Plastic septic tank

Abstract

The invention discloses a plastic septic tank. The plastic septic tank comprises a septic tank body, wherein the septic tank body comprises an upper tank main body and a lower tank main body; groovesare formed in the inner wall of the upper tank main body and the inner wall of the lower tank main body, and a flange is formed between every two adjacent grooves; male grooves are formed in the flanges of the upper tank main body, female grooves are formed in the flanges of the lower tank main body, and the male grooves and the females are clamped; an upper installing plate and a lower installingplate are welded to the outer wall of the upper tank main body and the outer wall of the lower tank main body respectively. According to the plastic septic tank, by arranging an upper threaded sleeve, a lower threaded sleeve, the female grooves, the male grooves, self tapping screws and sleeve holes, when the septic tank body is assembled, the male grooves in the flanges of the upper tank main body are aligned with the female grooves in the flanges of the lower tank main body, the male grooves are clamped inside the female grooves, one end of the upper threaded sleeve on the upper installingplate is just clamped into the sleeve holes of the lower installing plate in the state that the male grooves and the females are clamped at the same time, the upper threaded sleeve mutually corresponds the lower threaded sleeve at this moment, and a sealing ring is clamped between the upper threaded sleeve and the lower threaded sleeve.

Description

technical field [0001] The invention belongs to the technical field of septic tanks, in particular to plastic septic tanks. Background technique [0002] Septic tank is a device for treating feces and filtering sediment. It uses the principle of sedimentation and anaerobic fermentation to remove suspended organic matter in domestic sewage. The principle is that the solidified matter decomposes at the bottom of the pool, and the hydrated matter in the upper layer enters the pipeline and flows away. , to prevent pipeline blockage, to give solidified objects, that is, waste such as feces, enough time to hydrolyze, and to effectively kill mosquitoes and flies in the working environment of anaerobic corrosion in septic tanks. [0003] However, the traditional plastic three-compartment septic tank adopts the combination of the upper and lower parts. When assembling, the double-sided adhesive tape is pasted and then fixed with screws. In addition, the septic tank needs to be filte...
