Description
Technical Field
The invention relates to the technical field of bin blocking prevention, in particular to an intelligent pneumatic blocking prevention type bin and a using method thereof.
Background
The raw material working section of the coal preparation workshop generally adopts a feed bin to carry materials, the materials slide down smoothly and the problem of blocking materials exists in the use of the existing feed bin, the normal production work is seriously affected, and the production efficiency is reduced. The analysis shows that the reasons for unsmooth material running are mainly caused by two factors: material properties and steel bin shape.
Material characteristics: the main factors of easy aggregation and agglomeration of materials are moisture and granularity, the dry ore with small moisture content has small viscosity and is not easy to be aggregated, and the material with overlarge moisture content has large conveying inertia and strong fluidity and is not easy to be agglomerated. Only when the water content of the coal is 12% -18%, the self-adhesion property of the material is outstanding, and the material is easy to be attached to the inner wall of the steel bin and is agglomerated and hardened, so that the material is not smooth in sliding. The granularity of the material is also the cause of unsmooth operation of the material, and the blocky ore is difficult to be blocked due to large conveying inertia and large kinetic energy. The material with granularity smaller than 50 μm has small motion inertia, is not easy to slide down, is paved on the inner wall of the steel bin, increases the friction force of the material sliding down, reduces the material sliding down energy and finally forms funnel-shaped or rat hole-shaped blocking materials, and if the material cannot be obtained and processed in time, then forms bridge-shaped or arch-shaped blocking materials, and the steel bin is completely blocked.
Steel bin shape: the geometric shape of the steel bin has great influence on the mobility of materials, in theory, the steel bin is cylindrical in shape, the closer the angle of the steel bin is to be vertical, the opening of the outlet of the steel bin is equal to or larger than the opening of the inlet, and the lower the friction coefficient of the lining material is, the less the blocking phenomenon is easy to occur.
The prior art generally adopts equipment such as a vibrator, an air cannon and the like which are added on the outer wall of the steel bin to clear the blockage. The air cannon can release energy once, but uncontrollable, and the material blocks damaged by hardening can fall off in a large area to cause secondary blocking, and can only form holes, so that blocking cannot be thoroughly solved. The high-frequency vibration of the vibrator can lead to metal welding fatigue of welding points of the steel bin, damage to the steel bin and surrounding equipment and reduction of the service life of the equipment. In addition, the high-frequency vibration of the vibrator can enable the lower-layer material to be more compact under certain conditions, the flow performance is poorer, the problem of blocking is aggravated, and the difficulty of manual blocking removal in the later period is increased. Therefore, the two ways of blockage removal effect is still unsatisfactory, and blockage occurs frequently, so that the blockage prevention improvement of the steel bin is urgent.
