Description

Technical Field

[0001] This application relates to the field of vulcanization processing technology, specifically to a pipeline structure for a vulcanizing machine. Background Technology

[0002] A vulcanizing machine is a piece of equipment used in the rubber industry. Its main function is to heat and pressurize rubber materials, causing them to undergo chemical changes and transforming them into rubber products with specific properties. This process, called vulcanization, is a crucial step in the production of rubber products. Taking tire production as an example, during the vulcanization process, the vulcanizing machine primarily provides the internal heat source and pressure to the tire using high-temperature steam and high-pressure nitrogen. When the high-temperature steam comes into contact with the room-temperature tire carcass, it produces a large amount of condensate. This condensate has poor thermal conductivity. On the one hand, if the condensate is not drained in time, it will increase the temperature difference between the upper and lower molds of the vulcanizing machine, resulting in uneven heating of the rubber during vulcanization. On the other hand, if the condensate drainage time is too long, some steam may be released, wasting steam energy and affecting vulcanization efficiency. Summary of the Invention

[0003] This application provides a pipeline structure for a vulcanizing machine that allows for the discharge of condensate while retaining steam beneficial for vulcanization. This not only prevents uneven heating of tires during vulcanization due to the presence of condensate, thus avoiding a decline in tire quality, but also reduces steam loss.

[0004] One embodiment of this application provides a piping structure for a vulcanizing machine, including: a condensate draining pipe, which has a first inlet and a first outlet for allowing condensate generated during the vulcanizing process to enter and exit; and a drain valve, which is located inside the condensate draining pipe and is used to selectively allow condensate to pass through and exit from the first outlet, while preventing gas from passing through.

[0005] In some embodiments, the pipeline structure further includes: a gas detection device disposed between the steam trap and the first outlet for detecting whether gas is mixed in the condensate after passing through the steam trap, wherein the gas detection device can emit a detection signal when gas is detected; and a processing device connected to the gas detection device for emitting an alarm signal when the detection signal emitted by the gas detection device is received.

[0006] In some embodiments, the processing device includes: a processor connected to the gas detection device for identifying the detection signal and issuing a first control signal when the detection signal is of a preset type; and an alarm device connected to the processor for issuing a first reminder signal when the first control signal is received.

[0007] In some embodiments, the alarm device is a horn or a flashing light.

[0008] In some embodiments, the piping structure further includes an exhaust valve disposed between the drain valve and the gas detection device, the exhaust valve being used to selectively allow gas to pass through.

[0009] In some embodiments, the drain valve is signal-connected to the processor, which is configured to periodically acquire the number of times the drain valve has been opened since the vulcanizing machine was started, and send a second control signal to the alarm device when the number of openings exceeds a preset number, so that the alarm device issues a second reminder signal.

[0010] In some embodiments, the pipeline structure further includes: a branch pipeline connecting the condensate drain pipeline, wherein the second inlet and the second outlet of the branch pipeline are located on both sides of the drain valve; and a ball valve disposed within the branch pipeline.

[0011] In some embodiments, the pipeline structure further includes a shut-off valve disposed inside the condensate drain pipeline and located between the drain valve and the first outlet.

[0012] This application provides a piping structure for a vulcanizing machine, including a condensate drain pipe with a first inlet and a first outlet for condensate generated during the vulcanization process; and a steam trap, located inside the condensate drain pipe, selectively allowing condensate to pass through and be discharged from the first outlet while preventing gas from passing through. This application, through the coordinated operation of the condensate drain pipe and the steam trap, achieves the discharge of condensate while retaining steam beneficial to the vulcanization process. This not only prevents uneven heating of the tire during vulcanization due to the presence of condensate, thus avoiding a decrease in tire quality, but also reduces steam loss.

[0021] This utility model embodiment provides a piping structure for a vulcanizing machine, such as... Figure 1 As shown, the piping structure of the vulcanizing machine includes a condensate drain pipe 1, which is provided with a first inlet 10 and a first outlet 11 for the condensate generated during the vulcanization process to enter and exit; and a drain valve 2, which is located inside the condensate drain pipe 1 and is used to selectively allow condensate to pass through and be discharged from the first outlet 11, while preventing gas from passing through.

[0022] It's important to explain that a vulcanizing machine is a piece of equipment used in the rubber industry. Its main function is to heat and pressurize rubber materials, causing them to undergo chemical changes and transforming them into rubber products with specific properties. This process, called vulcanization, is a crucial step in the production of rubber products. Taking tire production as an example, during the vulcanization process, the vulcanizing machine primarily provides the internal heat source and pressure to the tire using high-temperature steam and high-pressure nitrogen. When the high-temperature steam comes into contact with the room-temperature tire carcass, it produces a large amount of condensate. This condensate has poor thermal conductivity. On one hand, if the condensate is not drained in time, it will increase the temperature difference between the upper and lower molds of the vulcanizing machine, resulting in uneven heating of the rubber during vulcanization. On the other hand, if the condensate drainage time is too long, some steam may be released, wasting steam energy and affecting vulcanization efficiency.

[0023] To solve the above-mentioned technical problems, in this embodiment, the piping structure of the vulcanizing machine provided by this solution mainly achieves the discharge of condensate pipe 1 and steam trap 2 through the cooperation of the pipe 1 and the steam trap 2. This not only avoids uneven heating of the tires during the vulcanization process due to the presence of condensate, which would lead to a decrease in tire quality, but also reduces the loss of steam.

[0024] The condensate drain pipe 1 is equipped with a first inlet 10 and a first outlet 11 for the condensate generated during the sulfidation process to enter and exit. It should be noted that the gas generated during the sulfidation process (specifically, high-temperature steam) also enters the condensate drain pipe 1 through the first inlet 10.

