Description
Technical field
The present invention relates to a kind of new blade charging system feed liquid flow adjustment of Primary processing shop charging process in production of cigarettes and verification method.
Background technology
Blade charging process belongs to the special procedure of fiber tow production, plays an important role to improving the aesthetic quality of tobacco leaf, igniting and sucking quality and physical property. Tobacco leaf is after this operation is processed, temperature and the water ratio of blade can be adjusted on the one hand further, to meet the requirement of chopping, on the other hand by by technical recipe requirement and usage ratio, feed liquid is applied on blade uniformly, improve the suction taste of tobacco leaf, ensure that reinforced precision and homogeneity are then the important leverages ensureing that this process goal realizes. During blade charging system is produced, adopting liquid-way system as shown in Figure 1, feed liquid is delivered to first jet 61 and the second nozzle 62 of two respectively by feed liquid from feed liquid pond 1 by toothed gear pump 2 as power by two pipelines through parallel connection after strainer 3, under meter 4. First jet 61 controls its break-make by the first switch-valve 71, adjusts its flow by the first variable valve 51; Second nozzle 62 controls its break-make by the 2nd switch-valve 72, adjusts its flow by the 2nd variable valve 52. Due to feed liquid character and the difference applying ratio, the running frequency of the motor 21 of toothed gear pump 2 is different, and corresponding change also can occur feed liquid flow. There is certain proportionlity in running frequency and the feed liquid flow of the motor 21 of toothed gear pump 2; and the running frequency of the motor 21 of toothed gear pump 2; should remaining on a suitable scope, if when electric machine frequency is less, reinforced process variation is big; easily cause reinforced exceeding standard; otherwise, if electric machine frequency is relatively big, feeds in raw material and easily reach peak value; feed liquid does not catch up with, and easily causes shutdown. The two all can cause unstable product quality, and quality product homogeneity is poor, and enterprise's competitiveness of product in market is brought disadvantageous effect. In addition, the blocking that the place such as pipeline, the first variable valve 51, the 2nd variable valve 52, first jet 61 and second nozzle 62 is possible also can cause the instability of feed liquid flow, it is necessary to carries out checking and regulating.
The control objectives of this feed liquid pipeline is exactly according to feed liquid character and the difference applying ratio, by adjusting the running frequency of motor 21, by feed liquid stability of flow near target value. According to Theoretical Calculation and experiment, when first jet 61 and second nozzle 62 are opened simultaneously, if wishing that feed liquid stability of flow is at Q0Time neighbouring, the running frequency of motor 21 should be set as f0. The running frequency keeping motor 21 is f0When constant, if total flux when opening first jet 61 and second nozzle 62 is Q simultaneously0, flow when only opening in first jet 61 and second nozzle 62 is respectively Q1And Q2, then there is following experimental formula Q0��(Q1+Q2) x0.7. Further, if at Q1=Q2When, there is Q0��1.4Q1Relation.
