Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, specifically to an anti-sedimentation mixing tank for the production of metribuzin aqueous solution. Background Technology

[0002] As a widely used herbicide, metribuzin aqueous solution requires a mixing tank during its production to ensure uniform mixing of raw materials and solvents, thereby ensuring the dispersion of the active ingredients and directly affecting the product's efficacy stability and effectiveness. The mixing tanks commonly used in the industry for metribuzin aqueous solution production are traditional single-stirring structures, mainly consisting of a tank body, motor, stirring paddle, and support components. Their working principle is that the motor drives a single stirring paddle to rotate within the tank, using the paddle's agitation to achieve solution mixing.

[0003] In actual production applications, some components in the raw materials for metribuzin aqueous solution tend to form large-sized particulate flocs, and the density of these particulate flocs is slightly higher than that of the solvent. Traditional stirring paddles have a weak disturbance effect on the solution at the bottom of the tank, causing the particulate flocs to easily deposit and accumulate at the bottom of the tank, forming a sediment layer. The presence of the sediment layer not only prevents the raw materials from fully participating in the mixing reaction, resulting in insufficient product mixing uniformity and affecting the consistency of efficacy, but also leads some manufacturers to try to solve the sedimentation problem by increasing the stirring power or extending the stirring time. However, this increases energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide an anti-settling mixing tank for the production of metribuzin aqueous agent. It has the advantage of a dual mixing structure that enables all-round mixing and sedimentation conveying, and solves the problems of poor bottom mixing and complex structure of multi-motor equipment in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A sedimentation-preventing mixing tank for the production of metribuzin aqueous agent includes a support assembly, which includes a protective cover. A mixing assembly is installed on the inner wall of the center of the protective cover. The mixing assembly includes a hollow shaft rotatably mounted on the inner wall of the center of the protective cover. A rotating frame is fixed to the outer wall of the lower end of the hollow shaft. Symmetrically distributed movable sleeves are installed on the outer wall of the rotating frame. A fixed sleeve is fixed to the lower end of the movable sleeve. A mixing paddle is installed inside the fixed sleeve. The mixing assembly also includes a rotating shaft rotatably mounted on the inner wall of the hollow shaft. The lower end of the rotating shaft extends out of the lower end opening of the hollow shaft and is fixed to an auger. A drive assembly is installed on the upper end of the protective cover. The drive assembly includes a motor frame fixed to the upper end of the protective cover. A servo motor is fixed to the inner wall of the upper end of the motor frame. The output end of the servo motor is connected to drive the hollow shaft and the rotating shaft.

[0006] Preferably, the supporting assembly also includes a mixing tank fixedly installed at the lower end of the protective cover, and the stirring components are all located inside the mixing tank.

[0007] It is worth noting that the mixing tank provides a closed mixing space for the mixing components, preventing the leakage of raw materials for metribuzin aqueous solution production. At the same time, its inner wall can guide the material to form a circulation during mixing. Combined with the mixing paddle on the rotating frame and the bottom auger, it can achieve all-round mixing from the tank wall to the bottom of the tank, ensuring uniform contact of the material.

[0008] Preferably, the support component also includes a protective cover fixed to the upper end of the protective cover, and the drive components are all located inside the protective cover.

[0009] It is worth noting that the protective cover can isolate the drive components from the outside world, preventing dust and moisture in the production environment from entering the drive components and affecting the transmission accuracy. At the same time, it can prevent operators from accidentally touching the high-speed rotating gear structure, ensuring the safety of equipment operation and drive stability, and providing a protective basis for the coordinated operation of the dual stirring structure.

[0010] Preferably, the outer wall of the rotating frame is provided with equidistant limiting holes, and the outer wall of the movable sleeve is provided with a screw hole. A bolt is installed in the screw hole, and the end of the bolt is inserted into the limiting hole.

[0011] It is worth noting that by inserting bolts through the screw hole into the limiting hole at different positions, the installation position of the movable sleeve on the rotating frame can be flexibly adjusted, thereby changing the stirring radius of the stirring paddle, adapting to materials at different liquid levels in the mixing tank, expanding the stirring coverage area, and ensuring that the movable sleeve does not loosen during stirring, while also facilitating disassembly and adjustment, thus enhancing the adaptability of the device to different production conditions.

[0012] Preferably, a screw hole 2 is provided through the outer wall of the fixed sleeve, and a limit hole 2 is provided through the outer wall of the upper end shaft of the agitator. A bolt is installed in the screw hole 2 with its internal thread, and the end of the bolt is inserted into the limit hole 2.

[0013] It is worth noting that by inserting the bolt through the second screw hole into the second limiting hole, the mixing paddle can be firmly fixed in the fixing sleeve. This structure allows for quick removal of the bolts to replace mixing paddles of different specifications (such as different blade angles and lengths) to adapt to the mixing characteristics of different raw materials of metribuzin aqueous solution, ensuring mixing efficiency and convenient maintenance.

[0014] Preferably, a gear one is fixedly connected to the upper outer wall of the hollow shaft, the output end of the servo motor is fixedly connected to the rotating shaft, and a gear two is also installed on the outer wall of the output end of the servo motor.

