Refractory production line
The refractory production line is 6-16 kinds of raw material batching production line, divided into static and dynamic batching methods, daily only 3-4 people can complete the operation of a single line (including packaging, palletizing), this system includes feeding system, weighing control system, conveying system, mixing system, packaging metering system and central control system.
Each component is introduced
1. Feeding system:
From 6 to 30
The storage bin is composed of a square layout, saving space, and the mouth of the bin is open and closed.
1.1 Open feeding mode
It is equipped with a grille to prevent workers from mistakenly putting impurities such as bags into the bin when feeding. The bottom of the bin is equipped with a material level controller to facilitate real-time monitoring of the use of materials in the bin and ensure continuous production. When a material level device is used in a bin, the material level device is fed back to the central control system through signal, and the system will automatically alarm to prompt manual feeding. At the same time, the operation display displays the corresponding missing material bin, and the corresponding material is lifted to the top of the corresponding bin on the platform by the crane according to the prompt, and then the corresponding material is put into the bin by the manual.
1.2 Closed feeding mode
Use bucket lifts to lift materials
1. Small driving power, the use of inflow feeding, induced discharge, large capacity of hopper intensive layout. When the material is lifted, there is almost no backfeed and digging phenomenon, so the ineffective power is less.
2. Wide range of lifting, this kind of lifting machine on the type of materials, characteristics of less requirements, not only can improve the general powder, small granular materials, but also can enhance the larger grinding material, good sealing, less environmental pollution.
3. Good operation reliability, the most advanced design principle and processing method, to ensure the reliability of the whole machine operation, trouble-free time more than 20,000 hours. High lifting height. The elevator runs smoothly, so it can achieve a high lifting height.
4. Long service life, the feed of the elevator takes the inflow type, the hopper is used to dig, and the extrusion and collision phenomenon rarely occurs between the materials. The machine is designed to ensure that the material is less scattered during feeding and unloading, reducing mechanical wear.
2. Weighing control system:
2.1 Belt weighing (also known as static batching)
We use belt and screw feeding method weighing system is one by one feeding method feeder through the frequency converter to control its speed feeder set high and low speed when the target value is to be reached (generally about 80% of the target value), the frequency converter will speed from fast to low speed. The feeder stops when the target value is reached. The next material starts to mix so as to ensure the speed and accuracy of the entire mix.
2.2 Car weighing (also known as dynamic batching)
The electronic scale of automatic weighing car is an automatic weighing device for continuous feed measurement, and the weighing capacity can reach 10000kg. It overcomes the shortcomings of the gap production of the traditional batching system, and uses PLC control, frequency conversion control and other technologies to effectively solve the contradiction between real-time control and dynamic measurement accuracy. The whole batching process is controlled by PLC. The man-machine interface uses the configuration software of DELL computer and Bozheng *. It can dynamically display the position of the batching car and display the weight of the batching in real time. After each dosing is completed, the actual amount of the dosing is immediately displayed on the screen of the corresponding bin until the next dosing starts to refresh to zero. The amount of ingredients in each bin is retained in the system database, which can be easily invoked for query, comparison and printing, and generate daily and monthly reports. The system records data that the operator cannot modify, delete or move, so that the manager has a full picture of the real situation of each ingredient.
3. Central control system
The control system can basically realize full automation. The operation is simple, fast, and the production process has good confidentiality. The touch screen and PLC are used together, and the dynamic picture is simulated on the display. Monitor and observe the health of the entire system. The system sets the permission password to ensure the confidentiality of the formula. There are two modes on the monitoring screen: automatic and manual. Manual mode is convenient for equipment debugging and maintenance. Multiple formulas can be stored in the system for easy invocation, and parameters such as formula, batch, motor frequency and mixing time can be changed at any time on the screen. The industrial computer can store daily production reports for easy access, statistical analysis and printing at any time.
