Abstract

The invention relates to the technical field of oily wastewater treatment, and particularly discloses an automatic backwash degreaser which comprises an inlet section, a filter section and an oil discharge section, the inlet section is fixedly connected with the filter section, and the filter section is connected with the oil discharge section through a flange; a framework is arranged in the filter section, the whole framework is of an annular structure, and a filtering net is arranged on the outer side of the framework; an oil discharging disc is arranged at the joint of the filter section and the oil discharging section and connected with an output shaft of the motor. A water outlet is formed in the side surface of the filter section; an oil outlet is formed in the side surface of the oil discharging section; an end cover is arranged at the end of the oil discharging section, and the motor output shaft penetrates out of the end cover and is connected with the motor. According to the invention, denatured and useless grease can be filtered, blocked, backwashed and discharged so that the purpose of cleaning circulating water, emulsified liquid and rinsing water is achieved; the device is simple in overall structure and excellent in treatment effect, the oil concentration in the treated wastewater is greatly reduced, and pollution caused after discharge is avoided.

Description

technical field [0001] The invention relates to the technical field of oily wastewater treatment, in particular to an automatic backwash oil remover. Background technique [0002] During the production process of hot rolling and cold rolling of steel plates, due to technological requirements, a large amount of oily waste water is produced every day, including turbid ring water, rolling emulsion, lye and rinsing water, etc. Because it contains a large amount of denatured and useless oil, whether it is recycled or discharged, this oil has become a difficult point to remove. [0003] At present, oil exists in water mainly in the following forms: 1. Suspended oil. The diameter of oil droplets is greater than 100 microns. Due to the large particles, it is easy to float on the water surface. 2. Disperse the oil, the diameter of the oil droplet is between 10-100 microns, and it can form an oil slick after standing in water for a period of time. 3. Emulsified oil, with a diameter ...
