Description
Technical Field
[0001] This utility model relates to the field of paint processing technology, and specifically to a filter device for camouflaging paint. Background Technology
[0002] Paint is a chemical mixture that adheres firmly to the surface of an object, serving protective, decorative, marking, and other special purposes. A paint is a material that can be applied to the surface of an object using different application techniques to form a firmly adhering, continuous solid film with a certain strength. This film is commonly called a coating film, also known as a paint film or coating layer. Paint generally consists of four parts: film-forming substances, fillers (pigments and fillers), solvents, and additives. The composition may vary slightly depending on performance requirements; for example, varnishes may not contain pigments and fillers, and powder coatings may not contain solvents. It belongs to organic chemical polymer materials, and the resulting coating film is a type of polymer compound. According to the modern classification of chemical products, paint belongs to fine chemical products. Modern paints are gradually becoming a multifunctional engineering material and an important sector within the chemical industry.
[0003] Paint is a viscous, oily pigment that is flammable when undried. It is insoluble in water, slightly soluble in fats, and soluble in alcohols, aldehydes, ethers, benzene, and alkanes. It is readily soluble in gasoline, kerosene, and diesel fuel. During the paint production process, impurities inevitably enter the paint, affecting its performance; therefore, filtration is essential before use.
[0004] Paint has a certain degree of viscosity, and relying solely on gravity for filtration generally results in low filtration efficiency, and the filter residue is not easy to clean. Summary of the Invention

[0006] box rack;
[0007] The bottom of the frame is fixedly connected to a filter plate for filtering paint liquid, which is two opposing arc-shaped plate structures;
[0008] The frame is fixedly equipped with a feeder for guiding the paint liquid into and axially and evenly falling onto the filter plate;
[0009] The frame has two rotating shafts that rotate relative to each other. Connecting rods are fixedly mounted at both ends of the rotating shafts. The connecting rods at both ends correspond one-to-one, and scrapers are installed between the corresponding connecting rods.
[0010] A rotation drive component, which is connected to the rotation shaft for driving two rotation shafts to rotate synchronously relative to each other;

