Background technology
Chinese patent discloses a kind of dry-mixed mortar storage silo with isolation-proof device that application number is 200920063578.6, be provided with the cylinder that gathers materials that has some dumping pits on barrel in the central interior of silo, its upper end is connected with the top of silo body, and lower end is horn mouth and the middle and lower part that is positioned at silo body; Feed pipe upper end is connected perforation with the top of the cylinder that gathers materials, and stretch out outside silo body lower end, has at least connected a sub-feed tube on the feed pipe in silo, the other end with in the cylinder that gathers materials, bottom is connected and connects; In silo, be also provided with blast pipe, its upper end is positioned at the top of silo, and stretch out outside silo body its lower end.Chinese patent also discloses a kind of dry-mixing mortar storage tank with isolation-proof device that application number is 201020538553.X, its metal cone bucket has mainly adopted the design of hollow structure, on dry-mixing mortar storage tank feed opening top, a cone bucket body is installed, dry-mixed mortar segregation has been played to certain mitigation.Above-mentioned technology does not all fundamentally solve the segregation problem of dry-mixed mortar, the basic reason of dry-mixed mortar segregation is that the discharging opening of storage tank is in the foot centre of tank body, in the time of blowing, in storage tank, first material starts blanking from middle part, and V-type funnel-form of self-assembling formation, due to material particles particle diameter difference, angle of repose difference, the acceleration of gravity difference falling, the material that particle diameter is larger is walked first downwards, grain diameter compared with little along with large granular materials moves down and landing, thereby cause material to occur segregation.That is to say, the material segregation of different-grain diameter is because the material in storage tank produces in falling to moving, not only at charging or discharging opening.Simultaneously the segregation of dry-mixed mortar is a system problem, and not only at the scene in storage tank.
Summary of the invention
The purpose of this utility model is to provide a kind of device that prevents different-grain diameter granule materials segregation, and this device is made up of top cylinder, bottom cone, porous plate, ring holder, supporting traverse, brace rod, vibrator seat, arcuate socket and circular hole.In use, material is loose shape by feed hopper and spreading bucket and falls to entering in the cylinder of top, avoid material to pile up at top cylinder inner conical, material evenly falls by the circular hole in porous plate and arcuate socket again, avoid the difference due to material angle of repose, blanking is inhomogeneous, causes material size particles to separate, and produces segregation phenomenon.When piling up on porous plate when residual, existing vibrator is fixed on to vibrator seat, by the shock effect of vibrator, make to pile up on porous plate residue removal.It is fast that the utility model has overcome storage tank intermediate blanking, and the defect that periphery blanking is slow is guaranteed the even blanking of material in tank, there will not be because of granular size difference the different and material segregation phenomenon that causes in angle of repose.Have that anti-segregation is effective, the feature of uniform blanking, simple in structure, easily manufactured, long service life.
A kind of device that prevents different-grain diameter granule materials segregation described in the utility model, this device is made up of top cylinder, bottom cone, porous plate, ring holder, supporting traverse, brace rod, vibrator seat, fixed mount, feed hopper, spreading bucket, arcuate socket and circular hole, top cylinder (1) and bottom cone (9) connect as one composition storage tank, connecting portion in top cylinder (1) and bottom cone (9) is provided with porous plate (2), and fixed mount (12) is fixed on the top of top cylinder (1).
On porous plate (2), have impartial circular hole (3) and the arcuate socket (8) of arranging.
In fixed mount (12), fix up and down respectively feed hopper (10) and spreading bucket (11).
Connecting portion in storage tank internal upper part cylinder (1) and bottom cone (9) is fixed with ring holder (4).
On the bottom of storage tank cone (9) inwall, be fixed with brace rod (6), and be fixedly connected with supporting traverse (5) on brace rod (6).
Porous plate (2) is connected and fixed on ring holder (4) and supporting traverse (5).
Be connected and fixed vibrator seat (7) in the outer edge of porous plate (2).

The specific embodiment
The utility model further describes by reference to the accompanying drawings, and provides specific embodiment;
Embodiment:
As accompanying drawing 1,2, a kind of device that prevents different-grain diameter granule materials segregation described in the utility model, by top cylinder 1 and bottom cone 9 metal tank forming that is welded as a whole; Be fixed with all identical porous plates 2 of size and storage tank connecting portion shape and internal diameter at the connecting portion of storage tank internal upper part cylinder 1 and bottom cone 9, porous plate 2 is made up of metallic plate; On porous plate 2, have circular hole 3 and arcuate socket 8 that impartial diameter of arranging does not wait, centered by porous plate 2 centers of circle, radially distribute; Be fixed with fixed mount 12 on the top of top cylinder 1, at interior feed hopper 10 and the spreading bucket 11 fixed up and down respectively of fixed mount 12; Be welded with the ring holder 4 made from doughnut-shaped steel plate at the connecting portion of storage tank internal upper part cylinder 1 and bottom cone 9; On cone storage tank 9 inwalls of bottom, be fixed with brace rod 6, and be welded with metallic support crossbeam 5 on brace rod 6, the upper edge of ring holder 4 and supporting traverse 5, in same level, and is welded and fixed porous plate 2 on horizontal plane; Be connected and fixed vibrator seat 7 at the edge of porous plate 2, vibrator seat 7 extends to outside storage tank;
In use, material is loose shape by feed hopper 10 and spreading bucket 11 and falls to entering in top cylinder 1, avoid material to pile up at top cylinder 1 inner conical, material evenly falls by circular hole 3 and arcuate socket 8 in porous plate 2 again, avoid the difference due to material angle of repose, blanking is inhomogeneous, causes material size particles to separate, and produces segregation phenomenon.When piling up on porous plate 2 when residual, existing vibrator is fixed on to vibrator seat 7, by the shock effect of vibrator, make to pile up residue removal on porous plate 2.
The storage tank of the present embodiment is the combination of cylinder and cone, also can be designed to as required rectangular cylinder and cone and multiedge cylinder and cone.
