The distillation tower used to produce furanone is a highly efficient, energy-saving, and environmentally friendly separation equipment, mainly used to separate miscible liquid mixtures.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The distillation tower for producing furanone is provided with a stirring mechanism, etc., so that during distillation, the steam generated by the distillation of the tower body enters the first fixed box through the steam pipe and the first connecting pipe, and enters the condenser pipe through the inlet for condensation. At the same time, the circulation pump is started, so that the cooling water can enter the shell after being cooled by the heat exchange of the heat exchanger, and can pass through the first through hole on the first partition and the second through hole on the second partition from bottom to top in sequence, which can reduce the flow rate of the cooling water and increase the path of the cooling water, thereby improving the efficiency and effect of condensation. Moreover, when the cooling water flows out of the shell through the return pipe, it can enter the second fixed box and impact the surface of the second baffle. , so that the second rotating shaft and the disc rotate, when the conical rod abuts against the top of the pushing plate, the pushing plate and the moving rod can be pushed downward, and at the same time, the slider moves downward along the guide rod, and the first spring is compressed. When the conical rod passes over the top of the pushing plate, the moving rod and the connecting rod can move upward and reset under the action of the first spring, and so on, the rack can be reciprocated up and down, thereby pushing the gear and the rotating rod to reciprocate, and then the blades can reciprocate and stir the cooling water between the partition assemblies, so that the heat absorption efficiency of the cooling water is higher and the effect is better, thereby improving the efficiency and effect of condensation, and the condensed furanone liquid is collected through the outlet.

[0017] The distillation tower for producing furanone is provided with a speed limiting mechanism, etc., so that during distillation, the steam generated by the distillation of the tower body enters the first fixed box through the steam pipe and the first connecting pipe, and enters the condenser through the inlet for condensation. When the steam enters the first fixed box, it impacts the surface of the first baffle, causing the first rotating shaft to rotate, and the rotation of the first rotating shaft drives the rotation of the rotating disk. At the same time, the rotation speed of the rotating disk can be determined by detecting the scale mark on the side wall of the rotating disk through the distance sensor, and then the flow rate of the steam can be determined. When the flow rate of the steam is too fast, the electromagnet is de-energized. At this time, the friction block can be abutted against the side wall of the rotating disk under the action of the third spring, so that the rotation speed of the rotating disk can be limited, thereby limiting the flow rate of the steam. , making the condensation more efficient and effective. At the same time, the moving block can be driven to move through the moving module, so as to adjust the distance between the moving block and the friction block, and the compression amount of the third spring can be adjusted, thereby adjusting the extrusion force between the friction block and the rotating disk, and the maximum flow rate of the steam can be adjusted, which has stronger applicability. After the reaction is completed, when the visual sensor detects that the rotation speed of the rotating disk is slow, the motor can be started, and at the same time, the electromagnet is energized. After the electromagnet is energized, the iron block is attracted, so that the friction block is separated from the rotating disk. At the same time, when the motor rotates, the first baffle is driven to rotate through the first rotating shaft, so that the vacuum operation can be performed, which accelerates the steam in the tower body to thoroughly enter the condenser assembly for condensation operation, thereby improving the efficiency and effect of condensation.

[0018] The distillation tower for producing furanone is provided with a pre-cooling mechanism, etc., so that during distillation, the cooling water after absorbing heat enters the second connecting pipe through the return pipe, and enters the heat exchanger for heat dissipation and cooling. At the same time, when the push plate moves up and down reciprocatingly, the piston is driven to move up and down reciprocatingly by the push rod. When the piston moves upward, negative pressure is generated in the fixed pipe. At the same time, the first one-way valve is opened and the second one-way valve is closed. At this time, external air enters the fixed pipe through the air inlet pipe. When the piston moves downward, the air in the fixed pipe can be squeezed. At the same time, the first one-way valve is closed and the second one-way valve is opened. At this time, the air in the fixed pipe is squeezed and enters the annular cover through the blowing pipe and is blown out through the blowing hole. At the same time, the cooling water in the water storage tank can enter the absorbent cotton through the cotton core, so that the second connecting pipe can be cooled, and then the cooling water is pre-cooled, which can improve the efficiency and effect of subsequent heat exchanger cooling.

