Electromagnetic induction heating rotary kiln

Abstract

The invention relates to an electromagnetic induction heating rotary kiln which can particularly improve heating speed and heating efficiency, and is efficient and energy-saving. Different from a traditional heating method, the electromagnetic induction heating enables the rotary kiln to heat by oneself without naked light, is high in heating speed, short in preheat time, and capable of accurately controlling operating temperature of the rotary kiln. The operating temperature is 80-1100 DEG C, and operating frequency is 10KHz-40KHz, the heating efficiency is high and is more than or equal to 85%-99%. A device is light, size is small, production manufacture cost of the device is low, and using cost of the device is low. Effective operating period time of the device is long, and unit time handling capacity and production efficiency of the device are high. The electromagnetic induction heating rotary kiln has an automatic kiln cleaning function, and is suitable for scrap lead smelting, waste zinc smelting, waste aluminum smelting, mineral product drying and roasting, building material drying and roasting, chemical product drying and roasting, traditional Chinese medicinal material dewatering and drying, agricultural product dewatering and drying and farm fertilizer (chicken manure and pig manure and cow manure and the like) dewatering and drying and disinfecting.

Description

Technical field [0001] The invention relates to an electromagnetic induction heating rotary kiln, in particular, it can improve the heating speed and thermal efficiency of the rotary kiln, and is highly efficient and energy-saving. Different from traditional heating methods, electromagnetic induction heating makes the rotary kiln self-heating, without open flame, fast heating speed and short preheating time. It can precisely control the working temperature of the rotary kiln, working temperature: 0℃~1100℃, working frequency: 10KHz~40KHz, high thermal efficiency, thermal efficiency: ≥85%~99%. The equipment is light, small in size, low in equipment manufacturing cost, low in equipment use cost, long in effective working cycle, high in processing capacity per unit time and high in production efficiency. With the function of automatic kiln cleaning, the cleaning speed is fast, the time is short and the efficiency is high. During the production process, no waste gas such as smoke...
