Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separation technology, and in particular to a gas-liquid separation device. Background Technology

[0002] Gas-liquid separation is a crucial operational step in numerous industrial production processes, widely applied in petrochemicals, food and beverage, and environmental protection. For example, in petroleum refining, crude oil undergoes distillation and other processes to produce a large amount of liquid products mixed with gas. Efficient separation of the gas and liquid is essential to ensure the smooth operation of subsequent processing and the stability of product quality. In chemical synthesis reactions, the reaction products are often also in a gas-liquid mixture; the effectiveness of gas-liquid separation directly affects the reaction conversion rate and product purity. Therefore, developing high-performance gas-liquid separation devices is of paramount importance for improving industrial production efficiency, reducing costs, and ensuring product quality.

[0003] Existing gas-liquid separation devices typically employ the principle of gravity settling. Their mechanical structure mainly consists of a large separation container. The mixed gas and liquid fluids enter from one end of the container, and utilizing the density difference between the gas and liquid, the liquid gradually settles to the bottom of the container under the influence of gravity, while the gas rises to the top, thus achieving separation.

[0004] In existing gas-liquid separation devices, the gas is often dispersed in the liquid in the form of tiny bubbles, which makes it difficult to escape from the liquid quickly. This results in low gas-liquid separation efficiency, and a large amount of incompletely separated gas-liquid mixture flows into subsequent reaction equipment, thereby reducing reaction efficiency. Therefore, a gas-liquid separation device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a gas-liquid separation device, which aims to improve the problem of low gas-liquid separation efficiency caused by the difficulty of gas escaping from liquid quickly in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gas-liquid separation device includes a separation tank, a support fixedly connected to the side wall of the separation tank, a top plate provided on the upper surface of the separation tank, a liquid inlet pipe fixedly connected inside the top plate, an air outlet pipe fixedly connected to the side wall of the separation tank, a filter screen provided on the side wall of the air outlet pipe, a liquid outlet pipe fixedly connected to the bottom of the separation tank, a stirring assembly provided on the lower surface of the top plate, and a fixing assembly provided on the side wall of the air outlet pipe.

[0008] The stirring assembly includes a rotating rod and a stirring rod. A motor is fixedly connected to the upper surface of the top plate. A rotating block is fixedly connected to the output end of the motor. A fixed sleeve is fixedly connected inside the top plate. A gear one is fixedly connected to the side wall of the fixed sleeve. A connecting block is fixedly connected to the side wall of the rotating block. The side wall of the rotating rod is rotatably connected to the inside of the connecting block. A gear two is fixedly connected to the side wall of the rotating rod. The upper surface of the stirring rod is fixedly connected to the lower surface of the rotating rod.

[0009] As a further description of the above technical solution:

[0010] The fixing component includes a lower sleeve and an upper sleeve, wherein the lower sleeve and the upper sleeve are attached to the air outlet pipe and the side wall of the filter screen;

[0011] As a further description of the above technical solution:

[0012] The side wall of the rotating block is rotatably connected inside the fixed sleeve, and gear one meshes with gear two;

[0015] As a further description of the above technical solution:

[0016] A card block is fixedly connected to the side wall of the upper card sleeve, and one side wall of the card block is slidably connected inside the slot.

[0017] As a further description of the above technical solution:

[0019] As a further description of the above technical solution:

[0020] A fixing ring is fixedly connected to the side wall of the slide rod, and a spring is sleeved on the side wall of the slide rod;

[0021] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the starting motor drives the rotating block to rotate, thereby causing the connecting block to rotate around the rotating block. Through the meshing relationship between gear one and gear two, gear two rotates around gear one, thereby causing the stirring rod to rotate to achieve a stirring effect, increasing the mass transfer area, accelerating the escape of gas from the liquid, and solving the problem that in some gas-liquid separation devices, gas is often dispersed in the form of tiny bubbles inside the liquid, resulting in the gas not escaping from the liquid evenly and quickly, and a large amount of incompletely separated gas-liquid mixture flowing into subsequent reaction equipment, thereby reducing reaction efficiency. The above structure improves the overall separation efficiency.

[0025] 2. In this utility model, by pulling the handle and causing the slide rod to slide, the fixing ring squeezes the spring, causing the second locking block to disengage from the first locking block and releasing the fixing effect. At this time, by pulling the upper sleeve outward, the first locking block can be slid out of the slot, and then the upper and lower sleeves can be removed, making it easy to remove the filter screen for cleaning, ensuring the filtration performance of the filter screen, and avoiding the impact of impurities on the gas discharge efficiency.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-2 This utility model provides an embodiment of a gas-liquid separation device, comprising a separation tank 1, a support 2 fixedly connected to the side wall of the separation tank 1, a top plate 3 provided on the upper surface of the separation tank 1, a liquid inlet pipe 4 fixedly connected inside the top plate 3, an air outlet pipe 5 fixedly connected to the side wall of the separation tank 1, a filter screen 18 provided on the side wall of the air outlet pipe 5, a liquid outlet pipe 6 fixedly connected to the bottom of the separation tank 1, a stirring assembly provided on the lower surface of the top plate 3, and a fixing assembly provided on the side wall of the air outlet pipe 5; the stirring assembly includes a rotating rod 13 and a stirring rod 14, and the top plate 3... A motor 7 is fixedly connected to the upper surface, and a rotating block 9 is fixedly connected to the output end of the motor 7. A fixed sleeve 8 is fixedly connected inside the top plate 3. A gear 10 is fixedly connected to the side wall of the fixed sleeve 8. A connecting block 11 is fixedly connected to the side wall of the rotating block 9. The side wall of the rotating rod 13 is rotatably connected to the inside of the connecting block 11. A gear 2 12 is fixedly connected to the side wall of the rotating rod 13. The upper surface of the stirring rod 14 is fixedly connected to the lower surface of the rotating rod 13. The side wall of the rotating block 9 is rotatably connected to the inside of the fixed sleeve 8. Gear 10 and gear 2 12 mesh with each other.

