Description

Technical Field

[0001] This utility model relates to the field of coking furnace technology, specifically a high-efficiency coking furnace type. Background Technology

[0002] Coking ovens are key equipment in the coking and petrochemical industries. They are mainly used to pyrolyze, crack, and condensate raw materials such as coal or heavy oil at high temperatures to produce coke, coal gas, coal tar, and light oil products. Coking is an important part of the coal chemical industry. The main coal processing methods are high-temperature coking, medium-temperature coking, and low-temperature coking. The metallurgical industry generally uses high-temperature coking to obtain coke and recover chemical products. The coke can be used as fuel for blast furnace smelting, or for casting, non-ferrous metal smelting, and the production of water gas. It can also be used to produce calcium carbide to obtain raw materials for organic synthesis. The chemical products generated during the coking process can be recovered and processed to extract products such as coal tar, ammonia, naphthalene, hydrogen sulfide, and crude benzene, and to obtain clean coke oven gas, coal tar, and crude benzene. After refining and further processing, benzene, toluene, xylene, carbon disulfide, etc., can be produced. These products are widely used in the chemical, pharmaceutical, refractory materials, and defense industries.

[0003] Referring to Chinese Patent Publication No. CN210560249U, published on May 19, 2020, a high-efficiency and environmentally friendly coking furnace is disclosed. This utility model solves the shortcomings of existing coking furnaces, such as low coking efficiency, high time and energy consumption, and waste of resources. The furnace includes a furnace body, a crushing chamber, and a screen plate. The crushing chamber is located at the top of the furnace body, and a servo motor is installed at the top of the crushing chamber. Crushing paddles are fixedly mounted on both sides of the output end of the servo motor connected to a drive shaft. Mounting grooves are provided on both sides of the bottom of the crushing chamber. This utility model uses the crushing chamber to initially crush the raw materials. Only materials crushed to a small size can pass through the screen plate and fall into the coking furnace, increasing the actual contact area during coking and thus improving coking efficiency. The screen plate is easy to replace and clean, ensuring the service life of the equipment.

[0004] However, although this utility model can crush the raw materials located in the crushing chamber during use, the crushing process is carried out by the crushing head moving in a circular motion. The crushing rate of the raw materials located in the crushing chamber is relatively slow, which affects the crushing speed and thus the efficiency of the coking furnace. Furthermore, if the raw materials are added too quickly, it can also cause blockage of the raw materials located in the crushing chamber, which also affects the efficiency of the coking furnace. Therefore, there is still room for further improvement.

[0005] Therefore, we propose a high-efficiency coking furnace design to address the problems mentioned above. Utility Model Content

Detailed Implementation

[0033] 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.

[0034] Please see Figure 1-5 As shown, this utility model provides a technical solution: a high-efficiency coking furnace, including: a coking furnace body 1, a crushing box 2, a feeding port 3, a limiting strip 4, a sliding plate 5, an electric telescopic rod 6, a first motor 7, a first crushing roller 8, a first gear 9, a second gear 10, a second crushing roller 11, a filter plate 12, a support block 13, a second motor 14, a connecting shaft 15, an eccentric wheel 16, a collection box 17, and a material pump 18.

[0035] While existing utility models can crush raw materials located in the crushing chamber, the crushing process is carried out by the circular motion of the crushing head, resulting in a slow crushing rate. This affects the crushing speed and thus the efficiency of the coking furnace. Furthermore, if the raw materials are added too quickly, it can cause blockages in the crushing chamber, also affecting the efficiency of the coking furnace. Therefore, there is still room for further improvement.

[0036] like Figure 1 As shown, a crushing box 2 is provided on the upper side of the coking furnace body 1. The components inside the crushing box 2 can crush the raw materials and then enter the coking furnace body 1 for coking. In addition, a feeding port 3 is provided on the upper side of the crushing box 2. The feeding port 3 can prevent the possibility of blockage caused by excessive material feeding, thereby facilitating coking.

[0037] like Figure 1 and Figure 3 As shown, a limiting strip 4 is provided on the inner side of the feeding port 3, and the limiting strip 4 is symmetrical about the vertical central axis of the feeding port 3. Before use, raw materials are added into the feeding port 3. When feeding, the electric telescopic rod 6 on the upper side of the crushing box 2 is activated. The electric telescopic rod 6 will move the sliding plate 5 through the vertical plate. At this time, the raw materials inside the feeding port 3 will fall due to gravity and enter the crushing box 2 for crushing. The sliding plate 5 is slidably connected to the limiting strip 4. Therefore, the limiting strip 4 can ensure that the sliding plate 5 can move horizontally back and forth in the feeding port 3, which is convenient for feeding. In addition, after feeding is finished, the electric telescopic rod 6 is activated again. The electric telescopic rod 6 will make the sliding plate 5 return to its original state to prevent the excessive falling raw materials from causing blockage.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, a first motor 7 is provided on the rear side of the crushing box 2, and the output shaft of the first motor 7 is fixedly connected to the first crushing roller 8. The first crushing roller 8 is rotatably connected to the crushing box 2. When the first motor 7 is started, the first motor 7 will cause the first crushing roller 8 to rotate. The rotating first crushing roller 8 will drive the first gear 9 to rotate. In addition, the first gear 9 is meshed with the second gear 10, and the second gear 10 is fixedly connected to the second crushing roller 11. The second crushing roller 11 is rotatably connected to the crushing box 2. Therefore, the rotating first crushing roller 8 will cause the second crushing roller 11 to rotate through the first gear 9 and the second gear 10. The rotation direction of the second crushing roller 11 is opposite to the rotation direction of the first crushing roller 8, which is beneficial to crushing raw materials and can effectively avoid uneven crushing of raw materials.

[0039] like Figure 1 Figure 4 and Figure 5 As shown, the filter plate 12 is rotatably connected to the crushing box 2, and the filter plate 12 is inclined to facilitate screening of the crushed raw materials. When the crushed raw material particles are large, they will enter the collection box 17. When the material pump 18 is started, the raw materials in the collection box 17 can be transported back to the inside of the feeding port 3 for crushing, and then crushed and screened again. This can effectively avoid the coking efficiency from deteriorating due to large particles and facilitate coking.

[0040] like Figure 1 Figure 4 and Figure 5 As shown, the lower left side of the filter plate 12 is tightly fitted with the support block 13. The support block 13 supports the filter plate 12, preventing it from moving down too much and facilitating screening. When the second motor 14 is started, the connecting shaft 15 rotates the eccentric wheel 16. At this time, the eccentric wheel 16 periodically contacts the filter plate 12. When the eccentric wheel 16 contacts the filter plate 12, it causes the filter plate 12 to rotate. When the eccentric wheel 16 disconnects from the filter plate 12, it causes the filter plate 12 to move down. When the filter plate 12 contacts the support block 13, it vibrates, thereby screening the raw materials. The smaller particles of raw materials enter the coking furnace body 1 for coking, while the larger particles are crushed again, thereby enhancing the efficiency of the coking furnace body 1.
