Description

Technical Field

[0001] This disclosure relates to the field of vacuum smelting technology, and in particular to a vacuum furnace inspection hole lens cleaning device and a vacuum furnace. Background Technology

[0002] Currently, to reduce environmental pollution from industrial production and improve the overall performance of metallic materials, most high-end metallic materials produced are obtained through vacuum smelting. However, during vacuum smelting, to ensure the smelting environment is below atmospheric pressure, the molten metal needs to be placed in a sealed steel shell, and a vacuum pump is used to maintain the vacuum level of the sealed steel shell. A viewing port with a glass lens needs to be designed and fabricated on the steel shell to observe the internal smelting process. However, under vacuum conditions, volatile metal compounds float erratically within the furnace, causing frequent contamination of the viewing port lens, making it impossible to clearly see the internal production process. Cleaning the viewing port lens requires purging with various gases, but this cannot completely remove the stains or condensed metal vapors, further obscuring the internal production process, affecting observation effectiveness, and potentially damaging the equipment. This further impacts the stability of vacuum smelting, leading to a decline in overall performance, wasting time and effort, and severely affecting normal equipment operation. Utility Model Content

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0024] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0025] Currently, to reduce environmental pollution from industrial production and improve the overall performance of metallic materials, most high-end metallic materials produced are obtained through vacuum smelting. However, during vacuum smelting, to ensure the smelting environment is below atmospheric pressure, the molten metal needs to be placed in a sealed steel shell, and a vacuum pump is used to maintain the vacuum level of the sealed steel shell. A viewing port with a glass lens needs to be designed and fabricated on the steel shell to observe the internal smelting process. However, under vacuum conditions, volatile metal compounds float erratically within the furnace, causing frequent contamination of the viewing port lens, making it impossible to clearly see the internal production process. Cleaning the viewing port lens requires purging with various gases, but this cannot completely remove the stains or condensed metal vapors, further obscuring the internal production process, affecting observation effectiveness, and potentially damaging the equipment. This further impacts the stability of vacuum smelting, leading to a decline in overall performance, wasting time and effort, and severely affecting normal equipment operation.

[0026] Existing technology involves inserting a gas pipe into the side wall of a vacuum casting chamber. A nozzle is located at the inner end of the gas pipe, with its outlet angled towards the center of the viewing window glass. Argon gas is connected to the outer end of the gas pipe, and argon is used to purge and remove deposits from the viewing window glass surface. However, in actual production, the high-temperature resistant quartz glass used for the viewing window is subjected to radiation from the molten steel over long periods of continuous production. The glass surface already has a certain temperature, and when volatile metals fall onto the glass, they adhere tightly, forming metal vapor condensates. Simple argon purging can only remove a small amount of these volatile metals, failing to guarantee the cleanliness of the lens.

[0027] Based on this, this disclosure provides a vacuum furnace viewing port lens cleaning device. The first cleaning unit and the second cleaning unit are both disposed on the furnace shell of an existing vacuum furnace at the corresponding viewing port position. The first cleaning unit includes a first driving mechanism and a first cleaning component. The first driving mechanism drives the first cleaning component to move within the viewing port lens area to be cleaned, and the first cleaning component is used to contact and clean the viewing port lens, thoroughly cleaning stains or metal vapor condensates on the lens through contact cleaning. The second cleaning unit includes a second driving mechanism and a second cleaning component. The second cleaning component is connected to the second driving mechanism, which drives the second cleaning component to move within the viewing port lens area to be cleaned, and the second cleaning component is used to blow air onto the viewing port lens. Through the cooperation of the first and second cleaning units, metal volatiles adhering to the surface of high-temperature resistant quartz high-strength glass can be effectively cleaned, ensuring the cleanliness of the lens and improving its service life.

