Abstract
Description
Technical Field
[0001] This invention relates to the field of dehydration apparatus, and particularly to a dehydration apparatus for methylene disulfonate and its method of use. Background Technology
[0002] With the development of industrial technology, modern dehydration equipment technology has become more and more sophisticated. Methyl disulfonate is used as an additive in batteries. This additive can increase the stability and lifespan of batteries. Esters are formed by the removal of a water molecule from acids and alcohols. After the formation of esters, water is produced, which requires ester dehydration equipment. Traditional ester dehydration devices evaporate water by heating. However, esters are quite viscous, and during the heating process, water bubbles formed inside the esters escape to the outside, which affects the rate of water removal. Secondly, under standard atmospheric pressure, the vaporization and heat of water are relatively high, which not only requires more heat input but also results in a relatively low vaporization rate. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a dehydration device for methylene disulfonate and its usage method. In operation, the produced methylene disulfonate material is fed into a sealed chamber from the top. A heating element is then energized to heat the methylene disulfonate material inside the chamber. During heating, a stepper motor drives a reduction gearbox to rotate via a first drive disc and a reduction belt. A crank handle on the side wall of the reduction gearbox rotates accordingly. Each rotation of the crank handle causes a rack to reciprocate, and the rack's reciprocating motion causes the gear disk to rotate at a certain angle. The horizontal shaft at the center of the gear disk rotates synchronously. The impeller and four inclined blades at the end of the horizontal shaft stir the ester material longitudinally. The simultaneous heating and stirring of the ester material increases the rate of moisture evaporation, thereby solving the problems mentioned in the background art.
[0004] To solve the above problems, the present invention provides the following technical solution: a dehydration device for methylene disulfonate, comprising a sealed chamber, a heating assembly at the bottom of the sealed chamber, a sealed cover plate at the top of the sealed chamber, an air blower at the top of the sealed cover plate, a central bearing and a tubular shaft on the inner wall of the sealed chamber, the outer ring of the central bearing being fixedly connected to the inner wall of the sealed chamber, a reduction gear turntable on one side of the central bearing, and a round rod inserted into the inner ring of the central bearing on the side wall of the reduction gear turntable. A horizontal shaft is rotatably mounted on the inner side of the tube shaft, and a stirring wheel assembly is mounted at the end of the horizontal shaft. A gear disk is fixedly mounted on the horizontal shaft. A rocker bearing is also mounted on the outer side of the tube shaft. A cantilever arm is welded to the outer ring of the rocker bearing. A slider is mounted at the end of the cantilever arm. A rack is inserted through the inner side of the slider. A crank handle is mounted on the side of the deceleration turntable opposite to the central bearing. A torque hole is mounted at the end of the rack. The end of the crank handle is inserted into the torque hole. A material mixing plate is mounted at the bottom of the sealed box. The material mixing plate and the deceleration turntable are connected to the linkage assembly.
[0005] Furthermore, the stirring wheel assembly includes an impeller fixed to the end of the horizontal shaft. The outer wall of the impeller is provided with four circular openings, each of which is provided with a positioning post. The outer wall of the positioning post is provided with an inclined blade. The axis of the inclined blade and the impeller are offset from each other by 45 degrees. The side walls of the positioning post and the circular openings are provided with a ring array of positioning threaded holes. The two sets of positioning threaded holes are fixedly connected by screws.
[0006] Furthermore, grooves are provided on both the front and rear sides of the rack, and a retaining strip is provided on the side wall of the slider, which is inserted into the grooves.
[0007] Furthermore, the top of the material plate is provided with several diverging strips, the cross-section of which is semi-circular, and the diameter of the inward-facing end of the diverging strip is smaller than that of the outward-facing end.
[0008] Furthermore, the linkage component includes a stepper motor on the inner wall of the sealed box. The output end of the stepper motor is equipped with a first drive disk and a second drive disk. The first drive disk and the reduction turntable are connected by a reduction belt. The diameter ratio between the first drive disk and the reduction turntable is 1:2. A vertical rod is set at the center of the material plate. A driven roller is set at the end of the vertical rod. The second drive disk and the driven roller are connected by a torsion belt.
