The air inlet pipe 4 is connected with a nut 42 through threads on one side of the discharge hopper 13, which is far away from the air outlet pipe 41, when the nut 42 is inconsistent with the side wall of the discharge hopper 13, the air outlet pipe 41 is inconsistent with the inner wall of the discharge hopper 13, one end, which is far away from the air outlet pipe 41, of the air inlet pipe 4 is communicated with a third pipeline 47, and one end, which is far away from the air inlet pipe 4, of the third pipeline 47 is connected to the air heater 19 (as shown.
Referring to fig. 2 and 4, the dried nano calcium carbonate enters the discharging hopper 13, and at this time, the hot air blower 19 (as shown in fig. 1) delivers hot air to the air inlet pipe 4 through the third pipeline 47. The hot air then enters the air outlet pipe 41 from the air inlet pipe 4 and is discharged between the rubber air cushion 44 and the discharge hopper 13 from the air outlet hole 43. Rubber air cushion 44 is made by the rubber material, rubber self is softer and produces deformation easily, hot-blast with rubber air cushion 44 jack-up, it overflows between rubber air cushion 44 and the play hopper 13 to make rubber air cushion 44 laminate with the lateral wall of play hopper 13 once more, the continuous conveying gas of air heater 19 (as figure 1), make rubber air cushion 44 discontinuous with the lateral wall laminating of play hopper 13, rubber air cushion 44 has realized the mesh of slapping out hopper 13 lateral wall, make play hopper 13 produce vibrations, in order to accelerate the speed that nanometer calcium carbonate slides down in going out hopper 13, make nanometer calcium carbonate discharge out hopper 13 fast. And hot air enters the nano calcium carbonate, so that the nano calcium carbonate becomes loose, the phenomenon that the nano calcium carbonate is accumulated to block the discharge hopper 13 is reduced, meanwhile, the hot air can further heat the nano calcium carbonate, the effect of drying the nano calcium carbonate is achieved, and the drying fullness of the nano calcium carbonate is improved.
Referring to fig. 4, the cover of intake pipe 4 is equipped with sealed the pad 45 between outlet duct 41 and play hopper 13 lateral wall, and sealed pad 45 is made by the rubber material, and rubber self is softer and have elasticity and produce deformation easily to the rubber pad can be filled up the gap between outlet duct 41 and the play hopper 13 lateral wall, and then increases the leakproofness between outlet duct 41 and the play hopper 13, with the possibility that gas leakage appears in the gap that reduces outlet duct 41 and play hopper 13.
Referring to fig. 1 and 2, two exhaust pipes 5 are symmetrically arranged on the top wall of the box body 1 along the peripheral direction, both the two exhaust pipes 5 are communicated with the box body 1, a filter screen 51 is fixedly connected to one side of each exhaust pipe 5 close to the box body 1, and an exhaust fan 52 is arranged on one side of each exhaust pipe 5 far away from the filter screen 51. The operator starts the exhaust fan 52, and the exhaust fan 52 can accelerate the flow rate of the air in the exhaust pipe 5, and at this moment, the exhaust fan 52 extracts the water vapor generated by the drying of the nano calcium carbonate out of the box body 1. Simultaneously, the nano calcium carbonate contained in the gas is filtered by the filter screen 51, so that water vapor is rapidly discharged from the box body 1, the water content of the gas in the box body 1 is reduced, the drying degree of the nano calcium carbonate is improved, and the quality of the nano calcium carbonate is further improved.
Referring to fig. 2, the outer side wall of the box body 1 is sleeved with a heat preservation layer 6, the heat preservation layer 6 is made of rubber and plastic sponge materials, and the heat conductivity coefficient of the rubber and plastic sponge is low, so that the heat preservation layer 6 plays a heat preservation role in the box body 1, heat dissipation in the box body 1 is further reduced, and the degree of filling for drying the nano calcium carbonate is improved.
