Abstract
The invention discloses a improve invention of filter cleaner, includes end plate(2),filter paper web(4),center tube(3), the filter paper web suit on the out of cent tube, end plate set on the terminal of filter paper web and center tube. Its feature is that the material of end plate is tabulate plastic sheet, the end plate with filter paper web and center tube is burn connected. Without increasing filter size specifications of the filter element. The invention solved increasing filter size, extend life, reduce weight, filter manufacturing methods more convenient, while follow-up treatment in a more favorable environmental protection.
Description
[technical field]
The present invention relates to a kind of filter element that filters machine oil or impurity in fuel.
[background technology]
Cleaner is a kind of purifier that filters machine oil or impurity in fuel, is widely used in various pipe-line system.The core component of cleaner is a filter core, the flow resistance of cleaner and service life are directly by the decision of filter core performance quality, traditional filter core is made up of parts such as end cap, filtration paper cylinder, central tube up and down, wherein the filtration paper cylinder filter area how much determined very important performances such as cleaner life-span and flow resistance, central tube works to support filtration paper cylinder, increases filer element strength.Traditional filter core is with binding agent iron end cap and filtration paper cylinder to be bondd, and filter core need pass through operations such as injecting glue, bonding, curing, and technology is loaded down with trivial details.Former iron end cap shape is open cylindrical, its stile is high five millimeters, two end cap stiles are with regard to high ten millimeters up and down, filtration paper cylinder just wastes ten millimeters effective filtration area like this, former iron end cap adding additives makes the overall weight of the filter core comparison heaviness that seems, and is unfavorable for environmental protection during waste disposal.
[summary of the invention]
Problem in view of present known technology existence, the technical problem to be solved in the present invention just provides a kind of under the situation that does not increase the filter element dimensions, increase filter area, thereby increase flow, reduce resistance, the filter element that increases the service life, and make that the filter core, manufacturing method is more easy, weight reduction and environmental.
For solving the problems of the technologies described above, the present invention takes following technical scheme to realize: this kind filter element, comprise end cap, filtration paper cylinder, central tube, described filtration paper cylinder is sleeved on outside the central tube, end cap is arranged on filtration paper cylinder and central tube two ends, it is characterized in that: the material of described end cap is the plate type plastic thin plate, and described end cap and filtration paper cylinder and central tube scald knot and form.
The outside end face of described upper and lower end cap is bonded with a sealing ring respectively.
Because end cap has adopted flat thin plate up and down, thickness is about 0.5mm, and traditional iron end cap is open cylindrical, the high 5mm of its stile, two end cap stiles are with regard to high 10mm up and down, and two flat thin plate end cap height are 1mm, so two end cap just differs 9mm up and down.The effective filtration area of filtration paper cylinder has just increased 9mm like this, thereby makes filter core under the situation that does not increase dimensions, increases filter area, thereby increases flow, reduction resistance, increases the service life.The outside end face of upper and lower end cap is bonded with a sealing ring respectively, good seal when the assurance filter core is connected with other parts.
Because the material of upper and lower end cap is plastics, filter core directly scalds the cooling of knot back by upper and lower end cap heat fused and filtration paper cylinder, central tube and forms.Like this three process such as original injecting glue, bonding, curing and the more easy together operation of one-tenth, both simplified technology, saved binding agent again, iron end cap had been become plastic end cover, so alleviated weight, the weight of whole filter core only is original 1/3rd.When waste disposal, do not need to worry, help environmental protection for the processing once more of iron end cap.
[description of drawings]
The present invention has following accompanying drawing:
Fig. 1 is that the structure of filter core of the present invention is schemed naturally.
[specific embodiment]
With reference to Fig. 1, this filter element comprises two end cap 2, filtration paper cylinder 4, central tube 3 up and down, and the outside end face of upper/lower terminal lid 2 is bonded with a sealing ring 1 respectively.The material of end cap 2 is the plate type plastic thin plate.At first with the filtration paper cylinder press forming, with high temperature upper and lower two end caps 2 are heated simultaneously again, when treating 2 fusings of two end caps, promptly filtration paper cylinder 4 and central tube 3 are inserted into two end caps 2 of fusing, two end cap 2 two ends pressurizations and after pressurize a period of time, behind upper and lower two end cap cooling curings, just can take out product.
Claims (2)
1. filter element, comprise end cap (2), filtration paper cylinder (4), central tube (3), described filtration paper cylinder (4) is sleeved on outside the central tube (3), end cap is arranged on filtration paper cylinder and central tube two ends, the material that it is characterized in that described end cap (2) is the plate type plastic thin plate, and described end cap (2) scalds knot with filtration paper cylinder (4) and central tube (3) and forms.
2. a kind of filter element as claimed in claim 1 is characterized in that the outside end face of described end cap (2) is bonded with a sealing ring (1) respectively.
