Description

Technical Field

[0001] This utility model relates to the field of material surface treatment technology, and in particular to an ultrasonic-assisted ceramic coating sealing device. Background Technology

[0002] Ceramic coatings (such as alumina, chromium oxide, and tungsten carbide) prepared by technologies such as thermal spraying and plasma spraying are widely used in machinery, aerospace, and chemical industries due to their excellent properties such as high hardness, wear resistance, and corrosion resistance. However, these coatings usually have a certain degree of porosity (micropores, cracks), and these defects can become channels for corrosive media to penetrate, accelerating the corrosion of the substrate and thus reducing the protective performance and service life of the coating.

[0003] To address this problem, pore sealing is typically employed. Traditional pore sealing methods primarily involve immersion, where the workpiece is submerged in a sealing agent (such as silicone resin, epoxy resin, or inorganic salt solution), relying on capillary action or hydrostatic pressure to allow the agent to penetrate the pores. However, this method has significant drawbacks: for small, tortuous, or closed pores, the sealing agent struggles to penetrate effectively, resulting in incomplete sealing and unsatisfactory results. Therefore, there is an urgent need for a new device that can significantly improve the penetration ability of sealing agents and the sealing effect. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic-assisted ceramic coating sealing device to solve the technical problem in the prior art where the sealing agent cannot effectively penetrate small, tortuous, or closed pores using the immersion method, resulting in incomplete sealing and unsatisfactory results. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides an ultrasonic-assisted ceramic coating sealing device, comprising a first annular body, a second annular body, an ultrasonic component, a pump component, and a base plate. The first ends of the first annular body and the second annular body are simultaneously mounted on the base plate, and the second annular body is mounted inside the first annular body. The height of the second annular body is higher than that of the first annular body. The pump component pumps liquid from the first annular body into the second annular body. The ultrasonic component passes through the base plate and is mounted inside the second annular body to perform ultrasonic treatment on the liquid inside the second annular body, so that the liquid forms a spherical surface at the end of the second annular body.

[0006] Preferably, the ultrasonic component penetrates the second annular body to a greater height than the first annular body.

[0007] Preferably, the diameter of the first annular body is 100-200 mm, and the diameter of the second annular body is 50-100 mm.

[0008] Preferably, the first annular body and the second annular body are coaxially arranged.

[0009] Preferably, the pump assembly includes an inlet pipe, a pump body, and an outlet pipe, with the inlet pipe extending to the bottom of the first annular body.

[0010] Preferably, a gravity hammer is provided at the end of the water inlet pipe away from the pump body.

[0011] Preferably, the ultrasonic component includes an ultrasonic transducer and an ultrasonic generator connected together, wherein the ultrasonic transducer is mounted on the base plate.

[0012] The technical solution provided in this application document has the following beneficial effects: This invention provides an ultrasonic-assisted ceramic coating sealing device, comprising a first annular body, a second annular body, an ultrasonic component, a pump assembly, and a base plate. The first ends of both the first and second annular bodies are mounted on the base plate, with the second annular body installed inside the first annular body. This creates a first cavity for containing liquid between the first and second annular bodies and the base plate, and a second cavity for containing liquid between the second annular body and the base plate. The first annular body can receive the liquid. Since the liquid inside the second annular body needs to contact the idler roller, the height of the second annular body is higher than that of the first annular body, facilitating contact between the second annular body and the surface of the idler roller. To facilitate pumping the liquid from the first cavity into the second cavity, the pump assembly is installed between the first and second annular bodies. The pump assembly pumps the liquid from the first annular body into the second annular body. To reduce voids within the liquid, the ultrasonic component passes through the base plate and is installed inside the second annular body to ultrasonically treat the liquid. When the liquid overflows from the second annular body, it forms a spherical surface at the end of the second annular body, facilitating contact between the liquid and the surface of the idler roller. The ultrasonic component transmits high-frequency mechanical vibrations into the sealing agent liquid, generating a strong "ultrasonic cavitation effect." This cavitation effect creates countless tiny bubbles in the liquid that instantly collapse, generating extremely high local pressure and shock waves. This powerful force displaces air from pores, forcibly expelling residual air from micropores and cracks. Simultaneously, it injects additional energy into the sealing agent, enabling it to overcome surface tension and penetrate deeper into fine, tortuous pores, thus enhancing the liquid's permeability. Furthermore, the mechanical vibration of the ultrasonic component also agitates the liquid, preventing sedimentation of the sealing agent, maintaining its uniform concentration, and potentially breaking up some aggregated sealing agent particles, improving its fluidity.

