Description

Technical Field

[0001] The utility model relates to the field of tire vulcanization, in particular to a hot water supply system for giant tire vulcanization. Background Art

[0002] As is well known, hot water vulcanizers using the hot water vulcanization process must discharge the hot water in the bladder after completing tire vulcanization and before releasing the tire. As the pressure of the discharged hot water decreases, it vaporizes, removing a significant amount of heat. To reduce this heat loss, a common method is to first discharge the hot water into a 5-bar tank, then use the recovered hot water in the 5-bar tank to supplement the deaeration hot water tank. This method recovers hot water at a pressure above 5 bar to recycle the heat carried by the hot water. However, the hot water pressure in the deaeration hot water tank in the hot water supply system for jumbo tire vulcanization is less than 5 bar, making it more difficult to recover the hot water directly into the deaeration hot water tank than to use the 5-bar tank for recovery.

[0003] On the other hand, since the hot water capsules used to fill giant tire vulcanizers are generally large in volume, in order to prevent the process of filling the capsules with hot water from affecting the pressure of the hot water main and causing internal pressure fluctuations in other vulcanizers, these vulcanizers generally use a primary hot water automatic control valve to initially fill the capsules from the primary hot water main. Therefore, an independent primary hot water supply system is required. Due to the long vulcanization cycle of giant tires and the small number of vulcanizers, the primary hot water supply system is kept idling for a long time. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a hot water supply system for vulcanizing giant tires, which reduces equipment investment, heat loss and operation and maintenance costs.

[0005] The utility model solves the technical problem by adopting the following technical solution: a hot water supply system for giant tire vulcanization is provided with a deaerator hot water tank, which is characterized in that a water supply pump connected with the tank body is provided below the deaerator hot water tank, the water supply pump supplies water to the vulcanization zone through a circulating hot water supply main pipe, and is connected to the vulcanizers through circulating hot water inlet branch pipes of each vulcanizer in the vulcanization zone; the circulating hot water outlet branch pipes of each vulcanizer in the vulcanization zone are collected into a circulating hot water return main pipe, and return to the deaerator hot water tank through a pressure regulating device; the circulating hot water outlet branch pipes of each vulcanizer in the vulcanization zone are collected into a hot water recovery main pipe through valves and return to the deaerator hot water tank; the circulating hot water outlet branch pipes of each vulcanizer in the vulcanization zone are collected into a zero-pressure recovery main pipe through a drain valve and connected to the zero-pressure recovery tank, and the water outlet of the zero-pressure recovery tank enters the deaerator hot water tank through a water supply pump and a water supply pipe.

[0006] The beneficial effects of the present invention are that the equipment investment and heat loss are reduced by eliminating the 5-bar hot water recovery device; at the same time, the primary water supply device is eliminated, further reducing the power system investment and operation and maintenance costs.

[0010] In the figure, the utility model is provided with a deaerator hot water tank 1, and a water supply pump 9 connected to the tank body is provided below the deaerator hot water tank 1. The water supply pump 9 supplies water to the vulcanization zone through a circulating hot water supply main pipe 10, and is connected to the vulcanizer through the circulating hot water inlet branch pipes of each vulcanizer in the vulcanization zone; the circulating hot water outlet branch pipes of each vulcanizer in the vulcanization zone are collected to the circulating hot water return main pipe 3, and return to the deaerator hot water tank 1 through the pressure regulating device 2; the circulating hot water recovery branch pipes of each vulcanizer in the vulcanization zone are respectively collected to the hot water recovery main pipe 4 through the recovery valve and return to the deaerator hot water tank 1; the circulating hot water discharge branch pipes of each vulcanizer in the vulcanization zone are respectively collected to the zero-pressure recovery main pipe 5 through the drain valve and connected to the zero-pressure recovery tank 7, and the water outlet of the zero-pressure recovery tank 7 enters the deaerator hot water tank 1 through the water supply pump 8 and the water supply pipe 6.

[0011] The water supply pump 9 of the present invention supplies the deoxygenated hot water in the deoxygenated hot water tank 1 to the vulcanizing area through the circulating hot water supply main 10, and enters the vulcanizing machine through the circulating hot water inlet branch pipes of each vulcanizing machine in the vulcanizing area; the circulating hot water outlet branch pipes of each vulcanizing machine in the vulcanizing area are collected into the circulating hot water return main 3, and the circulating hot water therein returns to the deoxygenated hot water tank 1 through the pressure regulating device 2; when a certain vulcanizing machine finishes the hot water circulation and needs to discharge the residual hot water, it is first discharged to the hot water recovery main 4 for a certain period of time, and then discharged to the zero-pressure recovery main 5.

[0012] The hot water discharged from each vulcanizer in the vulcanization zone to the hot water recovery main 4 directly enters the deaeration hot water tank 1 to participate in the hot water circulation supply, and all the heat contained is reused. Since the amount of water is relatively small, this process will not cause the pressure in the deaeration hot water tank 1 to increase.

[0013] The residual hot water with lower pressure in each vulcanizer in the vulcanization zone is discharged to the zero-pressure recovery tank 7 through the zero-pressure recovery main pipe 5, and can enter the deaeration hot water tank 1 through the water supply pump 8 and the water supply pipe 6 to replenish the liquid level.

[0014] Installing a vulcanizer in the vulcanization zone using a multi-stage gradual increase in internal pressure eliminates the need for a primary hot water supply system. This technology is described in Patent Publication No. CN118528587A, "Method for Adjusting Multi-stage Gradual Increase in Internal Pressure in a Hot Water Process Tire Vulcanizer," and is not detailed here.
