Description
Technical field
The utility model relates to a kind of anti-blocking clear plug equipment of ore storage warehouse, especially relates to a kind of pneumatic equipment that breaks up the formula eliminating blocking stocks from reinforced concrete ore bin, and the clear plug of ore dressing plant ore storage warehouse that can be used for all kinds of mines is anti-blocking.
Background technology
The ore dressing plant in current all kinds of mines all is provided with the ore storage warehouse, is used to regulate production procedure, distributes the selected path of ore, regulates the ore dressing amount, balanced ore dressing process.Ore storage bin adopts reinforced concrete structure mostly, the rectangular funnel storehouse.After ore put in storage, because physical factor differences such as ore water ratio, lumpiness, surface texture cause that ore increases with the friction force of bulkhead, thereby ore can not slip out ore storage bin under the self gravitation effect, causes the sticking wall of material to stop up.Again because material water ratio is higher, binding force increases and forms the arcuation scaffold, there are a large amount of material stocks not discharge outside the storehouse around in the storehouse, form well shape scaffold when slight, when serious by deadweight, square ore storage bin has become circular well head, material can not lean on from gravity and slip out ore storage bin, forms well shape scaffold, and the scaffold volume accounts for 1/3～1/4 of ore storage bin total volume, its result diminishes the actual use of ore storage bin volume, does not have the effect of regulating the ore dressing amount.Sometimes stop up scaffold when very serious, the material in the ore storage bin stops to flow, and ore storage bin loses its function.Current normally used sweep-out method is, the workman is lowered in the ore storage bin hand-held iron rod and discloses material, handles and blocks scaffold, and it is very dangerous work, the time fatal accident generation arranged.
For solving feed bin material blockage problem, Chinese patent CN201136668 discloses a kind of anti-blocking stream that helps and has broken up the medium feed bin, contain the feed bin warehouse, match with described warehouse and to be equipped with one at least and to overhang the formula vibrator, overhang the formula vibrator is installed in warehouse by erecting frame top, the driving snake and the vibrating head that overhang the formula vibrator overhang in the warehouse, and wherein vibrating head is positioned at the connecting portion of warehouse internal upper part warehouse and reducing closing in section centrum bottom warehouse.This breaks up the medium feed bin, does not change existing feed bin structure, does not change flowing power original in the storehouse, helps the stream effect better, can solve the blockage problem of material in the feed bin to a certain extent.This device is adapted at using under the feed bin charge amount is few, raw meal particle size is little and proportion is less, hardness the is little situation, ore storage warehouse for mine ore dressing factory, ore fragmentation is big, storage ore deposit amount is big and ore than great, hardness is big, adopt this device to solve and block the scaffold problem, and vibrating head quick abrasion, it is fragile to overhang the formula vibratode, and particularly under the situation that inventory is big in the storehouse, vibrating head is crushed to death easily, compacting and ineffective.
Summary of the invention
The purpose of this utility model is exactly the problems referred to above that exist at prior art, can remove thoroughly that ore storage bin blocks scaffold, guarantees ore dressing production smooth feeding and simple in structure, reliable operation, the easy to operate pneumatic equipment that breaks up the formula eliminating blocking stocks from reinforced concrete ore bin and provide a kind of.
The utility model in analyzing in detail ore storage bin block on the former gene basis that scaffold takes place and put forward.The major cause that material takes place to block in the ore storage bin is the sliding force that material is conducted oneself with dignity and caused greater than material with the friction drag of bulkhead.Influence and the principal element that causes are the inclination angle of bulkhead and the material friction coefficient with bulkhead, i.e. the physical property of both mating surfacess, as degree of finish, shape, lumpiness, water ratio and chemical property, as the bulkhead material with the affinity of material etc.
The major cause of material generation scaffold is in the ore storage bin, the binding force of material is very big, the internal friction coefficient that is material is very big, cause that material unites, this depends primarily on the physicochemical property of material itself, as the surface finish of material, the magnetic of the proportion of composing of material particles shape, lumpiness, lumpiness, water ratio and material itself.
For realizing above-mentioned purpose of the present utility model, a kind of pneumatic equipment that breaks up the formula eliminating blocking stocks from reinforced concrete ore bin of the utility model by the following technical solutions:
