Is suitable for filtering chemical raw materials in the fine chemical industry.

Description

High-efficient filter core

Technical Field

The utility model relates to a filter. In particular to a high-efficiency filter element on a fine filter. Is suitable for filtering chemical raw materials in the fine chemical industry.

Background

At present, in the chemical industry, the fine filters for filtering chemical raw materials are all traditional fine filters. Such conventional fine filters comprise a cylindrical housing in a vertical arrangement. The lower extreme of cylindric shell has the back cover, and its upper end has the upper cover that can open and shut, and there is the backup pad the lower part of cylindric shell inner chamber, and the equipartition has the screw in the backup pad. And filter elements with the same number as the screw holes are arranged on the support plate. The filter element comprises a mesh cylinder. The net cylinder is formed by processing a single-layer wire mesh, two ends of the net cylinder are respectively provided with a sealing cover, and one sealing cover is provided with a central hole used as an outlet. The outside of the sealing cover with the central hole is provided with a short pipe, the outer circle of the short pipe is provided with threads, and the inner end of the short pipe is connected with the periphery of the central hole into a whole. During installation, the short pipe at one end of the filter element is screwed into the screw hole on the support plate. Because the net barrel is formed by processing a single-layer metal wire mesh, the filtering surface of the net barrel is only the area of the net barrel, and the filtering surface is smaller. The filtering effect of such a fine filter is poor due to the small filtering area.

SUMMERY OF THE UTILITY MODEL

The to-be-solved problem of the utility model is to provide a high-efficient filter core. The high-efficiency filter element has large filtering area and good filtering effect.

The utility model discloses the above-mentioned problem that solves is realized by following technical scheme:

by adopting the scheme, the method has the following advantages:

the utility model discloses a high-efficient filter core, including a net section of thick bamboo, net section of thick bamboo both ends all have the closing cap, have the centre bore that is used as the export on one of them closing cap, and its characteristics are: the inner framework and the outer framework are both net cylinders, and a space is arranged between the inner framework and the outer framework. The net barrels are positioned in the space. The net cylinder is a folding cylinder formed by folding a rectangular metal wire net along the length direction in an equal width mode and then connecting two ends of the folded metal wire net together, and the length of the folding cylinder is the same as that of the inner framework and the outer framework. The adjacent folding layers of the folding cylinder are provided with included angles.

The outside of the sealing cover with the central hole is provided with a short pipe, the outer circle of the short pipe is provided with threads, and the inner end of the short pipe is connected with the periphery of the central hole into a whole.

According to the scheme, the net barrel is a folded cylinder formed by folding a rectangular metal wire net along the length direction in an equal width mode and then connecting two ends of the folded cylinder, and the length of the folded cylinder is the same as that of the inner framework and the outer framework. The adjacent folding layers of the folding cylinder are provided with included angles. The filtering area is multiplied compared with the screen cylinder made of single-layer metal wire mesh in the background technology. The filtering area is large, so that the filtering effect of the filter is greatly improved.

Drawings

FIG. 1 is a schematic view of the high efficiency filter element of the present invention;

fig. 2 is an enlarged sectional view a-a of fig. 1.

Detailed Description

As shown in fig. 1 and 2, the high-efficiency filter element of the present invention comprises a net cylinder 6, an inner frame 3 and an outer frame 4. The inner framework 3 and the outer framework 4 are both net-shaped cylinders, a space is reserved between the inner framework and the outer framework, and the net cylinders 6 are located in the space. The net cylinder 6 is a folded cylinder formed by folding a rectangular wire mesh along the length direction in an equal width manner and welding two ends of the folded cylinder together, and the length of the folded cylinder is the same as that of the inner framework 3 or the outer framework. Wherein, an included angle is reserved between the adjacent folding layers of the folding cylinder.

The two ends of the net cylinder 6, the inner framework 3 and the outer framework 4 are all welded with a shared sealing cover 5, and a central hole 2 used as an outlet is processed on one sealing cover 5. The outside of the sealing cover 5 with the central hole 2 is provided with a short pipe 1, the outer circle of the short pipe 1 is processed with screw threads, and the inner end of the short pipe is welded with the periphery of the central hole 2.
