Description
Technical field
The invention belongs to preparation equipment technical fields, and in particular to a kind of ore pulp pan feeding equipartition device.
Background technology
For the preparation equipment using certain density ore pulp as pan feeding, need that ore pulp is imported into equipment by feeding pipe
It is interior, such as separation of coarse slime machine（TCS、TBS）, this kind of equipment is to reach the effect of material dispersion by way of Swirl pan feeding
Fruit, but this pan feeding mode there are pan feeding is uneven or pan feeding in pipeline medium velocity more slowly there is a phenomenon where depositing, it is this enter
Material mode leads to central area and fringe region granularity and concentration distribution unevenness in equipment, causes the product bed of material and sedimentation bed of material hair
Raw interference, inside can not form stable ore pulp fluidised form, increase system operatio difficulty, reduce sharpness of separation and the efficiency of separation.
Invention content
The technical problem to be solved by the present invention is to for the existing preparation equipment using certain density ore pulp as pan feeding
Pan feeding mode above shortcomings, provide a kind of ore pulp pan feeding equipartition device, which may be implemented ore pulp and uniformly feed
In equipment, and the identical direction of motion, pressure and flow velocity are kept, to ensure that the pan feeding uniformity of ore pulp, improved such
The sharpness of separation and the efficiency of separation of preparation equipment.
Used technical solution is the present invention to solve above-mentioned technical problem：
A kind of ore pulp pan feeding equipartition device, it is characterized in that it is emitted by feeding pipe, branch pipe, umbrella, umbrella emits support and center discharge nozzle group
At feeding pipe is the steel pipe of thick diameter, and branch pipe is the steel pipe of thin diameter, and branch pipe is connected to feeding pipe, and manifold configuration is identical, quantity
At least two, and be evenly arranged centered on feeding pipe vertical segment, branch outlet is in same level and keeps outlet upward,
Umbrella emits the beveled structure that certain cone angle is surrounded using steel plate, and emitting surface in umbrella is uniformly distributed several through-holes, and umbrella is emitted emits branch by umbrella
Support is connected with branch pipe, and setting center discharge nozzle and umbrella emit at the top of feeding pipe vertical segment, the level that center discharge nozzle exports and umbrella emits
The corresponding position that height and branch outlet and umbrella emit is highly consistent.
By said program, the center pipe diameter that discharges is more than branch pipe diameter, it is ensured that the flow rate of pulp of center discharge nozzle outlet with
The flow rate of pulp of branch outlet is consistent.
Preferably, feeding pipe is " L " shape structure, is fed ore pulp in equipment from outside by horizontal segment, vertical segment and is set
Standby central shaft is aligned or approaches, and horizontal segment sets certain slope, and the set gradient is determined according to pulp density and flow velocity, and set slope
Degree is positive value, and purpose is to prevent ore pulp from being deposited in feeding pipe.
Preferably, branch pipe be " L " shape structure, vertical segment is vertically upward, it is ensured that stream direction vertically upward, horizontal segment
If certain slope, the set gradient is determined according to pulp density and flow velocity, and the set gradient is positive value, and purpose is to prevent ore pulp from existing
Deposition in branch pipe.
Preferably, umbrella emits support and is made of three round steel, not only can guarantee the stability that umbrella emits, but also can expand mine as far as possible
Starch the space of outflow.
Preferably, the cone angle that umbrella emits is designed by 90 °~150 °.
The present invention brings following advantageous effect：
Ore pulp reaches branch pipe and center discharge nozzle by feeding pipe, and fortune vertically upward is realized by branch pipe and center discharge nozzle
Dynamic, most of ore pulp changes direction of motion realization and moves downward after encountering umbrella and emitting.Since manifold configuration is identical and uniform
It is arranged in feeding pipe surrounding, the ore pulp pressure at manifold inlet is identical, and the branch pipe resistance of ducting is identical, so the ore pulp of branch outlet
Flow velocity is identical with pressure.Center discharges pipe diameter more than branch pipe diameter, it is ensured that center discharge nozzle and branch pipe discharging speed phase
Together.The purpose that umbrella emits trepanning is to reduce the downward speed of ore pulp to reduce branch outlet ore pulp pressure.It can ensure in this way
Section pan feeding ore pulp is uniformly distributed at material, improves equipment sharpness of separation and the efficiency of separation.
Above-mentioned apparatus may be implemented pan feeding ore pulp and be uniformly distributed, and flow field is made more to stablize, and ore pulp only needs a feeding mouth, knot
It is simpler on structure, it is convenient for installation and maintenance, it is easy to control, sharpness of separation and the efficiency of separation are improved, energy consumption is reduced, is solved
It has determined problem of the existing technology.
Description of the drawings
Fig. 1 is the sectional view of the present invention.
Fig. 2 is the vertical view of the present invention.
In figure：1- umbrellas emit；2- umbrellas emit support；3- branch pipes；4- feeding pipes；The centers 5- discharge nozzle.
Specific implementation mode
The present invention will be further described below in conjunction with the accompanying drawings, but they are not the limit to the scope of the present invention
It is fixed.
As depicted in figs. 1 and 2, the ore pulp pan feeding equipartition device in the present embodiment, including feeding pipe 4, branch pipe 3, umbrella emit 1,
Umbrella emits support 2 and center discharge nozzle 5.Feeding pipe 4 is the steel pipe of thick diameter, and branch pipe 3 is the steel pipe of thin diameter, branch pipe 3 and pan feeding
Pipe 4 is connected to, and 3 structure of branch pipe is identical, and quantity is 4, and is evenly arranged centered on 4 vertical section axis of feeding pipe, and branch pipe 3 exports
In same level and keep outlet upward, umbrella emits 1 beveled structure for surrounding certain cone angle using steel plate, and it is uniform to emit surface in umbrella
Several through-holes are distributed, umbrella, which emits to emit by umbrella, supports 2 to be connected with branch pipe 3, and center discharge nozzle 5 is provided at the top of 4 vertical segment of feeding pipe
Emit 1 with umbrella, the outlet of center discharge nozzle 5 and umbrella emit 1 level height and the outlet of branch pipe 3 and umbrella emit 1 corresponding position it is highly consistent.
Arrow in Fig. 1 and Fig. 2 indicates that ore pulp flow direction, ore pulp enter vertical segment by the horizontal segment of feeding pipe 4
In, due to identical with 4 interface pressure of feeding pipe in branch pipe 3,3 structure of branch pipe is identical with ore pulp flow resistance, so ore pulp is logical
The speed for crossing branch pipe 3 is identical with pressure, and ore pulp surrounding in equipment may be implemented and be uniformly distributed, feeding pipe 4 vertical segment top
It is provided with center discharge nozzle 5 and umbrella emits 1, the white space that center is distributed without ore pulp can be filled up, to realize ore pulp in section
On be uniformly distributed, emitted due to being provided with umbrella above branch pipe 3 outlet end, when the ore pulp with certain speed encounters umbrella and emits inner wall
Change the direction of motion, ore pulp is changed to scatter out downwards straight up by original, to achieve the effect that dispersion, umbrella emit on 1
Hole be the speed after ore pulp reflection to be reduced, in order to reduce the pressure of ore pulp to improve ore pulp in the steady of equipment interior flow field
It is qualitative.
According to the disclosure and teachings of the above specification, those skilled in the art can also become above-mentioned technical proposal
More and change.But the invention is not limited in above-mentioned specific technical solutions, every those skilled in the art are the present invention's
On the basis of made any conspicuously improved, replacement or modification all belong to the scope of protection of the present invention.In addition, although originally
