A device and method for automatically controlling the discharge of under-sieve materials

technical field

The invention relates to the technical field of quicklime screening, in particular to a device and a use method for automatically controlling the discharge of under-screen materials.

Background technique

Ultrafine powder can be divided into two categories: crushing method and synthetic method. The pulverization method is to atomize a large volume of melt or micronize the particles (jet milling), and the synthesis method is to form particles through the process of nucleation and growth of atoms or molecules. The main method of fine powder, but its productivity is low and the cost is high.

As shown in Figure 5, for the transportation of ultrafine powder, after the existing quicklime is sieved, the massive lime material falls into the vibrating feeder through the crushing hopper under the sieve, and then is distributed to the belts of the two systems through the feeding pipe. For conveying, the first feeding pipe and the second feeding pipe are switched and controlled by the flap valve. Among them, the first conveying system is conveyed through the belt electronic scale, and the second conveying system is directly conveyed by the conveying belt, but due to the first The belt electronic scale process for the production and feeding of the first conveying system is designed for electronic scales. The belt electronic scale runs at a slow speed, so the feeding speed should not be too fast. Too fast will cause material overflow or blockage. The conveyor belt of the second conveying system runs at a fast speed. , so the feeding amount should be large. The vibrating feeder has only one amplitude during operation. If it can satisfy the belt electronic scale of the first conveying system, it cannot satisfy the conveying belt of the second conveying system. Each feeding must be done manually. Switching and adjusting the vibration pair of the vibrating feeder will bring inconvenience to production, low production efficiency, and increased labor costs. This problem needs to be solved urgently.
