3left and right just need once be cleared up; and the tailings slurry agitation in sand storehouse is more full and uniform; there is the dead angle phenomenon of buildup hardly; and increase the filling capacity of tailings slurry; significantly power generating ratio number of times, makes operating efficiency significantly at least improve 80%, extension device life cycle; and significantly reduce labour intensity, easily implement.
Description
Technical field
The utility model relates to a kind of injection nozzle, specifically belongs to the nozzle that can prevent buildup in filling in mine mining vertical sand warehouse.
Background technology
At present, in filling in mine mining, vertical sand warehouse nozzle used is due to its structure problem, and namely the injection direction of fumarole can only be that it can only complete the fluidization effect of the dense compacting tailings of vertical sand storehouse cylinder warehouse part along nozzle center axially upwards or/and vertical axial sprays.In production and application, owing to being bullet shape bottom vertical sand warehouse, therefore fully can be stirred fluidization in the centre of last mortar at the bottom of the cone of sand storehouse that release of fluidization, but then produced accumulation by hanging fascia at the compacting tailings of sand storehouse centrum warehouse and cylinder warehouse joint portion and adjacent domain thereof and become dead angle.As time goes on, packing phenomenon is serious, and sand storage capacity constantly declines.In order to ensure tailings fluidisation pulping and put sand effect and sand storehouse dischargeable capacity, regularly must empty sand storehouse, change inefficacy nozzle, packing job just can proceed, and the timely establishment officer that namely needs to stop production clears up, and removes buildup in storehouse, general every filling 7000m
3just need organize and once clear up, need 3 ~ 5 day time of shutdown just can complete, cause the mining with stowing production efficiency in mine low.
Through retrieval, it is axial upwards or/and vertical axial sprays that vertical sand warehouse uses nozzle spray direction to be along nozzle center, has the method that two kinds process vertical tailings storehouse tailings and overstock at present:
(1) vertical sand warehouse cone pulping geomantic omen, end pipe adopts concentric ring round to arrange, same circle nozzle adopts the different elevation angle of installing to expand fluidization scope successively, reduces tailings and overstocks
(2) vertical sand warehouse cone pulping geomantic omen, end pipe adopts radial with one heart, makes different radial geomantic omen pipe fluidization scope superposition, improves tailings efficiency of fluidization, reduce tailings and overstock.
Above two kinds of methods are optimizes nozzle arrangement arrangement to expand fluidisation area, and raising fluidization efficiency reduces tailings and overstocks situation, and not starting with from change nozzle arrangements aspect, it is overstocked to reduce tailings.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, provides one that tailings can be made at 20000m
3left and right just need once be cleared up, and significantly improves operating efficiency, the nozzle that can prevent buildup in filling in mine mining vertical sand warehouse of extension device life cycle.
Realize the technical measures of above-mentioned purpose:
The nozzle of buildup in filling in mine mining vertical sand warehouse can be prevented, by nozzle body, the spray orifice be located on nozzle body, the Compress Spring be located in nozzle body, be placed in the pushing pearl on Compress Spring one top, withstand on pushing pearl and be connected font with nozzle body and take over, take over middle font the nozzle connection be connected to form, it is: be provided with at least one injection hole at the upper top end face of nozzle body; Spray orifice on nozzle body is inclined.
It is characterized in that: the gradient of inclined spray orifice is at 20 ~ 60 °.
The utility model is compared with prior art: tailings can be made at 20000m
3left and right just need once be cleared up; and the tailings slurry agitation in sand storehouse is more full and uniform; there is the dead angle phenomenon of buildup hardly; and increase the filling capacity of tailings slurry; significantly power generating ratio number of times, makes operating efficiency significantly at least improve 80%, extension device life cycle; and significantly reduce labour intensity, easily implement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is nozzle body upper end surface structure schematic diagram in Fig. 1;
In figure: 1-nozzle body, 2-inclined spray orifice, 3-Compress Spring, 4-pushing pearl, 5-middle font adapter, 6-nozzle connection, 7-injection hole.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing:
The nozzle of buildup in filling in mine mining vertical sand warehouse can be prevented, by nozzle body 1, the spray orifice 2 be located on nozzle body 1, the Compress Spring 3 be located in nozzle body 1, be placed in the pushing pearl 4 on Compress Spring 3 one top, withstand on pushing pearl 4 and be connected font adapter 5 with nozzle body 1, the nozzle connection 6 be connected with middle font adapter 5 forms, and it is provided with at least one injection hole 7 at the upper top end face of nozzle body 1; Spray orifice 2 on nozzle body 1 is inclined, and its angle of inclination is selected arbitrarily at 20 ~ 60 ° of degree.
During production, the spray orifice 2 on nozzle body 1 is owing to being inclined shape, and its spray angle becomes large, makes projected area enlarged relative; Again because the upper top end face at nozzle body 1 is processed with injection hole 7, also gas stirring is had to the vertical sand warehouse inwall of institute's opposite face from the stirring gas of its injection hole 7 ejection, therefore make tailings slurry fully can be stirred at vertical sand warehouse hypomere and discharge, buildup is significantly reduced.
It should be noted that the material higher for coefficient of elasticity that the Compress Spring 3 in this programme adopts; It is vitreous that pushing pearl 4 adopts.
This specific embodiment is only the best and exemplifies, the restricted enforcement not to technical solutions of the utility model.
Claims (2)
1. can prevent the nozzle of buildup in filling in mine mining vertical sand warehouse, by nozzle body, the spray orifice be located on nozzle body, the Compress Spring be located in nozzle body, be placed in the pushing pearl on Compress Spring one top, withstand on pushing pearl and be connected font with nozzle body and take over, take over middle font the nozzle connection be connected to form, it is characterized in that: be provided with at least one injection hole at the upper top end face of nozzle body; Spray orifice on nozzle body is inclined.
