Description

Technical Field

[0001] The utility model relates to the technical field of alloy powder processing, in particular to a material feeding structure of a mixer for preparing high temperature resistant iron-based alloy powder. Background Art

[0002] Alloy powder refers to a mixed powder formed by two or more metal or non-metal elements. Methods for preparing alloy powder usually include mechanical alloying, physical alloying, chemical synthesis, etc. Alloy powder usually has better properties than single metal or non-metal powder, such as higher strength, hardness, wear resistance, conductivity, etc. Alloy powder is widely used in 3D printing, metal injection molding, powder metallurgy and other processes. In these processes, alloy powder can be heated, melted, pressed and molded to obtain the required parts. This processing method can greatly improve material utilization and reduce material waste.

[0003] The existing Chinese patent with publication number CN111889062U discloses a mixing device and method for preparing metal alloy powder, and relates to the technical field of alloy powder processing. The present invention comprises a tank body, a mixing cavity is fixedly opened inside the tank body; a group of damping buffers distributed in a circumferential array are fixedly connected to the side surface of the tank body; two symmetrically arranged vibration motors are fixedly connected to the bottom of the tank body; a liquid storage cavity is fixedly opened on the inner wall of the tank body; a circulating liquid inlet pipe and a circulating liquid outlet pipe are fixedly installed on the side surface of the tank body; one end of the circulating liquid inlet pipe and the circulating liquid outlet pipe are both connected to the liquid storage cavity; and two symmetrically arranged storage boxes are fixedly connected to the top surface of the tank body. The present invention changes the static single stirring of traditional materials into dynamic multiple stirring by the design of the turning mechanism. When working, the spiral feeding assembly can drive the material to reciprocate and circulate the above flow. Through the above flow effect, the material can be circulated for stirring and grinding. However, the material is unloaded by the auger when unloading the material of the device. However, since the bottom of the tank body is conical, the material is easily retained at the bottom. If it is not cleaned for a long time, it is easy to accumulate, which affects the unloading problem. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model proposes a feeding structure of a high-temperature resistant iron-based alloy powder preparation mixer. The motor is started to drive the output rod to drive the support rod to rotate, the support rod then drives the bottom scraper rod to rotate, and the bottom scraper rod drives the side wall scraper rod to rotate. When the scraper assembly is mixing the powder normally, the resistance of the powder is relatively large.

[0013] 2. The utility model proposes a feeding structure of a mixer for preparing high-temperature resistant iron-based alloy powder. When the feeding base needs to be cleaned regularly and finally, in order to better clean the adsorbed residues, the elliptical slider can be driven to rotate by rotating the lever, so that the elliptical slider squeezes the fixed ring, so that the friction between the bump on the fixed ring and the slide groove increases, making the slide rod difficult to slide, and then the scraper rod is difficult to rebound, and the hard residue can be cleaned by repeated impact, and finally the scraper rod can be replaced in time, thereby improving the flexibility of use of the entire device.
