Description
Technical Field
[0001] The present invention relates to the technical field of vulcanizing agent processing, and more specifically, to a novel vulcanizing agent adding device. Background Art
[0002] Vulcanizing agents are substances that can cause polymers such as rubber to change from a linear structure to a network structure through cross-linking reactions, thereby improving many properties such as their physical and mechanical properties and chemical stability. Sulfur is the most traditional and widely used vulcanizing agent, with a relatively low price and wide sources. It is suitable for the vulcanization of a variety of general rubbers, such as natural rubber and styrene-butadiene rubber.
[0003] In the preparation process of vulcanizing agents, multiple processes such as melting, filtering, and buffering are involved. Among them, when making sulfur into a vulcanizing agent, a key step is to pour sulfur into a heating reaction kettle and carry out melting and mixing operations with other related materials.
[0004] After sulfur gradually melts and turns into a liquid state in the heating reaction kettle, there is inevitably air in the reaction kettle. This air will come into contact with the liquid sulfur. During this process, some sulfur components in the sulfur will undergo oxidation reactions with the oxygen in the air, resulting in a reduction in the effective sulfur components originally contained in the sulfur. The reduction of sulfur components will affect the performance of the subsequent vulcanizing agent, greatly reducing the role it plays in actual applications. Therefore, in order to ensure the quality and vulcanization effect of the vulcanizing agent, a novel vulcanizing agent adding device is needed to effectively solve a series of problems caused by sulfur oxidation. Summary of the Invention
[0005] The purpose of the present invention is to provide a novel vulcanizing agent adding device to solve the problems raised in the above background art.
[0006] To achieve the above purpose, the present invention provides a novel vulcanizing agent adding device, including the inner barrel of a reaction kettle. A heating assembly is arranged outside the inner barrel for heating the inside of the inner barrel. A barrel cover is fixedly installed at the top of the inner barrel. A plurality of feeding ports are opened at the top of the barrel cover. A support plate is arranged above the barrel cover. A driving motor is installed at the top of the support plate. The output shaft of the driving motor penetrates the support plate and is provided with a rotating rod. The bottom end of the rotating rod penetrates the barrel cover and extends into the inner barrel. Stirring paddles are rotatably installed on the outer surface of the rotating rod. The heating component includes an outer barrel and a heating barrel. The heating barrel is hermetically sleeved outside the inner barrel, and the outer barrel is sleeved outside the heating barrel for heat insulation of the heating barrel. An installation groove is formed at the bottom of the outer barrel, the top of the installation groove penetrates through the outer barrel and extends into the interior of the heating barrel. An installation box is fixedly installed inside the installation groove, and a heating rod is arranged inside the installation box. A liquid injection pipe and a gas outlet pipe that penetrate into the heating barrel are installed on the outer surface of the outer barrel. A discharge port one that penetrates into the interior of the inner barrel is installed at the bottom of the outer barrel. A filtering component is arranged at the bottom of the discharge port one for filtering the heated and melted material. A gas injection pipe and an exhaust component that penetrate through the outer barrel and the heating barrel and extend into the inner barrel are installed on the outer surface of the outer barrel. The gas injection pipe is used to inject inert gas into the interior of the inner barrel, and the exhaust component is used to discharge the gas inside the inner barrel.
[0007] As a further improvement of this technical solution, the filtering component includes a filtering box. Two filter meshes distributed vertically are installed inside the filtering box. A feed inlet is formed at the top of the filtering box, and the feed inlet is fixedly installed at the bottom of the discharge port one. A discharge port two is formed at the bottom of the filtering box, and a discharge pipe is installed at the bottom of the discharge port two. An air injection sleeve is sleeved on the outer surface of the discharge pipe.
[0008] As a further improvement of this technical solution, the exhaust component includes an exhaust pipe. One end of the exhaust pipe penetrates through the outer barrel and the heating barrel and extends into the interior of the inner barrel. The other end of the exhaust pipe is installed on the outer surface of the gas outlet pipe and is communicated with the gas outlet pipe. The other end of the gas outlet pipe is fixedly installed with a delivery pipe, and the other end of the delivery pipe is installed on the outer surface of the air injection sleeve for injecting hot air flow into the interior of the air injection sleeve.
[0009] As a further improvement of this technical solution, an air outlet is formed on the outer surface of the air injection sleeve for discharging the gas inside the air injection sleeve.
[0010] As a further improvement of this technical solution, a support rod is fixedly installed at the bottom of the support plate. There are four support rods, and the four support rods are used to support and fix the support plate.
[0011] As a further improvement of this technical solution, there are two heating rods. The two heating rods are located inside the heating barrel and are used to heat the liquid inside the heating barrel.
