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 mine, is all provided with ore storage storehouse, for regulating production procedure, distributing ore and being selected in path, regulating 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, because the physical factors such as ore water ratio, lumpiness, surface texture are different, cause ore to increase with the friction force of bulkhead, thus ore can not overcome friction drag under self gravitation effect, slips out ore storage bin, causes material to glue wall blocking.Again because material water ratio is higher, granularity is very thin, unit volume endoparticle surface sum is very large, thus binding force increases, and forms arcuation scaffold, and storehouse internal perisporium has a large amount of material stock can not overcome outside internal friction discharge storehouse by deadweight, well shape scaffold is formed time slight, time serious, material can not flow in storehouse, forms blocking, 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 under enter hand-held iron rod in ore storage bin and disclose material, or blow up with dynamite and dredge, in time, has fatal accident and ore storage bin to damage to occur.
For solving the blocking of 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 blocking scaffold, the technical scheme that this patent is taked is: on the inwall of the inside (instead of outside) of warehouse, add multilayer strength help stream airduct, airduct is provided with the different strength of injection direction helps flow nozzle jet in storehouse, also lay steel plate at funnel bin four corner angle simultaneously, pneumatic vibration hammer is added at steel plate rear portion, rapping steel plate, blow shake combine under storehouse materials inside is discharged outside storehouse.Following point is there is: first it can play a role to the powder that square cone funnel type reinforced concrete ore storage bin removes viscosity not high in this technical scheme, but it is just helpless to removing heavy body powder, because of heavy body powder, shake more real and more real, especially at feed bin trunnion place, cohesive powders has been 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, and help stream airduct serious wear, and must bring down stocks when installing, impact is produced.In storehouse, steel plate work capacity is laid very greatly in corner, and add vibration hammer, cost is high, to cohesive powders, shakes more real and more real, not applicable.Chinese patent 20092018742.7 and Chinese patent 200920187425.2 are all for reinforced concrete ore storage bin, and the material that main process viscosity is not high is also reluctant to high-viscosity material.

Detailed description of the invention
For further describing the present invention, below in conjunction with drawings and Examples, square of the present invention tapered metal feed bin block clearing Apparatus and operation method is described in more detail.
On four ore storage bin cone walls 37 of ore storage bin 34, each cone wall is respectively equipped with three groups and helps flow nozzle group, ground floor nozzle block 30 (basecoat), be equipped with 4 and help flow nozzle 27, second layer nozzle block 29, is equipped with 6 and helps flow nozzle 27, third layer nozzle block 28, be equipped with 8 and help flow nozzle 27, four faces, ground floor, has 16 and helps flow nozzle, the second layer has 24 and helps flow nozzle 27, and third layer has 32 and helps flow nozzle 27.Each nozzle block is provided with an ecp butterfly valve 13 and the first ecp actr 14, and each conical surface has 3 ecp butterfly valves 13.Each nozzle helps stream 27 to be penetrate separately bulkhead 37 to enter in storehouse, and seals with between bulkhead, prevents material in storehouse from leaking.Each ecp butterfly valve 13, is fixed with ore storage bin cone wall 37 by support.The admission port of each ecp butterfly valve 13 is connected with helping stream pipeline 24, helps stream pipeline 24 to connect with ecp ball valve 20; The admission port of ecp ball valve 20 helps circulation flow path 12 to communicate with main, main helping flows pipeline about 12 points two-way, converge rear same second boiler check valve 10 to connect, second boiler check valve 10 flows storage tank 8 UNICOM through the 4th manual ball valve 9 with helping, the first ecp actr 14 (butterfly valve is used) on each operated pneumatic valve, and the second ecp actr 21 (ball valve with) all with pilot piping 25 UNICOM, again with the 3rd two-position two-way solenoid valve 22, source of the gas process three linked piece 19 UNICOM, connect the 3rd manual ball valve 6 through main control pipeline 11 and control storage tank 4.Main control pipeline about 11 points two-way, enter the 3rd manual ball valve 6 jointly.Cleaner 6 is arranged on trunnion 35 by cleaner fixed mount 38, and cleaner fixed mount 38 is welded on trunnion 35.The admission port of the automatic reciprocating air cylinder on cleaner 16 is connected with pilot piping 25 through the second two-position two-way solenoid valve 18, and the admission port of block clearing bar 17 flows pipeline 24 through the first two-position two-way solenoid valve 15 and communicates with helping.
Air compressor 1 is screw-rod air compressor, and blast is 0.8MPa, and air quantity is 6m
3/ min, the high pressure gas extruded are through manual ball valve 2, boiler check valve 3, enter control storage tank 4, entering through minimal pressure hold-off valve 7 simultaneously and help stream storage tank 8, the effect of minimal pressure hold-off valve 7, is ensure that the pressure of control storage tank 4 is not less than 4MPa at work, for making to save energy in inflation, manual ball valve 5 can be opened at the inflation initial stage, control storage tank 4 is communicated with helping stream storage tank 8, close after gas of substituting the bad for the good.
When blocking occurs ore storage bin 34, carry out block clearing by following method:
In normal work, Air compressor 1 is in open state, and when control storage tank 4 with when helping stream storage tank 8 to be all filled to 0.7MPa, Air compressor 1 can self-servicely be shut down, and energy Auto Power On when air pressure is low, the pressure of whole air-channel system is higher than 0.4MPa.When feed bin needs block clearing, operating personal is connected and is controlled power supply, now, green light on electric cabinet 33 panel, A.C. voltmeter display AC220V, DC voltmeter display DC24V, then pneumatic ball valve 20 is connected, with the second two-position two-way solenoid valve 18, open respectively and help gas source and control source of the gas, open pressurized air and start to help stream.
When feed bin bottom, trunnion 35 place blocks, and opens cleaner 16, connects the second two-position two-way solenoid valve 18, makes cylinder make automatic reciprocating motion, connects the first two-position two-way solenoid valve 15, dispels sticky group to block clearing bar 17 air feed.When block clearing, belt feeder 36 must operate, otherwise blocking is more serious, and each block clearing, duration of ventilation does not exceed 3 seconds, and time gap is not lower than 3 seconds.On pilot piping, compression indicator 26 is housed, help on stream pipeline and compression indicator 23 is housed, distribution box with protectors 31 is housed on the left of ore storage bin, and distribution box with protectors 32 is equipped with on right side.
