A kind of from bin row unload the device of the little bulk material of flowing power, its principal character is, has a center supply unit in bin, it only extends on the part of storehouse height, and preferably has the helical member of returned to the conveying of a central open.
Description
The present invention relates to the device that a kind of row unloads the little bulk material of flowing power, particularly row unloads the cotton stem of wood chip from wet condition to dried state, cutting blade, chopping from bin, and the device that contains lignocellulose or cellulosic granule materials, its bin the top feed and by the bottom particularly in the discharge port discharging at center, bin have one by motor driven with discharge port supply unit concentric and that extend on the height top of bin at least.
DE-OS 2624434 discloses a kind of type of device.This known device attempts to avoid the problem that causes owing to disadvantageous arch formation in the bin, has a helix transporting device that on the height of whole storehouse, extends in its storehouse at least and at least at its both sides and the auxiliary helix transporting device throughput direction adverse effect, the axis of its helix transporting device is positioned at and the perpendicular plane of the vertical sidewall in storehouse.When row unloads from the storehouse, because the materials flow of above-below direction forms the motion interlayer in vertical direction, this installation cost height, and be easy to occur functional fault, particularly after device is temporarily stopped using, must arrange and draw off crucial especially (kritische) material, as the cotton stem of quite wet wood chip, cutting blade or chopping, these materials are easy to form and tangle.
The purpose of this invention is to provide the quite device of compact described type of a kind of structure, this device can guarantee that row unloads continuously to scabrous especially and wet especially bulk material by avoiding forming disadvantageous arch formation in bin after work stops.
Purpose of the present invention is actually and reaches like this, its supply unit has one and unload the loosening transfer unit of the opposite conveying of direction with row in normal operation, it is configured in being in the infundibulate bottom of storehouse with one heart, and hopper walls has a segment distance relatively, and this flows to discharge port apart from the loose material materials flow that has guaranteed its side.
By of the combined action of loosening transfer unit with the wall guide face that particularly forms by funnel area, unload the cooperation that forms between the motion in loosening motion and row, make its bulk material loosening, particularly to the material of specific key, cotton stem as chopping has formed align (Ausrichtung) that row unloads material particles, thereby the row of making unloads smoothly and carries out.
Advantage of the present invention is; because of be positioned at above the infundibulate storehouse last storehouse (it also can be columnar in principle) until funnel area all enlarges, therefore can in the break over region that makes progress by loosening conveyor screw parts at the bulk material of center conveying, be formed for the turnover of bulk material and the particle that moves downward from sidewall with return enough spaces that particle mixes.
Another advantage of the present invention is, the loosening transfer unit of supply unit is connected with driver element by axle drive shaft, the development length of axle drive shaft that originates in bin lid is at least greater than half of last storehouse height, make loosening process be limited to funnel area and given subregion, last storehouse, promptly, only owing to need to obtain continuously place that row unloads and produce and stirring, therefore the bulk material in last storehouse is only by gravity rather than pass through power and move, thereby saved energy significantly.
Another substantial being characterized as of the present invention, loosening transfer unit is formed at the helical member of central open by one, and particularly its material feeding end is connected with axle drive shaft by a span tackle arrangement.
Adopt the helical member of central open to obtain and axially return conveying to what loosening bulk material had a very good effect, because can form the backflow that is extruded in the unlimited central region of helical member, the row that can not hinder in its side that refluxes unloads stream.In addition, return in the transfer movement process, positive interaction is exerted an influence to rectangular materials at the center.It helps to arrange and draws off those crucial especially materials.
Of the present invention another is characterized as, and the distance of the relative discharge port of free end of loosening conveyor screw parts is adjustable.Can in bin, store different materials like this.In view of the above, unloading the cross section discharge port row on every side can change by adjustable screw spare.Helix transporting device is common than carrying the not too crucial more close discharge port of material when carrying crucial especially material.
Structure and feature that other is favourable provide in the dependent claims.
Below with reference to accompanying drawings embodiments of the invention are further described.
