Abstract

The invention discloses a molecular sieve tunnel type microwave drying device continuously adjustable in power. The main body of the molecular sieve tunnel type microwave drying device is a microwavedrying furnace, and the molecular sieve tunnel type microwave drying device is provided with a feeding end and a discharging end, and further comprises microwave heating resonant cavities, a materialconveying system, a microwave source, a microwave power adjusting device, a microwave suppression system, a moisture exhaust and cooling system, an electric control system and a temperature measurement system. According to the molecular sieve tunnel type microwave drying device, a microwave device continuously adjustable in power is adopted to uniformly heat molecular sieve materials, and the temperatures of all portions of the molecular sieve materials in tunnel type microwave cavity bodies are measured through an infrared thermometer; if the temperatures are too high or too low, the temperatures of the molecular sieve materials in the microwave cavities are within an appropriate material heating temperature range by adjusting the microwave power; and compared with conventional microwavedrying devices constant in power, the molecular sieve tunnel type microwave drying device continuously adjustable in power has the advantages of being capable of prolonging the service life of a magnetron of the microwave source, low in energy consumption, high in heating efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of drying devices, and more specifically relates to a molecular sieve tunnel microwave drying device with continuously adjustable power. Background technique [0002] Molecular sieves (Molecular sieves) are a class of naturally occurring or synthetic silicate or aluminosilicate crystal materials with regular microporous structures. Because of their uniform pore size and high specific surface area, they have many excellent characteristics. . The drying of molecular sieves takes a long time using the traditional drying method, consumes a lot of power, and heats unevenly. However, the use of microwave drying molecular sieves has the advantages of low energy consumption, high speed, and high efficiency compared with traditional heat conduction drying. [0003] At present, the conventional molecular sieve tunnel microwave drying equipment uses multiple microwave sources to heat the continuous molecular sieve mat...
