DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1 and Figure 2 A fertilizer drying device for fertilizer production comprises a vertical drying cylinder 1 equipped with supporting legs 2, a vertical drying chamber 3 arranged inside the vertical drying cylinder 1, a discharge channel 4 arranged at the bottom end of the vertical drying chamber 3 and having an open bottom, a blocking plate 6 installed at the bottom end of the discharge channel 4, a pipe mounting hole 5 arranged on the circumferential surface of the vertical drying cylinder 1, a feeding port 7 for feeding raw materials into the vertical drying chamber 3, and a driving motor 9 fixedly installed on the top of the vertical drying cylinder 1 through a motor mounting shell 8. Fertilizer is fed into the vertical drying chamber 3 through the feeding port 7, and the driving motor 9 and the blower dryer are turned on. When the fertilizer is dried, the driving motor 9 and the blower dryer are turned off, and the blocking plate 6 is opened to collect the dried fertilizer below.

[0027] In order to achieve the function of circulating fertilizer particles, please refer to Figure 2 and Figure 3 , it is necessary to set up a material driving mechanism 11, which is provided with a spiral blade 114 located inside the vertical drying chamber 3 and capable of rotating with the rotor 10 of the driving motor 9. When rotating, the spiral blade 114 can make the surrounding materials produce an axial flow effect. The rotation of the connecting shaft 112 will drive the conical rotating disk 111 and the spiral blade 114 to rotate. By controlling the rotation direction of the rotor 10, the rotation direction of the spiral blade 114 can be controlled, so that the surrounding fertilizer particles will move upward. When the upward moving fertilizer particles touch the rotating conical rotating disk 111, the fertilizer particles will diffuse outward. Combined with the gravity of the fertilizer particles themselves, they will cause themselves to circulate and scatter, thereby expanding the gap between the fertilizer particles, so that the high-temperature gas has sufficient movement gap to improve the drying effect.

[0028] For the specific structure of the material driving mechanism 11, please refer to Figure 3 , including a conical rotating disk 111 located inside the vertical drying chamber 3, the upper surface and the lower surface of the conical rotating disk 111 are both conical structures, and the edge thickness is lower than the thickness of the central structure, the top of the conical rotating disk 111 is fixedly installed with a connecting shaft 112, the bottom of the conical rotating disk 111 is provided with a rotating rod 113 which is an integral structure with it and extends downward, the rod body of the rotating rod 113 is provided with a spiral blade 114 which is an integral structure with it, the axis center lines of the conical rotating disk 111, the connecting shaft 112 and the rotating rod 113 are on the same axial line, and the straight line is collinear with the axis center line of the vertical drying chamber 3.

[0029] To increase the gas flow range, see Figure 1 , Figure 2 and Figure 4 , it is necessary to set up a gas guiding mechanism 12, inside which is provided a hollow cylinder 121 located inside the vertical drying chamber 3 and outside the spiral blade 114, and a gas discharge hole 126 arranged inside the hollow cylinder 121 and capable of discharging gas to the surroundings. Before work, it is necessary to connect the air inlet port of each gas flow hole 125 with the air outlet of a blower dryer, and the high-temperature gas will enter the interior of the annular gas flow chamber 123 along the gas flow hole 125, and finally diffuse to the surroundings along each gas discharge hole 126, thereby increasing the gas flow range.

[0030] For the specific structure of the gas guiding mechanism 12, please refer to Figure 4, comprising a hollow cylinder 121 located inside the vertical drying chamber 3, a material conveying chamber 122 with both ends being open is arranged at the center of the hollow cylinder 121, the spiral blade 114 is placed inside the material conveying chamber 122, a closed annular gas flow chamber 123 is arranged inside the hollow cylinder 121 at the periphery of the material conveying chamber 122, a plurality of horizontal channels 124 which are integrally formed with the hollow cylinder 121 and pass through the pipeline mounting hole 5 are arranged on the circumferential surface of the hollow cylinder 121, and the horizontal channels 124 are arranged on the circumferential surface of the hollow cylinder 121.

