Embodiment Construction

[0010] Referring to the accompanying drawings, the furnace body has a rotating and sealing structure at high temperature. On the contact surface 1 of the furnace body, there are two hard packing 2 and flexible packing 3. A pressure ring 4 is engaged on the flexible packing 3. Both sides of the pressure ring 4 are connected to the The hard packing 2 is slidingly fitted, and the two hard packing 2 are respectively pressed with a sealing cover retaining ring 5 and a sealing cover 6. The sealing cover 6 is fixedly connected with an L-shaped support plate 7, and the upper end of the support plate 7 is fixedly connected with a The upper guide rod 8, the upper guide rod 8 is slidingly matched with the lower guide rod 9, the lower end of the lower guide rod 9 passes through the sealing cover 6, the lower end of the lower guide rod is pressed on the pressure ring 4, and the upper guide rod 8 is screwed with an adjusting nut 10. The lower guide rod has a step, a spring 11 is pressed betw...

Abstract

The invention discloses a furnace body high-temperature-state rotating sealing structure. Two hard packings and a flexible packing are arranged on a contact face of a furnace body, a pressing ring is buckled on the flexible packing, two sides of the pressing ring are in sliding fit with the hard packings, the hard packings are provided with a sealing cover retaining ring and a sealing cover in a pressed manner respectively, an L-shaped supporting plate is fixedly connected on the sealing cover, an upper guide rod is fixedly connected at the upper end of the supporting plate and slidably matched with a lower guide rod, the lower end of the lower guide rail penetrates the sealing cover, the lower end of the lower guide rod is arranged on the pressing ring in a pressed manner, an adjusting nut is screwed on the upper guide rod, the lower guide rod is provided with a step, and a spring is mounted between the adjusting nut and the step in a pressed manner. By adopting a flexible sealing structure, the furnace body high-temperature-state rotating sealing structure is adjustable in sealability and simple and reliable in structural design, and using performance of equipment is greatly improved.

Description

technical field [0001] The invention relates to a rotary sealing structure of a furnace body in high temperature state. Background technique [0002] Because the traditional rubber sealing ring can only play a sealing role within the elastic limit, it is also a contact seal, which also has wear problems, and is not suitable for use in high temperature occasions. Therefore, an alternative material with the same effect must be found. Because of the lower pressure, we determined that the main role of the alternative material is high temperature resistance and better flexibility. In daily static mechanical seals, we often apply a layer of grease on the surface of sealing materials such as asbestos to enhance the sealing effect, and tungsten disulfide high-temperature greases on the market have products with a service temperature of 600-800 °C. Contents of the invention [0003] The purpose of the present invention is to provide a rotating sealing structure of the furnace bod...
