[0001] This utility model relates to the field of feed processing, and in particular to the field of rotary screen technology, specifically a rotor assembly of a rotary screen. Background Technology

[0002] Rotary screens are widely used in feed, food, chemical, and pharmaceutical industries.

[0003] The rotary screen is mainly composed of a screen, a shell, and a rotary rotor assembly. The material enters the screening chamber, is broken up by the scraper on the rotor, and then passes through the brush to screen out impurities and grade materials in the feed raw materials, so that the material passes through the screen of the required size.

[0004] The current mainstream rotor screen method is insufficient to meet the needs of feed mills. Often, during the production process, material blockage of screen holes, uneven screening, and slow discharge speed will occur, thus affecting production efficiency. Summary of the Invention

[0038] This invention proposes a rotor assembly for a rotary screen, which enhances the cleaning ability and material separation speed of the rotary screen and reduces the load on the powder grinding system.

[0039] In general, the rotor assembly of the rotary screen proposed in this utility model mainly includes: a shaft 1, a fixing and tightening module 2, a brush plate assembly 3, and a scraper assembly 4. (See also...) Figure 1 It shows the arrangement of shaft 1, fixed tightening module 2, brush assembly 3 and scraper assembly 4.

[0040] The rotor assembly of the rotary screen proposed in this utility model optimizes the corresponding structural performance based on the original rotary screen. A fixing and tightening module 2 is added to the shaft to achieve a tight-fitting effect on the brush plate assembly 3 and the scraper assembly 4. The brush plate assembly 3 and the scraper assembly 4 are arranged at intervals, and the number of brush plate assembly 3 and scraper assembly 4 is increased. This increases the cleaning ability and separation speed of the scraper 41 and brush 31 in conveying raw materials and cleaning the screen. The scraper 41 and brush 31 adopt a relatively simple installation and fixing structure to facilitate quick replacement of the scraper 41 and brush 31. Furthermore, the scraper 41 and brush 31 are set at an angle to increase the separation area for raw materials.

[0041] The aforementioned fixing and tightening module 2 is provided in three sets. These three sets of fixing and tightening modules 2 are equally spaced and fitted onto the outside of the shaft 1. The fixing and tightening module 2 includes: a first-layer rotor plate 21, a second-layer left rotor plate and a second-layer right rotor plate 23, and a screen fixing plate 24. The first-layer rotor plate 21 is equally spaced and fitted onto the outside of the shaft 1. A shaft hole 22 is formed in the center of the first-layer rotor plate 21, and the shaft hole 22 is interference-fitted with the shaft 1. The second-layer left rotor plate and the second-layer right rotor plate 23 are assembled into a disc shape and are bolted together and mounted on one side of the first-layer rotor plate 21. The screen fixing plate 24 has a dividing groove in the center, and the screen fixing plate 24 is divided into two sections by bolts. The bolts are respectively connected to the side of the second-layer left rotor plate and the second-layer right rotor plate 23 away from the first-layer rotor plate 21. The outer walls of the screening plate 24 are provided with L-shaped protrusions 25 at equal intervals. There are 6 L-shaped protrusions 25. The screening component mounting plate 5 is connected to one side of the L-shaped protrusion 25 by bolts. The second-layer left rotor plate and the second-layer right rotor plate 23 are respectively connected to the segmented screening plate 24. The screening component mounting plate 5 is connected to one side of the L-shaped protrusion 25 by bolts. Because the angle of the screening plate 24 relative to the first-layer rotor plate 21 can be changed by rotating the second-layer left rotor plate and the second-layer right rotor plate 23, the tilt angle of the scraper 41 and the brush 31 can be changed.

[0042] It should also be noted that the second-layer left rotor plate, the second-layer right rotor plate and the screen fixing plate 24 are provided with a clearance hole 26 in the center. The diameter of the clearance hole 26 is larger than the diameter of the shaft hole 22. The first-layer rotor plate 21 is interference-fitted with the shaft 1 through the central shaft hole 22, so the first-layer rotor plate 21 will not move. The second-layer left rotor plate and the second-layer right rotor plate are rotated to change the bolt installation position and adjust the installation angle.

[0043] The brush assembly 3 and scraper assembly 4 are arranged at intervals on the outer walls of the fixed tightening module 2. The brush assembly 3 includes a brush 31 and a first connecting screw 33. Three sets of brushes 31 are provided, and the three sets of brushes 31 are evenly spaced around the screen fixing plate 24. One side of the brush 31 contacts the screen mounting plate 5. The side of the brush 31 away from the brush head has a first mounting hole 32 at equal intervals. The first connecting screw 33 passes through the first mounting hole 32, and the bottom of the first connecting screw 33 passes through the first mounting hole 32. 2. Connected to the screen mounting plate 5, the scraper assembly 4 includes: a scraper 41 and a cover plate 42. The scraper 41 is evenly spaced around the screen fixing plate 24 between adjacent brushes 31. One side of the scraper 41 contacts the screen mounting plate 5. The cover plate 42 is located on the side of the scraper 41 away from the screen mounting plate 5. The cover plate 42 has two mounting holes 43 evenly spaced on it. A second connecting screw 44 passes through the second mounting hole 43. The bottom of the second connecting screw 44 passes through the scraper 41 and connects to the screen mounting plate 5.

[0044] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
