Sand setting device for sewage treatment

Abstract

The invention discloses a sand setting device for sewage treatment. The sand setting device comprises a box body, wherein a mounting opening is formed in the center of the outer wall of the top of thebox body; a buffer box is fixed in the mounting opening; a feeding pipe is fixedly inserted into the outer wall of the top of the buffer box; a buffer pipe is fixedly inserted into the center of theouter wall of the bottom of the buffer box; guide openings are formed in the two sides of the bottom end of the circumferential outer wall of the buffer pipe; guiding pipes with opposite discharging port directions fixedly communicate with the two guiding openings; a rotating shaft is rotationally inserted into the bottom of the buffer pipe; the top end of the rotating shaft penetrates through theouter wall of the top of the buffer box to be in transmission connection with a driving mechanism; a turbine mechanism is fixed to the bottom end of the rotating shaft; a drainage mechanism is fixedly inserted into the top end of the outer wall of one side of the box body; and a discharging mechanism is fixedly inserted into the bottom of the box body. According to the sand settling device, an introduced liquid material can be buffered, decelerated and steered, and eddy current generated during sand settling cannot be impacted.

Description

technical field [0001] The invention relates to the technical field of sewage sand settling, in particular to a sand settling device for sewage treatment. Background technique [0002] my country is a country that lacks water resources per capita and is listed as one of the thirteen water-poor countries in the world. With the advancement of industrialization and urbanization in our country, the increasingly serious water pollution not only reduces the use function of water bodies, but further aggravates the contradiction of water shortage, which has a serious impact on China's ongoing sustainable development strategy, and also seriously It threatens the drinking water safety of urban residents and people's health, so the purification of sewage is the need for future development of people. [0003] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse, but in the existing sewage treatment proc...

Problems solved by technology

The existing grit settling devices are generally divided into static grit settling and rotary centrifugal grit settling. The static settling settling takes a long time, and the existing centrifugal settling settling devices have some shortcomings in the process of use, for example, the imported sewage It will cause impact on the eddy current generated during sand settling, making the eddy current turbulent, affecting the effect of centrifugal sand settling, and cannot meet the needs of use
