[0020] like Figure 1-5 As shown in the figure, the microcapsule pesticide processing and mixing device described in this embodiment includes a liquid mixing tank 1, a spray pipe 2 and a drying tower 3. An electric stirring shaft is installed in the liquid mixing tank 1. The upstream end of the spray pipe 2 is connected to the liquid mixing tank 1, and the downstream end extends into the drying tower 3 and is equipped with a spray head. A pump is also installed on the spray pipe 2.

[0021] The drying tower 3 includes an ascending section 4 and an expansion section 5. The expansion section 5 has a horizontal air outlet 6 and a downward outlet 7. The dried material is discharged through the outlet 7. An air duct 8 is installed at the horizontal air outlet 6. To prevent a large amount of material from entering the horizontal air outlet 6, a filter screen is installed at the horizontal air outlet 6 to intercept the material.

[0022] A hot air blower 9 is installed at the bottom of the drying tower 3. The hot air blower 9 includes a bottom chamber 10, an air inlet jacket 11, a heating chamber 12, and a rectifier chamber 13 arranged sequentially from bottom to top. The air inlet jacket 11 is connected to the left and right sides by blower pipes 14, and blowers are installed on the blower pipes 14. A bottom exhaust duct 15 is installed in the middle of the air inlet jacket 11. The bottom exhaust duct 15 has a lower opening and strip-shaped holes 16 on the left and right sides that communicate with the air inlet jacket 11. Two connecting turbulence arrays are also symmetrically arranged on the air inlet jacket 11 on the left and right sides of the bottom exhaust duct 15. The connecting turbulence array includes multiple connecting turbulence pipe groups evenly distributed in the front and back direction. The connecting turbulence pipe groups connect the bottom chamber 10 and the heating chamber 12. The bottom chamber 10 is equipped with a sloped air guide block 17 that cooperates with the connecting turbulence array, so that the airflow can better gather towards the lower opening of the connecting turbulence pipe group. The connecting turbulence pipe group includes a vertically arranged rectangular pipe 18 and a T-shaped pipe 19.

[0023] The heating chamber 12 is equipped with a heating tube 20 and a baffle plate 21. The airflow entering the heating chamber 12 changes direction under the action of the baffle plate 21, extending the flow path of the airflow and allowing it to fully contact the heating tube 20 for heat exchange. A hot air outlet 22 is provided at the top of the heating chamber 12, and the hot air outlet 22 is connected to the rectifier chamber 13. Multiple air distribution holes 23 are evenly distributed on the top surface of the rectifier chamber 13. Specifically, multiple concentric circular air distribution channels are provided in the rectifier chamber 13. The hot air outlet 22 is connected to the outermost circular air distribution channel. A connecting port 24 is provided between adjacent air distribution channels. A ring array of air distribution holes corresponding to each circular air distribution channel is provided on the top surface of the rectifier chamber 13.

[0024] The working principle of this embodiment is as follows:

[0025] After the core material and wall material are emulsified, they are mixed in the liquid mixing box 1 and then sprayed into the drying tower 3 through the spray pipe 2. The hot air blower 9 outputs hot air upwards simultaneously. When the hot air blower 9 is running, the external airflow is blown into the air inlet jacket 11 from the left and right sides, forming multiple airflow vortices downstream of the connecting turbulence pipe group. The airflow vortices entering from the left and right sides of the bottom exhaust duct 15 collide and break up to form turbulent airflow. The turbulent airflow turns in the bottom chamber 10 and reaches the heating chamber 12 through the connecting turbulence pipe group. After being heated by the heating pipe 20 in the heating chamber 12, it enters the rectifier chamber 13 through the hot air outlet 22 and finally enters the drying tower 3 upwards through the air distribution hole 23 to blow up and dry the material. The airflow carrying the material reaches the expansion section 5 and the gas velocity decreases. After drying, the material falls out through the outlet 7, and the airflow enters the air duct 8 through the horizontal air outlet 6. Compared with the prior art, the hot air blower 9 has a higher heat exchange efficiency when generating hot air in this embodiment, which can reduce the energy consumption of the hot air blower 9, which is conducive to energy conservation and environmental protection and reduces production and operating costs.

[0026] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
