Embodiment Construction

[0012] A dynamic sealing structure for a high-temperature furnace. The structure is composed of a static fixing part, a dynamic rotating part, a sealing packing, a compression retaining ring, a pressurized elastic bag and a cooling pressure pump station. The static fixing part and the dynamic rotating part The connection part is provided with a sealing packing, a compression retaining ring and a pressurized elastic bag in sequence. The pressurized elastic bag is inlaid and fixed on the sealing cover, and the sealing cover is fixed on the static fixture by screws. The liquid inlet and the The liquid outlet is connected to the cooling pressure pump station through a pipeline. A back pressure valve is set on the pipeline of the liquid outlet, and a flow valve is set on the pipeline of the liquid inlet. By adjusting the back pressure valve and the flow valve, the pressure and flow can be realized. Adjustment.

Abstract

The invention discloses a dynamic sealing structure for a high-temperature kiln. The dynamic sealing structure for the high-temperature kiln is suitable for a dynamic sealing industry of high-temperature rotating kiln in the high temperature field of chemical industry; the structure is composed of a dynamic rotating part, a static fixing part, sealing packing, a compression retaining ring, a pressurized elastic bag and a cooling pressure pump station. A high-pressure cooling medium is conveyed to the pressurized elastic bag by the cooling pressure pump station, so that the pressurized elasticbag is expanded to push the compression retaining ring to apply pressure on the sealing packing, and thus the sealing effect is realized, the dynamic sealing can be completed, and meanwhile, liquid ofthe pressure pump station is used as the cooling medium, so that the sealing is not affected by the high temperature.

Description

technical field [0001] The invention relates to a high-temperature kiln dynamic sealing structure, which belongs to the dynamic sealing industry of kiln equipment in the chemical industry, mining and petroleum fields, and specifically relates to a dynamic sealing structure form of a thermal kiln butt joint. Background technique [0002] For a long time, the problem of butt sealing of high-temperature equipment has been troubled by technical engineers. The sealing of high-temperature furnaces is usually sealed by mechanical seals and high-temperature-resistant elastic materials, but mechanical seal materials are often affected by high-temperature thermal expansion, which will lead to seal failure or attenuation of the effect. Leakage accidents are caused; the sealing material is sealed with an elastic material. Although the problem of thermal expansion of the seal is solved, the high sealing material has an impact on the production cost. This technology is based on absorbing ...
