Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment device. Background Art

[0002] In sewage treatment, flocculants are usually required to flocculate the sewage. Existing flocculation devices usually include a tank, a motor and a filter. Sewage and flocculants are put into the tank and stirred and mixed by a motor to form a large number of flocs. The flocs are filtered out through the filter and the sewage is discharged for the next step of treatment. However, sometimes due to too many flocs, the filter needs to be cleaned frequently to avoid clogging, affecting work efficiency. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. A sewage treatment device exemplified by the utility model, when in use, injects sewage into the tank through the water inlet, sprays a flocculant solution into the sewage through the feed inlet, starts the motor, and the motor rotates to drive the rotating shaft and the stirring rod to rotate to stir the sewage in the tank, so that the floating objects in the sewage are flocculated into flocs. At the same time, under the action of centrifugal force, the flocs rotate and move along the inner wall of the cylinder. At the same time, the rotating shaft rotates through the first gear, the second gear and the inner gear ring to drive the cylinder to rotate, and the rotation direction of the cylinder is opposite to that of the filter screen. During the rotation process, the filter screen can capture the flocs, and when the cylinder rotates until the first opening is connected with the second opening. Under the action of water pressure, the flocs are flushed out of the second opening. At the same time, the water flow can backwash the filter until the first opening is misaligned with the second opening. The movement of the filter can capture the flocs again, thereby cleaning the flocs in the sewage. Subsequently, the sewage is discharged through the water outlet and enters the subsequent filter unit for secondary filtration. Since the amount of flocs in the sewage is small at this time, the number of cleaning times of the filter unit can be reduced, and the work efficiency can be improved. Through this device, the flocs can be conveniently captured and cleaned during the flocculation process, which can reduce the pressure of the subsequent filtration process, reduce the number and frequency of subsequent cleaning, and is more convenient to use.

[0014] 2. A sewage treatment device according to an example of the utility model can store the discharged flocs through the outer shell, and can conveniently clear the flocs in the outer shell through the discharge valve.

[0015] 3. A sewage treatment device exemplified in the present invention can conveniently introduce sewage into a tank body through an inlet pipe, can conveniently inject a flocculant solution into the tank body through a feed pipe, and can conveniently discharge the treated sewage to a subsequent filtration unit through an outlet pipe.

[0016] 4. A sewage treatment device in the example of the utility model can conveniently control the water flow rate through a flow control valve to avoid excessive drop in the water level in the tank.

[0017] 5. A sewage treatment device exemplified in the utility model can disperse the flocculant solution into the sewage below through a liquid disperser when the flocculant solution is injected into the tank body, so as to facilitate better mixing with the sewage.

[0018] 6. A sewage treatment device exemplified in the utility model can limit the position of the lower end of the rotating shaft through a support ring and a support rod to prevent the lower end of the rotating shaft from vibrating during rotation.

[0019] 7. A sewage treatment device in the example of the utility model can conveniently support and elevate the tank body through supporting legs. BRIEF DESCRIPTION OF THE DRAWINGS
