Description

Technical Field

[0001] The utility model relates to the technical field of flocculation equipment, in particular to a flocculation equipment used in a sewage treatment plant. Background Art

[0002] The flocculation equipment of the sewage treatment plant is an important part of the sewage treatment process. It is mainly used to remove suspended matter and colloidal substances in the water to make the water clear. Its main function is to cause the suspended particles and colloidal impurities in the water to condense into larger particles for subsequent sedimentation and filtration treatment.

[0003] When the existing flocculation equipment is flocculating sewage, the sewage flows at a relatively slow speed, resulting in incomplete contact between the sewage and the flocculant components, which in turn results in incomplete flocculation of the sewage and requires secondary treatment by the staff, which delays the normal processing progress of the staff.

[0004] Therefore, in view of this problem, the utility model proposes a flocculation device for a sewage treatment plant. Utility Model Content

[0005] The utility model aims to solve the problems in the prior art and proposes a flocculation device for a sewage treatment plant.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a flocculation device for a sewage treatment plant, comprising a treatment box and a fixed fan arranged on the side of the treatment box, a discharge pipe is arranged inside the treatment box, the fixed fan and the discharge pipe are connected by a pipe, a discharge device is arranged at one end of the discharge pipe, a support frame is arranged on the inner wall of the discharge device, a support seat is rotatably provided on the surface of the support frame through a bearing, a rotating blade is arranged on the top of the support seat, and a cleaning blade is arranged on the top of the rotating blade.

[0007] Preferably, a water inlet is provided on the top of the treatment box, a filter screen is provided on the inner wall of the water inlet, the cleaning blade is located above the filter screen, and a water inlet pipe is provided on the side of the water inlet.

[0008] Preferably, a movable cover is hinged on the top of the water inlet, and a handle is provided on the surface of the movable cover.

[0009] Preferably, the side surfaces of the processing box are symmetrically provided with discharge valves, and the discharge valves are located below the fixed fan.

[0010] Preferably, a protective plate is installed on the side of the fixed fan, and a protective net is arranged inside the protective plate.

[0011] Preferably, a discharge nozzle is arranged on the top of the discharge device, a side frame is arranged on the side of the discharge device, and one end of the side frame is arranged on the inner wall of the processing box.

[0012] Compared with the prior art, the utility model provides a flocculation device for a sewage treatment plant, which has the following beneficial effects:

[0013] 1. The flocculation equipment, through the coordinated use of fixed fans, discharge equipment and support base, facilitates the mixing of sewage and avoids the situation that the internal water flow speed is too slow during sewage treatment, resulting in insufficient contact between flocculants and sewage, which requires secondary treatment and increases unnecessary cost expenditure.

[0014] 2. The flocculation equipment is convenient for cleaning and use by setting the coordination between the cleaning blades and the discharge equipment, so as to avoid the blockage of the pipeline by foreign objects when sewage enters, which will affect the normal treatment effect of the staff.
