Description

Technical Field

[0001] This utility model relates to the field of cement production, and more specifically, to a decomposition furnace that prevents material accumulation and blockage. Background Technology

[0002] With the continuous advancement of modern cement industry technology and increasingly stringent environmental protection requirements, improving the operating efficiency of cement production lines, reducing energy consumption, and minimizing environmental pollution have become the focus of industry attention. In the cement production process, the decomposition furnace, as the core equipment of the preheating decomposition system, directly affects the overall production line's capacity, energy consumption, and product quality through its operational stability.

[0003] A search revealed that the existing Chinese utility model patent (application number: CN219869163U) discloses a "cement kiln decomposition furnace". Although this solution can avoid gas backflow, the aforementioned feed inlet still has the following problems: In the existing technology, if a large amount of material rushes into the mixing chamber, it will cause raw material to accumulate. Some raw material will not be fully dispersed before entering the interior, resulting in uneven contact with the flue gas. This will ultimately affect the sufficiency of the decomposition reaction, reduce the quality of clinker, and directly affect the efficiency of the decomposition reaction. It may even lead to an increase in side reactions and the generation of unqualified products due to excessively high or low local temperatures.

[0004] Therefore, we have made improvements to this by proposing a decomposition furnace that prevents material accumulation and blockage. Utility Model Content

[0005] The purpose of this invention is to solve the current problem of material blockage.

[0006] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a decomposition furnace designed to prevent material accumulation and blockage. The furnace includes a furnace body, a feed pipe fixedly connected to the top of the furnace body, a fixed plate fixedly connected to the top of the feed pipe, a belt groove inside the fixed plate, a first pulley and a second pulley disposed inside the belt groove, and a belt drivingly connecting the surfaces of the first and second pulleys. The first and second pulleys are synchronously driven by the belt. A second motor is fixedly connected to the top of the fixed plate, and the output end of the second motor is fixedly connected to one side of the first pulley. A rotating rod extending into the feed pipe is fixedly connected to one side of the first pulley, and a cleaning plate is fixedly connected to the bottom of the rotating rod. A sieve plate is fixedly connected inside the feed pipe, and a constricted tube is disposed inside the furnace body, with a scraping assembly disposed inside the constricted tube.

[0007] As a preferred technical solution of this application, the mounting shaft of the second pulley passes through the surface of the fixing plate and is rotatably connected to the interior of the fixing plate. One end of the mounting shaft of the second pulley protruding from the fixing plate is fixedly connected to a base plate, and a T-shaped groove is formed inside the base plate.

[0008] As a preferred technical solution of this application, a T-shaped block is slidably connected inside the T-shaped groove, and a sliding rod is fixedly connected inside the T-shaped groove, with the surface of the sliding rod slidably connected to the inside of the T-shaped block.

[0009] As a preferred technical solution of this application, a spring is fixedly connected inside the T-shaped groove, the side of the spring near the T-shaped block is fixedly connected to the surface of the T-shaped block, the spring is sleeved on the surface of the slide rod, a U-shaped plate is fixedly connected to the bottom of the T-shaped block, and a roller is rotatably connected inside the U-shaped plate.

[0010] As a preferred technical solution of this application, the scraping component includes a fixing block, the surface of which is fixedly connected to the inner wall of the constricted tube, and a transmission groove is provided inside the fixing block, with a first bevel gear rotatably connected inside the transmission groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the scheme of this application:

[0016] 1. Through the cement production process, the combination of cleaning plates and screen plates allows the material to be stirred on the surface of the screen plate, preventing the accumulation of large pieces of material, which could reduce the working efficiency of the decomposition furnace or even cause malfunctions. At the same time, it avoids uneven heating of the material and flue gas, which would reduce the working efficiency of the decomposition furnace. In addition, the combination of rollers and feed pipes further improves the uniform distribution of the material and vibrates the material on the inner wall of the feed pipe to prevent the material from accumulating on the inner wall.

[0017] 2. Through the cement production system, the cooperation of scrapers and motors can restore the uniform distribution of airflow, avoid material collapse caused by excessive local resistance, prevent the secondary combustion of unburned coal powder, which would exacerbate the crusting problem, maintain the stability of the temperature inside the decomposition furnace, and improve heat exchange efficiency, thereby reducing fuel consumption and heat consumption.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A decomposition furnace for preventing material accumulation and blockage includes a furnace body 1. A feed pipe 2 is fixedly connected to the top of the furnace body 1. A fixing plate 13 is fixedly connected to the top of the feed pipe 2. A belt groove 14 is formed inside the fixing plate 13. A first pulley 15 and a second pulley 17 are arranged inside the belt groove 14. A belt 16 is driven through the surfaces of the first pulley 15 and the second pulley 17, allowing synchronous transmission. A second motor 12 is fixedly connected to the top of the fixing plate 13. The output end of the second motor 12 is fixedly connected to one side of the first pulley 15. An extension extending into the feed pipe 2 is fixedly connected to one side of the first pulley 15. A rotating rod 25 is fixedly connected to a cleaning plate 27 at its bottom. A screen plate 26 is fixedly connected inside the feed pipe 2. The surface of the screen plate 26 has screen holes that are evenly distributed around the center of the screen plate 26. As the distance between the centers increases, the screen holes gradually enlarge, allowing large pieces of material to slide onto the large screen holes at the edge of the screen plate 26 as the cleaning plate 27 stirs the material, thus preventing the screen holes from clogging. The rotation of the rotating rod 25 causes the cleaning plate 27 to rotate on the surface of the screen plate 26, making the material spread evenly on the surface of the screen plate 26. At the same time, the material can fall evenly through the screen holes on the surface of the screen plate 26, preventing the material from rushing in and causing uneven mixing with the flue gas.

