The elastic cloth 4 can capture the quartz sand and make it slide smoothly, effectively increasing the cleanliness and smoothness of the discharge hopper 84. The rotating plate 41 can effectively reduce the quartz sand from adhering to the surface of the elastic cloth 4 due to static electricity, effectively reducing the decrease in discharge efficiency, and effectively making the quartz sand attached to the surface of the elastic cloth 4 fall off, effectively increasing the popularity and smoothness of the quartz sand discharge.
[0028] like Figure 5 As shown, a plurality of groups of grooves 5 are provided in the middle of the rotating plate 41; the plurality of groups of grooves 5 are equidistantly distributed on the side wall of the rotating plate 41; the plurality of groups of grooves 5 are rotatably connected in the middle of the plurality of groups of grooves 5; during operation, when the rotating plate 41 contacts and rotates with the elastic cloth 4, the plurality of groups of pulleys 51 contact the surface of the elastic cloth 4, and when the pulley 51 contacts and moves with the surface of the elastic cloth 4, the grooves 5 rotate at the same time, and the pulley 51 can effectively reduce the friction generated by the contact between the rotating plate 41 and the elastic cloth 4, and can effectively make the rotating plate 41 rotate more smoothly, and effectively reduce the wear on the surface of the elastic cloth 4 caused by friction, and the pulley 51 can effectively make the elastic cloth 4 evenly stressed, and can effectively reduce the situation of excessive stretching of the elastic cloth 4, and effectively increase the service life of the elastic cloth 4 for a long time.
[0029] like Figure 1As shown, the middle part of the U-shaped tube 83 is fixedly connected with thermal insulation cotton 6; the thermal insulation cotton 6 is fixedly connected to the outside of the U-shaped tube 83; during operation, when hot air enters the interior of the heating pipe through the U-shaped tube 83, the heat of the U-shaped tube 83 is stored inside the thermal insulation cotton 6 through the thermal insulation cotton 6, and the thermal insulation cotton 6 can effectively reduce the transfer and loss of heat energy of the U-shaped tube 83, and can effectively retain the heat inside the U-shaped tube 83, effectively reducing the heat loss, and the thermal insulation performance of the thermal insulation cotton 6 can effectively reduce the thermal stress of the U-shaped tube 83 caused by temperature changes, effectively reduce the problem of thermal expansion and contraction of the U-shaped tube 83, effectively reduce the condensation of moisture in the air into water droplets when the surface temperature of the U-shaped tube 83 is too low, and effectively reduce the damage and pollution of the U-shaped tube 83 caused by temperature difference and condensed water.
[0030] During operation, the hot air flow is discharged from the end of the air inlet pipe 85 so that the hot air enters the heating pipe arranged inside the drying box 8 through the air inlet 80, so that the surface of the heating pipe generates heat, and the hot air is discharged through the air outlet 81, enters the heating pipes inside other drying boxes 8 through the U-shaped pipe 83, and is finally discharged through the air outlet pipe 82.
