Structural characteristics of laboratory rotary furnace

The structural characteristics of laboratory rotary furnaces are mainly reflected in the following aspects:
1. Overall structure and design
Furnace body design: The furnace body of a laboratory rotary furnace is usually a cylindrical structure made of high-quality steel, with a refractory material layer embedded inside to withstand high temperatures and protect the furnace body. The furnace body is horizontally supported on a support and has a certain inclination (such as 3%~6%) to facilitate the movement of materials inside the furnace.
Compact and aesthetically pleasing: The furnace body design is compact, with a simple and elegant appearance, which not only facilitates experimental operation but also improves the overall aesthetics of the equipment.
2. Heating and temperature control system
Heating elements: The heating elements of laboratory rotary furnaces are mostly made of high-quality silicon molybdenum rods and other high-temperature materials, arranged around the furnace to ensure temperature uniformity.
Temperature control method: PID intelligent control system is adopted, which has temperature compensation and temperature correction functions, and can achieve precise temperature control. At the same time, it supports manual/automatic interference free switching function and has over temperature alarm function to ensure experimental safety.
3. Transmission and rotating mechanism
Transmission device: The transmission device of the laboratory rotary furnace is usually driven by an electric motor, which drives the furnace body to rotate through transmission methods such as gears or belts. The transmission device is designed reasonably to ensure the stability and reliability of the furnace body during rotation.
Rotation speed control: By adjusting the motor speed through a frequency converter, the rotation speed of the furnace body can be flexibly controlled to meet different experimental requirements.
4. Sealing and atmosphere control
Sealing measures: The laboratory rotary furnace has good sealing performance, which can ensure the stability and purity of the atmosphere inside the furnace. The furnace door adopts special design, such as bottom lifting furnace door, quick installation flange opening structure, etc., which is easy to operate and has good sealing effect.
Atmosphere control: The equipment is equipped with two air inlet devices, which can switch and charge different gases to meet different sintering process requirements. At the same time, the equipment is also equipped with vacuum pumps and composite vacuum gauges to ensure the required vacuum level inside the furnace.
5. Security protection design
Safety protection: The laboratory rotary furnace has various safety protection designs, such as door opening power-off protection, ultra-high temperature alarm, thermocouple damage power-off, etc., to ensure the safety of the experimental process.
Cooling system: The equipment adopts efficient cooling technologies such as semi open cooling, which can quickly reduce the furnace temperature, shorten the cooling time, and improve experimental efficiency.
In summary, the laboratory rotary furnace has the structural characteristics of compact structure, uniform heating, precise temperature control, stable transmission, good sealing, controllable atmosphere, and comprehensive safety protection. These characteristics have led to the widespread application of laboratory rotary furnaces in research fields such as materials science and chemical engineering.
