Description
Technical field
The utility model relates to a kind of underground filling pipeline equipment, is exactly that a kind of underground filling pipeline is wear-resisting curved specifically
Head unit.
Background technology
At present, the transfer pipeline elbow of down-hole drilling tailings slurry uses ceramic composite pipe or bimetal tube,
Require higher local many employing Backpack type wear-resistant bends to wear-resisting, but owing to underground filling elbow is very big by charges
Impact, and last mortar flow velocity is too fast, causes the elbow life-span low, and fragile, impact is normal to be produced, grinding of traditional wear-resistant bend
Studying carefully direction is more conversion materials, increases wall thickness, but cost needed for the direction is high, and the R&D cycle is long, and, when stowing gradient is too small,
Typically can affect the conveying of last mortar.
Content of the invention
The utility model is for deficiency of the prior art, it is therefore an objective to provide one reduce last mortar flow velocity and impulsive force,
The low underground filling elbow of pipeline device of wear-resisting, production cost.
The technical scheme that the above-mentioned technical problem of the utility model solution is used is:
A kind of underground filling pipeline wear-resistant bend device, including sand-feeding tube, transhipment pipe, elbow and outer tube, sand-feeding tube lower end
Being connected with transhipment pipe upper end and communicating, transhipment pipe top arranges block ring, can arrange multiple block ring, and transhipment side, pipe bottom is arranged
Sand removing hole, in the middle part of transhipment pipe, side is connected with elbow left end and communicates, and arranges lining, the shape in a tubular form and with elbow for the lining in elbow
Shape is corresponding, and elbow right-hand member is connected with outer tube, arranges inner tube in outer tube, and elbow right-hand member is connected with inner tube and communicates, the diameter of inner tube
Less than the diameter of elbow, the diameter of outer tube is identical with the diameter of elbow.
The material of above-mentioned lining is polyurethane rubber.
Above-mentioned sand-feeding tube, transhipment tubing matter are abrasion-resistant metal pipe.
Above-mentioned elbow, outer tube, inner tube material are antiwear composite ceramic.
Above-mentioned outer tube, inner tube length are all higher than 4 meters.
The utility model has the beneficial effect that
Compared with prior art, the utility model is by arranging block ring on transhipment pipe top, it is possible to decrease the stream of last mortar
Speed, the impulsive force reducing last mortar；The tailings heap of transhipment pipe bottom deposition, the last mortar constant impingement tailings heap falling after making,
Produce the effect of sand milling sand, reduce the flow velocity of last mortar, the impulsive force reducing last mortar further；The lining arranging in elbow can
Weakening last mortar to the impact of elbow and abrasion, improving the service life of elbow, inner tube diameter, less than the caliber of elbow, increases
The local resistance loss of pipeline, had both reduced the flow velocity of last mortar, reduces impact and the abrasion of inner tube, can guarantee that again last mortar
In the flowing of inner tube full packages, reduce the too small adverse effect to last mortar conveying of stowing gradient.Sand removing hole can clear out of part tailings
Heap, it is ensured that the conveying of last mortar is unimpeded.The utility model simple in construction, facilitates durable.
Brief description
The following drawings is only intended in making schematic description and interpretation to the utility model, however it is not limited to of the present utility model
Scope.Wherein,
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to technical characteristic of the present utility model, purpose, effect and embodiment are more clearly understood from, in conjunction with
Brief description detailed description of the invention of the present utility model.
As it is shown in figure 1, a kind of underground filling pipeline wear-resistant bend device, including the 1st, sand-feeding tube transport pipe the 2nd, elbow 3 and outward
Pipe 4, sand-feeding tube 1 lower end is connected communicates with transhipment pipe 2 upper end, transports pipe 2 top and arranges block ring 9, can arrange multiple block ring
9, transhipment side, pipe 2 bottom arranges sand removing hole 7, and in the middle part of transhipment pipe 2, side is connected with elbow 3 left end and communicates, and setting in elbow 3 serves as a contrast
In 8, in a tubular form and corresponding with the shape of elbow 3, elbow 3 right-hand member is connected lining 8 with outer tube 4, arranges inner tube 5 in outer tube 4, curved
3 right-hand members are connected with inner tube 5 and communicate, the diameter of inner tube 5 less than the diameter of elbow 3, the diameter phase of the diameter of outer tube 4 and elbow 3
With.
The utility model specifically operates as follows, and sand-feeding tube 1 is vertically installed in boring, and transhipment pipe 2 is vertically pacified
Being contained on the base plate in tunnel, elbow the 3rd, outer tube the 4th, inner tube 5 is along roadway layout, when the last mortar on ground is by boring pipeline high velocity stream
During to foot of hole, being fallen in transhipment pipe 2 by sand-feeding tube 1, the block ring 9 that transhipment pipe 2 top is arranged can reduce the stream of last mortar
Speed, the impulsive force reducing last mortar, the last mortar falling at first is deposited as tailings heap 6 in transhipment pipe 2 bottom, after the tailings that falls
Slurry constant impingement tailings heap 6, makes to be washed in the middle part of tailings heap 6 circular cone cavity, produces the effect of sand milling sand, the existence of tailings heap 6
Further reducing the flow velocity of last mortar, the impulsive force reducing last mortar, the last mortar having impacted tailings heap 6 flows back up
To elbow 3, the lining 8 that arranges in elbow 3 can weaken last mortar to the impact of elbow 3 and abrasion, improves the use longevity of elbow 3
Life, flows through the last mortar of elbow 3 inner tube 5 in tunnel and carries, and owing to caliber attenuates, the local resistance increasing pipeline is damaged
Lose, both reduced the flow velocity of last mortar, and reduced impact and the abrasion of inner tube 5, and can guarantee that again last mortar at inner tube 5 full-section pipe-flow
Dynamic, reduce the too small adverse effect to last mortar conveying of stowing gradient.When the tailings heap 6 of transhipment pipe 2 bottom deposition is more, impact
During the conveying of last mortar, open sand removing hole 7 and clear out of part tailings heap 6, it is ensured that the conveying of last mortar is unimpeded.
In such scheme, the material of lining 8 is polyurethane rubber, and anti-wear performance is good.
In such scheme, the 1st, sand-feeding tube is transported pipe 2 material and is abrasion-resistant metal pipe.
In such scheme, elbow the 3rd, outer tube the 4th, inner tube 5 material is antiwear composite ceramic.
In such scheme, outer tube the 4th, inner tube 5 length is all higher than 4 meters.
The foregoing is only the schematic detailed description of the invention of the utility model, be not limited to model of the present utility model
Enclose.Any those skilled in the art, the equivalent variations made on the premise of without departing from design of the present utility model and principle,
Modification and combination, without departing from spirit of the present utility model, all should belong to the scope of the utility model protection.
