Technical Field
The utility model belongs to the technical field of the pouring material production facility, concretely relates to a drying device for blast furnace tapping runner base.
Background
Modern big blast furnace tapping runners generally use high-quality low cement castable, because the castable pouring density is high, for the refractory ramming material of same material, the refractory castable is more resistant to erodeing, therefore life is longer, but the iron runner of traditional low cement refractory castable pouring must just can come into use through processes such as maintenance hardening, stoving, wherein in order to ensure the effect of stoving, generally need the staff to dry 1-4h according to experience, the error is great, waste time, consequently need improve current drying equipment, the concrete time of conveniently confirming the stoving completion.
SUMMERY OF THE UTILITY MODEL
In view of the above, an object of the present invention is to provide a drying device for a blast furnace tapping channel blank, so as to solve the above problems.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a drying device for blast furnace iron runner base, both ends open-ended stoving case around including, the inside level of stoving incasement sets up and is upper and lower parallel distribution has two stoving boards, be equipped with the mould between two stoving boards, the guide pulley is all installed on mould left and right sides upper portion, the lateral inner wall is provided with movable guide and fixed guide about the stoving case, movable guide is upper and lower slip with the fixed guide middle part and cup joints, and under the original condition, movable guide's highly is higher than fixed guide, fixed guide and stoving case lateral wall fixed connection, the movable guide below is equipped with the layer board, the layer board is fixed at stoving case lateral wall and corresponds the position, fixedly connected with bearing spring between layer board and the movable guide.
Preferably, the lower side of the middle part of the fixed guide rail is provided with a limiting block for preventing the movable guide rail from falling off.
Preferably, the movable guide rail and the fixed guide rail are inclined backwards by 3 degrees, so that the guide wheel can move backwards conveniently.
Preferably, the front part of the upper side of the movable guide rail is arc-shaped, so that the guide wheel can conveniently move from the fixed guide rail to the movable guide rail.
The utility model has the advantages that: the utility model is provided with a guide wheel which is convenient to move on a fixed guide rail and a movable guide rail, when the guide wheel moves on the movable guide rail, the guide wheel is compressed under the action of gravity of the mould and a blast furnace iron runner blank to cause the movable guide rail to move downwards, the height of the movable guide rail is lower than that of the fixed guide rail, the guide wheel is limited on the movable guide rail to prevent the guide wheel from moving, thereby facilitating the drying work of a drying plate, after the drying is finished, the weight of the blast furnace iron runner blank and the mould becomes light, the compression degree of the bearing spring is continuously smaller, the movable guide rail moves upwards, after the rear end of the movable guide rail is aligned with the fixed guide rail, the guide wheel moves on the fixed guide rail to drive the mould to move to the rear end of a drying box, the mould is moved out of the drying box, the position of the movable guide rail is adjusted by the weight change of the blast furnace iron runner blank in the drying process, the mould provided with, and subsequent work is carried out, so that the time is saved, and the working efficiency is improved.
