Description

Technical Field

[0001] This utility model belongs to the field of water suspension production and mixing technology, specifically a water suspension production and mixing device. Background Technology

[0002] Aqueous suspensions of pesticides refer to multiphase dispersion systems formed by dispersing water-insoluble solid active ingredients in water through certain mechanical means. Aqueous suspensions appear as opaque suspensions, with dispersed phase particle sizes generally ranging from 0.5 to 5 μm and an average particle size of 2 to 3 μm. Aqueous suspensions belong to multiphase coarse dispersion systems. Any pesticide that can remain stable in water for a long time without decomposition, and is insoluble or slightly soluble in water, can be formulated into aqueous suspensions. Compared with traditional formulations, aqueous suspensions of pesticides have the following advantages: no dust hazard; using water as the dispersion medium, there are no flammability or phytotoxicity issues caused by organic solvents; high specific gravity and small packaging volume; good dispersibility and adhesion, high suspension rate, strong adhesion to plant surfaces, and resistance to rain washout, resulting in more significant and longer-lasting efficacy than wettable powders; small particle size, large active surface area, strong penetration, low cost, and high efficacy. Therefore, aqueous suspensions are relatively safe and environmentally friendly compared to other pesticide formulations, and have become a relatively large-tonnage pesticide variety among new water-based pesticide formulations.

[0003] Existing water suspension production mixing equipment involves directly placing the active ingredient and water into a mixing tank, and then stirring the water and active ingredient in the mixing tank. Since the active ingredient is generally in powder form, the mixing process between the active ingredient and water in the mixing tank is slow, requiring a long stirring time to achieve a usable effect.

[0004] Therefore, a water suspension production mixing device is proposed to address the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] Please see Figures 1-5 This utility model provides a mixing device for producing an aqueous suspension agent, including a first mixing tank 1. A first motor 2 is fixedly installed on the top of the first mixing tank 1. A stirring rod 22 is fixedly connected to the output shaft of the first motor 2. A first valve 34 is fixedly installed on the top of the first mixing tank 1. A second mixing tank 3 is fixedly connected to the top of the first valve 34. A second motor 31 is fixedly installed on the top of the second mixing tank 3. A second connecting shaft 32 is fixedly connected to the output shaft of the second motor 31. A stirring frame 33 is fixedly connected to the outer surface of the second connecting shaft 32. A viewing window 35 is fixedly installed on the outer surface of the second mixing tank 3.

[0019] Existing water suspension production mixing equipment involves directly placing the active ingredient and water into a mixing tank, and then stirring the water and active ingredient in the mixing tank. Since the active ingredient is generally in powder form, the mixing process between the active ingredient and water in the mixing tank is slow, requiring a long stirring time to achieve a usable effect.

[0020] In use, the raw material is first poured into the inner cavity of the second mixing tank 3, and then water is added to the inner cavity of the second mixing tank 3. Then, the output shaft of the second motor 31 drives the second connecting shaft 32 to rotate, and the second connecting shaft 32 further drives the stirring frame 33 to rotate. Since the internal space of the second mixing tank 3 is small, there is not much water in the inner cavity of the second mixing tank 3. This allows the second motor 31 to drive the second connecting shaft 32 and the stirring frame 33 to rotate at high speed to break up the clumps of powdered raw material and stir the raw material and water. The stirring effect can be observed through the viewing window 35. At this time, the concentration of the mixed liquid is relatively high. By opening the first valve 34, the mixed liquid in the inner cavity of the viewing window 35 enters the inner cavity of the first mixing tank 1 to dilute and stir the mixed liquid. This can accelerate the mixing of the mixed liquid and water, thereby improving the production efficiency of the water suspension.

[0021] Furthermore, such as Figure 2 As shown, the output shaft of the first motor 2 is fixedly connected to the first connecting shaft 21, the stirring rod 22 is fixedly installed on the outer surface of the first connecting shaft 21, and one end of the stirring rod 22 is fixedly connected to the first scraper 23. The first scraper 23 is slidably installed on the inner wall of the first mixing box 1. A second scraper 25 is fixedly connected to the bottom of the first connecting shaft 21. The second scraper 25 is slidably installed on the bottom wall of the first mixing tank 1. A baffle 24 is fixedly installed on the outer surface of the first connecting shaft 21.

