[0015] The present invention has the following beneficial effects:

[0016] (1) In the present invention, the heater is turned on to preheat the interior of the drying tower body, and the infusion pump is started. The infusion pump causes the feed pipe to suck the material into the discharge pipe. The material enters the discharge pipe and then is discharged into the round shell. The material enters the vertical pipe through the round shell. The material enters the spherical shell through the square hole set in the vertical pipe. Through the spray hopper, the material enters the spray hopper through the spherical shell and is then sprayed into the interior of the drying tower body in the form of mist. At the same time, the motor is started, the motor drives the rotating shaft to rotate, the rotating shaft drives the main gear to rotate, the main gear drives the secondary gear to rotate, and the secondary gear drives the vertical pipe to rotate. When the vertical pipe rotates, the spherical shell can be indirectly rotated, so that the range of the material when it is sprayed in the form of mist is expanded, which accelerates the drying efficiency of the device for the mist material. At the same time, when the main gear rotates, it drives the arc fan to rotate. When the arc fan rotates, the hot air scattered around the interior of the drying tower body is gathered near the arc fan, so that the mist material can be dried just after it is converted, further enhancing the drying efficiency of the device.

[0017] (2) In the present invention, when the rotating shaft rotates, the rotating shaft drives the cross plate to rotate, the cross plate drives the concave block to rotate, the concave block drives the rotating rod to rotate, the rotating rod drives the sleeve block to rotate, the sleeve block drives the cross bar to rotate, the cross bar drives the brush roller to rotate, and the brush roller contacts the inner side of the heating shell during the rotation process, so that the brush roller rotates around the cross bar, so that the brush roller cleans the dry material adhered to the inner side of the heating shell, preventing the material from adhering to the inner wall of the heating shell all the time, thereby increasing the material yield, and at the same time the rotating rod drives The moving main triangular block rotates inside the auxiliary box. When the main triangular block comes into contact with the secondary triangular block, the main triangular block swings slightly due to the reaction force brought by the blocking of the secondary triangular block. The main triangular block drives the rotating rod to swing in the opposite direction, and the rotating rod drives the sleeve block to swing in the opposite direction. During the reverse swinging of the sleeve block, the arc spring is set to enable the sleeve block to swing left and right, thereby indirectly enabling the brush roller to swing slightly. During the swinging of the brush roller, the powdered material adhering to the bristles of the brush roller falls off, further increasing the material output.

[0018] (3) In the present invention, when the main triangular block is blocked by the secondary triangular block, the two suddenly stop contacting, and the reaction force generated causes the main triangular block to squeeze the airbag. The airbag is squeezed suddenly because the end of the cone head tube close to the spherical filter is conical. When the internal airflow moves to the cone through the cone head tube, the force of the airflow spraying will be increased again. The airflow passes through the spherical filter at the cone head tube and enters the interior of the drying tower body. The airflow can spray the mist material sprayed at the spray hopper again, further improving the mist degree of the mist material and indirectly improving the drying efficiency of the device.

[0019] (4) In the present invention, when the interior of the drying tower body is continuously heated, the internal air pressure will increase. When the air pressure rises to a certain level, the air pressure will squeeze the sliding rod through the pressure tube, and the sliding rod will drive the arc plate to move. At the same time, the return spring is set, so that the arc plate can move back and forth inside the arc box, so that the cold air cooled by the condensation box inside the arc box is mixed with the water flow inside the cooling box, so as to cool the outer wall of the drying tower body, indirectly reducing the air pressure inside the drying tower body, and in the process of reciprocating movement of the arc plate, the water flow passes through the cooling box and enters the interior of the arc tube, so that the water flow circulates, further enhancing the cooling effect of the drying tower body, improving the service life of the drying tower body, and enabling the drying tower body to produce powdered materials more stably.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] An annular groove 7715 is provided on one side of the outer wall of the auxiliary box 778, one end of the rotating rod 773 passes through the concave block 772 and is slidably connected to the outer wall of the annular groove 7715, and a main triangular block 779 is sleeved and fixedly connected on the outer wall of the end of the rotating rod 773 away from the sleeve block 774.

One end of the conical head tube 7712 passes through the auxiliary box 778 and extends to the interior of the drying tower body 1. The end of the conical head tube 7712 away from the airbag 7710 is connected to a spherical filter screen 7713.

The rotating rod 773 is sleeved on the outer wall of the main triangular block 779 and is fixedly connected with a plurality of annular baffles 7714. The purpose of this arrangement is to prevent powdered materials from entering the interior of the auxiliary box 778. One side of the annular baffle 7714 contacts one side of the outer wall of the auxiliary box 778.

