Liquid core-type filter

Abstract

The invention discloses a liquid core-type filter comprising a cylinder body and a filter screen; the filter screen is arranged in the cylinder body; the upper end of the cylinder body is provided with a feed port, the lower end of the cylinder body is provided with a discharge port, and the lower end of the cylinder body is provided with a triangular supporting frame for supporting the cylinder body on the ground; the outer side of the filter screen is provided with an annular supporting cylinder, and the wall of the supporting cylinder is provided with a plurality of uniform-distribution liquid flowing holes; the filter screen is close to the inner wall of the supporting cylinder, a plurality of fixing bars are arranged on the inner side of the filter screen and tightly press the filter screen on the inner wall of the supporting cylinder, and the filter screen is internally provided with a rotary cleaning scraping plate mechanism. The liquid core-type filter overcomes the defects of the prior art, and is reasonable in design and compact in structure; the cylinder body interior is subjected to a special structural design, and the filter screen is fixed at the middle of the cylinder body and is provided with the rotary scraping plate mechanism, so that automatic cleaning and slag scraping can be achieved, online operation is achieved, liquid loss is less, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of liquid filtering equipment, in particular to a liquid core filter. Background technique [0002] Liquid filter is a device commonly used on pipelines conveying liquid media to eliminate impurities in liquid media. When the liquid enters the filter with the filter device, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. Since the filtered medium in the liquid is generally left inside the filter, it is necessary to clean the filter regularly to ensure its normal operation. In the liquid filter in the prior art, the filter cover and the container are fastened by screws, and the process of disassembling the cover is relatively complicated. Therefore it is inconvenient and slow to replace the filter bag in the container. And the filtering accuracy of the previous filter is not high, so it cannot meet the requirements of some fine filtering. In addition, the filter ty...

In the liquid filter in the prior art, the filter cover and the container are fastened by screws, and the process of disassembling the cover is relatively complicated

Therefore, it is inconvenient and slow to replace the filter bag in the container

And the filtering accuracy of the previous filter is not high, so it cannot meet the requirements of some fine filtering

In addition, the slag removal cannot be carried out in the filter type, and cleaning work is required, and the production efficiency is low
