Description

Technical Field

[0001] This utility model belongs to the technical field of impurity purification devices, specifically a device for purifying impurities in leveling agents. Background Technology

[0002] Leveling agents are commonly used coating additives. They mainly function in coating systems by reducing the surface tension of the coating, improving its fluidity, and promoting the formation of a smooth, uniform film during the drying process. This reduces surface defects such as ripples, orange peel, brush marks, pinholes, and craters. In the preparation of leveling agents, after the raw materials are dissolved and the polymerization reaction is completed, a filtration step is usually required to remove unreacted impurities, byproducts of the polymerization process, and solid particles that may be generated during polymerization, in order to ensure the purity and uniformity of the leveling agent solution.

[0003] While existing technologies can improve the flowability of leveling agents through stirring to facilitate the removal of impurities, for some leveling agents with inherently high viscosity, the shear force generated by stirring is insufficient to effectively break up agglomerated solid impurity particles, resulting in poor impurity purification.

[0004] Therefore, this utility model provides a device for purifying impurities in leveling agents. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problem that while stirring can improve the flowability of leveling agents and facilitate the removal of impurities, for some leveling agents with high viscosity, the shear force generated by stirring is insufficient to effectively break up agglomerated solid impurity particles, resulting in poor impurity purification.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A device for purifying impurities in leveling agents, comprising a barrel body, wherein a purification mechanism is provided inside the barrel body, and the purification mechanism includes:

[0007] A stirring assembly includes a square shell fixed to the inner wall of a barrel by a set of fixed rods. A first rotating rod is rotatably connected to the bottom of the square shell through a first rotating hole. A set of stirring rods is fixed to the first rotating rod. A pair of rotating blocks are fixed to the first rotating rod. A second rotating rod is rotatably connected to the side wall of the rotating block. A set of flipping rods is fixed to the second rotating rod. A flipping unit that drives the pair of second rotating rods to rotate is provided on the inner wall of the barrel.

[0008] A drive assembly, mounted on the barrel, is used to drive the first rotating rod to rotate.

[0009] The filter assembly, located at the bottom of the tank, is used to filter impurities.

[0010] Preferably, the turning unit includes an annular frame fixed to the inner wall of the barrel. A T-shaped annular groove is formed on the inner wall of the annular frame. A rotating ring is rotatably connected between the T-shaped annular groove and the groove wall. One end of the second rotating rod is rotatably connected to the inner circular wall of the rotating ring and passes through the outer circular wall of the rotating ring. A toothed ring is fixed to the bottom of the T-shaped annular groove. A rotating gear is fixed to one end of the second rotating rod located in the T-shaped annular groove. The rotating gear is meshed with the top of the toothed ring.

[0011] Preferably, the driving assembly includes an L-shaped frame fixed to the outer circular wall of the barrel, a motor fixed to the vertical side wall of the L-shaped frame, a third rotating rod rotatably connected to the side wall of the square shell through a second rotating hole, and the third rotating rod rotatably connected to the inner wall of the barrel and penetrating the outer circular wall of the barrel, and the third rotating rod is driven by the motor.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The present invention discloses a device for purifying impurities in leveling agents. A first rotating rod drives a set of stirring rods to rotate, while a second rotating rod rotates due to the meshing of gears and a gear ring. This causes a set of turning rods on the second rotating rod to form a composite motion trajectory of revolution and rotation, comprehensively agitating the leveling agent in the lower and bottom parts of the tank.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1 to 5 As shown, an embodiment of this utility model provides a purification device for leveling agents, comprising a barrel body 1, a purification mechanism inside the barrel body 1, and the purification mechanism including: a stirring assembly, comprising a square shell 2 fixed to the inner wall of the barrel body 1 by a set of fixing rods, a first rotating rod 3 rotatably connected to the bottom of the square shell 2 through a first rotating hole, a sealing ring added to the gap between the first rotating rod 3 and other components, a set of stirring rods 4 fixedly connected to the first rotating rod 3, a pair of rotating blocks 5 fixedly connected to the first rotating rod 3, a second rotating rod 6 rotatably connected to the side wall of the rotating block 5, a sealing ring added to the gap between the second rotating rod 6 and other components, a set of flipping rods 7 fixedly connected to the second rotating rod 6, and a flipping unit for driving the pair of second rotating rods 6 to rotate on the inner wall of the barrel body 1; a driving assembly, disposed on the barrel body 1 for driving the first rotating rod 3 to rotate; and a filtering assembly, disposed at the bottom of the barrel body 1 for filtering impurities.

[0027] The flipping unit includes an annular frame 8 fixed to the inner wall of the barrel 1, which is located in the lower part of the barrel 1. A T-shaped annular groove 9 is opened on the inner wall of the annular frame 8. The T-shaped annular groove 9 is arranged horizontally. A rotating ring 10 is rotatably connected between the T-shaped annular groove 9 and the groove wall. One end of the second rotating rod 6 is rotatably connected to the inner circular wall of the rotating ring 10 and passes through the outer circular wall of the rotating ring 10. A toothed ring 11 is fixed to the bottom of the T-shaped annular groove 9. A rotating gear 12 is fixed to the end of the second rotating rod 6 located in the T-shaped annular groove 9. The rotating gear 12 is meshed with the top of the toothed ring 11.

