[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1:

[0019] like Figure 1 As shown, the furnace eye protection device includes a slide rail 1, a traveling trolley 2, a fireproof screen 3, an operating window 4, a support roller 5, and a height adjustment device 6.

[0020] A traveling trolley 2 is slidably connected to the bottom end of the slide rail 1. A vertically installed fireproof screen 3 is fixed to the bottom end of the traveling trolley 2. With the cooperation of the slide rail 1 and the traveling trolley 2, when the operator opens, blocks, or checks the furnace hole and its internal condition, the fireproof screen 3 is moved. The fireproof screen 3 blocks the silicon liquid splashed from the furnace hole to the surroundings. An operating window 4 is opened inside the fireproof screen 3. The operating window 4 is equipped with a horizontally installed support roller 5. By installing the support roller 5 in the protective device, the steel rod can be placed on the support roller 5. When the operator pushes and pulls the steel rod, the operator needs to reduce physical strength, save time, improve work efficiency, and ensure the safety and continuity of production. The two ends of the support roller 5 extend to the outside of the operating window 4 and are connected to the height adjustment device 6. According to the position of the furnace hole, the support roller 5 can be moved up and down along the operating window 4 through the height adjustment device 6. This ensures that the position of the steel rod and the furnace hole is relatively set during the operator's opening and blocking operations, reducing damage to the furnace hole and reducing labor.

[0021] The height adjusting device 6 comprises a fixed plate 6.1 and a telescopic device 6.2, the outer wall of the fireproof screen 3 on both sides of the operation window 4 is respectively fixed with a vertically arranged fixed plate 6.1, the fixed plate 6.1 is provided with a guide through slot 6.1.1 which is perpendicular to the plate surface of the fireproof screen 3, a supporting shaft 5.1 of a supporting roller 5 is arranged between the two guide through slots 6.1.1 and is in sliding connection with the guide through slot 6.1.1, the outer wall of the fireproof screen 3 is fixed with the telescopic device 6.2, the supporting shaft 5.1 of the supporting roller 5 reciprocates up and down along the guide through slot 6.1.1 through the telescopic device 6.2, the supporting roller 5 slides up and down along the guide through slot 6.1.1 through the cooperation of the telescopic device 6.2, since the furnace body has a large number of furnace eyes and the positions of the furnace eyes are different in height after long-term use, the position of the supporting roller 5 is adjusted according to the position of the furnace eye, so that the operation process is more flexible and the operation accuracy is higher.

[0022] The telescopic device 6.2 comprises a self-locking hand winch 6.2.1, a first guide wheel 6.2.2, a second guide wheel 6.2.3 and a third guide wheel 6.2.4 which are respectively fixed to the outer wall of the fireproof screen 3, the upper part of the two fixed plates 6.1 is respectively provided with the first guide wheel 6.2.2, the second guide wheel 6.2.3 is arranged directly above the operation window 4, the third guide wheel 6.2.4 is arranged on one side of the fireproof screen 3, the self-locking hand winch 6.2.1 is arranged below the third guide wheel 6.2.4, the two side ends of the supporting shaft 5.1 of the supporting roller 5 are respectively fixedly connected with one end of a second steel wire rope 6.2.6 through the first steel wire rope 6.2.5 which passes through the first guide wheel 6.2.2, the other end of the second steel wire rope 6.2.6 is fixedly connected with the self-locking hand winch 6.2.1 through the second guide wheel 6.2.3 and the third guide wheel 6.2.4, the first steel wire rope 6.2.5 and the second steel wire rope 6.2.6 are pulled by the self-locking hand winch 6.2.1 to drive the supporting roller 5 to move up and down along the guide through slot 6.1.1, the height of the supporting roller 5 is adjusted, the manpower is saved and the accuracy is high.

[0023] The specific operation process of the embodiment is as follows:

[0024] The two ends of the supporting shaft 5.1 of the supporting roller 5 are respectively arranged in the guide through slots 6.1.1 on the two sides, the guide through slots 6.1.1 limit the supporting shaft 5.1 of the supporting roller 5 and only allow the supporting shaft 5.1 of the supporting roller 5 to move up and down along the guide through slot 6.1.1;

[0025] When the operator opens, closes, or inspects the furnace opening and its internal condition, the fireproof screen 3 is moved to the furnace opening so that the operation window 4 of the fireproof screen 3 corresponds to the furnace opening. According to the position of the furnace opening, the operator rotates the self-locking hand-cranked winch 6.2.1 and uses the cooperation of the first wire rope 6.2.5, the second wire rope 6.2.6, the first guide wheel 6.2.2, the second guide wheel 6.2.3, and the third guide wheel 6.2.4 to pull the roller 5 up and down along the guide groove 6.1.1, moving the roller 5 to be flush with the bottom of the furnace opening.

[0026] Afterwards, the operator can place the steel rod on the support roller 5. The rotation of the support roller 5, in conjunction with the movement of the steel rod, reduces the friction between the steel rod and the operating window 4, thereby reducing the labor intensity of the operator and improving work efficiency.

[0027] After the operator finishes their work, they remove the steel rod from the furnace hole and move the fireproof screen 3 to the next furnace hole location.

[0028] Example 2:

[0029] like Figures 2-3 As shown, the difference between this embodiment and Embodiment 1 lies in the height adjustment device 6. In this embodiment, the height adjustment device 6 includes a U-shaped mounting base 6.3. Several sets of opposing U-shaped mounting bases 6.3 are fixed to the outer walls of the fireproof screens 3 on both sides of the operating window 4. A roller 5 is provided between one set of U-shaped mounting bases 6.3. The end of the support shaft 5.1 of the roller 5 is placed inside the U-shaped mounting base 6.3. According to the position of the furnace hole, the operator moves the roller 5 to the set of U-shaped mounting bases 6.3 at the corresponding furnace hole position. With the cooperation of the U-shaped mounting bases 6.3, the position of the roller 5 is adjusted. When the operator opens, blocks, or checks the furnace hole and its internal condition, the steel rod tower is set on the upper part of the roller 5 with the cooperation of the roller 5. During the back and forth movement of the steel rod, the roller 5 rotates, saving manpower and labor intensity, and improving work efficiency.

[0030] The specific operation process of this embodiment;

[0031] When operators open, close, or inspect the furnace bore and its internal condition, they adjust the position of the support roller 5 according to the location of the bore, ensuring that both ends of the support roller 5 rest within the corresponding U-shaped mounting base 6.3. Then, the fireproof screen 3 is moved to the furnace bore, aligning its operating window 4 with the bore. The operator can then place a steel rod on the support roller 5. The rotation of the support roller 5, combined with the movement of the steel rod, reduces friction between the steel rod and the operating window 4, lowering the operator's workload and improving work efficiency. After finishing their work, the operator removes the steel rod from the furnace bore and moves the fireproof screen 3 to the next bore location.
