Description

Technical Field

[0001] This utility model relates to an oxidation furnace that is easy to maintain, and belongs to the field of oxidation furnace technology. Background Technology

[0002] Oxidation furnaces are key pieces of equipment in industrial production used to achieve material oxidation reactions, and are widely used in industries such as chemical engineering, metallurgy, and new material synthesis. Their core working principle involves feeding the material to be oxidized into the furnace body through a conveying pipeline under specific temperature, pressure, and atmospheric conditions. A heating device ensures that the material comes into full contact with the oxidant (such as air or oxygen) to undergo an oxidation reaction, generating the target product, which is then output through appropriate pipelines. Simultaneously, auxiliary systems such as temperature control and pressure monitoring ensure stable reaction processes. However, traditional oxidation furnace designs lack dedicated access mechanisms for maintenance work, forcing maintenance personnel to rely on external ladders or lifting platforms, increasing their workload.

[0005] By adopting the above technical solution, when maintenance is required at the connection between the conveying pipeline and the oxidizer body, the sliding block is first moved within the sliding groove, causing the first and second ladders to move synchronously. Once the first ladder has moved to the appropriate position, the limiting structure limits the sliding block and the mounting plate, thus fixing the positions of the first and second ladders. Then, based on the height of the conveying pipeline, the height of the second ladder is adjusted using the moving structure. This device can precisely adapt to conveying pipelines at different positions and heights by flexibly adjusting the positions of the first and second ladders, meeting all-round maintenance needs, and effectively reducing the labor intensity of maintenance personnel without the need for external auxiliary structures.

Detailed Implementation

[0018] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0019] like Figure 1 and Figure 2As shown, an easy-to-maintain oxidation furnace includes a mounting plate 1. The mounting plate 1 is installed in a suitable position. The mounting plate 1 is circular. An oxidation furnace body 2 is fixedly mounted on the mounting plate 1. Several conveying pipes 3 are provided on the oxidation furnace body 2. A sliding groove 4 is opened on the mounting plate 1. The sliding groove 4 is opened along the circumference of the mounting plate 1. A sliding block 5 is slidably arranged inside the sliding groove 4. The sliding block 5 can move along the opening direction of the sliding groove 4. A limiting structure for limiting the sliding block 5 is provided in the sliding groove 4. One end of the sliding block 5 extends to the outside of the mounting plate 1 and is fixedly mounted with a first ladder 6. A second ladder 7 is provided on one side of the first ladder 6. The first ladder 6 and the second ladder 7 move synchronously with the sliding block 5. A moving structure for moving the second ladder 7 is provided on the first ladder 6.

[0020] like Figures 2 to 4 As shown, the limiting structure includes a positioning block 1011, a positioning groove 1012, a limiting block 1013, a limiting groove 1014, and a pushing part. The positioning block 1011 is fixedly mounted on the sliding block 5. One end of the positioning block 1011 extends to the outer side of the mounting plate 1. The positioning groove 1012 is vertically opened on the positioning block 1011. The limiting block 1013 is slidably mounted inside the positioning groove 1012. The limiting groove 1014 is opened on the inner wall of the sliding groove 4. Several limiting grooves 1014 are opened, and the several limiting grooves 1014 are arranged in a circumferential array along the opening direction of the sliding groove 4, which can meet the actual needs of all-round maintenance of the conveying pipeline 3. The limiting block 1013 can be inserted into the corresponding limiting groove 1014. The pushing part is mounted on the positioning block 1011 and is used to push the limiting block 1013 into the limiting groove 1014.

[0021] like Figure 4 As shown, the pushing part includes a positioning plate 1021, a connecting rod 1022, a lever 1023, and a spring 1024. The positioning plate 1021 is slidably disposed inside the positioning groove 1012 and slides along the opening direction of the positioning groove 1012. The limiting block 1013 is fixedly connected to the positioning plate 1021 and moves synchronously with the positioning plate 1021. One end of the limiting block 1013 can extend to the outside of the positioning block 1011 and be inserted into the limiting groove 1014. The connecting rod 1022 is fixedly disposed on the positioning plate 1021 away from the limiting groove 1024. On one side of block 1013, one end of connecting rod 1022 extends to the outside of positioning block 1011 and is fixedly connected to lever 1023. Spring 1024 is located between positioning plate 1021 and positioning groove 1012. Both ends of spring 1024 are fixedly connected to the inner walls of positioning plate 1021 and positioning groove 1012 respectively. When spring 1024 is not under force, it is in a stretched state. At this time, limiting block 1013 and limiting groove 1014 are separated. When spring 1024 is under force, it is in a compressed state. At this time, limiting block 1013 and limiting groove 1014 are in an inserted state.

