Detailed description of the invention
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings, but
Not as to restriction of the present utility model.
Refer to Fig. 1 to Fig. 3, this utility model embodiment provides a kind of oil content barrel, including: bucket
Body, once oil point filter screen 3, exhaustor 5 and secondary oil divide filter screen 6.
Wherein, the sidewall of staving 1 offers air vent 2, in the radial direction of staving 1 in staving 1
Once oil point filter screen 3 it is provided with in plane, thus in the end of once oil point filter screen 3 with staving 1
Between form the first cavity 4.Exhaustor 5 is positioned at described staving 1, and described exhaustor 5
One end enters in described first cavity 4 through described once oil point filter screen 3, so, and exhaustor 5
The air-flow of output is introduced in the first cavity 4, the most again by once oil point filter screen 3, and secondary
Oil point filter screen 6 is then arranged at described air vent 2, thus to through once oil point filter screen 3 mistake
Air-flow after filter carries out secondary filter.
Visible, owing to have employed technique scheme, this utility model can be by once oil point filter
Air-flow is once filtered by net 3, when the air-flow after filtering is discharged through air vent 2, then
Secondary divided filter screen 6 to filter by secondary oil, then, improve oil point by above secondary filter
Efficiency so that the oily component efficiency of compressor self increases, and maintains the oil circulation stable of compressor,
Reduce unit to the load in terms of compressor oil return, there is the spy of simple in construction, low cost
Point.
In this utility model, owing to the filter effect of original once oil point filter screen 3 itself can
Reach more than 90 percent, although still small part oil can be mixed in coolant by once oil point filter
Net, but divide filter screen 6 owing to being provided with secondary oil at air vent 2, therefore discharging compressor
Before, secondary oil divides filter screen 6 the most accurately to filter, thus is truly realized inside compressor
Oil circulation is the most self-sufficient.
In the embodiment shown in Figure 2, it is preferable that can be by the first screw 7 by once oil
Filter screen 3 is divided to be arranged in described staving 1.It is further preferable that be internally formed solid at staving 1
Determining platform 8, fixed station 8 can be prominent to the inside of staving 1 along the radial direction of staving 1, so, once
Oil point filter screen 3 just can be fixed on fixed station 8 by the first screw 7.A preferred reality
Executing in example, be provided with multiple fixed station 8 in staving 1, these fixed stations 8 are arranged dispersedly, with
There is provided multiple fixing strong point to once oil point filter screen 3, thus improve the stability of installation,
And too much space will not be occupied, it is ensured that once oil point filter screen 3 has sufficiently large gas
Flow by area, thus ensure that the oily component efficiency of once oil point filter screen 3.
As shown in Figures 2 and 3, it is preferable that secondary oil in one embodiment divides filter screen 6
Can have cup-like structure, such as, this cup-like structure is at least by annular barrel 9, flange 10 and
The cylinder end 11, is constituted, and wherein, annular barrel 9 has two end faces, flange 10 and annular barrel 9
An end face edge connect, at the bottom of cylinder, 11 then by complete for another end face of annular barrel 9
All standing, but at the bottom of annular barrel 9 and cylinder 11, all offer multiple filtering holes 12.Pass through
This structure, not only can use the filtering holes 12 that aperture is finer and closely woven, and due to ring-type
It is respectively provided with filtering holes 12 on 11 at the bottom of cylinder 9 and cylinder, also ensure that the gross area of filtering holes 12,
Ensure that the handling capacity of air-flow.
These filtering holes 12 apertures are fine and closely woven, can effectively intercept passing through of oil droplet.But,
The crushing that a secondary oil divides filter screen 6 likely can increase aerofluxus both sides is increased at air vent 2,
And the pressure loss that secondary oil divides filter screen 6 to produce can be surveyed by the pressure of both sides layout in experimentation
Point carries out actual monitoring, if creating the pressure loss exceeding predefined size, then Ke Yitong
The mode crossing the bore increasing corresponding air vent 2 controls pressure at expulsion.
In the preferred embodiment shown in figure 2, secondary oil divides filter screen 6 can be pacified by the second screw
Installing to exhaust ports, wherein, the second screw is located in the installing hole of flange 10, and its screw thread is certainly
It is connected with the screwed hole of air vent 2 periphery, it is achieved thereby that secondary oil divides the peace of filter screen 6 by end
Dress is fixing.It is further preferable that one can be formed with described on the staving around air vent 2
The depressed part 13 that flange 10 coordinates, so, after mounting, secondary oil divides the flange of filter screen 6
10 be placed at least partially in this depressed part 13, thus reduce volume of the present utility model.
It is highly preferred that also can make the degree of depth thickness more than described flange 10 of depressed part 13, so that method
Blue 10 scopes the most not protruding from (even including the end of the second screw) depressed part 13, from
And make volume the compactest.
This utility model additionally provides a kind of helical-lobe compressor, including above-mentioned oil content barrel.
This utility model additionally provides a kind of air-conditioning device, including above-mentioned helical-lobe compressor.
This utility model divides filter screen, to row by the secondary oil installed in the exhaust ports of oil content barrel
Go out the aerofluxus before compressor and carry out secondary filter, thus improve aerofluxus purity, increase separating of oil
Efficiency.
Certainly, it is above preferred implementation of the present utility model.It should be pointed out that, for this skill
For the those of ordinary skill in art field, on the premise of without departing from this utility model ultimate principle,
Can also make some improvements and modifications, these improvements and modifications are also considered as guarantor of the present utility model
Protect scope.
