Viscose fiber is a generic name of viscose fiber, and is also divided into viscose filament and viscose staple fiber. Viscose is cellulose fiber produced by using cotton or other natural fibers as raw materials. The moisture content of the fabric most meets the physiological requirements of human skin, and the fabric has the characteristics of smoothness, coolness, ventilation, static resistance, gorgeous dyeing and the like. In the production of viscose, the feeding is a key process of stock solution viscose preparation, and the function of the feeding is to feed pulp into a pulper, add alkali liquor to prepare the pulp by alkalization, separate particle impurities and hemicellulose in the pulp to generate alkali cellulose, and then the viscose is prepared by subsequent production. The control target needs to be timely and accurately realized in the process, the continuous and stable subsequent production is ensured, and the product quality is ensured to reach the standard.
The existing pulp feeding procedure mostly adopts a semi-automatic process, in order to ensure the stable dipping concentration and yield in the feeding process, the concentration of alkali liquor and pulp needs to be adjusted, the stable process and efficiency of the squeezing procedure are ensured, and the normal operation of equipment is ensured. Generally, a pulper and a pulp storage tank are adopted for batch centralized preparation, the alkali liquor is firstly added, then the pulp is put into the pulper for mixing and blending, and after blending is finished, the pulp is conveyed to the storage tank and then supplied to the next working procedure. In order to improve the automation and the continuity of viscose production and realize the continuous automatic feeding of pulp.
Since continuous feeding requires continuous feeding of pulp and caustic soda into the pulper, problems remain, although some energy consumption may be reduced. For example, in actual production, the speed fluctuation of continuous meal feeding is large, which can cause the concentration of the slurry and the porridge to change, and further influence squeezing; secondly, pulp needs to be erected during continuous pulp feeding, so that the pulp can be peeled by a paging knife, and a large amount of labor is consumed due to low automation in the pulp erecting process; finally, the continuous feeding process has integrity, once a certain link fails, the whole production is affected, and the stability is inferior to that of intermittent feeding. Therefore, in order to improve the stability of pulp feeding, there is still a need to further improve the pulp automatic feeding process, and improve the automation level of the equipment and the stability of the feeding process.
Utility model patents with publication numbers CN203450746U and CN 204280767U both disclose an automatic feeder suitable for pulp feeding, the latter adds a receiving turnover mechanism on the basis of the former, simplifies the process of raising pulp and reduces the labor consumption; secondly, the latter improves the angle of the blades and the number of the blades by designing a novel rotating blade, optimizes the material turning process, and is provided with a gap for the rotating blade to turn upwards between novel material conveying belts for facilitating the material turning, so that the smooth operation of the rotating process is ensured; and finally, after the material level of the material is sensed by the sensing probe, the material pushing mechanism is supported and controlled by the air cylinder to move back and forth and up and down, so that material pushing and feeding are realized, and the automation degree and efficiency are improved. However, the conveying and feeding mode is that the conveying chain conveys a plurality of unpacked pulp sheets at the same time, once the conveying belt fails to stop in time in the conveying process, a large amount of pulp sheets are stacked together, the weight borne by the blades is changed from the previous one into a plurality of bags, the weight is difficult to overcome by the motor, the pulp sheets need to be processed by people, and the processing process is complex.

In the stock solution preparation procedure of viscose fiber production, the stability of the squeezing and ageing processes can be ensured through the stability of the front-end pulp soaking process.
In this example, the squeezing function is to squeeze out the excess alkali solution, remove hemicellulose and impurities, and ensure the stability of the a-cellulose content. In a specific example, the percent of pass of the a-cellulose content of the pressing process was increased from 80% before use to 95% after the pulp automatic feeding process described in example 1 was used, under the same pressing process.
The ageing effect is that the alkali cellulose is kept for a certain time at a constant temperature, and is oxidized and degraded in the air, the polymerization degree is reduced to meet the process requirement, and meanwhile, the narrower the distribution of the polymerization degree, the better the strength of the fiber is. In a specific example, the pulp automatic feeding process described in example 1 is adopted under the premise of the same aging process, and the aging process parameters are as follows: the qualification rate of the polymerization degree can be improved by 10 percent.
Therefore, the stability of the pulp automatic feeding process can ensure that the polymerization degree process is more stable and the polymerization degree distribution is smaller. In a specific example, the strength of the viscose product can be increased from 2.60cN/dex to 2.72cN/dex by using the pulp automatic feeding process described in example 1 compared with the strength of the viscose product before use in a continuous viscose production process.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiments according to the technical spirit of the present invention are included in the scope of the present invention.
