Abstract

The utility model discloses a spiral skeleton filter core, bend including the spiral and make the spiral skeleton that forms and enclose and locate the outer compound filter screen of spiral skeleton, compound filter screen has the spraying plastics protecting wire net including the glass fiber filter layer at center inside and outside the lining respectively of glass fiber filter layer the both ends of spiral skeleton still are equipped with upper and lower end cover respectively, upper and lower end cover respectively through the binder with spiral skeleton and compound filter screen bond fixedly. The utility model discloses a spiral skeleton filter core production processes simplifies, and material cost is low, has higher structural strength, and the pressure that the spiral skeleton of selecting equal thickness can bear is more than the tabulare frame that punches a hole, and the compound filter screen that glass fiber filter layer and inside and outside spraying plastics protecting wire net were made in the middle of adopting has higher wear -resisting and corrosion resistance for each side such as the performance of filter, life, use cost have all had great improvement, have overcome the problem that prior art exists.

Description

A kind of spiral skeleton filter element

Technical field

This utility model belongs to filter plant technical field, specifically relates to a kind of spiral skeleton filter element.

Background technology

The internal coiling skeleton of existing filter element is mostly to be welded with punching coiled sheet circle, skeleton in view of punching coiled sheet circle manufactures complex procedures, the bad control of circularity in volume circle, welding also can make aperture discontinuity, the most thick and heavy punched-plate must be selected to do skeleton and just can bear certain pressure, causing material cost higher, domestic consumer is difficult to accept.

Utility model content

The purpose of this utility model is: provide a kind of spiral skeleton filter element with low cost.

The technical solution adopted in the utility model is as follows: a kind of spiral skeleton filter element, the spiral skeleton that bends including spiral and enclose the composite screen being located at outside spiral skeleton, described composite screen includes the glass fiber filters at center, it is respectively lined with plastic-blasting protecting wire net glass fiber filters is inside and outside, further respectively have upper and lower end cap at the two ends of described spiral skeleton, described upper and lower end cap is adhesively fixed with described spiral skeleton and composite screen by binding agent respectively.

Spiral skeleton filter element of the present utility model uses the spiral skeleton bent, production process simplifies, the cost of material is low, skeleton circularity can be well controlled, and there is higher structural strength, select the pressure that the spiral skeleton of condition of equivalent thickness can be born much larger than punched-plate skeleton, the filter screen of the composite construction that employing intermediate glass fibrous filter layer and inside and outside plastic-blasting protecting wire net are made has higher wear-resisting and corrosion resistance, the everyways such as the serviceability of filter, service life, use cost are enhanced, overcome the problem that prior art exists.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model spiral skeleton filter element.

Detailed description of the invention

Below in conjunction with the accompanying drawings specific embodiment of the utility model is elaborated.

The specific embodiment of spiral skeleton filter element of the present utility model is as shown in Figure 1, it includes the spiral skeleton 1 that spiral bends, it is provided with composite screen in spiral skeleton 1 periphery, this composite screen includes the glass fiber filters 2 at center, it is lined with internal plastic spraying protecting wire net 3 in the inner side of glass fiber filters 21, is lined with outer plastic-blasting protecting wire net 4 in the outside of glass fiber filters 2.In a particular application, inside and outside plastic-blasting protecting wire net 3,4 is directly sprayed for the surfaces externally and internally at glass fiber filters 2 by workmanship of spraying plastics respectively.Further respectively have upper end cover 5 and bottom end cover 6 at the two ends of spiral skeleton 1, upper and lower end cap 5,6 is adhesively fixed with spiral skeleton 1 and composite screen by binding agent 7 respectively.

This utility model uses the spiral skeleton bent, production process simplifies, the cost of material is low, skeleton circularity can be well controlled, and there is higher structural strength, select the pressure that the spiral skeleton of condition of equivalent thickness can be born much larger than punched-plate skeleton, the filter screen of the composite construction that employing intermediate glass fibrous filter layer and inside and outside plastic-blasting protecting wire net are made has higher wear-resisting and corrosion resistance, the everyways such as the serviceability of filter, service life, use cost are enhanced, overcome the problem that prior art exists.

Claims (1)

1. a spiral skeleton filter element, it is characterized in that, including the spiral skeleton bent and enclose the composite screen being located at outside spiral skeleton, described composite screen includes the glass fiber filters at center, plastic-blasting protecting wire net is had in the inside and outside spray attachment respectively of glass fiber filters, further respectively have upper and lower end cap at the two ends of described spiral skeleton, described upper and lower end cap is adhesively fixed with described spiral skeleton and composite screen by binding agent respectively.
