Backwash filtering device of rolled oil of stainless steel rolling mill

Abstract

The invention discloses a backwash filtering device of rolled oil of a stainless steel rolling mill. The backwash filtering device of rolled oil of a stainless steel rolling mill comprises a filtering cylinder body; the filtering cylinder body is provided with a filtering cylinder cap which is provided with a gas opening and is connected with a steel pipe; the filtering cylinder body is internally provided with four filtering plate which are divided into four layers, each layer of the filtering plate is provided with 832 backwash filtering element; the filtering plates are arc; the upper part of the filtering cylinder body is provided with an overflow opening and a filtering plate backwash oil opening; the lower part of the filtering cylinder body is provided with a sump oil inlet, a self-circulation oil opening and a liquid level sensor. The backwash filtering device of rolled oil of the stainless steel rolling mill, which is provided by the invention, is high in filtering precision, is good in efficiency, can improve the secondary utilization of rolled oil, comprises more filtering elements, and can backwash a great amount of rolled oil once; moreover, the filtering plates are arc, and impurities on the surface of the filtering plates can flow down along the filtering plates.

Description

[0001] technical field [0002] The invention specifically relates to a stainless steel rolling mill rolling oil backwash filter device. Background technique [0003] The structure of the traditional stainless steel rolling oil filter device is relatively simple, and the impurities attached to the outer surface of the filter layer can not be removed, and the impurities in the filter tank cannot be cleaned; thus, the normal filtration capacity and filtration capacity of the filter layer cannot be guaranteed. It is not enough, as the filtering accuracy and filtering efficiency of rolling lubricating oil are not ideal, the utilization rate of rolling oil is poor, and the filtering accuracy of rolling oil will directly affect the quality of products. Contents of the invention [0004] Purpose of the invention: In order to solve the deficiencies of the prior art, the present invention provides a stainless steel rolling mill rolling oil backwash filter device. [0005] Technica...
