Description

Turntable type quantitative discharging device
Technical field
The utility model relates to a kind of feedway, and especially powder, particulate matter quantitatively goes out pay-off.
Background technology
In the production of feedstuff industry, raw material is processed into feed product, generally need through five basic production operations, that is: raw material pulverizing → powder, mineral matter and medicine material batching → mixing → granulation → packing → finished product.Because of mineral matter, medicine production process consumption are few, kind is many, and its blending process is commonly referred to as micro-ingredients.Below identical abbreviation---micro-ingredients.
China's feed industry is through nearly 20 years development, and manufacturing scale and output have great variety.According to the communique data of " Chinese feed industry Information Network ", by 2008, feed gross annual output amount surpassed 100,000,000 tons, and all kinds of production of fodder factory sum reaches 15000 families.But in numerous production of fodder producers, most " micro-ingredients " production processes is at present still substantially by manually finishing.Because there are defectives such as labor intensive is many, weighting error is big in artificial trace batching, and quality problems such as mismatch material taking place easily, so become the bottleneck of feed production technology naturally, also is the current big technical barrier for the treatment of with solution of current home and abroad feedstuff industry.
Micro-ingredients automation difficult point and reason thereof:
Production of fodder is undertaken by batch mode, batch products of every production, and the micro material of required proportioning has that kind is many, consumption is greatly different, physical and chemical performance difference is big, and its otherness mainly shows following three aspects:
1) breed difference: several at least, tens kinds at most;
2) weight differential: each material consumption: 0.01~50kg does not wait;
3) materialization difference (being Powdered):
Flowing power: 5 °~80 ° of slope angle of reposes;
Unit weight: 300~2000kg/ cubic meter;
Fineness: 40~250 orders;
Hygroscopic property: ambient humidity 〉=70%, raw material is as contacting with air, the easy moisture absorption of short time, and its flowing power variation easily produces clustering phenomena.
Therefore, realize compounding automation and satisfy manufacturing technique requirent that employed discharging proportioner must possess following basic feature:
1) can in storage container, take out material smoothly;
2) it is big to adapt to the load scope: 0.01~25kg, and the fast requirement of speed;
3) load precision height: 0.001~0.005kg (scale division value);
4) discharging equipment is easy to use, and cleaning is simple;
5) every kind of raw material should have independently drawing mechanism, prevents to store the mutual union dyeing of raw material.
More than 5 basic demands be to sum up the conclusion that draws from production practice.At present existing various types of automatic recipe maker, so the characteristic of " discharging smoothly, accurately discharging, discharging speed are fast " owing to fail to possess simultaneously is rare inputs reality use in the production of fodder at home.
The discharge method of existing all kinds of automatic recipe makers or system has at present: " upset of material bailing bucket ", " vibration discharging ", " spiral discharging formula " etc. are several.Wherein with spiral discharging formula type for seeing more, existing is example with " spiral discharging " device (Fig. 1), it is as follows to analyze its performance deficiency:
1, discharging speed and precision can not be taken into account: if screw diameter is big, then discharging speed is fast but precision is not high; Otherwise spiral shell footpath is little, and the discharging sectional area is also little, discharging precision height and speed is unhappy.
2, it is poor to adapt to material: when doing discharging with screw, to the powder of good fluidity, as the calcium hydrogen phosphate of mineral matter class etc., material is easily let out discharging opening by propeller blade; Otherwise, if the material of flowing power difference, easily produce ramming material arch in the container and can not discharge as starch-containing medicine class, milk powder class etc.; Or raw material is because of being subjected to screw in compression and agglomerate occurs or sticking on the paddle.
3, use inconvenient: if because of the bin stock time long, container bottom is prone to that ramming material encircles or paddle sizing when causing the discharging mal, because of the helical structure complexity, easy to clean paddle and install inner defective material not in the use;
4, engine installation is many: each storage container need dispose a cover spiral discharging mechanism, equipment cost height at least.If produce 30~100 of needed raw material kinds, then need a thing to dispose a machine, the result makes the equipment complexity, involves great expense.
