A uniform automatic feeding device for a large melting furnace

Abstract

The invention relates to a feeding mechanism for a smelting furnace, in particular to a uniform automatic feeding device for a large smelting furnace. Including the deflection mechanism, the deflection mechanism is equipped with a telescopic loading arm, the front end of the telescopic loading arm is provided with a linkage hopper, the rear end of the telescopic loading arm is provided with a motor for adjusting the length of the telescopic loading arm, and the telescopic loading arm is connected with a Anti-tipping device. Compared with the prior art, the hopper of the feeding device of the present invention can move forward and backward in the furnace with the telescopic feeding arm, and can deflect and move left and right, so as to realize uniform feeding in all positions in the furnace. The multi-position of the hopper is evenly and automatically fed, and the efficiency is high. The uniform distribution of the charge is beneficial to the uniform heating of the charge, reducing the burning loss of elements in the metal charge, and the temperature in the furnace is uniform, which is beneficial to the improvement of the quality of metal smelting. The telescoping, deflecting, and hopper turning control parts of the feeding device are located outside the furnace, avoiding the high temperature in the furnace, with high reliability and long service life. The feeding device can be installed on a track-type or wheel-type feeding trolley for transportation in front of the furnace.

Description

technical field [0001] The invention relates to a feeding mechanism for a smelting furnace, in particular to a uniform automatic feeding device for a large smelting furnace. Background technique [0002] In the melting and casting production of non-ferrous metals, it is necessary to add non-ferrous metal blocks into the melting and casting furnace for heating and melting, and then cast them into ingots. At present, the feeding method of large-scale smelting furnaces is to manually pry them into the melting and casting furnace with a crowbar or push them into the melting and casting furnace with a forklift. In such a feeding method, the amount of charging each time is small, and the overall charging efficiency is not high, and the randomness is large, and the charging port of each melting and casting furnace must be equipped with a special person for continuous feeding. At the same time, the ambient temperature is high, the dust is large, and the working environment of the o...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: the feeding method of the existing large-scale smelting furnace is inefficient, and the feeding time, quantity, and position are unbalanced, resulting in a large temperature difference between the inside and outside of the smelting furnace and obvious temperature fluctuations, which reduces the smelting efficiency of the equipment, and the smelting The impact force on the inner wall of the furnace is large, which reduces the service life of the equipment and affects the quality of metal smelting
