Description

A kind of cyclone is broken up water conservancy diversion grader under wide-mouth
Technical field
The utility model relates to a kind of submicron order and micron order (particle size diameter 500-5000nm) superfine powder precision classifying equipoment, belongs to superfine powder gas phase classification field.
Background technology
In existing powder institute phase classifying equipoment, conventional have a centrifugal cyclone classifier, conventional cyclone classifier generally comprises cyclone body, the aggregate bin of cyclone body below, cyclone body sidewall arranges air inlet pipe, the air inlet of air inlet pipe and cyclone body are tangential direction air inlet, and cyclone body top arranges the Xiang Liuguan connecting with air inducing equipment.
Above-mentioned this structure, air-flow tangentially enters after cyclone body at cyclone classifier air inlet, in cyclone classifier, form whirlwind and turn gas, powder enters after cyclone body under the effect of air-flow, in cyclone body, form the outside circulation moving downward near cyclone body madial wall position because of the effect of gravity and centrifugal force, in air-flow, bulky grain body moves downward and enters aggregate bin along whirlwind body wall, in cyclone body, be formed centrally the interior circulation moving upward, in air-flow, tiny powder moves upward at cyclone body center, thereby powder is carried out to cyclone centrifugal classification.
In in said structure, circulation is reverse and go at uphill process China and foreign countries sidewind and the outside circulation air-flow moving downward, because there is eddy current and short circuit phenomenon in conventional cyclone classifier inlet air flow and Xiang Liuguan outlet, part enters a stream blast pipe without the powder particle disperseing in the lump with short circuit air flow, enter in fines collection equipment, with separate after fine powder mix form pollute. in addition, the conventional one or more air inlet pipe of cyclone classifier equipment, but air inlet power comes from the air inducing equipment of fines collection device rear end, air inlet and whirlwind clarifier inside and outside differential pressure that general air inducing device level provides are less than 50Kpa, flow rotation power is less, powder enters after cyclone body under the effect of air-flow, the resistance that air-flow is subject to is large, thereby cause flow rotation speed slower, the centrifugal force that powder particle is subject to is less, powder dispersity is poor, the particle aggregation fully not disperseing forms larger cluster of grains together, because particle weight is more greatly along with outside circulation enters in meal collecting device, cause classification efficiency to reduce, effectiveness of classification is poor, superfine powder classification difficulty. separately, because powder is ultra-fine, the mobility of powder is poorer, through break up with classification after powder easily again reunite and form in classifying equipoment and adhere to and pile up, thereby cause classifying equipoment to stop up the lasting stability that has affected classifying equipoment running.
Utility model content
The utility model, for present technical above-mentioned deficiency, provides one not to be prone to eddy current and short circuit phenomenon, simple in structure, and dispersion effect is good, and classification efficiency and precision are high, is difficult for stopping up the gas phase classifying equipoment of convenient operation.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of cyclone is broken up water conservancy diversion grader under wide-mouth, comprise cyclone body, cyclone body indoor design is flat rotary fluid structure, be arranged at the multiple tangential high pressure admission mouth of cyclone body surrounding, setting is positioned at the charging aperture in cyclone body outside, be arranged at the lower flow-guiding structure in cyclone body, be arranged at interior circulation gas outlet upwards, flow-guiding structure center, be arranged at the whirlwind cone bucket of cyclone body lower end and the meal recovering hopper of below thereof, interior circulation outlet connects with fine powder collector, and interior recycle stream is discharged or discharged via air-introduced machine after fine powder collector.
As improvement, described high pressure admission mouth quantity is 2-36, is evenly tangential distribution structure of week, can ensure that air inlet is evenly distributed, and reduces resistance, increases the rotary speed of air-flow, thus the larger centrifugal force of generation.
As improvement, air inlet is designed to amplify mouth structure, as Venturi tube structure, can effectively ensure to enter after cyclone body through high pressure admission mouth air-flow stable.
As improvement, flow-guiding structure lower end diameter is doubly size of interior circulation gas outlet internal diameter 1-2, and outer cone wall range of taper is 30-90 degree (being the angle between side money or bus and the horizontal direction of cone), to prevent in cyclone body causing fine powder to pollute without fully dispersing with the powder of classification because cyclone vortex and short circuit enter gas outlet.
As improvement, under cyclone body flow-guiding structure, can be designed to back taper, to strengthen internal circulation shaping effect.
As improvement, whirlwind cone bucket outer cone wall range of taper is 30-90 degree (being the angle between side money or bus and the horizontal direction of cone).
As improvement, whirlwind cone bucket internal diameter suitable for reading is not less than the internal diameter of cyclone body, and be not less than 3 times of baffle lower end diameter, to guarantee that the powder that enters cyclone body just can enter in whirlwind cone bucket after sufficient airflow crash disperses, and separate to the space of inside and outside circulation abundance.
As improvement, upper end, interior circulation gas outlet is not higher than cyclone body center.
The utility model beneficial effect:
The utility model cyclone body is flat high pressure cyclone structure, and multiple tangential high pressure admission High Rotation Speeds produce larger shearing-crushing power, can effectively carry out abundant gas breaking to powder and break up; The high speed cyclone that high pressure admission forms produces larger centrifugal force, can carry out large or fine granule separation to powder efficiently, meal enters in meal collector along with outside circulation moves downward under the effect of centrifugal force and gravity, and fine powder is along with interior circulation enters in fine powder collector through interior circulation gas outlet; Flat cyclone structure, sufficient rotary speed is provided, be arranged at the flow-guiding structure in cyclone body, fully specification the running route of rotational flow gas and the powder that together rotates along with gas, thereby eddy current and air flow shortcircuit phenomenon in cyclone body and cone bucket are solved, there will not be meal to mix thereby ensured to enter in the fine powder of interior circulation gas outlet, ensure classification high efficiency and stability; Downward interior circulation gas outlet, is convenient to interior recycle stream and fine powder and enters rapidly the saliva of giving vent to anger; The whirlwind cone bucket wide-mouth structure that is designed to suitable for reading, ensure that the powder after whirlwind is broken up can carry out carrying out classification process in whirlwind cone bucket along with air-flow continues operation immediately, reduce the time of staying of powder, reduce and excessively break up the deformation that powder granule is caused, accelerate hierarchical speed, increased classifying capability.
