Description

Technical Field

[0001] This utility model relates to the field of desulfurization equipment technology, specifically to a high-efficiency, energy-saving dry desulfurization device for electrolytic aluminum. Background Technology

[0002] High-efficiency and energy-saving dry desulfurization equipment for electrolytic aluminum is mainly used to solve the problem of sulfur-containing waste gas generated during the electrolytic aluminum production process. During the electrolytic aluminum production process, the raw materials used will release sulfur dioxide, a harmful gas. The dry desulfurization equipment can effectively adsorb and react to remove sulfur dioxide from the waste gas, so that it meets environmental emission standards.

[0003] The existing technology has the following problems: The existing equipment cannot replace the filter element during use. During the desulfurization process, the filter element removes sulfur dioxide and other impurities from the exhaust gas through adsorption and filtration. As the usage time increases, the surface of the filter element will gradually be covered by pollutants such as sulfur oxides and dust, and its adsorption sites will be occupied, thus reducing its adsorption capacity. If the filter element cannot be replaced, the desulfurization efficiency will continue to decline, leading to an increase in the concentration of pollutants such as sulfur dioxide in the emitted exhaust gas. In addition, the existing equipment cannot squeeze and seal the gap between the connecting pipe and the exhaust pipe. If there is a gap between the connecting pipe and the exhaust pipe and it is not sealed, the sulfur-containing exhaust gas generated during the electrolytic aluminum production process will leak into the surrounding environment. This exhaust gas contains pollutants such as sulfur dioxide, which will not only cause air pollution and affect the surrounding air quality, but may also harm the nearby ecological environment, crop growth, and residents' health.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific implementation methods.

[0017] like Figures 1-2 As shown, this utility model provides a high-efficiency, energy-saving dry desulfurization device for electrolytic aluminum, including an exhaust pipe 1. A threaded ring 4 is threadedly connected to the outer wall of the exhaust pipe 1. A fixing ring 3 is fixedly connected to the upper side of the threaded ring 4. A connecting pipe 2 is fixedly connected to the inner surface of the fixing ring 3. A snap-fit ​​mechanism 6 is provided on the outer wall of the connecting pipe 2. Multiple fixing frames 5 are movably connected through the outer wall of the connecting pipe 2. A filter element 7 is fixedly connected to the inner surface of the fixing frame 5. A slot 8 is provided on the right side of the fixing frame 5. The exhaust pipe 1 serves as an inlet channel for exhaust gas and is connected to the fixing ring 3 via the threaded ring 4. This threaded connection method facilitates installation and disassembly. To facilitate subsequent maintenance and adjustment of the device, the connecting pipe 2, which is fixedly connected to the fixing ring 3, is the key channel for the exhaust gas to enter the desulfurization device. The snap-fit ​​mechanism 6 set on the outer wall of the connecting pipe 2 is used to fix and remove the fixing frame 5. The fixing frame 5 contains the filter element 7, which is a key component of desulfurization and is used to adsorb and filter sulfur dioxide and other impurities in the exhaust gas. The slot 8 opened on the right side of the fixing frame 5 cooperates with the snap-fit ​​mechanism 6 to realize the quick snap-fit ​​and removal of the fixing frame 5, thereby making it possible to replace the filter element 7. The overall structure establishes the basic framework for the exhaust gas to enter the desulfurization device and the filter element to be installed and fixed.

[0018] like Figures 3-4As shown, this utility model provides a technical solution: Preferably, the snap-fit ​​mechanism 6 includes a snap-fit ​​block 61, a knob 62 rotatably connected to the right side of the snap-fit ​​block 61, a worm gear 67 fixedly connected to the left side of the knob 62, a worm wheel 68 meshing with the outer wall of the worm gear 67, a take-up roller 69 fixedly connected to the front side of the worm wheel 68, a steel wire 610 fixedly connected to the outer wall of the take-up roller 69, a movable plate 65 fixedly connected to the other end of the steel wire 610, the outer wall of the movable plate 65 slidably connected to the snap-fit ​​block 61, a plurality of inserts 66 fixedly connected to the left side of the movable plate 65, the outer wall of the inserts 66 movably connected to the slot 8, two fixing posts 63 fixedly connected to the inner surface of the snap-fit ​​block 61, the outer wall of the fixing posts 63 slidably connected to the movable plate 65, a spring 64 sleeved on the outer wall of the fixing posts 63, one end of the spring 64 fixedly connected to the movable plate 65, and the other end of the spring 64 fixedly connected to the snap-fit ​​block 61. When it is necessary to replace the filter element 7... Rotating knob 62 causes the worm gear 67, which is fixedly connected to it, to rotate. Since the worm gear 67 meshes with the worm wheel 68, the rotation of the worm gear 67 drives the worm wheel 68 to rotate. The winding roller 69, which is fixedly connected to the front side of the worm wheel 68, rotates accordingly. The winding roller 69 begins to wind up the steel wire 610. The movable plate 65, connected to the other end of the steel wire 610, slides along the fixed post 63 on the inner surface of the snap block 61 under the tension of the steel wire, compressing the spring 64. At the same time, the insertion post 66 fixed on the left side of the movable plate 65 disengages from the slot 8 on the right side of the fixed frame 5, thereby releasing the fixation of the fixed frame 5. The fixed frame 5, together with the filter element 7, can be removed from the connecting pipe 2 for replacement. During installation, the operation is reversed. The elastic force of the spring 64 pushes the movable plate 65 to reset, and the insertion post 66 inserts into the slot 8, thus fixing the fixed frame 5 and the filter element 7. This mechanism realizes the convenient replacement function of the filter element 7, ensuring that the desulfurization device can replace the filter element 7 in a timely manner and maintain a good desulfurization effect.

