It features a tank structure, including a stirring system, heating or cooling devices, and a sealing system, and is equipped with precise metering and safety devices. Through mechanical improvements and optimizations to the stirring and discharging structures, efficiency and safety are enhanced, making it suitable for chemical, pharmaceutical, and other fields.

[0003] A corrosion-resistant chemical mixing tank includes a tank body, a stirring system, a heating / cooling device, a sealing system, a feeding and discharging structure, and metering and safety devices, which improve mixing and discharging efficiency through mechanical optimization.

[0004] Currently, traditional equipment often suffers from uneven material mixing due to the lack of agitation components. It cannot adjust the mixing mode to suit materials of varying viscosities, leading to unstable chemical product quality and impacting production efficiency and product yield. Furthermore, the absence of easily replaceable agitators makes maintenance and repair inconvenient. Traditional equipment also lacks cleaning and filtration components, making it difficult to thoroughly remove residual materials from the tank, which can contaminate subsequent batches and affect product purity. Simultaneously, the cleaning water cannot be recycled, resulting in water waste, increased production costs, and potential blockage of the discharge port by residual materials, disrupting normal production processes. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a corrosion-resistant chemical preparation tank, which aims to improve the situation in the prior art where traditional equipment does not mix materials evenly, cannot adjust the stirring mode accordingly, and has difficulty in completely removing residual materials inside the tank, which will contaminate subsequent batches of materials and affect product purity.

[0032] 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.

[0033] Reference Figures 2-4This utility model provides an embodiment of a corrosion-resistant chemical preparation tank, comprising a frame 1, a sliding groove 2 on the inner wall of the top of the frame 1, a discharge port 28 at the bottom of the frame 1, a fixing ring 3 inside the frame 1, a rotating ring 4 rotatably connected inside the fixing ring 3, a stirring assembly 5 inside the frame 1, a cleaning and filtering assembly 6 inside the frame 1, and a filter water tank 7 on one side of the frame 1. The stirring assembly 5 includes a motor 8, and its core function is to stir and mix the materials in the tank. The motor 8 drives a rotating rod 9, which in turn drives a stirring paddle 11 to rotate, so that the materials are evenly mixed to meet the requirements of chemical preparation. A threaded rod 12 is used to connect a fixing block 10 and a stirring paddle 11. 1. To facilitate the installation, disassembly, and replacement of the stirring paddle 11, the drive end of the motor 8 is rotatably connected to a rotating rod 9, and a fixing block 10 is fixedly connected inside the rotating rod 9. The stirring paddle 11 is threadedly connected to both sides of the fixing block 10, and a threaded rod 12 is threadedly connected to one side of the stirring paddle 11. A top cover 21 is fixedly connected to the top of the frame 1. The top cover 21 has a feed inlet 22, a cleaning water pipe inlet 23, and a cooling system inlet 24. Bolts 25 are provided on the outer wall of the top cover 21. A bolt ring 26 is fixedly connected to the top outer wall of the frame 1. The top cover 21 is threadedly connected to the top of the frame 1. A slider 27 is fixedly connected to the outer wall of the fixing ring 3. The slider 27 is slidably connected inside the sliding groove 2.

[0034] Reference Figure 1 , Figure 4 and Figure 5 The cleaning and filtering assembly 6 includes a fixed ring 13. The cleaning and filtering assembly 6 drives the scraper rod 15, scraper 16, and inclined rod 17 to rotate via the rotating ring 4, which can scrape off residual materials on the inner wall and bottom of the tank, thus cleaning the tank and assisting in material discharge. The filter block 18 in the filter water tank 7 can filter the cleaning water, etc., to achieve water resource recovery or preliminary material separation. The fixed ring 13 is fixedly connected to the outer wall of the rotating rod 9. The fixed rod 14 is fixedly connected to the outer wall of the fixed ring 13. One side of the fixed rod 14 is fixedly connected to the outer wall of the rotating ring 4. The scraper rod 15 is fixedly connected to the bottom of the rotating ring 4. The scraper 16 is fixedly connected to the bottom of the scraper rod 15. The inclined rod 17 is fixedly connected to the bottom of the scraper 16. The rotating rod 9 is fixedly connected to one side of the inclined rod 17. The filter water tank 7 includes a filter block 18. A cleaning water pipe 19 is provided on the top of the filter block 18 and is slidably connected to the filter water tank 7. A return water pipe 20 is provided on the bottom of the filter block 18 and is slidably connected to the filter water tank 7.

[0035] Working Principle: First, the stirring assembly 5 is started by the motor 8, which drives the rotating rod 9 to rotate at high speed. The fixed block 10, fixed on the rotating rod 9, rotates synchronously. Since the fixed block 10 is threadedly connected to the stirring paddle 11 on both sides through threaded rods 12, the stirring paddle 11 rotates together with the rotating rod 9, generating radial and axial forces on the material in the tank. The radial force causes the material to move in a circular motion, forming a vortex; the axial force propels the material to circulate up and down. By adjusting the angle and number of stirring paddles 11 (such as using a multi-layer staggered layout), the adaptability to materials of different viscosities can be enhanced. For example, when processing high-viscosity materials, the blade angle is increased to improve shear force; when processing low-viscosity materials, the angle is decreased to improve circulation efficiency. The speed of the motor 8 can be adjusted according to the characteristics of the material to ensure that the material is fully and evenly mixed.

[0036] The cleaning filter assembly 6 delivers water from the filter tank 7 to the tank via the cleaning water pipe 19. When the rotating rod 9 rotates, the fixing ring 13, fixed to its outer wall, rotates synchronously, driving the rotating ring 4 to rotate within the fixing ring 3 via the fixing rod 14. The scraper rod 15, scraper bar 16, and inclined bar 17 at the bottom of the rotating ring 4 rotate accordingly. The scraper bar 16 adheres tightly to the inner wall and bottom of the tank, scraping off residual material and pushing it towards the discharge port 28. Simultaneously, the cleaning water forms a flow within the tank, assisting in rinsing the material. The used water flows back to the filter tank 7 via the return water pipe 20, and can be recycled after being filtered by the filter block 18. The filter block 18 intercepts impurities in the water, achieving solid-liquid separation and ensuring the cleanliness of the cleaning water, thus completing the cleaning of the tank and the recycling of water resources.

[0037] 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.
