Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The utility model discloses a preferred embodiment of a section of thick bamboo is strained in dust removal of recoverable inner network structure, as shown in fig. 1 to 5, this section of thick bamboo is strained in dust removal of recoverable inner network structure includes urceolus structure and inner network structure, and inner network structure coaxial arrangement is in urceolus structure.

The outer cylinder structure comprises a filter material 1, an elastic rubber head 2 and a bottom cover 3, a rubber filling layer 4 is uniformly arranged between the filter material 1 and the elastic rubber head 2 and between the filter material 1 and the bottom cover 3, the rubber filling layer 4 can increase the sealing performance between the filter material 1 and the elastic rubber head 2 and between the filter material 1 and the bottom cover 3, the filter material 1, the elastic rubber head 2 and the bottom cover 3 are fixedly bonded through the rubber filling layer 4, an integrated structure is formed, and the outer cylinder structure forms a supporting foundation of the dust removal filter cylinder. The filter material 1 is made of filter paper, the filter paper is folded into a W-shaped structure, and two ends of the filter paper are respectively bonded and fixed with the elastic rubber head 2 and the bottom cover 3. Bandage 5 is glued to the outside of filter paper still hot melt adhesive, and bandage 5 has a plurality ofly arranged along the axial interval of filter material 1 to increase the structural strength of filter material 1.

The filter paper encloses into tubular structure, and the hole of filter paper forms the wind channel that supplies the air current circulation, and head 2 is glued to the elasticity is the annular structure, and the hole of head 2 is glued to the elasticity communicates with the wind channel in order to supply the gas circulation. The bottom integrated into one piece of head 2 is glued to elasticity has the interior ring platform 21 of inside extension, and interior ring platform 21 forms the axial that is used for hanging interior network structure and keeps off the platform, in other embodiments, also can glue on the inner wall of head 2 along its circumference interval arrangement a plurality of brace tables on elasticity, and the brace table forms the axial and keeps off the platform. First 2 is glued in elasticity still bonds in the bottom of inner ring platform 21 and is fixed with tip intranet 6, and tip intranet 6 is the material of moulding plastics, and tip intranet 6 extends to the direction of bottom 3, and tip intranet 6 extends to the wind channel of filter material 1, and tip intranet 6 arranges between intranet structure and filter material 1, guarantees at the in-process of changing, reduces the friction between intranet structure and the filter material 1, guarantees that filter material 1 does not receive the damage. The elastic rubber head 2 is made of polyurethane material, and has good temperature resistance, stable property and long service life.

The bottom cover 3 is of a T-shaped structure, the bottom cover 3 comprises a main body 31 and a stand column 32 arranged on the inner side of the main body 31, the inner side is one side close to the air duct, the main body 31 and the stand column 32 are of an integrated structure, and the main body 31 and the filter material 1 are fixedly bonded through an encapsulating layer 4. The column 32 is a stepped structure with a top outer diameter smaller than a bottom outer diameter, the upper part of the column 32 is defined as a small-diameter section 321, the lower part of the column 32 is defined as a large-diameter section 322, and the small-diameter section 321 and the large-diameter section 322 are in smooth transition through a conical surface. Because contaminated air gets into the inner network structure through filter material 1 and passes through the wind channel again and is glued head 2 exhaust clean air by elasticity, it all attaches at filter material 1 surface to filter the dust, the working resistance of a dustproof section of thick bamboo of straining, pressure differential increases, lead to this section of thick bamboo of straining that removes dust can become invalid, just will pass through the reverse jetting of pulse gas, clear away the dust on filter material 1 surface, dust is down sunken in a section of thick bamboo bottom under the effect of self gravity, keep away from the jetting mouth at a section of thick bamboo top, the deashing is difficult, stand 32 wholly is the toper design, do benefit to the pressure direction that changes bottom jetting air current, thereby improve the deas.

The inner net structure comprises an inner net body 7 and an end flange 8, the end flange 8 and the inner net body 7 are both of metal structures, and the end flange 8 is fixed on the top of the inner net body 7 through spot welding.
