Description of the drawings:

[0008] Figure 1It is a schematic diagram of the structure of the utility model;

[0009] Figure 2 It is a system flow chart of the utility model.

[0010] In the figure: unloading bin 1, weighing scale 2, conveying belt 3, mixing belt 4, unloading hydraulic rod 5, baffle 6, plug hole 7, positioning hole 8, positioning rod 9, V-shaped unloading rack 10, and placement rack 11. Specific implementation method:

[0011] like Figure 1 to Figure 2As shown, an alloy smelting batching system includes a feeding bin 1, a weighing scale 2, a conveying belt 3 and a mixing belt 4. The feeding port of the feeding bin 1 is arranged directly above the weighing scale 2, the output end of the weighing scale 2 is arranged at one end of the conveying belt 3, and the other end of the conveying belt 3 is arranged above one end of the mixing belt 4. The top of the weighing scale 2 is covered with a placing rack 11, and the top of the placing rack 11 is provided with a groove, and the inner wall of the groove is inclined. The system is completely open in terms of data and functional interfaces, and provides a common interface transmission protocol in the industry. The network structure has a routing isolation function, which can facilitate the integration of multiple large and central control systems in the later stage, and realize absolutely uniform mixing in the feeding process. The feeding process of multiple weighing scales 2 realizes "sandwich" uniform mixing from the beginning to the end of the mixing belt 4. When the material is stuck, the weighing scale 2 that is not stuck is automatically paused, and it is automatically started after the stuck material is recovered, so as to realize the maximum uniform mixing after the material is stuck; dynamic adaptive conveying belt 3 speed control. The system will modify the speed of the conveyor belt 3 in proportion to the weight change according to the size of the weight setting change of the weighing scale 2. At the same time, it will automatically correct the feeding speed according to the subsequent weighing achievement rate, improve the accuracy of single batching, and reduce the impact on the furnace condition; the single batching error continues to accumulate. If the total accumulated weight is not cleared, the error will be directly corrected to the set weight at the next batching, realizing real-time dynamic correction of the accumulated error, so that the total error of the raw material ratio is always controlled within a very small error range; when sticking occurs on the weighing scale 2, the system will use the sticky weight as the dynamic tare weight, and the sticky weight will be added to the accumulated error for continuous correction, and the system will track the changes of each sticky material, and reversely correct the dynamic tare weight and accumulated error when the sticky material becomes less, so as to truly realize adaptive dynamic tare control while ensuring the weighing accuracy, without the need for frequent manual intervention in tare; the system will automatically determine whether the feeding and discharging process of the weighing scale 2 is smooth, and will actively issue a voice prompt when the conveyor belt 3 fails to discharge; perfect abnormal self-detection and processing capabilities. When any abnormality occurs in any major driving device or sensor, the system can diagnose itself and give a prompt in the alarm information. At the same time, the system will suspend or shut down some system functions under the premise of ensuring safety. The transition silo is filled with a mixed protection control scheme of material level + feed amount + discharge amount, which can reduce the occurrence of overflow when the material level is abnormal and improve the reliability of the system. Unmanned control of the entire system is achieved. The new batching system can achieve higher batching accuracy, more uniform raw material mixing and higher automation rate, and has a complete and open data and control linkage interface, which provides more convenient conditions for the later integration of large and central control systems. The placement frame 11 is covered on the weighing scale 2. When performing maintenance, the whole can be directly lifted up without moving the weighing scale 2 (the weighing scale 2 generally adopts a floor scale, which occupies a large area). At the same time, the inner wall of the top groove is inclined, so when cleaning the internal accumulated material, it can also be cleaned very conveniently.

[0012] The top of the placing rack 11 is hinged with a V-shaped unloading rack 10, and a unloading hydraulic rod 5 is hinged on one side of the top of the V-shaped unloading rack 10. One end of the unloading hydraulic rod 5 is hinged to the side wall of the top bracket of the placing rack 11. A plurality of jacks 7 are evenly arranged on both sides of the top of the V-shaped unloading rack 10. A plurality of positioning holes 8 are evenly arranged on the inner bottom surface of the V-shaped unloading rack 10, and positioning rods 9 are inserted into two of the positioning holes 8. The top of each positioning rod 9 is fixedly connected with a baffle 6. The baffle 6 is in a triangular shape as a whole. A plurality of bolts are screwed on the top of the baffle 6. Each bolt They are all inserted into the corresponding sockets 7 and screwed therewith, and when weighing is carried out, the discharge hydraulic rod 5 is started. As the discharge hydraulic rod 5 extends, the V-shaped discharge rack 10 is tilted, so that the material can be dumped out smoothly, and according to different ingredients, the baffle 6 is inserted into the corresponding positioning hole 8, so that the whole can meet the use of different counterweights. At the same time, in the subsequent cleaning process, the two baffles 6 and the V-shaped discharge rack 10 can be easily disassembled, which makes the cleaning process very convenient and saves the time of shutdown and maintenance.
