Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for casting equipment, and in particular to a magnetic separator for a casting wheel cooling pipe. Background Technology

[0002] In the casting process, the casting wheel, as a crucial forming component, directly impacts the quality of the castings. The casting wheel cooling pipes play a vital role in maintaining the casting wheel's normal operating temperature. During cooling, the cooling medium (such as water) circulates within the pipes. However, due to the complexity of the casting environment, various impurities, including magnetic metal particles, often become present in the cooling medium. If these magnetic impurities are not removed promptly, they will circulate with the cooling medium within the pipes, not only wearing down the inner walls and reducing the pipes' lifespan, but also potentially clogging them, affecting the cooling effect and consequently impacting the performance of the casting wheel and the quality of the castings.

[0003] To remove these impurities, magnetic separators are typically installed along the water circulation path in the cooling pipes to adsorb them. To ensure the magnetic separators can continue to perform their adsorption function efficiently, they need to be cleaned regularly. However, existing cleaning methods are cumbersome, time-consuming, and labor-intensive, impacting production efficiency. Utility Model Content

[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0027] like Figures 1 to 5 As shown, the magnetic separator for the cooling pipe of the casting wheel of this utility model includes:

[0028] The housing 1 has a cylindrical structure and connection ports 11 on both sides for connecting to cooling pipes.

[0029] The magnetic adsorption component 2 is disposed inside the housing 1. The magnetic adsorption component 2 includes multiple permanent magnet units 21, which are arranged in an array.

[0030] Impurity cleaning mechanism 3 is installed on housing 1. Impurity cleaning mechanism 3 includes scraper assembly 31 and drive member 32. Scraper assembly 31 is in contact with the surface of permanent magnet unit 21. Drive member 32 is used to drive scraper assembly 31 to move along the surface of permanent magnet unit 21 to clean magnetic impurities adsorbed on permanent magnet unit 21.

[0031] By integrating the magnetic adsorption component 2 and the impurity cleaning mechanism 3 inside the housing 1, the overall structure is compact, allowing the magnetic separator to be easily connected to the water circulation path of the cooling pipe via port 11 without occupying too much space. This facilitates layout and installation in the casting production environment and improves the space utilization of the production workshop. The working principle of the magnetic separator is based on the principles of magnetic adsorption and mechanical cleaning. When the cooling medium containing magnetic impurities circulates in the cooling pipe and passes through the magnetic separator, due to the property of permanent magnets to attract ferromagnetic materials, the magnetic impurities are adsorbed onto the surface of the permanent magnet unit 21, thereby achieving... The magnetic impurities are separated from the cooling medium. The array-distributed permanent magnet units 21 can provide a wider and more uniform magnetic field coverage, making it easier for the flowing cooling medium to be captured and adsorbed, improving the removal efficiency of magnetic impurities, effectively ensuring the purity of the cooling medium, and thus improving the cooling effect of the casting wheel and the quality of the casting. When the scraper assembly 31 is driven by the drive unit 32 to move along the surface of the permanent magnet unit 21, the magnetic impurities adsorbed on the surface of the permanent magnet unit 21 are scraped off, thereby realizing the periodic cleaning of the magnetic impurities on the surface of the permanent magnet unit 21, ensuring that the magnetic separator can continuously and efficiently perform its adsorption function and saving cleaning time.

[0032] The permanent magnet unit 21 includes a permanent magnet body 211 and a protective sleeve 212. The protective sleeve 212 is fitted over the permanent magnet body 211. Since the cooling medium may be corrosive during the cooling medium circulation process, or impurities may be trapped in it and cause scratches, wear and other damage to the permanent magnet body 211, the protective sleeve 212 is made of corrosion-resistant material and serves as an isolation barrier to prevent these external factors from directly contacting and corroding the permanent magnet body 211, preventing the permanent magnet body 211 from degrading or being damaged due to environmental factors, thereby significantly extending the service life of the permanent magnet body 211 and reducing the replacement frequency.

[0033] The scraper assembly 31 includes a scraper body 311, an elastic element 312, and a support plate 313. The scraper body 311 is connected to the support plate 313 via the elastic element 312, and the support plate 313 is connected to the drive element 32 via a connecting rod 314. The connecting rod 314 connects and transmits motion, accurately transmitting the linear motion of the drive element 32 to the support plate 313, thereby driving the scraper assembly 31 connected to the support plate 313 to move along the surface of the permanent magnet unit 21. The elastic element 312 has elastic deformation capability. When the drive element 32 drives the support plate 313 to move the scraper assembly 31 via the connecting rod 314, the elastic element 312 can elastically deform according to the unevenness of the surface of the permanent magnet unit 21, automatically adjusting the degree of contact between the scraper body 311 and the surface of the permanent magnet unit 21, ensuring that the scraper body 311 always maintains good contact with the surface of the permanent magnet unit 21, and effectively scraping away magnetic impurities.

