Description

Technical Field

[0001] The invention relates to the technical field of gas-liquid separators, and in particular to a centrifugal air-conditioning gas-liquid separator. Background Art

[0002] Gas-liquid centrifugal separation mainly refers to gas-liquid cyclone separation. Because the centrifugal force can reach dozens of times or even more than gravity, centrifugal force is used to separate droplets in the airflow. The density of gas and liquid is different. When liquid and gas rotate and flow together, the centrifugal field generated by the strong cyclone is used to make phases with different densities move relative to each other. The liquid is subjected to a greater centrifugal force than the gas, so it collides with the wall of the cylinder and adheres to it. In addition, the effect of gravity achieves the separation purpose. It can separate smaller droplets with higher efficiency than gravity separation.

[0003] An important function of the gas-liquid separator is to prevent liquid hammer in the compressor. Liquid hammer refers to the liquid refrigerant directly entering the cylinder of the compressor, causing damage to the compressor. By filtering the gas, the liquid particles in it can be effectively removed to prevent these particles from entering the compressor, thereby protecting the equipment, and filtering tiny droplets through 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, and long-term use leads to excessive accumulation of dirt. The difficulty of gas passing through the filter device smoothly will also affect the service life of the filter device, reducing the efficiency of gas-liquid separation, and if the filter device is frequently replaced or cleaned, it is necessary to stop the operation of the device first, which reduces the working efficiency of the device when it is used.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1, refer to Figure 1-Figure 13 A centrifugal air-conditioning gas-liquid separator comprises a cylinder 2 and a cylinder cover 4, the cylinder 2 is connected to a drain pipe 1 and an air inlet pipe 6, the cylinder cover 4 is connected to an exhaust pipe 5, a support ring 9 and a fixing ring 13 are arranged inside the cylinder 2, a guide plate 10, a wind shield 11 and a side plate 15 are arranged inside the cylinder 2, a return pipe 3 is arranged on the outer wall of the cylinder 2, and further comprises: The filter assembly 7 is located inside the cylinder 2 and includes a water absorbing member 72; An extrusion assembly 8, which is located below the filter assembly 7, and includes a telescopic airbag 81 and a fixing plate 82; The guide assembly 12 is located inside the cylinder 2 . The guide assembly 12 includes a guide cover 121 , an outer tube 124 and an inner tube 127 . A rotating rod 122 is provided inside the inner tube 127 .

[0021] Furthermore; the upper end of the cylinder cover 4 is fixedly connected to the exhaust pipe 5, and the lower end of the cylinder cover 4 is fixedly connected to a plurality of limit plugs 41 distributed in a circular array; the lower end of the cylinder body 2 is fixedly connected to the drain pipe 1, and 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 to the air inlet pipe 6, the outer wall of the cylinder body 2 is fixedly connected to the return pipe 3, and the upper end of the cylinder body 2 is provided with a limit slot 21 corresponding to the limit plug 41.

[0022] Positioning of the cylinder body 2 and the cylinder cover 4: A limiting slot 21 is provided at the upper end of the cylinder body 2 so that the cylinder cover 4 can be quickly inserted through the limiting plug 41, thereby limiting the position of the cylinder cover 4, thereby ensuring the alignment of the bolt hole positions on the side walls of the cylinder body 2 and the cylinder cover 4, so that the two can be quickly fixed by bolts. In addition, after the cylinder cover 4 is fixed, the limiting plug 41 can be used to squeeze and limit the block 711 to ensure the effective positioning of the upper filter plate 71 to avoid up and down movement during operation and affecting the use effect.

[0023] Furthermore; the inner wall of the cylinder 2 is fixedly connected to the support ring 9 and the fixing ring 13 respectively, the support ring 9 is located below the fixing ring 13, the inner wall of the cylinder 2 is fixedly connected to the guide plate 10, the guide plate 10 is spirally arranged, the end of the guide plate 10 away from the cylinder 2 is fixedly connected to the wind shield 11, the upper end of the guide plate 10 is located on one side of the air inlet 14, the upper end of the guide plate 10 is higher than the air inlet 14, the inner wall of the bottom end of the cylinder 2 is fixedly connected to the side plate 15, the side plate 15 is arc-shaped, and the side plate 15 is located on one side of the lower end of the guide plate 10.

[0024] Centrifugal separation of gas by the cylinder 2: the guide plate 10 is set to a wave shape. After the gas is quickly pumped into the cylinder 2 through the air inlet pipe 6, most of the gas spirals downward along the space formed by the guide plate 10 and the wind shield 11, so as to separate the gas and liquid through the action of centrifugal force. The liquid generated in the separation process drips along the guide plate 10 to the inside of the cylinder 2 for storage, and is discharged through the external switch valve of the drain pipe 1. After the separated gas is discharged, it is blocked by the side plate 15 to avoid rapid dissipation, thereby concentrating the wind force and improving the subsequent utilization effect. In addition, the guide plate 10 can increase the contact area during separation through the wave-shaped setting, thereby increasing the movement path of the gas-liquid mixture, so that more liquid adheres to the guide plate 10, and the separation effect is enhanced.

