Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0040] The present utility model provides an automatic batching and mixing device for ferrosilicon manganese alloy through improvement. The technical solution of the present utility model is:

[0041] As Figures 1 - 5As shown, the automatic batching and mixing device for ferrosilicon manganese alloy includes:

[0042] A tank body 1, a gantry 2 is arranged at the top of the tank body 1, a rotating shaft 3 is rotatably arranged at the bottom of the gantry 2, and the rotating shaft 3 is rotatably arranged on the inner wall of the bottom of the tank body 1;

[0043] A rectangular hole is opened on the rotating shaft 3, and a connecting frame 4 is slidably arranged in the rectangular hole;

[0044] Two storage components are arranged at the two ends of the connecting frame 4, and the two storage components are respectively used for temporarily storing ferrosilicon manganese alloy raw materials;

[0045] A weighing component is connected to the storage component, and the weighing component is slidably connected to the gantry 2. The weighing component is used to detect the weight of the materials in the two storage components;

[0046] A stirring component is fixed to the rotating shaft 3, and the stirring component is used to mix ferrosilicon manganese alloy raw materials.

[0047] By using the weighing component to detect the quality of the storage component, the weight detection of manganese ore and silica is realized, and thus the ratio of ferrosilicon manganese alloy raw materials is realized;

[0048] During the rotation of the rotating shaft 3, the discharging component is driven to rotate in the tank body 1 through the connecting frame 4. When the storage component outputs materials, the materials can be evenly dispersed at the bottom of the tank body 1, so as to realize the preliminary mixing of the materials. Furthermore, while ensuring the mixing effect of the materials, the time required for the mixing work is reduced, so as to improve the work efficiency.

[0049] Furthermore, the storage component includes:

[0050] A weighing tank 5, the weighing tank 5 is fixed to the end of the connecting frame 4, and both the top and bottom of the weighing tank 5 are open structures;

[0051] A fixing plate 16 is fixed on the inner wall of the weighing tank 5;

[0052] An electric push rod 17 is fixed to the bottom of the fixing plate 16;

[0053] A rod body 18 is fixed to the telescopic end of the electric push rod 17;

[0054] A plug 19 is fixed to the bottom end of the rod body 18, the top of the plug 19 is a conical structure, and the plug 19 is used to block the bottom opening of the weighing tank 5;

[0055] A feed pipe 9 is fixedly penetrated on the tank body 1, and a valve 11 is arranged at the end of the feed pipe 9;

[0056] The hose 12 is connected to the valve 11, and the end of the hose 12 is located inside the weighing tank 5.

[0057] Turn on the switch of the electric push rod 17. When the electric push rod 17 works, the plug 19 is lowered through the rod body 18, so that the bottom opening of the weighing tank 5 is opened, and thus the manganese ore or silica in the weighing tank 5 can fall into the bottom of the tank body 1;

[0058] Through the valve 11, the supply of manganese ore or silica can be immediately cut off to ensure the accurate feeding of manganese ore or silica;

[0059] The manganese ore or silica can be guided into the weighing tank 5 through the hose 12, and when the weighing tank 5 rotates, through the deformation of the hose 12, the rotation of the weighing tank 5 is prevented from being blocked.

[0060] Furthermore, the weighing assembly includes:

[0061] The connecting rod 14 is rotatably arranged at the top of the connecting frame 4, and the connecting rod 14 sequentially penetrates through the top of the rotating shaft 3 and the top of the portal frame 2;

[0062] A plurality of sliding grooves 15 are all formed on the connecting rod 14. A plurality of convex blocks are arranged on the portal frame 2, and the plurality of convex blocks and the plurality of sliding grooves 15 are slidably connected one by one;

[0063] The connecting plate 6 is arranged at the top of the connecting rod 14, and a spring 7 is fixed to the bottom of the connecting plate 6;

[0064] The force sensor 8 is fixed to the top of the portal frame 2, and the force sensor 8 is fixed to the spring 7;

[0065] The controller is electrically connected to the force sensor 8 through a signal line.

[0066] Through the convex blocks and the sliding grooves 15, the connecting rod 14 can only move up and down and cannot rotate, so as to ensure that the external influence on the force sensor 8 is small and the weighing accuracy is ensured.

[0067] Furthermore, the stirring assembly includes:

[0068] A plurality of stirring rods 13 are equidistantly fixed on the rotating shaft 3, and the plurality of stirring rods 13 are all located inside the tank body 1, and each stirring rod 13 is located below the weighing tank 5.

[0069] Furthermore, the stirring assembly further includes:

[0070] The motor 10 is fixed to the bottom of the tank body 1, and the output shaft of the motor 10 is fixed to the rotating shaft 3.

[0071] Working principle: When in use, first connect the two feeding pipes 9 to two screw conveyors respectively, and use the two screw conveyors to convey manganese ore and silica respectively;

[0072] When feeding, first turn on the switch of one of the screw conveyors to convey manganese ore. The manganese ore enters one of the feeding pipes 9 through the screw conveyor, and then enters one of the weighing tanks 5 through the corresponding valve 11 and hose 12. As the manganese ore enters the weighing tank 5, under the action of gravity, the connecting frame 4 and the two weighing tanks 5 as a whole descend, thereby driving the connecting rod 14 to descend. During the descent of the connecting rod 14, the spring 7 is compressed through the connecting plate 6, so that the force sensor 8 generates a signal. As the manganese ore is input, the signal intensity generated by the force sensor 8 gradually rises. When the total amount of manganese ore in the weighing tank 5 reaches a certain level, the controller closes the switch of the valve 11, and then closes the switch of this screw conveyor to complete the weighing and adding of manganese ore;

[0073] Similarly, use another screw conveyor, as well as another feeding pipe 9, valve 11 and hose 12 to complete the weighing and adding of silica;

[0074] When the weighing of both manganese ore and silica is completed, turn on the switch of the electric push rod 17. When the electric push rod 17 works, the plug 19 descends through the rod body 18, so that the bottom opening of the weighing tank 5 is opened, and then the manganese ore or silica in the weighing tank 5 can fall into the bottom of the tank body 1. At this time, turn on the switch of the motor 10. When the motor 10 works, it drives the rotating shaft 3 to rotate. During the rotation of the rotating shaft 3, the two weighing tanks 5 are driven to rotate through the connecting frame 4. Thus, during the process of the manganese ore or silica in the weighing tank 5 being put into the tank body 1, the manganese ore and silica can be evenly dispersed in the tank body 1 as the weighing tank 5 rotates, so as to realize the preliminary mixing of the manganese ore and silica;

[0075] As the rotating shaft 3 rotates, it drives each stirring rod 13 to rotate, and then the manganese ore and silica in the tank body 1 are mixed again through the stirring rod 13, which ensures the mixing effect of the manganese ore and silica and improves the working efficiency at the same time.