[0022] like Figure 3 As shown, the movable structure includes a fixed block 1031, a guide groove 1032, a guide block 1033, and a locking part. The fixed block 1031 is fixedly disposed on both sides of the second ladder 7. The guide groove 1032 is vertically opened on the first ladder 6. Two guide grooves 1032 are provided, and the two guide grooves 1032 are respectively aligned with the fixed block 1031. The guide block 1033 is slidably disposed inside the guide groove 1032 and slides along the opening direction of the guide groove 1032. One side of the fixed block 1031 extends into the guide groove 1032 and is fixedly connected to the guide block 1033. The fixed block 1031 moves synchronously with the guide block 1033. The locking part is disposed on the first ladder 6 and is used to lock the first ladder 6 and the second ladder 7.

[0023] like Figure 2 and Figure 3 As shown, the locking part includes a first threaded hole 1041, a second threaded hole 1042, a locking rod 1043, and a rotating block 1044. The first threaded hole 1041 and the second threaded hole 1042 are formed on the inner wall of the guide groove 1032, and are located at opposite ends of the guide groove 1032. The locking rod 1043 is threaded onto the guide block 1033. One end of the locking rod 1043 can extend into the interior of the first threaded hole 1041 or the second threaded hole 1042 and be threadedly connected to the first threaded hole 1041 or the second threaded hole 1042. The other end of the locking rod 1043 extends to the outside of the first ladder 6 and is fixedly connected to the rotating block 1044. A toolbox 1051 is fixedly installed on the fixed block 1031. The toolbox 1051 provides a stable temporary storage space, avoiding the risk of tools accidentally slipping and being damaged, thus improving the safety of the device.

[0024] like Figure 2 As shown, the mounting plate 1 has a collection channel 1061 that communicates with the sliding groove 4. Support plates 1062 are fixedly installed on both sides of the sliding block 5. A scraper 1063 is fixedly installed on one side of the support plate 1062. The scraper 1063 slides against the inner wall of the sliding groove 4.

[0025] When maintenance is required at the connection between the conveying pipe 3 and the oxidation furnace body 2, first pull the lever 1023 to move the connecting rod 1022, causing the connecting rod 1022 to slide the positioning plate 1021 in the positioning groove 1012. This causes the positioning plate 1021 to move the limiting block 1013 away from the corresponding limiting groove 1014. During the movement, the positioning plate 1021 compresses the spring 1024, completing the separation of the limiting groove 1014 and the limiting block 1013. At this time, by moving the sliding block 5 in the sliding groove 4, the sliding block 5 drives the first ladder 6 and the second ladder 7 to move synchronously. After the ladder 6 is moved to the appropriate position, the limiting block 1013 is aligned with the appropriate limiting groove 1014. By releasing the lever 1023, the spring 1024 returns to its original position and pushes the positioning plate 1021 to slide inward. This causes the positioning plate 1021 to move the limiting block 1013 from the positioning groove 1012 towards the limiting groove 1014, so that the limiting block 1013 is inserted into the corresponding limiting groove 1014. This completes the limiting of the sliding block 5 and the mounting plate 1, thereby fixing the positions of the first ladder 6 and the second ladder 7. Then, according to the height of the conveying pipe 3, when it is necessary to adjust the height of the second ladder 7, first rotate the rotating block 1. 044 drives the locking rod 1043 to rotate. Under the action of the threaded structure, the locking rod 1043 moves away from the first threaded hole 1041, realizing the separation of the locking rod 1043 from the first threaded hole 1041, thereby removing the limit on the guide block 1033. Then, the second ladder 7 is pushed to move the fixing block 1031, so that the fixing block 1031 drives the guide block 1033 to move in the guide groove 1032 towards the second threaded hole 1042. When the locking rod 1043 is aligned with the second threaded hole 1042, the rotating block 1044 is rotated again to drive the locking rod 1043 to rotate. 3. Under the action of the threaded structure, it moves towards the second threaded hole 1042, so that the locking rod 1043 is inserted into the interior of the second threaded hole 1042, thereby limiting the guide block 1033 and thus completing the position limit of the second ladder 7. The second ladder 7 is stably fixed by the cooperation of the locking rod 1043 and the second threaded hole 1042, preventing accidental movement during maintenance and ensuring operational safety. This device can accurately adapt to the conveying pipe 3 at different positions and heights by flexibly adjusting the positions of the first ladder 6 and the second ladder 7, meeting all maintenance needs, and without the need for external auxiliary structures, effectively reducing the labor intensity of maintenance personnel.

[0026] When the sliding block 5 slides in the sliding groove 4, the support plate 1062 synchronously pushes the scraper 1063 to move, so that the scraper 1063 pushes the impurities inside the sliding groove 4 toward the collection channel 1061, so that the impurities are discharged through the collection channel 1061 to the outside of the mounting plate 1, ensuring that the sliding process of the sliding block 5 in the sliding groove 4 remains smooth and stable, and reducing the possibility of the sliding block 5 getting stuck due to impurities.
