Embodiment 1

[0026] refer to Figure 1-3 , a sedimentation device for sewage treatment, including a box body 1, a plurality of equidistantly distributed step plates 2 are fixed in the box body 1, and a deflector 6 is fixed below the step plate 2 near the lowest end in the box body 1, and the box body 1 A sliding mechanism is fixed on the inner wall of one side of the body 1 close to the position below the deflector 6, and a buffer mechanism is slidably connected to the sliding mechanism. A water delivery mechanism is fixed on the outer wall of one side of the box body 1, and a hose is fixed on the water inlet end of the water delivery mechanism. 18. The end of the hose 18 away from the water delivery mechanism is fixed with a liquid guiding mechanism.

[0027] The sliding mechanism includes two connecting blocks 12, the same guide rod 9 is fixed on the two connecting blocks 12, two sliders 10 are slidably sleeved on the guide rod 9, and the spring 7 is sleeved on the top of the guide rod 9...

Embodiment 2

[0030] refer to Figure 4 , a sedimentation device for sewage treatment. The difference between this embodiment and Embodiment 1 is that the bottom end of the standpipe 17 is also threaded with a filter mechanism, the filter mechanism includes a collar 22, and a hemispherical filter is fixed at the bottom end of the collar 22. net23.

[0031] The working principle of this embodiment: the collar 22 can lower the overall center of gravity of the standpipe 17, cooperate with the buoyancy ring to make the standpipe 17 more stable in the vertical state, and the hemispherical filter screen 23 can filter the water entering the standpipe 17 Further solid-liquid separation work.

Abstract

The invention discloses a sedimentation device for sewage treatment, which comprises a box body. A plurality of equidistantly distributed step plates are fixed in the box body, a guide plate is fixedbelow the step plate close to the lowest end in the box body, a sliding mechanism is fixed on the inner wall of one side of the box body close to the lower position of the guide plate, and a buffer mechanism is in sliding connection to the sliding mechanism. A water conveying mechanism is fixed to the outer wall of one side of the box body, a hose is fixed to the water inlet end of the water conveying mechanism, and a liquid guiding mechanism is fixed to the end, away from the water conveying mechanism, of the hose. A solid-liquid mixture guided into the box body by the feeding pipe can be buffered, the movement stroke of the solid-liquid mixture is increased, the impact force on impurities precipitated at the bottom of the box body is reduced, the precipitated solid impurities are prevented from being agitated, and the solid-liquid precipitation separation effect is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a sedimentation device for sewage treatment. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] Urban domestic sewage and industrial wastewater are treated by sewage treatment plants and discharged after reaching the standard, which is an indispensable environmental engineering measure for the protection of water resources and the construction of urban ecological environment. Urban sewage treatment plants need to carry out flocculation and sedimentation of sewage...