[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. In this new vulcanizing agent adding device, by setting an inner barrel, a heating barrel and an outer barrel, the heating rod can heat the oil in the heating barrel, so that the oil heats the inner barrel, and the sulfur and related materials injected into the inner barrel can be melted and mixed. When the sulfur melts, inert gas can be injected into the inner barrel through an injection pipe. The inert gas squeezes out the air inside the inner barrel, avoiding oxidation with air when the sulfur melts and reducing the sulfur content, thus increasing the vulcanization effect of the generated vulcanizing agent.
[0013] 2. In this new vulcanizing agent adding device, after the sulfur and related materials are melted and mixed, the solution can flow into the filter box through the bottom discharge port 1. The solid impurities in the solution can be filtered through two layers of filter meshes, avoiding impurities mixing inside the solution and affecting the use effect of the generated vulcanizing agent.
[0014] 3. In this new vulcanizing agent adding device, after the solution is filtered, the solution flows into the discharge pipe through the discharge port 2 at the bottom of the filter box. Since the solution needs to flow down slowly during filtration, it may solidify in the discharge pipe. By connecting the exhaust pipe extending into the inner barrel with the air outlet pipe extending into the heating barrel, and then transporting the hot air flows discharged from the exhaust pipe and the air outlet pipe to the injection sleeve on the outer surface of the discharge pipe through a delivery pipe, the solution can be transported with heat preservation, avoiding the situation of solidification and blockage of the solution.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0018] Embodiment Please refer to Figures 1 - 3 As shown in the figure, the purpose of this embodiment is to provide a new type of vulcanizing agent adding device, which includes the inner barrel 1 of the reaction kettle. A heating component 2 is arranged outside the inner barrel 1 for heating the inside of the inner barrel 1. A barrel cover 11 is fixedly installed at the top of the inner barrel 1. A plurality of feeding ports 12 are opened at the top of the barrel cover 11. A support plate 13 is arranged above the barrel cover 11. A driving motor 14 is installed at the top of the support plate 13. The output shaft of the driving motor 14 penetrates through the support plate 13 and is installed with a rotating rod 15. The bottom end of the rotating rod 15 penetrates through the barrel cover 11 and extends into the inner barrel 1. A stirring paddle 16 is rotatably installed on the outer surface of the rotating rod 15; The heating component 2 includes an outer barrel 21 and a heating barrel 22. The heating barrel 22 is hermetically sleeved outside the inner barrel 1. The outer barrel 21 is sleeved outside the heating barrel 22 for heat insulation of the heating barrel 22. An installation groove is opened at the bottom of the outer barrel 21. The top of the installation groove penetrates through the outer barrel 21 and extends into the heating barrel 22. An installation box 23 is fixedly installed inside the installation groove. A heating rod 24 is arranged inside the installation box 23. A liquid injection pipe 25 and an air outlet pipe 26 that penetrate into the heating barrel 22 are installed on the outer surface of the outer barrel 21. A first discharge port 27 that penetrates into the inner barrel 1 is installed at the bottom of the outer barrel 21. A filtering component 3 is arranged at the bottom of the first discharge port 27 for filtering the heated and melted materials; Four support rods 7 are fixedly installed at the bottom of the support plate 13, and the four support rods 7 are used for supporting and fixing the support plate 13; Furthermore, by providing the inner barrel 1, the heating barrel 22 and the outer barrel 21, the heating rod 24 can be installed in the installation box 23. The heating barrel 22 can be filled with oil through the liquid injection pipe 25, enabling the heating rod 24 to heat the oil. The sulfur and related materials poured into the inner barrel 1 through the charging port 12 can be stirred and mixed by driving the rotating rod 15 and the stirring paddle 16 with the driving motor 14, allowing the oil to heat the inner barrel 1 and maintaining the temperature inside the inner barrel 1 to melt and mix the sulfur and the materials; the melted sulfur solution can be injected into the interior of the filtering assembly 3 through the first discharge port 27 to filter out the solid particles and impurities that cannot be melted in the solution.
[0019] An air injection pipe 4 and an exhaust assembly 41 that penetrate the outer barrel 21 and the heating barrel 22 and extend to the inner barrel 1 are installed on the outer surface of the outer barrel 21. The air injection pipe 4 is used to inject inert gas into the interior of the inner barrel 1, and the exhaust assembly 41 is used to discharge the gas inside the inner barrel 1.
[0020] Furthermore, when the sulfur and the materials in the inner barrel 1 melt, inert gas is injected into the inner barrel 1 through the air injection pipe 4, and the air inside the inner barrel 1 is discharged from the exhaust assembly 41, preventing the melted sulfur solution from oxidizing with the air and causing a reduction in the sulfur content.
[0021] It should be noted that inert gases such as nitrogen and argon have very stable chemical properties and hardly react with other substances under normal conditions.
[0022] First, considering the problem of how to filter the impurities in the sulfur solution, present Figure 3 And Figure 4 , the specific structure of the filtering assembly 3 is disclosed. The filtering assembly 3 includes a filtering box 301. Two filter meshes 302 distributed vertically are installed inside the filtering box 301. A feed inlet is provided at the top of the filtering box 301, and the feed inlet is fixedly installed at the bottom of the first discharge port 27. A second discharge port 303 is provided at the bottom of the filtering box 301. A discharge pipe 304 is installed at the bottom of the second discharge port 303, and an air injection sleeve 305 is sleeved on the outer surface of the discharge pipe 304.
