A double-sided heat exchange tunnel drying room with built-in heat source

Abstract

The invention discloses a double-sided heat exchange tunnel drying room with a built-in heat source, which includes a room body, and the inside of the room body is divided into a drying room and a heating room by two partitions. Dry frame; the lower side wall of the house body is fixed with a support plate, the upper side wall of the support plate is fixed with a motor, the driving end of the motor is upward and an incomplete gear is fixed, and two gears are installed on the support plate. Two rotating rods, gear 1 and gear 2 are fixed on the two rotating rods, the two gears are located on the side of the incomplete gear and meshed with the incomplete gear, slidingly inserted on the outer wall of the housing body There is a slide plate, and the left end of the slide plate is fixedly connected with the outer wall of the drying frame. The invention realizes the automatic drying of the material through the automatic feeding of the material storage box, and the left and right reciprocating movement of the drying frame ensures the full contact between the material and the high-temperature airflow, avoids drying blind spots, and makes the dense mesh plate automatically turn down to export the material to the conveyor belt Transport and export on the machine to realize the automation of drying work.

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.
