Description

Technical Field

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

[0002] Sewage treatment is the process of removing pollutants from municipal wastewater, mainly including domestic sewage and some industrial wastewater. Physical, chemical, and biological processes are used to remove pollutants and produce treated wastewater (or treated effluent) that is safe to release into the environment. The by-product of sewage treatment is semi-solid waste or slurry, called sewage sludge. The sludge must be further treated before it is suitable for land treatment or application to land.

[0003] Flocculants are usually used in sewage treatment, which have an efficient sewage treatment effect. Generally, after adding flocculants to sewage, the dirt in the water will gather at the bottom of the container, and the upper layer of the container is the decontaminated water. Usually, the water in the upper layer of the container is pumped out by a water pump with a fixed height. However, as the water level drops, it is difficult for the water pump with a fixed height to draw water, and the effect is poor. Therefore, a flocculation device for sewage treatment is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a flocculation device for sewage treatment to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A flocculation device for sewage treatment, including a bottom plate, on which a control body and a flocculation tank are respectively fixedly connected. One side of the flocculation tank is communicated with a plurality of water suction pipes, and each water suction pipe is provided with a water suction pump. The plurality of water suction pipes are distributed from top to bottom. One side of the flocculation tank is fixedly connected with a connecting block, and the plurality of water suction pumps are all fixedly connected to the connecting block. One end of each of the plurality of water suction pipes is communicated with a water outlet pipe, and a connecting pipe sleeve is arranged at the bottom end of the water suction pipe. The front of the flocculation tank is communicated with a water inlet pipe.

[0006] By arranging the water suction pipes, the plurality of water suction pipes are distributed at different heights on the flocculation tank from top to bottom, so that water can be pumped at different changing water levels. When the water level in the flocculation tank changes, it will be detected by the liquid level gauge in time, and different water suction pumps at different heights will be started accordingly to pump water according to the changes in different water levels, so that the water at different water level heights in the flocculation tank can be flexibly pumped, and the effect is better than that of a fixed water pumping height. In addition, the control body can be used to set and adjust the machine body.

[0007] As a preferred embodiment, a connecting arm is fixedly connected to the back surface of the flocculation tank. A stirring motor is fixedly connected to the lower surface of the connecting arm. An output shaft of the stirring motor is fixedly connected to a stirring rod. A plurality of stirring blades are fixedly connected to the outside of the stirring rod. The stirring rod penetrates and is rotatably connected to the upper surface of the flocculation tank.

[0008] By arranging the stirring motor, the stirring blades on the stirring rod can be driven to rotate under the power output of the stirring motor, so that the flocculant in the flocculation tank can be mixed more fully.

[0009] As a preferred embodiment, a liquid level gauge is arranged on one side of the flocculation tank.

[0010] As a preferred embodiment, a sewage discharge pipe is communicated with one side of the flocculation tank. A sewage discharge water pump is arranged on the sewage discharge pipe. The sewage discharge water pump is fixedly connected to one side of the flocculation tank. An adapter block is fixedly connected to one side of the flocculation tank. A flocculant tank is fixedly connected to the upper surface of the adapter block.

A plurality of lower liquid pipes are communicated with the lower surface of the annular pipe. The bottom ends of the plurality of lower liquid pipes are all communicated with the upper surface of the flocculation tank.

[0013] By arranging the liquid outlet pump, the flocculation liquid in the flocculant tank is pumped through the liquid outlet pipe under the pumping power of the liquid outlet pump and sent into the annular pipe. The annular pipe then injects the liquid into the flocculation tank through the plurality of lower liquid pipes distributed on the flocculation tank. During this period, due to the wide distribution of the injection points of the lower liquid pipes, it helps the liquid to be mixed quickly and saves processing time.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] In the present utility model, by arranging the water suction pipes, a plurality of water suction pipes are distributed at different heights on the flocculation tank from top to bottom, so that water can be pumped at different changing water levels. When the water level in the flocculation tank changes, it will be detected by the liquid level gauge in time, and different water suction pumps at different heights will be started accordingly to pump water, so that the water at different water level heights in the flocculation tank can be flexibly pumped, and the effect is better than that of a fixed water suction height.

[0016] In this utility model, by setting up a liquid outlet pump, under the pumping power of the liquid outlet pump, the flocculant liquid in the flocculant tank is pumped through a liquid outlet pipe and sent into an annular pipe. The annular pipe then injects the liquid into the flocculant tank through a plurality of lower liquid pipes distributed on the flocculant tank.
