Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tire production, and in particular to a nitrogen circulation heating device for an aircraft tire shaping and vulcanizing machine. Background Technology

[0002] The rubber used in aircraft tires needs to undergo vulcanization during the production process. During vulcanization, nitrogen needs to be circulated and heated. This is usually achieved through methods such as the nitrogen circulation heating system for a tire shaping vulcanizing machine disclosed in utility model patent CN217967939U and the high-efficiency energy-saving electric heating nitrogen vulcanization system for tires disclosed in utility model patent CN220841539U.

[0003] However, during use, it was found that the existing nitrogen circulation heating device has a relatively simple structure and a short heating time, which affects the nitrogen exhaust speed and the vulcanization speed of the rubber, resulting in poor practicality. Therefore, there is an urgent need for a nitrogen circulation heating device for aircraft tire shaping vulcanizing machines to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a nitrogen circulation heating device for an aviation tire shaping vulcanizing machine. The nitrogen is discharged into a filtration mechanism to filter impurities in the nitrogen, and then discharged into a heat preservation mechanism to heat the nitrogen through a heating mechanism before being discharged. This improves the practicality of the equipment.

[0005] This utility model discloses a nitrogen circulation heating device for an aviation tire shaping vulcanizing machine, which includes a heat preservation mechanism, a heating mechanism, and a filtering mechanism. The heat preservation mechanism is installed on the filtering mechanism, and the heating mechanism is installed in the heat preservation mechanism.

[0006] The filtration mechanism filters and removes impurities from the nitrogen gas, while the heating mechanism, in conjunction with the heat preservation mechanism, heats the nitrogen gas.

[0007] Nitrogen gas is discharged into the filtration mechanism to filter out impurities. Then, the nitrogen gas is discharged into the insulation mechanism to heat it. Finally, the heated nitrogen gas is discharged, thereby improving the practicality of the equipment.

[0008] Preferably, the heating mechanism includes a flow guide box, a flow guide cylinder, multiple sets of heating elements, and a gas delivery mechanism.

One end of the multiple sets of heating elements is located in the flow guide cylinder, and the other end of the multiple sets of heating elements is located between the flow guide cylinder and the flow guide box. Nitrogen gas is discharged into the bottom of the flow guide cylinder through the gas delivery mechanism, so that the multiple sets of heating elements heat the nitrogen gas. Then, the nitrogen gas rises to the top of the flow guide cylinder and enters the flow guide box. The nitrogen gas flows downward in the flow guide box, and the multiple sets of heating elements continuously heat the nitrogen gas. Then, the nitrogen gas is discharged into the heat preservation mechanism through the exhaust holes at the bottom of the heating elements.

Filtered nitrogen flows sequentially through the second delivery pipe, the electrically controlled valve, the third delivery pipe, the exhaust passage in the guide tube, and the first delivery pipe, before entering the air plate. The nitrogen is then sprayed out through multiple sets of nozzles.

[0010] Preferably, the filtration mechanism includes a filter box, a support, multiple sets of filter plates, multiple sets of sealing plates, an air inlet valve, an inspection door, and a rotating mechanism. The support and air inlet valve are both installed at the bottom of the filter box, the rotating mechanism is installed inside the filter box, the multiple sets of filter plates are all installed on the rotating mechanism, the multiple sets of sealing plates are all installed on the inner wall of the filter box, and the inspection door is installed on the filter box.
