Description

Technical Field

[0001] This utility model relates to the technical field of hydrocyclone separation equipment, and in particular to a gas-liquid track-type hydrocyclone separation equipment. Background Technology

[0002] "Gas-liquid track-type" refers to a process in which gas and liquid flow along specific tracks or paths to achieve more efficient separation. This design guides the gas and liquid phases to move along different paths, utilizing centrifugal force and the difference in flow trajectories to cause the denser liquid to be thrown to the outside, while the less dense gas accumulates in the central region, thus achieving effective separation.

[0003] Chinese utility model patent with publication number CN222445997U discloses a tail gas treatment device for water washing absorption and hydrocyclone separation. The hydrocyclone separation device includes a water washing tank and a hydrocyclone separator. An air inlet pipe is provided on the upper surface of the water washing tank. A connecting pipe is fixedly connected to one end of the air inlet pipe. A diverter pipe is fixedly connected to the side surface of the connecting pipe. A motor is fixedly connected to the lower surface of the water washing tank. A connecting shaft is fixedly connected to the output end of the motor. An inner box is fixedly connected to the end of the connecting shaft away from the motor. A fixing rod is fixedly connected to the inner side wall of the inner box. A conical tip is fixedly connected to the outer surface of the fixing rod. The diverter pipe can deliver the tail gas to different positions, increasing the contact range between the tail gas and the reaction liquid. At the same time, the motor drives the connecting shaft to rotate, causing the inner box to rotate, thereby improving the reaction absorption effect and reaction effect of the tail gas and the reaction liquid.

[0004] The existing hydrocyclone separators mentioned above only have a bottom-mounted liquid discharge pipe, so they cannot separate the discharged liquid again, especially the recyclable liquid in the discharged wastewater, which is not conducive to the subsequent specialized treatment of different liquids. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a gas-liquid track-type hydrocyclone separator that can further separate liquids after gas-liquid separation, which is beneficial for specializing in the processing of different liquids and improving work efficiency.

[0006] This utility model discloses a gas-liquid track-type hydrocyclone separator, comprising a main body, a guide pipe, and an exhaust pipe. The upper part of the main body is equipped with an inlet cylinder, and the lower part is a hydrocyclone cone. A separation chamber is located inside the main body, and an outlet is located at the bottom of the hydrocyclone cone. The guide pipe is installed on the side wall of the inlet cylinder and communicates with the separation chamber. The exhaust pipe is installed at the center of the top of the inlet cylinder and communicates with the separation chamber. It also includes a lower collection tank, an inner outlet pipe, a funnel, and a pusher cylinder. The lower collection tank is installed at the bottom of the main body. The main body has an outlet port that connects to the interior of the lower collection tank. An outlet pipe is installed on the lower collection tank. The upper part of the inner outlet pipe concentrically passes through the lower collection tank and the main body's inlet, extending into the bottom of the main body's separation chamber. An outwardly expanding funnel is installed at the upper end of the funnel. The lower end of the inner outlet pipe extends below the lower collection tank. The fixed end of the push cylinder is installed on the lower collection tank, and the piston rod of the push cylinder is connected to the inner outlet pipe. During operation, the guide pipe is tangent to the main body's inlet cylinder and connects to an external liquid pipeline. A mixture of liquid and gas is transported in the main body pipeline. The mixture is input into the separation chamber of the main body through the guide pipe and flows downward along the inner wall in a rotating manner. The mixture gradually separates into liquid and gas. The gas accumulates in the middle of the separation chamber of the main body's swirling cone and rises before being discharged through the exhaust pipe. The remaining mixture continues to swirl downward and separate, so that the denser liquid in the outer layer enters the lower collection tank through outlet one and is discharged through outlet two, while the less dense liquid in the inner layer enters the inner outlet pipe through the funnel and is discharged. The piston rod of push cylinder one extends and retracts, driving the inner outlet pipe to rise and fall, thereby adjusting the separation ratio of the two liquids. When push cylinder one drives the inner outlet pipe to fall so that the edge of the funnel contacts the inner wall of the main body's swirling cone, only the inner outlet pipe is open to discharge liquid, realizing two working states. Compared with the existing technology, it can separate the liquid again after gas-liquid separation, thereby separating the recyclable liquid from the discharged wastewater, which is beneficial for subsequent specialized treatment of different liquids and improves work efficiency.

