Description

Technical Field

[0001] This utility model relates to the field of coke oven technology, and in particular to an automatic opening and closing device for the water seal cover of the coke oven riser pipe. Background Technology

[0002] In the coke oven production process, the opening and closing of the riser pipe water seal cover and flap valve is required for each batch of coke produced. This is generally done manually. Each time the riser pipe water seal cover and flap valve are opened and closed, raw coal gas leaks, generating VOC emissions. The coke oven is a non-pressurized system constructed of refractory bricks. If the pressure exceeds the limit, the water seal cover will automatically open using the pressure principle to protect the furnace walls.

[0003] The water seal cover of the coke oven riser pipe needs to be opened and closed to ensure a tight seal. However, the existing opening and closing devices for the riser pipe water seal cover cannot achieve a better sealing effect. Therefore, there is an urgent need for an automatic opening and closing device for the coke oven riser pipe water seal cover to solve the above problems. Utility Model Content

[0004] To solve the above problems, this utility model provides an automatic opening and closing device for the water seal cover of the coke oven riser pipe. This utility model is achieved through the following technical solution.

[0005] An automatic opening and closing device for a water seal cover on a coke oven riser pipe includes a coke oven pipe, the top of which is covered with a fixed cover. An opening and closing mechanism is provided on the outer surface of the coke oven pipe, the opening and closing mechanism comprising:

[0006] A fixed base, the top of which is fixedly connected to a support frame and a sliding rod;

[0007] A curved extrusion arm, with a fixed rod running through it. Springs are fixedly connected to both ends of the fixed rod. A push-pull frame is rotatably connected to one end of the curved extrusion arm. A connecting rod is fixedly connected to the bottom end of the push-pull frame. A lifting lug is fixedly connected to one end of the connecting rod.

[0008] A servo motor is fixedly connected to a fixed base. The lead screw fixed to the output shaft of the servo motor is rotatably connected to the fixed base. One end of the lead screw is provided with a movable seat, and the movable seat is threadedly engaged with the lead screw.

[0009] Furthermore, the curved extrusion arm is rotatably connected to the support frame, and the other end of the curved extrusion arm is fixedly connected to the center position of the top of the fixed cover.

[0010] Furthermore, one end of each of the two springs is fixedly connected to the push-pull bracket.

[0011] Furthermore, the movable seat is rotatably connected to the lifting lug via a set shaft, and the movable seat is movably connected to the slide rod.

[0012] Furthermore, a rubber sealing ring is provided at the bottom of the fixed cover, and the coke oven pipe is sealed to the fixed cover through the rubber sealing ring.

[0013] Furthermore, the outer surface of the fixing base is provided with mounting holes.

[0014] The beneficial effects of this invention are that, during operation, the servo motor drives the lead screw to rotate, which in turn drives the threaded movable seat to rise and fall on the slide rod. When the movable seat descends, the lifting lug connected to the movable seat pulls the connecting rod, which in turn pulls the push-pull frame downwards. The push-pull frame then pulls the curved extrusion arm to rotate clockwise on the support frame. The clockwise rotation of the curved extrusion arm pulls the fixed cover away from the top of the coke oven pipe, allowing the fixed cover to open from the coke oven pipe. Conversely, when the movable seat rises, it can... The curved extrusion arm can be driven to rotate counterclockwise. The counterclockwise rotation of the curved extrusion arm can push the fixed cover onto the top of the coke oven pipe. When the curved extrusion arm rotates clockwise, the spring returns to its original position. When the curved extrusion arm rotates counterclockwise, the push-pull bracket, together with the fixed cover, compresses and stores energy in the spring. After storing energy, it generates a reaction force, which can apply a reverse extrusion force to the fixed cover, so that the coke oven pipe has a better sealing effect between the rubber sealing ring and the fixed cover. The structure is simple, easy to install, and easy to automatically control the opening and closing, which can improve the sealing effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-3 As shown, the present invention has the following specific embodiments.

[0027] Example:

[0028] An automatic opening and closing device for a water seal cover on a coke oven riser pipe includes a coke oven pipe 1, a fixed cover 2 covering the top of the coke oven pipe 1, and an opening and closing mechanism provided on the outer surface of the coke oven pipe 1. The opening and closing mechanism includes:

[0029] The fixed base 3 has a support frame 31 and a slide rod 32 fixedly connected to its top;

[0030] A curved extrusion arm 4 is connected through a fixed rod 41. Both ends of the fixed rod 41 are fixedly connected to springs 411. One end of the curved extrusion arm 4 is rotatably connected to a push-pull frame 42. The bottom end of the push-pull frame 42 is fixedly connected to a connecting rod 421. One end of the connecting rod 421 is fixedly connected to a lifting lug 422.

[0031] Servo motor 5 is fixedly connected to fixed base 3. The lead screw 51, which is fixed to the output shaft of servo motor 5, is rotatably connected to fixed base 3. One end of lead screw 51 is provided with movable seat 52, and movable seat 52 is threadedly engaged with lead screw 51.

[0032] Specifically, the curved extrusion arm 4 is rotatably connected to the support frame 31, and the other end of the curved extrusion arm 4 is fixedly connected to the center position of the top of the fixed cover 2.

[0033] Specifically, one end of each of the two springs 411 is fixedly connected to the push-pull bracket 42.

[0034] Specifically, the movable seat 52 is rotatably connected to the lifting lug 422 via a set shaft, and the movable seat 52 is movably connected to the slide rod 32.

[0035] Specifically, a rubber sealing ring 21 is provided at the bottom of the fixed cover 2, and the coke oven pipe 1 is sealed with the fixed cover 2 through the rubber sealing ring 21.

[0036] Specifically, mounting holes are provided on the outer surface of the mounting base 3.

[0037] The working principle of this utility model:

[0038] When using the device, turning on the servo motor 5 drives the lead screw 51 to rotate. The lead screw 51 drives the threaded movable seat 52 to rise and fall on the slide rod 32. When the movable seat 52 falls, the movable seat 52 pulls the connecting rod 421 through the rotating lifting lug 422. The connecting rod 421 pulls the push-pull frame 42 downward. The push-pull frame 42 pulls the curved extrusion arm 4 to rotate clockwise on the support frame 31. The clockwise rotating curved extrusion arm 4 can pull the fixed cover 2 away from the top of the coke oven pipe 1. At this time, the fixed cover 2 can be opened between the fixed cover 2 and the coke oven pipe 1. Conversely, when the movable seat 52 rises, the movable seat 52... The curved extrusion arm 4 can be driven to rotate counterclockwise. The counterclockwise rotating curved extrusion arm 4 can push the fixed cover 2 to cover the top of the coke oven pipe 1. When the curved extrusion arm 4 rotates clockwise, the spring 411 returns to its original position. When the curved extrusion arm 4 rotates counterclockwise, the push-pull bracket 42, together with the fixed cover 2, will compress and store energy in the spring 411. After storing energy, it will produce a reaction force, thereby applying a reverse extrusion force to the fixed cover 2, so that the coke oven pipe 1 has a better sealing effect between the rubber sealing ring 21 and the fixed cover 2. The structure is simple, easy to install, and easy to automatically control the opening and closing, and can achieve a sealing effect.
