Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a solid-liquid separation device for wastewater treatment which can prevent clogging. Background Art

[0002] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater in order to purify wastewater, reduce pollution, and achieve the purpose of wastewater recycling and reuse, and fully utilize water resources. Wastewater treatment can be carried out by physical treatment, chemical treatment and biological treatment. Physical treatment separates and removes insoluble suspended pollutants in wastewater through physical action, chemical treatment separates and removes dissolved and colloidal pollutants in wastewater through chemical reactions and mass transfer, or converts them into harmless substances, and biological treatment degrades organic matter, phosphorus, nitrogen and soluble inorganic matter through microorganisms.

[0003] The existing technology for wastewater treatment requires the use of flocculants to flocculate impurities in the sewage and then filter the flocculants. The traditional method is to first stir the flocculant with the sewage and then transfer it to a filtration device for filtration. This method is relatively cumbersome and requires the wastewater to be transferred. Another method is to install a filter screen at the drain port, but the filter screen has a small area and is easily blocked, making it impossible for the wastewater to be discharged.

[0004] Therefore, how to provide a solid-liquid separation device for wastewater treatment that is resistant to clogging to solve the problems existing in the prior art is of great significance for its application. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A blockage-proof solid-liquid separation device for wastewater treatment comprises a stirring kettle, an upper cover is installed at the top of the stirring kettle, a motor is installed at the top of the upper cover, the output shaft of the motor is located inside the stirring kettle, a support leg is installed at the bottom of the stirring kettle, a cylinder is installed on the side of the support leg, the telescopic end of the cylinder extends to the inside of the stirring kettle and is fixedly connected to a filter screen, the middle part of the filter screen is rotatably connected to a rotating tube via a rotating shaft, the rotating tube is sleeved on the outside of the transmission shaft, a rotating seat is installed at the top of the rotating tube, and stirring blades are installed on the side of the rotating seat.

[0008] Preferably, a liquid discharge valve is installed at the bottom end of the stirring kettle, and a material discharge valve is installed on the side of the bottom end of the stirring kettle.

[0009] Preferably, a strip groove is provided on the surface of the transmission shaft, and a protrusion is provided on the inner circle of the rotating seat, and the protrusion is slidably connected to the strip groove.

[0011] Preferably, the filter screen is installed at an angle, and the side of the filter screen close to the discharge valve is lower than the other side thereof.

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

[0013] The utility model filters the flocculants by arranging a liftable filter screen. When in use, waste water and flocculant are put into the stirring kettle, and then the motor is started. The motor drives the transmission shaft to rotate, and the transmission shaft drives the stirring blade to rotate through the rotating seat, so that the flocculant and the waste water are stirred and mixed. After the mixing is completed, the cylinder drives the filter screen to rise, so as to filter the flocculants. The filtered waste water is discharged through the drain valve, and then the cylinder drives the filter screen to descend, and the discharge valve is opened to discharge the flocculants. Compared with the existing reaction kettle, the utility model can lift the flocculants, the filtration is more thorough, the solid-liquid separation is more convenient, and the filter screen is effectively avoided from being blocked.
