Description

Technical Field

[0001] This utility model relates to the field of coke oven smoke removal technology, and more specifically, to a smoke removal device for the mouth of a coke oven in coal coking production. Background Technology

[0002] In the coal coking production process, the coke oven, as the core production equipment, continuously generates a large amount of smoke and dust at its opening during coal charging, coke discharging and other operations. This smoke and dust contains a variety of pollutants such as dust, sulfides, nitrogen oxides and tar. If it is not treated in a timely and effective manner, it will not only permeate the production workshop and surrounding areas, but also cause a sharp decline in the air quality of the working environment.

[0003] Currently, coke oven dust treatment mostly adopts the traditional hood-type smoke removal structure, which simply sets up a fixed hood above the oven mouth and relies on natural ventilation or simple fans to introduce the dust into the exhaust pipe. However, this device lacks active guidance and efficient adsorption design for the dust, and the dust is prone to diffusion and retention inside the hood. Especially when the amount of dust generated at the coke oven mouth is large, a large amount of dust will escape from the edge of the hood, resulting in extremely low smoke removal efficiency, which cannot meet the smoke removal needs of actual production. Therefore, a smoke removal device for coke oven mouth in coal coking production has been designed. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a smoke removal device for the coke oven mouth in coal coking production, which has the advantage of optimized smoke removal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a smoke removal device for the mouth of a coke oven in coal coking production, comprising a smoke collection hood, a smoke removal pipe fixedly connected to the top of the smoke collection hood, a guide plate fixedly connected to the bottom of the smoke collection hood, a collection box provided on the inner wall of the guide plate, a smoke removal hood fixedly connected to the inner wall of the smoke collection hood, a rotating roller rotatably connected to the inner wall of the smoke removal hood, multiple spiral blades fixedly connected around the outer wall of the rotating roller, a brush plate fixedly connected to the outer wall of the spiral blades, a driving assembly provided at the top of the rotating roller, the driving assembly being used to drive the rotating roller to rotate, multiple smoke removal windows provided around the outer wall of the smoke removal hood, and a collection tray fixedly connected to the bottom of the smoke removal hood.

[0006] As a preferred embodiment of this utility model, a connecting ring is fixedly connected to the outer wall of the smoke collection hood, and lifting lugs are symmetrically fixedly connected to the outer wall of the connecting ring.

[0007] As a preferred embodiment of this utility model, the bottom of the smoke hood is provided with a leakage hole, the bottom end of the collection tray is fixedly connected to a collection pipe, and the output end of the collection pipe is fixedly connected to the top end of the collection box.

[0008] As a preferred embodiment of this utility model, a rotating rod is fixedly connected to the inner wall of the rotating roller, and the bottom end of the rotating rod is rotatably connected to the inner wall of the smoke hood.

[0009] As a preferred embodiment of this utility model, the driving assembly includes a connecting frame fixedly connected to the inner wall of the smoke collection hood, the top end of the rotating rod extending into the inner wall of the connecting frame, and a transmission wheel fixedly connected to the extended end of the rotating rod.

[0010] As a preferred embodiment of this utility model, the inner wall of the connecting frame is rotatably connected to a drive shaft, the outer wall of the drive shaft is fixedly connected to a drive wheel, and a transmission belt is used to drive the drive wheel and the transmission wheel.

[0011] As a preferred embodiment of this utility model, a motor is fixedly connected to the top of the connecting frame, the top of the drive shaft extends out of the outer wall of the connecting frame, and the extended end of the drive shaft is fixedly connected to the output end of the motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Compared with traditional devices, this utility model is equipped with a guide plate and a smoke hood. When the smoke and dust emitted from the coke oven rises into the inner wall of the smoke hood, it can flow stably to the bottom of the smoke hood under the guidance of the guide plate, avoiding the spread or retention of smoke and dust in the smoke hood. The operator can start the drive motor to drive the drive shaft, drive wheel, transmission belt and transmission wheel linkage, drive the rotating rod, rotating roller and smoke hood to rotate, so that the airflow around the smoke hood forms a spiral upward trend. This spiral airflow can generate a stronger adsorption force, quickly engulfing the smoke and dust into the inner wall of the smoke hood. This not only accelerates the flow speed of the smoke and dust, but also covers multiple areas of the inner wall of the smoke hood, reducing smoke and dust residue and reducing the concentration of smoke and dust in the coke oven working environment.

[0013] 2. Compared with traditional devices, this utility model is equipped with a spiral blade, a brush plate, and a collection tray. While the rotating roller drives the smoke extraction window to remove smoke and dust, it also drives the spiral blade to rotate synchronously. The brush plate on the outer wall of the spiral blade scrapes the inner wall of the smoke extraction hood and the smoke extraction window, which can promptly remove the tar adhering to the inner wall of the equipment and prevent the smoke extraction window or smoke extraction pipe from being blocked by tar, thus affecting the efficiency of smoke and dust collection. The scraped tar flows into the collection box through the collection tray, the leakage hole at the bottom of the smoke extraction hood, and the collection pipe for centralized collection, which facilitates subsequent unified treatment and recycling, and further reduces the cost of waste disposal.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a smoke removal device for the mouth of a coke oven in coal coking production, including a smoke collection hood 1, a smoke removal pipe 4 fixedly connected to the top of the smoke collection hood 1, a guide plate 5 fixedly connected to the bottom of the smoke collection hood 1, a collection box 18 provided on the inner wall of the guide plate 5, a smoke removal hood 6 fixedly connected to the inner wall of the smoke collection hood 1, a rotating roller 8 rotatably connected to the inner wall of the smoke removal hood 6, a plurality of spiral blades 9 fixedly connected around the outer wall of the rotating roller 8, a brush plate 901 fixedly connected to the outer wall of the spiral blades 9, a driving assembly provided at the top of the rotating roller 8, the driving assembly being used to drive the rotating roller 8 to rotate, a plurality of smoke removal windows 7 being arranged around the outer wall of the smoke removal hood 6, and a collection tray 16 fixedly connected to the bottom of the smoke removal hood 6.

