Description

Technical Field

[0001] The utility model relates to a metering device, in particular to a metering device for the production of slag powder. Background Art

[0002] Slag powder metering refers to the accurate metering and control of slag powder during the production process to ensure its precise dosage in mixing, processing or transportation. As an industrial by-product, slag powder is widely used in building materials industries such as cement and concrete. To ensure product quality and process stability, the metering of slag powder is crucial:

[0003] After long-term use, mechanical and some electronic metering devices may experience a decline in accuracy due to factors such as wear, vibration or dust accumulation. Especially when dealing with fine-grained slag powder, the change in the fluidity of the powder will affect the metering accuracy.

[0004] It should be noted that the above content belongs to the technical cognitive scope of the utility model person and does not necessarily constitute the prior art. Content of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide a metering device for the production of slag powder.

[0006] To achieve the above purpose, the utility model provides a metering device for the production of slag powder, including a chassis:

[0007] At the middle positions on both sides of the chassis, side frames are fixedly provided. At the tops of the two side frames, axle frames are fixedly provided. The two sides of the two axle frames are rotationally connected to the two sides of a turntable through rotating shafts. A lever frame is fixedly provided on the top of the turntable. One end of the lever frame is connected to a metering plate through a limiting structure. The other end of the lever frame is fixedly provided with a rear seat frame. A first magnetic disk is fixedly provided at the bottom of the rear seat frame. On one side of the top of the chassis, a support seat is fixedly provided. A top column is fixedly provided at the top of the support seat. A second magnetic disk is fixedly provided at the top of the top column.

[0008] In one example, at one end of one side of the chassis, a fixed frame is fixedly provided. On one side of the top of the fixed frame, a top seat is fixedly provided. An electric telescopic rod is inserted through the top of the top seat. The telescopic end of the electric telescopic rod is fixedly provided with a top head.

[0009] In one example, the limiting structure includes a sleeve sliding seat inserted and connected to the lever frame. A limiting bolt is threadedly connected to the top of the sleeve sliding seat. A knob is fixedly provided at the top of the limiting bolt.

[0010] In one example, the first magnetic disk and the second magnetic disk are magnetically connected, and the size of the first magnetic disk matches the size of the second magnetic disk.

[0011] In one example, the inclination angle of one side of the inner wall of the metering tray is 20°-30°.

[0012] The metering device for slag powder production proposed by the present utility model can bring the following beneficial effects:

[0013] The present utility model includes a chassis, a side frame, a metering tray, a side frame, a lever frame, a support seat, a top column, a first magnetic disk, a rear seat frame, a fixed frame, a top seat, an electric telescopic rod, a top head, a second magnetic disk, a sleeve sliding seat, a knob, a limit bolt and a turntable. The slag powder is placed inside the metering tray. When the weight of the slag powder reaches the threshold weight, and the threshold weight is greater than the attraction between the first magnetic disk and the second magnetic disk, the lever frame tilts and the slag powder slides out, thus completing the metering. The lever structure can be designed with different sensitivities and range ranges according to actual needs to adapt to slag powder with different densities, fluidities and particle sizes, with high flexibility and less affected by external factors (such as dust, humidity, temperature, etc.), and can maintain the metering accuracy and stability for a long time.

[0025] As Figures 1 to 3 shown, an embodiment of the present utility model provides a metering device for slag powder production, including a chassis 1:

[0026] On both sides of the middle position of the chassis 1, side frames 2 are fixedly provided. At the top ends of the two side frames 2, axle frames 4 are fixedly provided. Both sides of the two axle frames 4 are rotationally connected to both sides of the turntable 18 through rotating shafts. At the top of the turntable 18, a lever frame 5 is fixedly provided. One end of the lever frame 5 is connected to the measuring disk 3 through a limiting structure. At the other end of the lever frame 5, a rear seat frame 9 is fixedly provided. At the bottom of the rear seat frame 9, a first magnetic disk 8 is fixedly provided. On one side of the top end of the chassis 1, a support seat 6 is fixedly provided. At the top of the support seat 6, a top column 7 is fixedly provided. At the top of the top column 7, a second magnetic disk 14 is fixedly provided.

[0027] Specifically, at one end of one side of the chassis 1, a fixed frame 10 is fixedly provided. At one side of the top end of the fixed frame 10, a top seat 11 is fixedly provided. An electric telescopic rod 12 is inserted through the top end of the top seat 11. The telescopic end of the electric telescopic rod 12 is fixedly provided with a top head 13.

[0028] Specifically, the limiting structure includes a sleeve sliding seat 15 inserted and connected to the lever frame 5. A limiting bolt 17 is threadedly connected to the top end of the sleeve sliding seat 15. At the top end of the limiting bolt 17, a knob 16 is fixedly provided.

[0029] Specifically, the first magnetic disk 8 and the second magnetic disk 14 are magnetically connected, and the size of the first magnetic disk 8 matches the size of the second magnetic disk 14.

[0030] Specifically, the inclination angle of one side of the inner wall of the measuring disk 3 is 20° - 30°.

[0031] Working principle: When in use, slag powder gradually enters into the measuring disk 3. The weight of the slag powder inside the measuring disk 3 increases. When the slag powder in the measuring disk 3 at one end of the lever frame 5 reaches the slag powder threshold, at this time, the weight inside the measuring disk 3 is greater than the magnetic force, the lever is unbalanced, resulting in the device tipping over. The turntable 18 at the bottom of the lever frame 5 rotates with the two axle frames 4 as the axis, the first magnetic disk 8 and the second magnetic disk 14 are separated, and the slag powder inside the measuring disk 3 drops to complete metering and discharging. Then, turn on the electric telescopic rod 12, and the telescopic end of the electric telescopic rod 12 drives the top head 13 to move downward, applying pressure to the top of the rear seat frame 9 to help the first magnetic disk 8 at the bottom of the rear seat frame 9 attract and reset with the second magnetic disk 14. Slide the sleeve sliding seat 15 to the position on the lever frame 5, and then rotate the knob 16. The limiting bolt 17 at the bottom of the knob 16 limits and fixes the measuring disk 3. By adjusting the position of the measuring disk 3, the measuring range of the device can be enlarged or reduced. The position close to the fulcrum is suitable for large-range weight measurement, while the position far from the fulcrum is suitable for small-range and high-precision measurement.

In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and for the relevant parts, reference can be made to the description of the method embodiment.
