Detailed Description

In order to make the implementation purpose, technical solution and advantages of the present invention clearer, the following will clearly and completely describe the technical solution of the present invention with reference to the embodiments of the present invention and the accompanying drawings. The embodiments recited in the present application are only a part of the embodiments of the present application, and should not be considered as all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any inventive step, are within the scope of the present invention, and therefore the following detailed description of the specific embodiments, which is provided in the accompanying drawings, is not intended to limit the scope of the invention as claimed, but merely represents a preferred embodiment of the invention.

The utility model provides a fire-retardant multi-layer filter cotton of high temperature resistant, includes the first filter layer 1 of tube-shape, 1 one end opening of first filter layer, and the other end is the toper structure, and the opening part of first filter layer 1 is equipped with first fire-retardant net 2, and the inboard interval of first filter layer 1 is equipped with a plurality of second filter layers 3, and second filter layer 3 is the toper structure.

In the scheme, the filtering parts of the first filtering layer 1 and the second filtering layer 3 are both arranged in a tapered structure, so that air passing through the filtering layers concentrates dust at the edge or the middle part, the filtering effect is kept for a long time, and the high-temperature-resistant and flame-retardant performances of the first filtering layer 1 and the second filtering layer 3 are improved by matching with the first flame-retardant net 2 at the end part of the first filtering layer 1.

In order to facilitate understanding of the technical solutions of the present invention, the following examples are further illustrated.

The first embodiment is as follows:

referring to fig. 1, in this embodiment, the opening end of the first filter layer 1 is an air outlet, and the tapered end surface of the first filter layer 1 is an air inlet. And a second flame-retardant net 4 is arranged on the conical end surface of the first filter layer 1, and the second flame-retardant net 4 is also in a conical structure.

The air passes through fire-retardant net 4 of second, first filter layer 1, a plurality of second filter layer 3 and first fire-retardant net 2 in proper order, and when seeing through first filter layer 1 and a plurality of second filter layer 3, the edge can be collected with the dust to the conical terminal surface to guarantee the permeability and the filtering quality in most region.

When necessary, the middle parts between the first filter layer 1 and the second filter layer 3 and the adjacent second filter layer 3 are respectively provided with a limiting cushion block 5, and the spacing between the limiting cushion blocks 5 can be ensured, and the other side also plays a supporting role.
