Compared with the prior art, the utility model has the advantages that: firstly, the widths of the vanes used as the main support are effectively increased so that the strength of the impeller is greatly improved to ensure stable work and reduction of energy source consumption; secondly, gaps among the vanes are made to be small and fine so that a high-precision grid is available, and the classification precision is greatly improved; and thirdly, the conical port ensures that powder can run without block so that the efficiency is remarkably improved.
Description
Technical field
The utility model relates to screening installation, and specifically, the utility model is core component-high accuracy classifying turbine that a kind of powder dry material carries out pneumatic separating.
Background technology
In powder processing, often need carry out fragmentation, grinding, the thinner material that has ground be carried out sorting, make its day mark of drafting that reaches product material, and the most common with screen cloth separation classification and mechanical selection by winnowing classification.
Screen cloth separates; As the term suggests promptly the screen cloth that weaves with the longitude and latitude twine is to the vary in size separation of particle of thin material, its separable particle diameter is according to the processing possibility decision of institute's wire gauze sieve mesh, generally can only be separated to about 400 orders, can not satisfy the requirement of super-fine processing wide-ultra fine powder body classification far away.Therefore adopt wind-force to carry out sorting in the super-fine processing scope usually, promptly the blade-carrying impeller with rotation forms grid under the condition of negative pressure, and it acts on as screen cloth; The size of diameter of particle can be told atomic little particle by the speed of the gap of blade and the rotation grid that forms that interacts.The gap of blade high more effect, the precision of then separating of speed more little, rotation is good more, and the diameter of impeller is big more, the long more treating capacity of then separating of the length of blade is big more.Be not difficult to find out; The setting angle of the gap between the length of blade, width, the blade, the geometry of classifying turbine, blade has the relation of decision to the precision of classification, the ability for the treatment of capacity.
Present existing impeller, the narrower blade of general employing, with the angled installation of wheel diameter of a circle, this is because under the principle of weight reduction instructed, angled blade can make grid narrow down.But the precision of its classification is subjected to very big influence, and this structure so need to improve wheel speed usually, is therefore brought bigger restriction because impeller is not allowed to be easy to do greatly.With calcium carbonate is example; General precision can be accomplished the 800-1250 order, hour disposal ability 300-500kg.
The utility model adopts wide blade, narrow gap, right angle orthogonal design, whole impeller can be made processing in active strength and dynamic balancing allowed band, easy for installation, working stability, hangover are extremely short, thereby reach good effectiveness of classification and desirable treating capacity ability.With calcium carbonate is example: can accomplish the 1250-6250 order, the about 300-2500kg of hour disposal ability.Improved the inherent quality of production efficiency and product greatly.
The utility model content
The purpose of this utility model provides a kind of high accuracy classifying turbine, and this lapping device has effectiveness of classification height, working stability, energy consumption is low, treating capacity is big advantage.
In powder processing, often need carry out fragmentation, grinding, the thinner material that has ground be carried out sorting, make it reach day mark of drafting of product material.How more subtly, these materials of greater amount ground sorting, be people's pursuit always, this also is the original intention of the present invention and the purpose that will reach.
In order to realize above-mentioned utility model purpose, the utility model by the following technical solutions:
A kind of high accuracy classifying turbine, by last frame plate, blade, medium frame plate, down frame plate, mandrel, and bell form; Mandrel vertically is connected up and down with bell; Last frame plate, medium frame plate, down frame plate be parallel to each other and with mandrel, bell is orthogonal thereto is connected; Blade is vertically lapped in last frame plate, medium frame plate, following frame plate, and then forms a complete set of high accuracy classifying turbine.
Described blade is a multi-disc.The principle of pneumatic separating is: make material pass through certain clearance, so that separated, these gaps are to be formed mutually by each blade, thereby blade must be a multi-disc.
Described width of blade is 50mm-150mm.This is the important feature that the utility model is different from traditional classifying turbine, adopt the benefit of wide blade to be: whole impeller can be made processing in active strength and dynamic balancing allowed band, easy for installation, working stability, hangover are extremely short, thereby reach good effectiveness of classification and desirable treating capacity ability.Thereby width of blade is 50mm-150mm.
Gap between the described blade is 0.5mm-15mm.Gap length between the blade has determined to sub-elect the fineness of material, and the gap is that 0.5mm-15mm just can cover the particle size range that ultra-fine material need reach substantially.
The taper angle of described bell is 0 °-45 °.According to experience in the past, we find that impeller is when long-term the use, if the bottom is not provided with the bell of band taper angle, have dust and be accumulated in the impeller bottom, cause impeller disequilibrium gradually, with damage equipment, thereby we have designed a bell in this utility model when serious, these bell number of degrees are 0 °-45 °, so just can effectively solve the problem that the inner powder of impeller is piled up.
The utlity model has following advantage:
Owing to adopted technique scheme, the present invention compared with existing device, technical matters have following advantage and effect:
A, owing to effectively increase width as the blade of main support, the intensity of impeller itself is increased greatly, so that working stability, energy resource consumption minimizing.
B, since blade between the gap do little, do essence, so can accomplish high-precision grid, effectiveness of classification is improved greatly.
C, bell have guaranteed powder expedite operation under negative pressure, and efficient obviously improves.

The specific embodiment
Embodiment 1
As shown in Figure 1, 2, a kind of high accuracy classifying turbine is made up of last frame plate 1, blade 2, medium frame plate 3, following frame plate 4, mandrel 5, bell 6; Mandrel 5 vertically is connected up and down with bell 6; Last frame plate 1, medium frame plate 3, down frame plate 4 be parallel to each other and with mandrel 5,6 orthogonal thereto connections of bell; Blade 2 is vertically lapped in last frame plate 1, medium frame plate 3, following frame plate 4, and then forms a complete set of high accuracy classifying turbine.
During running, material after the grinding is inhaled to impeller by negative pressure, meets the powder of setting the sorting fineness and is inhaled into impeller inside by the gap between the blade 2, and then be collected, then returned greater than the powder of setting the sorting fineness, enter lapping device once more and ground by blade 2.
100 blades, width of blade 100mm, impeller clearance 5mm, 45 ° of bell taper angles, the calcium carbonate after sorting is ground is set sorting fineness 1250 orders, and a throughput per hour is 1000kg.
