According to the environment-friendly filter element, the connection between the upper end cover and the paper element, and the connection between the lower end cover and the paper element are firmer, the filter element is more environment-friendly, the processing technology is simplified, and the processing efficiency is high.
Description
Technical field
The present invention relates to a kind of environmental-protective filter, be specifically related to a kind of filter element of environmental protection.
Background technique
Traditional filter element is mainly comprised of upper end cap, lower end cap, filter paper, center tube etc., and being connected by hot-setting adhesive between product end cap and filter paper is heating and curing or two component glue has solidified.In existing this type of product technology, being connected of end cap and refill adopts hot-setting adhesive drying tunnel mode of heating to complete, and the product that this kind of mode made exists following problem:
1, the difficult control effect performance of injecting glue amount and outward appearance: in end cap injecting glue quantity not sufficient easily cause refill and end cap bonding insecure or do not have bonding, actual using process formation " short circuit " phenomenon; Injecting glue amount is too many in end cap, puts into end cap and can make glue overflow end cap to flow to the places such as refill, thereby cause refill outward appearance to pollute or operation element platform pollutes and affects other semi-finished product when refill.
2, refill perpendicularity is difficult controls: because injecting glue process refill is put into end cap and is controlled its perpendicularity without other assistant tool, when previous process paper folding occur a little deviation or this process operations not in place, just there is crooked phenomenon in the product of making.
3, energy consumption is large: injecting glue cured article adopts drying tunnel heating mode, and drying tunnel power consumption is large.
4, conflict with filter paper solidifying and setting effect: during filter paper paper folding, need be heating and curing and could formalize, injecting glue product hot-setting adhesive drying tunnel heating-up temperature is at 160-190 degree, and the time needs 15-20 minute, and some filter paper can cause over cure because of regelate.
5, labour force aspect: this kind of explained hereafter, solidify respectively at bonding two that more than 90% adopts of two end cap and refill, and manufacturing efficiency is not high; And employee needs 5 people, and average product is low.
6, in use applying glue difficulty of two component glues is large, and equipment investment cost is high, and operation easier is large.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of environmental-protective filter filter core, is connected more firmly between the upper and lower end cap of filter core and filter paper, and filter core is environmental protection more, and processing technology is simplified simultaneously, work efficiency is high.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: a kind of environmental-protective filter filter core, comprise the refill between upper end cap, lower end cap and upper end cap and lower end cap, between described upper end cap and refill, all bond by nitrile butadiene rubber film between described lower end cap and refill.
Adhesive material is nitrile butadiene rubber film, add man-hour, after with the thin nitrile butadiene rubber film of the thick ring of 1.2-1.4mm, through foaming machine, heating is pressurizeed, upper end cap and lower end cap link together with refill by nitrile butadiene rubber film foaming sulfuration, glue-line after nitrile butadiene rubber film solidifies has good water-fast, oil resistant, heatproof, ageing-resistant performance, the aging of resistance to machine oil (150 ℃ * 192h) does not come unstuck, and after finishing working life, be easy to process, be a kind of novel environmental protection and energy saving filter core, product cost reduces.
As preferably, described upper end cap comprises end cap body and is located at the through hole on end cap body, described through hole is circular hole, described end cap body is provided with boss, described end cap body and boss are structure as a whole, described through hole runs through end cap body and boss, described boss can elastic recovery when along axially the pressing of through hole elasticity boss, described boss is the cylindrical body of hollow, described boss is provided with snap ring, described snap ring internal diameter is less than the internal diameter that boss is positioned at place, two ends, and described snap ring external diameter is less than the external diameter that boss is positioned at place, two ends.As preferably, described upper end cap comprises end cap body and is located at the through hole on end cap body, described through hole is circular hole, described end cap body is provided with boss, described end cap body and boss are structure as a whole, described through hole runs through end cap body and boss, described boss can elastic recovery when along axially the pressing of through hole elasticity boss, described boss is the cylindrical body of hollow, described boss is provided with snap ring, described snap ring internal diameter is less than the internal diameter that boss is positioned at place, two ends, and described snap ring external diameter is less than the external diameter that boss is positioned at place, two ends.Boss is flexible, coordinates closely while installing with assembly, has the function of similar seal ring, can play good seal action, and boss indent, forms a snap ring, and simply, good seal performance, has certain elasticity while making boss along axially the pressing of through hole in assembling.
As preferably, described lower end cap comprises end cap body and is located at the through hole on end cap body, described through hole is circular hole, described end cap body is provided with boss, described end cap body and boss are structure as a whole, described through hole runs through end cap body and boss, described boss can elastic recovery when along axially the pressing of through hole elasticity boss, described boss is the cylindrical body of hollow, described boss is provided with snap ring, described snap ring internal diameter is less than the internal diameter that boss is positioned at place, two ends, and described snap ring external diameter is less than the external diameter that boss is positioned at place, two ends.As preferably, described upper end cap comprises end cap body and is located at the through hole on end cap body, described through hole is circular hole, described end cap body is provided with boss, described end cap body and boss are structure as a whole, described through hole runs through end cap body and boss, described boss can elastic recovery when along axially the pressing of through hole elasticity boss, described boss is the cylindrical body of hollow, described boss is provided with snap ring, described snap ring internal diameter is less than the internal diameter that boss is positioned at place, two ends, and described snap ring external diameter is less than the external diameter that boss is positioned at place, two ends.
Beneficial effect:
A kind of environmental-protective filter filter core that the present invention adopts technique scheme to provide, adhesive material makes nitrile butadiene rubber film into by hot-setting adhesive or two component glue, upper end cap and lower end cap are vulcanized with refill and are linked together by foamable, bonding even, firm, without short-circuit conditions, occur, avoided use glue to have injecting glue amount problem rambunctious, avoided using glue exist injecting glue amount inhomogeneous cause bonding insecure or there is no a bonding phenomenon; Glue-line after nitrile butadiene rubber film solidifies has good water-fast, oil resistant, heatproof, ageing-resistant performance, the aging of resistance to machine oil (150 ℃ * 192h) does not come unstuck, and after this kind of product finishes working life, being easy to process, is a kind of novel environmental protection and energy saving filter core, and product cost reduces.
