Description

Technical Field

[0001] The utility model relates to the technical field of distillation columns, and particularly relates to a liquid distribution device for a distillation column. Background Technique

[0002] In the field of chemical production, distillation is an important separation and purification technology, and the performance of a distillation column depends to a large extent on the distribution effect of the liquid inside it.

[0003] In actual applications, the existing liquid distribution devices for distillation columns have complex structures, high manufacturing and maintenance costs; there are also some devices that cannot precisely control the flow and distribution of liquids, resulting in uneven gas-liquid contact and affecting the distillation efficiency and product quality.

[0004] Therefore, we propose a liquid distribution device for a distillation column. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a liquid distribution device for a distillation column, in order to prevent the complex structure of the liquid distribution device, high manufacturing and maintenance costs; there are also some devices that cannot precisely control the flow and distribution of liquids, resulting in uneven gas-liquid contact and affecting the distillation efficiency and product quality, so as to improve the performance of the distillation column, enhance the accuracy of liquid distribution, improve the uniformity of gas-liquid contact, optimize the distillation efficiency and ensure the product quality, and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A liquid distribution device for a distillation column includes a distillation column body. The upper part of the inner wall of the distillation column body is rotatably connected with a threaded rod. Two sets of relatively output threaded grooves are arranged outside the threaded rod. Two sliders are threadedly connected to the outside of the two sets of threaded grooves. Both ends of the two sliders are rotatably connected with connecting rods, and the connecting rods are arranged oppositely. The inner sides of two adjacent connecting rods are rotatably connected with a connecting block. The bottom end of the connecting block is fixedly connected with a moving plate. The bottom end of the moving plate is provided with a plurality of uniformly distributed pull rods. An installation groove is opened at the bottom end of the pull rod. A plurality of second grooves are annularly arranged inside the installation groove. A horizontally arranged second spring is fixedly installed inside the second groove. One end of the second spring is fixedly installed with a second limiting ball;

[0008] A cylinder is arranged directly below the moving plate. A liquid inlet pipe is connected to the outer wall of the cylinder. The other end of the liquid inlet pipe penetrates through the distillation column body and extends to the outside. A liquid storage tank is arranged inside the cylinder, and the liquid storage tank is communicated with the liquid inlet pipe. A plurality of vertically arranged liquid outlet openings are annularly arranged on the inner wall of the cylinder, and the liquid outlet openings are communicated with the liquid storage tank;

[0009] The bottom end of the cylinder is provided with drainage grooves whose number is equal to the number and distribution position of the pull rods, and the upper part of the inner wall of the drainage groove is fixedly connected to a second annular magnet, and the interior of the drainage groove is slidably connected to a valve body, and the valve body includes a first annular magnet that is attracted to the second annular magnet in a special shape, and the top annular array of the first annular magnet has multiple groups of vertically arranged connecting plates, and the top of the connecting plate is fixedly connected to a valve plate, and the valve plate matches the mounting groove, and the outer side of the valve plate is provided with a first limiting groove that matches the second limiting ball.

[0010] By adopting the above technical solution, in the distillation tower body, when the threaded rod rotates, because two sets of relatively output thread grooves are provided on its outside, the two sets of sliders threadedly connected thereto move toward or away from each other along the threaded rod. When the two sets of sliders move, the connecting rods rotatably connected at both ends thereof will move accordingly. Since the connecting rods are relatively arranged and rotatably connected with the connecting blocks, the movement of the adjacent connecting rods will push or pull the connecting blocks, thereby allowing the connecting blocks to drive the moving plate to rise or fall. The second spring and the second limiting ball arranged laterally in the second groove play the role of positioning and matching connection. When subjected to external force, the second spring will expand and contract, causing the second limiting ball to move in the second groove.

