Description

Technical Field

[0001] The utility model relates to the technical field of suspension agent production, in particular to a suspension agent production mixing device. Background Art

[0002] Suspension concentrate refers to a preparation in which solid pesticide technical is evenly dispersed in water in particles of less than four microns. Since suspension concentrate does not have the dust problem of wettable powder, is non-flammable and non-explosive, has a small particle size, high biological activity, a large specific gravity, and a small packaging volume, it is safe and environmentally friendly compared to other pesticide formulations. Therefore, suspension concentrate has become the type of pesticide with the largest tonnage among new water-based pesticide formulations. It is divided into two types: water suspension concentrate and oil suspension concentrate. Water suspension concentrate uses water as the solvent, while oil suspension concentrate uses oil as the main solvent and does not contain water. Commonly used oils are vegetable oils, such as corn oil, rapeseed oil, etc., and artificially synthesized oils can also be used. In the production process of suspension concentrate, a mixing device is usually required to stir and mix the suspension concentrate raw materials.

[0003] As disclosed in a Chinese patent: A high-efficiency mixing device for the production of pesticide suspensions, application number: CN202220451074.7, comprising a kettle body, electric cylinders are symmetrically installed on both sides of the center of the top plate of the kettle body, the extended ends of the electric cylinders are vertically upward, and the ends are fixedly connected to a mounting plate; a motor is fixedly connected to the center of the bottom plate of the mounting plate, and a stirring shaft is fixedly connected to the output end of the motor, and the stirring shaft is slidably inserted on the top plate of the kettle body, and the lower part is located in the kettle body; a stirring mechanism is symmetrically connected to the lower part of the stirring shaft, and the stirring mechanism includes a cross bar fixedly connected to the stirring mechanism, and a plurality of stirring blades are rotatably installed on the cross bar; a control panel is installed on the outer wall of the kettle body. The utility model has a simple structure and a reasonable design. Through the setting of the device, the electric cylinder drives the motor to move up and down, thereby driving the stirring mechanism to move up and down. While the stirring mechanism is stirring, the stirring blades rotate, the stirring effect is good, the materials are fully mixed, the stirring efficiency is high, and the product quality is guaranteed.

[0004] However, in the above technical scheme, with the rapid development of society and technology, people have higher and higher requirements for mixing devices. Suspension concentrate is a liquid preparation in which pesticides are mixed with suspending agents, dispersants and other auxiliary agents to form particles suspended in water. Therefore, the size distribution of particles in the suspension concentrate has an important influence on its efficacy and particles. The current mixing device only has a stirring function and cannot separate and classify the suspension concentrate according to the size of the particles. If the particle size distribution in the suspension concentrate is relatively uneven, it will affect the suspension of the device and the efficiency of drug release. Utility Model Content

[0024] like Figure 3 and Figure 4 As shown, in another embodiment of the present invention, the spiral centrifuge 3 includes a spiral centrifuge body 301, and the spiral centrifuge body 301 is provided with a plurality of second discharge ports 302 and second feed ports 303;

[0025] A support plate 304 is provided in the second feed port 303, a guide cylinder 305 is provided on the support plate 304, a closing block 306 is provided on one side above the guide cylinder 305, a guide slot 307 is provided in the closing block 306, a telescopic rod 308 is provided in the guide slot 307, a plurality of sealing layers 309 are provided on the inner wall of the guide slot 307, when the suspension agent needs to be separated and classified according to the particle size of the suspension agent, the telescopic rod 308 is first started, the telescopic rod 308 is contracted, and the closing block 306 is moved toward the guide cylinder 305 along the trajectory of the guide slot 307 by using the telescopic rod 308, so that the closing block 306 gradually leaves the second feed port 303. The first discharge port 6 is then sealed by the sealing block 306, and the suspension in the inner cavity of the mixing barrel 2 enters the second feed port 303 through the first discharge port 6, and then enters the spiral centrifuge body 301 through the second feed port 303. The spiral centrifuge body 301 separates and classifies the suspension according to the particle size of the suspension, and then discharges the suspensions of different particle sizes from different second discharge ports 302, so that the particle size of the suspension is more uniform, and the efficacy and stability are improved. After the separation is completed, the sealing block 306 re-enters the first discharge port 6 to seal the first discharge port 6, and then the above operation is repeated.

[0026] The working principle of this suspension production mixing device:

[0027] When in use, first move the baffle 10 to open the first feed port 9, then pour the suspension agent raw material into the mixing barrel 2 through the first feed port 9, then move the baffle 10 again to close the first feed port 9, and then start the motor 5 to drive the mixing and stirring paddle 4 to rotate, and use the mixing and stirring paddle 4 to stir and mix the suspension agent raw material. After the stirring is completed, start the telescopic rod 308, and use the telescopic rod 308 to make the closing block 306 gradually leave the first discharge port 6, and the suspension agent in the inner cavity of the mixing barrel 2 enters the second feed port 303 through the first discharge port 6. Then, the suspension enters the spiral centrifuge body 301 through the second feed port 303, and the vortex generator 8 is started at the same time. The vortex generator 8 forms a vortex inside the suspension, which speeds up the suspension entering the spiral centrifuge body 301. The vortex can also prevent local precipitation inside the suspension. Then, the spiral centrifuge body 301 separates and classifies the suspension according to the particle size of the suspension, and then discharges the suspensions of different particle sizes from different second discharge ports 302, so that the particle size of the suspension is more uniform, thereby improving the efficacy and stability.
