Can find out that from above technical scheme the utility model embodiment has the following advantages:
(1) utilizes the gas-liquid mixture air-flow velocity to realize gas-liquid separation, do not need gas-liquid filter net is made particular design with flowing to change;
(2) through 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
Shown in Figure 1 is the utility model example structure sketch map;
Shown in Figure 2 is the plan structure sketch map of secondary baffling square cavity among the utility model embodiment.
The specific embodiment
The utility model embodiment provides a kind of compressor vapor-liquid separating structure; Be used to utilize 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 through baffling repeatedly, improves the separating effect of the gas-liquid mixture that refrigerant and lubricating oil form in the compressor assembly.
With reference to figure 1, be depicted as a kind of compressor vapor-liquid separating structure of the utility model embodiment, it comprises baffle groups 3, gas-liquid filter net 4; And further be provided with flow-stopping plate 6 and secondary baffle groups 7; Wherein, a baffle groups 3 is arranged in the same cylindrical shell 2 at compressor sump 1 top the end opening setting that cylindrical shell 2 lubricating oil in fuel tank 1 is nearer with gas-liquid filter net 4; 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, and cylindrical shell 2 is communicated with through balance pipe 8 with compressor housing 5, and balance pipe has an air inlet that is connected with cylindrical shell 2; A gas outlet that is connected with compressor housing 5, flow-stopping plate 6 place below, balance pipe gas outlet.
In order to obtain better first gas-liquid separation effect; One time baffle groups 3 comprises a deflection plate more than at least, and one time deflection plate is provided with at interval, and is fixed in the cylindrical shell 2 with downward-sloping mode interleaved; And deflection plate and between 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 at 0.15D-0.35D, and downtilt angles is smaller or equal to 10 degree.
Secondary deflection plate assembly comprises the 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 said 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, referring to Fig. 2 at air-flow; Be depicted as the plan structure sketch map 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.
Technical scheme through present embodiment; Machine is from the refrigerant of fuel tank and the gas-liquid mixture of the lubricating oil formation baffle groups of flowing through earlier successively a time in air conditioner compressed; Because the reduction of air velocity and the change of direction, lubricating oil can invest on deflection plate, and gas gets into next piece deflection plate again after the direction change; Through baffling repeatedly, most lubricating oil is separated and under the effect of gravity, flows back into fuel tank along a deflection plate; Getting into the gas-liquid filter net with certain order number through the gas-liquid mixture after the baffle groups separation separates; Gas after initial gross separation and part residual liquid enter to the compressor housing place along balance pipe; Owing to communicate with compressor inlet here, this part gas-liquid mixture is easy to be inhaled into the compressor inlet place, and the utility model embodiment avoids remaining lubricating oil gas to get into compressor assembly through flow-stopping plate and secondary baffle groups are set at the compressor housing place again; Flow-stopping plate and secondary baffle groups make the flow velocity of gas change with flowing to once more; Improve separating effect, the lubricating oil that here filters can draw and is back to fuel tank through pipeline is set, at last; Purer cold media gas is inhaled into compressor inlet, has improved systematic function.
