Sewage disposal mechanism with good anti-blocking effect for sewage disposal

Abstract

The invention belongs to the technical field of sewage treatment, particularly relates to a sewage discharge mechanism with a good anti-blocking effect for sewage treatment, and aims to solve the problem that an existing sewage discharge mechanism often blocks a sewage discharge port due to the fact that the design of the sewage discharge port is not emphasized enough, and provides the following scheme that the sewage discharge mechanism comprises a treatment barrel with an inner cylindrical structure, a drainage pipe of an L-shaped structure is inserted into the circumferential outer wall, close to the bottom end, of the treatment barrel, an opening of the drainage pipe faces upwards, a filter head sleeves the opening in the top end of the drainage pipe, a filter screen is fixed to the top end of the filter head, an annular sliding rail with a C-shaped section and a downward opening is fixed to the circumferential inner wall, close to the bottom end, of the treatment barrel, a T-shaped sliding block is slidably connected into a sliding groove of the annular sliding rail, and a brush plate is fixed to the lower surface of the T-shaped sliding block. Garbage possibly blocked at thepipe opening of the drainage pipe can be cleared away in time, the pipe opening of the blow-off pipe can be tightly blocked along with stirring of water flow, and reverse stirring and blow-off can beconducted.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage discharge mechanism with good anti-blocking effect for sewage treatment. Background technique [0002] At present, domestic and foreign mechanical cleaning of bottom sludge in ponds is mainly to drain the pond water after the breeding is over, and use engineering machinery to remove the sludge at the bottom of the pond. This method cannot remove excess sludge in the pond during the breeding process. Silt and residual bait produced cannot be discharged in time, and the problem cannot be fundamentally solved. [0003] A kind of sewage discharge device for aquaculture ponds disclosed in Chinese patent CN201822024974.X after retrieval, comprises: a fixed column, a clapboard arranged on the top of the fixed column, and a first sewage discharge mechanism and a second sewage discharge mechanism arranged on the inside of the clapboard; the clapboard It is a concentric ...

[0003] A kind of sewage discharge device for aquaculture ponds disclosed in Chinese patent CN201822024974.X after retrieval, comprises: a fixed column, a clapboard arranged on the top of the fixed column, and a first sewage discharge mechanism and a second sewage discharge mechanism arranged on the inside of the clapboard; the clapboard It is a concentric ring structure with the first sewage discharge mechanism and the second sewage discharge mechanism. There are gaps between the partition plate, the first sewage discharge mechanism and the second sewage discharge mechanism. The first sewage discharge mechanism and the second sewage discharge mechanism Several paddles are evenly arranged on the mechanism; however, if a large amount of solid waste appears in the sewage tank when the device discharges sewage, it is easy to block the spiral sewage outlet and it is very difficult to clean
