Description

Technical Field

[0001] The utility model relates to the technical field of water treatment in steel plants, in particular to a sediment cleaning device for an intermediate water pool in a water treatment plant. Background Art

[0002] Water treatment in steel mills is a complex and important process, which aims to effectively remove harmful substances from wastewater through different treatment processes and technologies. In the pretreatment stage of water treatment, sewage is filtered through the filter tank and then enters the intermediate water tank, and then is lifted to the multi-media filter for filtration by the lifting pump. During the process of the previous filter tank, due to long-term operation, the sealant at the gap between the filter plates will fall off, causing quartz sand or silt to enter the water production pipe through the gap, and then enter the intermediate water tank. The silt accumulates and settles at the bottom of the pool, which is not only easy to block the suction port of the lifting pump, but also affects the water quality. The staff on duty need to enter the bottom of the pool to clean the silt every once in a while. Due to the limited working space and the deep bottom of the pool without air circulation, there are operational risks and suffocation hazards for the staff. Utility Model Content

The movable contact part between the scraping blade 1 and the bottom of the pool 3 can also be provided with a rubber, which has a certain elasticity and can be pressed against the bottom of the pool 3, so as to better scrape the mud.

[0023] There are two scraper blades 1, which are respectively arranged on the two slopes of the V-shaped slope and connected to each other by a pull rope 8; there are two drive components, which are respectively connected to the two scraper blades 1. The drive component consists of a first capstan 6 and a fixed pulley 7. The first capstan 6 is arranged at the side of the top of the pool 3, and the fixed pulley 7 is arranged at the side of the bottom of the pool 3.