[0042] The heater 766 is turned on to preheat the interior of the drying tower body 1, and the infusion pump 71 is started. The infusion pump 71 causes the feed pipe 72 to suck the material into the discharge pipe 73. The material enters the discharge pipe 73 and then is discharged into the round shell 74. The material enters the vertical pipe 761 through the round shell 74. The material enters the spherical shell 763 through the square hole 762 set in the vertical pipe 761.

When the arc fan 754 rotates, the hot air scattered around the inside of the drying tower body 1 will be gathered near the arc fan 754, so that the mist material can be dried just after it is converted, further enhancing the drying efficiency of the device.

[0043] When the rotating shaft 752 rotates, the rotating shaft 752 drives the cross plate 771 to rotate, the cross plate 771 drives the concave block 772 to rotate, the concave block 772 drives the rotating rod 773 to rotate, the rotating rod 773 drives the sleeve block 774 to rotate, the sleeve block 774 drives the cross bar 775 to rotate, the cross bar 775 drives the brush roller 776 to rotate, and the brush roller 776 contacts the inner side of the heating shell 765 during the rotation process, so that the brush roller 776 rotates around the cross bar 775, so that the brush roller 776 cleans the dry material adhered to the inner side of the heating shell 765, prevents the material from adhering to the inner wall of the heating shell 765, and improves the material yield. 3 drives the main triangular block 779 to rotate inside the auxiliary box 778. When the main triangular block 779 contacts the secondary triangular block 7711, the main triangular block 779 is slightly swung by the reaction force brought by the blocking of the secondary triangular block 7711. The main triangular block 779 drives the rotating rod 773 to swing in the opposite direction. The rotating rod 773 drives the sleeve block 774 to swing in the opposite direction.

[0044] In Example 2, a cooling assembly 78 is provided on the outer wall of the drying tower body 1. The cooling assembly 78 includes a plurality of arc boxes 781 fixedly connected around the top of the outer wall of the drying tower body 1. One side of the arc box 781 is connected to a pressure pipe 782. One end of the pressure pipe 782 passes through the arc box 781 and extends to the interior of the drying tower body 1. A sliding rod 783 is sleeved on the inner wall of the pressure pipe 782 and slidably connected. Condensation boxes 784 are fixedly connected on both sides of the bottom of the inner wall of the arc box 781. The purpose of this arrangement is to be able to emit cold air.

[0045] One end of the sliding rod 783 is fixedly connected to an arc plate 785.

The outer wall of the arc plate 785 is sleeved and slidably connected to the inside of the arc box 781. The side of the arc plate 785 away from the sliding rod 783 is fixedly connected to a return spring 786. The purpose of this arrangement is to be able to reset. One end of the return spring 786 is fixedly connected to one side of the inner wall of the arc box 781. The bottom center of the arc box 781 is connected to a cooling box 787. The bottom of the cooling box 787 is fixedly connected to the top of the ring 2. A number of arc tubes 788 are connected between the two cooling boxes 787. One side of the outer wall of the arc tube 788 is in contact with the outer wall of the drying tower body 1.

[0046] During use, when the main triangular block 779 is blocked by the secondary triangular block 7711, the two suddenly stop contacting, and the reaction force generated causes the main triangular block 779 to squeeze the airbag 7710. The airbag 7710 is squeezed suddenly because the end of the cone head tube 7712 close to the spherical filter 7713 is conical. When the internal airflow moves to the cone through the cone head tube 7712, the force of the airflow spraying is increased again, and the airflow enters the interior of the drying tower body 1 through the spherical filter 7713 at the cone head tube 7712. The airflow can spray the mist material sprayed at the spray bucket 764 again, further improving the mist degree of the mist material and improving the drying efficiency of the device.

[0047] When the interior of the drying tower body 1 is continuously heated, the internal air pressure will increase. When the air pressure rises to a certain level, the air pressure will squeeze the sliding rod 783 through the pressure tube 782, and the sliding rod 783 will drive the arc plate 785 to move. At the same time, the return spring 786 is set, so that the arc plate 785 can move back and forth inside the arc box 781, so that the cold air cooled by the condensation box 784 inside the arc box 781 is mixed with the water flow inside the cooling box 787, so as to cool the outer wall of the drying tower body 1, indirectly reducing the air pressure inside the drying tower body 1, and in the process of the reciprocating movement of the arc plate 785, the water flow passes through the cooling box 787 and enters the interior of the arc tube 788, so that the water flow circulates, further enhancing the cooling effect of the drying tower body 1, and improving the working life of the drying tower body 1, so that the drying tower body 1 can produce powdered materials more stably.
