Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas-liquid separation equipment, in particular to a centrifugal air conditioner gas-liquid separator. BACKGROUND

[0002] Gas-liquid centrifugal separation mainly refers to gas-liquid cyclone separation. Because the centrifugal force can reach tens of times or even more than gravity, the liquid droplets in the gas flow are separated by using the centrifugal force. When the liquid and gas flow together, the centrifugal force field generated by the strong cyclone makes the phases with different densities move relatively. The liquid receives a centrifugal force greater than that of the gas, so as to collide with the wall surface of the cylinder and adhere to it. In addition, the gravity is used to achieve the separation purpose. It can separate smaller liquid droplets and has higher efficiency than gravity separation.

[0003] An important function of the gas-liquid separator is to prevent the compressor from being liquid struck. Liquid strike refers to the direct entry of liquid refrigerant into the cylinder of the compressor, which causes damage to the compressor. By filtering the gas, the liquid particles in the gas can be effectively separated to prevent the particles from entering the compressor, thereby protecting the equipment. In addition, the micro liquid droplets are separated by the wire mesh to further improve the efficiency of gas-liquid separation. However, the filter device in the equipment is not easy to clean in time. Long-term adsorption and separation use may cause excessive accumulation of dirt on the surface of the filter mechanism. The smooth passage of gas through the filter device will affect the service life of the filter device and reduce the efficiency of gas-liquid separation. In addition, if the filter device is replaced or cleaned frequently, the operation of the device needs to be stopped, which reduces the working efficiency of the device during use. Therefore, how to invent a centrifugal air conditioner gas-liquid separator to solve these problems has become a problem to be solved by the technical personnel in the field. SUMMARY

[0004] In order to make up for the above shortcomings, the present application provides a centrifugal air conditioner gas-liquid separator, which is designed to solve the problem of difficult timely cleaning of the filter device, reduce the efficiency of gas-liquid separation, and frequently replace or clean the filter device, which affects the working efficiency.

[0041] Further, the upper end of the cylinder cover 4 is fixedly connected with the exhaust pipe 5, and the lower end of the cylinder cover 4 is fixedly connected with a plurality of circumferentially arranged limiting insertion blocks 41; the lower end of the cylinder body 2 is fixedly connected with the drain pipe 1, the outer wall of the cylinder body 2 is provided with an air inlet 14, one end of the air inlet 14 is fixedly connected with the air inlet pipe 6, the outer wall of the cylinder body 2 is fixedly connected with the return pipe 3, and the upper end of the cylinder body 2 is provided with limiting insertion grooves 21 corresponding to the limiting insertion blocks 41.

[0042] Positioning of the cylinder body 2 and the cylinder cover 4: the limiting insertion grooves 21 arranged at the upper end of the cylinder body 2 can enable the cylinder cover 4 to be quickly inserted through the limiting insertion blocks 41, thereby limiting the position of the cylinder cover 4, so as to ensure the alignment of the bolt hole positions on the side walls of the cylinder body 2 and the cylinder cover 4, and to quickly fix the two through bolts, in addition, after the fixation of the cylinder cover 4, the limiting insertion blocks 41 can be extruded to limit the clamping blocks 711, so as to ensure the effective positioning of the upper filter plate 71 and to avoid the movement of the upper and lower filter plates 71 during the work process, thereby affecting the use effect.

[0043] Further, the inner wall of the cylinder body 2 is fixedly connected with the supporting ring 9 and the fixing ring 13, the supporting ring 9 is located below the fixing ring 13, the inner wall of the cylinder body 2 is fixedly connected with the flow guide plate 10, the flow guide plate 10 is arranged in a spiral shape, one end of the flow guide plate 10 away from the cylinder body 2 is fixedly connected with the wind shield 11, the upper end of the flow guide plate 10 is located on one side of the air inlet 14, and the upper end of the flow guide plate 10 is higher than the air inlet 14, the bottom end inner wall of the cylinder body 2 is fixedly connected with the side plate 15, the side plate 15 is arranged in an arc shape, and the side plate 15 is located on one side of the lower end of the flow guide plate 10.

[0044] Centrifugal separation of the cylinder body 2 to the gas: the flow guide plate 10 is arranged in a wave shape, after the gas is quickly pumped into the inside of the cylinder body 2 through the air inlet pipe 6, most of the gas spirally flows downward along the space formed by the flow guide plate 10 and the wind shield 11, so as to separate the gas and liquid through the action of centrifugal force, and the liquid generated during the separation process drips along the flow guide plate 10 to the inside of the cylinder body 2 for storage, and is discharged through the external on-off valve of the drain pipe 1, and in order to avoid the rapid dissipation of the separated gas, the side plate 15 is used to block the separated gas, so as to make the wind force gather and improve the subsequent utilization effect, in addition, the wave-shaped arrangement of the flow guide plate 10 can increase the contact area during the separation, thereby increasing the movement path of the gas-liquid mixture, so that more liquid is adsorbed on the flow guide plate 10, and the separation effect is enhanced.

