Description

Technical Field

[0001] This utility model relates to the field of coke unloading technology, specifically to a coke scraping device. Background Technology

[0002] A coke oven is an industrial furnace used for the dry distillation of coal. It primarily heats coal to high temperatures in the absence of air, causing a thermal decomposition reaction that produces coke, coal gas, and various chemical products. Coke pushing is a crucial step in the coke oven production process. After the coal has undergone a certain coking time in the carbonization chamber and completed the dry distillation process to form coke, a coke pusher is used to push the coke out to make room for the next round of coal charging. This ensures continuous and stable production of the coke oven and guarantees the smooth operation of the entire coking process.

[0003] However, in actual operation, coke oven carbonization chambers often face difficulties in pushing coke. The main reason for this difficulty is usually the high friction between the coke and the inner wall of the carbonization chamber. Many factors contribute to this increased friction, such as: excessively long coking time, insufficient coking time, uneven heating of the coke oven, damage to the inner wall of the carbonization chamber, and excessive graphite growth on the inner wall. If a coke pusher is used to forcibly push the coke out of the carbonization chamber under these conditions, it can easily cause the pushing current to exceed the limit, posing a risk of burning out the motor, damaging the pushing rod and the vehicle, and damaging the inner wall of the carbonization chamber.

[0004] To address this issue, existing technologies employ a coke-scraping method, which involves using a shovel to remove the portion of the coke that is obstructing the coke pushing process, reducing friction between the coke and the inner wall of the carbonization chamber before pushing the coke with a coke pusher. However, for coke with high hardness and a dense structure, traditional coke-scraping shovels are ineffective at breaking and separating it, resulting in an unsmooth coke-scraping process and low efficiency. Utility Model Content

[0005] To address the technical problem that traditional coke scraping shovels are ineffective in breaking and separating coke with high hardness and dense structure, resulting in an unsmooth coke scraping process and low scraping efficiency, this utility model provides a coke scraping device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A coke-removing device includes a coke-removing shovel, which includes a base plate, side plates perpendicularly arranged on opposite sides of the base plate, and a vertical plate perpendicularly arranged on one side of the base plate, the vertical plate being perpendicular to both side plates; a reinforcing plate parallel to the base plate is provided between the two side plates, and the side edge of the base plate away from the vertical plate is serrated.

[0008] The above structural design uses a base plate, two side plates, and a vertical plate to form a space capable of holding coke. The sides of the base plate are serrated, allowing the coke-scraping shovel in this invention to cut into the coke like a saw when dealing with hard, dense coke, compared to a traditional flat-edged shovel. This effectively breaks and separates the coke, reduces scraping resistance, and significantly improves scraping efficiency. The side of the vertical plate away from the side plates can be connected to the push rod of the coke pusher, allowing the push rod to reciprocate and drive the coke-scraping shovel in and out of the carbonization chamber, thus cleaning the coke out of the carbonization chamber sequentially.

[0009] As a preferred implementation of the coke removal device, the side of the reinforcing plate away from the vertical plate is serrated.

[0010] By adopting the above structural design, the side of the reinforcing plate furthest from the vertical plate is serrated, forming a double crushing structure with the serrated side of the base plate. During coke removal, the reinforcing plate and the base plate can crush the coke from different heights, further enhancing the coke removal shovel's ability to crush hard coke and improving removal efficiency. The reinforcing plate itself enhances the structural strength of the coke removal shovel, and the serrated design does not weaken its strength; the reinforcing plate can still maintain good crushing performance under high pressure.

[0011] As a preferred implementation of the coke removal device, there are two reinforcing plates, and the distances between the two reinforcing plates and the vertical plate are different. The distance between the reinforcing plate closer to the vertical plate and the bottom plate is H, and the distance between the other reinforcing plate and the bottom plate is L, where H > L.

[0012] The above structural design incorporates two reinforcing plates of different heights. First, these plates can accommodate coke at varying heights within the carbonization chamber, applying appropriate crushing force to coke at different locations during the advancement process, thereby improving the efficiency and effectiveness of coke removal. Second, the different heights of the reinforcing plates help optimize the force distribution on the coke removal shovel during the removal process, resulting in a more uniform force distribution and reducing the risk of damage due to excessive localized stress, thus extending the service life of the coke removal shovel.

[0013] As a preferred implementation of the slag removal device, at least one side plate has a blade on its inner wall. The blade is arranged parallel to the bottom plate, and the back of the blade is connected to the inner wall of the side plate.

[0014] With the above structural design, the horizontal blade installed on the inner wall of the side plate can laterally cut the coke in contact with the side plate during the advance of the coke scraper, further dividing large pieces of coke into smaller pieces, reducing the overall strength and resistance of the coke, and making the coke scraping process smoother. At the same time, the blade works in conjunction with the saw teeth of the bottom plate to crush the coke from different directions, greatly improving the ability to crush hard and dense coke.

[0015] As a preferred implementation of the descaling device, the side of the blade furthest from the vertical plate is a pointed blade head.