[0023] Furthermore, through the first discharge port 27 that penetrates into the inner barrel 1, a spherical valve is installed inside the first discharge port 27 to close the discharge port. The first discharge port 27 is butt - connected to the top of the filtering box 301. After the sulfur solution is completely melted and mixed, the spherical valve is opened, and inert gas is continuously injected into the inner barrel 1, enabling the solution to enter the interior of the filtering box 301. After passing through the two - layer filter meshes 302 inside the filtering box 301, the impurities in the solution can be filtered. The filtered solution can flow out from the second discharge port 303 at the bottom of the filtering box 301 into the discharge pipe 304 and be injected into a buffer device for shaping and maintaining or injected into a reaction device for catalysis.
[0024] Secondly, considering that the solution will solidify due to heat reduction after passing through the discharge pipe 304 of the filter cartridge 301, show Figure 5 and Figure 6 , the specific structure of the exhaust assembly 41 is disclosed. The exhaust assembly 41 includes an exhaust pipe 401. One end of the exhaust pipe 401 penetrates through the outer barrel 21 and the heating barrel 22 and extends into the interior of the inner barrel 1. The other end of the exhaust pipe 401 is installed on the outer surface of the air outlet pipe 26 and is communicated with the air outlet pipe 26. A delivery pipe 5 is fixedly installed at the other end of the air outlet pipe 26. The other end of the delivery pipe 5 is installed on the outer surface of the air injection sleeve 305 for injecting hot air flow into the interior of the air injection sleeve 305.
[0025] An air outlet 6 is formed on the outer surface of the air injection sleeve 305 for discharging the gas inside the air injection sleeve 305.
[0026] Furthermore, by installing the air outlet pipe 26 inside the heating barrel 22, the hot air generated by heating the oil liquid in the heating barrel 22 can be discharged through the air outlet pipe 26. And an exhaust pipe 401 communicated with the outer surface of the air outlet pipe 26 is installed inside the inner barrel 1. The exhaust pipe 401 can discharge the air and inert gas inside the inner barrel 1. Since the air and inert gas inside the inner barrel 1 will also be heated and raised in temperature, the hot air flow is injected into the air injection sleeve 305 through the delivery pipe 5 connected to the air outlet pipe 26. Injecting the hot air flow into the air injection sleeve 305 on the outer surface of the discharge pipe 304 can enable the hot air flow to circulate inside the air injection sleeve 305, perform heat preservation transportation on the solution conveyed in the discharge pipe 304, and avoid the situation of solution solidification.
[0027] Finally, considering the problem of how to heat the inner barrel 1, show Figure 5 and Figure 7 , there are two heating rods 24. The two heating rods 24 are located inside the heating barrel 22 to heat the liquid inside the heating barrel 22.
[0028] Furthermore, by hermetically inserting one end of the heating rod 24 into the interior of the installation box 23, the oil liquid filled into the heating barrel 22 through the liquid injection pipe 25 can come into contact with the heating rod 24, energize the heating rod 24, heat the oil liquid, and the heated oil liquid will heat the inner barrel 1 and heat and melt the materials inside the inner barrel 1.
[0029] In summary, the working principle of this solution is as follows: By setting the inner barrel 1, the heating barrel 22 and the outer barrel 21, the heating rod 24 can heat the oil in the heating barrel 22, so that the oil heats the inner barrel 1, and the sulfur and related materials injected into the inner barrel 1 can be melted and mixed. When the sulfur melts, inert gas can be injected into the inner barrel 1 through the injection pipe 4. The inert gas squeezes out the air inside the inner barrel 1, avoiding oxidation with air when sulfur melts, which may cause a reduction in sulfur content and increasing the vulcanization effect of the generated vulcanizing agent.
[0030] After the sulfur and related materials are melted and mixed, the solution can flow into the filter box 301 through the bottom discharge port 1 27. The solid impurities in the solution can be filtered through two layers of filter screens 302, avoiding impurities being doped inside the solution and affecting the use effect of the generated vulcanizing agent.
[0031] After the solution is filtered, the solution flows into the discharge pipe 304 through the discharge port 2 303 at the bottom of the filter box 301. Since the solution needs to flow down slowly during filtration, it may cause the solution to solidify in the discharge pipe 304. By connecting the exhaust pipe 401 extending into the inner barrel 1 with the air outlet pipe 26 extending into the heating barrel 22, and then transporting the hot air flow discharged from the exhaust pipe 401 and the air outlet pipe 26 to the air injection sleeve 305 on the outer surface of the discharge pipe 304 through the delivery pipe 5, the solution can be transported while being kept warm, avoiding the situation of solidification and blockage of the solution.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
