Abstract
The utility model relates to a horizontal high speed precise grader which comprises a housing and a main shaft. One end of the main shaft passes through the housing and is supported by the housing. The other end of the main shaft passes through a belt pulley and is driven to rotate by a variable frequency motor. The housing is provided with a turbine grading cage which is composed of combined blades. The turbine grading cage is fixed on the main shaft. One side of the housing is provided with an inlet communicated with the turbine grading cage, and the other side is provided with a gas collection box communicated with the turbine grading cage and provided with an outlet. The turbine grading stage in the housing is fixedly provided with a sealing impeller at a part next to the outlet end. The main shaft adopts the horizontal two-end two-point supporting and has the following advantages: greatly improved force bearing condition of the main shaft, increased operation stability of the main shaft, increased rotation speed of the main shaft, increased grading capacity of the main shaft, and capacity for separating superfine powder. The horizontal high speed precise grader is provided with a sealing impeller which rotates synchronously with the main shaft with a high speed. An air sealing mode is adopted for forming a turbine area with outward centrifugation. The powder which is not graded is prevented from entering the gas collection box and mixing with the graded powder for guaranteeing the grading precision.
Description
Technical field
The utility model relates to the preparation and the manufacture field of powder, relates in particular to a kind of horizontal high-speed fine grading machine.
Background technology
Material industry is the important component part of national economy.The powder body material engineering is the guide of development foundation of national economy industry, extensive industry and material industry that powder industry relates to are closely related, and all kinds of powder body materials are widely used in numerous industries such as chemical industry, metallurgy, machinery, microelectronics, rubber, plastics, composite, papermaking, coating printing, pharmacy, food, pigment, the energy, building materials, high technology ceramics, cosmetics, military project, environmental protection.
The fine graded technology of powder is one of most important deep process technology of nonmetallic mineral.Utilize air in progressive operation, to occupy critical role as the dynamic classification equipment of decentralized medium.The turbine air grader is because of its working stability, and classification efficiency and precision height, production capacity have obtained swift and violent development greatly, and occupied leading position gradually.But turbine air grader mainstream model is vertical at present, and main shaft generally adopts cantilevered fashion to arrange that this mode has conspicuous defective; The typical turbine air classifier there is no special seal approach usually in addition, but suppresses the top ends that particle rises to grading wheel by the high speed rotation of grading wheel, also is that effectiveness of classification is poor so can not strictly control the bulky grain leakage of grading wheel.
The utility model content
The technical problems to be solved in the utility model is: not steady in order to overcome existing turbine air grader spindle operation, problem such as classification efficiency is low, and effectiveness of classification is low provides a kind of horizontal high-speed fine grading machine.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of horizontal high-speed fine grading machine, have casing and main shaft, main shaft one end passes casing and is supported by casing, the main shaft other end drives its rotation by belt pulley by variable-frequency motor, be provided with the turbine classification cage that constitutes by combined blade in the casing, turbine classification cage is fixed on the main shaft, casing one side is provided with the import that is communicated with turbine classification cage, opposite side is provided with the plenum chamber that is communicated with turbine classification cage, plenum chamber is provided with outlet, and turbine classification cage is fixed with the sealing impeller near the port of export in the casing.
The beneficial effects of the utility model are: main shaft adopts 2 supports in horizontal two ends, has improved the stress condition of main shaft greatly, has increased the stationarity of main shaft work, is easy to significantly improve the speed of mainshaft, and then improves classifying capability, can separate super-fine powder; Be provided with the sealing impeller that rotates with the main shaft synchronous high-speed, adopt hermetic, form a centrifugal outside turbine district, stop the not classified plenum chamber that promptly enters of powder to sneak into classified powder and influence effectiveness of classification.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
Wherein: 1. casing, 2. main shaft, 3. belt pulley, 4. variable-frequency motor, 5. turbine classification cage, 6. import, 7. plenum chamber, 8. outlet, 9. sealing impeller.
The specific embodiment
As shown in Figure 1, 2, a kind of horizontal high-speed fine grading machine, have casing 1 and main shaft 2, main shaft 2 one ends pass casing 1 and are supported by casing 1, main shaft 2 other ends drive its rotation by belt pulley 3 by variable-frequency motor 4, be provided with the turbine classification cage 5 that constitutes by combined blade in the casing 1, turbine classification cage 5 is fixed on the main shaft 2, casing 1 one sides are provided with the import 6 that is communicated with turbine classification cage 5, opposite side is provided with the plenum chamber 7 that is communicated with turbine classification cage 5, plenum chamber 7 is provided with outlet 8, and turbine classification cage 5 is fixed with sealing impeller 9 near outlet 8 ends in the casing 1.
The operation principle of the utility model horizontal high-speed fine grading machine is: variable-frequency motor 4 drives main shaft 2 rotation at a high speed, main shaft 2 drives turbine classification cage 5 rotation at a high speed, when powder air mixed flow enters import 6 by side direction, when passing through the turbine classification cage 5 that constitutes by combined blade, because granular size differs and rotated and classification by turbine; Particle mainly is subjected to two kinds of strength stream viscosity resistances and centrifugal action in turbine classification cage 5, when the suffered viscous drag of particle during greater than centrifugal force, just enter the turbine center by the impeller clearance, and then enters plenum chamber 7 and discharged and sorted out by outlet 8; Viscous drag is during less than centrifugal force, and particle is because around action of centrifugal force thrown to, and returns flour mill after the lower casing 1 inwall sedimentation to pulverize again.