[0016] By adopting the above structural design, on the one hand, the pointed blade makes it easier for the first blade to cut into the coke, especially for coke with a relatively hard surface, which can quickly destroy its surface structure, reduce the coke's cutting resistance, and improve cutting efficiency. On the other hand, the pointed blade generates less resistance during the coke cutting process, which helps the first blade move more smoothly in the coke, reducing energy consumption and wear during the coke scraper's advance.

[0017] As a preferred implementation of the coke removal device, the upper surface of the base plate is provided with several blades two perpendicular to the base plate, and the back of the blades two is connected to the upper surface of the base plate.

[0018] With the above structural design, several blades are vertically arranged on the upper surface of the base plate. When the coke scraper moves forward, it can longitudinally and multi-pointly crush the coke below, making the coke easier to separate and remove.

[0019] As a preferred implementation of the descaling device, the side of the second blade away from the vertical plate is a pointed blade head.

[0020] By adopting the above structural design, the bi-pointed blade enhances its ability to cut and crush the coke below, especially against coke layers with higher hardness, enabling more effective crushing of the coke and reducing the resistance of the coke scraper. On the other hand, when crushing coke, the pointed blade can concentrate most of the force on the blade head, reducing direct wear of the coke on the bottom plate, protecting the bottom plate, and extending the overall service life of the coke scraper.

[0021] As a preferred implementation of the coke removal device, a coke removal port is opened on the side plate, and a movable plate is installed inside the coke removal port. The movable plate is hinged to the side plate. A U-shaped limiting plate is connected to the outer wall of the side plate. A limiting hole is formed between the limiting plate and the outer wall of the side plate. The axial direction of the limiting hole is perpendicular to the bottom plate. A pin is inserted into the limiting hole. A stop bar is vertically connected to the top of the pin. The bottom end of the pin extends to the movable plate.

[0022] With the above structural design, the movable plate can be opened by pulling out the pin, making it easy to remove the coke fragments and debris accumulated inside the coke scraper. This prevents coke residue from affecting the next coke scraping operation and reduces cleaning workload and time. When the pin is inserted into the limiting hole, the bottom end of the pin blocks the opening of the movable plate, thus keeping the coke cleaning port closed during the coke scraping process and preventing coke from leaking while scraping.

[0023] As a preferred implementation of the coke removal device, the two sides of the upright plate are welded with connecting plates parallel to the side plate. The connecting plates are attached to the outer wall of the side plate and are connected to the side plate by bolts. The top of the upright plate and the connecting plates extend beyond the top of the side plate.

[0024] The above structural design, with its bolted connection, facilitates the installation, disassembly, and maintenance of the coke scraper. The tops of the upright plate and connecting plate extend beyond the tops of the side plates, which increases the volume of the coke scraper.

[0025] As a preferred implementation of the coke removal device, the side plate includes a rectangular part and a right-angled triangular part in sequence from the direction close to the vertical plate to the direction far away from the vertical plate. The rectangular part is connected to the connecting plate by bolts, and one right-angled side of the right-angled triangular part is connected to the rectangular part, and the other right-angled side is connected to the bottom plate.

[0026] The above-mentioned structural design, with its rectangular and right-angled triangular sections on the side plates, can better transmit and disperse the forces experienced by the coke scraper during the scraping process. This makes the overall structure of the coke scraper more rationally stressed, reduces stress concentration, and improves the structural strength and service life of the coke scraper.

[0027] The beneficial effects of this utility model include:

[0028] The bottom plate of the coke scraper has serrated sides. Compared with traditional flat-mouthed scrapers, when facing coke with high hardness and dense structure, the coke scraper of this utility model can cut into the coke like a saw, effectively breaking and separating it, reducing the resistance to scraping coke, and significantly improving the efficiency of scraping coke.

[0036] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Reference Figure 1-4 This embodiment proposes a coke-removing device, including a coke-removing shovel. The shovel includes a base plate 1, with side plates 2 vertically arranged on opposite sides of the base plate 1. A vertical plate 3 is vertically arranged on one side of the base plate 1, perpendicular to both side plates 2. Connecting plates 12 parallel to the side plates 2 are welded to both sides of the vertical plate 3. The connecting plates 12 are attached to the outer wall of the side plates 2 and connected to the side plates 2 by bolts 13. The tops of the vertical plate 3 and the connecting plates 12 extend beyond the tops of the side plates 2. The base plate 1, the two side plates 2, and the vertical plate 3 form a space capable of accommodating coke. The side plates 2, from near the vertical plate 3 to away from the vertical plate 3, sequentially include a rectangular portion 21 and a right-angled triangular portion 22. The rectangular portion 21 is connected to the connecting plate 12 by bolts 13. One right-angled side of the right-angled triangular portion 22 is connected to the rectangular portion 21, and the other right-angled side is connected to the base plate 1. The right-angled triangular side plate 2 can better transmit and disperse the force received by the coke scraper during the coke scraping process, making the structure of the entire coke scraper more reasonable, reducing stress concentration, and improving the structural strength and service life of the coke scraper.

