Description
Technical field
The invention belongs to the process unit of ore dressing, especially relate to a kind of blockage-clearing device of ferro-concrete feed bin.
Background technology
The ore dressing plant in current all kinds of mines, is all provided with the storage warehouse (being designated hereinafter simply as feed bin) of mineral aggregate (ore), for regulating production procedure, distributing selected path, ore deposit, ore deposit and regulate into ore dressing amount, balanced ore dressing process.The pattern of feed bin, can be divided into square conical hopper storehouse, V flute profile disjunctor storehouse and cylinder flat-bottom bin etc.When mineral aggregate enters after feed bin, due to the difference of the physical factors such as water ratio, lumpiness and surface texture of mineral aggregate, cause that the friction force between mineral aggregate and bin wall increases, mineral aggregate can not lean on the gravity of self to overcome friction drag, cause mineral aggregate can not certainly slip out feed bin, often cause the sticky wall of mineral aggregate to stop up.Again because the water ratio of mineral aggregate is higher and granularity is very thin, in unit volume, the face area sum of mineral aggregate particle is very large, thereby binding force increases formation arcuation scaffold, on feed bin internal perisporium, there is material stock and can not discharge outside feed bin by deadweight overcome friction, when material stock is slight, in feed bin, form well shape scaffold, when material stock is serious, mineral aggregate can not flow in feed bin, just form and stop up, lose the function of feed bin completely, the feed bin Method of blockage removal of current use is: workman is lowered in feed bin, hand-held iron rod is disclosed material, or blow dredging up with dynamite, but in time, has personal injury and feed bin to damage to occur, there is potential safety hazard.
For solving the scaffold of feed bin, stop up, Chinese patent: ZL 2,009 1 0144875.8, disclose a kind of square cone infundibulate reinforced concrete feed bin and removed equipment and the using method thereof of stopping up scaffold.Its technical scheme of taking is: on the bulkhead of the interior tapered of feed bin, add multilayer strength and help stream airduct, be provided with the different strength of injection direction and help flow nozzle to jet in feed bin on airduct; Also in funnel bin, four property at parts of edges and corners are laid steel plate simultaneously, add pneumatic vibration hammer at the rear portion of steel plate, and rapping steel plate is discharged outside feed bin the mineral aggregate in feed bin.Although this scheme is stopped up scaffold to the removing of square cone infundibulate reinforced concrete feed bin and can be played a role, but there is following point: the block clearing of this scheme to cylinder flat shape reinforced concrete feed bin, just inapplicable, be mainly because: the inside of cylinder flat shape reinforced concrete feed bin does not have four corner angle, cannot install pneumatic vibration hammer additional, it is to help stream airduct in the inner installing of feed bin in addition, when mounted, must bring down stocks to install, thereby impact production, meanwhile, help stream airduct to be arranged on the inside of feed bin, by serious wear of a specified duration, also hinder the downslide of mineral aggregate in feed bin simultaneously; In addition, Chinese patent ZL2009 2 0187426.7 and ZL2009 2 0187425.2 are for square cone infundibulate reinforced concrete feed bin, also inapplicable to the block clearing of cylinder flat shape reinforced concrete feed bin.
