Conveying device inside microwave resonance cavity

Abstract

The invention discloses a conveying device inside a microwave resonance cavity. The conveying device inside the microwave resonance cavity comprises a ceramic roller stick (1) and a conveying belt for microwaves, wherein the ceramic roller stick (1) is provided with metal spindle heads, the conveying belt is arranged above the ceramic roller stick (1), the metal spindle heads at two ends of the ceramic roller stick (1) are arranged on bearing bases (3) through metal bearings (2), and two ends, at the positions of opening holes in the microwave resonance cavity, of the ceramic roller stick (1) are respectively provided with a shielding base (4) with absorbing loads, a compression wire gasket (5), a shielding gland (6) and a shielding sleeve (7). According to the conveying device inside the microwave resonance cavity, the ceramic roller stick is used as a supporting device and a rolling device of the conveying belt, friction force can be lower, the abrasion of the conveying belt is reduced, working efficiency is improved, stable supporting acting force can be supplied, materials are prevented from being thrown and falling, especially due to the fact that the shielding bases, the compression wire gaskets, the shielding glands and the shielding sleeves with absorbing loads are arranged at the two ends, the microwaves are effectively prevented form leaking from the opening holes at two ends of the microwave resonance cavity, safety is ensured, and a plurality of defects in the prior art are overcome.

Description

technical field [0001] The invention relates to a matching device of microwave heating equipment, in particular to a device for conveying materials in a microwave resonant cavity. Background technique [0002] Microwave heating uses microwaves as an energy source. When microwaves interact with material molecules, molecular polarization, friction, collision, and absorption of microwave energy generate thermal effects. This heating method is called microwave heating. The microwave heating method is superior to the traditional steam heating, electric heating, and infrared heating methods. It has the advantages of high efficiency, uniform heating, easy control, easy automation, small equipment size, good product quality, disinfection, sterilization, and product safety and hygiene. Microwave energy generators have been widely used in industrial processing and production, such as dehydration and desulfurization of coal. The conveying equipment must be used when the material is tr...

AI Technical Summary

Problems solved by technology

The conveying device in the prior art generally directly uses a rubber conveyor belt driven by a motor, which has poor load-bearing performance, and is caused by sliding friction. The transmission device has an unreasonable structural design, and there is often a certain amount of leakage in the microwave, which has a relatively large adverse effect on the operator's body, which greatly limits its popularization and application.
