Description

Technical Field

[0001] The invention relates to the technical field of dimethylthiotoluenediamine production, and in particular to a production device and a production method of dimethylthiotoluenediamine. Background Art

[0002] Dimethylthiotoluenediamine is a yellow clear liquid at room temperature and is insoluble in water. Its main uses are to make curing agents, antioxidants, chain extenders, lubricants, etc. The production process of dimethylthiotoluenediamine is: the raw materials for producing dimethylthiotoluenediamine are added into a reactor, and a dimethylthiotoluenediamine solution is generated by reaction through stirring and mixing.

[0003] In the production process of dimethylthiotoluenediamine, since the production process requires the addition of aromatic amine catalysts, and aromatic amine catalysts and aromatic amine derivatives in the production process will affect the purity of the dimethylthiotoluenediamine solution, a reaction liquid is usually added to react with the aromatic amine catalyst and aromatic amine derivatives to generate substances insoluble in the dimethylthiotoluenediamine solution, and then the impurities are removed by solid-liquid separation to improve the purity of the dimethylthiotoluenediamine solution; therefore, the addition of the reaction liquid will cause impurities to adhere to the inner wall of the reactor and the stirring blades, and some impurities will remain in the dimethylthiotoluenediamine solution. In the process of discharging the solution, the impurities will be discharged together, increasing the subsequent process of separating the impurities from the solution. The traditional soaking and flushing methods cannot scrape off the thicker impurities on the inner wall of the reactor, and impurities are easily deposited on the stirring blades, resulting in solid impurities adhering to the inner wall of the reactor and the stirring blades for a long time, affecting the subsequent production of dimethylthiotoluenediamine.

The axis of the rectangular plate 5 parallel to the long side is perpendicular to the central axis of the rotating shaft 4. The rotating shaft 4 drives the rectangular plate 5 to rotate to accelerate the mixing speed of the materials in the mixing shell 2. An intercepting net 6 is arranged at the lower part of the mixing shell 2. Impurities are intercepted by the intercepting net 6 to avoid the impurities being discharged together with the materials, thereby eliminating the subsequent separation process of the materials and impurities. A second discharge port 203 is arranged at the right part of the lower surface of the mixing shell 2. The second discharge port 203 is used to discharge impurities on the intercepting net 6. An electromagnetic valve electrically connected to the control terminal is arranged in the second discharge port 203. The rotating shaft 4 is provided with a cleaning mechanism for scraping impurities on the inner wall of the mixing shell 2.

[0034] like Figure 4As shown, the cleaning mechanism includes two fixed sleeves 701 symmetrically distributed on the left and right, and the two fixed sleeves 701 are fixedly connected to the upper part of the rotating shaft 4. Symmetrically distributed sliders 702 are slidably connected in the fixed sleeves 701, and the symmetrically distributed sliders 702 are fixedly connected to slide bars 703. The slide bars 703 are located in the middle of the fixed sleeves 701, and the end of the slide bar 703 away from the rotating shaft 4 is fixedly connected to a fixed tube 704, and the side of the fixed tube 704 close to the inner wall of the mixing shell 2 is rotatably connected to a rotating rod 705, and the lower end of the rotating rod 705 is fixedly connected to a scraper 706 for scraping impurities on the inner wall of the mixing shell 2. The scraper 706 is set in a diamond shape and is used to scrape impurities on the inner wall of the mixing shell 2. There is a gap between the scraper 706 and the inner wall of the mixing shell 2 to avoid long-term friction between the scraper 706 and the inner wall of the mixing shell 2 and damage to the scraper 706. The mixing shell 2 is provided with a scraping component for cleaning impurities on the scraper 706.

[0035] like Figure 2 , Figure 4 and Figure 5 As shown, the scraping component includes an electric push rod 801, which is fixed to the right part of the upper surface of the mixing shell 2 through a support frame, and is electrically connected to the control terminal. The telescopic end of the electric push rod 801 is slidably connected to the mixing shell 2, and the telescopic end of the electric push rod 801 is fixed with a U-shaped block 802, and the left side of the U-shaped block 802 is fixed with a fixed ring 803. The inner side surface of the fixed ring 803 is rotatably connected with a rotating ring 804, and the inner side surface of the rotating ring 804 is fixed with two scraping blocks 805 symmetrically distributed on the left and right. The scraping block 805 is provided with a diamond groove, and the scraping block 805 cooperates with the scraper 706. The scraping block 805 moves downward and is sleeved on the scraper 706 to scrape off impurities on the outer side of the scraper 706. The scraping block 805 is provided with an adjustment component for adjusting the angle of adjacent scrapers 706, and the rotating shaft 4 is provided with a rotating component for rotating the rectangular plate 5.

