Description

Technical Field

[0001] This utility model relates to the field of paint impurity separation technology, and in particular to a paint impurity separation device. Background Technology

[0002] Paint is a liquid or paste-like substance used to cover the surface of objects, primarily for decoration, protection, or to impart specific functions (such as corrosion resistance, waterproofing, and high-temperature resistance). Paints typically consist of pigments, resins, solvents, and additives. During production and use, paints may contain impurities, such as undissolved solid particles, airborne dust, or other contaminants. These impurities can affect the uniformity, appearance, and performance of the paint, and may even lead to uneven coating, peeling, or blistering. Therefore, impurity separation is essential to ensure paint quality, improve coating stability and durability, and ultimately achieve better protective and decorative effects.

[0003] However, existing paint impurity separation devices mostly rely on a single continuous rotation for filter cartridge drive, which fails to maximize the paint ejection and impurity separation effects, resulting in large particles not being completely removed. Furthermore, filter cartridge cleaning often depends on nozzle rinsing. While this removes some residual paint, the limited cleaning methods of the nozzles make it difficult to thoroughly clean the outside of the filter cartridge, easily leading to stubborn paint buildup and affecting the separation effect in subsequent uses and the long-term stability of the equipment.

[0004] To address the above problems, a coating impurity separation device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a coating impurity separation device, which aims to solve the problems of insufficient separation efficiency and incomplete cleaning of the filter cartridge in an existing coating impurity separation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coating impurity separation device, comprising a separation cylinder, a top cover installed on the top of the separation cylinder, a feed inlet provided in the middle of the top cover, a driving assembly provided at the bottom of the separation cylinder, a turntable rotatably connected to the inner bottom wall of the separation cylinder, a separation filter cylinder fixedly connected to the top of the turntable, and multiple snap-fit ​​assemblies provided inside the top cover;

[0007] The drive assembly includes a drive motor, a drive gear, a driven gear, and a transmission gear. The drive motor is fixedly connected to the bottom of the separator cylinder. The output end of the drive motor is fixedly connected to the bottom center of the drive gear. The drive gear and the driven gear mesh with each other, and both of them have multiple teeth fixedly connected to their tops. A rotating rod is fixedly connected to the bottom of the driven gear, and a connecting rod is fixedly connected to the top center of the transmission gear.

[0008] As a further description of the above technical solution:

[0009] The transmission gear meshes with the plurality of teeth, and the transmission gear and the driving gear are not at the same height.

[0010] As a further description of the above technical solution:

[0011] The number of teeth on the top of the driven gear and the driving gear is the same, and is half the number of teeth on the transmission gear.

[0012] As a further description of the above technical solution:

[0013] The rotating rod is rotatably connected inside the separating cylinder, and the top of the connecting rod is fixedly connected to the bottom center of the turntable.

[0014] As a further description of the above technical solution:

[0015] A water inlet is provided on one side of the side wall of the separator, and a discharge port is installed on the other side of the side wall of the separator. A solenoid valve is installed on the top of the discharge port, and multiple feet are provided on the bottom of the separator.

[0016] As a further description of the above technical solution:

[0017] The snap-fit ​​assembly includes a pin, a limiting plate is fixedly connected to the middle of the pin, a spring is sleeved on the outer side of the pin, and a pull rope is fixedly connected to the end of the pin.

[0018] As a further description of the above technical solution:

[0019] The top cover has three sliding grooves inside, and the limiting plate is slidably connected inside the sliding grooves.

[0020] As a further description of the above technical solution:

[0021] The top cover has three cleaning brush rollers inserted inside, and the end of the pin is inserted into the top of the cleaning brush roller.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model employs a gear meshing drive method. Driven by a motor, the gears mesh with each other, driving the filter cartridge to reciprocate. The clockwise and counterclockwise half-turn rotations alternate, which effectively achieves the coating material ejection during rotation and improves the efficiency of impurity separation. The reciprocating rotation mechanism not only ensures efficient coating removal but also prevents impurity accumulation, improving the stability and reliability of the entire filtration system.

[0024] 2. In this utility model, in addition to the traditional nozzle cleaning method, a brush device is installed on the outside of the filter cartridge for cleaning. The brush surrounds the outside of the filter cartridge, enabling comprehensive and thorough cleaning. This design ensures that stubborn paint or impurities do not easily accumulate on the surface of the filter cartridge. At the same time, the brush can effectively remove paint residue adhering to the outside of the filter cartridge during rotation, ensuring that the filter cartridge remains clean after each use and providing a more efficient working environment for the next paint treatment.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 6 This utility model provides an embodiment of a paint impurity separation device, comprising a separation cylinder 1, a top cover 11 mounted on the top of the separation cylinder 1, and a feed inlet 12 located in the middle of the top cover 11 for introducing the paint to be processed into the separation cylinder 1. To improve the efficiency of the equipment, a water inlet 13 is provided on one side of the separation cylinder 1, which can introduce water flow for auxiliary cleaning or dilution of the paint to enhance the separation effect; it also facilitates subsequent water injection into the separation cylinder 1 for cleaning. A discharge outlet 14 is mounted on the other side of the separation cylinder 1, and a solenoid valve 2 is mounted on the top of the discharge outlet 14. The opening and closing of the discharge outlet 14 is controlled by adjusting the solenoid valve 2 to ensure that the discharge process is controllable and precise. To support the entire separation cylinder 1, multiple feet 15 are provided at the bottom of the separation cylinder 1, which serve to stabilize the equipment. A drive assembly 5 is provided at the bottom of the separation cylinder 1, which is connected to a turntable 4 to provide the necessary power. A turntable 4 is rotatably connected to the inner bottom wall of the separating cylinder 1, and a separating filter cylinder 3 is fixedly connected to the top of the turntable 4. The turntable 4 rotates under the action of the drive assembly 5 to ensure that the paint and the separating filter cylinder 3 are in full contact, promoting the separation of impurities. The separating filter cylinder 3 is mainly used to filter impurities in the paint, and its fine pore size can effectively remove large particles in the paint. The top cover 11 has multiple snap-fit ​​assemblies 7 inside, which can be connected to the cleaning brush roller 6 to clean the separating filter cylinder 3 after separation.

