Description

Technical Field

[0001] The invention relates to the technical field of methylal refining, in particular to a lightness removal tower used for methylal refining. Background Art

[0002] Methylal is a colorless, clear, volatile, flammable liquid with a chloroform odor and a pungent taste. It is soluble in 3 times the amount of water. It is irritating to mucous membranes and has an anesthetic effect. Inhalation of vapor can cause irritation to the nose and throat. Inhalation of high concentrations can cause dizziness, etc. It is harmful to the eyes and the damage can last for several days. Long-term skin contact can cause dry skin. It is widely used. In the process of refining methylal, the collected methylal contains a large amount of water vapor and needs to be dehydrated for a second time. In the traditional refining process, methylal is heated and cooled. It is usually refined in a light-removal tower. The light-removal tower used for methylal refining is a specially designed chemical equipment. A heating tube and a stirring device are arranged inside the tower body to heat and stir the solution to promote the evaporation and separation of methylal.

[0003] However, when the existing light-removal tower for methylal refining is used, the steam generated by evaporation cannot quickly reach a suitable pressure due to the large space above the liquid surface. Too high or too low pressure will affect the efficiency of evaporation. At the same time, it is not convenient to detect the evaporation rate. Although increasing the evaporation rate is our goal, too fast evaporation rate may cause precipitation or crystallization of certain components in the solution, affecting the quality and stability of the final product. Therefore, in actual operation, it is necessary to reasonably control the evaporation rate. Moreover, as the evaporation gradually proceeds, when the concentration of the methylal liquid is low, the evaporation rate is slow, which will affect the evaporation efficiency, and then affect the efficiency and quality of methylal refining.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The light-removal tower for methylal refining is provided with a detection mechanism, etc., when methylal is being refined, methylal is supplied into the tower body through the liquid inlet valve for heating and evaporation, and at the same time, the motor is started, the rotation of the motor drives the rotation of the gear, thereby driving the gear ring to rotate, and then driving the rotating tube and the stirring blade to rotate, so that the methylal in the tower body can be stirred, and the evaporation efficiency can be improved. The generated steam can flow upward through the second through hole and the first through hole. As the evaporation proceeds, the pressure in the tower body gradually increases. Since the space above the liquid is small, it can quickly reach a suitable pressure. When the suitable pressure is reached, After the force is generated, when the steam continues to increase, it can push the first counterweight block and the first T-shaped guide rod to move upward. At the same time, when the first T-shaped guide rod moves upward, it can drive the ring to move upward synchronously, and can drive the push pin to slide in the slide groove through the first connecting block and the first mounting block, thereby pushing the rotating plate to rotate upward along the rotating rod. When the sensing block contacts the proximity switch, the steam valve is opened, and a part of the steam in the tower body is discharged through the external exhaust equipment and cooled and collected. At this time, the first counterweight block can move downward under the action of gravity and ensure that the pressure in the tower body is in a suitable range, which can improve the efficiency of methylal refining.

[0016] (2) This light-removal tower for methylal refining is provided with a detection component, etc., when methylal is evaporated and refined, as the steam in the tower body gradually increases, the first counterweight block and the first T-shaped guide rod gradually move upward, and at the same time, can push the rotating rod to rotate. When the rotating rod rotates, it can drive the pointer to rotate, and the evaporation speed of the methylal can be determined by observing the change in the angle mark indicated by the pointer within a certain period of time through a visual sensor, so as to facilitate the detection of the evaporation speed, avoid the evaporation speed being too fast, and ensure the quality of methylal refining. As the evaporation proceeds, the methylal concentration becomes lower and lower. When it is detected that the evaporation speed is slow, This indicates that the methylal concentration is low. At this time, the first electromagnet is powered off. Under the action of the first spring, the electric heating plate is driven to move upward and fit with the bottom of the disc through the second T-shaped guide rod and the U-shaped block, and the electric heating plate can seal the first through hole. At the same time, the second electromagnet is powered on. After the second electromagnet is powered on, it attracts the second iron block, so that the pushing block moves toward the second mounting block. At the same time, the second spring is compressed, and when the rotating tube rotates, the tapered rod can be driven to rotate through the fixed ring. When the tapered rod is against the side wall of the pushing block, the pushing block can be pushed to move upward. At the same time, the moving plate is driven to move toward the second mounting block through the reset mechanism and the moving plate. The movable rod moves upward, and at the same time, the reset spring is stretched. When the conical rod passes over the pushing block, the movable rod can move downward and reset under the action of the reset spring, and so on and so forth, so that the movable rod can drive the piston to move up and down reciprocatingly. When the piston moves upward, negative pressure is generated in the rotating tube. At the same time, the first one-way valve is closed and the second one-way valve is opened. At this time, the methylal liquid in the tower body can enter the rotating tube through the liquid inlet hole and the liquid inlet pipe. When the piston moves downward, the liquid in the rotating tube can be squeezed. At the same time, the first one-way valve is opened and the second one-way valve is closed. At this time, the liquid in the rotating tube can enter the first annular cover through the liquid outlet pipe and the hose. Then, After entering the second annular cover through the third through hole, it is sprayed on the upper surface of the disc through the spray hole. At the same time, it is thrown outward and spread out under the action of centrifugal force to form a thin layer of liquid, and can enter the first through hole. The excess liquid can be thrown to the inner wall of the tower body and flow downward. At the same time, the electric heating plate is started to heat the disc, which can increase the evaporation area, thereby improving the evaporation efficiency, and then improving the efficiency of methylal refining. At the same time, when the rotating tube rotates, it can drive the piston and the liquid inlet pipe to rotate synchronously, and when the piston moves up and down reciprocatingly, it can drive the liquid inlet pipe to move. At the same time, the telescopic cover is deformed, making the liquid extraction more uniform.