[0034] When the device is in operation, the gas-liquid mixture enters the separation tank 1 through the inlet pipe 4. Then, the motor 7 is started, which drives the rotating block 9 to rotate. When the rotating block 9 rotates, it drives the connecting block 11 to rotate around it. The connecting block 11 transmits the circumferential motion of the rotating block 9 to the rotating rod 13, causing the rotating rod 13 to revolve around the rotating block 9 under the drive of the connecting block 11. At the same time, due to the meshing relationship between gear 10 and gear 2 12, the rotating rod 13 will rotate on its own axis. The rotating rod 13 generates a rotational motion while revolving around the rotating block, causing the stirring rod 14 to move together with the rotating rod 13, stirring the gas-liquid mixture in the separation tank 1. The stirring rod 14, through its own rotation, creates fluid disturbance in the separation tank 1, which can break the stability of bubbles in the liquid, promote the collision and aggregation of tiny bubbles, accelerate the escape of gas from the liquid, and significantly improve the gas-liquid separation efficiency. The separated gas passes through the filter screen 18 and is discharged through the gas outlet pipe 5. The separated liquid, under the action of gravity, is discharged from the liquid outlet pipe 6 by opening the valve on the side wall of the liquid outlet pipe 6, completing the entire gas-liquid separation process.

[0035] Reference Figures 3-4The fixing components include a lower retaining sleeve 15 and an upper retaining sleeve 16. The lower retaining sleeve 15 and the upper retaining sleeve 16 are fitted to the side walls of the air outlet pipe 5 and the filter screen 18. A fixing block 19 is fixedly connected to the side wall of the lower retaining sleeve 15. A slot 20 is opened inside the fixing block 19. A first retaining block 17 is fixedly connected to the side wall of the upper retaining sleeve 16. The side wall of the first retaining block 17 is slidably connected inside the slot 20. A sliding rod 21 is slidably connected inside the fixing block 19. A handle 22 is fixedly connected to one end of the sliding rod 21. A second retaining block 25 is fixedly connected to the other end of the sliding rod 21. The side wall of the second retaining block 25 is slidably connected inside the slot 20. The side wall of the second retaining block 25 is slidably connected inside the first retaining block 17. A fixing ring 24 is fixedly connected to the side wall of the sliding rod 21. A spring 23 is sleeved on the side wall of the sliding rod 21. One end of the spring 23 is fixedly connected inside the fixing block 19. The other end of the spring 23 is fixedly connected to the side wall of the fixing ring 24.

[0036] When the filter screen 18 needs to be disassembled and cleaned, pull the handle 22, causing the slide rod 21 to slide outward. Under the action of the handle 22, the slide rod 21 transmits the pulling force to the fixing ring 24, causing the fixing ring 24 to slide and compress the spring 23. Under the compression of the fixing ring 24, the spring 23 stores elastic potential energy. The spring 23 plays a key role in buffering and automatic reset here. When the external force disappears, it can push the fixing ring 24 and other components back to their initial position by its own elasticity. When the filter screen 18 is disassembled, the spring 23 is compressed, causing the second locking block 25 to change position under the action of the fixing ring 24. As the spring 23 is compressed, the second locking block 25 disengages from the first locking block. Inside 17, the fixing effect is released. The first clamp 17 and the second clamp 25 cooperate with each other and are originally in an interlocking state, which fixes the filter screen 18. When the second clamp 25 is disengaged from the inside of the first clamp 17, the upper clamp 16 is pushed upward. The upper clamp 16 and the lower clamp 15 fit tightly together during normal operation, clamping and fixing the filter screen 18 from both the top and bottom, ensuring the installation stability of the filter screen 18. When the upper clamp 16 is pushed upward, the connection between it and the lower clamp 15 is released, which makes it easier to disassemble the filter screen 18 for maintenance and cleaning, ensuring that the filter screen 18 can be cleaned in a timely manner and maintaining the good filtration and gas-liquid separation performance of the equipment.

[0037] Working principle: When the equipment is in operation, the gas-liquid mixture enters the separation tank 1 through the inlet pipe 4. Then, the motor 7 is started, driving the rotating block 9 to rotate. As the rotating block 9 rotates, the connecting block 11 rotates around it, causing the rotating rod 13 to revolve around the rotating block 9 under the influence of the connecting block 11. Simultaneously, due to the meshing relationship between gear 10 and gear 12, the rotating rod 13 will rotate on its own axis. The stirring rod 14, fixedly connected to the lower surface of the rotating rod 13, moves along with the rotating rod 13, stirring the gas-liquid mixture in the separation tank 1, accelerating the escape of gas from the liquid, and improving the gas-liquid separation efficiency. The separated gas is discharged through the gas outlet pipe 5. A filter screen 18 is installed on the side wall of the trachea 5 to filter out tiny droplets or impurities that may be carried in the gas, ensuring the purity of the discharged gas. When the filter screen 18 needs to be disassembled and cleaned, pull the handle 22 to make it slide the slide rod 21 outward, thereby allowing the fixing ring 24 to slide and squeeze the spring 23, causing the second locking block 25 to disengage from the first locking block 17 and releasing the fixing effect. At this time, by pushing the upper locking sleeve 16 upward, the fixing effect between the upper locking sleeve 16 and the lower locking sleeve 15 is released, making it easier to disassemble the filter screen 18 for maintenance and cleaning. The separated liquid is discharged from the liquid outlet pipe 6 fixedly connected to the bottom of the separation tank 1 under the action of gravity, completing the entire gas-liquid separation process.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
