Description

Technical Field

[0001] The utility model relates to the technical field of water-based paint mixing, in particular to an anti-bubbling water-based paint mixing can. Background Art

[0002] Water-based paint uses water as a solvent, saving significant resources, eliminating fire hazards during construction, and reducing air pollution. It uses only small amounts of low-toxic alcohol-ether organic solvents, improving the working environment. While typical water-based paints contain between 5% and 15% organic solvents, cathodic electrophoretic coatings have reduced this to less than 1.2%, significantly reducing pollution and conserving resources.

[0003] Chinese patent publication number CN216572564U discloses an anti-foaming water-based paint mixing tank, which stores mixed materials through a larger upper shell and mixes paint in a smaller diameter mixing chamber at the bottom. The fluid is mixed in the mixing chamber at the bottom, reducing the contact with the upper air during the fluid rotation and mixing, thereby reducing bubbles. The upper shell has a larger diameter, and the upper fluid rotates at a slow rate, producing fewer bubbles when in contact with the air. The rotating shaft drives multiple groups of mixing rods at the lower end to mix multiple materials, and the inclined mixing rods provide a larger bottom disturbance, allowing the materials to be fully mixed in the mixing chamber.

[0004] However, compared with the existing technology and comparative documents, in the process of mixing the existing water-based paint, multiple raw materials are fed into the tank and stirred to mix them evenly. During the stirring process, defoaming is achieved by the shear force of the rotating blades on the foam and the impact force of the foam hitting the wall of the container. However, the high-speed rotation of the rotating blades will cause foam to reappear in the water-based paint, thereby reducing the quality of the water-based paint. Utility Model Content

[0005] The main purpose of the utility model is to provide a water-based paint mixing can which can prevent bubbling.

[0006] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0007] A foaming-proof water-based paint mixing tank comprises a tank body, a top cover is installed on the top of the tank body, a stirring mechanism is provided on the top cover, and the bottom end of the stirring mechanism is located in the tank body, and multiple groups of crushing mechanisms are installed below the outer side of the stirring mechanism;

[0008] Each crushing mechanism is provided with three crushing components in the vertical direction. The thickness of the three crushing components decreases from bottom to top. The two crushing components at the top are rotatably connected to the stirring mechanism, and the crushing components at the bottom are fixedly connected to the stirring mechanism. There are movable components between the crushing components.

[0009] The movable component includes a base located between the two groups of crushing components, and the base is fixedly connected to the crushing component located below it. A connecting block is slidably connected inside the base, and the top of the connecting block is fixedly connected to the crushing component located above. A guide rod passes through the connecting block, and the connecting block is slidably connected to the guide rod, and one end of the connecting block is connected to the inner wall of the base through a reset spring.

[0010] Preferably, the crushing assembly includes a shaft sleeve connected to the stirring mechanism, and a crushing plate is fixed to the outside of the shaft sleeve.

[0011] Preferably, a capture zone, an aggregation zone and a discharge zone are sequentially opened in the crushing plate, and the opening end of the capture zone has the same rotation direction as the stirring mechanism, and the thickness of the aggregation zone and the discharge zone is smaller than that of the capture zone.

[0026] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0027] like Figures 1-6 As shown, the present embodiment provides an anti-foaming water-based paint mixing can, comprising a can body 1, a top cover 2 installed on the top of the can body 1, the top cover 2 can seal the top of the can body 1, a stirring mechanism 3 is provided on the top cover 2, and the bottom end of the stirring mechanism 3 is located inside the can body 1, and multiple groups of crushing mechanisms 4 are installed below the outside of the stirring mechanism 3;

[0028] Each set of crushing mechanisms 4 is provided with three sets of crushing components 41 in the vertical direction. The crushing components 41 can stir, mix and defoam the water-based paint. The thickness of the three sets of crushing components 41 decreases from bottom to top. The two sets of crushing components 41 at the top are both rotatably connected to the stirring mechanism 3, and the crushing components 41 at the bottom are fixedly connected to the stirring mechanism 3. A movable component 42 is connected between each pair of crushing components 41.

[0029] The movable component 42 includes a base 4201 located between the two groups of crushing components 41, and the base 4201 is fixedly connected to the crushing component 41 located below it. A connecting block 4202 is slidably connected inside the base 4201. The connecting block 4202 can be connected to the adjacent crushing component 41, and the top of the connecting block 4202 is fixedly connected to the crushing component 41 located above. A guide rod 4203 runs through the connecting block 4202, and the guide rod 4203 can guide the connecting block 4202. The connecting block 4202 is slidably connected to the guide rod 4203, and one end of the connecting block 4202 is connected to the inner wall of the base 4201 through a reset spring 4204. After use, the reset spring 4204 can drive the crushing component 41 to reset through the connecting block 4202.

