Stock bin arch breaking device

Abstract

The invention provides a stock bin arch breaking device. The stock bin arch breaking device comprises multiple arch breaking pieces arranged in a bin body in a staggered mode, wherein the arch breaking pieces comprise hinge pieces arranged on the inners wall of contact plates and capable of rotating relative to the inner wall of the bin body; and the arch breaking pieces further comprise vibrationplates connected with the hinge pieces and capable of rotating relative to the inner walls of the contact plates, wherein clamping openings gradually shrinking from bottom to top are formed between the vibration plates and the inner walls of the contact plates, elastic assemblies are arranged in the clamping openings, one ends of the elastic assemblies are connected with the inner walls of the contact plates, and the other ends of the elastic assemblies abut against the vibration plates. According to the stock bin arch breaking device, the bridging and arching phenomena of materials in a stock bin can be effectively avoided and damaged through changing an internal structure of the stock bin, and the arch breaking capacity is high.

Description

technical field [0001] The invention belongs to the technical field of powder conveying machinery, and in particular relates to an arch breaking device for a silo. Background technique [0002] During the production and transportation of powder particles, the silo is an indispensable equipment. Due to the friction and cohesion between the particles and between the particles and the inner wall of the silo, the material near the wall of the silo does not flow. In order to improve this phenomenon, it is often necessary to design and install an arch breaking device on the silo. Common arch breaking methods include mechanical vibration, high-pressure airflow, etc. These devices have their own characteristics, but all have certain shortcomings. Once the near-wall side arch bridge is formed, the viscous layer will continue to extend inward and intensify due to the existence of friction and cohesion between particles. The energy of the mechanical vibration mode is transmitted fro...

Problems solved by technology

These devices have their own characteristics, but all have certain shortcomings. Once the near-wall side arch bridge is formed, due to the existence of friction and cohesion between particles, the viscous layer will continue to extend inward and intensify.

The energy of the mechanical vibration mode is transmitted from the warehouse wall to the material, which is beneficial to destroy the external friction of the material, but the effect of breaking the arch of the internal material is very limited; and the high-pressure air flow mode will have a certain impact on the product quality due to the introduction of the pressure gas medium. Influence, and once the water content of the pressure gas is brought into the powder material, it will cause the material to agglomerate and aggravate the blockage
