Efficient drying machine

Abstract

The invention discloses an efficient drying machine. The efficient drying machine comprises a base plate; a fan is arranged on the base plate; an air outlet of the fan communicates with a first connecting pipe; the end, far away from the fan, of the first connecting pipe communicates with a heating box; the heating box is internally provided with an electric heating pipe; the side edge of the heating box communicates with second connecting pipes; the ends, far away from the heating box, of the second connecting pipes communicate with a drying box; a first motor is arranged at the bottom of the drying box; an output shaft of the first motor is connected with a stirring shaft; the side edges of the stirring shaft are fixedly provided with stirring blades; the side edge of the drying box communicates with a discharging channel and third connecting pipes; the top of the drying box communicates with a feeding channel; the end, far away from the drying box, of the feeding channel communicates with a preheating box; and a metal net disc is arranged in the preheating box and is of a cuboid structure. The efficient drying machine has the advantages that pre-drying of materials in the preheating box and deep drying of materials in the drying box can be carried out at the same time, and therefore the material drying efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of dryers, in particular to a high-efficiency dryer. Background technique [0002] A dryer is a mechanical device that uses thermal energy to reduce the moisture content of materials and is used to dry objects. The dryer vaporizes and escapes the moisture in the material (generally refers to water or other volatile liquid components) by heating to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. [0003] The Chinese patent of authorized notification number CN 205967636 U discloses a high-efficiency dryer, which includes a drying box body, and the drying box body includes a first box body, a second box body, a third box body, a material inlet and an outlet. Material inlet, the top left side of the first box is provided with a feed inlet; the middle of the first box is provided with a rotating shaft; the bottom of the...

Problems solved by technology

This patent can achieve stirring of materials and has a good drying effect, but in this patent, the hot air in the drying tank is directly discharged, which is not well utilized, and the energy utilization efficiency is very low. Heating at the initial temperature consumes a very long time and the work efficiency is very low
