TECHNICAL FIELD

[0001] The utility model belongs to the dry quenching furnace equipment technical field relates to a dry quenching furnace central wind cap protection device. BACKGROUND

[0002] Coking dry quenching process refers to a kind of quenching method for cooling red coke pushed out from coke oven by inert gas.As the core equipment of dry quenching system, dry quenching hoist is special equipment, and it runs on lifting tower and dry quenching furnace top track, cooperates with loading device, and loads red coke into dry quenching furnace.The bottom of dry quenching furnace cooling section is provided with gas supply device, which uniformly supplies gas to the entire dry quenching furnace cross section.

[0003] The bottom of the cooling section of the dry quenching furnace is provided with a gas supply device, which is composed of a wind cap, a cross air duct, an upper cone hopper and a lower cone hopper.When loading coke into the cooling section of the dry quenching furnace, the central wind cap in the gas supply device will be worn out, so it is necessary to check the wear condition of the central wind cap and the cross air duct after the coke in the dry quenching furnace is completely emptied in order to load coke subsequently, which will affect the use efficiency of the dry quenching furnace, and in addition, the central wind cap needs to be repaired or replaced when it is worn to a certain extent, which increases the corresponding cost. UTILITY MODEL CONTENT

[0004] The utility model aims at the problem of wearing central wind cap during loading coke into dry quenching furnace in the background art, and provides a dry quenching furnace central wind cap protection device.

[0005] Therefore, the utility model takes the following technical scheme:

[0006] A dry quenching furnace central wind cap protection device, comprising a central wind cap in conical structure, a protective cover in upper-small-lower-large conical structure is covered on the central wind cap, a base in cylindrical structure is fixed to the bottom end of the protective cover, the bottom of the base forms a bevel, the bevel is in close contact with the central wind cap, and a lifting hook is arranged at the top end of the protective cover.

[0007] Further, the taper of the protective cover is smaller than that of the central wind cap.

[0008] Further, a reinforcing rib plate is arranged in the protective cover, and the reinforcing rib plate is located at the top of the protective cover.

[0009] Further, a plurality of lifting rings are arranged on the protective cover.

[0010] The dry quenching furnace central air cap protection device has the advantages that the central air cap is covered by the protective cover, the central air cap is effectively protected, the maintenance and replacement frequency of the central air cap are reduced, the service life of the central air cap is prolonged, the cost is effectively saved, and the use efficiency of the dry quenching furnace is improved; the rib plate is arranged in the protective cover, the strength of the protective cover is increased, and the use effect is improved; the structure is simple, and the use mode is convenient. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 It is a structural schematic view of the utility model;

[0012] In the figure, 1 is a central air cap, 2 is a protective cover, 3 is a base, 4 is a reinforcing rib plate, 5 is a lifting hook, and 6 is a lifting ring. DETAILED DESCRIPTION

[0013] The utility model will be described in detail in combination with the drawings:

[0014] As Figure 1 shown, a dry quenching furnace central air cap protection device, including the central air cap 1 of the taper structure, the central air cap 1 is covered with the protective cover 2 of the taper structure of small on big down, specifically, the protective cover can adopt stainless steel structure, the taper of protective cover 2 is less than the taper of central air cap 1, so that protective cover 2 and central air cap 1 have enough gap, the diameter of the bottom end of protective cover 2 is greater than the diameter of the bottom end of central air cap 1, when the coke falls down in the top end of dry quenching furnace, due to the block of protective cover 2 can effectively avoid directly hitting central air cap 1, cause central air cap 1 damage, the bottom end of protective cover 2 is fixed with the base 3 of the cylinder type structure, the diameter of base 3 is consistent with the diameter of the bottom end of protective cover 2, base 3 is used to prop up central air cap 1, to ensure the strength of protective cover 2, the reinforcing rib plate 4 is arranged in protective cover 2, the reinforcing rib plate 4 can be installed in protective cover 2 by welding, the reinforcing rib plate 4 is located at the top of protective cover 2, by the reinforcing rib plate 4 can effectively prevent the deformation of protective cover 2 under the impact of coke, improve the use effect, the top of protective cover 2 is provided with the lifting hook 5, when needing to place protective cover in dry quenching furnace and cover central air cap 1, only need to use electric hoist or other existing conventional equipment is connected with electric hoist through lifting hook 5, then protective cover 2 can be placed in dry quenching furnace and cover central air cap 1, when use is finished, lifting hook 2 is lifted out.

[0015] The protective cover 2 is also provided with a plurality of lifting rings 6, and two lifting rings 6 are provided in the embodiment. When it is necessary to transport and move the protective cover 2, the two lifting rings 6 can be used to ensure the stability during transportation.

[0016] The use mode of the utility model is as follows:

[0017] When the coke is loaded into the cooling section of the dry quenching furnace, the protective cover 2 is moved into the dry quenching furnace from top to bottom by the electric hoist, then covers the central air cap 1, and then the coke can be loaded into the cooling section of the dry quenching furnace. The coke directly falls on the protective cover 2 and does not contact the central air cap 1, which can effectively prevent the central air cap 1 from being damaged by impact. After the coke is added, the protective cover 2 is removed. Since the rib plate 4 is arranged in the protective cover 2, the deformation or breakage of the protective cover 2 under external force can be effectively prevented, and the protection effect is further improved.

[0018] Using the device can effectively protect the central air cap 1, reduce the maintenance and replacement frequency of the central air cap 1, effectively save costs, and improve the use efficiency of the dry quenching furnace.
