Abstract

The invention discloses a filter cleaner filter core, including upper and lower cover(1, 1 '), filter paper web(2), the center tube(3), in filter paper web(2) Set in the out of center tube(3), characterized the described upper and lower cover(1,1 ') used epoxy material production, epoxy curing period after solidifying with center tube(3) and filter paper web(2) at the same time connected to the two ends of one. Instead of using epoxy Cover, binder, Seal, it has a simple structure, reduce weight, no longer need punch, bonding, curing and heating, as long as the resin into the mold, let it filter paper web and the center tube integration can be cured with natural, it significantly reduced processes and equipment, based on the same size filter specifications and performance, simplified streamline processing and product mix, reducing the weight of the product, without unglued phenomenon, reduced processing equipment.

Description

Filter element

[technical field]

The present invention relates to filter a kind of filter element of impurity in machine oil or the fuel oil, he can improve the corrosion resistance of filter core and service life, alleviate the weight of cleaner greatly.

[background technology]

At present, known filter element is made up of other parts such as upper and lower covers, binding agent, filtration paper cylinder, central tubes, operations such as and our traditional filter core is with binding agent iron end cap, filtration paper cylinder and central tube to be bondd, and then embeds a sealing ring at the endoporus of end cap, and filter core need pass through injecting glue, bond, be heating and curing, end cap needs operations such as punching press, technology is loaded down with trivial details, and use equipment is many, and structure is also complicated, and the binding agent adhesion strength is also bad, and degumming phenomenon is often arranged; Former iron end cap and binding agent make the overall weight of filter core seem heavier.And main engine plants require toward the light weight direction to develop, to save the weight of cost, reduction complete machine.

[summary of the invention]

Loaded down with trivial details in order to overcome the filter core processing technology, the filter element of characteristics such as complex structure, Heavy Weight, the shortcoming of easily coming unstuck the invention provides a kind ofly under the situation that does not reduce the various performances of filter core, reduce processing technology, and be simple in structure, in light weight, as not come unstuck.In order to achieve the above object, the technical scheme that technical solution problem of the present invention is adopted is: this kind filter element, include upper and lower covers, filtration paper cylinder, central tube, described filtration paper cylinder is sleeved on outside the central tube, it is characterized in that described upper and lower covers adopts epoxide resin material to make, the meeting while is connected as a single entity with the two ends of central tube and filtration paper cylinder behind the described epoxy resin cure.There is not degumming phenomenon in intensity height, corrosion-resistant behind the epoxy resin cure.Because epoxy resin intensity is good, can replace end cap to play a supportive role with it fully, good toughness, the roughness of epoxy resin are little simultaneously, can replace end cap seal to enclose sealing function with it.After adopting epoxy resin to replace end cap, binding agent, sealing ring, it is simple that structure becomes, weight saving, also no longer need punching press, bonding and be heating and curing, as long as resin is poured in the mould, allow it and filtration paper cylinder and central tube together spontaneous curing combine together and get final product, its operation and equipment significantly reduce.Also dispose in addition an annex sealing ring, so that when renew cartridge more, change original aging sealing ring.

The invention has the beneficial effects as follows that under same size specification and strainability, simplified processing process and product structure have alleviated product weight, no degumming phenomenon has reduced process equipment.

[description of drawings]

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is the longitudinal section of filter core;

Fig. 2 contains liquid resinous die drawing.

1. is epoxy resin end caps among the figure, 2. is filtration paper cylinders, 3. is central tubes, 4. is to contain liquid resinous mould.

[specific embodiment]

In Fig. 1, epoxy resin and curing agent are mixed, make the epoxy resin liquefy, liquid-state epoxy resin is poured in the mould 4 successively, after spending a few minutes, central tube 3 and filtration paper cylinder 2 are inserted in the liquid-state epoxy resin, the epoxy resin spontaneous curing formed epoxy resin up and down end cap 1,1 ', resin end cap 1,1 ' after combining together in the two ends of central tube 3 and filtration paper cylinder 2, in mould 4, filter core is extracted lightly, so just replaced end cap, binding agent and end cap seal circle with epoxy resin.An annex O RunddichtringO going along with in accessory bag in addition is so that when renew cartridge more, change the sealing ring on the assembly.

Claims (1)

1, a kind of filter element, include upper and lower covers (1,1`), filtration paper cylinder (2), central tube (3), described filtration paper cylinder (2) is sleeved on outside the central tube (3), it is characterized in that described upper and lower covers (1,1`) adopts epoxide resin material to make, can be simultaneously behind the described epoxy resin cure be connected as a single entity with the two ends of central tube (3) and filtration paper cylinder (2).
