Description

Technical Field

[0001] This application relates to the field of mixing equipment technology, and in particular to a rapid pesticide mixing device. Background Technology

[0002] When processing pesticide powders, various powdered substances need to be mixed, requiring a suitable mixing device. A patent document with authorization publication number CN221015472U discloses a rapid pesticide mixing device, relating to the field of mixing device technology. The device features a base plate fixedly connected to the inner side of a frame structure. The base and base plate together form a support structure, and a heater is installed on the top surface of the base plate. This addresses the limitation of existing devices that lack effective heating and baking structures, making them susceptible to moisture in the powder affecting normal pesticide mixing. By incorporating a base plate and heater, the device can spray air by activating the heater on top of the base plate. Simultaneously, the heating wire within the heater heats the sprayed air, which is then rapidly ejected via an air duct on top of the heater, achieving a more practical purpose.

[0003] The above solution still has at least the following shortcomings in actual use: the method of using hot air from the air duct to blow upwards to heat and dry the pesticide powder in the tank results in low utilization of heat in the hot air, low heating and drying efficiency of pesticide powder, long heating and drying time, and insufficient energy saving.

[0004] Therefore, we propose a rapid pesticide mixing device to solve the above problems. Utility Model Content

Detailed Implementation

[0024] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This application provides a rapid pesticide mixing device, including a frame 1 and a pesticide mixing tank 2 fixedly mounted on the top of the frame 1. The pesticide mixing tank 2 has a mixing chamber 7, the diameter of which increases from both sides towards the center. A pesticide powder inlet pipe 3 is fixedly installed at the center of the top of the pesticide mixing tank 2, and an end cap 4 is threaded onto the top of the pesticide powder inlet pipe 3. A pesticide powder outlet pipe 5 is fixedly installed at the center of the bottom of the pesticide mixing tank 2, and an end cap 6 is threaded onto the bottom of the pesticide powder outlet pipe 5. Wherein:

[0026] The pesticide mixing tank 2 is equipped with a stirring and mixing mechanism. This mechanism is used to stir and mix the pesticide powder within the mixing tank 2. The stirring and mixing mechanism includes a hollow horizontal shaft 8, three U-shaped heat-conducting hollow tubes 9, multiple stirring rods 10, multiple crushing blades 11, and a drive assembly. The hollow horizontal shaft 8 is rotatably mounted inside the pesticide mixing tank 2. The three U-shaped heat-conducting hollow tubes 9 are all fixedly mounted on the hollow horizontal shaft 8 and are arranged in an evenly spaced ring. Both ends of the U-shaped heat-conducting hollow tubes 9 extend into the hollow horizontal shaft 8. A stirring rod 10 is fixedly mounted on three U-shaped heat-conducting hollow tubes 9 and evenly distributed. Multiple crushing blades 11 are fixedly mounted on a hollow horizontal shaft 8 and evenly distributed. Both ends of the hollow horizontal shaft 8 extend outside the pesticide mixing tank 2. A drive assembly is located on the left side of the pesticide mixing tank 2. The drive assembly is used to control the rotation of the hollow horizontal shaft 8. The drive assembly includes a support base 12, a motor 13, a main gear 14, and a secondary gear 15. The support base 12 is fixedly mounted on the left outer wall of the pesticide mixing tank 2, and the motor 13 is fixedly mounted on... At the top of the support base 12, the main gear 14 is fixedly mounted on the output shaft end of the motor 13, and the auxiliary gear 15 is fixedly fitted around the hollow horizontal shaft 8 and located on the left side of the pesticide mixing tank 2. The main gear 14 and the auxiliary gear 15 mesh, and the output shaft of the motor 13 can drive the main gear 14 to rotate. Under the meshing transmission action of the main gear 14 and the auxiliary gear 15, the rotation of the hollow horizontal shaft 8 can be controlled, so that the three U-shaped heat-conducting hollow tubes 9, multiple stirring rods 10, and multiple crushing blades 11 rotate synchronously with the hollow horizontal shaft 8. Through the synergistic action of the hollow horizontal shaft 8, three U-shaped heat-conducting hollow tubes 9, multiple stirring rods 10, and multiple crushing blades 11, the pesticide powder in the mixing chamber 7 can be stirred and mixed in all directions. The U-shaped heat-conducting hollow tubes 9, which are distributed in a ring at equal intervals, together with the stirring rods 10 evenly distributed on them, can ensure that the pesticide powder is fully tumbled in the mixing chamber 7. The multiple crushing blades 11 can break up and disperse the clumps of pesticide powder in time, which greatly improves the uniformity and efficiency of mixing and further enhances the uniformity of pesticide powder mixing.

