Description
Technical Field
[0001] This utility model belongs to the field of kiln mouth castable anti-detachment technology, specifically relating to a kiln mouth castable anti-detachment nail structure. Background Technology
[0002] The anti-detachment nail structure for kiln inlet castable is an important design feature of key parts of industrial kilns (such as cement kilns and metallurgical kilns). It is used to enhance the anchoring ability of the castable to the steel shell of the kiln body and prevent the castable from falling off under high temperature, thermal shock or mechanical stress.
[0003] A utility model patent with patent authorization announcement number CN201954940U discloses a cement rotary kiln inlet structure, which includes a kiln inlet body, a kiln inlet iron at the kiln inlet body opening, and a casting layer for the kiln inlet. The axial length of the kiln inlet body is designed to be 1.0m, and the thickness of the casting layer for the kiln inlet is 250mm. The rakes in the casting layer are L-shaped rakes and are arranged in a cross pattern.
[0004] However, the existing anti-detachment nails for kiln inlet castables mainly use Y-type nails. The front and side of the Y-type nail are not a whole, making it difficult to connect the front and side. This results in weak connection stability and support of the kiln inlet castable, which easily leads to subsequent detachment problems. Summary of the Invention
[0005] The purpose of this utility model is to provide a structure for preventing detachment of kiln inlet castable, which solves the problem that the existing kiln inlet castable anti-detachment nails mainly use Y-shaped nails. However, the front and side of the Y-shaped nail are not a whole, making it difficult to connect the front and side, resulting in weak connection stability and support of the kiln inlet castable, which easily leads to subsequent detachment problems.
[0006] To achieve the above objectives, this utility model provides a kiln inlet castable anti-detachment nail structure, including a kiln inlet body. A fixing block is fixedly connected to the inner wall of the kiln inlet body. An installation block is contacted on the end face of the fixing block. A G-shaped nail is fixedly connected to the end face of the installation block. A locking mechanism is provided on both the installation block and the fixing block. A slot is formed on the surface of the G-shaped nail. A support ring is slidably connected to the inner wall of the slot. A locking hole is formed on the end face of the G-shaped nail. A limiting piece is contacted on the end face of the G-shaped nail. The limiting piece is in contact with the support ring. An elastic ball is fixedly connected to the end face of the limiting piece. The elastic ball is slidably connected to the locking hole.
[0007] The principle of this utility model is as follows: by pushing the mounting block to contact the fixing block, the positioning block is inserted into the fixing block, and the mounting block is quickly positioned. Then, the non-standard bolt is pushed through the mounting block, so that the non-standard bolt contacts the fixing block. The non-standard bolt is rotated and fixed under the threaded connection, so that the round end contacts the kiln body. During this process, the round end rotates forward under force. When the round end contacts the limiting rod, it can push the limiting rod to move, causing the spring to deform. Finally, the limiting rod contacts the surface of the non-standard bolt. Under the action of force, the limiting rod slides along the surface of the non-standard bolt. When the limiting rod slides into the limiting groove, the spring returns to its original deformation to pull the limiting rod into the limiting groove, thus limiting the non-standard bolt and avoiding the problem of vibration and loosening of the non-standard bolt, so as to ensure the stable placement of the G-shaped pin. By setting the slot, the support ring can be pushed into the G-shaped pin, and the limiting plate can be pushed to contact the end face of the G-shaped pin, so that the limiting plate and the support ring are in contact. Under the pressure of the force, the elastic ball can be squeezed into the hole, so that the limiting plate is stable and effectively limits the support ring. In conjunction with the action of the G-shaped pin, it can provide stable support for the kiln inlet castable and improve the anti-detachment effect of the kiln inlet castable.
[0008] The beneficial effects of this utility model are as follows: This solution, through the action of positioning blocks, non-standard bolts, and other structures, can install the mounting block, thereby fixing the G-shaped pins. Furthermore, through the action of limiting grooves, limiting rods, and other structures, the non-standard bolts can be limited, preventing vibration and loosening. The G-shaped pins can connect the side and front of the kiln inlet castable to ensure good stability and improve the anti-detachment effect of the kiln inlet castable. The slot design allows for quick placement and use of the support ring, and the locking holes and elastic balls allow the limiting plates to limit the support ring, preventing it from detaching. Combined with the action of the G-shaped pins, this improves the support for preventing the kiln inlet castable from detaching.
[0009] Furthermore, multiple fixing blocks are provided, and the multiple fixing blocks are arranged in a circular array on the kiln body. The setting of fixing blocks facilitates the installation and use of subsequent mounting blocks.
[0010] Furthermore, multiple locking holes are provided, and these holes are evenly arranged on the G-shaped pin. The locking holes facilitate the use of elastic locking balls for engagement.
[0011] Furthermore, the locking mechanism includes a positioning block, with the positioning block fixedly connected to the end face of the mounting block. The positioning block is slidably connected to the fixing block. A non-standard bolt is movably connected to the inner wall of the mounting block. The non-standard bolt is threaded to the fixing block. A limit groove is formed on the surface of the non-standard bolt. A limit rod is slidably connected to the inner wall of the fixing block. The limit rod is slidably connected to the limit groove. An end piece is fixedly connected to the lower end of the limit rod. The end piece contacts the fixing block and the kiln mouth body. A spring is provided on the outer side of the limit rod. Through the setting of the non-standard bolt and the positioning block, the mounting block can be locked, and under the action of the limit groove, the limit rod and other structures, the non-standard bolt can be limited, avoiding the problem of vibration and loosening of the non-standard bolt.
