The applicant finds that mechanical dynamics analysis and parameter optimization are needed to be carried out on the feeding process of the high-frequency vibration groove, the correlation between the high-frequency vibration groove parameters and the moisture standard deviation of the tobacco shreds at the outlet is found out, the transmission performance of the tobacco shreds is improved, and meanwhile, the fatigue fracture of the spring plate fixing bolt or the spring plate is reduced.
Fig. 1 is a schematic flow diagram of some embodiments of a vibration groove parameter configuration method of the present disclosure.
In step 110, a correlation between standard deviation of moisture of the cut tobacco at the outlet and the throwing index is obtained.
The throwing index is related to the frequency of a vibration exciter frequency converter of the high-frequency vibration groove and the vibration amplitude of the vibration groove. The vibration amplitude of the vibration groove is adjusted by the frequency of a vibration exciter frequency converter and the contact ratio of the eccentric block, so that the throwing index is greatly influenced by the frequency of the vibration exciter frequency converter and the contact ratio of the eccentric block.
In some embodiments, the correlation between standard deviation of cut tobacco moisture and throw index is found by multiple sets of experiments. For example, the standard deviation SD value of the moisture of the cut tobacco at the outlet, the amplitude of a high-frequency vibration groove, the contact ratio of an eccentric block and the throwing index D in a preset time are collected through a data collection system and are subjected to statistical analysis, wherein the standard deviation SD value of the moisture of the cut tobacco at the outlet can be obtained through online detection of a moisture meter. As shown in Table 1, the 1 month parameter data was retrieved and averaged.
TABLE 1
Then, the correlation between standard deviation SD of cut tobacco moisture and throw index D is obtained according to table 1 and is shown in fig. 2.
In step 120, the throwing index corresponding to the feasible range of the standard deviation of the moisture of the export cut tobacco is determined according to the correlation.
In the practical concrete engineering, the feasible range of standard deviation SD of the moisture of the cut tobacco at the outlet is 0.230-0.250, and the corresponding throwing index D range is 2.9-3.6. In some embodiments, the throw index D may take on the values 2.9, 2.95, 3.0, 3.05, 3.1, 3.15, 3.2, 3.25, 3.3, 3.35, 3.4, 3.45, 3.5, 3.55, 3.6, and so forth.
At step 130, the parameters of the vibratory tank are configured according to the corresponding throw index based on the throw index theoretical formula. The vibration groove parameters comprise the frequency of a vibration exciter frequency converter of the vibration groove and the contact ratio of the eccentric block.
The theoretical formula of the throwing index is as follows: d ═ λ w2sinδ)/(gcosα0) Where w is 2 π n/60 and n is 60 xf/p, resulting in D4 λ π2f2sinδ/p2gcosα0. Wherein D is a throwing index, lambda is vibration groove amplitude, f is vibration exciter frequency converter frequency, delta is vibration direction angle, p is motor pole number, g is gravity acceleration, alpha0Is the inclination angle of the vibration groove. Angle delta in vibration direction and inclination angle alpha of vibration groove0When the number p of the motor stages is determined, the throwing index D is only related to the vibration groove amplitude lambda and the frequency f of a vibration exciter frequency converter, namely D is k lambda f2. And the vibration amplitude lambda of the vibration groove is related to the frequency f of the vibration exciter frequency converter and the contact ratio of the eccentric block. As shown in figure 2, the contact ratio of the eccentric blocks of the vibration exciter is adjusted by adjusting the included angle of the two eccentric blocks.
Therefore, in some embodiments, a vibration direction angle parameter, a vibration groove inclination angle parameter and a pole number parameter of a frequency converter motor of the vibration groove are obtained; determining a throwing index according to a throwing index theoretical formula, and determining a corresponding relation between the throwing index and the frequency of a vibration exciter frequency converter and the vibration groove amplitude; by adjusting the frequency of the vibration exciter frequency converter of the vibration groove and the contact ratio of the eccentric block, the adjusted frequency of the vibration exciter frequency converter, the vibration groove amplitude and the throwing index satisfy the corresponding relationship.
In the embodiment, the throwing index corresponding to the feasible range of the standard deviation of the moisture of the outlet cut tobacco is found, and then the vibration tank parameters are configured, so that the vibration tank parameters are quickly and accurately optimized and matched, the relative motion of the cut tobacco and the tank body is perfected, and the purposes of reducing the standard deviation of the moisture of the outlet cut tobacco and reducing the frequency of high-frequency vibration tank faults are achieved.
Fig. 4 is a schematic flow chart of another embodiment of a vibration groove parameter configuration method according to the present disclosure.
At step 410, a correlation between standard deviation of moisture in the cut tobacco at the outlet and the throwing index is obtained.
In step 420, the throwing index corresponding to the feasible range of the standard deviation of the moisture of the export cut tobacco is determined according to the correlation.
In step 430, according to the vibration energy efficiency of the vibration conveyor, the throwing index corresponding to the feasible range of the standard deviation of the moisture of the cut tobacco at the outlet is optimized to obtain the optimized throwing index.
Corresponding to the vibration conveyor, when D is 1-3.3, the vibration groove only has one throwing motion when vibrating once; when D is more than 3.3, the vibration groove vibrates for a plurality of times, and the material only has one throwing motion. Therefore, D is 1-3.3 to reduce energy consumption and improve efficiency. And then, referring to the throwing index corresponding to the feasible range of the standard deviation of the moisture of the export tobacco shreds, wherein the range of the optimized throwing index is 2.9-3.3.
