Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon replacement equipment in furnace tubes, in particular to an activated carbon replacement structure in a furnace tube of a high-temperature pyrolysis furnace. Background Art

[0002] In the traditional high-temperature pyrolysis furnace tube structure, the replacement of activated carbon has always been a complicated and time-consuming process. Due to the compactness and complexity of the internal structure of the furnace tube, workers often need to spend a lot of time and energy when replacing the activated carbon, which not only seriously affects production efficiency, but also increases the difficulty of operation and safety risks. Specifically, the traditional replacement method usually requires the disassembly of the entire furnace tube structure, which is not only cumbersome to operate, but also easy to cause unnecessary damage to the furnace tube structure, shortening the service life of the furnace. In addition, the disassembly process may also cause safety hazards, such as burns in high temperature environments, poisoning caused by gas leaks, etc., further increasing the complexity and danger of the replacement process.

[0003] Moreover, during the operation of a high-temperature pyrolysis furnace, the stability of the furnace tube structure and the gas flowability are crucial to the overall performance of the furnace. However, traditional furnace tube structures often have many shortcomings, such as gas leakage, furnace tube detachment and other risks. These problems not only affect the normal operation of the furnace, but may also cause serious pollution to the production environment. At the same time, due to the unreasonable design of the activated carbon placement box, the gas may be obstructed when passing through the activated carbon layer, resulting in poor purification effect and failure to meet the strict requirements of the production process. In addition, the unstable connection between the filter cover and the activated carbon placement box may also cause gas leakage and activated carbon escape, further affecting the stability of the furnace tube structure and the effectiveness of gas circulation. These problems not only reduce the operating efficiency of the high-temperature pyrolysis furnace, but also increase maintenance costs and environmental pollution risks. To this end, we provide an activated carbon replacement structure in the furnace tube of a high-temperature pyrolysis furnace. Utility Model Content

[0021] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings. Example

[0022] like Figures 1-4 As shown, an embodiment of the present invention proposes a structure for replacing activated carbon in a high-temperature pyrolysis furnace tube, and its implementation is as follows:

[0023] Furnace tube 1 and furnace tube 2: Both are components of the high-temperature pyrolysis furnace. Furnace tube 2 2 is located downstream of furnace tube 1 and is used to further process the gas passing through furnace tube 1.

[0024] Cross plate 3: installed between furnace tube 1 and furnace tube 2 2, with a connecting rod 4 fixedly connected to the center thereof for supporting and positioning the activated carbon placement box 5.

[0025] Activated carbon placement box 5: installed at the end of the connecting rod 4 and located at the inner wall of the second furnace tube 2, used for storing activated carbon to adsorb and purify impurities in the gas.

[0026] Filter cover 6: covers the open end of the activated carbon placement box 5 to prevent the activated carbon from escaping while allowing gas to pass through.

[0027] Fixed ring piece 7: It is arranged at the inner wall of the activated carbon placement box 5 and is used to place the filter cover plate 6 to ensure that the cover plate is stable and does not fall off.

[0028] Through hole 8: is opened on the bottom wall of the activated carbon placement box 5, allowing gas to flow so that the gas can fully contact with the activated carbon.

[0029] Notch 17: opened on the end surface of furnace tube 2, used for placing cross plate 3 to ensure structural stability.

[0030] The disassembly and assembly structure includes a limiting plug hole 9, a rectangular groove 10, an overlapping slider 15 and a limiting plug rod 16, which are used to realize the rapid disassembly and assembly between the filter cover 6 and the activated carbon placement box 5.

[0031] Among them, through the above structure, the stable installation and rapid replacement of the activated carbon placement box 5 in the furnace tube 2 2 are achieved, while ensuring the effective circulation of gas and the full utilization of the activated carbon.

[0032] Furthermore, the reset component is implemented as follows:

[0033] The strip groove 11 is provided on the inner side wall of the rectangular groove 10 to provide installation space for the movable sleeve 14 and the spring 13 .

