Description

Technical Field

[0001] This utility model relates to the field of nano-ceramic coating production, and specifically to a nano-ceramic coating production apparatus. Background Technology

[0002] Nano-ceramic coatings are high-performance coatings with nano-sized ceramic particles as the core component. They have excellent wear resistance, high temperature resistance, corrosion resistance and insulation, as well as good adhesion and gloss. They are widely used for surface protection and decoration of various substrates such as metals, ceramics and glass, and have important application value in aerospace, automobile manufacturing, machinery and equipment, building decoration and other fields.

[0003] In the mixing and production process of nano-ceramic coatings, the generation of air bubbles is a common and unavoidable problem. This is mainly because the vigorous mixing of coating raw materials during the mixing process entrains a large amount of air, and some raw materials also release gases during chemical reactions. These gases are difficult to escape quickly in the high viscosity environment of the coating, thus forming air bubbles. Air bubbles can disrupt the continuity and density of the coating, causing a significant decrease in the coating's wear resistance, corrosion resistance, insulation and other properties, thus failing to provide effective protection.

[0016] The following describes the embodiments and appendices. Figures 1-2 The technical solution of this utility model will be further described below.

[0017] Example 1

[0018] A production apparatus for nano-ceramic coatings includes: a mixing tank 1, a mixing component 2, a defoaming tank 3, a defoaming component 4, and a frame 5. The mixing component 2 is disposed inside the mixing tank 1 and rotates to mix the coating. The upper end of the mixing tank 1 is provided with a feed pipe 11, and the upper end of the defoaming tank 3 is provided with a feed pipe 32. The bottom of the mixing tank 1 is pumped into the defoaming tank 3 by a pumping component 6. The defoaming component 4 includes a lifting component 41, a motor 42, a rotating shaft 43, a filter screen 44, and a bubble-breaking disc 45. The lifting component 41 is disposed at the lower end of the frame 5, and the motor 42 is disposed at the lower end of the lifting component 41. The upper end of the rotating shaft 43 is connected to the output end of the motor 42, and the lower end extends into the defoaming tank 3. The bubble-breaking disc 45 and the filter screen 44 are sequentially fixed downward at the lower end of the rotating shaft 43. The upper right side of the defoaming tank 3 is provided with an exhaust pipe 31, and the lower end of the defoaming tank 3 is provided with a discharge component 8.

[0019] like Figures 1-2 As shown, the working principle of this utility model is as follows:

[0020] Paint raw materials and water enter the mixing tank through the feed pipe. When the mixing components rotate, they generate shear and thrust forces on the raw materials, ensuring uniform mixing of different materials. During the mixing process, air bubbles or bubbles generated by chemical reactions are incorporated into the mixing tank along with the paint. The mixed paint is then pumped from the bottom of the mixing tank to the defoaming tank via the pumping components. The lifting components drive the motor, rotating shaft, filter screen, and bubble-breaking disc to descend as a whole, allowing the bubble-breaking disc and filter screen to penetrate deep into the paint inside the defoaming tank.

[0021] The motor drives the rotating shaft to rotate, causing the filter screen and the bubble-breaking disc to rotate synchronously. The filter screen first performs preliminary treatment on the paint, its mesh openings can filter out most of the foam, while some bubbles deform and break as they pass through the mesh openings. The bubble-breaking disc rotates at high speed with the rotating shaft, further breaking up the remaining bubbles that have been isolated to the top by the filter screen through mechanical impact and shearing action. The gas released by the broken bubbles rises to the top of the defoaming tank and is discharged through the exhaust pipe. The paint with the bubbles removed is discharged through the discharge assembly.

[0022] This technology achieves integrated production of coating mixing and defoaming, solving the problem of difficult bubble removal during traditional mixing processes and improving the density and performance of the coating. Simultaneously, the defoaming component mechanically breaks up bubbles, eliminating the need for chemical defoamers, thus avoiding interference with the coating composition and ensuring the purity of the nano-ceramic coating.

