At present, many large and medium-sized enterprises in the original coal bunker plugging coal (also known as shed coal, coal plug) problem is very serious (including import machine), not completely solve this problem, is bound to seriously affect the normal production of enterprises, and coal hopper Peng coal has great harm, light cause coal mill output decline, heavy cause coal hopper spontaneous combustion, even explosion. In order to solve this problem, our company developed the coal (material) warehouse automatic loose machine. It is suitable for all kinds of solid material storage bins and blanking tubes in electric power, metallurgy, mining, building materials and other industries.
1.Product details
At present, many large and medium-sized enterprises in the original coal bunker plugging coal (also known as shed coal, coal plug) problem is very serious (including import machine), not completely solve this problem, is bound to seriously affect the normal production of enterprises, and coal hopper Peng coal has great harm, light cause coal mill output decline, heavy cause coal hopper spontaneous combustion, even explosion. In order to solve this problem, our company developed the coal (material) warehouse automatic loose machine. It is suitable for all kinds of solid material storage bins and blanking tubes in electric power, metallurgy, mining, building materials and other industries.
2.Cause of blockage
The shape after plugging is roughly divided into arch, parabola, individual rat hole shape. Most of the blocked parts are within 1.5 meters of the coal gate. Somewhere in this range, thin layer materials begin to bond, increase the friction force after bonding, and then extend axial and radial, gradually increase the thickness, and eventually form different shapes and blockage, resulting in cut-off.
The upper mouth of the original coal bunker is large, the lower mouth is small, the upper mouth feeds, and the material falls from top to bottom by its own weight. The falling material flows in the conical container, so the more downward flow, the smaller the area of the material itself will form extrusion, increasing the four right Angle friction coefficient of the square cone. In addition, when the moisture content of pulverized coal reaches a certain level, it is very easy to clog.
3.effective solutions
Use loose machine dredge. The characteristics of the loose machine is to start from the blockage of the thin layer, through the internal disturbance, "assist" coal to overcome the external friction, and play the role of inducing the activation of coal, weaken the internal friction, damage the blockage of the foundation, to achieve the purpose of loose. Due to the large area of loose, can reach 5 square meters, loose strength, after the blockage can be automatically found, automatic start, loose smooth automatic stop and other reasons become a new generation of blocking equipment. Each set of loose machinery is composed of a number of curved scraper, hydraulic system and automatic working system adapted to the inner section of the coal hopper. The working principle is: when the raw coal bucket shed coal loose device to feel the coal signal, motor (1.5KW) drive the hydraulic system to work, loose machinery along the inner wall movement up and down, the shed coal "plow" through.
4、 Basic parameters for ordering
Provide the dimensions of the coal bunker's inlet and outlet, the height of the coal bunker, and the structure of the coal bunker can be in the form of cement, steel structure, or cement steel mixed structure.
The boiler form refers to the form of circulating fluidized bed boilers, coal powder boilers, and other boilers, which have the ability to work.
The center distance from the inlet to the outlet.
The height from the bottom of the coal bunker to the ground foundation.
