Description

Technical Field

[0001] This invention relates to the field of chemical processing technology, specifically to an apparatus and process for the continuous crystallization of aminosulfonic acid. Background Art

[0002] Aminosulfonic acid, also known as ammonium sulfate, is an important organic compound with the chemical formula NH2SO3H. It has a wide range of applications in industry and laboratories, especially in cleaning agents, electroplating, metal processing, water treatment, and pharmaceuticals.

[0003] Existing continuous crystallization production equipment for aminosulfonic acid involves adding urea (CO(NH2)2), fuming sulfuric acid (SO3·nH2O), and a certain amount of additives in a specific ratio into the feed pipe. The raw materials enter the heating cylinder, and the heating and reaction stirring modules are activated to accelerate the reaction and form a solution. The resulting solution is then added to a cooling tank, where a cooling and stirring module is activated to assist the crystallization reaction. The resulting aminosulfonic acid crystals and mother liquor enter a filtration module, where the crystals are filtered out from the mother liquor, thus achieving continuous crystallization of aminosulfonic acid. However, in actual use, after the aminosulfonic acid crystals are filtered out, due to the properties of the crystals and the mother liquor, a certain amount of mother liquor remains on the surface of the separated crystals. This requires subsequent washing with pure water or other solvents to remove impurities, a process that takes a considerable amount of time. This increases the time required for continuous crystallization of aminosulfonic acid and reduces its efficiency. Summary of the Invention

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing an apparatus and process for continuous crystallization of aminosulfonic acid. During the continuous crystallization process of aminosulfonic acid, when filtering aminosulfonic acid crystals from the mother liquor through a filter cylinder, pure water is sprayed into the interior of the filter cylinder through a nozzle. The continuous reciprocating shaking of the filter cylinder during rotation allows the aminosulfonic acid crystals to be washed quickly and evenly to remove impurities, effectively increasing the efficiency of continuous crystallization of aminosulfonic acid.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a device and process for continuous crystallization production of aminosulfonic acid, including a filter box and a production box. The production box is fixed to the upper surface of the filter box by bolts. A feed pipe is provided at the top of the production box. A partition plate is provided in the middle of the inside of the production box. A conveying pipe is provided in the middle of the partition plate. A discharge pipe is provided between the production box and the filter box. A solenoid valve one is provided inside the feed pipe. A solenoid valve two is provided inside the conveying pipe. A solenoid valve three is provided inside the discharge pipe. A production reaction module is provided inside the production box. A filtration and cleaning module is provided inside the filter box. The lower surface of the filter box is provided with evenly distributed support legs. A buffer rubber pad is glued and fixed to the lower surface of each support leg.

[0006] As a further improvement of the present invention, the production reaction module includes a reaction tank rotatably disposed between the feed pipe and the conveying pipe, a cooling tank rotatably disposed between the conveying pipe and the discharge pipe, a heating module disposed inside the reaction tank, a cooling module disposed inside the cooling tank, a stirring unit disposed inside both the reaction tank and the cooling tank, and a rotation drive unit disposed between the reaction tank, the cooling tank and the partition plate for driving the reaction tank and the cooling tank to reciprocate; the stirring unit includes a stirring paddle rotatably disposed in the middle of the inside of the reaction tank and the cooling tank, and a drive motor is disposed on the outside of both the reaction tank and the cooling tank, the output shaft of the drive motor being fixed to the adjacent stirring paddles by couplings; the rotation drive unit includes a driven gear fixedly sleeved on the lower end of the reaction tank and the upper end of the cooling tank, L-shaped seats are disposed on the upper and lower sides of the partition plate, and a driving gear is rotatably disposed on the L-shaped seats by a rotating shaft, the driving gear being meshed with the adjacent driven gear; a dual-shaft motor is disposed in the mounting groove opened on the partition plate, and the output shaft of the dual-shaft motor is fixed to the adjacent rotating shaft by a coupling.

[0007] As a further improvement of the present invention, the filtration and cleaning module includes a clearance groove on the outside of the filter box, a guide rail inside the filter box, a sliding seat slidably disposed on the outside of the guide rail, a rotating seat at the bottom of the sliding seat, a filter cylinder rotatably disposed inside the rotating seat, a connection port on the rotating seat being connected to the feed pipe via a telescopic hose, a uniformly distributed perforation hole on the outer arc surface of the filter cylinder, the filter cylinder being fitted with the clearance groove, a uniformly distributed nozzle on the top of the filter box via a mounting bracket, a water storage tank on the upper surface of the filter box, the nozzles being connected to the water storage tank via connecting water pipes, a through hole on the upper surface of the filter box cooperating with the connecting water pipes, an electrically controlled swaying unit for driving the filter cylinder to sway back and forth, and a driven rotation unit for driving the filter cylinder to rotate.

