For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0020] Reference Figure 1-4 The utility model provides an embodiment: an automatic bead adding device for a vertical sand mill, comprising a bearing box 1, wherein the lower side of the bearing box 1 is connected to an organic seal 2, the lower end of the organic seal 2 is connected to an organic seal pressure plate 3, the right end of the organic seal 2 is connected to a flange threaded pipe 4, the flange threaded pipe 4 is connected to a funnel joint 5, the flange threaded pipe 4 and the funnel joint 5 are provided with an automatic bead adding mechanism 6, the right side of the bearing box 1 is provided with a bead adding port 7, the bead adding port 7 and the flange threaded pipe 4 are positioned correspondingly and cooperate with each other, during the conveying process of the material, because there is enough gap between the conveying pipe and the spiral body and the distance is extremely short, even if there is stirring and turning, the power consumption is very small, because the device conveys grinding zirconium beads with uniform particles, which have high density, are not easy to break, not deteriorate, not sticky, not agglomerate, and do not contain long fibers and impurities, and can be used with confidence without any worries.
[0021] The funnel joint 5 is connected to a bearing sleeve 8, a motor bracket 9 is connected to the bearing sleeve 8, a shaft sleeve 10 is connected to the bearing sleeve 8, the shaft sleeve 10 is connected to the motor bracket 9, a single mirror stainless steel sheet 11 is connected between the bearing sleeve 8 and the shaft sleeve 10, the automatic bead adding mechanism 6 includes a reduction DC motor 61, which is driven by the reduction DC motor 61. Under the premise of ensuring continuous torque output, due to the extremely low speed, there will naturally be no obvious wear of the screw and the sleeve. The reduction DC motor 61 is connected to the motor bracket 9, and the output end of the reduction DC motor 61 is connected to a feeding screw. 62, the feed screw 62 is installed in the flange threaded tube 4, the upper side of the feed screw 62 is connected with a deep groove ball bearing 63, the deep groove ball bearing 63 and the shaft sleeve 10 are matched with each other in position, the lower side of the deep groove ball bearing 63 is provided with a shaft retaining ring 64, the upper side of the deep groove ball bearing 63 is provided with a gasket 65, the shaft retaining ring 64 and the gasket 65 are installed in the bearing sleeve 8, the flange threaded tube 4 is connected to the funnel joint 5 through the clamp 12, a sealing ring 13 is connected between the clamp 12 and the flange threaded tube 4, the flange threaded tube 4 is connected to the right side of the bearing box 1 and the machine seal 2 at an angle of 60°.
[0022] Working principle: This automatic bead adding device first screws a flange threaded tube 4 into the threaded hole of the bead adding port 7 on the machine seal 2, and then connects the feeding screw 62 with the deep groove ball bearing 63 through the shaft retaining ring 64 and fixes it on the funnel joint 5. Next, insert one end of the feeding screw 62 into the flange threaded tube 4, and then use the quick-release clamp 12 to connect the funnel joint 5 assembly to the quick-connect flange of the flange threaded tube 4. Finally, connect the reduction DC motor 61 to the bearing sleeve 8 with the motor bracket 9, and press the gasket 65 and the single mirror stainless steel sheet 11 between the bearing sleeve 8 and the motor bracket 9 to achieve the sealing effect on the upper opening of the bearing sleeve 8, and then use the shaft sleeve 10 to connect and fix the motor shaft and the shaft head of the feeding screw 62. When the device is working, the pre-dried ground zirconium beads are poured into the funnel joint 5, and the reduction DC motor 61 is started to rotate counterclockwise. Under the uniform push of the spiral blades, the ground beads are smoothly transported to the grinding chamber of the sand mill in turn. When the beads are added, the remaining small amount of zirconium beads can be flushed into the grinding chamber with a long-mouthed spray pot, and then the motor and funnel assembly are removed, and the flange threaded pipe 4 interface is sealed with a blind plate and a hoop 12. The equipment can resume production. The automatic bead adding device with spiral conveying is used to replace the traditional vertical sand mill manual bead adding production mode. It is easy to operate and small in size, but has a certain sealing effect and can play a dust-proof role. The ground zirconium beads with smaller particles can be pushed and fed evenly without accumulation and clogging.
