Embodiment 1

[0014] as attached figure 1 Shown: an improved high-concentration hydraulic pulper, including: a pulper tank 4, a motor 1, a transmission device 2, a transmission shaft 8, blades 3, an anti-deflection sealing device 5 and a joint bearing 6, wherein the The motor 1 and the transmission device 2 are located at the top of the outside of the pulper tank 4, the pulper tank 4 is a cylindrical tank, and the blade 3 is spirally mounted on the transmission shaft 8, The diameter of the blades 3 gradually increases from top to bottom, and every two blades 3 form a group, and a gap is provided between each group to reduce resistance. The gap is 10-50 cm, and the anti-deflection The sealing device 5 is located at the bottom inside the pulper tank 4 , and the joint bearing 6 is located at the bottom outside the pulper tank 4 .

Embodiment 2

[0016] On the basis of embodiment 1, the preferred embodiment of the present invention is, described blade 3, further be the blade 3 of ellipse, the quantity of blade 3 is 2 groups, and the distance between each group is 40cm, all the other structure and implementation Example 1 is exactly the same.

Embodiment 3

[0018] On the basis of embodiment 1, the preferred embodiment of the present invention is, described blade 3, further be the blade 3 of ellipse, the quantity of blade 3 is 3 groups, and the distance between each group is 30cm, all the other structure and implementation Example 1 is exactly the same.

Abstract

The invention relates to a high-consistency hydropulper. The high-consistency hydropulper comprises a pulper tank body, a motor, a transmission device, a transmission shaft, blades, an anti-deflectionseal device and a joint bearing, wherein the motor and the transmission device are located at the top end of the exterior of the pulper tank body which is a cylindrical tank body; the blades are spirally arranged on the transmission shaft; the diameters of the blades are gradually increased from top to bottom; every two blades form a group, and a gap is arranged between every two groups for reducing of resistance; each gap is 10 to 50 cm; the anti-deflection seal device is located at the bottom part of the interior of the pulper tank body; and the joint bearing is located at the bottom end ofthe exterior of the pulper tank body. The high-consistency hydropulper provided by the invention needs small power due to spiral distribution of the blades.

Description

technical field [0001] The invention relates to the field of papermaking machinery, in particular to a high-concentration hydraulic pulper. Background technique [0002] The high-consistency hydraulic pulper is mainly used for deinking pulping of waste paper such as waste newsprint, waste books and periodicals, and graphic newspapers. Under the condition of high concentration and heating, waste paper is shredded and chemicals such as deinking agent are added at the same time, which can give full play to the comprehensive effect of mechanical friction, rubbing and chemical additives, so that impurities such as ink particles can be separated from fibers quickly, and then combined with subsequent sections The advanced flotation, washing, purification and other treatments can effectively remove impurities such as ink particles and produce pulp with considerable whiteness. The pulper in the prior art mainly includes a tank body, a rotor, and a transmission device, which is a low...