[0009] Furthermore, the sealed cover plate includes a sealed cover plate, a square ring bar is provided at the top of the sealed box, the square ring bar is made of soft rubber, the cross-section of the square ring bar is semi-circular, and an annular groove matching the square ring bar is provided on the bottom edge of the sealed cover plate.
[0010] Furthermore, the input end of the air compressor is provided with a bent steel pipe, which passes through the sealed cover plate and extends into the interior of the sealed box. The sealed cover plate is provided with a plunger hole that matches the bent steel pipe. A rubber plunger ring is fitted on the outside of the bent steel pipe. The output pipe of the air compressor is connected to the molecular sieve tower, and the molecular sieve tower is connected to the interior of the sealed box again through the return pipe.
[0011] Furthermore, the heating assembly includes a base plate, a heating frame is provided at the top of the base plate, an electric heating wire is provided inside the heating frame, and a temperature detector is provided on the inner side wall of the sealed box.
[0012] Furthermore, the bottom plate of the sealed box is made of copper, and the bottom plate of the sealed box and the bottom opening of the sealed box are detachable.
[0013] Furthermore, the following steps are included: S1. The produced methyl disulfonate material is fed into the sealed box from the top. After being mixed with a low-boiling-point solvent, the methyl disulfonate material becomes thinner, making it easy to stir. At this time, the heating wire is energized to heat the methyl disulfonate material inside the sealed box. During the heating process, the stepper motor drives the reduction turntable to rotate through the first drive plate and the reduction belt. The crank handle on the side wall of the reduction turntable rotates along with it. Each rotation of the crank handle drives the rack to move back and forth. During the back and forth movement of the rack, the gear plate rotates back and forth at a certain angle. The horizontal shaft at the center of the gear plate rotates synchronously. The impeller and four inclined blades at the end of the horizontal shaft stir the ester material longitudinally. The simultaneous heating and stirring of the ester material increases the rate of water evaporation. The water can fully contact the heated base part to quickly vaporize. S2. While the first drive disc is rotating, the second drive disc on the side wall of the first drive disc will also rotate together. The second drive disc drives the driven roller to rotate through the torsion belt. The upright at the bottom of the driven roller and the material plate rotate synchronously. The material plate will stir and mix the material laterally during the process. S3. After the sealing cover is engaged at the top of the sealed chamber, the chamber and the cavity inside the sealing cover form a sealed chamber. The air pump starts to draw air from the sealed chamber, creating a negative pressure in the cavity inside the sealed chamber. As the air pressure decreases, the boiling point of water decreases, which increases the rate of water vaporization. Water vapor and a small amount of ester molecules are pushed into the molecular sieve tower by the air pump. The molecular sieve tower separates water molecules and ester molecules. The condensed water droplets and low-boiling-point solvents are discharged. The condensed esters are pushed back into the sealed chamber through the reflux pipe. The esters are repeatedly evaporated until the moisture content is reduced to the processing standard.
[0014] The beneficial effects of this invention are: Firstly, when using the device, the produced methyl disulfonate material is fed into the sealed box from the top. After being mixed with a low-boiling-point solvent, the methyl disulfonate material becomes thinner, making it easy to stir. At this time, the heating wire is energized to heat the methyl disulfonate material inside the sealed box. During the heating process, the stepper motor drives the reduction turntable to rotate through the first drive plate and the reduction belt. The crank handle on the side wall of the reduction turntable rotates accordingly. Each rotation of the crank handle drives the rack to move back and forth. During the back and forth movement of the rack, the gear plate rotates back and forth at a certain angle. The horizontal shaft at the center of the gear plate rotates synchronously. The impeller and four inclined blades at the end of the horizontal shaft stir the ester material longitudinally. The simultaneous heating and stirring of the ester material increases the rate of water evaporation.
[0015] Secondly, while the first drive disc is rotating, the second drive disc on the side wall of the first drive disc will also rotate together. The second drive disc drives the driven roller to rotate through the torsion belt. The upright at the bottom of the driven roller and the material mixing plate rotate synchronously. The material mixing plate mixes the material laterally in the process, realizing the linkage effect.
