Technical field
The invention belongs to light calcined magnesia powder production technical fields, more particularly to a kind of block-proof type light-magnesite powder
Body feeding surge bunker.
Background technique
Currently, the production technology of light calcined magnesia mainly includes a variety of roastings such as reflecting kiln, rotary kiln, multihearth, shower furnace
Firing technique can all use feeding surge bunker although these roasting technique processes are had nothing in common with each other.
By taking magnesite powder as an example, it is divided into concentrate powder and mine tailing, and that there are partial sizes is small, moisture content is high and viscosity is big
Feature causes miberal powder that should not disperse.
Since feeding surge bunker plays the role of forming a connecting link in the production technology of light calcined magnesia, magnesite powder conduct
Raw material first passes through conveying equipment and is sent to feeding surge bunker, then enters measuring equipment by feeding surge bunker, finally enters roasting
Equipment is roasted, and light calcined magnesia finished product is finally obtained.
But the storehouse type structure of existing feeding surge bunker design and it is unreasonable, the bulkhead inclination angle of feeding surge bunker is smaller,
Miberal powder is easy to adhere in bulkhead inner surface, can be increasingly thicker by accumulating for a long time, blocks until by feeding surge bunker, at this time
It then needs manually to clean up the miberal powder that bulkhead inner surface is accumulated, once processing is not in time, or accumulation position is excessively high, Zhi Nengting
It is cleared up again after furnace, so not only influences production efficiency, and need additionally to pay a large amount of man power and material, so as to cause
The production cost of product increases.
In addition, the accumulation miberal powder to fall off also results in powder after manually disposing the miberal powder that bulkhead inner surface is accumulated
Press storehouse and the non-uniform problem of discharging.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of block-proof type light calcined magnesia powder feeding surge bunker,
