Description

Technical Field

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

[0002] Water-based coatings are environmentally friendly coatings that use water as a solvent or dispersion medium. Homogenization plays a crucial role in the production of water-based coatings. It ensures that the various components in the coating (such as resins, pigments, fillers, and additives) are uniformly mixed, avoiding phenomena such as layering, sedimentation, or particle agglomeration, thereby improving the stability, application performance, and final film quality of the coating.

[0003] In existing technologies, when water-based coatings are discharged after homogenization, some of the coating adheres to the inner wall of the equipment and the mixing rack due to its adhesive properties, making it difficult for it to fall off and resulting in waste.

[0004] Therefore, we propose a homogenization device for water-based coatings. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where, after homogenization, some water-based coatings adhere to the inner wall of the equipment and the mixing rack due to their adhesive properties, resulting in waste. Therefore, this invention proposes a water-based coating homogenization device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A water-based coating homogenizing device, comprising:

[0008] The tank has a rotating shaft that rotatably passes through its surface. Multiple stirring rods are circumferentially distributed at one end of the rotating shaft that extends into the interior of the tank. The upper and lower end faces of the stirring rods are arc-shaped, and the bottom end of the rotating shaft is conical.

[0009] The cleaning assembly includes a cleaning ring that slides against the inner wall of the tank. A radially extending cleaning plate is fixedly connected to the inner side of the cleaning ring. The cleaning plate has a shaft hole that fits with the shaft clearance and a clearance hole for accommodating the stirring rod. The surface of the cleaning plate is provided with cleaning parts that slide radially thereon.

[0010] The lifting drive assembly is symmetrically arranged on both sides of the tank and connected to the cleaning ring drive.

[0011] The rotary drive assembly is fixedly installed outside the tank and connected to the rotating shaft for transmission.

[0012] In one possible design, the cleaning component includes a slider that is slidably disposed in a groove on the surface of the cleaning plate, a C-shaped cleaning block that is fixedly connected to the end of the slider, a plurality of tension springs that are fixedly disposed on one side of the inner wall of the cleaning block and one side of the cleaning plate, and a guide surface that matches the profile of the rotating shaft on one side of the cleaning block.

[0013] In one possible design, the lifting drive assembly includes an electric push rod fixedly mounted on the outer wall of the tank, the output end of which is connected to a lifting rod passing through the tank wall, and the end of the lifting rod is fixedly connected to a cleaning ring.

[0014] In one possible design, the rotary drive assembly includes a mounting base fixed to the top of the tank, on which a motor is fixed, the output shaft of the motor being coaxially connected to the rotating shaft.

[0015] In one possible design, both the cleaning ring and the cleaning block have inclined guide surfaces at their bottoms, and the bottom edge of the cleaning block has a guide arc surface.

[0016] In one possible design, the tank has a feed inlet at the top and a discharge outlet with a control valve at the bottom, and the portion of the rotating shaft inside the tank has a clearance groove.

[0017] In one possible design, the bottom of the tank is provided with a plurality of support legs evenly distributed around its circumference, and the support legs are fixedly connected to the bottom surface of the tank.

[0018] In this application, during use, the material is fed into the tank through the inlet, and then the motor is started. The motor drives the rotating shaft and stirring rod to rotate, thereby stirring and homogenizing the material. After homogenization, the control valve on the outlet is opened to allow the material to flow out and fall into the pre-prepared collection device. Then, the electric push rod is started to drive the lifting rod and cleaning ring to descend. The cleaning ring cleans the inner wall of the tank, and the cleaning ring drives the cleaning plate and cleaning block to descend. With the cooperation of the shaft hole and the guide curved surface, the outer wall of the rotating shaft is cleaned. During the descent, the cleaning block is separated after hitting the stirring rod, so that the cleaning block cleans the outer wall of the stirring rod. At the same time, under the guidance of the guide surface, the material is guided to flow down the outer wall of the rotating shaft. As a result, the material attached to the inner wall of the tank and the outer wall of the rotating shaft and stirring rod can be discharged from the tank, thereby reducing material waste.

[0019] Beneficial effects: In this utility model, the water-based coating homogenizing device, through the arrangement of multiple structures such as cleaning ring, cleaning plate and cleaning block, can clean the inner wall of the tank and the outer wall of the rotating shaft and cleaning rod, and guide the cleaned material out, reducing material waste;

[0020] In this utility model, the water-based coating homogenizing device, by setting a clearance groove, can provide clearance for the cleaning plate when the rotating shaft rotates, which facilitates the rotation of the rotating shaft and reduces wear caused by structural friction.

