Description

Technical Field

[0001] This utility model specifically relates to a rotary kiln graphite block sealing device, belonging to the technical field of smelting equipment. Background Technology

[0002] Rotary kilns are an important production equipment widely used in industries such as ceramics, glass, and metallurgy. Their main function is to change the physical and chemical properties of materials through high-temperature firing. During the operation of a rotary kiln, the sealing device is one of the key components to ensure the efficient operation of the system. Rotary kilns usually use graphite blocks as sealing materials because they have good wear resistance and high-temperature resistance.

[0003] During the operation of a rotary kiln, traditional graphite block sealing devices, when used for extended periods in the high-temperature zone at the kiln tail, experience accelerated oxidation of graphite due to the high-temperature environment. This leads to a decrease in graphite strength, resulting in the graphite blocks cracking and falling off. This severely affects the sealing performance and service life of the equipment. Traditional axial graphite sealing designs are unable to cope with the radial runout of the kiln body and thermal deformation caused by temperature changes. This causes the graphite sealing blocks to float during the rotation of the kiln body, increasing the risk of leakage at the joints of the graphite blocks. This problem is particularly prominent in the high-temperature zone, which not only reduces the working efficiency of the kiln but also has an adverse impact on the production environment.

[0004] To solve the above technical problems, a rotary kiln graphite block sealing device is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a rotary kiln graphite block sealing device to prevent leakage at the joints when the graphite blocks float, and to shield and protect the graphite blocks and slow down oxidation.

[0006] A rotary kiln graphite block sealing device includes a main body and a limiting mechanism. The main body includes an annular support and graphite blocks. Y-shaped limiting members are fixedly connected to the outer side of the annular support at equal intervals. The graphite blocks are arranged in an annular array on the outer side of the annular support, and the graphite blocks are engaged with the Y-shaped limiting members.

[0007] The limiting mechanism includes a limiting ring and an elastic element. The limiting ring is sleeved on the outside of the graphite block. Inside the limiting ring, on the side near the Y-shaped limiting element, there are integrally formed abutments distributed at equal intervals. The elastic element is symmetrically fixedly connected to both sides of the abutments. The elastic element and the abutments engage with the Y-shaped limiting element.

[0008] Furthermore, a fixing plate is provided on one side of the annular bracket.

[0009] Furthermore, heat-conducting rods are equidistantly distributed on one side of the fixed plate, first insertion holes are equidistantly distributed inside the annular bracket, and second insertion holes are provided inside the graphite block. The heat-conducting rods pass through the second insertion hole and the first insertion hole in sequence.

[0010] Furthermore, a copper wire mesh is fixedly connected inside the graphite block.

[0011] Furthermore, a groove is provided on one side of the graphite block, and protrusions are integrally formed and distributed at equal intervals on one side of the annular bracket, with the protrusions engaging with the groove.

[0012] Furthermore, both sides of the graphite block and the Y-shaped limiting member are integrally formed with male and female openings, the female opening of the Y-shaped limiting member engaging with the female opening of the graphite block, and the female opening of the Y-shaped limiting member engaging with the male opening of the graphite block. Beneficial effects

[0013] This invention uses a Y-shaped limiting component in conjunction with a ring bracket to limit the installation of graphite blocks. When the graphite block floats due to radial runout, it will squeeze the upper part of the Y-shaped limiting component, causing it to contract inward and compress the elastic component, thus buffering the graphite block. At the same time, the elastic component is in close contact with the Y-shaped limiting component to prevent leakage at the joint caused by the floating graphite block. The limiting ring, together with the fixing plate, shields and protects the graphite block, preventing long-term exposure that could lead to accelerated oxidation. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-6 As shown, a rotary kiln graphite block sealing device consists of a main body mechanism 10 and a limiting mechanism 20.

[0023] The main structure 10 includes a ring support 11 and graphite blocks 12. Y-shaped limiting members 13 are fixedly connected to the outer side of the ring support 11 at equal intervals. The Y-shaped limiting members 13 are made of elastic metal and can undergo small deformation. The graphite blocks 12 are arranged in a ring array on the outer side of the ring support 11 and are engaged with the Y-shaped limiting members 13.

[0024] As a technical optimization of this utility model, in order to facilitate the installation and fixing of the graphite block 12, a groove 15 is provided on one side of the graphite block 12, and protrusions 14 are integrally formed and distributed at equal intervals on one side of the annular bracket 11. The protrusions 14 engage with the groove 15. Both sides of the graphite block 12 and the Y-shaped limiting member 13 are integrally formed with male and female openings. The female opening of the Y-shaped limiting member 13 engages with the female opening of the graphite block 12.

[0025] As a technical optimization of this utility model, in order to enhance the flexural strength of the graphite block 12, a copper wire mesh 18 is fixedly connected inside the graphite block 12.

[0026] The limiting mechanism 20 includes a limiting ring 21 and an elastic element 23. The limiting ring 21 is sleeved on the outside of the graphite block 12. Inside the limiting ring 21, on the side near the Y-shaped limiting element 13, there are integrally formed abutments 22 distributed at equal intervals. The elastic element 23 is symmetrically fixedly connected to both sides of the abutment 22. The elastic element 23 and the abutment 22 are engaged with the Y-shaped limiting element 13.

[0027] As a technical optimization of this utility model, in order to shield and protect the graphite block 12, a fixing plate 24 is provided on one side of the annular bracket 11, and heat-conducting rods 25 are equidistantly distributed on one side of the fixing plate 24. A first insertion hole 16 is equidistantly distributed inside the annular bracket 11, and a second insertion hole 17 is provided inside the graphite block 12. The heat-conducting rods 25 pass through the second insertion hole 17 and the first insertion hole 16 in sequence, and the heat-conducting rods 25 evenly transfer the temperature to each graphite block 12, preventing local heat accumulation from affecting the normal use of the graphite block 12 in that area.

[0028] Working principle: The annular bracket 11 is fitted onto the kiln head section cylinder, and graphite blocks 12 are installed sequentially. Simultaneously, the graphite blocks 12 engage with the Y-shaped limiting member 13, and the side of the graphite blocks 12 with the groove 15 engages with the protrusion 14 of the annular bracket 11. After all graphite blocks 12 are installed, the limiting ring 21 is fitted onto the outside, so that the abutment 22 inside the limiting ring 21 engages with the elastic member 23 and the Y-shaped limiting member 13. Then, the fixing plate 24 is installed, and the heat-conducting rod 25 on one side of the fixing plate 24 passes through the second insertion hole 17 of the graphite block 12 and the first insertion hole 16 of the annular bracket 11. When the graphite blocks 12 are affected by radial runout, they float, causing the Y-shaped limiting member 13 to deform, thus squeezing the elastic member 23. The elastic member 23 and the Y-shaped limiting member 13 fit tightly together, thereby preventing leakage at the joint between the graphite blocks 12 and the Y-shaped limiting member 13.