[0022] In use, the first motor 2 drives the first connecting shaft 21 to rotate via its output shaft. The first connecting shaft 21 drives the stirring rod 22 to rotate, which stirs the aqueous suspension. The stirring rod 22 drives the first scraper 23 to rotate, and the first connecting shaft 21 drives the second scraper 25 to rotate, which scrapes the inner wall of the first mixing tank 1, preventing the raw material in the aqueous suspension from sticking to the inner wall of the first mixing tank 1 and making it difficult to clean. The first connecting shaft 21 drives the baffle 24 to rotate, which causes the raw material in the inner cavity of the first mixing tank 1 to flow upward or downward, further improving the stirring efficiency.

[0023] Furthermore, such as Figure 4 As shown, a clean water tank 413 and a water pump 4 are fixedly installed on the top of the first mixing tank 1, and a first water inlet pipe 41 and a first water outlet pipe 42 are fixedly connected to both sides of the water pump 4 respectively. The top of the first water outlet pipe 42 is fixedly installed with a second water outlet pipe 421 and a third water outlet pipe 422. One end of the second water outlet pipe 421 passes through the inner cavity of the second mixing box 3, and one end of the third water outlet pipe 422 passes through the inner cavity of the first mixing box 1 and is fixedly connected with a water hose 4221. Several nozzles 4222 are fixedly installed at the bottom of the water hose 4221. A second water inlet pipe 411 and a third water inlet pipe 412 are fixedly connected to one side of the first water inlet pipe 41. One end of the third water inlet pipe 412 extends into the inner cavity of the clean water tank 413, and the other end of the third water inlet pipe 412 extends into the inner cavity of the first mixing tank 1. A second valve 43 is fixedly installed on the outer surface of the second water inlet pipe 411, the third water inlet pipe 412, the second water outlet pipe 421, and the third water outlet pipe 422.

[0024] In use, this utility model can control the water pump 4 to draw water from the inner cavity of the first mixing tank 1 or the clean water tank 413 by opening and closing the second valve 43 at different positions. It can also control the water pump 4 to deliver water to the inner cavity of the second mixing tank 3 or the first mixing tank 1. By opening the second valve 43 on the outer surface of the third inlet pipe 412 and the second outlet pipe 421, clean water can be delivered to the inner cavity of the second mixing tank 3 to clean the inner cavity of the second mixing tank 3. By opening the second valve 43 on the outer surface of the third inlet pipe 412 and the third outlet pipe 422, clean water can enter the inner cavity of the water belt 4221 and be sprayed out from the nozzle 4222 to clean the inner wall of the first mixing tank 1. By opening the second valve 43 on the outer surface of the second inlet pipe 411 and the second outlet pipe 421, water in the inner cavity of the first mixing tank 1 can be drawn into the inner cavity of the second mixing tank 3, which avoids the original medicine not being able to mix completely with the water due to insufficient water in the inner cavity of the second mixing tank 3, and also avoids changes in the concentration of the water suspension caused by drawing water from the outside.

[0025] Working principle: When using this utility model, the raw material is first placed in the inner cavity of the second mixing tank 3. Then, the second valve 43 on the outer surface of the second water inlet pipe 411 and the second water outlet pipe 421 is opened, and the water pump 4 is started to draw water from the inner cavity of the first mixing tank 1 into the inner cavity of the second mixing tank 3. Then, the output shaft of the second motor 31 drives the second connecting shaft 32 and the stirring frame 33 to stir the raw material and water. After stirring is completed, the first valve 34 is opened to input the mixed liquid in the inner cavity of the second mixing tank 3 into the inner cavity of the first mixing tank 1. Then, the output shaft of the first motor 2 drives the first connecting shaft 21 to rotate. The first connecting shaft 21 drives the stirring rod 22, the first scraper 23, the baffle 24 and the second scraper 25 to rotate, so that the first scraper 23 and the second scraper 25 scrape the inner wall of the first mixing tank 1 respectively. The baffle 24 and the stirring rod 22 stir the water and the mixed liquid in the inner cavity of the first mixing tank 1.

[0026] After mixing, the inner walls of the first mixing tank 1 and the second mixing tank 3 need to be cleaned. By opening the second valve 43 on the outer surface of the third water inlet pipe 412, the second water outlet pipe 421 and the third water outlet pipe 422, the clean water in the inner cavity of the clean water tank 413 can flow into the inner cavities of the second mixing tank 3 and the first mixing tank 1 respectively, and clean the inner walls of the first mixing tank 1 and the second mixing tank 3 respectively. The clean water flowing into the inner cavity of the third water outlet pipe 422 first passes through the water belt 4221 and then is sprayed out through the nozzle 4222 to clean the inner wall of the first mixing tank 1.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
