[0002] Alkyd paint thinner is mainly composed of alkyd resin and solvent. It is used to dilute alkyd paint, making the paint easier to apply. It is commonly used for coating surfaces such as metal, wood, and plastic, and can enhance the adhesion and gloss of the paint layer.

[0003] Raw material filtration for alkyd paint thinner is a crucial step in the production process, designed to remove impurities and ensure the purity and quality of the thinner. The filtration process effectively removes insoluble solid particles, moisture, precipitates, or other contaminants, which is essential for improving the stability and performance of the final product.

[0004] However, traditional raw material filtration devices rely on a single filtration method, mostly using filter paper, resulting in low filtration efficiency and poor filtration effect. In response, this application proposes a raw material filtration device for alkyd paint thinner. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] Example

[0020] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a raw material filtration device for alkyd paint thinner, including a feeding box 3, a material trough 4 extending through the top and bottom surfaces of the feeding box 3, a first tube 5 connected to the bottom of the feeding box 3, a second tube 6 connected to the bottom of the first tube 5, a discharge pipe 8 connected to the bottom surface of the second tube 6, a molecular sieve 12 inside the first tube 5, and a filter membrane 14 inside the second tube 6. Specifically, the filter membrane 14 can be selected from polytetrafluoroethylene membrane, nylon membrane, polyethersulfone membrane, polypropylene membrane, etc., as required. Filter paper is provided inside the material trough 4.

[0021] In this embodiment, the raw material for alkyd paint thinner is poured into the feed trough 4 of the feed box 3. The raw material is first initially filtered by filter paper to remove larger impurity particles. Subsequently, the raw material after initial filtration enters the first tube 5, where the molecular sieve 12 inside the first tube 5 further performs fine filtration. The molecular sieve 12 has excellent sieving performance and can effectively remove tiny particles, water, or molecular-level impurities from the raw material. The raw material filtered by the molecular sieve 12 continues to flow into the second tube 6, where the filter membrane 14 inside the second tube 6 performs final filtration to ensure the purity and quality of the raw material. The filter membrane 14 can be made of different types of materials according to actual needs to meet different filtration precision and requirements. Finally, the pure raw material after triple filtration is discharged from the discharge pipe 8.

[0022] Furthermore, two vertical supports 2 are symmetrically provided at both ends of the feed box 3, the first tube 5 and the second tube 6, and the bottom of the two vertical supports 2 are connected to the base plate 1.

The feed box 3, the first tube 5 and the second tube 6 are fixed by the base plate 1 and the vertical support 2.

[0024] Furthermore, a placement groove 9 is provided on the top surface of the base plate 1 below the discharge pipe 8.

[0025] In this embodiment, a container is placed in a placement trough 9 to receive the raw material discharged from the feed pipe 8.

[0026] Furthermore, a connecting block 7 is provided between the first tube 5 and the second tube 6. Specifically, the connecting block 7 is fixedly connected to both the first tube 5 and the second tube 6. A through hole 13 is provided between the top and bottom surfaces of the connecting block 7. Specifically, the inner diameter of the through hole 13 is smaller than the diameter of the molecular sieve 12 spheres. The through hole 13 connects the first tube 5 and the second tube 6.

[0027] In this embodiment, the first tube 5 and the second tube 6 are connected through the through hole 13 to isolate the molecular sieve 12.

[0028] Furthermore, the four corners of the material trough 4 are provided with mounting blocks 10, which are fixedly connected to the inner wall of the material trough 4, and the filter paper is fixed to the mounting blocks 10 by screws.

[0029] In this embodiment, the filter paper is fixed by the mounting block 10 and screws.
