Fine powdered coal forced feeder suitable for rotor metering scale

Abstract

The invention relates to a fine powdered coal forced feeder suitable for a rotor metering scale. The fine powdered coal forced feeder is characterized by at least comprising stirring blades, a barrel, a scraper, an upper plate, a rotor, a discharge port, a discharge pipe, a speed reduction mechanism, a driving shaft, a lower plate, a shell and an air inflation device, wherein the barrel is connected with the upper plate of the shell through bolts, the lower plate of the shell is connected with the discharge pipe through bolts, and accordingly a material channel is formed by the barrel, the shell and the discharge pipe; the rotor is fixed to the central position of the space between the upper plate and the lower plate of the shell, the lower plate is connected through bolts, and the lower end of the driving shaft is connected with a motor through the speed reduction mechanism; the driving shaft extends out of the upper end of the barrel from the upper plate, and the three layers of the stirring blades are horizontally fixed to the upper end of the barrel along the driving shaft. The feeder has the advantages of being good in manufacturability, simple in structure, reliable in sealing and the like.

Description

technical field [0001] The invention relates to a coal powder multilayer feeder, in particular to a fine particle coal powder forced feeder suitable for rotor weighing scales. Background technique [0002] The existing cement production lines are basically equipped with Pfister rotor weighing scales. All kinds of measurement data including feeding amount and load rate are clearly reflected on the computer screen, which is considered accurate enough. In fact, it is not the case, especially in terms of the load rate of the key weighing scale, because the physical fluidity of pulverized coal is easily affected by various objective factors and shows a large change in collapse, so that it can be used in the three links of unloading, feeding, and metering. On-site technical processing is very difficult, and the feeding control characteristics of the feeding pipe are poor. In the pulverized coal feeding link of rotary kiln firing, destructive out-of-control situations such as mat...

AI Technical Summary

Problems solved by technology

[0005] 1. Pulverized coal is easy to arch in the pulverized coal bin

[0006] 2. Due to the positive pressure inside the metering scale, the feeding pipe is easy to block

[0007] 3. Often there will be material punching and material breaking

[0008] 4. The load rate of the rotor metering scale fluctuates frequently
