[0002] As we all know, bamboo is a perennial herbaceous plant of the Poaceae family, originating in China. Fresh bamboo contains more than 50% water, 20%→25% cellulose, 15%→20% hemicellulose and 10%→15% lignin (varies with species). At present, people's development and utilization of bamboo is relatively extensive, mainly concentrated in the three major application areas of pulping and papermaking, broken bamboo weaving and smoldering carbon making. The output variety is single, the resource utilization rate is low, the technical content is not high, and the economic benefits are low. Especially in the pulping and papermaking industry, the application of chemical agents such as acids and alkalis is indispensable, which not only consumes a lot of fresh water resources, but also discharges a large amount of chemical wastewater to pollute the ecological environment. Therefore, it is very necessary for us to provide a bamboo raw material co-production production line through innovative research and development, promote the iterative upgrading of my country's bamboo industry technology, and improve the environmental protection technology level and economic benefits of the bamboo processing industry. Summary of the invention

The PLC console has an appearance of a chair-shaped counter, and a signal display system, a PLC operation control system, a power supply system and a signal transmission line connecting the controlled equipment are respectively arranged in the cabinet and inside. The gas distribution station has an appearance of a Y-shaped tube, which is composed of a main pipe and a branch pipe arranged at an angle. The slurry pool has an appearance of a boat-shaped pool, and at least one round and long vibrating rod that can be raised and lowered is arranged above the pool edge, a round slurry pump is arranged in the pool, a long strip groove is arranged at the bottom of the pool, and a lignin recovery device is arranged in the groove. The screw extruder has an appearance of a long strip frame, which is assembled from a slurry pump, a frame and a screw propulsion device. The slicer, cooking tank, high-concentration grinder, screw extruder, fermentation container, distillation device and liquid storage tank are all fairly mature special equipment in the papermaking machinery and liquor machinery industry. They are selected according to production process parameters and flexibly assembled as special machines for use in this joint production line.

[0005] The beneficial effects of the utility model are as follows: first, the main production equipment on the production line is centrally controlled through the PLC console, realizing the automated production scheduling of the entire production line; second, on the same production line, multiple bamboo raw materials can be produced successively, thereby improving the utilization value, production efficiency and comprehensive economic benefits of bamboo resources; third, the purchase of mature special machines in the market is added to the construction of the production line, which greatly saves the construction cost and time of the production line.
