Description

Technical Field

[0001] This utility model relates to the technical field of pulping equipment, specifically to a high-solids-content organic pulping rotor and pulping machine. Background Technology

[0002] High-solids organic pulping refers to the process of converting organic materials containing a high proportion of solids (such as agricultural waste, food processing residues, and municipal organic waste) into a homogeneous, highly fluid slurry. This slurry is typically used for bioenergy production (such as biogas or bioethanol), fertilizer manufacturing, or other forms of resource recovery.

[0003] Currently, the limited working method and structure of pulping machines result in a single pulping method, primarily relying on hydraulic vortexing and the impact of pulp against the machine's internal wall to achieve pulping. With the rotor fixed inside the pulping machine, the limited mixing area necessitates additional mixing time for uniform mixing, leading to low pulping efficiency. Furthermore, the quality of the pulp after pulping is low; for hard pulps, incomplete pulp decomposition is common, resulting in uneven particle size and uneven pulp quality. Therefore, improvements and development are needed to address these issues. Utility Model Content

[0004] This invention provides a high-solids-content organic pulping rotor and pulper, which features blades of varying lengths. This design allows for greater relative motion between the pulp and material within the same rotation cycle of the turntable, increasing shearing opportunities and facilitating the rapid breakdown of large pulp particles into smaller ones, thereby improving pulping efficiency. Specific implementation details are as follows:

[0005] A high-solids-content organic pulping rotor includes a main body, the main body including a turntable and blades disposed on the turntable, the blades extending outwards in a direction deviating from the axis of the turntable, the blades having shearing blades that are in the same direction of rotation as the main body, and multiple blades being disposed, the multiple blades having different lengths and extending in the same direction to increase the radial pulp area of ​​the main body.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings and examples:

[0026] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0027] Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0028] Example 1, combined with Figures 1 to 3 As shown, this embodiment provides a high-solids-content organic pulping rotor, including a main body 10. The main body 10 includes a turntable 7 and blades disposed on the turntable 7. The blades extend outwards away from the axis of the turntable 7. Each blade has a shearing edge, and the shearing edge is aligned with the rotation direction of the main body 10. Multiple blades are provided, and the lengths of the multiple blades are different, but their extension directions are consistent, thereby increasing the radial pulp area of ​​the main body 10. For example, the turntable 7 is disc-shaped, and the blades are disposed on the outer circumferential surface of the turntable 7, extending outwards away from the axis of the turntable 7 to create a vortex in the pulp, improving the pulping efficiency. The rotation of the turntable 7 drives the blades to rotate synchronously. Under the action of the liquid and the shearing action of the blades, large organic particles in the pulp are rapidly decomposed into smaller particles, thereby improving the quality of the pulp and facilitating subsequent processing.

[0029] Specifically, multiple blades of varying lengths are spaced apart along the circumference of the turntable 7. The blades include a long-axis blade 1, a medium-axis blade 5, and a short-axis blade 3. These blades are evenly spaced along the circumference of the turntable 7. The different lengths of the long-axis blades 1, 5, and 3 allow for greater relative motion between the slurry particles, increasing the shearing opportunities of the shearing blades and facilitating the rapid decomposition of large organic particles into smaller ones. Furthermore, the different lengths of the long-axis blades 1, 5, and 3 can apply varying degrees of force to the slurry within the same rotation cycle of the turntable 7, thereby achieving a more complex flow pattern. This helps to break up local eddies, promotes slurry exchange over a wider area, and results in more uniform slurry mixing.

[0030] For example, multiple blades of different lengths are arranged regularly along the circumference of the turntable 7. The long-axis blade 1, the middle-axis blade 5, and the short-axis blade 3 are distributed at equal intervals along the circumference of the turntable 7. The long-axis blade 1, the middle-axis blade 5, and the short-axis blade 3 of different lengths and arranged regularly will pass the same position multiple times in the same rotation cycle of the turntable 7, increasing the chance of the slurry being sheared and improving the overall shearing efficiency.

[0031] Specifically, the turntable 7 is provided with multiple fan blades 6, which extend towards the edge of the contour formed by the turntable 7. The fan blades 6 are located close to the axis of the turntable 7 and extend towards the edge of the turntable 7. The turntable 7 drives the fan blades 6 to rotate, so that the slurry located at the axis of the turntable 7 is fully broken down, thereby increasing the breaking down area of ​​the main body 10 and making the slurry break down more thoroughly.

