Description
Technical Field
The invention relates to the technical field of manganese-zinc ferrite magnetic material production, in particular to a production system for realizing automatic pelletizing of manganese-zinc ferrite.
Background
At present, two production and manufacturing processes of manganese zinc ferrite are available, namely wet process manufacturing and dry process manufacturing, and along with intensification of production cost, the dry process is the most widely applied production process at present. However, the limitation is that the flexibility of material switching, the accuracy of the formula and the like are poor, and the full-automatic and intelligent degree of the dry process is lagged. Compared with the wet method, the method just makes up the defect of the dry method, and has the advantages of stronger automation degree of the wet method, higher purity of the obtained finished product and better stability. However, the disadvantages of the wet process are obvious, namely the high production cost and the long process flow. From the standpoint of cost and efficiency, the dry process is more suitable for mass production and is better than wet manufacturing in terms of physical molding properties.
As shown in fig. 1, a production system of a conventional dry process for producing and manufacturing manganese zinc ferrite comprises four bins, namely an iron oxide bin I1, an iron oxide bin II 2, a manganese oxide bin 3 and a zinc oxide bin 4. The lower part of each bin is provided with a screw feeding device 5, a weighing hopper I6 is arranged under each screw feeding device 5, a screw feeding device 5 is arranged under each weighing hopper I6, the screw feeding devices 5 under all weighing hoppers I6 are summarized into a weighing hopper II 11, a mixing device 18 is arranged under each weighing hopper II 11, the mixed materials enter a vibration mill 19 and then enter a subsequent bin 20 through the screw feeding device 5 at the lower part, three artificial pelletizers 21 are provided, each pelletizer is provided with a bin 20, the materials from the vibration mill enter the bin 20, the lower part of each bin 20 is provided with a screw feeding device 5, the materials are fed into each artificial pelletizer 21, and then an appropriate amount of water is added to cause required balls for subsequent pre-sintering.

1. raw and other materials weigh the process loaded down with trivial details, and every feed bin has set up the weighing hopper, although has improved the precision of weighing to a certain extent, but influences the continuity of mass production, and in actual operation in-process, the characteristic of raw and other materials leads to the raw and other materials in the weighing hopper often not to be empty, leads to the unloading valve of weighing hopper often to close the delay, and the production in-process often needs the weighing hopper to peel, just can make the valve close, follow-up continuous operation. Not only does not improve the weighing precision, but also the workload of staff is increased to a certain extent.
2. The mixed raw materials are subjected to vibration grinding, the steps are complicated, and if the mixing and vibration grinding processes can be replaced by one device, the mixed raw materials have higher loose ratio, so that the processes are simpler. The fewer steps, the less degree of continuity is caused by equipment failure. The higher the production efficiency will be
3. The vibration-ground mixed material does not realize automatic material mixing, but the lifting hopper sends the material to each pelleting bin, the nearest bin is sent first, then the second bin is sent to the third bin in sequence, in the operation process, the farthest third pelleting machine does not pelletize the material, the pelleting quantity of each pelleting machine is limited, the problem of uneven material feeding is solved, and the pelleting efficiency is greatly reduced.
