Embodiment Construction
[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0039] refer to Figure 1-7 , a pollution-free production process of plant fiber pulp, comprising the following steps:
[0040] Step S1, in the upper cylinder 4, send the peeled, knotted and washed logs to the equipment for crushing, and spray 1-3 parts of pure water to the logs in the equipment every 5-10 minutes. Humidity, to ensure the structural hardness of the logs to be able to be chopped;
[0041]In step S2, the shredded logs are moved into the lower cylinder 3 under the action of gravity, and the shredded logs are pressed for 1-1.5 hours, and 1.5-2 parts of the logs are sprayed every 25-30 minutes. alkaline solution;
[0042] Step S3, screening the dried l...

The invention discloses a pollution-free production process of plant fiber pulp and its production equipment. The production process comprises the following steps. According to the pollution-free production process of plant fiber pulp, the present invention respectively sets a pretreatment mechanism and a deep treatment mechanism with an integrated structure; in the pretreatment mechanism, a rotating crushing knife is used to carry out deep shearing of logs; and the main crushing mill and auxiliary crushing mill are used to Separation and distinction of acid-leached log residue and slurry; in the deep treatment mechanism, the cooking box is used to preheat the paddles in the pulping box; by adding additives in the slurry and drying cylinder coating agents in the cooling state, In order to improve the softness and smoothness of the slurry, and at the same time improve the brightness and cleanliness of the pulp; by adding a protease aqueous solution that is highly mixed with the slurry, it is easy to treat the lignin, resin, pigment, pectin and The ash and the like are separated and cleaned to obtain highly refined seminal plasma.
Description
technical field [0001] The invention relates to the technical field of fiber pulp, in particular to a pollution-free production process and production equipment for plant fiber pulp. Background technique [0002] As the country of origin of papermaking, my country has been tirelessly exploring papermaking technology. In any age, due to the needs of cultural development, paper manufacturing as a cultural carrier can become an industry that will never decline, and it is also a pillar industry of my country's national economy. But it has to be admitted that the papermaking industry is an important aspect of environmental pollution because of the wide variety and quantity of materials required for papermaking, especially the necessary sources of pulp for papermaking are various plants. [0003] Because the traditional technology mostly adopts the method of directly crushing and pressing plants, but the structure of the plant fiber itself is tough, and the pulp can be completely o...
