Problems solved by technology

Frequent slagging of filter cloth and filter soil, especially the filter aid takes away a large amount of rolling oil, resulting in a large 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 oil is carried in the diatomite, and the filter cloth used for filtration is about 50m 2 , the market price of diatomite is 2,800 yuan / ton, and the value of waste oil is about 8,000 yuan per ton, and the total daily filtration cost exceeds 10,000 yuan
The existing filtration technology not only wastes resources and increases costs, but also causes environmental pollution, and it also takes a lot of manpower to dispose of the filtered garbage

Embodiment 1

[0031] Embodiment one: see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 6-1 , an oil filter machine for the non-ferrous metal foil rolling industry, including a dirty oil pool 5, a clean oil pool 6, and an oil filtering system, the oil filtering system includes a coarse oil-water separation device 2, a fine filter decolorization device 3, a buffer tank 1 and communication with it Vacuum pump 4, the filtration process of the oil filtration system is to discharge dirty oil from the rolling mill → dirty oil pool 5 → coarse filter oil-water separation device 2 → fine filter decolorization device 3 → buffer tank 1 → oil well pump 32 → clean oil pool 6 → rolling mill. Wherein the buffer tank 1 is communicated with the vacuum pump 4 to ensure that the buffer tank 1 is in a negative pressure state during operation.

[0032] A dehydration mechanism is installed in the coarse filter oil-water separation device 2, and the dehydrated dirty oil is intr...

Embodiment 2

[0041] Embodiment two: see figure 1 , Figure 4 , Figure 5 , Image 6 , Figure 6-1 , Figure 7 , Figure 8 , the numbering is the same as in Embodiment 1, the meaning is the same, and the same parts will not be repeated. The difference is that multiple rows of decolorizing and impurity-removing filter cores 26 are installed in the cavity of the fine filter and decolorization device 3, and the cavity of the fine filter and decolorization device is covered by a horizontal The support plate 37 is divided into upper and lower two fully enclosed cavities, which are respectively a negative pressure chamber 35 and an oil chamber 36, and a solenoid valve for discharging residual pressure is arranged on the negative pressure chamber. The suction tubes 30 at the upper ends of the decolorizing and impurity-removing filter elements 26 are respectively fixed on the support plate 37 , and the suction tubes 30 communicate with the negative pressure chamber 35 . The net oil extraction...

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 ...
