Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement processing decomposition furnace technology, specifically to an oxidation zone volume adjustment device. Background Technology
[0002] The cement decomposition furnace is one of the core pieces of equipment in a new dry-process cement production line, playing a crucial role in the calcination of cement clinker. It is a high-temperature gas-solid multiphase reactor where fuel and raw materials are fully mixed and undergo decomposition reactions. The fuel burns within the furnace, releasing a large amount of heat and maintaining the furnace temperature at approximately 850℃-950℃, providing suitable conditions for the decomposition of substances such as calcium carbonate. Calcium carbonate in the raw materials rapidly decomposes into calcium oxide and carbon dioxide under this high-temperature environment, significantly improving the calcination efficiency of the subsequent rotary kiln. The decomposition furnace offers numerous advantages. Its unique structural design ensures full contact between fuel and raw materials, resulting in high combustion efficiency and low heat loss. Simultaneously, it effectively reduces emissions of pollutants such as nitrogen oxides, meeting environmental protection requirements. Furthermore, the decomposition furnace enables continuous and stable production, improving the automation level and production efficiency of cement production, and ensuring stable cement clinker quality. It is an important piece of equipment for achieving efficient, energy-saving, and environmentally friendly production in the modern cement industry.
[0003] In existing cement processing decomposition furnaces, the structure and layout of the oxidation zone are fixed during the design phase. The furnace body is usually made of steel shell, and the interior is built with refractory materials to form a fixed combustion and reaction space. As part of the furnace body, the shape and size of the oxidation zone are basically determined after the furnace body is built, and it cannot be flexibly adjusted according to actual production needs. This fixed structure makes the volume of the oxidation zone a fixed value, which is difficult to meet the volume adjustment needs under different production conditions. Therefore, we need an oxidation zone volume adjustment device. Utility Model Content

[0022] This utility model embodiment provides an oxidation zone volume adjustment device, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the furnace includes a furnace body 1, an adjusting assembly 2 fixedly connected to one side of the furnace body 1, a sensor 3 installed on the top of the furnace body 1, a flue pipe 4 fixedly connected to the top of the furnace body 1, and a conveying assembly 5 installed inside the furnace body 1. The adjusting assembly 2 includes a motor 201, a lead screw 202 fixedly connected to the output end of the motor 201, a guide sleeve 203 threadedly connected to the outer wall of the lead screw 202, a partition 204 fixedly connected to one side of the guide sleeve 203, a high-temperature resistant sealing sleeve 205 installed on the outer wall of the partition 204, a sliding sleeve 206 fixedly connected to one side of the partition 204, a sliding rod 207 slidably connected inside the sliding sleeve 206, and an installation rod 208 fixedly connected inside the furnace body 1. A spring 209 is fitted onto the outer wall of the installation rod 208. An installation sleeve 210 is slidably connected to the outer wall of the mounting rod 208. A movable rod 211 is movably connected to one side of the mounting sleeve 210. The motor 201 can drive the lead screw 202 to rotate within the guide sleeve 203, allowing the partition 204 to slide along the outer wall of the slide rod 207 via the sliding sleeves 206 on both sides. This allows for position adjustment of the partition 204. The partition 204 also slides along the outer wall of the mounting rod 208 via the movable rod 211, which compresses the spring 209. Furthermore, the partition 204 can slide stably within the furnace body 1 via the external high-temperature resistant sealing sleeve 205, thus adjusting the volume of the oxidation zone within the furnace body 1 to meet daily usage needs.
[0023] Further, such as Figure 3 , Figure 4 and Figure 5 As shown, the motor 201 forms a threaded structure with the lead screw 202 and the guide sleeve 203. The outer diameter of the lead screw 202 matches the inner diameter of the guide sleeve 203, and the outer wall of the lead screw 202 fits against the inner wall of the guide sleeve 203, which enhances the connection between the motor 201 and the lead screw 202, allowing the motor 201 to drive the lead screw 202 to rotate within the guide sleeve 203.
[0024] Further, such as Figure 3 , Figure 4 and Figure 5As shown, the guide sleeve 203 forms a fixed structure with the high-temperature resistant sealing sleeve 205 through the partition 204, and the high-temperature resistant sealing sleeve 205 is set on the outer wall of the partition 204. The high-temperature resistant sealing sleeve 205 is a ceramic fiber sealing gasket. Through the partition 204, the high-temperature resistant sealing sleeve 205 can be set between the partition 204 and the furnace body 1 to ensure the sealing of the oxidation zone during the adjustment process.
[0025] Further, such as Figure 3 , Figure 4 and Figure 5 As shown, the guide sleeve 203 forms a sliding structure with the slide rod 207 via the sliding sleeve 206. The inner diameter of the sliding sleeve 206 matches the outer diameter of the slide rod 207, and the outer wall of the slide rod 207 is fitted to the inner wall of the sliding sleeve 206. The guide sleeve 203 can drive the partition 204 to move, allowing the partition 204 to slide stably along the outer wall of the slide rod 207 by relying on the sliding sleeve 206.
[0026] Further, such as Figure 3 , Figure 4 and Figure 5 As shown, the mounting sleeve 210 forms a movable structure with the partition 204 via the movable rod 211, and the movable rod 211 is disposed between the mounting sleeve 210 and the movable rod 211. Through the mounting sleeve 210, the partition 204 can compress the spring 209 by driving the mounting sleeve 210 on the movable rod 211 when it moves.
[0027] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the conveying assembly 5 includes an oxygen conveyor 501. One end of the oxygen conveyor 501 is connected to a mixing conveying pipe 504 via a connecting pipe 502. A first flow regulating valve 503 is provided on the outer wall of the connecting pipe 502, and a second regulating valve 505 is provided on the outer wall of the mixing conveying pipe 504.

At the same time, relying on the oxygen conveyor 501, oxygen can be conveyed through the connecting pipe 502, and the amount of oxygen conveyed can be controlled by the first flow regulating valve 503. Meanwhile, pulverized coal is conveyed by the second regulating valve 505, and pulverized coal and oxygen can be conveyed simultaneously by the mixing conveying pipe 504.
[0028] Further, such as Figure 1As shown, the furnace body 1 is equipped with multiple sensors 3, including temperature sensors, oxygen sensors, and CO sensors. These sensors are distributed in different locations within the oxidation zone to monitor the working conditions of the oxidation zone in real time and transmit the data to the control system for precise adjustment of the oxidation zone volume.
[0029] Working Principle: During operation, the furnace body 1 can be used to mix and burn carbon powder and oxygen. Simultaneously, an oxygen conveyor 501, connected to a connecting pipe 502, supplies oxygen. A first flow regulating valve 503 controls the oxygen supply. A second regulating valve 505 supplies pulverized coal, and a mixing and conveying pipe 504 simultaneously supplies both pulverized coal and oxygen. Temperature sensors, oxygen sensors, and CO sensors, distributed at different locations within the oxidation zone, monitor the oxidation zone's operating conditions in real time. The motor 201 drives the lead screw 202 to rotate within the guide sleeve 203, allowing the partition 204 to slide along the outer wall of the slide rod 207 via the sliding sleeves 206 on both sides, thereby adjusting the position of the partition 204. The partition 204 also slides along the outer wall of the mounting rod 208 via the movable rod 211 pulling the mounting sleeve 210, compressing the spring 209, and allowing the partition 204 to slide stably within the furnace body 1 via the external high-temperature resistant sealing sleeve 205. This adjusts the volume of the oxidation zone within the furnace body 1 to meet daily usage needs.
