[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. The invention is provided with a drainage box. Before vulcanizing rubber products, by driving the fan blades inside the drainage box to rotate, the air inside the tank body can be extracted. Then, through the function of the filter screen plate, the air is filtered to block and remove the dust and impurities floating in the air. Moreover, due to the rotation of the fan blades, an air current will be formed inside the tank, increasing the air flow inside the tank, so that the dust and impurities attached to the inner wall of the tank body and the frame can be induced to fly and then removed, improving the cleanliness inside the tank body, being beneficial to the vulcanization quality of rubber products. At the same time, after the vulcanization trolley is pushed into the tank body, the top box at the top of the vulcanization trolley will be attached and connected to the air delivery box, so that the air extracted by the rotation of the fan blades will be diverted into the square through holes of the top box. Thus, when the air flows through the square through holes, it will push the rotating plate to rotate, causing the central shaft to drive the vertical rod to rotate, and the rubber products fixedly placed on each vertical rod will rotate accordingly, enabling the air on the rubber surface to flow rapidly, facilitating the dust and impurities on the rubber products to fly into the air, improving the vulcanization quality of rubber products. At the same time, during the vulcanization process of rubber products, through the function of the drainage box, the vulcanization steam inside the tank body can flow, and it drives the vertical rod to drive the rubber products to rotate self - sufficiently, enhancing the flow ability of the vulcanization steam around the rubber products. This can not only improve the heat exchange effect but also make the temperature inside the tank uniform in each part, thereby improving the vulcanization quality of rubber products.

[0027] 2. The invention is provided with a bottom box, in which a heat conduction pipe is arranged. Thus, after the rubber products are vulcanized, by outputting the vulcanization steam to the recovery cavity of the bottom box, through heat exchange, the heat inside the vulcanization steam is fully utilized to heat the water body in the heat conduction pipe, enabling the recovery and utilization of the waste heat of the vulcanization steam, improving the practicability. And a distributor is arranged in the recovery cavity, which can evenly discharge the vulcanization steam to one end of the recovery cavity, being beneficial to the uniformity of heating the water body in the heat conduction pipe. At the same time, the heat conduction pipes are arranged in a curved manner, increasing the flow path of the water body in the heat conduction pipes, prolonging the heating time, and increasing the waste heat recovery capacity.

[0041] A working method of a vulcanizing tank for rubber product processing includes the following steps:

[0042] S1: Fix the rubber product on the vulcanizing trolley and push it into the tank body 1, and then close the tank cover 2;

[0043] S2: Then drive the fan blades 23 to rotate to form an air flow in the tank, and make the dust and impurities attached to the inner wall of the tank body 1 and the frame 15 fly away and be removed;

[0044] S3: At the same time, the flowing air generated by the rotation of the fan blades 23 will push the rotating plate 21 to rotate when flowing through the square through-hole 20, so that the rubber product rotates, which is convenient for the dust and impurities on the rubber product to fly into the air and be removed;

[0045] S4: Then start the vacuum pump 6 to create a vacuum state inside the tank body 1, and then transport high-temperature and high-pressure vulcanizing steam into the tank body 1 through the steam delivery pipe 5 to vulcanize the rubber products.

[0046] S5: After the rubber products are vulcanized, relieve the pressure inside the tank body 1 and let the vulcanizing steam be discharged through the exhaust pipe 33 and evenly discharged into the bottom box 4.

[0047] S6: Through the effect of heat exchange, the vulcanizing steam conducts heat to the water body inside the heat conduction pipe 37 to recover and utilize the waste heat of the vulcanizing steam, and then the vulcanizing steam is output through the output pipe 39.

The transmission shaft 30 rotates. Through the meshing transmission of the first gear 31 and the second gear 32, the rotating shaft 28 rotates, so that the fan blade 23 rotates, extracting the air inside the tank body 1 into the diversion box 19. Through the function of the filter screen plate 24, the air is filtered, retaining and removing the dust and impurities floating in the air, and falling into the impurity storage box 10. And under the rotation of the fan blade 23, an air current will be formed in the tank, increasing the air flow inside the tank, so that the dust and impurities attached to the inner wall of the tank body 1 and the frame 15 can be induced to fly and then removed, improving the cleanliness inside the tank body 1, which is beneficial to the vulcanization quality of the rubber products. At the same time, the air extracted by the rotation of the fan blade 23 will be diverted through the air delivery box 18 into the square through-hole 20 of the top box 12. Thus, when the air flows through the square through-hole 20, it will push the rotating plate 21 to rotate, so that the central shaft 22 drives the vertical rod 13 to rotate, and the rubber products fixedly placed on each vertical rod 13 will rotate accordingly, making the air on the surface of the rubber products flow rapidly, facilitating the dust and impurities on the rubber products to fly into the air, improving the vulcanization quality of the rubber products. Then start the vacuum pump 6, extract the air inside the tank body 1 through the suction pipe 7 to create a vacuum state inside the tank body 1, and then through the function of the steam delivery pipe 5, transport high-temperature and high-pressure vulcanizing steam into the tank body 1 to vulcanize the rubber products. After the rubber products are vulcanized, open the valve on the exhaust pipe 33, relieve the pressure inside the tank body 1 and let the vulcanizing steam be discharged through the exhaust pipe 33. Through the function of the distributor 35, the vulcanizing steam is evenly discharged into the recovery chamber 34 of the bottom box 4. Through the effect of heat exchange, make full use of the heat inside the vulcanizing steam to heat the water body inside the heat conduction pipe 37, so that the waste heat of the vulcanizing steam can be recovered and utilized, improving the practicability. Then the vulcanizing steam is output through the output pipe 39.
