Description

Technical Field

[0001] This utility model relates to the field of paint processing technology, specifically to a continuous paint production device. Background Technology

[0002] Paint is a chemical mixture that adheres firmly to the surface of an object, serving protective, decorative, marking, and other special purposes. A paint is a material that can be applied to the surface of an object using different application techniques to form a firmly adhering, continuous solid film with a certain strength. This film is commonly called a coating film, also known as a paint film or coating layer. Paint generally consists of four parts: film-forming substances, fillers (pigments and fillers), solvents, and additives. The composition may vary slightly depending on performance requirements; for example, varnishes may not contain pigments and fillers, and powder coatings may not contain solvents. It belongs to organic chemical polymer materials, and the resulting coating film is a type of polymer compound. According to the modern classification of chemical products, paint belongs to fine chemical products. Modern paints are gradually becoming a multifunctional engineering material and an important sector within the chemical industry.

[0003] In the paint production process, various paint raw materials need to be diluted, tinted, and stirred to ensure the uniformity of the paint color. Existing new paint production dilution and stirring kettles require continuous feeding and discharging during the paint production process, which is not suitable for large-scale production and results in low production efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a continuous paint production device, which includes:

[0005] A mixing tank, wherein a discharge pipe is connected to the bottom of one end of the mixing tank;

[0006] A rotating shaft is located inside the mixing tank; multiple stirring blades are fixedly mounted on the rotating shaft.

[0007] A rotary drive component is connected to a rotary shaft extending from the end of the mixing tank, and the rotary drive component is used to drive the rotary shaft to rotate.

[0008] The end of the rotating shaft away from the discharge pipe extends out of the mixing tank and is coaxially and fixedly connected to a spiral blade. The spiral blade rotates in a sealed manner inside the feed conveying pipe, and a hopper is fixedly connected to the feed conveying pipe.

[0009] One end of the rotating shaft is a hollow tubular structure. The rotating shaft has a feed port at one end of the feed conveying pipe, which is connected to the hollow tubular structure. The other end of the hollow tubular structure is fixedly connected to a discharge plate, which is located inside the mixing tank. The discharge plate has several feed holes.

[0010] Preferably, the mixing tank is a horizontally placed cylindrical structure.

[0011] Preferably, the mixing tank includes a cylindrical body and end caps. The cylindrical body has a cylindrical structure, and the end caps are fixed to both ends of the cylindrical body by fixing bolts.

[0012] Preferably, the stirring blades are inclined.

[0013] Preferably, the angle between the stirring blade and the cross section of the rotating shaft is 10 degrees to 30 degrees.

[0014] Preferably, an observation window is provided on the side wall of the mixing tank, and a packing hopper is connected to the mixing tank, with the observation window corresponding to the position of the packing hopper.

[0015] Preferably, there are two observation windows, including a first observation window and a second observation window. The position of the first observation window corresponds to the position of the filling hopper, and the position of the second observation window corresponds to the position of the discharge pipe.

[0016] Preferably, the rotating shaft where the feed port is located has a frustum-shaped structure, and the feed port is located on its inclined surface.

[0017] The technical effects and advantages of this utility model are as follows: The conveying process is achieved through the rotation of a spiral blade. Paint raw materials inside the hopper enter the hollow tube structure through the feed port and exit through the feed hole into the mixing tank. The paint raw materials are stirred by the spiral blade and driven by the hollow tube structure and the discharge plate, entering the mixing tank through the feed hole, thus completing the feeding drive and initial mixing. This completes the axial mixing of the paint raw materials within the pipeline, resulting in uniform and proportional mixing, and achieving automatic feeding. Mixing in a larger capacity mixing tank facilitates the mixing of paint liquids at different axial levels, allowing for further mixing and high production quality. Attached Figure Description

[0022] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims. Example

[0023] refer to Figures 1-3 This embodiment proposes a continuous paint production apparatus for continuous processing and production of paint. The continuous paint production apparatus may include:

[0024] The mixing tank 1 can be a horizontal or vertical cylindrical structure, with horizontal placement being preferred. The mixing tank 1 forms an internal space for paint mixing and agitation. It possesses a certain degree of sealing and rigidity to prevent deformation or paint leakage during operation. The mixing tank 1 includes a cylindrical body and end caps. The cylindrical body is fixed to both ends of the cylindrical body with bolts, allowing for a detachable connection and facilitating internal cleaning and component maintenance. A discharge pipe 2 can be connected to the bottom of one end of the mixing tank 1. A control valve is installed on the discharge pipe 2, allowing the paint liquid inside the mixing tank 1 to be discharged by opening the valve. The degree of valve opening controls the discharge speed (details omitted here). The mixing tank 1 can be fixedly mounted on a base 3 using a support frame. The base 3 can be a rectangular plate structure or a welded frame structure, increasing the stability of the mixing tank 1.

[0025] A rotating shaft 7 is rotatably mounted inside the mixing tank 1, its position coinciding with the axis of the mixing tank 1. The rotating shaft 7 can be positioned directly on the axis of the mixing tank 1, or, in the case of a horizontally positioned mixing tank 1, below its central axis (details omitted here). Multiple stirring blades 10 are fixedly mounted on the rotating shaft 7. These blades rotate with the shaft 7, stirring the paint liquid within the mixing tank 1 and causing it to churn. The mixing tank 1 can be filled to the brim with the paint liquid, in which case the rotating shaft 7 is positioned on the axis of the mixing tank 1. Alternatively, the mixing tank 1 can be partially filled with the paint liquid, in which case the rotating shaft 7 is positioned below the axis of the mixing tank 1. In this case, the paint liquid not only tumbles circumferentially but also mixes upwards, increasing the uniformity of the mixture. The stirring blades 10 can be tilted, their rotation facilitating the axial transport of the paint liquid within the mixing tank 1 and allowing it to drain from the discharge pipe 2. The angle between the stirring blade 10 and the section of the rotating shaft 7 can be 10 degrees to 30 degrees, which can prevent the paint liquid from being delivered too fast or too slow. The tilt angles of adjacent stirring blades 10 can be different, so that the axial delivery speed of the paint liquid at each position is different, thereby increasing the uniformity of axial mixing.

