Example 1: 1-8, including at least two coaxial and suit-set sand supporting cylinders, the diameter of the sand supporting cylinders is different, the sand supporting cylinders are suit-set in turn according to the order of the diameter from small to large, the interval is left between two adjacent sand supporting cylinders, in general, the number of the sand supporting cylinders is 2-100, the number of the sand supporting cylinders can be 2, 3, 5, 10, 20, 50, 80, 100, the designer can select the number of the sand supporting cylinders according to the sand viscosity requirement; the sand supporting cylinder is characterized in that two center angle steels 5 are arranged at the center position of the innermost sand supporting cylinder, the center angle steels 5 are parallel to the central shaft of the sand supporting cylinder, two outer right-angle surface apexes (C) of the center angle steels 5 are in butt joint, and two ends of the center angle steels 5 are fixed on the connecting support 1 through welding. If too much sand slides from the upper surface, the sand slides from the central angle steel 5, then the sand continuously collides with the inclined surface of the central angle steel below the circle center and slides to the bottom in the sand drying machine barrel 4; the sand supporting cylinders comprise annular supporting frames 2 and sand supporting struts welded on the annular supporting frames, the number of the annular supporting frames 2 in each sand supporting cylinder is 1-10, connecting struts 1 are uniformly welded on the annular supporting frames 2 with different radiuses on the same plane, the annular supporting frames 2 with different radiuses are connected with each other through the connecting struts, and further the fixed installation of the annular supporting frames 2, the connecting struts 1, T-shaped steel 3 and angle steel 9 is realized, preferably, the number of the annular supporting frames 2 in each sand supporting cylinder is 2, the 2 annular supporting frames 2 are welded on the outer sides of the annular supporting frames 2 at the two ends of the sand supporting cylinders, and each connecting strut 1 is welded along the radial direction of the annular supporting frames 2; in general, the number of the sand supporting supports in each sand supporting cylinder is 3-300, namely, the number of the sand supporting supports connected between two annular supporting frames is 3-300, the number of the sand supporting supports can be 3, 5, 10, 20, 50, 100, 150, 200, 250 and 300, and a designer can set the number of the sand supporting supports according to the sand viscosity requirement; the sand supporting support is a welding body of the T-shaped steel 3 and the angle steel 9, the T-shaped steel 3 and the angle steel 9 are parallel to the central shaft of the annular support frame 2, the T-shaped steel and the angle steel are welded on the annular support frame 2 in an annular uniform array mode, the length of the T-shaped steel 3 is equal to that of the angle steel 9, the end face of the T-shaped steel and/or the angle steel is welded on the inner side of the annular support frame 2, the angle steel 9 is welded on the back of the T-shaped steel 3, namely the transverse face of the back of the T-shaped steel 3 is welded with the opening face of the angle steel 9, after the welding is finished, the outer wall of the angle steel 3 and the back of the T-shaped steel 9 form two symmetrical sand supporting faces 7, two symmetrical sand supporting grooves 8 are formed on the two sides of the T-shaped steel 9, the sand supporting faces 7 and the sand supporting grooves 8 are all used for supporting wet sand, so that the welding ensures that the sand supporting grooves 8 of the T-shaped steel 3 can receive the sand falling from a sand lifting plate within a position range of +/-45 DEG on the upper part of the circumference, and when the sand supporting is rotated to the lower side, the sand falling down meets the angle steel, the sand supporting faces can slide smoothly to the bottom.
Working principle:
the sand baking machine barrel 4 rotates, sand carried by the sand lifting plate 6 is thrown downwards in the 45-degree direction of the original horizontal line, and the left sand supporting groove 8 of the T-shaped steel below the sand lifting plate is connected with the thrown sand. When the sand amount exceeds the volume of the sand supporting groove 8 on the left side of the first T-shaped steel, the sand slides to the sand supporting groove 8 on the left side of the next T-shaped steel. In this way, the suspended supporting of the sand is completed. The scattering heat collecting frame rotates along with the sand drying machine cylinder 4 and receives the hot air for roasting. The sand edges on the sand supporting support rotate and gradually spill sand downwards, when the left position of the angle of 1-90 degrees is reached, the sand of the sand supporting groove 8 on the left side of the T-shaped steel is basically completely sprinkled on the sand supporting groove 8 on the right side of the sand supporting support below the T-shaped steel, when the lower position of the angle of 2-90 degrees is reached again, the sand on the sand supporting groove 8 on the right side of the sand supporting bracket gradually falls, and when the falling meets the angle steel 9, the sand supporting surface 7 inclined by the angle steel 9 can smoothly slide to the bottom of the inner cylinder. Then carrying out the sand carrying and sand receiving hot barbecue cycle of the lower wheel. Thus, in at least half of the circumference, the sand supporting support carries sand, is suspended in the middle of the cylinder and receives baking of hot air, so that the heat exchange efficiency is high.
In summary, when the inner cylinder rotates and sand falls from the sand lifting plate 6, the sand is supported by the plurality of sand supporting supports of the scattering heat collecting frame arranged in the sand drying machine cylinder 4, the sand supporting amount of each sand supporting support is small, and the roasted sand is suspended in the sand drying machine cylinder 4 with concentrated hot air, so that the sand is easy to roast thoroughly, and the heat absorption effect is good. If the time taken for the sand drying machine cylinder 4 to rotate for one circle is 6.6 seconds (the parameters of the sand drying machine of 9 revolutions per minute), the time for the sand to stay in suspension on the sand supporting support and be baked and dried is about 3 seconds. The inner cylinder of the sand dryer without the sand supporting support is calculated, sand falls from the top by free gravity, and the time for roasting during the descending process is about 0.3 seconds on average. The comparison result of the time of the two suspended grilled products is that: the time for the sand roasting of the sand supporting support is 10 times that of the sand roasting without the sand supporting support. Therefore, the scattering heat collecting frame of the sand drying machine has obvious sand drying heat absorbing effect after use.