[0007] Preferably, it also includes a gradient tube, the guide tube is a square tube, and the output end of the guide tube gradually expands. The output end of the gradient tube is connected to the input end of the guide tube. The gradient tube gradually transitions from a round tube to a square tube from the input end to the output end. The input end of the gradient tube is connected to an external liquid pipeline. By installing the gradient tube, the cross-section of the mixture can be gradually changed and adapted to the guide tube, reducing the impact on the guide tube.

[0008] Preferably, it also includes an air pump, the inlet of which is connected to the upper port of the exhaust pipe; the operation of the air pump accelerates the discharge of gas from the exhaust pipe, thereby improving the gas discharge efficiency.

[0009] Preferably, it also includes a second pusher cylinder and a connecting plate. The lower end of the exhaust pipe extends into the interior of the liquid-swirling cone of the main body. The fixed end of the second pusher cylinder is installed on the main body. The piston rod of the second pusher cylinder is connected to the exhaust pipe through the connecting plate. The extension and retraction of the piston rod of the second pusher cylinder drives the exhaust pipe to rise and fall through the connecting plate, thereby adjusting the position of the lower end of the exhaust pipe to adapt to the gas accumulation positions at different heights in the separation chamber of the main body, thus having good versatility.

[0010] Preferably, it also includes an elastic support rod and a buffer pad. The elastic support rod is installed at the lower end of the exhaust pipe, and the buffer pad is installed on the lower end of the elastic support rod. The buffer pad is arranged opposite to the funnel. By setting the elastic support rod and the buffer pad, the exhaust pipe is prevented from colliding and being damaged by the funnel.

[0011] Preferably, the system also includes two valve tubes, two piston plates, two base plates, and two springs. The two valve tubes are mounted opposite each other on the side wall of the exhaust pipe, and are located inside the exhaust pipe. Each valve tube has a vent hole on its outer wall. The two piston plates are slidably mounted in the two valve tubes, and wear-resistant sealing rings are provided between the piston plates and the interior of the two valve tubes. The two base plates are mounted on the inner ends of the two valve tubes. The outer ends of the two springs are connected to the two piston plates, and the inner ends of the two springs are connected to the two base plates. The two piston plates seal the vent holes of the two valve tubes. When the air pressure in the upper part of the separation chamber of the main body is within the normal range, the elastic force of the two springs causes the two piston plates to seal the vent holes of the two valve tubes. At this time, the residual gas in the upper part of the separation chamber of the main body will not enter the exhaust pipe. When the air pressure in the upper part of the separation chamber of the main body is higher than the normal range, the residual gas in the upper part of the separation chamber of the main body pushes the two piston plates inward, causing the vent holes of the two valve tubes to open, allowing the residual gas to enter the exhaust pipe and be discharged, thus achieving passive pressure relief.

[0012] Preferably, the device also includes two racks, a motor, and a gear. The two racks are respectively mounted on the inner walls of the two piston plates and are arranged opposite each other. The motor is mounted on the two valve pipes via a bracket. The output shaft of the motor is concentrically mounted with a gear that meshes with the two racks. The motor drives the gear to rotate, and the gear simultaneously meshes with the two racks, thereby driving the two racks to move synchronously relative to each other. This causes the two racks to drive the two piston plates to move along the two valve pipes, thereby actively opening or closing the vent holes of the two valve pipes to achieve active pressure relief.

[0013] Compared with the prior art, the beneficial effects of this utility model are: it can separate the liquid again after gas-liquid separation, thereby separating the recyclable liquid from the discharged sewage, which is conducive to the subsequent special treatment of different liquids and improves work efficiency.

