Description

Technical Field

[0001] This invention belongs to the technical field of welding auxiliary equipment, specifically relating to a flashing window device for welding tanks in smelting furnaces. Background Technology

[0002] Existing welding tanks and other tank-like equipment in smelting furnaces are typically equipped with observation windows to allow operators to observe the internal workings. Traditionally, these observation windows are simply transparent glass covering the window. However, during welding operations, a large amount of high-temperature metal spatter is generated. This spatter easily splashes and adheres to the observation glass, not only obstructing the view and affecting observation quality, but also causing burns, adhesion, or even cracks to the glass surface. Frequent replacement of damaged observation glass increases maintenance costs and impacts production efficiency. Therefore, it is necessary to improve the existing observation window structure. Summary of the Invention

[0003] The technical problem solved by the present invention: The purpose of the present invention is to provide a flash window device for the welding tank of a smelting furnace, so as to solve the problem that the observation window glass is easily damaged by welding spatter in the prior art, so as to not only achieve clear observation of the welding process, but also effectively protect the observation glass.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A flash window device for welding tanks in smelting furnaces includes a disc-shaped flash window mounting housing, a flash window rotating plate, an observation glass, and a driving mechanism. The disc-shaped flash window mounting housing includes: a window mounting plate, a window fixing plate, and an annular connecting plate. The window mounting plate is provided with an outer observation port, the window fixing plate is provided with an inner observation port, and the annular connecting plate is used to connect the window mounting plate and the window fixing plate together, and the three together form an inner cavity. The flash window rotating plate is rotatably disposed in the inner cavity, and the flash window rotating plate has multiple flashing slits; The observation glass cover is provided on the outer observation port; The driving mechanism is located on the outside of the window mounting plate and is connected to the flash window rotating plate for driving the flash window rotating plate to rotate.

[0005] As a further limitation of the above scheme, the plurality of flashing slits are arranged radially and evenly around the circumference of the flashing window rotating plate.

[0006] Further defining the above solution, the drive mechanism includes: a shaft mounting base, a shaft, a motor, and a chain drive mechanism; The shaft mounting base is fixed to the outer center of the window mounting plate; The shaft is rotatably supported in the shaft mounting base by a bearing, and its inner end passes through the window mounting plate and is fixedly connected to the center of the flashing window rotating plate. The motor is fixed to the outside of the window mounting plate; The chain drive mechanism connects the motor output shaft to the outer end of the shaft.

[0007] Further defining the above scheme, the chain drive mechanism includes: a driving sprocket, a driven sprocket, and a chain; The drive sprocket is mounted on the motor output shaft; The passive sprocket is disposed at the outer end of the shaft; The chain connects the driving sprocket and the driven sprocket.

[0008] Further defining the above solution, a motor mounting base is provided on the outer side of the window mounting plate, and the motor is mounted on the motor mounting base via a motor adjustment plate. The motor mounting base or the motor adjustment plate is provided with an elongated adjustment hole for adjusting the installation position of the motor, which facilitates the adjustment of the chain tension.

[0009] Further defining the above solution, the motor mounting base is composed of two L-shaped plates arranged opposite each other, and the motor adjusting plate is connected to the motor mounting base through a connector passing through the elongated adjusting hole.

[0010] As a further limitation of the above scheme, the observation glass is fixed to the window mounting plate by a glass pressure plate.

[0011] Advantages of this invention compared to existing technologies: 1. This solution protects the glass: By using a high-speed rotating flash window plate to block welding spatter, the risk of damage to the observation glass from spatter is greatly reduced, extending the service life of the glass and reducing maintenance costs; 2. Dynamic observation in this solution: Utilizing the persistence of vision effect, dynamic observation is achieved through a high-speed rotating slit, which ensures both the clarity of observation and the protection of the glass. 3. This solution has a compact structure: the drive mechanism, rotating plate, glass and other components are integrated into a disc-shaped housing, resulting in a compact overall structure, easy installation and minimal external space occupation; 4. This solution is easy to adjust: the tension of the chain can be easily adjusted by the cooperation of the motor adjustment plate and the elongated hole, ensuring the stability and reliability of the transmission; 5. This solution has a wide range of applications: This device is not only suitable for welding tanks, but can also be applied to other similar equipment that requires observation of the internal conditions and is subject to the risk of damage from splashes.

