Description

Technical Field

[0001] This utility model relates to the field of water-based pigment preparation, specifically a high-efficiency dispersion device for water-based pigment preparation. Background Technology

[0002] Water-based road marking pigments are high-performance coloring materials specifically designed for water-based road marking paints. They are primarily used for marking lane lines, pedestrian crossings, parking spaces, and other road surface markings. Their core components include high-purity pigments (such as titanium dioxide, iron oxide-based pigments, or environmentally friendly organic pigments), water-based resins, dispersants, and stabilizers to ensure vibrant, long-lasting colors that meet environmental standards. These pigments must possess excellent weather resistance, abrasion resistance, and UV resistance to withstand the harsh environment of prolonged exposure to sunlight, rain, and vehicle traffic. Water-based pigments require dispersion and mixing using a dispersion device during preparation.

[0003] For example, patent announcement number CN210905801U discloses a high-efficiency mixing and dispersing device for color paste, including a mixing tank, a mixing motor, and a stirrer. The mixing tank has an inlet and an outlet at its top and bottom, respectively. The stirrer is installed inside the mixing tank and is driven by the mixing motor, which is mounted on top of the mixing tank. The stirrer includes a mixing shaft and a mixing paddle. A baffle plate is provided on the side of the mixing paddle opposite the mixing shaft. This invention has a simple structure. The baffle plate around the mixing paddle prevents material from contacting the inner wall of the mixing tank, completely avoiding damage to the inner wall caused by material adhering to it. Simultaneously, the baffle plate rotates with the mixing shaft, making it less likely for material to adhere to it, significantly improving the mixing and dispersing effect. Furthermore, the baffle plate uses two arc-shaped units, facilitating installation and disassembly, allowing for repair or replacement based on the actual degree of damage, saving costs and making it convenient and practical.

[0004] However, the above-mentioned technologies cannot effectively disperse and mix the color paste evenly using only a stirring paddle. The color paste is prone to agglomeration during stirring, which affects the uniformity of the color paste preparation. Therefore, the market urgently needs to develop a high-efficiency dispersion device for water-line color paste preparation to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency dispersion device for preparing water-based color pastes, in order to solve the problem mentioned in the background art that it is difficult to effectively disperse and stir the color paste evenly by using only a stirring paddle, and the color paste is prone to agglomeration during stirring, which affects the uniformity of color paste preparation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency dispersion device for preparing water-based color paste, comprising an upper tank, a conical lower tank connected to the lower end of the upper tank, a first limiting tube fixedly connected to the middle of the upper part of the upper tank, a stirring shaft rotatably connected to the lower end of the first limiting tube, L-shaped stirring rods fixedly connected to both sides of the lower end of the stirring shaft and inside the upper tank, the lower end of the stirring shaft extending into the interior of the conical lower tank and fixedly connected to a spiral lifting blade, a second limiting tube fixedly connected to one side of the middle of the upper part of the upper tank, a dispersion shaft rotatably connected to the lower end of the second limiting tube, and multiple dispersion discs fixedly connected at equal intervals to the lower end of the dispersion shaft and inside the upper tank, each dispersion disc having multiple oblique rectangular plates fixedly connected in a ring array on its outer wall.

[0009] Preferably, a first driving device is fixedly connected to the middle of the upper end face of the upper tank, and a first driving motor is fixedly installed inside the first driving device.

[0010] Preferably, the upper end of the stirring shaft extends through the first limiting tube into the interior of the first driving device and is connected to the output shaft of the first driving motor via a reducer.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, a collaborative working mode of low-speed stirring and high-speed dispersion and reverse rotation is adopted. The L-shaped stirring rod and spiral lifting blades realize the full-area circulation stirring of the material. At the same time, the multi-layer dispersion disk and its oblique rectangular plate form a high-intensity shear force field, which effectively solves the problem of easy agglomeration in the traditional single stirring method and significantly improves the dispersion uniformity of the color paste.

[0015] (2) In this utility model, the innovative oblique rectangular plate design generates strong turbulence and local negative pressure effect when rotating at high speed. Combined with the forced circulation function of the spiral lifting blade, the material forms a three-dimensional flow in the device, realizing mixing without dead angles and greatly improving product quality.

[0016] (3) In this utility model, a modular design is adopted. The upper tank and the conical lower tank can be quickly separated through the connecting ring and bolt connection structure, which facilitates the cleaning and maintenance of the equipment. At the same time, each functional component adopts an independent drive design, which can flexibly adjust the working parameters of stirring and dispersing according to process requirements, thereby improving the applicability and efficiency of the equipment.

[0022] 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.

