The device has the advantages of no need of motive power, energy saving, simple structure, low cost, convenient use and good effect.

Description

Unpowered hump-truncated diversion device

The present invention relates to the device that a kind of solid material self gravitation is discharged from container continuously, the device that the solid material that the easy knot arch of flowing power difference is loosed core can be discharged by self gravitation continuously from container.

At present, the knot that is produced when solid material is drawn off from container encircles the phenomenon of loosing core, and carries out with following apparatus and method:

1, chain arch breaking apparatus: a vertical axle is housed in the middle of device, fixes several chains around it, during discharging, axle is rotation rapidly under engine drives, and chain opens, and hits material, makes it to flow to discharge port and discharges.

2, the broken arch of auger removal device: have three kinds of forms 1. in the middle of hopper, to adorn an auger, drive auger by decelerator during discharge, reach brokenly the purpose of arch discharge; 2. parcey discharger; 3. E.C.R.Denis discharging conveying system.(2. and bibliography 3. be: French Marshall father and son of research institute of scientific-technical information of Ministry of Food translation " pressure and over pressure when silo, the second volume discharging " and industrial 83 years the 3rd phases " sweeping the calculating of storehouse auger principal parameter " of grain).

3, vibrator: at feed opening other peace one machinery and electromagnetic shaker, the vibration bottom hopper is transmitted amplitude by material simultaneously during discharging, destroys material balance, and material is discharged.

4, air helps the stream method: adopt the pneumatics that is formulated in the bottom, storehouse to blow into air, make material form fluidization and easily outflow, (seeing " grain 81 years the 3rd phases of industry ").

5, many mouthfuls of discharging methods: several discharging openings are established at (container) end in the storehouse, when material forms knot arch and looses core in the storehouse, open other discharge port during discharging, to destroy the stress that the material knot arch that forms looses core and to continue discharge.

Above-mentioned the deficiencies in the prior art part is: what have needs power, consumes energy; The complex structure that has, troublesome poeration influences production efficiency; The practical function that has is not good; The cost that has is too high.

The objective of the invention is to avoid above-mentioned the deficiencies in the prior art part and provide a kind of and need not power, save the energy, simple in structure, easy to use, effective, unpowered hump-truncated diversion device that cost is low.

The technical measures of taking for achieving the above object are:

On top is barrel, in the container that the bottom is connected as a single entity for the infundibulate hopper, it is identical to support the bottom surface diameter, two bottom surfaces link to each other, the bicone of forming by upper cone and lower cone that two vertex of a cones are opposing, the kinetic pressure and the wedge power at the awl bucket end that produce when being used to bear most static pressures of material and discharging; Being supported on the axis of bicone in the container and the axis (line of centers) of container coincides; The relation of facies basialis pyramidis diameter and container barrel diameter is: the facies basialis pyramidis diameter is less than container barrel diameter, greater than 3/4 of barrel diameter; The vertex of a cone of lower cone cuts the tip, and the cross section is parallel with the bicone bottom surface; Strut bar between the hopper of lower cone and container bottom is 3～8, is preferably 3～4, so that make transmission of pressure that bicone bears to the bucket wall of container bottom; The angle α of upper cone bus and facies basialis pyramidis ₁Should guarantee that material is under conical flow, promptly ^lG α ₁＞f ₁, f ₁Be the friction coefficient of material, the angle α of lower cone bus and facies basialis pyramidis ₂Angle according to the container hopper is decided with the maximum particle size of unloading material; The angle α of lower cone bus and container hopper bus ₂With cylindrical shell and the crossing angle α of hopper ₃The pass be α ₂=α ₃, or α ₂＞α ₃, its differential seat angle is no more than 15 degree, and is higher to shell, as height during greater than 3 meters, be more than facies basialis pyramidis, and on the following material tube inner wall of the upper cone vertex of a cone downward-sloping deflecting plate is housed, to avoid the top material blanking channel is produced direct pressure.

Accompanying drawing is a face portion view of the present invention.

Below in conjunction with accompanying drawing structure of the present invention and worker and principle are described in further detail:

As shown in drawings, in the container that is connected as a single entity by barrel 3 and hopper 4, it is identical to support the facies basialis pyramidis diameter with strut bar 6, facies basialis pyramidis joins, the bicone that upper cone 1 that the vertex of a cone is opposing and lower cone 2 are formed, the axis C-E of bicone and the container axis F-G that is connected as a single entity by cylindrical shell 3 and hopper 4 coincide, the relation of the diameter D of facies basialis pyramidis diameter d and barrel 3: d＞3/4D, d＜D; Lower cone 2 cuts the vertex of a cone and sealing, and front cover parallels with facies basialis pyramidis.The wall upper support that is welded on lower cone 2 and hopper 4 with 3 isometric strut bars 6 bicone, the angle α of upper cone bus a-h and facies basialis pyramidis ₁For ^lG α ₁＞5,5 is the material friction coefficient, the bus a-h of lower cone 2 and the angle α of facies basialis pyramidis ₂With 3 bus i-j at the bottom of the cylindrical shell and the angle α of hopper 4 intersection line i-a ₃The pass be: α ₂=α ₃Or α ₂＜α ₃, its differential seat angle is no more than 15 degree, more than the a-b of upper cone bottom surface, is welded with downward-sloping minute pressing plate 7 in the inwall of the barrel 3 that vertex of a cone E point is following.

Structure from above as can be known, kinetic pressure that produces when most static pressures of material and discharging and wedge power, be to bear and be delivered to by strut bar 6 on the wall of hopper 4 by cone, material is discharged from discharge port 5 along the passage that barrel enters between lower cone 2 male cone (strobilus masculinus)s and the hopper 4 internal conflict faces on every side.Because the combined action that the destruction of 1 pair of material stress of upper cone and the material in the blanking channel directly do not bear the top material pressure can guarantee that material is able to smooth discharge by self gravitation.

The material of this device is metal, as carbon steel, aluminum alloy, corrosion-resistant steel etc., also can be engineering plastics, pottery.

The present invention compared with prior art has the following advantages:

1, do not need power, save the energy;

2, simple in structure, easy manufacturing is with low cost; The cost of one table apparatus only needs hundreds of unit, and other broken arch mechanism, needs several thousand yuan from buying installation, many reaches units up to ten thousand.

3, can guarantee the homogeneity of effluent material granularity quality: since the structures shape of this device during discharge, material descends around bulkhead, the material face becomes horizontality to descend basically in the barrel, can avoid material when discharging, to produce automatic classification and other device all can make material form funnel-form in the storehouse and automatic classification phenomenon is serious, influence the material shop characteristic.
