Description

Technical Field

[0001] This invention belongs to the field of mixers and relates to a mixing device and its application in a production line for compounding difenoconazole and pyraclostrobin. Background Technology

[0002] Mixers are primarily used to mix, disperse, and homogenize materials, covering a wide range of fields and adapting to the processing needs of different material forms. For example, in the chemical and new materials industries, mixers are used in pesticide production for mixing and dispersing raw materials for pesticide emulsifiable concentrates and suspensions, ensuring uniform distribution of active ingredients and improving efficacy. The preparation of suspensions typically requires a disperser, whose core function is to evenly disperse solid particles in a liquid, forming a stable suspension system. For industrial production and laboratory settings, the most commonly used mixing equipment for pesticide suspension production is the basket mill-dispersant integrated machine.

[0003] The main structural components of a basket mill and dispersion machine include: a load-bearing and lifting mechanism, a transmission system, a dispersion component, and a grinding component, such as the improved basket mill for coatings disclosed in Chinese Utility Model Patent No. CN204602328U and the basket mill disclosed in Chinese Utility Model Patent No. CN203663925U. Existing basket mills still have some problems in actual production applications. For example, after the grinding basket is removed from the container, the container is usually moved away from the mill, and the residual solution in the grinding basket will fall to the ground. This will affect the workshop environment, and some harmful odors and gases may cause discomfort to workers. Furthermore, the range of motion of the grinding balls inside the grinding basket is limited. Most grinding balls only generate multi-directional collisions and friction under the action of the lever, and the probability of collision and friction is also affected by the filling volume of the grinding balls. The actual probability of collision and friction needs to be improved, especially when the basket is deep and the grinding balls are numerous; otherwise, it will directly affect the shearing effect on the suspended material.

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Examples, such as Figures 1-14As shown, the present invention provides a mixing device, including a base 1, on which a hydraulic lifting device 2 and a hydraulic station 3 are provided. The lifting end of the hydraulic lifting device 2 faces upward and is provided with a transmission box 4. A drive motor 5 is provided at the bottom of one end of the transmission box 4, and a basket grinding mechanism 6 is provided at the other end of the transmission box 4. The basket grinding mechanism 6 includes a connecting seat 61 and a main shaft 62 located at the center of the connecting seat 61. A dispersing component 63, a grinding component 64, and a lever 65 located inside the grinding component 64 are provided on the main shaft 62. The dispersing component 63 includes a dispersing disc, and dispersing blades are provided on both the upper and lower edges of the dispersing disc. The dispersing blades make the material flow more turbulently in the container and improve the grinding efficiency. A long rod bolt 66 connecting the grinding component 64 and the connecting seat 61 is provided on the top of the grinding component 64. The grinding component 64 includes a basket body 641, a cover plate 642, and a bottom drain plate 643 for seeping liquid. The inside of the basket body 641 is filled with grinding media, such as zirconium beads 684. Hydraulic station 3 provides hydraulic power to hydraulic lifting device 2. Hydraulic lifting device 2 controls the height of transmission box 4 and basket grinding mechanism 6 through lifting action. Container containing material moves to the bottom of basket grinding mechanism 6. Basket grinding mechanism 6 extends into the container to be stirred to complete stirring, mixing and grinding of material, and finally obtains the corresponding dispersion system, i.e. suspension agent. Guide rods connected to transmission box 4 are provided on the outside of hydraulic lifting device 2 to ensure the balance of transmission box 4 when lifting action.

[0021] Based on this, the inner wall of the basket 641 provided by the present invention is provided with a peristaltic wall sleeve 67, which is used to promote the movement of the grinding body inside the basket 641. The axial surface of the main shaft 62 is provided with at least one set of triple spiral grooves 621 extending along its length direction. The triple spiral grooves 621 include three parallel spiral grooves and a grinding belt 68 is provided in the spiral grooves. The grinding belt 68 has a groove-shaped structure and its groove opening faces away from the center of the main shaft 62. A purification device 7 is provided on the outside of the transmission box 4 in a semi-enclosed manner. A residual liquid recovery device 8 with an opening and closing function is provided on the outside of the purification device 7. The residual liquid recovery device 8 realizes the recovery of residual liquid through the motorized opening and closing basket grinding mechanism 6.

