Description

Technical Field

[0001] The present invention relates to the technical field of chemical production, and specifically to an energy-saving stirring device for the chemical production of p-methylsulfonyltoluene. Background Art

[0002] In the chemical production system of p-methylsulfonyltoluene, the stirring device, as the core equipment for driving chemical reactions and achieving uniform mixing of materials, its performance directly affects production efficiency and product quality. Since production raw materials and intermediate products often exist in the form of large particles or lumps, where the lumping is due to long-term stacking and storage or moisture, the prior art usually adds a crushing process to refine the materials to increase the contact area of reactants, thereby accelerating the reaction process and improving the overall production efficiency.

[0003] However, when the materials enter the crushing area, they are extremely prone to stacking and jamming at the feed inlet, resulting in frequent arching and blockage of the hopper, and further causing problems such as unsmooth feeding and uneven discharging. Once blockage occurs, the equipment is forced to stop, and it is necessary to rely on manual cleaning or other dredging means to resume operation. This not only greatly reduces the equipment production capacity but also generates additional energy consumption due to equipment restart. After the material blockage occurs, the crushing components cannot normally crush and convey the materials, and the motor is still continuously outputting power, which is equivalent to the motor having to overcome greater resistance to maintain operation, which will cause a sharp increase in the load of the motor and is likely to cause damage to the motor.

[0004] Secondly, during the crushing process, the crushing rollers in the crushing area achieve crushing by applying mechanical pressure to the materials. This process is accompanied by heat generation, and the physical properties of the materials change under the influence of temperature and pressure changes, and the viscosity increases significantly. At the same time, the concave-convex structure designed on the surface of the crushing rollers to enhance the crushing effect further increases the contact area with the materials, providing more sites for material adhesion, resulting in the crushed materials being extremely prone to adhering to the roller surface. As the adhered materials accumulate continuously, the effective crushing area of the crushing rollers continues to shrink, and the crushing efficiency decreases accordingly, resulting in new incoming materials being difficult to be fully crushed, seriously affecting the stability of product quality. In addition, to remove the adhered materials, the equipment needs to be shut down for regular maintenance, which not only interrupts the production process and reduces the equipment utilization rate but also generates additional energy consumption.

[0005] Therefore, an energy-saving stirring device for the chemical production of p-methylsulfonyltoluene is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide an energy-saving stirring device for the chemical production of p-methylsulfonyltoluene to solve the problems raised in the above background art.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: an energy-saving stirring device for the chemical production of p-methylsulfonyltoluene, comprising a crushing box and a stirring box, wherein the stirring box is fixedly connected to the bottom of the crushing box, a bracket is fixedly connected to the outer wall of the crushing box, two energy-saving motors are installed on the bracket, the inner wall of the crushing box is rotatably connected to two crushing rollers, the crushing box is provided with a production auxiliary component, the production auxiliary component comprises a slide plate, the slide plate is slidably connected to one side of the crushing box close to the bracket, a square rod is fixedly connected to the bottom of one end of the slide plate passing through the outside of the crushing box, an arc plate is fixedly connected to the bottom end of the square rod, a spring is sleeved on the square rod, and a connecting plate is fixedly connected to the end of the slide plate passing through the inside of the crushing box, a blanking plate is fixedly connected to each of the two ends of the connecting plate, and a cam is fixedly connected to each of the output shafts of the two energy-saving motors.

[0008] Furthermore, the inner wall of the crushing box is symmetrically rotatably connected to two rollers, and a plurality of rubber scrapers are respectively arranged on the two rollers in a circular array. The inner wall of the crushing box is symmetrically fixedly connected to two fixed plates, and a staggered tooth plate is fixedly connected to each end of the two fixed plates close to each other. The two rollers pass through the crushing box in the direction of the bracket, and a belt one is transmission-connected between the two rollers and the output shaft of the energy-saving motor that is far away from each other. The inner side wall of the crushing box near the bottom is rotatably connected to a shaft bevel gear one, which passes through the crushing box, and a belt two is transmission-connected between the end of the shaft bevel gear one that passes through the crushing box and the output shaft of the energy-saving motor. The inner wall of the crushing box is fixedly connected to a support rod, and the end of the support rod away from the belt two is fixedly connected to a protection box, and the bottom of the protection box is rotatably connected to a shaft bevel gear two, and the shaft bevel gear two is evenly and fixedly connected to a plurality of stirring paddles.

[0009] Furthermore, both crushing rollers pass through the crushing box and are fixedly connected to the output shafts of the energy-saving motors at corresponding positions.

