Description

The mist of oil filter

Technical field

The utility model relates to a kind of mist of oil filter, is meant especially to see through space structure design, with the mist of oil filter of effective filtration and concentrated greasy dirt.

Background technology

As shown in Figure 1; The combination sectional structure that shows the mist of oil filter of existing patent No. M369176; This mist of oil filter mainly is when being used for the collection kit machine and carrying out cut; The a large amount of mist of oils that cause cutting oil vaporization to be produced because of cutting high temperature, like figure, this mist of oil filter 10 mainly has a casing 11 and supplies the suction mist of oils tentatively to filter and a cartridge filter 12 carries out the makers-up of end-filtration institute.

These casing 11 inside are formed with one first filter space 111, a suction space 112 and one second filter space 113 that is connected; And offer an inlet 114 and one outlet 115 of fuel feeding mist turnover in this first, second filter space 111,113; Wherein, 112 of this suction space are provided with an extraction sector 13 and supply the suction mist of oil; And this first filter space 111 is provided with one first filtration group 14 with these suction space 112 places of connection, and this second filter space 113 exports 115 places in this and is provided with one second filtration group 15, and this cartridge filter 12 has a pipe fitting 121 and is communicated with 11 outlets 115 of this casing; Make this this extraction sector 13 of mist of oil filter 10 mats; Mist of oil 114 is absorbed and is that this first filtration group 14 filters from entering the mouth, and making mist of oil after once filtering get into second filter space 113 through suction space is that the second filtration group 15 is filtered, and sees through pipe fitting 121 at last and gets into cartridge filters 12 and filter the back and discharge.

Aforementioned mist of oil filter 10 has three road filters, seems effectively mist of oil to be filtered the back discharge, and so arrangement of its interior spatial structure but can cause following point on the contrary when reality is used:

1, this first filtration group 14 is formed with an oblique web plate 141 towards inlet 114 places; The incline direction of this web plate 141 will be guided mist of oil and moved toward the below, space; Cause the first filtration group 14 effectively to utilize; Have only the real Filtration Adsorption greasy dirt of downside, not only filtering efficiency reduces, and the problem that cost increases of filtering is also arranged;

2, as shown in Figure 1; Mist of oil gets into cartridge filter 12 and filters preceding meeting at last earlier through the second filtration group 15, yet the position that is provided with of the second filtration group 15 is positioned at the minimum point that has mist of oil filter 10 now; Therefore; The inner greasy dirt of suction space 112 and cartridge filter 12 pipe fittings 121 will be organized 15 positions toward second filtration because of centrifugal force and move being accumulate to when a certain amount of, shorten, filters problems such as cost increase the service life that its filtration yield caused and have to increase;

3, if the second filtration group 15 fails to change often, the second filtration group 15 that accumulates big gauging trowel used for plastering will cause mist of oil to filter congestion situations easily, make mist of oil can't get into cartridge filter 12 and do last filtration, cause the mist of oil filter effect bad on the contrary.

The utility model content

The technical problem that the utility model will solve provides a kind of mist of oil filter, and it mainly sees through the arrangement of the inner filter space structure of this device, and the flow direction of change mist of oil is used the purpose that reaches effective lifting mist of oil filter filtering efficiency.

For solving the problems of the technologies described above, the mist of oil filter that the utility model provided comprises: a casing; Be formed with a base and a top shell; Said base is arranged with and is configured as an oil-collecting space, and shell inside, said top is formed with a filter space and a suction space, and the direction that definition provides said filter space and said suction space is one axial; Said filter space is formed with a relative air inlet and said casing external communications in said on axially; And one bleeding point be communicated with said suction space, the corresponding said bleeding point of said suction space place is formed with one group and establishes mouth, and said suction space bottom is formed with the oil-collecting spatial communication of an exhaust outlet and said base; One clamshell is configured as hollow structure, and is formed with an inlet and the outlet with the oil-collecting spatial communication of said casing in both sides, the end, top, and the corresponding said casing group of said clamshell establishes a mouthful place, axially is formed with a socket at a distance from establishing in said; One filter element, shell air inlet arc is convexly equipped with and puts towards said top to have the spoiler that is configured as circular shape, makes one first filter screen and one second filter screen be located between said spoiler and the said top shell bleeding point; One exhausting unit has a wind wheel and is located in the said casing suction space, and a motor is placed in the said clamshell socket, said wind wheel and said motor winding and be its driven in rotation; One cartridge filter, inner hollow and its barrel are formed with an inner filtering layer and an out filtering layer, and said cartridge filter has two ends, wherein end sealing, other end is configured as an opening and is connected with said clamshell outlet;

By this, the mist of oil filter of the utility model is from said casing air inlet suction mist of oil, makes that said mist of oil is that said filter element filters; And behind said suction space, said oil-collecting space and said clamshell inside; Discharge for the inside and outside filtering layer filtration of said cartridge filter, the utility model sees through cartridge filter is located on the clamshell, to change the flow direction of mist of oil; The whole filtering efficiency of not only effective lifting device has the advantage of simplifying the mist of oil filter simultaneously.

Relevant for the utility model for reaching above-mentioned purpose, the technology that is adopted, means and other effects, lift a preferred embodiment now and cooperate graphic detailed description as after.
