Description

Technical Field

[0002] The function of the oil separator is to separate the lubricating oil from the high-pressure steam discharged from the refrigeration compressor to ensure the safe and efficient operation of the device. The efficiency of the oil separator has always been a key factor affecting the overall performance of many equipment. If the oil separator is inefficient, it will cause too much oil to enter the heat exchanger, forming an oil film inside the heat exchanger, increasing the thermal resistance and affecting the heat exchange effect; it will also cause too little oil to return to the compressor, increasing internal wear of the compressor and affecting the life and reliability of the compressor. Therefore, there is an urgent need to improve the efficiency of the oil separator.

[0003] The Chinese patent with authorization announcement number CN102914105B discloses an oil separator, which removes components such as filter screen partitions, reduces inlet and outlet pressure losses, and reduces the volume of the oil-gas separator, which is conducive to the miniaturization design of the air-conditioning system; the oil separator is reduced in size and can be directly connected in series to the compressor exhaust pipeline through the inlet and exhaust ports, which can play a role in noise reduction; oil droplets are collected by the liquid collecting net, which improves the efficiency of oil separation, reduces the amount of oil entering the heat exchanger, and improves the heat exchange effect; the compressor's oil return is timely and sufficient to ensure the reliable and stable operation of the compressor.

A transmission mechanism is provided at the bottom of the rotating column 302. The transmission unit converts the directional rotation of the rotating unit into the lifting motion of the lifting mechanism through the steering adjustment mechanism and the transmission mechanism.

[0022] like Figures 1 to 4 As shown, in a specific embodiment, the rotating unit further includes a sealing ring 100, a cover plate 107 is fixedly connected to both ends of the sealing ring 100, an inner core 102 is movably connected in the sealing ring 100, and the edge of the inner core 102 is sealed and connected to the inner wall of the sealing ring 100, and the rotating unit further includes a limiting mechanism, which includes a pad 101, which is fixedly connected to the upper and lower ends of the inner core 102, a first slide groove 106 is provided on the pad 101, and the boss 105 is slidably installed in the first slide groove 106. In this setting, when the sealing plate 104 slides in the air groove 103, the boss 105 slides in the first slide groove 106 to limit the sealing plate 104.

In this configuration, the direction of the screw rod 215 in each cleaning unit is set so that the pressure rollers 207 in the cleaning units corresponding to the two filter bags 113 on the same side keep moving in the same direction, and move in the opposite direction to the pressure rollers 207 in the cleaning units corresponding to the two filter bags 113 on the other side, thereby realizing the alternating movement of the pressure rollers 207 on both sides.

[0024] like Figures 8 to 9 As shown, further, the cleaning unit also includes a dislocation moving mechanism, which includes a mounting shaft 208, which is fixedly mounted on the support frame 205, and a rotating plate 210 is rotatably mounted on one end of the mounting shaft 208, and a torsion spring 209 is installed between the rotating plate 210 and the mounting shaft 208. A limit block 211 is fixedly mounted on one side of the support frame 205, and the limit block 211 is adapted to the rotating plate 210. The dislocation moving mechanism also includes a fixed plate 212, and a guide plate 213 is fixedly mounted on one side of the fixed plate 212, and the guide plate 213 is adapted to the rotating plate 210. In this configuration, the torsion force of the torsion spring 209 acts on the rotating plate 210 so that the rotating plate 210 is continuously subjected to torsion. When the rotating plate 210 is on the side of the guide plate 213 close to the filter bag 113, one side of the guide plate 213 presses against the rotating plate 210. When the rotating plate 210 is on the other side of the guide plate 213, the rotating plate 210 loses the obstruction of the guide plate 213 and rotates to a position in contact with the limit block 211.

[0025] Example 3 like Fig.14 As shown, in a specific embodiment, a first connecting plate 303 is rotatably mounted on the side of the rotating column 302, a counterweight 304 is fixedly mounted on one end of the first connecting plate 303, a second connecting plate 305 is rotatably mounted on one side of the first connecting plate 303, a pressing block 306 is rotatably mounted on one end of the second connecting plate 305, a push rod 307 is rotatably mounted on the bottom of the pressing block 306, and a clamping block 308 is rotatably connected to the push rod 307. In this configuration, the rotating column 302 drives the counterweight 304 to rotate, and the counterweight 304 swings outward under the action of centrifugal force, and drives the pressing block 306 to move downward through the first connecting plate 303 and the second connecting plate 305, and at this time, the pressing block 306 drives the clamping block 308 to extend through the push rod 307.

