Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for cold rolling filtration, and in particular relates to an auxiliary device for post-processing filter cakes of a plate filter. Background Art

[0002] When the cold rolling mill rolls pure aluminum, there are many small solid particles in the rolling oil, which are the main cause of pinhole defects in aluminum foil. The main cause of annealing white spots is the small solid particles larger than 4μm. The aluminum particles smaller than 8μm in the rolling oil are the cause of the rolling oil turning black. The more the number, the more serious the blackening, which eventually leads to surface damage of the rolled product and difficulty in plate surface inspection during the process.

[0003] In order to eliminate the harmful effects of solid particles, metal soaps and other contaminants in rolling oil, the most effective treatment method in the industry is filtration. Diatomaceous earth and activated clay are commonly used as filter aids, and non-woven fabrics are used as filter media to filter rolling oil. This can keep the rolling oil clean and provide favorable rolling oil protection for obtaining products with high surface quality. This process first pre-coats to form a pre-coat filter cake of a certain thickness on the filter paper. The pre-coat maintains a very small gap, and the filtering effect is formed on the surface of the pre-coat. As the filter layer thickens, the pressure of the filter box continues to increase. When it reaches a certain pressure, the filtering process ends, and the filter paper should be replaced, and the dirty soil filter cake should be cleaned at the same time. Specifically, a layer of filter paper is laid between each layer of the filter box, and a layer of filter aid is pre-coated on the filter paper. The dirty oil is purified into clean oil through the filter aid and filter paper, and returned to the clean oil tank of the underground oil depot for recycling by the cold rolling mill.

[0004] There are two main ways to replace filter paper at present. One way is to press the cover plate on the filter paper to lift it, and then roll up the filter paper through the winding roller. The other way is to first lift the dirty soil box to the edge of the filter box, then lift the filter cover plate, manually drag the used filter paper and the attached filter cake into the dirty soil box, then take the dirty soil ton bag, manually shovel it into the dirty soil ton bag, and lift the dirty soil ton bag to a temporary storage area for centralized treatment. Since the filter paper is collected and processed by winding up the winding roller, the filter cake on the surface of the filter paper is broken and falls off during the winding process. On the one hand, the collection and processing of the filter cake cannot be realized, and on the other hand, the fallen filter cake residue is difficult to clean. Therefore, the latter method is currently used to collect and process the filter paper and filter cake. However, this method also has the following problems:

[0005] 1. The processing process of this treatment method includes lifting the dirty soil box, manually pulling the filter paper and filter cake into the dirty soil box, manually shoveling the filter paper in the dirty soil box into a ton bag, and lifting it to a temporary storage area. The steps are cumbersome, the processing time is long, and the efficiency is low;

[0006] 2. A large amount of work is done manually, resulting in high labor intensity for workers;

[0007] 3. When the filter paper is manually shoveled into the ton bag, the filter cake is broken and it is impossible to ensure that the dirty soil will not fall off, which makes subsequent cleaning troublesome;

[0008] 4. The filter cake breaks and falls during the process of shoveling from the dirty soil box into the ton bag, generating dust. Summary of the invention