[0008] As a further improvement of the present invention, the driven rotation unit includes a driven gear two fixedly sleeved on the outer arc surface of the filter cylinder, and a rack plate is provided at the top of the filter box through a support, the rack plate being meshed with the driven gear two; the electrically controlled shaking unit includes an adjusting screw rotatably disposed on the upper side inside the filter box, a drive seat is threadedly connected to the outer side of the adjusting screw, the drive seat being rotatably connected to the outer arc surface of the filter cylinder, and a drive motor two is provided on the rear side of the filter box, the output shaft of the drive motor two being fixed to the adjusting screw through a coupling.

[0009] As a further improvement of the present invention, a control board is provided on the front side of the filter box, and solenoid valve one, solenoid valve two, solenoid valve three, heating module, cooling module, drive motor one, dual-axis motor, nozzle and drive motor two are all electrically connected to the control board.

[0010] S1. During the production of aminosulfonic acid crystals, the solenoid valve is operated by the control board to open the feed pipe. Then, a certain amount of urea, fuming sulfuric acid and a certain amount of additives are added into the feed pipe in proportion. The raw materials entering the feed pipe fall into the interior of the reaction tank under the action of gravity.

[0011] S2. The control panel regulates the operation of the heating module, cooling module, drive motor 1, and dual-shaft motor. The heating module controls the internal heating of the reaction tank, and the cooling module controls the internal cooling of the cooling tank. The output shaft of drive motor 1 drives the stirring paddle connected to it to rotate. The output shaft of the dual-shaft motor drives the rotating shaft connected to it to rotate in both forward and reverse cycles. The angle of the rotating shaft is less than 150 degrees. This causes the drive gear to drive the driven gear 1 meshing with it to rotate, so that the reaction tank and the cooling tank rotate in both forward and reverse cycles.

[0012] S3. When a certain amount of urea, fuming sulfuric acid, and a certain amount of additives are heated by the heating module in the reaction tank, the reciprocating rotation of the reaction tank and the rotation of the stirring paddle inside the reaction tank accelerate the formation of the solution. The operation of the solenoid valve 2 is controlled by the control board, so that the reaction solution enters the interior of the cooling tank through the delivery pipe and is cooled by the cooling module inside the cooling tank. The reciprocating rotation of the cooling tank and the rotation of the stirring paddle inside the cooling tank cause aminosulfonic acid crystals to be generated inside the cooling tank.

[0013] S4. The control panel regulates the operation of the nozzle and the second drive motor, causing the output shaft of the second drive motor to drive the adjusting screw connected to it to rotate in both forward and reverse cycles. Then, by adjusting the thread relationship between the adjusting screw and the drive seat, the drive seat drives the filter cylinder to continuously oscillate back and forth under the guidance of the sliding seat and the guide rail. During the back and forth oscillation of the filter cylinder, the meshing relationship between the rack plate and the driven gear second causes the driven gear second to rotate, which in turn drives the filter cylinder to rotate between the rotating seat and the drive seat. As the filter cylinder oscillates back and forth, it continuously rotates itself. The nozzle draws water from the storage tank through the connected water pipe and sprays it onto the filter cylinder.

[0014] S5. The solenoid valve is operated by the control panel, allowing the aminosulfonic acid crystals and mother liquor to enter the filter cylinder through the telescopic hose. Inside the filter cylinder, the mother liquor and aminosulfonic acid crystals move within the rotating filter cylinder as it reciprocates. This causes the mother liquor to leak through the holes on the filter cylinder, while the aminosulfonic acid crystals roll downwards within the tilted filter cylinder. During the movement of the aminosulfonic acid crystals, the water jets sprayed from the nozzles and the rotating filter cylinder work together to filter and wash the crystals. After washing, the aminosulfonic acid crystals roll out from the lower right end of the filter cylinder, achieving continuous production of aminosulfonic acid crystals.

