A kind of circular bag filter and its manufacturing method

Abstract

The invention discloses a round bag shaped filter and manufacturing method thereof, and is characterized in that the filter is composed of a barrel-shaped support and filter bags arranged in the barrel-shaped support through a hanging mechanism; the barrel-shaped support is composed of a supporting ring, a bottom pattern plate and a supporting rod connected between the supporting ring and the bottom pattern plate and arranged in a peripheral mode, and a plurality of round filter bag connecting openings are formed in the bottom pattern plate; the hanging mechanism is composed of a disc receiving seat, filter bag upper receiving discs installed on the disc receiving seat and a plurality of extension springs connected between the disc receiving seat and the supporting ring. The filter bag upper receiving discs and filter bag lower catching rings in the round bag shaped filter adopt sheet steels and use a flow forming technology to be formed. The round bag shaped filter is slight and handy in design, compact in structure, small in occupied space, light in weight, capable of achieving dust cleaning by vibrating, simple, convenient and practical, and suitable for situations which are small in air quantity and have a strict requirement for contour dimension of equipment and weight.

Description

technical field [0001] The invention relates to the field of air purification treatment, in particular to a circular bag filter and a manufacturing method thereof. The filter is especially suitable for use in small air purification devices, and can be installed in a small installation space and has strict requirements on the external dimensions and weight of the equipment. use on occasions. Background technique [0002] At present, the bag filter used in the dust removal system has relatively large air volume and external dimensions. In the occasions where the air volume is small and the equipment shape and weight must not exceed a certain limit, there is no suitable bag filter for selection. Other dust removal equipment either has relatively large dimensions and weight, or the dust removal efficiency is not high. Some occasions that require local purification urgently need bag filters with light design, small size, light weight and high dust removal efficiency. Contents ...
