Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy mixing equipment, in particular to a powder metallurgy mixer. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metal powder) as raw material, and then forms and sinters it to produce metal materials, composite materials and various types of products. Mixers are commonly used equipment in the powder metallurgy industry. Their function is to mix two or more powder metallurgies evenly. Existing powder metallurgy mixers have two rotation modes: one is to rotate along the vertical axis; the other is to rotate along the horizontal axis.

[0003] The prior art has the following deficiencies: Application No. 202123283837.6 in the prior art proposes a powder metallurgy mixer, including a base, the upper surface of the base is symmetrically fixedly connected to side plates on both sides, a mixing tank is provided between the two side plates, and both ends of the mixing tank are fixedly connected to connecting pipes, and the two connecting pipes pass through the corresponding side plates and are rotatably connected to the side plates. In the utility model, the mixing tank and the scraper plate can be driven to rotate respectively, so that the materials inside the mixing tank can be fully mixed, greatly improving the mixing effect, and the scraper plate can be separated from the inner wall of the mixing tank during mixing by setting the second drive mechanism, the telescopic mechanism and the third drive mechanism, so as to avoid wear caused by long-term contact, thereby increasing the service life, and the scraper plate contacts and rotates with the inner wall of the mixing tank during discharging, and scrapes off the materials adhering to the inner wall of the mixing tank, thereby avoiding waste.

[0004] When in use, the above-mentioned equipment adopts the first motor and the second motor to drive the mixing tank and the scraper plate to rotate, so as to achieve the mixing effect. Since the structure of the scraper plate is relatively simple, the scraper plate has a low stirring effect on the metallurgical powder inside the mixing tank. Even if the mixing tank and the scraper plate are combined, it is difficult to achieve a good mixing effect. At the same time, the collision and friction between the internal materials of the mixing tank during the metallurgical powder stirring process are likely to generate large noise, affecting the sound environment where the equipment is located.

[0014] Compared with the prior art, the utility model provides a powder metallurgy mixer, which has the following beneficial effects:

[0015] 1. A powder metallurgy mixer is provided with a rotating rod, a stirring rod, a spiral stirring mechanism, a contact ring, and a contact plate. The second motor drives the rotating rod to rotate, and the rotating rod drives the spiral stirring mechanism and the stirring rod to stir the metallurgical powder in the mixing tank.
