Biological Degumming Water Bath Continuous Fermentation Process And Equipment And Promotion

It is the team leader and head of technology.

Based on the research and application of ramie degumming technology, the project innovating on the traditional ramie degumming process, relying on the original chemical degumming equipment and facilities, increases the oxygen supply and the recharge cost only when the fermentation is used, and uses the new process of inoculating and fermenting the raw linen in the original acid pond to increase the loading capacity of the linen cage. After the cage is used, the bacteria are inactivated by boiling wastewater. The comprehensive water saving is over 50%, the energy saving is over 30%, the chemical material is reduced by more than 60%, the pollutant production is reduced by more than 50%, the cost of degumming is reduced, and the yield and quality of the refined hemp are improved.

Sewage discharge reaches the first level requirement of the national comprehensive discharge standard for sewage.

Main innovation points of the project

1. the innovative process is to mix the bacteria 0.2m3 into the fermenting pot and mix it with the 32 ~33 centigrade warm water in the fermentation pot, add carbon source and helium source, and continue to fill the compressed air. Then the original cage of the cage is hoisted into the fermented pot and then fermented in water bath.

2. new development

A continuous fermentation cage suitable for biological degumming and continuous fermentation of hemp fiber was developed. The fermentation cage increased by 300mm compared with the common hemp cage, and increased from 1800mm to 2100mm. The hemp loading capacity of the linen cage reached 630kg, which was 66% higher than that of the greenhouse fermentation, and the tightness of the linen was ensured.

The project has been successively in Hunan Star Ma industry Limited by Share Ltd, Yuanjiang Si Xin hemp textile Co., Ltd., Yiyang Hui Yuan Textile Co., Ltd. and Hanshou Xinda.

Ltd. and Jiangxi well bamboo Biotechnology Co., Ltd. has been widely applied.

Over the past 3 years, 36429 tons of ramie refined hemp have been produced, and the industrialization of ramie fiber biological degumming technology has been realized. The new output value is 546 million 440 thousand yuan and the profits tax is 63 million 679 thousand yuan, and remarkable economic benefits have been achieved.

Song Yuxia has been engaged in the research of wide and heavy rapier looms for many years.

It is responsible for the electrical design of the project, which is responsible for the development of the electrical control system and guide the manufacture, installation and commissioning of the equipment.

The CXWJ1280 rapier forming net loom has a width of 12.8 meters. It can be used to weave the top grade multi-layer forming net with polyester monofilament as well as other polyester nets and industrial nets. The width and quality of the looms can fully meet the needs of wide and high-speed paper machines and replace imports.

The machine integrates the technology of machine, electricity, gas, liquid and light, has high technical content, and has independent innovation. It solves the problem of weft insertion and opening of super wide loom, and solves the problem of weft insertion and reed weft interference caused by ultra wide width. It has a high cost performance ratio.

The equipment has made breakthroughs in electrical control, which has greatly improved the efficiency and performance of the equipment.

Main innovation points of the project

1. using servo motor to solve the problem of weft insertion of super wide rapier, the servo motor with high resolution feedback encoder is used to directly drive the pmission wheel with circumference of 1m, and a complete weft insertion is achieved.

2. the active opening multi arm (multiple arm) controlled by the cylinder is used to solve the problem of ultra wide opening.

3., by improving the main motor, the contradiction between the belt operation and the reed beating up of the super wide loom can be solved.

The CXWJ1280 rapier loom has sold 21 units from 2012 to March 2014.

Sales revenue of about 78 million yuan, the profit of about 37000000 yuan.

The main customers are: Anhui Ya Dong Jinlong net Industry Co., Ltd., Anhui Huafeng net Industry Co., Ltd. and other more than 10 enterprises.

The user can reflect the success of weaving the finished product net which meets the requirements of the company, and has remarkable economic and social benefits.
