Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to an integrated sewage treatment device with high efficiency. Background Art

[0002] The sewage from farms is a kind of sewage rich in pathogens (such as Escherichia coli, Ascaris eggs, etc.), and has high contents of organic matter, suspended solids and ammonia nitrogen. After the untreated breeding sewage enters the natural water body, the contents of solid suspended solids, organic matter and microorganisms in the water increase, and then the physical, chemical properties and biological community composition of the water body are changed, making the water quality deteriorate. If not properly treated, it will enter the groundwater layer through surface runoff and infiltration, polluting the groundwater and the surrounding soil. A large number of pathogenic microorganisms contained in the sewage are spread through the water body, endangering the health of humans and livestock. In order to achieve the organic combination of economic benefits, social benefits and environmental benefits, it must be effectively treated.

[0003] Currently, when filtering the waste residue in the sewage from farms, a filter screen is generally used for solid-liquid separation filtration. The mixture waste residue in the fecal sewage is easy to accumulate on the filter screen. If it cannot be automatically and timely removed, it will cause the filter screen to be blocked and not easy to clean, affecting the sewage treatment efficiency. Summary of the Invention

[0004] The present invention provides an integrated sewage treatment device with high efficiency to solve the problems mentioned in the above background art.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] An integrated sewage treatment device with high efficiency includes a treatment tank. A plurality of support legs are fixedly connected to the bottom side of the treatment tank. A liquid inlet is opened at the top of the treatment tank, and the liquid inlet is used for inputting the sewage to be treated. The treatment tank is arranged in a cylindrical shape. A filter screen is fixedly connected inside the treatment tank, and the filter screen is arranged in a conical shape. A fixed cylinder is fixedly connected to the inner top side wall of the treatment tank. A slag discharge pipe is fixedly connected to the top side wall of the fixed cylinder, and the slag discharge pipe penetrates through the side wall of the treatment tank. The slag discharge pipe is arranged in a downward inclination. A spiral rod is rotatably connected inside the fixed cylinder. The bottom of the spiral rod is located at the central lowest end of the filter screen. An electric motor is fixedly connected above the air outlet. The output shaft of the electric motor penetrates through the upper side of the air outlet and is fixedly connected to the upper end of the spiral rod. The bottom end of the spiral rod penetrates through the side wall of the filter screen and is fixedly connected to a rotating pipe. A stirring device is arranged on the side wall of the rotating pipe, and an anti-blowing device is arranged on the rotating pipe.

[0007] Preferably, the stirring device includes four stirring rods, and the four stirring rods are respectively and fixedly connected to the two side walls of the rotating pipe in pairs. One end of each two stirring rods is fixedly connected with a scraping plate, and the two scraping plates are rotationally and slidably connected to the inner side wall of the treatment tank.

[0008] Preferably, the back-blowing device includes a conical cylinder, and the conical cylinder is fixedly connected to the bottom side wall of the treatment tank. The inside of the rotating pipe is hollow, and the bottom end of the rotating pipe penetrates through the bottom side wall of the treatment tank and extends into the conical cylinder. Two connecting rods are fixedly connected to the bottom end of the rotating pipe, and two fan blades are fixedly connected to the bottom ends of the two connecting rods. The fan blades are located inside the conical cylinder. Two symmetrically inclined back-blowing pipes are fixedly connected to the upper end of the rotating pipe. Each back-blowing pipe abuts against the bottom side wall of the filter screen and slides thereon. The inside of each back-blowing pipe is hollow, and each back-blowing pipe is communicated with the rotating pipe. An air outlet in the shape of an elongated strip is formed on the upper side of each back-blowing pipe.

[0009] Preferably, the bottom of the rotating pipe is rotatably connected to the bottom side wall of the treatment tank through a sealing bearing.

[0010] Preferably, a drain pipe is fixedly connected to the bottom side wall of the treatment tank. The drain pipe is communicated with the inner bottom of the treatment tank. A valve is provided on the drain pipe, and a chemical addition pipe is fixedly connected to the side wall of the treatment tank.

[0011] Preferably, the fixed cylinder is a wire cylinder made of stainless steel.

[0012] Preferably, a Teflon coating is provided on the inner side wall of the treatment tank to prevent sticky substances from adhering to the inner side wall of the treatment tank.

[0013] Preferably, an observation window is provided on the side wall of the treatment tank, and the observation window is made of transparent tempered glass.

[0014] Preferably, the treatment steps of the sewage treatment equipment are as follows:

[0015] In the first step, first, the sewage to be treated is put into the air outlet from the liquid inlet. The waste residue in the sewage will be intercepted by the filter screen, and the intercepted waste residue will slide to the central bottom of the filter screen, and the remaining liquid will fall to the inner bottom of the treatment tank;

[0016] In the second step, then, chemicals such as ammonia nitrogen remover and acid-base regulator are added to the treatment tank through the chemical addition pipe. The motor is started, and the motor can drive the screw rod to rotate. The rotation of the screw rod can drive the rotating pipe to rotate. The rotation of the rotating pipe can drive multiple stirring rods to stir the chemicals, so that the chemicals are mixed with the sewage. The rotation of the stirring rods drives the scraping plates to rotate on the inner side wall of the treatment tank, and the scraping plates can scrape off the impurities adhering to the inner side wall of the treatment tank;

[0017] In the third step, the rotation of the screw rod can gradually lift the waste residue at the central bottom of the filter screen along the fixed cylinder until the waste residue reaches the top of the slag discharge pipe, and then the waste residue automatically discharges and is collected along the slag discharge pipe. While the rotating pipe rotates, the rotating pipe can drive the fan blades to rotate through the connecting rod, so that the fan blades compress the external air and enter it into the rotating pipe. Then, the compressed air flow enters into the two backwashing pipes along the rotating pipe and finally blows out from the air outlets on the backwashing pipes. The blowing air flow can blow out the impurities blocking the mesh holes inside the filter screen, avoiding the blockage of the filter screen.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] The present invention is reasonably designed and integrally arranged. It automatically discharges the waste residue that is likely to accumulate on the filter screen through the screw, avoiding the problems of filter screen blockage and difficult cleaning. At the same time, it can also perform bottom backwashing on the filter screen to blow out the impurities blocking the mesh holes inside the filter screen, avoiding the blockage of the filter screen and greatly improving the sewage treatment efficiency.
