Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of coke guide car coke receiving equipment technology, specifically related to a coke guide car coke receiving hopper damping device. BACKGROUND

[0002] The coke oven is an indispensable equipment in the steel smelting process, and its production process involves multiple complex and delicate operation steps, among which coke pushing and coke receiving are two particularly key links. During the coke receiving process of the coke guide car, a large amount of scattered coke powder is often produced due to the fragmentation of the coke and the opening of the oven door. If these coke powders are not collected in time and effectively, not only will they fall on the oven front operating table, polluting the working environment, but also may pose a potential threat to the normal operation of the coke oven. In order to solve this problem, a coke receiving hopper device is specially introduced in the design of the coke oven. The main function of this device is to collect scattered coke powder. The coke receiving hopper device is ingeniously arranged in front of the coke guide groove, and its unique design includes a head-tail coke receiving hopper that can be tilted and moved. In the initial stage of the out-of-furnace operation, the coke receiving hopper will be driven by the hydraulic cylinder to rotate downward by about 90 degrees, accurately falling below the carbonization chamber between the oven columns. The purpose of this action is to recover the tail coke produced during the coke-out process, ensuring that these scattered cokes do not scatter everywhere.

[0003] After the coke side oven door is closed, the coke receiving hopper will again be driven by the hydraulic cylinder to rotate upward by 90 degrees, pouring the previously recovered tail coke into the coke guide groove. With the next coke pushing operation, these collected scattered cokes will be sent into the coke tank, thereby achieving effective collection and utilization of the tail coke. This design not only greatly reduces the scattering of coke powder, but also effectively improves the production efficiency and environmental performance of the coke oven. It is worth noting that the coke receiving hopper device adopts a double-oil-cylinder synchronous driving design to ensure its stability and accuracy. However, due to the large weight of the coke receiving hopper itself, a large inertia will be generated during the 90-degree rotational motion, especially during the process of turning over from top to bottom. The impact on the bearing seat and coke hopper trolley track is particularly significant. This impact not only may cause damage to the bearing seat and coke hopper trolley track, but also may affect the service life and stability of the entire coke receiving hopper device. In summary, there is an urgent need for a coke receiving hopper damping device for a coke guide car. UTILITY MODEL CONTENTS
