Description

Technical Field

[0001] This utility model relates to the field of water-based coating production, and in particular to a water-based coating production anti-settling device. Background Technology

[0002] Water-based coatings are environmentally friendly coatings that use water as a solvent or dispersion medium and are composed of film-forming substances, pigments, fillers, and additives. They are characterized by low VOCs and non-flammability and are widely used in construction, industry, and other fields. However, because the pigments and fillers in water-based coatings are prone to settling due to gravity, they can lead to quality problems such as stratification, segregation, agglomeration, hardening, and performance degradation. They can also prolong stirring time, aggravate equipment wear, and increase waste disposal costs. Therefore, it is necessary to achieve dynamic dispersion of coatings, eliminate equipment dead zones, and adapt to different process requirements through mechanical stirring, fluid circulation, and structural optimization of anti-settling equipment. This reduces the sedimentation rate, improves product homogeneity and production efficiency, and is a key piece of equipment for the industrial production of water-based coatings.

[0003] Existing anti-sedimentation equipment for water-based coating production mainly relies on the coordinated operation of mechanical stirring, fluid dynamics, structural optimization, and intelligent control. In terms of mechanical stirring, a high-speed dispersing paddle generates strong shear force to break up agglomerates, while a low-speed scraping paddle removes sediment from the tank walls. Variable frequency speed control is used to meet dispersion requirements at different stages. In terms of fluid dynamics, a circulating pump system creates a top-down circulation flow, using turbulence to counteract particle gravity settling. Spraying and pipeline mixing elements further enhance dispersion. Structural optimization eliminates dead zones through designs such as double-cone bottoms and guide plates, and an anti-adhesion coating reduces wall adhesion. The intelligent control system uses sensors to monitor parameters such as particle size and viscosity in real time, automatically adjusting the stirring speed and circulation flow rate. These multiple mechanisms work together to ensure uniform dispersion of pigments and fillers during water-based coating production, preventing sedimentation.

[0004] In the practical application of anti-settling equipment in water-based coating production, although the equipment attempts to reduce material residue through methods such as impeller wall scraping design and optimized tank tilt angle, it is still difficult to completely solve the problem of coating retention on the inner wall and dead corners of the mixing tank. After long-term accumulation, these residual coatings will gradually solidify and form scale, forming a stubborn coating. This not only wastes raw materials but also causes multiple hidden dangers. The pigments and fillers in the residual coating harden due to long-term static placement, which increases the difficulty of dispersion in subsequent batch production, reducing production efficiency. The scale layer becomes a breeding ground for microorganisms, especially in the high-temperature environment of summer, which can cause the coating to deteriorate and affect product quality. Traditional manual cleaning methods require disassembling equipment parts, which is time-consuming and incomplete cleaning can easily lead to cross-contamination between batches. In addition, the solidification of residual coatings will also aggravate equipment wear. For example, the gap between the impeller and the tank wall will increase due to scale buildup, resulting in a decrease in the wall scraping effect, further forming a vicious cycle and ultimately weakening the overall effectiveness of the anti-settling equipment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water-based coating production anti-sedimentation device, which aims to improve the problem that some water-based coating remains on the inner wall of the mixing tank during the use of the equipment, resulting in residue inside the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water-based coating production anti-settling equipment, comprising a mixing tank, an inlet pipe fixedly connected to the top of the mixing tank, an outlet pipe fixedly connected to the bottom of the mixing tank, a drive assembly provided at the top of the mixing tank, a temperature control pipe fixedly connected inside the mixing tank, a rotating shaft rotatably connected inside the mixing tank, multiple stirring blades fixedly connected to the outer wall of the rotating shaft, and multiple scraping assemblies provided on the outer wall of the rotating shaft;

[0007] Each of the scraping components includes a first connecting strip, a soft scraper, and a second connecting strip. One end of each first connecting strip is fixedly connected to the top of the rotating shaft. Both ends of each soft scraper are fixedly connected between the first connecting strip and the second connecting strip. One end of each second connecting strip is fixedly connected to the bottom of the rotating shaft.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a protective box and a motor. The bottom of the protective box is fixedly connected to the top of the mixing tank, the outer wall of the motor is fixedly connected to the inside of the protective box, and the output end of the motor is connected to the top of the rotating shaft.