[0028] The following is a detailed description of the vacuum furnace inspection port lens cleaning device through specific embodiments:

[0029] Reference Figures 1 to 3 As shown, a vacuum furnace viewing port lens cleaning device is provided in the first aspect of this disclosure, including a first cleaning part 1 and a second cleaning part 2. The first cleaning part 1 and the second cleaning part 2 are disposed on the furnace shell 3 of the vacuum furnace. The first cleaning part 1 includes a first driving mechanism 11 and a first cleaning component 12. The first cleaning component 12 is connected to the first driving mechanism 11. The first driving mechanism 11 is used to drive the first cleaning component 12 to move within the range of the viewing port lens 100 to be cleaned. The first cleaning component 12 is used to contact and clean the viewing port lens 100 to be cleaned. The second cleaning part 2 includes a second driving mechanism 21 and a second cleaning component 22. The second cleaning component 22 is connected to the second driving mechanism 21. The second driving mechanism 21 is used to drive the second cleaning component 22 to move within the range of the viewing port lens 100 to be cleaned. The second cleaning component 22 is used to blow air onto the viewing port lens 100 to be cleaned.

[0030] The first cleaning unit 1 and the second cleaning unit 2 of this disclosure are both disposed on the furnace shell 3 at the corresponding viewing port position of the existing vacuum furnace. The first cleaning unit 1 includes a first driving mechanism 11 and a first cleaning assembly 12. The first driving mechanism 11 is used to drive the first cleaning assembly 12 to move within the range of the viewing port lens 100 to be cleaned. Specifically, the first driving mechanism 11 can be driven by means of an electric drive linkage, a rotating shaft, a rotating rod, etc., to drive the first cleaning assembly 12 inside the vacuum furnace, so as to move it within the range of the viewing port lens 100 to be cleaned, thereby ensuring that the first cleaning assembly 12 can contact all positions of the viewing port lens 100 to be cleaned. For example, the first driving mechanism 11 includes a linkage and a drive motor, wherein one end of the linkage is connected to the drive motor, and the other end is connected to the first cleaning assembly 12. When the drive motor outputs power, the linkage rotates, and the linkage can drive the first cleaning assembly 12 to swing, so as to realize the function of wiping the viewing port lens 100. Understandably, the first cleaning component 12 needs to be installed on the rigidly connected parts and cleaning components, such as the base and the wiping cloth, and the setting angle of the base is adapted to the angle of the viewing lens 100 in the vacuum furnace. Furthermore, if it is necessary to drive the first cleaning component 12 to reciprocate within the range of the viewing lens 100, a drive motor capable of rotating in both directions can be selected.

[0031] The first cleaning component 12 of this disclosure is used to contact and clean the peephole lens to be cleaned, and to thoroughly clean the stains or metal vapor condensation on the lens by contact cleaning. The cleaning component can be a brush, a wiping cloth or a non-woven cloth, etc. In the usage environment of this disclosure, the cleaning component needs to have a certain heat resistance, but the peephole lens 100 is far from the high temperature position of the core of the vacuum furnace, and the position will not generate a high temperature.

[0032] The second cleaning unit 2 of this disclosure includes a second driving mechanism 21 and a second cleaning component 22. The second cleaning component 22 is connected to the second driving mechanism 21. The structure of the second driving mechanism 21 can be the same as that of the first driving mechanism 11. The second cleaning component 22 is used to blow air onto the peephole lens to be cleaned. In the usage environment of this disclosure, the second cleaning component 22 generally uses argon gas as the blowing medium, and an argon gas pipeline needs to be set up for blowing argon gas. The argon gas pipeline of the second cleaning component 22 of this disclosure can be independently installed in the furnace shell 3. The end of the argon gas pipeline entering the furnace shell 3 is set as a flexible pipeline to ensure that the first driving mechanism 21 can drive the flexible part of the argon gas pipeline to rotate, so that the output port of the argon gas pipeline can be aimed at different areas of the peephole lens 100 for blowing. In another embodiment, the argon gas pipeline of the second cleaning component 22 can be set in the second driving mechanism 21, for example, as shown in the figure. Figure 1As shown, the argon gas pipeline passes through the connecting rod or rotating rod of the second drive mechanism 21. The part of the argon gas pipeline extending into the furnace shell 3 can be configured as a rigid structure or a flexible mechanism. In this disclosure, it is specifically configured as a rigid mechanism. The output end of the argon gas pipeline is always aligned with the viewing lens 100. The rotation of the connecting rod or rotating rod of the second drive mechanism 21 drives the output end of the argon gas pipeline to change the blowing angle. This disclosure, through the cooperation of the first cleaning section and the second cleaning section, can effectively clean the metal volatiles adhering to the surface of the high-temperature resistant quartz high-strength glass, ensuring the cleanliness of the lens and improving its service life.