[0045] Reference Figures 10-13, further; guide assembly 12 further comprises expansion cover 125 and fixed seat 1210, expansion cover 125 is fixedly connected with the lower end of outer tube 124, the inner wall of outer tube 124 is fixedly connected with support plate 128, outer tube 124 is located at the outer side of inner tube 127, the outer wall of inner tube 127 is fixedly connected with support plate 128, the lower end inner wall of inner tube 127 is fixedly connected with fixed seat 1210, the lower end of outer tube 124 is provided with drainage groove hole 1241, the upper end of inner tube 127 is fixedly connected with drainage cover 121, drainage cover 121 is funnel-shaped, drainage cover 121 is fixedly connected with support ring 9, the side wall of fixed seat 1210 is fixedly connected with shaft sleeve 1212, the side wall of fixed seat 1210 is provided with a plurality of circumferentially distributed air holes 1211; rotating rod 122 is rotatably connected with shaft sleeve 1212, the lower end of rotating rod 122 is fixedly connected with a plurality of circumferentially distributed wind baffles 126, the upper end of rotating rod 122 penetrates the side wall of fixed seat 1210, the outer wall of rotating rod 122 is fixedly connected with turbine vane 129, turbine vane 129 is located in the inner tube 127, the upper end of rotating rod 122 is fixedly connected with cross column 123 matched with cross groove 741.

[0046] The release of the gas after centrifugation by the guide assembly 12: when the gas passes through the side plate 15, it will blow towards the wind baffle 126, when the airflow passes through the separator, its speed and pressure will generate a force on the wind baffle 126, this force can push the wind baffle 126 to rotate, and the moment generated by the wind force is enough to overcome the inertia and friction of the wind baffle 126, so as to drive the rotating rod 122 to rotate, at the same time, the rotation of the wind baffle 126 also helps to guide the airflow more effectively, so that the gas-liquid is better separated, therefore, through the flow of wind force and the blocking of the wind baffle 126, the rotating rod 122 will rotate in the inner tube 127, and the stability of the rotating rod 122 during rotation is increased through the action of the shaft sleeve 1212, at the same time the rotating rod 122 rotates, the turbine vane 129 starts to work, at this time, part of the gas flows to the inside of the inner tube 127 through the air holes 1211 by itself, and the other part of the gas is absorbed by the wind generated by the rotation of the turbine vane 129, thereby increasing the flow rate of the gas, promoting the discharge of the gas to the upper end of the cylinder 2, and reducing the accumulation of gas at the bottom of the cylinder 2;

[0047] The guide of part of the gas by the outer tube 124: after the gas is rapidly pumped into the cylinder 2 by the inlet pipe 6, a small part of the gas may drift to the outside of the drainage plate 10 and the wind shield 11, at this time, due to the flow of the gas, it will enter the gap between the inner tube 127 and the outer tube 124, and the support plate 128 can be made of a condensation plate, therefore, after the gas enters the gap between the inner tube 127 and the outer tube 124, it is condensed into liquid by the condensation of the support plate 128, and flows to the side wall of the fixed seat 1210 and is discharged to the bottom of the cylinder 2 through the drainage groove hole 1241.

[0048] With reference to Figures 5-8 Further, the filtering assembly 7 further comprises an upper filtering plate 71 and a lower filtering plate 73, the outer wall of the upper filtering plate 71 is fixedly connected with a clamping block 711 matched with the limiting slot 21, the clamping block 711 is clamped with the limiting slot 21, the side wall of the upper filtering plate 71 is fixedly connected with a plurality of movable rods 712 arranged in a circumferential array, the movable rods 712 are arranged in a "T" shape, the side walls of the upper filtering plate 71 and the lower filtering plate 73 are fixedly connected with a plurality of annular strip plates 76 which are gradually expanded outward; the water absorbing part 72 is located between the upper filtering plate 71 and the lower filtering plate 73, the side wall of the lower filtering plate 73 is fixedly connected with a movable cylinder 731 corresponding to the movable rods 712, one end of the movable rods 712 is slidably connected with the inner wall of the movable cylinder 731, the outer wall of the movable cylinder 731 is provided with a telescopic spring 732, both ends of the telescopic spring 732 are fixedly connected with the side walls of the upper filtering plate 71 and the lower filtering plate 73 respectively.

[0049] The use of the filtering assembly 7: when the filtering assembly 7 is installed, one end of the lower filtering plate 73 is inserted into the inside of the cylinder body 2, and the clamping block 711 is inserted into the inside of the limiting slot 21, thereby completing the overall installation of the filtering assembly 7, and filtering the impurities and small particles in the gas through the upper filtering plate 71 and the lower filtering plate 73, preventing the accumulation of these impurities in the system, causing the blockage of the pipeline or equipment, the role of the movable rods 712, the movable cylinder 731 and the telescopic spring 732 is mainly to limit the position between the upper filtering plate 71 and the lower filtering plate 73, thereby ensuring the fixation of the position of the water absorbing part 72, the water absorbing part 72 can be made of water-absorbing sponge, which can absorb water in the gas while ensuring the passage of the gas, thereby avoiding the discharge of a small amount of steam from the exhaust pipe 5, to ensure that the discharged gas is more pure, in addition, the support of the water absorbing part 72 by the plurality of annular strip plates 76 can avoid the plugging of the upper filtering plate 71 and the lower filtering plate 73 by the water absorbing part 72, to ensure the flowability of the gas, in addition, the flow speed of the gas is not enough to dry the water absorbed by the water absorbing part 72.

