Straw drying device utilizing induction heating and provided with double heating structures

Abstract

The invention discloses a straw drying device utilizing induction heating and provided with double heating structures. The straw drying device comprises a conveying belt mechanism, the conveying belt mechanism is driven by a servo motor fixedly installed on the side wall of the right end of the conveying belt mechanism, and first supporting frames are fixedly installed on the lower surfaces of the two ends of the conveying belt mechanism correspondingly. A protective cover is arranged on the outer side of the middle position of the conveying belt mechanism, two fans are evenly and fixedly installed on the top of the protective cover in the length direction of the conveying belt mechanism, filter screens are fixedly installed on the upper surfaces of the two fans, and a control switch is fixedly installed at the upper left end of the front face of the protective cover. A water tank opening is formed in the lower end of the front face of the protective cover, and a low-frequency power source is electrically connected with an induction hollow copper pipe coil fixedly arranged in the protective cover in the length direction of the conveying belt mechanism. The induction heating mode is adopted, the heating speed is high, the temperature is high, dual heating structures are adopted, and rapid drying and heating of straw can be achieved.

Description

technical field [0001] The invention relates to the technical field of straw recovery, in particular to a straw drying device with a dual heating structure using induction heating. Background technique [0002] Straw is the general term for the stem and leaf parts of mature crops. In order to avoid air pollution caused by straw burning, it is a better way to deal with straws by baling and bundling straws for centralized transportation and recycling. Straw needs to be dried before recycling. [0003] Existing straw drying devices generally adopt air drying or heating plate drying methods, and the air drying drying method has a lower temperature, so the drying speed of straw is slower and the drying effect is not thorough enough; while the heating plate drying method The method is limited by the slow temperature rise of the heating plate, and the heating plate can only heat and dry the straw from one side (such as the bottom), which leads to low drying efficiency.

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a straw drying device with a double heating structure using induction heating to solve the problem that the existing straw drying device proposed in the background technology generally adopts the drying method of air drying or heating plate, wherein the air drying The temperature of the drying method is low, so the drying speed of the straw is relatively slow, and the drying effect is not thorough enough; while the heating plate drying method is limited by the slow temperature rise of the heating plate, and the heating plate can only be heated from One side (such as the bottom) heats and dries the straw, which leads to the problem of low drying efficiency