[0017] (3) The light-removal tower for methylal refining is provided with a smearing mechanism, etc., so that when the methylal liquid enters the second annular cover, it can enter the fixed box through the connecting pipe, and can push the second counterweight block to move upward. Moreover, under the gravity of the second counterweight block, the methylal liquid can pass through the sponge block and be smeared on the upper surface of the disc, so that the thin layer of liquid is more comprehensive and uniform, which can improve the efficiency of evaporation, and thus improve the efficiency of methylal refining.

When the rotating tube 11 rotates, the tapered rod 704 can be driven to rotate through the fixing ring 703. When the tapered rod 704 abuts against the side wall of the push block 702, the push block 702 can be pushed to move upward. At the same time, the moving rod 502 is driven to move upward through the return mechanism and the moving plate 701. At the same time, the return spring 510 is stretched. When the tapered rod 704 passes over the push block 702, the moving rod 502 can move downward and reset under the action of the return spring 510. This reciprocating process can enable the moving rod 502 to drive the piston 503 to move back and forth up and down.

[0028] The reset mechanism includes a support plate 801 fixedly connected to the bottom of the movable plate 701, and two symmetrically arranged third T-shaped guide rods 901 are inserted into the side wall of the support plate 801, one end of the third T-shaped guide rod 901 is fixed to the side wall of the push block 702, and the side wall of each third T-shaped guide rod 901 is sleeved with a second spring 902, which guides and resets the movement of the push block 702.

[0029] The pushing assembly includes a second mounting block 802 fixedly connected to the bottom of the support plate 801, a second electromagnet 803 is fixedly connected to the side wall of the second mounting block 802, and a second iron block 804 is fixedly connected to the side wall of the pushing block 702. When the second electromagnet 803 is energized, the second electromagnet 803 attracts the second iron block 804, so that the pushing block 702 moves toward the direction close to the second mounting block 802, and at the same time, the second spring 902 is compressed.

[0030] The driving mechanism includes a gear ring 1001 fixedly mounted on the side wall of the rotating tube 11, and an L-shaped plate 1003 is fixedly connected to the top of the tower body 101, and a motor 1004 is fixedly connected to the top of the L-shaped plate 1003, and a gear 1002 is fixedly connected to the output end of the motor 1004, and the gear 1002 is meshed with the gear ring 1001. When the motor 1004 is started, the rotation of the motor 1004 drives the rotation of the gear 1002, thereby driving the gear ring 1001 to rotate, and further driving the rotating tube 11 and the stirring blade 12 to rotate, so as to stir the methylal in the tower body 101 and improve the evaporation efficiency.

[0031] Working principle: When in use, when methylal is refined, methylal is supplied into the tower body 101 through the liquid inlet valve 103 for heating and evaporation. At the same time, the motor 1004 is started. The rotation of the motor 1004 drives the rotation of the gear 1002, thereby driving the ring gear 1001 to rotate, and then driving the rotating tube 11 and the stirring blade 12 to rotate, which can stir the methylal in the tower body 101 and improve the evaporation efficiency. The generated steam can flow upward through the second through hole 16 and the first through hole 14. As the evaporation proceeds, the pressure in the tower body 101 gradually increases. Since the space above the liquid is small, the appropriate pressure can be quickly reached.