There is a gap between the bottom end of the hollow cylinder 121 and the nearest wall of the vertical drying chamber 3, and the gap is sufficient to allow the fertilizer particles to flow. There is a gap between the top end of the hollow cylinder 121 and the bottom end of the conical rotating disk 111, and the gap is sufficient to allow the fertilizer particles to flow.

[0031] In order to prevent the torque resistance from being too large and causing the drive motor 9 to be overloaded, please refer to Figure 2 , Figure 5 and Figure 6 , it is necessary to set up a combined linkage mechanism 13, which is internally provided with a hollow disk body 131 that rotates with the rotor 10, an inner rotating column 1310 that can drive the connecting shaft 112 to rotate, and an arc-shaped contact plate 139 that can link the hollow disk body 131 and the inner rotating column 1310 by friction. When the torque force is greater than the maximum static friction force formed by the coil spring 138, the inner rotating column 1310 and the arc-shaped contact plate 139 will cause relative rotation, thereby preventing the occurrence of overload of the drive motor 9 caused by excessive torque resistance.

[0032] For the specific structure of the combined linkage mechanism 13, please refer to Figure 5 and Figure 6, including a hollow disk body 131 and an inner rotating column 1310, the upper end surface of the hollow disk body 131 is provided with a No. 1 shaft body fixing groove 132 for fixing and installing the rotor 10, the center of the hollow disk body 131 is provided with a columnar component installation cavity 133, the bottom center of the hollow disk body 131 is provided with a shaft body installation hole 134, the shaft body of the No. 1 rotating shaft 12 is installed inside the shaft body installation hole 134 through a bearing, the center of the columnar component installation cavity 133 is provided with an inner rotating column 1310, the bottom center of the inner rotating column 1310 is provided with a No. 2 shaft body fixing groove 1311 for fixing and installing the connecting shaft 112, the hollow disk body 131 is provided with a plurality of annular array-type horizontal component active cavities 135 on the periphery of the columnar component installation cavity 133, and the circumferential side surfaces of the horizontal component active cavity 135 and the columnar component installation cavity 133 The hollow disk body 131 is connected through the shaft body through hole 136, and an inner movable plate 137 capable of axial movement along the cylindrical component mounting cavity 133 is arranged inside the cylindrical component mounting cavity 133, and a coil spring 138 is arranged at one end of the inner movable plate 137, and a connecting shaft body passing through the shaft body through hole 136 is fixedly installed on the other end of the inner movable plate 137, and an arc-shaped contact plate 139 that abuts against the circumferential surface of the inner rotating column 1310 is fixedly installed on one end of the connecting shaft body located inside the cylindrical component mounting cavity 133, one end of the coil spring 138 abuts against one end surface of the inner movable plate 137, and the other end abuts against one end surface of the transverse component active cavity 135, and the coil spring 138 is in a compressed state, and the structural radius of the inner concave surface of the arc-shaped contact plate 139 matches the structural radius of the inner rotating column 1310.

[0033] When in use, the air inlet port of each gas flow hole 125 is connected to the air outlet of a blower dryer, and the fertilizer is put into the vertical drying chamber 3 through the feeding port 7. The driving motor 9 and the blower dryer are turned on. The rotation of the connecting shaft 112 will drive the conical rotating disk 111 and the spiral blade 114 to rotate. By controlling the rotation direction of the rotor 10, the rotation direction of the spiral blade 114 can be controlled, so that the surrounding fertilizer particles will move upward. When the upward moving fertilizer particles touch the rotating conical rotating disk 111, the fertilizer particles will diffuse outward. With the gravity of the fertilizer particles themselves, they will circulate and scatter, thereby expanding the gaps between the fertilizer particles. The high-temperature gas will enter the interior of the annular gas flow chamber 123 along the gas flow holes 125, and finally diffuse to the surroundings along the gas discharge holes 126 to dry the contacted fertilizer particles. When the fertilizer is dried, the driving motor 9 and the blower dryer are turned off, and the blocking plate 6 is opened to collect the dried fertilizer below.
