Three-rail six-winch calcium carbide furnace tapping control system and control method thereof

Abstract

The invention provides a three-rail six-winch calcium carbide furnace tapping control system. The system comprises a three-outlet calcium carbide furnace; winches, each two of which, as a group, are arranged at each outlet of the calcium carbide furnace; on-site control boxes which are arranged at the adjacent position of each winch set at each outlet position of the calcium carbide furnace; a wireless receiver for receiving an in-field signal; a PLC intelligent control system which is used for processing in-field information; a dispatching and production upper computer management system whichis operated on a PC to process the information in the field and send out a control instruction; a clutch position detection device is arranged in each winch, each pair of winches are connected through a steel wire rope and are in charge of advancing and retreating of a boiler car corresponding to a furnace outlet; hard wiring is replaced by the PLC system, safety interlock is achieved, the life cycle statistics function of the device is achieved, the operation area covers the whole tapping area, the defects of a prior calcium carbide furnace tapping device are overcome, the staff is reduced,the production is increased, the operation cost of a production enterprise is reduced, and the automation level of the calcium carbide furnace is improved.

Description

technical field [0001] The invention relates to the technical field of calcium carbide furnaces, in particular to a three-rail six-hoisting calcium carbide furnace discharge control system and a control method thereof. Background technique [0002] At present, the winch control system for calcium carbide furnace is mainly realized by the winch, which is divided into two types: operation box operation and remote control operation. The area is limited, there is no necessary safety interlock between the winches, it is realized by complicated hard wiring, the level of automation is low, and the precision is poor. [0003] In the process flow of calcium carbide furnace, the accuracy and reliability of the operation of the boiler traction system in front of the calcium carbide furnace directly affects the safety and production efficiency of calcium carbide furnace smelting. At present, the winch control system for calcium carbide furnace is mainly realized by a pair of winches, w...

AI Technical Summary

Problems solved by technology

At present, the winch control system for calcium carbide furnace is mainly realized by a pair of winches, which are divided into two modes: operation beside the operation box machine and remote control operation. The operation point next to the operation box machine is fixed, and 2-3 people are required to cooperate to complete the operation, which is cumbersome. , Many operators are required, and the operating area is limited; the remote control has flexible operating points, but the anti-interference ability is poor, and there is no redundant operating point for each other. Once the remote control fails, the hoisting system of the calcium carbide furnace will fail Can not operate

The hoist clutch is not equipped with a separation and closing detection device, which cannot realize safety interlocking, and cannot fundamentally avoid production and safety accidents caused by the wire rope being broken

No PLC control system is used, all functions are realized through complex hard wiring, no automatic statistical function, single function, low efficiency, poor precision, urgently need to be upgraded