[0010] Furthermore, both ends of the slide plate pass through the crushing box, the square rod is slidably connected to the bracket, and both ends of the spring are fixedly connected to the lower surface of the slide plate and the top surface of the bracket respectively.

[0011] Furthermore, the arc plate is located on the rotation path of the two cams, the raised ends of the two cams face the same direction, and the two blanking plates are both inclined.

[0012] Furthermore, the rubber scraper contacts the crushing roller, and the rubber scraper is provided with through grooves distributed in a linear array, and the staggered tooth plate is provided with a plurality of long strips corresponding to the positions of the through grooves of the rubber scraper.

[0013] Furthermore, the staggered tooth plate is located at the bottom of the rubber scraper, and the staggered tooth plate is inserted into the rubber scraper, and one end of the staggered tooth plate close to the rubber scraper is inclined downward, and the two belts are arranged crosswise.

[0014] Furthermore, the bevel gear with shaft two is located at the center of the circular shape of the mixing tank. One end of the bevel gear with shaft one and the bevel gear with shaft two that are close to each other are meshed with each other, and both the bevel gear with shaft one and the bevel gear with shaft two are rotatably connected to the protection box.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By generating vibrations in the vertical direction of the two blanking plates, the vibrations will be applied to the materials stacked on the two blanking plates, which can effectively prevent the materials from stacking and pressing on each other at the feed inlet, prevent arching and blocking of the blanking port, ensure smooth feeding and uniform blanking of the equipment, reduce the number of shutdowns caused by material blockage, reduce energy consumption, and also reduce the increase in the motor load caused by material blockage and even the situation of motor damage.

[0016] By the reverse rotation of the rubber scraper and the crushing roller, the materials adhered to the surface of the crushing roller due to factors such as changes in physical properties and the surface structure of the crushing roller are actively scraped off, effectively preventing the materials from accumulating on the surface of the crushing roller, solving the problems of the reduction of the effective crushing area of the crushing roller and the decrease of the crushing efficiency, ensuring sufficient crushing of the materials, ensuring the stability of the product quality, enabling the equipment to not need to be shut down regularly for cleaning the adhered materials, solving the problems of the interruption of the production process and energy waste caused by shutdown cleaning in the prior art, ensuring the continuous operation of the equipment, and improving the utilization rate of the equipment.

[0017] At the same time, the residues on the rubber scraper after scraping the crushing roller are scraped off by the staggered tooth plate, and the substances scraped off by the staggered tooth plate fall along the inclined plane into the mixing tank, which can keep the rubber scraper clean in real time, prevent the materials from accumulating on the rubber scraper, enable the rubber scraper to always scrape the crushing roller in a good state, continuously and efficiently clean the materials adhered to the surface of the crushing roller, ensure the effective crushing area of the crushing roller, and maintain the crushing efficiency.

[0018] The qualified-size materials are efficiently stirred and mixed by the stirring paddle, promoting the mixing reaction, ensuring the stability and consistency of the product quality, and improving the production efficiency.

[0019] At the same time, steps such as vibration, scraping, and stirring are all driven by two energy-saving motors, that is, only two energy-saving motors are used to achieve additional operations except for crushing, avoiding the energy loss caused by the independent operation of more driving devices, effectively reducing the energy consumption of the entire device, meeting the design requirements of the energy-saving mixing device, and helping to reduce the production cost.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiments provided by the present invention: Please refer to Figures 1 to 10As shown in the figure, an energy-saving stirring device for the chemical production of p-methylsulfonyltoluene includes a crushing box 11 and a stirring box 12. The stirring box 12 is fixedly connected to the bottom of the crushing box 11. A bracket 13 is fixedly connected to the outer wall of the crushing box 11.

[0024] Among them: the crushing box 11, the stirring box 12, the bracket 13, the energy-saving motor 14, and the crushing roller 15 are all existing known technologies and will not be elaborated too much.

[0025] Specifically: Driven by the two energy-saving motors 14, the two crushing rollers 15 rotate towards each other, that is, the two crushing rollers 15 move the material towards the center direction of the two crushing rollers 15 and crush it.

[0026] More specifically: The crushing box 11, the stirring box 12, the bracket 13, the energy-saving motor 14, and the crushing roller 15 are used for the chemical production of p-methylsulfonyltoluene here. Specifically: Crush and stir the materials required in the chemical production of p-methylsulfonyltoluene.

