Spiral conveyor capable of automatically adjusting distance between blades and shell

Abstract

The invention relates to a spiral conveyor capable of automatically adjusting the distance between blades and a shell. The spiral conveyor comprises a head machine base, a head shell, a feeding port, a cover plate, an upper shell, a hydraulic locking device, first angle steel, a lower shell, supporting legs, second angle steel, the spiral blades, a tail shell, a discharging port, a speed monitoring sensor, a transmission device, sealing filler and rib plates. The spiral conveyor has the beneficial effects that the device can automatically adjust the distance between the blades and the shell of the spiral conveyor according to the particle sizes of materials, the fault problems that the spiral conveyor is blocked and the rotation of the blades is blocked due to the fact that the particle sizes of the conveyed materials are greatly different can be solved without shutdown, the requirement of the spiral conveyor for the uniformity of the particle size of conveyed materials is lowered, the equipment maintenance frequency is reduced, the production efficiency is improved, and the maintenance cost and the labor intensity of workers are lowered.

Description

technical field [0001] The invention relates to the technical field of conveying equipment, in particular to a screw conveyor capable of automatically adjusting the distance between blades and a casing. Background technique [0002] The transportation of materials in industrial production, especially the transportation of powder and small particle materials, has clear requirements for dust flying and environmental pollution. Screw conveyors are widely used due to their simple structure, good sealing performance, no dust in transportation, and convenient operation. However, the existing screw conveyors have the following problems: [0003] 1) The screw conveyor blades and the casing are closely matched, and the requirements for the particle size of the conveyed materials are relatively strict. During production, large-sized, abnormally shaped lumps or hard foreign matter are often mixed into the materials, resulting in the obstruction of the rotation of the screw blades. If...

AI Technical Summary

Problems solved by technology

[0003] 1) The screw conveyor blades and the casing are closely matched, and the requirements for the particle size of the conveyed materials are relatively strict. During production, large-sized, abnormally shaped lumps or hard foreign matter are often mixed into the materials, resulting in the obstruction of the rotation of the screw blades. If there is a jamming phenomenon, it will seriously cause deformation and tearing of the spiral piece, and even motor burnout and other failures, which not only affect production, but also reduce the service life of the equipment;

[0004] 2) Once a fault occurs, it needs to be shut down for inspection during troubleshooting and processing, and more maintenance time is required to disassemble the screw conveyor, which not only increases labor costs, but also reduces production efficiency
