Drying system for continuous circulated operation

Abstract

The invention discloses a drying system for continuous circulated operation. The drying system comprises a drying unit, a feeding unit, a discharge unit, an air inlet unit and a lifting unit, wherein the drying unit comprises a shell with a heat-preservation layer outside, a plurality of discs which are matched with the inner side wall of the shell to accommodate a material to be dried, and a first conveying unit for displacing the discs of the material to be dried in a preset direction in a stepping manner so as to dry the material at preset time intervals; the lifting unit is arranged on the other side outside the shell and is communicated with the interior of the shell through a second conveying unit and a third conveying unit which are connected with one side of each of the bottom and the top of the shell respectively, thus achieving circulated conveying of empty discs. Due to cooperation of the units, a plurality of drying areas are formed by virtue of different temperatures and pressures inside the shell, and furthermore continuous utilization of heat is achieved, so that the drying system for continuous circulated operation, which is disclosed by the invention, has the effects of good implementation effect, high production efficiency, high heat utilization and high safety.

Description

technical field [0001] The invention relates to a multi-layer drying device used in the case of drying materials. More specifically, the present invention relates to a drying system capable of continuous cycle operation for use in the case of drying granular materials by utilizing hot air. Background technique [0002] The full English name of drying equipment is Drying equipment, which refers to the combination of a series of mechanical equipment that dries the moisture on the surface of objects or other liquids through certain technical means. The current popular drying technologies are mainly ultraviolet drying and infrared drying. Electromagnetic drying and hot air drying have their own characteristics and are widely used in the drying of various mechanical equipment and food. [0003] At present, the existing multi-layer dryers used for granular materials are usually composed of a shell, an insulation layer, a drying chamber, a door, an air inlet, an exhaust port, a gr...

AI Technical Summary

Problems solved by technology

[0004] However, when the existing drying equipment adopts multi-layer drying for granular materials, there are mainly the following problems: one is that when a plurality of trays are arranged in the housing, most of them are plugged in, and then the During the plugging process, the internal heat is easily lost, and at the same time, a large amount of hot air will gushes out during the plugging process, which is likely to cause damage to external equipment and the human body; The continuous cycle operation cannot be realized in the drying process, resulting in low thermal efficiency utilization and low drying efficiency
