Description

Technical Field

[0001] This utility model belongs to the field of rubber manufacturing technology, specifically a steam-heated vulcanizing tank for rubber manufacturing. Background Technology

[0002] After vulcanization, rubber becomes non-sticky and less prone to breakage. Most rubber products are made from this type of rubber, also known as cured rubber, commonly called rubber or rubber sheet. Direct steam vulcanization refers to the process of introducing steam into a vulcanizing tank to vulcanize the rubber products inside. For example, large vertical vulcanizing tanks for vulcanizing tires and horizontal long vulcanizing tanks for vulcanizing rubber hoses both involve directly introducing steam into the tank. The advantages of direct steam vulcanization are high thermal efficiency, easy control of vulcanization temperature, uniform temperature distribution, and high production efficiency.

[0003] However, the steam supply of existing steam-heated vulcanizing tanks used in rubber manufacturing requires manual control. When there is no supervision, it is difficult to ensure a sufficient supply of steam. It is also inconvenient to take rubber products out of the tank, resulting in insufficient practicality. The pressure control and depressurization structure of the vulcanizing tank is also complex. Therefore, a steam-heated vulcanizing tank for rubber manufacturing is proposed here.

Lifting lugs 3 are welded to both sides of the upper middle portion of the tank cover 2. A connecting pipe 4 is welded to the upper end of the tank cover 2 on one side of the lifting lug 3. A pressure gauge 5 is installed at the upper end of the connecting pipe 4. A safety valve 6 is installed on the side wall of the connecting pipe 4. A pressure relief valve 7 is installed on the side wall of the connecting pipe 4 above the safety valve 6. A steam tank 8 is bolted to one side of the lower end of the tank body 1. A heater 9 is installed inside the lower end of the steam tank 8. A liquid level sensor is installed on one inner wall of the steam tank 8. The steam tank 8 has a steam inlet pipe 11 on one side wall, the upper part of which is connected to the side wall of the tank body 1. The steam tank 8 has a water inlet pipe 12 on the side wall opposite to the steam inlet pipe 11. The tank body 1 located on one side of the steam tank 8 has a discharge pipe 13 welded to the lower end. The discharge pipe 13 has a discharge valve 14 on its side wall. The tank body 1 has a heating pipe 15 inside its side wall. The tank cover 2 has a support rod 16 in the middle of its lower end. The support rod 16 has mesh trays 17 equidistantly arranged on it. The tank body 1 has a temperature sensor 18 on the upper part of its inner wall.

[0015] The tank body 1 is surrounded by a support frame 19. The pressure gauge 5, pressure relief valve 7, and safety valve 6 are all connected to the connecting pipe 4 by threads. The pressure gauge 5 can sense the pressure inside the tank body 1 in real time and feed the sensed information back to the external control equipment of the vulcanizing tank. The safety valve 6 is an opening and closing component. It is normally closed under the action of external force. When the pressure inside the tank body 1 rises above the set value, the safety valve 6 will open to release the pressure in the tank body 1. When the pressure inside the tank body 1 is below the set value, the safety valve 6 will close again. When the pressure relief valve 7 is opened, the pressure inside the tank body 1 can be released through the pressure relief valve 7.

[0016] The cap at the top of the steam tank 8 is pressed between the top of the steam tank 8 and the bottom of the tank body 1. The heater 9 is embedded inside the bottom of the steam tank 8. When working, the heater 9 can heat the water in the steam tank 8. The liquid level sensor 10 is connected to the inner wall of the steam tank 8 by screws. The water inlet pipe 12 is welded to the side wall of the steam tank 8 and connected to the external pipeline. The two ends of the steam inlet pipe 11 are connected to the side wall of the steam tank 8 and the side wall of the tank body 1 by flanges, respectively. The steam generated by heating in the steam tank 8 will enter the tank body 1 through the steam inlet pipe 11. The liquid level sensor 10 can sense the water level in the steam tank 8 in real time and feed back the sensing information to the external control device of the vulcanizing tank. When the water level in the steam tank 8 is low to the set value, the external control device will control the external water supply device connected to the water inlet pipe 12 to supply water to the steam tank 8. When the water level in the steam tank 8 reaches the set value, the external control device will control the external water supply device connected to the water inlet pipe 12 to stop supplying water.

[0017] The discharge valve 14 is connected to the discharge pipe 13 by a thread, the heating pipe 15 is embedded in the side wall of the tank 1, and the temperature sensor 18 is connected to the inner wall of the tank 1 by a screw. When the discharge valve 14 is opened, the condensate in the tank 1 can be discharged through the discharge pipe 13. When the heating pipe 15 is working, it can heat the inside of the tank 1 to maintain the temperature required for rubber vapor vulcanization. The temperature sensor 18 can sense the temperature inside the tank 1 in real time and feed the sensed information back to the external control equipment of the vulcanizing tank. In this way, the external control equipment can adjust the heating pipe 15 according to the feedback information of the temperature sensor 18 so that the temperature inside the tank 1 can be maintained within the temperature range required for rubber vapor vulcanization.

[0019] Working Principle: This steam-heated vulcanizing tank for rubber manufacturing uses an external power supply and is controlled by an external control device. The tank lid 2 can be lifted by a hoisting device. The rubber products to be vulcanized can be placed on a mesh tray 17 and then placed inside the tank body 1. The tank lid 2 is then fixed with bolts. The steam generated in the steam tank 8 enters the tank body 1 through the steam inlet pipe 11 to steam-heat and vulcanize the rubber products inside the tank body 1. The liquid level sensor 10 can detect the water level in the steam tank 8 in real time and feed the detection information back to the external control device of the vulcanizing tank. When the water level in the steam tank 8 drops to the set value, the external control device will control the external control device connected to the water inlet pipe 12. The water supply equipment supplies water to the steam tank 8. When the water level in the steam tank 8 reaches the set value, the external control equipment will control the external water supply equipment connected to the water inlet pipe 12 to stop supplying water. This can effectively prevent insufficient steam in the tank 1. When the heating pipe 15 is working, it can heat the inside of the tank 1 to maintain the temperature required for rubber vapor vulcanization. The temperature sensor 18 can sense the temperature inside the tank 1 in real time and feed the sensing information back to the external control equipment of the vulcanizing tank. In this way, the external control equipment can adjust the heating pipe 15 according to the feedback information of the temperature sensor 18 so that the temperature inside the tank 1 can be maintained within the temperature range required for rubber vapor vulcanization.

[0020] Safety valve 6 is an opening and closing component. It is normally closed under external force. When the pressure inside tank 1 rises above the set value, safety valve 6 will open to release the pressure inside tank 1. When the pressure inside tank 1 is below the set value, safety valve 6 will close again. When vulcanization is complete, pressure relief valve 7 can be opened to release the pressure inside tank 1. Then, the bolts on tank cover 2 can be removed, and tank cover 2 can be lifted by hoisting equipment so that the vulcanized rubber product can be lifted out along with tank cover 2. When discharge valve 14 is opened, the condensate inside tank 1 can be discharged through discharge pipe 13.
