Electric heating type U-shaped hot material heat preservation conveying groove and spiral heat preservation conveyor for transferring hot materials

Abstract

The invention discloses an electric heating type U-shaped hot material heat preservation conveying groove and a spiral heat preservation conveyor for transferring hot materials. The U-shaped heat preservation conveying groove comprises a U-shaped conveying groove body, an electric heating heat preservation layer, a groove cover component and a groove sealing end plate. According to the innovative scheme, a U-shaped electric heating heat preservation layer is additionally arranged on the periphery of an existing U-shaped conveying groove and comprises an electric heating pipe, a U-shaped heat preservation cover and heat insulation cotton. An existing U-shaped material conveying groove is adaptively improved, the U-shaped material conveying groove is wrapped by the electric heating heat preservation layer, the groove sealing end plates are welded to the two ends of the U-shaped material conveying groove, the material conveying groove is covered with the groove cover, and the electric heating temperature is adjustable; and on-line electric heating continuous heat preservation can be carried out on hot materials in the transfer conveying process in the U-shaped material conveying groove, so that the hot materials do not deform in the transfer process. According to the spiral heat preservation conveyor, the U-shaped heat preservation conveying groove is used, and the technical problems that a U-shaped conveying groove lacks the heating and heat preservation function and cannot meet the requirement of a special spiral conveyor user for heat preservation and transfer of heat transfer materials are solved. The post-drying treatment effect of hot materials is guaranteed; the product is upgraded and updated, and energy and efficiency are increased.

Description

technical field [0001] The invention belongs to the technical field of a shafted screw conveyor for transferring heated materials from a filter press to a dryer, and relates to a U-shaped heat preservation conveying trough for transferring heated materials. Background technique [0002] The screw conveyor is a kind of equipment that uses the motor to drive the screw to rotate and push the material to achieve the purpose of closed conveying; the screw conveyor with a shaft is a screw conveyor with a screw center shaft and a screw blade that does not touch the bottom of the trough; The heat preservation conveyor refers to the shafted screw conveyor for the heat preservation and transfer of hot materials (such as hot filter cakes that need post drying treatment) for heat preservation and transfer, that is, the intermediate process equipment of the filter press and the dryer; mainly by the screw drive device, It is composed of a shaft screw device and a U-shaped feeding chute; i...
