Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of livestock and poultry excrement and sewage separation, and more specifically to a livestock and poultry excrement and sewage separation tank. Background Art
[0002] With the continuous development of large-scale farming, a large amount of pig manure and urine is produced during the farming process. Livestock and poultry manure and urine are originally excellent organic fertilizer raw materials, but due to the current improper treatment methods of these manure and urine, not only resources are wasted but also serious environmental pollution is caused.
[0003] In the prior art, the patent application number is CN201920843371.4, and the name is: A feces and urine separation type livestock and poultry manure and sewage separation tank. In the patent, livestock and poultry manure and urine are separated by a filtering structure, and the solid feces on the upper side are cleaned and pushed out by a manure scraper; however, in this scheme, the manure scraper is mainly driven by a pull rope, and it is difficult to ensure that the manure scraper is always in a fit state with the manure trough during movement, and it is difficult to thoroughly clean the manure in the manure trough. The existing patent is a livestock and poultry manure and sewage separation tank, and the patent authorization number is CN219231543U. The filter plate can be used to separate the solid and liquid of the manure, and the scraper is used to scrape the solid feces remaining on the filter plate out from the corresponding discharge port.
[0004] However, in patent authorization number CN219231543U, the first motor is controlled by a controller, and the first screw cooperates with the filter plate to drive the solid feces to move upward and resist the scraper; then the second motor is controlled by the controller to drive the second screw to work, drive the connecting rod to move along the slide rail, and the scraper moves along the upper surface of the filter plate to push the solid feces on the plate. During the process of the scraper scraping the feces on the filter plate, some solids will block the filter holes on the filter plate, so that solid-liquid separation cannot be achieved, thereby affecting the separation effect of feces and sewage. Therefore, we propose a livestock and poultry feces and sewage separation tank to solve the above-mentioned problems. Utility Model Content
