Drying apparatus based on peristaltic propelling

A drying apparatus based on peristaltic propelling, comprising:

• a heat supply module;
• a drying chamber;
• and
• a conveying device;
• wherein the conveying device is arranged in the drying chamber;
• the drying chamber is provided with a heat source inlet, a heat source outlet, a feeding port and a discharging port;
• a heat output point of the heat supply module is arranged at the heat source inlet and is configured to provide a heat source for the drying chamber;
• the conveying device is configured to provide a platform for laying and propelling a material to be dried;
• and
• the platform of the conveying device is formed by laying a plurality of main parts capable of generating relative local movement and displacement;
• a gap is provided between adjacent two main parts to allow air to pass through;
• and the plurality of main parts are configured to repeatedly flip the material to be dried to enable peristaltic propelling of the material to be dried and keep the gap unobstructed;
• wherein each of the plurality of main parts comprises a conveying sub-platform;
• the conveying sub-platform is formed through alternate stacking of at least two groups of first grids;
• two adjacent first grids in the same group are separated by a gasket;
• and a thickness of the gasket is greater than that of first grids in another group of the at least two groups of first grids to form the gap;
• the at least two groups of first grids comprise at least one movable grid group, and the at least one movable grid group is capable of generating relative displacement with respect to another group of the at least two grid groups, so as to enable the at least one movable grid group to reciprocate;
• and
• each movable grid of each of the at least one movable grid group is provided with at least two connecting holes respectively at front and rear balance positions;
• movable grids of each of the at least one movable grid group are connected to form a moving body through a connecting rod penetratedly arranged in the connecting holes;
• and the moving body is configured to guide and drive all movable grids of a corresponding movable grid group to move in the same trajectory through a drive device.
