Abstract

The invention discloses a circulating desanding device for sewage treatment, and belongs to the field of sewage treatment. The circulating desanding device for sewage treatment comprises a first desanding chamber and a pressurizing chamber; the first desanding chamber is fixedly connected with the pressurizing chamber; an impeller is rotatably connected in the pressurizing chamber; a water inlet is formed in the first desanding chamber; a first cam is rotatably connected in the first desanding chamber; a first inclined plate is fixedly connected in the first desanding chamber; a first sand collecting chamber is arranged below the first inclined plate; a first sieve plate is slidably connected above the first inclined plate; and a first filter screen is arranged in the first sieve plate. According to the invention, by arranging the impeller and the first cam, the first sieve plate and the first sliding plate can reciprocate conveniently; the first sieve plate reciprocates to facilitateimprovement of the filtering effect, meanwhile, gravel is pushed into the first sand collecting chamber conveniently, the gravel is collected conveniently through the first sand collecting chamber, and the first sliding plate is pushed to slide back and forth to discharge sewage in the first sand collecting chamber conveniently through the first air cylinder.

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...
