Abstract
The invention discloses a filter core. The filter core comprises a filtration body, wherein the filtration body adopts a hollow structure, and a cavity is formed in the filtration body. An opening is also formed in the filtration body, and communicates with the cavity and the outer part of the filtration body. The filtration body is made of polyethene. A plurality of filtration mesopores for filtration are formed in the wall body of the filtration body. The filter core disclosed by the invention is simple in structure, is large in filter ventilation under high filtration accuracy, long in service life, simple in making technology and high in production efficiency.
Description
Technical field
The invention belongs to gas purification technique field, relate to a kind of filter core.
Background technology
The effect of filter core is by the dust-filtering in gas out, realizes Purge gas.At present, the structure of filter core of the prior art is generally by surrounding a columnar filter core for filtering after paper or non-woven fabrics fold.This filter core often comes with some shortcomings a little: 1, when filtering accuracy is higher, and ventilation can decline comparatively fast, thus causes ventilation to diminish, and cannot meet user demand; 2, paper or non-woven fabrics cracky, filter core is shorter for service life; 3, complex structure, manufacture craft is loaded down with trivial details, thus causes production efficiency low.
For this reason, a kind of filter core of necessary design, to solve the problem.
Summary of the invention
The object of this invention is to provide a kind of filter core, filtering accuracy is large compared with ventilation time high, and long service life and production efficiency high.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of filter core, comprises filtering bodies;
Described filtering bodies is hollow structure, is provided with cavity in it;
Described filtering bodies is also provided with opening, the outside of cavity and described filtering bodies described in this open communication;
The making material of described filtering bodies is polyethylene, and the wall body of this filtering bodies is provided with several filtration pores for filtering.
Further, the profile of described filtering bodies is cylindrical, and be provided with one in it in tubular cavity, one end of described filtering bodies or two ends are provided with described opening.
Further, the center line of described cavity overlaps with the center line of described filtering bodies.
Further, described opening is rounded, and this opening is corresponding with described cavity.
Beneficial effect of the present invention: filter core of the present invention, its structure is simple, and filtering bodies is be provided with several to filter the polythene material of pores, compared with filter core of the prior art, this filter core is under comparatively high filtering precision, the ventilation of filtering is also larger, and not fragile, long service life, adopts centrifugal molding process one-shot forming to be made simultaneously, therefore manufacture craft is simple, and production efficiency is high.Therefore, filter core of the present invention, when filtering accuracy is higher, ventilation is also large, and long service life and production efficiency high.

Detailed description of the invention
Below in conjunction with accompanying drawing of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1:
As shown in Figure 1 and Figure 2, the filter core of the present embodiment.This filter core comprises filtering bodies 1, and the profile of filtering bodies 1 is cylindrical, and this filtering bodies 1 is in hollow structure, and be processed with one in it in tubular cavity 11, wherein, the center line of cavity 11 overlaps with the center line of filtering bodies 1.One end of filtering bodies 1 or two ends are processed with circular opening 12, and this opening 12 is communicated with the outside of cavity 11 and filtering bodies 1, and opening 12 is corresponding with cavity 11.The making material of filtering bodies 1 is polyethylene, is made by centrifugal molding process, and the wall body of this filtering bodies 1 is provided with several filtration pores (accompanying drawing is not shown) for filtering.
Embodiment 2:
The structure of the filter core of this embodiment as shown in Figure 3.The filter core of this embodiment and the filter core of embodiment 1 unlike: the lower end of filtering bodies 1 is hermetically-sealed construction.
The operation principle of filter core of the present invention is: the gas be filtered enters the cavity 11 in filtering bodies 1 from opening 12, because the air pressure in cavity 11 is greater than the air pressure of filtering bodies 1 outside, therefore cavity 11 forms pressure reduction with filtering bodies 1 outside, gas in cavity 11 through the wall body of filtering bodies 1 filtration pore and flow to outside, the dust granules in gas is mixed in this process, cannot be filtered out by filtering pore because dust granules is comparatively large, thus achieve the function of Purge gas.
To sum up, filter core of the present invention, its structure is simple, and filtering bodies is be provided with the polythene material that several filter pore, compared with filter core of the prior art, this filter core is under comparatively high filtering precision, and the ventilation of filtration is also comparatively large, and not fragile, long service life, adopt centrifugal molding process one-shot forming to be made, therefore manufacture craft is simple, and production efficiency is high simultaneously.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
