Description

Technical Field

[0001] This utility model relates to the field of industrial silicon furnace technology, specifically to a safety protection device for industrial silicon furnace tapping. Background Technology

[0002] Industrial silicon is produced by a reduction reaction of molten silicon, carbonaceous reducing agent, and wood chips in an industrial silicon furnace under high-temperature conditions. The resulting liquid molten silicon accumulates at the bottom of the furnace. The tapping process is one of the important steps in the industrial silicon smelting process. It involves using a burn-through device to open the furnace opening (silicon tapping port) and discharge the high-temperature molten silicon produced from the furnace bottom through the tapping port (furnace opening) outside the furnace.

[0003] In China, most industrial silicon smelting is carried out manually. The process of unloading the furnace includes opening the furnace opening, burning the opening to remove slag, using wooden poles to remove slag, and plugging the opening. Currently, during the operations of using wooden poles to remove slag, plugging the opening, and blowing oxygen to open the opening, personnel need to stand directly in front of the furnace opening. A large amount of high-temperature molten silicon and sparks will splash from the furnace opening. These high-temperature substances will penetrate into the work area and come into contact with the workers, who are often burned. Utility Model Content

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1 As shown, this utility model discloses a safety protection device for industrial silicon furnace tapping, including a slide rail arranged in an arc around the industrial silicon furnace, a sliding seat slidably mounted on the slide rail, and a protective plate 1 mounted on the sliding seat. The industrial silicon furnace is a rotary electric furnace, and the rotation trajectory of the furnace opening is located on the inner arc side of the slide rail and on the side of the protective plate 1. The operator can adjust the position of the protective plate 1 by sliding the sliding seat on the slide rail, so that the protective plate 1 blocks the outside of the furnace opening.

[0032] The protective plate 1 is provided with an observation port, and the protective plate 1 below the observation port is provided with an operating port. Both the observation port and the operating port are rectangular.

[0033] A support frame 2 is provided on the protective plate 1 at the edge of the observation port. The support frame 2 is set along the two sides and the bottom edge of the observation port, and the top side of the support frame 2 is the opening side.

[0034] Specifically, the support frame 2 includes a horizontally arranged bottom section, which is arranged along the bottom edge of the observation port and the top surface of the bottom section is not higher than the bottom edge of the observation port. The bottom section is connected to vertically arranged side sections at both ends. The side sections are arranged along the two sides of the observation port and the inner sidewalls of the two side sections that are close to each other do not exceed the corresponding side edge of the observation port. That is, the two side sections are symmetrically arranged and the distance between the two side sections is not less than the distance between the two sides of the observation port.

[0035] The inner wall of the support frame 2 is provided with an inner guide rail and an outer guide rail. Both the inner guide rail and the outer guide rail are opened along the inner wall of the support frame 2 (the side wall of the support frame 2 at the edge of the observation port). The inner guide rail and the outer guide rail pass through the top of both sides of the support frame 2. The inner guide rail is located on the side of the inner wall of the support frame 2 closer to the observation port.

[0036] A first inner observation plate 5 is slidably provided in the inner guide rail, and a first outer observation plate 4 is slidably provided in the outer guide rail. The first inner observation plate 5 and the first outer observation plate 4 are slid vertically downward along the inner and outer guide rails at the top opening of the side section of the support frame 2 to block the observation port. Since the top surface of the bottom section of the support frame 2 is not higher than the bottom edge of the observation port, and the inner sidewalls of the two side sections that are close to each other do not exceed the corresponding side edge of the observation port, the first inner observation plate 5 and the first outer observation plate 4 will cover the entire observation port.

[0037] Both the top edges of the first inner observation plate 5 and the first outer observation plate 4 are provided with enlarged ends that are easy for personnel to operate. The cross-section of the enlarged end is inverted triangular, and its cone part is in contact with the top edge of the first inner observation plate 5 or the first outer observation plate 4.

[0038] The protective plate 1 at the operating port is provided with a support plate 3. The support plate 3 is horizontally set and covers the entire operating port. Four sliding grooves are provided in the horizontal direction inside the support plate 3. The four sliding grooves are parallel to each other and equally spaced. The four sliding grooves pass through the two sides of the support plate 3 respectively.

[0039] The support plate 3 has a slot 6 that corresponds to the operation port. The length and width of the slot 6 are not less than the length and width of the operation port, so that the operation port can be completely inside the slot 6.

[0040] A second inner observation plate 8 is slidably installed in each of the two inner grooves near the operation port, and a second outer observation plate 9 is slidably installed in each of the two outer grooves away from the operation port.

[0041] The bottom of both the second inner observation plate 8 and the second outer observation plate 9 is provided with two support plates, and rollers 10 are rotatably mounted on the support plates. The rolling of the rollers 10 causes the second inner observation plate 8 and the second outer observation plate 9 to slide within the groove.

[0042] Each of the support plates 3 on both sides of the slot 6 has a screw hole 7 on its top. The screw hole 7 covers four sliding grooves. The screw hole 7 is threaded with an adjusting bolt (not shown in the figure) that mates with the second inner observation plate 8 and the second outer observation plate 9. Loosening the adjusting bolt allows the second inner observation plate 8 and the second outer observation plate 9 to slide in the sliding groove. Tightening the adjusting bolt fixes the second inner observation plate 8 and the second outer observation plate 9 in the sliding groove.

[0043] The two second inner observation plates 8 and the two second outer observation plates 9 slide towards each other from both sides. The bottom of the side walls of the two second inner observation plates 8 and the bottom of the side walls of the two second outer observation plates 9 are provided with operation notches 11. The operation notches 11 are fan-shaped and the outer arc side faces away from the slot 6.

[0044] The first inner observation plate 5 and the second inner observation plate 8 are made of quartz glass, while the first outer observation plate 4 and the second outer observation plate 9 are made of dark-colored explosion-proof tempered glass. The thickness of the quartz glass and the dark-colored explosion-proof tempered glass is 10-20mm. The quartz glass can withstand temperatures of 1100~1200 degrees Celsius for extended periods, effectively resisting splashes of molten metal and preventing burns. The dark-colored explosion-proof tempered glass reduces heat radiation damage while ensuring a clear view of the silicon outlet.

[0045] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