[0036] like Figure 5 As shown, the adjustment assembly includes a telescopic rod 806, which is fixed to the inner side of the scraper block 805. The rotating rod 705 is provided with a guide groove 7051 that cooperates with the adjacent telescopic rod 806. The upper and lower parts of the guide groove 7051 are vertical grooves, and the middle part of the guide groove 7051 is an inclined groove. The telescopic rod 806 slides along the guide groove 7051 to rotate the adjacent rotating rod 705.

[0037] like Figure 6-Figure 8As shown, the rotating component includes two connecting shafts 901 distributed at equal intervals up and down, and the two connecting shafts 901 are both rotatably connected to the rotating shaft 4. The rear end of the connecting shaft 901 is fixedly connected to the front side of the adjacent rectangular plate 5. The rotating shaft 4 is provided with a rectangular cavity 402 located in front of the card slot 401. The front end of the connecting shaft 901 is fixedly connected to a gear 902 located in the rectangular cavity 402. A torsion spring 903 is fixedly connected between the rear side of the gear 902 and the rotating shaft 4. The rotating shaft 4 is slidably connected to a rack 904 located in the rectangular cavity 402. The rack 904 is meshed with the two gears 902. The rack 904 moves downward to drive the two gears 902 to rotate, and the gear 902 drives the rectangular plate 5 to rotate through the connecting shaft 901. The plate 5 rotates, and the rectangular plate 5 gradually gets stuck in the adjacent slot 401. The upper end of the rack 904 is fixedly connected with a first L-shaped rod 905. A limiting groove 403 is arranged on the front side of the upper part of the rotating shaft 4. The first L-shaped rod 905 is slidably connected with the limiting groove 403. The end of the first L-shaped rod 905 away from the rack 904 is fixedly connected with a first magnet block 906. The rotating shaft 4 is spline-connected with a scraper ring 907 that cooperates with the first L-shaped rod 905. The scraper ring 907 is fixedly connected with two connecting rods 908 that are symmetrically distributed on the left and right. The end of the connecting rod 908 away from the scraper ring 907 is fixedly connected to the adjacent scraper block 805. The front side of the upper surface of the scraper ring 907 is fixedly connected with a second magnet block 909 that cooperates with the first magnet block 906.

[0038] When it is necessary to use the device to produce dimethylthiotoluenediamine, the operator first adds the raw material of dimethylthiotoluenediamine into the mixing shell 2 through the feed port 201. The "raw material of dimethylthiotoluenediamine" is referred to as "material" below. The height of the added material is less than the height of the scraper 706. After the material is added, the operator starts the servo motor 3 through the control terminal. The output shaft of the servo motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the rectangular plate 5 to rotate. The rotating shaft 4 drives the two fixed sleeves 701 to rotate. The fixed sleeve 701 drives the rotating rod 705 to rotate through the slider 702, the slide bar 703 and the fixed tube 704. The rotating rod 705 drives the scraper 706 to rotate. The rectangular plate 5 and the scraper 706 rotate to accelerate the mixing speed of the material in the mixing shell 2.

[0039] During the rotation of the rotating shaft 4, the rotating shaft 4 drives the connecting rod 908 to rotate through the scraper ring 907, the connecting rod 908 drives the scraper block 805 to rotate, the scraper block 805 drives the rotating ring 804 and the telescopic rod 806 to rotate, the scraper block 805 and the rotating rod 705 rotate synchronously, and the telescopic rod 806 is stuck in the upper part of the guide groove 7051 to limit the rotating rod 705, so the rotating rod 705 and the scraper plate 706 will not rotate in the process of rotating around the rotating shaft 4 as the rotation center. Impurities will be generated during the mixing process of the materials, and the impurities will adhere to the inner wall of the mixing shell 2, the rotating shaft 4, the rectangular plate 5 and On the scraper 706, since the height of the material is less than the height of the scraper 706, impurities will not adhere to the scraper ring 907, the connecting rod 908 and the scraper block 805. During the rotation of the scraper 706, since there is a gap between the scraper 706 and the mixing shell 2, the scraper 706 continuously scrapes off the impurities attached to the inner wall of the mixing shell 2, so that the thickness of the impurities on the inner wall of the mixing shell 2 is equal to the width of the gap between the scraper 706 and the inner wall of the mixing shell 2, ensuring that the thickness of the impurities on the inner wall of the mixing shell 2 is always guaranteed to be within a certain width range, which is convenient for subsequent processing.

