Design And Application Of Factory Automatic Weighing And Oil Distribution System Based On PLC

Chemical enterprises are involved in the process of adding various formula raw materials.A variety of raw materials are added to the mixing equipment in a certain proportion,and the required products are produced through the designed process and processingweighing and Automatic batching system that widely used in chemical industry,It’s generally in the first process,plays an important role.But the automatic batching system is based on solid or powder raw materials as processing object,The solid material delivery and weighing form are not applicable when raw material is liquid,Because the liquid raw materials on the mode of transportation and weighing way with solid particles and powder raw material is very different,It is difficult to directly use the system in the liquid raw materials condition.Now the traditional liquid batching methods include constant volume filling method,such as the car refueling system,liquid beverage filling,etc.The advantages of constant volume filling are high efficiency,but the disadvantage is that it does not calculate the residual amount in the container,the actual amount of filling is generally small,and the deviation can not be corrected,resulting in uncontrollable product quality.Another common method of liquid filling is manual weighing and compounding.For some liquid raw materials with less amount,the filling process is generally completed manually.The main process is as follows: filling liquid into measuring cup for weighing,manually transporting to the platform scale for weighing the total weight,and manually feeding.This process is inefficient,the labor intensity of employees is high,the weighing accuracy cannot be guaranteed,the pollution source in transportation cannot be controlled,and the quality cannot be guaranteed.This method can no longer meet the requirements of modern factories for production efficiency and quality.This paper firstly analyzes and studies the production process of adding process oil in existing chemical production.Summarizes and constructs the flow chart of adding process oil in production.Basedon the production process flow chart analysis and summary of the mainstream automatic oil adding equipment weighing advantages and disadvantages.After analyzing the advantages and disadvantages of the existing automatic oil weighing method,This paper designs the system by combining the advantages of the existing equipment weighing method,and deduces a set of automatic weighing and oil distribution system by combining various weighing methods.In order to meet the needs of chemical enterprises,it is necessary to develop a set of automatic weighing and oil distribution system.In this paper,according to the actual production needs,a set of automatic weighing and oil distribution system is designed to improve the manual weighing and oil distribution in the process of various problems.The system includes oil tank device,a set of pipeline device,valve and control device,a set of weighing measurement device.The process flow is as follows: the oil is transported to the machine position by the oil pipeline in the storage tank,and the oil is added to the metering and weighing device by the valve control system.After completing the metering and technological configuration,the oil is discharged to the processing device in the next process through the oil discharge pipeline.This system has been put into the factory actual mass production of product processing.he system meets the design objectives and factory requirements.Working process in accordance with the actual production process step,automatic weighing quality error tested and adjusted within the error range,oil distribution was improved the production efficiency and quality and production environment improved,while reducing the labor intensity of workers,bring direct benefits to factory,It has complete installation in 10 production lines,Saving the wasted and labor costs more than 100,000 RMB each year.