[0015] It is worth noting that by using a servo motor as a single power source, it can directly drive the rotating shaft and transmit the power to gear one through gear two at the output end, thus realizing a "single motor driven dual stirring structure". This greatly simplifies the equipment structure. At the same time, the servo motor can precisely control the speed to ensure that the speed of the hollow shaft and the rotating shaft are matched.

[0016] Preferably, the drive assembly further includes a fixed frame fixed to the upper end of the protective cover, and a gear shaft is rotatably mounted on the inner walls of the upper and lower ends of the fixed frame. The upper gear of the gear shaft meshes with gear two, and the lower gear of the gear shaft meshes with gear one through an idler gear for transmission.

[0017] It is worth noting that: by providing stable support for the gear shaft through the fixed frame, the gear shaft can achieve reverse rotation of the hollow shaft and the rotating shaft through the meshing of the upper gear and the gear two, and the meshing of the lower gear and the gear one through the idler wheel. This allows the stirring paddle on the rotating frame to form convection stirring with the bottom auger, which enhances the tumbling intensity of the material and prevents it from settling and accumulating at the bottom.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides an integrated mounting base for the mixing and driving components through a protective cover. The hollow shaft at its center and the internal rotating shaft form a nested double mixing core. When the hollow shaft rotates, it drives the lower rotating frame and the mixing paddles on the movable and fixed sleeves to radially mix the materials inside the mixing tank. The rotating shaft rotates independently and drives the lower auger to transport the sediment at the bottom of the tank upwards. The two work together to form a three-dimensional convection of "radial mixing + axial conveying". At the same time, the adjustable structure of the movable and fixed sleeves allows the mixing paddles to adapt to different liquid levels and material characteristics, further expanding the mixing coverage. The servo motor of the driving component drives the hollow shaft and the rotating shaft through a single power source, eliminating the need for multiple motors to work together, simplifying the structure while ensuring the matching of the two in operation.

Detailed Implementation

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To address the problems of poor bottom mixing in traditional mixing tanks and the complex structure and difficulty in coordinating multi-motor equipment in existing technologies, the following technical solution is proposed. Please refer to [link / reference needed]. Figures 1-5 ; A sedimentation-preventing mixing tank for the production of metribuzin aqueous agent includes a support assembly. The support assembly includes a protective cover 102. A mixing assembly is installed on the inner wall of the center of the protective cover 102. The mixing assembly includes a hollow shaft 201 rotatably mounted on the inner wall of the center of the protective cover 102. A rotating frame 203 is fixedly connected to the outer wall of the lower end of the hollow shaft 201. Symmetrically distributed movable sleeves 207 are installed on the outer wall of the rotating frame 203. A fixed sleeve 208 is fixedly connected to the lower end of the movable sleeve 207. An agitator is installed inside the fixed sleeve 208. The paddle 210 and the stirring assembly also include a rotating shaft 204 rotatably mounted on the inner wall of the hollow shaft 201. The lower end of the rotating shaft 204 extends out of the lower end opening of the hollow shaft 201 and is fixedly connected to an auger 205. A drive assembly is installed on the upper end of the protective cover 102. The drive assembly includes a motor frame 301 fixedly connected to the upper end of the protective cover 102. A servo motor 302 is fixedly connected to the inner wall of the upper end of the motor frame 301. The output end of the servo motor 302 is connected to drive the hollow shaft 201 and the rotating shaft 204.

[0023] The protective cover 102 provides an integrated mounting base for the mixing and driving components. The hollow shaft 201 at its center and the internal rotating shaft 204 form a nested double mixing core. When the hollow shaft 201 rotates, it drives the lower rotating frame 203 and the stirring paddle 210 on the movable sleeve 207 and the fixed sleeve 208 to perform radial mixing of the materials inside the mixing tank 101. The rotating shaft 204 rotates independently and drives the lower auger 205 to transport the sediment at the bottom of the tank upward. The two work together to form a three-dimensional convection of "radial mixing + axial conveying". At the same time, the adjustable structure of the movable sleeve 207 and the fixed sleeve 208 allows the stirring paddle 210 to adapt to different liquid levels and material characteristics, further expanding the mixing coverage. The servo motor 302 of the driving component drives the hollow shaft 201 and the rotating shaft 204 through a single power source, eliminating the need for multiple motors to work together, simplifying the structure while ensuring that the two operate in a matched manner.

[0024] Please see Figure 2The supporting components also include a mixing tank 101 fixedly installed at the lower end of the protective cover 102, and the stirring components are all located inside the mixing tank 101. The mixing tank 101 can provide a closed stirring space for the stirring components to prevent the raw materials for the production of metribuzin liquid from leaking out. At the same time, its inner wall can guide the material to form a circulation during stirring. In conjunction with the stirring paddle 210 on the rotating frame 203 and the bottom auger 205, it can achieve all-round mixing from the tank wall to the bottom of the tank, ensuring uniform contact of the material.