[0011] The liquid enters the liquid storage tank in the cylinder through the liquid inlet pipe. The liquid storage tank plays the role of storing and buffering the liquid. Since the liquid storage tank is connected with multiple groups of vertically arranged liquid outlets in the annular array, when the liquid in the liquid storage tank reaches a certain liquid level, the liquid will flow out evenly from each liquid outlet, thereby achieving uniform distribution of the liquid and a specific flow pattern, which is conducive to achieving a more efficient and uniform material exchange and separation process in the distillation tower body;

[0012] When the movable plate drives the pull rod to move upward, the second limiting ball at the bottom of the pull rod will cooperate with the first limiting groove on the outside of the valve plate, and the valve plate matches the mounting groove, which plays a role in limiting and positioning the position of the valve plate, ensuring the stability and controllability of the discharge process, so that the valve body is moved upward. Since the second annular magnet on the upper inner wall of the discharge groove and the first annular magnet in the valve body are attracted to each other in a special way, when the second limiting ball is separated from the first limiting groove on the outside of the valve plate, the discharge channel originally blocked by the valve plate is opened, and the liquid is discharged.

[0013] Furthermore, a motor is fixedly mounted on the outer wall of the distillation tower body close to the threaded rod, and an output shaft at one end of the motor passes through the distillation tower body and is fixedly connected to the threaded rod.

[0014] By adopting the above technical solution, when the motor is working, the output shaft at one end thereof rotates, and the rotation of the motor drives the threaded rod to rotate, thereby providing a power basis.

[0015] Furthermore, a plurality of groups of moving blocks which are arranged at equal intervals in a circular array on the upper part of the outer side of the moving plate and are in contact with the rectification tower body are provided.

[0016] By adopting the above technical solution, during the movement of the moving plate, a plurality of groups of moving blocks in the circular array on the upper part of its outer side will slide along the inner wall of the rectification tower body. On the one hand, these moving blocks can enhance the stability of the movement of the moving plate, reduce its shaking or deviation, and ensure the normal operation of the system.

[0017] Furthermore, a plurality of first grooves equal in number to the liquid outlets are formed in the middle of the outer side of the moving plate, and first springs are fixedly installed inside the first grooves.

[0018] By adopting the above technical solution, during the operation of the device, when the moving plate moves to a specific position, the first limiting ball will correspond to the liquid outlet. Since the first spring is fixedly installed in the first groove and one end of it is connected to the first limiting ball, the first spring can provide a certain elastic force.

[0019] Furthermore, a first limiting ball is fixedly installed at one end of the first spring, and the first limiting ball is matched with the liquid outlet.

[0020] By adopting the above technical solution, when the first limiting ball contacts the liquid outlet, the elastic force of the first spring can make the first limiting ball closely fit the liquid outlet, playing a role in restricting or regulating the outflow of liquid from the liquid outlet, so as to achieve precise control and regulation of the liquid flow.

[0021] Furthermore, a plurality of groups of support rods arranged at equal intervals are provided in a circular array on the outside of the cylinder body, and the ends of the support rods far away from the cylinder body are fixedly connected to the inner wall of the rectification tower body.

[0022] By adopting the above technical solution, through a plurality of groups of support rods arranged at equal intervals in a circular array, the cylinder body is stably supported at a specific position inside the rectification tower body. The support rods play a role in bearing the weight of the cylinder body and various forces and vibrations that may occur during the working process, ensuring that the position of the cylinder body remains fixed, thereby guaranteeing the structural stability and operation reliability of the entire device.

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] (1) For the liquid distribution device of a rectification tower of the utility model, liquid enters the liquid storage tank through the liquid inlet pipe, and the liquid storage tank is communicated with the liquid outlets in a circular array. When the liquid level reaches a certain degree, the liquid can flow out evenly from each liquid outlet, realizing the uniform distribution of the liquid, promoting more efficient and uniform mass exchange and separation, and improving the rectification efficiency and product quality.

