Abstract

The utility model relates to a filter for machine oil. The filter for machine oil is made into a flat box shape by an outer cover and a base by a hinge. A magnet, an iron block, a spring, and a spongy filtering body are arranged inside the filter for machine oil. A plurality of oil inlet holes and oil outlet holes are arranged on the upper surface and the circumference of the exterior of the filter for machine oil. The filter for machine oil is arranged at the bottom of an oil box. The filter for machine oil is made to generate excitation by the inherent vibration of a machine. The filter for machine oil can continuously generate the functions of slight opening and closing accompanied with excitation under the double action of the ferromagnetic attraction force of the interior and the elasticity of the spring, and machine oil continuously enters and discharges the filter for machine oil to circulate. The magnet and the spongy filtering body in the filter for machine oil can adsorb and collect the iron dust powder and other impurities which are contained in the machine oil, and thereby, the purpose of filtering the machine oil is achieved. The utility model has the advantages of simple and light structure, very convenient use, low manufacturing cost, and good filtering effect.

Description

Filter for machine oil

The utility model relates to a kind of oil filter, is specially adapted to the iron filings powder impurity in the filtering machine oil.

The many more complicated of existing oil filter structure, its installation site places the sump outside more, and the machine oil in the running machine, main component is the iron filings powder impurity that machine zero, component wear produce in its impurity, quality is heavier, be deposited on oil-tank bottom, therefore the filtering effect of existing machine filter is desirable not enough more.

It is a kind of simple in structure light and handy that the utility model provides, and places oil-tank bottom, based on the oil filter of the iron filings powder impurity in the filtering machine oil.

Technical solution of the present utility model mainly is made of with spring ［ 2 ］, iron block ［ 3 ］, filter body ［ 4 ］, magnet ［ 9 ］ enclosing cover ［ 1 ］, base ［ 7 ］, enclosing cover ［ 1 ］ and base ［ 7 ］ are with the slight flat box shaped body of opening and closing of one of the hinged formation of hinge ［ 6 ］, box body is built-in with spring ［ 2 ］, iron block ［ 3 ］, filter body ［ 4 ］, magnet ［ 9 ］, spring ［ 2 ］ for compressing spring, one end props up on enclosing cover ［ 1 ］, and the other end props up on ［ 7 ］ at the bottom of the seat; Iron block ［ 3 ］ is installed on the enclosing cover ［ 1 ］, magnet ［ 9 ］, is installed on the base ［ 7 ］, and both toward each other and keep the certain interval distance; Filling filter body ［ 4 ］ in the box body inner space, filter body ［ 4 ］ is every cotton many micropores of shape shape mollielast; Around box body top reaches, on enclosing cover ［ 1 ］ and base ［ 7 ］, have oilhole ［ 8 ］, referring to accompanying drawing 1,2.

Specific embodiment of the utility model is that enclosing cover ［ 1 ］ is all made the dome shape with sheet metal with base ［ 7 ］, with oblate box-like body of the hinged formation of hinge ［ 6 ］, its inside is fixed with cylindrical iron block ［ 3 ］ on enclosing cover ［ 1 ］, on base ［ 7 ］, be fixed with cylindrical permanent magnet ［ 9 ］, iron block be contained in the corresponding position of magnet ［ 9 ］ on, parallel to each other, the clearance distance of spaced apart 2mm, be supported with compression spring ［ 2 ］ between enclosing cover ［ 1 ］ and base ［ 7 ］, spring ［ 2 ］ one ends prop up on enclosing cover ［ 1 ］, and the other end props up on base ［ 9 ］.Space in the box is filled filter body ［ 4 ］ and is made with the flexible foam plastic Sponge, around reaching, the circular surfaces of outer box ［ 1 ］ has the oilhole ［ 8 ］ of some small sircle holes on the wall and on the wall all around of base ［ 7 ］ as turnover oil, horizontal setting has filter screen ［ 5 ］ in box body, and filter screen ［ 5 ］ is a steel wire.When oil filter of the present utility model places sump, because the vibration during machine run, make oil filter produce exciting with it, when the magnet of oil filter inside ［ 9 ］ and iron block ［ 3 ］ produce suction and make enclosing cover ［ 1 ］ with base ［ 7 ］ and closed, when the elastic force of compression spring ［ 2 ］ then makes enclosing cover ［ 1 ］ and base ［ 7 ］ and open, thisly be accompanied by opening that exciting produces, cooperation is used, make machine oil constantly in cleaner, pass in and out circulation, metallic iron break flour contained in the machine oil is sunk collection in cleaner by magnet ［ 9 ］ absorption, other impurity are also by filter body ［ 4 ］ absorption, can take out cleaner every a period of time and clean, thus the cleaning in the assurance machine oil.

The utility model has the advantage of simple in structure lightly, use very conveniently, cheap that filtering is effective.
