Description

Technical Field

[0001] This utility model relates to the field of metal powder stirring technology, and in particular to a stirrer for preparing metal powder. Background Technology

[0002] Metal powder refers to a group of metal particles with a size of less than 1 nm, including single metal powder, alloy powder, and certain refractory compound powders with metallic properties. It is the main raw material for powder metallurgy. Metallic elements are generally silvery-white. In the preparation of metal powder, a large number of steps require stirring of the metal powder, which requires a corresponding mixer.

[0003] Currently, traditional metal powder mixers struggle to thoroughly mix powders at different heights and in different areas within the mixing drum, resulting in uneven powder mixing and affecting the molding quality and performance of subsequent products. Furthermore, some existing mixers employ a flat bottom design, which easily leads to powder residue during unloading, requiring manual cleaning. This not only increases labor intensity but also presents problems such as incomplete cleaning and potential contamination. While mixers with a conical bottom offer some advantages in unloading, the powder in the conical area is difficult for the mixing components to fully reach, also resulting in insufficient mixing and difficulty in removing residual powder. Therefore, there is a need to develop a new type of metal powder preparation mixer that can flexibly adjust the mixing position, improve mixing uniformity, and effectively solve the problem of unloading residue. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a mixer for preparing metal powder.

[0005] This utility model is achieved by the following technical solution: a mixer for preparing metal powder, including a mixing drum, a support column fixedly connected to the bottom of the mixing drum, a discharge pipe fixedly connected to the bottom of the mixing drum, a partition fixedly connected inside the mixing drum, a lifting device provided inside the mixing drum, and a support device provided inside the mixing drum.

[0006] The lifting device includes a first drive motor, a lead screw fixedly connected to the output end of the first drive motor, a lifting plate threadedly connected to the surface of the lead screw, a guide rod slidably connected inside the lifting plate, a second drive motor fixedly connected to the top of the lifting plate, and a rotating rod fixedly connected to the output end of the second drive motor.

[0007] With the above technical solution, the bottom of the guide rod is fixed to the top of the partition and passes through the inside of the lifting plate, limiting and guiding the movement of the lifting plate, ensuring that the lifting plate is stable and without deviation during the lifting process, and preventing shaking.

[0008] As a further improvement to the above solution, the inner wall of the stirring cylinder is provided with grooves.

[0009] As a further improvement to the above solution, the first drive motor is located at the top of the stirring tank, and the bottom of the first drive motor is fixedly connected to the top of the stirring tank.

[0010] With the above technical solution, the first drive motor is located at the top of the mixing drum and provides power to the lifting device. Its output end drives the lead screw to rotate, thereby driving the lifting plate to move up and down along the lead screw, so as to realize the adjustment of the height position of the mixing component.

[0011] As a further improvement to the above solution, the bottom of the lead screw is rotatably connected to the inside of the partition, the left and right sides of the lifting plate are slidably connected to the grooves on the inner wall of the mixing cylinder, the bottom of the guide rod is fixedly connected to the top of the partition, and the surface of the rotating rod is rotatably connected to the inside of the partition.

[0012] With the above technical solution, a stirring part is provided at the bottom of the rotating rod surface, and the baffle is located at the bottom.

[0013] As a further improvement to the above solution, the support device includes a hydraulic rod, the telescopic end of which is fixedly connected to a rotating block, the interior of which is rotatably connected to a connecting rod, and one end of which is rotatably connected to an inclined plate.

[0014] Through the above technical solution, the tilting mechanism is located at the bottom of the partition plate and is rotatably connected to the inner wall of the rotating rod on one side. Under the linkage of the hydraulic rod, the rotating block and the connecting rod, it rotates around the inner wall of the mixing drum. After the mixing is completed, it rotates downward to form an inclined slope, which helps the metal powder slide down to the conical bottom of the mixing drum, avoids powder residue, and completes the unloading.

[0015] As a further improvement to the above solution, two hydraulic rods are provided, with one side of the hydraulic rod fixedly connected to the surface of the mixing drum.

[0016] As a further improvement to the above solution, the inclined plate is located at the bottom of the partition, and one side of the inclined plate is rotatably connected to the inner wall of the rotating rod.

[0017] With the above technical solution, two inclined plates are provided, and the inclined plates are located at the bottom of the rotating rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention features a lifting plate. When the first drive motor starts, its output drives the lead screw to rotate. The lifting plate, threadedly connected to the lead screw, moves up and down along the lead screw under the guidance of the guide rod, causing the second drive motor and rotating rod at the top to move. The second drive motor drives the rotating rod to rotate, and the stirring part on the surface of the rotating rod stirs and mixes the metal powder at the bottom of the partition. This allows for operation on metal powder at different heights in the mixing drum, expanding the stirring range, enhancing the three-dimensionality of the stirring, and ensuring that the powder is fully mixed during the up-and-down movement. This significantly improves stirring efficiency and mixing uniformity, meeting the requirements for high-quality metal powder preparation.

[0020] This invention features an inclined plate and two retracting hydraulic rods that drive a rotating block. The rotating block, via a connecting rod, causes the inclined plate to rotate downwards around the inner wall of the mixing drum. The mixed metal powder falls to the conical bottom of the mixing drum and is discharged from the outlet pipe. Compared to ordinary designs where powder easily remains at the bottom and requires repeated manual cleaning, this design not only avoids powder residue but also simplifies the unloading process, improves unloading efficiency, and reduces manual cleaning costs and labor intensity.