[0010] As a further description of the above technical solution:

[0011] A water inlet pipe is fixedly connected to the top of the temperature control tube, and a water outlet pipe is fixedly connected to the bottom of the temperature control tube.

[0012] As a further description of the above technical solution:

[0013] Both the inlet and outlet pipes are slidably connected to the outer walls with sliding sleeves, and both the inlet and outlet pipes are fixedly connected to the outer walls with retaining rings.

[0014] As a further description of the above technical solution:

[0015] Each of the sliding sleeves has a spring on its inner wall. One end of each spring is fixedly connected to the inside of the sliding sleeve, and the other end of each spring is fixedly connected to one side of the fixing ring.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the motor is first started to drive the rotating shaft to start rotating, so that the stirring blades start to stir the water-based coating inside. At the same time as stirring, the connecting strips one and two at both ends of the rotating shaft drive the soft scraper to rotate simultaneously. This achieves the effect of scraping off the water-based coating adhering to the inner wall and stirring it at the same time during the use of the equipment. This avoids the problem of water-based coating remaining on the inner wall of the mixing tank during the use of the equipment, thus improving the efficiency of the anti-sedimentation equipment for water-based coating production.

[0024] 2. In this utility model, first hold the sliding sleeve and push it inward, then hold the water supply pipe and insert its front end into the water inlet pipe. After that, release the sliding sleeve so that it moves outward under the action of the spring. At the same time, its inner wall pushes the ball into the deepest part of the sliding groove to fix the water supply pipe inside the water inlet pipe. This achieves the effect of easily connecting the water supply pipe and the water inlet pipe during the use of the equipment, avoiding the problem of needing complicated operations to connect the water supply pipe and the water inlet pipe during the use of the equipment, thereby improving the convenience of the anti-settling equipment for water-based coating production.

[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 1-3 The present invention provides an embodiment of an anti-settling device for producing water-based coatings, comprising a mixing tank 1, an inlet pipe 2 fixedly connected to the top of the mixing tank 1 for introducing water-based coatings into the mixing tank 1, an outlet pipe 3 fixedly connected to the bottom of the mixing tank 1 for discharging the water-based coatings out of the mixing tank 1, a drive assembly provided at the top of the mixing tank 1 for driving the stirring blades 8 to rotate, a temperature control pipe 6 fixedly connected inside the mixing tank 1 for controlling the temperature inside the mixing tank 1, a rotating shaft 7 rotatably connected inside the mixing tank 1 for connecting the stirring blades 8, multiple stirring blades 8 fixedly connected to the outer wall of the rotating shaft 7 for stirring the water-based coatings, and multiple scraping assemblies provided on the outer wall of the rotating shaft 7 for scraping off residual water-based coatings on the inner wall of the mixing tank 1.

[0034] Each scraping assembly includes a connecting strip 9, a soft scraper 10, and a connecting strip 11. One end of each connecting strip 9 is fixedly connected to the top of the rotating shaft 7 to fix the soft scraper 10. Both ends of each soft scraper 10 are fixedly connected between the connecting strip 9 and the connecting strip 11 to scrape off the water-based coating remaining on the inner wall of the mixing tank 1 while participating in the mixing to prevent it from settling. One end of each connecting strip 11 is fixedly connected to the bottom of the rotating shaft 7 to fix the soft scraper 10. The drive assembly includes a protective box 4 and a motor 5. The bottom of the protective box 4 is fixedly connected to the top of the mixing tank 1 to protect the motor 5. The outer wall of the motor 5 is fixedly connected to the inside of the protective box 4 to provide power for the rotation of the rotating shaft 7. The output end of the motor 5 is connected to the top of the rotating shaft 7.

[0035] Specifically, as the start button is pressed, the power of the motor 5 is precisely transmitted to the rotating shaft 7 through the transmission device. The rotating shaft 7 begins to rotate at a constant speed, driving the stirring blade 8 to cut into the surface of the water-based coating. The stirring blade 8 fully mixes the pigments and fillers settled at the bottom with the resin solution suspended on the upper layer. At the same time, the connecting strips 9 and 11 at both ends of the rotating shaft 7 also rotate synchronously. The soft scraper 10 fixed at its end adheres to the inner wall of the mixing tank 1 as it rotates. Each time the soft scraper 10 sweeps, it scrapes off the coating adhering to the tank wall. The coating that would have solidified and precipitated is returned to the flowing coating under the action of the soft scraper 10, ensuring that all the coating inside the tank remains in motion and preventing the water-based coating from settling.

