[0027] The feeding assembly includes a feeding hopper 4, a support neck block 5 is provided at the lower end of the feeding hopper 4, and a triangular inclined platform 6 is provided at the bottom of the support neck block 5. The triangular inclined platform 6 forms an inclined feeding channel 7 between the feeding hopper 4 and the screen cylinder 2 by cooperating with the inner wall of the support neck block 5.

[0028] A hot air pipe docking cavity 8 is provided inside the support neck block 5 at the upper end of the triangular inclined platform 6, and a hot air pipe assembly is docked inside the hot air pipe docking cavity 8.

[0029] The hot air duct assembly includes a head section duct 9 inserted into the hot air duct docking cavity 8. The head section duct 9 is connected to a corrugated hose 11 via a rubber plug 10. The corrugated hose 11 is connected to a hot air blower.

[0030] A filter mesh 12 is provided at the bottom of the transmission pipe 3.

[0034] Working principle:

[0035] The coated sand material to be processed enters from the feed hopper and is filtered and screened by vibration as it descends along the spiral descending transmission pipe. Smaller sand particles or impurities fall from the filter mesh at the bottom of the transmission pipe into the bottom collection box below, while larger sand particles enter the collection bag in the collection bag placement chamber through the output pipe at the end of the transmission pipe.

[0036] During the sand transport process, hot air from an external hot air blower is blown into the upper initial section of the transport pipe from the first section of the air duct. The hot air preheats the sand along the inside of the transport pipe, and at the same time, it can further enhance the turbulence of the sand in the transport pipe, thereby improving the filtration and screening effect.

[0037] The downward speed of the sand can be adjusted by preset adjustment of the descent amplitude (inclination) of the spiral structure of the transmission pipe and adjustment of the hot air speed.
