Description

Technical Field

[0001] This utility model relates to the technical field of semi-coke processing equipment, and in particular to a semi-coke coking device. Background Technology

[0002] A modern coke oven consists of a carbonization chamber, combustion chamber, regenerator, inclined flue zone, roof, foundation, and flue. In the carbonization chamber, coal is heated and transformed into coke under air-isolated conditions. A single coke oven has dozens of alternating carbonization and combustion chambers, separated by refractory materials. Each combustion chamber has 20-30 vertical flues. Preheated gas and air from the regenerator meet and burn at the bottom of the vertical flues, providing heat to the carbonization chamber from the side. The regenerator is located at the bottom of the coke oven, utilizing high-temperature waste gas to preheat the gas and air used for heating. The inclined flue zone connects the regenerator and combustion chambers. The furnace body above the carbonization and combustion chambers is called the roof, and its thickness is determined by the furnace body strength and the need to reduce the roof surface temperature. The roof zone has coal charging holes and riser holes leading to the carbonization chamber for charging coal and discharging the raw gas generated during coal dry distillation.

[0003] Traditional coke production technology mostly employs wet coking equipment, with the coke pusher frame housed in a large silo above a closed water basin. Because the semi-coke, heated to 500°C-600°C, is directly discharged into the water pool at the bottom of the furnace, the resulting large amount of steam effectively protects the coke pusher frame at a relatively low temperature. However, with the rapid development of low-moisture quenching technology, the original large water pool quenching at the furnace bottom has been replaced by water spray or steam quenching, inevitably leading to high temperatures in the quenching silo.

[0004] When cooling semi-coke, it is usually first pushed into a transport vehicle by a pusher plate, and then transported to a cooling tower for rapid cooling to form a finished product. The finished product is then directly piled up outdoors to air dry. This process is cumbersome, and the moisture evaporates slowly when the finished product is air dried outdoors, especially the semi-coke piled inside, which affects the processing efficiency of semi-coke. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a semi-coke coking device, which alleviates the problem of cumbersome procedures during semi-coke handling, increases the contact area between semi-coke and air, improves the evaporation rate of semi-coke, and enhances the processing efficiency of semi-coke.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model provides a semi-coke coking device, including an inclined coking component and a synchronous belt component. The coking component is used to tilt and convey the semi-coke to be transported upwards, and the synchronous belt component is used to horizontally transport the semi-coke to be transported that falls from the coking component. The coke output assembly includes a mounting frame, a first sprocket and a second sprocket rotatably connected to the mounting frame, a drive component connected to the first sprocket and the second sprocket, a plurality of support components mounted on the drive component, an inclined support plate, and a drive unit drivenly connected to the first sprocket. The line connecting the rotation centers of the support plate and the first sprocket and the second sprocket is parallel. When it is necessary to discharge the semi-coke to be transported, the drive unit drives the first sprocket to rotate. Under the action of the drive component and the second sprocket, the support component moves upward, causing the support component to push the semi-coke to be transported to move upward along the upper surface of the support plate until the semi-coke to be transported falls from the coking assembly onto the synchronous belt assembly.

[0007] It also includes a coke quenching tank, which is used to store semi-coke to be transported. The coke quenching tank is provided with a material guiding surface, which is connected to the bottom end of the upper surface of the support plate. The first sprocket is located above the second sprocket, and the second sprocket is located inside the coke quenching groove; When the support pushes the semi-coke to be transported upward, the semi-coke to be transported is moved from the guide surface to the upper surface of the support plate by the support.

[0008] The drive component includes several drive chain links and multiple drive scrapers connected between two adjacent drive chain links. The drive chain links are connected to a first sprocket and a second sprocket. The mounting frame is provided with transport grooves located on both sides of the support plate. The transport grooves are connected to the support plate. Both ends of the drive scrapers abut against the inner side of the transport grooves.

[0009] The mounting bracket is provided with an evaporation space, which connects the area between the top of the mounting bracket and the support plate.

[0010] The scraper is provided with a material discharge surface, which is inclined. When the semi-coke to be transported detaches from the support plate, it falls along the material drop surface to the synchronous belt assembly under the action of gravity.

[0011] The mounting frame is equipped with a discharge hopper, which is connected to the top of the support plate.

[0012] The drive scraper is equipped with a material collection trough. When the semi-coke to be transported moves upward along the support plate, the semi-coke to be transported is accumulated in the accommodating space formed by the material collection trough, the material drop surface, the upper surface of the support plate, and the transport trough.

[0013] The discharge hopper is equipped with an inclined discharge channel, the bottom of which faces the synchronous belt assembly. The discharge channel is used to transport semi-coke to be transported.

