The multi-bending sand-lifting plate I and the multi-bending sand-lifting plate II adopted in the invention are disclosed in the patent number 201711292674.3, and the disclosed multi-bending sand-lifting plate can play a better role by combining the kiln head of the invention, so that the sand drying work is smoother. Further explanation in connection with the present invention: the sand flow can be spirally carried to the right above the kiln head cylinder by the sand lifting plate, and the main reasons are as follows: 1. sand blocking function of the bending surface of the sand lifting plate in the spiral row of the sand lifting plate; 2. the centrifugal force of kiln head rotation acts; 3. the tangent line of the spiral line of the small spiral plate spiral line contacted with the kiln head cylinder and the included angle with the horizontal plane are variables when the dryer rotates. The included angle is 0 degrees when the dryer rotates and is positioned at the lowest point of the kiln head cylinder, the included angle is gradually increased when the sand dryer rotates at the point of 0-90 degrees, the included angle is maximum and is equal to the spiral angle of the point when the sand dryer reaches 90 degrees, the included angle is gradually decreased when the kiln head cylinder rotates at the point of 90-180 degrees, the larger the included angle is, the driving force of sand flowing towards the outlet direction is larger, and the acceleration obtained by sand flow is also larger; 4. the acceleration of the forward flow is much less than the acceleration of gravity as the sand rotates within the kiln head barrel. Moreover, the humidity of the sand increases, and the acceleration of the sand flow sliding in the outlet direction is further reduced. Just as the flow of sand is for the 4 reasons above, the movement of the flow of sand within the kiln head drum is complex and continuous sliding and falling in the direction of the dryer. When the sand flows onto the sand lifting plate closest to the kiln head port, the sand flow will follow the face of the sand lifting plate and will start to fall down when the kiln head rotates to the three-eighths position point. The subsequent drop process is similar to the drop process of sand flow in a spiral row of the sand lifting plate. However, the position of the drop point is not in the kiln head barrel any more, but in the inner barrel of the sand drying machine with the diameter smaller than that of the kiln head barrel. That is, during this stage of movement, the sand falls into the dryer drum from a lower position of the kiln head drum, with a step. The sand flow in the kiln head cylinder not only moves towards the outlet direction, but also falls off during sand lifting, and the sand flow can absorb heat on the sand lifting plate and can absorb the hot air during the falling off of the sand lifting.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present invention.
