Description

Technical Field

[0001] The utility model relates to the technical field of fine powder mixing, and more specifically, to an automatic mixing device for diamond fine powder. Background Art

[0002] Diamond fine powder is a new type of superhard and ultra-fine abrasive formed by special process treatment of synthetic diamond single crystals. In the production process of diamond fine powder, a mixing device is required to mix different raw materials. However, in the process of using the common mixing device, it is necessary to add the materials into the device and mix them through a stirring mechanism. Not only is the feeding uniformity poor, but also the stirring and mixing time is long. At the same time, it is impossible to turn the materials in the vertical direction, reducing the mixing effect and efficiency.

[0003] For example, a diamond fine powder mixing device disclosed in the patent publication No. CN212549233U includes a mixing barrel and stirring blades. There is an upper-position motor in the middle of the top of the mixing barrel, feeding ports are arranged on both sides of the upper-position motor, a bearing seat is arranged below the mixing barrel, a control panel is arranged above the bearing seat, legs are arranged below the bearing seat, a discharge port is arranged at the bottom of the mixing barrel, and an upper-position rotating shaft is arranged above the middle inside the mixing barrel.

[0004] It can be seen from the above disclosed solution that different raw materials are added into the mixing barrel through two feeding ports, which will cause the raw materials to accumulate. Mixing the materials through the stirring blades takes a long time cycle, reducing the working efficiency, and it is impossible to turn the materials at the bottom of the mixing barrel upward, reducing the mixing effect.

The bottom of the mixing cylinder 2 is arc-shaped and is provided with a diversion pipe 24, which is convenient for guiding the pre-mixed raw materials onto the surface of the top plate 51. One end of the mixing tank 1 is fixedly installed with a mixing cylinder 2 and a motor 4. The motor 4 belongs to the prior art and can drive the stirring shaft 41 to rotate clockwise, thereby driving the cloth plate 5, the stirring blades 43 and the spiral blades 44 to rotate and mix the materials. One end of the mixing cylinder 2 is fixedly sleeved with a first feeding pipe 21 and a second feeding pipe 22. Measuring valves are arranged on the surfaces of the first feeding pipe 21 and the second feeding pipe 22. A switching valve is arranged on the surface of the discharge pipe 12. A pre-mixing chamber 23 is arranged inside the mixing cylinder 2. A support shaft 33 is fixedly connected to the inner wall of the pre-mixing chamber 23. The surface of the support shaft 33 is rotationally connected with a rotating cylinder 3 through axially symmetric sealing bearings 32. A mixing plate 31 is fixedly connected to the surface of the rotating cylinder 3. The output end of the motor 4 is provided with a stirring shaft 41. Stirring frames 42, spiral blades 44 and cloth plates 5 are fixedly installed on the surface of the stirring shaft 41. Stirring blades 43 are fixedly connected to the side surface of the stirring frame 42. The stirring shaft 41, the stirring blades 43, the stirring frames 42, the spiral blades 44 and the cloth plates 5 are combined to form a mixing mechanism. Equally spaced cloth holes 52 are arranged on the surface of the cloth plate 5. The cloth holes 52 are convenient for the flowing raw materials to fall downward into the mixing tank 1, avoiding the accumulation of raw material feeding.

[0027] The shape of the cloth plate 5 is umbrella-shaped. Reinforcing ribs 53 are arranged at equal intervals in a ring at the bottom of the cloth plate 5. One end of the reinforcing rib 53 is fixedly connected to a top plate 51. The top plate 51 is made of wear-resistant plate. The top plate 51 can reduce the wear of the raw materials on the cloth plate 5 and extend the service life of the cloth plate 5. The two ends of the stirring frame 42 are arc-shaped, and the radian is the same as the radian of the bottom of the inner wall of the mixing tank 1. A connecting sleeve is arranged at the middle position of the stirring frame 42, and the connecting sleeve is detachably connected to the surface of the stirring shaft 41 through bolts. The bottom radian of the stirring frame 42 can fit the bottom of the inner wall of the mixing tank 1, improving the stirring effect of the raw materials.

Then, different diamond micropowder raw materials are added into the mixing cylinder 2 through the first feeding pipe 21 and the second feeding pipe 22. At the same time, the downward feeding thrust of the raw materials pushes the mixing plate 31 to rotate, so that the added raw materials are dispersed and pre-mixed. Then, they are guided through the diversion pipe 24 to the surface of the top plate 51 of the rotating cloth plate 5, and then the raw materials are spread out and fed downward. The raw materials are added to the bottom of the mixing tank 1 and are horizontally stirred and mixed by the rotating stirring blades 43. At the same time, they are vertically turned over and mixed by the spiral blades 44. The mixing mechanism composed of the stirring shaft 41, the stirring frame 42, the stirring blades 43, the spiral blades 44 and the cloth plate 5 integrates uniform feeding, mixing and turning over, greatly improving the mixing effect of the mixing device.
