Description

Technical Field

[0001] This utility model relates to the technical field of steam pot vulcanizing machines, and in particular to a device for recovering waste heat from external condensation in a steam pot vulcanizing machine. Background Technology

[0002] The steam pot vulcanizing machine is an open external temperature device, with the steam pot section exposed, resulting in a large amount of air inside each time the mold is closed. During the tire vulcanization process, steam is added to heat the mold in the steam chamber. To ensure the stability of the temperature inside the steam chamber (i.e., the external temperature), the condensate in the steam chamber needs to be drained. The external temperature condensate draining device for the steam pot vulcanizing machine proposed in the existing technology announcement number CN204640630U includes a condensate drain pipe, which branches into two parallel first condensate drain pipes and a second condensate drain pipe. The outlet ends of the first and second condensate drain pipes are merged into the condensate drain pipe. A first shut-off valve is installed at the inlet end of the first condensate drain pipe, and a second shut-off valve is installed at the inlet end of the second condensate drain pipe. A steam trap is installed at the outlet end of the first condensate drain pipe, and a two-position pneumatic shut-off valve is installed at the outlet end of the second condensate drain pipe. The condensate drain pipe is connected to the main condensate drain pipe, and the steam trap and the two-position pneumatic shut-off valve are connected to the controller via wiring. However, tire hair, rubber edges, and impurities generated during tire production can enter the drainage device during the drainage process, causing blockages. Therefore, the drain valve needs to be cleaned regularly, which affects its use. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a steam pot-type vulcanizing machine external temperature condensate waste heat recovery device that saves steam heat, reduces steam consumption, conserves steam, and reduces waste.

[0004] This utility model discloses a waste heat recovery device for external condensate discharge of a steam-type vulcanizing machine, comprising a storage tank, a connecting pipe, a venting assembly, a filter assembly, and a recovery assembly. The connecting pipe is connected to the upper part of the storage tank and is connected to the condensate discharge port of the steam-type vulcanizing machine. The venting assembly is connected to the top of the storage tank, the filter assembly is installed inside the storage tank, and the recovery assembly is connected to the bottom of the storage tank. The vapor-liquid mixture condensed from the vulcanizing machine enters the storage tank through the connecting pipe for collection. The air, the least dense component, is discharged through the venting assembly at the top. The filter assembly inside the storage tank filters out internal impurities. The recovery assembly utilizes the principle that flash steam is denser than air but less dense than water for recovery, achieving classified discharge of condensate, rationally saving steam heat, reducing steam consumption, and conserving steam. The amount of condensate recovered is increased, reducing waste and eliminating noise and heat during the condensate discharge process.

[0005] Preferably, the venting assembly includes a venting pipe and an air venting valve. The venting pipe is connected to the top of the storage tank, and the air venting valve is installed on the venting pipe. The other end of the venting pipe is connected to the condensate system. The vapor-liquid mixture enters the storage tank, is collected, and then the air with the lowest density is discharged through the air venting valve.

[0006] Preferably, the filter assembly includes a cleaning port and a filter screen. The filter screen is installed inside the lower side of the liquid storage tank, and the cleaning port is installed on the upper right side of the liquid storage tank. The inlet of the cleaning port is located above the filter screen. The filter screen can filter internal impurities, and the cleaning port facilitates the cleaning of impurities, thus improving practicality.

[0007] Preferably, the recovery assembly includes a steam recovery pipe, a condensate drain pipe, and a condensate drain shut-off valve. The input end of the steam recovery pipe is connected to a storage tank, and a valve is installed on the steam recovery pipe. The other end of the steam recovery pipe is connected to a flash steam recovery system. A condensate drain pipe is connected to the bottom of the storage tank and is connected to the condensate recovery system. A condensate drain shut-off valve is installed on the condensate drain pipe. Utilizing the principle that flash steam is denser than air but less dense than water, the flash steam is recovered and reused by entering the flash steam recovery system through the steam recovery pipe. Condensate is recovered by entering the condensate recovery system through the condensate drain pipe. This separation and classification of air, flash steam, and condensate maximizes heat recovery and fully utilizes different recovery media, reducing steam consumption.

[0008] Preferably, it also includes an upper liquid level condensate drain electrode and a lower liquid level condensate drain electrode, which are respectively installed on the right side wall of the storage tank and located on the upper and lower sides of the filter screen; the upper liquid level condensate drain electrode and the lower liquid level condensate drain electrode are used to detect the liquid level of the condensate inside the storage tank so that the condensate inside can be drained according to the liquid level.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the vapor-liquid mixture of the condensate from the vulcanizing machine enters the storage tank through the connecting pipe for collection, and the air with the lowest density is discharged through the top venting component. The filter component inside the storage tank can filter internal impurities, and the recovery component uses the principle that flash steam is denser than air but less dense than water to recover it. This realizes the classified discharge of the condensate removal device, reasonably saves steam heat, reduces steam consumption, and saves steam; the amount of condensate recovered is increased, reducing waste and eliminating noise and heat in the condensate removal process.

The condensate is fed into the condensate recovery system through the condensate drain pipe 6 for recovery. By separating and classifying the air, flash steam, and condensate, more heat is recovered, and different recovery media are fully utilized, reducing steam consumption. The filter screen 11 can filter internal impurities, and the cleaning port 10 facilitates the cleaning of impurities, improving practicality. The condensate level inside the storage tank 1 is detected by the upper liquid level discharge electrode 8 and the lower liquid level discharge electrode 9, so that the internal condensate can be discharged according to the liquid level.

During operation, the vapor-liquid mixture condensed from the vulcanizing machine enters the storage tank 1 through the connecting pipe 2 for collection.

After the vapor-liquid mixture enters the storage tank 1 for collection, the air with the lowest density is discharged through the air vent valve 4. Utilizing the principle that flash steam is denser than air but less dense than water, the flash steam enters the flash steam recovery system through the steam recovery pipe 5 for recovery and reuse. The condensate is input into the condensate recovery system through the condensate drain pipe 6 for recovery. By separating and classifying the air, flash steam, and condensate, the heat is recovered more efficiently, and different recovery media are fully utilized. The condensate level inside the storage tank 1 is detected by the upper liquid level condensate discharge electrode 8 and the lower liquid level condensate discharge electrode 9. The filter screen 11 can filter internal impurities, and the cleaning port 10 facilitates the cleaning of impurities.
