Embodiment Construction

[0050] Please refer to Fig. 1, the present invention proposes a kind of manufacturing method that cassava root material makes paper pulp, and it comprises the following steps:

[0051] Step 1, HD (hydra pulper) step: mix the raw material with water, the raw material is cassava root, keep its concentration and proportion at about 4-10%, the above ratio is the weight ratio, and then enter the next step;

[0052] Step 2. HC (high consistency cleaner) separation step: separate the impurities whose specific gravity is greater than that of pulp, such as sand, stone and others, and separate them with a concentration of 4-10% before proceeding to the next step;

[0053] Step 3, FF (fiber fretter) step: separating the pulp, distinguishing the long-fiber pulp and the short-fiber pulp, and then respectively entering the next step with the separated long- and short-fiber pulp;

[0054] Afterwards, the long and short fiber pulp will be separated into the respective steps:

[0055] Wherein...

Abstract

The invention relates to a method used for preparing pulp by using tapioca root, which is characterized in that steps DS and FS are not used before the separation of short fibered pulp and long fibered pulp, and long fibered pulp goes through the step RF in advance, then goes through the steps which are the same as short fibered pulp. By adopting the tapioca root as raw material, the production cost is reduced, the tapioca root is found more easily, more materials can be selected during production, and higher-quality paper can be obtained because the leftover starch in tapioca root can tighten the fiber in the pulp and more completely fill the microcosmic gap.

Description

technical field [0001] The invention relates to a method for manufacturing pulp, in particular to a method for manufacturing pulp from cassava root materials with low cost and good pulp quality. Background technique [0002] The raw material used in the traditional pulp manufacturing industry is shredded paper, which is manufactured according to the following steps: [0003] 1. HD (hydra pulper) step: mix the raw material with water, here the raw material is shredded paper, keep its concentration and proportion at about 4-10%, and then enter the next step; [0004] 2. DS (drum sorter) step: separate the impurities, such as plastic, rope, stone, iron, etc. to separate the pulp, and then enter the next step; [0005] 3. HC (high consistency cleaner) separation step: separate the impurities whose specific gravity is greater than that of pulp, such as sand, stone and others, and separate them with a concentration of 4-10% before entering the next step; [0006] 4. FS (fiber so...
