A hopper arch breaking device for friction and impact sensitive materials

Abstract

The invention discloses a hopper arch breaking device for materials sensitive to friction and impact and belongs to the field of solid material feeding. The hopper arch breaking device is suitable for the process of feeding solid materials sensitive to friction and impact and uses a conductive polymeric material as a material for making a hopper; an arch breaking shaft drives an arch breaking wheel to rotate along the axial direction of the arch breaking shaft when rotating around the direction of the symmetry axis of the hopper, so that elastic deformation is sequentially generated at different positions on the wall of the hopper, flowing of the materials in the hopper is prompted and the arching phenomenon of the materials in the hopper is eliminated. Due to no contact between the arch breaking wheel and the materials, friction and impact to the materials cannot be generated, so that safety of the feeding process is effectively ensured. The hopper arch breaking device has the advantages of high safety, good arch breaking effect, flexible use mode and the like.

Description

Technical field [0001] The invention relates to a hopper arch breaking device for friction and impact sensitive materials, which is suitable for the feeding process of solid materials sensitive to friction and impact. Background technique [0002] Traditional hoppers mostly use stainless steel as the material of the barrel. For the solid materials stored in the hopper, it is very common that the discharging process is not smooth and causes various problems such as bridging, rat holes (core pulling), and compaction. Yes, this will have a very large impact on the continuity, stability and accuracy of the feed, which will affect the consistency and quality of the product. The traditional solution is to beat the hopper wall, but this treatment will cause permanent damage to the hopper wall and the equipment connected to it. The impact force of mechanical rapping on the hopper is relatively large, so it will produce relatively large noise during the work. Due to the large impact, th...

The invention patent fluidized arch breaking device (application number 200510023441.4) discloses a device that uses compressed air to break the arch, including ash hopper, fluidized air pipe, ash unloading device, controller and high-speed pulse solenoid valve, but this During the use of the device, there will be dust flying, so it is only suitable for the arch breaking process of inert materials, and cannot be used for the arch breaking process of dusty combustible or explosive materials

The invention patent silo arch breaking device (application number 201010601621.7) discloses a mechanical stirring type arch breaking device, which can have a good arch breaking effect on solid materials, but due to the gap between the fixed sleeve and the movable sleeve There is a large friction, so it is not suitable for the arch-breaking process of friction-sensitive materials
