[0046] A condensing device, including a condenser assembly and a humidity detection assembly, wherein the inlet end of the condensing device is connected to the pressure stabilizing device and is used to condense steam;

[0047] The return water tank 22 is connected to the outlet of the condensing device through a pipeline, and is used to recover the water condensed by the condensing device. An insulation layer is provided on the outer wall of the return water tank 22. A liquid level sensor is provided in the return water tank 22.

[0048] The recovery device 23 is used to receive the gas discharged from the condensing device, and the recovery device 23 is filled with an alkaline solution capable of absorbing sulfur dioxide, such as sodium hydroxide solution or lime water;

[0049] A control cabinet, which has a controller and control circuit inside.

[0050] In this embodiment, the vulcanizer 2 includes an outer shell and an inner mold, an external pressure chamber is formed between the outer shell and the inner mold, a steam chamber is formed on the inner side of the inner mold, and the transmission belt is sleeved on the inner mold for vulcanization; the inflation port is connected to the external pressure chamber, the steam interface is connected to the steam chamber, and the outer shell is provided with an air outlet connected to the external pressure chamber and a steam outlet connected to the steam chamber, the air outlet and the steam outlet are connected in parallel to form an exhaust port, and the vulcanizer 2 is also provided with an external pressure detector for detecting the external pressure chamber and an internal pressure detector for detecting the steam chamber.

[0051] The hot steam and pressurized hot air entering and exiting the vulcanizer 2 are controlled by the electric control valve, and the external pressure detector, the internal pressure detector and the electric control valve cooperate to form an environment with a certain temperature and pressure in the vulcanizer 2.

[0111] Embodiment 10:

[0112] This embodiment provides a vulcanization method for a transmission belt vulcanization device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0113] The method for the condensing device to control the switching valve 26 according to the relationship between the relative humidity RH discharged from the primary exhaust port and the humidity threshold RHX is:

[0116] The calculation method of the average data RH1 of each group of detection components is:

[0117] When the number of detection components is 2 groups, the average data RH1 of the detection component located on the side close to the primary exhaust port is obtained by removing the maximum value of the data detected by the multiple detection sensors 25 in the group and averaging it; the average data RH1 of the detection component located on the other side is obtained by removing the minimum value of the data detected by the multiple detection sensors 25 in the group and averaging it;

[0118] When the number of detection components is 3 groups, the average data RH1 of the detection component located on the side close to the primary exhaust port is the average of the data detected by several detection sensors 25 in the group after removing the maximum value; the average data RH1 of the detection component located in the middle position is the average of the data detected by several detection sensors 25 in the group; the average data RH1 of the detection component located on the other side is the average of the data detected by several detection sensors 25 in the group after removing the minimum value.

[0119] In this embodiment, since the position near the primary exhaust port is close to the first condenser 20, there may be a certain data deviation, so the controller removes the maximum value and then calculates the average when calculating the average data RH1 of this position; and the probability of error on the other side far away from the primary exhaust port is low, so when calculating the average data RH1, the minimum value is removed, and then the average is calculated through multiple RH1s to obtain the relative humidity RH more accurately; by comparing the relative humidity RH with the humidity threshold RHX, the state of the switching valve 26 is controlled.
