Preferably, baffle groups and gas-liquid filter net are arranged in the same cylindrical shell of compressor oil box top, the end opening setting that cylindrical shell is nearer apart from tank lubrication oil, gas-liquid filter net is arranged at the baffle groups top one time, secondary baffling assembly is arranged at the inside top of compressor housing, and cylindrical shell is communicated with by balance tube with compressor housing, and balance tube has a suction port that is connected with cylindrical shell, an air outlet that is connected with compressor housing, flow-stopping plate place the below, air outlet.
Preferably, baffle groups comprises a deflection plate more than at least, and one time the deflection plate interval arranges, and is fixed in the cylindrical shell so that downward-sloping mode is staggered, and deflection plate and between the fixing end of cylindrical shell and the cylindrical shell does not leave air gap.
Preferably, the diameter of cylindrical shell is D, is spaced apart 0.15D-0.35D between deflection plate.
Preferably, downtilt angles is less than or equal to 10 degree.
Preferably, flow-stopping plate surrounds secondary baffling square cavity with compressor housing above the compressor air suction mouth.
Preferably, secondary baffling square cavity flows out the end opening setting at air-flow.
Preferably, the secondary baffle groups comprises at least one secondary deflection plate, one side fixing of secondary deflection plate one end and flow-stopping plate leaves air gap between the other end and the secondary baffling square cavity.

As can be seen from the above technical solutions, the embodiment of the invention has the following advantages:
(1) utilizes gas-liquid mixture air-flow velocity and the flow direction to change and realize gas-liquid separation, do not need gas-liquid filter net is made particular design;
(2) by being set repeatedly, baffling can improve the gas-liquid separation precision;
(3) can in time adjust deflection plate number and baffling number of times according to the separation accuracy needs, applicability is strong.
Description of drawings
Figure 1 shows that embodiment of the invention structural representation;
Figure 2 shows that the plan structure schematic representation of secondary baffling square cavity in the embodiment of the invention.
Embodiment
The embodiment of the invention provides a kind of gas-liquid separation structure of compressor, be used for utilizing gas-liquid mixture when flow velocity reduction and flow direction change, because the existence of viscosity, the characteristic that drop invests obstacle easily reaches the purpose of gas-liquid separation, can obtain higher separation accuracy by baffling repeatedly, improve the separating effect of the gas-liquid mixture that refrigerant and lubricant oil form in the compressor assembly.
With reference to figure 1, be depicted as a kind of gas-liquid separation structure of compressor of the embodiment of the invention, it comprises baffle groups 3 one time, gas-liquid filter net 4, and further be provided with flow-stopping plate 6 and secondary baffle groups 7, wherein, baffle groups 3 and gas-liquid filter net 4 are arranged in the same cylindrical shell 2 at compressor sump 1 top, the end opening setting that cylindrical shell 2 lubricant oil in fuel tank 1 is nearer, gas-liquid filter net 4 is arranged at baffle groups 3 tops one time, flow-stopping plate 6 and secondary baffle groups 7 are arranged at the inside top of compressor housing 5, cylindrical shell 2 is communicated with by balance tube 8 with compressor housing 5, balance tube has a suction port that is connected with cylindrical shell 2, an air outlet that is connected with compressor housing 5, flow-stopping plate 6 place below, balance tube air outlet.
In order to obtain better first gas-liquid separation effect, baffle groups 3 comprises a deflection plate more than at least, one time the deflection plate interval arranges, and be fixed in the cylindrical shell 2 with downward-sloping mode interleaved, and deflection plate and between the fixing end of cylindrical shell 2 and the cylindrical shell 2 does not leave certain air gap, the diameter of supposing cylindrical shell 2 is D, and then the interval between deflection plate is set as 0.15D-0.35D, and downtilt angles is less than or equal to 10 degree.
Secondary deflection plate assembly comprises flow-stopping plate 6 and at least one secondary deflection plate of being located at compressor air suction mouth place, one side fixing of secondary deflection plate one end and described flow-stopping plate 6 leaves air gap between the other end and the secondary baffling square cavity.The cavity that the compressor inlet top is surrounded by flow-stopping plate is square, form secondary baffling square cavity, and flow out the end opening setting at air-flow, referring to Fig. 2, be depicted as the plan structure schematic representation of secondary baffling square cavity, if its minor face is L, in order to reach better secondary baffling effect, the length of secondary flow-stopping plate is made as 0.1L-0.4L.