[0027] In this embodiment, a heating and baking mechanism is provided between the pesticide mixing tank 2 and the frame 1. The heating and baking mechanism is used to heat and dry the pesticide powder. The heating and baking mechanism includes a heating box 16, multiple spiral electric heating wires 17, a circulating fan 18, an air intake pipe 19, an air outlet pipe 20, and a return pipe 21. The heating box 16 is fixedly installed on the frame 1. The multiple spiral electric heating wires 17 are all fixedly installed inside the heating box 16 and arranged in an array. The circulating fan 18 is fixedly installed on the left outer wall of the heating box 16. One end of the air intake pipe 19 is fixedly connected to the intake end of the circulating fan 18, and the other end of the air intake pipe 19 extends into the heating box 16. One end of the air outlet pipe 20 is fixedly connected to the discharge end of the circulating fan 18, and the return pipe 21 is fixedly installed. Installed on the right side wall of the heating chamber 16, one end of the return air pipe 21 extends into the heating chamber 16, and the other end of the air outlet pipe 20 and the other end of the return air pipe 21 extend into the two ends of the hollow horizontal shaft 8, respectively. Heat is generated by multiple spiral electric heating wires 17 inside the heating chamber 16. The hot air inside the heating chamber 16 is transported into the hollow horizontal shaft 8 through the air intake pipe 19 and the air outlet pipe 20 by the circulating fan 18, and then returned to the heating chamber 16 through the return air pipe 21, forming a heat circulation. This design can uniformly, comprehensively and efficiently heat and dry the pesticide powder during the stirring process, remove the moisture, and prevent the pesticide powder from being affected by moisture, thus affecting the stirring and mixing efficiency and the quality of pesticide production. It achieves the function of efficient and energy-saving heating and drying of pesticide powder.

[0028] In this embodiment, it should be noted that the hollow horizontal shaft 8, the U-shaped heat-conducting hollow tube 9, the stirring rod 10, and the crushing blade 11 are all made of the same material, namely stainless steel and other metal materials with good thermal conductivity and corrosion resistance. This ensures that the heat in the hot air is more fully and comprehensively transferred to the pesticide powder during the stirring and drying process, thereby further improving the heating and drying effect and efficiency of the pesticide powder.

[0029] In this embodiment, sealing rings 22 are fixedly installed on the inner walls of both ends of the hollow horizontal shaft 8. The air outlet pipe 20 and the air return pipe 21 are rotatably sealed to both ends of the hollow horizontal shaft 8 through the corresponding sealing rings 22. The design of the two sealing rings 22 ensures that the air outlet pipe 20 and the air return pipe 21 are rotatably sealed to the hollow horizontal shaft 8, avoiding hot air leakage and ensuring the heating and baking effect. Reinforcing rods 23 are fixedly installed on both sides of the bottom of the pesticide mixing tank 2. One end of the two reinforcing rods 23 is fixedly connected to the air outlet pipe 20 and the air return pipe 21, respectively. The design of the two reinforcing rods 23 enhances the stability of the air outlet pipe 20 and the air return pipe 21, making the whole device more reliable during operation. A support plate 24 is fixedly installed on the frame 1. The support plate 24 is located between the pesticide mixing tank 2 and the heating box 16. The design of the support plate 24 is to facilitate the placement of the receiving box. After the pesticide powder is mixed, stirred and dried, it is convenient to use the receiving box to collect the pesticide powder discharged from the pesticide powder discharge pipe 5.

