Description

Technical Field

[0001] The utility model relates to the technical field of coke dry quenching in the coking industry, in particular to a coke tank cover maintenance device. Background Art

[0002] The CDQ red coke loading equipment is composed of an electric locomotive, a coke tank trolley, a rotary coke tank, an APS positioning device, an elevator, a loading device, and various limit sensors, etc. It plays the role of receiving, delivering and loading coke.

[0003] After the electric locomotive pulls the coke tank trolley and the coke intercepting car into position, the rotating coke tank starts to rotate, and after the rotation is stable, it sends a coke pushing command to the coke pushing car. After the coke is received, the rotating coke tank stops at the initial stop position after the deceleration position. After it stops completely, the electric locomotive moves to the hoist derrick, and after the empty tank is aligned, the full tank is aligned and lifted. After reaching the lifting limit, the hoist starts to move. When it reaches the top of the dry quenching furnace, the loading device is also opened in place, and the hoist starts to roll down. After the coke tank is seated, the hoist continues to roll down, and the gate at the bottom of the coke tank continues to descend with the boom under the action of gravity, automatically completing the door opening and coke release action. After the red coke falls into the hopper of the loading device, it is evenly loaded into the dry quenching furnace through the material distribution plate and the material bell.

[0004] The hoist runs on the lifting derrick and the CDQ furnace top track, lifts the coke can filled with red coke and moves it horizontally to the CDQ furnace top, and cooperates with the loading device to load the red coke into the CDQ furnace. After loading the red coke, the empty can is lifted, moved and lowered to sit on the coke can trolley. The hoist is linked with other equipment by PLC, unmanned operation, and frequency conversion speed regulation.

[0005] The elevator consists of a lifting device, a traveling device, a lubrication device, a sling, a coke tank cover, a mechanical room and various limit detection devices.

[0006] The coke tank cover is composed of a frame, refractory materials and a sealing part. It is used to isolate the heat of the coke in the coke tank and the flame from burning the surrounding equipment, and at the same time avoid the sensible heat loss of the red coke. The coke tank cover is suspended from the upper boom through a suspension rod. During operation, the coke tank cover is buckled on the coke tank. When the coke tank is seated on the coke tank trolley, the coke tank cover is supported on the bearing platform. Therefore, the suspension rod does not bear tension and only plays a guiding role.

[0007] CDQ is in long-term continuous production and operation, and the coke tank cover is in long-term continuous operation. Due to long-term direct contact with the coke in the hot coke tank full of red coke, the coke tank cover is baked by the hot coke, which leads to deformation of the coke tank cover or the falling off of fire-proof materials such as asbestos felt inside the coke tank cover. In order to ensure the normal production and operation of CDQ and the normal use of the coke tank cover, the coke tank cover is regularly inspected, handled, repaired or replaced. Due to its large size, the coke tank cover is difficult to hoist and transport. Utility Model Content