Detailed Embodiment

[0033] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0034] To prevent the complex structure of the liquid distribution device, high manufacturing and maintenance costs; and there are also some devices that cannot precisely control the flow and distribution of liquids, resulting in uneven gas-liquid contact, affecting the rectification efficiency and product quality. Therefore, to improve the performance of the rectification column, enhance the accuracy of liquid distribution, improve the uniformity of gas-liquid contact, optimize the rectification efficiency, and ensure product quality, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 shown, a liquid distribution device for a rectification column, including a rectification column body 1. The upper part of the inner wall of the rectification column body 1 is rotatably connected with a threaded rod 3. Two sets of relatively output threaded grooves 4 are arranged outside the threaded rod 3. Two sets of sliders 5 are threadedly connected to the outside of the two sets of threaded grooves 4. Both ends of the two sets of sliders 5 are rotatably connected with connecting rods 6, and the connecting rods 6 are arranged oppositely. The inner sides of two adjacent connecting rods 6 are rotatably connected with a connecting block 7. The bottom end of the connecting block 7 is fixedly connected with a moving plate 8. A plurality of uniformly distributed pull rods 12 are arranged at the bottom end of the moving plate 8. An installation groove is opened at the bottom end of the pull rod 12. A plurality of second grooves 13 are annularly arranged inside the installation groove. A horizontally arranged second spring 14 is fixedly installed inside the second groove 13. One end of the second spring 14 is fixedly installed with a second limiting ball 15;

[0035] A cylinder 16 is arranged directly below the moving plate 8. The outer wall of the cylinder 16 is connected with a liquid inlet pipe 17. The other end of the liquid inlet pipe 17 penetrates through the rectification column body 1 and extends to the outside. A liquid storage tank 18 is arranged inside the cylinder 16, and the liquid storage tank 18 is communicated with the liquid inlet pipe 17. A plurality of vertically arranged liquid outlet openings 19 are annularly arranged on the inner wall of the cylinder 16, and the liquid outlet openings 19 are communicated with the liquid storage tank 18;

[0036] A liquid discharge groove 28 equal in number and distribution position to the pull rod 12 is opened at the bottom end of the cylinder 16. The upper part of the inner wall of the liquid discharge groove 28 is fixedly connected with a second annular magnet 25. A valve body 20 is slidably connected inside the liquid discharge groove 28. The valve body 20 includes a first annular magnet 21 that is abnormally attracted to the second annular magnet 25. A plurality of vertically arranged connecting plates 22 are annularly arranged at the top end of the first annular magnet 21. The top end of the connecting plate 22 is fixedly connected with a valve plate 23, and the valve plate 23 is matched with the installation groove. A first limiting groove 24 matched with the second limiting ball 15 is arranged outside the valve plate 23.

[0037] During use, in the rectification tower body 1, when the threaded rod 3 rotates, due to the two sets of relatively output threaded grooves 4 provided on its outer side, the two sets of sliders 5 threadedly connected thereto move towards or away from each other along the threaded rod 3. When the two sets of sliders 5 move, the connecting rods 6 rotatably connected to their two ends will move accordingly. Since the connecting rods 6 are oppositely arranged and rotatably connected to the connecting block 7, the movement of the adjacent connecting rods 6 will push or pull the connecting block 7, and then the connecting block 7 drives the moving plate 8 to rise or fall. The laterally arranged second spring 14 and second limiting ball 15 in the second groove 13 play a role in positioning and mating connection. When subjected to an external force, the second spring 14 will expand and contract, causing the second limiting ball 15 to move within the second groove 13;

[0038] The liquid enters the liquid storage tank 18 in the cylinder body 16 through the liquid inlet pipe 17. The liquid storage tank 18 plays a role in storing and buffering the liquid. Since the liquid storage tank 18 is communicated with a plurality of vertically arranged liquid outlet ports 19 in an annular array, when the liquid in the liquid storage tank 18 reaches a certain liquid level, the liquid will flow out evenly from each liquid outlet port 19, so as to achieve the uniform distribution of the liquid and a specific flow pattern, thereby contributing to a more efficient and uniform mass exchange and separation process within the rectification tower body 1;

[0039] When the moving plate 8 drives the pull rod 12 to move upward, the second limiting ball 15 at the bottom end of the pull rod 12 will cooperate with the first limiting groove 24 on the outer side of the valve plate 23, and the valve plate 23 matches the installation groove, playing a role in restricting and positioning the position of the valve plate 23, ensuring the stability and controllability of the liquid discharge process, so that the valve body 20 is moved upward. Since the second annular magnet 25 on the upper part of the inner wall of the liquid discharge groove 28 is attracted to the first annular magnet 21 in the valve body 20 in a special shape, when the second limiting ball 15 disengages from the first limiting groove 24 on the outer side of the valve plate 23, the liquid discharge channel originally blocked by the valve plate 23 is opened, and the liquid can be discharged.

