technical field

The utility model mainly relates to a slag removal device used in the field of metallurgy, in particular to an automatic slag removal device for water slag.

Background technique

Domestic slag produced after blast furnace smelting often adopts bottom filtration water slag treatment process, that is, the high-temperature slag is quenched and granulated by water and then flows into the filter tank. After the water is filtered through the filter layer in the filter tank, the grab crane is used to Grab the water slag, load it into a truck and transport it abroad. Due to the low degree of automation of the grab crane, the working environment is poor, and the efficiency is low, the cost is high, and the slag grabbing effect is poor.

At present, there is known a chain bucket reclaimer for reclaiming materials from grain depots or coal yards, which includes: a cart traveling mechanism, a trolley traveling mechanism that travels on the main beam of the cart traveling mechanism, and is used to grab the cart The chain bucket mechanism for loading materials, the lifting mechanism for lifting the chain bucket mechanism, the chain bucket lifting mechanism for driving the chain bucket to circulate and excavate materials, and the slag discharge mechanism at the upper end of the chain bucket mechanism to transport the water slag away The conveying mechanism, and the control mechanism for controlling the above-mentioned parts.

However, the chain bucket unloading device uses the chain bucket mechanism to excavate the materials on the ground. The fixed chain bucket mechanism cannot meet the working conditions of the blast furnace slag filter tank. After the chain bucket mechanism increases and moves, its lower end will be squeezed by the material. resistance in the horizontal direction. It is completely inapplicable when the chain bucket unloading device is applied to the cleaning of water slag in the metallurgical field. The filter tank is usually set below the ground. The length of the bucket mechanism (chain bucket lifting mechanism), due to the increase in the length of the chain bucket mechanism, the torque generated by the above-mentioned horizontal resistance will further increase, and the chain bucket mechanism will be deflected by force and affect the stability of the equipment. Moreover, due to the special environment of water vapor and humidity in the filter tank, the usual chain bucket is also easy to corrode and wear.