[0021] In this invention, the inner wall of the tank and the outer wall of the rotating shaft and cleaning rod can be cleaned, and the cleaned material can be guided out, reducing material waste. It can also make way for the cleaning plate when the rotating shaft rotates, making it easier for the rotating shaft to rotate, while reducing wear caused by structural friction.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0031] Example 1: Refer to Figures 1-4 A homogenizing apparatus, comprising:

[0032] The tank body 1 has a rotating shaft 9 rotatably inserted on its surface. Multiple stirring rods 10 are circumferentially distributed at one end of the rotating shaft 9 extending into the interior of the tank body 1. The upper and lower end faces of the stirring rods 10 are arc-shaped. This arc-shaped structure can reduce the uneven shear force on the water-based coating during the stirring process, while reducing the resistance between the stirring rods 10 and the coating, improving the stirring efficiency, and facilitating its use in conjunction with the subsequent guiding arc surface 22. The bottom end of the rotating shaft 9 is conical.

[0033] The cleaning assembly includes a cleaning ring 11 that slides against the inner wall of the tank 1. A radially extending cleaning plate 12 is fixedly connected to the inner side of the cleaning ring 11. The cleaning plate 12 has a shaft hole 13 that fits with the rotating shaft 9 and a clearance hole 14 that accommodates the stirring rod 10. The shaft hole 13 ensures that the rotating shaft 9 can pass smoothly through the cleaning plate 12, and the clearance hole 14 allows the stirring rod 10 to pass through. The surface of the cleaning plate 12 is provided with a cleaning component that slides radially thereal. The cleaning component includes a slider 17 that is slidably disposed in a groove 18 on the surface of the cleaning plate 12. A C-shaped cleaning block 15 is fixedly connected to the end. Multiple tension springs 16 are fixedly provided on one side of the inner wall of the cleaning block 15 and one side of the cleaning plate 12. A guide surface 21 matching the contour of the rotating shaft 9 is provided on one side of the cleaning block 15. When the cleaning assembly moves up and down, when the cleaning block 15 is combined, the guide surface 21 and the outer wall of the rotating shaft 9 are in contact, thereby cleaning the material on the outer wall of the rotating shaft 9. When the cleaning block 15 is separated by the stirring rod 10, the tension spring 16 can pull the cleaning block 15 to move against the outer wall of the stirring rod 10, thereby cleaning the outer wall of the stirring rod 10.

[0034] The lifting drive assembly is symmetrically arranged on both sides of the tank 1 and is connected to the cleaning ring 11. The lifting drive assembly includes an electric push rod 3 fixedly installed on the outer wall of the tank 1. The output end of the electric push rod 3 is connected to a lifting rod 4 that passes through the wall of the tank 1. The end of the lifting rod 4 is fixedly connected to the cleaning ring 11. When the electric push rod 3 is working, its output end drives the lifting rod 4 to move up and down, thereby driving the cleaning ring 11 to slide up and down along the inner wall of the tank 1, realizing the lifting movement of the cleaning assembly.

[0035] A rotary drive assembly is fixedly installed outside the tank body 1 and is connected to the rotating shaft 9 for transmission. The rotary drive assembly includes a mounting base 5 fixed to the top of the tank body 1. A motor 6 is fixed on the mounting base 5. The output shaft of the motor 6 is coaxially connected to the rotating shaft 9. When the motor 6 is working, its output shaft drives the rotating shaft 9 to rotate, thereby driving the stirring rod 10 to stir and homogenize the water-based coating in the tank body 1.

[0036] This application can be used in the field of water-based coatings, or in other fields applicable to this application.

[0037] Example 2: An improved water-based coating homogenizing device based on Example 1, which is applied to the field of water-based coatings;

[0038] In one aspect of this embodiment, both the cleaning ring 11 and the cleaning block 15 have inclined guide surfaces 20 at their bottoms. The guide surfaces 20 can guide the cleaned paint to flow downwards, preventing the paint from accumulating at the bottom of the cleaning ring 11 and the cleaning block 15. The bottom edge of the cleaning block 15 has a guide arc surface 22, which can cooperate with the stirring rod 10 to facilitate the stirring rod 10 in pushing the cleaning block 15 to move.

[0039] In one aspect of this embodiment, the tank 1 has an inlet 7 at the top and an outlet 8 with a control valve at the bottom. The control valve can control the opening and closing of the outlet 8. After homogenization, the control valve can be opened to discharge the homogenized water-based coating. The part of the rotating shaft 9 located inside the tank 1 is provided with a clearance groove 19 to provide clearance for the cleaning plate 12, so as to facilitate the rotation of the rotating shaft 9 and avoid friction between the cleaning plate 12 and the rotating shaft 9 when it rotates.

[0040] In one aspect of this embodiment, a plurality of support legs 2 are evenly distributed around the bottom of the tank 1. The support legs 2 are fixedly connected to the bottom surface of the tank 1 to provide stable support for the tank 1 and ensure the stability of the device during operation.
