Spiral conveyer fault automatic repair device and method

Abstract

Disclosed are a spiral conveyer fault automatic repair device and a spiral conveyer fault automatic repair method. The spiral conveyer fault automatic repair device comprises a first pneumatic gate arranged on a feeding side of a hanging bearing of a spiral conveyer and a second pneumatic gate arranged on a feeding side of a discharging port of the spiral conveyer, and further comprises a PLC (programmable logic controller) control module, a current transformer and a current transmitter which are arranged in a control cabinet, wherein a drive motor of the spiral conveyer is connected with thecurrent transformer, the current transformer is connected with the current transmitter, the current transmitter is connected with the PLC control module, and the PLC control module is respectively connected with the drive motor, the first pneumatic gate, the second pneumatic gate and a material blockage alarm. The spiral conveyer fault automatic repair device and the spiral conveyer fault automatic repair method perform real-time monitoring feedback and automatic judgment on a material blockage problem of the spiral conveyer, and performs repair. The spiral conveyer fault automatic repair device and the spiral conveyer fault automatic repair method solve the technical problems that a material blockage situation cannot be timely discovered, and needs field personnel to shut down the spiralconveyer and open the spiral conveyer for drawing and digging blocked materials even if discovered in the prior art.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis of screw conveyors, in particular to an automatic fault repairing device and method for screw conveyors. Background technique [0002] The screw conveyor is divided into U-shaped screw conveyor and tubular screw conveyor in appearance. The working principle of the screw conveyor is that the rotating screw blade pushes the material for screw conveying. The force that keeps the material from rotating with the screw conveyor blades is the weight of the material itself and the frictional resistance of the screw conveyor casing to the material. The spiral blade is welded on the rotating shaft of the screw conveyor. The surface type of the blade has solid surface type, belt type surface type, blade surface type and other types according to the different materials to be conveyed. The screw shaft of the screw conveyor is provided with a thrust bearing at the end of the material moving direction ...
