Abstract
The invention discloses an electrothermal hot air drying furnace which mainly comprises a left drying chamber, a heat exchange chamber, a right drying chamber, an electric heater and a hot air circulating fan, wherein the left drying chamber and the right drying chamber are arranged on two sides of the heat exchange chamber; a hot air circulating channel is formed by the left drying chamber and the heat exchange chamber; a hot air circulating channel is formed by the right drying chamber and the heat exchange chamber; the hot air circulating fan is arranged at the top of the heat exchange chamber; the electric heater is arranged in the heat exchange chamber; the hot air circulating fan pushes hot air to downwards move; after being heated by the electric heater, the hot air enters the left drying chamber and the right drying chamber; after upwardly penetrating through a dried material in the left drying chamber and the right drying chamber, the hot air backflows to the heat exchange chamber respectively through a left air guide pipe and a right air guide pipe. By adoption of a dual-circulating heating mode, the utilization rate of heat energy is greatly increased; by additional arrangement of an air volume adjustment plate, a fresh air inlet and a steam exhaust pipe can be simultaneously opened or closed, so that the operation for replacing air and steam is greatly facilitated.

The left side wall of described heat-exchanging chamber and the bottom of right side wall have the downward-sloping through hole that the left drying chamber of multiple difference is communicated with right drying chamber.
Described left wireway and right wireway are connected with steam comb.
On described left wireway and right wireway and the side being positioned at steam comb has new wind entrance, described new wind porch is provided with air-flow plate, and the lower port of new wind entrance and steam comb is opened simultaneously or closes simultaneously by described air-flow plate.
Materials vehicle is provided with in described left drying chamber or right drying chamber.
Multiple permeability type material frame distributed from down to up is provided with in described left drying chamber or right drying chamber.
Beneficial effect of the present invention: owing to have employed bicirculating heat form, substantially increase the utilization rate of heat energy; By having set up air-flow plate, can open or close new wind entrance and steam comb simultaneously, greatly facilitating the operation of ventilation and steam.
