Abstract

The invention relates to the field of metallurgy and is intended for transportation, heating and unloading of the charge and other materials when filling them in the charging devices of electric furnaces, crushers and other mechanisms. The aim of the invention is to increase the efficiency of heating, drying and transporting the charge of various fractions, including small ones, and eliminating clogging of the holes in the flaps of the tub bottom. The bag for transportation, heating, drying and unloading of the charge includes a lined casing with a removable conical muffle and grooves having a double-sided tooth at the lower end locking the hinged bottom flaps, the latter made in the form of a metal sheet with rectangular cuts, covered with casing, made in the form of semi-cylinders with holes in them at the level of the sheet of the bottom flaps. In this case, the distribution of hot gases over the cross section of the bottom is carried out by a corresponding distribution of the number of holes in the protective covers. In order to smoothly discharge the charge from the tub, the protective covers are arranged perpendicular to the bottom flap connector line. 1 hp f-ly, 2 ill. I cl

Description

 ate

The invention relates to metallurgy and is intended for transportation, heating, drying and unloading of the charge and other materials when filling them into the charging devices of electric furnaces, crushers and other mechanisms.

The purpose of the invention is to increase the efficiency of heating, drying and transporting the charge of various fractions, including small ones, and eliminating clogging of the holes in the bottom panels and the tubs.

FIG. 1 shows the proposed tub, longitudinal section; in fig. 2 - the same, top view.

The tub includes a casing 1 with a heat insulating lining 2 and a replaceable inner muffle 3, hinged bottom flaps 4 with channels for the passage of hot gas, and protective covers 5 providing hot gas at the level of the bottom flap sheet and the mechanisms 6 of the bottom opening . When heating and drying the batch and other materials, the bucket is filled with a heating device, and the base is closed using these cusps of the bottom 4 on the stand 7, through which the heated gases are supplied to the bottom. Hot gases, a passage from the bottom upwards through the holes in the bottom flaps and protective covers, enter the cage, heat it, remove moisture and pass the charge, come under the umbrella of the suction system, the speed of movement of hot gases in which is very small and, therefore, there is no removal.

After the preheating is completed, or the tank shelf is transported to the support site at the unloading site, mounted on it, and the tub bottom mechanism opens automatically and the cage is unloaded.

Claims (2)

Invention Formula . Bad for loading, heating and drying the mixture, containing a lined casing with a removable conical muffle and grooves, in which pins are placed, connected to rods with a double-sided tooth at the lower end, which locks the hingedly fixed flaps of the bottom, characterized by the fact that in order to increase the efficiency of heating, drying and transporting the charge of various fractions, including small ones, and to avoid clogging of the holes in the cusps of the tub bottom, the cusps are made in the form of a metal sheet with rectangular cutouts, covered with protective skin s made in the form of semi-cylinders with holes in them on the leaf level of the bottom flaps. 2. Bad under item 1, characterized in that, in order to unload the material unhindered, the protective covers are arranged perpendicular to the bottom flap connector line. FIG. 2
