Description

Technical Field

[0001] This utility model relates to the field of pulverizing equipment technology, specifically a homogenizing pulverizer. Background Technology

[0002] In the field of crushing equipment technology, traditional equipment such as roller crushers and swivel crushers have many significant drawbacks: they rely on screens or gravity to control particle size, resulting in uneven particle size distribution and mixing of fine particles with long fibers, severely affecting product quality consistency; they also require repeated crushing to achieve uniform particle size, leading to high energy consumption per unit capacity, severe over-crushing, and high production costs; simultaneously, horizontally arranged crushing devices are difficult to effectively handle straw in different directions, vertical conveying results in poor chopping, disordered straw requires manual intervention in the feeding sequence, and they are not adaptable to flexible / semi-flexible materials. In addition, traditional equipment experiences high temperature rise during the crushing process, which can easily cause denaturation or loss of effective components in heat-sensitive materials. With the increasing demand for nanoscale homogenization in the agricultural straw resource utilization (such as biomass fuel and feed) and the pharmaceutical and food industries, existing equipment can no longer simultaneously address particle size uniformity, energy consumption, and applicability. Therefore, this project was developed to address these issues through in-depth research. Utility Model Content

[0013] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0015] Please see Figure 1-2 Uneven particle size control: Existing equipment (such as roller cutter and swivel cutter crushers) relies on screen plates or gravity to control particle size, resulting in uneven particle size distribution and mixing of fine particles with long fibers, affecting product quality consistency; Low energy efficiency: Traditional equipment requires repeated crushing to achieve uniform particle size, resulting in high energy consumption per unit capacity and serious over-crushing, increasing production costs; Structural limitations: Horizontally arranged crushing devices (such as roller cutter + swivel cutter combination) cannot effectively handle straw in different directions, and vertically conveyed straw has poor chopping effect, requiring manual intervention in the feeding sequence; Therefore, this application protects a homogenizing pulverizer. Raw materials fall into the inner side of the feeding cylindrical box 3. The feeding drive 17 operates, driving the feeding shaft 5 on the drive end of the feeding drive 17 to rotate. The feeding shaft 5 drives the feeding partition plate 6 and the sealing arc plate 7 on it to divide the inner side of the feeding cylindrical box 3 into multiple rotating sealed spaces. The raw materials are pushed into the inner side of the collecting and diverting pipe 4. The pulverizing drive operates, driving the pulverizing gear set on the drive end of the pulverizing drive. The pulverizing gear set drives a pair of large pulverizing rollers 8 and a pair of small pulverizing rollers 9 to rotate. The pulverizing rollers then compress the raw materials in pairs. The crushed material is initially filtered by the inclined guide plate 10. Material larger than the inclined guide plate 10 falls into the inner side of the filter concave agglomeration block 12. The material is guided to the inner side of the U-shaped upward guide pipe 14 by a pair of triangular guide blocks 13 on the inner side of the filter concave agglomeration block 12. The feeding drive machine 17 runs, which drives the feeding screw shaft 15 on the drive end of the feeding drive machine 17 to rotate. The feeding screw shaft 15 drives the screw blades 16 on it to rotate. The screw blades 16 lift the material in a screw, thereby guiding the material back to the agglomeration guide pipe 4 for cyclic crushing and grinding. In summary, during the feeding stage, the raw material falls into the inner side of the feeding cylindrical box 3. The feeding drive 17 starts, driving the feeding shaft 5 at its drive end to rotate. This causes the feeding partition plate 6 and the sealing arc plate 7 on the feeding shaft 5 to rotate, dividing the inner side of the feeding cylindrical box 3 into multiple rotating sealed spaces. As they rotate, the raw material is quantitatively and orderly pushed to the collecting and diverting pipe 4, and finally transported to the crushing box 2. This design avoids a large influx of raw material at once, ensuring the stability and continuity of the crushing process. In the initial crushing stage, the crushing drive operates, driving the crushing gear set at its drive end to rotate, thereby driving a pair of large crushing rollers 8 and a pair of small crushing rollers 9 to rotate. After the raw material enters the crushing box 2, it is subjected to paired compression between the large and small crushing rollers 9. The large crushing rollers 8 first perform preliminary crushing of larger pieces of raw material, and the small crushing rollers 9 further refine the crushing. This combination of crushing rollers of different sizes improves the crushing efficiency. In the preliminary filtration stage, the pulverized raw material falls onto a pair of inclined guide plates 10 arranged in a crisscross pattern below the large and small pulverizing drums 9. Utilizing the inclination angle and gap setting of the inclined guide plates 10, raw materials smaller than the gap pass through, while those larger fall into the inner side of the filter concave agglomerating block 12, achieving preliminary screening, separation, and grading of the raw materials. For unqualified raw materials, in the unqualified raw material return stage, a pair of triangular guide blocks 13 inside the filter concave agglomerating block 12 guide the fallen raw material to the inner side of the U-shaped upward guide pipe. Another matching feeding drive 17 drives the feeding spiral shaft 15 at its drive end to rotate, thereby causing the spiral blades 16 to rotate. Using the lifting force generated by the rotation of the spiral blades 16, the unqualified raw material is spirally lifted and re-guided to the agglomerating guide pipe 4 and returned to the pulverizing box 2 for cyclic pulverization and grinding, ensuring the uniformity of the final product particle size. Finally, during the unloading stage, after multiple cycles of crushing and grinding, once the raw material reaches the required particle size, the unloading valve on the bottom collection and diversion pipe 4 of the crushing box 2 is opened. By setting the unloading valve, the qualified raw material can be discharged in a controlled manner. During equipment operation, the unloading valve is closed to ensure that the raw material is fully crushed. Once the requirements are met, the valve is opened to complete the unloading operation.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
