Development Of Feeding System For Firebrick Double Electromagnetic Vibrating Feeder

Refractory brick feeding system can not only influence the production efficiency of refractory brick,but also determine the quality of refractory brick by the accuracy of its batching.However,in the traditional firebrick production,the main production method is manual weighing.Although this production method is simple,both the accuracy and efficiency of the measurement are poor.This is not conducive to automatic mass production of firebrick,and the performance of the produced firebrick can also not be effectively guaranteed.As a modern material conveying machinery,electromagnetic vibrating feeder has the characteristics of low noise,no pollution,environmental protection,etc..It has been widely used in the production process of powder and particle feeding materials in industrial industries.However,the production site of firebrick is of dusty,with high labor intensity and low work efficiency.This does great harm to the workers’ health under such an environment for a long time.With the improvement of enterprises’ requirements for the efficiency and precision of products,the traditional single electromagnetic vibration feeding system is difficult to meet them.Therefore,both the influence and control of feeding parameters of refractory brick dual electromagnetic vibration feeder are studied in this paper.And this equipment can be easily controlled by the remote terminal in order to improve the feeding efficiency and accuracy of the electromagnetic vibration feeder.The system is the core part of the whole automatic firebrick production.Firstly,the feeding dynamics and electromagnetic vibration mechanics models of double electromagnetic vibration feeder are created,respectively.And the influence of feeding parameters are calculated and analyzed.Then,according to the theoretical analysis results and fire brick production process needs,the dual electromagnetic vibrating feeder feeding system structure is designed.And the internet control system of equipment is established,which regards the PLC as the core,uses the remote industrial Internet of things,and the realizes its terminal control through the PLC communication connection.Finally,an orthogonal experiment is carried out on the prototype,and the optimal working parameters and reasonable optimization parameters of the feed tank structure are obtained according to the analysis of experimental data.Compared with the traditional feeding system,the developed system has the characteristics of high efficiency,precision,terminal remote control function.Its final conveying error can be controlled within ±10g after optimized design relative to the conveying error of the single electromagnetic vibration feeding system(±30g).
