Drying device for metallurgical raw materials

Abstract

The invention relates to the technical field of metallurgy, in particular to a drying device for metallurgical raw materials. The drying device comprises a tank. Supporting frames are arranged at the bottom of the tank. A feeding inlet is formed in one side of the top of the tank. A discharging outlet is formed in the position, between the supporting frames, of the bottom of the tank. A motor is arranged at the top of the tank through a framework. A rotary shaft is arranged in the tank. The upper end of the rotary shaft penetrates through the top of the tank to be fixedly connected with an output shaft of the motor. A plurality of stirring rods are arranged on the side surface of the rotary shaft. A plurality of spray nozzles are arranged on one side of the tank at equal intervals, and one ends of the spray nozzles penetrate through one side of the tank to be arranged in the tank. The spray nozzles are connected through a pipe, a waste heat boiler is arranged at one end of the pipe, a filtration mechanism is arranged between the waste heat boiler and the pipe, and an air outlet is formed in the side, away from the spray nozzles, of the tank. According to the drying device provided by the invention, the materials are enabled to be in a loose state through the stirring rods, drying is facilitated, the drying speed is higher, accordingly the working efficiency is improved, and meanwhile, drying is thorough.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a drying device for metallurgical raw materials. Background technique [0002] In the pyrometallurgical process, smelting raw materials generally need to be dried before subsequent processing can be carried out, but the drying speed of the existing smelting raw material drying equipment is slow, resulting in low work efficiency. It is not uniform, which brings trouble to the subsequent processing. For this reason, we propose a drying device for metallurgical raw materials. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to propose a drying device for metallurgical raw materials in order to solve the shortcomings existing in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A drying device for metallurgical raw materials is designed, including a tank body, the bott...