[0014] The beneficial effects of this utility model are: The continuous operation of tilting the coke outlet assembly upward and synchronous belt assembly horizontally transports the coke, replacing the traditional push plate transfer and multiple transfers by the transport vehicle, reducing intermediate links and alleviating the problem of cumbersome procedures when handling semi-coke; by transporting the semi-coke to be transported in batches, the contact area between the semi-coke and the air is increased, and the semi-coke can be air-dried during the transportation process, thereby increasing the evaporation rate of the semi-coke and improving the processing efficiency of semi-coke.

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and accompanying drawings. Specific embodiments of the present invention will be described below. It should be noted that, in order to provide a concise description of these embodiments, this specification cannot provide a detailed description of all features of the actual embodiments.

[0023] refer to Figures 1 to 6As shown, this utility model provides a semi-coke coking device, including an inclined coking assembly 1 and a synchronous belt assembly 2. The coking assembly 1 is used to inclinedly convey the semi-coke 01 to be transported upwards, and the synchronous belt assembly 2 is used to horizontally transport the semi-coke 01 to be transported that falls from the coking assembly 1. The coking assembly 1 includes a mounting frame 11, a first sprocket 12 and a second sprocket 13 rotatably connected to the mounting frame 11, a driving member 14 connected to the first sprocket 12 and the second sprocket 13, a plurality of support members 15 installed on the driving member 14, and an inclined... The set support plate 16 and drive unit 17 are driven and connected to the first sprocket 12. The line connecting the rotation centers of the support plate 16, the first sprocket 12 and the second sprocket 13 is parallel. When it is necessary to discharge the semi-coke 01, the drive unit 17 drives the first sprocket 12 to rotate. Under the action of the drive member 14 and the second sprocket 13, the drive member 15 is driven to move upward, so that the drive member 15 pushes the semi-coke 01 to be transported to move upward along the upper surface of the support plate 16 until the semi-coke 01 to be transported falls from the coking assembly 1 onto the synchronous belt assembly 2.

[0024] refer to Figure 1 , 2 As shown, in practical applications, the drive unit 17 uses a variable frequency motor or reducer. The first sprocket 12 and the second sprocket 13 on both sides are connected by a coupling to ensure the coaxiality of the rotation of the first sprocket 12 and the second sprocket 13. The coke discharge assembly 1 is provided with two sets of symmetrically arranged sprockets. Through the symmetrically arranged sprockets and the drive member 14, the two ends of the support member 15 are smoothly driven, so as to realize the smooth pushing of the support member 15 to the semi-coke 01 to be transported. The drive member 14 adopts a ring chain, such as a roller chain. The two ends of the drive member 14 are respectively sleeved on the first sprocket 12 and the second sprocket 13. The length and strength of the drive member 14 must meet the requirements of inclined conveying. The chain pitch is matched with the sprocket to ensure smooth transmission. The spacing of the support member 15 is adjusted according to the size and conveying volume of the semi-coke 01 to be transported. The height of the support member 15 is slightly greater than the stacking thickness of the semi-coke 01 to be transported to ensure effective pushing of the semi-coke 01 to be transported without leakage.

[0025] refer to Figure 2 , 3As shown, when the semi-coke 01 to be transported needs to be discharged, the drive unit 17 starts and drives the first sprocket 12 to rotate clockwise or counterclockwise. The specific rotation direction is determined according to the installation direction. Through the cooperation of the drive component 14 and the second sprocket 13, the support component 15 moves upward along the inclined direction with the drive component 14. During the movement, the support component 15 pushes the semi-coke 01 to be transported placed on the support plate 16, so that the semi-coke 01 to be transported slides upward along the upper surface of the support plate 16. Since the line connecting the support plate 16 and the rotation center of the sprocket is parallel, the movement trajectory of the support component 15 is consistent with that of the support plate 16, ensuring smooth material feeding. When the semi-coke to be transported 01 is pushed to the top of the coking assembly 1, due to gravity, the semi-coke to be transported 01 falls off the support 15 and onto the synchronous belt assembly 2. The synchronous belt assembly 2 starts to transport the semi-coke to be transported horizontally to the designated location, such as a cooling tower or storage area. During the entire transportation process of the semi-coke to be transported 01, the speed of the coking assembly 1 and the synchronous belt assembly 2 is synchronously controlled by the control system to avoid the semi-coke to be transported 01 from piling up or being interrupted. In terms of structural setting, the inclined setting of the coking assembly 1 realizes the lifting from a low position to a high position, and the synchronous belt assembly 2 ensures the continuity of horizontal transportation.