[0015] In summary, this application has at least one of the following beneficial technical effects compared with the prior art:

[0016] Firstly, the output shafts of the dual-shaft motors drive the rotating shafts connected to them to rotate in both forward and reverse cycles, with the angle of the rotating shafts being less than 150 degrees. This causes the driving gears to drive the driven gears meshing with them to rotate, resulting in the reaction tank and cooling tank rotating back and forth.

[0017] Secondly, the output shaft of the drive motor drives the stirring paddle connected to it to rotate. The reciprocating rotation of the cooling tank and the rotation of the stirring paddle inside the cooling tank cause aminosulfonic acid crystals to be generated inside the cooling tank. Through the reciprocating rotation of the reaction tank and the cooling tank and the rotating stirring paddle inside the reaction tank and the cooling tank, aminosulfonic acid solution and aminosulfonic acid crystals can be produced quickly, stably and continuously.

[0018] Thirdly, by adjusting the thread relationship between the lead screw and the drive seat, the drive seat drives the filter cylinder to continuously oscillate back and forth under the guidance of the sliding seat and the guide rail. The nozzle draws water from the water storage tank through the connected water pipe and sprays it onto the filter cylinder to filter and clean the crystals inside the filter cylinder.

[0019] Fourth, during the back-and-forth swaying of the filter cylinder, the meshing relationship between the rack plate and the driven gear two drives the driven gear two to rotate, causing the filter cylinder to rotate between the rotating seat and the drive seat. As the filter cylinder sways back and forth, it continuously rotates itself. When the aminosulfonic acid crystals are filtered out of the mother liquor through the filter cylinder, pure water is sprayed into the inside of the filter cylinder through the nozzle. The continuous back-and-forth swaying of the filter cylinder during rotation allows the aminosulfonic acid crystals to be washed quickly and evenly to remove impurities, which can effectively increase the efficiency of continuous crystallization production of aminosulfonic acid.

[0020] Fifth, the cushioning rubber pads that are glued and fixed to the upper surface of the legs allow for flexible contact between the legs and the ground, which can effectively prevent damage to the legs after long-term use. Attached Figure Description

The output shafts of drive motors 206 are fixed to the adjacent stirring paddles 205 via couplings. The rotation drive unit includes driven gears 207 fixedly sleeved on the lower end of the reaction tank 201 and the upper end of the cooling tank 202. L-shaped seats 208 are provided on both the upper and lower sides of the partition plate 105. Drive gears 209 are rotatably mounted on the L-shaped seats 208 via rotating shafts. The drive gears 209 are meshed with the adjacent driven gears 207. A dual-shaft motor 210 is installed in the mounting groove on the partition plate 105. The output shaft of the dual-shaft motor 210 is fixed to the adjacent rotating shaft via couplings.

[0030] like Figure 2 ,4 As shown, the filtration and cleaning module includes a clearance groove 306 on the outside of the filter box 101. A guide rail 301 is installed inside the filter box 101. A sliding seat 302 is slidably mounted on the outside of the guide rail 301. A rotating seat 303 is located at the bottom of the sliding seat 302. A filter cylinder 304 is rotatably mounted inside the rotating seat 303. A connecting port on the rotating seat 303 is connected to the discharge pipe 107 via a flexible hose. The outer arc surface of the filter cylinder 304 has evenly distributed perforations 305. The filter cylinder 304 is installed in conjunction with the clearance groove 306. Evenly distributed nozzles 310 are mounted on the top of the filter box 101 via a mounting bracket 309. A water storage tank 311 is mounted on the upper surface of the filter box 101. The nozzles 310 are all connected to the water storage tank 311 via connecting water pipes. The upper surface of the filter box 101 has openings for connecting... The filter box 101 is equipped with a through hole for water pipe connection and an electrically controlled oscillation unit for driving the filter cylinder 304 to reciprocate. The filter box 101 is also equipped with a driven rotation unit for driving the filter cylinder 304 to rotate. The driven rotation unit includes a driven gear 313 fixedly sleeved on the outer arc surface of the filter cylinder 304. A rack plate 312 is provided at the top of the inside of the filter box 101 through a support. The rack plate 312 is meshed with the driven gear 313. The electrically controlled oscillation unit includes an adjusting screw 307 rotatably disposed on the upper side inside the filter box 101. A drive seat 308 is threadedly connected to the outer side of the adjusting screw 307. The drive seat 308 is rotatably connected to the outer arc surface of the filter cylinder 304. A drive motor 314 is provided at the rear side of the filter box 101. The output shaft of the drive motor 314 is fixed to the adjusting screw 307 through a coupling.

