Description
Technical Field
[0001] The utility model belongs to the technical field of water suspension production, and specifically relates to a mixing device for water suspension production. Background Art
[0002] Pesticide aqueous suspension refers to a multiphase dispersion system formed by dispersing water-insoluble solid raw materials in water by certain mechanical means. The appearance of the aqueous suspension is an opaque suspension, and the particle size of the dispersed phase is generally 0.5-5μm, and the average particle size is 2-3μm. The aqueous suspension belongs to a multiphase coarse dispersion system. Any pesticide that can be stable in water for a long time without decomposition, insoluble in water or slightly soluble in water can be made into an aqueous suspension. Compared with traditional formulations, pesticide aqueous suspensions have the following advantages: no dust hazard; water is used as the dispersion medium, and there is no flammability and pesticide damage caused by organic solvents; high specific gravity and small packaging volume; the suspension has good dispersibility and adhesion, high suspension rate, strong ability to adhere to the surface of plants, and resistance to rain erosion, so the efficacy is more significant and more lasting than wettable powders; it has small particles, large active surface, strong permeability, low cost and high efficacy. Therefore, compared with other pesticide formulations, aqueous suspensions are safe and environmentally friendly, and have become a pesticide variety with a larger tonnage among new water-based pesticide formulations.
[0003] During the production process of water suspension concentrate, the water suspension concentrate needs to be stirred and mixed by equipment such as a mixing tank. However, the stirring mechanism inside the existing mixing tank is generally set in the middle. When it stirs the liquid inside the tank, it is not easy to stir the sediment at the bottom of the tank, especially the sediment settled at the edge of the bottom of the tank. It cannot be fully dissolved, resulting in an imbalance in the ratio of the finished pesticide water suspension concentrate, affecting the quality of the finished pesticide water suspension concentrate. For this reason, we propose a mixing and dispensing equipment for the production of water suspension concentrate. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figures 1 - 4 The utility model provides a mixing and dispensing device for producing water suspension, comprising a dispensing tank 1 and a servo motor 2, wherein the servo motor 2 is arranged on the upper surface of the dispensing tank 1, a stirring mechanism 3 is arranged inside the dispensing tank 1, the stirring mechanism 3 comprises a first rotating shaft 301, and the upper end of the first rotating shaft 301 is transmission-connected with the power output end of the servo motor 2 through a coupling, a rotating gear 302 is arranged on the circumferential surface of the upper end of the first rotating shaft 301, a transmission gear 303 is arranged on the side wall of the rotating gear 302, and three transmission gears 303 are arranged, a second rotating shaft 305 is arranged in the middle of the three transmission gears 303, a first stirring rod 306 is arranged on the circumferential surface of the upper end of the first rotating shaft 301 and the three second rotating shafts 305, and four groups of first stirring rods 306 do not intersect with each other. The arrangement of the four groups of first stirring rods 306 can prevent them from colliding with each other during rotation. At the same time, the water suspension inside the preparation tank 1 is stirred more violently, thereby improving the mixing efficiency of the water suspension. The circumferential surfaces of the lower ends of the first rotating shaft 301 and the three second rotating shafts 305 are all provided with second stirring rods 307, and the lower surfaces of the second stirring rods 307 are provided with rubber scrapers 308. The arrangement of the rubber scrapers 308 can scrape up the sediment at the bottom of the preparation tank 1 and mix it with the water flow when the stirring rods are stirred. More importantly, it can scrape the bottom edge of the preparation tank 1, thereby avoiding the problem that the bottom edge of the existing device is not easily stirred up by the water flow, thereby making the water suspension mixed more evenly and making the quality of the finished water suspension more stable.