[0025] The supporting components also include a protective cover 103 fixed to the upper end of the protective cover 102, and the drive components are all located inside the protective cover 103. The protective cover 103 can isolate the drive components from the outside world, prevent dust and moisture in the production environment from entering the drive components and affecting the transmission accuracy, and at the same time prevent operators from accidentally touching the high-speed rotating gear structure, ensuring the safety of equipment operation and drive stability, and providing a protective foundation for the coordinated work of the dual stirring structure.

[0026] Please see Figure 3 The outer wall of the rotating frame 203 is provided with equidistantly distributed limiting holes 206, and the outer wall of the movable sleeve 207 is provided with a threaded hole 209. A bolt is installed in the threaded hole 209, and the end of the bolt is inserted into the limiting hole 206. By inserting the bolt through the threaded hole 209 into the limiting hole 206 at different positions, the installation position of the movable sleeve 207 on the rotating frame 203 can be flexibly adjusted, thereby changing the stirring radius of the stirring paddle 210, adapting to materials with different liquid levels in the mixing tank 101, expanding the stirring coverage area. The bolt fixing method ensures that the movable sleeve 207 does not loosen during stirring, and also facilitates disassembly and adjustment, enhancing the adaptability of the device to different production conditions.

[0027] The outer wall of the fixed sleeve 208 is provided with a threaded hole 212, and the outer wall of the upper shaft of the stirring paddle 210 is provided with a limiting hole 211. A bolt is installed in the threaded hole 212, and the end of the bolt is inserted into the limiting hole 211. By inserting the bolt through the threaded hole 212 into the limiting hole 211, the stirring paddle 210 can be firmly fixed in the fixed sleeve 208. This structure allows for quick removal of the bolt to replace the stirring paddle 210 with different specifications (such as different blade angles and lengths) to adapt to the mixing characteristics of different raw materials of metribuzin aqueous solution, ensuring mixing efficiency and convenient maintenance.

[0028] Please see Figure 4 and Figure 5Gear 202 is fixedly connected to the upper outer wall of the hollow shaft 201. The output end of the servo motor 302 is fixedly connected to the rotating shaft 204. Gear 303 is also installed on the outer wall of the output end of the servo motor 302. By using the servo motor 302 as a single power source, it can directly drive the rotating shaft 204 and transmit the power to gear 202 through gear 303 at the output end, realizing a "single motor driven dual stirring structure", which greatly simplifies the equipment structure. At the same time, the servo motor 302 can precisely control the speed to ensure that the speed of the hollow shaft 201 and the rotating shaft 204 are matched.

[0029] The drive assembly also includes a fixed frame 304 fixed to the upper end of the protective cover 102. Gear shafts 305 are rotatably mounted on the inner walls of the upper and lower ends of the fixed frame 304. The upper gear of the gear shaft 305 meshes with gear two 303, and the lower gear of the gear shaft 305 meshes with gear one 202 through an idler wheel. The fixed frame 304 provides stable support for the gear shaft 305. The gear shaft 305 can achieve reverse rotation of the hollow shaft 201 and the rotating shaft 204 through the upper gear meshing with gear two 303 and the lower gear meshing with gear one 202 through an idler wheel. This allows the stirring paddle 210 on the rotating frame 203 and the bottom auger 205 to form convective stirring, enhance the material turning intensity, and prevent the material from settling and accumulating at the bottom.

[0030] Working principle: After the device is started, the servo motor 302 directly drives the rotating shaft 204 to rotate. At the same time, the gear 303 on its outer wall meshes and transmits the power to the upper gear of the gear shaft 305 in the fixed frame 304. The lower gear of the gear shaft 305 meshes with the gear 202 on the upper end of the hollow shaft 201 through the idler wheel, so that the hollow shaft 201 and the rotating shaft 204 rotate in opposite directions.

[0031] The rotating shaft 204 drives the auger 205 at the lower end to rotate at high speed, which axially transports the easily sedimented metribuzin aqueous raw material at the bottom of the mixing tank 101 upward, breaking the tendency of material stratification and sedimentation; at the same time, the hollow shaft 201 drives the rotating frame 203 to rotate synchronously, and the movable sleeve 207 on the rotating frame 203 is fixed by bolts through the screw hole 209 and the limiting hole 206, which drives the fixed sleeve 208 and the stirring paddle 210 to make radial circumferential motion, and to stir the material in the tank laterally.

[0032] Based on the material level and mixing characteristics, the stirring radius of the agitator 210 can be changed by adjusting the fixed position of the movable sleeve 207 at the limiting hole 206 on the rotating frame 203, or by removing the bolts at the screw hole 212 and the limiting hole 211 to replace the agitator 210 with a suitable one, ensuring that the stirring covers the entire liquid level and is adapted to the characteristics of the raw materials. During the stirring process, the mixing tank 101 guides the material to form a circulation, the protective cover 103 isolates dust and water vapor and protects the gear transmission structure, and the protective cover 102 ensures the integrated stability of each component. Finally, through the three-dimensional convection mode of "axial material lifting by the auger 205 + radial stirring by the agitator 210", the material is uniformly mixed from the bottom to the wall of the tank in all directions, avoiding sedimentation and accumulation. At the same time, the servo motor 302 precisely controls the speed to ensure the matching operation of the dual stirring structure, improving the stirring efficiency and the uniformity of material mixing.
