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

[0024] See attached figure 1 : A biological degumming tank, the tank body 1 is provided with a device that can open and close the tank cover 2, and the device is composed of a cylinder 3, a balance ball bar 4 and a clamp 5. Balance club 4 one ends are fixed on the tank cover 2, and the other end is connected with the cylinder 5 that one end is fixed on the tank body 1, and it is supported and fixed by support frame 6, can rotate around the fulcrum of support frame 6. The clamp 5 is provided with an automatic or manual clamp. Bottom in tank body 1 is provided with the shelf 7 that puts hemp cage, and shelf 7 is the circular plate with a hole, and its effect is to shelve hemp cage and prevent that the broken hemp that comes off falls to tank body 1 bottom and blocks nozzle. Below the shelf 7 in the tank body 1 is provided with a temperature regulating device 8, which is a pipeline more than one plate, for the passage of hot liquid or hot steam when heating or the passage of col...

Abstract

The invention provides a biological degumming tank which is characterized in that a tank body is internally provided with a temperature-regulating device, the outer side wall of the tank body is provided with a jacket regulating the temperature of a space in the tank body, the tank body is externally provided with a circulating pipe used for circulating solution in the tank body, the circulating pipe is internally provided with an air nozzle, and the top of a tank cover is provided with an air outlet. The invention lays the foundation 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 to the environment.

Description

Technical field: [0001] The invention relates to a device for degumming hemp fibers, in particular to a biological degumming tank for degumming hemp fibers. Background technique: [0002] Existing methods for degumming such as hemp fibers such as ramie, flax, hemp, jute, and nettle are mainly 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...
