Technical Field
[0001] The utility model belongs to the technical field related to rotary kilns, in particular to a connection structure of a furnace tube of an ultra-high temperature rotary kiln. Background Art
[0002] In industrial production, especially in the chemical and metallurgical industries, equipment that can withstand ultra-high temperatures is often needed. As a widely used heat treatment equipment, the performance of the rotary kiln directly affects production efficiency and product quality. Traditional rotary kiln tubes are mostly made of a single material and cannot withstand ultra-high temperature environments for a long time. They are also prone to deformation at high temperatures, which affects their service life and safety.
[0003] The rotary kilns in the existing technology are mostly made of metal furnace tubes. When the furnace tubes are long, the connection between the furnace tubes is mostly made by welding. The furnace tubes connected by welding cannot withstand ultra-high temperatures. Therefore, it is necessary to develop a connection structure for the furnace tubes of an ultra-high temperature rotary kiln to solve the above technical problems. Utility Model Content
[0004] In view of the above problems, the utility model provides a connection structure of a furnace tube of an ultra-high temperature rotary kiln, which is used to solve the technical problem of unstable connection of furnace tubes in the prior art.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A connection structure of a furnace tube of an ultra-high temperature rotary kiln, wherein the furnace tube is assembled from multiple sections, one section of which is composed of a first furnace tube and a second furnace tube, a clamp is provided at the connection between the first furnace tube and the second furnace tube, and a pin is provided between the first furnace tube, the second furnace tube and the clamp; the furnace tube and the clamp are both made of carbon fiber material.
[0007] As a further improvement of the above solution, the first furnace tube and the second furnace tube are connected via a stopper.
[0008] As a further improvement of the above solution, a gap is provided at the stop.
