Abstract
Description
Technical Field
[0001] The utility model relates to a steam-water separation device for a tire vulcanizer, belonging to the technical field of tire machinery accessories. Background Art
[0002] In the tire industry, steam is an important heat source and is mainly used in the production of tire vulcanization. The tire vulcanization process requires the external pressure steam pressure of the vulcanizer to be 0.4-0.5Mpa and the temperature to be 145-160℃; during the vulcanization process, saturated steam is introduced into the external pressure steam chamber of the tire vulcanizer for vulcanization. After releasing heat, the saturated steam turns into condensed water, and new saturated steam continues to enter the external pressure steam chamber of the vulcanizer to maintain the vulcanization pressure and temperature.
[0003] Steam condensate is discharged into the condensate recovery pipe through the steam trap valve group of the tire vulcanizer. When it is collected in the non-pressurized condensate recovery tank, part of the steam will inevitably be discharged directly into the condensate recovery pipe through the steam trap group, resulting in a waste of heat source steam; at the same time, when the steam trap group is discharged, the pressure and temperature of the external pressure steam chamber of the vulcanizer will fluctuate, affecting the stable temperature conditions required for tire vulcanization. Usually, the amount of condensate recovered is 85% of the amount of external pressure steam used, indicating that 15% of the steam is lost or evaporated during the condensate recovery process. In tire companies, the cost of steam exceeds 50% of the total energy cost of tire companies. Reducing the consumption of steam can directly reduce the production cost of tires, which is of great significance to the development of enterprises. Summary of the invention

[0026] like Figure 1 As shown, a steam-water separation device for a tire vulcanizer includes a liquid inlet pipe 1, a buffer tank 4, a separation and drainage tank 9 and a liquid drainage pipe 15;
[0027] One end of the buffer tank 4 is connected to the bottom of the vulcanizer steam chamber through a liquid inlet pipe 1, and a pneumatic shut-off valve 2 for controlling the on-off of the pipeline is installed on the liquid inlet pipe 1. The condensed water and a trace amount of steam in the vulcanizer steam chamber enter the buffer tank 4 through the liquid inlet pipe 1, and the other end of the buffer tank 4 is connected to the separation and drainage tank 9 through a plurality of connecting pipes;
[0028] The bottom of the separation and drainage tank 9 is connected with a drain pipe 15, on which a one-way valve 13 and a pneumatic shut-off valve 14 are installed. The end of the drain pipe 15 is connected with a condensate recovery pipe. The condensate and a trace amount of steam in the buffer tank 4 flow into the separation and drainage tank 9 through the connecting pipe. The condensate and steam are separated by the separation and drainage tank 9, and the separated condensate flows into the condensate recovery pipe through the drain pipe 15 for recovery.
[0029] As an improvement of the embodiment, one end of the liquid inlet pipe 1 is connected to the bottom end of the vulcanizer steam chamber, and the other end is installed with an elbow, the elbow is located above the interior of the buffer tank 4, and the bending direction of the elbow is toward the side wall of the buffer tank 4. In addition, an inclined baffle 5 is installed above the interior of the buffer tank 4, and a plurality of holes are opened on the baffle 5. After the condensed water and a trace amount of steam discharged from the vulcanizer steam chamber pass through the elbow at the bottom of the liquid inlet pipe 1 and the baffle 5 with a porous structure, the impact and swirl are greatly reduced, thereby ensuring the stability of the liquid level in the buffer tank 4.
[0030] As an improvement of the embodiment, a branch pipe is connected in parallel to the liquid inlet pipe 1, and a manual stop valve 3 is installed on the branch pipe. The manual stop valve 3 is arranged in parallel with the pneumatic shut-off valve 2 installed on the liquid inlet pipe 1. The liquid inlet pipe 1 can be opened and closed by the pneumatic shut-off valve 2; the manual stop valve 3 can be used to manually open and close the pipeline during maintenance or emergency situations.
[0031] As an improvement of the embodiment, the connecting pipe includes a low-position connecting pipe 7 and a high-position connecting pipe 6; the low-position connecting pipe 7 is connected to the bottom of the buffer tank 4 and the middle of the separation drainage tank 9, and the high-position connecting pipe 6 is connected to the upper part of the buffer tank 4 and the upper part of the separation drainage tank 9. By setting the high and low-position connecting pipes, the liquid flow between the buffer tank 4 and the separation drainage tank 9 can be ensured to be smoother.
[0032] As an improvement of the embodiment, Figure 1 As shown, a float type liquid level gauge 8 is installed on the separation drainage tank 9, and the float type liquid level gauge 8 is used to control the liquid level of condensed water in the separation drainage tank 9 between a low liquid level 12 and a high liquid level 16. The high liquid level 16 is located below the high-level connecting pipe 6, and the low liquid level 12 is located at 1 / 3 of the volume of the separation drainage tank 9. During operation, condensed water is always retained in the separation drainage tank 9 to separate steam and condensed water in the form of a water seal.
[0033] As an improvement of the embodiment, a pressure sensor 10 and a temperature sensor 11 are installed at the lower part of the separation drainage tank 9. The pressure and temperature of the separation drainage tank 9 are detected by the pressure sensor 10 and the temperature sensor 11. According to the set upper and lower limit temperatures and pressures, the pneumatic shut-off valve 1 2 and the pneumatic shut-off valve 2 14 can be opened and closed in an emergency, and an alarm can be given to ensure safety and ensure the normal use of the separation drainage tank 9.
[0034] Specific working process:
[0035] When steam condensate is collected in the vulcanizer steam chamber, close the pneumatic shut-off valve 2 14, open the pneumatic shut-off valve 1 2, and connect the steam condensate, buffer tank 4, separation drain tank 9 and vulcanizer steam chamber as a whole through multiple pipelines. The separation drain tank 9 is located at the lowest end. Through the liquid inlet pipe 1 connected to the bottom of the vulcanizer steam chamber and the high and low position connecting pipes, the condensate is continuously collected in the separation drain tank 9 until it reaches the high liquid level 16 of the separation drain tank 9;
[0036] When discharging condensed water, close the pneumatic shut-off valve 12 and open the pneumatic shut-off valve 2 14. Under the action of the residual pressure inside the separation and drainage tank 9, the condensed water in the separation and drainage tank 9 passes through the one-way valve 13, the pneumatic shut-off valve 2 14 and the drain pipe 15 and is discharged into the condensed water recovery pipe; when the condensed water in the separation and drainage tank 9 is discharged to the low liquid level 12, the pneumatic shut-off valve 2 14 is closed and the pneumatic shut-off valve 2 is opened, and the process of collecting and discharging condensed water is repeated in this way.
[0037] Among them, the connection position between the drain pipe 15 and the condensate return pipe is much higher than the height of the separation drain tank 9. Even in the non-operating pressure-free state, due to the effect of the liquid level pressure difference, it can ensure that there is water in the separation drain tank 9, so that the steam-water separation device of the utility model can separate steam and condensate when it is turned on in any state.
[0038] The utility model of the steam-water separation device for tire vulcanizer realizes the complete separation of steam and condensed water. Compared with the steam trap valve group of the traditional tire vulcanizer, it reduces the steam consumption by more than 10%, saving the production cost. The whole condensed water collection and discharge process does not directly connect the vulcanizer steam chamber and the outside world, so that the pressure and temperature in the vulcanizer steam chamber tend to be stable, ensuring the production quality; the structure is simple, and the use and maintenance costs are very low.
[0039] In addition, those skilled in the art will understand that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments also means being within the scope of protection of the present utility model and forming different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
