Abstract
The utility model relates to a gas filter element. The outer part of a cylinder frame-shaped support structure unit is wound with a filter medium structure layer, the axial center of the cylinder frame-shaped support structure unit is provided with an air flow channel, and the perisporium is provided with a ventilation structure. Both axial ends are respectively connected with an annular end plate member, wherein, the filter medium structure layer is wound outside the cylinder frame-shaped support structure unit in a backfolding wave form.
Description
The utility model relates to a kind of gas filter element that is used for gas purifying equipment.
The filter element that uses in the existing gas purifying equipment all is columniform basically, is that gas channel and perisporium have wrapping outside the cylindrical tube shelf supporting construction unit of ventilation device that the form of filter media material is arranged in axial centre promptly.The shortcoming of this structure is that its filter area is subjected to the diameter of this supporting construction unit and the restriction of length.Its diameter and length are once determining, the effective filtration area of this filter element is a determined value, as increasing filter area, can only increase the number of filter element, or the size of increasing filter, thereby cause the increase of weight of equipment and the increase of manufacturing cost inevitably.
Given this, the purpose of this utility model is for cylinder shape filtering element filter area in the solution above-mentioned gas cleaning equipment is subjected to the problem of tube core support unit diameter restrictions, and a kind of gas filter element that can significantly improve the new structure of effective filtration area is provided.
Gas filter element of the present utility model is that gas channel and perisporium have outside the tube shelf supporting construction unit of ventilation device and be surrounded with the filter media construction layer in axial centre, and its axial two ends also are connected with the looped end board member respectively.Wherein said filter media construction layer is for to surround outside the said tube shelf supporting construction unit with the wave form of turning back.
The said waveform configuration of turning back that surrounds the filter media construction layer outside the tube shelf supporting construction unit with the wave form of turning back can have various ways in the said structure, for example, can make this surround filter media construction layer outside the tube shelf supporting construction unit for its return portion bit line is the form of the straight line parallel with the axial direction of filter element, also can make its return portion bit line be different forms such as, oblique vertical or spiral with the axial direction of filter element with the wave form of turning back.Wherein to adopt the former, promptly the return portion bit line of its waveform configuration form of straight lines parallel with axial direction is for well.Thisly the filter media construction layer is become with the wave form of turning back surround version outside the said tube shelf supporting construction unit, can make under the prerequisite that does not change central support structure element diameter size, can increase substantially the filter media construction layer and effectively filter area be self-evident.On this architecture basics, the mode of filtration layer that can also be by changing the proper area size further reaches and makes the effective filtration area can be according to filtering the purpose that needs or hope are regulated.
On the basis of said structure, for ease of the setting of filter media construction layer with hold, can adopt and make said filter media construction layer is to be connected with the wave form of turning back to surround the form on the passage filtering layer supporting structure of having outside the said tube shelf supporting construction unit.
For the above-mentioned filter element of difference use field and/or application target, the structure of said filter media construction layer can be different.As, can adopt make this filter media construction layer for interior protection stratum reticulare and outside the catch net interlayer be gripped with the version of filtering medium layer.The filtering medium layer that wherein inserts and puts can suitably be selected for use according to the character of filtering gas and/or by the granularity size of filtering material and adjust.
For example, the structure of above-mentioned a kind of filter media construction layer that can adopt is: interior protection stratum reticulare wherein and outer protection stratum reticulare are thick, middle steel mesh structure layer, and filtering medium layer is the fine filtering screen net structure.This filter media construction layer can be connected and fixed with the filtering layer supporting structure by the compressing structure spare through being combined with bolt, also can make itself and filtering layer supporting structure interconnect fixing by other suitable mode.
Interconnect vertically in use for ease of each filter element, but can on the basis of said structure, make the looped end board member at the axial two ends of said filter element have the location concaveconvex structure that the phase coadaptation cooperates respectively.Wherein so that the location concaveconvex structure on said this looped end board member is but that to have the version on the tapering inclined-plane that the phase coadaptation cooperates comparatively desirable.
Below by embodiment shown in the drawings foregoing of the present utility model is further described.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.All products of being realized based on the above-mentioned principle of the utility model all belong to scope of the present utility model.
Fig. 1 is the structural representation of the utility model gas filter element.
Fig. 2 is the end direction structural representation of Fig. 1.
Fig. 3 is the I portion partial structurtes schematic diagram of Fig. 2.
Fig. 4 is the II portion partial structurtes schematic diagram of Fig. 1.
In the gas filter element as shown in the figure, on having axial centre gas channel and perisporium, be placed with outside the circular tube shelf supporting construction unit 5 of passage, hold to be fixed with and have passage 11 filtering layer supporting structures 2 with the wave form of turning back repeatedly.This filtering layer supporting structure 2 is welded for holes folding steel plate V-shaped by section or W shape connects successively, and to make the return portion bit line of its V-arrangement or W shape and soldered wires be the form of straight lines parallel with the axial direction of element.The company's of wrapping formula is fixedly connected with the filter media construction layer outside this filtering layer supporting structure 2.This filter media construction layer for the interior protection stratum reticulare of making by thick, middle steel wire 6 and outside protect 8 of stratum reticulares to be gripped with the version of the filtering medium layer of making by the fine filtering silk screen 7.The press strip type member 9 of this filter media construction layer through being combined with bolt 10 interconnects fixing with filtering layer supporting structure 2.The radial structure profile of tooth as shown in Figure 2 or the form of cosmos of its outer filtration layer is fixed in filtering layer supporting structure 2 in this gas filter element and wrapping.Respectively be connected with a looped end board member 1,3 at the axial both ends of filter element, but its outboard end has the concavo-convex fixing structure 12 in location of 60 ° of tapering inclined-plane forms of phase coadaptation cooperation respectively.According to using needs, at the also configurable seal washer 4 that appropriate format is arranged in one end plate member place.