[0040] In the process of stirring the materials, in order to prevent impurities from adhering to the rotating shaft 4, the rectangular plate 5 and the scraper 706 for a long time, making it difficult to clean after the stirring is completed, it is necessary to regularly clean the impurities attached to the rotating shaft 4, the rectangular plate 5 and the scraper 706. The specific operation is as follows: the control terminal starts the electric push rod 801, the telescopic end of the electric push rod 801 drives the U-shaped block 802 to move downward, the U-shaped block 802 drives the fixed ring 803 to move downward, the fixed ring 803 drives the rotating ring 804 to move downward, the rotating ring 804 drives the two scraping blocks 805 to move downward, the scraping blocks 805 drive the two telescopic rods 806 to move downward, the telescopic rods 806 slide downward along the adjacent guide grooves 7051, and the telescopic rods 806 drive the adjacent rotating rods 705 clockwise under the guidance of the adjacent guide grooves 7051. The needle rotates, and the rotating rod 705 drives the scraper 706 to rotate clockwise. When the telescopic rod 806 is located at the lower part of the guide groove 7051, the scraper 706 rotates 90°. At this time, the distance between the scraper 706 and the inner wall of the mixing shell 2 increases, ensuring that the scraper block 805 is sleeved on the outside of the scraper 706. As the scraper block 805 continues to move downward, the scraper block 805 is gradually sleeved on the outside of the scraper 706. The scraper block 805 moves downward to scrape off the impurities on the outside of the scraper 706, reducing the accumulation of impurities on the scraper 706. The scraper 706 rotates, so that the resistance of the scraper 706 during the rotation process with the rotating shaft 4 as the rotation center is reduced, and the material in the mixing shell 2 during the rotation of the scraper 706 is increased. The flushing effect of the impurities falling off the scraper 706 by the material in the mixing shell 2 is increased, which facilitates the falling of impurities on the scraper 706.

[0041] In the process of the two scraper blocks 805 moving downward, the two scraper blocks 805 drive the scraper ring 907 to move downward through the adjacent connecting rod 908, the scraper ring 907 drives the second magnet block 909 to move downward, the second magnet block 909 drives the first magnet block 906 to move downward through the magnetic force, the first magnet block 906 drives the first L-shaped rod 905 to move downward, the crossbar part of the first L-shaped rod 905 slides downward from the upper part of the limiting groove 403, the first L-shaped rod 905 drives the rack 904 to move downward, the rack 904 drives the two gears 902 to rotate, and the torsion spring 903 in the power storage state is reset, so that Taking one gear 902 as an example, the gear 902 drives the rectangular plate 5 to rotate by connecting the shaft 901, and the rectangular plate 5 gradually rotates into the slot 401. During the rotation of the rectangular plate 5, the rectangular plate 5 pushes out the impurities in the slot 401, and the shaft 4 scrapes off the impurities on the front and back sides and the upper and lower sides of the rectangular plate 5. When the cross bar part of the first L-shaped rod 905 is located at the lowermost side of the limiting groove 403, the first L-shaped rod 905 is limited by the limiting groove 403 and cannot move downward. At this time, the rectangular plate 5 rotates 90°, and the rectangular plate 5 is completely inserted into the slot 401. The shaft 4 and the two rectangular plates 5 form a complete cylinder.

[0042] As the scraper ring 907 drives the second magnet block 909 to continue to move downward, the second magnet no longer drives the first magnet block 906 to move downward, and the torsion spring 903 is reset. The torsion spring 903 ensures that the rectangular plate 5 is stuck in the slot 401 to prevent the second magnet block 909 from no longer adsorbing the first magnet block 906 and the rectangular plate 5 from rotating out of the slot 401. In the process of the scraper ring 907 moving downward, the scraper ring 907 scrapes off the impurities on the outside of the rotating shaft 4 and the left and right sides of the rectangular plate 5, reducing the accumulation of impurities on the outside of the rotating shaft 4 and the left and right sides of the rectangular plate 5. When the scraper block 805 is at the bottom of the scraper plate 706, the scraper plate 706 and the outside of the rotating shaft 4 are All the impurities on the left and right sides of the rectangular plate 5 are scraped off, and then the control terminal controls the telescopic end of the electric push rod 801, so that the electric push rod 801 drives the U-shaped block 802 to move upward, and the scraper block 805 and the scraper ring 907 move upward. When the scraper block 805 is located at the upper part of the scraper 706, as the scraper block 805 continues to move upward, the telescopic rod 806 gradually gets stuck in the lower part of the guide groove 7051, and the telescopic rod 806 moves upward along the guide groove 7051. The telescopic rod 806 drives the rotating rod 705 to rotate counterclockwise, and the rotating rod 705 drives the scraper 706 to rotate counterclockwise. When the scraper 706 rotates 90° counterclockwise, the state of the scraper 706 is as follows Figure 4 As shown, the scraper 706 continues to scrape away impurities on the inner wall of the mixing housing 2.

