The extracted air can be discharged to a suitable gas treatment device such as an air filter through the air outlet of the exhaust fan 3 for treatment.
[0023] The dissolving vessel body 1 has a first feed pipe 2 at the top center. Pesticide production raw materials can be injected into the dissolving vessel through the first feed pipe 2. The top of the first feed pipe 2 is equipped with an electric ball valve, so that the inner cavity of the dissolving vessel body 1 is sealed during the dissolution and mixing process of agricultural production raw materials to prevent the leakage of toxic gases. The bottom of the dissolving vessel body 1 has a discharge pipe 19 on one side. After the pesticide production raw materials are dissolved and mixed evenly, they are discharged through the discharge pipe 19. Another electric ball valve is equipped on one side of the discharge pipe 19.
[0024] A stirring rod 5 is movably connected to the middle of the inner cavity of the dissolving vessel body 1. The bottom of the stirring rod 5 extends to the bottom of the dissolving vessel body 1. A servo motor 4 is fixedly connected to one side of the dissolving vessel body 1. The stirring rod 5 is driven by the servo motor 4. When the servo motor 4 rotates, it can drive the stirring rod 5 to rotate.
[0025] Stirring blade 2 is uniformly fixedly connected to the outer ring at the bottom of stirring rod 5. The other end of stirring blade 2 is in contact with the inner wall of the dissolving vessel body 1. Stirring blade 16 is uniformly fixedly connected to the outer ring at the top of stirring rod 5. When stirring rod 5 rotates, it can drive stirring blade 16 and stirring blade 2 to rotate.
[0026] The bottom end of the stirring rod 5 is hollow, and liquid inlet holes are evenly distributed on the side wall of the bottom end of the stirring rod 5. Liquid around the stirring rod 5 can enter the inner cavity of the bottom end of the stirring rod 5 through the liquid inlet holes. A rotating drum 8 is movably connected to the bottom of the inner cavity of the bottom end of the stirring rod 5. A discharge pipe 6 is fixedly connected to one side of the bottom of the rotating drum 8. Material can enter the inner cavity of the discharge pipe 6 through the rotating drum 8.

[0027] A circulation pump 7 is installed at the bottom of the dissolving vessel body 1. The other end of the discharge pipe 6 is connected to the inlet end of the circulation pump 7, and the other end of the second inlet pipe 12 is connected to the outlet end of the circulation pump 7. As can be seen from the above description, when the circulation pump 7 is working, it can pump the liquid material into the inner cavity of the spray ring 13. The liquid raw material in the inner cavity of the spray ring 13 is sprayed out through the spray hole. Under the action of gravity, the sprayed raw material can be remixed with the material in the dissolving vessel body 1. This operation expands the movement range of the material and improves the dissolution and mixing speed of the material.
[0028] The bottom of the first feed pipe 2 is provided with a receiving cylinder 10. A scraper rod 15 is fixedly connected to the bottom end of the inner cavity of the receiving cylinder 10. A bottom plate 11 is movably connected inside the inner cavity of the receiving cylinder 10. The bottom plate 11 is located below the scraper rod 15, and the middle part of the bottom plate 11 is movably connected to the stirring rod 5. A hydraulic telescopic rod 17 is fixedly connected to one side of the top of the bottom plate 11. The other end of the hydraulic telescopic rod 17 is fixedly connected to the stirring rod 5. By setting the hydraulic telescopic rod 17, the extension and retraction of the hydraulic telescopic rod 17 can change the position of the bottom plate 11. When the bottom plate 11 seals the bottom of the receiving cylinder 10, the bottom plate 11 and the receiving cylinder 10 form a collecting cylinder for collecting a small amount of solid raw material put into the dissolving kettle. At this time, the small amount of solid raw material is dissolved in the collecting cylinder. When a large amount of solid raw material is put into the dissolving kettle, the bottom plate 11 separates from the receiving cylinder 10 to facilitate the falling of the solid raw material.
[0029] Both the receiving cylinder 10 and the bottom plate 11 are provided with mesh holes to facilitate the falling of the dissolved raw materials. A sealing strip is fixedly connected to the outer wall of the bottom plate 11 to improve the sealing between the bottom plate 11 and the receiving cylinder 10.
[0030] The other end of the stirring blade 16 contacts the inner wall of the receiving cylinder 10. A side scraper 14 is fixedly connected to the outer wall of the spray ring 13. The bottom of the side scraper 14 is at the same height as the top of the scraper rod 15. The side scraper 14 contacts the inner wall of the receiving cylinder 10. Through the setting of the side scraper 14 and the scraper rod 15, the solid raw materials adhering to the collecting cylinder can be scraped off, which facilitates the dissolution of the solid raw materials.
[0031] As can be seen from the above description, during the use of this dissolving kettle, a small amount of solid raw material is dissolved in the collection cylinder composed of the receiving cylinder 10 and the bottom plate 11, and the solid raw material is dissolved in the liquid raw material lifted by the circulating pump 7.
[0032] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.
[0033] In summary: When using this high-efficiency pesticide production dissolving kettle, the pesticide production raw materials enter the dissolving kettle through the first feed pipe 2. During the feeding process, the negative pressure structure works, and the exhaust fan 3 draws away some of the air in the dissolving kettle. The air around the dissolving kettle enters the dissolving kettle through the one-way air supply valve 9, preventing the leakage of toxic gases during the feeding process. The gas extracted by the exhaust fan 3 can be passed into air filters and other gas treatment equipment for treatment. During use, the servo motor 4 drives the stirring rod 5 to rotate, which stirs the surrounding materials, accelerating the mixing and dissolving speed. The circulation pump 7 operates, lifting the liquid raw material at the bottom of the inner cavity of the dissolving vessel body 1 into the spray ring 13 and spraying it out through the spray holes, expanding the movement range of the liquid raw material and increasing the mixing and dissolving speed. When a small amount of solid raw material needs to be added to a large amount of liquid raw material, the bottom plate 11 seals the bottom of the receiving cylinder 10, and the solid raw material is collected by the collection cylinder composed of the bottom plate 11 and the receiving cylinder 10. The solid raw material is concentrated and dissolved in the collection cylinder, which can quickly eliminate clumping and wall adhesion, and improve pesticide production efficiency.
