Abstract

The invention discloses a circulating desanding device for sewage treatment, which belongs to the field of sewage treatment. A circulating sand removal device for sewage treatment, comprising a first sand removal chamber and a pressurization chamber, the first sand removal chamber is fixedly connected with the pressurization chamber, the pressurization chamber is rotatably connected with an impeller, and the first sand removal chamber is provided with an inlet Nozzle, the first desander chamber is rotatably connected with the first cam, the first desander chamber is fixedly connected with the first inclined plate, the first sand collection chamber is arranged under the first inclined plate, and the first sand chamber is slidably connected above the first inclined plate. A sieve plate, the first sieve plate is provided with a first filter screen; in the present invention, the setting of the impeller and the first cam facilitates the reciprocating movement of the first sieve plate and the first slide plate, and the reciprocating movement of the first sieve plate facilitates the improvement of the filtering effect. Simultaneously, it is convenient to push the gravel into the first sand collection chamber, the setting of the first sand collection chamber is convenient for collecting the gravel, and the setting of the first air cylinder is convenient for pushing the first sliding plate to slide back and forth to discharge the sewage in the first sand collection chamber.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a circulating desanding device for sewage treatment. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Fields are also increasingly entering the daily life of ordinary people. Sewage is usually mixed with a large amount of gravel. Before sewage treatment, it is generally necessary to settle and separate the gravel in sewage. [0003] Most of the existing sewage desanding devices only filter the gravel through a simple filter screen, the filtration efficiency is low, the effect is not obvious, and it is not convenient to collect the sand and gravel, which will cause the g...