[0025] It should be noted that the traditional method for condensate drainage involves connecting a shut-off valve at the end of the condensate drain pipe 1 for intermittent condensate drainage. However, this method not only makes it difficult to control the timing of condensate drainage, but also results in the discharge of high-temperature steam that needs to be retained, leading to a waste of steam resources. To overcome the shortcomings of this existing technology, in this embodiment, a steam trap 2 is used instead of a shut-off valve. The steam trap 2 is installed inside the condensate drain pipe 1. Utilizing the characteristics of the steam trap 2, it can selectively allow condensate to pass through and be discharged from the first outlet 11, while preventing gas from passing through.

[0026] It should be explained that the steam trap 2 is an automatic valve used to drain condensate from a steam heating system while preventing steam leakage. It is a crucial component of the steam system and is essential for maintaining system efficiency and safety. The operating principle of the steam trap 2 is typically based on the differences in physical properties between condensate and steam, such as density, temperature, and phase changes. In one feasible embodiment, a float-type steam trap 2 (FT43-10) is selected. The float-type steam trap 2 is a common type of steam trap 2 that uses the rising and falling of a float to control the opening and closing of the valve.

[0027] In some embodiments, the pipeline structure further includes a gas detection device 3 disposed between the steam trap 2 and the first outlet 11 for detecting whether gas is mixed in the condensate after passing through the steam trap 2, wherein the gas detection device 3 can emit a detection signal when gas is detected; and a processing device (not shown in the figure) connected to the gas detection device 3 for emitting an alarm signal when receiving the detection signal emitted by the gas detection device 3.

[0028] In this embodiment, in order to prevent leakage of the steam trap 2, a leak detection device is added, which consists of a gas detection device 3 and a processing device.

[0029] The gas detection device 3 is located between the steam trap 2 and the first outlet 11. It is used to detect whether there is gas mixed in the condensate after passing through the steam trap 2, and the gas detection device 3 can send a detection signal when it detects gas. In one feasible embodiment, the gas detection device 3 is a pressure sensor (HTSV-1200, used to operate in high temperature environments).

[0030] The processing device is connected to the gas detection device 3 by signal, and is used to issue an alarm signal when it receives the detection signal from the gas detection device 3, so as to promptly remind the operator that there is a leakage problem in the steam trap 2.

[0031] In some embodiments, the processing apparatus includes:

[0032] A processor connected to the gas detection device 3 is used to identify the detection signal and issue a first control signal when the detection signal is of a preset type. In one feasible embodiment, the processor is an ATmega328P, a microcontroller used on the Arduino Uno board, which is suitable for processing analog signals and can read the analog output of the pressure sensor through an ADC (analog-to-digital converter).

[0033] An alarm device (not shown) is connected to the processor signal and is used to issue a first alert signal upon receiving a first control signal. In some feasible embodiments, the alarm device is a horn or a flashing light.

[0034] In some embodiments, the piping structure further includes an exhaust valve 4 disposed between the drain valve 2 and the gas detection device 3. The exhaust valve 4 is used to selectively allow gas to pass through. The characteristics of the exhaust valve effectively prevent liquid from entering and interfering with the detection accuracy of the gas detection device 3.

[0035] In some embodiments, the steam trap 2 is signal-connected to a processor. The processor is configured to periodically acquire the number of times the steam trap 2 has opened since the vulcanizing machine was started, and when the number of openings exceeds a preset number (e.g., 10 times), it sends a second control signal to an alarm device to cause the alarm device to issue a second reminder signal. By monitoring the number of times the steam trap 2 opens, operators can understand the working status of the steam trap 2. Frequent openings may indicate an abnormality in the steam trap 2. It should be noted that the first control signal and the second control signal can be an audible signal and a visual signal, respectively.

[0036] In some embodiments, the piping structure further includes a branch pipe 5 connected to the condensate drain pipe 1, with the second inlet and second outlet of the branch pipe 5 located on either side of the drain valve 2; and a ball valve 6 disposed within the branch pipe 5. The function of the ball valve 6 is to quickly drain condensate when there is a large amount of condensate inside the vulcanizing machine bladder, ensuring that the tires do not become defective due to the presence of condensate. The operator can see on the computer screen connected to the vulcanizing machine that the temperature detected inside the vulcanizing machine bladder is not rising, indicating a large amount of condensate, at which point the ball valve 6 needs to be opened.

[0037] In some embodiments, the piping structure further includes a shut-off valve 7 disposed inside the condensate drain pipe 1 and located between the steam trap 2 and the first outlet 11. The shut-off valve 7 plays a crucial role in the sulfidation process, especially during the use of the steam trap 2. The main function of the shut-off valve 7 is to control the flow of fluid; it can isolate the steam trap 2 when necessary, preventing leakage during use and thus reducing the probability of troubleshooting difficulties. The shut-off valve 7 is typically controlled by a processor and can automatically close and open according to a preset program; this is conventional technology and will not be described in detail.

[0038] This utility model embodiment provides a piping structure for a vulcanizing machine, including a condensate drain pipe 1, which has a first inlet 10 and a first outlet 11 for the condensate generated during the vulcanization process to enter and exit; and a steam trap 2, which is located inside the condensate drain pipe 1 and is used to selectively allow condensate to pass through and exit from the first outlet 11, while preventing gas from passing through. This embodiment, through the coordinated operation of the condensate drain pipe 1 and the steam trap 2, achieves the discharge of condensate while retaining steam beneficial to the vulcanization process. This not only avoids uneven heating of the tire during vulcanization due to the presence of condensate, thus preventing a decrease in tire quality, but also reduces steam loss.
