pushing member to move horizontally, and the pushing member pushes the squeezed solid material on the blocking block and pushes it out from the opening on the processing box to facilitate subsequent processing, thereby completing the solid-liquid separation of the sewage; after the blocking block rises to the sedimentation cylinder, filtration can continue; this solution has a high degree of automation, can automatically separate the sewage, automatically compress the filtered solid material, and can automatically collect the separated solid material, with high overall filtration efficiency and good filtration effect; and when this solution is running, the sewage is always kept in the outer cylinder, with good airtightness, avoiding direct contact between the sewage and the outside and affecting the working environment.
