Embodiment 1

[0021] Put a kind of traditional Chinese medicine or traditional Chinese medicine residue left after decocting or leaching into the steaming ball. In this embodiment, it is the freshly extracted Tripterygium wilfordii medicine residue. Because of the large water content, the ratio of solid to liquid is 1: 1 Add water. After filling, open the steam valve to pass steam into the steam ball, when the temperature rises to 110°C, the pressure rises to 3kg / cm 2 , close the steam inlet valve, and then heat and cook for 1 hour. Thereafter, open the steaming gate, unload the steamed material, and send the steamed material of medicinal residue to the high-consistency refiner through the conveyor belt to obtain coarse pulp. The coarse pulp obtained is screened and washed to obtain fine pulp. The fine pulp is transferred into the pulp conditioning box, and the pulp suitable for preparing corrugated paper and packaging paper is obtained through pulp conditioning. The sediment produced du...

Embodiment 2

[0023] Put a kind of traditional Chinese medicine or traditional Chinese medicine compound into the steamer after decocting or leaching the remaining Chinese medicinal residues. In this example, it is the dried medicinal residues of sargassum after extraction. Because the water content is small, the ratio of solid to liquid is 1 : 3 add water. After filling, start atmospheric pressure cooking, cooking temperature is 90~100 ℃, time is 4 hours. After that, the steamed material is taken out, and the steamed material of the medicine dregs is sent to the high-consistency refiner through the conveyor belt to obtain coarse pulp. The coarse pulp obtained is screened and washed to obtain fine pulp. The fine pulp is transferred into the pulp conditioning box, and the pulp suitable for preparing corrugated paper and packaging paper is obtained through pulp conditioning. The sediment produced during screening and washing is dried and used as organic or inorganic fertilizer or animal fee...

Abstract

The inventive Chinese medicine dregs used as paper-making pulping raw material pertains to the paper-making pulping technique field, especially relates to a Chinese medicine dregs as raw material pulping. The object of the invention is to provide a paper pulp for preparing corrugated paper, wrapper paper and the like, taking the Chinese medicine dregs as raw material through a mechanical physical method pulping method and technique. The method and technique includes: boiling multiform chinese medicine dregs in pressure vessels or normal pressure steamers; pulp milling, pulp washing and pulp mixing in a mechanical method; respectively obtaining fibre pulp and powdery deposited matter. The fibre pulp can be used for preparing various paper products such as corrugated paper or wrapper paper; the deposited matter and paper making water can be used as organic inorganic fertilizer, animal fodder, or the like after a precipitating centrifuge process.

Description

technical field [0001] The invention belongs to the technical field of papermaking and pulping, and in particular relates to pulping with traditional Chinese medicine dregs as raw materials. Background technique [0002] The raw materials that the paper industry relies on are wood pulp, waste paper pulp and non-wood pulp. my country is a country that is extremely short of wood resources. For a long time, my country has followed a development path that uses non-wood fibers such as straw and wheat straw as the main raw materials and small paper mills as the main body. Due to the lack of forest resources in my country, in terms of raw material utilization, the "Eleventh Five-Year Plan" proposed to further reduce the proportion of wood pulp fibers in paper products, so as to reduce wood consumption and improve the utilization rate of waste pulp. [0003] There are more than 1,000 traditional Chinese medicine production enterprises in my country, and the annual production of tra...