[0033] In some embodiments, the first drive mechanism 11 includes a first operating handle 111 and a first rotating rod 112. The first rotating rod 112 has a first operating end and a first driving end. The first operating handle 111 is connected to the first operating end, and the first cleaning component 12 is connected to the first driving end. The first operating handle 111 is used to drive the first driving end to rotate outside the furnace shell 3.

[0034] In this embodiment, the first drive mechanism 11 is configured in a manual mechanical drive mode to reduce the failure rate of the electric drive equipment. A first rotating rod 112 passes through the furnace shell 3, and a first operating handle 111 is connected to the first operating end outside the furnace shell 3. Exemplarily, the first operating handle 111 is configured as an operating lever, and the first operating handle 111 and the first rotating rod 112 are arranged perpendicularly to form an L-shaped structure. The first driving end of the first rotating rod 112 inside the furnace shell 3 is connected to a first cleaning component 12, and the first cleaning component 12 is arranged perpendicularly to the first rotating rod 112. That is, the first operating handle 111, the first rotating rod 112, and the first cleaning component 12 form a "Z"-shaped structure, meaning that the first operating handle 111 and the first cleaning component 12 are both perpendicular to the first rotating rod 112 and are parallel to each other. In use, swinging the first operating handle 111 causes the first rotating rod 112 to rotate, which in turn causes the first cleaning component 12 to swing and wipe the viewing lens 100. Furthermore, to ensure a vacuum environment inside the vacuum furnace, multiple sealing rings are spaced apart along the extension direction of the first rotating rod 112. Specifically, as shown... Figure 1 As shown, two sealing rings are provided, with their opposite sides embedded in the furnace shell and the first rotating rod 112. It is understood that the sealing rings can still provide a sealing effect when the first rotating rod 112 rotates horizontally.

[0035] In some embodiments, the second drive mechanism 21 includes a second operating handle 211 and a second rotating rod 212. The second rotating rod 212 has a second operating end and a second drive end. The second operating handle 211 is connected to the second operating end, and the second cleaning component 22 is connected to the second drive end. The second operating handle 211 is used to drive the second drive end to rotate outside the furnace shell 3.

[0036] In this embodiment, the second drive mechanism 21 and the first drive mechanism 11 are set in basically the same way. The difference is that in the embodiment where the second cleaning component 22 is set as an argon gas pipeline, the argon gas pipeline passes through the second rotating rod 212.

[0037] In some embodiments, the first driving mechanism 11 includes a first driving member and a second driving member, the first driving member being connected to the second driving member, the first driving member being used to drive the second driving member to move in a first direction toward the peephole lens 100, the first cleaning component 12 being connected to the second driving member, the second driving member being used to drive the first cleaning component 12 to move in a second direction toward the peephole lens 100, wherein the first direction and the second direction are perpendicular.

