Description

Technical Field

[0001] This invention belongs to the technical field of coke oven equipment, specifically relating to a dust collection system for a coke receiving and quenching car. Background Technology

[0002] The coking process in a horizontal heat recovery coke oven is completed using a coke receiving and quenching car. During coking, the car travels on the coke-side track, and upon reaching the designated coke oven, it first receives the coke, then travels fully loaded with coke to the wet quenching tower. After quenching the coke, it is tilted and fed onto the cooling platform. Dust is generated during the coking process, and if it is not effectively collected, it will pollute the environment. Summary of the Invention

[0003] To address some or all of the technical problems existing in the prior art, the present invention provides a coke quenching car dust collection system. The coke quenching car includes: a tractor, a tie rod, and a coke hopper. The tie rod is fixedly installed on one side of the tractor's direction of movement, and the coke hopper is installed on the side of the tie rod away from the tractor. The collection system includes: a flatbed trailer, a dust collector, a transmission pipeline, a movable platform, and a dust collection hood. The flatbed trailer is connected to the rear of the tractor. The dust collector is installed on the flatbed trailer. The movable platform is located above the coke hopper and the tie rod. The dust collection hood is installed on the movable platform and moves on the movable platform. The two ends of the transmission pipeline are respectively connected to the dust collector and the dust collection hood.

[0004] Furthermore, a spark arrester is also installed at the inlet of the dust collector.

[0005] Furthermore, the transmission pipeline includes: a fixed ventilation pipe, a movable ventilation pipe, a connecting pipe, and an exhaust pipe. The fixed ventilation pipe is fixedly connected to the inlet of the dust collector. The first end of the movable ventilation pipe is fitted inside the fixed ventilation pipe. The connecting pipe has a T-shaped structure and its vertical end is fixedly connected to the second end of the movable ventilation pipe. The exhaust pipe has two sets respectively located on the front and rear sides of the dust collection hood, and the first end of the exhaust pipe is fixedly connected to the dust collection hood. The second ends of the two sets of exhaust pipes are respectively fitted inside the two horizontal ends of the connecting pipe.

[0006] Furthermore, the active platform includes: track one, track two, and a traction assembly. Track one is fixedly installed on the coke receiving hopper, track two is fixedly installed on the pull rod, and the traction assembly is connected to the dust collection hood and driven by a sprocket and chain assembly mounted on the pull rod.

[0007] The dust collection system for the coke receiving and quenching car of the present invention has the following advantages and beneficial effects: By setting up the dust collection hood, dust can be adsorbed during coke receiving and transportation, preventing dust from escaping into the air and polluting the environment. The mobile platform enables the dust collection hood to move horizontally, allowing it to be close to the furnace mouth and improving its dust adsorption capacity. At the same time, when the coke receiving hopper is tilted, the dust collection hood can be moved away from the top of the coke receiving hopper to avoid interference. Attached Figure Description

[0010] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0011] like Figure 1-5 As shown, the coke quenching car dust collection system provided by the present invention includes: a tractor 1, a pull rod 2, and a coke receiving hopper 3. The pull rod 2 is fixedly installed on one side of the tractor 1 in the direction of movement, and the coke receiving hopper 3 is installed on the side of the pull rod 2 away from the tractor 1. The collection system includes: a flatbed trailer 4, a dust collector 5, a transmission pipe 6, a movable platform 7, and a dust collection hood 8. The flatbed trailer 4 is connected to the rear side of the tractor 1. The dust collector 5 is installed on the flatbed trailer 4. The movable platform 7 is located above the coke receiving hopper 3 and the pull rod 2. The dust collection hood 8 is installed on the movable platform 7 and moves on the movable platform 7. The two ends of the transmission pipe 6 are respectively connected to the dust collector 5 and the dust collection hood 8.

