Description

Technical Field

[0001] The utility model relates to an automatic processing device for hemp raw materials, which is used for improving the cleanliness of the hemp raw materials and belongs to the technical field of non-wood fiber processing. Background Art

[0002] As one of humanity's earliest textile raw materials, hemp fiber has a long history. In recent years, with the advancement of technology and increased environmental awareness, the application of hemp fiber has gradually expanded towards new materials, greening, cleanliness, efficiency, and sustainable development.

[0003] The multi-purpose utilization of hemp fiber is a current research hotspot. Hemp crops are not only widely used in the textile industry but also demonstrate significant value in biopharmaceuticals, ecological restoration, and papermaking. Hemp fiber holds broad market potential in industrial specialty papers, tobacco, banknote paper, high-end household paper, and the specialty cellulose industry. Hemp fiber is a natural fiber with high strength and good hygroscopicity. In papermaking applications, hemp fiber provides the mechanical strength and electrical properties required for paper, making it a valuable asset in the manufacture of electrolytic capacitor paper, among other applications.

[0004] At present, hemp long fiber raw materials contain too many foreign cells and pectin. During the pulping process, the subsequent pulping process will increase the amount of chemicals used, and it will also cause great trouble to the wastewater discharge load. The high content of foreign cells will increase the amount of washing water, reduce the washing capacity, and lead to low black liquor concentration and low pulp cleanliness. The presence of pectin will reduce the filterability and formability of the pulp, increase the viscosity of the pulp, and thus affect the washing and bleaching process of the pulp. The removal of these non-cellulose substances not only increases the complexity of the process, but also increases the difficulty of wastewater treatment. Hemp degumming can be divided into chemical degumming and biological degumming methods. Although the chemical degumming method has been industrialized, it pollutes the environment more. The biological degumming technology removes pectin and hemicellulose by using biological agents, but it requires a longer cycle.

[0005] Currently, the mechanized processing of hemp fiber is still in its developmental stages. Domestic hemp fiber production processes are still very backward, largely manual, with low automation, high labor input, and high processing costs. The resulting product is of low quality, confining it to the low-end market.

[0006] In view of the disadvantages of the above treatment methods, it is necessary to design a device that relies on mechanical force to treat hemp fibers to purify the hemp fibers, remove pectin and other substances that are not conducive to subsequent processes, obtain relatively pure hemp fibers, and improve the utilization efficiency of hemp fibers, reduce environmental pollution, and improve product quality. Summary of the Invention

[0007] The problem to be solved by the utility model is to provide a device for effectively cleaning long-fiber hemp raw materials.

[0008] In order to solve the above problems, the technical solution of the utility model is to provide an automated processing device for hemp raw materials, which includes a cleaning tank cylinder, the cleaning tank cylinder is provided with a feed port and a discharge port, and a feed spray pipe is provided on the top of the feed port; two groups of knife fling groups are provided in the cleaning tank cylinder, and a hump spray pipe is provided above the two groups of knife fling groups. Each group of knife fling groups includes mutually nested core shafts and blades arranged on a sleeve. The two ends of the core shaft are movably connected to a pair of shaft wheels fixed in the cleaning tank cylinder, and one end of the core shaft is connected to the motor.

[0009] Preferably, an observation manhole is provided on the top of the cleaning tank cylinder.

[0010] Preferably, an overflow sewage discharge device is provided on one side of the cleaning tank barrel.

[0011] Preferably, the bottom of the overflow sewage discharge device is connected to the cleaning tank cylinder through a cleaning tank discharge pipe.

[0012] Preferably, a liquid level gauge is provided in the cleaning tank cylinder.

[0013] Preferably, a plurality of groups of blades are distributed on the sleeve of the blade-flinging group along the axis, the number of blades in each group is 7-10, and the interval between two adjacent groups of blades is 150 mm.

[0014] Preferably, a cleaning tank discharge pipe is provided at the bottom of the cleaning tank cylinder.

[0015] Preferably, a flow guide bend is provided between the two groups of blade-flinging groups.

[0016] The utility model can effectively solve the cleaning problem of long-fiber hemp raw materials, improve the quality and production efficiency of hemp fibers, and has good market application prospects.

[0017] This new automatic hemp processing device utilizes a production line control system for full automatic control of the entire process. This control, combined with the feed belt in the previous stage, allows for further precise control of the processing concentration. The hemp beating machine utilizes a variable-frequency motor to control the beating speed, and the two sets of flingers can be set to different speeds. High-frequency vibrations generated by the high-speed rotating flexible impeller striking the water surface clean the hemp fiber surface, resulting in relatively pure hemp fibers.
