[0025] like Figure 1 and Figure 2As shown, the present application provides a phosphate tailings weighing device, including a support frame 1, a discharge bin 2 is fixedly provided on the support frame 1, a discharge valve 3 is provided at the discharge port of the discharge bin 2, a weighing component 4 is provided on the support frame 1, and the weighing component 4 is located directly below the discharge port of the discharge bin 2, and a controller 5 is provided on the support frame 1, and the controller 5 is electrically connected to the discharge valve 3. The controller 5 controls the opening or closing of the discharge valve 3, and the opening or closing of the discharge valve 3 is controlled by the controller 5, so that the phosphate tailings in the discharge bin 2 are controlled to fall into the weighing component 4 for weighing, without manual weighing, reducing the workload of the staff, avoiding the weighing instability caused by manual weighing, and ensuring the proportioning accuracy of the cement raw materials.

[0026] like Figure 1 and Figure 2 As shown, the weighing assembly 4 includes a weighing hopper 41, a discharge valve 42, a weighing bracket 43 and a weighing sensor 44. The weighing bracket 43 is fixedly mounted on the support frame 1. A plurality of support columns 431 are fixedly mounted on the weighing bracket 43. A connecting piece 6 is provided at the lower portion of the weighing hopper 41. The connecting piece 6 and the support columns 431 are provided with matching through holes. The support columns 431 are located in the through holes. A spring 7 is sleeved on the support columns 431. The spring 7 is located between the weighing bracket 43 and the connecting piece 6. Specifically, the upper end of the spring 7 is connected to the connecting piece 6, and the lower end of the spring 7 is connected to the weighing bracket 43. The weighing sensor 44 is fixedly mounted on the weighing bracket 43 and is located below the connecting piece 6. The discharge valve 42 is located at the discharge port of the weighing hopper 41. The controller 5 is electrically connected to the weighing sensor 44 and the discharge valve 42. Connection, specifically, during weighing, the discharge valve 42 is in a closed state, the controller 5 controls the discharge valve 3 to open, and the phosphate tailings in the discharge bin 2 fall into the weighing hopper 41. At this time, the weighing hopper 41 moves down under the gravity of the phosphate tailings, the spring 7 is compressed, and the connecting piece 6 moves down with the weighing hopper 41 to squeeze the weighing sensor 44. When the weight of the weighing hopper 41 reaches the set value, the sensor sends a signal to the controller 5, and the controller 5 controls the discharge valve 3 to close, thereby stopping the discharge bin 2 from discharging into the weighing hopper 41, and then the controller 5 controls the discharge valve 3 to open, and discharges the phosphate tailings in the weighing hopper 41, thereby achieving the effect of automatic weighing and automatic control of discharge. When the phosphate tailings in the weighing hopper 41 are discharged, the weighing hopper 41 returns to its initial position under the action of the spring 7.

[0027] like Figure 1 As shown, four support columns 431 are provided, and the four support columns 431 are evenly arranged around the weighing hopper 41. Through the cooperation between the four support columns 431 and the spring 7, the weighing hopper 41 can move up and down stably.

[0028] like Figure 2 As shown, a stirring assembly 8 is provided in the discharge bin 2, and the stirring assembly 8 is used to stir the phosphate tailings in the discharge bin 2. The stirring assembly 8 prevents the phosphate tailings in the discharge bin 2 from piling up and not falling down easily.

[0029] like Figure 2 As shown, the stirring assembly 8 includes a stirring motor 81, a stirring rod 82 and a plurality of stirring shafts 83. The stirring motor 81 is fixedly mounted on the top of the discharge bin 2. The stirring shaft is rotatably mounted in the discharge bin 2. The upper end of the stirring shaft extends to the outside of the discharge bin 2 and is fixedly connected to the output shaft of the stirring motor 81. A plurality of stirring rods 82 are evenly fixed on the stirring shaft 83. The stirring motor 81 is electrically connected to the controller 5. The controller 5 controls the start of the stirring motor 81. The stirring motor 81 drives the rotating shaft to drive the stirring rod 82 to rotate, so as to stir the phosphate tailings in the stirring and discharge bin 2.

[0030] like Figure 2 As shown, both the discharge valve 3 and the outlet valve 42 are electric valves, which facilitates the controller 5 to control the discharge valve 3 and the outlet valve 42 .

[0031] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
