Description

Technical Field

[0001] The invention belongs to the technical field of dry coke quenching, and in particular relates to a trackless coke tank transfer vehicle for dry coke quenching and a transfer method thereof. Background Art

[0002] Coke quenching is an important step in the coking process. Wet quenching or dry quenching is usually used. In the dry quenching process, circulating inert gas is used as a heat carrier. The circulating fan inputs the cold circulating gas into the red-hot coke cooling chamber to cool the high-temperature coke to below 250°C and discharge it. The circulating hot gas after absorbing the heat of the coke is introduced into the waste heat boiler to recover heat and generate steam. After cooling and dust removal, the circulating gas returns to the cooling chamber through the fan, and the cycle continues. The wet coking process is a method in which the quenching car transports the high-temperature coke to the quenching tower and directly uses water to cool the high-temperature coke. Several groups of spray heads are installed above the quenching tower to directly spray and cool down, generating a large amount of steam that emerges from the top of the quenching tower.

[0003] With the development of coking technology, environmental protection policies require the abolition of wet quenching and the gradual use of dry quenching as the main quenching method. Conventional dry quenching technology is equipped with rail-operated coke tank cars to transfer the red coke in the coke oven to the dry quenching station. In recent years, coke ovens have developed on a large scale. The dry quenching devices of newly built coke ovens in some coking plants are reasonably configured and equipped with spare stations. However, the original old coke ovens in the plant area have no spare stations for dry quenching due to plant planning restrictions, and the new and old dry quenching coke tank cars cannot communicate directly with each other, resulting in the old coke oven dry quenching device being unable to handle the red coke in an emergency when it is under maintenance or in a fault state. In order to quickly solve the emergency quenching problem of red coke in the old coke oven, the emergence of trackless transportation has become inevitable. In summary, there is an urgent need for a trackless coke tank transfer vehicle for dry quenching and a transfer method thereof. Summary of the invention

[0024] like Figure 1 As shown, the present invention provides a trackless coke tank transfer vehicle for dry coke quenching and a transfer method thereof.

[0025] On the one hand, the present invention discloses a trackless coke tank transfer vehicle for dry coke quenching. The trackless coke tank transfer vehicle is arranged between a faulty dry coke quenching station and a standby dry coke quenching station, and is used to transport a coke tank 7 at the faulty dry coke quenching station to the standby dry coke quenching station for continued quenching. The trackless coke tank transfer vehicle comprises a power locomotive 1, a carriage 2 arranged on one side of the power locomotive 1, a first frame 9 connected between the power locomotive 1 and the carriage 2, an electrical device arranged on the first frame 9 (not shown in the figure), an air circuit system arranged on the power locomotive 1 (not shown in the figure), a second frame 10 arranged at the bottom of one end of the carriage 2 away from the power locomotive 1, and a There are multiple sets of tires 4, specifically, 3 sets of tires 4 are arranged under the first frame 9, and 1 set of tires 4 and 1 set of brake wheel sets 5 are arranged under the second frame 10. Of course, in actual use, the number of brake wheel sets 5 and tires 4 needs to be set according to specific working conditions such as the overall length and load of the vehicle body. A placement platform 11 extends downward from the middle of the vehicle body 2. The placement platform 11 has a lower horizontal height than the first frame 9 and the second frame 10. Two guide frames 6 are symmetrically arranged on the placement platform 11. The overall shape of the guide frame 6 is triangular and has good stability. A coke tank 7 is arranged on the placement platform 11. The coke tank 7 is arranged between the two guide frames 6, and the coke tank 7 is an energy-saving coke tank 7.

[0026] Furthermore, in the trackless coke tank transfer vehicle for dry quenching of the present invention, the car body 2 includes platform frames arranged at both ends and a placement table 11 arranged in the middle, the platform frame and the placement table 11 are transitioned by a transition frame, and the guide frame 6 is arranged between the transition frame and the placement table 11.

