Abstract
The utility model relates to a powder concentrator, which mainly comprises a shell, a rotor belt and rotor blades. A projection arranged in the shell matches with the rotor belt and the rotor blades; a circle of first felted wool is arranged on the upper surface of the projection; the inner edge of the first felted wool contacts with the outer edge of the rotor belt; a circle of second felted wool is arranged on the lower surface of the projection; and the inner edge of the second felted wool contacts with the rotor blades. The powder concentrator is capable of effectively preventing powder with a larger grain size inside the rotor blades from entering a cavity at the upper end of the shell through the gap between a rotor and the shell, improves granularity stability of products, and is also capable of preventing powder with a smaller grain size inside the cavity at the upper end of the shell from entering the rotor blades again and leading to repeated screening, labor hour waste and operating efficiency reduction. In addition, by the aid of arrangement of the felted wool, abrasion of the rotor can be reduced, the service lives of the rotor blades are prolonged, and production cost is reduced.
Description
Technical field
The utility model relates to the powder manufacture field, especially a kind of powder concentrator.
Background technology
At present the inner powder concentrator that uses of industry all has only casing and rotor blade to form, because rotor blade needs to rotate, so must leave certain clearance between itself and the casing, causes the sealing effectiveness of powder concentrator inside poor.And this gap can directly cause the bigger powder of rotor blade internal particle can directly enter in the chamber of casing upper end, has reduced the screening effect of powder concentrator, causes the granule stability of product poor.On the other hand, when rotor blade and casing, retained a certain amount of powder in the gap between rotor banding and the casing after, can cause the wearing and tearing of rotor blade and rotor banding to quicken, significantly shorten service life.
The utility model content
The purpose of this utility model is to provide a kind of screening effect good for the deficiency that solves above-mentioned technology, the powder concentrator of long service life.
In order to achieve the above object, the powder concentrator that the utility model is designed, it mainly comprises casing, rotor banding and rotor blade, rotor banding and rotor blade are one, there is a projection to cooperate in the casing with rotor banding and rotor blade, at protruding upper surface one circle, first wool felt is set, first wool felt is fixed on protruding upper surface by pad and screw, the inner edge of first wool felt and the outside of rotor banding are in contact with one another, in convex lower surface one circle, second wool felt is set, second wool felt is fixed on convex lower surface by pad and screw, and the inner edge of second wool felt contacts with rotor blade.This structure can prevent that the powder of larger particles from entering by projection and gap between rotor in the cavity of casing upper end, improves the particle size stable of product.
The overlapping length of first wool felt and rotor banding is 3-5mm, and the overlapping length of second wool felt and rotor blade is 2-3mm.Such structure can guarantee that the sealing property between casing and the rotor is better.
The resulting powder concentrator of the utility model, it respectively is provided with one deck wool felt up and down, prevent that the powder of the larger particles of rotor blade inside from entering the cavity of casing upper end by the gap between rotor and the casing, improved the particle size stable of product, the powder than small grain size that can also prevent casing upper end inside cavity reenters rotor blade inside, cause repeating screening, waste man-hour, reduce work efficiency.Being provided with of wool felt can prevent that powder from entering the gap between rotor and the casing in addition, reduces the wearing and tearing of rotor, prolonged the service life of rotor blade, reduced production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is a partial sectional view of the present utility model.
1 casing, 2 rotor bandings, 3 rotor blades, 4 protruding upper surfaces, 5 convex lower surface, 6 first wool felts, 7 second wool felts, 8 pads, 9 screws.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As Fig. 1, shown in Figure 2, the powder concentrator that present embodiment is described, it mainly comprises casing 1, rotor banding 2 and rotor blade 3, rotor banding 2 is an one with 3 on rotor leaf, there is a projection to cooperate in the casing 1 with rotor banding 2 and rotor blade 3, at protruding upper surface 4 circle first wool felt 6 is set, first wool felt 6 is fixed on protruding upper surface 4 by pad 8 and screw 9, the outside of the inner edge of first wool felt 6 and rotor banding 2 is in contact with one another, in convex lower surface 5 circle second wool felt 7 is set, second wool felt 7 is fixed on convex lower surface 5, the second wool felts 7 by pad 8 and screw 9 inner edge contacts with rotor blade 3.First wool felt 6 and rotor banding 2 overlapping length are 3-5mm, and second wool felt 7 and rotor blade 3 overlapping length are 2-3mm.
Claims (2)
1. powder concentrator, it mainly comprises casing, rotor banding and rotor blade, rotor banding and rotor blade are one, there is a projection to cooperate in the casing with rotor banding and rotor blade, it is characterized in that one circle, first wool felt being set at described protruding upper surface, first wool felt is fixed on protruding upper surface by pad and screw, the inner edge of first wool felt and the outside of rotor banding are in contact with one another, in convex lower surface one circle, second wool felt is set, second wool felt is fixed on convex lower surface by pad and screw, and the inner edge of second wool felt contacts with rotor blade.
2. powder concentrator according to claim 1 is characterized in that the overlapping length of described first wool felt and rotor banding is 3-5mm, and the overlapping length of second wool felt and rotor blade is 2-3mm.
