All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The utility model discloses a cylindrical straight blade classifier rotor which structurally comprises a sleeve 1, blades 2 and a supporting plate, wherein the supporting plate comprises an upper plate 3, a middle plate 4 and a lower plate 5, the sleeve 1 is fixedly arranged in the middle of the middle plate 4 and the lower plate 5, the blades 2 are fixedly arranged on the outer circumference of the supporting plate, the diameters of the upper plate 3, the middle plate 4 and the lower plate 5 are the same, the diameters of the upper part and the lower part of the cylindrical straight blade rotor are the same, the linear speeds of rotation are the same, and the cutting particle sizes are the same; the structure is relatively simpler, the manufacture is easy, the service life is long, and the yield is high.
In some embodiments, the supporting plate may adopt a structure scheme that the supporting plate includes an upper plate 3, a middle plate 4 and a lower plate 5, and the middle plate 4 is fixed between the upper plate 3 and the lower plate 5. The supporting plates play a role in strengthening the fixing strength of the blades 2, and the three supporting plates are arranged, so that the strength is increased and the air volume is not influenced in the using process.
In some embodiments, the sleeve 1 may adopt a structure that two positioning portions 6 are provided on the sleeve 1 for fixing with the middle plate 4 and the lower plate 5. The positioning portions 6 are two steps arranged on the sleeve, and the positioning portions 6 are used for fixing the upper plate 3 and the middle plate 4, so that the upper plate 3 and the middle plate 4 are welded on the sleeve in parallel.
In some embodiments, the sleeve 1 may also adopt a structure scheme that a central hole 7 is arranged in the middle of the sleeve 1, and a clamping groove 8 is arranged on the central hole 7. The central hole 7 is arranged to ensure that the main shaft of the grader is arranged in the sleeve 1, and the clamping groove 8 is formed in the central hole 7, so that the main shaft of the grader can be in key connection with the sleeve 1, the sleeve 1 is driven to rotate when the main shaft of the grader rotates, the sleeve 1 drives the supporting plate to rotate, and the supporting plate drives the blades 2 to rotate, thereby realizing the function of grading materials.

In some embodiments, the fixing grooves 9 may also be configured such that the fixing grooves 9 are uniformly distributed on the circumference of the support plate and are arranged obliquely to the diameter direction of the support plate. The advantage of the uniform distribution of the fixing grooves 9 is that the blades 2 mounted thereon are uniformly distributed, and when the rotor rotates, a vortex is formed, and the vortex enters the rotor through the gaps of the blades 2, and the coarse material is collided, so that the coarse powder falls into the lower part of the flour mill for further grinding.
In the powder selecting process, product particles are subjected to different gravity, conveying force and centrifugal force in airflow to achieve the purpose of screening, fine powder in the powder-containing airflow enters the interior of a cylindrical straight blade classifier rotor through gaps among blades 2 which are uniformly arranged at intervals, the fine powder cannot enter the interior of the cylindrical straight blade classifier rotor if the fineness is too coarse, the fine powder rises with circulating air along with the fineness meeting the specification and enters a cyclone separator, the fine powder is settled to form a fine powder finished product, and the coarse powder in the powder-containing airflow cannot enter the interior of the cylindrical straight blade classifier rotor due to the fact that the speed of the coarse powder is relatively low, falls into a main machine after colliding with the blades 2 and is reground.
It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the utility model.
