Description

A self-cleaning sedimentation tank

technical field

The utility model relates to the field of sewage treatment equipment, in particular to a self-cleaning sedimentation tank.

Background technique

With the development of the times and science and technology, people's living standards are improving day by day, and human beings have higher and higher requirements for the living environment. The pollution of water resources has become one of the most concerned issues of the society. A large amount of sewage discharge has further damaged the water environment. , especially some chemical companies, the sewage is directly discharged into the river without treatment, which seriously damages the environment and affects people's production and life. Therefore, the sewage treatment project is imminent. The steps in the sewage treatment include sewage sedimentation, and sedimentation tanks are often used. However, the cleaning of sedimentation tanks generally requires other equipment for treatment, which is troublesome to operate, and the mud at the bottom is heavy, or long-term. After a period of time, the combination with the bottom of the sedimentation tank is firmer and it is not easy to clean.

Utility model content

In order to solve the above technical problems, the utility model proposes a self-cleaning sedimentation tank, including a grit chamber, the side wall of the grit chamber is provided with an ultraviolet lamp; the bottom of the grit chamber is provided with a sunken sand collecting position , the sand collection position is an inverted truncated circular shape, and a lubricating layer is provided on the inner wall of the sand collection position; a sand mixing device is provided at the bottom of the grit chamber, and the sand mixing device includes a motor, and the output end of the motor is connected to There is a rotating shaft, and a number of agitating nets are arranged on the rotating shaft, and a reflective layer is provided on the surface of the agitating net; a mud outlet pipe is connected to the bottom of the sand collection position, and a sludge pump is connected to the mud outlet pipe.

Preferably, the lubricating layer is polytetrafluoroethylene.

Preferably, the stirring net is triangular.

Preferably, the reflective layer is a mesh structure braided by optical fiber tubes.

Preferably, an isolation net is provided on the upper part of the sand mixing device.

The self-cleaning sedimentation tank proposed by the utility model has the following beneficial effects: the lower part of the sedimentation tank is provided with a grit chamber, and there is a lubricating layer, which will make the mud and sand deposit in the sand collection position, which is convenient for sequential cleaning, reduces the grit settling area, and at the same time , easy to clean. At the same time, the sand mixing device is installed at the bottom of the sand collection position, which continuously stirs to loosen the mud and sand, which is convenient for the mud pump to discharge the mud and sand. This device does not need manual cleaning, saving time and effort.

Among them, 1-grit chamber, 2-ultraviolet lamp, 3-sand collecting position, 4-lubricating layer, 5-motor, 6-rotating shaft, 7-stirring net, 8-reflecting layer, 9-sludge outlet pipe, 10- Sludge pump, 11-separation net.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

In conjunction with Fig. 1, Fig. 2, the utility model proposes a kind of self-cleaning sedimentation tank, comprises grit chamber 1, is provided with ultraviolet lamp 2 on the side wall of described grit chamber 1, and ultraviolet lamp 2 can be on grit chamber 1 Bacteria removal; the bottom of the grit chamber 1 is provided with a sunken sand collection position 3, the sand collection position 3 is an inverted truncated circular shape, the inner wall of the sand collection position 3 is provided with a lubricating layer 4, and the sediment is deposited The sand tank 1 will gradually fall into the sand collection position 3 along the lubricating layer 4, which is easy to clean;

After enough mud and sand have accumulated, it is necessary to remove the mud and sand. A sand mixing device is provided at the bottom of the grit chamber 1, and the sand mixing device includes a motor 5. The output end of the motor 5 is connected to a rotating shaft 6, and the rotating shaft 6 A number of agitating nets 7 are arranged on the top, and the surface of the agitating nets 7 is provided with a reflective layer 8; the bottom of the sand collecting position 3 is also connected with a mud outlet pipe 9, and the mud outlet pipe 9 is connected with a sludge pump 10 for sand mixing. The device rotates to loosen the mud and sand that sinks to the bottom, and then discharges the mud and sand through the silt pump 10, and there is a lubricating layer 4 on the surface, so that the mud and sand will not deposit on the bottom of the pool, it is very convenient to use, and the cleaning effect is good.

Preferably, the lubricating layer 4 is polytetrafluoroethylene, and polytetrafluoroethylene can effectively make the mud and sand go down along the four walls.

Preferably, the stirring net is triangular.

Preferably, the reflective layer 8 is a mesh structure woven with optical fiber tubes, and the reflective layer 8 can reflect the pipeline of the ultraviolet lamp 2 to the mud, sand and water, and remove bacteria in the mud and sand during the stirring process.

Preferably, the upper part of the sand mixing device is provided with an isolation net 11, the isolation net 11 prevents debris from entering the grit chamber 1, and at the same time prevents mud and sand from splashing around during stirring.

Various modifications to the embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