[0036] Reference Figure 4 and Figure 5 A water inlet pipe 12 is fixedly connected to the top of the temperature control pipe 6 for introducing water at the required temperature into the temperature control pipe 6. A water outlet pipe 13 is fixedly connected to the bottom of the temperature control pipe 6 for draining the water that has achieved temperature control inside the temperature control pipe 6. Sliding sleeves 14 are slidably connected to the outer walls of both the water inlet pipe 12 and the water supply pipe 19, as well as the water outlet pipe 13 and the water delivery pipe 20. Fixing rings 15 are fixedly connected to the outer walls of both the water inlet pipe 12 and the water outlet pipe 13 to limit the movement range of the sliding sleeves 14. A spring 16 is provided on the inner wall of each sliding sleeve 14 to provide elastic force to the sliding sleeve 14. One end of each spring 16 is fixedly connected inside the sliding sleeve 14. The other end of each spring 16 is fixedly connected to one side of the fixed ring 15. Multiple sliding grooves 17 are provided inside the water inlet pipe 12 and the water outlet pipe 13 to accommodate the balls 18. Multiple balls 18 are slidably connected inside the water inlet pipe 12 and the water outlet pipe 13 to fix the water supply pipe 19 or the water delivery pipe 20. The water supply pipe 19 is slidably connected inside the water inlet pipe 12 to deliver water into the water inlet pipe 12. The water delivery pipe 20 is slidably connected inside the water outlet pipe 13 to discharge the water flowing out of the water outlet pipe 13. The balls 18 are arranged in a ring array inside the water inlet pipe 12 and the water outlet pipe 13. The outer wall of each ball 18 is slidably connected inside the sliding groove 17.

[0037] Specifically, the operator holds the sliding sleeve 14 with both hands and applies an inward pushing force, causing the sliding sleeve 14 to slide on the outer wall of the water inlet pipe 12. Then, the operator holds the water delivery pipe 19 and slowly inserts the front end of the water delivery pipe 19 into the port of the water inlet pipe 12. Then, the operator releases the sliding sleeve 14, and the compressed spring 16 instantly releases its elasticity, pushing the sliding sleeve 14 to quickly rebound outward. As the sliding sleeve 14 moves outward, its inner wall pushes the ball bearing 18 into the deepest part of the sliding groove 17. At this point, the water delivery pipe 19 is fixed inside the water inlet pipe 12. The fixing process of the water delivery pipe 20 is also the same, ensuring that the entire water delivery system is tightly connected and leak-proof.

[0038] Working principle: In the process of using the anti-settling equipment for water-based coating production, first connect the water supply pipe 19 and the water delivery pipe 20. Hold the sliding sleeve 14 and push it inward. Then, hold the water supply pipe 19 and insert its front end into the water inlet pipe 12. After that, release the sliding sleeve 14 so that it moves outward under the action of the spring 16. At the same time, its inner wall pushes the ball bearing 18 into the deepest part of the sliding groove 17 to fix the water supply pipe 19 inside the water inlet pipe 12. The water delivery pipe 20 is fixed in the same way as the water supply pipe 19, thereby connecting the water supply pipe 19 and the water delivery pipe 20. 0 is fixed inside the water inlet pipe 12 and the water outlet pipe 13. Then, water is introduced into the temperature control pipe 6 to keep the temperature inside the mixing tank 1 at the required temperature. Then, water-based paint is introduced into the mixing tank 1 through the feed pipe 2. Then, the motor 5 is started to drive the rotating shaft 7 to start rotating, so that the stirring blade 8 starts to stir the water-based paint inside. At the same time, the connecting strips 9 and 11 at both ends of the rotating shaft 7 drive the soft scraper 10 to rotate simultaneously, scraping off the paint adhering to the inner wall of the mixing tank 1 to prevent it from settling.

[0039] 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.