[0012] Before coke receiving, when the coke receiving and quenching car reaches the coke receiving position, the dust collection hood 8 is controlled to stay above the coke receiving hopper 3. As the coke receiving hopper 3 moves back and forth to receive coke, the dust collection hood 8 is driven by the coke receiving hopper 3 and moves synchronously with the coke receiving hopper 3 towards the furnace mouth, forming a closed space to collect smoke and dust. When the coke receiving and quenching car moves towards the quenching tower after coke receiving is completed, the dust collection hood 8 always stays above the coke receiving hopper 3, preventing the dust generated by the coking coal in the coke receiving hopper 3 from escaping into the air and causing environmental pollution during transportation. When the coke receiving and quenching car reaches the bottom of the quenching tower, the dust collection hood 8 is controlled to move above the pull rod 2, thereby exposing the coke receiving hopper 3 for easy quenching. After quenching is completed, the quenched coke is tilted onto the coke drying platform by tilting the coke receiving hopper 3.

[0013] By setting up the dust collection hood 8, dust can be adsorbed during coke receiving and transportation, preventing dust from escaping into the air and polluting the environment. The setting of the moving platform enables the dust collection hood 8 to move on a horizontal plane, allowing it to get close to the furnace mouth and improving its dust adsorption capacity. At the same time, when the coke receiving hopper 3 is tilted, the dust collection hood 8 can move away from the top of the coke receiving hopper 3 to avoid interference.

[0014] Furthermore, a spark arrester 9 is also provided at the inlet of the dust collector 5.

[0015] By setting up the spark arrester 9, sparks in the adsorbed dust can be captured, preventing sparks from entering the dust collector 5 and causing malfunctions or damage to the dust collector 5 (such as the filter bag being damaged by high temperature). This effectively improves the safety of the dust collector 5 and extends its service life.

[0016] Furthermore, the transmission pipe 6 includes: a fixed ventilation pipe 601, a movable ventilation pipe 602, a connecting pipe 603, and an exhaust pipe 604. The fixed ventilation pipe 601 is fixedly connected to the inlet of the dust collector 5. The first end of the movable ventilation pipe 602 is fitted inside the fixed ventilation pipe 601. The connecting pipe 603 has a T-shaped structure and its vertical end is fixedly connected to the second end of the movable ventilation pipe 602. The exhaust pipe 604 is provided with two sets respectively located on the front and rear sides of the dust collection hood 8, and the first end of the exhaust pipe 604 is fixedly connected to the dust collection hood 8. The second ends of the two sets of exhaust pipes are respectively fitted inside the two horizontal ends of the connecting pipe 603.

[0017] By combining the movable ventilation pipe 602 with the fixed ventilation pipe 601, the pipes are kept connected in the left-right direction (i.e., the direction of movement from the pull rod 2 to the coke hopper 3). By combining the two sets of air outlet pipes 604 and the connecting pipe 603, the pipes are kept connected in the front-back direction (i.e., the direction of movement from the coke hopper 3). This ensures that the transmission pipe 6 remains stable regardless of the movement of the dust collection hood 8, preventing the transmission pipe 6 from getting stuck or pulled out and causing dust to escape.

[0018] Furthermore, the active platform 7 includes: track one 701, track two 702 and traction component 703. Track one 701 is fixedly installed on the coke receiving hopper 3, track two 702 is fixedly installed on the pull rod 2, and the traction component 703 is connected to the dust collection hood 8 and is driven by the sprocket and chain assembly 10 provided on the pull rod 2.

[0019] Specifically, the traction component 703 is connected to the sprocket and chain assembly 10, and the traction component 703 is provided with a connecting hook. The side wall of the dust collection hood 8 is provided with a connecting groove in the front-back direction. The connecting hook slides in the connecting groove, thereby realizing that the dust collection hood 8 is driven to move in the left-right direction by the traction component 703 without interfering with the movement of the dust collection hood 8 in the front-back direction, thus improving the smoothness of the movement of the dust collection hood 8.
