[0002] In the metallurgical industry, the turbid water system is mainly used for direct cooling of equipment. Turbid water is mainly used for direct cooling of rolling mill equipment to ensure that the temperature of the rolling mill equipment can be effectively controlled during operation, thereby improving production efficiency and extending the service life of the equipment. Since the turbid water system involves water circulation that is in direct contact with the cooled material or equipment, impurities and dirt will be entrained in the water, so it is necessary to use a clarifier (also known as a precipitator) to clarify the turbid water.

[0003] When the turbid circulating water system is in operation, due to oil leakage or local oil discharge of the equipment, the amount of floating oil in the system water is too high. The existing clarifier cannot discharge the floating oil in time, and manual cleaning is required. One of the manual cleaning methods is that the operator uses a bucket to manually remove the floating oil; another manual cleaning method is that the operator uses a water pump to hang below the water surface to drain the water.

[0004] In view of this, the inventor has designed a clarifier based on many years of production design experience in this field and related fields and through repeated experiments, in order to solve the problems existing in the prior art. Utility Model Content
