Description

Technical Field

[0001] This utility model relates to the field of coating processing technology, and in particular to a dispersing device for water-based coatings. Background Technology

[0002] Water-based coatings have lower viscosity than other types of coatings, making them easier to disperse when using dispersion equipment. However, the dispersion process of water-based coatings requires higher standards of technology to ensure that the dispersion effect meets the application requirements of the water-based coating.

[0003] Existing dispersion equipment uses a lifting device to move the motor vertically, allowing the rotating rod at the motor output end to penetrate into the container holding the coating. The motor drives the rotating rod to stir the coating, thus dispersing it. However, during the process, the coating will agitate each other, creating unpredictable flow states such as vortices. Water-based coatings are more likely to introduce and retain air bubbles. If the flow state of the coating is too complex during dispersion, a large number of air bubbles will enter the interior of the coating, which will seriously affect the performance and stability of the coating. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a dispersion device for water-based coatings, which solves the problem that air bubbles are trapped and retained during the dispersion process of water-based coatings, affecting the final performance of the coatings.

[0005] The technical solution of this utility model is as follows: it includes a motor connected to a lifting device, a rotating rod at the bottom of the motor, a stirring tank on the surface of the rotating rod, connecting plates at intervals at the bottom of the stirring tank, a number of fins evenly spaced between two connecting plates, the fins forming an impeller-like structure at the bottom of the stirring tank, a baffle on one side of the top of the stirring tank, through grooves evenly spaced on the surface of the stirring tank near the baffle, and a blade on the side of the rotating rod inside the stirring tank, the rotation radius of the blade being adapted to the inner diameter of the stirring tank.

[0006] Furthermore, the connecting piece is an annular piece disposed on the surface of the mixing tank and a circular piece disposed at the bottom of the connecting piece, and the fins between the two connecting pieces are vertically connected downward to the circular connecting piece starting from the annular connecting piece.

[0007] Furthermore, the fins are several inclined plate-like structures, and the connection between the several fins and two connecting plates forms an impeller-like structure. The bottom surface of the connecting plate at the bottom is provided with spiral raised textures, so that the connecting plate can agitate the coating at the bottom of the container when it rotates, thus avoiding the formation of processing dead corners in the container.

[0008] Furthermore, the impeller-like structure formed by the fins, in its rotating state, conveys the coating material along the outer casing of the mixing tank and inside the mixing tank, so that the coating material in the container circulates within the mixing tank during the flow process.

[0009] Furthermore, the diameter of the annular connecting piece is smaller than that of the circular connecting piece, wherein the width of the annular connecting piece is adapted to the width of the fin in its inclined state and the edges are flush.

[0010] Furthermore, the baffle surrounds the top of the mixing tank and is an overall downward-curved arc-shaped plate structure. A through groove is opened on the surface of the mixing tank covered by the curved baffle to restrict the flow direction of the paint discharged from the mixing tank and prevent the paint from flowing horizontally and causing turbulence.

[0011] Furthermore, the impeller is conveyed from bottom to top, ensuring that the coating can be conveyed upward along the mixing tank.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention involves submerging the entire mixing tank inside the coating container and rotating it. The impeller-like structure at the bottom of the mixing tank, composed of fins, draws the coating from the container into the mixing tank during agitation. Due to the characteristics of the impeller structure, the coating continuously flows into the mixing tank, causing the coating already in the mixing tank to be transported upwards. As it passes the impeller blades, it is agitated again and continues to be transported upwards under the action of the impeller blades. The coating that moves to the top of the mixing tank returns to the container through a channel until it enters the next cycle. Throughout the entire process, the mixing and turbulence of the coating occur within the mixing tank. The coating leaving the mixing tank flows downwards due to the obstruction of the baffle. The coating in the container always maintains a circulating flow in the manner of passing through the mixing tank, preventing the formation of vortices or other flow states on the surface of the coating, thereby eliminating the possibility of the coating trapping and retaining air bubbles.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figure 1-3 As shown, a dispersion device for water-based coatings includes a motor 1 connected to a lifting device, a rotating rod 2 at the bottom of the motor 1, a mixing tank 3 on the surface of the rotating rod 2, connecting plates 4 spaced apart at the bottom of the mixing tank 3, and a plurality of fins 5 evenly spaced between two connecting plates 4. The connecting plates 4 are annular plates on the surface of the mixing tank 3 and circular plates at the bottom of the connecting plates 4. The fins 5 between two connecting plates 4 are vertically connected to the circular connecting plates 4 from the annular connecting plates 4 as the starting point. The diameter of the annular connecting plate 4 is smaller than that of the circular connecting plate 4. The width of the annular connecting plate 4 is adapted to the width of the fins 5 in the inclined state and the edges are flush. The fins 5 are a plurality of inclined plate-like structures. The plurality of fins 5 are connected with the two connecting plates 4 to form an impeller-like structure. The bottom surface of the connecting plate 4 at the bottom is provided with spiral raised textures so that the connecting plate 4 can agitate the coating at the bottom of the container when rotating, avoiding the formation of processing dead corners in the container.

[0020] The fins 5 form an impeller-like structure at the bottom of the mixing tank 3. When the impeller-like structure formed by the fins 5 is rotating, the conveying direction is along the outer box of the mixing tank 3 and inside the mixing tank 3, so that the paint in the container circulates in the mixing tank 3 during the flow process. A baffle 6 is provided on one side of the top of the mixing tank 3. Through grooves 7 are evenly spaced on the side of the surface of the mixing tank 3 near the baffle 6. The baffle 6 surrounds the top of the mixing tank 3 and is an arc-shaped plate structure that bends downward. The through grooves 7 are opened on the surface of the mixing tank 3 covered by the bend of the baffle 6, which restricts the flow direction of the paint discharged along the mixing tank 3 and avoids the paint from flowing in the horizontal direction and causing turbulence. A blade 8 is provided on one side of the rotating rod 2 inside the mixing tank 3. The rotation radius of the blade 8 is adapted to the inner diameter of the mixing tank 3. The conveying direction of the blade 8 is from bottom to top, ensuring that the paint can be conveyed upward along the mixing tank 3.

[0021] The working principle of this utility model is as follows: First, the lifting device drives the motor 1 to move vertically, so that the rotating rod 2 located at the output end of the motor 1 can enter or leave the container holding the paint. When the rotating rod 2 enters the container, the operator ensures that the mixing tank 3 is completely immersed in the paint. Then, the motor 1 is started, and the motor 1 drives the mixing tank 3 to rotate through the rotating rod 2. During the rotation, the impeller-like structure formed by the fins 5 at the bottom of the mixing tank 3 can draw the paint in the container into the mixing tank 3. The paint will be continuously conveyed into the mixing tank 3, and the paint that has entered the mixing tank 3 will be pushed upward through the blades 8. When passing through the blades 8, it will be agitated again and continue to be conveyed upward under the action of the blades 8. When the paint is conveyed to the top of the mixing tank 3, it will return to the container through the channel 7 until it enters the next cycle. The dispersion process of the paint is completed in the process of circulation. The entire dispersion process is carried out inside the mixing tank 3. Therefore, the paint outside the mixing tank 3 and the paint surface will not have a complicated liquid flow state, avoiding the paint from carrying gas into the paint and generating bubbles during the flow process.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
