Energy-saving circulating granary dryer based on electric heating

Abstract

The invention discloses an energy-saving circulating granary dryer based on electric heating. The dryer comprises a heating box and heating plates, the plurality of heating plates are installed on theupper surface and the lower surface of the inner wall of the heating box, an air inlet and an air outlet are formed in the surface of the heating box, a connecting device is arranged on the left sideof the heating box, the connecting device is fixedly connected with the air inlet, a fan is fixedly connected to the left side of the connecting device, an air exchange opening is formed in the top of the heating box, air outlet valves are installed in the air exchange opening and the air outlet, the connecting device comprises a connecting pipeline, a drying layer, an air inlet valve and a humidity sensor, the connecting pipeline is installed on the left side of the air inlet, and one end, far away from the air outlet, of the connecting pipeline is fixedly connected with the fan. According to the energy-saving circulating granary dryer based on electric heating, the heating plates are electrified and heated, cost is saved, and the energy-saving circulating granary dryer is economical, environmentally friendly, simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the technical field of granary drying equipment, in particular to an energy-saving circulation granary dryer based on electric heating. Background technique [0002] The granary dryer is used for the drying of grain reserves to prevent the grain from getting damp and moldy. With the improvement of grain varieties, the increase of per unit yield and the increase of the country's investment in grain drying equipment, the construction of large, medium and small grain drying facilities more and more. It is very important to choose a dryer with high quality, long service life, economical and practical, good reliability and high degree of automation. [0003] According to the existing patent CN209893852U, an energy-saving circulating granary dryer includes a shell, an inner bin, a suction pipe, a suction branch pipe, a first screw fan, a heating furnace, a dust suction duct, a second screw fan, Bucket elevator, feed pipe, vibrating...

Problems solved by technology

[0003] According to the existing patent CN209893852U, an energy-saving circulating granary dryer includes a shell, an inner bin, a suction pipe, a suction branch pipe, a first screw fan, a heating furnace, a dust suction duct, a second screw fan, Bucket elevator, feed pipe, vibrating screen, conveyor belt, discharge and circulation mechanism, and circulation discharge pipe. An inner warehouse is installed inside the outer shell, and a suction pipe is interspersed inside the inner warehouse. This energy-saving circulation type granary oven The drying machine uses a heating furnace. Most of the existing kerosene heating furnaces are used in the market. For small and medium-sized enterprises, it cannot save costs and is not environmentally friendly. Therefore, we propose an energy-saving system based on electric heating. Circulating Granary Dryer