[0032] After reaching a suitable pressure, when the steam continues to increase, it can push the first counterweight block 19 and the first T-shaped guide rod 21 to move upward. At the same time, when the first T-shaped guide rod 21 moves upward, it can drive the ring 303 to move upward synchronously, and can drive the push pin 310 to slide in the slide groove 309 through the first connecting block 304 and the first mounting block 308, thereby pushing the rotating plate 307 to rotate upward along the rotating rod 306. When the sensing block 311 contacts the proximity switch 302, the steam valve 104 is opened, and a part of the steam in the tower body 101 is discharged through an external exhaust device and cooled and collected. At this time, the first counterweight block 19 can move downward under the action of gravity and ensure that the pressure in the tower body 101 is within a suitable range, which can improve the efficiency of methylal refining.

[0033] When methylal is evaporated and refined, as the steam in the tower body 101 gradually increases, the first counterweight 19 and the first T-shaped guide rod 21 gradually move upward, and at the same time, can push the rotating rod 306 to rotate. When the rotating rod 306 rotates, it can drive the pointer 401 to rotate, and the change of the angle mark 402 indicated by the pointer 401 within a certain period of time can be observed by the visual sensor 404, so that the evaporation speed of the methylal can be determined, which is convenient for detecting the evaporation speed, avoiding the evaporation speed being too fast, and ensuring the quality of the methylal refining. As the evaporation proceeds, the methylal concentration increases. When the evaporation speed is detected to be slow, it means that the methylal concentration is low. At this time, the first electromagnet 605 is powered off. Under the action of the first spring 606, the electric heating plate 15 is driven to move upward through the second T-shaped guide rod 601 and the U-shaped block 607 and fits with the bottom of the disc 13. In addition, the electric heating plate 15 can seal the first through hole 14. At the same time, the second electromagnet 803 is powered on. After the second electromagnet 803 is powered on, it attracts the second iron block 804, so that the push block 702 moves toward the second mounting block 802. At the same time, the second spring 902 is compressed.

[0034] When the rotating tube 11 rotates, the conical rod 704 can be driven to rotate through the fixing ring 703. When the conical rod 704 abuts against the side wall of the pushing block 702, the pushing block 702 can be pushed to move upward. At the same time, the moving rod 502 is driven to move upward through the reset mechanism and the moving plate 701. At the same time, the reset spring 510 is stretched. When the conical rod 704 passes over the pushing block 702, the moving rod 502 can move downward and reset under the action of the reset spring 510. This reciprocating process can enable the moving rod 502 to drive the piston 503 to move up and down.

[0035] When the piston 503 moves upward, negative pressure is generated in the rotating tube 11. At the same time, the first one-way valve is closed and the second one-way valve is opened. At this time, the methylal liquid in the tower body 101 can enter the rotating tube 11 through the liquid inlet hole 508 and the liquid inlet pipe 507. When the piston 503 moves downward, the liquid in the rotating tube 11 can be squeezed. At the same time, the first one-way valve is opened and the second one-way valve is closed. At this time, the liquid in the rotating tube 11 can enter the first annular cover 22 through the liquid outlet pipe 504 and the hose 505, and then enter the second annular cover 24 through the third through hole 23, and then sprayed on the upper surface of the disc 13 through the liquid spray hole 25. , under the action of centrifugal force, it is thrown outward and spread out to form a thin layer of liquid, and can enter the first through hole 14, and the excess liquid can be thrown to the inner wall of the tower body 101 and flow downward. At the same time, starting the electric heating plate 15 to heat the disc 13 can increase the evaporation area, thereby improving the evaporation efficiency, and then improving the efficiency of methylal refining. At the same time, when the rotating tube 11 rotates, it can drive the piston 503 and the liquid inlet pipe 507 to rotate synchronously, and when the piston 503 moves up and down, it can drive the liquid inlet pipe 507 to move. At the same time, the telescopic cover 509 is deformed, making the liquid extraction more uniform.

[0036] Furthermore, when the methylal liquid enters the second annular cover 24, it can enter the fixed box 201 through the connecting pipe 204, and can push the second counterweight block 203 to move upward. Moreover, under the gravity of the second counterweight block 203, the methylal liquid can pass through the sponge block 202 and then be smeared on the upper surface of the disc 13, so that the thin layer of liquid is more comprehensive and uniform, which can improve the efficiency of evaporation, and thus improve the efficiency of methylal refining. After complete evaporation is completed, the first electromagnet 605 is energized, and the first electromagnet 605 attracts the first iron block 603, so that the electric heating plate 15 moves downward, and the first spring 606 is compressed. Finally, the steam valve 104 is opened, and all the steam in the tower body 101 is discharged and cooled and collected through external exhaust equipment.
