Prepressing feeder and system for feeding grain material in kiln

Abstract

The invention discloses a prepressing feeder, which comprises a hopper, wherein a feeding cabin is arranged at the bottom of the hopper; a feeding wheel is arranged in the feeding cabin; a distributing hole and a material sliding pipe are arranged at the bottom of the cabin; the outlet of the material sliding pipe is provided with a prepressing hammer; the material flux of the distributing hole at the bottom of the feeding cabin reduces gradually from one side to the other side along a circumferential direction; and the material sliding pipe is arranged in a way of inclining toward the side with small material flux relative to the longitudinal central line of the hopper. The feeder can assist a roller press in reasonably distributing powder material and prepressing the powder material in a feeding pit at the same time, thereby improving the formation rate and compactness of the grain material. The invention also discloses a system for feeding the grain material in a kiln of the prepressing feeder.

Description

technical field [0001] The invention relates to the field of raw material preparation in glass manufacturing enterprises, in particular to a pre-pressing feeder used for a pellet feeding kiln system. In addition, the present invention also relates to a pellet feeding kiln system equipped with the above-mentioned pre-press feeder. Background technique [0002] At present, the world's glass production has reached hundreds of millions of tons per year. Since 2008, my country's glass production has jumped to the first place in the world, about 50 million to 60 million tons per year. As a large-scale industry, does its production meet the requirements? The requirement of energy saving and emission reduction is a very important technical indicator. [0003] Since the birth of the glass industry in my country in the 1930s, glass batches have been fed into the kiln in the form of powdered bulk materials. This is a relatively backward method, which has the following disadvantages: ...

AI Technical Summary

Problems solved by technology

[0012] Since there is only a hopper 3' above the rolling machine, the powder 3' naturally flows into the material distribution area of ​​the roller 1' under the action of gravity, which may easily cause the rolling machine to not work normally

If the feeding amount is too large, the excessive powder will fill the entire material distribution area, and then block the roller so that it cannot rotate. If the feeding amount is too small, a small amount of powder will not be able to fill the material pit on the roller. It cannot be extruded into pellets

In addition, the uniformity of the powder entering the material pit 2' cannot be controlled, and the necessary pre-pressing process is lacking, resulting in a low forming rate and density of the pellets, which cannot meet the production requirements of modern glass manufacturers
