Description

Technical Field

[0001] This utility model relates to the field of coke oven production technology, and in particular to a coke oven heating temperature control device. Background Technology

[0002] A coke oven is a piece of equipment specifically used for coal to produce coke. It is the main thermal equipment for coking. A modern coke oven typically consists of a carbonization chamber, a combustion chamber, a regenerator, an inclined section, a roof, a foundation, and a flue.

[0003] In the coke oven production process, precise control of heating temperature plays a decisive role in the quality of coke. In traditional coke oven heating systems, the layout of temperature sensors is not reasonable enough, and the temperature in some corner areas is difficult to monitor effectively. This makes it impossible to fully and accurately reflect the actual temperature in different areas of the coke oven, resulting in large errors in temperature monitoring. This affects the accuracy of overall temperature control and, consequently, the normal operation of coke oven production, making the system impractical. Therefore, a redesign is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coke oven heating temperature control device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coke oven heating temperature control device includes an oven body. A circular guide rail is fixedly installed on the inner wall of the oven body. Multiple sliders are slidably installed inside the circular guide rail. Each slider has a connecting plate fixedly connected to its upper end face via a connecting mechanism. A bevel gear ring is fixedly installed on the upper end face of the connecting plate. A rotating shaft is rotatably installed through the outer wall of the oven body. A bevel gear that meshes perpendicularly with the bevel gear ring is fixedly installed on the outer wall of the rotating shaft. A motor connected to the rotating shaft is fixedly installed on the outer wall of the oven body via a support mechanism. A high-temperature resistant temperature sensor is fixedly installed on the inner wall of the connecting plate via an installation mechanism.

[0007] Preferably, the connecting mechanism includes a connecting rod fixedly installed on the upper end face of the slider, and the end of the connecting rod is fixedly connected to the bottom wall of the connecting plate.

[0008] Preferably, the support mechanism includes a support plate fixedly installed on the outer wall of the furnace body, and the motor is fixedly installed on the outer wall of the support plate.

[0009] Preferably, the mounting mechanism includes a mounting plate fixedly installed on the inner wall of the connecting plate, and the high-temperature resistant temperature sensor is fixedly installed on the bottom of the mounting plate.

[0010] Preferably, a protective cover that mates with a bevel gear ring and a bevel gear is fixedly installed on the inner wall of the furnace, and the outer wall of the protective cover has a rotating opening that mates with the bevel gear ring.

[0011] Preferably, two connecting rods are fixedly installed on the upper surface of the protective cover, and a cleaning brush that mates with a beveled ring is fixedly installed at the end of each of the two connecting rods. Both cleaning brushes are made of stainless steel.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as circular guide rails, sliders, bevel gear rings, and bevel gears, the rotation of the bevel gears meshing with the bevel gear rings can transmit force to the connecting plate. The connecting plate, under the force, drives the slider to slide inside the circular guide rail through the cooperation of the connecting rod. This allows the connecting plate, through the cooperation of the mounting plate, to drive the high-temperature sensor to rotate circumferentially along the inner wall of the furnace. This enables the high-temperature sensor to effectively monitor the temperature in some corner areas of the furnace, thereby improving the accuracy of the overall temperature control inside the furnace.

[0014] 2. By setting up components such as a protective cover, connecting rod, and cleaning brush, the protective cover can block debris inside the furnace body 1, thereby preventing debris from falling onto the outer wall of the bevel gear. With the connecting rod fixed, the two cleaning brushes can clean the debris on the surface of the bevel gear ring, thereby preventing debris from increasing wear between the bevel gear and the bevel gear ring, thus improving the service life of the bevel gear and the bevel gear ring.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A coke oven heating temperature control device includes a furnace body 1. Its structural design closely revolves around the requirements of efficient temperature monitoring and precise control. A circular guide rail 2 is fixedly installed on the inner wall of the furnace body 1. The circular guide rail 2 is made of high-temperature resistant and high-strength alloy material, such as special alloy steel containing a high proportion of chromium and nickel elements. It can withstand the long-term high-temperature environment and complex thermal stress changes inside the coke oven, ensuring the stability of its own structure. Multiple sliders 3 are slidably installed inside the circular guide rail 2. The number of sliders 3 is reasonably set according to the actual size of the coke oven and the temperature monitoring accuracy requirements, generally between six and twelve, to ensure comprehensive coverage of the temperature in the circumferential direction of the inner wall of the furnace body 1.

[0023] Each slider 3 has a connecting plate 5 fixedly connected to its upper end face via a connecting mechanism. The connecting mechanism includes a connecting rod 4 fixedly installed on the upper end face of the slider 3. The connecting rod 4 is made of the same high-temperature resistant alloy material as the guide rail. Its end is fixedly connected to the bottom wall of the connecting plate 5 by welding to ensure the firmness of the connection and prevent loosening under high temperature and vibration. A beveled tooth ring 6 is fixedly installed on the upper end face of the connecting plate 5. The beveled tooth ring 6 is made of a special high-temperature resistant and wear-resistant alloy. The tooth surface has undergone special hardening treatment to improve its wear resistance under high temperature and high load operation.

