Mixer damping apparatus

Abstract

The invention discloses a mixer damping apparatus. The apparatus is mounted at two supporting wheels at the feeding end or the discharging end of a cylindrical shell, and comprises a fixed support, amovable support, a limiting and locking device and cushions; the fixed support is fixed on a pedestal, and is located at the outer side of one of the two supporting wheels, and is in contact fit withtwo supporting wheel bearing seats at two ends of the one supporting wheel; the movable support is movably arranged on the pedestal, is located at the outer side the remaining supporting wheel, and isin contact fit with two supporting wheel bearing seats at two ends of the remaining supporting wheel; the limiting and locking device is respectively connected with the fixed support and the movablesupport; and every cushion comprise a first cushion and a second cushion, the first cushions are mounted between the bases of the supporting wheel bearing seats and the pedestal, and the fixed supportand the movable support are in contact fit with the supporting wheel bearing seats through the second cushions. The apparatus can eliminate the rigid collision between the supporting wheels and a roller way and absorb the impact force between the supporting wheels and the roller way when the cylindrical shell jumps in order to avoid the damages of the rigid collision and the impact force to a mixer.

Description

technical field [0001] The invention relates to the technical field of sintering equipment, in particular to a mixer damping device. Background technique [0002] During the sintering production process, the mixer is mainly responsible for the mixing and pelletizing of the sintered material. At present, with the development of sintering technology, large-scale sintering machines are becoming more and more popular, and the specifications of cylinder mixers used in conjunction with sintering machines are also increasing. [0003] The mixer in the prior art comprises a cylinder body, a roller table, a supporting wheel, a supporting wheel bearing seat and a base. Among them, the barrel of the mixer is usually fixed and supported by four steel supporting rollers, and each supporting roller is equipped with a supporting roller bearing seat at both ends of the axial direction, and each supporting roller is set by two supporting roller bearing seats at both ends. On the base; the ...

AI Technical Summary

Problems solved by technology

[0005] Due to the large size of the barrel of the large cylinder mixer and the large operating load, after a long period of operation, there will be deformation of the barrel, wear of the roller table and wear of the transmission ring gear, which will cause the barrel and the Serious vibration of the supporting wheel, frequent high temperature of the supporting wheel bearing, and frequent shedding of the liner of the cylinder; at the same time, due to the vibration of the cylinder, the roller table of the cylinder body collides with the roller skin of the supporting roller, which will cause the roller table of the mixer and Problems such as wear and peeling of the idler roller skin, shattering and loosening of the system foundation, and toothing of the large and small ring gears affect the normal use of the mixer