[0031] like Figure 1 As shown, a control board 401 is provided on the front side of the filter box 101. Solenoid valve 1, solenoid valve 2, solenoid valve 3, heating module 203, cooling module 204, drive motor 1 206, dual-axis motor 210, nozzle 310 and drive motor 2 314 are all electrically connected to the control board 401.

[0032] During the production of aminosulfonic acid crystals, the solenoid valve is operated by the control board 401 to open the feed pipe 104. Then, a certain amount of urea, fuming sulfuric acid and a certain amount of additives are added into the feed pipe 104 in proportion. The raw materials entering the feed pipe 104 fall into the interior of the reaction tank 201 under the action of gravity.

[0033] The control panel 401 regulates the operation of the heating module 203, cooling module 204, drive motor 206, and dual-shaft motor 210. The heating module 203 controls the internal heating of the reaction tank 201, while the cooling module 204 controls the internal cooling of the cooling tank 202. The output shaft of drive motor 206 drives the connected stirring paddle 205 to rotate. The output shaft of dual-shaft motor 210 drives its connected rotating shafts to rotate in both forward and reverse cycles, with the angle of the rotating shafts being less than 150 degrees. This causes the drive gear 209 to drive its meshing driven gear 207 to rotate, resulting in the reciprocating rotation of the reaction tank 201 and the cooling tank 202. A certain amount of urea, fuming sulfuric acid, and a certain amount of additives react in the reaction... When the reaction tank 201 is heated by the heating module 203, the reciprocating rotation of the reaction tank 201 and the rotation of the stirring paddle 205 inside the reaction tank 201 accelerate the formation of the solution. The control panel 401 regulates the operation of the solenoid valve 2, so that the reacted solution enters the interior of the cooling tank 202 through the delivery pipe 106 and is cooled by the cooling module 204 inside the cooling tank 202. The reciprocating rotation of the cooling tank 202 and the rotation of the stirring paddle 205 inside the cooling tank 202 cause aminosulfonic acid crystals to be generated inside the cooling tank 202. Through the reciprocating rotation of the reaction tank 201 and the cooling tank 202 and the rotating stirring paddle 205 inside the reaction tank 201 and the cooling tank 202, aminosulfonic acid solution and aminosulfonic acid crystals can be produced quickly, stably and continuously.

[0034] The control panel 401 regulates the operation of the nozzle 310 and the second drive motor 314, causing the output shaft of the second drive motor 314 to drive the adjusting screw 307 connected to it to rotate in both forward and reverse cycles. This, in turn, adjusts the threaded relationship between the screw 307 and the drive seat 308, causing the drive seat 308 to drive the filter cylinder 304 to continuously reciprocate under the guidance of the sliding seat 302 and the guide rail 301. During this reciprocating motion, the meshing relationship between the rack plate 312 and the driven gear 313 causes the driven gear 313 to rotate, which in turn drives the filter cylinder 304 to rotate between the rotating seat 303 and the drive seat 308. This continuous reciprocating motion causes the filter cylinder 304 to rotate on its own. The nozzle 310 draws water from the storage tank 311 through the connected water pipe and sprays it onto the filter cylinder 304. The control panel 401 regulates the operation of the third solenoid valve, allowing the aminosulfonic acid crystals and mother liquor to enter the filter through the telescopic hose. Inside the filter cylinder 304, the mother liquor and aminosulfonic acid crystals enter and move within the rotating filter cylinder 304 as it reciprocates. This causes the mother liquor to leak through the holes 305 on the filter cylinder 304, while the aminosulfonic acid crystals roll downwards within the tilted filter cylinder 304. During this movement, the water jet sprayed by the nozzle 310, combined with the rotating filter cylinder 304, effectively filters and washes the aminosulfonic acid crystals. After washing, the aminosulfonic acid crystals roll out from the lower right end of the filter cylinder 304, achieving continuous production of aminosulfonic acid crystals. When filtering the aminosulfonic acid crystals from the mother liquor through the filter cylinder 304, pure water is sprayed into the filter cylinder 304 through the nozzle 310. The continuous reciprocating motion of the rotating filter cylinder 304 ensures that the aminosulfonic acid crystals are quickly and evenly washed to remove impurities, effectively increasing the efficiency of continuous crystallization production of aminosulfonic acid.

