Description

Technical Field

[0001] This utility model relates to the field of cold slag machine rotor technology, and more specifically, to a quick-change structure for wear-resistant liner plates of cold slag machine rotors. Background Technology

[0002] In the current technological context, slag coolers, as important industrial equipment, are widely used in high-energy-consuming fields such as thermal power plants and steel mills. The main function of a slag cooler is to separate unburned coal particles from high-temperature slag, thereby reducing the ash content of the slag and improving energy utilization efficiency.

[0003] The slag cooler rotor is a crucial component in industrial boiler systems. Its primary function is to collect high-temperature slag particles from the furnace bottom and transport them out, maintaining optimal operating temperature and cleanliness within the furnace. Slag cooler rotors are typically designed to withstand high temperatures and corrosion, and possess excellent wear resistance to adapt to the harsh conditions of the furnace bottom environment. To enhance wear resistance, wear-resistant liners are usually installed at the rotor's edges. However, during prolonged operation, these liners suffer severe wear due to high temperatures and abrasion, directly impacting the reliability and efficiency of the slag cooler.

[0004] To address this issue, many research institutions and companies have proposed various quick-replacement structural solutions for wear-resistant liners on cold slag machine rotors. Traditional replacement methods, due to their complex structure and inconvenient operation, often fail to achieve timely replacement, leading to excessive equipment downtime and increased maintenance costs. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a quick-change structure for the wear-resistant liner of the rotor of a cold slag machine, which has the advantage of quick replacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-change structure for a wear-resistant liner of a cold slag machine rotor, comprising an upper plate and a lower plate, both having a semi-circular cross-sectional shape. The bottom of the upper plate and the top of the lower plate are movably connected. The upper plate and the lower plate are respectively fitted onto the upper and lower halves of the cold slag machine rotor. One side of the upper and lower plates is provided with a plurality of first upper connecting holes and first lower connecting holes, and the other side of the upper and lower plates is provided with a plurality of second upper connecting holes and second lower connecting holes. The first upper connecting holes and first lower connecting holes are movably connected to a first connecting shaft, which is circumferentially distributed on the side of a first connecting ring. The first connecting ring is slidably connected to the outer surface of the cold slag machine rotor. The second upper connecting holes and second lower connecting holes are movably connected to a second connecting shaft, which is circumferentially distributed on the side of a second connecting ring. The second connecting ring is slidably connected to the outer surface of the cold slag machine rotor.

[0007] As a preferred embodiment of this utility model, a first limiting cylinder is threadedly connected to the outer surface of the slag cooler rotor on one side of the first connecting ring, and a second limiting cylinder is threadedly connected to the outer surface of the slag cooler rotor on one side of the second connecting ring.

[0008] As a preferred embodiment of this utility model, the bottom of the upper plate is provided with multiple fixed shafts, and the top of the lower plate is provided with a fixing groove that cooperates with the fixed shafts.

[0009] As a preferred embodiment of this utility model, a protective plate is provided on the top of the lower plate outside the fixing groove, a protective groove that cooperates with the protective plate is provided on the bottom of the upper plate, and the fixing shaft is located inside the protective groove.

[0010] As a preferred embodiment of this utility model, an upper protective pad and a lower protective pad are bonded to the inner surfaces of the upper plate and the lower plate.

[0011] As a preferred embodiment of this utility model, both sides of the upper plate are provided with lifting grooves, and the lifting grooves are rectangular in shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a connectable upper plate and lower plate, protects the rotor of the slag cooler by surrounding it. Furthermore, the upper and lower plates are slidably connected by a first connecting ring and a second connecting ring on their respective sides, thus limiting and fixing the upper and lower plates and improving their stability when placed. With this structure, replacement is possible simply by moving the first and second connecting rings outward from the upper plate, followed by manual disassembly of the damaged upper and lower plates, greatly improving the convenience of replacement.

[0014] 2. This utility model, by setting up a first limiting cylinder and a second limiting cylinder with threaded connection, after the first connecting ring and the second connecting ring are connected to the corresponding upper plate and lower plate side, respectively, abuts against the first connecting ring and the second connecting ring, thereby achieving the limitation of the first connecting ring and the second connecting ring.

[0019] 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.

