Description
Technical field
This utility model relates to Ore polish field, specifically refers to a kind of reducing mechanism for barite.
Background technology
Barite belongs to non-renewable resources, is one of Chinese trump-cards in the export of mineral products, is widely used in oil, the heavy weight additive of natural gas drilling mud, and the consumption figure in fields such as barium chemical industry, fillers is also increasing year by year.China's barite resources is the abundantest, is distributed in 21 provinces in the whole nation, 3.6 hundred million tons of total reserves Ore, occupies the 1st, the world.Medically can be used for contrast agent in digestive system.
During actually used, generally use disintegrating machine to realize barite to pulverize to form barite raw material, but in prior art, the pulverizing of barite particle is easy to occur that granular size differs, and coarse fodder is difficult with the collection of fines, needing the most further to be screened, crushing efficiency is low and causes production cost and labour cost higher.
Utility model content
The purpose of this utility model is to provide a kind of reducing mechanism for barite, to overcome the problems referred to above.
The purpose of this utility model is achieved through the following technical solutions:
A kind of reducing mechanism for barite, including the pulverizing cavity being interconnected and sieve material pipe, the isolated chambers of annular it is fixed with in described pulverizing cavity, described isolated chambers and pulverizing cavity annular space, multiple support column it is vertically arranged with in isolated chambers, rotate on support column and be provided with outer shaft, multiple cutting sheet it is hinged with on outer shaft, pulverizing chamber outer wall offers the air outlet connected with described annular space, the wind pushing hole corresponding with air outlet it is provided with in described isolated chambers, the axes intersect of the axis of described wind pushing hole and described isolated chambers and out of plumb, also include drainage conduit and hopper, described hopper connects with isolated chambers, described drainage conduit one end is run through the middle part of pulverizing cavity and extends outside sieve material pipe, the drainage conduit other end extends outside pulverizing cavity and is provided with at this end and deflects from blower fan；Being connected with one end of passage by outlet valve at described drainage conduit end, the other end of passage connects with hopper, and is provided with traction blower fan on passage.
During utility model works, in annular space, swiftly flowing gas is injected by air outlet, after gas is by doing certain circular motion in annular space, entered in isolated chambers by wind pushing hole, due to the axis of wind pushing hole and the axes intersect of isolated chambers but out of plumb, i.e. wind pushing hole is obliquely installed, and constantly enters into the gas in isolated chambers and forms eddy flow；Now the barite particle after first grinding enters in isolated chambers by hopper, granule mixes with eddy flow, make mutually to collide between the granule of different size size, under the influence of active force with counteracting force, partial particulate is launched to isolated chambers inwall after collision occurs, and is re-introduced in eddy flow through reflection, i.e. carries out collision repeatedly, make larger-diameter granule gradually become fine particle, eventually form superfines；And along with the movement of eddy flow, the bigger granule of section diameter is under its action of gravity, the granule of this part directly drops to the end of drainage conduit, and ultra-fine powder is then discharged by drainage conduit upper end under the absorption deflecting from blower fan is drawn, and then realizes the extra-fine grinding operation of barite.When barite particle collides with granule, air-flow velocity in wind pushing hole is relatively big, and wind pushing hole is obliquely installed simultaneously so that barite particle is difficult to enter in annular space by wind pushing hole, avoid gas moving formation eddy flow and causing obstruction, improve the crushing efficiency of barite particle.
Wherein, under the effect of eddy flow, the outer shaft on support column can be driven to rotate, and then drive cutting sheet to rotate, so, bigger barite particle can be cut；Meanwhile, eddy flow also can make granule directly impinge upon on outer shaft, and turns to outer shaft into row stochastic restriction, so, can constantly change turning to of cutting sheet, to strengthen the crushing effect to granule.When the tenesmus of part larger particles is to drainage conduit end, open outlet valve, bigger granule is re-moved to hopper by passage under the drive of traction blower fan, broken with carry out again, and then form the circulation line that a barite particle crushes repeatedly, i.e. ensure that the diameter of the barite particle discharged by discharge nozzle upper end reaches ultra-fine standard, improve the super fine crushing efficiency of barite further.
Further, the end internal diameter of described sieve material pipe successively decreases downwards along its axis.Larger-diameter granule also suffers from the Effect of Rotation of eddy flow when tenesmus and continues to collide with sieve material inside pipe wall, i.e. constantly rebound on sieve material inside pipe wall, and be arranged to successively decrease downwards along its axis by the end internal diameter of sieve material pipe, reducing is formed at sieve material pipe end, reduce the rebound rate of major diameter granule, accelerate the collection of major diameter granule.
Further, also including feed pipe, described hopper is connected with described isolated chambers by feed pipe.So, the charging of barite particle in isolated chambers can be avoided uneven, and then prevent from reducing crushing efficiency.
Further, the blast pipe connected with described feed pipe is also included.In feed pipe, injected the pusher air-flow of auxiliary by blast pipe, blocking occurs in can preventing feed pipe, accelerates the collision frequency between isolated chambers endoparticle and granule simultaneously, improve the super fine crushing efficiency of barite further.
This utility model compared with prior art, has such advantages as and beneficial effect:
1, this utility model is when barite particle collides with granule, air-flow velocity in wind pushing hole is bigger, wind pushing hole is obliquely installed simultaneously, barite particle is made to be difficult to enter in annular space by wind pushing hole, avoid gas moving formation eddy flow and causing obstruction, improve the crushing efficiency of barite particle.
2, the end internal diameter of sieve material pipe is arranged to successively decrease downwards along its axis by this utility model, forms reducing at sieve material pipe end, reduces the rebound rate of major diameter granule, accelerate the collection of major diameter granule.
3, during this utility model application, under the effect of eddy flow, the cutting sheet being arranged on outer shaft can be driven to rotate, so, bigger barite particle can be cut；Meanwhile, eddy flow also can make granule directly impinge upon on outer shaft, and constantly change cutting sheet turn to strengthen crushing effect to granule.
4, hopper is connected with isolated chambers by feed pipe, so, the charging of barite particle in isolated chambers can be avoided uneven, and then prevent reduction crushing efficiency.
5, in feed pipe, injected the pusher air-flow of auxiliary by blast pipe, in feed pipe can be prevented, blocking occurs；Meanwhile, accelerate the collision frequency between isolated chambers endoparticle and granule, improve the super fine crushing efficiency of barite further.
6, during this utility model application, bigger granule is re-moved to hopper by passage under the drive of traction blower fan, broken with carry out again, and then form the circulation line that a barite particle crushes repeatedly, i.e. ensure that the diameter of the barite particle discharged by discharge nozzle upper end reaches ultra-fine standard, improve the super fine crushing efficiency of barite further.