[0016] Third, after the sealing cover is engaged at the top of the sealed box, the sealed box and the chamber inside the sealing cover form a sealed chamber. The air pump starts to draw air from inside the sealed box, creating a negative pressure state inside the chamber. When the air pressure decreases, the boiling point of water decreases, which increases the rate of water vaporization. Water vapor and a small amount of ester molecules are pushed into the molecular sieve tower by the air pump. The molecular sieve tower separates water molecules and ester molecules. The condensed water droplets and low-boiling-point solvents are discharged, and the condensed esters are pushed back into the sealed box through the reflux pipe. Attached Figure Description

The material mixing plate 4 and the deceleration turntable 6 are connected to the linkage assembly. The produced methyl disulfonate material is put into the sealed box 1 from the top. During the heating of the sealed box 1, the crank 603 rotates once, which drives the rack 11 to move back and forth. During the back and forth movement of the rack 11, the gear disk 9 is rotated back and forth at a certain angle. The horizontal shaft 12 at the center of the gear disk 9 will rotate synchronously. The stirring wheel assembly at the end of the horizontal shaft 12 stirs the ester material in the longitudinal direction. The ester material is heated and stirred at the same time, which increases the rate of water evaporation.
[0028] The stirring wheel assembly includes an impeller 8 fixed to the end of the horizontal shaft 12. The outer wall of the impeller 8 has four circular openings, each containing a positioning post 801. The outer wall of the positioning post 801 has an inclined blade 802. The axis of the inclined blade 802 and the impeller 8 are offset from each other by 45 degrees. The side walls of the positioning post 801 and the circular openings have an annular array of positioning threaded holes. The two sets of positioning threaded holes are fixedly connected by screws. The screws can be pulled out of the positioning threaded holes. After the positioning post 801 and the circular openings are repositioned at the same angle, they are fixed again. Then, the operator can adjust the equipment according to the processing situation.
[0029] The rack 11 has grooves on both the front and rear sides, and the slider 1003 has a retaining strip inserted in the groove on its side wall. The rack 11 can be inserted into the slider 1003, and the cooperation between the groove and the retaining strip can prevent the rack 11 from falling off.
[0030] The top of the material plate 4 is provided with several diverging strips. The cross-section of the diverging strips is semi-circular. The diameter of the inner end of the diverging strip is smaller than that of the outer end. The semi-circular diverging strips facilitate the removal of debris by cleaning tools such as brushes. The semi-circular structure will not form gaps for dirt to accumulate on the top surface of the material plate 4.

A first drive disk 501 and a second drive disk 502 are installed at the output end of the stepper motor 5.

A vertical rod 401 is set at the center of the material plate 4. A driven roller 7 is set at the end of the vertical rod 401. The second drive disk 502 and the driven roller 7 are connected by a torsion belt 701. The stepper motor 5 drives the reduction turntable 6 to rotate through the first drive disk 501 and the reduction belt 601. The crank 603 on the side wall of the reduction turntable 6 rotates together. While the first drive disk 501 rotates, the second drive disk 502 on the side wall of the first drive disk 501 also rotates together. The second drive disk 502 drives the driven roller 7 to rotate through the torsion belt 701. The vertical rod 401 at the bottom of the driven roller 7 and the material plate 4 rotate synchronously, realizing the linkage effect.
[0032] The sealed cover plate includes a sealed cover plate 2. A square ring bar 101 is provided at the top of the sealed box 1. The square ring bar 101 is made of soft rubber and has a semi-circular cross-section. An annular groove matching the square ring bar 101 is provided on the bottom edge of the sealed cover plate 2. The structure of the square ring bar 101 between the sealed box 1 and the sealed cover plate 2 isolates the airflow, thereby forming a sealed chamber between the sealed box 1 and the sealed cover plate 2.