[0038] Between the two side plates 2, there is a reinforcing plate 4 that is parallel to the bottom plate 1. There are two reinforcing plates 4, and the distances between the two reinforcing plates 4 and the upright plate 3 are different. The distance between the reinforcing plate 4 that is closer to the upright plate 3 and the bottom plate 1 is H, and the distance between the other reinforcing plate 4 and the bottom plate 1 is L, where H > L.

[0039] The side of the reinforcing plate 4 away from the vertical plate 3 is serrated, and the side of the bottom plate 1 away from the vertical plate 3 is also serrated. The serrated sides of the reinforcing plate 4 and the bottom plate 1 form a double crushing structure, which allows the reinforcing plate 4 and the bottom plate 1 to crush the coke from different heights during coke removal.

[0040] The inner wall of the side plate 2 is equipped with a blade 5, which is parallel to the bottom plate 1. The back of the blade 5 is connected to the inner wall of the side plate 2. The side of the blade 5 away from the vertical plate 3 has a pointed tip. During the advance of the coke scraper, the blade 5 can laterally cut the coke in contact with the side plate 2, further dividing large pieces of coke into smaller pieces, reducing the overall strength and resistance of the coke, and making the coke scraping process smoother.

[0041] The upper surface of the base plate 1 is provided with several blades 2 6 perpendicular to the base plate 1, and the back of the blades 2 6 is connected to the upper surface of the base plate 1. The side of the blades 2 6 away from the vertical plate 3 is a pointed blade. When the coke scraper moves forward, the several blades 2 6 can longitudinally and multi-pointly crush the coke inside the lower part of the coke scraper, making the coke easier to separate and remove.

[0042] Blade 1 (5), Blade 2 (6), Reinforcing plate (4), and base plate (1) can form a multi-crushing structure, which can crush coke from different heights and angles, making the coke removal process smoother.

[0043] A coke-removing opening is provided on the side plate 2, and a movable plate 7 is installed inside the opening. The movable plate 7 is hinged to the side plate 2 via a hinge 15. A U-shaped limiting plate 8 is connected to the outer wall of the side plate 2, forming a limiting hole 9 between the limiting plate 8 and the outer wall of the side plate 2. The axial direction of the limiting hole 9 is perpendicular to the bottom plate 1. A pin 10 is inserted into the limiting hole 9, and a stop bar 11 is vertically connected to the top of the pin 10. The bottom end of the pin 10 extends to the movable plate 7. When it is necessary to clean the coke scraper, the pin 10 is pulled out, which opens the movable plate 7, making it convenient to clean the coke and debris inside the scraper through the opening. After cleaning, the movable plate 7 is closed, and the pin 10 is inserted back into the limiting hole 9. Since the bottom end of the pin 10 blocks the opening of the movable plate 7, the opening can be kept closed during the scraping process, preventing coke from leaking out while scraping.

[0044] The length of the coke scraper is determined by the actual distance between the push rod 14 of the coke pusher car and the oven door. The width of the coke scraper is determined by the width of the carbonization chamber, and the width of the coke scraper is smaller than the width of the carbonization chamber. Considering the elevation deviation of the bottom of each carbonization chamber and the deformation and sagging of the coke scraper, the bottom of the coke scraper should be 10-20mm higher than the bottom of the carbonization chamber.

[0045] Work process:

[0046] Securely connect the side of the upright plate 3 of the coke scraping device away from the side plate 2 to the bottom of the push rod 14 of the coke pusher. Start the coke pusher, and the push rod 14 drives the coke scraping shovel to extend into the carbonization chamber.

[0047] When the coke scraper comes into contact with the coke, the serrated side edge of the base plate 1 cuts into the coke first, like a saw, to initially break and separate the hard, dense coke, reducing scraping resistance. Simultaneously, blade 5 on the inner wall of the side plate 2 cuts the coke in contact with the side plate 2 laterally, dividing large pieces of coke into smaller pieces; blade 6, vertically positioned on the upper surface of the base plate 1, breaks the coke below the scraper longitudinally. Blades 5 and 6, working in conjunction with the base plate 1, break the coke from all directions, greatly reducing the overall strength and resistance of the coke, making the scraping process smoother and more efficient.

[0048] As the coke-removing shovel continues to advance, the side of the reinforcing plate 4 is also serrated, forming a multi-crushing structure with the serrations of the bottom plate 1, blade 5, and blade 6, which crushes the coke from different heights, further enhancing the crushing effect.

[0049] Next, push rod 14 is pulled back, causing the coke scraper to exit from the carbonization chamber. At this point, the coke scraper has already contained a certain amount of broken coke. After cleaning the coke from the coke scraper, the coke scraper is driven back into the carbonization chamber, and the above coke scraping action is repeated to gradually remove the coke from the carbonization chamber until the coke scraping task in the carbonization chamber is completed.

[0050] Each time the coke scraper is removed from the carbonization chamber or after the coke scraping operation is completed, the pin 10 inside the upper limit hole 9 of the side plate 2 can be pulled out, the movable plate 7 can be opened, and the coke, broken coke, and debris accumulated inside the coke scraper can be removed to prevent coke, broken coke, and debris residue from affecting the next coke scraping operation. After cleaning, the movable plate 7 can be closed again and the pin 10 can be inserted to fix it.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
