Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas oxidation device technology, and more specifically, to a seamless leak-proof gas oxidation device. Background Technology
[0002] Gas oxidation devices are key equipment for treating methane in coal mines. They oxidize the methane emitted from coal mines, significantly reducing the content of combustible components in the methane, minimizing safety hazards caused by methane, and also enabling the energy utilization of methane to a certain extent, thus contributing to safe production and environmental protection and energy conservation in coal mines.
[0003] The gas oxidation unit mainly consists of an outer shell, an insulation layer, a heat storage chamber (containing heat storage ceramics), a partition plate, and an oxidation reaction zone. Its principle is that the gas is first preheated in the heat storage chamber, then reacts with oxygen in the oxidation zone to produce carbon dioxide and water. After the reaction, the high-temperature gas is stored in another heat storage chamber to achieve heat circulation. The partition structure reduces gas leakage and improves processing efficiency.
[0004] In existing technologies, some gas oxidation devices experience thermal expansion and contraction of the partition plates during operation. When the partition plates are lowered during contraction, gaps are created. These gaps cannot be sealed before the partition plates contract, affecting the airtightness between the heat storage chambers. This leads to a significant reduction in treatment efficiency and an increase in methane concentration in the exhaust gas, making it difficult to meet the environmental protection requirements of this type of equipment. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a seamless leak-proof gas oxidation device to solve the problem that the gap below cannot be sealed before the partition plate is cooled and shrunk in the prior art.

[0007] The outer shell is a steel plate, and an insulation layer is fixedly connected to the outside of the outer shell. Multiple insulation layers are fixedly connected to one end away from the outer shell. Each of the multiple insulation layers has a partition plate slidably connected to its inner wall. A support cylinder is fixedly connected to the end away from the partition plate. Multiple elastic elements are fixedly connected to the inner wall of the support cylinder.

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

This ensures that the lower partition plate remains tightly against the component below during both the retracted and initial states, preventing gaps. Pressing the lower partition plate changes the angle and posture of the pressure rod, moving the pressure block away from the lower partition plate, thus enabling quick disassembly, replacement, and maintenance of the lower partition plate. Adjusting the angle to change the downward pressure allows for timely adjustments based on different processing environments, ensuring that gaps do not form under the lower partition plate.

