Problems solved by technology

In long-term use, it is very clear that there are many shortcomings in the chemical degumming method: 1. The quality of the fiber is greatly damaged, because the tissue of the fiber is damaged after being treated with acid, alkali and high temperature and high pressure; 2. The cost High, high energy consumption, because it needs to consume a lot of acid and alkali and electricity, and the acid and alkali used cannot be recycled, so that the cost is high; 3. The equipment is easy to corrode and has a short life; 4. Serious environmental pollution
Due to the different media and conditions required for biological degumming and chemical degumming, chemical degumming tanks are no longer suitable for biological degumming

Embodiment Construction

[0018] See attached figure 1 , the structure and production process of this device are:

[0019] One, the steam in the steam generator 1 is introduced into the seed tank 2 (the quantity of the seed tank 2 is determined according to the production scale, which is more than one.), the seed tank 2 is subjected to high-temperature sterilization, and after sterilization, it is lowered to a suitable temperature. Place the basophilic bacillus in it, adjust the dissolved oxygen, temperature and other parameters, and prepare it into a bacterial liquid whose solubility and other parameters meet the requirements. During the fermentation process, when the temperature in the seed tank 2 is higher than the set value, the system automatically opens the cold water solenoid valve to cool down; when the temperature in the tank is lower than the set value, the system automatically turns on the hot water circulation pump. The operation modes of the stirring motor in the seed tank include manual ...

Abstract

The invention provides a bast-fibre biological degumming device which is characterized by comprising a seed tank, a biological degumming tank, a steam generating device, an air device and a chemical degumming tank, all the tanks are connected with the devices through pipes with controllers, and the controllers are electrically connected with a programmable controller. The invention develops the direction for the industrialization and the scale of bast-fibre biological degumming, lowers the production cost, improves the quality and the yield of bast-fibre, and greatly lightens the pollution tothe environment.

Description

Technical field: [0001] The invention relates to a device for degumming hemp fibers, in particular to a biological degumming device for hemp. Background technique [0002] Existing hemp fibers, such as the methods of degumming such as ramie, flax, hemp, jute, nettle, mainly are chemical methods. They first pickle the hemp with acid, and then boil it with lye under high temperature and pressure to hydrolyze the pectin, lignin and semi-lignin in the hemp and remove it by washing, and then make it spinnable after post-processing. dry hemp. The device used in the chemical degumming method is mainly a chemical degumming tank, which is composed of a pressure-resistant tank body. The tank body is provided with inlets, outlets and steam inlets for heating. The lower part of the tank body is provided with a shelf for placing hemp cages. . In long-term use, it is very clear that there are many shortcomings in the chemical degumming method: 1. The quality of the fiber is greatly dam...