Unique accompanying drawing is the scheme drawing of apparatus of the present invention, and this device is specially adapted to the cotton stem of wood chip, cutting blade and the chopping that will discharge continuously from bin.
Last storehouse can be columnar, but preferably as shown in FIG. its cross section 3 is slightly enlarged shape from the upper end to the funnel shaped part, makes that the transition region between two storehouses 2 and 3 forms the maximum cross-section.
Have a material inlet 4 on the lid 17 of bin 1, necessary words can be provided with a porthole covering also.
In the embodiment shown, lid 17 is formed for driver element 7 simultaneously, and the support that is used for the supply unit 6 that connects with driver element 7, and described driver element 7 comprises the motor that the driving device with insertion connects together.
Originate in cover 17 axle drive shaft 8 development length at least greater than half of last storehouse 2 height, and loosening transfer unit 9 is connected with axle drive shaft 8 and extend to discharge port 5 near.
In fact, the development length of loosening transfer unit 9 is not more than the whole height of bin 1, this mode makes near the bulk material axle drive shaft 8 can not stir by conveyor screw spare, be in static on the contrary, this in fact saved energy and also carry smooth because can flow and can not produce arch formation at this zone bulk material.
Loosening conveyor screw parts 9 are preferably the helical member of central open, return delivery area 10 so that form one in the outline of helical member, and the bulk material in will distinguishing when helical member rotates is upwards carried, so that can form the backflow of extruding in bin 1.So just can on the whole cross section of bin 1, not produce bigger interference range, unload the required cross section 11 of conveying thereby guaranteed have bigger being used to arrange.
The gradient of helical element 9, promptly the gradient of the relative horizontal surface of conveyor screw face of helical element 9 can be selected according to convey materials, and its optimum value is 45 °, for different bulk materials one different optimum value should be arranged.The present invention is not limited to size and describes.
The cross section of helical member is the most smaller like the cross section of discharge port 5, relative size between helical element 9 and the infundibulate storehouse 3 is to select like this, so that the feed back that is extruded is always placed in the middle, and provide enough big row to unload at sidewall to carry the cross section, so that in funnel area, overturn serially and arrange and unload conveying.
When helical element 9 normal operation, return conveying in order to form bulk material, helical member is counter-rotation at least at short notice, more properly be that it is worked in the above described manner, because after long-time static, formed curing or produced caking phenomenon in funnel area, unclamped undesirable compacting by changing hand of rotation repeatedly at short notice in this case, then arranged normally again and unload conveying.
The free end of helical element 9 discharge port 5 is relatively regulated, promptly near it or away from it.This just can match with the material that unloads of row at that time, if handled at that time material fluidity diminishes gradually, the end of conveyor screw parts 9 is just more and more nearer with discharge port 5 so, according to loosening effect of requirement, and its end even can always extend to discharge port 5.
The axial adjustment of helical element 9 on the principle can by one that be fit to, finish from the mechanic adjustment unit of peripheral operation, this control apparatus preferably simple in structure being difficult for break down, as shown in the figure.
The material feeding end of helical element 9 is fixed on the span tackle arrangement 12, exactly is fixing by annual spring tension element 13, and element 13 comprises two span coasters that are contained on the axle drive shaft 8.The position of these span tackle arrangement 12 relative drive shafts 8 determined by screw rod 14, and screw rod is at span tackle arrangement 12 and be fixed in and extend between the back plate 16 of axle drive shaft 8 ends and fixing by the relative back plate of jam nut 16.
Can change the setting range 15 of helical element 9 by adjusting screw(rod) 14, this setting range 15 should be enough to satisfy all requirements that occur in the real work.
The row that promptly can control discontinuously from bin again continuously by device of the present invention unloads, loosening conveyor screw parts 9 must rotate relatively slowly, to guarantee that desirable row unloads, for example the revolution of helical element 9 can be between 20 rev/mins to 40 rev/mins, but are not limited thereto.
Another advantage of unlimited helical member of the present invention is to have few relatively axial tensile force in supply unit 6, and desired intensity size is produced favourable influence.This is the result that open design produces.
