Description

A kind of Cotton Gossypii filter element for cleaner

Technical field

This utility model is related to a kind of filter element, specially a kind of Cotton Gossypii filter element for cleaner.

Background technology

The impurity that machine oil is constantly fallen into by the microgranule of engine scuffing and the external world pollutes, and meanwhile, machine oil is produced by thermal oxide Life dissolves in the acidic materials of machine oil and soluble gelatinous precipitate.Solid particles in these impurity can increase the mill of electromotor Damage, gelatinous precipitate can make to occur between the parts such as piston and rings, valve and valve guide bushing cementing.The effect of cleaner is The above-mentioned objectionable impurities being present in machine oil being filtered the cleaning it is ensured that lubricating oil, thus protecting electromotor, extending its use Life-span, so, the important role of cleaner.Existing cleaner goes the function of deimpurity function mainly to be come by filter element Become, because filter element uses papery filter paper to hinder the impurity in filter oil, it is located between oil-in and oil-out, filters Precision be 30 μm～80 μm, filtering accuracy is low, leads to early stage abrasive wear, simultaneously easily block filter paper, produce filter cake effect, Thus shortening the service life of filter element.

For solving the above problems, therefore it is proposed that a kind of Cotton Gossypii filter element for cleaner.

Utility model content

The technical problems to be solved in the utility model is the defect overcoming prior art, provides a kind of cotton for cleaner Flower filter element.

In order to solve above-mentioned technical problem, this utility model provides following technical scheme：

A kind of Cotton Gossypii filter element for cleaner of this utility model, including central canal, filter paper and Cotton Gossypii, described filter paper around in Heart pipe bag one encloses, and described Cotton Gossypii is filled in outside filter paper, and upper and lower two end faces of described central canal are vertical with upper end cover, bottom end cover respectively Connect and intersection is provided with sealing ring, described upper end cover is connected with suspension ring handle, in described suspension ring handle and upper end cover horizontal plane Two suspension ring bases on heart axle are flexibly connected, and described upper end cover is identical with bottom end cover size and is separately fixed at and outer protects the two of bucket End, described outer shield bucket inwall is close to circle non-woven fabrics, and described non-woven wraps are in Cotton Gossypii outer layer.

Further, described central canal is hollow cylinder and uses bright tinplate material, described center pipe internal surface is equal The circular punching of even densely covered diameter 3cm.

Further, described suspension ring handle uses the zinc-coated wire of diameter 0.3cm.

Further, described sealing ring uses nitrile rubber material, cross section be in inverted trapezoidal and hypotenuse cave inward and with The packing ring enclosing projection in upper end cover is meshed, and described sealing ring inwall is inwardly projecting to form two row's semicircular ring.

Further, the interlock spacing of the through hole and axial two through hole opening up diameter 2cm of described outer shield bucket surface is 21cm, Described outer shield bucket upper and lower ends stretch out and form an arc back-up ring, and described outer shield bucket bucket wall joint adopts double-hasp riveting Close.

The beneficial effect that this utility model is reached is：Bright tinplate material is resistance to by the intensity of steel and mouldability and stannum Corrosion, tin-welding and pleasing aesthetic appearance are incorporated in a kind of material, no impression, no scratch, no significantly wedge angle burr, there is corrosion resistant Corrosion, the feature that nontoxic, intensity is high, ductility is good, in addition the outer double-hasp riveted construction protecting bucket, is led by engaged formation Power processed, solves the problems, such as that long-time immersion and machine oil enter fashionable pressure and is easily deformed, extends the service life of filter element, Cotton Gossypii With cooperating of filter paper, increase filter area, improve filtering accuracy and do not result in early stage abrasive wear and filter paper blocking simultaneously, Increase the safety of filter element.
