Anti-blocking three-grid septic tank capable of promoting efficient fermentation

Abstract

The invention discloses an anti-blocking three-grid septic tank capable of promoting efficient fermentation. The septic tank comprises a septic tank body, the septic tank body comprises a first tank,a second tank and a third tank, an excrement inlet pipe is arranged on one side of the first tank, an exhaust pipe is arranged on the side wall of the upper portion of the first tank, an exhaust assembly is arranged in the middle of the exhaust pipe, the second tank is communicated with the first tank through a first excrement passing pipe, the second tank is communicated with the third tank through a second excrement passing pipe, sewage draining outlets are formed in the upper ends of the first tank, the second tank and the third tank, an openable isolation cover is arranged on each sewage draining outlet, a safety cover is arranged on the isolation cover, a motor is fixedly arranged on the isolation cover of the first tank, and the lower end of an electric telescopic rod is connected with a rotating shaft by a bottom coupling. Lifting rods at the left end and the right end of a swing frame drive lifting plates to vertically move in excrement residues, compacted, caked and hardened excrement residues are broken through a plurality of convex edges on the upper end face, further fermentation of excrement residues at the bottom of a first tank is promoted, the first excrement passing pipe is not prone to being blocked, and the excrement residues are convenient to clean.

Description

technical field [0001] The invention relates to the technical field of septic tanks, in particular to an anti-blocking three-compartment septic tank that can promote high-efficiency fermentation. Background technique [0002] The three-compartment septic tank is to carry out the collection and harmless treatment of feces in the same process. The principle is that the feces enter the first pool from the manure inlet, and the feces in the pool begin to ferment and decompose. Due to the different specific gravity, the feces can be naturally divided into the upper layer. The hydrate and the lower layer of dung, the upper layer of hydrate overflows to the second tank through the dung pipe, and the dung is retained in the first dung tank to continue fermentation, and the dung liquid flowing into the second tank is further fermented and decomposed. To obtain further detoxification, the fecal liquid flowing into the third pool is generally decomposed, and the germs and parasite eggs...

Problems solved by technology

[0003] However, after the existing three-compartment septic tank has been used for a long time, the dung will continue to settle downwards, compacting and agglomerating the dung at the bottom, which will not only affect the continued decomposition of the dung, but also easily cause blockage, resulting in the inability of the hydrate to flow. To the next pool, it also brings difficulties to clear the manure. Therefore, the present invention proposes a kind of anti-blocking three-compartment septic tank that can solve the above problems and can promote high-efficiency fermentation.
