Description
Technical Field
[0001] The utility model belongs to the technical field of powder uniform mixers, in particular to a uniform mixer for ultrafine powders. Background Art
[0002] Powder mixing refers to the process of uniformly mixing two or more powders of different compositions. If necessary, the same powders of different particle sizes can be mixed evenly, which is called batching. The uniformity of material mixing not only affects the forming process and the quality of the green compact, but also seriously affects the sintering process and the quality of the final product. Mechanical mixing methods use various mixers, such as resonance mixers, ball mills, V-type, barrel-type, cone-type or spiral mixers, etc.
[0003] Existing powder mixers usually stir the powder in one direction when mixing powders to achieve the purpose of mixing the powders. However, there are certain defects in this. The ultrafine powder rotates in one direction during stirring, resulting in uneven mixing of the internal powders. The mixture needs to be stirred again, which cannot achieve the purpose of quickly and effectively mixing the ultrafine powders. Utility Model Content
[0004] The purpose of the utility model is to provide a uniform mixer for ultrafine powders, which solves the problem that the ultrafine powders rotate in one direction during stirring, resulting in uneven mixing of the internal powders, requiring re-stirring of the mixture, and failing to achieve quick and effective mixing of the ultrafine powders.
[0005] In order to solve the above technical problems, the present invention is implemented through the following technical solutions: The present invention is a uniform mixer for ultrafine powder, comprising a frame assembly, a stirring barrel is driven and controlled on the frame assembly, a stirring assembly is movably connected inside the frame assembly, the stirring assembly comprises a spiral stirring blade, both ends of the spiral stirring blade are fixedly connected to a rotating member, the middle part of the rotating member is fixedly connected to a rotating shaft, a movable cavity is raised on the surface of the rotating shaft, the interior of the movable cavity is hollow and one end is fixedly connected to a driving member, one end of the driving member is rotatably connected to a bevel gear, side bevel gears are respectively meshed at both ends of the surface of the bevel gear, the back of the side bevel gear passes through the bevel gear and is fixedly connected to a stirring paddle.
[0006] Furthermore, a feed port is fixedly connected to the top of the mixing barrel, a hopper is fixedly connected to the inner cavity wall of the feed port, and the bottom of the hopper is tapered and gradually moves toward the middle.
[0007] Furthermore, a discharge port is provided at one end of the mixing barrel, and a baffle is inserted above the discharge port.
[0008] Furthermore, the bottom of the inner cavity of the mixing barrel is arc-shaped, and the bottom of the spiral stirring blade is attached to the inner cavity wall of the mixing barrel.
[0009] Furthermore, the frame assembly includes a support frame fixedly connected to the bottom of the mixing barrel, one end of the mixing barrel is movably connected to a transmission member, a transmission belt is sleeved on the side of the transmission member, a transmission shaft is movably connected below the transmission belt, and one end of the transmission shaft is fixedly connected to a motor.
[0010] Furthermore, the transmission member passes through the side of the mixing barrel and is fixedly connected to the inner wall of the mixing barrel with the rotating member.
[0011] Furthermore, a fixing plate is fixedly connected to the bottom of the motor.
[0012] The utility model provides a uniform mixer for ultrafine powders. Compared with the prior art, it has the following beneficial effects:
[0013] 1. A uniform mixer for ultrafine powders, which drives a rotating member movably connected inside a mixing barrel to rotate through a transmission member. The rotating member drives a spiral stirring blade to stir the ultrafine powder inside the mixing barrel while the rotating member rotates. Since the rotating shaft and the rotating member are fixedly connected, the rotating shaft rotates when the rotating member rotates. When the driving member rotates, the side bevel gears engaged at both ends of the bevel gear drive the stirring paddle to stir the ultrafine powder synchronously while the spiral stirring blade stirs the ultrafine powder, thereby avoiding uneven mixing caused by the powder rotating in the same direction during stirring.
[0014] 2. A uniform mixer for ultrafine powders uses a hopper installed inside the feed port. When the powder enters the mixing barrel from the feed port for mixing, the powder may escape from the device through the feed port due to being too fine, which may cause a dust explosion when encountering fire. The hopper can control the powder inside the mixing barrel during mixing to prevent it from overflowing. BRIEF DESCRIPTION OF THE DRAWINGS

The driving member 232 is used to drive the bevel gear 230 to rotate, and the bevel gear 230 is used to drive the side bevel gears 240 meshed at both ends to rotate synchronously. Since the spiral stirring blade 21 and the rotating shaft 23 are both driven to rotate by the rotating member 22, the stirring paddle 24 can synchronously stir the powder stirred inside the spiral stirring blade 21 when rotating, thereby improving the mixing efficiency.