[0030] like Figure 2-Figure 3 As shown, the crushing assembly 41 includes a sleeve 4101 connected to the stirring mechanism 3, the sleeve 4101 can connect the support shaft 303 and the crushing assembly 41, and a crushing plate 4102 is fixed to the outside of the sleeve 4101, and the crushing plate 4102 can contact the water-based paint to stir and mix it.

[0031] like Figure 4 and Figure 6 As shown, the crushing plate 4102 is sequentially provided with a capture area 4103, an aggregation area 4104 and a discharge area 4105, and the open end of the capture area 4103 has the same rotation direction as the stirring mechanism 3, and the thickness of the aggregation area 4104 and the discharge area 4105 is smaller than that of the capture area 4103. During the stirring and mixing process, the water-based paint passes through the capture area 4103 and the aggregation area 4104, and then is captured, aggregated and destroyed, and the remaining liquid is discharged from the discharge area 4105.

[0032] like Figure 2 and Figure 6 As shown, crushing nets 4106 are installed at the connecting parts of the collection area 4103, the gathering area 4104 and the discharge area 4105 in the crushing plate 4102. When the water-based paint moves along the collection area 4103, the gathering area 4104 and the discharge area 4105, the crushing nets 4106 can filter and compress the paint layer by layer to optimize the defoaming effect.

[0033] like Figure 1-Figure 2 As shown, the stirring mechanism 3 includes a mounting base 301 fixed on the top cover 2, the mounting base 301 can support the motor 302, the motor 302 is fixed on the top of the mounting base 301, the motor 302 can drive the support shaft 303 to rotate, and the output end of the motor 302 is installed with a support shaft 303, the support shaft 303 can drive the crushing mechanism 4 to rotate, and the support shaft 303 passes through the mounting base 301 and the top cover 2.

[0034] like Figure 1-Figure 2As shown, the outer side of the bottom of the support shaft 303 is connected to a support frame 5 through a bearing. The support frame 5 can support the bottom end of the support shaft 303, and the support frame 5 is fixedly connected to the tank body 1.

[0035] like Figure 1 As shown, an exhaust pipe 6 is connected to one side of the top cover 2, and the gas exhausted in the water-based paint is discharged from the tank body 1 through the exhaust pipe 6. A feed pipe 7 is installed on one side wall of the tank body 1, and the water-based paint raw materials enter the tank body 1 through the feed pipe 7. A discharge pipe 8 is connected to the middle part of the bottom end of the tank body 1, and the water-based paint after stirring, mixing and defoaming is discharged from the tank body 1 through the discharge pipe 8.

[0036] Working principle of this device: When this device is used, the top cover 2 can seal the top of the tank body 1, and the water-based paint raw material enters the tank body 1 through the feeding pipe 7. After the feeding is completed, the motor 302 on the top of the mounting seat 301 drives the support shaft 303 to rotate, and the support shaft 303 drives the crushing mechanism 4 to stir and mix the water-based paint, and the support frame 5 supports the bottom of the support shaft 303;

[0037] During the stirring and mixing process, the crushing component 41 in the crushing mechanism 4 contacts the water-based paint and drives it to flow and mix. During the mixing process, the water-based paint enters the crushing plate 4102 and is sequentially captured in the collection area 4103 and the gathering area 4104. After being captured, gathered and destroyed, the remaining liquid is discharged from the discharge area 4105. At the same time, as the water-based paint moves along the collection area 4103, the gathering area 4104 and the discharge area 4105, it is filtered and compressed layer by layer through the crushing net 4106, thereby optimizing the defoaming effect.

[0038] And when the crushing component 41 stirs, mixes and defoams the water-based paint, since the thickness of the three groups of crushing components 41 decreases from top to bottom, there is a difference in the resistance of each group of crushing components 41 to the water-based paint, so that the three groups of crushing components 41 can move along the guide rod 4203 in the base 4201 through the connecting block 4202 and be staggered in the vertical direction. When the water-based paint passes through the crushing component 41, the staggered crushing component 41 can generate shear force on the bubbles in the water-based paint, thereby improving the defoaming effect and avoiding the appearance of bubbles in the water-based paint. After use, the connecting block 4202 is reset by the reset spring 4204 to facilitate subsequent use. After mixing is completed, the water-based paint is discharged from the tank body 1 through the discharge pipe 8.

[0039] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention based on the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
