Description

Technical Field

[0001] This utility model relates to the field of pulp manufacturing technology, and in particular to a wood grinding device for pulp manufacturing. Background Technology

[0002] In the pulp manufacturing industry, grinding wood is a key step in pulp production. Traditional grinding wood equipment used in pulp manufacturing faces many problems in actual operation, especially the blockage problem in the feeding stage, which seriously affects production efficiency and product quality.

[0003] Currently, most wood grinding devices place the crushed wood directly into the feed hopper during feeding, and then rely on gravity to allow the raw material to fall naturally into the mixing mill for processing. However, the crushed wood often contains wood chips, fragments, and other particles of different sizes. During the falling process, these particles are prone to mutual compression and accumulation, leading to blockage in the feed hopper. Once blockage occurs, not only will the raw material be unable to enter the mixing mill smoothly, reducing production efficiency, but it may also cause the mixing mill to run idle, increasing equipment wear and energy consumption.

[0004] However, manually cleaning the hopper blockage not only consumes a lot of time and manpower, but also interrupts the production process and affects the continuity of the entire pulp manufacturing. In addition, frequent clogging and cleaning operations may damage the hopper and related components, shorten the service life of the equipment, and increase the production cost of enterprises. Therefore, there is a need for a wood grinding device that can effectively prevent hopper blockage and ensure that the crushed wood and other raw materials can smoothly enter the mixing and grinding mill. Utility Model Content

[0005] Given that manually cleaning the hopper blockage not only consumes a lot of time and manpower, but also interrupts the production process and affects the continuity of the entire pulp manufacturing, and that frequent blockage and cleaning operations may damage the hopper and related components, shorten the service life of the equipment, and increase the production cost of the enterprise, there is a need for a wood grinding device that can effectively prevent hopper blockage and ensure that the crushed wood and other raw materials can smoothly enter the mixing and grinding mill. This utility model is proposed.

[0006] Therefore, the purpose of this utility model is to agitate the raw materials such as crushed wood after they are put into the feed hopper by rotating agitating claws. On the one hand, the rotation of the agitating claws can break the compression and accumulation between the raw materials, prevent sawdust and fragments from clogging each other, and allow the raw materials to move smoothly into the mixing mill below. On the other hand, the rotation of the agitating claws can also play a certain pushing role, speeding up the speed at which the raw materials enter the mixing mill, thereby increasing the production efficiency.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a wood grinding device for pulp manufacturing, including a grinding fixed base 1 and a support connecting block 2 on one side of the grinding fixed base 1. A mounting connecting block 3 is provided on one side of the support connecting block 2. A mixing grinding machine 4 is provided on one side of the grinding fixed base 1. A feeding hopper 5 is provided on one side of the mixing grinding machine 4. The device includes a fixed motor 15 mounted on the mounting connecting block 3. A rotating stirring rod 14 is provided on one side of the fixed motor 15. A plurality of upper rotating constraint grooves 22 are provided on the rotating stirring rod 14. A ring constraint block 16 is provided on the plurality of upper rotating constraint grooves 22. A triangular support block 21 is provided on one side of the mounting connecting block 3. One side of the triangular support block 21 is connected to the support connecting block 2. A sealing connecting plate 6 is provided on the outside of the feeding hopper 5.

[0033] Multiple rotation constraint grooves 7 are provided on the feed hopper 5. A rotation connecting column 11 is provided inside each rotation constraint groove 7. Multiple fixed connecting columns 9 are provided on one side of the sealing connecting plate 6. A rotating gear 10 is provided on one side of each fixed connecting column 9. Each rotating gear 10 is connected to the rotation connecting column 11 on one side. A rotation mounting groove 8 is provided on the feed hopper 5. An annular mounting block 17 is provided on the outer side of the annular constraint block 16.

[0034] Example 2

[0035] Reference Figure 4-6 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that it includes multiple rotating connecting columns 11 installed on the feed hopper 5, each rotating connecting column 11 having a rotating connecting plate 12 on one side, each rotating connecting plate 12 having multiple stirring claws 13 on one side, an annular mounting block 17 being disposed inside the rotating mounting groove 8, an annular toothed plate 18 being disposed outside the annular mounting block 17, the annular toothed plate 18 being disposed between the feed hopper 5 and the sealing connecting plate 6, and each rotating gear 10 meshing with the annular toothed plate 18.

[0036] The feed hopper 5 has a lower rotation constraint groove 19 and an upper rotation constraint groove 22. The lower rotation constraint groove 19 and the upper rotation constraint groove 22 are respectively connected to the rotation mounting groove 8. The two ends of the annular constraint block 16 are respectively located inside the lower rotation constraint groove 19 and the upper rotation constraint groove 22. A fixed water tank 23 is provided on one side of the mounting connecting block 3, and a fixed water pipe 20 is provided on one side of the fixed water tank 23. One end of the fixed water pipe 20 passes through the mounting connecting block 3 and is inserted into the inside of the feed hopper 5.

[0037] When in use, start the fixed motor 15 installed on the mounting connection block 3. The fixed motor 15 starts working and drives the rotating stirring rod 14 on one side to rotate. The rotating stirring rod 14 is provided with multiple upper rotation constraint grooves 22. The annular constraint block 16 is installed on these upper rotation constraint grooves 22. As the rotating stirring rod 14 rotates, the annular constraint block 16 will also rotate.

[0038] An annular mounting block 17 is provided on the outer side of the annular constraint block 16. Due to the rotation of the annular constraint block 16, the annular mounting block 17 and the annular toothed plate 18 are rotated together. A rotating gear 10 is provided on the fixed connecting column 9 on one side of the sealing connecting plate 6. The rotating gear 10 meshes with the annular toothed plate 18, so the rotation of the annular toothed plate 18 will drive the rotating gear 10 to rotate, thereby driving the rotating connecting plate 12 and the stirring claw 13 to rotate together.

[0039] After the crushed wood and other raw materials are put into the feed hopper 5, the rotating agitator 13 will agitate the raw materials. On the one hand, the rotation of the agitator 13 can break the compression and accumulation between the raw materials, avoid the blockage of wood chips and fragments, and allow the raw materials to move smoothly to the mixing mill 4 below. On the other hand, the rotation of the agitator 13 can also play a certain pushing role, speeding up the speed at which the raw materials enter the mixing mill 4.

[0040] The fixed water tank 23 on one side of the mounting connecting block 3 supplies water to the feed hopper 5 through the fixed water pipe 20. Water flows into the feed hopper 5 from one end of the fixed water pipe 20. During the feeding process, the water mixes with the raw materials. The addition of water can not only play a lubricating role and reduce the friction between the raw materials and between the raw materials and the inner wall of the feed hopper 5, but also help the raw materials enter the mixing mill 4 more smoothly. At the same time, the water can also initially wet the raw materials, preparing them for the subsequent grinding work in the mixing mill 4, thereby improving the grinding efficiency and quality.

[0041] The remaining structure is the same as that in Example 1.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
