Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a centralized collection and treatment device for wastewater from livestock farms. Background Technology

[0002] With the increasing emphasis on healthy living in recent years, the aquaculture industry has developed rapidly, resulting in a large number of farms. However, the wastewater from these farms mainly consists of high-concentration organic wastewater rich in pathogens (such as E. coli and roundworm eggs), suspended solids, and ammonia nitrogen. If not properly treated, this wastewater will enter the groundwater layer through surface runoff and infiltration, polluting the groundwater. This will increase the content of suspended solids, organic matter, and microorganisms in natural water bodies, altering the physical, chemical, and biological community composition of the water and deteriorating the water quality. Furthermore, the large number of pathogens contained in the wastewater can spread through the body, endangering the health of humans and animals. In addition, the wastewater from farms usually contains animal feces, and direct discharge of these feces not only pollutes the environment but also wastes resources.

[0003] The existing patent with patent number CN 208218580 U discloses a wastewater treatment device for aquaculture farms. It can purify wastewater from aquaculture farms, avoid environmental pollution, and also enable resource reuse. However, the wastewater flows into the sedimentation tank for sedimentation, which may cause blockage, clog the filter screen, prevent water from passing through, and increase the water content of the filtered sludge, causing trouble for subsequent treatment. Moreover, the sludge filtered on the filter disc is inconvenient to handle and may cause blockage.

[0004] In view of this, we will study and improve the existing problems and provide a centralized collection and treatment device for sewage from livestock farms. The aim is to solve the problems and improve the practical value of the technology. Utility Model Content

[0008] As a further optimization of this technical solution, the filter barrel of the centralized collection and treatment device for sewage in livestock farms of this utility model is a cylindrical shell structure with one end open, and multiple round holes are opened on the outer circumference of the filter barrel, and the filter barrel is installed at an angle.

[0009] As a further optimization of this technical solution, the outer cylinder of the centralized collection and treatment device for livestock farm sewage of this utility model is a cylindrical shell structure, and the two ends of the outer cylinder are provided with round holes for installing filter barrels.

[0010] As a further optimization of this technical solution, the filter barrel and the mudguard of the centralized collection and treatment device for livestock farm sewage of this utility model are provided with round holes for installing bearings at their relative positions, and the two ends of the spiral blade are connected to the inner wall of the filter barrel and the mudguard through the bearings to form a rotating device.

[0011] As a further optimization of this technical solution, the pitch of the spiral blades in the centralized collection and treatment device for sewage from livestock farms gradually decreases from the end furthest from the mudguard to the end closest to the mudguard.

The two ends of the spiral blade are connected to the inner walls of the filter bucket and the mudguard via these bearings, forming a rotating mechanism. The spiral blade rotates from a point away from the mudguard. The screw pitch gradually decreases towards the end near the mudguard. A motor controls the rotation of the spiral blades, scraping sludge from the filter bucket to the mudguard and extruding it. The squeezing force increases closer to the mudguard, reducing the moisture content of the extruded sludge. A connecting plate, inserted into the inner wall of the sludge outlet, is a sliding device. A cylinder controls the mudguard to move the scraper, which scrapes the sludge filtered from the filter plate into the sludge storage bucket. This improved wastewater collection and treatment device for livestock farms features a reasonable structural design, low sludge moisture content during separation, and prevents clogging, effectively solving the problems and shortcomings of existing technologies and equipment.
