Description

Technical Field

[0001] This application relates to the field of mixing machinery technology, and in particular to a high-efficiency premixing reactor for pesticide production. Background Technology

[0002] Pesticides refer to chemically synthesized substances or mixtures of substances derived from biological or other natural materials, used to prevent and control diseases, insects, weeds, rodents, and other harmful organisms that threaten agriculture and forestry, as well as to purposefully regulate the growth of plants and insects. They are widely used in agricultural, forestry, and animal husbandry production, environmental and household sanitation pest control and disease prevention, and industrial product mildew and insect prevention. In the pesticide production process, a premixing reactor is needed to dissolve and mix various liquid and solid raw materials for pesticide preparation evenly before proceeding to the next processing step.

[0003] A search revealed a patent document with authorization announcement number CN213556528U that discloses a high-efficiency premixing vessel for pesticide preparation, comprising a vessel body, vessel base, jacket, reinforcing wall, rotary motor, rotary shaft, rotary blades, small blades, main material inlet, auxiliary material inlet, temperature display, temperature measuring head, discharge valve, storage tank, and delivery pump.

[0004] Although the above scheme can meet the basic requirements for mixing raw materials for pesticide preparation, it has been found that there are still at least the following shortcomings in actual use: during the mixing process, solid raw materials cannot be completely and quickly crushed, resulting in a relatively slow rate at which solid raw materials dissolve in liquid raw materials, which in turn prolongs the mixing time and reduces the mixing efficiency.

[0005] Therefore, we propose a high-efficiency premixing reactor for pesticide production to solve the above problems. Utility Model Content

Detailed Implementation

[0025] 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.

[0026] See Figures 1-5 This application provides a high-efficiency premixing reactor for pesticide production, including a reactor body 1. Support legs 2 are fixedly installed at the bottom of the reactor body 1. A feed hopper 3 is fixedly installed on the outer wall of the reactor body 1 to facilitate the pouring of raw materials for pesticide preparation into the reactor body 1. The bottom of the reactor body 1 has a concave arc-shaped structure to facilitate the smooth discharge of uniformly mixed raw materials. A discharge pipe 4 is fixedly installed at the center of the bottom of the reactor body 1, and an electromagnetic discharge valve 5 is fixedly installed on the discharge pipe 4 to facilitate the smooth discharge of the mixed material, improving the convenience and controllability of production operations. A vertical shaft 6 is rotatably installed inside the reactor body 1, and a fixed... A partition 7 is installed, which divides the interior of the vessel body 1 into two spaces. It should be noted that the end of the feed hopper 3 fixedly connected to the vessel body 1 is located below the partition 7, thus ensuring that the raw materials poured into the vessel body 1 are below the partition 7. A diamond-shaped stirring rod 8 is fixedly installed on the vertical shaft 6, located below the partition 7. A motor 9 is fixedly installed on the top of the vessel body 1. The top end of the vertical shaft 6 extends outside the vessel body 1 and is fixedly connected to the output shaft end of the motor 9. The motor 9 controls the rotation of the vertical shaft 6, the partition 7, and the diamond-shaped stirring rod 8. The diamond-shaped stirring rod 8 can be used to stir and mix the raw materials.

[0027] An internal gear ring 10 is fixedly installed on the inner top wall of the vessel body 1. A crushing mechanism 11 is provided on the partition 7. The crushing mechanism 11 is used to crush the solid raw materials for preparing pesticides. The crushing mechanism 11 includes a raw material crushing component 111 and a transmission component 112. The raw material crushing component 111 includes a main shaft 1111, a secondary shaft 1112 and several crushing teeth 1113. The main shaft 1111 and the secondary shaft 1112 are both rotatably installed at the bottom of the partition 7. The top ends of the main shaft 1111 and the secondary shaft 1112 are both through-holes. A partition 7 and several crushing teeth 1113 are fixedly installed on the main shaft 1111 and the secondary shaft 1112 and are evenly distributed. The crushing teeth 1113 on the main shaft 1111 and the crushing teeth 1113 on the secondary shaft 1112 are alternately distributed. Through the combined action of the crushing teeth 1113 on the main shaft 1111 and the crushing teeth 1113 on the secondary shaft 1112, solid raw materials can be crushed, allowing the solid raw materials to dissolve more quickly in the liquid raw materials, improving mixing efficiency. The transmission component 112 includes a transmission... The main shaft 1111 consists of a drive gear 1121, a main gear 1122, and a secondary gear 1123. The top end of the main shaft 1111 extends into the internal gear ring 10. The drive gear 1121 is fixedly fitted onto the top end of the main shaft 1111 and meshes with the internal gear ring 10. The main gear 1122 is fixedly fitted onto the main shaft 1111 and located between the internal gear ring 10 and the partition 7. The secondary gear 1123 is fixedly fitted onto the top end of the secondary shaft 1112. The main gear 1122 and the secondary gear 1123 mesh. When the partition 7 drives the main shaft 1111... During the horizontal rotation of the main shaft 11 and the secondary shaft 1112 around the vertical shaft 6, the meshing transmission action of the transmission gear 1121 and the internal gear ring 10 can control the rotation of the main shaft 1111. The meshing transmission action of the main gear 1122 and the secondary gear 1123 can make the main shaft 1111 and the secondary shaft 1112 rotate simultaneously, and the main shaft 1111 and the secondary shaft 1112 rotate in opposite directions. This can effectively crush the solid raw materials and further improve the uniformity of the raw material mixing.

