Through local heating, the heating demand of the entire system can be reduced, thereby reducing the energy consumption of the high-pressure air pump, preventing the material from agglomerating during the falling process, maintaining the fluidity of the material, and improving the convenience of subsequent processing.

[0019] It also includes a material box 2, which is fixedly installed on one side of the installation cover 15. The material box 2 and the drying tower 1 are jointly installed with an atomizing box 5 through a feeding structure. The feeding structure includes a pad fixedly installed on the drying tower 1, and a pump 3 is fixedly installed on the pad.

The atomizing box 5 is also funnel-shaped, with a smooth inner edge and no edges and corners, which can prevent the material from accumulating in the atomizing box 5 and being difficult to discharge.

[0020] A motor 6 is fixedly mounted on the atomizing box 5, and an atomizing structure for atomizing the material is installed between the motor 6 and the atomizing box 5. The atomizing structure includes a fixed tube 7 fixedly mounted on the driving end of the motor 6, and the fixed tube 7 rotates and penetrates the atomizing box 5.

The atomizing nozzle 9 is a prior art, which compresses the liquid through a high-pressure pump and sprays it through a nozzle to form mist particles that are sprayed into the drying tower 1. The funnel-shaped setting at the bottom of the drying tower 1 increases the area and time of the material being dried by the heating ring 16, improves the drying efficiency of the material, and ensures that it slides down along the inside of the drying tower 1 and accumulates at the bottom.

[0021] Reference Figure 1 , Figure 6-Figure 11 , and also includes two fixed plates 11, both of which are fixedly installed on one side of the drying tower 1, and a vacuum pump 12 is fixedly installed between the two fixed plates 11. The design of the vacuum pump 12 is usually relatively simple, and the working principle of the vacuum pump 12 can refer to the water ring vacuum pump; an output crushing structure for crushing the material and extracting it is installed between the vacuum pump 12 and the drying tower 1, and the output crushing structure includes a rotating shaft 35 rotatably installed on one of the fixed plates 11, and a connecting gear 34 is fixedly installed on the upper end of the rotating shaft 35, and the connecting gear 34 is fixedly connected to the driving end inside the vacuum pump 12 (an impeller is arranged inside the vacuum pump 12, and the design and rotation speed of the impeller directly affect the pumping capacity and efficiency of the pump. An efficient impeller can increase the pumping rate and reduce energy consumption).

[0022] The drying tower 1 is provided with an operation panel 19, which is electrically controlled with the pump 3, the motor 6, the high-pressure air pump and the vacuum pump 12, and can control the individual operation of each structure, so as to facilitate operation by personnel.

[0023] The fixed plate 11 is provided with a force storage spring, a short shaft is rotatably provided on the fixed plate 11, a speed regulating gear 33 is fixedly provided on the upper end of the force storage spring, and the speed regulating gear 33 is fixedly provided on the short shaft, the speed regulating gear 33 is meshed with the connecting gear 34, a crushing mechanism is provided on the vacuum pump 12, the crushing mechanism comprises an extraction pipe 13 fixedly connected to the lower end of the vacuum pump 12, an extraction pipe 14 is fixedly connected between the extraction pipe 13 and the drying tower 1, an accumulation barrel 20 is fixedly connected to the lower end of the extraction pipe 13, a cutting shaft 21 is rotatably provided in the accumulation barrel 20, a plurality of cutting rods 22 for crushing the materials are fixedly provided on the cutting shaft 21, an extraction component is installed between the cutting rod 22 and the accumulation barrel 20, The extraction component includes a mounting groove opened at the bottom of the stacking cylinder 20, a gear 27 is fixedly installed on the cutting shaft 21, and the gear 27 is rotatably set in the mounting groove, two reciprocating screws 26 are rotatably installed in the mounting groove, and a gear 28 meshing with the gear 27 is fixedly installed on the two reciprocating screws 26, and a piston plate 25 is threadedly installed on the two reciprocating screws 26, and when the two reciprocating screws 26 rotate in the same direction, the two piston plates 25 at this time move in opposite directions, and the lower surface of the stacking cylinder 20 is fixedly connected with a discharge pipe 23 and two vacuum cylinders 24, and the two piston plates 25 are respectively sealed and slid in the corresponding vacuum cylinders 24, and a one-way extraction pipe is fixedly connected between the two vacuum cylinders 24 and the discharge pipe 23.

[0024] A transmission component is installed between the cutting rod 22 and the short shaft, and the transmission component includes a one-way bearing rotatably arranged at the lower end of the cutting shaft 21. A support block 29 is fixedly installed on one side of the stacking cylinder 20, and a rotating rod 30 is rotatably arranged on the support block 29. A pulley 1 is fixedly arranged on the lower end of the rotating rod 30 and the one-way bearing, and a conveyor belt 1 31 is rotatably sleeved between the two pulleys 1. A pulley 2 is fixedly installed on the upper end of the rotating rod 30 and the short shaft, and a conveyor belt 2 32 is rotatably sleeved between the two pulleys 2. When the vacuum pump 12 is working, the one-way bearing is in a rotating state. After the material collection is completed, the rebound of the force storage torsion spring drives the connecting gear 34 to rotate in the opposite direction and reset. At this time, the one-way bearing is in a locked state.

