Detailed ways

In Fig. 1, Fig. 2, Fig. 3, the utility model is made of a two-position three-way valve 7, a heat storage tank and an air preheating tank. The air preheating box includes a tube group 5, a partition plate 4, an insulation layer 3, a casing 2, a pipe interface 1, a pressure sensor 11, and a temperature sensor 12, wherein the insulation layer 3 is fixedly connected to the casing 2, and the insulation layer 4 is Welded with the shell 2, the tube group 5 respectively penetrates the partition plate 4, the insulation layer 3 and the shell 2, and is welded with the partition plate 4 and the shell 2 at the penetration. The tube group 5 is composed of a certain number of tubes, which are arranged circumferentially at equal intervals along the inner wall of the insulation layer 3, and the number of layers arranged can be adjusted according to the size of the inner space of the air preheating box. In this embodiment, the pipes are arranged in two layers, the diameter of the pipes is φ30-φ40, and the wall thickness is 1-2 mm. The pipe material is high temperature resistant alloy steel. The hot water storage tank is composed of an inlet valve 8, an outlet valve 9 and a tank body 10. The water inlet of the inlet valve 8 is connected to the water outlet of the two-position three-way valve 7, and the water outlet of the inlet valve 8 is connected to the inner cavity of the tank body 10, and the tank body The water outlet of 10 is connected to the water inlet hole of the heat exchange tube group 5 of the air preheating box through the outlet valve 9.

When the vulcanization preheating device needs to be put into use, start the control switch of the two-position three-way valve 7 to connect the vulcanization preheating device with the outlet end of the superheated water pipeline in the vulcanizer, and the superheated water at about 120°C is preheated by air The pipe joint 1 of the box flows into the pipe group 5, and then flows out from the other end of the pipe group 5 through the pipe joint 1, so that the temperature in the air preheating box rises rapidly, and the tire blank is placed in the air preheating box, and waits for preheating. Take it out at 80-90°C and then enter the vulcanizing machine for vulcanization.
