Description

Technical Field

[0001] The utility model relates to the technical field of smelting furnace observation windows, in particular to a smelting furnace observation window structure which is convenient for observing internal conditions. Background Art

[0002] As one of the core technologies for preparing and processing refractory metals, electron beam technology has been widely used in the refining, purification and recycling of high-melting-point metals, and will continue to be involved in various fields such as aerospace, national defense, military industry and nuclear industry. Electron beam heating technology is a heating technology that converts high-speed electron energy into thermal energy under high vacuum conditions. It uses high-energy-density electron beams to generate high temperatures when bombarding metals to melt the metal. Electron beam melting furnaces are special equipment for melting and purifying high-temperature refractory metals, providing the environment required for the application of electron beam technology.

[0003] In order to facilitate the observation of the electron beam melting process in the melting furnace during the process, a porthole is often set on the side wall of the melting furnace, and an observation window structure is set in the porthole. The observation window is often made of tempered glass to improve the overall strength of the observation window structure. However, during the melting process, debris or metal mist generated by the metal in the melting process will adhere to the surface of the observation window, causing the surface of the observation window to be dirty, affecting the observation effect of the observation window. The commonly used cleaning method is to disassemble the observation window structure for surface cleaning, but the cleaning process needs to be carried out after the end of a melting process. The surface cleaning process cannot be completed during the melting process, which ultimately affects the observation effect of the observation window on the inside of the melting furnace during the melting process.

[0004] Therefore, it is necessary to invent a smelting furnace observation window structure that is convenient for observing the internal situation to solve the above problems. Utility Model Content

[0024] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0025] The utility model provides Figure 1-6 The structure of the observation window of a smelting furnace for convenient observation of the internal conditions shown in the figure comprises a mounting plate 1 which is detachably mounted on the peripheral side wall of the smelting furnace and whose right side faces the inside of the smelting furnace, and a transparent observation circular plate 4 which is detachably mounted on the center of the mounting plate 1. A rotating shaft 10 is rotatably penetrated at a corner of one side of the mounting plate 1. A cleaning component which can scrape off dirt on the right side surface of the transparent observation circular plate 4 is detachably mounted on the right end of the rotating shaft 10. An L-shaped frame strip 17 is detachably clamped between the two side edges of the right side wall of the mounting plate 1 close to the rotating shaft 10. An L-shaped baffle plate 18 is mounted on the right side wall of the L-shaped frame strip 17. A collecting frame 22 which can collect scraped dirt is slidably arranged on the bottom side of the right side wall of the mounting plate 1.

[0026] When the rotating shaft 10 rotates, the cleaning component can clean the right side surface of the transparent observation circular plate 4. When the rotating shaft 10 rotates to the point where the cleaning component is in a horizontal or vertical state, the cleaning component enters the shielding space of the L-shaped baffle 18, thereby preventing the cleaning component from being directly exposed to the smelting environment in the smelting furnace during the smelting process, thereby improving the protection of the cleaning component.

[0027] The cleaning component includes a mounting strip 14 detachably mounted on the right end of the rotating shaft 10, a scraper 15 mounted on the left side wall of the mounting strip 14, and a plurality of scraping teeth 16 extending from the left end of the scraper 15. The plurality of scraping teeth 16 can clean the right side surface of the transparent observation circular plate 4. The rotation of the rotating shaft 10 drives the mounting strip 14 and the scraper 15 to rotate synchronously, thereby driving the scraping teeth 16 to clean the right side surface of the transparent observation circular plate 4. This process can be carried out synchronously during the smelting process to ensure the surface cleanliness of the transparent observation circular plate 4 during the smelting process.

[0028] An inner circular groove 2 is opened from right to left at the center of the mounting plate 1, and an outer circular groove 5 is opened from left to right at the center of the mounting plate 1. The inner circular groove 2 is communicated with the outer circular groove 5. A card frame 3 is detachably installed in the outer circular groove 5. A transparent observation circular plate 4 is detachably embedded in the center of the card frame 3, and the transparent observation circular plate 4 is inserted into the inner circular groove 2. The right side surface of the transparent observation circular plate 4 is flush with the right side wall of the mounting plate 1. When the transparent observation circular plate 4 needs to be removed, it is only necessary to complete the removal between the card frame 3 and the mounting plate 1, and then the transparent observation circular plate 4 can be taken out from the mounting plate 1.

[0029] The portion of the mounting plate 1 located in the outer circular groove 5 is provided with a plurality of positioning studs 6 , the clamping frame 3 is detachably mounted between the plurality of positioning studs 6 , and the positioning studs 6 are threadedly sleeved with mounting nuts 7 that can lock the clamping frame 3 in the position in the outer circular groove 5 .

[0030] A bottom support plate 19 is detachably connected to the bottom side of the right side wall of the mounting plate 1, and a slide groove 20 is provided along the length direction of the bottom support plate 19. The top of the collection frame 22 is an open end, and the bottom of the collection frame 22 is connected to a plurality of sliders 21 that can slide laterally along the slide groove 20. When the mounting plate 1 is opened, the collection frame 22 can be laterally pulled out from the bottom support plate 19 by sliding laterally, so that the dirt in the collection frame 22 can be poured out.

[0031] A through groove 8 is opened at one side corner of the mounting plate 1, and a sealing sleeve 9 is detachably embedded in the through groove 8. A sealing gasket 13 is provided at the position of the right side wall of the mounting plate 1 that is adapted to the through groove 8. The rotating shaft 10 is rotatably passed through the sealing sleeve 9 and the sealing gasket 13. A rotating frame 11 is connected to the left end of the rotating shaft 10, and an indicator block 12 is connected to the left center of the rotating frame 11. The sealing sleeve 9 and the sealing gasket 13 can ensure the sealing at the through groove 8, and finally ensure that the melting furnace is in a sealed environment to avoid the electron beam melting effect in the melting furnace.

[0032] In the present invention, the transparent observation circular plate 4 is used as the main observation carrier of the observation window, and its right side faces the smelting furnace. After the mounting plate 1 is mounted on the side wall of the smelting furnace, the smelting furnace is ensured to be in a sealed state, and then electron beam smelting is performed in the smelting furnace. During the smelting process, when metal debris and metal mist generated by smelting adhere to the right side of the transparent observation circular plate 4, manual force is applied to the left end of the rotating shaft 10 to drive the rotating shaft 10 to rotate, so that the rotating shaft 10 rotates to drive the cleaning component to rotate on the right side of the mounting plate 1, and then the transparent observation circular plate is cleaned by the cleaning component. 4 is cleaned from the right side of the transparent observation circular plate 4 to ensure the surface cleanliness of the right side of the transparent observation circular plate 4 during the smelting process. The scraped dirt can fall into the collection frame 22 for centralized collection to avoid being randomly scattered and attached to the right side of the transparent observation circular plate 4 again. The cleaning process can be carried out synchronously during the smelting process, and there is no need to remove the transparent observation circular plate 4 before surface cleaning, thereby improving the surface cleaning efficiency of the transparent observation circular plate 4, maintaining the surface cleanliness of the transparent observation circular plate 4 during the smelting process, and finally facilitating observation of the inside of the smelting furnace through the transparent observation circular plate 4.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