[0023] Please see Figure 1-4This utility model provides an embodiment of a high-efficiency dispersion device for preparing water-based color paste, comprising an upper tank 1, a feeding pipe 104 fixedly connected to one side of the middle of the upper end face of the upper tank 1, a conical lower tank 2 connected to the lower end of the upper tank 1, a discharge pipe 204 fixedly connected to the middle of the lower end of the conical lower tank 2, a discharge valve 205 fixedly connected to the lower end of the discharge pipe 204, the water-based color paste raw material being added into the upper tank 1 and the conical lower tank 2 through the feeding pipe 104, a first limiting pipe 102 fixedly connected to the middle of the upper end of the upper tank 1, a stirring shaft 3 rotatably connected to the lower end of the first limiting pipe 102, L-shaped stirring rods 301 fixedly connected to both sides of the lower end of the stirring shaft 3 and inside the upper tank 1, the lower end of the stirring shaft 3 extending into the interior of the conical lower tank 2 and fixedly connected to a spiral lifting blade 302, the stirring shaft 3 synchronously driving the L-shaped stirring rods 301 and the spiral lifting blade 302 to rotate slowly, the spiral lifting blade When plate 302 rotates, it lifts the raw material inside the conical lower tank 2 upwards, causing the raw material inside the upper tank 1 and the conical lower tank 2 to circulate. At the same time, the raw material is stirred by L-shaped stirring rod 301. A second limiting tube 103 is fixedly connected to one side of the middle of the upper end of the upper tank 1. A dispersing shaft 4 is rotatably connected to the lower end of the second limiting tube 103. Multiple dispersing discs 401 are fixedly connected at equal intervals to the lower end of the dispersing shaft 4 inside the upper tank 1. Multiple oblique rectangular plates 402 are fixedly connected in a ring array on the outer wall of each dispersing disc 401. While the raw material is being stirred, the dispersing shaft 4 synchronously drives the multiple dispersing discs 401 to rotate in the opposite direction to the rotation of the stirring shaft 3. When the multiple dispersing discs 401 rotate, they drive the multiple oblique rectangular plates 402 to rotate at high speed. The multiple oblique rectangular plates 402 are used to efficiently disperse the circulating raw material to prevent agglomeration, improve the dispersion efficiency of the raw material, and thus improve the uniformity of the mixing of the raw material.

[0024] Please see Figure 2 and Figure 3 The lower end of the upper tank 1 is fixedly connected to a first connecting ring 101, and the upper end of the conical lower tank 2 is fixedly connected to a second connecting ring 201. A sealing ring 202 is provided between the second connecting ring 201 and the first connecting ring 101. The second connecting ring 201 and the first connecting ring 101 are fixedly connected by multiple bolts 203. The conical lower tank 2 can be separated from the lower end of the upper tank 1 by removing multiple bolts, which facilitates the cleaning and maintenance of the upper tank 1 and the conical lower tank 2.

[0025] Please see Figure 2 A first driving device 5 is fixedly connected to the middle of the upper end face of the upper tank 1. A first driving motor 501 is fixedly installed inside the first driving device 5. The upper end of the stirring shaft 3 extends through the first limiting tube 102 into the interior of the first driving device 5 and is connected to the output shaft of the first driving motor 501 through a reducer. The stirring shaft 3 is driven to rotate slowly by the first driving motor 501.

[0026] Please see Figure 2 A second drive device 6 is fixedly connected to the other side of the middle of the upper end face of the upper tank 1. A second drive motor 601 is fixedly installed inside the second drive device 6. The upper end of the dispersing shaft 4 passes through the second limiting tube 103 and extends into the interior of the second drive device 6 and is connected to the output shaft of the second drive motor 601 through a coupling. The second drive motor 601 drives the dispersing shaft 4 to rotate at high speed.

[0027] Working Principle: During use, the water-based pigment raw material is injected into the mixing chamber formed by the upper tank 1 and the conical lower tank 2 through the feeding pipe 104. The first drive motor 501 drives the stirring shaft 3 to rotate slowly through the reducer, driving the L-shaped stirring rod 301 to perform basic stirring. At the same time, the spiral lifting blades 302 continuously lift the raw material at the bottom, forming a strong circulating flow. Simultaneously, the second drive motor 601 drives the dispersion shaft 4 to rotate in the opposite direction at high speed, driving the multi-layer dispersion disc 401 and its inclined rectangular plates 402 to apply high-intensity shear force to the material. The special tilt angle design of the inclined rectangular plates 402 generates strong turbulence and local negative pressure during high-speed rotation, effectively breaking up pigment agglomerates. Combined with the all-area stirring effect of the L-shaped stirring rod 301, it achieves mixing without dead corners. This working mode of low-speed stirring and high-speed dispersion working in opposite directions forms a unique composite shear force field, enabling efficient dispersion of the pigment. The device adopts a modular design, connected by bolts 203 to the first connecting ring 101 and the second connecting ring 201, facilitating quick disassembly, cleaning, and maintenance. Finally, the uniformly dispersed high-quality pigment is controlled to be output through the discharge valve 205.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