[0025] Reference Figure 10-13, further; the guide assembly 12 also includes an expansion cover 125 and a fixed seat 1210, the expansion cover 125 is fixedly connected to the lower end of the outer tube 124, the inner wall of the outer tube 124 is fixedly connected to a support plate 128, the outer tube 124 is located on the outside of the inner tube 127, the outer wall of the inner tube 127 is fixedly connected to the support plate 128, the inner wall of the lower end of the inner tube 127 is fixedly connected to the fixed seat 1210, the lower end of the inner tube 127 is provided with a drainage slot 1241, the upper end of the inner tube 127 is fixedly connected to the drainage cover 121, the drainage cover 121 is funnel-shaped, and the drainage cover 121 is fixedly connected to the support ring 9 The side wall of the fixed seat 1210 is fixedly connected with a shaft sleeve 1212, and the side wall of the fixed seat 1210 is provided with a plurality of vent holes 1211 distributed in a circular array; the rotating rod 122 is rotatably connected to the shaft sleeve 1212, and the lower end of the rotating rod 122 is fixedly connected with a plurality of wind shield plates 126 distributed in a circular array, the upper end of the rotating rod 122 passes through the side wall of the fixed seat 1210, and the outer wall of the rotating rod 122 is fixedly connected with a turbine blade 129, and the turbine blade 129 is located inside the inner tube 127, and the upper end of the rotating rod 122 is fixedly connected with a cross column 123 that matches the cross slot 741.

[0026] The guide assembly 12 releases the gas after centrifugation: when the gas passes through the side plate 15, it will blow toward the wind shield 126. When the airflow passes through the separator, its speed and pressure will exert a force on the wind shield 126. This force can push the wind shield 126 to rotate, and the torque generated by the wind is sufficient to overcome the inertia and friction of the wind shield 126, so that it drives the rotating rod 122 to rotate. At the same time, the rotation of the wind shield 126 also helps to guide the airflow more effectively and separate the gas and liquid better. Therefore, the flow of wind and the blocking of the wind shield 126 will The rotating rod 122 is driven to rotate inside the inner tube 127, and the stability of the rotating rod 122 during the rotation process is increased through the action of the shaft sleeve 1212. When the rotating rod 122 rotates, the turbine blades 129 are driven to start working. At this time, the gas flows to the inside of the inner tube 127 through the vent holes 1211 by its own drifting, and the other part of the gas is absorbed by the wind force generated by the rotation of the turbine blades 129, thereby accelerating the flow rate of the gas, promoting the gas to be discharged to the upper end of the cylinder 2, and reducing the accumulation of gas at the bottom of the cylinder 2; The outer tube 124 guides part of the gas: after the air inlet pipe 6 quickly pumps gas into the interior of the cylinder 2, a small amount of gas may drift to the outside of the guide plate 10 and the wind shield 11. At this time, due to the flow of gas, the gas will enter the middle of 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 middle gap between the inner tube 127 and the outer tube 124, the condensation effect of the support plate 128 promotes the steam in the gas to condense into liquid faster, 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 1241.

[0027] Reference Figure 5-Figure 8 , further; the filter assembly 7 also includes an upper filter plate 71 and a lower filter plate 73, the outer wall of the upper filter plate 71 is fixedly connected with a block 711 that matches the limit slot 21, the block 711 is snapped with the limit slot 21, the side wall of the upper filter plate 71 is fixedly connected with a plurality of movable rods 712 distributed in a circumferential array, the movable rods 712 are arranged in a "T" shape, and the side walls of the upper filter plate 71 and the lower filter plate 73 are fixedly connected with a plurality of annular strips 76 that expand outward in sequence; the water absorbing member 72 is located between the upper filter plate 71 and the lower filter plate 73, and the side wall of the lower filter plate 73 is fixedly connected with a movable cylinder 731 corresponding to the movable rod 712, one end of the movable rod 712 is slidably connected to the inner wall of the movable cylinder 731, and the outer wall of the movable cylinder 731 is provided with a telescopic spring 732, and the two ends of the telescopic spring 732 are respectively fixedly connected to the side walls of the upper filter plate 71 and the lower filter plate 73.

