Description

Technical Field

[0001] The invention relates to the technical field of rubber band production, in particular to a raw material vulcanization device for rubber band production. Background Art

[0002] In the production process of rubber bands, chemicals such as sulfur need to be incorporated into the rubber band raw materials to make them more elastic. For example, Chinese patent No. CN116214790A discloses a vulcanization device for rubber band production. The vulcanization operation of the rubber raw materials is realized through the cooperation of components such as a dosing chamber and a dosing cylinder. By rotating the stirring blades installed in the dosing chamber, the rubber blocks can be broken into small pieces during the vulcanization process, so that the mixing with the chemicals is more uniform, which solves the problem of uneven mixing inside and outside the rubber blocks in the traditional vulcanization process, thereby improving the vulcanization effect of the rubber raw materials.

[0003] During the vulcanization process of rubber raw materials, the vulcanization temperature, pressure and vulcanization time need to be strictly controlled, otherwise under-vulcanization or over-vulcanization may occur, which will affect the quality of the rubber finished product. Especially during the vulcanization process, the interior of the tank is under high temperature and high pressure, and it is necessary to pay attention to the pressure inside the tank in real time to avoid excessive pressure and cause the tank to rupture. In addition, a certain amount of toxic gas will be generated during the vulcanization process, which will be inhaled by the human body and affect health. However, in the process of vulcanizing the rubber raw materials, the vulcanization device in the above application is not sufficient to fully and evenly vulcanize the rubber raw materials by simply stirring, and the whole is not sealed enough. During the vulcanization process, harmful gases will diffuse in the processing site, affecting the health of the workers. Therefore, there are certain limitations. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1

[0029] Based on the existing problems that the internal pressure of the vulcanization tank 1 needs to be observed in real time to avoid the tank body from rupturing due to excessive pressure, increasing labor costs, and the harmful gases generated during the vulcanization process spreading in the processing site and affecting the health of workers, this embodiment provides a raw material vulcanization device for rubber band production, please refer to Figure 1-Figure 6 The embodiment provides a raw material vulcanization device for rubber band production, which can improve the automation degree of vulcanization and the safety of vulcanization processing. The raw material vulcanization device for rubber band production includes a sealed tank door 2 installed at one end of a vulcanization tank 1, an automatic pressure relief mechanism 3 for adaptively adjusting the internal pressure of the vulcanization tank 1 is installed on one side of the vulcanization tank 1, and an exhaust gas purification mechanism 4 for purifying toxic gases generated during the vulcanization process is installed on the top of the vulcanization tank 1. When the rubber raw material inside the vulcanization tank 1 is vulcanized, when the internal pressure is too high, the pressure inside the vulcanization tank 1 is adaptively adjusted by the automatic pressure relief mechanism 3 to avoid damage to the vulcanization tank 1 caused by excessive pressure, and after the vulcanization is completed, the harmful gases generated during the vulcanization process are extracted and purified by the exhaust gas purification mechanism 4 to avoid the harmful gases from spreading in the processing site and affecting the health of the workers.

[0030] Since the existing technology needs to observe the internal pressure of the vulcanization tank 1 in real time to avoid the tank body from rupturing due to excessive pressure, which increases the labor cost, an automatic pressure relief mechanism 3 is proposed, which can automatically adjust the internal pressure of the tank body when the internal pressure of the vulcanization tank 1 is too high. The automatic pressure relief mechanism 3 includes a pressure relief pipe 301 installed on one side of the vulcanization tank 1, a liquid storage tank 302 is installed on one side of the vulcanization tank 1, and pure water is perfused inside the liquid storage tank 302. The pressure relief pipe 301 extends into the water body in the liquid storage tank 302, and a spring 303 is installed on the bottom wall of the pressure relief pipe 301. A sealing piston 304 slidably connected to the inner wall of the pressure relief pipe 301 is installed on the top of the spring 303. The pressure relief pipe 301 A pressure relief hole 305 is provided below the outer surface of the autoclave 1, and the sealing piston 304 is made of rubber material. The pressure relief hole 305 is located below the sealing piston 304 under normal conditions. When the pressure inside the autoclave 1 is too high, the high-pressure gas rushes into the interior of the pressure relief pipe 301 and pushes the sealing piston 304 to move downward to squeeze the spring 303 until the sealing piston 304 moves to below the pressure relief hole 305 provided on the pressure relief pipe 301. At this time, the high-pressure gas is discharged into the water body inside the liquid storage tank 302 through the pressure relief hole 305, thereby completing automatic pressure relief. After the pressure relief is completed, the spring 303 pushes the sealing piston 304 to reset under its own elasticity, so that the autoclave 1 remains airtight.

[0031] Since an observation window 306 is installed on the front of the liquid storage tank 302, a water injection pipe 307 and a sewage pipe 308 are respectively installed on the top and bottom of the right side of the liquid storage tank 302, and an electric valve 309 is installed on both. During the pressure relief process, the harmful gas inside the vulcanizer 1 is discharged into the water body in the liquid storage tank 302, the turbidity of the water body is observed through the observation window 306, the electric valve 309 is started regularly, the sewage is discharged through the sewage pipe 308, and crystal water is injected through the water injection pipe 307.

