Cylinder material mixing device

Abstract

The invention discloses a cylindrical mixer which is used for solving the problem that the structure of existing cylindrical mixers can not be largely improved. The cylindrical mixer comprises a cylinder with openings at two ends, a ring gear is hooped on the outer circumference of the cylinder, a motor arranged outside the cylinder is connected with a transmission gear by a speed reducer, and the transmission gear is matched with the ring gear; the front and the rear of the cylinder are provided with a feeding conveyer and a discharge conveyer; a central shaft with two ends extending outside the cylinder is arranged inside the cylinder, the central shaft is connected with the cylinder by a collecting mechanism, the two ends of the central shaft are connected with a bearing seat by a bearing, and the bearing seat is fixed on a bracing structure. The cylindrical mixer is applicable to mixing iron making materials into balls.

Description

technical field [0001] The invention relates to a kind of equipment for mixing materials into balls, in particular to a cylinder mixing machine used in sintering plants of iron and steel enterprises. Background technique [0002] In the technological process of iron and steel enterprises, the concentrate powder, fuel, flux and other materials are usually mixed by a mixer, pelletized and then sintered, and the sintered ore is sent to the blast furnace for smelting; at present, in the existing various mixing Among the feeders, the cylinder mixer has the characteristics of stable operation, large single machine output, good mixing effect and good ball forming performance due to its circular symmetrical structure, so it is widely used in iron and steel enterprises. [0003] However, because the cylinder structure of the existing cylinder mixer is generally a thin-walled structure, it must bear local support loads during work, and the strength of the cylinder limits the expansion...

Problems solved by technology

[0003] However, because the cylinder structure of the existing cylinder mixer is generally a thin-walled structure, it must bear local support loads during work, and the strength of the cylinder limits the expansion of the diameter and length of the cylinder, thereby limiting the equipment. Large-scale

At the same time, the support structure of the cylinder generally adopts two or more sets of support rollers, and the cylinder relies on friction to drive the support wheels to rotate. Therefore, the power consumption of the motor is high, which makes the energy consumption of the whole machine high.

[0004] At present, my country's iron and steel industry is in the development stage of expanding scale, and the equipment of enterprises is developing in the direction of large-scale, especially the capacity of blast furnaces is constantly expanding, and the area of ​​corresponding sintering machines is also expanding. Therefore, the mixing equipment for sintering machines The capacity must also be expanded accordingly, and the larger the diameter of the mixer, the better the effect of material mixing and ball formation, but the structure of the existing cylindrical mixer limits the increase of its equipment capacity, and the equipment consumes a lot of energy