[0027] Furthermore: The crushing box 11 is set to be square. The square shape enables the two crushing rollers 15 to better cover the crushing range. The top of the crushing box 11 is a feed inlet. The stirring box 12 is set to be cylindrical. The cylindrical shape enables the crushed materials that meet the size requirements in the cavity of the stirring box 12 to be better stirred. A circular storage plate is detachably connected to the bottom of the stirring box 12 through bolts, that is, a discharge port is reserved at the bottom of the stirring box 12. This discharge port is opened and closed by the circular storage plate. The circular storage plate is detachably connected to the bottom of the stirring box 12 through bolts.

[0028] The crushing box 11 is provided with a production auxiliary component, which includes a slide plate 21, which is slidably connected to one side of the crushing box 11 close to the bracket 13, and both ends of the slide plate 21 pass through the crushing box 11. A square rod 22 is fixedly connected to the bottom of one end of the slide plate 21 passing through the outside of the crushing box 11, and an arc plate 23 is fixedly connected to the bottom of the square rod 22. The square rod 22 is slidably connected to the bracket 13, and a spring 24 is sleeved on the square rod 22. The two ends of the spring 24 are respectively fixedly connected to the lower surface of the slide plate 21 and the top surface of the bracket 13. The end of the slide plate 21 that passes into the crushing box 11 is fixedly connected to a connecting plate 25, and the two ends of the connecting plate 25 are respectively fixedly connected to a blanking plate 26. A cam 27 is fixedly connected to each of the output shafts of the two energy-saving motors 14. The inner wall of the crushing box 11 is symmetrically rotatably connected to two rollers 29, and a plurality of rubber scrapers 210 are each arranged in a ring array on the two rollers 29. The inner wall of the crushing box 11 Two fixed plates 211 are symmetrically fixedly connected, and one end of the two fixed plates 211 close to each other is fixedly connected with a staggered tooth plate 212, and the two rollers 29 pass through the crushing box 11 in the direction of the bracket 13, and the ends of the two rollers 29 passing through the crushing box 11 are respectively connected with the output shaft of the energy-saving motor 14 away from each other by a belt 1 213, and the inner wall of the crushing box 11 near the bottom is rotatably connected with a shaft bevel gear 1 214, and the shaft bevel gear 1 214 passes through the crushing box 11, and the end of the shaft bevel gear 1 214 passing through the crushing box 11 is connected with the output shaft of the energy-saving motor 14 by a belt 2 215, and the inner wall of the crushing box 11 is fixedly connected with a support rod 216, and the end of the support rod 216 away from the belt 2 215 is fixedly connected with a protection box 217, and the bottom of the protection box 217 is rotatably connected with a shaft bevel gear 2 218, and the shaft bevel gear 218 is evenly and fixedly connected with a plurality of stirring paddles 28.

[0029] Among them: Reference Figure 10 As shown, the arc plate 23 is located on the rotation path of the two cams 27, and the raised ends of the two cams 27 face the same direction. Specifically, the two cams 27 are driven by the output shafts of the two energy-saving motors 14 and also rotate in opposite directions, that is, the two cams 27 can alternately abut the arc plate 23.

[0030] It should be noted that: when the spring 24 does not undergo elastic deformation, Figure 10 In the state shown in , the arc plate 23 is in the highest position, at which time the arc plate 23 does not contact the output shaft of the energy-saving motor 14, that is, the position of the arc plate 23 will not affect the normal rotation of the output shaft of the energy-saving motor 14.

[0031] Among them: Reference Figure 6As shown, the two unloading plates 26 are both inclined, specifically: the top ends of the two unloading plates 26 are far away from each other. The bottom ends of the two unloading plates 26 are close to each other. The two unloading plates 26 are used as unloading guides for the crushing box 11. The two unloading plates 26 are responsible for guiding the materials fed from the top feed port of the crushing box 11 to the center position of the two crushing rollers 15, that is, the crushing area of the two crushing rollers 15.

[0032] It should be added that: a side of the crushing box 11 away from the bracket 13 is provided with an openable box door, which is used to facilitate the user to operate the inside of the crushing box 11.

[0033] Among them: Reference Figure 8 and Figure 10 As shown, and refer to Figure 10 In terms of the positional relationship in the figure, the two belts 213 are cross-arranged, specifically: the two rollers 29 are respectively connected to the output shafts of the diagonally opposite energy-saving motors 14 through the belt 213, that is, the two rollers 29 are respectively in the same rotation direction as the output shafts of the diagonally opposite energy-saving motors 14. Combined with the supplement that the output shafts of the two energy-saving motors 14 rotate in opposite directions, it can be known that as the two energy-saving motors 14 rotate, the energy-saving motors 14 drive the rollers 29 to rotate through the belt 213. At this time, the rollers 29 rotate in opposite directions to the crushing rollers 15 corresponding to the vertical direction.