[0019] like Figures 5-6As shown, this utility model provides a technical solution: Preferably, a motor 9 is fixedly connected to the outer wall of the fixed ring 3, a bevel gear 10 is fixedly connected to the output shaft of the motor 9, a bevel gear ring 12 is meshed with the outer wall of the bevel gear 10, a rotating ring 11 is fixedly connected to the lower side of the bevel gear ring 12, the outer wall of the rotating ring 11 is rotatably connected to the fixed ring 3, a plurality of limiting plates 13 are fixedly connected to the inner surface of the fixed ring 3, inserts 14 are slidably connected to the outer wall of the limiting plates 13, a connecting rod 15 is fixedly connected to the opposite face of two inserts 14, a plurality of arc-shaped grooves 16 are opened through the upper side of the rotating ring 11, the outer wall of the connecting rod 15 is slidably connected to the arc-shaped grooves 16, a sealing ring 17 is fixedly connected to the inner surface of the fixed ring 3, and the outer wall of the exhaust pipe 1 is movably connected to the sealing ring 17. The outer wall of the sealing ring 17 is movably connected to the insert block 14. When the motor 9 starts, its output shaft drives the bevel gear 10 to rotate. The bevel gear 10 meshes with the bevel gear ring 12, which in turn drives the rotating ring 11 fixedly connected to the lower side of the bevel gear ring 12 to rotate within the fixed ring 3. The arc groove 16 on the rotating ring 11 interacts with the connecting rod 15. When the rotating ring 11 rotates, the connecting rod 15 slides within the arc groove 16, thereby driving the insert block 14 connected to it to slide along the limiting plate 13. The insert block 14 moves towards the exhaust pipe 1, squeezing the sealing ring 17 so that the sealing ring 17 tightly fits against the outer wall of the exhaust pipe 1, achieving a squeeze seal between the connecting pipe 2 and the exhaust pipe 1, preventing the leakage of sulfur-containing waste gas, ensuring that all waste gas enters the desulfurization device for treatment, and effectively reducing environmental pollution.

[0020] The working principle of this high-efficiency, energy-saving dry desulfurization device for electrolytic aluminum will be explained in detail below.

[0021] like Figures 1-5As shown, when the filter element 7 needs to be replaced, turn the knob 62. The knob 62 drives the worm gear 67, which is fixedly connected to it, to rotate. Since the worm gear 67 meshes with the worm wheel 68, the rotation of the worm gear 67 drives the worm wheel 68 to rotate. The winding roller 69, which is fixedly connected to the front side of the worm wheel 68, rotates accordingly. The winding roller 69 begins to wind up the steel wire 610. The movable plate 65, connected to the other end of the steel wire 610, slides along the fixed post 63 on the inner surface of the snap block 61 under the action of the steel wire tension, compressing the spring 64. At the same time, the insertion post 66 fixed on the left side of the movable plate 65 disengages from the slot 8 on the right side of the fixed frame 5, thereby releasing the fixation of the fixed frame 5. The fixed frame 5 and the filter element 7 can be removed from the connecting pipe 2 for replacement. During installation, the operation is reversed. The elastic force of the spring 64 pushes the movable plate 65 to reset, and the insertion post 66 is inserted into the slot 8, realizing the replacement of the fixed frame 5 and the filter element. The fixing of filter element 7 enables convenient replacement of filter element 7, ensuring that the desulfurization device can replace filter element 7 in a timely manner and maintain good desulfurization effect. When motor 9 starts, its output shaft drives bevel gear 10 to rotate. Bevel gear 10 meshes with bevel gear ring 12, thereby driving the rotating ring 11 fixedly connected to the lower side of bevel gear ring 12 to rotate within the fixed ring 3. The arc groove 16 opened on the rotating ring 11 interacts with the connecting rod 15. When the rotating ring 11 rotates, the connecting rod 15 slides within the arc groove 16, thereby driving the connected insert block 14 to slide along the limiting plate 13. The insert block 14 moves towards the exhaust pipe 1, squeezing the sealing ring 17 so that the sealing ring 17 tightly fits the outer wall of the exhaust pipe 1, realizing the compression and sealing of the gap between the connecting pipe 2 and the exhaust pipe 1, preventing the leakage of sulfur-containing waste gas, ensuring that all waste gas enters the desulfurization device for treatment, and effectively reducing environmental pollution.
