[0002] In chemical production processes, especially fine chemical production, in order to ensure uniform liquid distribution, most processes use a main and auxiliary distributor. The feed pipe feeds liquid into the main distributor, and the main distributor distributes the liquid to the downstream auxiliary distributor through the distribution hole, so that the liquid is evenly distributed on the surface of the packing.

[0003] In existing technology, a buffer plate is installed below the dispensing slot of the dispenser to buffer the falling speed of the liquid, thereby ensuring the dispensing effect.

[0004] However, in actual use, since the main body of the distribution device is tubular, when the liquid enters the distribution tube, the liquid will first flow out through the outlet in the middle of the distribution tube. Only after the liquid fills both sides of the distribution tube will it flow out through the outlets at both ends, resulting in uneven distribution. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-efficiency distillation column distributor, which solves the problem that, in actual use, because the main body of the distribution device is tubular, when liquid enters the distribution tube, the liquid first flows out through the outlet in the middle of the distribution tube, and only after the two sides of the distribution tube are filled with liquid does it flow out through the outlets at both ends, resulting in uneven distribution.

[0007] Preferably, the discharge device includes a baffle plate, which is rotatably connected to the inner wall of the diverter block via a sealed bearing; a gear is fixedly connected to one end of the baffle plate extending to the outer wall of the diverter block; a belt is meshed with the outer wall of the gear; a second servo motor is fixedly connected to the outer wall of the fixed housing, and one end of its output end extending into the interior of the fixed housing is fixedly connected to the outer wall of the gear; wherein, through the cooperation of the gear and the belt, the second servo motor drives the baffle plate to rotate.

[0008] Preferably, the inside of the diversion block is provided with several accumulation cavities.

[0009] Preferably, the top of the distribution box is connected to a connecting pipe, and a filter device is installed on the top of the connecting pipe.

[0011] Beneficial effects

[0012] This invention provides a high-efficiency distillation column distributor. It offers the following advantages: Through the cooperation of a bidirectional auger, a first servo motor, and a distribution pipe, when liquid enters the distribution tank, the first servo motor drives the bidirectional auger to rotate, causing the liquid to flow evenly within the tank.

Detailed Implementation

[0020] 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.

[0021] In actual use, since the main body of the distribution device is tubular, when the liquid enters the distribution tube, the liquid will first flow out through the outlet in the middle of the distribution tube. Only after the liquid fills both sides of the distribution tube will it flow out through the outlets at both ends, resulting in uneven distribution.

[0022] In view of this, the present invention provides a high-efficiency distillation column distributor, which solves the problem that in actual use, because the main body of the distribution device is tubular, when liquid enters the distribution tube, the liquid will first flow out through the outlet in the middle of the distribution tube, and only after the two sides of the distribution tube are filled with liquid will it flow out through the outlets at both ends, resulting in uneven distribution.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example 1: By Figure 1-5It is known that a high-efficiency distillation column distributor includes a distribution box 1, a fixed shell 12 fixedly connected to the bottom of the distribution box 1, a flow divider 13 fixedly connected to the top of the inner wall of the fixed shell 12, and a flow divider 2 installed inside the fixed shell 12. The flow divider 2 includes a bidirectional auger 21, a first servo motor 22, a flow divider pipe 23, a discharge device 24, and a water divider plate 25. The bidirectional auger 21 is rotatably connected to the upper inner wall of the distribution box 1 through a sealed bearing; the first servo motor 22 is fixedly connected to the outer wall of the distribution box 1, and its output end is fixedly connected to one end of the bidirectional auger 21 extending to the outside of the distribution box 1; several flow divider pipes 23 are provided, each equipped with a flow divider. The device is installed between the fixed housing 12 and the distribution box 1; the discharge device 24 is installed inside the diversion block 13; the water distribution plate 25 is fixed to the inner wall of the distribution box 1 and is located below the bidirectional auger 21, and has drainage holes that are respectively connected to the top of each diversion pipe 23; wherein, through the cooperation of the bidirectional auger 21 and the first servo motor 22, the liquid flows into the diversion block 13 through the diversion pipe 23, the discharge device 24 opens the diversion block 13, and the water distribution plate 25 supports the diversion pipe 23; wherein the model of the first servo motor 22 is not limited, and it is externally connected to a controller to control all electronic components in this device;

[0025] In the specific implementation process, it is worth noting that the size of the distribution box 1 can be set according to the model of the distillation column, so that the distribution device can meet the distribution of the distillation column. The two-way auger 21 is an auger with opposite directions on both sides. When the auger rotates, it can make the liquid in the distribution box 1 flow to both sides, so that the liquid in the distribution box 1 can evenly enter the distillation block 13 through the distillation pipe 23 and enter the interior of the distillation column. Moreover, the distillation block 13 is provided with an opening corresponding to the distillation column, so that the liquid can flow into the distillation column.

