Description
Technical Field
[0001] The present invention relates to the technical field of vulcanizers, and particularly relates to an automatic condensate discharging device for the internal temperature of steam in a tire vulcanizer. Background Art
[0002] A vulcanizer is an important device in the tire production process. During the vulcanization process, high-temperature steam needs to be introduced into the system, and the condensate discharging system needs to drain the condensed water after the steam enters the bladder. However, if the downtime is relatively long, the steam accumulated in the branch pipes will have heat loss, turning the saturated steam into unsaturated steam and generating condensed water at the same time. In this way, a large amount of wet saturated steam (containing a lot of water and having a large temperature difference from the saturated steam) will accumulate in the branch pipes during the production of the next tire and enter the inside of the bladder for tire vulcanization, resulting in heat transfer differences. And the condensate discharging system cannot drain the condensed water in these branch pipes in time, which will cause the temperature in the system to rise slowly after the vulcanization starts, and the temperature cannot reach the process requirements, thus affecting the quality of the tires and leading to the appearance of curved tires and under-vulcanized tires; moreover, if the condensate discharging system is in long-term condensate discharging, it will cause the steam pressure to drop and have a greater impact on steam leakage.

The one-way check valve 5 is set to prevent wastewater from flowing back; A second branch pipe 212 is arranged on the side of the main drain pipe 21, and a bladder internal pressure sensor 27 is arranged on the outer wall of the second branch pipe 212; the control panel 26 is respectively connected to the pressure detector 24, the pressure transmitter 25, and the bladder internal pressure sensor 27; A nitrogen recovery 4, a main drain 41, a vacuum cut-off valve 42, and a line recovery valve 43 are successively arranged on the outer wall of the main drain pipe 21; the nitrogen recovery 4, the main drain 41, the vacuum cut-off valve 42, and the line recovery valve 43 cooperate to recover the internal medium of the tire bladder 3 and completely empty the inside of the tire bladder 3; The drainage process during the above vulcanization process is as follows; The first step: adding steam: Start the condensate drain cut-off valve 61; drain the accumulated condensate in the pipeline in advance before the steam enters the tire bladder 3, which is complementary to the drainage of condensate during the vulcanization process and helps the drainage of condensate; Connect the steam source and the filter 13. The steam first passes through the filter 13 for filtration operation. The filtered steam enters the steam main pipe 11 and finally enters the tire bladder 3 through the end of the steam main pipe 11; If nitrogen needs to be switched, close the high-temperature cut-off valve 12 for steam inlet. Connect the nitrogen source and the nitrogen inlet pipe 7. Nitrogen enters the nitrogen inlet pipe 7 and finally enters the steam main pipe 11 through the end of the nitrogen inlet pipe 7, and finally enters the tire bladder 3 through the end of the steam main pipe 11; Step 2: Drain condensate: Condensate is generated during the heat absorption process of the tire bladder 3, and the generated condensate needs to be drained. The pressure detector 24 timely senses the pressure inside the condensate drain main pipe 21, and the capsule internal pressure sensor 27 senses the pressure inside the tire bladder 3. The pressure detection data is used to monitor the condensate drainage state, and the condensate is drained in time when detected. The above operations increase the internal temperature of the tire bladder 3, thereby reducing the temperature difference between the upper and lower parts of the tire bladder 3; When draining condensate, open the main drain valve 8 of the circuit. The steam inside the tire bladder 3 forms a vortex, and the condensate at the bottom can drive the condensate into the condensate drain main pipe 21 by swirling, and finally is drained through the condensate drain valve 22 and the condensate drain outlet pipe 23 in sequence: Step 3: Recover the internal medium of the tire bladder 3: After vulcanization, operate simultaneously through the nitrogen recovery 4, the main drain 41, and the vacuum cut-off valve 42 to recover the internal medium of the tire bladder 3 and completely empty the inside of the tire bladder 2; In the above invention, according to different tire production specifications and different vulcanization times, the condensate drainage frequency and interval time are automatically calculated. During the vulcanization process, the pressure detector 24 dynamically regulates the opening and closing of the condensate drain valve 22 to ensure that there is as little condensate accumulation as possible inside the tire bladder 3 when switching between nitrogen and steam; reduce the temperature difference between the upper and lower parts inside the tire bladder 3 and improve the tire vulcanization quality; Advantages of the above invention: 1. By automatically calculating the time, adjust the steam condensate drainage. Real-time detect the condensate drainage data and reduce the steam consumption. Under the condition of ensuring the steam quality, about 25% of the steam consumption per ton of tires can be saved.
[0020] 2. Improve the vulcanization process. Through technical detection, the durability and high-speed tests of the finished tires all pass the national standard detection and have obvious improvements.
[0021] 3. During the tire vulcanization process, it is easy to accumulate condensate in the lower tire side, lower tire shoulder and other parts, resulting in under-vulcanized parts. According to the foaming test situation, the theoretical vulcanization time is reduced by 5-10 seconds.
[0022] Through pre-drainage, dynamic regulation, and structural optimization, the present invention solves the problem of uneven heat transfer caused by the accumulation of condensate in the vulcanizer, significantly improving the quality and energy efficiency of tire vulcanization; while saving steam energy, it also improves the quality of tires.
