Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmentally friendly lunch box preparation and processing technology, specifically to a high-efficiency stirring and dispersing equipment for fiber raw materials. Background Technology
[0002] Eco-friendly lunch boxes refer to food containers made of materials that are harmless, non-toxic, odorless, and easily degradable. Their production, use, and disposal processes are pollution-free, and the product quality fully meets national food hygiene requirements. They are also easy to recycle, dispose of, or dispose of after use. In the production of pulp eco-friendly lunch boxes, stirring and dispersing the fiber raw materials is the core process, which directly affects product quality, production efficiency, and environmental performance.
[0003] The "Dispersion Device for Papermaking" disclosed in application number "201921243685.7" includes a cylinder with two vertically rotating stirring shafts symmetrically arranged inside. Each shaft has multiple sets of stirring rods arranged vertically on its shafts, each set containing at least two stirring rods. The ends of the stirring rods away from the stirring shafts are inclined upwards or downwards, with the same direction of inclination for stirring rods within the same set, and opposite directions for adjacent stirring rods. A U-shaped rotating rod is rotatably mounted at the bottom of the cylinder, with several stirring support rods on its horizontal portion. A scraper is mounted on the vertical portion of the rotating rod near the inner wall of the cylinder, abutting against the inner wall. A heating and insulation device is mounted on the outer wall of the cylinder. This invention utilizes dual stirring shafts for stirring, improving the dispersion range and efficiency. The opposite inclination directions of adjacent stirring rod sets create interlayer convection, further enhancing the dispersion effect. The stirring support rods and scrapers on the rotating rod can clean the inner wall and bottom of the cylinder, ensuring the quality of pulp dispersion.
[0004] However, the above method still has the following drawbacks: setting two sets of stirring rods can disperse the pulp fibers, but it will form a unidirectional flow, which is easy to create blind spots. In addition, the cylinder is relatively closed, which makes it inconvenient to feed and unload the pulp, and also makes it inconvenient to maintain and repair the inside of the cylinder. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a high-efficiency stirring and dispersing device for fiber raw materials, which has the advantages of generating a symmetrical vortex field, improving shearing efficiency, and being less prone to blind zones, thus solving the problems mentioned in the background technology.

The reverse drive assembly can drive the two stirring shafts to rotate in opposite directions. The stirring shafts can stir the pulp in different directions through the dispersing rod, which can generate a symmetrical vortex field. The relative velocities can be superimposed, making it less likely to generate a stirring blind zone and improving the shearing efficiency of the fiber raw materials in the pulp. The support shaft can provide stable support for the bottom of the stirring shaft, which can maintain the stability of the stirring shaft during the stirring of pulp fibers inside the dispersing tank and prevent the stirring shaft from shaking.
[0016] 2. The top of the dispersion tank is open, which ensures operating space, facilitates maintenance and repair of the dispersion tank, and facilitates the feeding of pulp. The dispersing tank can be locked by the flipping component, which can prevent the dispersion tank from rotating when stirring and dispersing the fiber raw materials in the pulp. The dispersion tank can also be flipped after stirring the pulp. The guide plate and guide channel can guide the pulp flow, which can facilitate the centralized discharge of the pulp through the guide channel. Attached Figure Description

The support shaft 7 can provide stable support for the bottom end of the stirring shaft 5.
[0029] In use, pulp is first fed into the dispersion tank 2 through the opening at the top of the dispersion tank 2. The worm 302 of the flipping component 3 can achieve self-locking of the support column 4 through the angular friction between it and the worm wheel 303, which can prevent the dispersion tank 2 from rotating randomly. Then, the motor 904 of the reverse drive component 9 drives the drive shaft 903. Two gears 905 can make one of the stirring shafts 5 and the drive shaft 903 rotate in opposite directions. The sprocket 906 and the chain 907 can make the other stirring shaft 5 rotate in the same direction as the drive shaft 903. The two stirring shafts 5 can rotate in opposite directions. The stirring shaft 5 can stir the pulp in different directions through the dispersion rod 6, which can generate a symmetrical vortex field. The relative velocities can be superimposed, and it is not easy to generate a stirring blind zone, which can improve the shearing efficiency of the fiber raw materials in the pulp.
[0030] During the pulp mixing process, the support shaft 7 provides stable support to the bottom of the mixing shaft 5, maintaining the stability of the mixing shaft 5 and preventing it from shaking. After the fiber raw materials in the pulp are dispersed by mixing, the worm gear 302 is driven by the motor 304. The worm gear 302 drives the support column 4 to rotate through the worm wheel 303, which increases the torque. The support column 4 drives the dispersion tank 2 to rotate and flip it. The guide plate 15 and the guide channel 16 can guide the pulp flow, and the pulp can be discharged in a concentrated manner through the guide channel 16. After the pulp is discharged, the motor 304 drives the worm gear 302 in the reverse direction to reset the dispersion tank 2, which can repeat the pulp mixing activity.