[0032] Harmful gases will be generated during the vulcanization process of rubber raw materials. If they are not purified and diffused in the processing site, they will affect the health of workers. Therefore, the device is also provided with an exhaust gas purification mechanism 4, which includes a water washing box 401 installed on the top of the vulcanization tank 1, which is filled with pure water. An air pump 402 is installed on the left side of the water washing box 401, and an exhaust pipe 403 is installed at the air suction port of the air pump 402, and the other end of the exhaust pipe 403 extends into the interior of the vulcanization tank 1. A connecting pipe 404 is installed at the exhaust port of the air pump 402, and the other end of the exhaust pipe 404 extends into the water body in the water washing box 401. An adsorption component 405 for adsorbing and removing odors from the waste gas after water washing and purification is installed on the right side of the water washing box 401. After vulcanization is completed, the air pump 402 is started to extract the harmful gases in the vulcanization tank 1 through the exhaust pipe 403, and discharge them into the interior of the water washing box 401 through the connecting pipe 404, and the particulate impurities in the harmful gases and some toxic substances soluble in water are washed and purified.

[0033] Due to the use of different vulcanizing agents, the harmful gas components generated in the vulcanization process are different. Simply relying on water washing and purification is not enough to completely eliminate the hidden dangers. Therefore, the device is also provided with an adsorption component 405, which includes an adsorption tower 4051 installed on the right side of the water washing box 401, two activated carbon plates 4052 are installed in the middle of the interior of the adsorption tower 4051, and a gas pipeline 4053 is installed on the top of the water washing box 401, and the other end thereof extends into the interior of the adsorption tower 4051. A discharge pipe 4054 is installed on the top of the adsorption tower 4051, and a desorption component 406 for high-temperature desorption of the activated carbon plate 4052 after adsorption saturation is installed on the rear side of the adsorption tower 4051. The gas after water washing and purification is discharged into the interior of the adsorption tower 4051 through the gas pipeline 4053, and passes through the activated carbon plate 4052 when drifting upward, and the residual harmful substances therein are adsorbed and purified by the activated carbon plate 4052, thereby improving the purification effect and better protecting the health of the workers.

[0034] Since the activated carbon plate 4052 has an adsorption saturation value, it needs to be replaced frequently, which not only increases the production cost but also makes the operation more complicated. Therefore, the device is also provided with a desorption component 406 for high-temperature desorption of the activated carbon plate 4052. The desorption component 406 includes an electric heating tube 4061 installed between the two activated carbon plates 4052, an air pump 4062 connected to the rear side of the adsorption tower 4051, an air suction port connected to the air pump 4062 is installed with an air suction pipe 4063, and the top of the air suction pipe 4063 extends into the interior of the adsorption tower 4051 and is located above the activated carbon plate 4052, and the air outlet connected to the air pump 4062 is installed with a rewashing pipe 4064, and the other end of the rewashing pipe 4064 extends into the water outlet. Inside the water body in the washing box 401, a separation component 407 for gas-liquid separation of the exhaust gas is installed above the inside of the washing box 401. When the activated carbon plate 4052 is saturated with adsorption, the electric heating tube 4061 is started to desorb the two activated carbon plates 4052 at high temperature, thereby realizing the reuse of the activated carbon plates 4052. There is no need to frequently replace the activated carbon plates 4052, and regular replacement is sufficient. At the same time, the connected air pump 4062 is started to pump the gas generated during the desorption process into the inside of the re-washing pipe 4064 through the exhaust pipe 4063, and finally discharged into the washing box 401 for re-washing and purification, so as to avoid the overflow of harmful gases generated during desorption and affect the health of the workers.

[0035] A temperature and pressure gauge 5 is installed on the top of the vulcanization tank 1, and bases 6 are installed on both sides of the bottom of the vulcanization tank 1. The temperature and pressure gauge 5 displays the temperature and pressure inside the vulcanization tank 1 in real time, which is convenient for workers to control the vulcanization process.

[0036] Example 2

[0037] On the basis of Example 1, Figure 1-Figure 6As shown, since the harmful gas is purified by water washing, the discharged gas contains a certain amount of moisture, including a certain amount of water vapor generated when the activated carbon plate 4052 is subjected to high-temperature desorption, and the direct discharge of water vapor will cause the construction environment to be too humid. Therefore, the device is also provided with a separation component 407, and the separation component 407 includes a cyclone plate 4071 installed above the inside of the adsorption tower 4051, and the inner wall of the adsorption tower 4051 is installed with a guide plate 4072, and it is located on the cyclone plate 4071. Below, a water outlet pipe 4073 is installed on the right side of the adsorption tower 4051, and an electric valve 309 is also installed on it. Water vapor passes through the swirl plate 4071, and under the guidance of the blades of the swirl plate 4071, the gas generates a rotational motion when passing through the swirl plate 4071. The centrifugal force generated causes the liquid droplets in the gas to be thrown to the inner wall of the adsorption tower 4051, and under the action of gravity, they flow down along the wall into the interior of the guide plate 4072, and are finally discharged through the water outlet pipe 4073, thereby realizing gas-liquid separation.