[0040] Exemplarily, as Figure 1 shown, the present invention further includes that a motor 2 is fixedly installed on the outer wall of the rectification tower body 1 close to the threaded rod 3, and the output shaft at one end of the motor 2 penetrates through the rectification tower body 1 and is fixedly connected to the threaded rod 3.

[0041] During use, when the motor 2 works, the output shaft at one end thereof rotates, and the rotation of the motor 2 drives the threaded rod 3 to rotate, thereby providing a power basis.

[0042] Exemplarily, as Figure 1 、 Figure 2 shown, the present invention further includes that a plurality of equally spaced moving blocks 26 that are arranged in an annular array on the upper part of the outer side of the moving plate 8 and are in contact with the rectification tower body 1.

[0043] During use, when the moving plate 8 is in motion, multiple groups of moving blocks 26 arranged in an annular array on its upper outer side will slide along the inner wall of the rectification tower body 1. On the one hand, these moving blocks 26 can enhance the stability of the movement of the moving plate 8, reduce its shaking or deviation, and ensure the normal operation of the system.

[0044] Exemplarily, as Figure 1 、 Figure 2 shown, the present invention further includes that a plurality of first grooves 9 equal in number to the number of liquid outlets 19 are formed in the middle of the outer side of the moving plate 8, and a first spring 10 is fixedly installed inside the first grooves 9.

[0045] During use, during the operation of the device, when the moving plate 8 moves to a specific position, the first limiting ball 11 will correspond to the liquid outlet 19. Since the first spring 10 is fixedly installed in the first groove 9 and one end thereof is connected to the first limiting ball 11, the first spring 10 can provide a certain elastic force.

[0046] Exemplarily, as Figure 1 、 Figure 2 、 Figure 4 shown, the present invention further includes that a first limiting ball 11 is fixedly installed at one end of the first spring 10, and the first limiting ball 11 is matched with the liquid outlet 19.

[0047] During use, when the first limiting ball 11 contacts the liquid outlet 19, the elastic force of the first spring 10 can make the first limiting ball 11 closely fit the liquid outlet 19, playing a role in restricting or regulating the flow of liquid from the liquid outlet 19, so as to achieve precise control and regulation of the liquid flow.

[0050] It should be noted that the present utility model is a liquid distribution device for a rectifying column. When the motor 2 operates, the rotation of its output shaft drives the threaded rod 3 to rotate. When the threaded rod 3 rotates, the two sets of relatively output threaded grooves 4 on its outer part cause the two sets of sliders 5 threadedly connected thereto to move towards or away from each other. The movement of the sliders 5 drives the connecting rods 6 rotatably connected at both ends thereof to move. The adjacent connecting rods 6 push or pull the connecting block 7, thereby driving the moving plate 8 to rise or fall; when the moving plate 8 drives the pull rod 12 to move upward, the second limit ball 15 at the bottom end of the pull rod 12 cooperates with the first limit groove 24 on the outer side of the valve plate 23 to limit and position the valve plate 23. When the second limit ball 15 disengages from the first limit groove 24, the liquid discharge channel is completely opened and the liquid can be discharged; at the same time, the liquid enters the liquid storage tank 18 in the cylinder body 16 through the liquid inlet pipe 17 for storage and buffering. When the liquid in the liquid storage tank 18 reaches a certain liquid level and the moving plate 8 moves to a specific position, the first limit ball 11 corresponds to the liquid outlet 19, and the elastic force of the first spring 10 causes the first limit ball 11 to closely fit the liquid outlet 19 to limit or regulate the uniform outflow of the liquid from the liquid outlet 19, realizing the uniform distribution of the liquid and a specific flow pattern; during the movement of the moving plate 8, the moving block 26 on the upper part of its outer side slides along the inner wall of the rectifying column body 1, enhancing the stability of the movement of the moving plate 8. The cylinder body 16 is stably supported at a specific position inside the rectifying column body 1 by a plurality of groups of equally spaced support rods 27 arranged in an external annular array, ensuring reliable operation.
