Grinding device and process for the development of water-resistant and oil-proof paper

Abstract

The invention discloses a grinding device used for grinding water-resistant oil-proof paper. The grinding device used for grinding the water-resistant oil-proof paper comprises a shell, wherein a detachable grinding device is arranged on the shell, the detachable grinding device comprises grinding disks, clamping parts, rotating shafts, servo motors, a feeding pipe, a stirring part and a feeding shell, the two grinding disks are symmetrically arranged in the shell, and the sides, away from each other, of the two grinding disks are movably connected with the rotating shafts through the clampingparts respectively. According to the grinding device used for grinding the water-resistant oil-proof paper, through the grinding disks and the rotating shafts which are connected through the clampingparts, detaching and installation of the grinding disks are facilitated, meanwhile, by arranging a filter screen on a discharging shell of pulp, through the filter screen, the pulp which is ground poorly is separated out, through limiting discharging parts, the pulp which is ground poorly is discharged, and then the grinding precision is improved, and the pulp grinding efficiency is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of water-resistant and oil-proof paper, in particular to a grinding device for the development of water-resistant and oil-proof paper and a process thereof. Background technique [0002] Water-resistant and oil-proof paper, in a broad sense, refers to paper that can prevent oil absorption and penetration. In a narrow sense, it refers to a type of paper that is made of bleached, semi-bleached or unbleached chemical wood pulp through high beating degree treatment. Including paper grades that can resist oil penetration and absorption produced by adding oil repellents in pulp or surface coating. [0003] In the process of developing the existing water-resistant and oil-proof paper, the slurry is often polished with a double-disc refiner. However, during the grinding process of the slurry, there is no separation device at the outlet, resulting in insufficient grinding. Slurry is often discharged along the discha...

AI Technical Summary

Problems solved by technology

[0003] In the process of developing the existing water-resistant and oil-proof paper, the slurry is often polished with a double-disc refiner. However, during the grinding process of the slurry, there is no separation device at the outlet, resulting in insufficient grinding. Slurry is often discharged along the discharge port, resulting in insufficient grinding of the slurry, reducing the grinding accuracy of the slurry, and the long-term use of the grinding disc in the disc refiner is easy to cause wear and tear, and the existing grinding blades are not easy to replace , and then reduce the grinding efficiency. Therefore, we propose a grinding device and its process for the development of water-resistant and oil-proof paper