The former feed processing enterprise that is furnished with spiral feed proportioning system (being exclusively used in micro-ingredients), existing having stopped using mostly or dismounting after using.The defective that above-mentioned spiral discharging mechanism exists is described, really is difficult to support equipment and in use accomplishes reliable and stable discharging, even cause and produce interruption.Other the drawing mechanism of commercialization (system) also have similar problem, so be not suitable for production of fodder equally.

Shown in Figure 9, be control principle block scheme of the present utility model.Its control principle is described by the following examples:
1. the interpolation of material: open the loam cake 13 of storage bin 15, drop into any an amount of granular material to storage bin 15.
2. storing material: under the situation of not discharging, because the bottom of storage bin 15 is connected with rotating disk assembly 17, the following toothed edge 28 of discharge nozzle 30 is inserted in the groove 35 above the rotating disk 37,30 plugging actions of discharge nozzle to storage bin 15, so the material in the storage bin 15 can not release warehouse, realize sealing function to material in the storehouse.
3. quantitative discharging:
The first step: connect electricity, the source of the gas of each control setup, when need with storage bin 15 in material when discharging, Operating Weight is set the interface, sets discharging weight.The collection basin 23 that is positioned at storage bin 15 belows after collection basin cylinder 25 will collect basin 23 and upwards raise, makes in the rotating shaft tube 34 that the rotating shaft 42 of driving host 41 inserts under the rotating disks 37 under the control of CPU element, realizes that two parts dock up and down.
Second step: a small amount of discharging.In the rotating shaft tube 34 below the rotating shaft 42 insertion rotating disks 37, and fastening automatically.Rotating disk 37 is by the rotating shaft 42 downward tractive of beginning and the compression springs 39 of main frame, when the following toothed edge 28 of the groove 35 of rotating disk 37 and discharge nozzle 30 is gapped, main control system 41 rotating shafts 42 begin rotation, when gap increase to can be when the material, the material in the storage bin 15 is fallen above the rotating disk 37 by feeding tube 33, and the garden arcuation blade 36 that is protruded card throws away card, when centrifugal speed is big, the inner face that material is run into scale lid 18 and scale body 19 falls on the scale pan 40 of below, after weighing, gets final product discharging.
The 3rd step: quickly discharging.If load is far fewer than the gravimetric value of setting, then the cpu instruction main frame progressively increases the discharging gap, promptly drop-down again rotating disk 37, and rotating disk 37 not stalls are moving, material in the storage bin 15 is fallen 37 of rotating disks by feeding tube 33 through discharge nozzle 30 and upward and with dish is made circular movement, under centrifugal action, the material in the storage bin 15 is constantly weighed on the scale pan 40 below being entered fast, falls in the collection basin 23.The weight scale carries out weighing to falling on the scale pan 40 at through-put weight sensor 21, and shows the numerical value of weight on telltale.
The 4th step: accurately discharging.When the weight of material on the scale pan 40 during near setting value 80~95%, 42 pairs of rotating disks of main control system 41 rotating shafts 37 are upwards pushing fast, and the gap of discharging is reduced fast, and discharging speed slows down thereupon.In rotating disk 37 rotations, when the following toothed edge 28 of discharge nozzle 30 when beginning to be inserted into rotating disk groove 35, buildup plays scavenging action in 28 pairs of grooves 35 of toothed edge, simultaneously its mainly to act on be that the restriction material can only throw away from sawtooth on a small quantity, toothed edge 28 is more little with the gap of bottom land, discharging speed is low more, and the addition that falls on the scale is few more; After the material amount reached the weight setting value in the scale pan 40, control rotating disk 37 stopped operating, and rotating disk 37 resets, and accurately the discharging process is finished.At this moment, in the scale pan: weight of material=setting weight+error amount, error amount≤± 0.005kg.The numerical value of weight of material shows on the weight read-out.
The 5th step: main frame rotating shaft 42 breaks away from disk shaft tube 34.The slot 44 of " L " type is threaded off and is resetted in main control system rotating shaft 42 counter-rotating and descending, the pivot pin 43 of rotating shaft tube 34 and main frame rotating shaft 42.
The 6th step: collection basin 23 descends and resets.Control cylinder 25 descends collection basin 23, and upper and lower two of this device partly separates, and returns to initial condition.
