Double-side heat exchange tunnel type drying room with built-in heat source

Abstract

The invention discloses a double-side heat exchange tunnel type drying room with a built-in heat source. The double-side heat exchange tunnel type drying room with the built-in heat source comprises a room body, the interior of the room body is divided into a drying chamber and a heating chamber through two partition plates, and a drying frame is arranged in the drying chamber; and a supporting plate is fixed to the lower side wall of the room body, a motor is fixed to the upper side wall of the supporting plate, the driving end of the motor faces upwards and is fixedly provided with an incomplete gear, two rotating rods are installed on the supporting plate, a first gear and a second gear are fixed to each rotating rod, the two second gears are located on one side of the incomplete gear, a sliding plate is slidably inserted into the outer wall of the room body, and the left end of the sliding plate is fixedly connected with the outer wall of the drying frame. According to the double-side heat exchange tunnel type drying room, materials are automatically dried through automatic feeding of a material storage box, full contact between the materials and high-temperature airflow is guaranteed through left-right reciprocating movement of the drying frame, drying blind spots are avoided, a dense net plate automatically rotates downwards, the materials are guided out to a conveying belt to be conveyed and guided out, and automation of drying work is achieved.

Description

technical field [0001] The invention relates to a double-sided heat exchange tunnel drying room with a built-in heat source. Background technique [0002] Tunnel drying room is a device for drying materials by means of alternating heat exchange. [0003] After retrieval, Chinese patent document CN104457189A discloses a double-sided heat exchange tunnel-type drying room with built-in heat source. The outside of the frame is covered with thermal insulation walls. Separated into air heating areas on both sides and material drying areas in the middle, and the upper and lower ends of the heat insulation wall have air ducts connecting the air heating area and material drying area; the bottom of the insulation wall outside the air heating area There is an air inlet, and a combustion furnace and a heat exchanger are arranged in the air heating area, and the air inlet at the upper end of the heat exchanger is connected with the exhaust port at the upper end of the combustion furnace...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned patent documents all involve a tunnel-type drying room. The inside of the drying room drives the material to move progressively through the conveyor belt. Although the material is in a moving state, the material is in a piled state, and there are blind spots in contact with the hot air flow, which cannot guarantee sufficient drying.