[0043] During the upward movement of the scraper ring 907, the scraper ring 907 drives the second magnet block 909 to move upward. When the second magnet block 909 contacts the first magnet block 906, the first magnet block 906 and the second magnet block 909 generate suction, and the scraper ring 907 continues to move upward. The first magnet block 906 drives the first L-shaped rod 905 to move upward, and the first L-shaped rod 905 drives the rack 904 to move upward. The rack 904 drives the rectangular plate 5 to rotate through the two gears 902 and the connecting shaft 901. The two torsion springs 903 store force. When the scraper ring 907 returns to its initial position, the rectangular plate 5 is parallel to the axis of the long side. Perpendicular to the central axis of the rotating shaft 4, the rectangular plate 5 continues to stir the materials in the mixing shell 2. Subsequently, the operator cleans the impurities adhered to the rotating shaft 4, the rectangular plate 5 and the scraper 706 by regularly repeating the above operation to reduce the accumulation of impurities on the rotating shaft 4, the rectangular plate 5 and the scraper 706. In summary, when the impurities on the rotating shaft 4 are not cleaned, the rectangular plate 5 is perpendicular to the rotating shaft 4 to accelerate the mixing of materials in the mixing shell 2. When the impurities on the rotating shaft 4 need to be cleaned, the rectangular plate 5 is inserted into the rotating shaft 4, and the scraper ring 907 scrapes off the impurities on the rotating shaft 4, so as to facilitate the centralized treatment of the impurities on the rotating shaft 4 and the rectangular plate 5.

[0044] When the materials in the mixing shell 2 are mixed, the operator stops the servo motor 3, and the shaft 4 stops rotating. Then, the operator opens the solenoid valve in the first discharge port 202 through the control terminal. After the materials in the mixing shell 2 are screened by the interception net 6, the materials are discharged through the first discharge port 202. Impurities accumulate on the interception net 6, and the impurities are intercepted by the interception net 6 to avoid the impurities being discharged together with the materials, thus eliminating the need for the subsequent separation process of the materials and impurities. The operator collects the materials discharged from the first discharge port 202. When all the materials in the mixing shell 2 are discharged, the operator closes the solenoid valve in the first discharge port 202 through the control terminal. Then, the operator feeds the mixing shell 2 through the feed port 201. Cleaning liquid is added into the mixing shell 2. After the cleaning liquid is added, the control terminal starts the servo motor 3. The servo motor 3 drives the rectangular plate 5 to rotate through the rotating shaft 4, thereby assisting in improving the cleaning effect of the cleaning liquid on the impurities in the mixing shell 2. After a period of time, the cleaning liquid is cleaned, and the control terminal turns off the servo motor 3 and opens the solenoid valve of the second discharge port 203. The impurities in the mixing shell 2 and the cleaning liquid above the interception net 6 are discharged from the second discharge port 203. Subsequently, the control terminal opens the solenoid valve in the first discharge port 202, and the remaining cleaning liquid in the mixing shell 2 is discharged from the first discharge port 202. The operator handles the cleaning liquid and impurities discharged from the mixing shell 2, and then resets the production device. The use of the production device is completed.

The upper part of the threaded rod 1002 is slidably connected with a spline rod 1004, and a first tension spring 1005 is fixed between the spline rod 1004 and the upper surface of the threaded rod 1002. The upper end of the spline rod 1004 is fixed with an insertion rod 1006, and the mixing shell 2 is provided with The limiting hole 204 cooperates with the insertion rod 1006, and the spline rod 1004 drives the insertion rod 1006 to move upward. When the insertion rod 1006 is inserted into the limiting hole 204, the insertion rod 1006 is limited by the limiting hole 204 and cannot rotate. The fixed sleeve 701 is connected to the cylindrical cavity 404, and the fixed sleeve 701 is slidably connected to the second push plate 1007 fixedly connected to the sliding rod 703. The first push plate 1003 moves downward, and the pressure in the cylindrical cavity 404 increases. The two second push plates 1007 move away from each other. A second tension spring 1008 is fixedly connected between the two second push plates 1007. The fixed tube 704 is provided with a limiting component, and the limiting component is used to limit the fixed tube 704.

