Purpose of the utility model is to solve bringing during pulp gravity flow in the prior art, one is provided
Kind structure is simple, cheap, can reduce the abrasion of ore slurry pipeline, the slow dress of ball mill gravity flow ore slurry pipeline convenient to carry out
It sets.
In order to achieve the above object, the utility model uses following technical scheme:
A kind of ball mill gravity flow ore slurry pipeline buffer unit, including baffle-box, the top of baffle-box is equipped with iron ore feeding hole, into mine
Mouth is connected with vertically into pipe road, and the lower part of baffle-box is connected with ore removal pipeline, and the lower part of baffle-box is equipped with manhole, manhole
On be removably connected with access panel, the inner sidewall upper portion of baffle-box is symmetrically arranged with two pieces of distribution grids diagonally downward, distribution grid
One end and the inner sidewall of baffle-box fix, the other end of distribution grid is hanging, and the inner sidewall lower tilt of baffle-box is equipped with support
Plate, one end of support plate and the inner sidewall of baffle-box are fixed, and the other end of support plate is fixed on the inner sidewall and buffering of baffle-box
The junction of bottom wall is removably connected with buffer layer in support plate.
Further, ore removal pipeline and vertically into the angle between pipe road be 135 °.
Further, the angle between support plate and horizontal plane is 15 ° -20 °.
Further, the angle between distribution grid and the inner sidewall of baffle-box is 15 ° -18 °, and between two distribution grid lower ends

Further, support plate is equipped with threaded hole, is provided with bolt hole on buffer layer, and support plate and buffer layer pass through
Stainless steel bolt connection.
The ball mill gravity flow ore slurry pipeline buffering apparatus of the utility model works as ore pulp with certain speed along vertically into pipe road
It feeds after baffle-box after the buffering of distribution grid again with abrasive rubber buffer layer contacts, is flowed out again by ore removal pipeline later,
Into next procedure.The utility model is weakening ore pulp itself by initial velocity and gravity bring energy, it can be achieved that reducing transport
The abrasion of pipeline ensures production process continuous and stable, reduces enterprise's production cost and maintenance personal's labor intensity.
The access panel of the utility model and the lower part of baffle-box are bolted.After the abrasion of abrasive rubber buffer layer
When needing replacing, dismantles access panel and replaced, reinstalled again after replacement.Using more convenient.
The angle of the utility model ore removal pipeline and vertical direction is 135 °, and long-term production practices show using 90 degree
It is easily worn on the outside of straight elbow, even if the service life uses also at 4-5 months, according to hydrodynamics continuity using wear-resistant material
Principle, the relationship between flow velocity and sectional area are v1s1=v2s2, and wherein v is the flow velocity of ore pulp in the duct, and s is ore slurry pipeline
Cross-sectional area, be inversely proportional by the cross-sectional area of the flow velocity in the duct of ore pulp known to formula and ore slurry pipeline, so when vertical
The cross-sectional area that ore removal pipeline is increased when being greater than 90 degree into the angle between pipe road and ore removal pipeline, connects according to hydrodynamics
Continue property principle it is found that when angle is gradually increased, the cross-sectional area of ore removal pipeline is gradually increased, flow velocity of the ore pulp in ore removal pipeline
It is gradually reduced, with the reduction of flow velocity, ore pulp gradually decreases the erosive wear of ore removal pipeline, but when angle increases to 135 degree
When ore removal pipeline cross-sectional area reach maximum, cross-sectional area is gradually reduced when being further continued for increasing, and flow rate of pulp is gradually increased.Cause
When this is vertically 135 degree into the angle between pipe road and ore removal pipeline, the cross-sectional area of ore removal pipeline is maximum, and flow rate of pulp is most
It is small, it is minimum to the erosive wear of ore removal pipeline, service life 2-3 months of ore removal pipeline can be extended according to live use experience.
Angle between the support plate and horizontal plane of the utility model is 15 ° -20 °.One comes it is possible to prevente effectively from baffle-box
Bottom causes to accumulate mine for a long time at dead angle, washes away impact into agglomeration by ore pulp, is not easily cleaned, two inclinations for carrying out buffer layer can drop
Low ore pulp washes away buffer layer, can reduce the abrasion of buffer layer abrasive rubber, while ensure that the effect of buffering, and prolongs
The service life of buffer layer is grown.
Angle between the distribution grid of the utility model and the inner sidewall of baffle-box is 15 ° -18 °, when ore pulp enters buffering
After case, first time buffering is carried out to ore pulp by distribution grid, when ore pulp passes through baffle-box with certain speed, distribution grid can subtract
Weak ore pulp makes ore pulp enter buffering lower box part with low velocity because of gravitional force bring kinetic energy, further decreases ore pulp to buffering
The abrasion of case and ore slurry pipeline extends the service life of buffer layer and ore slurry pipeline, and it is flat that guarantee continuous production stablizes the high period
Steady operation.And two the ratio of the spacing between distribution grid lower end and the spacing between two distribution grid upper ends be 3:5, in buffering ore pulp
While, it can effectively avoid ore pulp from being assembled and flow on buffer layer, buffer layer is locally caused to damage.
The support plate of the utility model is equipped with threaded hole, is provided with bolt hole on buffer layer, by bolt that buffer layer is tight
Gu on the supporting plate, and the thickness of support plate is enough namely the length of threaded hole is enough, the loosening of bolt not will cause.When slow
When rushing layer abrasion, it is convenient for changing.