[0021] In this embodiment, preferably, three transmission gears 303 are arranged in a circumferential array on the circumferential surface of the rotating gear 302 and are meshed and connected to the rotating gear 302. An internal tooth ring 304 is fixedly installed on the upper inner wall of the dispensing tank 1. The three transmission gears 303 are all meshed and connected to the inner wall of the tooth ring 304. The setting that the tooth ring 304 is fixedly installed inside the dispensing tank 1 enables the three transmission gears 303 to rotate around the rotating gear 302 while rotating on their own axes when the rotating gear 302 drives the three transmission gears 303 to rotate. Then, the three transmission gears 303 can drive the three second rotating shafts 305 to rotate on their own axes and rotate around the rotating gear 302. An annular rotating groove 7 is formed in the inner top wall of the dispensing tank 1. The upper ends of the three second rotating shafts 305 are all movably installed inside the annular rotating groove 7. The setting of the annular rotating groove 7 can limit the upper ends of the second rotating shafts 305 while not affecting the rotation of the second rotating shafts 305, enabling the second rotating shafts 305 to rotate smoothly on their own axes and rotate around the rotating gear 302. Inside the lower ends of the three second rotating shafts 305, balls 6 are rotatably installed, and the lower ends of the balls 6 are abutted against the inner bottom wall of the dispensing tank 1. The setting of the balls 6 enables the lower ends of the second rotating shafts 305 to be abutted against the inner bottom of the dispensing tank 1 through the balls 6 while not affecting the rotation of the second rotating shafts 305. The lower end of the first rotating shaft 301 is rotatably installed on the inner bottom wall of the dispensing tank 1. A fixing plate 5 is arranged on the upper inner wall of the dispensing tank 1, and the fixing plate 5 is arranged below the rotating gear 302. An annular rotating plate 4 is rotatably installed inside the fixing plate 5. The upper ends of the first rotating shaft 301 and the three second rotating shafts 305 are all rotatably installed inside the annular rotating plate 4. The setting of the annular rotating plate 4 enables the annular rotating plate 4 to rotate inside the fixing plate 5 when the second rotating shafts 305 rotate, and the fixing plate 5 and the annular rotating plate 4 can block the water suspension agent below, preventing the splashed liquid from adhering to the surfaces of the rotating gear 302 and the transmission gears 303 when the water suspension agent is stirred and mixed, thus avoiding rusting of the rotating gear 302 and the transmission gears 303 and improving the service effect of the rotating gear 302 and the transmission gears 303. An inlet 8 is formed in the upper end of the left side wall of the dispensing tank 1, and the inlet 8 is arranged below the fixing plate 5. The setting of the inlet 8 facilitates the addition of the water suspension agent raw material into the dispensing tank 1 through the inlet 8. An outlet 9 is formed in the lower end of the left side wall of the dispensing tank 1, and a valve is arranged inside the outlet 9. The setting of the outlet 9 enables the valve at the outlet 9 to be opened after the water suspension agent inside the dispensing tank 1 is dispensed, and the finished water suspension agent can be collected at the outlet 9.
[0022] Working principle and usage process of the present utility model: When preparing and mixing the aqueous suspension concentrate, first send the raw materials of the aqueous suspension concentrate into the interior of the preparation tank 1 through the feed inlet 8. Then connect the servo motor 2 to an external power source and start the servo motor 2. The servo motor 2 drives the first rotating shaft 301 and the rotating gear 302 to rotate. The rotation of the rotating gear 302 drives the rotation of three transmission gears 303, so that the three transmission gears 303 rotate self and rotate around the rotating gear 302 under the cooperation of the tooth ring 304. The rotation of the three transmission gears 303 drives the rotation of three second rotating shafts 305. The rotation of the first rotating shaft 301 and the three second rotating shafts 305 drives the rotation of the first stirring rod 306 and the second stirring rod 307. The rotation of the first stirring rod 306 stirs the aqueous suspension concentrate, and the rotation of the second stirring rod 307 drives the rotation of the rubber scraping plate 308, thereby scraping up the sediment at the bottom of the preparation tank 1, and then uniformly mixing it in the aqueous suspension concentrate under the flow of water, avoiding the sediment at the bottom of the preparation tank 1 from affecting the quality of the finished aqueous suspension concentrate. After the preparation of the aqueous suspension concentrate is completed, open the valve and collect the finished aqueous suspension concentrate at the discharge port 9.
[0023] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