[0020] like Figures 1 to 3 As shown, this utility model provides a quick-change structure for wear-resistant liners on a cold slag machine rotor, including an upper plate 2 and a lower plate 3. Both the upper plate 2 and the lower plate 3 have semi-circular cross-sectional shapes. The bottom of the upper plate 2 and the top of the lower plate 3 are movably connected. The upper plate 2 and the lower plate 3 are respectively fitted onto the upper and lower halves of the cold slag machine rotor 1. One side of the upper plate 2 and the lower plate 3 is provided with multiple first upper connecting holes 14 and first lower connecting holes 15, and the other side of the upper plate 2 and the lower plate 3 is provided with multiple second upper connecting holes 14 and 15. The connecting hole 10 and the second lower connecting hole 11, the first upper connecting hole 14 and the first lower connecting hole 15 are all movably connected to the first connecting shaft 5. The first connecting shaft 5 is circumferentially distributed on the side of the first connecting ring 4. The first connecting ring 4 is slidably connected to the outer surface of the slag cooler rotor 1. The second upper connecting hole 10 and the second lower connecting hole 11 are all movably connected to the second connecting shaft 7. The second connecting shaft 7 is circumferentially distributed on the side of the second connecting ring 6. The second connecting ring 6 is slidably connected to the outer surface of the slag cooler rotor 1.

[0021] By setting up a splicable upper plate 2 and lower plate 3, during installation, the upper plate 2 and lower plate 3 can be respectively fitted onto the upper and lower halves of the slag cooler rotor 1. After the fitting is completed, the upper plate 2 and lower plate 3 are connected to each other, so that the slag cooler rotor 1 is located between the upper plate 2 and lower plate 3. The upper plate 2 and lower plate 3 surround and protect the slag cooler rotor 1. The first connecting ring 4 and the second connecting ring 6 are slidably connected to the two sides of the upper plate 2 and lower plate 3 respectively, so as to limit and fix the upper plate 2 and lower plate 3, thereby improving the stability of the upper plate 2 and lower plate 3 when placed. With the above structure, when replacing, it is only necessary to move the first connecting ring 4 and the second connecting ring 6 to the outside of the upper plate 2, and then manually disassemble the damaged upper plate 2 and lower plate 3, which improves the convenience of replacement.

[0022] The outer surface of the slag cooler rotor 1 on one side of the first connecting ring 4 is threaded with a first limiting cylinder 8, and the outer surface of the slag cooler rotor 1 on one side of the second connecting ring 6 is threaded with a second limiting cylinder 9.

[0023] By setting the first limiting cylinder 8 and the second limiting cylinder 9 with threaded connection, after the first connecting ring 4 and the second connecting ring 6 are connected to the sides of the corresponding upper plate 2 and lower plate 3, they respectively abut against the first connecting ring 4 and the second connecting ring 6, thereby achieving the limitation of the first connecting ring 4 and the second connecting ring 6.

[0024] The upper plate 2 has multiple fixed shafts 16 at its bottom, and the lower plate 3 has a fixed groove 17 at its top that cooperates with the fixed shafts 16.

[0025] By setting a fixed shaft 16 and a fixed groove 17, the stability of the connection between the upper plate 2 and the lower plate 3 is improved through the connection between them.

[0026] The lower plate 3 on the outside of the fixing groove 17 is provided with a protective plate 19 on its top, and the upper plate 2 is provided with a protective groove 18 that cooperates with the protective plate 19 on its bottom. The fixing shaft 16 is located inside the protective groove 18.

[0027] By setting up the protective groove 18 and the protective plate 19, the connection between the upper plate 2 and the lower plate 3 can be protected to prevent foreign objects from entering the connection and causing damage to the connection, thus affecting the stability of the connection.

[0028] The upper protective pad 12 and the lower protective pad 13 are bonded to the inner surfaces of the upper plate 2 and the lower plate 3.

[0029] By setting the upper protective pad 12 and the lower protective pad 13, external forces can be buffered, thereby improving the protective performance of the upper plate 2 and the lower plate 3.

[0030] The upper plate 2 has lifting grooves 20 on both sides, and the lifting grooves 20 are rectangular in shape.

[0031] By setting a rectangular lifting groove 20, it is easy to move the upper plate 2 through the lifting groove 20 during replacement, thereby realizing the separation of the upper plate 2 and the lower plate 3.

[0032] Working principle and usage process of this utility model:

[0033] By setting up a splicable upper plate 2 and lower plate 3, during installation, the upper plate 2 and lower plate 3 can be respectively fitted onto the upper and lower halves of the slag cooler rotor 1. After the fitting is completed, the upper plate 2 and lower plate 3 are connected to each other, so that the slag cooler rotor 1 is located between the upper plate 2 and lower plate 3. The upper plate 2 and lower plate 3 surround and protect the slag cooler rotor 1. The first connecting ring 4 and the second connecting ring 6 are slidably connected to the two sides of the upper plate 2 and lower plate 3 respectively, so as to limit and fix the upper plate 2 and lower plate 3, thereby improving the stability of the upper plate 2 and lower plate 3 when placed. With the above structure, when replacing, it is only necessary to move the first connecting ring 4 and the second connecting ring 6 to the outside of the upper plate 2, and then manually disassemble the damaged upper plate 2 and lower plate 3, which improves the convenience of replacement.