[0031] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the mounting shaft of the second pulley 17 passes through the surface of the fixed plate 13 and is rotatably connected to the interior of the fixed plate 13. A base plate 18 is fixedly connected to one end of the mounting shaft of the second pulley 17 that protrudes from the fixed plate 13. A T-shaped groove 19 is formed inside the base plate 18. A T-shaped block 20 is slidably connected inside the T-shaped groove 19. A slide rod 22 is fixedly connected inside the T-shaped groove 19. The surface of the slide rod 22 is slidably connected to the interior of the T-shaped block 20. A spring 21 is fixedly connected inside the T-shaped groove 19. The side of the spring 21 closest to the T-shaped block 20 is fixedly connected to the surface of the T-shaped block 20. The spring 21 is sleeved on the surface of the slide rod 22. The bottom of the T-shaped block 20 is fixedly connected to... There is a U-shaped plate 23, and a roller 24 is rotatably connected inside the U-shaped plate 23. The rotation of the second pulley 17 drives the bottom plate 18 to rotate. The bottom plate 18 drives the bottom U-shaped plate 23 to rotate through the T-shaped block 20. At the same time, when it rotates to a certain angle, the roller 24 can hit the outer wall of the feed pipe 2, vibrating the material in the feed pipe 2, improving the feeding efficiency, and preventing the material from sticking to the inner wall of the feed pipe 2. At the same time, because the roller 24 slides along the surface of the feed pipe 2, the roller 24 is subjected to pressure, which drives the U-shaped plate 23 and the T-shaped block 20 to squeeze the spring 21, so that the roller 24 can slide out on the surface of the feed pipe 2.

[0032] Example 2

[0033] The decomposition furnace for preventing material accumulation and blockage provided in Example 1 is further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the decomposition furnace body 1 has a constriction tube 3 inside, and a scraping assembly inside the constriction tube 3. The scraping assembly includes a fixing block 8. The top of the fixing block 8 has a conical cross-section, allowing the material to fall downwards along the conical surface. The surface of the fixing block 8 is fixedly connected to the inner wall of the constriction tube 3. A transmission groove 9 is opened inside the fixing block 8. A first bevel gear 10 is rotatably connected inside the transmission groove 9. A first motor 4 is fixedly connected to the surface of the constriction tube 3. The output end of the first motor 4 is fixedly connected to one side of the first bevel gear 10. A second bevel gear 11 is rotatably connected inside the transmission groove 9. The surface of the second bevel gear 11 meshes with the surface of the first bevel gear 10. A rotating rod 5 extending into the constriction tube 3 is fixedly connected to the bottom of the second bevel gear 11. A connecting rod 6 is fixedly connected to the surface of the rotating rod 5. A scraper 7 is fixedly connected to the side of the connecting rod 6 away from the rotating rod 5. The scraper 7 can scrape off the crust on the inner wall of the constriction tube 3.

[0034] The process of using the decomposition furnace for preventing material accumulation and blockage provided by this utility model is as follows:

[0035] By starting the second motor 12, the rotating rod 25 is driven to rotate, which in turn drives the cleaning plate 27 to rotate relative to the surface of the screen plate 26. This causes the material to be spread evenly on the surface of the screen plate 26. Simultaneously, the material passes through the screen holes on the surface of the screen plate 26. Because the screen holes are evenly distributed around the center of the screen plate 26, and the size of the screen holes gradually increases with the distance between the centers, large pieces of material can slide onto the larger screen holes at the edge of the screen plate 26 as the center, avoiding screen hole blockage and preventing material from rushing in and causing uneven mixing with the flue gas. At the same time, the rotation of the first pulley 15 drives the surface belt... The transmission of 16 enables the first pulley 15 and the second pulley 17 to drive synchronously. The rotation of the second pulley 17 drives the bottom plate 18 to rotate. The bottom plate 18 drives the bottom U-shaped plate 23 to rotate through the T-shaped block 20. At the same time, when it rotates to a certain angle, the roller 24 can hit the outer wall of the feed pipe 2, vibrating the material inside. At the same time, because the roller 24 slides along the surface of the feed pipe 2, the roller 24 is subjected to pressure, which drives the U-shaped plate 23 and the T-shaped block 20 to squeeze the spring 21, so that the roller 24 can slide out of the surface of the feed pipe 2.

[0036] By starting the first motor 4, the first bevel gear 10 is driven to rotate, which in turn drives the second bevel gear 11 on one side to rotate. The first bevel gear 10 and the second bevel gear 11 are synchronously driven by the teeth on their surfaces. The second bevel gear 11 drives the bottom rotating rod 5 to rotate, and through the connecting rod 6 on the surface, it drives the scraper 7 on one side to scrape off the crust on the inner wall of the constricted tube 3.
