Embodiment Construction

[0010] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0011] Such as figure 1 As shown, a novel air filter bag according to the present invention mainly includes two parts: a large filter bag 201 and a small filter bag 202. The small filter bag is located inside the large filter bag, and its filtering area is 50% of the large filter bag. Bonding by hot melt, filter pouches are also bonded by hot melt. The present invention does not need to replace the filter frame under the condition of small volume of the air-conditioning box and large air volume. Adding the filter pouch process in the conventional filter bag is equivalent to increasing the filter area by 50% in the original filter surface, and using The high-frequency technology hot-melts the bag sheets to enhance the ventilation strength of the b...

Abstract

The invention discloses a novel air filter bag which mainly comprises a large filter bag and small filter bags, wherein the small filter bags are positioned in the large filter bag; the filter area of each small filter bag is 50 percent of that of the large filter bag; the small filter bags are adhered to the large filter bag through thermal melting; the small filter bags are also adhered to one another through the thermal melting. Under the conditions that an air conditioning box is small and the air volume is large, a filter frame is not required to be replaced; a small filter bag page technology is additionally adopted in a conventional filter bag page, so that 50 percent of the filter area is increased in the original filter area; furthermore, bag pages are adhered to one another through the thermal melting by using a high-frequency technology; the ventilating intensity of the bag pages is improved; at high air speed, the filter effect can not be affected by the adhesion of the bag pages; the aims of saving energy and reducing the cost are fulfilled.

Description

technical field [0001] The invention relates to the technical field of air purification devices, in particular to a novel air filter bag, which is applied to various air purification equipment. Background technique [0002] As a filter element, the filter bag is a key part of the filtration process. The quality of the filter bag largely determines the filtering effect of the user. The application document with the application number 00220835 discloses a high-strength dust filter bag, including a cylindrical bag body sewn from filter cloth, the filter cloth is interwoven by warp yarns and weft yarns, and its improvement is the The weft yarn is formed by twisting a group of glass fibers with a group of flexible synthetic fibers. However, this filter bag only improves the prior art in terms of material, and is no different from the traditional filter bag in terms of structure, which also limits the further improvement of the filter bag in filtering performance. [0003] In su...