[0019] The distillation tower for producing furanone is provided with a vibration mechanism, etc. When the rotating rod rotates, the cam is driven to rotate synchronously. When the tip of the cam abuts against the side wall of the push block, the movable plate is driven to move in a direction away from the condenser through the second connecting plate. At the same time, the second spring is compressed. When the tip of the cam passes over the push block, the movable plate can be moved and reset in a direction close to the condenser under the action of the second spring. In this way, the movable plate can be reciprocated. At the same time, the rubber rod is driven to reciprocate through the first connecting plate, so that the rubber rod reciprocates and vibrates the side wall of the condenser, thereby preventing the condensed furanone liquid from adhering to the inner wall of the condenser, so that the collection effect is better.

[0041] The reset mechanism 4 includes two symmetrically arranged T-shaped guide rods 402 fixedly connected to the side walls of each movable plate 301, and the side walls of the T-shaped guide rods 402 are sleeved with connecting blocks 401, the connecting blocks 401 are fixed to the top of the partition assembly, and the side walls of each T-shaped guide rod 402 are sleeved with second springs 403, which play a guiding and resetting role for the movement of the movable plate 301.

[0042] The pushing mechanism 5 includes a second connecting plate 501 fixedly connected to the side wall of the movable plate 301, and the side wall of the second connecting plate 501 is fixedly connected with a pushing block 502, the side wall fixed sleeve of the rotating rod 201 is provided with a cam 503, and the cam 503 slides on the side wall of the pushing block 502, when the rotating rod 201 rotates, it drives the cam 503 to rotate synchronously, when the tip of the cam 503 abuts against the side wall of the pushing block 502, the movable plate 301 is driven to move in a direction away from the condensation tube 1104 through the second connecting plate 501.

[0043] The moving mechanism 7 includes two symmetrically arranged sleeves 701 fixedly connected to the side wall of the moving block 611, and a sleeve rod 702 is inserted in the sleeve 701, the other end of the sleeve rod 702 is fixed to the side wall of the friction block 612, and the side wall of each sleeve 701 is sleeved with a third spring 703, the top of the moving block 611 is fixedly connected with an electromagnet 704, and the top of the friction block 612 is fixedly connected with an iron block 705. The moving block 611 can be driven to move through the moving module 608, so as to adjust the distance between the moving block 611 and the friction block 612, thereby adjusting the compression amount of the third spring 703, and then adjusting the extrusion force between the friction block 612 and the rotating disk 604, so as to adjust the maximum flow rate of the steam, and the applicability is stronger.

[0044] Working principle: When in use, the steam generated by the distillation of the tower body 101 enters the first fixed box 17 through the steam pipe 102 and the first connecting pipe 18, and enters the condenser pipe 1104 through the inlet 1102 for condensation. When the steam enters the first fixed box 17, it will impact the surface of the first baffle 602, causing the first rotating shaft 601 to rotate. The rotation of the first rotating shaft 601 drives the rotation of the rotating disk 604. At the same time, the distance sensor 606 detects the 605 scale mark on the side wall of the rotating disk 604, so as to determine the rotation speed of the rotating disk 604 and then determine the flow rate of the steam. When the flow rate of the steam is too fast, the electromagnet 704 is powered off. At this time, the friction block 612 can be abutted against the side wall of the rotating disk 604 under the action of the third spring 703, so as to limit the rotation speed of the rotating disk 604, thereby limiting the flow rate of the steam, so that the condensation efficiency is higher and the effect is better.