[0034] Among them: Reference Figure 7 As shown, the rubber scraper 210 is in conflict with the crushing roller 15. Specifically, when the crushing roller 15 rotates, the rubber scraper 210 is driven by the roller shaft 29 to rotate in the opposite direction to the crushing roller 15. At this time, the rubber scraper 210 is in conflict with the crushing roller 15 to scrape off the material adhered to the crushing roller 15.

[0035] It is necessary to add: refer to Figure 7 As shown, the rubber scraper 210 is provided with through grooves distributed in a linear array, and the staggered tooth plate 212 is provided with a plurality of long strips corresponding to the positions of the through grooves of the rubber scraper 210, that is, the rubber scraper 210 is matched with the staggered tooth plate 212. The staggered tooth plate 212 is located at the bottom of the rubber scraper 210, and the staggered tooth plate 212 is inserted into the rubber scraper 210, and the end of the staggered tooth plate 212 close to the rubber scraper 210 is tilted downward. Combined with the above supplement to the scraping effect of the rubber scraper 210, it can be known that as the rubber scraper 210 rotates, the staggered tooth plate 212 scrapes the residual material on the rubber scraper 210 after scraping the crushing roller 15, and the material scraped by the staggered tooth plate 212 falls along the inclined surface to the inside of the mixing box 12.

[0036] Among them: Reference Figure 3 , Figure 5 , Figure 6 , Figure 8As shown in the figure, combined with the cylindrical shape of the mixing tank 12, the bevel gear with shaft two 218 is located at the center of the circular shape of the mixing tank 12. One end of the bevel gear with shaft one 214 close to the bevel gear with shaft two 218 meshes with each other, and both the bevel gear with shaft one 214 and the bevel gear with shaft two 218 are rotatably connected to the protection box 217. The functions of the protection box 217 are: to provide a support point for the bevel gear with shaft two 218, and to exist as a protective shell, covering the meshing part of the bevel gear with shaft one 214 and the bevel gear with shaft two 218, preventing the meshing of the bevel gear with shaft one 214 and the bevel gear with shaft two 218 from being interfered by the falling materials.

[0037] In the initial state of the production auxiliary component, that is, when the materials required for the chemical production of p-toluenesulfonyl chloride are not crushed and stirred, the states of each structure inside the production auxiliary component are as follows: The spring 24 does not produce elastic deformation, the slide plate 21 is at the highest position of the sliding connection with the crushing box 11, and the arc plate 23 does not contact the two cams 27.

[0038] When the production auxiliary component is running, that is, when it is necessary to crush and stir the materials required for the chemical production of p-toluenesulfonyl chloride, at this time, the user starts the two energy-saving motors 14, so that the output ends of the two energy-saving motors 14 drive the two crushing rollers 15 to rotate towards each other. And the user inputs materials into the crushing box 11 from the top position of the crushing box 11. The input materials are guided by the two feeding plates 26 and moved to the two crushing rollers 15. The materials are crushed by the two crushing rollers 15 and fall downward. The materials falling downward enter the cavity of the mixing tank 12.

[0039] At the same time as the output shafts of the two energy-saving motors 14 rotate, the output shafts of the two energy-saving motors 14 drive the obliquely opposite roller shafts 29 to rotate through the belt one 213. Then the two roller shafts 29 drive the rubber scraping plates 210 on them to rotate. It should be noted that: at this time, the rotation direction of the roller shaft 29 is opposite to that of the corresponding crushing roller 15 in the vertical direction. While the rubber scraping plate 210 rotates, it contacts the crushing roller 15 and scrapes off the substances adhered to the crushing roller 15. And as the rubber scraping plate 210 rotates, the staggered tooth plate 212 scrapes off the substances remaining on the rubber scraping plate 210 after scraping the crushing roller 15. At the same time, the substances scraped off by the staggered tooth plate 212 fall downward along the inclined plane into the mixing tank 12.

[0040] The above is that the production auxiliary component removes the substances adhered to the crushing roller 15 and puts the removed adhered substances into the cavity of the mixing tank 12.

