Description
Technical field
The utility model belongs to agricultural mechanical field, is specifically related to a kind of corn, broomcorn straw skin marrow separator of being suitable for.
Background technology
In recent years, the problem of comprehensively, efficiently utilizing of maize straw seems particularly outstanding.Maize straw accounts for 27.39% of China's agricultural crop straw, account for China's agricultural crop straw and can collect 46% of resource, but comprehensive utilization ratio is lower.Particularly maize straw stalk for wood and papermaking aspect research also just begin.The leaf and the marrow of maize straw contain rich nutrient contents, be suitable for fertilizerization or feed utilization, and maize straw skin contain abundant cellulose, hemicellulose and lignin, is suitable for energy or stalk for the lignify utilization.Have only maize straw leaf, skin and marrow are separated, could classified use, reach the purpose of efficient utilization.
At present, that is that all right is ripe for method that the maize straw skin marrow separates and technology, has hindered each component of maize straw and has efficiently utilized.The stalk skin marrow seperator of people such as field Ziyu, Wang Chengshan invention (number of patent application: 88205735.9, patent name: stalk skin marrow seperator) realize that by mechanisms such as pulverizing, screenings the maize straw skin marrow separates.The subject matter that exists is: by screening, must have the little skin of some granularities in the marrow, also must have the bigger marrow of some granularities in the skin.Therefore, skin marrow separation rate is lower.Wang Defu; Zhao again the maize straw skin flesh seperator of continuous heavy rain invention (number of patent application: 200920244315.5, patent name: maize straw skin flesh seperator) maize straw is vertically split half, will split stalk marrow after half with cutter and scrape from the stalk skin and peel.This is invented, and method is feasible in theory, but because some particularity on the maize straw physiological structure, attenuate as the physiological bending at place, fringe position, the above stalk of physiological bending and fringe position that lodging produces, cause maize straw normally to dissect and split the stripping of scraping that half-sum is carried out marrow.In addition, stalk at results, bundling, some the non-physiological bendings and the bending of transporting, producing when depositing all will cause stalk can not normally split the stripping of scraping that half-sum is carried out marrow.This must cause this separator separation rate very low.This installs single stalk and splits and partly scrape stripping, and separative efficiency is also lower.
Therefore, existing maize straw skin marrow isolation technics and equipment imperfection also.Classification efficiently utilizes significant to maize straw to study a kind of maize straw skin marrow separation method of efficient, high separation rate and device.
Summary of the invention
At above-mentioned problems of the prior art and defective, the purpose of this utility model is to provide a kind of maize straw skin marrow separator, and this device can effectively separate stalk skin marrow, and is suitable for extensive batch process.
The technical scheme that realizes the foregoing invention purpose is a kind of maize straw skin marrow separator, comprise pulverizer, the vibration at high speed sorting unit, gas-flow separation unit, wind stopping device, centrifugal blower and motor, it is characterized in that, the discharging opening of described pulverizer is connected with the upper left charging aperture of vibration at high speed separator by connecting pipe I, the light material outlet of vibration at high speed separator top is connected with the charging aperture of gas-flow separation unit by connecting pipe II, the right side of vibration at high speed separator is provided with the heavy burder outlet, the gas-flow separation unit bottom is equipped with wind stopping device, the bottom of wind stopping device is provided with the light material outlet after the separation, outlet is connected with the end of connecting pipe III the air-flow at gas-flow separation unit top with micronic dust, and the other end of connecting pipe III is connected with fans entrance.
Described pulverizer is lappet formula pulverizer or hock type pulverizer.
Described vibration at high speed separator is high-speed oscillating sieve or vibrated fluidized bed.
Described gas-flow separation unit is cyclone separator or positive displacement discharger.
Said apparatus is mainly used in separating of stalk skins such as the corn behind the defoliation and marrow, also can directly the full stalk of stalks such as corn be separated into two parts: first stalk skin; It two is mixtures of stalk leaf and marrow.
Because the structural constituents such as skin, leaf and marrow of stalks such as corn are different, will will help efficient utilization after the each several part separation.
The utility model maize straw skin marrow separation method and device thereof have the following advantages compared with prior art:
1. separation rate height.Stalk catches a packet when pulverizing, shearing and kneading action, and stalk skin and marrow can fully be peeled off, and the material after peeling off is subjected to vibrating the effect with air-flow on the vibration at high speed separator, can fully separate.
2. productivity ratio height.Described method and apparatus can carry out skin marrow in enormous quantities to the maize straw of drying to be separated, the stalk bending, fracture, flattening, stalk directly change, feedstock direction etc. does not influence separating effect.
3. separator is simple in structure, and stalk skin marrow separation costs is low.
Description of drawings
Embodiment of the present utility model is described below with reference to accompanying drawings.
Fig. 1 is the structural representation of the utility model maize straw skin marrow separator.
The specific embodiment
Fig. 1 has provided first kind of embodiment of the utility model maize straw skin marrow separator, comprise lappet formula pulverizer 1, high-speed oscillating sieve 4, cyclone separator 6, wind stopping device 8, centrifugal blower 15, the discharging opening 2 of described lappet formula pulverizer 1 is connected with high-speed oscillating sieve 4 upper left charging apertures 19 by connecting pipe I 3, the light material outlet 13 of high-speed oscillating sieve 4 tops is connected with the charging aperture 14 of cyclone separator 6 by connecting pipe II 5, the lower right side of high-speed oscillating sieve 4 is provided with heavy burder outlet 11, cyclone separator 6 bottoms are equipped with wind stopping device 8, the bottom of wind stopping device 8 is the light material outlets 10 after separating, the air-flow at cyclone separator 6 tops and micronic dust outlet 20 is connected with the end of connecting pipe III7, and the other end of connecting pipe III7 is equipped with centrifugal blower 15.
Above-mentioned lappet formula pulverizer 1, high-speed oscillating sieve 4 and centrifugal blower 15 all have motor.Motor on the high-speed oscillating sieve is the polarization motor.
The discharging opening 2 of described lappet formula pulverizer 1 is connected with the end of connecting pipe I 3 by joint 12.
The other end of described connecting pipe III7 is connected with the inlet 16 of centrifugal blower 15.
Described centrifugal blower 15 bottoms are provided with outlet 17.
