Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 A baghouse dust collector for waste gas treatment includes a dust collector housing 1, a filter mechanism 4 inside the dust collector housing 1, an air inlet 11 on the lower side of the outer surface of the dust collector housing 1, and an air outlet 13 on the upper side. A detachable top cover 14 is provided on the top of the dust collector housing 1. A partition circular plate 3 is fixedly installed inside the dust collector housing 1, with its edge fitting against the inner wall of the dust collector housing 1. Three disassembly holes 31 with sealing structures are provided on the partition circular plate 3. The partition circular plate 3 and the disassembly holes 31 are integrally formed and constitute an annular limiting platform. The lateral cross-sectional area of the filter mechanism 4 is larger than that of the disassembly holes 31. The filter mechanism 4 is positioned above the annular limiting platform, and the dust collector bag body 41 is fixedly connected below the filter mechanism 4. During use, the dust collector bag body 41 can be quickly disassembled and assembled through the detachable connection structure, including the disassembly and assembly hole 31 and the elastic and deformable sealing gasket 33. When maintenance is required, the dust collector bag body 41 can be easily lifted and disassembled using the lifting ring 43 for thorough cleaning or direct replacement with a new dust collector bag body 41, thereby ensuring that it is always in good working condition, maintaining efficient filtration and purification capabilities, greatly improving the convenience of equipment maintenance and operating efficiency, and ensuring the quality of waste gas treatment.
[0026] Furthermore, a control panel 12 is provided on the outer surface of the dust collector housing 1. During use, the operator can easily control the operating parameters of the dust collector through the control panel 12, thereby improving the automation level and ease of operation of the equipment.
[0027] Furthermore, the upper cover 14 is installed on the upper end of the dust collector housing 1, and a lifting rod 141 is fixedly connected to the upper surface of the upper cover 14. In use, this design facilitates the disassembly and assembly of the upper cover 14, thereby facilitating the maintenance, replacement or repair of internal components such as the filter mechanism 4. The lifting rod 141 also facilitates the disassembly and assembly of the upper cover 14 by lifting machinery, enhancing the practicality of the equipment.
[0028] Furthermore, a dust hopper 2 is welded to the lower end of the dust collector shell 1. The interior of the dust hopper 2 is connected to the interior of the dust collector shell 1. When in use, the suction device is activated to transport gas from the air inlet 11 to the interior of the dust collector shell 1. After the gas is filtered and purified by the dust collection bag body 41, the dust and impurities contained in it will be collected and stored in the dust hopper 2, thereby ensuring the dust removal effect and environmental cleanliness.
[0029] Furthermore, the lower end of the ash hopper 2 is provided with an ash discharge mechanism 21, and the ash discharge mechanism 21 is provided with a valve 22. In use, the ash discharge mechanism 21 is used to periodically discharge the collected dust, and the valve 22 can control the opening and closing of the ash discharge and the flow rate to prevent dust leakage and secondary pollution, and ensure the dust removal effect.
[0030] Furthermore, the dividing circular plate 3 is also provided with a slot 32, which surrounds the disassembly hole 31. The lower surface of the filter mechanism 4 is provided with a retaining ring 44 that is adapted to the slot 32. The retaining ring 44 is inserted into the slot 32. When in use, the slot 32 and the retaining ring 44 cooperate to further prevent the gas that has not been filtered by the dust collector bag body 41 from leaking out, thereby ensuring the exhaust gas treatment effect.
[0031] Furthermore, an elastic and deformable sealing gasket 33 is fixedly connected to the lower part of the inner wall of the disassembly hole 31. In use, the sealing gasket 33 is specifically made of rubber. By relying on elastic deformation, it can effectively prevent the leakage of gas that has not been filtered by the dust collector bag body 41. At the same time, since its elastic material does not limit the disassembly and assembly of the dust collector bag body 41, it ensures the efficient and stable operation of the dust collector.
[0032] Furthermore, the upper surface of the filter mechanism 4 is provided with several exhaust holes 42. When in use, after the exhaust gas is filtered by the dust collector bag body 41, the clean gas is discharged through the exhaust holes 42 into the upper space inside the dust collector shell 1, and finally discharged from the outlet 13.
[0033] Furthermore, a lifting ring 43 is fixedly connected to the center of the upper surface of the filter mechanism 4. In use, the lifting ring 43 facilitates the hoisting and disassembly of the filter mechanism 4 with the aid of lifting equipment, and makes it convenient to clean, replace or maintain it, thereby improving the ease of operation and work efficiency.
[0034] Working Principle: This utility model discloses a baghouse dust collector for waste gas treatment. During use, gas carrying dust is drawn into the dust collector housing 1 through the inlet 11 using a suction device. The gas passes through the filter mechanism 4 on the dividing circular plate 3, specifically through the dust collection bag body 41 at the lower end of the filter mechanism 4. Dust and impurities in the gas are removed, and the clean gas is discharged through the exhaust port 42 into the upper space inside the dust collector housing 1, and then exits through the outlet 13. The filtered dust falls into the ash hopper 2 and is discharged through the ash discharge mechanism 21. The dust collection bags need to be cleaned. When cleaning the outer surface of the main body 41 or the dust bag body 41, the top cover 14 can be lifted and placed aside using the lifting rod 141, and then the filter mechanism 4 together with the dust bag body 41 can be lifted using the lifting ring 43, so that the slot 32 and the ring 44 are separated, and the sealing gasket 33 will not be limited by deformation. At the same time, the dust bag body 41 has a skeleton inside, and the cloth bag is attached to the outer surface of the skeleton, so the dust bag body 41 will not be deformed, which makes it easy to clean or replace the dust bag body 41, ensuring the filtration and purification effect of the dust bag body 41 and improving the exhaust gas treatment effect.
