Briquette clamp for cylindrical briquettes

Abstract

The invention relates to an auxiliary device of a briquetting hydraulic molding machine for metallurgical direct reduced iron, in particular to a briquette clamp for cylindrical briquettes, which comprises two positioning plates and a plurality of supporting plates, wherein the plurality of supporting plates are verticality and fixedly installed and combined with the two positioning plates according to a certain space into a briquette clamping frame; the briquette clamp is characterized by also comprising a driving device, a guiding device, claws and an elevating mechanism, wherein the claws are relatively distributed in pairs and respectively connected with the briquette clamping frame through the driving device and the guiding device; the elevating mechanism is installed on the support plates outside the briquette clamping frame; each claw comprises a clamping surface and a clamping bracket; and the clamping surface is provided with a circular surface adaptive to the exterior shape of the cylindrical briquette. By the clamping of the claws and the elevating and falling of the elevating mechanism, the function of clamping the cylindrical briquettes is realized, so that a briquette moving car can deliver the briquettes out from a forming machine, and the invention has simple structure and convenient operation, reduces breakage of the cylindrical briquettes in handling, improves the quality of products, dispenses with manual handling, and improves the production efficiency.

Description

technical field [0001] The invention relates to an accessory device of a metallurgical direct reduction iron briquetting hydraulic forming machine, in particular to a blank holder for cylindrical blanks. Background technique [0002] The existing process method used in the production of direct reduced iron is to firstly process the raw materials, then press the fine ore powder into briquettes with briquetting equipment, and then put the pressed fine ore powder briquettes into the reduction crucible. Add deoxidizer and desulfurizer into the pot, then discharge the crucible neatly on the vehicle, push the vehicle into the reduction furnace through the running vehicle, and go through the three processes of preheating, reduction and cooling in the reduction furnace. Finally, the direct reduced iron is produced out of the furnace. In the production process, the fine ore powder is pressed into briquettes with briquetting equipment, and the briquettes are loaded into the reduction ...

[0002] The existing process method used in the production of direct reduced iron is to firstly process the raw materials, then press the fine ore powder into briquettes with briquetting equipment, and then put the pressed fine ore powder briquettes into the reduction crucible. Add deoxidizer and desulfurizer into the pot, then discharge the crucible neatly on the vehicle, push the vehicle into the reduction furnace through the running vehicle, and go through the three processes of preheating, reduction and cooling in the reduction furnace. Finally, the direct reduced iron is produced out of the furnace. In the production process, the fine ore powder is pressed into briquettes with briquetting equipment, and the briquettes are loaded into the reduction crucible from the inside of the press. into the crucible, because the briquettes are manually loaded into the crucible, the placement and uniformity of the briquettes in different crucibles are inconsistent, so that the quality of the reduced direct reduced iron is also uneven. Through manual handling, the production Low efficiency is not conducive to the realization of direct reduced iron mechanization, automation and large-scale production