[0026] refer to Figure 1 , 3 As shown, in summary, the continuous operation of the coking assembly 1 tilting upward and the synchronous belt assembly 2 horizontally transporting replaces the traditional push plate transfer and multiple transfers by the transport vehicle, reducing intermediate links and alleviating the problem of cumbersome procedures when handling semi-coke. By transporting the semi-coke to be transported in batches, compared with the method mentioned in the background technology of dropping all the semi-coke onto the transport vehicle at once, the contact area between the semi-coke and the air is increased, and the semi-coke can be dried during transportation, thereby increasing the evaporation rate and improving the processing efficiency of semi-coke.

[0027] refer to Figure 1 , 2 As shown, this embodiment also includes a quenching trough 3, which is used to store semi-coke 01 to be transported. The quenching trough 3 is provided with a guide surface 31, which is connected to the bottom end of the upper surface of the support plate 16. The first sprocket 12 is located above the second sprocket 13, and the second sprocket 13 is located inside the quenching trough 3. In actual application, when the support member 15 pushes the semi-coke 01 to be transported upward, the semi-coke 01 to be transported is moved by the support member 15 from the guide surface 31 to the upper surface of the support plate 16. The guide surface 31 smoothly guides the semi-coke 01 to be transported to the support plate 16 for transport, which facilitates the stable transport of the semi-coke 01.

[0028] refer to Figure 3 , 6As shown, in this embodiment, the driving component 14 includes a plurality of driving chain links 141 and a plurality of driving scrapers 142 connected between two adjacent driving chain links 141. The driving chain links 141 are connected to the first sprocket 12 and the second sprocket 13. The mounting frame 11 is provided with transport grooves 1101 located on both sides of the support plate 16. The transport grooves 1101 are connected to the support plate 16. Both ends of the driving scrapers 142 are in contact with the inner side of the transport grooves 1101. The driving chain links 141 and the driving scrapers 142 enable continuous transport of multiple batches of semi-coke 01 to be transported. The transport grooves 1101 limit the horizontal ends of the semi-coke 01 to be transported, preventing leakage.

[0029] refer to Figure 4 , 5 As shown, in this embodiment, the mounting frame 11 is provided with an evaporation space 4, which connects the area between the top of the mounting frame 11 and the support plate 16, so as to increase the contact area between the semi-coke 01 to be transported and the air, and improve the evaporation rate of the semi-coke.

[0030] In this embodiment, the drive scraper 142 is provided with a material dropping surface 1421, which is inclined. In actual application, when the semi-coke to be transported 01 is removed from the support plate 16, the semi-coke to be transported 01 falls along the material dropping surface 1421 to the synchronous belt assembly 2 under the action of gravity, which facilitates the guidance of the semi-coke to fall and prevents material jamming.

[0031] refer to Figure 1 , 5 As shown, in this embodiment, the mounting frame 11 is equipped with a discharge hopper 5, which is connected to the top of the support plate 16 to facilitate the discharge of the semi-coke 01 to be transported from the support plate 16.

[0032] refer to Figure 3 , 6 As shown, in this embodiment, the drive scraper 142 is provided with a collection trough 1422. When the semi-coke to be transported 01 moves upward along the support plate 16, the semi-coke to be transported 01 is accumulated in the accommodating space formed by the collection trough 1422, the falling surface 1421, the upper surface of the support plate 16, and the transport trough 1101. The collection trough 1422 collects part of the semi-coke to be transported. During the upward transport of the semi-coke to be transported 01, the bottom end of the semi-coke to be transported 01 is stably supported and accumulated at the collection trough 1422, preventing the semi-coke to be transported 01 from scattering on the drive scraper 142. When the semi-coke to be transported 01 loses the support of the support plate 16, it can fall quickly, indirectly improving the material transfer efficiency.

[0033] refer to Figure 1 , 5As shown, in this embodiment, the discharge hopper 5 is provided with an inclined discharge channel 51. The bottom end of the discharge channel 51 faces the synchronous belt assembly 2. The discharge channel 51 is used to transport the semi-coke 01 to be transported. After being sent out by the support plate 16 through the inclined discharge channel 51, the semi-coke 01 to be transported can be piled up in batches on the discharge hopper 5. The semi-coke 01 to be transported slowly falls onto the synchronous belt assembly 2 on the discharge channel 51 by gravity, providing an interval time between the semi-coke 01 to be transported on the synchronous belt assembly 2 and the support plate 16. The specific interval time is determined by the inclination angle of the discharge channel 51. The larger the inclination angle of the discharge channel 51 to the horizontal plane, the faster the semi-coke 01 to be transported falls, thereby meeting the transportation needs of different semi-coke 01 to be transported and improving the versatility of semi-coke transportation.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
