Description

Technical Field

[0001] The present invention relates to the technical field of suspension concentrate production, in particular to a dispersing device and a dispersing method for producing pesticide suspension concentrate. Background Art

[0002] A pesticide suspension concentrate is a suspension obtained by finely grinding a water-insoluble solid pesticide and an adjuvant and uniformly dispersing them in an aqueous medium. During the production of the suspension concentrate, a dispersing device is required to disperse the solid pesticide. For example, the patent application number 202420231871.3 proposes a dispersing device for suspension concentrate production, which comprises a tank body and a dispersing component for dispersing the suspension concentrate in the tank body. The dispersing component comprises a vertical shaft, a motor and a dispersing tool. A conical cover with a small top and a large bottom is installed inside the tank body. The conical cover can be raised and lowered along the inner wall of the tank body. An opening for the vertical shaft to pass through is provided at the top of the conical cover. An annular drainage groove with a notch facing downward is provided on the inner wall near its lower end of the conical cover, which is used to introduce the suspension concentrate rising from the inner wall of the tank body into the interior. Several toothed dispersing blades distributed along its circumference are fixedly connected to the groove surface of the annular drainage groove, which are used to disperse the suspension concentrate introduced into the annular drainage groove. The above solution can guide the suspending agent that surges at the edge due to centrifugal force into the interior of the annular drainage groove, continuously colliding with the toothed dispersing blades on the groove surface, and the toothed dispersing blades disperse the suspending agent, thereby ensuring the dispersion effect.

[0003] During use, existing dispersion devices require a long time for some larger solid particles to merge with the liquid, which reduces processing efficiency. Moreover, large solid particles are more likely to settle at the bottom, resulting in uneven mixing. Therefore, improvements are made to this problem, and a dispersion device and dispersion method for the production of pesticide suspensions are proposed. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a dispersion device and dispersion method for the production of pesticide suspensions, which solves the problem that during the use of the dispersion device, some larger solid particles take a long time to merge with the liquid, reducing processing efficiency. Moreover, large solid particles are more likely to settle at the bottom, resulting in uneven mixing.

[0012] Preferably, a plurality of annular through grooves are evenly distributed on the inner wall of the bottom of the conical material guide barrel, and the annular through grooves are arranged above the annular material conveying plate. A rotating rod is fixedly installed at the center of the lower surface of the conical rotating column.

[0013] Preferably, one end of the rotating rod passes through the bottom of the conical material guide barrel and the end is rotatably set on the bottom inner wall of the barrel body. The rotating rod is located inside the barrel body and has several first stirring rods evenly distributed on the rod body, and each of the first stirring rods is installed with several second stirring rods on the upper and lower surfaces.

[0014] A method for using a dispersing device for producing a pesticide suspension concentrate comprises the following steps: S1: Add raw materials, put the solid pesticide into the conical material guide barrel, and then add the reaction solvent into the barrel through the liquid addition port; S2: Raw materials are crushed. The drive motor is started to control the conical guide barrel and the conical rotating column to rotate.

When the material is crushed and ground, the material will be gradually ground into small particles. Large particles of material will fall down only after being ground into a certain size, which can effectively shorten the time required for mixing with the liquid, improve processing efficiency, and prevent large particles from falling directly into the barrel body, resulting in better use effect.

[0016] 2. When the conical rotating column rotates, it will drive the rotating rod at the bottom to rotate, so that the first stirring rod and the second stirring rod will rotate accordingly, which can fully mix the fixed particles with the liquid inside the barrel. Driven by the driving motor, it can simultaneously complete the crushing and grinding of solid materials and the mixing with the liquid, which can effectively save energy consumption and reduce processing costs.

[0021] like Figures 2 to 6 As shown, the crushing and stirring mechanism 3 includes a support frame 301, the support frame 301 is installed on one side of the outer surface of the barrel body 1, a top plate 302 is installed on the top of the support frame 301, a driving motor 303 is installed on the upper surface of the top plate 302, a transmission gear 304 is installed on the output end of the driving motor 303 and below the top plate 302, a mounting rod 305 is rotatably installed on one side of the lower surface of the top plate 302, and a conical rotating column 306 is installed at one end of the mounting rod 305, and the conical rotating column 306 is arranged on the conical guide barrel. 2, a plurality of grinding blades 308 are provided on the outer surface of the conical rotating column 306 and the inner wall of the conical material guide barrel 2. A first annular plate 201 is installed on the upper surface of the conical material guide barrel 2, and a first ring gear 202 is installed on the inner wall of the first annular plate 201. A second annular plate 307 is installed on the outer side of the upper surface of the conical rotating column 306, and a second ring gear 3071 is installed on the outer surface of the second annular plate 307. The two sides of the transmission gear 304 are respectively engaged with the first ring gear 202 and the second ring gear 3071.

