Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protective device equipment, in particular to a novel blast protective device for dry quenching tanks containing cold coke. Background Art
[0002] Coke Cooling The coke after wet quenching is unloaded onto the inclined coke cooling table for cooling. The coke usually stays on the coke cooling table for about 30 minutes to evaporate the water and quench the remaining red coke. There are two ways of quenching coke: wet quenching and dry quenching. The former is to use a quenching car to carry the red coke out of the furnace to the quenching tower and spray it with water. The latter is to use an inert gas of about 180℃ to countercurrently pass through the red coke layer for heat exchange. The coke is cooled to about 200℃, and the inert gas is heated to about 800℃.
[0003] The new type of air blast protection device for cold coke in the dry quenching tank only relies on the upper blast hood protective cover, the lower blast hood protective tape, the cross air duct and the cast stone slab protective umbrella frame to protect the air blast. The new type of air blast protection device for cold coke in the dry quenching tank is not equipped with a smoke exhaust device, which causes the smoke generated during the cold coke in the dry quenching tank to easily enter the interior of the blower, and then easily damage the blower, resulting in poor use effect of this equipment, and therefore needs to be improved.

[0006] By adopting the above technical scheme, the staff inputs the inert gas into the interior of the dry quenching tank containing hot coke through the channel port, and then turns on the blower. The blower blows the inert gas to move, so that the inert gas is in contact with the surface of the hot coke faster. After the inert gas contacts the hot coke, heat exchange is achieved, so that the coke is cooled, and a large amount of smoke is generated during the heat exchange. At this moment, the motor is started and the motor starts to work.

[0007] The utility model is further configured as follows: a hollow filter box is fixedly connected to the outside of the through pipe, and a filter layer is fixedly connected to the inside of the hollow filter box.
[0008] By adopting the above technical solution, the hollow filter box and the filter layer filter out impurities in the smoke, preventing the impurities in the smoke from entering the interior of the motor box and damaging the high-speed rotating centrifugal fan blades.
[0009] The utility model is further configured as follows: an inverted triangular pleated plate is fixedly connected to the inside of the air outlet duct, and the distances between any two of the inverted triangular pleated plates are equal.
[0010] By adopting the above technical solution, the inverted triangular pleated plate intercepts large particles in the smoke, so that the large dust particles in the smoke are adsorbed around the inverted triangular pleated plate, and the pollution of the gas discharged from the air outlet pipe to the atmosphere is reduced.
[0011] The utility model is further configured as follows: baffles are fixedly connected inside the dry quenching tank, and the intervals between any two of the baffles are equal.
[0012] By adopting the above technical solution, the baffle changes the movement trajectory of the rising smoke inside the dry quenching tank, blocks the rising of a part of the smoke, and prevents the generated smoke from rising directly.
[0013] The utility model is further configured as follows: an equipment platform is fixedly connected to the outside of the passage opening, and a hydraulic press is fixedly connected to the upper surface of the equipment platform.
[0014] By adopting the above technical solution, the hydraulic press provides power for the movement of the rain shield.
[0015] The utility model is further configured as follows: a rain shield is provided on the outside of the equipment platform, a pulley is provided at the bottom of the rain shield, the pulley is slidably connected to the upper surface of the passage opening, and the output end of the hydraulic press is fixedly connected to the rain shield.
[0016] By adopting the above technical solution, when it rains, the hydraulic press is started, and the output end of the hydraulic press drives the rain shield to move, thereby covering the channel opening and preventing rain from pouring on the blower.
[0017] The beneficial effects of the utility model are:
