[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] A high-consistency pulper rotor includes a pulp tank 1. An operation key 2 is provided on the upper part of the outer surface of the pulp tank 1. An annular reinforcing frame 3 is inserted and fixedly connected to the lower part of the outer surface of the pulp tank 1. Four L-shaped support plates 4 are fixedly connected in an annular array at the lower end of the annular reinforcing frame 3. The ends of the four L-shaped support plates 4 that are close to each other are pressed against the lower end of the pulp tank 1. Four support legs 5 are fixedly connected in an annular array in the middle part of the outer surface of the annular reinforcing frame 3. A reinforcing connecting block 6 is fixedly connected to the upper part of the ends of the four support legs 5 that are close to each other. The ends of the four reinforcing connecting blocks 6 that are away from the four support legs 5 are respectively fixedly connected to one end of the four L-shaped support plates 4. A rotor quick-disassembly and assembly device 8 is fixedly connected to the middle part of the lower end of the pulp tank 1. The upper part of the rotor quick-disassembly and assembly device 8 is located inside the pulp tank 1. A lower pulp pipe 7 is fixedly connected to the lower left part of the pulp tank 1.

[0031] In this embodiment, the rotor quick-release device 8 includes a motor 81. The output end of the motor 81 passes through the lower middle of the pulp tank 1 and is fixedly connected to a base mounting frame 82. A circular insertion cavity 83 is opened in the upper middle of the base mounting frame 82. Positioning cross slots 84 are opened on the upper left and upper right sides of the base mounting frame 82. Reinforcing bolts 85 are threaded and movably connected to the lower left and lower right sides of the outer surface of the base mounting frame 82. A quick-connect rotor installation structure 86 is provided directly above the base mounting frame 82. The quick-connect rotor installation structure 86 includes a fixing plate 861. A circular insertion block 863 is fixedly connected to the lower middle of the fixing plate 861. The upper and lower right sides of the fixed disk 861 are both fixedly connected with cross-shaped positioning blocks 864. The left and right sides of the outer surface of the fixed disk 861 are both fixedly connected with locking blocks 865. The lower parts of the two locking blocks 865 that are far apart from each other are provided with through screw holes 866. The upper middle part of the fixed disk 861 is fixedly connected with a rotor crushing blade assembly 862. The size of the circular insert 863 matches the size of the circular insert cavity 83. The two cross-shaped positioning blocks 864 match the size of the two positioning cross-shaped slots 84 respectively. The two screw holes 866 match the size of the two reinforcing bolts 85 respectively. The fixed disk 861 is detachably connected to the base mounting frame 82 through the two locking blocks 865 and the two reinforcing bolts 85.

[0032] The above solution involves a motor 81 driving a base mounting frame 82. A circular insert 863 is inserted into a circular cavity 83, and a cross-shaped positioning block 864 is embedded in a positioning cross slot 84 to achieve precise alignment. A reinforcing bolt 85 is then used to fix the frame by passing through the screw hole 866 of the locking block 865. Therefore, multiple tools are not required. The insertion block slot allows for quick positioning, and the bolts are used for reinforcement to complete the assembly and disassembly. This solves the traditional cumbersome problem, significantly shortens maintenance time, improves efficiency, and ensures a stable connection, thus guaranteeing the safe operation of the equipment.

[0033] In this embodiment, the rotor crushing blade assembly 862 includes a rotating reinforcing rod 8621, which is fixedly connected to the upper end of the fixed disk 861. A base disk 8622 is fixedly connected to the lower part of the outer surface of the rotating reinforcing rod 8621. Several rectangular tooth blocks 8623 are fixedly connected to the upper part of the outer surface of the base disk 8622. Five connecting protrusions 8624 are fixedly connected to the upper end of the base disk 8622. Seven sawtooth crushing blades 8625 are fixedly connected to the ends of the five connecting protrusions 8624 that are far apart from each other. The seven sawtooth crushing blades 8625 are evenly distributed. A conical spiral crushing blade 8626 is fixedly connected to the upper end of the rotating reinforcing rod 8621. The included angle between the several rectangular tooth blocks 8623 and the rotating reinforcing rod 8621 is 45 degrees. The five connecting protrusions 8624 are arranged in a ring array.

[0034] The above scheme involves rotating the reinforcing rod 8621 to drive the base plate 8622 to rotate, the rectangular toothed blocks 8623 with a 45-degree angle to initially break the slurry, the sawtooth crushing blades 8625 on the connecting protrusions 8624 of the annular array to further cut, and the top conical spiral crushing blades 8626 to deeply crush the slurry. This multi-stage crushing structure solves a single problem, fully crushes high-concentration slurry, improves the quality of the crushed slurry, and enhances the fluidity of the 45-degree toothed blocks and the annular distribution design, reducing energy consumption and improving processing efficiency.

[0035] It should be noted that this utility model is a high-consistency pulper rotor. During use, firstly, the annular reinforcing frame 3, L-shaped support plate 4, support leg 5, and reinforcing connecting block 6 stabilize the pulp tank 1. The operation key 2 controls the equipment to start, causing the motor 81 to drive the base mounting frame 82 to rotate. Through the cooperation of the circular insert block 863 and the circular insert cavity 83, and the cross positioning block 864 and the positioning cross slot 84, the quick-connect mounting rotor structure 86 is driven to rotate. The rotating reinforcing rod 8621 drives the base plate 8622. The rectangular toothed blocks 8623 with a 45-degree included angle initially crush the pulp. The sawtooth crushing blades 8625 on the annular array connecting protrusions 8624 further cut, and the conical spiral crushing blades 8626 deeply crush. Thus, the crushed pulp can be discharged through the lower pulp pipe 7. Therefore, through the cooperation of various components, high-consistency pulp is efficiently crushed. Moreover, the rotor is easy to disassemble and assemble, the equipment operates stably, greatly improving the pulping quality and maintenance efficiency, and reducing energy consumption.
