Description

Technical Field

[0001] The utility model relates to the technical field of dust removal components, and specifically, to a dust collector filter cartridge that is convenient to disassemble and replace. Background Art

[0002] Filter cartridge dust collectors are widely used in industrial fields such as cement, steel, electricity, food, metallurgy, and chemical industry. Since the advent of filter cartridge dust collectors, the overall dust removal capacity has increased several times, and the filtration area has increased significantly. It is a better solution to solve the problems of traditional dust collectors such as difficult collection of ultrafine dust, high filtration air velocity, poor dust cleaning effect, easy wear and leakage of filter bags, and high operating costs.

[0003] Filter cartridge dust collectors are divided into vertical installation filter cartridge types and inclined insertion filter cartridge types according to the installation method of the filter cartridges. The dust removal filter cartridges used in the inclined insertion filter cartridge types mostly have a structure with a through-hole screw in the bottom cover. When installing and replacing, it is necessary to insert a through-hole screw, and a wing nut is used to lock it outside the through-hole screw by hand. Although this structure can also be replaced by hand, the replacement is not very convenient, and it is even more cumbersome when there are more filter cartridges to be replaced. Content of the Utility Model

[0004] Therefore, the utility model proposes a dust collector filter cartridge that is convenient to disassemble and replace to overcome the above problems existing in the prior art.

[0005] The technical solution of the utility model is as follows:

[0006] A dust collector filter cartridge that is convenient to disassemble and replace includes an end cover, a bottom cover, a filter media layer, and an inner support. The filter media layer and the inner support are arranged between the bottom cover and the end cover, and the inner support is arranged inside the filter media layer; a through-hole is opened in the center of the end cover, a sealing ring protruding in the axial direction is arranged on the outer surface of the end cover, and clamping protrusions protruding in the radial direction are arranged on the outer circumferences of the end cover and the bottom cover; the filter media layer is a cylindrical shape surrounded by folds, and both ends of the filter media layer are adhesively connected to the end cover and the bottom cover respectively; the inner support is a porous rigid structure, and the inner support is rigidly connected to the end cover and the bottom cover respectively; an inward depression is arranged in the middle of the bottom cover, and a cross-shaped turning handle in the shape of a crossbeam is arranged in the middle of the depression. The cross-shaped turning handle is integrated with the surface of the depression, dividing the depression into two non-connected spaces.

[0007] As a preference, the dust collector filter cartridge that is convenient to disassemble and replace further includes an outer support. The outer support is arranged outside the filter media layer. The outer support is a porous rigid structure, and the outer support is rigidly connected to the end cover and the bottom cover respectively.

[0008] As a preference, the dust collector filter cartridge that is convenient to disassemble and replace further includes a snap ring. The snap ring is sleeved in the middle of the filter media layer, and there are two or more snap rings; the inner support is a wire mesh, and both ends of the inner support are welded and fixed to the end cover and the bottom cover respectively; the filter media layer is a wood pulp fiber filter paper layer.

[0009] As a preference, the dust collector filter cartridge that is convenient for disassembly and replacement further includes a snap ring. The snap ring is sleeved in the middle of the filter media layer, and there are two or more snap rings; the inner support is a perforated plate, and both ends of the inner support are connected to the end cap and the bottom cover by screws; the filter media layer is a synthetic fiber non-woven filter media layer.

[0010] The working principle and beneficial effects of the present utility model are as follows:

[0011] For the dust collector filter cartridge that is convenient for disassembly and replacement provided by the present utility model, when in use, the dust-containing gas enters from the outside of the filter media layer into the inside of the filter media layer. The dust is blocked by the filter media layer, and the purified air flows out from the through holes at the end cap. The sealing between the end cap and the bottom cover and the dust collector body needs to be realized through the cooperation between the dust collector filter cartridge and the body. A sealing ring is required between the body and the end cap and the bottom cover. The sealing ring can be arranged on the dust collector filter cartridge or on the body. The dust collector filter cartridge of the present utility model has the advantage of being very convenient to replace. When replacing or installing, just insert the dust removal filter element and rotate and snap the dust collector filter cartridge by grasping the flat wrench to complete the installation.
