Description

Technical Field

[0001] This utility model relates to the technical field of anti-corrosion coating preparation equipment, specifically a centrifugal dispersion device for preparing anti-corrosion coatings. Background Technology

[0002] Anti-corrosion coatings, also known as anti-corrosion coatings, refer to a class of liquid or solid materials that, when applied to the surface of an object, can form a thin film under certain conditions to provide protection, decoration, or other special functions (insulation, rust prevention, mildew prevention, heat resistance, etc.). In the production process of anti-corrosion coatings, the materials used in the production of anti-corrosion coatings need to be centrifuged and dispersed.

[0003] A search revealed that patent publication number CN213668827U discloses a centrifugal dispersion device for paint production, including a stirring centrifugal dispersion mechanism and a material barrel fixing mechanism. The material barrel fixing mechanism is fixedly installed on the stirring centrifugal dispersion mechanism. When the material barrel height is insufficient and the stirring blade cannot extend into the material barrel, the collar block is moved downward on the support guide column, and then the first locking screw is tightened for fixation, allowing the stirring blade to extend into the material barrel for dispersion and stirring. This facilitates the dispersion and stirring of solvents in material barrels of different heights. A horizontal insertion hole is opened in the middle of the support column block, and the mounting column is movably installed on the support column block through the insertion hole. When fixing the material barrel, the mounting column is moved according to the diameter of the material barrel to adjust the distance between the two reinforcing clamps, which facilitates the fixing of material barrels of different diameters. Rubber pads are fixedly provided at both ends of the side of the reinforcing clamps, which increases the friction and improves the clamping effect when clamping and fixing the material barrel.

[0004] In existing centrifugal dispersion devices for the preparation of anti-corrosion coatings, when workers add powder to the material cylinder during actual dispersion operations, some powder escapes. This escaped powder flows into the working environment, polluting the work environment and affecting the health of workers. Therefore, a centrifugal dispersion device for the preparation of anti-corrosion coatings is designed. Utility Model Content

[0045] The vacuuming mechanism 700 is equipped with a housing 710. Inside the housing 710, a plate filter 750 and a third rotating shaft 740 are arranged on the upper part. The plate filter 750 is located above the third rotating shaft 740. Both ends of the plate filter 750 are installed in the U-shaped grooves on the U-shaped clamping plate 730.

Because the circumferential outer wall of the limiting post 770 is clearance-fitted with the hole wall of the through hole, it can limit and guide the direction of vibration of the plate filter 750.

[0046] Both ends of the limiting post 770 pass through the through holes on the surface of the connecting plate 713 and are connected to the limiting plate 790.

[0047] A second rotating shaft 720 is installed in the through hole at the center of the surface of the plate filter screen 750. A first bevel gear 723 is installed at the bottom of the second rotating shaft 720. The first bevel gear 723 meshes with the second bevel gear 742, and the second bevel gear 742 is located on the outer wall of the third rotating shaft 740. The two ends of the third rotating shaft 740 are respectively installed in bearings on the outer walls of the two sides of the housing 710. Cams 741 are provided on both sides of the circumferential outer wall of the third rotating shaft 740, and the outer wall of the cams 741 contacts the bottom of the U-shaped clamping plate 730. When the second rotating shaft 720 rotates, it drives the first bevel gear 723 to rotate. When the first bevel gear 723 rotates, it drives the second bevel gear 742 to rotate. When the second bevel gear 742 rotates, it drives the third rotating shaft 740 to rotate. When the third rotating shaft 740 rotates, it drives the cams 741 to rotate. When the cams 741 rotate, they cause reciprocating compression on the U-shaped clamping plate 730.

[0048] The top of the second rotating shaft 720 passes through a bearing located at the center of the top of the housing 710 and extends outward to connect with a single-groove pulley 721. The single-groove pulley 721 is connected to a double-groove pulley 510 via a transmission belt. Fan blades 722 are mounted on the circumferential outer wall of the second rotating shaft 720, and these blades are positioned between the top of the plate filter screen 750 and the top of the interior of the housing 710. When the first rotating shaft 520 rotates, it drives the double-groove pulley 510 to rotate. When rotating, the single groove pulley 721 will rotate via the transmission belt. When the single groove pulley 721 rotates, it will drive the second rotating shaft 720 to rotate. When the second rotating shaft 720 rotates, it will drive the fan blades 722 to rotate. When the fan blades 722 rotate, it will give the second suction pipe 712 a certain suction force. When the second suction pipe 712 has a certain suction force, it will give the suction hole 610 a certain suction force through the conveying pipe, the first suction pipe 620 and the hollow dust collection hood 600.

The second suction pipe 712 is connected to the first suction pipe 620 through a conveying pipe.

[0050] Working principle: When in use, connect to an external power source. When the operator performs centrifugal dispersion of the material in the material cylinder, position the material cylinder directly below the dispersion mechanism 500. After the operator clamps the material cylinder using the fixing clamping mechanism 400, the operator activates the hydraulic telescopic rod 200, moving the dispersion disc 560 on the dispersion mechanism 500 to a certain position inside the material cylinder. Then, the operator activates the reduction motor 550 on the dispersion mechanism 500. The reduction motor 550 drives the first rotating shaft 520 to rotate, and the rotation of the first rotating shaft 520... The rotating dispersion disc 560 and the double-groove pulley 510 centrifuge and disperse the material in the material cylinder. When the operator adds powder to the material cylinder and a certain amount of powder escapes, the rotation of the first rotating shaft 520 indirectly drives the rotation of the second rotating shaft 720 on the dust collection mechanism 700. The rotation of the second rotating shaft 720 drives the fan blades 722 to rotate. When the fan blades 722 rotate, they indirectly create a certain suction force at the suction holes 610 on the hollow dust collection hood 600. At this time, the suction holes 610 can suck up the escaped powder. The collected powder material is indirectly transported into the housing 710, thus effectively removing the dust generated during the centrifugal dispersion of the anti-corrosion coating. This prevents the dust from escaping and affecting the working environment, improving the working environment and preventing workers from inhaling the powder and affecting their health. When the escaped powder material is drawn into the housing 710, the plate filter 750 filters and blocks the powder material, which falls into the collection tank 760 for collection. When shaft 720 rotates, it indirectly drives the third rotating shaft 740 to rotate. When the third rotating shaft 740 rotates, it drives the cam 741 to rotate. When the cam 741 rotates, it causes the U-shaped clamping plate 730 to reciprocate and compress. After the U-shaped clamping plate 730 is subjected to reciprocating compression, the plate filter screen 750 will reciprocate and vibrate in a certain direction. The reciprocating and vibrating of the plate filter screen 750 in a certain direction can shake down the powder material blocked by the filter screen 750, avoiding the situation where the powder material clogs the plate filter screen 750, and improving the performance of this equipment in picking up scattered powder material.