[0016] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0017] like Figures 1 to 4As shown, a gas-liquid track-type hydrocyclone separator includes a main body 1, a guide pipe 2, and an exhaust pipe 3. The upper part of the main body 1 is equipped with an inlet cylinder, and the lower part is a hydrocyclone cone. A separation chamber is located inside the main body 1. An outlet is located at the bottom of the hydrocyclone cone. The guide pipe 2 is installed on the side wall of the inlet cylinder and communicates with the separation chamber. The exhaust pipe 3 is installed at the center of the top of the inlet cylinder of the main body 1 and communicates with the separation chamber. The separator also includes a lower collection tank 4, an inner outlet pipe 5, a funnel 6, and a pusher cylinder 7. The lower collection tank 4 is installed at the bottom of the main body 1. The outlet of the main body 1 communicates with the interior of the lower collection tank 4. An outlet pipe 2 is installed on the lower collection tank 4. The upper part of the inner outlet pipe 5 concentrically passes through the lower collection tank 4 and the inlet of the main body 1 and extends into the bottom of the separation chamber of the main body 1. The upper end of the funnel 6 is an outwardly expanding funnel. The lower end of the inner outlet pipe 5 extends out of the lower collection tank. Below the box 4, the fixed end of push cylinder 7 is installed on the lower liquid collection box 4, and the piston rod of push cylinder 7 is connected to the inner liquid outlet pipe 5; it also includes a gradient pipe 8, the guide pipe 2 is a square pipe, and the output end of the guide pipe 2 gradually expands. The output end of the gradient pipe 8 is connected to the input end of the guide pipe 2. The input end of the gradient pipe 8 gradually transitions from a round pipe to a square pipe from the output end; it also includes an air pump 9, the inlet of which is connected to the upper port of the exhaust pipe 3; it also includes a push cylinder 10 and a connecting plate 11. The lower end of the exhaust pipe 3 extends into the swirling cone of the main body 1. The fixed end of push cylinder 10 is installed on the main body 1. The piston rod of push cylinder 10 is connected to the exhaust pipe 3 through the connecting plate 11; it also includes an elastic support rod 12 and a buffer pad 13. The lower port of the exhaust pipe 3 is equipped with the elastic support rod 12, and the buffer pad 13 is installed on the lower end of the elastic support rod 12. The buffer pad 13 is arranged opposite to the funnel 6.

[0018] The input end of the gradient tube 8 is connected to an external liquid pipeline. By installing the gradient tube 8, the cross-section of the mixture can be gradually changed and adapted to the guide tube 2, reducing the impact on the guide tube 2. During operation, the piston rod of the push cylinder 10 extends and retracts, driving the exhaust pipe 3 to rise and fall through the connecting plate 11, thereby adjusting the position of the lower end of the exhaust pipe 3 to adapt to the gas accumulation positions at different heights in the separation chamber of the main body 1. Buffering is achieved by setting an elastic support rod 12 and a buffer pad 13 to prevent the exhaust pipe 3 from colliding and being damaged by the funnel 6. The guide tube 2 is tangent to the liquid inlet cylinder of the main body 1 and is connected to an external liquid pipeline. The liquid pipeline transports a mixture of liquid and gas. The mixture is input into the separation chamber of the main body 1 through the guide tube 2 and flows downwards along the inner wall in a rotating manner. The mixture gradually undergoes gas-liquid separation, and the gas accumulates in the middle of the separation chamber of the swirling cone of the main body 1. After rising, the liquid is discharged through exhaust pipe 3. The air pump 9 accelerates the discharge of gas from exhaust pipe 3. The remaining mixture continues to swirl downwards and separate, allowing the denser liquid in the outer layer to enter the lower collection tank 4 through outlet 1 and then be discharged through outlet pipe 2. The less dense liquid in the inner layer enters the inner outlet pipe 5 through funnel 6 and is discharged. The piston rod of push cylinder 7 extends and retracts, driving the inner outlet pipe 5 to rise and fall, thereby adjusting the separation ratio of the two liquids. When push cylinder 7 drives the inner outlet pipe 5 to descend, causing the edge of funnel 6 to contact the inner wall of the swirling cone of the main body 1, only the inner outlet pipe 5 is left to discharge liquid, achieving two working states. Compared with the existing technology, it can separate the liquid again after gas-liquid separation, thereby separating the recyclable liquid from the discharged wastewater, which is beneficial for subsequent specialized treatment of different liquids and improves work efficiency. Example 2

[0019] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, based on Embodiment 1, it further includes two valve tubes 14, two piston plates 15, two base plates 16, and two springs 17. The two valve tubes 14 are mounted opposite each other on the side wall of the exhaust pipe 3, and are located inside the exhaust pipe 3. Vent holes are provided on the outer walls of both valve tubes 14. The two piston plates 15 are slidably mounted in the two valve tubes 14 respectively. Wear-resistant sealing rings are provided between the two piston plates 15 and the interior of the two valve tubes 14. The two base plates 16 are respectively mounted on the inner ends of the two valve tubes 14. The outer ends of the two springs 17 are connected to the two piston plates 15 respectively, and the inner ends of the two springs 17 are connected to the two base plates 16 respectively. The two piston plates 15 respectively seal the vent holes of the two valve pipes 14. It also includes two racks 18, a motor 19 and a gear 20. The two racks 18 are respectively installed on the inner walls of the two piston plates 15 and are arranged opposite to each other. The motor 19 is installed on the two valve pipes 14 through a bracket. The output shaft of the motor 19 is concentrically mounted with the gear 20, and the gear 20 meshes with the two racks 18.

