In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a block diagram showing the structure of the present invention.
Detailed Description
Referring to fig. 1, the technical solution adopted by the present embodiment is: the wood fiber material sequentially passes through the pulper, the high-concentration slag remover, the front buckling pool, the double-disc mill, the rear buckling pool, the slag remover, the pressure screen, the multi-disc thickener, the heat dispersion and the pulp storage tower, and reaches the pulp storage tower through the devices such as the pulper, the high-concentration slag remover, the front buckling pool, the double-disc mill, the rear buckling pool, the slag remover, the pressure screen, the multi-disc thickener and the heat dispersion.
The pulper is used for fully defibering the wood fibers. The wood fiber is fully defibered into waste paper fiber in a pulping machine to form pulp, and the original strength of the fiber is retained to the maximum extent.
The high-concentration slag remover is used for removing heavy impurities with high density and large volume in wood fiber. The wood fiber pulp is purified by the high-concentration slag remover, and impurities such as fragments and stickies with large volume and high density in the wood fiber raw material are removed.
The button front pool is used for storing the defibered wood fiber so as to enter the double-disc grinder at constant pressure. The wood fiber slurry treated by the high-concentration slag separator is stored in the fore-buckling pool, and is pumped to the double-disc mill through the fore-buckling pool discharging pump at constant pressure, so that the stable flow operation is realized.
The double-disc mill is used for pulping the wood fiber, so that the wood fiber is broomed to achieve proper freeness. The wood fiber pulp is beaten between the double-disc grinding disc and the teeth at high speed, so that the wood fiber is broomed to achieve proper freeness.
And the post-buckling pool is used for storing the pulped wood fiber so as to facilitate the constant pressure entering the slag remover. The pulped wood fiber pulp is stored in a post-buckling pool so as to enter a slag remover at a constant pressure.
The slag separator is used for removing heavy impurities with high density and small volume in wood fiber. The wood fiber slurry is purified again by using the slag separator, and heavy impurities with high density and small volume in the wood fiber raw material are removed.
The pressure screen is used for removing the fine impurities with larger volume in the wood fiber. And the wood fiber slurry is purified again by using the pressure screen, so that the small impurities with large volume in the wood fiber are removed.
The multi-disc thickener is used for removing most of water in wood fibers. Most of the water in the wood fiber is removed by using a multi-disc thickener.
The heat dispersion is used for removing impurities such as sizing materials, wax and the like in the wood fiber. After the concentrated waste paper pulp is subjected to heating and dispersion treatment by a heat dispersion machine and a grinding disc of the heat dispersion machine, fine sticky matters in the pulp are dissolved, and the quality of the pulp is improved.