[0026] like Figures 10 to 14 As shown, further, the first gear ring 309 and the second gear ring 310 are connected by a bearing, and the first gear ring 309 and the second gear ring 310 are both movably sleeved on the outer bottom of the rotating column 302, and the first gear ring 309 and the second gear ring 310 are respectively meshed and connected with the first gear 312 and the second gear 313 on one side, and the first gear 312 and the second gear 313 are meshed with each other, and the bottom of the second gear ring 310 is fixedly installed with a connecting sleeve 314, and the bottom of the connecting sleeve 314 is installed with a third gear 315, and the third gear 315 is rotatably installed on the top of the distribution chamber 112. In this setting, the first gear ring 309 and the second gear ring 310 are meshed through the first gear 312 and the second gear 313, so that the first gear ring 309 and the second gear ring 310 rotate in opposite directions, so that when the block 308 is aligned with the first gear ring 309 or the second gear ring 310, the second gear ring 310 rotates in the opposite direction.

[0027] like Figure 6 , Figure 11 to Figure 12 As shown, further, the transmission mechanism includes a fixed frame 316, the fixed frame 316 is fixedly mounted on the top of the distribution chamber 112, a fourth gear 317 is rotatably mounted on the fixed frame 316, a rotating shaft is mounted at the bottom of the fourth gear 317, a first bevel gear 318 is mounted at the bottom of the rotating shaft, a second bevel gear 319 is meshedly connected to the side of the first bevel gear 318, a transmission shaft 321 is fixedly mounted at one end of the second bevel gear 319, a connecting frame 320 is movably sleeved between the transmission shaft 321 and the rotating shaft, and the transmission mechanism also includes a third bevel gear 323 and a fourth bevel gear 330. 24. The third bevel gear 323 and the fourth bevel gear 324 mesh with each other. The third bevel gear 323 is movably inserted on the transmission shaft 321. A mounting tube 322 is rotatably installed at one end of the third bevel gear 323. The mounting tube 322 is movably sleeved on the transmission shaft 321, and the mounting tube 322 is rotatably connected to the fourth bevel gear 324. A synchronous wheel 325 is installed at the end of the screw rod 215, and a synchronous belt 326 is installed between two adjacent synchronous wheels 325. The synchronous wheel 325 close to the fourth bevel gear 324 is fixedly installed at the bottom of the fourth bevel gear 324. In this configuration, the cross-section of the transmission shaft 321 is of a special shape to keep the second bevel gear 319 and the third bevel gear 323 rotating synchronously while meeting the sliding requirements of the third bevel gear 323. When the pressure roller 207 is on different sides of the guide plate 213, the position of the lead screw 215 is driven to change. At this time, the fourth bevel gear 324 and the third bevel gear 323 follow the position change. The active connection between the transmission shaft 321 and the third bevel gear 323 provides the position change condition for the third bevel gear 323 and the fourth bevel gear 324.

[0028] like Figure 5 , Figure 6 , Fig.11 , Fig.15As shown, further, the transmission unit also includes a trigger mechanism, which includes a sleeve 300, a plug-in shaft 301 is movably inserted at the bottom of the sleeve 300, the plug-in shaft 301 is fixedly connected to the rotating column 302, a mounting ring 330 is fixedly installed on the sleeve 300, a fixing ring 328 is fixedly installed on the plug-in shaft 301, a second spring 329 is movably sleeved between the plug-in shaft 301 and the outer side of the sleeve 300, the second spring 329 is fixedly connected to the fixing ring 328 and the mounting ring 330, an electromagnet 327 is fixedly installed at the bottom of the cover plate 107 located below, the electromagnet 327 is aligned with the fixing ring 328, and sensors 216 are installed at both ends of one of the mounting plates 200, and the sensor 216 is electrically connected to the electromagnet 327. In this setting, when the sensor 216 detects the support frame 205, it sends out an electrical signal to switch the electromagnet 327 between the standby state and the working state. When the electromagnet 327 is in the working state, the electromagnet 327 adsorbs the fixed ring 328 to drive the rotating column 302 to move. At this time, the block 308 is aligned with the first gear ring 309. When the electromagnet 327 is in the standby state, the elastic force of the second spring 329 acts on the fixed ring 328 to make the rotating column 302 move in the opposite direction. At this time, the block 308 is aligned with the second gear ring 310.