[0033] The input end of the air compressor 201 is equipped with a bent steel pipe, which passes through the sealed cover plate 2 and extends into the sealed box 1. The sealed cover plate 2 is provided with a plunger hole that matches the bent steel pipe. A rubber plunger ring is fitted on the outside of the bent steel pipe. The output pipe of the air compressor 201 is connected to the molecular sieve tower. The molecular sieve tower is connected to the interior of the sealed box 1 again through the return pipe. The air compressor 201 begins to draw air from the interior of the sealed box 1, creating a negative pressure state in the chamber inside the sealed box 1. When the air pressure decreases, the boiling point of water decreases, thereby increasing the rate of water vaporization. Water vapor and a small amount of ester molecules are pushed into the molecular sieve tower by the air compressor. The molecular sieve tower separates water molecules and ester molecules, and the condensed water droplets are discharged. The condensed esters are pushed back into the sealed box 1 again through the return pipe. The molecular sieve tower and the entire condensation equipment in this case are existing technologies, and their specific structures are not described in detail.
[0034] The heating assembly includes a base plate 3, a heating frame 301 is provided at the top of the base plate 3, an electric heating wire 302 is provided inside the heating frame 301, and a temperature detector is provided on the inner wall of the sealed box 1. The heating temperature is adjusted according to the viscosity of the ester. The heating frame 301 can be installed or removed to adjust the heating rate.
[0035] The bottom plate of the sealed box 1 is made of copper, and the bottom plate of the sealed box 1 and the bottom opening of the sealed box 1 are detachable. The copper bottom plate of the sealed box 1 increases the heat conduction rate, and the bottom plate can be disassembled periodically for cleaning.
[0036] Includes the following steps: S1. The produced methyl disulfonate material is fed into the sealed box 1 from the top. After being mixed with a low-boiling-point solvent, the methyl disulfonate material becomes thinner, making it easy to stir. At this time, the heating wire 302 is energized to heat the methyl disulfonate material inside the sealed box 1. During the heating process, the stepper motor 5 drives the reduction turntable 6 to rotate through the first drive disk 501 and the reduction belt 601. The crank handle 603 on the side wall of the reduction turntable 6 rotates together. Each rotation of the crank handle 603 drives the rack 11 to move back and forth. During the back and forth movement of the rack 11, the gear disk 9 is rotated back and forth at a certain angle. The horizontal shaft 12 at the center of the gear disk 9 will rotate synchronously. The impeller 8 and the four inclined blades 802 at the end of the horizontal shaft 12 will stir the ester material in the longitudinal direction. The ester material is heated and stirred at the same time, which increases the rate of water evaporation. The water can fully contact the heated base part to quickly vaporize. S2. While the first drive disk 501 is rotating, the second drive disk 502 on the side wall of the first drive disk 501 will also rotate together. The second drive disk 502 drives the driven roller 7 to rotate through the torsion belt 701. The upright 401 at the bottom of the driven roller 7 and the material plate 4 rotate synchronously. The material plate 4 stirs and mixes the material horizontally in the process. S3. After the sealing cover 2 is engaged with the top of the sealing box 1, the sealing box 1 and the internal chamber of the sealing cover 2 form a sealed chamber. The air pump 201 starts to draw air from the inside of the sealing box 1, and the internal chamber of the sealing box 1 is in a negative pressure state. When the air pressure decreases, the boiling point of water decreases, which increases the rate of water vaporization. Water vapor and a small amount of ester molecules are pushed into the molecular sieve tower by the air pump. The molecular sieve tower separates water molecules and ester molecules. The condensed water droplets and low-boiling-point solvents are discharged. The condensed esters are pushed back into the sealing box 1 through the reflux pipe. The esters are repeatedly evaporated until the moisture content is reduced to the processing standard.
