Abstract
Description
Technical Field
[0001] This utility model relates to the field of special equipment for water-based coatings, specifically a mixing tank for the production of water-based coatings with anti-sedimentation function. Background Technology
[0002] Water-based coatings are coatings that use water as a solvent or dispersion medium. They mainly include water-soluble coatings, water-dilutable coatings, and water-dispersible coatings. Water-based coatings are often stored in storage tanks for storage and retrieval. However, water-based coatings tend to settle due to their own gravity, which affects the uniformity and quality of the coating when it is used. Moreover, the coatings are affected by the weather. When the weather is cold, the viscosity of water-based coatings increases or they freeze, which affects the normal use of the coatings.
[0003] Patent CN209939498U discloses a storage tank for preventing sedimentation of water-based coatings. The tank includes a body with a discharge port at its lower end. A first valve is installed at the discharge port. A vertically oriented rotating shaft is located inside the tank. The upper end of the shaft extends through the top of the tank and is connected to a motor. The lower end of the shaft is located in the discharge port. Several outwardly inclined stirring layers are evenly distributed along the height of the shaft, with adjacent stirring layers tilting in opposite directions. This invention uses these stirring layers to stir coatings at different heights, and the opposite tilt directions of adjacent stirring layers improve the stirring speed and achieve uniform mixing. The stirring layer and spiral blades prevent sedimentation of the coating. The coating is stirred by the long strip and elliptical stirring plates, which improves the uniformity of the coating and the quality of use. In cold weather, the first water pipe heats the coating in the tank to ensure normal stirring and mixing, thus ensuring normal use of the coating. Although heating can prevent sedimentation, excessively high ambient temperatures may cause the temperature of the water-based coating to rise. This temperature rise may accelerate the hydrolysis of the resin in the water-based coating or cause the decomposition agent to become ineffective, thus still potentially leading to sedimentation. Utility Model Content
[0004] To overcome the shortcomings of existing technologies and prevent precipitation caused by excessively high temperatures, this invention proposes a mixing tank for the production of water-based coatings with anti-precipitation function.

[0006] The driven component includes a receiving plate and a receiving rod. The receiving plate is fixedly connected to the bottom end of the mixing cylinder. A stirring assembly is detachably connected to the side wall of the receiving plate. The stirring assembly is inserted into the inner cavity of the mixing cylinder.
[0007] A receiving rod is fixedly connected to the outer wall of the drive assembly. A guide plate is fixedly connected to the end of the receiving rod away from the drive assembly.

[0008] Preferably, the stirring assembly includes a drive motor, which is detachably connected to the side wall of the receiving plate. An eccentric shaft is fixedly connected to the output end of the drive motor. A sleeve is rotatably connected to the end of the eccentric shaft away from the drive motor. A lifting rod is fixedly connected to the inner side wall of the sleeve. A mounting plate is fixedly connected to the top of the lifting rod. A rotating shaft is rotatably connected to the upper surface of the mounting plate. The rotating shaft passes through the inner cavity of the mixing cylinder and has a limit groove. Multiple arc-shaped plates are fixedly connected to the outer side wall of the rotating shaft.
[0009] Preferably, the driving assembly includes a second driving motor, which is detachably connected to the top wall of the mixing drum. The output end of the second driving motor is fixedly connected to a plug rod, which is inserted into the limiting groove.
[0010] Preferably, the mixing cylinder includes an upper cylinder and a lower cylinder, the upper cylinder is detachably connected to the top of the lower cylinder, an inlet cylinder is inserted through the top wall of the upper cylinder, and a sealing valve is detachably connected to the top of the inlet cylinder.

Through the dual mechanism of prevention and treatment, the uniformity and storage stability of the coating are significantly improved, and the possibility of sedimentation in water-based coatings is reduced.

