Therefore, in order to solve the above-mentioned problems, an improvement is required to be made on the existing telescopic tube technology, so as to avoid the occurrence of the seizing phenomenon.
Disclosure of Invention
The utility model aims to provide a feeding system for an LF refining furnace, which aims to solve the problem that a telescopic blanking sleeve is easy to clamp in the prior art.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
a charging system for an LF refining furnace comprises a refining ladle and a discharging collecting hopper, wherein a water-cooling furnace cover is arranged on the refining ladle, a receiving port is arranged on the water-cooling furnace cover, and a reciprocating belt conveyor is arranged above the discharging collecting hopper; the refining ladle top is equipped with the guide rail, and the cooperation is installed reinforced dolly on the guide rail, unloading summary hopper is fixed on reinforced dolly, and unloading summary hopper bottom is equipped with the flap valve, unloading chute is installed to unloading summary hopper lower extreme.
Further, an air cylinder is arranged at one end of the guide rail, and the feeding trolley is driven to reciprocate on the guide rail through the expansion and contraction of the air cylinder.
Further, the other end of the guide rail is provided with a travel limiter, when the feeding trolley moves to the position where the other end of the guide rail contacts with the travel limiter, the travel limiter transmits a signal to the PLC, and the PLC stops feeding trolley and waits for the retraction operation instruction.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, the discharging collecting hopper of the LF refining furnace is arranged on the feeding trolley, the feeding trolley is driven to reciprocate on the guide rail by the expansion and contraction of the air cylinder, so that enough space is provided for uncovering the water-cooling furnace cover, and the problem that the automatic feeding system cannot be controlled due to the limitation of the structural space of a factory building is solved; the bottom of the blanking collecting hopper is provided with a flap valve, when feeding is needed, the PLC controller controls the feeding trolley to retract, and when the blanking inclined tube is in butt joint with a receiving port of the water-cooling furnace cover, the PLC controller controls the flap valve to open so as to feed the LF refining furnace. The movable trolley is adopted, so that the problem that the telescopic sleeve is easy to clamp during operation in the past is avoided, the stability is good during production operation, the production efficiency is improved, and the use safety and reliability are ensured.
