Description
Technical Field
[0001] The utility model belongs to the technical field of finely ground tungsten powder rod production and relates to a dispersing and stirring device for finely ground tungsten powder raw materials. Background Art
[0002] In the production process of PCB milling cutters and PCB drill bits, fine-ground tungsten powder rods are required as the tool handle. Fine-ground tungsten powder rods are generally made by fine-ground tungsten powder. Fine-ground tungsten powder is in powder form. First, it is pressed through the corresponding mold to form a rod shape, and then sintered at high temperature in a sintering furnace. The production process is simple.
[0003] When making fine-ground tungsten rods, it is necessary to first mix tungsten powder with powders of other materials such as carbon powder and stir them evenly. However, the tungsten powder will agglomerate after being reduced in the tungsten powder production process. The presence of a large number of secondary particles is not conducive to mixing tungsten powder with other powders, requiring extended stirring time and reducing stirring efficiency.
[0004] Based on this, we designed a dispersion and stirring device for finely ground tungsten powder raw materials. Utility Model Content
[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose a dispersion and stirring device for fine-ground tungsten powder raw materials.

[0011] With the above structure, when in use, if it is necessary to clean the inside of the mixing drum, the mounting plate connected to the first small plate and the second small plate can be removed, and then the vibrating plate can be pulled out from another mounting hole. At this time, the rotating rod will pass between the first small plate and the second small plate, making it easy to disassemble and install, thereby making it easier for the operator to clean the inside of the mixing drum and the vibrating plate.
[0012] A rubber gasket is provided on the outside of the mounting hole, the rubber gasket is fitted with the inner wall of the mounting hole, and the edge of the connecting plate is against the rubber gasket.
