Breakage-proof buffering device for lump coal

Abstract

The invention discloses a buffering device, and particularly discloses a breakage-proof buffering device for lump coal. The breakage-proof buffering device comprises a supporting seat, wherein a head shield is arranged on the supporting seat; a chute which is oblique downwards is formed below the head shield; and the chute is a circular-arc curved chute. The chute is the circular-arc curved chute, so that sufficient centrifugal force is generated by the lump coal through acceleration, and the lump coal can perform set curvilinear motion in a buffering device; meanwhile, a centripetal acceleration is generated under the action of composite force, so that the direction of the lump coal is changed, the friction surface of the lump coal along the buffering device is transferred, a free-fall motion is changed into a specific curvilinear motion, the moving speed of the lump coal is lowered greatly, and the collision time of particles is prolonged; and meanwhile, in a process when particles become static from moving, a tangential-velocity component is generated, full non-elastic collision is avoided, and the lump coal is effectively prevented from being broken.

Description

technical field [0001] The invention relates to a buffer device, in particular to an anti-shatter buffer device for lump coal. Background technique [0002] Lump coal crushing is a complex process of changing the size of the material block, which is related to many factors. The main factors affecting the crushing of lump coal are: lump coal resistance, strength, hardness, toughness, shape, size, humidity, temperature, density and uniformity, as well as external conditions, such as the interaction and distribution of material block groups at the moment of crushing status etc. [0003] The above-mentioned factors all lead to the complication of the crushing process of lump coal, so a unified and complete theory has not yet been drawn to explain and guide the practice of lump coal crushing prevention. The crushing must have an external force to do work on the material and overcome the cohesive force of its particles. , the size of the cohesive force is also very different for...

Problems solved by technology

[0005] In the buffer device in the prior art, the chute is designed as a floor-type inclined setting. When the lump coal runs along the floor, its running track coincides with the floor. The force on the lump coal is the friction between the lump coal and the floor, and the lump coal itself. The gravity and the support force of the floor on the lump coal, the force on the lump coal is proportional to its movement speed, and inversely proportional to the collision time, the downward speed of the lump coal is the superposition of the acceleration generated by the three forces and the initial velocity, this way is in the weight And at the moment when the lump coal is reloaded and dropped, the collision will often cause the lump coal to break
