Abstract
Description
Technical Field
[0001] This utility model relates to the field of semi-coke production technology, specifically to a coke discharge device for semi-coke production. Background Technology
[0002] Semi-coke is made by burning refined coal lumps. As a new type of carbon material, it is gradually replacing metallurgical coke and is widely used in the production of products such as calcium carbide, ferroalloys, ferrosilicon, and silicon carbide due to its characteristics of high fixed carbon content, high resistivity, high chemical activity, low ash content, low aluminum content, low sulfur content, and low phosphorus content. It has become an irreplaceable carbon material. Semi-coke production requires the use of a coking device. During the coking process, various by-products are generated, including coal gas, tar, crude benzene, sulfur, activated carbon, coal tar residue, and semi-coke powder.
[0003] Currently used coking equipment sometimes results in some powder entering the exhaust pipe during gas cleaning. Powder deposits on the inner wall of the exhaust pipe can cause blockages and impede gas flow, affecting the normal operation and performance of the equipment. This requires staff to regularly disassemble and clean the exhaust pipe, which is cumbersome. Furthermore, some coking equipment filter plates lack vibration functionality, allowing powder to accumulate and form a thick layer. This not only reduces filtration efficiency but can also clog the filter plates, hindering normal gas passage. Due to powder accumulation and reduced filtration effectiveness, regular cleaning and replacement of the filter plates are necessary, increasing maintenance costs and potentially impacting production schedules.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0021] Please see Figure 1-4As shown, a coking device for semi-coke production includes a base plate 1. A heating furnace body 2 is bolted to one side of the top of the base plate 1. Under the action of the heating furnace body 2, the semi-coke is heated and coked. A cooling device 3 is bolted to one side of the top of the base plate 1. Under the action of the cooling device 3, the processed semi-coke is cooled. An exhaust pipe 4 is connected to one side of the surface of the heating furnace body 2. Harmful gases such as coal gas and powder generated inside the heating furnace body 2 can enter the interior of the exhaust pipe 4. An electrically controlled valve 5 is installed on one side of the surface of the exhaust pipe 4. The intake time of the exhaust pipe 4 can be controlled by the action of the mechanism. A cleaning mechanism 6 is installed inside the exhaust pipe 4. The cleaning mechanism 6 cleans the powder adhering to the inner wall of the exhaust pipe 4. A rotating ring 7 is rotatably connected to the inner cavity of the exhaust pipe 4. The rotating ring 7 provides auxiliary support for the parts inside the cleaning mechanism 6. Several through holes 8 are formed on the surface of the rotating ring 7 and arranged in a circular array around the center point of the rotating ring 7. The through holes 8 prevent the rotating ring 7 from obstructing powder transport. The other end of the exhaust pipe 4... A collection box 9 is connected to the cooling device 3. The bottom of the collection box 9 is bolted to the top of the cooling device 3. Gas and powder inside the exhaust pipe 4 can enter the collection box 9. A fan 10 is connected to one side of the surface of the collection box 9. Under the action of the fan 10, gas and powder inside the heating furnace body 2 are drawn into the collection box 9 through the exhaust pipe 4. A frame 11 is slidably connected to one side of the inner wall of the collection box 9. A filter screen 12 is provided on the inner wall of the frame 11. The filter screen 12 can filter the gas and prevent the powder from being easily discharged. The collection box 9 is equipped with a vibration mechanism 13. When the fan 10 is running, the vibration mechanism 13 can be activated. The vibration mechanism 13 works in conjunction with the frame 11. When the vibration mechanism 13 is running, the frame 11 can move back and forth. When the frame 11 moves, the filter screen 12 can move. Both sides of the inner wall of the collection box 9 are provided with sliding grooves 14. A sliding plate 15 is slidably connected to one side of the inner wall of the sliding groove 14. One side of the surface of the sliding plate 15 is bolted to one side of the surface of the frame 11. Under the action of the sliding plates 15 on both sides, the frame 11 can move more stably.
[0022] The cleaning mechanism 6 includes a fixed frame 61. The upper and lower ends of the fixed frame 61 are respectively bolted to both sides of the inner wall of the exhaust pipe 4. A fan 62 is rotatably connected to one side of the surface of the fixed frame 61. When the gas inside the heating furnace body 2 enters the exhaust pipe 4, the fan 62 can be rotated. A transmission plate 63 is bolted to one side of the surface of the fan 62. When the fan 62 rotates, the transmission plate 63 can be rotated. Scrapers 64 are bolted to all four sides of the surface of the transmission plate 63. One side of the surface of the scraper 64 is in contact with the inner wall of the exhaust pipe 4. One side of the surface of the scraper 64 is triangular. When the four scrapers 64 rotate, they can clean the inner wall of the exhaust pipe 4. The other end of the surface of the scraper 64 is bolted to one side of the surface of the rotating ring 7. When the four scrapers 64 rotate, the rotating ring 7 can be rotated.
[0023] The vibration mechanism 13 includes a bevel gear 131, one side of which is bolted to one side of the fan 10. When the fan 10 runs, the bevel gear 131 rotates. A transmission rod 132 is bolted to one side of the inner wall of the bevel gear 131. Both ends of the transmission rod 132 are rotatably connected to the two sides of the inner wall of the collection box 9. When the bevel gear 131 rotates, it drives the transmission rod 132 to rotate. Cams 133 are bolted to both ends of the transmission rod 132. When the transmission rod 131 rotates, it drives the transmission rod 132 to rotate. When rotated, the cams 133 on both sides can rotate. Tension springs 134 are fixedly connected to the surface of the frame 11. There are four tension springs 134, which are evenly distributed on the four sides of the surface of the frame 11. The other end of the surface of the tension spring 134 is fixedly connected to one side of the inner wall of the collection box 9. When the cams 133 on both sides rotate to the appropriate position, the frame 11 can move. When the frame 11 moves, the tension springs 134 on the four sides can be stretched. This process is repeated so that the frame 11 can always be in a moving state.
[0024] Working principle: When gas and some powder inside the heating furnace body 2 enter the exhaust pipe 4, the fan 62 rotates under the action of the gas. When the fan 62 rotates, it drives the transmission plate 63 to rotate. Then, the rotation of the transmission plate 63 drives the scrapers 64 on all four sides to rotate. When the scrapers 64 on all four sides rotate, they drive the rotating ring 7 to rotate. Then, the movement of the scrapers 64 on all four sides cleans the inside of the exhaust pipe 4, preventing impurities from accumulating on the inner wall of the exhaust pipe 4. When the blower 10 runs, it drives the bevel gear 131 to rotate. When the bevel gear 131 rotates, it drives the transmission rod 132 to rotate. Then, the rotation of the transmission rod 132 drives the cams 133 on both sides to rotate. Then, the cams 133 on both sides rotate to a suitable position, which moves the frame 11. When the frame 11 moves, it stretches the tension springs 134 on all four sides. Then, the cams 133 on both sides continue to rotate. Under the action of the tension springs 134 on all four sides, the frame 11 returns to its original position. This process is repeated, which keeps the frame 11 in a state of constant movement and vibration. The movement of the frame 11 causes the filter screen 12 to move, which prevents powder from adhering to the surface of the filter screen 12.
[0025] 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.