[0041] And as the crushing work progresses, since the input of materials is a continuous process, there is a situation where the materials are stacked and piled up on the two feeding plates 26. However, while the output shafts of the two springs 24 rotate, they drive the two cams 27 to rotate synchronously. Combining with the supplement in the above text that the two energy-saving motors 14 drive the two cams 27 to rotate towards each other, at this time, the two cams 27 alternately contact the arc plate 23. Refer to Figure 10 As shown, when the cam 27 contacts the arc plate 23, it will exert a downward pressure on the arc plate 23, causing the arc plate 23 to drive the slide plate 21 to move downward through the square rod 22. At this time, the square rod 22 slides downward within the bracket 13, and the spring 24 undergoes elastic deformation. The slide plate 21 will move downward inside the crushing box 11, and then the connecting plate 25 connected to the slide plate 21 moves downward synchronously, and the two feeding plates 26 connected to the connecting plate 25 move downward synchronously.

[0042] When the two cams 27 rotate to a position where they no longer contact the arc plate 23, at this time, under the elastic stretching action of the spring 24, the spring 24 pushes the slide plate 21 to move upward inside the crushing box 11. And as the slide plate 21 moves upward, the square rod 22 and the arc plate 23 are driven to move upward synchronously, and the slide plate 21 drives the two feeding plates 26 to move upward through the connecting plate 25.

[0043] With the continuous rotation of the output shaft of the energy-saving motor 14, the two feeding plates 26 can be cyclically moved up and down, that is, vibrations are generated in the vertical direction of the two feeding plates 26, and the vibrations are applied to the materials stacked and piled up on the two feeding plates 26.

[0044] The above is that the production auxiliary components vibrate the input materials, so that the stacked and piled materials are evenly distributed under the action of the vibration to achieve the purpose of uniform feeding, and this is used as a cycle.

[0045] After the materials enter the inside of the mixing box 12, with the rotation of the output shaft of the energy-saving motor 14, the output shaft of the energy-saving motor 14 drives the belt shaft bevel gear one 214 to rotate synchronously through the second belt 215. While the belt shaft bevel gear one 214 rotates, the belt shaft bevel gear one 214 meshes with and drives the belt shaft bevel gear two 218 to rotate synchronously. At this time, both the belt shaft bevel gear one 214 and the belt shaft bevel gear two 218 rotate on the protection box 217. And while the belt shaft bevel gear two 218 rotates, the belt shaft bevel gear two 218 drives the uniformly arranged stirring paddles 28 on it to rotate synchronously. While the stirring paddles 28 rotate, they can stir the materials falling into the cavity of the mixing box 12.

[0046] Through the operation of the above production auxiliary components, the following effects can be achieved: By generating vibrations in the vertical direction of the two blanking plates 26, the vibrations will be applied to the materials stacked and pressed on the two blanking plates 26, which can effectively avoid the stacking and pressing of materials at the feed inlet, prevent arching and blocking of the blanking port, ensure smooth feeding and uniform blanking of the equipment, reduce the number of shutdowns caused by material blockage, reduce energy consumption, and also reduce the increase in motor load caused by material blockage and even the situation of motor damage.

[0047] By the rubber scraper 210 rotating in the opposite direction to the crushing roller 15, it actively scrapes the materials adhered to the surface of the crushing roller 15 due to factors such as changes in physical properties and the surface structure of the crushing roller 15, effectively avoiding the accumulation of materials on the surface of the crushing roller 15, solving the problems of reduction in the effective crushing area and decrease in crushing efficiency of the crushing roller 15, ensuring sufficient crushing of materials, ensuring stable product quality, enabling the equipment to not need to be shut down regularly for cleaning the adhered materials, solving the problems of interruption of the production process and energy waste caused by shutdown cleaning in the prior art, ensuring continuous operation of the equipment, and improving equipment utilization rate.

[0048] At the same time, the material remaining on the rubber scraper 210 after scraping the crushing roller 15 is scraped by the staggered tooth plate 212, and the material scraped by the staggered tooth plate 212 falls along the inclined plane into the inside of the mixing tank 12, which can keep the rubber scraper 210 clean in real time, prevent the accumulation of materials on the rubber scraper 210, enable the rubber scraper 210 to always scrape the crushing roller 15 in a good state, continuously and efficiently clean the materials adhered to the surface of the crushing roller 15, ensure the effective crushing area of the crushing roller 15, and maintain the crushing efficiency.

[0049] The qualified-sized materials are efficiently stirred and mixed by the stirring paddle 28 to promote the mixing reaction, ensure the stability and consistency of product quality, and improve production efficiency.

[0050] At the same time, steps such as vibration, scraping, and stirring are all driven by two energy-saving motors 14, that is, only two energy-saving motors 14 are used to achieve additional operations other than crushing, avoiding energy losses caused by the independent operation of more driving devices, effectively reducing the energy consumption of the entire device, meeting the design requirements of an energy-saving mixing device, and helping to reduce production costs.
