Abstract

The invention discloses a conveyer belt multi-pole magnetic roller asynchronous demagnetizing device, which comprises a multi-pole magnetic roller (1), a magnetic roller drive motor (5), a magnetic roller framework (18), a structural frame (10), a lifting device and a controller (12), wherein the multi-pole magnetic roller is hang on the magnetic roller framework through a magnetic roller shaft, the magnetic roller drive motor drives a magnetic roller shaft transmission belt wheel (2) to rotate through a power belt wheel (4) and a transmission belt (3) so as to drive the multi-pole magnetic roller to rotate, and the multi-pole magnetic roller is positioned above a conveyer belt (6); the structural frame is positioned above a conveyer belt return plane, and a vertical bar of the structural frame is fixed on the ground; and one end of the magnetic roller framework is connected on the vertical bar of the structural frame through a rotating shaft (11), the other end of the magnetic roller framework is provided with the hoisting device, an upper stop point (17) and a lower stop point (1) with travel switches are formed on the vertical bar at the other end of the structural frame, the output of the travel switches is connected with a controller (12), and the controller controls the magnetic roller drive motor and the hoisting device. The demagnetizing device has the advantages of simple structure, low energy consumption and good demagnetizing effect.

Description

technical field [0001] The invention relates to a degaussing device, in particular to an asynchronous degaussing device for multi-pole magnetic rollers of a conveyor belt, which is used for eliminating the magnetized magnetic field of a metal-lined conveyor belt. Background technique [0002] The most taboo of bulk materials (mineral materials) in the process of transportation is to mix metal waste, especially the long rod-shaped sharp metal objects are the most harmful; the consequence is light damage to the machinery and equipment along the conveyor belt In severe cases, the conveyor belt of the conveyor unit will be torn, causing the entire conveyor belt to break and stop production, resulting in huge losses. The metal objects mixed in bulk materials such as coal and ore are basically iron and steel substances. These iron and steel substances are generally mixed in the process of ore collection and transportation. They are machinery and equipment in various links. Parts,...
