An environmental protection ditch debris blocking device

Abstract

The invention discloses a sundry blocking device of an environment protection ditch, and relates to the field of ditch environment protection. The device comprises a ditch body, a first filtering screen is arranged in the ditch body, and a second filtering screen is arranged on the right side of the first filtering screen; the first filtering screen and the second filtering screen are V-shaped, agap is formed between the bottom of the first filtering screen and the bottom wall of the ditch body, and grids of the first filtering screen are greater than those of the second filtering screen; twofirst baffle plates are fixedly arranged on the left side of the first filtering screen and symmetrically arranged in the ditch body, first sundry collecting pieces are arranged on the first baffle plates, and a sewage stirring device is arranged between the first filtering screen and the second filtering screen; a sediment gathering block is arranged on the right side of the second filtering screen, and a sediment depositing groove is formed in the right side of the sediment gathering block. The sundry blocking device has the advantages that trash in the sewage can be blocked through sorting, the trash catching efficiency is improved, the siltation caused by the sewage is effectively relieved, and the cleanliness of the sewage flowing to a sewage treatment plant is improved.

Description

technical field [0001] The invention mainly relates to the field of ditch environmental protection, in particular to an environmental protection ditch debris blocking device. Background technique [0002] At present, sewage such as residential water and factory wastewater is transported to sewage treatment plants through ditches for purification. In the process of sewage flowing to the sewage treatment plant, the water flow often carries sediments such as floating objects and sediment. The existing ditch is equipped with a filtering device, usually using a V-shaped filter screen and a sedimentation tank to block the floating debris to the edge for salvage, and make the sediment settle in the sedimentation tank, effectively filtering out the floating garbage and settled garbage, ensuring The smooth flow of water reduces the workload of sewage treatment plants. [0003] However, in the actual flow of sewage, the floating matter and sediment are often entangled together, whic...

AI Technical Summary

Problems solved by technology

[0003] However, in the actual flow of sewage, floating objects and sediments are often entangled together, which easily impacts the filter screen, causing siltation at the filter screen, resulting in more types of settled garbage in the sedimentation tank, increasing the difficulty of salvage and the complexity of treatment.

When the garbage is silted up, the sewage flowing into the sewage treatment plant is highly polluted, which also increases the filtration work of the sewage treatment plant, making the ditch debris blocking effect not good