[0022] Through the meshing transmission between the transmission gear 304 and the first gear ring 202 and the second gear ring 3071, under the drive of the drive motor 303, the conical material guide barrel 2 and the conical rotating column 306 can be controlled to rotate in opposite directions, so that the grinding blade 308 can crush and grind the material faster. The distance between the conical material guide barrel 2 and the conical rotating column 306 gradually shortens from top to bottom, and the material can be gradually ground into small particles. Large particles of material will only fall down after being ground into a certain size. Therefore, no large-volume particles will appear inside the barrel body 1, so that the time required for mixing with the liquid will be shorter.

[0023] like Figure 5 、 Figure 7 、 Figure 8 As shown, the outer surface of the conical guide barrel 2 is installed with a first limit block 203, a support side plate 3011 is installed on the side surface of the support frame 301, and a first limit groove 3012 that cooperates with the first limit block 203 is provided on one end surface of the support side plate 3011. The lower surface of the conical guide barrel 2 is provided with a second limit block 204, and the upper surface of the annular conveying plate 6 is provided with a second limit groove 601 that cooperates with the second limit block 204. The inner wall of the bottom of the conical guide barrel 2 is evenly distributed with There are annular through grooves 310, which are arranged above the annular conveying plate 6. A rotating rod 309 is fixedly installed at the center of the lower surface of the conical rotating column 306.

The first stirring rod 311 and the second stirring rod 312 are set in different directions, and have a larger stirring range during the rotation process, thereby having a better stirring effect.

[0025] A method for using a dispersing device for producing a pesticide suspension concentrate comprises the following steps: S1: Adding raw materials: Place the solid pesticide into the conical material guide barrel 2, and then add the reaction solvent into the barrel body 1 through the liquid addition port 4; S2: The raw materials are crushed. The drive motor 303 is started to control the conical guide barrel 2 and the conical rotating column 306 to rotate. The grinding blades 308 crush the fixed pesticides, and the crushed pesticides fall into the interior of the barrel 1 through the annular groove 310; S3: Dispersion and mixing: The crushed solid pesticide is evenly dispersed into the interior of the reaction solvent through the rotation of the first stirring rod 311 and the second stirring rod 312; S4: Discharging; after the solid pesticide and the solvent are dispersed and mixed, they are discharged to the outside through the liquid outlet 5.

[0026] The working principle of the dispersion device and dispersion method for producing pesticide suspension concentrate: During use, liquid is added to the interior of the barrel body 1 through the liquid filling port 4, solid materials are added to the top of the conical guide barrel 2, and the transmission gear 304 is driven to rotate by the driving motor 303. Under the meshing action between the transmission gear 304 and the first gear ring 202 and the second gear ring 3071, the first annular plate 201 and the second annular plate 307 respectively drive the conical guide barrel 2 and the conical rotating column 306 to rotate in opposite directions. During the rotation, the grinding blade 308 grinds the fixed particles. By utilizing the shape and position of the conical guide barrel 2 and the conical rotating column 306, the distance between the inner wall of the conical guide barrel 2 and the outer wall of the conical rotating column 306 becomes smaller and smaller from top to bottom. When the material is crushed and ground, The material will be gradually ground into small particles, which can effectively shorten the time required for mixing with the liquid, improve processing efficiency, and will not cause larger particles to fall directly to the bottom, resulting in better use effect. The ground small particles will fall into the interior of the barrel body 1 through the annular groove 310 to mix with the liquid. The conical rotating column 306 will drive the rotating rod 309 at the bottom to rotate when rotating, so that the first stirring rod 311 and the second stirring rod 312 will rotate accordingly, and the fixed particles can be fully mixed with the liquid inside the barrel body 1. After the mixing is completed, it can be discharged through the liquid outlet 5.
