Description

Technical Field

[0001] The utility model belongs to the technical field of pulp fiber dispersion, in particular to a pulp fiber dispersion device. Background Art

[0002] In the papermaking industry, pulp uniformity is crucial to ensuring the quality and performance of the final product. While existing pulp mixing equipment can achieve a certain degree of mixing, it commonly suffers from issues such as inadequate mixing, high energy consumption, and high maintenance costs. These issues not only limit production efficiency but also increase production costs. Common pulp mixing equipment on the market today is primarily mechanical and air flow. Mechanical mixing uses rotating blades to achieve mixing. While simple and easy to use, it can easily cause clumping when handling materials with high viscosity or long fibers, and consumes a lot of energy. Air flow uses high-pressure gas to propel the pulp. While this method effectively avoids clumping, the presence of bubbles can affect pulp quality, and large-scale production lines require significant energy consumption. Neither mechanical nor air flow mixing fully meets the requirements for high efficiency and energy conservation, particularly when handling different pulp types. Furthermore, both methods require regular cleaning of the equipment to prevent residue from clogging or contaminating the finished product, which significantly increases maintenance workload and costs. Very few existing pulp fiber dispersion technologies provide high-temperature heating and stirring, and different stirring methods are not easy to disperse the pulp fibers. Utility Model Content

[0005] In this technical solution, pulp is added to a mixing tank, where the stirring assembly stirs the pulp, and the heater heats the pulp within the tank. The fibers within the pulp are not yet fully dispersed, but repeated stirring disperses them. The heater raises the temperature within the tank, aiding in the dispersion of the fibers.

The lid 4 is detachably fixed to the top of the mixing tank 3, which not only allows for quick addition of pulp but also improves the sealing and thermal insulation of the interior of the mixing tank 3. When the temperature rises, heat is not easily lost, reducing energy consumption and improving production efficiency.

[0041] like Figure 2-5As shown, the stirring assembly 5 includes a first motor 18, which is fixedly mounted on a first mounting bracket 25.

A stirring drum 15 is fixedly provided at the bottom of the first stirring rod 13. The stirring drum 15 is coaxially fixedly connected to the first transmission shaft 14. The sealed cylinder 11 and limiting cylinder 12 provide a fixed position for the stirring rod without reducing the airtightness of the mixing tank 3. The first transmission shaft 14 drives the stirring rod to rotate with the first transmission shaft 14 as the central axis, and the stirring drum 15 also rotates. The stirring drum 15 has the main stirring function, and the stirring rod assists the stirring drum 15.

[0043] like Figure 3 As shown, holes 16 are provided on the outer wall of the mixing drum 15, and stirring blades 17 are arranged in a circumferential array on the outer wall of the mixing drum 15. The holes 16 on the mixing drum 15 are conducive to the fluidity of the pulp during stirring, and the stirring blades 17 on the mixing drum 15 improve the stirring effect.

[0045] like Figure 7As shown, a temporary storage assembly is also included, which includes a third mounting frame 7, which is fixedly mounted on the first mounting frame 25. A storage tank 6 is installed on the third mounting frame 7. A first pipe 9 is fixed to the bottom of the storage tank 6. The first pipe 9 is connected to the mixing tank 3 via a second pipe 8. A flow assembly is connected to the bottom of the first pipe 9, and the flow assembly is connected to the mixing tank 3 via a third pipe 10. During the mixing process, the mixing tank 3 is heated, and the pulp inside may expand due to heat. To prevent the mixing tank 3 from being affected by the heated expansion of the pulp, excess pulp enters the storage tank 6 through the second pipe 8. The flow assembly transports the pulp in the storage tank 6 to the mixing tank 3 through the third pipe 10, allowing the excess expanded pulp to circulate between the mixing tank 3 and the storage tank 6, thereby preventing the pulp remaining in the storage tank 6 from being processed.

[0046] like Figure 7 As shown, the flow assembly includes a second motor 21, which is fixedly mounted on the base 1.
