Problems solved by technology

[0003] In use, it was found that the cylinder deflaker only uses the shear force generated by the falling of the pulp to decompose the waste paper, and the efficiency is low, and sometimes the large waste paper group cannot be completely deflagrated, so it is discharged as waste residue, causing waste of raw materials

Embodiment 1

[0015] Embodiment 1: As shown in Figure 1, the horizontal rotary cylinder deflaker includes a deflaker cylinder, and the decompressor cylinder is divided into a pulping zone cylinder 1 and a screening zone cylinder 6, and the pulping zone A partition 2 is provided on the inner wall of the cylinder 1 , and loosening teeth 3 are provided at the end of the partition 2 . The cylinder 1 in the pulping area and the cylinder 6 in the screening area are integrated structures in the prior art. The working principle of the cylinder in the screening area of ​​the cylinder is that the surface of the cylinder is processed with screening holes. After the waste paper is decomposed in the pulping area, it enters the screening area with holes in the surface of the cylinder. Here, the pulp is diluted. Sparse water is added from the water spray device installed above the screening area, so that the fibers blocked in the screen holes can be recoiled back into the cylinder, the good pulp flows int...

Embodiment 2

[0017] Embodiment two: as shown in Fig. 2, Fig. 3, horizontal rotary cylinder deflagging machine, comprises deflagging machine cylinder, and described deflagging machine cylinder is divided into crushing zone cylinder 1 and screening zone cylinder 6, described A baffle 2 is provided on the inner wall of the cylinder 1 in the pulping area, and loosening teeth 3 are provided at the end of the baffle 2 . The cavity of the cylinder 1 in the pulping area is provided with a "D"-shaped drum core 4 arranged axially in the pulping area of ​​the cylinder. The circular surface of the "D"-shaped drum core 4 is located in the rising area of ​​the waste paper cluster. The "D" shaped drum core 4 is also provided with loosening teeth 5 . The cylinder 1 in the pulping area and the cylinder 6 in the screening area are separated, and the cylinder 6 in the screening area is a cylindrical screen. This structure can make the cylinder 1 in the pulping area and the cylinder in the screening area 6. ...

Abstract

This invention discloses a level rotation cylinder clear out machine. It divide into the pulping area and the screening area. The pulping area cylinder's wall is equipped with the partition board, the partition board's end is equipped with clears out tooth. The waste balled paper pocketed by the partition board and move to cylinder's upside willfall down according to the gravity and the inertia. At this time the partition board's clear out tooth tear the balled paper, causes the waste balled paper to launch and fall; When falls to the base, the base partition board clears out the tooth further decompose the scrap paper; This invention strengthen the cylinder cleared out machine's ability, the structure is simple, clears out the efficiency is enhance above 30%.

Description

technical field [0001] The invention relates to a papermaking machine, in particular to a cylinder fluffing machine. Background technique [0002] The advantage of the drum deflaker is that it decomposes waste paper fibers without shredding waste and producing fine fibers, without consuming unnecessary stirring, cutting fibers and impurities, and lower energy consumption; its cylinder includes crushed The pulping area and screening area, the working principle of the pulping area is shown in Figure 4. The waste paper entering the pulping area is soaked by water and chemicals. Because the cylinder is slightly inclined, the waste paper moves forward slowly by gravity. The partition on the inner wall of the cylinder continuously picks up the waste paper and drops it to the bottom of the cylinder at a certain height, and uses the shearing force to loosen the fibers of the waste paper without breaking the waste. [0003] In use, it was found that the cylinder deflaker only uses t...
