Description

Technical Field

[0001] This utility model belongs to the field of metal coating production equipment, specifically relating to a high-speed disperser for water-based metal coatings. Background Technology

[0002] A high-speed disperser for water-based metallic coatings is a device used to rapidly and uniformly disperse various components (such as pigments, resins, and additives) in water-based metallic coatings. It utilizes a high-speed rotating dispersion disc to generate strong shear and centrifugal forces, ensuring that solid particles (such as pigments) in the coating are well dispersed in the liquid medium (such as a mixture of water and resin). This prevents pigment agglomeration, ensuring stable coating quality, uniform color, and good hiding power and adhesion. It plays a crucial role in the production process of water-based metallic coatings, helping to improve production efficiency and product quality. Furthermore, its design is tailored to the characteristics of water-based coatings, avoiding any adverse effects on the water-based system.

[0003] During high-speed dispersion, the temperature of the coating increases due to the conversion of mechanical energy. For water-based metallic coatings, excessively high temperatures may cause water to evaporate too quickly, altering the coating's viscosity and solids content. Furthermore, some additives in water-based coatings may become ineffective at high temperatures. Therefore, it is crucial to control the temperature during the dispersion process. Utility Model Content

[0004] To address the problems and shortcomings of existing technologies, the purpose of this utility model is to provide a high-speed disperser for water-based metal coatings that can maintain the dispersion temperature, reduce the oxygen content of the coating, and prevent air bubbles in the coating. It also provides a variety of dispersion speeds and is suitable for dispersing different metal coatings.

[0005] A high-speed disperser for water-based metal coatings includes a cylinder and a dispersion disc. The dispersion disc is disposed inside the cylinder. The upper end of the cylinder is open, and a detachable cylinder cover is provided at the opening. The cylinder includes an inner cylinder and an outer cylinder. An interlayer is provided between the inner cylinder and the outer cylinder. The interlayer is filled with water and a heating rod is provided in the interlayer.

[0006] Furthermore, an acceleration gearbox is provided at the bottom of the cylinder. The acceleration gearbox contains a central gear and several acceleration gears. The central gear is equipped with a main shaft, which is connected to the dispersing disk and drives the dispersing disk to rotate. The acceleration gears are on the same plane as the central gear and are arranged around the central gear. Each acceleration gear has a different number of teeth.

[0007] Furthermore, a first sealing ring is provided at the upper edge of the outer cylinder, and a second sealing ring is provided at the upper edge of the inner cylinder. The height of the outer cylinder is lower than the height of the inner cylinder.

[0008] Furthermore, the upper surface of the outer cylinder is provided with an external thread structure, and the inner wall of the split cylinder cover is provided with an internal thread structure.

[0009] Furthermore, a through hole is provided in the middle of the split cylinder cover, and a fan is installed at the through hole. The fan is fixedly installed on the second sealing ring by bolts.

[0010] Furthermore, the outer surface of the cylinder has a wavy structure, and the recessed part of the wavy structure is used to install the tightening belt.

[0011] Furthermore, a water inlet is provided on the surface of the cylinder, and the water inlet is connected to the interlayer.

[0012] Furthermore, a liquid outlet pipe is provided on the outer surface of the cylinder, with one end extending to the bottom of the inner cylinder and the other end equipped with a liquid outlet pump.

[0013] The advantages of this utility model are:

[0014] 1. An interlayer is provided between the inner and outer cylinders, and water and heating rods are installed in the interlayer to ensure that the coating in the inner cylinder is heated evenly and maintains a stable temperature during its high-speed dispersion process.

[0015] 2. Because different water-based metallic coatings require different dispersing disc rotation speeds, some dispersion speeds that are too high will produce foam, while others that are too slow will result in uneven dispersion. Therefore, multiple accelerating gears are set up in conjunction with the central gear to allow for selective application.

[0016] 3. A detachable cylinder cover is installed at the upper end of the cylinder body. The detachable cylinder cover is sealed to the cylinder body. At the same time, a fan is installed in the middle of the detachable cylinder cover. When the fan is started, it can discharge the air inside the cylinder to the outside, reduce the air pressure inside the cylinder, and reduce the bubbles generated by the coating during the dispersion process.

[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] A high-speed disperser for water-based metallic coatings includes a cylinder and a dispersion disc. The dispersion disc is disposed within the cylinder, which has an opening at the top and a detachable cover. The cylinder comprises an inner cylinder and an outer cylinder, with a sandwich structure between them. The sandwich structure is filled with water and contains a heating rod. An acceleration gearbox is located at the bottom of the cylinder, containing a central gear and several acceleration gears. A main shaft is mounted on the central gear and connected to the dispersion disc, driving its rotation. The acceleration gears are coplanar with the central gear and arranged around it, with each gear having a different number of teeth. A first sealing ring is located at the upper edge of the outer cylinder, and a second sealing ring is located at the upper edge of the inner cylinder. The outer cylinder is shorter than the inner cylinder. The upper surface of the outer cylinder has an external thread structure, and the inner wall of the detachable cover has an internal thread structure. A through hole is located in the center of the detachable cover, through which a fan is installed. The fan is bolted to the second sealing ring. The outer surface of the cylinder has a corrugated structure, with recesses for installing a tensioning belt. A water inlet is provided on the surface of the cylinder, and the water inlet is connected to the interlayer. A liquid outlet pipe is located on the outer surface of the cylinder, with one end of the liquid outlet pipe extending to the bottom of the inner cylinder and the other end of the liquid outlet pipe equipped with a liquid outlet pump.

[0024] The actual usage method is as follows:

[0025] First, water is injected into the jacket through the water inlet until the water level exceeds the highest point of the heating rod. The water temperature is controlled at 40 to 45 degrees Celsius using the heating rod. When used for dispersing other coatings, the water temperature can be adjusted to other suitable temperatures. Then, the water-based metallic coating is injected into the inner cylinder.

[0026] Under normal circumstances, the detachable cylinder cover is installed with the cylinder body. The installation method can be threaded connection. The main function of the detachable cylinder cover is to seal the inside of the inner cylinder and the outer cylinder. Due to the second sealing ring in the inner cylinder and the first sealing ring on the upper edge of the outer cylinder, the two sealing rings are pressed together by the detachable cylinder cover to achieve the sealing of the inner cylinder and the outer cylinder. This seal cannot achieve a complete seal, but only reduces the amount of air flowing in the inner cylinder.

[0027] The split-type cylinder cover has a through hole in the middle, and a fan is installed at the through hole. When the fan is turned on, the air in the inner cylinder can be discharged, reducing the air content in the cylinder and preventing bubbles from forming when the coating is dispersed in the cylinder.

[0028] The outer cylinder has a corrugated structure on its outer wall. During use, one end of a tightening strap is wrapped around the surface of the outer cylinder, and the other end is wrapped around the drive unit. The bottom of the drive unit is connected to a drive gear, which meshes with an acceleration gear at the bottom of the disperser to achieve drive. The bottom of the cylinder is equipped with an acceleration gear box containing multiple acceleration gears. The drive gear of the drive unit meshes with different acceleration gears, providing different rotation speeds for the dispersing disc of the disperser.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