[0022] Specifically, the main shaft 62 simultaneously drives the lever 65 and the dispersing component 63 to rotate continuously. As the lever 65 rotates, it causes the grinding media to move irregularly within the basket 641. The continuous rotation of the peristaltic sleeve 67, in conjunction with the lever 65, changes the direction of motion of the grinding media contacting the peristaltic sleeve 67, effectively promoting the movement of the grinding media within the basket 641 and increasing the collision and friction frequency of the grinding media, which is beneficial for improving the shearing performance and grinding quality of the material. Furthermore, the parallel distribution of the triple spiral grooves 621 increases the torque and flow rate of the material entering each spiral groove. In addition to entering the basket 641 under the pressure generated by the dispersing component 63, the fluid can also form a mixed flow through the triple spiral grooves 621, improving the mixing performance of the material and promoting its entry into the basket 641 for grinding. Simultaneously, the grinding belt 68 in the triple spiral grooves 621 can directly contact the material, playing a role in pre-grinding the material, thereby improving the efficiency of this equipment in preparing suspension dispersion systems.

[0023] In terms of environmental protection, the purification device 7 provided by this invention can rise and fall with the transmission box 4. When the basket grinding mechanism 6 descends into the container, the top of the grinding component 64 can act as a sealing cap for the container, forming a closed condition with the top of the container. During the stirring and mixing process, the container remains sealed and no gas overflows from the basket grinding mechanism 6. As the basket grinding mechanism 6 gradually leaves the container with the rise of the transmission box 4, the purification device 7 can be activated to extract the overflowing gas from the open atmosphere. The purification unit 72 built into the purification device 7 purifies the gas and then discharges it through the through hole reserved at the tail of the purification device 7, thereby achieving the purpose of purifying the gas. This is beneficial to improving the spatial environment of the workshop and to the health of the workers.

[0024] Furthermore, the residual liquid recovery device 8 can also rise and fall with the transmission box 4. While the basket grinding mechanism 6 performs its stirring and mixing function, the residual liquid recovery device 8 opens to avoid the container containing the material. After the basket grinding mechanism 6 rises until its lowest level is above the top of the container, the residual liquid recovery device 8 closes to complete the enclosure of the basket grinding mechanism 6. The entire volume of the basket grinding mechanism 6 is within the enclosure of the residual liquid recovery device 8. The liquid remaining in the part of the basket grinding mechanism 6 that has been immersed falls into the residual liquid recovery device 8 due to gravity. The residual liquid recovery device 8 provides an effective recovery path for the residual liquid until it enters the recovery container. In this way, the present invention can effectively improve the environment around the equipment from both gas and liquid perspectives, which is conducive to improving the environmental protection of workshop production operations.

[0025] To improve the production efficiency of the dispersion system, the peristaltic wall sleeve 67 provided by the present invention includes a flexible wall sleeve body 671. The wall sleeve body 671 has multiple vertically spaced curved annular protrusions 672 on its sidewall facing the center of the basket 641. The inner side of the curved annular protrusions 672 is filled with peristaltic fluid 673 and peristaltic balls 674. The bottom of the wall sleeve body 671 is provided with a filling nozzle and a plug for filling the peristaltic fluid 673 and peristaltic balls 674. The outer peripheral surface of the wall sleeve body 671 is tightly fitted with the inner wall of the basket 641. Its interior is filled with peristaltic fluid 673 and peristaltic balls 674, causing the curved annular protrusions 672 to form an effective undulating surface inside the basket 641. The peristaltic fluid 673 provides a certain amount of lubrication for the peristaltic balls 674, allowing the peristaltic balls 674 to be subjected to... After extrusion, the floating surface of the curved annular protrusion 672 can be changed in real time. In this way, the lever 65 rotates with the main shaft 62 to move the grinding body. The movement range of the grinding body partially overlaps with the minimum radial range of the curved annular protrusion 672. The movement of the grinding body can cause extrusion on the curved annular protrusion 672. The peristaltic ball 674 is extruded and generates corresponding activity, which in turn reacts on the grinding body to enrich the movement path of the grinding body, improve the grinding and shearing efficiency of the grinding body on the material, and thus improve the production efficiency of the dispersion system.

[0026] like Figure 10 , Figure 11 and Figure 12 The wall sleeve 671 provided by the present invention is provided with multiple inner connecting pipes 675 that are spaced apart from the curved annular protrusions 672. The center of the inner connecting pipe 675 is provided with a connecting hole. A fixing ring 676 is provided between adjacent curved annular protrusions 672. The fixing ring 676, the wall sleeve 671 and the basket 641 are connected by screws. Each inner connecting tube 675 includes at least four inner connecting tubes 675 arranged in a circular array. The inner connecting tubes 675 are integrally formed with the wall sleeve body 671 to ensure sufficient sealing. The connecting holes penetrate the inner and outer circumferential surfaces of the wall sleeve body 671, providing an effective connection node for the screws. The screw holes on the fixing ring 676 are countersunk holes, allowing the screws to connect the fixing ring 676 and the wall sleeve body 671 in a concealed manner. The fixing ring 676 can effectively limit the maximum creep deformation allowance of the curved annular protrusion 672 by segmenting, allowing the peristaltic fluid 673 and the peristaltic ball 674 to obtain multi-directional extrusion and deformation while maintaining reasonable constraints, which is beneficial to promoting the shearing of the material by the grinding media.