[0028] The drive assembly includes an L-shaped frame 13 fixed to the outer circular wall of the barrel 1 for supporting the motor 14. The motor 14 is fixed to the vertical side wall of the L-shaped frame 13. The motor 14 is a variable frequency motor. A third rotating rod 15 is rotatably connected to the side wall of the square shell 2 through a second rotating hole. The third rotating rod 15 is rotatably connected to the inner wall of the barrel 1 and passes through the outer circular wall of the barrel 1. The third rotating rod 15 is drivenly connected to the motor 14.

[0029] The third rotating rod 15 is fixed to one end of the square shell 2 with a first bevel gear 16, and the first rotating rod 3 is fixed to one end of the square shell 2 with a second bevel gear 17. The first bevel gear 16 and the second bevel gear 17 are the same size and are meshed together.

[0030] During operation, the first rotating rod 3 drives a set of stirring rods 4 to rotate, while the meshing of the rotating gear 12 and the gear ring 11 causes the second rotating rod 6 to rotate. This causes a set of turning rods 7 on the second rotating rod 6 to form a compound motion trajectory of revolution and rotation, which comprehensively turns the leveling agent in the lower part and bottom of the barrel 1. Together with the stirring rods 4, this effectively prevents impurities from settling at the bottom of the barrel due to gravity, further improving the uniformity of mixing impurities and leveling agent, and laying the foundation for subsequent filtration processes.

[0031] The filter assembly includes an annular plate 18 that is detachably connected to the bottom of the barrel 1 by a set of first bolts. A circular cylinder 19 is fixed to the top of the annular plate 18. A conical top 20 is fixed to the top of the circular cylinder 19. A set of filter holes 21 are opened on the conical top 20. An annular groove 22 is opened on the outer circular wall of the circular cylinder 19. A rubber ring 23 is installed in the annular groove 22.

[0032] During operation, the detachable bolt connection allows for quick and easy disassembly of the filter components to remove trapped impurities and clean the filter parts. Furthermore, the filter components with appropriate pore sizes can be flexibly replaced according to the purification process requirements of different leveling agents. No complicated tools are required, making operation convenient and efficient, significantly shortening maintenance time and greatly improving maintenance efficiency.

[0033] An arc-shaped piece 24 is fixed to the bottom of the first rotating rod 3 by a second bolt. A rectangular rod 25 is fixed to the arc-shaped piece 24. A rubber strip 26 is fixed to the side of the rectangular rod 25 near the conical top 20, and the rubber strip 26 is tightly attached to the conical top 20.

[0034] During operation, when the first rotating rod 3 rotates, it drives the arc-shaped piece 24 fixed by the second bolt to rotate synchronously. The rectangular rod 25 on the arc-shaped piece 24 drives the rubber strip 26 at its end to slide along the surface of the conical top 20 (the rubber strip 26 is in close contact with the conical top 20), which scrapes away the impurities intercepted on the surface of the filter hole 21 in real time, effectively preventing the filter hole 21 from being blocked, ensuring that the filter channel is unobstructed, and ensuring stable filtration efficiency.

[0035] Working principle: First, start the motor 14, which is fixed inside the L-shaped frame 13. The start-up transmits the rotational power to the third rotating rod 15. The two ends of the third rotating rod 15 are rotatably connected to the side wall of the square shell 2 and the inner wall of the barrel 1, respectively. It can stably receive power and rotate along its own axis. When the third rotating rod 15 rotates, the first bevel gear 16, which is fixed to one end inside the square shell 2, rotates synchronously. A set of stirring rods 4, which are evenly distributed axially on the first rotating rod 3, make circular motion around the first rotating rod 3 as the axis, and radially stir the leveling agent in the middle and lower part of the barrel 1. A pair of rotating blocks 5, which are symmetrically fixed on the first rotating rod 3, make circular motion with the first rotating rod 3. The rotating gear 12 rolls along the tooth surface of the tooth ring 11, which in turn drives the second rotating rod 6 to rotate around its own axis. A set of turning rods 7 on the second rotating rod 6 form a compound motion trajectory of revolution and rotation, which turns the leveling agent in the middle and lower part and bottom of the barrel 1 in all directions, effectively preventing impurities from being deposited at the bottom of the barrel due to gravity.

[0036] The leveling agent, after being thoroughly stirred and agitated, flows towards the bottom of the tank 1 under gravity and eventually converges at the conical top 20 area of ​​the filter assembly. It then works in conjunction with the conical outlet at the bottom of the tank 1 to perform filtration. The stirring and agitation also accelerate the purification efficiency.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