[0024] A rotating shaft 7 is rotatably installed through the outer wall of the furnace body 1. The rotating shaft 7 is rotatably connected to the outer wall of the furnace body 1 through a high-precision high-temperature resistant bearing. The bearing is made of ceramic material, which has good high-temperature resistance and low friction characteristics, and can operate stably for a long time in high-temperature environments. A bevel gear 8 that meshes perpendicularly with the bevel gear ring 6 is fixedly installed on the outer wall of the rotating shaft 7. The meshing accuracy of the two has been strictly calibrated to ensure the smoothness and accuracy of power transmission. A motor 10 connected to the rotating shaft 7 is fixedly installed on the outer wall of the furnace body 1 through a support mechanism. The support mechanism includes a support plate 9 fixedly installed on the outer wall of the furnace body 1. The support plate 9 is made of thick steel plate and reinforced with ribs to enhance its support stability. The motor 10 is fixedly installed on the outer wall of the support plate 9. The motor 10 is a specially made high-temperature resistant motor that can stably output power in high-temperature environments. It is connected to the rotating shaft 7 through a coupling to ensure the high efficiency of power transmission.

[0025] A high-temperature resistant temperature sensor 12 is fixedly installed on the inner wall of the connecting plate 5 by an installation mechanism. The installation mechanism includes an installation plate 11 fixedly installed on the inner wall of the connecting plate 5. The installation plate 11 is made of ceramic material with high temperature resistance and good insulation performance to avoid electrical interference in high temperature environment. The high-temperature resistant temperature sensor 12 is fixedly installed on the bottom of the installation plate 11. The sensor probe is made of special high temperature and corrosion resistant material, such as platinum-rhodium alloy, which can accurately measure the high temperature environment in the coke oven with a measurement accuracy of ±1℃.

[0026] A protective cover 13 is fixedly installed on the inner wall of the furnace body 1 to cooperate with the bevel gear ring 6 and the bevel gear 8. The protective cover 13 is made of high temperature and high strength steel plate and has been treated with surface heat insulation to reduce heat transfer. The outer wall of the protective cover 13 has a rotating opening that cooperates with the bevel gear ring 6. The size of the rotating opening is precisely matched with the bevel gear ring 6, which can not only ensure the smooth rotation of the bevel gear ring 6, but also effectively block the corrosion of the bevel gear ring 6 and the bevel gear 8 by the high temperature gas and dust in the furnace.

[0027] Two connecting rods 14 are fixedly installed on the upper surface of the protective cover 13. The connecting rods 14 are made of steel plates of the same material as the protective cover. Each of the connecting rods 14 has a cleaning brush 15 fixedly installed at its end, which cooperates with the bevel gear ring 6. Both cleaning brushes 15 are made of 310S stainless steel. 310S stainless steel has excellent high temperature resistance and can work normally at temperatures up to 1200℃. It can adapt to the high temperature environment inside the coke oven. The bristles of the cleaning brush 15 are closely arranged and have a certain degree of elasticity. During the rotation of the bevel gear ring 6, it can effectively remove the dust and impurities on its surface, ensuring good meshing between the bevel gear ring 6 and the bevel gear 8, thereby ensuring the stable operation of the entire transmission system.

[0028] In use, the high-temperature resistant temperature sensor 12 can be fixedly installed at the bottom of the mounting plate 11 and connected to the data processing module and control module through existing wireless transmission technology. When detecting and controlling the temperature inside the furnace body 1, the motor 10 can drive the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, it can drive the bevel gear 8 to rotate and mesh with the bevel gear ring 6. Since the bevel gear 8 and the bevel gear ring 6 mesh perpendicularly, this meshing method can smoothly and efficiently transmit the rotational power of the motor 10 to the bevel gear ring 6. At this time, the bevel gear ring 6 can transmit the force it receives to the connecting plate 5. The connecting plate 5 is forced to slide the slider 3 inside the circular guide rail 2 through the cooperation of the connecting rod 4. Thus, the connecting plate 5 can drive the high-temperature resistant temperature sensor 12 to rotate circumferentially along the inner wall of the furnace body 1 through the cooperation of the mounting plate 11. This allows the high-temperature resistant temperature sensor 12 to effectively monitor the temperature of some corner areas of the furnace body 1, so as to improve the accuracy of the overall temperature control inside the furnace body 1.

[0029] Furthermore, during the meshing process of the bevel gear 8 and the bevel ring 6, the protective cover 13 can shield the debris inside the furnace body 1, thereby preventing the debris from falling onto the outer wall of the bevel gear 8 and thus preventing the meshing between the bevel gear 8 and the bevel ring 6. This ensures that the high-temperature sensor 12 can rotate normally. During the rotation of the bevel ring 6, due to the complex internal environment of the furnace body 1, dust and impurities in the coke oven can easily adhere to the surface of the bevel ring 6. If not cleaned in time, these debris will become embedded in the gear meshing area. At this time, the two cleaning brushes 15 can clean the debris on the surface of the bevel ring 6, thereby preventing the debris from increasing the wear between the bevel gear 8 and the bevel ring 6, and thus improving the service life of the bevel gear 8 and the bevel ring 6.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