[0026] Furthermore, the discharge device 24 includes a baffle 241, a gear 242, a belt 243, and a second servo motor 244. The baffle 241 is rotatably connected to the inner wall of the diverter block 13 via a sealed bearing. The gear 242 is fixedly connected to one end of the baffle 241 extending to the outer wall of the diverter block 13. The belt 243 is meshed with the outer wall of the gear 242. The second servo motor 244 is fixedly connected to the outer wall of the fixed housing 12, and one end of its output end extending into the interior of the fixed housing 12 is fixedly connected to the outer wall of the gear 242. The gear 242 and the belt 243 work together to drive the baffle 241 to rotate. The model of the second servo motor 244 is not limited, as long as it meets the actual usage requirements.

[0027] In the specific implementation process, it is worth noting that a rubber sleeve is provided at the part where the baffle 241 contacts the diversion block 13. This allows the baffle 241 to be in close contact with the inner wall of the diversion block 13, preventing the liquid from flowing out through the analysis between the diversion blocks 13. Moreover, the number of baffles 241 is the same as the number of openings on the diversion block 13, and the number of gears 242 corresponds to the number of baffles 241. A belt 243 is meshed with the outer wall of the gear 242, and the inner wall of the belt 243 is provided with teeth that mesh with the gear 242. This ensures that the belt 243 meshes with the outer wall of the gear 242, and under the drive of the second servo motor 244, these gears 242 rotate synchronously to open the baffle 241.

[0028] Furthermore, the inside of the diversion block 13 is provided with several accumulation cavities 14;

[0029] In the specific implementation process, it is worth noting that the accumulation chamber 14 is used to store the diverted liquid. When the liquid is released, the baffle 241 will open the accumulation chamber 14 and close it at the same time. In this way, when the liquid in the accumulation chamber 14 flows out, the diversion can be uniform.

[0030] Specifically, when using this high-efficiency distillation column distributor, after the liquid enters the distribution box 1, the external controller controls the first servo motor 22 to drive the bidirectional auger 21 to rotate, causing the liquid to move to both sides inside the distribution box 1 and flow into the distribution block 13 through the distribution pipe 23 connected to the bottom of the distribution box 1. This causes the liquid to accumulate in the accumulation chamber 14, and the storage volume in the accumulation chamber 14 is greater than the amount of liquid distributed each time. Therefore, the external controller controls the second servo motor 244 to rotate, and under the meshing of the gear 242 and the belt 243, it drives the baffle 241 in the distribution block 13 to rotate, opening the opening at the bottom of the distribution block 13, allowing the liquid to enter the interior of the distillation column, thus making the distributed liquid more uniform.

[0031] Example 2: From Figure 1-5 It can be seen that the top of the distribution box 1 is connected to the connecting pipe 11, and the top of the connecting pipe 11 is equipped with a filter device 3.

[0032] In the specific implementation process, it is worth noting that a filter device 3 is installed on the top of the connecting pipe 11 to remove liquid residues, so that the quality of the distilled product is more stable.

[0033] Furthermore, the filter device 3 includes a housing 31, a filter screen 32, a fixing plate 33, and a sealing gasket 34. The housing 31 is installed on the top of the connecting pipe 11; the filter screen 32 is disposed inside the housing 31; the fixing plate 33 is fixedly connected to one end of the filter screen 32 and is fixedly connected to the outer wall of the housing 31 by bolts; the sealing gasket 34 is installed between the fixing plate 33 and the housing 31; wherein, through the cooperation of the fixing plate 33 and the filter screen 32, the filter screen 32 is fixed inside the housing 31, and the sealing gasket 34 can seal the fixing plate 33 and the housing 31.

[0034] In the specific implementation process, it is worth noting that the material of the filter screen 32 is selected according to the actual situation, so it will not be elaborated here. When installing the fixing plate 33, the sealing gasket 34 is placed between the fixing plate 33 and the box 31. This can prevent the liquid from leaking when passing through the filter device 3. The sealing gasket 34 is made of rubber. Utilizing the variability of the rubber material itself, it can seal the gap between the fixing plate 33 and the box 31 when it is squeezed.

[0035] Specifically, based on the above embodiment, the accumulated liquid is input into the distribution device through the connecting pipe 11. Before entering the distribution device, the accumulated liquid first enters the housing 31. Under the action of the filter screen 32, the liquid residue in the accumulated liquid is removed to avoid affecting the quality of the product after entering the distillation tower. When replacing the filter screen 32, the fixing plate 33 is removed from the housing 31 to replace the filter screen 32. After replacement, the fixing plate 33 is inserted into the housing 31 and fixed with bolts so that the fixing plate 33 presses against the sealing gasket 34 to prevent leakage between the fixing plate 33 and the housing 31.