[0023] In a further preferred embodiment, the bubble-breaking disc 45 includes an outer ring 451, an inner ring 452, and round rods 453. The inner ring 452 is sleeved and fixed on the rotating shaft 43, and the outer ring 451 is located outside the inner ring 452 and is fixedly connected to it by a circular array of round rods 453. When the rotating shaft drives the bubble-breaking disc to rotate, the round rods generate high-speed shearing force as they rotate, while the outer ring forms a larger effective range. The linear contact of the round rods results in higher bubble-breaking efficiency, especially for small-sized bubbles.

[0024] In a further preferred embodiment, the lifting assembly 41 includes a hydraulic cylinder 411, a base plate 412, and a guide column 413. The upper end of the hydraulic cylinder 411 is fixed to the frame 5, and the lower end of the hydraulic cylinder 411 is connected to the base plate 412. The lower end of the guide column 413 is fixedly connected to the base plate 412, and the upper end of the guide column 413 is slidably mounted on the frame 5. The motor 42 is fixed to the lower end of the base plate 412. When the hydraulic cylinder (a conventional hydraulic actuator) extends or retracts, it drives the base plate connected to its lower end to move up and down, thereby controlling the height of components such as the motor and rotating shaft. One end of the guide column is fixed to the base plate, and the other end slides through the frame, limiting the lateral displacement of the base plate and ensuring that the rotating shaft remains vertical during lifting.

[0025] In a further preferred embodiment, the pumping assembly 6 includes a connecting pipe 61 and a pneumatic diaphragm pump 62. The connecting pipe 61 connects the bottom of the mixing tank 1 and the feed pipe 32 of the defoaming tank 3. The pneumatic diaphragm pump 62 is installed on the connecting pipe 61. The pneumatic diaphragm pump drives the diaphragm inside the pump to reciprocate through compressed air, thereby achieving coating delivery.

[0026] In a further preferred embodiment, the discharge assembly 8 includes a discharge pipe 81 and a control valve 82, wherein the control valve 82 is disposed on the discharge pipe 81. The control valve can flexibly control the discharge timing according to the defoaming progress, for example, closing the valve when defoaming is not complete to ensure that the coating is fully degassed before discharge, thus preventing untreated foamed coating from flowing out.

[0027] Based on the cross-sectional area of ​​the defoaming tank (a fixed parameter), the relationship between the paint inflow rate and the liquid level rise rate per unit time is calculated. For example, when the cross-sectional area of ​​the defoaming tank is S, if the delivery flow rate of the pneumatic diaphragm pump is Q, then the theoretical liquid level rise rate is v = Q / S. By adjusting the inlet pressure of the pneumatic diaphragm pump (a core parameter), the delivery flow rate Q can be precisely controlled, keeping the liquid level rise rate v within a preset range (e.g., to avoid liquid splashing or air entrapment due to excessive flow rate).

[0028] The lifting assembly (hydraulic cylinder) is linked with the flow control system. A liquid level sensor (a common auxiliary component, not shown in the diagram) monitors the liquid level in the defoaming tank in real time. When the liquid level rises, the hydraulic cylinder synchronously drives the rotating shaft to rise, ensuring that the filter screen is always 5-10cm above the liquid surface (an example height range, not a specific parameter), while the bubble-breaking disc remains submerged in the coating. This height difference prevents the filter screen from being covered by the coating (preventing mesh clogging) and ensures that the bubble-breaking disc continuously breaks up air bubbles in the liquid.

[0029] When the filter screen is positioned above the liquid surface, it can intercept the foam (bubbles on the liquid surface) generated by the impact when the coating enters the defoaming tank from the feed pipe 2, while also preventing the filter screen from directly agitating the liquid surface during rotation and causing air to be re-entered. If the filter screen is in contact with or submerged in the liquid surface, its rotation will cause disturbance to the liquid like a stirring blade, which will actually create more bubbles and negate the defoaming effect.

[0030] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
