Description

Technical Field

[0001] The utility model relates to the technical field of sewage sedimentation and filtering devices, in particular to a sewage sedimentation and filtering device. Background Art

[0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent. It includes domestic sewage, industrial wastewater, and other unused water such as initial rain runoff into drainage pipes. With the development of modernization, the population is constantly increasing, and people's water consumption is also increasing. Water use is divided into domestic water and industrial water. The increase in water consumption leads to an increase in sewage, and people's water resources are in a state of tension. Sewage refers to the discharged water from life and production that is polluted to a certain extent. Water that has lost its original use function is simply called sewage. Now industrial and domestic water are discharged at will, which increases the degree of pollution of water resources and damages the ecological environment. Nowadays, when filtering and precipitating sewage, solid-liquid separation cannot be achieved well, causing the pump body to be blocked when extracting the precipitated sewage. At the same time, the precipitated impurities need to be manually removed, which increases the labor intensity of personnel.

[0003] After searching, it was found that a sewage sedimentation and filtration device was disclosed in the Chinese patent with authorization announcement 202321729044.9, including a sewage sedimentation tank and a positioning block, a positioning block is installed at the top right side of the sewage sedimentation tank, and a U-shaped tube body is installed through the positioning block, and a water inlet hole is provided on the left bottom frame of the U-shaped tube body, a connector is installed at the center of the top surface of the positioning block, and an assembly hole is provided at the center of the connector, an operating stud is installed above the center of the connector, and the bottom end of the operating stud is connected to the assembly hole, and a supporting spring body and a connecting sleeve are installed on the outer side of the operating stud. The sewage sedimentation and filtration device can fix the position of the U-shaped tube body by the positioning block, and the left bottom end of the U-shaped tube body is higher than the right bottom end of the U-shaped tube body.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] This sewage sedimentation and filtration device is provided with a U-shaped tube body, and a plurality of water inlet holes are distributed from top to bottom on the lower part of one side of the U-shaped tube body. When draining water, the water inlet holes need to be completely immersed in the liquid surface before the liquid can be discharged. When the liquid level is lower than the water inlet set at the top, the remaining liquid will not be able to be discharged. At the same time, the water inlet holes are not provided with filtering holes, which is easy to cause blockage. Utility Model Content
