Detailed ways

Below in conjunction with accompanying drawing and embodiment, further set forth the utility model. As shown in Figure 1, a kind of sewage treatment device comprises treatment tank 1, spray device 3, stirring device 2, centrifugal separation device 4 and water inlet device;

The treatment tank is provided with a funnel 11 at the bottom of the tank, the bottom of the funnel is connected to a sewage pipe 13, and a valve 12 is provided between the funnel and the sewage pipe;

The stirring device is installed on the top of the treatment tank, including a rotating shaft 22 driven by the first motor 21 at the center of the top of the tank body. The rotating shaft includes a main body 221 and a telescopic tube 222 arranged in the main body. The telescopic tube is provided with a telescopic rod 223. Several groups of blades 23 are arranged on the rod, and a rope body 224 connects the top of the telescopic rod with the second motor 225, and drives the telescopic rod to move up and down under the drive of the second motor;

The spraying device comprises spray containers 33 and 34 arranged on the top of the tank body. The spray container communicates with the spray pipe 32 arranged on the inside top of the tank body. The outer wall of the spray pipe is provided with a small hole 321. The liquid in the spray container passes through the third motor 31. Drive the spray into the spray pipe and spray out through the small hole;

The centrifugal separation device is located on one side of the treatment tank, including an inner container 41 and a casing 42, the outer wall of the inner container is a layer of filter cloth 43, the bottom of the casing is connected to the water outlet pipe 45, and the inner container is driven to rotate by the fourth motor 44 at the bottom;

The water inlet device includes a water inlet pipe 52 connected to the treatment tank. The water inlet of the water inlet pipe is provided with a filter cover 51. The fifth motor 5 draws sewage from the water inlet pipe and transports it to the treatment tank.

During work, the fifth motor first pumps the sewage into the treatment tank through the water inlet pipe, and the third motor first drives and sprays the liquid in the spray container 33 into the tank body. The liquid in the spray container 33 is a colorless and odorless chemical substance used to promote flocculation. And the liquid in the spray container 34 then has the chemical substance of disinfection, sterilization, deodorization, and the material that a little promotes flocculation.

The stirring device starts to work at the same time. Driven by the first motor, the blades on the telescopic rod rotate around themselves and stir. Driven by the second motor, the blades move up and down along the telescopic pipe to stir in the tank, so that the sewage in the tank can be mixed Chemicals are stirred thoroughly to mix. After the sewage has undergone sufficient sedimentation and flocculation, the sediment gathers in the funnel at the bottom of the tank. Open the valve, the sediment can be discharged, and close the valve after discharge. This moment, the liquid in the spray container 34 is sprayed into the tank body again, at this stirring flocculation, and precipitation is discharged, and the water in the tank body has become very clean this moment.

Then through the sixth motor 6, the clean water in the tank is pumped into the inner tank of the centrifugal separation device, the inner tank rotates, and the water inside is centrifugally separated. The separated water enters the shell through the filter cloth, and then passes through the bottom of the shell. The outlet pipe is delivered to other water equipment by the seventh motor 7.

The basic principles, main features and advantages of the present utility model have been shown and described above. Those skilled in the industry should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