[0026] A rotation drive component 4 is connected to a rotating shaft 7 extending from the end of the mixing tank 1, and is used to drive the rotating shaft 7 to rotate at a constant speed. The rotation drive component 4 can rotate in both forward and reverse directions. The rotation drive component 4 may include a motor and a belt transmission structure. The motor may be a three-phase motor, which can be mounted on the mixing tank 1 or the base 3. The output shaft of the motor is coaxially fixedly connected to a pulley. One end of the rotating shaft 7 extends out of the mixing tank 1 and is coaxially fixedly connected to a pulley. The two pulleys are connected by a belt. Under the drive of the motor, the rotating shaft 7 can rotate at a constant speed. Of course, under normal circumstances, there will be no difference in the ingredients, but if there is a difference in the raw material ratio, it needs to be adjusted. An observation window 8 may be provided on the side wall of the mixing tank 1. The observation window 8 may be made of transparent glass, through which the color of the paint liquid inside the mixing tank 1 can be observed, so that the color of the paint liquid can be judged by experience. A filling hopper 9 may be provided at the corresponding position of the observation window 8, through which a colorant can be added into the mixing tank 1. The specific amount added can be obtained by experience, and will not be elaborated here. There are two observation windows 8, including a first observation window and a second observation window. The first observation window is located upstream of the filling hopper 9 in the conveying direction of the filling hopper 9. The second observation window is located upstream of the discharge pipe 2. The first observation window allows for a preliminary assessment of the paint liquid inside the mixing tank 1. Then, the color is adjusted by the filling hopper 9, and the toner enters the mixing tank 1 to mix with the paint liquid. After mixing, the second observation window can be used for confirmation. If the mixture is correct, the rotating shaft 7 continues to rotate, driving the paint in the mixing tank 1 to be discharged from the discharge pipe 2. If the paint liquid inside the filling hopper 9 is not mixed evenly or there is a color difference, the rotating shaft 7 can be driven in the reverse direction to rotate, thereby driving the paint liquid inside the mixing tank 1 to be driven in the reverse direction for mixing again. The second observation window can be used for confirmation again. If the mixture is qualified, the rotating shaft 7 continues to rotate in the forward direction to discharge the paint from the discharge pipe 2.

[0027] The rotating shaft 7 extends out of the mixing tank 1 from the end away from the discharge pipe and is coaxially fixedly connected to a spiral blade 14. The spiral blade 14 rotates in a sealed manner inside the feed conveying pipe 5, which can be fixedly connected to the mixing tank 1. A hopper 6 is fixedly connected to the feed conveying pipe 5. Specifically, the feed conveying pipe 5 can be a cylindrical structure. The rotating shaft 7 extends into the inside of the feed conveying pipe 5 through a shaft seal, and various paint liquid raw materials can be added into the hopper 6. One end of the rotating shaft 7 is a hollow tubular structure. A feed port 13 is opened at one end of the rotating shaft 7 in the feed conveying pipe 5. The feed port 13 is connected to the hollow tubular structure. A discharge plate 11 is fixedly connected to the other end of the hollow tubular structure. The discharge plate 11 is located inside the mixing tank 1 and has several feed holes 12. The number of discharge plates 11 can be set to multiple. The feed holes 12 can be linearly distributed on the discharge plates 11. The diameter of the feed holes 12 is 1-10mm, but other values ​​are not excluded. As the spiral blade 14 rotates, the paint material inside the hopper 6 is conveyed. The paint material enters the hollow tube structure through the feed port 13 and exits through the feed hole 12 into the mixing tank 1. The paint material is initially mixed by the stirring of the spiral blade 14 and the transmission of the hollow tube structure and the discharge plate 11. It then enters the mixing tank 1 through the feed hole 12. The discharge plate 11 rotates with the rotating shaft 7, facilitating uniform feeding of the paint material and making it easy to observe and judge through the first observation window. The rotating shaft 7 at the feed port 13 is a frustum-shaped structure, and the feed port 13 is set on its inclined surface to facilitate feeding. A controller may also be included, which is electrically connected to the rotating drive component 4. The controller can control the rotating drive component 4 to rotate at a constant speed.

[0028] During production, the paint raw materials to be mixed are added into the hopper 6 according to the production ratio, and the rotary drive 4 is activated by the controller. Driven by the rotary drive 4, the rotating shaft 7 and the spiral blade 14 rotate in the forward direction. As the spiral blade 14 rotates, the paint raw materials inside the hopper 6 are conveyed. The paint raw materials enter the hollow tube structure from the feed port 13 and exit into the mixing tank 1 from the feed hole 12. The paint raw materials are initially mixed by the stirring of the spiral blade 14 and the transmission of the hollow tube structure and the discharge plate 11. Entering the mixing tank 1 through the feed hole 12 facilitates uniform feeding of the paint raw materials. The mixed paint liquid is discharged from the discharge pipe 2.

For example, the steps described in this disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this disclosure can be achieved, and this is not limited herein.

[0030] The specific embodiments described above do not constitute a limitation on the scope of protection of this disclosure. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