Above-mentioned whole discharging process is sent action command by the control unit of CPU described in Fig. 9 follow procedure, and driving host 41 is rotated, risen by instruction control rotating disk 37 or falls mobile.And the gravimetric value of material and transfer it to electric signal and feed back to cpu controller in the electronic scales Display Scale, through the CPU high-speed computation, calculate the pairing instantaneous load of rotating disk angular unit of 37 every rotations, make engine speed, lifting action coordinated operation, load moves closer to setting value, realizes that finally accurate discharging reaches the requirement of preset weight.If material in the pan of a steelyard 40>weight setting value requirement, CPU then sends the signal that reports an error, and waits for the manual correction weight error.Because the electronic scale precision is limit, if a kind of setting weight value>15kg of material, then this device is finished the quantitative discharging requirement with the weighing operation more than 2 times.
In the above-mentioned discharging process, when the discharging gap was maximum, materials should be able to freely be discharged in the storage bin 15, and discharge velocity should be able to be near the material descending speed that freely is scattered, so have the fast characteristics of discharging speed.
4. draw off material from the weight scale
The material that rotating disk 37 is quantitatively discharged from storage bin 15 drops in the pan of a steelyard 40 of weight scale, meet the setting value requirement through weighing after, scale cylinder 51 executive routines are just expansion link 52 elongations automatically, pan of a steelyard 40 is broken away from and the generation slit with scale body 19 to descending, and the material on the pan of a steelyard 40 is discharged in the collection basin 23 by this slit; Scale cylinder expansion link 52 shrinks pan of a steelyard 40 risings is resetted; This action 3 times is repeatedly gone into material vibration emptying in the pan of a steelyard in collection basin 23.
If micro-material is taken a sample, can between scale body 19 and scale lid 18, add the sampling dish (not shown) of a ring concavity in addition, under the state of Fig. 5, control rotating disk 37 rotates, and the material of being weighed is directly fallen in the sampling dish, the convenient taking-up.
5. from collection basin discharge: open valve 46 material in the jar is discharged.So far, a kind of " quantitative discharging " of material automatic weighing process is all finished.Certainly, also can finish the quantitative collection of various materials after, discharge whole materials from collection basin 23 again.
Material generation arch camber in this device solves storage bin, fracture mode
The resistance of 33 pairs of materials of storage bin 15 feeding tubes is little, and the material of 0~3kg can drain into discharge nozzle 30 at least smoothly in the tube.As the material in the feeding tube 33 partly discharge or emptying after, materials fall automatically into the feeding tube or by oblong feed supplement hole 32 feed supplement in feeding tube 33 voluntarily in the storage bin 15; Can not freely finish as feed supplement, the raw material arch camber promptly takes place in material fluidity difference or the storehouse, when discharging was interrupted, the electronic control system CPU element then rotating shaft 42 of automatic command main frame 41 was separated with 34 dropouts of rotating disk beam barrel and decline.Instruct storage bin oscillating cylinder 7 to do to stretch, contract action then, make whole storage bin 15 do teeter 3 times of nearly 90 ° of amplitudes, as shown in Figure 8, material is shaken loose or abolish and expect to encircle around its supporting-point 9 by its expansion link 8, can feed supplement in feeding tube 33.Then, the control system CPU element continues operation and is interrupted the discharging program, until satisfying the quantitative discharging requirement.
To the flowing power extreme difference, the special material of slope angle of repose 〉=70 ° can be removed feeding tube 33 and three blocks of side plates 31 in storage bin 15, and increases the mechanical agitation type arch breaking apparatus, the position that makes material in the storehouse be discharged to discharge nozzle 30 falls on the rotating disk 37, reaches the purpose of smooth discharging.
Drying mode to material in the storage bin
To dropping into storage bin 15 raw materials when if moisture content is too much, can feed dry air by the induction opening above the storage bin 15 11, discharge moisture from deflation hole 12, and setting program, regularly doing to stretch pulling by cpu instruction cylinder 7 does, storage bin 15 interior maintenances are clocklike teetered, prevent raw material caking, conglomeration.In the warehouse material repeat to shake loose and the dry air effect under, gradually reduce moisture content of raw material, realize functions/drying to material in the storehouse, increase its flowing power.The structure of storage bin 15 should be applicable to the discharging of the different raw material of various rerum naturas, and different capacity can be stored the material of different magnitudes.