[0027] like Figure 12As shown, the present invention provides three levers 65, which are staggered vertically on the main shaft 62. By staggering the levers 65, the spiral path of the grinding belt 68 can be avoided, and the levers can be used in conjunction with the grinding media with a certain filling depth to provide corresponding stirring power to the grinding media at different depths, thereby improving the fullness and flexibility of the grinding media's movement and thus improving the grinding efficiency of the dispersion system.

[0028] To improve the utilization rate of the grinding belt 68, the inner wall of the grinding belt 68 provided by the present invention can be designed with a frosted surface to improve the wear resistance and grinding performance of the grinding belt 68. Based on this, the cross-section of the grinding belt 68 provided by the present invention is π-shaped and includes a first curved surface belt 681, a second curved surface belt 682, and a third curved surface belt 683. The second curved surface belt 682 is located at the ends of the first curved surface belt 681 and the third curved surface belt 683, and its two ends are engaged with the root of the spiral groove. The three inner walls of the grinding belt 68 are arc-shaped towards the center of the spiral groove and each is provided with a plurality of zirconium beads 684. The zirconium beads 684 on the same inner wall are evenly spaced along the spiral extension direction of the grinding belt 68. The spiral groove has a dovetail groove structure in cross-section, and the root of the dovetail groove is provided with a slot wider than the dovetail groove. This slot engages with both ends of the second curved surface band 682, preventing the grinding band 68 from automatically detaching from the triple spiral groove 621 due to deformation and being stirred into the dispersion system. The starting surfaces of the first curved surface band 681, the second curved surface band 682, and the third curved surface band 683 are provided with nesting openings for embedding zirconium beads 684. After the zirconium beads 684 are nested in the nesting openings, one side of the zirconium bead 684 contacts the groove wall of the spiral groove, providing a floating allowance for the grinding band 68. The other side of the zirconium bead 684 is located within the groove path inside the grinding band 68, and is positioned... The zirconium beads 684 on other curved surfaces can generate corresponding extrusion and friction, and the extrusion and friction of the zirconium beads 684 can provide a certain self-rotation driving force, improving the uniformity of the zirconium beads 684 participating in friction and extrusion work; during the continuous rotation of the main shaft 62, the first curved surface belt 681, the second curved surface belt 682 and the third curved surface belt 683 can generate effective floating due to the influence of fluid pressure. This floating can increase the resistance of the first curved surface belt 681 and the second curved surface belt 682 to detach from the spiral groove, and the frequent extrusion and friction generated by the floating can provide sufficient support for the zirconium beads 684 to shear the material, which is conducive to improving the grinding fineness of the material.

[0029] To improve the compatibility between the residual liquid recovery device 8 and the basket grinding mechanism 6, and considering the necessity of the basket grinding mechanism 6 entering and exiting the container, the residual liquid recovery device 8 provided by the present invention is coordinated with the lifting position of the basket grinding mechanism 6. Specifically, the residual liquid recovery device 8 provided by the present invention includes two symmetrically distributed swing arms 81. The power input ends of the two swing arms 81 are provided with opening and closing drive mechanisms 82. The ends of the swing arms 81 far from the opening and closing drive mechanisms 82 are provided with half-cylinders 83, and the bottom of one half-cylinder 83 is provided with a water receiving tank 84. A recovery pipe 85 is provided on one side of the water receiving tank 84. The opening and closing drive mechanism 82 includes an opening and closing drive motor 5. The power output end of the opening and closing drive motor 5 is equipped with an active swing gear shaft, and the transmission side of the active swing gear shaft is equipped with a driven swing gear shaft meshing with it. The active and driven swing gear shafts are respectively connected to different swing arms 81. The opening and closing drive motor 5 outputs power to the active swing gear shaft, and the active and driven swing gear shafts output opposite clockwise swinging motions to the two swing arms 81. The swing arm 81 includes a horizontal section located at the top of the transmission box 4 and a section extending from the top of the transmission box 4. The bent section below the transmission box 4 avoids the necessary position of the transmission box 4 to achieve an effective connection with the half-cylinder 83, especially ensuring that the residual liquid recovery device 8 fully closes the bottom of the basket grinding mechanism 6 when closed, thereby reasonably recovering the residual liquid. The water tank 84 and one of the half-cylinders 83 are integral structures, and sealing strips are provided on the opposite surfaces of the two half-cylinders 83. When they close from opposite directions, they can effectively cover the dripping range of the residual liquid from the basket grinding mechanism 6. The residual liquid is then recovered from the water tank 84 to the container in the workshop through the recovery pipe 85. The residual liquid recovery device 8, through reasonable opening and closing actions, does not affect the working function of the basket grinding mechanism 6 and effectively completes the recovery of residual liquid. The design is reasonable and highly practical.