[0023] 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 scope of protection of the present utility model.
[0024] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0025] This application discloses a mixing tank for producing water-based coatings with anti-sedimentation function. (See also...) Figure 1 , Figure 2 and Figure 3 A mixing tank for producing water-based coatings with anti-settling function includes a mixing cylinder 1. The mixing cylinder 1 includes an upper cylinder 11 and a lower cylinder 12. The upper cylinder 11 is detachably connected to the top of the lower cylinder 12. A feed cylinder 13 is inserted through the top wall of the upper cylinder 11. A sealing valve 14 is detachably connected to the top of the feed cylinder 13. A drive assembly 2 is detachably connected to the top of the upper cylinder 11. A driven component 3 is detachably connected to the bottom of the lower cylinder 12. The driven component 3 is inserted into the inner cavity of the mixing cylinder 1, and the drive assembly 2 is inserted into the driven component 3.
[0026] It should be noted that an outer shell 15 is fixedly connected to the side wall of the lower cylinder 12. An insulation cavity 16 is formed between the outer shell 15 and the lower cylinder 12. A water inlet 17 is inserted near the bottom of the side wall of the outer shell 15, and a water outlet 18 is inserted near the top of the side wall of the outer shell 15. Both the water inlet 17 and the water outlet 18 extend into the insulation cavity 16. Temperature fluctuations may cause precipitation in the water-based coating. For example, when the water-based coating in the mixing drum 1 is at a high temperature, the resin hydrolysis in the water-based coating may accelerate or the decomposing agent may become ineffective, potentially leading to precipitation. When the coating is at a low temperature, it may cause the emulsion to break down or the thickener to deteriorate, resulting in precipitation. Therefore, under the action of the insulation cavity 16, a solution with a constant temperature is injected into the insulation cavity 16 through the water inlet 17 and discharged through the water outlet 18 to maintain the fluidity of the solution in the insulation cavity 16, so that the insulation cavity 16 can achieve the effect of heat preservation of the inner cavity of the lower cylinder 12. The outer wall of the lower cylinder 12 is fixedly connected to the mounting bracket 4, and multiple support legs 5 are fixedly connected to the bottom end of the mounting bracket 4. The receiving plate 31 is fixedly connected to the side wall of the support leg 5.
[0027] Reference Figure 2 , Figure 3 and Figure 4The driven component 3 includes a receiving plate 31 and a receiving rod 32. The receiving plate 31 is fixedly connected to the bottom end of the mixing cylinder 1. A stirring assembly 33 is detachably connected to the side wall of the receiving plate 31. The stirring assembly 33 includes a drive motor 331. The drive motor 331 is detachably connected to the side wall of the receiving plate 31. An eccentric shaft 332 is fixedly connected to the output end of the drive motor 331. A sleeve 333 is rotatably connected to the end of the eccentric shaft 332 away from the drive motor 331. A lifting rod 334 is fixedly connected to the inner side wall of the sleeve 333. A mounting plate 335 is fixedly connected to the top end of the lifting rod 334. A rotating shaft 336 is rotatably connected to the upper surface of the mounting plate 335. The rotating shaft 336 is inserted into the inner cavity of the mixing cylinder 1, and a limit groove 337 is opened in the rotating shaft 336. Multiple arc-shaped plates 338 are fixedly connected to the outer side wall of the rotating shaft 336.
[0028] Reference Figure 2 and Figure 4 A receiving rod 32 is fixedly connected to the outer wall of the drive assembly 2. A guide plate 34 is fixedly connected to the end of the receiving rod 32 away from the drive assembly 2. An installation groove 35 is opened in the guide plate 34. A grinding roller 36 is rotatably connected in the installation groove 35. The side wall of the grinding roller 36 is in contact with the side wall of the inner cavity of the mixing cylinder 1. A drive wheel 37 is fixedly connected to the bottom end of the grinding roller 36. The bottom wall of the drive wheel 37 is in contact with the bottom wall of the inner cavity of the installation groove 35.
[0029] It should be noted that the eccentric shaft 332 is driven to rotate by the drive motor 331. The eccentric shaft 332 drives the lifting rod 334 to rise and fall through the adjustment. The lifting rod 334 drives the rotating shaft 336 to rise and fall through the mounting plate 335. Multiple stirring plates 339 are fixedly connected to the side wall of the rotating shaft 336 near the bottom. The multiple stirring plates 339 are arranged in a circular array around the central axis of the rotating shaft 336. When the rotating shaft 336 rises and falls, the multiple stirring plates 339 stir the water-based coating in the inner cavity of the mixing cylinder 1, causing the water-based coating to tumble in the inner cavity of the mixing cylinder 1, thereby avoiding the precipitation of the water-based coating. Even if some precipitation still occurs in the water-based coating during this process, the precipitation will be lifted upward under the action of the stirring plates 339, and then guided by the arc plate 338, so that the precipitation flows towards the side wall of the inner cavity of the mixing cylinder 1. When the precipitation approaches the side wall of the inner cavity of the mixing cylinder 1, the guide plate 34 will guide the precipitation and make the precipitation flow towards the grinding roller 36.
[0030] Reference Figure 1 and Figure 2 The drive assembly 2 includes a second drive motor 21, which is detachably connected to the top wall of the mixing drum 1. The output end of the second drive motor 21 is fixedly connected to a plug rod 22, which is inserted into the limiting groove 337. The receiving rod 32 is fixedly connected to the side wall of the plug rod 22.
[0031] It should be noted that the drive motor 21 drives the plug rod 22 to rotate, and the plug rod 22 drives the receiving rod 32 to rotate. When the receiving rod 32 rotates, the drive wheel 37 and the water-based coating move relative to each other. Under the action of the water-based coating, the drive wheel 37 rotates, which in turn causes the grinding roller 36 to rotate. The rotation of the grinding roller 36 grinds the sediment accumulated near the grinding roller 36, thereby eliminating the sediment.
[0032] Working Principle: During the production of water-based coatings, the drive motor 331 is first started. The drive motor 331 drives the eccentric shaft 332 to rotate. The eccentric shaft 332, through adjustment, drives the lifting rod 334 to rise and fall. The lifting rod 334, through the mounting plate 335, drives the rotating shaft 336 to rise and fall. When the rotating shaft 336 rises and falls, multiple stirring plates 339 stir the water-based coating inside the mixing drum 1, causing the raw materials of the water-based coating to tumble within the mixing drum 1, thereby preventing sedimentation. Even if some sedimentation still occurs during this process, the sediment will rise under the action of the stirring plates 339 and then... The arc-shaped plate 338 guides the sediment to flow towards the inner wall of the mixing cylinder 1. When the sediment approaches the inner wall of the mixing cylinder 1, the guide plate 34 guides the sediment and causes it to flow towards the grinding roller 36. The drive motor 21 drives the insertion rod 22 to rotate, which in turn drives the receiving rod 32 to rotate. When the receiving rod 32 rotates, the drive wheel 37 moves relative to the water-based coating. Under the action of the water-based coating, the drive wheel 37 rotates, which in turn causes the grinding roller 36 to rotate. The rotation of the grinding roller 36 then grinds the sediment accumulated near the grinding roller 36, thereby eliminating the sediment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