[0027] Furthermore, in the trackless coke tank transfer vehicle for dry quenching of the present invention, a limit ring 12 is connected between the two guide frames 6, and the coke tank 7 is arranged in the limit ring 12. The limit ring 12 can limit the horizontal position of the coke tank 7 on the placement table 11. When the trackless coke tank transfer vehicle is traveling, the coke tank 7 is prevented from slipping, and good safety is achieved. Moreover, when the hoist lifts the coke tank 7, the limit ring 12 can also well guide the vertical movement of the coke tank 7.

[0028] As a specific embodiment, in the trackless coke tank transfer vehicle for dry quenching of the present invention, a saddle 3 is arranged between the first frame 9 and the car body 2.

[0029] As a specific embodiment, in the trackless coke tank transfer vehicle for dry quenching of the present invention, an insulating base (not shown in the figure) is arranged between the coke tank 7 and the placement platform 11. The insulating base can be directly laid on the top of the placement platform, or an insulating groove matching the insulating base can be opened on the top of the placement platform, and the insulating base is embedded in the insulating groove. Since the temperature of the red coke in the coke tank 7 is as high as 1000°C, such an arrangement can play an insulating role for the coke tank 7, greatly improve the service life of the car body 2, and avoid safety hazards.

[0030] As a specific embodiment, in the trackless coke tank transfer vehicle for dry coke quenching of the present invention, a sealing cover 8 is provided on the top of the coke tank 7. This arrangement prevents the red coke from spilling out due to road bumps during the transportation of the coke tank 7 by the trackless coke tank transfer vehicle, thereby avoiding safety hazards.

[0031] As a specific embodiment, in the trackless coke tank transfer vehicle for dry quenching of coke of the present invention, the tire 4 is a solid tire. The solid tire is used because it has a better bearing capacity and can make the trackless coke tank transfer vehicle more stable during the transportation of the coke tank 7.

[0032] On the other hand, the method for transferring coke tanks on a trackless transfer vehicle of the present invention is implemented using the above-mentioned device, and specifically comprises the following steps:

[0033] Step 1: Change the track between the faulty CDQ station and the standby CDQ station to an embedded type, so that the track height is flush with the ground, which greatly avoids the interference of the existing track with the trackless coke tank transfer vehicle;

[0034] Step 2: The elevator at the faulty dry coke quenching station lifts the redundant coke tank 7 to the designated position, and then the trackless coke tank transfer vehicle drives under the elevator at the faulty dry coke quenching station, and the coke tank 7 is lifted onto the car box 2 by the elevator, and then the sealing cover 8 is covered;

[0035] Step 3: The coke can 7 is transported to the standby dry coke quenching station by the trackless coke can transfer vehicle through the power locomotive 1, and after removing the sealing cover 8, the coke can 7 is accurately aligned, and the coke can 7 is hoisted to the standby dry coke quenching oven by the hoist at the standby dry coke quenching station for quenching;

[0036] Step 4: The trackless coke tank transfer vehicle waits at the original location. After the elevator lifts the coke tank 7 with all the red coke discharged into the car box 2, the sealing cover 8 is covered and the vehicle is driven to the elevator at the next faulty dry coke quenching station. The above steps are repeated until the transfer of all coke tanks 7 is completed.

[0037] In summary, compared with the prior art, the trackless coke tank transfer vehicle for dry coke quenching and the transfer method thereof of the present invention have the following advantages and positive effects:

[0038] When the old coke oven dry quenching device is under maintenance or in a faulty state, the present invention is used to transport the coke tank 7 at the faulty dry quenching station to the spare dry quenching station for continued quenching, so that red coke can be handled in an emergency. The solid tire 4 is adopted to make the trackless coke tank transfer vehicle more stable during the transportation of the coke tank 7. A sealing cover 8 is provided on the top of the coke tank 7 and a heat insulation seat is provided on the bottom to prevent the red coke from overflowing due to road bumps. The horizontal position of the coke tank 7 on the placement platform 11 is limited by a limiting ring 12. When the trackless coke tank transfer vehicle is traveling, the coke tank 7 is prevented from slipping. The present invention has good stability, practicality and safety.
