[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 The utility model provides a technical solution: a fireproof ring structure of an electric arc furnace that is easy to disassemble, including a pressure ring 1, an annular groove 2, a baffle 3, a fireproof baffle 4, a handle 5, a clamping plate 6, a tooth block 7, a limit block 8, a connecting plate 9, a slider 10, a rotating plate 11, and a limit plate 12.

[0031] Example 1

[0032] The fireproof ring structure of the ore-fired furnace that is easy to disassemble is provided with a limiting structure, and the limiting block 8 on the lower surface of the connecting plate 9 limits the tooth block 7 through the limiting plate 12, specifically:

[0033] The handle 5 is connected to a limiting structure, and the limiting structure can drive the limiting plate 12 to move by rotating the rotating plate 11 so that the limiting block 8 on the lower surface of the connecting plate 9 limits and engages the card plate 6. The limiting structure includes a limiting block 8, which slides through the upper surface of the baffle 3, and the upper surface of the limiting block 8 is fixedly installed with a connecting plate 9, and a slider 10 is fixedly installed at one end of the connecting plate 9, and the slider 10 is slidably installed on the side surface of the baffle 3. The outer surface of the handle 5 is rotatably connected with the rotating plate 11, and the outer surface of the rotating plate 11 is fixedly installed with a limiting plate 12, and the lower surface of the limiting plate 12 contacts with the upper surface of the connecting plate 9. A plurality of limiting blocks 8 are arranged at equal intervals, and the interval between the limiting blocks 8 corresponds to the gap between the tooth blocks 7, and three limiting plates 12 are arranged at equal intervals.

[0034] The fireproof ring structure of the ore-fired furnace which is easy to disassemble is as follows: Figure 1 As shown, firstly, the rotating plate 11 connected to the outer surface of the handle 5 is rotated, so that the rotating plate 11 drives the limiting plate 12 to rotate, and the lower surface of the rotating plate 11 will lose contact with the upper surface of the connecting plate 9. The rotating plate 11 is provided with three, so that the rotating plate 11 is rotated to the upper part between the gaps of the three baffles 3, so that the connecting plate 9 loses the pressing of the rotating plate 11. At this time, the state of the rotating plate 11 and the connecting plate 9 is as shown in FIG. Figure 4 As shown, in the groove of the baffle 3, the lower ends of multiple limit blocks 8 are located between the tooth blocks 7, and the tooth blocks 7 are engaged by the limit blocks 8, so that the card plate 6 is limited, and the connecting plate 9 is pressed together by the limit plate 12, so that the limit blocks 8 and the tooth blocks 7 can remain engaged, and the fireproof baffle ring 4 can be engaged to prevent the fireproof baffle ring 4 from rotating, so that the installation of the fireproof baffle ring 4 is more stable and cannot rotate. At this time, the connecting plate 9 is slid upward through the slider 10, so that the connecting plate 9 drives the limit blocks 8 to slide upward on the upper surface of the baffle 3, which will cause the limit blocks 8 to lose engagement with the tooth blocks 7 set on the upper surface of the card plate 6, facilitating the subsequent disassembly of the fireproof baffle ring 4.

[0035] Example 2

[0036] The fireproof ring structure of the ore-fired furnace that is easy to disassemble is provided with a clamping structure, and the clamping plate 6 is clamped with the baffle 3 by rotating the fireproof baffle ring 4, and the operation is simple, specifically:

[0037] An annular groove 2 is provided on the upper surface of the pressure ring 1, and also includes a baffle 3, which is fixedly installed on the inner wall surface of the annular groove 2, and the annular groove 2 is connected with a clamping structure, and the clamping structure can make the clamping plate 6 and the baffle 3 clamped by rotating the fireproof baffle ring 4, and the clamping structure includes the fireproof baffle ring 4, and a handle 5 is fixedly installed on the upper surface of the fireproof baffle ring 4, and a clamping plate 6 is fixedly installed on the outer surface of the fireproof baffle ring 4, and the clamping plate 6 is set as a fan-shaped structure, and the clamping plate 6 corresponds to the baffle 3, and the upper surface of the clamping plate 6 is evenly spaced. Tooth blocks 7 are arranged at equal intervals, and there are only three equal intervals of the clamping plates 6, and a groove is arranged between the baffle 3 and the annular groove 2, and the lower end of the baffle 3 is fixedly connected to the upper surface of the annular groove 2;

[0038] Furthermore, after the tooth block 7 loses its engagement with the tooth block 7, the card plate 6 can be rotated. At this time, the handle 5 installed on the upper surface of the fire baffle ring 4 is rotated, so that the handle 5 drives the fire baffle ring 4 to rotate. Since the card plate 6 is fixedly installed on the outer surface of the fire baffle ring 4, the fire baffle ring 4 will drive the card plate 6 to rotate on the upper surface of the annular groove 2, so that the three card plates 6 move outward from between the grooves of the three baffle plates 3, and then the three card plates 6 will be respectively located between the gaps of the three baffle plates 3. Then the handle 5 is lifted upward to remove the fire baffle ring 4, avoiding the use of bolts, making disassembly faster and facilitating regular maintenance of the pressure ring 1.

[0039] Working principle: When using the easily disassembled fireproof ring structure of the electric arc furnace, a limiting structure is set. After the connecting plate 9 loses its engagement by rotating the limiting plate 12, it is convenient to control the limiting block 8 on the lower surface to lose its engagement with the tooth block 7. The engaging structure card plate 6 is rotated to engage with the baffle 3, which enables quick disassembly and assembly, thereby increasing the overall practicality.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