[0030] In this embodiment, a moisture discharge pipe 25 is fixedly installed on the top of the pesticide mixing tank 2, and an electromagnetic shut-off valve is fixedly installed on the moisture discharge pipe 25. One end of the moisture discharge pipe 25 extends into the mixing chamber 7 and is fixedly installed with a baffle net. The design of the moisture discharge pipe 25 and the electromagnetic shut-off valve can discharge the moisture generated during the drying process in a timely manner. The baffle net can prevent pesticide powder from being discharged with the moisture, ensuring the effective utilization of pesticide powder and further improving the drying effect and product quality.

[0031] In this embodiment, it should be noted that the motor 13, the spiral electric heating wire 17, the circulating fan 18, and the electromagnetic shut-off valve are all commercially available. Their wiring connection methods and control methods are mature technologies in the field and have been fully disclosed, so they will not be described again in this article.

[0032] Based on the above structure, the working principle of the pesticide rapid mixing device provided in this application is as follows:

[0033] First, unscrew end cap 4 and pour various pesticide powders for pesticide production into pesticide mixing tank 2 from pesticide powder inlet pipe 3 according to the ratio. Then, screw end cap 4 back onto the top of pesticide powder inlet pipe 3. Next, control motor 13 starts working, and its output shaft drives main gear 14 to rotate. Since main gear 14 meshes with secondary gear 15, secondary gear 15 will follow main gear 14 to rotate, thereby driving hollow horizontal shaft 8 to start rotating in pesticide mixing tank 2. As hollow horizontal shaft 8 rotates, the three U-shaped heat-conducting hollow tubes 9 fixedly installed on it also rotate. Stirring rods 10 evenly distributed on U-shaped heat-conducting hollow tubes 9 will push the pesticide powder in the mixing chamber 7 of pesticide mixing tank 2 to roll and move. At the same time, multiple crushing blades 11 installed on hollow horizontal shaft 8 will crush any clumps of pesticide powder. Through the tumbling of stirring rods 10 and crushing of crushing blades 11, efficient stirring and uniform mixing of pesticide powder is achieved.

[0034] During the mixing of pesticide powder, multiple spiral electric heating wires 17 inside the heating chamber 16 are turned on to generate heat, raising the temperature of the air inside the heating chamber 16. Simultaneously, the circulating fan 18 is activated, drawing the hot air from the heating chamber 16 through the suction pipe 19 and then through the exhaust pipe 20 to the hollow horizontal shaft 8. This allows the hot air to flow within the hollow horizontal shaft 8 and the three U-shaped heat-conducting hollow pipes 9, transferring heat to the mixing chamber 7 to heat and dry the pesticide powder. The released, low-temperature hot air flows back to the heating chamber 16 through the return pipe 21 for reheating and recycling. This achieves efficient, uniform, and comprehensive heating and drying of the pesticide powder, removing moisture and preventing it from affecting mixing efficiency and pesticide production quality. This results in efficient and energy-saving heating and drying of the pesticide powder.

[0035] During the mixing and heating process of pesticide powder, the moisture in the pesticide powder is evaporated into water vapor, the gas pressure in the mixing chamber 7 increases, the electromagnetic shut-off valve is opened, and the gas containing moisture in the mixing chamber 7 is discharged through the moisture discharge pipe 25. The baffle net effectively prevents the pesticide powder from being discharged with the gas, ensuring that the amount of pesticide powder is not lost, while ensuring the smooth discharge of moisture during the drying process, maintaining a good drying environment to improve the drying effect and product quality.

[0036] After the pesticide powder is mixed and heated and dried, stop the motor 13, turn off the multiple spiral electric heating wires 17 and the circulating fan 18, take a receiving box and place it on the support plate 24, unscrew the end cap 2 6, and the pesticide powder in the pesticide mixing tank 2 can be discharged through the pesticide powder discharge pipe 5 and fall into the receiving box.
