In addition, the number of the first rake arm 23 and the second rake arm 25 is different from the number of the inner pushing rake teeth 24 and the outer expanding rake teeth 26, so that the retention time of wet materials on each charging tray can be adjusted. Therefore, the utility model discloses a low temperature whirl carousel material mummification machine's cloth wind structure can uninterrupted operation, improves the mummification efficiency of system.
The working principle of the embodiment is as follows:
The utility model discloses a low temperature whirl carousel material mummification machine's cloth wind structure is when using, and mummification room 1 opens driving motor and drives center pin 27 and rotate through the unsettled setting of support, installs big charging tray 7 and the synchronous rotation of little charging tray 9 on center pin 27. Wet materials are uniformly and continuously added to the large material tray 7 on the uppermost layer of the drying chamber 1 through the wet material inlet 29, the internal pushing rake teeth 24 on the first rake arm 23 at the corresponding position of the large material tray 7 continuously disperse, strickle, turn, shear and crush the wet mud falling on the large material tray 7, the wet mud is uniformly heated, and meanwhile, the wet materials are pushed inwards to move downwards towards the through hole 31. The wet material that assembles at through-hole 31 department falls into the small charging tray 9 middle part of next floor through-hole 31, and the outer rake teeth 26 that expand on the second rake arm 25 of small charging tray 9 corresponding position outwards transfers wet material, when wet material when crossing the outer fringe of small charging tray 9, falls into again on the big charging tray 7 of next floor. By parity of reasoning, the wet materials are gradually transferred to the bottom layer material tray layer by layer, and are simultaneously dried by hot air in the drying chamber 1 in a rotational flow manner, and the dried materials are output through the dry material outlet 30.
In addition to the flow of the above materials, the present invention also includes the air flow circulation between the drying chamber 1 and the heat pump 2.

because the center of the large tray 7 is provided with the through hole 31 with larger diameter and the distance between the through hole and the inner wall of the drying chamber 1 is smaller, and the inner edge of the small tray 9 is directly fixed on the central shaft 27, the working gas can not circulate and can only circulate greatly between the outer edge of the small tray 9 and the inner wall of the drying chamber 1. Therefore, the working gas which is blown by wet materials at the lower layer can only flow into the large material tray 7 through the through hole 31 of the large material tray 7 and flow into the small material tray 9 through the gap between the small material tray 9 and the inner wall of the drying chamber 1, so that the upward working gas rotational flow is formed in the drying chamber 1.
Therefore, the working gas carries the water vapor, the water vapor is convolutely staggered layer by layer from bottom to top and is finally discharged from the air outlet 18 of the drying chamber, and the heat of the dry and hot working gas is fully utilized step by step to take away the water vapor in the wet materials on each layer of material disc, so that the problem that the drying effect of the box type mesh belt machine is not ideal is solved.