[0017] Please see Figure 1-11 The embodiments of the present invention are described in detail below.

[0018] like Figure 1-2 As shown, this embodiment provides a flash window device for a welding tank in a smelting furnace, mainly comprising a disc-shaped flash window mounting shell. This shell is formed by welding or integrally molding a circular window mounting plate 1, a circular window fixing plate 2, and an annular connecting plate 3 connecting their outer edges, creating a closed annular inner cavity. Figure 4-5 As shown, the window mounting plate 1 and the window fixing plate 2 are respectively provided with an outer observation port 1-1 and an inner observation port 2-1 at an eccentric position. During installation, these two observation ports need to be aligned with the observation holes on the welding tank body.

[0019] An observation glass 14 is installed at the outer observation port 1-1. The observation glass 14 is fastened to the outer surface of the window mounting plate 1 with screws by a glass pressure plate 15 around its perimeter. Figure 6-7 As shown, this is to achieve sealing and fixation.

[0020] A circular window rotating plate 4 is installed in the cavity between the window mounting plate 1 and the window fixing plate 2. Figure 3 As shown, the rotating plate 4 of the flash window has multiple radially and evenly distributed flashing slits 4-1, making the field of view more uniform.

[0021] A shaft mounting base 5 is fixedly installed at the center of the outer side of the window mounting plate 1. A shaft 6 is rotatably supported inside the shaft mounting base 5 by two bearings 7. One end (inner end) of the shaft 6 passes through a shaft hole opened in the center of the window mounting plate 1, extends into the inner cavity, and is fixed to the center of the flashing window rotating plate 4 by key connection or welding. The other end (outer end) of the shaft 6 extends out of the shaft mounting base 5.

[0022] A motor 10 is fixed to the outside of the window mounting plate 1 via a motor mounting bracket 8. For example... Figure 8-10As shown, in this embodiment, the motor mounting base 8 is composed of two parallel, spaced-apart L-shaped steel plates, each with elongated adjustment holes. A motor adjustment plate 9 is mounted on the two L-shaped plates via bolts passing through these elongated holes. The motor 10 is fixedly mounted on the motor adjustment plate 9. A drive sprocket 11 is mounted on the output shaft of the motor 10, and a driven sprocket 12 is mounted on the outer end of the shaft 6. The drive sprocket 11 and the driven sprocket 12 are connected by a chain 13.

[0023] By loosening the bolts on the motor adjusting plate 9, the motor adjusting plate 9 can be moved back and forth under the guidance of the elongated hole, thereby changing the position of the motor 10 and achieving precise adjustment of the tension of the chain 13. After adjustment, simply tighten the bolts again.

[0024] At work, such as Figure 11 As shown, the motor 10 is started, driving the drive sprocket 11 to rotate. This drives the shaft 6 to rotate at high speed via the chain 13 and the driven sprocket 12, which in turn drives the flashing window rotating plate 4 to rotate at high speed within the inner cavity (up to 2000 rpm or more). Due to the persistence of vision, when the flashing window rotating plate 4 rotates at high speed, the multiple flashing slits 4-1 on it form a dynamic and continuous observation surface. The operator can clearly observe the inside of the welding box through the observation glass 14 on the outer observation port 1-1 and through this dynamic and continuous observation surface. Simultaneously, the high-speed rotating flashing window rotating plate 4 itself constitutes a dynamic protective barrier. Welding spatter impacting the rotating plate is deflected, preventing it from directly splashing onto the observation glass 14, thus effectively protecting the observation glass 14.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
