Kiln feeding dredging device and kiln

Abstract

The invention relates to the technical field of innocent treatment, in particular to a kiln feeding dredging device and a kiln. The kiln feeding dredging device comprises a driving assembly and a dredging assembly; the dredging assembly is used for extending into a feeding transition channel of the kiln; the driving assembly is connected with the dredging assembly to drive the dredging assembly toreciprocate along the feeding transition channel, and thus aluminum electrolysis waste cathode particles entering the feeding transition channel are scattered and are uniformly pushed into the kiln according to a fixed angle; the aluminum electrolysis waste cathode particles are prevented from being agglomerated by high-temperature flue gas in the kiln, the blanking repose angle of the aluminum electrolysis waste cathode particles is stabilized, the purposes of smooth feeding and stable material surface in the kiln are achieved, the stable input power of the kiln is ensured, and the reductionof productivity and quality fluctuation is avoided; the direction of the driving assembly is regulated and controlled by a first guide wheel, and the direction of the dredging assembly is regulated and controlled by a second guide wheel; the driving assembly and the dredging assembly are combined and connected through a universal joint and an insulating part; the oxygen isolation function is realized by a sealing assembly; and integral interlocking automatic control can be achieved.

Description

technical field [0001] The invention relates to the technical field of harmless treatment, in particular to a kiln feed dredging device and a kiln. Background technique [0002] The industrial technology of high-temperature method for harmless disposal and resource utilization of aluminum electrolysis waste cathodes is a difficult problem that is being overcome in this field. Moreover, each process link has its corresponding branch problems. Among them, the input of aluminum electrolysis waste cathodes The main problems are as follows: 1) The angle of repose of the waste cathode raw material will change with the change of the particle size of the raw material, resulting in an unstable material surface in the furnace; If the material is not smooth, the material surface in the furnace is unstable; 3) The high-temperature flue gas in the furnace will also consolidate and reunite the raw materials, resulting in poor feeding and unstable material surface in the furnace; and the u...