[0034] The transverse fixing rod 12 is fixedly connected between the two end walls of the strip groove 11 and serves as a sliding track for the movable sleeve block 14 .

[0035] Spring 13: sleeved on the transverse fixing rod 12, one end of which is connected to the end wall of the strip groove 11, and the other end of which is connected to the movable sleeve block 14, providing a reset force for the overlapping slider 15 and the limiting rod 16.

[0036] The movable sleeve block 14 is slidably sleeved on the periphery of the transverse fixing rod 12 and fixedly connected to the overlapping slider 15 to transmit the reset force of the spring 13.

[0037] Among them, when the filter cover 6 needs to be removed, the elastic force of the spring 13 can be manually overcome to pull the limit rod 16 out of the limit hole 9; when the filter cover 6 needs to be reinstalled, just align the limit rod 16 with the limit hole 9 and gently push it in. The elastic force of the spring 13 will automatically insert the limit rod 16 into the limit hole 9 to achieve quick fixation.

[0038] Furthermore, the connection method of furnace tube 1 and furnace tube 2 is as follows:

[0039] Flange 1 18 and flange 2 19 are fixedly mounted on the periphery of the ends of furnace tube 1 and furnace tube 2, respectively, and are used to connect the two furnace tubes.

[0040] Tightening screw 20: Threaded connection between flange 18 and flange 2 19, used to tighten the two flanges to ensure a stable connection between the furnace tubes.

[0041] Nut 21: Threadedly sleeved on the periphery of the tightening screw 20, used to further fix the tightening screw to prevent it from loosening.

[0042] Among them, through the above-mentioned connection method, a stable connection between furnace tube 1 and furnace tube 2 2 is achieved, ensuring the normal operation of the high-temperature pyrolysis furnace.

[0043] Furthermore, the connection between the movable sleeve 14 and the overlapping slider 15 is as follows:

[0044] The opposite surfaces of the two movable sleeve blocks 14 are fixedly connected to the two side surfaces of the overlapping slider 15 to form an integral structure.

[0045] The movable sleeve 14 is slidably connected to the inner wall of the strip groove 11 and moves along with the movement of the overlapping slider 15 .

[0046] Among them, this connection method ensures the stability and accuracy of the overlapping slider 15 and the limiting rod 16 during the movement process, and improves the reliability and service life of the disassembly and assembly structure.

[0047] Furthermore, the cooperation between the limiting rod 16 and the limiting hole 9 is as follows:

[0048] One end of the limiting rod 16 passes through the end wall of the rectangular groove 10 and is inserted into the inner wall of the limiting hole 9 .

[0049] The inner diameter of the limiting socket 9 is adapted to the designed outer diameter of the limiting rod 16 , ensuring that the limiting rod 16 can be tightly inserted into the limiting socket 9 , thereby achieving a stable connection between the filter cover 6 and the activated carbon placement box 5 .

[0050] Among them, through this matching mode, the filter cover plate 6 is ensured to be firmly installed on the activated carbon placement box 5, and the problems of gas leakage and activated carbon escape are prevented.

[0051] Furthermore, the installation and function of the spring 13 are as follows:

[0052] One end of the spring 13 is fixedly connected to the end wall of the strip groove 11 , and the other end is fixedly connected to one end surface of the moving sleeve block 14 .

[0053] The spring 13 provides a reset force for the overlapping slider 15 and the limit rod 16. When the filter cover 6 needs to be removed, the limit rod 16 can be pulled out manually by overcoming the elastic force of the spring 13; when the filter cover 6 is reinstalled, the elastic force of the spring 13 will automatically push the limit rod 16 into the limit hole 9.

[0054] The addition of the spring 13 makes the assembly and disassembly structure more flexible and convenient, thereby improving the efficiency of replacing the activated carbon. At the same time, the elastic force of the spring 13 also ensures a tight connection between the filter cover 6 and the activated carbon placement box 5, thereby preventing gas leakage and activated carbon from escaping.
