[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. 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.

[0023] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 and Figure 2 As shown, a multi-stage filtration device for solvent-based road marking paint includes a base 1, a filtration structure 2 above the base 1, and separation tanks 21 including, but not limited to, a first separation tank 23, a second separation tank 24, and a third separation tank 25. Corresponding through holes are provided between the separation tanks 21 and the storage tank 11, and screens 26 are provided within the through holes. The filtration structure 2 includes several separation tanks 21 placed above the base 1 and interconnected. Each separation tank 21 has a centrifuge disc 22 corresponding to itself inside, and a storage tank 11 corresponding to the centrifuge disc 22 is provided on one side of each separation tank 21.

[0026] In this embodiment, the present invention utilizes a multi-stage screening system 2 configured on top of the base 1, employing a series of interconnected separation tanks 21 to achieve graded screening of the coating. Through the action of the centrifugal disc 22, the coating is thrown against the sidewall of the separation tank 21 under centrifugal force. Coating meeting specific particle size requirements then enters the collection tank 11. Coating not meeting the particle size requirements continues to rotate along the sidewall and is eventually sent to the next separation tank 21. During this process, the separation tank 21 also functions as a cleaner for the screens and sidewalls, ensuring efficient system operation.

[0027] like Figure 3 and Figure 4As shown, the mesh size of the screen 26 increases sequentially in the order of the first separation tank 23, the second separation tank 24, and the third separation tank 25 to achieve the separation of coatings of different particle sizes. Each separation tank 21 has a corresponding cap, and a feeding port 12 is located near the first separation tank 23 to feed unfiltered coatings into the filter structure 2. The separation tanks 21 are interconnected by a through-tube 13. The direction of the through-tube 13 is designed to follow the arc direction of the fan blades of the centrifugal disc 22 within the corresponding separation tank 21, so that the coatings can smoothly transition from one separation tank 21 to the next under centrifugal force. The centrifugal disc 22 has a through-tube drive shaft 14, and a meshing gear 15 is located at the end of the drive shaft 14 away from the cap. This design allows the centrifugal disc 22 to rotate under the drive of the gear 15, generating centrifugal force and promoting the separation process of the coatings. A drive motor 16 located inside the base 1 is connected below any of the gears 15. The drive motor 16 provides power for the rotation of the centrifugal disc 22, ensuring the continuity and efficiency of the coating separation process.

[0028] In this embodiment, this structural design enables continuous separation of solvent-based road marking paint in multi-stage separation tanks 21. Each stage of the separation tank 21 effectively filters paint of a specific particle size, while paint that does not meet the particle size requirements is transferred to the next separation tank 21 for further screening. This continuous, multi-stage screening process significantly improves the filtration efficiency and separation accuracy of the paint, ensuring the quality of the final product. Furthermore, the inclusion of the drive motor 16 allows for automated control of the entire filtration process, reducing the tediousness of manual operation and improving production efficiency.

[0029] When using:

[0030] 1. Preparations:

[0031] Ensure all equipment components are intact and undamaged.

[0032] Check the power connection to ensure that drive motor 16 and other electrical components are functioning properly.

[0033] 2. Installation and Configuration

[0034] 3. Feeding:

[0035] Open the feeding port 12 on the first separation tank 23 and put the unfiltered solvent-based road marking paint into it.

[0036] 4. Start the drive motor:

[0037] Start the drive motor 16 inside the base 1. The drive motor 16 drives the centrifugal disc 22 to rotate through the gear 15 and the drive shaft 14.

[0038] 5. Filtration and separation:

[0039] The coating is thrown against the side wall of the separation tank 21 under the action of centrifugal force and is screened through the screen 26.

[0040] Coatings conforming to a specific particle size class pass through screen 26 into storage tank 11, while larger particles continue to rotate within separation tank 21.

[0041] 6. Multi-level filtering:

[0042] The coating that does not meet the particle size requirements continues to rotate along the sidewall and is eventually sent through the channel pipe 13 to the next separation tank 21 for further screening.

[0043] 7. Collection and Cleaning:

[0044] Collect the filter coating from each storage tank 11, ready for the next step of use or packaging.

[0045] After production is completed, the screen 26 and side walls inside the separator 21 are cleaned to maintain the efficient operation of the system.

[0046] 8. Turn off the equipment:

[0047] After completing all filtration work, turn off drive motor 16 and disconnect the power supply.

[0048] 9. Maintenance and Inspection:

[0049] Regularly maintain and inspect the equipment to ensure that all components are working properly, especially the drive motor 16 and the electrical system.

[0050] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