[0034] The scraper body 311 is preferably made of a flexible material, and the side that contacts the surface of the permanent magnet unit 21 has multiple protrusions 3111. The flexible material includes, but is not limited to, various types such as rubber, plastic, and fiber, and has good flexibility and deformation ability. When the scraper body 311 contacts the surface of the permanent magnet unit 21, it can further adapt to the shape and roughness of the permanent magnet surface in conjunction with the elastic element 312. During the movement of the scraper body 311, the protrusions 3111 are like tiny scrapers, which can more effectively insert into the gaps between the magnetic impurities and the surface of the permanent magnet, forcibly scraping off the small magnetic impurities or those embedded in the surface of the permanent magnet that may have been difficult to remove, thereby further improving the cleaning ability of magnetic impurities.

[0035] The preferred driving component 32 is an electric push rod. The output end of the electric push rod is connected to the scraper assembly 31. The electric push rod is connected to an external power source via a control switch. The power source provides electrical energy to the electric push rod, enabling the extension and retraction of the output end of the electric push rod. As the output end extends and retracts, the scraper assembly moves back and forth along the surface of the permanent magnet unit 21, thus cleaning the magnetic impurities adsorbed on the surface of the permanent magnet unit 21. The movement speed of the electric push rod is relatively uniform and stable, allowing the scraper assembly 31 to maintain a uniform speed during operation. Uniform speed movement helps to avoid incomplete cleaning or excessive scraping of the permanent magnet surface caused by uneven speed, ensuring the smoothness and efficiency of the cleaning process, and further improving the removal effect of the magnetic separator on magnetic impurities.

[0036] The preferred housing 1 includes a cover 12 and a main body 13, which are detachably connected. A sealing gasket 14 is provided at the connection between the cover 12 and the main body 13. Through the detachable design, when it is necessary to inspect, clean or replace internal components such as the magnetic adsorption component 2 and the impurity cleaning mechanism 3, the cover 12 can be removed to directly contact the internal components without the need for complex tools or large-scale disassembly, thereby shortening maintenance time, improving equipment maintainability and reducing maintenance costs. The sealing gasket 14 achieves its sealing function based on the elastic and plastic deformation characteristics of the sealing material. When the cover 12 and the main body 13 are connected, the pressure between them causes the sealing gasket to elastically deform, filling the tiny gap at the connection, thereby preventing the cooling medium from leaking from the connection and ensuring that the cooling medium inside the housing 1 can circulate in a predetermined path.

[0037] The main body 13 is preferably provided with an observation window 131. The observation window 131 is made of transparent material, such as glass or plexiglass. Transparent material has good light transmittance. When light shines on the internal components of the main body 13, the operator can observe the internal condition of the main body 13 from the outside through the observation window, understand whether its working status is normal, help to discover problems in time and take corresponding measures, and ensure the continuity and stability of production.

[0038] The preferred cover 12 is provided with a slag discharge port 121 corresponding to the scraper assembly 31, and a detachable baffle 122 is provided at the slag discharge port 121. The slag discharge port 121 provides a discharge channel for the scraped magnetic impurities, and the baffle 122 is used to close or open the slag discharge port 121. When the baffle 122 is removed and the slag discharge port 121 is opened, the impurities are scraped away from the permanent magnet unit 21 by the scraper assembly 31 and then carried by the support plate 313 to the slag discharge port 121, thereby realizing the centralized cleaning and discharge of impurities.

[0039] This invention relates to a magnetic separator for casting wheel cooling pipes. During operation, the separator connects to the cooling pipes via connection ports 11 on both sides of the housing 1. Cooling media containing magnetic impurities circulates within the cooling pipes of the casting production system. When the cooling media flows through the magnetic separator, the magnetic adsorption component 2 activates. Due to the characteristic of permanent magnets attracting ferromagnetic materials, the magnetic impurities in the cooling media are adsorbed onto the surface of the permanent magnet unit 21, thus achieving separation of the magnetic impurities from the cooling media. The drive component 32 is connected to an external power source via a control switch. After the power is turned on, the electric push rod begins to work. The connecting rod 314 accurately transmits the linear motion of the electric push rod to the support plate 313, thereby driving the scraper assembly. The scraper assembly 31 moves along the surface of the permanent magnet unit 21. During the movement, the elastic element 312 has elastic deformation capability and can undergo elastic deformation according to the unevenness of the surface of the permanent magnet unit 21. It automatically adjusts the degree of contact between the scraper body 311 and the surface of the permanent magnet unit 21 to ensure that the scraper body 311 always maintains good contact with the surface of the permanent magnet unit 21. The scraped magnetic impurities move towards the slag discharge port 121 under the drive of the support plate 313. When it is necessary to clean and discharge the scraped magnetic impurities, the detachable baffle 122 corresponding to the slag discharge port 121 is opened, and the scraper assembly 31 continues to move to bring the magnetic impurities to the slag discharge port 121 position, so as to realize the centralized cleaning and discharge of impurities.

[0040] The magnetic separator for the cooling pipe of the cast wheel of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
