Radial flow sedimentation tank structure combining vertical screw extrusion dewatering

Abstract

The invention discloses a radial flow sedimentation tank structure combining vertical screw extrusion dewatering. The radial flow sedimentation tank structure comprises a tank body, a top plate is fixedly arranged at the top of the tank body, an overflow groove is formed in the middle of the top plate, a water outlet is formed in one side of the upper portion of the tank body, a water inlet is formed in one side of the middle of the tank body, a dewatering outlet is formed in one side of the lower end of the tank body, the other end of the dewatering outlet is communicated with a dewatering water receiving device, and a driving motor is fixedly mounted at the center of the upper end of the top plate through screws. A dewatering screw rod is additionally arranged, sludge deposited at the bottom of the tank body can be dewatered, water resource loss is reduced, resources are saved, stirring sedimentation and sludge extrusion dewatering can be freely switched by the aid of a clutch, operation is simpler and more convenient, a sludge conveying mechanism comprising a mud retaining plate, a rotary splash guard and a rotating rod can automatically convey sludge to the bottom of the tank body under cooperation of the driving motor and the clutch, the structure is convenient to use, manpower is saved, and use requirements can be effectively met.

Description

technical field [0001] The invention relates to the field of environmental protection, and in particular provides a radial flow sedimentation tank structure combined with vertical screw extrusion dehydration. Background technique [0002] With the rapid development of the economy, the pressure of water shortage is increasing. People gradually realize the importance of water resources and rational use. Sewage treatment has become an inevitable choice for social sustainable development. In order to make sewage reach a certain level of drainage Water or reuse requirements, more and more fields such as: construction, transportation, energy and other industries gradually develop sewage treatment technology, from ordinary physical precipitation to mechanical extrusion and even chemical precipitation dehydration, many industries pay more and more attention to sewage treatment. [0003] The current radial flow sedimentation tank does not have the function of squeezing and dehydratin...

AI Technical Summary

Problems solved by technology

[0003] The current radial flow sedimentation tank does not have the function of squeezing and dehydrating the sludge at the bottom of the tank, and the sludge is directly discharged, which will lead to the loss of water resources, violate the concept of sustainable development, and cannot meet the requirements of use.