[0050] Further, the filtering assembly 7 further comprises a rotating column 75 arranged in a "T" shape, the rotating column 75 is rotatably connected with the upper filtering plate 71, the outer wall of the rotating column 75 is slidably connected with the lower filtering plate 73, one end of the rotating column 75 located below the lower filtering plate 73 is fixedly connected with a cleaning plate 74, the side wall of the cleaning plate 74 is provided with a cross slot 741.

[0051] The automatic cleaning of the lower filter plate 73 by the cleaning plate 74: the upper end of the rotating rod 122 is inserted into the limiting cross column 123 and the cross groove 741, so that the rotating rod 122 drives the rotating column 75 to rotate synchronously, and then drives the soft brush on the side wall of the cleaning plate 74 to clean the surface of the lower filter plate 73, so as to ensure the filtering effect of the side wall of the lower filter plate 73 and reduce the blocking condition.

[0052] Embodiment two, refer to Figure 9 Further, one end of the telescopic air bag 81 is fixedly connected with the fixed plate 82, the fixed plate 82 is fixedly connected with the fixed ring 13, the fixed plate 82 is annularly arranged, a cavity 821 is formed in the inside of the fixed plate 82, an air inlet groove 822 is formed in the inner ring wall of the fixed plate 82, a shunt block 83 is fixedly connected with the inner wall of the cavity 821, the shunt block 83 is located on one side of the air inlet groove 822, the shunt block 83 is triangularly arranged, an air outlet groove 823 is formed on the side of the cavity 821 away from the air inlet groove 822, the air outlet groove 823 is fixedly connected with one end of the reflux pipe 3, the telescopic air bag 81 is in communication with the cavity 821, and the upper end of the telescopic air bag 81 is in contact with the side wall of the lower filter plate 73.

[0053] The automatic water drainage of the water absorbing element 72 by the extrusion assembly 8: when the water absorbing element 72 absorbs a large amount of water, its air permeability decreases, at this time, the air inlet amount of the air inlet pipe 6 remains unchanged, and the air outlet amount of the air outlet pipe 5 decreases, so the gas in the inner barrel 2 increases, the air pressure increases, so part of the gas is discharged through the water absorbing element 72, and another part of the gas enters the inside of the fixed ring 13 through the air inlet groove hole 822, and is divided into two sides by the flow divider 83 to flow into the inside of the cavity 821. Under normal circumstances, since the water absorbing element 72 has good air permeability, therefore, the gas rarely enters the inside of the cavity 821, and the opening of the air inlet groove hole 822 is larger than the port size of the return pipe 3, so the air inlet amount of the air inlet groove hole 822 is greater than the air outlet amount of the return pipe 3, so after a large amount of air enters the cavity 821, the internal pressure of the cavity 821 also increases, thereby expanding the expansion air bag 81, and then lifting the lower filter plate 73, so that the lower filter plate 73 moves upwards and compresses the expansion spring 732. At the same time, the inner wall of the movable barrel 731 is slidingly connected with the movable rod 712, so as to ensure the stability of the lower filter plate 73 during the upward movement of the lower filter plate 73. In the process of moving the lower filter plate 73 upwards, the water absorbing element 72 is extruded, so that the water accumulated in the water absorbing element 72 is squeezed out and discharged through the filter holes on the lower filter plate 73. In the process of discharging water, the surface particles of the lower filter plate 73 can be removed to improve the subsequent adsorption and separation effect. In addition, in order to prevent water from flowing out of the upper filter plate 71 during extrusion, a waterproof and air-permeable film can be attached to the side wall of the upper filter plate 71, so as to prevent water from flowing out of the air outlet pipe 5 and affecting the normal operation of the subsequent compressor. When the discharged water drops into the drainage cover 121, the funnel-shaped structure can effectively increase the falling speed of the water droplets, so that the water droplets slide down the inner wall of the inner pipe 127 to the surface of the fixed seat 1210, and finally discharged to the bottom end of the inner barrel 2 through the air hole 1211. The upward blowing of the wind may carry back a small part of the water droplets, but it does not affect the overall effect. When a large amount of water is discharged, the air permeability of the water absorbing element 72 gradually recovers, so the air outlet speed of the air outlet pipe 5 returns to normal. At this time, a large amount of gas is discharged, and the pressure in the inner barrel 2 gradually recovers. At this moment, the expansion air bag 81 is gradually contracted, so that the lower filter plate 73 is returned to its original position, waiting for the next extrusion and water drainage, reducing the number of shutdown and replacement.

[0054] It should be noted that the specific model and specification of the electrical device need to be selected and determined according to the actual specification of the device. The specific selection and calculation method adopts the existing technology in the art, and therefore will not be described in detail.

[0055] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