[0046] like Fig. 9 and Fig.10 As shown, the limiting assembly includes a folding rod 1101, which is fixedly connected to an adjacent fixed tube 704, and the rotating shaft 4 is fixedly provided with two limiting plates 1102 symmetrically distributed on the left and right, and the symmetrically distributed limiting plates 1102 are slidably connected to a U-shaped rod 1103, and the middle part of the upper side of the U-shaped rod 1103 is rotatably connected to the spline rod 1004, and the U-shaped rod 1103 cooperates with the folding rod 1101, and the U-shaped rod 1103 moves upward to release the limiting of the two folding rods 1101, and the U-shaped rod 1103 is fixedly provided with a second L-shaped rod 1104 cooperating with the scraper ring 907, and when the scraper ring 907 contacts with the second L-shaped rod 1104, the scraper ring 907 drives the U-shaped rod 1103 to move upward through the second L-shaped rod 1104.

[0047] After adding the cleaning liquid into the mixing shell 2, since the impurities on the inner wall of the mixing shell 2 are thick, the impurities on the inner wall of the mixing shell 2 cannot be completely removed by relying solely on the flushing effect of the cleaning liquid. Therefore, it is necessary to scrape off the impurities on the inner wall of the mixing shell 2 layer by layer to increase the cleaning effect of the impurities on the inner wall of the mixing shell 2. The specific operation is as follows: the control terminal starts the electric push rod 801, and the telescopic end of the electric push rod 801 drives the U-shaped block 802 to move upward. The U-shaped block 802 drives the two scraping blocks 805 to move upward through the fixed ring 803 and the rotating ring 804. The scraping block 805 drives the telescopic rod 806 to slide upward along the guide groove 7051. The two scraping blocks 805 drive the scraper ring 907 to move upward through the connecting rod 908. At this time, the front part of the upper surface of the scraper ring 907 contacts the lower end of the second L-shaped rod 1104.

[0048] As the scraper ring 907 moves upward, the scraper ring 907 drives the second L-shaped rod 1104 to move upward, and the second L-shaped rod 1104 drives the U-shaped rod 1103 to move upward, and the U-shaped rod 1103 drives the spline rod 1004 to move upward, the first tension spring 1005 is stretched, and the spline rod 1004 drives the insertion rod 1006 to move upward. When the insertion rod 1006 is inserted into the limiting hole 204, the control terminal stops the electric push rod 801, and the insertion rod 1006 no longer moves upward. The insertion rod 1006 is limited by the limiting hole 204 and cannot rotate. The spline rod 1004 cannot rotate. The number of revolutions of the rotating shaft 4 each time is an integer to ensure that the insertion rod 1006 is inserted into the limiting hole 204. Then the control terminal starts the servo motor 3 to drive the rotating shaft 4 to rotate. The rotating shaft 4 drives the threaded sleeve 1001 to rotate through the support block. The threaded rod 1002 cannot rotate under the limit of the spline rod 1004. The threaded sleeve The rotation of 1001 drives the threaded rod 1002 to move downward, and the threaded rod 1002 drives the first push plate 1003 to move downward, the pressure in the cylindrical cavity 404 gradually increases, and the two second push plates 1007 move away from each other. Taking the second push plate 1007 on the right as an example, the second push plate 1007 drives the fixed tube 704 to move rightward through the sliding rod 703, and the fixed tube 704 drives the scraper 706 to move rightward through the rotating rod 705, and the distance between the scraper 706 and the inner wall of the mixing shell 2 is gradually shortened. With the rotation of the scraper 706, the scraper 706 scrapes off the impurities accumulated on the inner wall of the mixing shell 2 layer by layer, so as to facilitate the falling off of the thicker impurities accumulated in the mixing shell 2. In the process of the rotating rod 705 moving to the right, the rotating rod 705 moves to the right relative to the scraper block 805, and the telescopic rod 806 extends. The telescopic rod 806 is always limited and matched with the guide groove 7051 to prevent the rotating rod 705 from rotating.

