Abstract
Description
Technical Field
[0001] The invention relates to the technical field of sulfur dissolving equipment, in particular to sulfur dissolving equipment for producing rubber additives and a sulfur dissolving process thereof. Background Art
[0002] Rubber additives refer to the general term for fine chemical products added during the processing of natural rubber or synthetic rubber into rubber products to give rubber products performance, extend their service life and improve the processing performance of rubber compounds.
[0003] In the prior art, during the production of rubber additives, sulfur, aniline and other raw materials need to be heated and melted in a sulfur dissolving tank. When the mixture in the sulfur dissolving tank is discharged, impurities in the mixture need to be filtered out through a filter. The high surface tension of sulfur during filtration slows the filtration speed. When the mixture is discharged from the discharge pipe, the discharge pipe cannot be filled, resulting in low discharge efficiency and difficulty in controlling the discharge volume of the mixture. Moreover, in the process of heating sulfur, it is usually heated at the bottom of the sulfur dissolving tank to facilitate stirring of the raw materials, and the sulfur is discharged and filtered after it is completely melted. However, the sulfur close to the heating area heats up and melts faster and can quickly enter a molten state, while the sulfur far away from the heating area heats up slower, which can easily lead to uneven heating, and the viscosity of the melted sulfur will change with the change of temperature. When the temperature is low, the viscosity of the sulfur is high and difficult to filter. When the temperature is high, the viscosity of the sulfur is still large and toxic hydrogen sulfide gas will be generated. Therefore, the melted sulfur needs to be controlled within a certain temperature range so that the sulfur is at the optimal viscosity and then discharged. The existing method of centralized melting and unified discharge will cause the sulfur that has met the standards to continue to be heated, which can easily lead to the generation of toxic gases. The generated toxic gases cannot be detected and treated in time and can easily cause harm to the staff. Summary of the Invention

DETAILED DESCRIPTION
[0017] See also Figures 1-11 The present invention provides a technical solution: a sulfur dissolving device for producing rubber additives, comprising a tank body 1, a sealing cover 2, a adding cover 3, a driving motor 4, a rotating shaft 5 and a stirring rod 6; A heating ring 7 and a filter plate 8 are fixedly connected inside the tank body 1. The filter plate 8 is located below the heating ring 7. Two semicircular heating plates 9 are elastically and slidably connected to the bottom of the heating ring 7. The two heating plates 9 are combined to block the middle position of the heating ring 7. An annular groove 10 is provided inside the tank body 1. An annular floating block 11 is provided in the groove 10. The bottom of the floating block 11 is connected to two pull ropes 12 that pass through the groove 10 and are respectively connected to the sides of the two heating plates 9. The pull rope 12 is used to pull the heating plate 9 to move when the floating block 11 moves upward. The bottom of the tank body 1 corresponding to the bottom of the filter plate 8 is conical, and the bottom of the tank body 1 is connected to a discharge pipe 13; In the production process of rubber additives, it is necessary to first put raw materials such as sulfur and aniline into the tank body 1 and seal the tank body 1 with a sealing cover 2. Then the heating ring 7 and the heating plate 9 heat the raw materials in the tank body 1. At the same time, the driving motor 4 drives the rotating shaft 5 and the stirring rod 6 to rotate synchronously. The stirring rod 6 can stir and mix the raw materials inside the tank body 1. When the temperature of the raw materials inside the tank body 1 rises to a certain level, the raw materials gradually melt into liquid. The viscosity of the raw materials will decrease with the increase of temperature within a certain range. When the viscosity of the melted raw materials decreases to a certain level, the floating block 11 moves upward under the buoyancy of the melted raw materials. The floating block 11 pulls the two heating plates 9 to both sides by pulling the rope 12. The middle position of the heating ring 7 is opened, and the melted raw materials pass through the heating plate 9. The ring 7 flows to the surface of the filter plate 8 for filtration, and the filtered raw materials flow to the conical bottom position of the tank body 1 and gather and then are discharged through the discharge pipe 13. The present application uses the floating block 11 to pull the heating plate 9, which can discharge the melted raw materials when the viscosity is reduced to a certain level, so that the raw materials are discharged immediately after being heated and melted to the optimal viscosity, without overheating the raw materials and avoiding the generation of hydrogen sulfide gas. The filter plate 8 is located below the heating ring 7 and the heating plate 9 and will not affect the normal heating and mixing of the raw materials. The filtered raw materials gather at the conical bottom position of the tank body 1 to the discharge pipe 13, so that the discharge pipe 13 can be filled with raw materials when discharging the melted raw materials, thereby improving the discharge efficiency and being able to control the discharge amount as needed.