[0025] The dried material will be accumulated at the upper pipe opening of the extraction pipe 14. At this time, the vacuum pump 12 is turned on to collect the dried material through the extraction pipe 13 and the extraction pipe 14, and then the dried material is pumped into the stacking tube 20. During this process, the rotating shaft 35 of the impeller in the vacuum pump 12 drives the connecting gear 34 to rotate, thereby driving the speed regulating gear 33 to rotate at a lower speed. The rotation of the speed regulating gear 33 drives the cutting shaft 21 to rotate through the cooperation of the rotating rod 30, the conveyor belt 2 32 and the conveyor belt 1 31. When the cutting shaft 21 rotates, the multiple cutting rods 22 thereon crush and scatter the dried material entering the stacking tube 20. At the same time, the cooperation of the gear 1 27 and the two gears 28, The two piston plates 25 move up and down in the two vacuum cylinders 24 respectively, and negative pressure is generated in the discharge pipe 23 through the two one-way vacuum pipes, so that the material in the extraction pipe 13 can enter the stacking cylinder 20 under the action of pressure. The cutting and crushing effect can be improved by cooperating with the rotation of the cutting rod 22 during the falling process of the material. The moving directions of the two piston plates 25 are opposite. Therefore, as long as the cutting shaft 21 rotates, there must be a vacuum cylinder 24 to generate negative pressure in the discharge pipe 23 to ensure the extraction effect of the material. Since the negative pressure always exists, the smooth discharge of all materials can be ensured, the speed of material discharge can be increased, and at the same time, the particles after atomization drying can be prevented from agglomerating.

[0026] The specific operation steps of the present invention are: By controlling the operation panel 19, the pump 3 is turned on to input the material in the material box 2 into the atomizing box 5. At this time, the motor 6 is turned on to make it work. The motor 6 can drive the fixed tube 7 to rotate. The rotation of the fixed tube 7 drives the multiple stirring rods 10 to stir the material, thereby accelerating the speed at which the material enters the fixed tube 7 through the alignment hole 8 to prevent it from precipitating and clogging the atomizing nozzle 9. The material is sprayed into the drying tower 1 under the power of the atomizing nozzle 9. With the funnel-shaped setting at the bottom of the drying tower 1, the area and time of the material being dried by the heating ring 16 are increased, the drying efficiency of the material is improved, and the material is atomized. At the same time, the high-pressure air pump is turned on, and the heating ring 16 is turned on to run. The air is heated by the heating ring 16, and the high-temperature gas is sent into the drying tower 1 through the cooperation of the connecting pipe 17 and the short pipe 18 to dry the atomized raw materials. After the material is dried, the vacuum pump 12 is turned on to collect the dried material through the extraction pipe 13 and the extraction pipe 14, and the dried material is pumped into the stacking barrel 20. During this process, the rotating shaft 35 of the impeller in the vacuum pump 12 drives the connecting gear 34 to rotate, thereby driving the speed regulating gear 33 to rotate at a lower speed. The rotation of the speed regulating gear 33 drives the short shaft to rotate, and the short shaft drives the rotating rod 30 to rotate through the conveyor belt 2 32. The rotation of the rotating rod 30 drives the conveyor belt 1 31 to rotate. The rotation of the conveyor belt 1 31 drives the cutting shaft 21 to rotate through the one-way bearing. At this time, the force storage spring is in a force storage state. The rotation of the cutting shaft 21 drives the multiple cutting rods 22 to rotate. The multiple cutting rods 22 crush and scatter the material that enters the stacking barrel 20 after drying. The rotation of the cutting shaft 21 drives the gear 1 27 to rotate. The rotation of the gear 1 27 drives the two gears 28 to rotate. The two gears 28 rotate The two reciprocating screw rods 26 are driven to rotate, so that the two piston plates 25 move up and down in the two vacuum cylinders 24 respectively, and the discharge pipe 23 generates negative pressure through the two one-way vacuum pipes, so that the material in the extraction pipe 13 can enter the stacking cylinder 20 under the action of pressure. The rotation of the cutting rod 22 during the falling process of the material can improve the cutting and crushing effect. When the material is crushed and cut, the vacuum pump 12 stops running and drives the speed regulating gear 33 to rotate in the opposite direction under the action of the force storage spring. At this time, the cutting shaft 21 stops rotating, but the gear 1 27 rotates in the opposite direction under the action of the one-way bearing, driving the two gears 28 to rotate in the opposite direction. At this time, the other piston plate 25 generates negative pressure in the stacking cylinder 20. Since there is always negative pressure in the stacking cylinder 20, it can ensure the smooth discharge of all materials, increase the speed of material discharge, and ensure the uniformity and dryness of material particles.

It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
