Description

Technical Field

[0001] The utility model belongs to the technical field of dry quenching furnaces, and in particular relates to an automatic feeding mechanism for dry quenching furnaces. Background Art

[0002] The traditional CDQ coke oven feeding process generally includes the following steps: the coke pushing mechanism pushes the coke out of the coke oven carbonization chamber, and then the coke is loaded into the coke can. The coke can is transported to the designated location by a transport vehicle, and then the coke can is lifted by the coke can elevator and sent to the top of the CDQ furnace, and then the coke is loaded into the CDQ furnace. The steps are relatively complicated.

[0003] CDQF usually uses an automated production line to simplify the workflow and is used to send raw materials to the CDQF through coke drums for processing. This mechanism usually includes a conveyor belt. The function of the automatic feeding mechanism is to achieve an efficient and automated production process, thereby improving production efficiency and controlling production costs. At the same time, they can also reduce human contact and improve work safety.

[0004] However, the conveyor belt needs to rotate forward to transport the transport vehicle detachably connected to the coke tank to a specified position, and then reverse to transport the transport vehicle detachably connected to the coke tank from the specified position to the initial position. The drive motor corresponding to the conveyor belt needs to run for a long time, consumes a lot of power, and requires frequent forward and reverse rotation, which reduces the actual service life of the drive motor.

[0024] (6) The two ends of the vibration-absorbing spring are detachably connected to the absorber connecting plate and the upper end of the side of the traction rope respectively. The vibration-absorbing spring plays a role in absorbing vibration, ensuring that the traction rope does not shake violently, thereby improving the stability of the coke tank operation.

The end of the limiting protrusion 23 away from the sliding vehicle body 21 is slidably connected to the first limiting groove 74, and the end of the limiting protrusion 24 away from the sliding vehicle body 21 is slidably connected to the second limiting groove 75.

[0050] like Figure 1 and Figure 3As shown, the guardrail protection mechanism 7 also includes a buffer fence 73, which includes a fixed plate 76, a buffer plate 77 and a buffer spring 78. The fixed plate 76 is fixedly connected to the lower end of the first guardrail 71, and both ends of the buffer spring 78 are detachably connected to the buffer plate 77 and the fixed plate 76 respectively.

The speed sensor 5 is installed at the lower end of the first guardrail 71, and the alarm component is installed on the sliding car body 21. The speed sensor 5 and the alarm component are both connected to the controller for communication.

The absorber connecting plate 81 is installed on the sliding vehicle body 21, and the two ends of the vibration absorbing spring 82 are detachably connected to the absorber connecting plate 81 and the upper end of the side of the traction rope 3 respectively.

[0053] like Figure 1 and Figure 4 As shown, there are multiple friction plates 14 , and all of the multiple friction plates 14 are in contact with the conveyor belt 13 .

[0054] like Figure 4 As shown, the belt transmission mechanism 1 further includes a pulley 11 and a pulley 2 12 , and the pulley 1 11 and the pulley 2 12 are both in contact with the inner side surface of the conveyor belt 13 .

[0059] Working principle of automatic feeding mechanism for CDQ furnace:

[0060] The pulley 1 11 and the pulley 2 12 of the belt transmission mechanism 1 rotate, driving the sliding car 2 to move upward. When the sliding car 2 moves to the specified position above, the position sensor sends a signal to the controller, and the controller sends a signal to the drive motor, and the drive motor stops running. At this time, the coke tank 4 is located directly above the dry quenching furnace to be fed. At this time, the controller controls the coke tank 4 to release the raw material. After the release is completed, the tension on the tension sensor is reduced, and the tension sensor sends a signal to the controller. The controller sends a signal to the cylinder pump, and the cylinder pump controls the telescopic cylinder 62 to extend and press against the side of the sliding car 2. Since the angle between the length direction of the belt transmission mechanism 1 and the horizontal plane is equal to the friction angle, only a small force is required to ensure that the sliding car 2 slides down smoothly, saving electric energy. There is no need to start the pulley 11 and the pulley 2 12 again to reverse, and since the coke tank 4 has released the raw material, the impact energy after sliding down is small.