[0028] In this embodiment, the number of crushing mechanisms 11 is no less than three sets, and they are evenly distributed in a ring with the vertical axis 6 as the center. This can fully and efficiently crush the solid raw materials for preparing pesticides, accelerate the dissolution of solid raw materials in liquid raw materials, improve the mixing uniformity of raw materials, and help improve the quality of pesticide products.

[0029] In this embodiment, a sealing ring 13 is fixedly fitted on the outer wall of the partition 7. The outer ring wall of the sealing ring 13 slides and seals with the inner wall of the vessel body 1, which can effectively prevent the raw materials from leaking from the gap between the partition 7 and the inner wall of the vessel body 1 during the stirring process. The raw materials will not enter the space above the partition 7, ensuring the sealing of the production process.

[0030] In this embodiment, it should be noted that both the electromagnetic discharge valve 5 and the motor 9 are commercially available. The electromagnetic discharge valve 5 and the motor 9 are equipped with power supplies, and their circuit connection and control methods are mature technologies in the field and are fully disclosed. Therefore, they will not be described in detail here.

[0031] With the above structure, when the high-efficiency premixing kettle for pesticide production provided in this application is used, the weighed and proportioned solid raw materials and liquid raw materials are poured into the kettle body 1 from the feed hopper 3 in sequence. When the motor 9 runs, the motor 9 drives the vertical shaft 6 to rotate, and the partition 7 on the vertical shaft 6 rotates accordingly. At the same time, the diamond-shaped stirring rod 8 fixed on the vertical shaft 6 also starts to rotate, so that the raw materials can be stirred.

[0032] The crushing mechanism 11 at the bottom of the partition 7 moves along with the vertical shaft 6, which can also stir and mix the raw materials. The transmission gear 1121 at the top of the main shaft 1111 meshes with the internal gear ring 10 on the inner wall of the top of the vessel 1. When the vertical shaft 6 drives the partition 7 to rotate, the main shaft 1111 will rotate under the action of the internal gear ring 10. When the main shaft 1111 rotates, the main gear 1122 fixedly mounted on the main shaft 1111 rotates, which in turn drives the secondary gear 1123 meshing with it to rotate, causing the secondary shaft 1112 to rotate as well. By utilizing the crushing teeth 1113 that are evenly distributed and alternately arranged on the main shaft 1111 and the secondary shaft 1112, the solid raw materials can be effectively crushed during the rotation. Since there are no less than three sets of crushing mechanisms 11 that are evenly distributed in a ring, the raw materials can be fully and thoroughly crushed, thereby accelerating the speed at which the solid raw materials dissolve in the liquid raw materials and improving the mixing uniformity and mixing efficiency of the raw materials.

[0033] Once the mixture is homogeneous, open the electromagnetic discharge valve 5 on the discharge pipe 4. The homogeneous raw material will be discharged smoothly through the discharge pipe 4 under the action of gravity.

[0034] In this embodiment, a scraper 12 is fixedly installed on the vertical shaft 6. The scraper 12 is used to scrape off the raw materials adhering to the inner wall of the vessel body 1. The scraper 12 includes a vertical part 121, an arc-shaped part 122 and a connecting part 123. The connecting part 123 is fixedly installed on one side of the bottom end of the vertical shaft 6. The arc-shaped part 122 is fixedly connected to one end of the connecting part 123. The arc-shaped part 122 slides in contact with the bottom inner wall of the vessel body 1. The vertical part 121 is fixedly connected to one side of the arc-shaped part 122. The vertical part 121 slides in contact with the inner side wall of the vessel body 1. The vertical part 121, the arc-shaped part 122 and the connecting part 123 are integrally formed.

[0035] With the above structure, when the high-efficiency premixing kettle for pesticide production provided in this application is in use, the vertical shaft 6 will drive the scraper 12 to rotate. The vertical part 121 can scrape off the raw materials adhering to the inner wall of the kettle body 1, and the arc-shaped part 122 can scrape off the raw materials adhering to the bottom inner wall of the kettle body 1. Thus, the raw materials adhering to the inner wall of the kettle body 1 can be scraped off from all directions, avoiding waste of raw materials, ensuring full utilization of the raw materials in the kettle body 1, and also helping to keep the inside of the kettle body 1 clean and reduce interference with subsequent production processes.
