A water circulation device for tire vulcanization

Abstract

The invention discloses a water circulation device for tire vulcanization. The water circulation device comprises two vulcanization machine assembly platforms, a vulcanization tank, a hot water recycle tank and a temperature sensor, wherein two ends of the vulcanization tank in the length direction are separately provided with a water inlet and a water outlet, and the vulcanization tank is arranged between the two vulcanization machine assembly platforms; the hot water recycle tank is connected with the water outlet of the vulcanization tank; a hot water discharging pipeline is arranged on the lower side of the hot water recycle tank; a steam emission pipeline is arranged on the hot water discharging pipeline; the steam emission pipeline comprises multiple steam emission pipes; a cold water inlet pipe is also arranged on the hot water recycle tank; and the temperature sensor is arranged in the hot water recycle tank. Compared with the prior art, the water circulation device is advantaged in that temperature of a water flow in the hot water recycle tank is sensed through the temperature sensor; if the temperature exceeds preset temperature, cold water is added into the hot water recycle tank through the cold water inlet pipe; the phenomenon that water temperature in the hot water recycle tank reaches 100 DEG C, and water boils intensely, so that the hot water recycle tank is impacted is avoided; and meanwhile, the multiple steam emission pipes are arranged, so that multi-point decompression can be realized, and safe production is ensured.

Description

technical field [0001] The invention belongs to the technical field of tire building equipment, and in particular relates to a water circulation device for tire vulcanization. Background technique [0002] Tire vulcanization is the last step in the tire manufacturing process, which largely determines the quality of the tire. Hot water sulfuration is a relatively common sulfuration process. In this sulfuration process, it is very important for the stability of the water circulation system. At present, the water circulation system uses high pressure (24kg / cm 2 ) high temperature (about 185°) hot water to add sulfur, in the above process, the hot water must pass through the hot water recovery tank for recycling, and the pressure in the hot water recovery tank is atmospheric pressure, which will bring a The problem is that the temperature in the hot water recovery tank generally exceeds 100°C. At this time, it will cause violent boiling, which will reduce the utilization rate ...

Problems solved by technology

At present, the water circulation system uses high pressure (24kg / cm 2 ) high temperature (about 185°) hot water to add sulfur, in the above process, the hot water must pass through the hot water recovery tank for recycling, and the pressure in the hot water recovery tank is atmospheric pressure, which will bring a The problem is that the temperature in the hot water recovery tank generally exceeds 100°C. At this time, it will cause violent boiling, which will reduce the utilization rate of the recovery water pump from 100% to about 40%, and the water pump will keep running for a long time. At the same time, it causes the instability of the water circulation system, and the hot water recovery tank overflows, which increases the supply of hot water, reduces the utilization rate, and wastes water resources; there is also a problem that when the hot water recovery tank is violently When boiling, because the diameter of the existing exhaust pipe is about 3 inches and the diameter is small, there is a phenomenon that the pressure cannot be released in time, and the pressure continues to rise, causing impact on the tank body, while the traditional tank body is a rectangular steel plate welded production, the bearing capacity is poor, and the tank body is prone to rupture, resulting in hot water spraying and production accidents
