[0029] 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.

[0030] Reference Figure 1-4This utility model provides an embodiment of a multi-stage mixing tank, including a tank body 1, a cover plate 2 fixedly installed on the top of the tank body 1, a feed inlet 3 connected to the top of the cover plate 2, a discharge pipe 4 connected to the bottom of the tank body 1, a valve 5 connected to the surface of the discharge pipe 4, and a stirring assembly 6 for stirring the liquid inside the tank body 1. By setting up the tank body 1, cover plate 2, feed inlet 3, discharge pipe 4, valve 5 and stirring assembly 6, a complete liquid mixing process is formed. The design of the feed inlet 3 and discharge pipe 4 facilitates the input and output of materials, the valve 5 can accurately control the discharge rhythm, and the integration of the stirring assembly 6 provides the basic function for liquid stirring.

[0031] Reference Figure 1-4 The stirring assembly 6 includes a stirring rod 61. The top of the stirring rod 61 extends through to the top of the cover plate 2 and is movably installed with the cover plate 2. The bottom of the stirring rod 61 is movably installed with the bottom of the inner wall of the mixing tank body 1. Stirring blades 62 are fixedly installed on the surface of the stirring rod 61. Both ends of the stirring rod 61 are movably installed with the cover plate 2 and the bottom of the inner wall of the mixing tank body 1, respectively. This design ensures the stability and smoothness of the stirring rod 61 during rotation, reducing shaking or jamming. The stirring blades 62 are directly fixed to the surface of the stirring rod 61 and can rotate synchronously with the stirring rod 61, enabling direct and efficient stirring of the liquid in the tank, improving the uniformity and efficiency of liquid mixing. The liquid tank body 1 is equipped with three sets of scrapers 63. The outer side of the scrapers 63 contacts the inner wall of the liquid tank body 1, and the inner side of the scrapers 63 is fixedly installed on the surface of the stirring blades 62. By setting three sets of scrapers 63, the problem of liquid easily adhering to the tank wall and forming residue in the liquid tank body 1 is solved. When the scrapers 63 rotate synchronously with the stirring blades 62, they can scrape off the adhering material on the tank wall in real time, so that the residual material can re-participate in the stirring. This not only improves the material utilization rate, but also avoids the contamination of the residual material by the subsequent liquid preparation. At the same time, the close fit design between the scrapers 63 and the tank wall can also reduce the stirring dead corners, further improve the uniformity of liquid mixing, and facilitate subsequent cleaning and maintenance.

[0032] Reference Figure 1-4The stirring assembly 6 also includes a first synchronous pulley 64, which is fixedly mounted on the surface of the stirring rod 61. A rotating rod 65 is rotatably mounted on the top of the cover plate 2. An adjustable pulley 66 is fixedly mounted on the surface of the rotating rod 65. A synchronous belt 67 is provided on the top of the cover plate 2. The adjustable pulley 66 is driven by the synchronous belt 67 and the first synchronous pulley 64. A worm gear 68 is fixedly mounted on the surface of the rotating rod 65. A motor 69 is fixedly mounted on the top of the cover plate 2. A worm 610 is fixedly mounted on the output end of the motor 69. The worm 610 and the worm gear 68 mesh. The meshing transmission between the worm gear 68 and the worm 610 has self-locking and deceleration properties. The torque-increasing effect ensures stable stirring and prevents reverse rotation or slippage due to excessive load. The cooperation between the first synchronous pulley 64 and the adjustable pulley 66 with the synchronous belt 67 achieves efficient transmission of the stirring rod 61. The adjustable pulley 66 allows for flexible adjustment of the stirring speed, adapting to the stirring needs of different materials such as high-viscosity liquids and multiphase mixtures. A fixing block 7 is rotatably mounted at one end of the worm gear 610. The bottom of the fixing block 7 is fixedly mounted to the top of the cover plate 2. By setting the fixing block 7 at one end of the worm gear 610 and fixing it to the cover plate 2, the support stability of the worm gear 610 during rotation is enhanced. The addition of the fixing block 7 can... To effectively limit the radial displacement of the worm 610 and ensure the accuracy of the meshing between the worm gear 68 and the worm 610, a second synchronous pulley 611 is provided on the top of the cover plate 2. The surface of the second synchronous pulley 611 meshes with the interior of the synchronous belt 67. A connecting block 612 is rotatably mounted on the top of the second synchronous pulley 611. An electric push rod 613 is fixedly mounted on the top of the cover plate 2. The telescopic end of the electric push rod 613 is fixedly mounted on one side of the connecting block 612. The combined structure of the second synchronous pulley 611, the connecting block 612, and the electric push rod 613 realizes the automatic adjustment of the tension of the synchronous belt 67. The electric push rod 613 drives the connecting block 612 to move through telescopic movement. The movement adjusts the position of the second synchronous pulley 611, which can compensate for the loosening of the synchronous belt 67 due to long-term use, avoid transmission slippage, and ensure stable transmission of stirring power. A protective cover 8 is fixedly installed on the top of the cover plate 2. The electric push rod 613 and the motor 69 are both located inside the protective cover 8. The protective cover 8 effectively protects the core transmission components such as the electric push rod 613 and the motor 69, and can prevent external dust, moisture, impurities, etc. from entering the inside of the components, reducing the probability of component corrosion or failure. At the same time, the protective cover 8 can isolate the moving parts, prevent operators from accidentally touching them during equipment operation, and improve the operational safety of the equipment.

[0033] Working principle: First, the liquid to be stirred can be poured into the body 1 of the mixing tank through the feed port 3. When stirring is required, the motor 69 can be started. The output of the motor 69 drives the worm gear 610 to rotate. The rotation of the worm gear 610 drives the worm wheel 68 to rotate. The rotation of the worm wheel 68 drives the rotating rod 65 and the adjustable pulley 66 to rotate. The rotation of the adjustable pulley 66 drives the first synchronous pulley 64 to rotate through the synchronous belt 67. The rotation of the first synchronous pulley 64 drives the stirring rod 61 to rotate. The rotation of the stirring rod 61 drives the stirring blade 62 and the scraper 63 to rotate. The rotation of the stirring blade 62 can stir the liquid inside the mixing tank body 1, and the scraper 63 can clean the liquid inside the mixing tank body 1. The liquid inside the body 1 is stirred and scraped. When large-scale stirring of the inside of the liquid mixing tank body 1 is required, the electric push rod 613 can be activated. The telescopic end of the electric push rod 613 drives the connecting block 612 and the second synchronous pulley 611 to move. At this time, the synchronous belt 67 will gradually loosen. Then, the synchronous belt 67 can be adjusted to the maximum disc on the adjustable pulley 66. Then, the electric push rod 613 can drive the second synchronous pulley 611 to move, thereby tightening the synchronous belt 67, which improves the stirring efficiency of the stirring rod 61 and the stirring blade 62. After the liquid is stirred, the valve 5 can be opened. At this time, the liquid inside the liquid mixing tank body 1 will be discharged through the discharge pipe 4.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
