Technical Field

The utility model relates to the technical field related to parts of sand mills, in particular to a feeding end cover structure of a sand mill.

Background

Examples

Referring to fig. 1 and 2, a sand mill feeding end cover structure comprises a feeding cover plate 1, wherein a feeding pipe 2 for providing initial kinetic energy consistent with the rotation direction of a dispersion disk of a sand mill for materials passing through the feeding pipe 2 is arranged on the feeding cover plate 1, the outlet end of the feeding pipe 2 is fixedly connected with one side surface of the cover plate, and the inlet end is obliquely arranged upwards. The feeding pipe 2 is obliquely arranged, and after materials enter the grinding cylinder under the conveying force of the material pump and the gravity of the feeding pipe, the materials still have kinetic energy after entering from the feeding pipe 2, the kinetic energy does not need to be provided by the dispersion disc, and the kinetic energy does not need to be provided by the dispersion disc again through the law of conservation of energy, so that the effect of saving electric energy is achieved.

The distance between the outlet end of the feed pipe 2 and the central position of the feed cover plate 1 is more than 0 and less than or equal to the radius of the dispersion disc of the sand mill, so that the material passing through the feed pipe 2 reaches the position of the dispersion disc close to the edge.

The distance between the outlet end of the feed pipe 2 and the central position of the feed cover plate 1 is equal to the radius of a dispersion disc of the sand mill, and materials can directly reach the maximum linear velocity position of the dispersion disc after entering through the feed pipe 2 and can directly rotate at a high speed along with grinding media at the maximum linear velocity position of the dispersion disc, so that the materials do not need to be thrown to the maximum linear velocity position of the edge through the acceleration of the dispersion disc.

The closer the distance between the outlet end of the feed pipe 2 and the central position of the feed cover plate 1 is to the radius of the dispersion disc, the smaller the mechanical energy provided by the dispersion disc for accelerating the materials after the materials enter the grinding cylinder, and the better the energy-saving effect.

The outlet end of the feed pipe 2 is positioned at the middle upper part of the feed cover plate 1, so that the initial kinetic energy obtained by the material passing through the feed pipe 2 is larger. The smaller the mechanical energy provided by the material acceleration is, the further energy-saving effect is improved.

The included angle between the feeding pipe 2 and the feeding cover plate 1 is 10-45 degrees. The included angle between the feeding pipe 2 and the feeding cover plate 1 affects the angle of the material entering the grinding cylinder, and also affects the initial kinetic energy of the material entering the grinding cylinder, the angle is too small, and although the kinetic energy is larger, certain friction exists between the material and the feeding cover plate 1 when the material falls, and a part of energy is lost; and too large an angle, the kinetic energy will be reduced. By experimental contrast, when the angle between the feed pipe 2 and the feed cover plate 1 is 20 degrees, the initial kinetic energy of the material entering the grinding cylinder is kept to be the maximum.

The inlet end of the feed pipe 2 is provided with a flange connection disc 3 which is convenient for connecting a material pump. And the flange connection disc 3 is convenient to be connected with a material pump quickly.

When the sand mill is in actual use, the position of the feeding pipe 2 is determined according to the rotating direction of the dispersion disc of the sand mill, the direction of the material entering the grinding cylinder is ensured to be consistent with the rotating direction of the dispersion disc, then the feeding pipe 2 is connected with the material pump, the material enters the grinding cylinder through the feeding pipe 2, the initial kinetic energy is obtained because of the thrust of the conveying pump and the gravity of the material, the material reaches the position close to the maximum linear speed of the dispersion disc, and the material can rotate along with the grinding medium all the time, so that the electric energy consumed by the acceleration of the material through the dispersion disc and the time required by the acceleration are saved.

The present utility model is not limited to the above embodiments, and any person skilled in the art can easily think about the changes or substitutions within the technical scope of the present utility model, and the changes or substitutions are intended to be covered by the scope of the present utility model; embodiments of the utility model and features of the embodiments may be combined with each other without conflict.