[0018] During the production of rubber additives, the surface of the filter plate 8 is easily clogged with impurities. As a further solution of the present invention, the rotating shaft 5 passes through the heating plate 9 and extends to the surface of the filter plate 8. A cleaning plate 14 located on the surface of the filter plate 8 is fixedly connected to the surface of the rotating shaft 5. The cleaning plate 14 rotates to clean the impurities and the like accumulated on the surface of the filter plate 8. During the production of rubber additives, when the driving motor 4 drives the rotating shaft 5 and the stirring rod 6 to rotate, the rotating shaft 5 drives the cleaning plate 14 to rotate synchronously. The rotation of the cleaning plate 14 can scrape and clean the impurities accumulated on the surface of the filter plate 8, and the cleaning plate 14 can push the melted raw materials during the movement to increase the filtration rate.
[0019] In the process of producing rubber additives, when there are too many impurities on the surface of the filter plate 8, the impurities scraped by the cleaning plate 14 cannot be discharged, which still affects the filtering effect of the filter plate 8. As a further solution of the present invention, the surface of the tank body 1 is connected with a recovery pipe 16 through the recovery port 15. The recovery port 15 is located at the surface of the filter plate 8. The recovery pipe 16 is connected with the external storage tank. The inner wall of the tank body 1 is provided with a slide groove 17 corresponding to the position of the recovery port 15. A sliding plate 18 is elastically slidably connected in the slide groove 17. An opening 19 is provided on the surface of the sliding plate 18. The opening 19 is staggered with the recovery port 15. A toggle block 20 is elastically slidably connected to the surface of the sliding plate 18. The upper end of the toggle block 20 is in contact with the inner wall of the slide groove 17. When the cleaning plate 14 moves to the position of the toggle block 20, the sliding plate 18 can be driven to move by the toggle block 20. A give way groove 21 is provided on the upper side of the slide groove 17. In the process of producing rubber additives, when the rotating shaft 5 drives the cleaning plate 14 to rotate, the cleaning plate 14 can scrape and push the impurities attached to the surface of the filter plate 8. The impurities attached to one side of the cleaning plate 14 are moved toward the edge of the filter plate 8 by the centrifugal force as it rotates. When the cleaning plate 14 moves to the position of the toggle block 20, the cleaning plate 14 pushes the sliding plate 18 to move together through the toggle block 20. Then, when the opening 19 is connected to the recovery port 15 and the recovery pipe 16, the impurities accumulated on the surface of the cleaning plate 14 can be removed by the cleaning plate 14 from the filter plate 8. During the cleaning process, it flows through the recovery pipe 16 to the external storage tank for recovery, which is conducive to discharging impurities accumulated on the surface of the cleaning plate 14, ensuring the filtering effect of the filter plate 8, and avoiding the impurities cleaned by the cleaning plate 14 from being retained, and the impurities continue to accumulate and clog the filter plate 8. Subsequently, when the toggle block 20 moves to the position of the give way groove 21, the toggle block 20 moves into the give way groove 21 and passes over the cleaning plate 14. The sliding plate 18 returns to its original position under the action of the spring force, and the opening 19 and the recovery port 15 are re-staggered and sealed to prevent the raw materials in the tank body 1 from leaking.
[0020] In the process of producing rubber additives, when the melted raw materials are discharged, the heating plate 9 is turned on, and the heating rate of the middle position of the heating ring 7 is reduced. The raw materials that have not reached the temperature in the middle position of the tank body 1 are easily moved to the filter plate 8 position along with other melted raw materials. As a further solution of the present invention, the surface of the rotating shaft 5 is elastically rotatably connected to a toggle plate 22 in a horizontal state, and a top block 23 is fixedly connected to the bottom of the toggle plate 22. A plurality of push rods 24 are slidably connected in the groove 10. The end of the push rod 24 extends to the outside of the groove 10 and is fixedly connected to a push ring 25. The push ring 25 is located below the top block 23. When the floating block 11 moves upward, it can squeeze the push rod 24 to move upward; During the production of rubber additives, the rotating shaft 5 drives the stirring rod 6 and the toggle plate 22 to rotate to stir the raw materials. The toggle plate 22 is initially horizontal and will not affect normal stirring. Subsequently, when the floating block 11 moves upward, the floating block 11 squeezes the push rod 24 and the push ring 25 to move upward. The push ring 25 pushes the toggle plate 22 to flip a certain angle through the top block 23, so that the toggle plate 22 can push the raw materials to the surroundings during subsequent rotation, so that the raw materials move toward the position of the heating ring 7, ensuring that the raw materials can be fully heated when moving toward the inside of the heating ring 7.