[0035] Reference Figure 2 - Figure 4The drive assembly 5 includes a drive motor 501, a drive gear 502, a driven gear 503, and a transmission gear 504. The drive motor 501 is fixedly connected to the bottom of the separator 1, providing power to the entire drive system. The output end of the drive motor 501 is fixedly connected to the bottom center of the drive gear 502, transmitting power through the drive gear 502. The drive gear 502 and the driven gear 503 transmit power through meshing, and both have multiple teeth 506 fixedly connected to their tops. The number of teeth 506 on the tops of the driven gear 503 and the drive gear 502 is the same, and their number is half the number of teeth on the transmission gear 504. This design ensures the accuracy of the gear system's transmission ratio, guaranteeing the reciprocating rotation effect of the separator 3. The transmission gear 504 meshes with the multiple teeth 506, enabling the drive gear 502 and the driven gear 503 to drive the transmission gear 504, rotating it half a turn clockwise and half a turn counterclockwise, and repeating this process. A rotating rod 507 is fixedly connected to the bottom of the driven gear 503. The rotating rod 507 is rotatably connected inside the separating cylinder 1, which can stabilize the driven gear 503. A connecting rod 505 is fixedly connected to the top center of the transmission gear 504. The top of the connecting rod 505 is fixedly connected to the bottom center of the turntable 4, ensuring that the turntable 4 reciprocates and rotates in both directions under the drive of the transmission system, thereby completing the efficient separation of paint impurities.

[0036] Reference Figure 5 - Figure 6 The snap-fit ​​assembly 7 includes a pin 701 for connecting the top cover 11 and the cleaning brush rollers 6. After the paint is separated, three cleaning brush rollers 6 are inserted inside the top cover 11, surrounding the inner side of the separation filter cartridge 3 to effectively clean the surface of the filter cartridge. The end of the pin 701 is inserted into the inside of the top tip of the cleaning brush roller 6, ensuring the cleaning brush roller 6 is stable within the top cover 11. A limiting plate 702 is fixedly connected to the middle of the pin 701, controlling the range of motion of the pin 701. Three sliding grooves 704 are provided inside the top cover 11, allowing the limiting plate 702 to slide freely inside, thereby enabling the installation and removal of the cleaning brush rollers 6. A spring 703 is sleeved on the outside of the pin 701, providing appropriate pressure to ensure that the pin 701 can quickly return to its original position during movement, maintaining the normal operation of the device. Finally, a pull rope 705 is fixedly connected to the end of the pin 701 for manual operation of the pin 701, which makes it easy for users to disassemble or replace the cleaning brush roller 6 when needed, thus improving the ease of equipment maintenance.

[0037] Working Principle: The paint to be treated is discharged into the separator cylinder 1 through the feed inlet 12. Inside the separator cylinder 1, the paint initially contacts the separator filter cylinder 3. Then, the drive motor 501 in the drive assembly 5 drives the driven gear 503 to rotate via the drive gear 502. The same number of teeth 506, distributed on different sides of their tops, mesh with the transmission gear 504, allowing it to rotate half a turn counterclockwise and then half a turn clockwise. The connecting rod 505 at the top of the transmission gear 504 drives the turntable 4 to rotate, thereby causing the separator filter cylinder 3 to reciprocate. As the separator filter cylinder 3 rotates, impurities are separated from the paint. Larger particles are trapped by the separator filter cylinder 3, while the clean paint continues to flow and is discharged through the discharge port 14. The solenoid valve 2 controls the opening and closing of the discharge port 14 to ensure the discharge process is controllable. After impurity separation is complete, the equipment enters the cleaning stage. The cleaning process is achieved through three cleaning brush rollers 6 inside the top cover 11. These cleaning brush rollers 6 surround the inner side of the separator filter cartridge 3. Clean water is injected into the separator cartridge 1, and the drive assembly 5 is activated to scrub the surface of the filter cartridge. The cleaning brush rollers 6 are connected to the top cover 11 via pins 701. Pins 701 cooperate with a limiting plate 702, and the cleaning brush rollers 6 are installed and removed via a sliding groove 704. Pins 701 are manually operated via a pull rope 705, allowing users to easily remove the cleaning brush rollers 6.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
