Description

Technical Field

[0001] The utility model relates to the technical field of refined cotton processing, in particular to a refined cotton pulping device. Background Art

[0002] Refined cotton is a high-purity cellulose product obtained by refining cotton linters through alkaline cooking, rinsing and other refining treatments. It is non-toxic, odorless, and easy to absorb water. It is the main raw material for the manufacture of ether cellulose, nitrocellulose and cellulose acetate.

[0003] During the refined cotton production process, the material cut from the product needs to be pulped and recycled. Due to the compact structure of the refined cotton after crushing, it needs to be dissolved in water and pulped through a pulping device before it can be used as raw material for further production. Currently, during the pulping process, the material is poured into an outer barrel and pulped by a high-speed rotating pulping roller. After the barrel of material is pulped, the discharge valve is opened to discharge the pulp. This pulping method pulps the material barrel by barrel, resulting in low pulping efficiency and inability to achieve continuous pulping. To address this situation, we have proposed a refined cotton pulping device. Utility Model Content

[0019] Depend on Figure 1 、 Figure 2 and Figure 3As shown, the refined cotton pulping device includes an outer barrel 1, a pulp baffle 2, a pulping barrel 3, a pulping roller 4, a pulping motor 5 and a pulp discharge pipe 6. The interior of the outer barrel 1 is in a cavity shape, and a plurality of support columns 12 are provided at the bottom of the outer barrel 1. The pulp baffle 2 is fixedly installed in the outer barrel 1 in an annular shape, and a pulp discharge groove 7 is left between the pulp baffle 2 and the inner wall of the outer barrel 1. The pulping barrel 3 is fixedly installed in the outer barrel 1, and the pulping barrel 3 is located on the inner side of the pulp baffle 2. A pulp discharge groove 8 is left between the pulping barrel 3 and the pulp baffle 2, and a filter screen 13 is provided at the lower end of the pulping barrel 3. The pulp baffle 2 is higher than the filter screen 13 at the lower end of the pulping barrel 3. The pulping roller 4 is rotatably installed in the pulping barrel 3, and the pulping roller 4 is provided with crushing rods distributed in a tower shape. 9. A retaining frame 10 is provided at the upper end of the pulping barrel 3, and the retaining frame 10 is rotatably connected to the upper end of the pulping roller 4. A fan-shaped pulp turning plate 11 is fixedly installed at the lower end of the pulping roller 4. By setting the fan-shaped pulp turning plate 11, the deposited refined cotton pulp that has not passed through the filter 13 at the bottom is turned up to the upper side of the pulping roller 4. The pulping motor 5 is fixedly installed on the lower end surface of the outer barrel 1. The pulping motor 5 is transmission-connected to the pulping roller 4. The paired pulp discharge pipes 6 are respectively fixedly installed on the lower end surface of the outer barrel 1.
