Description

Technical Field

[0001] This utility model relates to the technical field of coke pot liners, specifically a dry quenching coke pot liner that is easy to replace. Background Technology

[0002] Coke can liners are key components in dry quenching systems used to support and protect coke cans. They come into direct contact with hot coke at approximately 1100°C and must possess properties such as wear resistance, high temperature resistance, and impact resistance. Traditional liners are mostly made of heat-resistant cast steel or alloy materials, but they suffer from problems such as high thermal conductivity leading to large heat loss, easy deformation and cracking, and short service life (only 0.5-1 year). They may even cause equipment failure due to detachment. Therefore, coke can liners need to be replaced every once in a while. The conventional method of installing coke can liners is to install them on the bracket inside the coke can using bolts or limiting components. The installation bolts and limiting components are exposed on the outside of the coke can liner. These components are not as heat-resistant as the coke can liner and have a higher probability of damage, which affects the replacement of the coke can liner. Utility Model Content

[0003] The purpose of this invention is to provide a dry quenching coke pot liner that is easy to replace, in order to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dry quenching coke pot liner that is easy to replace, comprising; The coke oven outer liner and the coke oven inner liner are provided, with the coke oven inner liner embedded in the coke oven outer liner. The coke oven outer liner is provided with a snap-fit ​​assembly, which includes connector A, a snap plate, connector B, and a snap piece. One end of connector A is hinged to connector B. A limiting groove is provided on the outer liner of the coke tank. Connector B passes through the limiting groove and is embedded inside the outer liner of the coke tank. Connector B is perpendicular to connector A, and the inner liner of the coke tank is fastened to the outside of connector B and fits against it. The top of connector A has two symmetrical retaining plates. The top of connector A has a through groove on the side of the retaining plate, and the top of the retaining plate passes through the through groove and fits against the retaining plate.

[0005] Preferably, the outer side of the coke oven inner liner is provided with a handle groove, the bottom of the coke oven inner liner has an integrally fixed protrusion, and the outer liner of the coke oven is provided with a slot. The protrusion is embedded in the slot and engages with the outer liner of the coke oven for positioning. The coke oven inner liner can be pulled out and separated from the outer liner by inserting a hook into the handle groove. When the coke oven inner liner is embedded in the outer liner of the coke oven, it presses against the limiting groove and engages with the slot, thereby limiting the connection piece B and fixing the coke oven outer liner to the connection piece B, preventing the coke oven outer liner from falling off.

[0006] Preferably, the top of the clamp is provided with a symmetrical U-shaped groove, and the clamp plate has an integrally fixed threaded rod. A nut is fitted on the outside of the threaded rod for limiting and fixing.

[0007] Preferably, the inner side of the coke oven outer liner is provided with a maintenance groove, through which nuts can be removed and installed. The internal installation structure makes the combined surface of the coke oven outer liner and the coke oven inner liner smoother, preventing nuts from being on the outside of the coke oven outer liner, thus preventing nuts from being exposed to high temperatures and increasing their service life.

[0008] Preferably, the outer side of the clamp has multiple integrally fixed clamping blocks with a triangular structure. The inner side of the coke tank liner is provided with a triangular groove. When the coke tank liner is attached to the clamp, the clamping blocks are embedded in the corresponding triangular grooves to limit the structure and prevent the equipment from shaking during use.

[0009] Preferably, one end of the clip is fixedly connected to a mounting bracket, which is fixed inside the coke tank by welding.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model allows for the removal and installation of nuts via an inspection slot. The internal installation structure makes the combined surface of the coke oven outer liner and the coke oven inner liner smoother, preventing the nuts from being exposed to the outside of the coke oven outer liner, thus avoiding the nuts being exposed to high temperatures and increasing their service life.

[0016] Please see Figure 1-2 This utility model provides a technical solution: a dry quenching coke pot liner that is easy to replace, comprising; The coke tank outer liner 100 and the coke tank inner liner 200 are embedded in the coke tank outer liner 100. The coke tank outer liner 100 is provided with a snap-fit ​​assembly, which includes a connector A300, a snap plate 302, a connector B304, and a snap piece 401. One end of connector A300 is hinged to connector B304. A limiting groove 102 is provided on the coke tank outer liner 100. Connector B304 passes through the limiting groove 102 and is embedded inside the coke tank outer liner 100. Connector B304 is perpendicular to connector A300, and the coke tank inner liner 200 is fastened to the outside of connector B304 and fits against it. The top of the connector A300 has two symmetrical retaining plates 302. The top of the connector A300 is provided with a through groove 301 on the side of the retaining plate 302. The top of the retaining piece 401 passes through the through groove 301 and fits against the retaining plate 302.

[0017] Furthermore, a handle groove 201 is provided on the outer side of the coke oven inner liner 200, and an integrally fixed protrusion 202 is provided on the bottom of the coke oven inner liner 200. A slot 103 is provided on the coke oven outer liner 100. The protrusion 202 is embedded in the slot 103 and engages with the coke oven outer liner 100 for positioning. The coke oven inner liner 200 can be pulled out and separated from the coke oven outer liner 100 by inserting a hook into the handle groove 201. When the coke oven inner liner 200 is embedded in the coke oven outer liner 100, it presses against the limiting groove 102 and engages with the slot 103, thereby limiting the connection piece B304, so that the coke oven outer liner 100 and the connection piece B304 are installed and fixed, preventing the coke oven outer liner 100 from falling off.

[0018] Furthermore, the top of the clamp 401 is provided with symmetrical U-shaped grooves, and the clamp plate 302 has an integrally fixed threaded rod 303. The outer side of the threaded rod 303 is fitted with a nut for limiting and fixing.

[0022] Working principle: In use, connector B304 is passed through the inspection slot 101 and rotated. Connector B304 is perpendicular to connector A300, so that connector B304 fits against the inner wall of the coke tank outer liner 100. Then, the protrusion 202 at the bottom of the coke tank inner liner 200 is inserted into the slot 103, pressing the coke tank inner liner 200 so that it fits against connector B304, thereby fixing connector B304 and making the coke tank... The outer liner 100 is installed and fixed to the connector A300. Then, the top of the clamp 401 is aligned with the through groove 301 and inserted, so that the threaded rod 303 passes through the clamp 401. The threaded rod 303 is installed and fixed by the nut, so that the clamp 401 and the connector A300 are installed and fixed. When the clamp 401 is inserted into the through groove 301, the clamp block 402 is embedded in the triangular groove on the inner side of the coke tank outer liner 100 to perform structural limiting and prevent the equipment from shaking during use.
