High-temperature rotary furnace with dual-layer sleeve structure

Abstract

The invention discloses a high-temperature rotary furnace with a dual-layer sleeve structure. The high-temperature rotary furnace comprises a base. A rotary furnace body is installed at the top end ofthe base. A rotating cylinder is sleeved with the rotary furnace body. A feeding pipe is embedded in one side of the rotating cylinder. A discharging pipe is embedded in the other side of the rotating cylinder. A heating coupler is installed at the bottom end of the rotary furnace body. A filtering mechanism is installed at the top end of the rotary furnace body. In the high-temperature rotary furnace, by rotating the rotating cylinder, materials can be more evenly and rapidly heated; harmful gas in the rotary furnace body can be sucked into a gas collecting box through an electric fan in a ventilating pipe, harmful impurities in the gas can be filtered out by a carbon fiber filter screen in the gas collecting box, and the carbon fiber filter screen can be pulled out of the gas collectingbox through sliders by pulling a handle so as to be conveniently replaced; and the too high pressure in continuous heating of the rotary furnace body can be relieved through the electric fan, and thefurnace blasting condition is avoided.

Description

technical field [0001] The invention belongs to the technical field of rotary furnaces, and in particular relates to a high-temperature rotary furnace with a double-layer casing structure. Background technique [0002] The furnace body of the rotary furnace is a long steel cylinder lined with refractory materials. The furnace body is supported on several pairs of supporting wheels and has a gradient of 3% to 6%. The furnace body is slowly rotated by the motor through the gear, and the material is added from the higher tail end and discharged from the lower furnace head end. [0003] There are following problems in prior art: [0004] 1. The existing high-temperature rotary furnace has slow heating efficiency during its use, and the heating of materials is not uniform enough; [0005] 2. When the existing high-temperature rotary kiln is in use, the exhaust gas generated by the internal materials or the harmful gas generated by special materials are directly discharged when ...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing high-temperature rotary furnace has slow heating efficiency during its use, and the heating of materials is not uniform enough;

[0005] 2. Existing high-temperature rotary kiln, when it is in use, waste gas generated by internal materials or harmful gas generated by special materials is directly discharged when it is heated, causing certain pollution to the environment

[0006] 3. In the existing high-temperature rotary furnace, when it is in use, the device will generate large vibrations when it is heated and rotated. Long-term vibration will cause loose parts of the device and make relatively loud noises
