Abstract
The utility model provides a compound filter paper of fuel, belong to filter paper technical field, including fuel filter paper layer, polypropylene membrane filter paper layer, fuel filter paper layer bonds together with the mode that polypropylene membrane filter paper layer passes through ultrasonic bonding, the pit that has align to grid is pressed to polypropylene membrane filter paper layer one side of compound filter paper of fuel through rolled form, the diameter of pit is 2mm-3mm, the pit degree of depth is 1mm-1.8mm, this complex filter paper has improved oil strain efficiency, especially, be fit for europe no. 3, the machineshop car that ou si discharged uses.
Description
Technical field:
The utility model relates to cleaner accessory technical field, specifically relates to a kind of fuel oil composite filter paper.
Background technology:
Filter paper is a kind of paper with good strainability, and papery is loosened, and has strong absorbent properties to liquid.Assay laboratory commonly uses filter paper as filter medium, solution is separated with solid, filter paper is mainly used in the places such as greasy dirt filtration, air filtration, oil-water separation filter paper is mainly used on the fuel filter of the heavy construction car of Europe three and Ou Si discharge standard, load wagon, mainly oil product is filtered, ensure the clean of oil product, filter paper conventional is at present the filter paper of single-part stationery material, and this filter paper also exists the defect that filtering accuracy is lower, service life is shorter.
Summary of the invention:
The utility model papery filter paper in existing technology also exists a kind of fuel oil composite filter paper that filtering accuracy is low, service life is shorter and provide, thus solves deficiency of the prior art.
The utility model solves the scheme that its technical problem adopts: as shown in Figure 1, a kind of fuel oil composite filter paper, comprises fuel filter ply of paper, polypropylene screen filter paper layer, and fuel filter ply of paper and polypropylene screen filter paper layer are bonded together by the mode of ultrasonic bonding.
The polypropylene screen filter paper layer side of fuel oil composite filter paper is pressed with evenly distributed pit by the form of roll extrusion, and the diameter of pit is 2mm ~ 3mm, and pit depth is 1mm ~ 1.8mm.
The utility model passes through technique scheme, there is following effect: a kind of fuel oil composite filter paper, it adopts the form of ultrasonic bonding, by fuel oil filter paper and polypropylene screen filter paper welded together, improve oil strain efficiency, be especially applicable to the engineering truck use of Europe three, Ou Si discharge.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
In figure: 1, polypropylene screen filter paper layer; 2, fuel filter ply of paper 101, pit
Detailed description of the invention
Below in conjunction with accompanying drawing shownschematically most preferred embodiment be described in further detail the utility model and solve the scheme that its technical problem adopts and be: as shown in Figure 1, a kind of fuel oil composite filter paper, comprise fuel filter ply of paper 2, polypropylene screen filter paper layer 1, fuel filter ply of paper 2 and polypropylene screen filter paper layer 1 are bonded together by the mode of ultrasonic bonding.
Polypropylene screen filter paper layer 1 side of fuel oil composite filter paper is pressed with evenly distributed pit 101 by the form of roll extrusion, and the diameter of pit 101 is 2mm ~ 3mm, and pit 101 degree of depth is 1mm ~ 1.8mm.
Described fuel oil composite filter paper, when it is implemented, at device for ultrasonic welding, fuel filter paper bowl, polypropylene screen filter paper roller are installed, start device for ultrasonic welding, after two kinds of filter paper pass through under ultrasonic bonding head, because hyperacoustic vibration at high speed effect makes two kinds of filter paper be bonded together, namely fuel oil composite filter paper is defined, afterwards by the rolling shaft of band projection, the roll extrusion of this filter paper namely can be obtained being with the composite filter paper of pit 101, this filter paper has possessed long-life that two kinds of independent filter paper do not have, filtration efficiency.
Claims (2)
1. a fuel oil composite filter paper, feature comprises fuel filter ply of paper, polypropylene screen filter paper layer, and fuel filter ply of paper and polypropylene screen filter paper layer are bonded together by the mode of ultrasonic bonding.
2. a kind of fuel oil composite filter paper according to claim 1, is characterized in that: the polypropylene screen filter paper layer side of fuel oil composite filter paper is pressed with evenly distributed pit by the form of roll extrusion, and the diameter of pit is 2mm ~ 3mm, and pit depth is 1mm ~ 1.8mm.