The implementation principle of the embodiment is as follows: the operator pours the nano calcium carbonate to be dried into the hopper 12 and the nano calcium carbonate slides into the feeding pipe 11 along the inclined direction of the hopper 12. Then the operator starts the motor 2 and the hot air blower 19 simultaneously, the motor 2 drives the hot air duct 15 to rotate through the second bevel gear 22 and the first bevel gear 21, and the hot air duct 15 drives the hollow ball 16, the flow guide disc 31, the air delivery pipe 3 and the rotating disc 36 to rotate. When the hot air pipe 15 rotates, the hot air pipe 15 drives the stirring rod 151 to rotate together, and the stirring rod 151 stirs the nano calcium carbonate in the feeding pipe 11, so that the nano calcium carbonate is uniformly distributed in the feeding pipe 11. Then the nano calcium carbonate falls down uniformly through the gap between the hollow ball 16 and the drainage cover 14, and the hollow ball 16 rotates to further disperse the nano calcium carbonate uniformly. Meanwhile, hot air is blown out through the air outlet 161 and blows away the nano calcium carbonate in the box body 1, and the nano calcium carbonate is uniformly dispersed in the box body 1, so that the hot air heats the nano calcium carbonate to achieve the effect of drying the nano calcium carbonate.
The dried nano calcium carbonate falls onto the diversion plate 31, the diversion plate 31 rotates to throw the nano calcium carbonate out, the nano calcium carbonate falls onto the diversion plate 32 along the side wall of the box body 1, and then the nano calcium carbonate uniformly slides downwards along the inclination direction of the diversion plate 32. When the nano calcium carbonate slides out of the guide plate 32, the hot air blower 19 conveys hot air into the air collecting pipe 33 through the second pipeline 35, the hot air is blown out of the nozzle 34, the nano calcium carbonate is uniformly blown out of the box body 1 again, and the hot air heats the nano calcium carbonate again, so that the effect of drying the nano calcium carbonate is achieved, and the degree of fullness of the nano calcium carbonate is improved.
The nano calcium carbonate after the secondary drying falls onto the rotating disc 36, hot air sequentially passes through the first pipeline 18, the adapter 17, the hot air pipe 15, the hollow ball 16 and the air conveying pipe 3 to enter the rotating disc 36, and the rotating disc 36 is heated, so that the rotating disc 36 heats the nano calcium carbonate, and the nano calcium carbonate is further heated and dried. And the rotating disc 36 rotates to throw away the nano calcium carbonate, and the nano calcium carbonate falls into the discharging hopper 13 through the gap between the box body 1 and the rotating disc 36. Meanwhile, hot air is blown out from the air outlet 37 to blow the nano calcium carbonate to be dispersed to the periphery, so that the falling speed of the nano calcium carbonate is accelerated.
After nanometer calcium carbonate enters into out hopper 13, nanometer calcium carbonate discharges from going out hopper 13, air heater 19 carries the hot-blast intake pipe 4 through third pipeline 47 this moment, then intake pipe 4 discharges from exhaust hole 43 through outlet duct 41, hot-blast air enters into between rubber air cushion 44 and the play hopper 13 and with rubber air cushion 44 jack-up, gas spills over with the back, rubber air cushion 44 laminates with going out hopper 13 once more, make rubber air cushion 44 pat out hopper 13, go out hopper 13 and produce vibrations, in order to accelerate nanometer calcium carbonate exhaust speed, the hot-blast air that spills over simultaneously further heats the drying to nanometer calcium carbonate.
The operator starts the exhaust fan 52, and the exhaust fan 52 extracts the vapor generated by the drying of the nano calcium carbonate, so as to improve the degree of sufficiency of the drying of the nano calcium carbonate. Meanwhile, the heat preservation layer 6 is used for preserving heat of the box body 1 so as to reduce the dissipation of heat inside the box body 1 and further improve the drying fullness of the nano calcium carbonate.
