Barrel type filter

Abstract

The invention discloses a barrel type filter which structurally comprises a circular filtering net, primary antibacterial layers and a gradient folded composite filtering material, wherein the gradient folded composite filtering material takes the shape of a cup which shrinks gradually from top to bottom and is opened up and down; the circular filtering net is arranged at the top of the gradient folded composite filtering material; the primary antibacterial layers are arranged on the outer surfaces of the circular filtering net and the gradient folded composite filtering material, respectively; the gradient folded composite filtering material is of an integral structure and consists of a plurality of filtering material folding units connected in a circumferential direction in sequence. Thebarrel type filter has the advantages that due to the characteristic that a barrel type filter is compact in structure self, the utilization rate is increased, and a fluid is uniformly filtered; thecircular filtering net is arranged at one end of a barrel, resistance differences are achieved through gradient folding of the filtering net around the barrel, an air fluid is adjusted and distributeduniformly, and high efficiency and high dust capacity property of the filtering net are achieved.

Description

technical field [0001] The invention relates to a barrel filter. Background technique [0002] With the development of society and the increasingly prominent problems of environmental pollution, people pay more and more attention to the prevention and control of environmental pollution, which has brought about the continuous expansion of the air filter market. The filter screen is the core component of the air filter and will directly affect the quality of the air. Filter efficiency and effectiveness. Barrel filter is a kind of air filter with compact structure, but the filter screen of traditional barrel filter in the prior art is generally surrounded by discount filter material or odor filter material, and one of the two ends is an end cap Or both ends are open, so there will be a waste of space at both ends and the uneven distribution of fan suction will cause fluid turbulence, which will affect the filtration efficiency. Contents of the invention [0003] The present...
