Abstract
The utility model discloses a novel powder screening machine, which comprises a casing. A feed hole, an air inlet and an air outlet are arranged on the casing, an analyzer and a first guide plate are installed in the casing, the included angle Beta between the first guide plate and the feed hole is 10 to 80 degree, a second guide plate is also installed in the casing, and the symmetry between the second guide plate and the first guide plate is mirror symmetry. The novel powder screening machine has the advantage that the structure is simple, during the falling process of the powder, under the function of the guide plates, the falling speed can be decreased, thus the distribution is uniform and the sorting effect is excellent; after the space between the baffle plate and the inner wall of the casing is fully filled with the material, the space of the powder screening chamber is compressed, the ventilating resistance and the air pressure loss are reduced, thereby the air diffusing function is realized, the effective air volume for powder screening is enhanced, and the energy consumption is reduced.
Description
Technical field
The utility model relates to a kind of novel powder concentrator.
Background technology
In the closed-circuit system of miropowder from dregs of metallurgy productive technology of short flow, go into to grind the fineness and the uniformity thereof of slag and control by the V-type powder concentrator.Therefore, as the visual plant of technique for producing miropowder from dregs of metallurgy, V-type powder concentrator performance is to improving system's production efficiency, and cutting down the consumption of energy has crucial meaning.
By Bo Te of Britain forces (Mambord) and not enlightening (Moadie) invention in 1885, patent is obtained in Germany in the back to powder concentrator, is referred to as first generation powder concentrator, i.e. centrifugal classifier on development history usually the earliest.Though the classification efficiency of this powder concentrator is low, but develop the basis of the second generation, third generation powder concentrator later on.
Second generation powder concentrator is representative with the cyclone type powder sorting machine of Germany big vast fort one dimension Dagua Inc. exploitation, and grinding efficiency has had tangible improvement, and is domestic at this equipment of the many employings in the front and back seventies, uses quite general.
Different with centrifugal classifier, Victor lattice (Wedog) type cyclone type powder sorting machine has been cancelled big blade, is changed into by interior circulation and uses the outer circulation that adds blower fan and whirlwind tube, fine powder to change by analyzer and the collection of whirlwind tube, and its fines collection rate is higher.Therefore the dust content at circulating current center reduces, and selects powder process fine powder to interfere with each other and reduces, and the also corresponding raising of classification efficiency generally can reach more than 80%, can increase production 40%-60% than opening streaming system.
Though obtained certain progress, grinding efficiency is still not high enough, and it is not very good selecting the powder effect, need repeatedly repeat just can fully select fine powder, also brings the higher problem of energy consumption thus.
The utility model content
The technical problems to be solved in the utility model is that to overcome in the prior art powder concentrator grinding efficiency not high enough, and effect is not very good, and the deficiency that energy consumption is higher provides a kind of grinding efficiency height, and is satisfactory for result, the novel powder concentrator that energy consumption is low.
For realizing above purpose, the utility model is achieved through the following technical solutions:
Novel powder concentrator, comprise housing, have charging hole, air inlet and air outlet on the housing, analyzer is installed in the housing, first stock guide is installed in the described housing, the angle β of first stock guide and charging hole axis is the 10-80 degree, and second stock guide also is installed in the housing, second stock guide and the first stock guide mirror image symmetry.
Wherein, the described second stock guide number is more than two, and from second second stock guide, each second stock guide end is than outstanding 5-20 centimetre of last one second stock guide end.
Wherein, described air outlet both sides are equipped with baffle plate.
Wherein, described housing has peep hole.
The beneficial effect of novel powder concentrator of the present utility model is: simple in structure, material is subjected to the stock guide effect at dropping process, and falling speed is slowed down, and is evenly distributed good separation effect; After baffle plate and inner walls institute clip space are filled up by material, compress the space in the separating chamber, reduced flowing resistance and air loss, played the effect of diversion air, increased and effectively selected the powder air quantity, reduced energy consumption.
Description of drawings
Fig. 1 is a novel powder concentrator enclosure interior structural representation of the present utility model;
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is done a detailed description:
Referring to Fig. 1, novel powder concentrator, comprise housing 1, have charging hole 2, air inlet 5 and air outlet 6 on the housing 1, analyzer 8 is installed in the housing 1, first stock guide 3 is installed in the described housing 1, first stock guide 3 is the 10-80 degree with the angle β of charging hole 2 axis, plural second stock guide 4 also is installed in the housing 1, and from second second stock guide 4, each second stock guide, 4 end is than outstanding 5-20 centimetre of last one second stock guide end.Second stock guide 4 and first stock guide, 3 mirror image symmetries, described air outlet 6 both sides are equipped with baffle plate 7.Also have peep hole 9 on the housing 1.
During use, material is sent in the housing 1 from charging hole 2, in the dropping process, through stopping of first stock guide 3 and second stock guide 4, can delay the speed that material descends, wind blows to the material the decline in air inlet 5 enters housing 1, the suction that cooperates analyzer 8 simultaneously, suck fine powder in the analyzer and send outside the housing 1, the bulky grain material descends and to fall in the space between baffle plate 7 and housing 1 inwall, the bulky grain material is many more, and then the space in the housing 1 is more little, can more effectively make the material of wind in descending.Can watch situation in the housing 1 by peep hole 9.
Powder concentrator of the present utility model and Victor lattice (Wedog) type cyclone type powder sorting machine are compared test,
The particle diameter of the powder that use Victor lattice (Wedog) type cyclone type powder sorting machine is selected distributes as a comparison case, and the particle diameter of the powder that use the utility model powder concentrator is selected distributes as testing example, data such as table 1:
Table 1:
| Discharging | ＞0.5 | 32.75 | 32.63 | 30.69 | 32.02 | 9.83 | 8.97 | 9.25 | 9.35 |
| ＜0.5 | 67.25 | 67.37 | 69.31 | 67.98 | 90.17 | 91.03 | 90.75 | 90.65 |
As can be seen from Table 1, in the material that Victor lattice (Wedog) type cyclone type powder sorting machine is selected＜the 0.5mm granule content is about 67.93%, in the material that the utility model powder concentrator is selected＜the 0.5mm granule content is about 90.65%, improves about 22.72%;
Table 2 is the technical parameter contrast of the utility model powder concentrator and Victor lattice (Wedog) type cyclone type powder sorting machine
As can be seen from Table 2, powder concentrator air quantity in the utility model increases considerably, per hour disposal ability increases, treating capacity after the improvement is about the twice of prototype, Victor lattice (Wedog) type cyclone type powder sorting machine general power is 70kw, and electricity price is by 0.75 yuan/degree, and then former processing power consumption is 70/4.5*0.75=11.67 unit/ton, the power consumption of the utility model powder concentrator is 70/9*0.75=5.83 unit/ton, and the processing power consumption reduces about 50%.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