[0028] Use of filter assembly 7: When installing filter assembly 7, one end of lower filter plate 73 can be inserted into the interior of cylinder body 2, and block 711 can be inserted into the interior of limit slot 21, so as to complete the overall installation of filter assembly 7, and filter impurities and fine particles in gas through upper filter plate 71 and lower filter plate 73 to prevent these impurities from accumulating in the system and causing blockage of pipelines or equipment, and the movable rod 712, movable cylinder 731 and telescopic spring 732 are mainly used to adjust the upper filter plate 71 and lower filter plate 73. The position between the filter plates 73 is limited to ensure the fixation of the position of the water absorbent member 72, and the water absorbent member 72 can be made of a water-absorbing sponge, which can absorb moisture in the gas while ensuring the passage of gas, thereby preventing a small amount of steam from being discharged from the exhaust pipe 5, so as to ensure that the discharged gas is purer. In addition, the support of the water absorbent member 72 by multiple annular strips 76 can prevent the water absorbent member 72 from blocking the upper filter plate 71 and the lower filter plate 73, thereby ensuring the fluidity of the gas. In addition, the gas circulation speed is not sufficient to dry the moisture absorbed by the water absorbent member 72.

[0029] Furthermore, the filter assembly 7 also includes a rotating column 75, which is arranged in a "T" shape. The rotating column 75 is rotatably connected to the upper filter plate 71, and the outer wall of the rotating column 75 is slidably connected to the lower filter plate 73. One end of the rotating column 75 located below the lower filter plate 73 is fixedly connected to a cleaning plate 74, and a cross groove 741 is opened on the side wall of the cleaning plate 74.

[0030] Automatic cleaning of the lower filter plate 73 by the cleaning plate 74: the upper end of the rotating rod 122 is limitedly plugged in through the cross column 123 and the cross groove 741, so that the rotating rod 122 drives the rotating column 75 to rotate synchronously while rotating, 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, thereby ensuring the filtering effect of the side wall of the lower filter plate 73 and reducing blockage.

[0031] Example 2, refer to Fig. 9 , further; one end of the telescopic airbag 81 is fixedly connected to the fixed plate 82, the fixed plate 82 is fixedly connected to the fixed ring 13, the fixed plate 82 is arranged in an annular shape, a cavity 821 is opened inside the fixed plate 82, an air inlet slot 822 is opened on the inner wall of the fixed plate 82, a diverter block 83 is fixedly connected to the inner wall of the cavity 821, the diverter block 83 is located on one side of the air inlet slot 822, the diverter block 83 is arranged in a triangular shape, an exhaust slot 823 is opened on the side of the cavity 821 away from the air inlet slot 822, the exhaust slot 823 is fixedly connected to one end of the reflux pipe 3, the telescopic airbag 81 is connected to the cavity 821, and the upper end of the telescopic airbag 81 contacts the side wall of the lower filter plate 73.

[0032] Automatic drainage of the water-absorbing member 72 by the extrusion assembly 8: When the water-absorbing member 72 absorbs more water, its air permeability decreases. At this time, the air intake of the air inlet pipe 6 remains unchanged, while the air exhaust of the exhaust pipe 5 decreases. Therefore, the gas inside the cylinder 2 increases and the air pressure increases. Therefore, part of the gas is discharged through the water-absorbing member 72, while the other part of the gas enters the interior of the fixing ring 13 through the air inlet slot 822, and the gas is divided into two sides by the diverter block 83 to evenly flow to the interior of the cavity 821. Under normal circumstances, due to the good air permeability of the water-absorbing member 72, very little gas enters. The air inlet slot 822 is larger than the port size of the return pipe 3, so the air intake of the air inlet slot 822 is larger than the exhaust of the return pipe 3. Therefore, after a large amount of air is taken into the cavity 821, its internal pressure will also increase, thereby causing the telescopic airbag 81 to expand and expand, thereby lifting the lower filter plate 73, causing the lower filter plate 73 to move upward and compress the telescopic spring 732. At the same time, the inner wall of the movable cylinder 731 is slidably connected with the movable rod 712, so as to ensure the stability of the lower filter plate 73 during the upward movement. The water absorbing member 72 is squeezed to squeeze out the water accumulated inside it and discharge it through the filter holes on the lower filter plate 73. In the process of water discharge, some particles on the surface of the lower filter plate 73 can be removed to improve the subsequent filtering effect. In addition, in order to prevent water from flowing out of the upper filter plate 71 during squeezing, a waterproof and breathable membrane can be attached to the side wall of the upper filter plate 71 to prevent water from being discharged from the exhaust pipe 5 and affecting the normal operation of the subsequent compressor. When the discharged water drips onto the drainage cover 121, the funnel-shaped setting can effectively increase the falling speed of the water droplets. The water droplets slide along the inner wall of the inner tube 127 to the surface of the fixed seat 1210, and are finally discharged from the vent hole 1211 to the bottom end of the cylinder 2. The upward blowing of the wind may cause a small part of the water droplets to flow back, but it does not affect the overall effect. After a large amount of water is discharged, the air permeability of the water absorbent 72 is gradually restored, so the exhaust speed of the exhaust pipe 5 returns to normal. At this time, a large amount of gas is discharged and the internal pressure of the cylinder 2 is gradually restored. At this moment, the telescopic airbag 81 is also gradually shrinking, so that the lower filter plate 73 returns to its position, waiting for the next squeezing and drainage, reducing the number of shutdowns and replacements.

[0033] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
