Control system and method of bucket elevator and bucket elevator

Abstract

The invention provides a control system and method of a bucket elevator and the bucket elevator. The system comprises a flow detection device and a control device, wherein the flow detection device isarranged on a motor main loop of the bucket elevator and used for monitoring the running current of the bucket elevator; and the control device is used for controlling the bucket elevator according to the running current. According to the control system and method of the bucket elevator and the bucket elevator, the whole running process of the bucket elevator can be effectively monitored, the situation that an existing bucket elevator fails to shut down when overloaded due to material blockage, and consequently the faults of damage to a hopper and a chain plate of the bucket elevator, tail wheel groove skip and the like are caused can be avoided, and the running safety of the bucket elevator is improved.

Description

technical field [0001] The invention relates to the technical field of aluminum electrolysis anode assembly, in particular to a bucket elevator control system, the system and the bucket elevator. Background technique [0002] The electrolyte broken material return system is used in the aluminum electrolysis anode assembly workshop. The original design mainly has the following problems: the electrolyte slag transported by the bucket elevator often contains flat strips of aluminum and long strips of iron sundries wrapped by the solidification of the electrolyte, and these sundries enter the feed port of the bucket elevator Finally, it gets stuck between the feed inlet and the hopper, often causing the hopper, the plate chain to be jammed, pulled, deformed, or even the plate chain to break and other bucket elevator failures, thereby reducing the safety of the bucket elevator operation. [0003] In view of the above problems, bucket elevators generally have an overload protecti...

Problems solved by technology

The original design mainly has the following problems: the electrolyte slag transported by the bucket elevator often contains flat strips of aluminum and long strips of iron sundries wrapped by the solidification of the electrolyte, and these sundries enter the feed port of the bucket elevator Finally, it gets stuck between the feed inlet and the hopper, often causing the hopper, the plate chain to be jammed, pulled, deformed, or even the plate chain to break and other bucket elevator failures, thereby reducing the safety of the bucket elevator operation

[0003] In view of the above problems, bucket elevators generally have an overload protection function. However, the current overload protection process takes a certain amount of time (according to actual observation and statistics, the electrolyte bucket elevator is blocked by materials and overloaded. The average time for the thermal relay to respond is 25 seconds), during this period of time, the bucket elevator is still continuously overloaded, causing the jammed hopper and plate chain to be pulled and deformed, and even cause the plate chain to break, which is prone to danger. Therefore, it is still impossible to ensure that the bucket elevator security of operation
