Description

Technical Field

[0001] The utility model relates to the technical field of dry coke quenching, and more specifically to a coke tank cover for a dry coke quenching coke tank. Background Art

[0002] During the dry coke quenching production process, the coke can needs to be frequently covered at the bottom of the hoisting derrick and lifted to the top of the hoist. During the covering operation, the hoist lifts the coke can so that the coke can cover and the coke can are sealed and docked. The entire operation process requires the operator to stand on the platform to operate.

[0003] However, in actual operation, the platform is higher than the ground and there are no protective measures on the platform. When the operator stands on the platform to operate, when the coke drum cover is lifted, the mouth of the coke drum is open to the outside, and there are no protective measures around the coke drum, which makes it easy for the operator to fall into the coke drum, posing a huge safety hazard. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a coke tank cover for a dry coke quenching coke tank, which protects a platform and the surrounding side of the coke tank and reduces safety hazards.

[0005] In order to solve the above technical problems, the technical solutions adopted by the present utility model are as follows.

[0006] A coke tank cover for a dry coke quenching coke tank comprises a coke tank cover body, four lifting frames are arranged on the coke tank cover body, and platforms for operators to stand are arranged on the sides of the lifting frames; the platform is arranged on the ground through stairs, and railings for protecting the stairs and the platform are arranged on both sides of the platform and the stairs as well as at the rear end of the platform; arc-shaped railings for protecting the mouth of the coke tank are arranged at the coke tanks on the front and rear sides of the coke tank cover body, and the curvature of the railings is consistent with the curvature of the outer edge of the coke tank cover body.

[0007] To further optimize the technical solution, four vents for ventilating the coke tank are arranged on the coke tank cover body.

[0008] To further optimize the technical solution, the lifting frame is provided with an inclined support for enhancing the stability of the lifting frame.

[0009] To further optimize the technical solution, an annular sealing plate is provided on the bottom peripheral side of the coke can cover body to improve the sealing performance between the coke can cover body and the coke can.

[0010] To further optimize the technical solution, a heat insulation plate for heat insulation is provided at the bottom of the sealing plate.

[0011] Due to the adoption of the above technical scheme, the technical progress achieved by the present invention is as follows.

[0012] The utility model provides a coke tank cover for a coke dry quenching coke tank, which protects operators on the platform by arranging railings around a platform and stairs. The railings at the mouth of the coke tank can protect the open mouth of the coke tank, reduce safety hazards, and prevent operators and outsiders from falling into the coke tank.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] A coke tank cover for dry quenching coke tank, combined with Figures 1 to 3 As shown, the coke tank cover body 1 includes four lifting frames 3, and the lifting frames 3 are provided with inclined supports 4 to enhance the stability of the lifting frames. A platform 5 is provided on the side of the lifting frames 3, and the platform 5 is provided on the ground beside the coke tank through a staircase 6.

[0019] The left and right sides of the platform 5 and the stairs 6 and the rear end of the platform 5 are provided with railings 7 to protect the stairs and the platform to prevent operators from falling on the platform and in the process of going up the platform, reduce safety hazards, and ensure the safety of the operators.

[0020] Arc-shaped railings 7 are arranged at the coke tank on the front and rear sides of the coke tank cover body 1 to protect the mouth of the coke tank and prevent people from falling into the coke tank. The curvature of the railings is consistent with the curvature of the outer edge of the coke tank cover body 1.

[0021] Four vents 8 are provided on the coke tank cover body 1 for ventilating the coke tank.

[0022] An annular sealing plate 2 is arranged on the bottom peripheral side of the coke tank cover body 1, and the sealing plate is matched with the mouth of the coke tank to improve the sealing performance between the coke tank cover body and the mouth of the coke tank.

[0023] A heat insulation plate 9 is arranged inside the sealing plate 2 to insulate the coke tank and prevent the heat of the coke tank from being dissipated. At the same time, it can also prevent operators from touching the coke tank cover and getting burned, thereby reducing safety hazards.

[0024] When the utility model is working, a hoist is used to move the coke tank cover body to the top of the coke tank, and then the coke tank cover body is slowly lowered to the mouth of the coke tank. During the operation, the railings protect the operators on the platform, and the railings at the mouth of the coke tank can protect the open mouth of the coke tank, thereby reducing safety hazards and preventing operators and outsiders from falling into the coke tank.
