Description

Dry quenching fixed type loading device

Technical Field

The utility model relates to a device of packing into, especially a fixed device of packing into of dry coke quenching that uses in the coal coking system.

Background

The dry quenching refers to a quenching method for cooling red coke by inert gas, compared with wet quenching. During the coke dry quenching process, red coke is loaded into a coke dry quenching furnace from the top of the coke dry quenching furnace, low-temperature inert gas is blown into a red coke layer of a cooling section of the coke dry quenching furnace by a circulating fan to absorb sensible heat of the red coke, the cooled coke is discharged from the bottom of the coke dry quenching furnace, high-temperature inert gas discharged from an annular flue of the coke dry quenching furnace flows through a coke dry quenching boiler to carry out heat exchange, the boiler generates steam, the cooled inert gas is blown into the coke dry quenching furnace again by the circulating fan, and the inert gas is recycled in a closed system. The dry quenching is superior to wet quenching in energy saving, environmental protection, coke quality improvement and the like. Dry quenching is an energy-saving and environment-friendly technology encouraged by the state, and the existing technology is a technology required by the state environmental protection agency to gradually eliminate the laggard wet quenching within 2 years, so that the coke oven is completely subjected to dry quenching within 2 years.

The dry quenching charging device is positioned at the top of the dry quenching furnace of the dry quenching device and is used for charging red coke carried by a crane into the dry quenching furnace. Its main function lies in: on one hand, opening and closing the furnace cover according to instructions and charging red coke into a dry quenching furnace through a charging hopper; on the other hand, the dust and the flue gas generated in the loading process are guided into a dry quenching dust removal system for dust removal through a dust and gas collecting pipeline. It has two functions, opening and closing the furnace cover according to instructions and charging red coke into the dry quenching furnace through a charging hopper. The prior dry quenching charging device is arranged on a platform at the top of the dry quenching furnace and mainly comprises an upper coke receiving hopper, a lower distributing hopper funnel, a hopper bracket, a movable trolley, a furnace cover, a driving device, a water sealing cover, a movable dust collecting pipeline and the like, as disclosed in patent documents with publication numbers of CN203187619U and CN 205616840U, CN 202322722U. A driving device on the driving device drives a furnace cover on the movable trolley, an upper coke receiving hopper and a lower distributing hopper to travel along the track, so that the furnace cover is opened sequentially, and the hopper is aligned to a dry quenching furnace opening; or the hopper is moved away from the dry quenching furnace mouth, and the furnace cover is closed. When in standby, the furnace cover is buckled on the dry quenching furnace mouth, and the water seal cover on the furnace cover is inserted into the water seal groove of the furnace mouth to keep the dry quenching furnace mouth sealed. When the hoister sends a red coke loading command, the driving device of the driving device starts traction action, the furnace cover is lifted at a low speed, and the whole mobile trolley starts to travel at a normal speed under the condition that the furnace cover is lifted until the discharge opening of the hopper of the loading device on the mobile trolley is aligned with the dry quenching furnace opening. And the movable trolley moves at a low speed at the final stage of the moving stroke of the movable trolley, and the water seal cover arranged at the lower hopper of the loading device falls into the water seal groove at a low speed to prevent dust at the dry quenching furnace mouth from escaping outwards during loading. When the loading device starts to act to open the furnace cover, the wear-resistant butterfly valve on the movable dust collecting pipeline is also automatically opened to start dust collection, and the raised dust produced in the current loading process is mainly in the coke loading process and the furnace cover opening process.

The existing loading device has the following problems and disadvantages: one is an integral moving type loading device, because an upper coke receiving hopper and a lower distributing hopper are arranged on a moving trolley through a bracket and move on a track along with the moving trolley, the stability of the moving part is poor due to the influence of the height and the weight of the part. When the coke drum filled with the hot coke falls on the charging device, the charging device generates a relatively large vibration because the charging device is mounted on the rail by the moving carriage. The movable dust collecting pipeline can move among different stations along with the movable trolley, and the movable dust collecting pipeline device is complex and easy to break down. The following disadvantages are reflected: 1. the stability is poor; 2. the vibration is large; 2. the output of the driving device is large; 3. the dust collecting pipeline has a complex structure; 4. the dust removal effect is poor. The other type is a split type loading device, wherein an upper coke receiving hopper is fixed on a platform through a support, a lower cloth hopper is arranged on a mobile trolley through the support, the mobile trolley still is heavy along with the movement of the mobile trolley on a track, and when the electric push rod and the mobile trolley have problems, the furnace cover cannot be quickly moved to a furnace mouth for emergency treatment. In the process of covering the furnace cover, when the furnace cover and the loading device move integrally or the lower cone bucket moves, the dust suction opening is partially opened to the whole process, so that the suction force required by dust suction cannot be met even if the dust suction air quantity is large.
