Description

Coke jar cover with guide piece and rolling hanger

Technical Field

The invention relates to a coke can cover, in particular to a coke can cover with a guide part and a rolling hanging bracket.

Background

The coke dry quenching is an important technology and process for saving energy and reducing emission in the steel industry, and is a method for quenching coke by gas-solid phase heat exchange between inert gas and red coke in a coke dry quenching furnace. The coke drum is a dry-quenched red coke loading device used to ship red coke pushed out of the coke oven coking chamber. After the coke tank is filled with red coke, the red coke is conveyed to the position below a dry quenching lifting derrick by a coke tank carrying vehicle and then lifted to a dry quenching loading device by a lifter to finish coke loading.

At present, the coke dry quenching coke tank is not covered in the transportation process of a coke tank carrying vehicle, and the coke tank is covered by a coke tank when a lifter lifts the coke tank. In the transportation process of the coke tank, because the red coke is directly combusted with oxygen in the air, a large amount of carbon dioxide is generated and discharged into the air, the energy consumption for coking is increased, and the atmosphere is polluted; in addition, the burning of coke in the coke drum may burn off the lining plate at the mouth of the coke drum, resulting in an increase in the maintenance cost of dry quenching.

Therefore, a coke pot covering and uncovering device I (shown in figure 1) is designed, a front tongue plate 3 and a rear tongue plate 4 of the coke pot covering and uncovering device I are used for hanging a coke pot cover II, a driving device 1 and a link mechanism 2 are used for adjusting the inclination angles of the front tongue plate 3 and the rear tongue plate 4, so that the coke pot cover II automatically moves along the upper edges of the front tongue plate 3 and the rear tongue plate 4 through a top rolling hanger, thereby completing the automatic covering and uncovering action on the coke pot III in the process of transporting the coke pot III by a coke pot carrier IV, and avoiding the adverse effect caused by the direct exposure of red coke in the coke pot III in the atmosphere.

Disclosure of Invention

The invention provides a coke pot cover with a guide part and a rolling hanger, wherein the guide part is used for being matched with a guide wheel arranged at the top of a coke pot carrier loader and used as a moving alignment and cover adding/uncovering triggering mechanism; the rolling hanger is provided with a front rolling shaft and a rear rolling shaft which can respectively move along the front tongue plate and the rear tongue plate of the coke tank covering and uncovering device, so that the coke tank can be automatically covered/uncovered during the process of transporting the coke tank by the coke tank carrier loader; the coke tank cover is also provided with a fire guiding device, and the opening pressure value can be set by adjusting the balance weight.

Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings:

as shown in figures 2-5, the coke jar cover with the guide member and the rolling hanger comprises a coke jar cover II, wherein a heat insulation layer 9 and a sealing ring 10 are arranged at the bottom of the coke jar cover II; the top of the coke tank cover II is provided with a front hanger, a rear hanger and a fire guiding device, and the outer side of the coke tank cover II close to the front hanger is provided with a U-shaped guide part 14 which extends to the lower part of the coke tank cover II and is provided with a downward opening; the front hanger is composed of a front hanger seat 5 and a front roller 6, the rear hanger is composed of a rear hanger seat 7 and a rear roller 8, and the front roller 6 and the rear roller 8 are horizontally erected above the coke tank cover II through the

corresponding hanger seats

5 and 7 respectively; the U-shaped guide 14 is transversely provided with a U-shaped guide groove, and the front roller 6, the rear roller 8 and the U-shaped guide groove are arranged in parallel; the length of the inner side of the U-shaped guide 14 is shorter than the length of the outer side, and the bottom of the inner side has a circular arc transition structure.
