[0002] In the field of environmentally friendly coatings, coating processing technology plays a crucial role in product quality and is one of the core factors that determine a product's market success. The grinding of the coating slurry is crucial throughout the entire process, and its effectiveness directly impacts the quality of the finished coating. Traditional grinding equipment often utilizes a relatively simple design, which makes it difficult for the coating slurry to enter the grinding area. Due to the lack of a reasonable and efficient guidance mechanism, the slurry cannot fully enter the grinding area at a sufficient flow rate and appropriate flow rate. Summary of the Invention

[0005] S1: Add water, dispersant and wetting agent into a stirring tank and stir evenly;

[0006] S2: Then add pigment and filler, start the stirring kettle and stir to make the pigment and filler initially wet and disperse in the water to form a uniform slurry;

[0007] S3: The slurry is placed in the container barrel for grinding, and the slurry coming out of the container barrel is subjected to secondary grinding;

[0008] S4: Return the ground slurry to the stirring kettle, add water-based acrylic emulsion, film-forming aid, thickener, and defoamer, and stir and mix.

[0025] like Figure 5-8 As shown;

[0026] Since the environmentally friendly paint processing device includes a container tube 101, a tapered tube 102 is integrally formed at the lower part of the container tube 101, a tapered block 301 is arranged in the tapered tube 102, and a plurality of grooves 302 are provided in an annular shape on the upper part of the tapered block 301. The inner side of the tapered tube 102 is a rough surface, and the outer side of the tapered block 301 is a rough surface. When the paint slurry is poured into the container tube 101, the paint slurry will flow along the plurality of grooves 302 into between the tapered block 301 and the tapered tube 102, and at this time, the tapered block 301 is driven to rotate about its own axis;

[0027] As the conical block 301 rotates, the paint slurry between its outer rough surface and the inner rough surface of the conical barrel 102 is subjected to strong shearing, squeezing, and grinding. This combined force effectively disperses particle agglomerates in the paint, refines particle size, and promotes uniform mixing of different components.

[0028] As conical block 301 rotates, the solid particles in the paint slurry constantly rub and collide with the two rough surfaces, further breaking them up and evenly dispersing them. This mechanical action not only improves the paint's fineness and uniformity, but also strengthens the bonding between the various components, improving the paint's stability and performance. Furthermore, the design of grooves 302 not only guides the paint slurry into the processing area but also generates localized turbulence during rotation, which helps enhance mixing.

[0029] During processing, the shear force can be controlled by adjusting the rotational speed of the conical block 301 to accommodate different coating formulations and processing requirements. Higher rotational speeds produce stronger shear forces, making them suitable for processing high-viscosity coatings or those requiring finer particle dispersions; lower rotational speeds are suitable for processing low-viscosity coatings or shear-sensitive ingredients. This flexible adjustment allows the device to meet diverse environmentally friendly coating production requirements.

[0030] In addition, due to the structural design of the integrally formed conical tube 102 and the container tube 101, the risk of paint residue and leakage during the transportation process is reduced, which meets the requirements of environmentally friendly production.

[0031] like Figure 7-8 As shown;

[0032] Since the main shaft 303 is fixed to the upper part of the conical block 301, the upper part of the main shaft 303 is connected to the output shaft of the motor 306 through a coupling, and the motor 306 is fixed to the motor frame 305;

[0033] Motor 306, the power source, transmits power to spindle 303 via a coupling, thereby driving the stable rotation of conical block 301. This connection ensures efficient power transmission while also mitigating vibrations during operation, ensuring the stability and reliability of the device. The design of motor frame 305 not only provides firm support for motor 306 but also effectively isolates vibrations generated during operation, preventing them from being transmitted to other components and impacting machining results.

