Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of smoke exhaust of calcium carbide furnaces, and particularly relates to a smoke exhaust device in front of a furnace for calcium carbide production. Background Art
[0002] The calcium carbide furnace is the main equipment for producing calcium carbide. In the furnace, the high temperature generated by the electric arc causes the charge to melt and react to produce calcium carbide. The flue gas generated by the furnace needs to be collected by the furnace dust collection hood and discharged through the flue by the dust removal fan.
[0003] During the calcium carbide production process, the flue gas generated in front of the furnace contains large amounts of dust and other impurities. These impurities easily adhere to the inner walls of the exhaust ducts as they are discharged. Over time, these accumulated impurities can cause blockage in the exhaust ducts, hindering the smooth discharge of the flue gas and potentially polluting the production environment. They can even corrode production equipment, shortening its service life.
[0004] Traditional cleaning methods typically require the machine to be shut down, requiring workers to manually remove impurities from the exhaust duct. This method is not only inefficient, time-consuming, and labor-intensive, but also disrupts production continuity due to the need to shut down the machine. Furthermore, manual cleaning carries safety risks, such as the risk of injury from improper operation.
[0005] In recent years, technological advancements have led to the introduction of automated cleaning equipment into the fume extraction systems used in calcium carbide production. However, these devices are often complex, costly to operate and maintain, and, in some cases, offer suboptimal cleaning results. Furthermore, these devices often require specialized operating skills and maintenance knowledge, which can be challenging for small and medium-sized enterprises.
[0006] To this end, we proposed a furnace front smoke exhaust device for calcium carbide production. The device realizes automatic cleaning of the inner wall of the smoke exhaust channel by arranging scraper rings and connecting moving components inside the smoke exhaust channel. At the same time, the device also has the advantages of simple structure, easy operation and good cleaning effect. Utility Model Content

[0026] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.
[0027] like Figure 1-5 As shown, the technical solution adopted by the present invention is as follows: a furnace exhaust device for calcium carbide production, comprising an exhaust channel 1, a scraper ring 2 is provided inside the exhaust channel 1, and a threaded connection hole 3 is opened on the scraper ring 2;
[0028] A through groove 4 is provided on the smoke exhaust channel 1, and an arc-shaped plate 5 is installed inside the through groove 4. A connecting movable component is provided on the smoke exhaust channel 1 at a position above the through groove 4, and a threaded connecting rod 12 is provided on the connecting movable component. The threaded connecting rod 12 is inserted into the threaded connecting hole 3 for fixation.
[0029] Its working principle is: first, people discharge the flue gas in front of the calcium carbide production furnace through the smoke exhaust channel 1. When discharging, impurities in the smoke will stick to the inner wall of the smoke exhaust channel 1. When cleaning the impurities, it is necessary to stop the machine and then remove the arc plate 5. At this time, the through groove 4 is opened, and the threaded connecting rod 12 is fixed by entering the threaded connecting hole 3. Then, the scraper ring 2 is driven to move on the inner wall of the smoke exhaust channel 1 through the connecting moving component, thereby removing the impurities on the inner wall of the smoke exhaust channel 1. This device can not only solve the problem that dust in the smoke will stick to the inner wall of the pipe, but also achieve the effect of saving time and effort.
[0030] Among them, the diameter of the scraper ring 2 is the same as the diameter of the smoke exhaust channel 1, which means that the outer side of the scraper ring 2 fits with the inner wall of the smoke exhaust channel 1. When the scraper ring 2 moves, it can remove impurities on the inner wall of the smoke exhaust channel 1, thereby solving the problem that dust in the flue gas will stick to the inner wall of the pipe.
[0031] At the same time, arc-shaped mounting plates 6 are provided on both sides of the arc-shaped plate 5 , and the arc-shaped mounting plates 6 are mounted on the smoke exhaust channel 1 by bolts. This arrangement enables the arc-shaped plate 5 to be easily installed and removed from the smoke exhaust channel 1 through the arc-shaped mounting plates 6 .
[0032] The arc plate 5 matches the through groove 4 , and the matching here means that when the arc plate 5 enters the through groove 4 , the smoke exhaust channel 1 can exhaust smoke normally without smoke leakage.
[0033] In order to further improve the sealing performance, a sealing layer is provided on the arc plate 5 , and the sealing layer can be used to seal the arc plate 5 when it is installed in the through groove 4 to prevent smoke leakage.
[0034] The purpose of setting the through groove 4 is: first, the situation inside the smoke exhaust channel 1 can be observed, which is convenient for people to detect whether it is to be cleaned; second, the position of the scraper ring 2 can be determined, and a driving force is generated when the smoke enters the smoke exhaust channel 1. At the same time, because the scraper ring 2 is only in contact with the inner wall of the smoke exhaust channel 1, the thrust generated in this way can easily change the position of the scraper ring 2. The provision of the through groove 4 can quickly determine the position of the scraper ring 2 and quickly restore the scraper ring 2 to its original position.
[0035] like Figure 3 and Figure 4 As shown, the connecting moving assembly includes two fixed blocks 7 fixed on the smoke exhaust channel 1, a threaded rod 8 is rotatably arranged between the two fixed blocks 7, a rotating disk 9 is installed at one end of the threaded rod 8, and a threaded sleeve 10 is sleeved on the threaded rod 8, a hollow cylinder 11 is provided at the bottom of the threaded sleeve 10, and the hollow cylinder 11 is threadedly connected to the threaded connecting rod 12.
[0036] When in use, the threaded connecting rod 12 is rotated inside the hollow cylinder 11, so that the threaded connecting rod 12 moves down and is fixed when it moves to the position of the threaded connecting hole 3. Then, the threaded rod 8 is driven to rotate by the rotating disk 9, and the threaded rod 8 drives the threaded sleeve 10 to move the scraper ring 2, thereby removing impurities on the inner wall of the smoke exhaust channel 1.
[0037] The inner cavity of the hollow cylinder 11 is provided with a thread groove, which matches the threaded connecting rod 12 , so that the threaded connecting rod 12 can move on the thread groove, thereby causing the threaded connecting rod 12 to be displaced.
[0038] At the same time, the fixed block 7 and the smoke exhaust groove 4 are detachably arranged. The advantage of this arrangement is that the connected movable components can be installed and disassembled. The connection method here is bolt connection or clamping, which belongs to the existing technology and will not be elaborated here.
[0039] The working principle of this utility model is: first, people discharge the flue gas in front of the calcium carbide production furnace through the smoke exhaust channel 1. When discharging, impurities in the smoke will stick to the inner wall of the smoke exhaust channel 1. When cleaning the impurities, it is necessary to stop the machine and then remove the arc plate 5. At this time, the through groove 4 is opened, and the threaded connecting rod 12 is fixed by entering the threaded connecting hole 3. Then, the scraper ring 2 is driven to move on the inner wall of the smoke exhaust channel 1 through the connecting moving component, thereby removing the impurities on the inner wall of the smoke exhaust channel 1. This device can not only solve the problem that the dust in the smoke will stick to the inner wall of the pipe, but also achieve the effect of saving time and effort.
[0040] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
