A filter element of an electromagnetic filter and a purification method thereof

Abstract

The invention provides a filter core element for an electromagnetic filter. The filter element comprises an inner layer and an outer layer, wherein the inner layer is a rotary drum filter core, the outer layer is an outer drum with solenoid coils, two ends of the rotary drum filter core are respectively provided with a technological lubricating fluid inlet and a technological lubricating fluid outlet, one end of the rotary drum filter core is also connected with a driving motor, a sealed collection chamber is located between the inner layer and the outer layer, and the solenoid coils are located out of the collection chamber. The invention also provides a purifying method for the filter core element for the electromagnetic filter. With the filter core element for the electromagnetic filter and the purifying method, the problem of generation of a great amount of waste water in the process of backwashing of the filter core is overcome on the premise that high-efficiency technological performance of the electromagnetic filter is maintained.

Description

technical field [0001] The invention relates to the field of metallurgical machinery and equipment, in particular to a filter element of an electromagnetic filter and a purification method thereof. Background technique [0002] In the steel rolling mill, the process lubrication system has a great influence on the energy consumption, oil consumption, production emissions and product surface quality of the mill. The rolling mill will continuously produce iron powder during the production process, which is washed down by the process lubrication system and continuously accumulated in the process lubrication system. These continuously produced iron powder will pollute the process lubrication system, affect the performance of process lubrication, reduce the surface quality of strip steel, and increase the emission of the unit. In order to avoid the above problems, the process lubrication system of steel rolling is generally equipped with a magnetic filter device to filter out the...
