Detailed Implementation

[0019] The following are specific implementation cases and appendices. Figures 1 to 4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0020] A device for detecting the composition of metallic materials, such as Figures 1 to 4 As shown, the metal material composition detection device includes: a support base 10, a moving mechanism 12, a storage cylinder 13, a partition 14, a guide hole 15, a feeding shaft 16, a stirring shaft 18, a stirring blade 19, a guide frame 20, a guide trough 21, a storage tank 22, and a clamping mechanism 23; the support base 10 is provided with a storage chamber 11; the moving mechanism 12 is installed on the top of the support base 10; the storage cylinder 13 is a hollow cavity with openings at both the top and bottom, and the storage cylinder 13 is connected to the moving mechanism 12; the partition 14 is installed inside the storage cylinder 13, and the partition 14 divides the interior of the storage cylinder 13 into a storage chamber and a guide chamber; the guide hole 15 is provided inside the partition 14; the feeding shaft 16 is provided with a feeding trough 17, the feeding shaft 16 is located in the guide chamber, and both ends of the feeding shaft 16 are connected to the storage cylinder 13. The material is rotatably connected, and the feeding trough 17 is located below the guiding hole 15; the stirring shaft 18 is located in the storage cavity, and both ends of the stirring shaft 18 are rotatably connected to the storage cylinder 13; at least two stirring blades 19 are connected to the outer wall of the stirring shaft 18; the guide frame 20 has hollow cavities with openings at both the upper and lower ends, the cross section of the guide frame 20 is trapezoidal, the guide frame 20 is installed in the storage cylinder 13, and the top opening of the guide frame 20 is located below the feeding shaft 16; the guiding trough 21 is set on the top of the support base 10, and the guiding trough 21 is located below the bottom opening of the guide frame 20; multiple liquid storage tanks 22 are placed in the storage tank cavity 11, and the multiple liquid storage tanks 22 are located below the guiding trough 21; multiple clamping mechanisms 23 are installed in the storage tank cavity 11, and the clamping mechanisms 23 clamp the liquid storage tanks 22.

[0021] By installing the moving mechanism 12 on the top of the support base 10 and connecting the storage cylinder 13 to the moving mechanism 12, the moving mechanism 12 can drive the storage cylinder 13 to move, thereby adjusting the position of the storage cylinder 13. By installing the partition 14 inside the storage cylinder 13 and setting the guide hole 15 inside the partition 14, the partition 14 divides the interior of the storage cylinder 13 into a storage chamber and a guide chamber, so that the material in the storage chamber can flow downward into the guide chamber through the guide hole 15. By rotatably connecting both ends of the feeding shaft 16 to the storage cylinder 13 and positioning the feeding trough 17 inside the feeding shaft 16 below the guide hole 15, the material flowing out of the guide hole 15 can flow into the feeding trough 17. Thus, when the feeding trough 17 stores a predetermined amount of material, the feeding shaft 16 is rotated 180 degrees to pour out the material in the feeding trough 17. By rotatably connecting both ends of the stirring shaft 18 to the storage cylinder 13 and connecting multiple stirring blades 19 to the outer wall of the stirring shaft 18, the stirring shaft 18 can drive multiple stirring blades 19 to rotate, thereby enabling the stirring blades 19 to stir the material stored in the storage chamber. At the same time, it can also prevent the material from accumulating at the guide hole 15, thus improving the material discharge effect. By installing the guide frame 20 inside the storage cylinder 13, with the top opening of the guide frame 20 located below the discharge shaft 16, the material poured out by the discharge shaft 16 can flow into the guide frame 20, thereby enabling the material to flow out through the bottom opening of the guide frame 20. By setting the guide trough 21 on top of the support base 10, so that the guide trough 21 is below the bottom opening of the guide frame 20, and placing multiple liquid storage tanks 22 in the storage tank cavity 11, and placing the multiple liquid storage tanks 22 below the guide trough 21, the material flowing out of the guide frame 20 can flow into the liquid storage tank 22 through the guide trough 21, thereby realizing the chemical reaction between the material and the titration reagent in the liquid storage tank 22 to detect the metal content; by installing the clamping mechanism 23 in the storage tank cavity 11 and clamping the liquid storage tank 22 with the clamping mechanism 23, the stability of the liquid storage tank 22 is improved.

[0022] When using the product, first pour different types of titration reagents into the storage tank 22, and place the storage tank 22 in the storage chamber 11 so that the clamping mechanism 23 clamps the storage tank 22; then, place the material into the storage chamber of the storage cylinder 13; then, start the moving mechanism 12 to move the storage cylinder 13, so that the storage cylinder 13 is above one of the storage tanks 22; at this time, the material in the storage chamber will flow into the discharge trough 17; then, rotate the lower... The feeding shaft 16 is rotated 180 degrees, so that the opening of the feeding trough 17 faces downwards, and the outer wall of the feeding shaft 16 can close the guide hole 15. At this time, the material in the feeding trough 17 flows into the storage tank 22 through the guide frame 20 and the guide trough 21, so that the material reacts chemically with the titration reagent to detect the metal content. Then, the moving mechanism 12 is activated to pour the material in the storage cylinder 13 into different storage tanks 22, so as to detect the content of different types of metal components.

[0023] Using the above-described mechanism, the moving mechanism 12 drives the storage cylinder 13 to move, allowing the material in the storage cylinder 13 to flow into different liquid storage tanks 22. This enables the material to react with different types of titration reagents to detect the content of different metal components. By rotating the feeding shaft 16, the material is quantitatively discharged, replacing manual weighing and thus improving work efficiency.

This allows only one drive device to drive the feeding shaft 16 and the stirring shaft 18 to rotate synchronously, thus reducing the production cost of the product.