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0026] Example 1: Please refer to Figures 1 to 7 This utility model provides a technical solution: a seamless leak-proof gas oxidation device, including an outer steel plate 1, an insulation layer 2 fixedly connected to the outside of the outer steel plate 1, a plurality of 3 fixedly connected to the end of the insulation layer 2 away from the outer steel plate 1, a partition plate 5 slidably connected to the inner wall of each of the plurality of 3, a supporting cylinder 6 fixedly connected to the end of the 3 away from the partition plate 5, a plurality of elastic elements 8 fixedly connected to the inner wall of the supporting cylinder 6, and a pull rod 10 slidably connected to the inner wall of the supporting cylinder 6. The cooperation between the elastic elements 8 and the pull rod 10 is the main component to ensure that the partition plate 5 fits tightly against the lower component without gaps, and a connecting ring 12 is fixedly connected to the inner wall of the pull rod 10.
[0027] Due to the influence of the elastic potential energy of the elastic element 8, the lower partition 5 always fits tightly against the component below in both the contracted and initial states, without creating gaps. Furthermore, when disassembling the lower partition 5, pressing the pull rod 10 increases the space on the lower partition 5, thus enabling the replacement or maintenance of the lower partition 5.
[0028] Example 2: Based on Example 1, in order to facilitate the pressing of the pressure block 14 against the lower partition plate 5, a pressure rod 13 is fixedly connected to the end of the elastic element 8 away from the supporting cylinder 6. The inner wall of the pressure rod 13 is movably connected to the pressure block 14. The pressure rod 13 and the pressure block 14 cooperate to ensure that the pressure block 14 rotates to always reach a horizontal position against the lower partition plate 5. Multiple movable grooves 9 are opened on the outside of the supporting cylinder 6. Multiple heat storage ceramics 4 are fixed on the inner wall of the insulation layer 2. The outside of the heat storage ceramics 4 is in contact with the outside of the 3. The outside of the lower partition plate 5 is in contact with the outside of the heat storage ceramics 4. The outside of the pressure rod 13 is slidably connected to the inner wall of the supporting cylinder 6. The outside of the supporting cylinder 6 is fixedly connected to the inner wall of the outer shell steel plate 1.
[0029] By pulling the lever 10 to adjust the pressure rod 13 to a suitable angle, pressure is applied to the lower partition plate 5. Under the influence of thermal expansion and contraction, the lower partition plate 5 contracts, creating a gap below. At this time, under the action of the elastic potential energy of the elastic element 8, the pressure rod 13 drives the pressure block 14 in the pressure rod 13 to squeeze the lower partition plate 5. After being squeezed, the lower partition plate 5 moves downward until the gap below is blocked. The pressure block 14 rotates outside the pressure rod 13 and always keeps horizontally attached to the lower partition plate 5, and is not affected by the change of the angle of the pressure rod 13. This ensures that the lower partition plate 5 is always tightly attached to the bottom during contraction and in its initial state, without any gaps.
[0030] Example 3: Based on Example 2, in order to quickly disassemble the lower partition 5, the end of the pressure rod 13 away from the pressure block 14 is movably connected to the outside of the connecting ring 12. The connecting ring 12 is an important component that connects the pressure rod 13 and allows the pressure rod 13 to change its posture. The inner wall of the pull rod 10 is provided with multiple grooves 11, and the inner wall of the supporting cylinder 6 is provided with a sliding groove 7. The outside of the pressure rod 13 is slidably connected to the inner wall of the movable groove 9. The end of the pressure rod 13 away from the pressure block 14 is slidably connected to the inner wall of the groove 11. The outside of the pull rod 10 is slidably connected to the inner wall of the sliding groove 7. The end of the pressure block 14 away from the pressure rod 13 is in contact with the outside of the lower partition 5.
[0031] When it is necessary to disassemble and maintain the lower partition plate 5, press the pull rod 10, so that the contact surface between the pressure rod 13 and the movable groove 9 is used as the fulcrum to swing, and the connecting ring 12 in the pull rod 10 is used as the connection point. Under the influence of these factors, the pressure block 14 moves away from the lower partition plate 5, so that the pressure rod 13 and the supporting cylinder 6 are in a V-shape. At this time, the lower partition plate 5 can be taken out, and the lower partition plate 5 can be quickly disassembled, replaced and maintained.
[0032] The working process of this utility model is as follows:
[0033] First, by pulling the lever 10 to adjust the pressure lever 13 to a suitable angle, pressure is applied to the lower partition plate 5. Due to thermal expansion and contraction, the lower partition plate 5 contracts, creating a gap below. Then, under the elastic potential energy of the elastic element 8, the pressure lever 13 drives the pressure block 14 within it to squeeze the lower partition plate 5. This squeezes the lower partition plate 5 downwards until the gap is blocked. The pressure block 14 rotates outside the pressure lever 13, always remaining horizontally aligned with the lower partition plate 5, and its compression is unaffected by changes in the angle of the pressure lever 13. The design ensures that the partition plate 5 remains tightly attached to the bottom during shrinkage and in its initial state without any gaps. When the partition plate 5 needs to be disassembled for maintenance, pressing the pull rod 10 causes the pressure rod 13 to swing with the contact surface between it and the movable groove 9 as the fulcrum. Under the influence of the connecting ring 12 in the pull rod 10 as the connection point, the pressure block 14 moves away from the partition plate 5, causing the pressure rod 13 and the supporting cylinder 6 to form a V-shape. At this point, the partition plate 5 can be removed, enabling quick disassembly, replacement, and maintenance of the partition plate 5.