In some embodiments, the optimized throw index may take on a value of 2.9, 2.92, 2.94, 2.96, 2.98, 3.0, 3.02, 3.04, 3.06, 3.08, 3.1, 3.12, 3.14, 3.16, 3.18, 3.2, 3.22, 3.24, 3.26, 3.28, 3.3, etc.
The range of the throwing index is limited to be 2.9-3.3, the phenomenon that the vibration groove vibrates for many times and the material is thrown for one time is prevented, low-frequency low-amplitude downward exploration of the high-frequency vibration groove is realized, the fatigue fracture times of the spring plate and the fixing bolt are greatly reduced, the damage degree of vibration groove parts is reduced, and the vibration groove parts almost reach a maintenance-free state.
In step 440, a vibration direction angle parameter, a vibration groove inclination angle parameter and a pole number parameter of the frequency converter motor of the vibration groove are obtained.
In step 450, based on the throw index theoretical formula, the throw index is determined, and the corresponding relation between the frequency of the vibration exciter frequency converter and the vibration groove amplitude is determined.
In some embodiments, the throwing index is related to the frequency of the vibration exciter converter and the vibration groove amplitude by D ═ k λ f2If the parameters of a certain device are shown in table 2, that is, the vibration direction angle of the vibration groove is 25 °, the inclination angle of the vibration groove is 0 °, and the number of poles of the motor is 2, k is 0.426. Those skilled in the art will appreciate that the value of k can be derived from actual parameters of the device.
In step 460, the frequency of the vibration exciter frequency converter of the vibration tank and the contact ratio of the eccentric block are adjusted, so that the adjusted frequency of the vibration exciter frequency converter, the amplitude of the vibration tank and the throwing index satisfy a corresponding relationship.
Because the optimized throwing index is determined, namely the value range of the throwing index is reduced, the frequency of a vibration exciter frequency converter of the vibration tank and the adjustment frequency of the contact ratio of the eccentric block can be reduced, and the ratio between the frequency converter and the eccentric block can be found out more efficiently. For example, in the related art, as shown in fig. 4, when the contact ratio of the eccentric block is adjusted, the adjustment is performed within a range from 30 ° to 120 °, and after the optimized throwing index is obtained, the contact ratio of the eccentric block is adjusted within a range from 60 ° to 90 °, so that the correspondence relationship between the frequency of the vibration exciter transducer and the vibration groove amplitude and the throwing index is satisfied, and the adjustment efficiency is improved.
In addition, the larger the throwing index is, the stronger the loosening capacity and the balancing capacity of the vibration tank on the materials are. However, if the throwing index is too large, the fatigue life of the vibrating trough structure is reduced. Therefore, the method researches the value of the throwing index under the condition of meeting the loose property requirement, explores the relation between the high-frequency vibration tank parameter and the tobacco shred motion characteristic, performs correlation analysis on the throwing index and the standard deviation value of the water of the tobacco shreds at the outlet, and has good guiding significance and wide popularization and application for optimizing the proportioning of the high-frequency vibration tank parameter before the airflow tobacco dryer by determining that the optimal range of the throwing index is 2.9-3.3. The relevance measurement method for the multiple parameters of the high-frequency vibration groove in the test process can provide reference for improving the performance of the high-frequency vibration groove in the tobacco industry.

In the practical concrete engineering, the feasible range of standard deviation SD of the moisture of the cut tobacco at the outlet is 0.230-0.250, and the corresponding throwing index D range is 2.9-3.6.
In other embodiments, the throwing index determining unit 520 is further configured to optimize the throwing index corresponding to the feasible range of the standard deviation of the moisture of the cut tobacco at the outlet according to the vibration energy efficiency of the vibration conveyor, so as to obtain the optimized throwing index.
Corresponding to the vibration conveyor, when D is 1-3.3, the vibration groove only has one throwing motion when vibrating once; when D is more than 3.3, the vibration groove vibrates for a plurality of times, and the material only has one throwing motion. Therefore, D is 1-3.3 to reduce energy consumption and improve efficiency. And then, referring to the throwing index corresponding to the feasible range of the standard deviation of the moisture of the export tobacco shreds, wherein the range of the optimized throwing index is 2.9-3.3.
The larger the throwing index is, the stronger the loosening capacity and the balancing capacity of the vibration tank on the materials are. However, if the throwing index is too large, the fatigue life of the vibrating trough structure is reduced. Therefore, the throwing index value under the condition of meeting the requirement of looseness realizes low-frequency low-amplitude downward detection of the high-frequency vibration groove, and the fatigue fracture times of the spring plate and the fixing bolt are greatly reduced.
The vibration tank parameter configuration unit 530 is configured to configure a vibration tank parameter according to a corresponding throw index based on a throw index theoretical formula.
Angle in vibration directionUnder the condition of determining the inclination angle of the vibration groove and the motor stage number, the throwing index is only related to the vibration groove amplitude and the frequency of a vibration exciter frequency converter, namely D is k lambda f2. The vibration amplitude of the vibration groove is related to the frequency of the frequency converter of the vibration exciter and the contact ratio of the eccentric block.
