Description

Technical Field

[0001] The utility model relates to the technical field of high-efficiency filters, in particular to an adjustable and convenient filter. Background Art

[0002] Air filters are mostly used for environmental dust removal of industrial flue gas. Air filters are divided into bag air filters, plate air filters and box air filters according to their different composition structures. Under the same filter material, bag-type and plate-type purifiers are lower in cost than box-type purifiers and occupy 60-70% of the market.

[0003] The existing plate-type air filter is generally composed of a side frame and filter cotton, which has the following disadvantages: 1. The frame strips need to be trimmed, that is, the two ends of the frame strips need to be trimmed to 45 degrees so that the contact ends of the mutually perpendicular frame strips can match; 2. During the installation process, it is often difficult to align the two installation frame strips; 3. When the two installation frames are often fixed with a locking device, the rivets need to be manually calibrated, the accuracy is low, and the locking is unstable, which seriously affects the air filtration effect; in addition, too many parts such as rivets or screws are used for connection, and their falling off will cause greater damage to the compressor. Furthermore, the plate-type air filter has a small filtering area and a limited dust holding capacity, which makes the smoke filtering effect less than ideal. In response to the above problems, people invented patent number: CN201821878080.0, which discloses a plate-type high-efficiency air filter that is easy to disassemble and assemble. The connection method of the filter is simple, reliable, and easy and quick to disassemble and assemble. It avoids the cumbersome connection method of traditional plate-type air filters, and reduces screws or rivets to prevent them from falling off and causing damage to the compressor. In addition, the filter paper is made of multiple layers of cotton fibers to form a dense skirt type, which increases the windward area, reduces resistance, and enhances the filtration efficiency, making it widely used in air-conditioning and ventilation systems.

[0004] However, the existing filters still have the following problems: 1. The filter specifications are mostly fixed, and they cannot be adjusted and installed according to the specifications of the filter paper, and their applicability is low; 2. The outline dimensions of the existing filters are mostly fixed, and they cannot be adapted and installed according to the specifications of the installation port. The customization cost is high, the reuse rate is low, and it cannot meet the use requirements of the existing filters. Utility Model Content
