[0021] Please see Figures 1-4 This utility model provides a grinding mill discharge rotor, including a turntable 1, a rotor body 3 fixedly installed at the end of the turntable 1, and a positioning groove 4 is opened on the outer surface of the rotor body 3. At the same time, a filter screen mounting groove 31 is opened on the surface of the rotor body 3, and a screw hole 5 is opened on the outer circumference of the rotor body 3. A filter screen cylinder 7 is installed on the outer side of the rotor body 3, and a splicing strip 10 is fixedly provided on the inner circumference of the right side of the filter screen cylinder 7. At the same time, multiple sets of filter holes 8 are evenly opened on the outer surface of the filter screen cylinder 7, and the distance between two adjacent sets of filter holes 8 is the same. A bushing 21 is fixedly installed on the front side of the turntable 1, and a main shaft mounting groove 2 is opened inside the bushing 21.

[0022] As can be seen from the above, when the grinding machine is in use, the drive motor starts and drives the turntable 1 to rotate through the main shaft. The turntable 1 drives the filter screen 7 to rotate through the rotor body 3, so as to achieve the grinding and filtering of the slurry. The rotor body 3 is cylindrical in shape and its surface structure is uniform. It will not rotate eccentrically or break the shaft. When the rotor body 3 rotates, its surface wear is uniform and there will be no severe local wear.

[0023] The axial cross-section of the turntable 1 and the bushing 21 is a concentric circle structure, and six sets of reinforcing seats 22 are evenly arranged between the bushing 21 and the turntable 1, while the distance between two adjacent sets of reinforcing seats 22 is consistent.

[0024] In a preferred embodiment, the positioning groove 4 is adapted to the size of the filter cylinder 7, and the depth of the positioning groove 4 is equal to the thickness of the filter cylinder 7. At the same time, the axial cross-sections of the rotor body 3 and the filter cylinder 7 are concentric circles.

[0025] As a preferred embodiment, four sets of equidistant locking seats 9 are fixedly provided on both sides of the circumferential surface of the filter cylinder 7, and four sets of equidistant screw holes 5 are provided on both sides of the circumferential surface of the rotor body 3.

[0026] The screw hole 5 is connected to the through hole on the locking seat 9, and the fixing bolt passes through the through hole on the locking seat 9 and is screwed and fixed inside the screw hole 5.

[0027] In a preferred embodiment, four sets of splicing grooves 6 are evenly opened on the outer wall of the right circumference of the rotor body 3, and four sets of splicing strips 10 are evenly fixed. At the same time, the dimensions of the splicing strips 10 and the splicing grooves 6 are matched, and the cross sections of the splicing strips 10 and the splicing grooves 6 are set as right-angled trapezoids.

[0028] As can be seen from the above, when using the filter cylinder 7, during positioning and installation, the filter cylinder 7 is held in hand, and the four sets of splicing strips 10 on the filter cylinder 7 are respectively inserted into the four sets of splicing slots 6 opened on the outer side of the rotor body 3. This allows the filter cylinder 7 to be positioned and installed on the outer side of the rotor body 3. At the same time, the splicing strips 10 and splicing slots 6 can quickly align the through holes on the locking seat 9 with the screw holes 5, allowing for quick installation or removal of the filter cylinder 7. This minimizes the filter cylinder 7 replacement time of the grinder and improves the efficiency of the grinder.

[0029] The four sets of splicing strips 10 are respectively inserted into the four sets of splicing grooves 6, and the filter cylinder 7 is positioned and installed on the outside of the positioning groove 4 through the splicing strips 10 and the splicing grooves 6.

[0030] Working Principle: During operation, the grinder's drive motor starts, driving the turntable 1 to rotate via the main shaft. The turntable 1, through the rotor body 3, drives the filter cylinder 7 to rotate, thus grinding and filtering the slurry. The rotor body 3 is cylindrical with a uniform surface structure, preventing eccentric rotation and shaft breakage. During rotation, the surface of the rotor body 3 experiences uniform wear, avoiding severe localized wear. Simultaneously, when positioning and installing the filter cylinder 7, the four sets of splicing strips 10 on the filter cylinder 7 are inserted into the four sets of splicing slots 6 on the outer side of the rotor body 3. This allows for positioning and installation of the filter cylinder 7 on the outside of the rotor body 3. The splicing strips 10 and splicing slots 6 also allow for quick alignment of the through holes 9 and screw holes 5 on the locking seat 9, enabling rapid installation and removal of the filter cylinder 7. This minimizes filter cylinder 7 replacement time and improves the grinder's efficiency.
