Plastic four-grid septic tank

Abstract

The invention discloses a plastic four-grid septic tank which comprises a cylinder body, a left sealing plate, a right sealing plate, fixing ribs, a first partition plate, a second partition plate, athird partition plate, a water inlet, a cleaning opening, an inspection opening, an exhaust opening and a water outlet, the cylinder body is divided into a first septic tank, a second septic tank, a third septic tank and a fourth septic tank by the first partition plate, the second partition plate and the third partition plate; the first partition plate, the second partition plate, the third partition plate, the left sealing plate and the right sealing plate are connected with the cylinder body through fixing ribs, a circle of thermal fuse wires are arranged on the outer surfaces of the fixingribs, and the fixing ribs are connected with the cylinder body through the thermal fuse wires in a hot melting mode. According to the plastic septic tank, the fixing ribs and the thermal fuses are inhot melting connection with the cylinder body, so that the water isolation capability is high, the sealing performance is improved, meanwhile, the fixing ribs play a role in supporting, the structural strength is improved, and the problems that an existing plastic septic tank with a complex structural form is not qualified in quality, and a spliced part is prone to leakage are solved.

Description

technical field [0001] The invention relates to the technical field of septic tank sewage treatment, in particular to a plastic four-compartment septic tank. Background technique [0002] Most of the current plastic septic tanks have a three-compartment structure. Generally, injection molding parts are used for physical splicing, and the splicing parts are inlaid with sealing strips. This way, the connection parts are prone to leakage, or the rotational molding process is used for one-time molding. The method is restricted by the internal structure and cannot be diversified, which limits its development. For splicing septic tanks, some scholars have proposed to make the seam of the pool body formed by splicing the base and the pool cover close to the top of the pool body, so that the seam is much higher than the center line of the pool body. However, this method still solves the symptoms but not the root cause. The purpose of fundamentally solving the problem. [0003] The...
