Anti-jamming method for bucket elevator

Abstract

The invention discloses an anti-jamming method for a bucket elevator. A variable frequency motor is adopted to replace a traditional motor, the variable frequency power can be automatically adjusted according to the change of the feeding amount, optimal parameters are set after multiple times of adjustment, the purposes of energy conservation and speed regulation are achieved, and the energy consumption is greatly reduced; the motor is arranged outside a lower shell, so that maintenance personnel can conveniently carry out maintenance, the risk of high-altitude operation is avoided, and the maintenance difficulty is reduced; the groove wall of the lower shell is designed to be arc-shaped, a discharging mechanism is arranged, materials scattered by a hopper in the transportation process aredischarged out of the lower shell along with a flow guide groove, so that the motor damage caused by material jamming and overload is avoided, and the service life of the motor is prolonged; a vibration device can vibrate off the materials attached to the groove wall, so that the materials are prevented from blocking a discharging hole; and a worker can wash and air-dry an inner cavity of the bucket elevator, and the sewage after washing can be discharged through the discharging mechanism, so that the method is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of material transportation, in particular to a method for preventing jamming of a bucket elevator. Background technique [0002] The hoist is a kind of vertical lifting equipment, which is widely used, mainly including ore, coal, cement and cement clinker, grain, chemical fertilizer and other materials. Among them, the plate chain hoist has the advantages of large lifting height, wide range, and small driving power. advantage. It is especially suitable for the transportation and lifting of various powders. [0003] During the process of transporting materials, the bucket elevator is suitable for lifting from low to high. After the supply material is put into the hopper through the vibrating table, the machine will automatically and continuously run upwards, and the transmission speed can be adjusted according to the transmission volume, and can be selected on demand. Lifting height, the hopper is designed ...

AI Technical Summary

Problems solved by technology

However, the flow rate of the feed hopper of the existing bucket elevator is fixed, and the size cannot be adjusted. During use, the bottom of the bucket elevator is often blocked due to excessive flow, which reduces the practicability of the bucket elevator.

At the same time, material jamming and overloading will cause damage to the motor. The motor in the existing hoist is generally installed at a high place, requiring maintenance personnel to work at high altitudes, which increases the difficulty of maintenance and increases the risk of maintenance
