[0002] Domestic sewage is wastewater generated in daily life, such as for washing clothes, cooking, and flushing toilets. It is generally treated using the AO process before being discharged into the municipal pipe network. Then, sewage treatment plants centrally process the sewage, using sewage treatment equipment to filter out the wastewater generated in daily life, and finally obtain clean water that can be reused. For example, the water can be used to water trees and flush toilets, so that water can be recycled.

[0003] Existing laminar flow sedimentation equipment for domestic sewage treatment cannot spray chemicals on the sewage before sedimentation to facilitate rapid sedimentation, thus reducing work efficiency. Therefore, a new type of laminar flow sedimentation equipment for domestic sewage treatment has emerged. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laminar flow sedimentation device for domestic sewage treatment. This device solves the problem mentioned in the background art that the sewage cannot be sprayed with chemicals before sedimentation to facilitate rapid sedimentation, thus reducing work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laminar flow sedimentation device for treating domestic sewage, comprising a sedimentation tank, a chute fixedly connected to one side of the sedimentation tank, a sliding plate slidably connected inside the chute, a hollow trough fixedly connected to the top of the chute, a liquid outlet fixedly connected to one side of the sliding plate, a U-shaped plate fixedly connected to the top of the sedimentation tank, a moving motor fixedly connected to one side of the U-shaped plate, a threaded rod rotatably connected inside the U-shaped plate, a chemical storage tank fixedly connected to one side of the sedimentation tank, a water pump fixedly connected to the top of the chemical storage tank, a telescopic pipe provided in the inner cavity of the hollow trough, and a suction pump fixedly connected to one side of the chemical storage tank.

The suction pump delivers water to the storage tank through the pipeline to dilute the medicine solution. Under the action of the outlet pump, the outlet pump delivers the diluted medicine solution through the pipeline to the telescopic pipe. The telescopic pipe delivers the medicine solution to the sliding plate. Finally, the medicine solution is sprayed from the outlet head into the sewage from the sedimentation of the western medicine. The operation of the moving motor is controlled. With the assistance of the U-shaped plate, the moving motor drives the threaded rod to rotate. The threaded rod drives the sliding plate to move inside the trough. The sliding plate drives the outlet head to move.

It has the function of spraying medicine in different areas.

[0007] Furthermore, a stirring motor is fixedly connected to one side of the sedimentation tank, a rotating shaft is fixedly connected to the output end of the stirring motor, a roller and a limiting wheel are fixedly connected to the outer surface of the rotating shaft, a stirring rod is fixedly connected to the outer surface of the roller, and a belt is driven to the outer surface of the limiting wheel.

The mesh plate supports the top quartz sand, activated carbon, and filter cotton layers. The filtered wastewater is discharged from the outlet, resulting in clean water. When it is necessary to remove the sedimented impurities, a water pipe is connected to the outlet, and the baffle is manually pulled up. Using the reverse impact of the water, the water passes through the mesh plate, quartz sand, activated carbon, and filter cotton layers, carrying the impurities out through the drain outlet, thus filtering out the impurities.

Under the action of the outlet pump, the outlet pump delivers the diluted medicine solution through the pipeline to the telescopic pipe. The telescopic pipe delivers the medicine solution to the sliding plate. Finally, the medicine solution is sprayed from the outlet head into the wastewater where the western medicine has settled, thus having the function of transporting the medicine solution.

[0016] By adopting the above technical solution, when it is necessary to remove the precipitated impurities, the water pipe is connected to the water outlet, the baffle is manually pulled up, and the reverse impact of the water is used. The water passes through the grid plate, the quartz sand filter layer, the activated carbon filter layer and the filter cotton filter layer.