[0012] Furthermore, multiple limiting grooves are provided, and these multiple limiting grooves are arranged in a circular array on the non-standard bolt. The setting of the limiting grooves facilitates the insertion and use with the limiting rod.
[0013] Furthermore, the non-standard bolt has a round end fixedly connected to its end face. The round end contacts the kiln mouth body, and the round end allows the limiting rod to be pressed.
[0014] Furthermore, one end of the spring is fixedly connected to the end piece, and the other end of the spring is fixedly connected to the fixing block. The end piece can be connected and used by means of the spring. Attached Figure Description

Detailed Implementation
[0017] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment provides a kiln mouth castable anti-detachment nail structure, including a kiln mouth body 1, a fixing block 2 fixedly connected to the inner side wall of the kiln mouth body 1, an installation block 3 contacting the end face of the fixing block 2, a G-shaped nail 4 fixedly connected to the end face of the installation block 3, a slot 6 formed on the surface of the G-shaped nail 4, a support ring 7 slidably connected to the inner wall of the slot 6, a locking hole 8 formed on the end face of the G-shaped nail 4, a limiting piece 9 contacting the limiting piece 9 and the support ring 7, and an elastic ball 10 fixedly connected to the end face of the limiting piece 9, the elastic ball 10 slidably connected to the locking hole 8.
[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, multiple fixing blocks 2 are provided, and the multiple fixing blocks 2 are arranged in a ring array on the kiln body 1. The setting of fixing blocks 2 facilitates the subsequent installation of mounting blocks 3. Multiple locking holes 8 are provided, and the multiple locking holes 8 are evenly arranged on the G-shaped pins 4. The setting of locking holes 8 facilitates the use of elastic locking balls 10 for locking.
[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a locking mechanism 5 is provided on both the mounting block 3 and the fixing block 2. The locking mechanism 5 includes a positioning block 50. The positioning block 50 is fixedly connected to the end face of the mounting block 3 and is slidably connected to the fixing block 2. A non-standard bolt 51 is movably connected to the inner wall of the mounting block 3 and is threadedly connected to the fixing block 2. A limit groove 52 is provided on the surface of the non-standard bolt 51. A limit rod 54 is slidably connected to the inner wall of the fixing block 2 and is slidably connected to the limit groove 52. An end piece 55 is fixedly connected to the lower end of the limit rod 54 and is in contact with the fixing block 2 and the kiln body 1. A spring 56 is provided on the outer side of the limit rod 54. The mounting block 3 can be locked by the non-standard bolt 51 and the positioning block 50. Under the action of the limit groove 52, the limit rod 54 and other structures, the non-standard bolt 51 can be limited to avoid the problem of the non-standard bolt 51 oscillating and loosening.
[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, multiple limiting grooves 52 are provided, and the multiple limiting grooves 52 are arranged in a ring array on the non-standard bolt 51. The setting of the limiting grooves 52 facilitates the insertion and use of the limiting rod 54. The end face of the non-standard bolt 51 is fixedly connected to a round end 53, which contacts the kiln body 1. The setting of the round end 53 allows the limiting rod 54 to be pressed. One end of the spring 56 is fixedly connected to the end piece 55, and the other end of the spring 56 is fixedly connected to the fixing block 2. The setting of the spring 56 allows the end piece 55 to be connected.
[0021] The specific implementation process of this utility model is as follows: By pushing the mounting block 3 to contact the fixing block 2, the positioning block 50 is inserted into the fixing block 2, and the mounting block 3 is quickly positioned. Then, the non-standard bolt 51 is pushed through the mounting block 3, so that the non-standard bolt 51 contacts the fixing block 2. The non-standard bolt 51 is rotated and fixed under the threaded connection, so that the round end 53 contacts the kiln mouth body 1. During this process, the round end 53 rotates forward under force. When the round end 53 contacts the limiting rod 54, it can push the limiting rod 54 to move, causing the spring 56 to deform. Finally, the limiting rod 54 contacts the surface of the non-standard bolt 51. Under the action of force, the limiting rod 54 slides along the surface of the non-standard bolt 51. When the limiting rod 54 slides into the limiting groove 52, the spring 56 restores its deformation to pull the limiting rod 54 into the limiting groove 52, thereby limiting the non-standard bolt 51 and avoiding the problem of oscillation and loosening of the non-standard bolt 51, so as to ensure the stable placement of the G-shaped pin 4. By setting the slot 6, the support ring 7 can be pushed into the G-shaped nail 4, and the limiting piece 9 can be pushed to contact the end face of the G-shaped nail 4, so that the limiting piece 9 and the support ring 7 are in contact. Under the pressure of the force, the elastic ball 10 can be squeezed into the hole 8, so that the limiting piece 9 is stable and effectively limits the support ring 7. Together with the action of the G-shaped nail 4, it can provide stable support for the kiln inlet castable and improve the anti-detachment effect of the kiln inlet castable.
[0022] This solution utilizes structures such as positioning block 50 and non-standard bolt 51 to install mounting block 3, thereby fixing G-shaped pin 4. The limiting groove 52 and limiting rod 54 limit the non-standard bolt 51, preventing it from vibrating and loosening. The G-shaped pin 4 connects the side and front of the kiln inlet castable to ensure good stability and improve its anti-detachment effect. The slot 6 allows for quick placement of support ring 7, and the locking hole 8 and elastic ball 10 limit the support ring 7 with the limiting piece 9, preventing it from detaching. Combined with the G-shaped pin 4, this enhances the support for the kiln inlet castable.
