Description
Technical field
The invention belongs to selecting and purchasing ore deposit equipment technical field, be specifically related to a kind of square cone-shaped metal feed bin block clearing equipment and using method.
Background technology
The ore dressing plant in current all kinds of mines, is all provided with ore storage warehouse, for regulating production procedure, distributes the selected path of ore, regulates into ore dressing amount balanced ore dressing process.Ore storage bin pattern can be divided into: the tapered funnel bin of square, V grooved disjunctor storehouse and cylinder flat-bottom bin etc.After ore puts in storage, due to physical factor differences such as ore water ratio, lumpiness, surface textures, cause that ore increases with the friction force of bulkhead, thereby ore can not overcome friction drag under self gravitation effect, slip out ore storage bin, cause the sticky wall of material to stop up.Again because material water ratio is higher, granularity is very thin, unit volume endoparticle surface sum is very large, thereby binding force increase, forming arcuation scaffold, storehouse internal perisporium has a large amount of material stocks not overcome outside internal friction discharge storehouse by deadweight, when slight, form well shape scaffold, when serious, material can not flow in storehouse, forms and stops up, and loses the function of ore storage bin completely.The Method of blockage removal of current use is: workman opens one and discloses material hole and disclose material on bulkhead, or is lowered to hand-held iron rod in ore storage bin and discloses material, or blows up with dynamite and dredge, and time has fatal accident and ore storage bin to damage to occur.
Stop up for solving feed bin scaffold, Chinese patent ZL200910144875.8 discloses a kind of square cone funnel type reinforced concrete ore storage bin, remove equipment and the using method of stopping up scaffold, the technical scheme that this patent is taked is: on the inwall of the inside of warehouse (instead of outside), add multilayer strength and help stream airduct, on airduct, being provided with the different strength of injection direction helps flow nozzle to jet in storehouse, also lay steel plate at four corner angle of funnel bin simultaneously, add pneumatic vibration hammer at steel plate rear portion, rapping steel plate, blow shake in conjunction with under storehouse materials inside is discharged outside storehouse.In this technical scheme, there is following point: first it can play a role to the not high powder of square cone funnel type reinforced concrete ore storage bin removing viscosity, but just helpless to removing heavy body powder, because of heavy body powder, to shake more real and more real, especially at feed bin trunnion place, cohesive powders has formed spherical, rolls in ore storage bin exit, form rolling scaffold, in storehouse, material cannot be discharged outside storehouse.This scheme in addition, helping stream airduct to be arranged in inside wall of ore bin, hinders supports for material down-sliding in storehouse, helps stream airduct serious wear, and must bring down stocks while installing, impact production.In storehouse, four jiaos of laying steel plate work capacitys are very large, add vibration hammer, and cost is high, to cohesive powders, shakes more real and more real, not applicable.Chinese patent 20092018742.7 and Chinese patent 200920187425.2, all for reinforced concrete ore storage bin, are mainly processed the material that viscosity is not high, are also reluctant to high-viscosity material.