[0030] To improve the environmental friendliness of the workshop, the purification device 7 provided by the present invention includes a purification box 71. The purification box 71 includes two purification sections 711 distributed on both sides of the transmission box 4 and a flow guide section 712 communicating with the two purification sections 711. The purification section 711 is filled with a purification unit 72. The bottom surface of the flow guide section 712 is provided with an inclined flow guide surface and the front of the flow guide surface faces the basket grinding mechanism 6. The flow guide surface is provided with a mounting groove 713 recessed towards the inside of the flow guide section 712. The inner wall of the mounting groove 713 is provided with a plurality of ventilation holes 714. The end of the mounting groove 713 is provided with an exhaust fan 73. The cross-section of the inlet section 712 is roughly triangular. The exhaust fan 73 draws gas from the vicinity of the basket grinding mechanism 6 into the inner side of the mounting groove 713 via suction. After entering the inlet section 712 through the ventilation hole 714, the gas is guided along the triangular face of the inlet section 712 to the purification section 711. The purification unit 72 in the purification section 711 purifies the gas passing through it through physical and chemical treatments, thereby improving the gas quality in the workshop. The purification unit 72 can be selected according to the specific gas parameters that the material can produce, such as activated carbon packing, catalytic packing, and metal filter elements, to effectively purify the gas.

[0031] To improve the production efficiency of the dispersion system, the basket 641 provided by the present invention is provided with a positioning ring 69 at the top. The positioning ring 69 is provided with a flow guide 610. The flow guide 610 includes an outer flow guide surface 6101 and a double-cone inner flow guide surface 6102. The outer flow guide surface 6101 is provided with a spout 6103 that mates with the long rod bolt 66. The inner side of the inner flow guide surface 6102 is provided with a positioning ring groove 6104 that mates with the positioning ring 69. The top cross-section of the positioning ring 69 is mushroom-shaped, and the cross-sectional dimension of the positioning ring groove 6104 is slightly larger than that of the positioning ring 69 to ensure that the two form a quick snap-fit ​​relationship. At the same time, the spout 6103 and the long rod bolt 66 are in a quick snap-fit ​​relationship. In order to ensure the assembly performance of the guide component 610, the guide component 610 adopts a two-half butt-fit design. One half can be snapped onto the long rod bolt 66 from the inside. After the guide component 610 is butt-fitted, it can form a continuous outer guide surface 6101 and inner guide surface 6102. In particular, the double-cone design of the inner guide surface 6102 can promote the rapid entrainment of fluid into the inner wall of the basket 641, and generate a trumpet-mouth amplification effect at the lower half of the cone surface, improving the fullness of material contact with the grinding media, thereby improving the grinding efficiency of the basket grinding mechanism 6 on the material and the production efficiency of the entire dispersion system.

[0032] The application of a mixing device in a production line for the compounding of difenoconazole and pyraclostrobin involves using the mixing device provided by this invention to mix difenoconazole and pyraclostrobin. The compounding system of difenoconazole and pyraclostrobin is a dispersion system, mainly used as a pesticide suspension. In this production process, the mixing device provided by this invention achieves efficient grinding and dispersion while ensuring the environmental friendliness and safety of the production process. To improve the safety of the peristaltic wall sleeve, the peristaltic fluid and peristaltic balls inside the peristaltic wall sleeve can be made of the same materials as the material and the grinding media. For example, the peristaltic fluid can be a suspension containing difenoconazole and pyraclostrobin, and the peristaltic balls can be zirconium beads. This ensures that even if the peristaltic wall sleeve is damaged or leaks, the physicochemical properties of the material will not be affected. To improve the processing performance of the purification unit, in the process of producing the compound system of difenoconazole and pyraclostrobin, the present invention uses multiple purification units to form a multi-module, such as modified activated carbon loaded with metal oxides, and a UV photolysis module to oxidize and decompose residual odor molecules (such as aromatics and esters) that have not been completely removed into CO2 and water.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