[0045] At the same time, the circulation pump 16 is started, so that the cooling water can enter the housing 1101 after being cooled by heat exchange in the heat exchanger 14, and can pass through the first through hole 1107 on the first partition 1105 and the second through hole 1108 on the second partition 1106 from bottom to top, which can reduce the flow rate of the cooling water and increase the path of the cooling water, thereby improving the efficiency and effect of condensation;

[0046] When the cooling water flows out of the shell 1101 through the return pipe 12, it can enter the second fixed box 905 and impact the surface of the second baffle 907, so that the second rotating shaft 906 and the disc 908 rotate. When the conical rod 909 abuts against the top of the push plate 910, the push plate 910 and the moving rod 803 can be pushed to move downward. At the same time, the slider 903 moves downward along the guide rod 902, and the first spring 904 is compressed. When the conical rod 909 passes over the top of the push plate 910, the moving rod 803 and the connecting rod 804 can move upward and reset under the action of the first spring 904. This reciprocating process can make the rack 802 reciprocate up and down, thereby pushing the gear 801 and the rotating rod 201 to reciprocate, and then the blade 202 can reciprocate and stir the cooling water between the partition assembly, so that the heat absorption efficiency of the cooling water is higher and the effect is better, thereby improving the efficiency and effect of condensation, and the condensed furanone liquid is collected through the outlet 1103;

[0047] At the same time, when the rotating rod 201 rotates, the cam 503 is driven to rotate synchronously. When the tip of the cam 503 abuts against the side wall of the pushing block 502, the moving plate 301 is driven to move away from the condensing tube 1104 through the second connecting plate 501. At the same time, the second spring 403 is compressed. When the tip of the cam 503 passes over the pushing block 502, the moving plate 301 can be reset in the direction close to the condensing tube 1104 under the action of the second spring 403. In this way, the moving plate 301 can be reciprocated. At the same time, the rubber rod 303 is driven to be reciprocated through the first connecting plate 302, so that the rubber rod 303 reciprocates and vibrates the side wall of the condensing tube 1104, thereby preventing the condensed furanone liquid from adhering to the inner wall of the condensing tube 1104, so that the collection effect is better.

[0048] After the reaction is completed, when the visual sensor 610 detects that the rotation speed of the rotating disk 604 is slow, the motor 603 can be started, and at the same time, the electromagnet 704 is energized. After the electromagnet 704 is energized, the iron block 705 is attracted, so that the friction block 612 is separated from the rotating disk 604. At the same time, when the motor 603 rotates, the first baffle 602 is driven to rotate through the first rotating shaft 601, so that the air extraction operation can be performed, and the steam in the tower body 101 is accelerated to completely enter the condenser assembly 11 for condensation operation, so as to improve the efficiency and effect of condensation;

[0049] Furthermore, the moving block 611 can be driven to move by the moving module 608, so as to adjust the distance between the moving block 611 and the friction block 612, and thus adjust the compression amount of the third spring 703, and further adjust the extrusion force between the friction block 612 and the rotating disk 604, so as to adjust the maximum flow rate of the steam, and the applicability is stronger;

[0050] The cooling water after absorbing heat enters the second connecting pipe 13 through the return pipe 12, and enters the heat exchanger 14 for heat dissipation and cooling. At the same time, when the push plate 910 moves up and down, the piston 1009 is driven to move up and down through the push rod 1010. When the piston 1009 moves upward, negative pressure is generated in the fixed pipe 1008. At the same time, the first one-way valve is opened and the second one-way valve is closed. At this time, the external air enters the fixed pipe 1008 through the intake pipe 1012. When the piston 1009 moves downward, it can press the fixed pipe 1008. The air inside is squeezed, and at the same time, the first one-way valve is closed and the second one-way valve is opened. At this time, the air in the fixed pipe 1008 is squeezed and enters the annular cover 1001 through the blowing pipe 1011, and is blown out through the blowing hole 1002. At the same time, the cooling water in the water storage tank 1005 can enter the absorbent cotton 1003 through the cotton core 1006, which can accelerate the evaporation of water, causing it to absorb heat and cool down, thereby cooling the second connecting pipe 13, and then pre-cooling the cooling water, which can improve the efficiency and effect of the subsequent cooling of the heat exchanger 14.