[0020] When the air pressure in the upper part of the separation chamber of the main body 1 is within the normal range, the elastic force of the two springs 17 causes the two piston plates 15 to close the vent holes of the two valve pipes 14. At this time, the residual gas in the upper part of the separation chamber of the main body 1 will not enter the exhaust pipe 3. When the air pressure in the upper part of the separation chamber of the main body 1 is higher than the normal range, the residual gas in the upper part of the separation chamber of the main body 1 pushes the two piston plates 15 inward, causing the vent holes of the two valve pipes 14 to open, allowing the residual gas to enter the exhaust pipe 3 and be discharged, thus achieving passive pressure relief. The motor 19 drives the gear 20 to rotate, and the gear 20 simultaneously meshes with the two racks 18, thereby driving the two racks 18 to move synchronously relative to each other. This causes the two racks 18 to drive the two piston plates 15 to move along the two valve pipes 14, thereby actively opening or closing the vent holes of the two valve pipes 14, thus achieving active pressure relief.

[0021] like Figures 1 to 6As shown, this utility model discloses a gas-liquid track-type hydrocyclone separator. During operation, a mixture of liquid and gas is first transported through a liquid pipeline. The mixture is then fed into the separation chamber of the main body 1 via a guide pipe 2 and flows downwards along the inner wall in a rotating manner. Gradually, the mixture undergoes gas-liquid separation. The gas accumulates in the middle of the separation chamber of the hydrocyclone cone in the main body 1, rises, and is discharged through an exhaust pipe 3. The remaining mixture continues to swirl downwards and separate further. The denser liquid in the outer layer enters the lower collection tank 4 through outlet 1 and is discharged through outlet pipe 2. The less dense liquid in the inner layer enters the inner outlet pipe 5 through a funnel 6 and is discharged. Then, the piston rod of push cylinder 7 extends and retracts, driving the inner outlet pipe 5 to rise and fall, thereby adjusting the separation ratio of the two liquids. When push cylinder 7 drives the inner outlet pipe 5 to descend, the funnel... When the edge of 6 contacts the inner wall of the liquid-swirl cone of the main body 1, only the inner liquid outlet pipe 5 is left to discharge liquid, realizing two working states; finally, when the air pressure in the upper part of the separation chamber of the main body 1 is within the normal range, the elastic force of the two springs 17 causes the two piston plates 15 to close the vent holes of the two valve pipes 14. At this time, the residual gas in the upper part of the separation chamber of the main body 1 will not enter the exhaust pipe 3. When the air pressure in the upper part of the separation chamber of the main body 1 is higher than the normal range, the motor 19 drives the gear 20 to rotate. The gear 20 simultaneously meshes with the two racks 18, thereby driving the two racks 18 to move synchronously relative to each other. This causes the two racks 18 to drive the two piston plates 15 to move along the two valve pipes 14, thereby actively opening the vent holes of the two valve pipes 14, allowing the residual gas to enter the exhaust pipe 3 and be discharged, thus realizing active pressure relief.

[0022] The main functions achieved by this utility model are: 1. It can separate the liquid after gas-liquid separation, thereby separating the recyclable liquid from the discharged wastewater, which is beneficial for subsequent specialized treatment of different liquids and improves work efficiency. 2. The operation of air pump 9 accelerates the discharge of gas from exhaust pipe 3, improving the gas discharge efficiency; 3. The position of the lower end of the exhaust pipe 3 can be adjusted to adapt to different gas accumulation positions in the separation chamber of the main body 1, and it has good versatility; 4. The residual gas is discharged into the exhaust pipe 3 through the pressure relief mechanism, realizing both active and passive pressure relief.

[0023] The gas-liquid track-type hydrocyclone separator of this utility model uses common mechanical methods for installation, connection, or setup, and can be implemented as long as it achieves the beneficial effect. The main body 1, guide pipe 2, exhaust pipe 3, push cylinder 1 7, gradient pipe 8, air pump 9, push cylinder 2 10, elastic support rod 12, buffer pad 13, piston plate 15, spring 17, rack 18, motor 19, and gear 20 of the gas-liquid track-type hydrocyclone separator of this utility model are purchased from the market.
