Under the action of gravity, the coarse powder passes through a first drying chamber 11 and a second drying chamber 12 in sequence. The coarse powder first slides on a plurality of sliding parts 13 in the first drying chamber 11, and then slides on a plurality of sliding parts 2 14 in the second drying chamber 12. The utility model provides a combined drying section for a powder selector. The number of the first drying chamber 11 and the second drying chamber 12 can be increased or decreased (can be superimposed or decreased) according to the requirements of a given working condition, thereby flexibly realizing the increase or decrease of the range of the coarse powder, and further facilitating the washing and drying of the powder.

[0029] In one embodiment, a matching flange is installed on the first drying chamber 11 and the second drying chamber 12 .

[0030] The beneficial effects of the above technical solution are:

[0031] The arrangement of the matching flange facilitates the flexible addition and removal of the first drying chamber 11 and the second drying chamber 12 on the powder classifier body 10 .

[0032] In one embodiment, the sliding part 13 is configured as a cylindrical structure that is thin at the top and thick at the bottom. The outer diameter of the sliding part 13 in each first drying chamber 11 is gradually increased from top to bottom, and gaps are left between adjacent sliding parts 13. The outer wall of the sliding part 13 provides coarse powder sliding material.

[0033] The working principle and beneficial effects of the above technical solution are:

[0034] The coarse powder slides down from top to bottom on the outer wall of the plurality of sliding parts 13, which are cylindrical structures with thin top and thick bottom, thereby extending the sliding time and achieving the purpose of increasing the range. In addition, the washing effect of the sliding material is achieved to improve the drying effect of the coarse powder.

[0035] In one embodiment, the second sliding part 14 is configured as a cylindrical structure with a thick upper part and a thin lower part. The outer diameter of the second sliding part 14 in each second drying chamber 12 is gradually increased from bottom to top, and gaps are left between adjacent sliding parts 14. The inner wall of the sliding part 14 provides coarse powder sliding material.

[0036] The working principle and beneficial effects of the above technical solution are:

[0037] After the coarse powder slides down the outer wall of the plurality of sliding parts 13, it slides down from bottom to top on the inner wall of the plurality of sliding parts 2 14. The sliding part 2 14 is set as a cylindrical structure with a coarse top and a thin bottom, thereby further extending the sliding time and further achieving the purpose of increasing the range. In addition, the secondary washing effect of the sliding material is achieved to further improve the drying effect of the coarse powder.

[0040] The falling coarse powder falls on the dividing cone 14 and slides evenly along the surface of the dividing cone 14 .

[0041] In one embodiment, the number of the second drying chambers 12 is at least two.

[0042] In one embodiment, a tangential air inlet 16 is installed at the side end of the first drying chamber 11 .

[0043] In one embodiment, each sliding portion 13 is installed on the inner wall of the first drying chamber 11 through a supporting assembly, and the supporting assembly includes: a guide cross bar 17 and a telescopic rod 18 installed on the side end of the sliding portion 13, a vertical slide rail 19 is installed on the inner wall of the first drying chamber 11, the guide cross bar 17 is slidably installed in the vertical slide rail 19 away from the end of the sliding portion 13, and a movable rod 20 is installed at the end of the telescopic rod 18 away from the sliding portion 13, and the movable rod 20 is hinged to the inner wall of the first drying chamber 11 away from the end of the telescopic rod 18, a movable groove 21 is opened on the movable rod 20, a sliding shaft is slidably connected in the movable groove 21, the sliding shaft is installed on the pull rod 22, and the pull rod 22 is arranged to penetrate the inner wall of the first drying chamber 11 away from the sliding shaft end.

The pull rod 22 cooperates with the movable groove 21 and the sliding shaft to drive the movable rod 20 to make an upward movement on the inner wall of the first drying chamber 11. The movable rod 20 drives the telescopic rod 18 to extend, thereby driving the sliding part 13 connected to the telescopic rod 18 and the guide cross bar 17 connected to the sliding part 13 to make a lifting movement along the vertical slide rail 19, thereby achieving an increase in the vertical distance between the adjacent upper sliding parts 15.

[0046] In one embodiment, positioning holes are evenly arranged on the pull rod 22, and positioning bolts 23 adapted thereto are arranged in the positioning holes.

[0047] The working principle and beneficial effects of the above technical solution are:
