Description

Technical Field

[0001] This utility model relates to the field of coating production technology, and more specifically, it relates to a coating material disperser. Background Technology

[0002] Coatings are surface treatment materials widely used in construction, automobiles, furniture and other fields. Their main functions include decoration, protection and special functions (such as fire resistance, corrosion resistance, etc.). They are usually viscous liquids made of resin, oil or emulsion as the main component, with or without pigments and fillers, and with appropriate additives, and are prepared with organic solvents or water. These components need to be mixed by a disperser to form a uniform coating system.

[0003] Traditional dispersers have a relatively simple structure, and the material flows in a relatively simple path under the action of stirring. This results in insufficient convection between materials, which leads to poor dispersion and low stirring efficiency. This not only prolongs the production time but may also cause unstable coating quality and affect the performance of the final product. Utility Model Content

[0022] Reference Figures 1-2 A coating material disperser includes a dispersion vessel 1, a drive sleeve 2 rotatably fitted inside the dispersion vessel 1, a drive mechanism for driving the drive sleeve 2 to rotate on the dispersion vessel 1, an air inlet structure connected to the top of the drive sleeve 2, a support platform 3 fixedly fitted at the bottom of the drive sleeve 2, a cavity 4 opened inside the support platform 3, and a plurality of stirring rods 5 penetrating the cavity 4 fixedly installed at the bottom of the support platform 3, the plurality of stirring rods 5 being arranged in a circular array with the center of the support platform 3 as the center, the plurality of stirring rods 5 being hollow structures that penetrate vertically, and a plurality of air holes 6 opened on the surface of the stirring rods 5.

[0023] Additionally, the air intake structure includes an air pump 7 fixedly mounted on the top of the dispersion vessel 1, an air supply pipe 8 fixedly mounted on the output shaft of the air pump 7, and an air intake pipe 9 rotatably connected to the top of the drive shaft sleeve 2 via a bearing, with the air intake pipe 9 communicating with the air supply pipe 8.

[0024] When the air pump 7 starts, the gas enters the air inlet pipe 9 through the air delivery pipe 8, and then enters the drive shaft sleeve 2. The air inlet pipe 9 and the drive shaft sleeve 2 are connected by a rotating bearing, so that the rotation of the drive shaft sleeve 2 will not affect the gas delivery, thus ensuring the stable delivery of the gas.

[0025] The lower ends of several stirring rods 5 are provided with a base plate 10 that is opposite to the support platform 3. The base plate 10 is fixedly sleeved on the stirring rods 5. The base plate 10 enhances the connection between the lower ends of the multiple stirring rods 5, making the whole system more stable and reliable during the stirring process.

[0026] A stirring shaft 11 is fixedly installed at the middle position of the support platform 3 and the base plate 10. A stirring blade 12 is fixedly installed on the stirring shaft 11. The stirring blade 12 extends in a spiral shape. When the drive shaft sleeve 2 rotates, the stirring shaft 11 also rotates, driving the stirring blade 12 to perform spiral stirring, which can further enhance the dispersion effect on the material. Moreover, the spiral stirring blade 12 can drive the material to move up and down, making the material more evenly dispersed.

[0027] Each of the lower ends of several stirring rods 5 is fixedly provided with a discharge nozzle 13. The output diameter of the discharge nozzle 13 is smaller than the inner diameter of the stirring rod 5. By setting the discharge nozzle 13, most of the gas can be ejected through the air hole 6 and act on the material, while also allowing a small part of the material that enters the stirring rod 5 during the stirring process to have a discharge channel.

[0028] The driving mechanism includes a motor fixedly connected to the dispersion vessel 1. A drive wheel 14 is drivenly connected to the output shaft of the motor. A driven wheel 15 is fixedly sleeved on the drive shaft sleeve 2. A transmission belt 16 is fixedly sleeved between the driven wheel 15 and the drive wheel 14. When the motor starts, it drives the drive wheel 14 to rotate, which in turn drives the driven wheel 15 and the drive shaft sleeve 2 to rotate through the transmission belt 16, thereby realizing the rotation of the stirring rod 5.

[0029] A limiting edge 17 is fixedly sleeved on the outer wall of the stirring rod 5. The limiting edge 17 is located inside the cavity 4 and abuts against the inner bottom wall of the cavity 4. The setting of the limiting edge 17 restricts the downward movement of the stirring rod 5 relative to the support platform 3, ensuring that the stirring rod 5 is more stably installed on the support platform 3 to stir the material.

[0030] A feed pipe 18 is fixedly provided on one side of the dispersion vessel 1 for adding materials into the dispersion vessel 1. A discharge pipe 19 is fixedly provided at the bottom of the dispersion vessel 1. A solenoid valve 20 is fixedly provided on the discharge pipe 19 for controlling the discharge of materials. Support feet 21 are fixedly provided at the four corners of the bottom of the dispersion vessel 1 for supporting and stabilizing the dispersion vessel 1.

[0031] Working principle: When the dispersion vessel 1 is in use, the drive mechanism is activated, which drives the drive shaft sleeve 2 to rotate, thereby driving the support platform 3 and multiple stirring rods 5 on the support platform 3 to rotate synchronously. The stirring rods 5 are arranged in a circular array with the center of the support platform 3 as the center, which can stir and disperse the material in the dispersion vessel 1 in all directions. The air inlet structure delivers gas into the drive shaft sleeve 2. The gas is dispersed into the interior of each stirring rod 5 through the cavity 4 in the support platform 3, and is ejected through the air holes 6 on the surface of the stirring rod 5. This allows the airflow to continuously impact the material while the stirring rods 5 are stirring the material, enhancing the convection and mixing between the materials.

[0032] This invention achieves all-round mixing and dispersion of materials through the rotation of the support platform 3 and the stirring rod 5, ensuring mixing efficiency. At the same time, the air intake structure delivers gas into the stirring rod 5 and sprays it out through the air hole 6, so that the airflow and the stirring action are combined to further enhance the mixing effect of the materials and improve the dispersion efficiency.

[0033] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