Detailed Implementation
[0028] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims. Example
[0029] refer to Figures 1-4 This embodiment proposes a camouflage paint filtration device for filtering liquid paint and removing solid particles. The camouflage paint filtration device may include:
[0030] A frame 14 forms a supporting foundation. The frame 14 can be a rectangular frame structure with support plates connected to both ends. The frame 14 can be made of stainless steel, providing rigidity and ensuring the stability of the filtration device. A filter plate 5 is fixedly connected to the bottom of the frame 14. The filter plate 5 is used to filter paint liquid. The filter plate 5 can be two opposing arc-shaped plate structures, where the paint liquid falls onto the filter plate 5 to complete the filtration. During installation, the filter plate 5 is fixed to the rectangular frame, with support plates positioned on both sides of the filter plate 5.
[0031] A feed component 1 is fixedly installed on the frame 14. The feed component 1 guides the paint liquid into the filter plate 5 and axially and evenly falls onto the filter plate 5. The feed component 1 can be a trough-shaped structure. When filtration is required, the paint liquid can be poured into the interior of the feed component 1 and guided by the feed component 1 onto the filter plate 5. Since the filter plate 5 consists of two opposing arc-shaped plate structures, the curvature of the arc-shaped plate structures is generally between 70 and 100 degrees, although other values are not excluded. The paint liquid guided by the feed component 1 falls on the center line of the filter plate 5. The feed component 1 can also be a guide pipe for spraying paint liquid. The guide pipe can be a circular pipe structure with an opening at the bottom, which can be connected to the raw material pipe pumped in. Specific details are not elaborated here.
[0032] The frame 14 has two rotating shafts 11 rotatably mounted opposite each other. Connecting rods 12 are fixedly mounted at both ends of each shaft 11, with each connecting rod 12 corresponding to the other. Scrapers 13 are positioned between the corresponding connecting rods 12. The scrapers 13 spread the paint liquid on the filter plate 5 by rotating, thereby increasing the spreading area of the paint liquid and improving the utilization area of the filter plate 5. Under the action of gravity, the paint liquid on the filter plate 5 flows downwards, causing it to flow back and forth, improving filtration efficiency. Under the agitation of the scrapers 13, the paint liquid is pushed upwards on the filter plate 5, passing through it, while solid particles are pushed out by the scrapers 13 from the upper edge of the filter plate 5, thus completing solid-liquid separation. To ensure continuous filtration, the feed rate of the paint liquid and the rotation speed of the scrapers 13 need to be controlled, which can be adjusted based on experience. When paint liquid is being discharged from the top of the filter plate 5, the rotation speed of the scraper 13 can be reduced. When there is no paint liquid being filtered from the top of the filter plate 5, the feed speed of the paint liquid can be increased. Specific values are not elaborated here. Three pairs of connecting rods 12 can be provided, but other quantities are not excluded. The scraper 13 is fixedly connected to the connecting rods 12 at both ends and tilted in the direction of rotation, so that the scraper 13 forms an acute angle with the tangent of the filter plate 5. By tilting the scraper 13, downward pressure can be applied while pushing, thereby increasing the filtration pressure of the paint liquid and improving the filtration efficiency.
[0033] A rotation drive component, connected to the rotation shaft 11, drives two rotation shafts 11 to rotate synchronously relative to each other, thereby allowing the scraper 13 to rotate alternately, reducing the size of the filtration device. The rotation drive component can be driven by two motors. To reduce production costs, the rotation drive component can also include a motor 9, a transmission component 8, and a scraper 13. The motor 9 is mounted on the housing 14 and is connected to one of the rotation shafts 11 via the transmission component 8, which can be a pulley combination. The two rotation shafts 11 are driven by a synchronous meshing gear set 3. This structure reduces manufacturing costs and ensures synchronous relative rotation of the two rotation shafts 11.
[0034] An upper housing 2 can also be fixedly mounted on the frame 14. The upper housing 2 is positioned above the filter plate 5, and the upper housing 2 and the filter plate 5 form a filter cavity. The upper housing 2 helps prevent paint splattering and reduces evaporation. A slag outlet 7 is provided at the connection between the filter plate 5 and the upper housing 2, facilitating the discharge of solid particles pushed out by the scraper 13. A filter slag groove 4 is provided on the frame 14, located outside the slag outlet 7. The filter slag groove 4 facilitates the collection of pushed-out solid particles, thus simplifying cleaning.
[0035] A liquid tank 6 is located below the filter plate 5 and is fixedly connected to the frame 14. Paint liquid passing through the filter plate 5 falls onto the liquid tank 6 for collection. The liquid tank 6 can be sealed to the frame 14 to prevent paint evaporation and air pollution, or it can be open for easy paint cleaning; specific details are omitted here. The liquid tank 6 can be tilted, and a drain pipe 10 can be connected to its bottom. A control valve is installed on the drain pipe 10; opening the control valve allows the paint liquid in the liquid tank 6 to be discharged. The motor 9 can be electrically connected to a controller, which can quantitatively control the transmission speed of the motor 9. The paint liquid inside the feed unit 1 enters the filter plate 5 under gravity and falls to the middle position of the filter plate 5. The motor 9 drives the two rotating shafts 11 to rotate synchronously relative to each other. The scraper 13 rotates with the rotating shafts 11, pushing the paint liquid on the filter plate 5 upward and spreading it out, thereby increasing the effective filtration area of the filter plate 5 and improving the filtration efficiency. The inclined scraper 13 can push the solid particles on the filter plate 5 upward and remove them from the filter plate 5 area to enter the interior of the filter residue tank 4 for collection. The paint liquid falls through the filter plate 5 into the interior of the liquid tank 6 for collection. Example
[0036] refer to Figure 5The scraper 13 is rotatably connected to the ends of the connecting rod 12 at both ends. A torsion spring 15 is provided at the rotatable connection of the scraper 13. The torsion spring 15 causes the scraper 13 to rotate so that its edge contacts the filter plate 5. Under the action of the torsion spring 15, the scraper 13 and the filter plate 5 are always in contact, ensuring tight pushing. A limiting protrusion 16 is fixedly provided on the connecting rod 12. The limiting protrusion 16 is used to limit the rotation angle of the scraper 13, so that the tangent of the rotation direction of the scraper 13 and the filter plate 5 is always at an acute angle, ensuring that the scraper 13 and the filter plate 5 always maintain an acute angle when they are not in contact. When the scraper 13 is scraping material, when the scraper 13 rotates to the slag outlet 7, the scraper 13 contacts the limiting protrusion 16, and the tangent angle between the scraper 13 and the filter plate 5 increases. When the scraper 13 contacts the upper shell 2, the edge of the upper shell 2 can scrape the contact surface of the scraper 13, thereby facilitating the cleaning of the scraper 13.

Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
