Abstract

The invention discloses a graphite powder grinding and screening device for a television picture tube. The graphite powder grinding and screening device comprises a base, a grinding box, a grinding ship, a preliminary screening plate, a ball screw, a grinding wheel, a shunt screening plate and a second driving motor. The grinding ship is slidably installed on a sliding rod. The preliminary screening plate is installed at the bottom of the grinding ship. A left moving block and a right moving block are installed on a left thread and a right thread of the ball screw. The other end of a third connecting rod is rotationally installed on a rotating shaft of the grinding wheel. The shunt screening plate is further installed in the grinding box. A tooth part of an incomplete gear is connected with a rack in a meshing mode. Compared with moving grinding of an ordinary grinding wheel in a grinding ship, according to the grinding device, through matching of left-right moving of the grinding ship and the grinding wheel, grinding can be conducted, meanwhile, left-right moving for screening can be conducted, so that the efficiency of grinding and screening is improved, meanwhile, the grinding box is indirectly driven to move up and down through the second driving motor, thus the speed of screening is improved, impurities of larger particles automatically enter an impurity box, and the graphite powder grinding and screening device for the television picture tube is simple and effective.

Description

technical field [0001] The invention relates to a grinding device, in particular to a graphite powder grinding and screening device for a television picture tube. Background technique [0002] Graphite powder is soft, dark gray; it has a greasy feeling and can contaminate paper. The hardness is 1-2, and its hardness can increase to 3-5 along with the increase of impurities along the vertical direction. The specific gravity is 1.9~2.3. Under the condition of isolating oxygen, its melting point is above 3000°C, and it is one of the most temperature-resistant minerals. The chemical properties of graphite powder are relatively stable at room temperature, insoluble in water, dilute acid, dilute alkali and organic solvents; the material has high temperature resistance and electrical conductivity, and can be used as refractory materials, conductive materials, wear-resistant lubricating materials; used in the electrical industry for manufacturing Electrodes, brushes, carbon rods,...
