[0032] The sliding material assembly 12 is installed in the powder selecting machine body 10 and is located below the powder selecting assembly 11. The coarse powder falls on the top of the sliding material assembly 12 and slides down from the surface of the sliding material assembly 12 from top to bottom.

[0033] The lower air supply port 13 is installed at the bottom end of the powder selector body 10 and supplies hot air to the sliding material assembly 12 from bottom to top.

[0034] The working principle and beneficial effects of the above technical solution are:

[0035] The utility model discloses a sliding material dripping device, in which the powder selection component 11 in the powder selection machine body 10 realizes separation of coarse powder and fine powder with different particle sizes, the fine powder comes out from the top, the coarse powder falls down, the falling coarse powder falls on the sliding material component 12, and falls step by step on the sliding material component 12, at this time, the hot air sent by the lower air supply port 13 dries the coarse powder falling step by step on the sliding material component 12. The utility model provides a sliding material dripping device, in the process of the coarse powder falling step by step on the sliding material component 12, the falling speed of the sliding material is reduced, thereby prolonging the heat exchange time with the hot air sent from the lower air supply port 13, and the coarse powder falls, and the wind blows upward, which has the effect of washing the coarse powder.

[0036] In one embodiment, the slider assembly 12 includes:

[0037] A dividing cone 14, which is located below the powder selection assembly 11, and the coarse powder falls on the dividing cone 14;

[0038] An upper sliding part 15, multiple upper sliding parts 15 are longitudinally distributed below the material distribution cone 14, and the upper sliding part 15 is a cylindrical structure with a thin top and a thick bottom. The diameters of the multiple upper sliding parts 15 are arranged to increase step by step from top to bottom, and gaps for air delivery are left between adjacent upper sliding parts 15. The coarse powder falls on the material distribution cone 14 and slides on the outer wall of the upper sliding part 15. The wind is delivered into each upper sliding part 15 from bottom to top in sequence;

[0039] The wind dispersion cone 16 is located below the upper sliding material portion 15 and is disposed close to the lower air supply port 13 .

[0040] The working principle and beneficial effects of the above technical solution are:

[0041] The falling coarse powder falls on the dividing cone 14 and slides evenly along the surface of the dividing cone 14. The coarse powder slides from top to bottom on the outer walls of multiple upper sliding parts 15. The upper sliding parts 15 are cylindrical structures with thin tops and thick bottoms, thereby extending the sliding time of the coarse powder. The lower air supply port 13 vertically inlets air to the bottom of the powder selector body 10. Under the action of the air dispersion cone 16, the hot air is scattered and passes through the inner walls of each upper sliding part 15 from bottom to top. The hot air is blown out from the gaps between adjacent upper sliding parts 15, thereby achieving a scrubbing effect on the coarse powder and improving the drying effect of the coarse powder.

[0042] In one embodiment, the sliding material assembly 12 further includes:

[0043] A lower sliding portion 17, multiple lower sliding portions 17 are longitudinally distributed between the upper sliding portion 15 and the wind dispersion cone 16, the lower sliding portion 17 is a cylindrical structure that is thick at the top and thin at the bottom, the diameters of the multiple lower sliding portions 17 are arranged to increase step by step from bottom to top, and gaps for air to be sent in are left between adjacent lower sliding portions 17, the diameter of the lower sliding portion 17 close to the upper sliding portion 15 is larger than the diameter of the upper sliding portion 15, the coarse powder slides on the inner wall of the lower sliding portion 17, and the wind is sent into each lower sliding portion 17 from bottom to top in turn.

[0044] The working principle and beneficial effects of the above technical solution are:

[0045] A lower sliding part 17 is added between the upper sliding part 15 and the air dispersion cone 16. After the coarse powder slides down on the outer walls of the multiple upper sliding parts 15 from top to bottom, it slides down on the inner walls of the multiple lower sliding parts 17 from bottom to top, until it falls on the air dispersion cone 16 and is concentrated at the bottom end of the powder classifier body 10. The lower air supply port 13 vertically inlets air to the bottom end of the powder classifier body 10. Under the action of the air dispersion cone 16, the hot air is scattered and passes through the outer walls of each lower sliding part 17 from bottom to top. The hot air is blown in from the gaps between the adjacent lower sliding parts 17, thereby achieving a secondary washing effect on the coarse powder, and further improving the drying effect of the coarse powder.

[0046] In one embodiment, the upper sliding part 15 is connected to the inner wall of the powder classifier body 10 through a side support rod assembly 1, and the number of the upper sliding parts 15 is at least 2.

A limiting slide groove 22 is installed on the flip rod 21, and a limiting column is slidably installed in the limiting slide groove 22. The pull rod 23 extends into the powder classifier body 10 from the side end of the powder classifier body 10, and the limiting column is installed on the pull rod 23.

[0051] The working principle and beneficial effects of the above technical solution are:

[0052] When it is necessary to adjust the vertical distance between adjacent upper sliding parts 15, so as to achieve the gap adjustment of adjacent upper sliding parts 15, the pull rod 23 is manually pulled, and the pull rod 23 drives the flip rod 21 to make an upward movement on the inner wall of the powder selection machine body 10 through the cooperation of the limiting slide groove 22 and the limiting column. The flip rod 21 drives the telescopic rod 19 to extend, thereby driving the upper sliding part 15 connected to the telescopic rod 19 and the cross bar 18 connected to the upper sliding part 15 to make a lifting movement along the vertical groove 20, thereby achieving the increase of the vertical distance between adjacent upper sliding parts 15.

[0054] In one embodiment, a handle 24 is installed at the end of the pull rod 23 away from the limiting column, and a plurality of limiting holes are installed at equal intervals on the pull rod 23. The limiting bolts 25 are passed through the limiting holes and abut against the outer wall of the powder classifier body 10.