[0037] Working principle: The produced methyl disulfonate material is fed into the sealed box 1 from the top. During the heating process of the sealed box 1, each rotation of the crank 603 drives the rack 11 to move back and forth. As the rack 11 moves back and forth, it drives the gear disk 9 to rotate at a certain angle. The horizontal shaft 12 at the center of the gear disk 9 rotates synchronously. The stirring wheel assembly at the end of the horizontal shaft 12 stirs the ester material longitudinally. The simultaneous heating and stirring of the ester material increases the rate of moisture evaporation. The screw can be pulled out from the positioning threaded hole. The positioning post 801 and... After the circular opening is repositioned at the correct angle, it is fixed. Then, the operator can adjust the equipment according to the processing situation. The rack 11 can be inserted into the slider 1003. The cooperation of the groove and the retaining strip prevents the rack 11 from falling off. The semi-circular three-strip design facilitates the removal of debris by cleaning tools such as brushes. The semi-circular structure prevents the formation of gaps where dirt can accumulate on the top surface of the material plate 4. The stepper motor 5 drives the reduction turntable 6 to rotate via the first drive disc 501 and the reduction belt 601. The crank handle 603 on the side wall of the reduction turntable 6 rotates accordingly. The first drive disc 501 rotates... As the first drive disc 501 rotates, the second drive disc 502 on its side wall also rotates. The second drive disc 502 drives the driven roller 7 to rotate via the torsion belt 701. The upright 401 at the bottom of the driven roller 7 and the material plate 4 rotate synchronously, achieving a linkage effect. The square ring bar 101 structure between the sealed box 1 and the sealed cover plate 2 isolates the airflow, thus forming a sealed chamber inside the sealed box 1 and the sealed cover plate 2. The air pump 201 begins to draw air from inside the sealed box 1, creating a negative pressure state inside the chamber of the sealed box 1. When the air pressure decreases, the boiling point of water decreases, which in turn increases the rate of water vaporization. Water vapor and a small amount of ester molecules are pushed into the molecular sieve tower by the air pump. The molecular sieve tower separates water molecules and ester molecules. The condensed water droplets are discharged, and the condensed esters are pushed back into the sealed box 1 through the reflux pipe. The heating temperature is adjusted according to the viscosity of the esters. The heating frame 301 can be installed or removed to adjust the heating rate by adding or removing the number of heating wires 302. The copper base plate of the sealed box 1 increases the heat conduction rate, and the base plate can be disassembled periodically for cleaning.

The methyl methylene disulfonate material produced is put into the top of the sealing box (1), the methyl methylene disulfonate material mixed with a low-boiling-point solvent becomes dilute, and then the methyl methylene disulfonate material is in a state easy to stir, at this time, the electric heating wire (302) starts to be electrified to heat the methyl methylene disulfonate material in the sealing box (1), in the heating process, the step motor (5) drives the speed reducer turntable (6) to rotate through the first driving disc (501) and the speed reducer belt (601), the rocking handle (603) on the side wall of the speed reducer turntable (6) is twisted, the rocking handle (603) drives the rack (11) to reciprocate for each rotation, the rack (11) drives the gear disc (9) to reciprocate and twist by a certain angle in the reciprocating process, the horizontal shaft (12) in the center of the gear disc (9) is twisted synchronously, and the impeller (8) and the four inclined leaves (802) at the end of the horizontal shaft (12) stir the ester material in the longitudinal direction, the heating and stirring of the ester material increase the evaporation rate of water, and the water can fully contact the heated base to quickly gasify; S2. While the first driving disc (501) rotates, the second driving disc (502) on the side wall of the first driving disc (501) also rotates synchronously, the second driving disc (502) drives the driven roller (7) to rotate through the twisting belt (701), the vertical rod (401) at the bottom end of the driven roller (7) and the material plate (4) rotate synchronously, and the material plate (4) stirs the material horizontally in the process. S3. After the sealing cover (2) is engaged on the top end of the sealing box (1), the chamber inside the sealing box (1) and the sealing cover (2) forms a sealed chamber, the air machine (201) starts to extract the air inside the sealing box (1), the chamber inside the sealing box (1) forms a state of negative pressure, the boiling point of water decreases when the air pressure decreases, thereby increasing the rate of water vaporization, water vapor and a small amount of ester molecules are pushed into the molecular sieve tower by the air machine, the water molecules and ester molecules are separated in the molecular sieve tower, the condensed water droplets and low-boiling-point solvents are discharged, and the condensed ester is pushed back into the sealing box (1) through the reflux pipe again, and the ester is repeatedly evaporated until the water content is reduced to the processing standard.