[0032] For example, the blade profile of the fan blade 6 is inclined and forms an angle with the axis of the turntable 7, and the inclination direction of the fan blade 6 is consistent with the rotation direction of the main body 10. When the turntable 7 is working, it drives the angled fan blade 6 to rotate, applying an upward vortex to the slurry, promoting a wider range of slurry mixing, thereby making the slurry mixing more uniform.

[0033] Preferably, the height difference between the highest point of the fan blade 6 (protruding from the surface of the turntable 7) and the lowest point of the fan blade 6 (connected to the surface of the turntable 7) is between 3.5 and 8 cm, thereby increasing the shear force and more effectively decomposing large organic particles into smaller particles, thus improving the quality of the slurry.

[0034] For example, the blade profile of the fan blade 6 has a recess, which forms the bent shape of the fan blade 6. The recess is arc-shaped. When the turntable 7 rotates, the fan blade 6 applies an upward vortex to the slurry. At the same time, the arc-shaped recess can reduce the impact of the slurry and the slurry resistance, and prevent the blade from directly acting on the surface of the fan blade 6 and causing damage to the fan blade 6, thereby extending the service life of the fan blade 6.

[0035] Specifically, the turntable 7 is provided with a plurality of turntable reinforcing plates 4. The turntable reinforcing plates 4 are disposed between two adjacent fan blades 6 and their edges are transitionally connected to the fan blades 6. The turntable reinforcing plates 4 are connected to the turntable 7, the blades, and the fan blades 6 by overlay welding, so as to improve the working performance of the main body 10 and also to improve the service life of the main body 10.

[0036] Specifically, a connecting shaft 8 is vertically arranged along the axial direction of the turntable 7. The turntable 7 has a corresponding shaft hole for the connecting shaft 8, and the connecting shaft 8 is axially fitted onto the shaft hole. The connecting shaft 8 is fitted onto the shaft hole, and its outer wall is connected to the fan blade 6, the turntable 7, and the turntable reinforcing plate 4, respectively, to improve the connection strength between the connecting shaft 8, the fan blade 6, and the turntable 7. The connecting shaft 8 is connected to a drive device to drive the connecting shaft 8 and the turntable 7 to rotate, thereby realizing the slurry disintegration operation.

[0037] Specifically, a shaft cover 2 is provided on the connecting shaft 8. The shaft cover 2 is detachably connected to the connecting shaft. A sealing structure is provided between the shaft cover 2 and the connecting shaft 8 to achieve a seal between the connecting shaft 8 and the shaft cover 2. Preferably, the sealing structure is an upper shaft cover sealing ring 9, which is sandwiched between the connecting shaft 8 and the shaft cover 2. After the shaft cover 2 is connected to the connecting shaft 8, the upper shaft cover sealing ring 9 is compressed and undergoes elastic deformation, allowing the upper shaft cover sealing ring 9 to fit tightly against the shaft cover 2 and the connecting shaft 8, filling the gap between the shaft cover 2 and the connecting shaft 8, thereby achieving a seal between the connecting shaft 8 and the shaft cover 2. This effectively prevents slurry from entering the gap between the connecting shaft 8 and the blade turntable 7, thus ensuring the normal operation of the main body 10.

[0038] The working principle of this embodiment is as follows: the driving device drives the connecting shaft 8 to rotate, and the connecting shaft 8 drives the turntable 7 to rotate, so that the long shaft blade 1, the middle shaft blade 5, and the short shaft blade 3 rotate under the action of the turntable 7. The shearing blades of the long shaft blade 1, the middle shaft blade 5, and the short shaft blade 3 fully break down the slurry, thereby rapidly decomposing large organic particles into smaller particles. When the turntable 7 rotates, the fan blade 6 applies an upward vortex to the slurry, promoting a larger range of slurry mixing, thereby making the slurry mixing more uniform and improving the pulping efficiency.

[0039] Example 2 provides a pulping machine, including a pulping rotor as described in Example 1 above. The pulping machine also includes a machine body and a drive device mounted on the machine body. The drive device is connected to the pulping rotor to drive its rotation. The drive device includes a motor and a transmission mechanism connected to the motor. The transmission mechanism is connected to a connecting shaft 8. After the motor starts, it drives the transmission mechanism to rotate, which in turn drives the connecting shaft 8 to rotate. The connecting shaft 8 then drives the turntable 7 to rotate, causing the long-shaft blade 1, the middle-shaft blade 5, and the short-shaft blade 3 to rotate under the action of the turntable 7. The shearing blades of the long-shaft blade 1, the middle-shaft blade 5, and the short-shaft blade 3 thoroughly break down the pulp, thereby rapidly decomposing large organic particles into smaller particles and improving the quality of the pulp. The transmission mechanism can be a belt drive or a gear drive.
