SUMMERY OF THE UTILITY MODEL
The utility model discloses a main objective provides a novel sand mill, problem in can effectual solution background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a novel sand mill comprises a barrel body, an upper end cover seat, a main shaft and a stirring disc, wherein a plurality of stirring rods a are arranged at positions close to the upper end cover seat for stirring, the inner surface of the stirring disc is in transmission connection with the main shaft through a planetary reduction gear, the outer surface of the main shaft is positioned at the position of the inner surface of the barrel body and is positioned between the stirring discs, a longitudinal stirring sleeve is sleeved at the position of the inner surface of the barrel body of the outer surface of the main shaft and is positioned between the upper end cover seat and the stirring disc, the main shaft is in meshing transmission with the longitudinal stirring sleeve, a plurality of stirring rods b are arranged at the outer surface of the longitudinal stirring sleeve, the structures of the stirring rods a and the stirring rods b are the same, when the novel sand mill is used, the main shaft rotates to drive the longitudinal stirring sleeve to rotate, the main shaft brick rotates to drive the stirring disc to rotate through the planetary reduction gear, the, the grinding slurry rotational speed that vertical stirring cover drove is fast, because near the vertical stirring cover of centrifugal effect grinding slurry near can extrude the grinding slurry that is located the stirring dish position, and then can play supplementary effect of grinding, can avoid traditional grinding mode grinding dish to drive grinding slurry simultaneously and rotate near centrifugal force makes the intensive concentration of medium near the staving inner wall, help the distribution of grinding medium, and the stirring rod an and the stirring rod b that set up can further improve the motion of grinding medium, improve grinding effect.
Further, stirring rod a sets up in the position of stirring a set surface and keeping away from stirring rod b, and the stirring dish surface that stirring rod b position was put is smooth promptly, does not set up stirring rod a, and then here can not influence the rotation of oar liquid when the pivoted, can not disturb near vertical stirring cover grinding thick liquid and can extrude the grinding thick liquid that is located the stirring dish position.
Further, the length of stirring rod b diminishes in proper order from the position of staving top and bottom to the position in the middle of the main shaft, and the length of the stirring rod b that is close to the staving bottom is greater than the length of the stirring rod b that is close to the staving top, and stirring rod b forms a shape similar to the round platform as a whole promptly, and during the rotation, there is the effect of pushing up the oar liquid, can reduce the oar liquid because the heavy end of self gravity.
The working principle and the beneficial effects are as follows: the longitudinal stirring sleeve is driven to rotate through the rotation of the main shaft, and the stirring disc is driven to rotate through the rotation of the main shaft through the planetary reduction gear, so that the problems in the background art can be effectively solved;
(1) stirring the grinding slurry rotational speed that the dish drove in the course of the work slow, the grinding slurry rotational speed that vertical stirring cover drove is fast, because near the grinding slurry of centrifugal vertical stirring cover of effect can extrude the grinding slurry who is located stirring dish position, and then can play the effect of supplementary grinding, can avoid traditional grinding mode grinding dish to drive grinding slurry to rotate because centrifugal force makes near the intensive concentration of medium near the staving inner wall, help the distribution of grinding medium, and the stirring rod an and the stirring rod b that set up can further improve the motion of grinding medium, improve grinding effect.
(2) Set up in the position of stirring a surface and keeping away from stirring rod b through stirring rod a, the stirring dish surface of stirring rod b position is smooth promptly, does not set up stirring rod a, and then here can not influence the rotation of oar liquid when the pivoted, can not disturb near the grinding thick liquid extrusion that vertical stirring overlaps and be located the grinding thick liquid of stirring dish position.
(3) The length of stirring rod b diminishes in proper order from the position of staving top and bottom to the position in the middle of the main shaft, and the length of the stirring rod b who is close to the staving bottom is greater than the length of the stirring rod b who is close to the staving top, and stirring rod b forms a shape similar to the round platform in whole promptly, during the rotation, has the effect of upwards pushing away oar liquid, can reduce oar liquid because self gravity sinks the end.