[0029] like Figure 1 to Figure 2 As shown, further, an air inlet 109 is installed on one side of the sealing ring 100, and a transfer chamber 110 is installed on the other side, a conduit 111 is installed at one end of the transfer chamber 110, the conduit 111 is connected to the distribution chamber 112, and a protective shell 331 is installed between the shell 114 and the cover plate 107. In this configuration, the gas introduced from the air inlet 109 enters the transfer chamber 110 and then enters the distribution chamber 112, and then enters each filter bag 113 after passing through the distribution chamber 112.

[0030] The implementation principle of the oil separator for automobile air conditioner of the present embodiment is as follows: when in use, align the air inlet 109 with the air outlet of the compressor. When the compressor is working, the high-pressure gas enters the inner core 102 through the air inlet 109 and fills into the air groove 103. The side wall of the air groove 103 is acted upon by the air pressure to make the inner core 102 rotate as a whole. At the same time, the air pressure drives the sealing plate 104 to move. During the movement of the sealing plate 104, the boss 105 is driven to move. The boss 105 slides along the second slide groove 108 to drive the inner core 102 to rotate further. When the inner core 102 drives the gas to rotate to the transfer chamber 110, the boss 105 is reset under the action of the second slide groove 108 to discharge the gas into the transfer chamber 110. The gas enters the distribution chamber 112 through the transfer chamber 110 and the conduit 111, and then enters the filter bag 113 for oil and gas separation. When the inner core 102 rotates, the sleeve 300 is driven to rotate, the sleeve 300 drives the insertion shaft 301 to rotate, the insertion shaft 301 drives the rotating column 302 to rotate, the rotating column 302 drives the counterweight block 304 to rotate, the counterweight block 304 swings outward under the action of centrifugal force, and drives the pressure block 306 to move downward through the first connecting plate 303 and the second connecting plate 305, at this time, the pressure block 306 drives the block 308 to extend through the push rod 307, and the block 308 abuts against the tooth groove 311 to drive the first gear ring 309 to move, and the first gear ring 309 drives the second gear ring 310 to rotate through the first gear 312 and the second gear 313, so that the second gear ring 310 and the rotating column 302 are rotated. The driving direction is opposite, the second gear ring 310 drives the connecting sleeve 314 to rotate, the connecting sleeve 314 drives the third gear 315 to rotate, the third gear 315 drives the fourth gear 317 to rotate by meshing, the fourth gear 317 drives the first bevel gear 318 to rotate, the first bevel gear 318 drives the second bevel gear 319 to rotate by meshing, the second bevel gear 319 drives the third bevel gear 323 to rotate through the transmission shaft 321, the third bevel gear 323 drives the fourth bevel gear 324 to rotate, and the fourth bevel gear 324 drives the synchronous wheel 325 to rotate, so that the screw rod 215 rotates, and the screw rod 215 drives the adapting set 214 to move, so that the support frame 205 and the pressure roller 207 move; When the support frame 205 moves to the sensor 216, the support frame 205 is at one end of the screw rod 215. At this time, the screw rod 215 cannot continue to rotate, so that the rotating column 302 cannot rotate, so that the counterweight block 304 drops, and the clamping block 308 is retracted and disengaged from the tooth groove 311. At this time, the sensor 216 controls the electromagnet 327 to switch to the standby state, and the rotating column 302 is displaced under the coordinated action of the second spring 329. At this time, the clamping block 308 follows the movement and aligns with the tooth groove 311 corresponding to the second gear ring 310. At the same time, the rotating column 302 rotates again under the action of the inner core 102, so that the clamping block 308 drives the second gear ring 310 to rotate. At this time, the rotating column 302 has the same rotation direction as the second gear ring 310. The second gear ring 310 drives the screw rod 215 to rotate through the transmission unit, and the screw rod 215 drives the support frame 205 and the pressure roller 207 to move in the opposite direction through the adapter sleeve 214; When the support frame 205 moves downward, the elastic force of the first spring 202 makes the positioning rod 204 approach the filter bag 113, and then the pressure roller 207 is squeezed toward the filter bag 113 through the support frame 205. The filter bag 113 is squeezed by the pressure rollers 207 on both sides so that the adhered lubricating oil is squeezed out. When the support frame 205 moves to the bottom, the rotating plate 210 rotates under the action of the torsion spring 209 and fits with the limit block 211. When the support frame 205 moves upward, the rotating plate 210 interacts with the guide plate 213 to move the support frame 205, thereby separating the pressure roller 207 from the filter bag 113, so that the pressure roller 207 will not drive the filter bag 113 when it rises.