[0018] It should be noted that the spiral blade 9 adopts a design that is wider at the top and narrower at the bottom. At the same time, the surface of the spiral blade 9 is provided with a curved arc. This design allows the spiral blade 9 to attract smoke and dust to the top when it rotates, thus achieving smooth conveying of smoke and dust.

[0019] Among them, the outer wall of the smoke hood 1 is fixedly connected to the connecting ring 3, and the outer wall of the connecting ring 3 is symmetrically fixedly connected to the lifting lug 2.

[0020] It should be noted that the operator can connect to the inner wall of the lifting lug 2 with a rope, and then use the rope and lifting equipment to lift the lifting lug 2 and the smoke hood 1 and move them above the smoke outlet of the coke oven to carry out smoke removal work.

[0021] The smoke hood 6 has a drain hole 601 at the bottom, and a collection pipe 17 is fixedly connected to the bottom of the collection tray 16. The output end of the collection pipe 17 is fixedly connected to the top of the collection box 18.

[0022] It should be noted that the collection tray 16 is used to collect tar. The tar will drip from the surface of the drain hole 601 and the smoke hood 6 onto the inner wall of the collection tray 16. Then, the tar will flow from the collection tray 16 to the inner wall of the collection box 18 through the collection pipe 17 for collection.

[0023] The inner wall of the rotating roller 8 is fixedly connected to a rotating rod 10, and the bottom end of the rotating rod 10 is rotatably connected to the inner wall of the smoke hood 6.

[0024] It should be noted that a bearing seat is provided on a small surface of the inner wall of the smoke hood 6. The inner wall of the bearing seat is rotatably connected to the bottom end of the rotating rod 10. The bearing seat supports the rotating rod 10 to drive the rotating roller 8 and the spiral blade 9 to rotate. The drive assembly includes a connecting frame 11 fixedly connected to the inner wall of the smoke hood 1, the top end of the rotating rod 10 extending into the inner wall of the connecting frame 11, and a transmission wheel 12 fixedly connected to the extended end of the rotating rod 10.

[0025] The inner wall of the connecting frame 11 is rotatably connected to a drive shaft 1401, the outer wall of the drive shaft 1401 is fixedly connected to a drive wheel 14, and a transmission belt 13 is connected between the drive wheel 14 and the transmission wheel 12.

[0026] The top of the connecting frame 11 is fixedly connected to the motor 15, and the top of the drive shaft 1401 extends out of the outer wall of the connecting frame 11. The extended end of the drive shaft 1401 is fixedly connected to the output end of the motor 15.

[0027] It should be noted that the motor 15 is based on the servo motor model SGM7G-09AFC6C. The operator can drive the rotating rod 10 to rotate by driving the motor 15. When the motor 15 passes, it drives the drive shaft 1401 and the drive wheel 14 to rotate through the output end. Then, the drive wheel 14 drives the transmission wheel 12 to rotate through the transmission belt 13, thereby driving the rotating rod 10 and the rotating roller 8 to rotate.

[0028] Working principle and usage process of this utility model: In specific operation, the operator needs to connect to the inner wall of the lifting lug 2 with a rope, and lift the lifting lug 2 together with the connecting ring 3 and the smoke hood 1 with a lifting tool. The smoke hood 1 is then hoisted to the smoke outlet of the coke oven. When the coke oven is working and emitting smoke and dust, the smoke and dust will rise into the inner wall of the smoke hood 1 and flow down to the bottom of the smoke removal hood 6 through the guide plate 5.

[0029] When the smoke flows to the top of the smoke hood 6, the operator can remove the smoke and dust by driving the motor 15. After the motor 15 starts, it will drive the drive shaft 1401 to rotate on the inner wall of the connecting frame 11 through the output end. Then, the drive shaft 1401 will drive the drive wheel 14 to rotate. The rotation of the drive wheel 14 will drive the transmission wheel 12 to rotate through the transmission connection with the transmission belt 13. Thus, the transmission wheel 12 will drive the rotating rod 10 and the rotating roller 8 to rotate on the inner wall of the smoke hood 6. The rotating roller 8 will further drive the surrounding smoke removal windows 7 to rotate. The rotation of the smoke removal windows 7 will drive the surrounding airflow to form a spiral upward movement trend, so that the smoke and dust will be drawn into the inner wall of the smoke removal pipe 4 through the multiple smoke removal windows 7 on the outer wall of the smoke hood 6, thereby optimizing the flow direction of the smoke and dust. Finally, the smoke and dust will be effectively collected through the smoke removal pipe 4.

[0030] When the rotating roller 8 drives the spiral blade 9 to rotate, the spiral blade 9 can clean the tar from the inner wall of the smoke hood 6. When the spiral blade 9 rotates, it will drive the brush plate 901 on the outer wall to rotate synchronously. The brush plate 901 will scrape off the tar from the inner wall of the smoke hood 6 and the smoke window 7 by rotating. The scraped tar will fall onto the inner wall of the collection tray 16, or flow down the inner wall of the smoke hood 6 to the bottom. The bottom of the smoke hood 6 is provided with a drain hole 601. Finally, the tar will flow into the inner wall of the smoke hood 6 through the drain hole 601. The tar on the inner wall of the smoke hood 6 will finally flow into the inner wall of the collection box 18 through the collection pipe 17 for collection.
