[0022] As Figures 1 to 3 ​As shown, the present application provides a laminated separation discharge sand mill, which comprises a sand mill barrel 1, a drive 3 arranged on the sand mill barrel 1, a rotating shaft 2 inserted into the sand mill barrel 1 and rotationally connected with the sand mill barrel 1, a sand mill assembly 4 rotationally arranged in the sand mill barrel 1 and connected with the rotating shaft 2, a screening assembly 5 rotationally arranged in the sand mill barrel 1, and a shaft body discharge channel 6 arranged on the rotating shaft 2. The screening assembly 5 comprises a plurality of separation laminates 7, a plurality of gaskets 8, a connecting rod 9 connected with the rotating shaft 2 at both ends, and a separation cavity 10 arranged through the plurality of separation laminates 7. The gasket 8 is used to separate two adjacent separation laminates 7 and form a separation gap 11 between the two adjacent separation laminates 7. The plurality of gaskets 8 and separation laminates 7 are connected in series through the connecting rod 9. One end of the rotating shaft 2 is inserted into the sand mill assembly 4 and the separation cavity 10 in sequence after penetrating the barrel body of the sand mill barrel 1. The other end of the rotating shaft 2 is connected with the output end of the drive 3. The inlet of the shaft body discharge channel 6 is communicated with the separation gap 11 through the separation cavity 10.

[0023] Specifically, the sand mill further comprises a feed inlet 12 arranged through the barrel body of the sand mill barrel 1, which is arranged on the side of the sand mill barrel 1 away from the screening assembly 5. In actual use, the material and grinding balls are put into the sand mill barrel 1 through the feed inlet 12, the rotating shaft 2 is driven to rotate in the sand mill barrel 1 by the drive 3, the sand mill assembly 4 is driven to rotate in the sand mill barrel 1 by the rotating shaft 2, the grinding balls and the material are driven to rotate in the sand mill barrel 1 by the sand mill assembly 4, and the material is continuously rubbed by the grinding balls, thereby completing the primary sanding of the material. The discharge outlet of the shaft body discharge channel 6 is connected with an external pump body, and under the action of the suction force provided by the external pump body, the material and grinding balls in the sand mill barrel 1 flow into the shaft body discharge channel 6. When the material and grinding balls flow to the screening assembly 5, the material and grinding balls are screened through the separation gap 11 between the two adjacent separation laminates 7. The material and grinding balls with a diameter greater than the width of the separation gap 11 are blocked outside the separation cavity 10 by the separation gap 11, and the material whose particle size is sanded to be smaller than the width of the separation gap 11 flows from the sand mill barrel 1 to the separation cavity 10, and then is transported to the outside of the sand mill barrel 1 through the shaft body discharge channel 6, thereby completing the sanding and screening separation of the material. The structure of the present application is compact and convenient to produce. Since the screening assembly 5 rotates with the rotating shaft 2, the separation gap 11 in the rotating state not only can separate the material and grinding balls, but also can produce relative motion or friction between the separated grinding balls and material and the surface of the separation laminate 7, which can effectively prevent the grinding balls or material from being blocked at the inlet of the separation gap 11, reduce the cleaning and maintenance frequency of the screening assembly 5, and improve the screening efficiency and practicability of the screening assembly 5. The additional separation cavity 10 can accommodate more material, which is conducive to the stable output of the material into the shaft body discharge channel 6. The drive 3 can drive the rotating shaft 2 to rotate by using the existing motor and transmission belt, which will not be described here.

[0024] Further, the sanding barrel 1 further comprises a first cover plate 13 detachably connected with the connecting rod 9 and the rotating shaft 2 respectively, the first cover plate 13 is used to block the opening on one side of the separation cavity 10, and the first cover plate 13 is connected with one end of the connecting rod 9.

[0025] Specifically, the sanding machine further comprises a second cover plate 14 sleeved outside the rotating shaft 2, the second cover plate 14 is used to block the opening on the other side of the separation cavity 10, and the second cover plate 14 is connected with the other end of the connecting rod 9. In the actual installation process, after the sanding assembly 4 is sleeved outside the rotating shaft 2, the second cover plate 14 is connected with the sanding assembly 4 or / and the sanding assembly 4, one end of the connecting rod 9 is fixed with the second cover plate 14 by clamping or screwing, and then a plurality of separation laminations 7 and gaskets 8 are spaced apart and connected in series with the connecting rod 9, finally the first cover plate 13 is screwed or clamped with the connecting rod 9 and the rotating shaft 2, thereby completing the quick connection of the rotating shaft 2 with the screening assembly 5 and the sanding assembly 4. By blocking the separation cavity 10 with the first cover plate 13 and the second cover plate 14, the two ends of the connecting rod 9 are fixed conveniently, and the material can only flow into the shaft body discharge channel 6 through the separation gap 11, which is beneficial to the accurate sanding of the material.

[0026] Further, the sanding assembly 4 comprises a plurality of first bar pins 15 arranged on the rotating shaft 2 respectively. By rotating the plurality of first bar pins 15 in the sanding barrel 1 through the rotating shaft 2, the grinding balls and the material are rotated in the sanding barrel 1 and continuously generate friction, which is beneficial to the sanding of the material.

[0027] Further, the screening assembly 5 further comprises a plurality of second bar pins 16, and the plurality of second bar pins 16 are connected with the connecting rod 9 respectively; the number of the separation laminations 7 between adjacent two second bar pins 16 is an even number greater than or equal to two.

In actual use, the second bar pin 16 is added, when the material is transported to the side of the sanding barrel 1 close to the screening assembly 5, the rotating shaft 2 synchronously drives the material and the grinding balls to continuously rotate in the sanding barrel 1 through the second bar pin 16, and the material is secondarily sanded by the grinding balls. The structure of the screening assembly 5 is simple and compact, which can screen the material and re-sand the material at the same time, thereby improving the sanding efficiency and the sanding fineness of the material.

[0029] Further, the shaft body discharging channel 6 comprises a longitudinal channel 17 and a plurality of transverse channels 18 arranged in the rotating shaft 2 respectively, the plurality of transverse channels 18 are arranged through the rotating shaft 2 along the axial direction of the rotating shaft 2 respectively, and the longitudinal channel 17 is arranged in the rotating shaft 2 along the radial direction of the rotating shaft 2 and communicates with the plurality of transverse channels 18 respectively, and the transverse channels 18 communicate with the separation cavity 10.
