Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of compressor accessories, in particular to a separator for reciprocating compressor. BACKGROUND

[0002] In the Chinese patent with application number 201920674466.8, a gas-liquid separator and a compressor are proposed, wherein the gas-liquid separator comprises: a shell provided with a gas-liquid separation cavity; an inlet provided at one end of the shell and communicated with the gas-liquid separation cavity; an outlet provided at the other end of the shell and communicated with the gas-liquid separation cavity; a flow guide pipe provided in the gas-liquid separation cavity, extending out from the outlet towards the inlet, and communicated with the outlet, and spaced apart from the inlet; at least one air passage structure is provided on the peripheral wall of the flow guide pipe or the end wall facing away from the inlet, and the air passage structure is communicated with the gas-liquid separation cavity and the inner cavity of the flow guide pipe; an impurity adsorption device comprising at least one first impurity adsorption structure is provided in the gas-liquid separation cavity. By providing the flow guide pipe, the liquid refrigerant and impurities are prevented from being directly discharged to the outlet, improving the gas-liquid separation effect. At the same time, by providing the impurity adsorption device, the impurities are hindered, preventing the impurities from entering the compressor, and the flow resistance of the refrigerant is not increased due to the setting of the filter screen, improving the performance of the compressor.

[0003] In the above technical solution, an indirect isolation method is used to avoid the direct linear transportation of impurities in the flowing gas, and a blocking method is used for transportation. However, after long-term use and accumulation, the internal condensed liquid will accumulate, causing the impurities and condensed liquid to be transported to the pipeline again, which will not achieve the effect of removing impurities and liquid. SUMMARY

[0004] The present application aims to solve the problems in the background art and provides a separator for reciprocating compressor which can automatically discharge accumulated liquid.

[0005] The technical scheme of the present application is: a separator for a reciprocating compressor, comprising a main sealing pipe and a pair of fixed rings fixed inside the main sealing pipe, an insulation pipe fixedly connected between the two fixed rings, a cooling liquid inlet pipe and a cooling liquid outlet pipe connected to the outside of the insulation pipe and communicated with the outside of the main sealing pipe, a rectangular plate fixed to the inside of each fixed ring, a reciprocating screw rod rotatably connected between the two rectangular plates, a reciprocating nut movably sleeved on the reciprocating screw rod, a scraping ring fixedly connected to the inner wall of the insulation pipe through the establishing plate, the left end of the reciprocating screw rod penetrating through the left rectangular plate and the inner left wall of the main sealing pipe and extending to the outside of the main sealing pipe, a motor fixed to the left side of the main sealing pipe, the output shaft of the motor fixedly connected with the left end of the reciprocating screw rod, a flow guide pipe communicated with the lower side of the insulation pipe and penetrating through the inner wall of the main sealing pipe, a buffer tank fixedly connected with the main sealing pipe and arranged on the lower side of the insulation pipe, a discharge pipe communicated with the lower end of the buffer tank, and a constant discharge mechanism arranged in the buffer tank.

[0006] Preferably, the left end of the main sealing pipe is connected with an inlet joint, and the outer circumferential surface of the main sealing pipe is connected with an outlet joint located on the left side of the insulation pipe.

[0007] Preferably, a pair of heat insulation rings for reducing heat conduction are fixedly sleeved on the insulation pipe and connected with the inner wall of the main sealing pipe.

[0008] Preferably, a guide rod is fixed between the two rectangular plates, the establishing plate is movably sleeved on the guide rod, and the guide rod and the reciprocating screw rod are jointly fixedly sleeved with a flow guide member located at the right end of the guide rod for flow guiding.

[0009] Preferably, the constant discharge mechanism comprises a fixed frame plate fixed in the buffer tank, a connecting fixed rod penetratingly arranged on the fixed frame plate, a sealing piston one fixed to the lower end of the connecting fixed rod and capable of sliding in the discharge pipe, a sealing piston two fixed to the upper end of the connecting fixed rod and capable of sliding in the flow guide pipe, and a transmission assembly arranged on the buffer tank and used for driving the connecting fixed rod to reciprocate up and down.

[0010] Preferably, the transmission assembly comprises a long connecting rod penetrating through the outside of the buffer tank, a biasing rod fixed to one end of the long connecting rod located on the inside of the buffer tank, a positioning shaft fixed to the right side of the biasing rod, a connecting main member movably sleeved on the positioning shaft and fixedly connected with the connecting fixed rod, and the left end of the long connecting rod is transmissionally connected with the reciprocating screw rod through a synchronous transmission assembly.

[0011] Preferably, a sliding groove for the positioning shaft to slide is formed in one side of the connecting main member, and the positioning shaft is located in the sliding groove.

[0012] Preferably, the buffer tank is connected to a level tube for displaying the liquid level inside the buffer tank.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] The coolant is transferred through the partition effect formed by the isolation tube and the fixed ring. In conjunction with the scraping action of the scraping ring connected to the plate on the reciprocating nut on the reciprocating screw, the condensate in the isolation tube is cleaned in time and can be easily guided to the bottom of the isolation tube and discharged into the buffer tank through the guide tube. In the fixed discharge assembly, the up and down movement of the connecting rod is realized through a multi-stage structural design, which enables intermittent timed discharge. At the same time, when discharging liquid from the buffer tank, the guide tube is sealed by the sealing piston, which reduces the direct discharge of gas from the main sealing tube and maintains the internal pressure stability.
