Aluminum oxide belt conveying system and method

Abstract

The invention discloses an aluminum oxide belt conveying system. The aluminum oxide belt conveying system comprises a controller, a belt conveyor, a material beating indication lamp, a roller detection switch, a conveying belt off-tracking treatment device, a pull rope switch and a door limiter switch, wherein the belt conveyor, the material beating indication lamp, the roller detection switch, the conveying belt off-tracking treatment device, the pull rope switch and the door limiter switch are connected with the controller. The material beating indication lamp is mounted on an aluminum oxidewarehouse material beating platform. The roller detection switch is arranged on a roller bearing seat and matched with the outer diameter of a roller. The conveying belt off-tracking treatment deviceand the pull rope switch are arranged in the conveying direction of the belt conveyor. The door limiter switch is arranged at an inlet of a maintenance platform of the belt conveyor. When the belt conveyor operates normally, if the controller receives one or more of a shaft rupture signal of the roller detection switch, an off-tracking signal of the conveying belt off-tracking treatment device, an actuating signal of the pull rope switch and a door closing signal of the door limiter switch, the belt conveyor is controlled to stop and the material beating indication lamp is controlled to be off, so that the site emergency stop occurring when an accident is caused is achieved; and the aluminum oxide belt conveying system is high in automation degree and safety. The invention further discloses an aluminum oxide belt conveying method.

Description

technical field [0001] The invention relates to the technical field of alumina transport, in particular to a device and a transport method for transporting alumina by using a belt conveyor in an electrolysis plant area. Background technique [0002] In the existing electrolysis plants, dense-phase or dilute-phase transportation is generally adopted for the transportation of alumina, but dense-phase or dilute-phase transportation will cause relatively large damage to alumina, which affects electrolytic production and flue gas purification; transportation The pipe is easy to wear through the hole, and the maintenance amount is large; and the conveying capacity is small, and the equipment investment is high. Another existing way is to apply the belt conveyor to the aluminum electrolysis plant to transport the electrolytic raw material alumina, but the belt conveyor should be used in this field for a short time, and many problems in operation have not been solved in time, for ex...

Problems solved by technology

[0002] In the existing electrolysis plants, dense-phase or dilute-phase transportation is generally adopted for the transportation of alumina, but dense-phase or dilute-phase transportation will cause relatively large damage to alumina, which affects electrolytic production and flue gas purification; transportation The pipe is easy to wear and tear through the hole, and the maintenance amount is relatively large; and the conveying capacity is small, and the investment in equipment is high

Another existing way is to apply the belt conveyor to the aluminum electrolysis plant to transport the electrolytic raw material alumina, but the belt conveyor should be used in this field for a short time, and many problems in operation have not been solved in time, for example, when In the event of equipment failure or / and personal safety accidents, it cannot be shut down in time, resulting in the continuous feeding of the equipment and the occurrence of aluminum oxide leakage, which also results in a long time for troubleshooting; moreover, the existing belt conveyor is not highly automated, and still It requires a lot of manual cooperation, a large amount of manual labor, and low work efficiency