[0034] During operation, the axis of the main shaft 303 is strictly aligned with the central axis of the conical barrel 102, ensuring that the conical block 301 maintains a uniform gap with the inner wall of the conical barrel 102 during rotation. This precise coaxial design is crucial for ensuring that the coating slurry is subjected to uniform shearing and grinding action throughout the entire circumference, avoiding the problem of over- or under-treatment in local areas, thereby ensuring stable product quality.

[0035] To meet diverse production needs, motor 306 utilizes a variable frequency drive. By adjusting the motor's speed, the rotational speed of conical block 301 can be precisely controlled, thereby adjusting the shear force applied to the coating slurry. This flexibility enables the device to accommodate a wide range of product types, from low-viscosity water-based coatings to high-viscosity oil-based coatings, enhancing its versatility and applicability.

[0036] like Figure 5-8 As shown;

[0037] Since the motor frame 305 is vertically slidably connected to the gantry 307, protruding pieces 308 are fixed on the front and rear sides of the container tube 101. The gantry 307 is vertically slidably connected to the two protruding pieces 308. The gantry 307 is driven up and down by a hydraulic cylinder, and the main shaft 303 is inserted into the gantry 307 with a clearance fit.

[0038] The hydraulic cylinder drives the gantry 307 to slide vertically along the protrusion 308. By adjusting the height of the gantry 307, the axial position of the conical block 301 in the conical cylinder 102 can be accurately controlled, thereby adjusting the size of the annular gap between the conical block 301 and the conical cylinder 102.

[0039] The clearance fit between the spindle 303 and the gantry 307 ensures free rotation of the spindle 303 while providing smooth vertical guidance. As the gantry 307 rises or falls, the spindle 303 moves synchronously without affecting its rotational stability. This structural design allows the position of the tapered block 301 to be adjusted in real time during operation based on the coating's characteristics and processing requirements, dynamically optimizing processing parameters.

[0040] like Figure 7-8 As shown;

[0041] Two retaining rings 304 are fixed to the main shaft 303, located on the upper and lower sides of the gantry 307. A compression spring is sleeved on the main shaft 303 and arranged on the lower side of the gantry 307. The lower end of the compression spring presses against the retaining ring 304 located on the lower side. The two retaining rings 304 limit the vertical displacement of the main shaft 303. The compression spring applies a downward force to the retaining ring 304 located on the lower side, exerting a downward force on the main shaft 303 and the conical block 301, allowing the conical block 301 to press down on the paint slurry on the inner wall of the conical cylinder 102. The compression spring applies continuous elastic pressure to the lower retaining ring 304, ensuring that the conical block 301 maintains a stable downward pressure on the paint slurry. This design not only ensures that the paint is subjected to uniform pressure in the conical gap, but also automatically adjusts the pressure distribution according to the material characteristics and processing stage. The gantry 307 slides vertically on two tabs 308, controlling the degree of compression of the compression spring and, consequently, the grinding pressure. When the coating slurry has a high viscosity or large particle size, the spring is further compressed, increasing the pressure of the conical block 301 on the slurry, thereby enhancing the shearing and grinding effects. Conversely, when processing low-viscosity materials, the spring pressure is reduced accordingly, preventing over-processing that could degrade coating performance.

[0042] like Figure 5-6 As shown;

[0043] Since side ears 106 are fixed on the left and right sides of the upper part of the container tube 101, a vertical rod 105 is fixed on the lower side of each side ear 106, and a disc 104 is fixed on the lower end of each vertical rod 105, the container tube 101 is vertically slidably connected to the ring 201, and support legs 206 are fixed on the left and right ends of the ring 201. The two vertical rods 105 are respectively vertically slidably connected to the two support legs 206, and each vertical rod 105 is sleeved with a compression spring, which is located between the corresponding disc 104 and the support leg 206. The container tube 101 can slide vertically on the ring 201, and the two vertical rods 105 can slide vertically on the two support legs 206 respectively. The compression springs on the two vertical rods 105 give downward pressure to the two discs 104 and the two vertical rods 105, so that the container tube 101 always has a tendency to move downward, and the two support legs 206 and the ring 201 can support the container tube 101 in the air.

