Description

TECHNICAL FIELD

[0001] The present application relates to coke oven dry quenching coke blocking car equipment, hoist equipment technical field, specifically a kind of vehicle-mounted coke tank whole heat preservation cover device. BACKGROUND

[0002] Rotary coke tank is used to transport red coke pushed out from carbonization chamber, and the coke tank is transported to dry quenching hoist well by motor car and coke tank trolley, and red coke is loaded into dry quenching furnace by hoist and loading device.

[0003] The continuous expansion of coke oven capacity is mainly realized by continuously increasing the height of the oven under the condition that the width of the coke oven remains unchanged. Under the condition of determined oven distance, the length of the coke tank ground trolley is also limited, and the passive increase of the carrying capacity of the coke tank can only be solved by increasing the diameter of the tank. The heat preservation cover of the coke tank also needs to be increased. The normal coke tank occupies 60% of the total length of the car. If it is a middle trolley structure, the extension length of the side wheel will occupy more than 80% of the car length. To make a whole heat preservation cover on the car, the problem of stable operation and ensuring the running distance must be solved, and the problem of not increasing or slightly increasing the process time during the process of uncovering the cover must be solved.