[0035] According to another embodiment of the present invention, Figure 1 , 5 As shown, the lower surface of the filter box 101 is provided with evenly distributed support legs 102, and each support leg 102 has a cushioning rubber pad glued and fixed to its lower surface. During use, the cushioning rubber pads glued and fixed to the lower surface of the support legs 102 allow for flexible contact between the support legs 102 and the ground, thereby effectively preventing damage to the support legs 102 after prolonged use.

[0036] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.

10. A process for realizing continuous crystallization of sulfamic acid, characterized in that: The following methods are included: S1. When producing sulfamic acid crystals, the control panel (401) is used to control the operation of the electromagnetic valve to open the feed pipe (104), and then a certain amount of urea and oleum and a certain amount of auxiliary agent are added into the feed pipe (104) in proportion. The raw materials entering the feed pipe (104) fall into the interior of the reaction barrel (201) under the action of gravity; S2, the control panel (401) controls the operation of the heating module (203), the cooling module (204), the driving motor 1 (206) and the dual-axis motor (210), so that the heating module (203) controls the internal heating and temperature rise of the reaction barrel (201), and the cooling module (204) controls the internal cooling and temperature drop of the cooling barrel (202), the output shaft of the driving motor 1 (206) drives the stirring paddle (205) connected thereto to rotate, and the output shaft of the dual-axis motor (210) drives the rotating shaft connected thereto to rotate in a forward and reverse cycle, and the angle of the rotating shaft is less than one hundred and fifty degrees, so that the driving gear (209) drives the driven gear 1 (207) meshing therewith to rotate, so that the reaction barrel (201) and the cooling barrel (202) rotate forward and reverse reciprocatingly; S3, when a certain amount of urea and oleum and a certain amount of auxiliary agent are heated by the heating module (203) in the reaction barrel (201), the reaction barrel (201) is reciprocated and the stirring paddle (205) in the reaction barrel (201) is rotated to accelerate the formation of a solution, and the control panel (401) controls the operation of the second solenoid valve so that the solution formed by the reaction enters the interior of the cooling barrel (202) from the delivery pipe (106) and is cooled by the cooling module (204) in the cooling barrel (202). The reciprocating rotation of the cooling barrel (202) and the rotation of the stirring paddle (205) in the cooling barrel (202) cause aminosulfonic acid crystals to be generated in the cooling barrel (202); S4, the control panel (401) regulates the operation of the nozzle (310) and the second drive motor (314), so that the output shaft of the second drive motor (314) drives the adjusting screw (307) connected thereto to rotate in a forward and reverse cycle, and then, through the threaded relationship between the adjusting screw (307) and the driving seat (308), the driving seat (308) drives the filter cartridge (304) to continuously swing back and forth under the guidance of the sliding seat (302) and the guide rail (301), and the filter cartridge (304) moves back and forth. During the reciprocating shaking process, the meshing relationship between the rack plate (312) and the second driven gear (313) drives the second driven gear (313) to rotate, so that the second driven gear (313) drives the filter cartridge (304) to rotate between the rotating seat (303) and the driving seat (308), so that the filter cartridge (304) continuously rotates itself during the reciprocating shaking process, and the spray head (310) absorbs water in the water storage barrel (311) through the connected water pipe and sprays the water toward the filter cartridge (304); S5, the control panel (401) controls the operation of the electromagnetic valve 3, so that the aminosulfonic acid crystals and the mother liquor enter the interior of the filter cartridge (304) from the telescopic hose. The mother liquor and the aminosulfonic acid crystals entering the filter cartridge (304) move in the filter cartridge (304) which is constantly rotating by itself during the back-and-forth shaking process, so that the mother liquor leaks out from the leakage hole (305) on the filter cartridge (304) and the aminosulfonic acid crystals roll downward in the inclined filter cartridge (304). During the movement of the aminosulfonic acid crystals, the aminosulfonic acid crystals are filtered and washed by the cooperation of the water column sprayed by the nozzle (310) and the filter cartridge (304) which is constantly rotating by itself during the back-and-forth shaking process. The washed aminosulfonic acid crystals roll out from the lower right end of the filter cartridge (304), thereby realizing the continuous production of aminosulfonic acid crystals.