[0038] In this embodiment, the first driving mechanism 11 of this disclosure is used to drive the first cleaning component 12 to move. The first cleaning component 12 is a contact-type wiping cleaning component, and the first cleaning component 12 should more accurately clean and wipe the peephole lens 100. Therefore, the first driving mechanism 11 of this disclosure includes a first driving member and a second driving member. The first driving member is used to drive the second driving member to move in a first direction toward the peephole lens 100. The first cleaning component 12 is connected to the second driving member, and the second driving member is used to drive the first cleaning component 12 to move in a second direction toward the peephole lens 100, wherein the first direction and the second direction are perpendicular. For example, the first driving component is configured as a lead screw stepper motor. The first driving component can drive the second driving component to move radially within the viewing aperture lens 100, allowing the first cleaning component 12 to wipe within that range. The second driving component drives the first cleaning component 12 to move in a second direction along the viewing aperture lens 100, with the first and second directions perpendicular. That is, the second driving component drives the first cleaning component 12 to move along a path perpendicular to the movement range of the first driving component, i.e., along two mutually perpendicular radial directions of the viewing aperture lens 100. In this way, the first driving mechanism 11 ensures that the first cleaning component 12 can wipe the entire area of ​​the viewing aperture lens 100. In this embodiment, the first and second driving components are not limited to lead screw stepper motors; they can also be other linear drive mechanisms, such as telescopic cylinders.

[0039] In some embodiments, the first cleaning component 12 includes a base 121 and a cleaning element 122. The base 121 is connected to the first drive mechanism 11, and the cleaning element 122 is disposed on the base 121 and faces the viewing lens 100 to be cleaned. The stability of the cleaning element 122 is ensured by the placement of the base 121.

[0040] In some embodiments, a telescopic mechanism is also included, through which the cleaning member 122 is connected to the base 121. The telescopic mechanism is used to move the cleaning member 122 closer to or further away from the peephole lens 100 to be cleaned.

[0041] In this embodiment, the cleaning component 122 will experience wear and deformation after long-term use. To ensure the contact area and release force between the cleaning component 122 and the viewing lens 100, this disclosure provides that the cleaning component 122 is connected to the base 121 via a telescopic mechanism. Exemplarily, the telescopic mechanism can be one or more telescopic rods, telescopic blocks, etc. This disclosure specifically uses multiple telescopic rods to constitute the telescopic mechanism. For example, in an embodiment where the cleaning component 122 is a wiping cloth, multiple telescopic rods are arranged in an array on the cleaning component 122. Furthermore, the arrayed telescopic rods can be independently driven to ensure independent support at a severely worn location, thus ensuring the contact area between the cleaning component 122 and the viewing lens 100. Alternatively, the telescopic mechanism can be composed of multiple telescopic blocks, which divide the cleaning component 122 into multiple adjustment zones. The telescopic block in the zone where the cleaning component 122 is severely worn independently supports that zone, thereby achieving the above objective. Exemplarily, the telescopic mechanism can also be configured as a telescopic cylinder, a telescopic hydraulic cylinder, or an electric telescopic rod.

[0042] In some embodiments, the second cleaning component 22 includes a blowing pipe 221 and a shut-off valve 222. The blowing pipe 221 is connected to the second drive mechanism 21 and has a blowing medium inlet and a blowing medium outlet. The blowing medium inlet is located outside the furnace shell 3, the shut-off valve 222 is located at the blowing medium inlet, and the blowing medium outlet faces the viewing lens 100 to be cleaned.

[0043] In this embodiment, there is a blow-through pipe 221 and a shut-off valve 222, wherein the blow-through pipe 221 is configured as an argon gas pipe, and the shut-off valve 222 is used to close or open the blow-through pipe 221. Specifically, the shut-off valve 222 disclosed herein can be a ball valve.

[0044] In some embodiments, the blowing pipe 221 is provided with a length adjustment section 2211, which is located on the side of the blowing pipe 221 near the outlet of the blowing medium, and the length adjustment section 2211 is used to adjust the length of the blowing pipe 221.

[0045] In this embodiment, the length adjustment section 2211 is disposed on the side of the blow-through pipe 221 near the outlet of the blow-through medium, and the length adjustment section 2211 is used to adjust the length of the blow-through pipe 221. Specifically, the length adjustment section 2211 can be configured as a flexible metal connection woven into a tubular electric telescopic rod, and the length of the blow-through pipe 221 can be adjusted by extending and retracting the telescopic rod, thereby improving the blow-through cleaning effect of the second cleaning assembly 22 on the peephole lens 100.
