Description

Air pipeline coarse filter

Technical Field

The utility model belongs to the technical field of air cleaner, especially, relate to an air duct coarse filter.

Background

Currently, the current state of the art commonly used in the industry is such that: the existing paint room and the primary filter of the shot blasting machine have two types, one type is a rectangular covering coarse filter cotton type on an indoor trench of the paint room, and the other type is a cabinet-mounted honeycomb type coarse filter cotton device. The coarse filter cotton is covered, the defect of large wind resistance is caused due to the thick filter cotton, the coverage area is large, the suction is insufficient, and the dust removal efficiency is greatly influenced; the cabinet honeycomb type coarse filter occupies too much space resources due to large volume.

In summary, the problems of the prior art are as follows:

(1) the cover coarse filtration cotton type, thereby because the big shortcoming of windage that leads to of filter pulp thickness, the coverage area is big, leads to the suction not enough, and dust collection efficiency is low.

(2) The cabinet honeycomb type coarse filter has large volume and occupies excessive space resources.

The difficulty and significance for solving the technical problems are as follows: the utility model overcomes the not enough of background art provides a simple structure is reasonable, can very effectively practice thrift the space resource, can improve filtration efficiency again.

SUMMERY OF THE UTILITY MODEL

To the problem that prior art exists, the utility model provides an air duct coarse filter.

The utility model discloses a realize like this, a thick filter of air conduit includes the core bone spare, the upper end of folding wing spare is connected with sticky mode in the core bone spare outside, it has the plum blossom flange to paste with sticky mode to fold wing spare inboard, be provided with the arc between each flap spare.

Furthermore, the flap piece is made of air primary-effect flame-retardant filter cotton g1-4, the upper part is large, the lower part is small, the flap piece is only provided with an opening, the flap piece is uniformly distributed on the plum blossom flange, the spacing distance between each flap piece is the same, and the opening of each flap piece is tightly adhered to the plum blossom flange by special adhesive.

Further, the core bone piece is provided with a bottom without a cover and is made of air primary flame retardant filter cotton g 1-4.

Further, the arc-shaped plate material is Q235A.

Furthermore, the plum blossom flange is made of Q235A, a completion sheet is arranged on the plum blossom flange, and the completion sheet is made of air primary-effect flame-retardant filter cotton g 1-4.

Furthermore, the completion sheet can be detached.

In summary, the advantages and positive effects of the invention are: the utility model has large filtering area, is very suitable for the coarse filtering of the pipeline, and can enlarge the cross section area of the pipeline by more than 300 times; the resistance is small, and the pressure of the fan is hardly reduced; the device can completely replace a coarse filter cabinet device, reduces the occupied space of the environment-friendly device, and saves precious space development resources for users; the air flow is stable and does not oscillate, so that the filtering quality is ensured; the coarse filtration cost is reduced; the filter cotton is convenient to clean and replace.

Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.

The coarse filter mainly adopts the umbrella-shaped filtering mode of the design of the umbrella-shaped structure, the resistance is very small, the pressure of the fan is hardly reduced, the filtering area is greatly increased, and filtering cotton which is more than 300 times of the cross section area of the pipeline is arranged in the very limited pipeline space; and the coarse filter is arranged in a pipeline, so that the space resource of a user is greatly saved.

As shown in fig. 1, the utility model discloses a core bone spare 2, the upper end of folding wing spare 1 is connected with sticky mode in the core bone spare 2 outside, and folding wing spare 1 inboard is pasted with plum blossom flange 3 with sticky mode, is provided with arc 4 between each folding wing spare 1, and it is adjacent when preventing adjacent folding wing spare 1 overwind inflation, leads to reducing filter area.

Preferably, the folding wing pieces 1 are made of air primary-effect flame-retardant filter cotton g1-4, the upper part is large, the lower part is small, only the lower part is provided with an opening, the folding wing pieces are uniformly distributed on the plum blossom flange 3, the spacing distance between every two folding wing pieces 1 is the same, and the opening of every folding wing piece 1 is tightly adhered to the plum blossom flange 3 by special adhesive.