[0021] During the production of rubber additives, when a large amount of impurities accumulate on the surface of the cleaning plate 14, the impurities easily pass over the cleaning plate 14. As a further solution of the present invention, an arc-shaped gathering groove 26 is formed on the surface of the cleaning plate 14. The gathering groove 26 is used to gather the impurities cleaned by the cleaning plate 14 so that the impurities can be discharged through the recovery port 15. During the production of rubber additives, when the cleaning plate 14 cleans the surface of the filter plate 8, the cleaned impurities can be gathered in the gathering groove 26 on the surface of the cleaning plate 14, ensuring that the cleaned impurities can be gathered for subsequent discharge, and avoiding the cleaned impurities from crossing the cleaning plate 14 and clogging the filter plate 8 again, affecting the filtering effect of the filter plate 8. Subsequently, when the impurities are discharged, the end of the gathering groove 26 passes through the cleaning plate 14, and the impurities in the gathering groove 26 can be directly moved from the end of the cleaning plate 14 through the opening 19 and the recovery port 15 to the recovery pipe 16.
[0022] During the production of rubber additives, when the cleaning plate 14 moves, the raw materials flowing outside the cleaning plate 14 are likely to carry away impurities in the collecting tank 26. As a further embodiment of the present invention, a plurality of through holes 27 are formed on the surface of the cleaning plate 14. The through holes 27 are used to allow the molten sulfur to pass through when the cleaning plate 14 moves. During the production of rubber additives, when the cleaning plate 14 moves to clean the surface of the filter plate 8, the melted raw material can pass through the through hole 27, and the impurities are blocked in the gathering tank 26, preventing the impurities in the gathering tank 26 from being carried to the outside during the flow of external liquid, reducing the subsequent impurity discharge efficiency and reducing the filtering effect of the filter plate 8.
[0023] During the production of rubber additives, melted raw materials are easily accumulated at the bottom of the groove 10. As a further solution of the present invention, a plurality of communication ports 28 are opened at the bottom of the groove 10, and the bottom of the communication ports 28 is located below the heating ring 7; During the production of rubber additives, after the floating block 11 moves upward, the raw materials at the bottom of the groove 10 can flow to the surface of the filter plate 8 through the connecting port 28, avoiding the accumulation of melted raw materials at the bottom of the groove 10 and the inability to filter and discharge them in time, resulting in excessive heating and generation of toxic gases, which affects the health of workers.
[0024] In the process of producing rubber additives, the ends of the two heating plates 9 cannot be well merged. As a further solution of the present invention, the sides of the two heating plates 9 that are close to each other are provided with stepped inclined surfaces. During the production of rubber additives, the two heating plates 9 can be well combined through the stepped slopes at the ends, ensuring the blocking and sealing of the heating ring 7, so that the raw materials can be fully heated.
[0025] A sulfur dissolving process for producing rubber additives, the specific steps of the process are as follows: Step 1: First, put the raw materials such as sulfur and aniline into the tank body 1 and seal the tank body 1 with the sealing cover 2; Step 2: The heating ring 7 and the heating plate 9 then heat the sulfur and aniline. During the heating, the stirring rod 6 stirs the sulfur and aniline. Step 3: When the sulfur is melted and mixed with aniline, and the viscosity of the mixture decreases when the temperature reaches a certain range, the floating block 11 moves upward due to the buoyancy of the melted sulfur; Step 4: The floating block 11 moves upwards and can pull the heating plate 9 apart by pulling the rope 12, and the middle part of the heating ring 7 opens; Step 5: The mixture can flow through the heating ring 7 to the surface of the filter plate 8 for filtration; Step 6: The filtered mixture moves to the conical bottom of the tank body 1 to be gathered, and the gathered mixture can be discharged from the tank body 1 through the discharge pipe 13 .