[0049] The distribution of impurities on the inner wall of the mixing shell 2 is as follows: the impurity density on the side close to the inner wall of the mixing shell 2 is greater than the impurity density on the side away from the inner wall of the mixing shell 2. Therefore, in the process of the scraper 706 gradually approaching the inner wall of the mixing shell 2, it is necessary to reduce the moving speed of the scraper 706 close to the inner wall of the mixing shell 2 to ensure that the scraper 706 performs multiple scrapings when scraping the impurities on the side close to the inner wall of the mixing shell 2. The specific operation is as follows: in the process of the two second push plates 1007 moving away from each other, the tension of the second tension spring 1008 continues to increase. When the two second push plates 1007 move away from each other, the tension of the second tension spring 1008 continues to increase. Therefore, when the first push plate 1003 moves downward at a uniform speed, the speed at which the two second push plates 1007 move away from each other gradually decreases, and the impurities with high density on the inner wall of the mixing shell 2 are scraped multiple times to ensure that the impurities attached to the inner wall of the mixing shell 2 fall off.

[0050] When the scraper 706 rotates, the scraper 706 and the parts thereon will generate centrifugal force, resulting in the pressure in the cylindrical cavity 404 decreasing when the first push plate 1003 does not move downward, and the two second push plates 1007 move away from each other. In order to prevent the scraper 706 from contacting the inner wall of the mixing shell 2 in advance due to centrifugal force, resulting in prolonged wear of the scraper 706 or the inner wall of the mixing shell 2, it is necessary to limit the scraper 706 when the impurities on the inner wall of the mixing shell 2 are not cleaned, and when the U-shaped rod 1103 does not move upward, the U-shaped rod 1103 limits the two folding rods 1101, and the two folding rods 1101 cannot move away from each other, and at the same time, the two scrapers 706 cannot move away from each other, and when the insertion rod 1006 is inserted Before entering the limiting hole 204, the U-shaped rod 1103 moves upward to release the limiting of the two folding rods 1101. When the U-shaped rod 1103 moves upward, the limiting plate 1102 always limits the U-shaped rod 1103. When all the impurities in the mixing shell 2 are scraped off, the control terminal controls the output shaft of the servo motor 3 to rotate in the opposite direction, the threaded sleeve 1001 rotates in the opposite direction, the threaded rod 1002 drives the first push plate 1003 to move upward, the pressure in the cylindrical cavity 404 decreases, the two second push plates 1007 approach each other, the second tension spring 1008 resets, the two scrapers 706 gradually move away from the inner wall of the mixing shell 2, the telescopic rod 806 contracts, and the two folding rods 1101 approach each other.

[0051] When the folding rod 1101 returns to its initial position, the control terminal starts the electric push rod 801, the U-shaped block 802 moves downward, the scraper ring 907 moves downward to release the limit on the second L-shaped rod 1104, the first tension spring 1005 resets and drives the spline rod 1004 to move downward, the spline rod 1004 drives the insertion rod 1006 to move downward and move out of the limiting hole 204, the spline rod 1004 drives the U-shaped rod 1103 to move downward and limit the two folding rods 1101 again, the U-shaped rod 1103 drives the second L-shaped rod 1104 to move downward, and when the lower end of the second L-shaped rod 1104 contacts the scraper ring 907, the control terminal stops the electric push rod 801, and the second L-shaped rod 1104 no longer moves downward.

[0052] Example 3: Based on Example 2, a production method of dimethylthiotoluenediamine produced by a production device of dimethylthiotoluenediamine comprises the following steps:

[0053] S1: Add the raw material of dimethylthiotoluenediamine into the mixing shell 2, and the servo motor 3 drives the rotating shaft 4 and the rectangular plate 5 to rotate to stir and mix the materials in the shell 2;

[0054] S2: The scraper 706 rotates to scrape off the impurities adhering to the inner wall of the mixing shell 2, thereby reducing the amount of impurities accumulated on the inner wall of the mixing shell 2;

[0055] S3: The electric push rod 801 is started regularly, and the scraper block 805 moves downward to scrape off the impurities on the outside of the scraper plate 706, and the scraper ring 907 moves downward to scrape off the impurities on the rotating shaft 4 and the rectangular plate 5;

[0056] S4: After the material mixing is completed, the material and impurities in the mixing shell 2 are separated, the material is discharged first, and then a cleaning liquid is added to the mixing shell 2. The scraper 706 expands outward to scrape off the impurities on the inner wall of the mixing shell 2 layer by layer, and then the impurities are discharged.
