Vacuum filter of fine-mesh crumb collecting layers and use method thereof

Abstract

The invention discloses a vacuum filter of fine-mesh crumb collecting layers and a use method thereof. The vacuum filter is arranged in a sewage tank, and a main support frame of the vacuum filter is supported on the sewage tank; a water purifying pipe is welded on the main supporting frame and arranged in a tooth ring, a tooth ring seat, a water absorbing tank and a filtering framework from top to bottom; the tooth ring is fixedly connected with the tooth ring seat; the tooth ring seat is connected with the water absorbing tank arranged under the tooth ring seat by a channel column; the water absorbing tank is connected with an end flange of the filtering framework by bolts; the water purifying pipe is respectively sealed connection with the water absorbing tank and the filtering framework by a friction subassembly, a seal subassembly I and a seal subassembly II which are sleeved on the water purifying pipe; a back-flushing pipe is arranged in the middle of the water purifying pipe; and inner and outer scraping plate devices are arranged at the lower part of the water purifying pipe and freely connected with a filtering fine mesh. When the vacuum filter works, if the crumb collecting layers are accumulated as a certain thickness on inner and outer filtering meshes to cause a vacuum degree in a suction chamber to achieve -0.27bar, an air cylinder is used for driving a push rod, and the tooth ring is pushed to rotate 3 degrees anticlockwise; and after a section of the crumb collecting layer is scraped by a scraping plate, a filtering process starts again.

Description

technical field [0001] The invention relates to a filtering device for separating cuttings and cooling liquid in a centralized cooling liquid treatment system, which is used for centralized processing of cooling liquid in machining production and filtering of cleaning liquid of industrial cleaning machines. Background technique [0002] At present, in the field of machining-intensive manufacturing, many manufacturers have to centralize the chips generated in the machining process together with the coolant. Filtration is a very important process in the coolant centralized treatment system. At present, the filter devices used in wet processing in the field of domestic production and manufacturing are: [0003] 1. The linear gap automatic recoil filter has the following disadvantages: [0004] a. The working state is continuous rotation and recoil, and no debris layer will be formed for deep filtration. The filtration accuracy can only depend on the size of the filter medium ...

AI Technical Summary

Problems solved by technology

[0018] a. Side leakage is easy to occur on both sides of the circulation belt, and it is not easy to detect. After side leakage occurs, the filtration accuracy will be lost;

[0019] b. If higher filtration accuracy is required, it needs to be supplemented with disposable paper tape for filtration, and the waste paper tape is not easy to rot, and the emission is restricted by environmental protection;

[0020] c. The circulating belt vacuum filter needs to be equipped with a clean water tank in order to realize the cooling liquid supply during filtration and regeneration, which occupies a large area and has relatively poor reliability.

[0021] In view of the problems existing in the above-mentioned types of domestic filter products, and the low cost performance, they are not suitable for large-scale continuous production; and the filtering effect is affected by factors such as system flow, pressure and daily maintenance. Therefore, in mass production At this time, the contradictions of low efficiency, unstable filtering effect and poor economy are more prominent, so a new fine-meshed debris layer vacuum filter is needed to meet the needs of large-scale continuous production