[0013] This setup utilizes the cavitation effect and strong vibrations generated by ultrasound in a liquid to effectively displace air from the micropores of the ceramic coating and powerfully propel the sealing agent deep into the micropores and cracks within the coating. This achieves a deep sealing effect that is difficult to attain with traditional impregnation methods, significantly improving the corrosion resistance, wear resistance, and service life of the ceramic coating. The device is simple in structure, easy to operate, and readily applicable to industrial applications. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] This specific embodiment provides an ultrasonic-assisted ceramic coating sealing device, which solves the technical problem in the prior art where the sealing agent is difficult to penetrate effectively into small, tortuous or closed pores by the immersion method, resulting in incomplete sealing and unsatisfactory results.

[0019] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.

[0020] Reference Figures 1-3 This utility model provides an ultrasonic-assisted ceramic coating sealing device, including a first annular body 1, a second annular body 2, an ultrasonic component 3, a pump component 4, and a base plate 5. The first ends of the first annular body 1 and the second annular body 2 are simultaneously mounted on the base plate 5, and the second annular body 2 is mounted inside the first annular body 1. In this way, a first cavity for containing liquid is formed between the first annular body 1, the second annular body 2 and the base plate 5, and a second cavity for containing liquid is formed between the second annular body 2 and the base plate 5. The first annular body 1 can receive liquid, and since the liquid in the second annular body 2 needs to contact the roller, the height of the second annular body 2 is higher than the height of the first annular body 1, which facilitates the contact between the second annular body 2 and the surface of the roller. To facilitate the pumping of liquid from the first cavity into the second cavity, a pump assembly 4 is installed between the first and second annular bodies. The pump assembly 4 pumps liquid from the first annular body 1 into the second annular body 2. To reduce voids within the liquid, an ultrasonic component 3 passes through the base plate 5 and is installed inside the second annular body 2. This ultrasonically treats the liquid within the second annular body 2, forming a spherical surface at the end of the second annular body 2, facilitating contact between the liquid and the surface of the idler roller. The ultrasonic component transmits high-frequency mechanical vibrations to the sealing agent liquid, generating a strong "ultrasonic cavitation effect." This cavitation effect produces countless tiny bubbles in the liquid that instantly collapse, generating extremely high local pressure and shock waves. This powerful force can displace air in pores, forcibly expelling residual air from micropores and cracks, while injecting additional energy into the sealing agent, enabling it to overcome surface tension and penetrate deeper into small, tortuous pores to enhance the liquid's permeability. In addition, the mechanical vibration of the ultrasonic components can also stir the liquid, preventing the sealing agent from settling, maintaining its uniform concentration, and potentially breaking up some of the agglomerated sealing agent particles, thus improving its fluidity.

[0021] This setup utilizes the cavitation effect and strong vibrations generated by ultrasound in a liquid to effectively displace air from the micropores of the ceramic coating and powerfully propel the sealing agent deep into the micropores and cracks within the coating. This achieves a deep sealing effect that is difficult to attain with traditional impregnation methods, significantly improving the corrosion resistance, wear resistance, and service life of the ceramic coating. The device is simple in structure, easy to operate, and readily applicable to industrial applications.

[0022] To further optimize the design, in order for the ultrasonic component 3 to effectively stir the liquid, the height of the ultrasonic component 3 extending into the second annular body 2 is higher than the height of the first annular body 1, thus enabling better stirring.

[0023] Further optimization of the scheme: the diameter of the first annular body 1 is 100-200 mm, and the diameter of the second annular body 2 is 50-100 mm. That is, when the diameter of the first annular body 1 is 100 mm, the diameter of the second annular body 2 is set to 50 mm, and when the diameter of the first annular body 1 is 200 mm, the diameter of the second annular body 2 is set to 100 mm. Both the first cavity and the second cavity can accommodate the corresponding liquid.

[0024] The design is further optimized by setting the first annular body 1 and the second annular body 2 coaxially, so that the first annular body 1 can easily receive the liquid overflowing from the second annular body 2.

[0025] Further optimization of the design: the pump body assembly 4 includes an inlet pipe 41, a pump body 42, and an outlet pipe 43. The inlet pipe 41 is located inside the first annular body 1 and extends to the bottom of the first annular body 1 to facilitate the suction of liquid from the bottom of the first annular body 1. The outlet pipe 43 is located inside the second annular body 2 to deliver the liquid pumped in by the pump body 42 into the second annular body 2. The pump body 42 is installed on the side wall of the second annular body 2.

[0026] To further optimize the design, in order to facilitate the bottom of the water inlet pipe 41 to sink, a gravity hammer 44 is provided at the end of the water inlet pipe 41 away from the pump body 42. The gravity hammer 44 is designed with a first through hole for liquid to pass through, and the first through hole is connected to the water inlet pipe.

[0027] To further optimize the design and facilitate the installation of the ultrasonic components, the ultrasonic component 3 includes an ultrasonic transducer and an ultrasonic generator connected to each other. The ultrasonic transducer is mounted on the base plate 5, and the ultrasonic generator is mounted in a fixed position. This way, the vibration of the ultrasonic transducer does not affect the ultrasonic generator.
