Abstract

The invention relates to an oil filter of nonferrous metal foil rolling industry, comprising a sump oil pool or a sump oil tank, an oil cleaning pool or an oil cleaning tank, and an oil filtering system, wherein the oil filtering system comprises a coarse filtering oil-water separation device, a fine filtering destaining device, a buffering tank and a vacuum pump; the oil outlet of the coarse filtering oil-water separation device is communicated with the fine filtering destaining device through a pipeline, the oil inlet of the coarse filtering oil-water separation device is communicated with the sump oil pool or the sump oil tank by the pipeline or a piping pump, the oil outlet of the fine filtering destaining device is communicated with the upper part of the buffering tank by a pipeline, the oil cleaning pool or the oil cleaning tank is communicated with the lower part of the buffering tank, and the vacuum pump is communicated with the top part of the buffering tank by a pipeline. The oil filter of the invention can realize on-line cycle operation, does not need to add filter aid duty to duty, and does not need to change filter cloth day to day, thereby not only saving a great amount of funding, but also avoiding economic loss caused by machine halt. The oil filter has no effluent discharge, high automation degree, easy control, simple structure and convenient operation, reduces labor intensity for workers, and is beneficial to environment protection and promotion and implementation.

Description

1. Technical field:

[0001] The invention relates to a rolling oil purification system in the nonferrous metal processing field, in particular to an oil filter in the nonferrous metal foil rolling industry. 2. Background technology:

[0002] At present, plate and frame filter presses are mostly used to process circulating rolling oil in the non-ferrous metal plate and foil rolling industry to ensure the quality of oil recycling. This type of equipment integrates automatic oil inlet and outlet filtration and operates online, but filter aids (diatomaceous earth, activated clay) must be added, which needs to be added in shifts and replaced every day. The filter cloth and filter soil frequently produce slag, especially the filter aid takes away a large amount of rolling oil, resulting in a great degree of waste. For example, based on the production scale of 5 rolling mills, the existing technology needs to consume about 1 ton of diatomite per day, and about 1 ton of unseparated ...