[0044] like Figure 5-6 As shown;

[0045] Since the bottom bars 203 are welded to the lower ends of the legs 206 , the bottom bars 203 allow the two legs 206 to be stably placed on the ground, thereby supporting the container tube 101 in suspension above the ground.

[0046] like Figure 5-6 and 9-10;

[0047] Since the lower end of the conical cylinder 102 is connected to the discharge head 103 through a thread, the lower side of the discharge head 103 is evenly distributed with a plurality of leakage holes 107, the lower side of the discharge head 103 is a rough surface, the discharge head 103 is pressed on the grinding disc 401, the edge of the grinding disc 401 is provided with an annular edge, the outer periphery of the grinding disc 401 is fixed with a conical filter plate 404, the outer periphery of the conical filter plate 404 is fixed with a retaining edge 403, and the paint slurry after being ground by the conical cylinder 102 and the conical block 301 will be discharged from the discharge head 10 3 flows out through the multiple leak holes 107 on the conical cylinder 102, and then the paint slurry flows onto the grinding disc 401, causing the grinding disc 401 to move horizontally relative to the discharge head 103, and then the paint slurry is secondary ground by the discharge head 103 and the grinding disc 401. The container tube 101 always has a tendency to move downward, so that there is pressure between the discharge head 103 and the grinding disc 401, which improves the grinding effect. The discharge head 103 and the grinding disc 401 perform secondary grinding on the paint slurry, further improving the fineness of the paint. The threaded connection design between the discharge head 103 and the conical cylinder 102 is not only convenient for disassembly and cleaning. The uniform distribution design of the leak holes 107 ensures that the paint slurry flowing out of the conical area can be evenly distributed on the grinding disc 401, avoiding local accumulation and uneven grinding. The rough surface on the underside of the discharge head 103 cooperates with the grinding disc 401 to form the first grinding interface. When the grinding disc 401 moves horizontally, the micro-protrusions on the rough surface scrape and squeeze the paint particles, further breaking up larger particle agglomerates. The annular edge of the grinding disc 401 prevents the slurry from overflowing, ensuring that the paint stays within the grinding area. After grinding, the paint slurry passes through multiple flow channels 402 to the periphery of the grinding disc 401, and the conical filter plate 404 begins to work. Its inclined surface and fine filter pore structure can effectively separate particles that do not meet the particle size requirements. Qualified paint flows out through the filter pores on the conical filter plate 404. The setting of the retaining edge 403 prevents the paint from overflowing from the outside of the conical filter plate 404.

[0048] like Figure 5-6 and 9-10;

[0049] Since side rods 202 are fixed on both sides of the annular edge of the grinding disc 401, each leg 206 is provided with a slide 205, each slide 205 is slidably connected to a slide 204, and the slide 204 is driven to slide by a hydraulic cylinder, the two side rods 202 are respectively connected to the two slides 204 in a transverse sliding manner, and the side rods 202 are driven to slide on the slide 204 by the hydraulic cylinder;

[0050] The multi-dimensional motion control of the grinding disc 401 is achieved through the coordinated operation of two sets of hydraulic cylinders, forming a precise planar motion system. The left and right side rods 202 are connected to the lateral sliding of the slide 204. Combined with the forward and backward sliding of the slide 204 within the chute 205 of the support leg 206, the grinding disc 401 can achieve forward and backward, left and right movement within the horizontal plane. This allows the grinding disc 401 to move forward and backward, left and right relative to the discharge head 103, thereby achieving secondary grinding of the paint slurry. The forward and backward, left and right movement of the grinding disc 401 and the conical filter plate 404 can also be used to remove the paint slurry remaining on the conical filter plate 404, thereby improving the filtration efficiency of the conical filter plate 404 on the paint slurry and making the paint more delicate.
