Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector technology, and in particular to a novel dust collector bag cage structure. Background Technology
[0002] The bag cage is the rib of the dust collector bag. It should be lightweight, easy to install and maintain. The quality of the frame directly affects the filtration performance and service life of the filter bag. The overall structure should be smooth, flat, and burr-free, with characteristics of corrosion resistance, wear resistance, and high temperature resistance. It should have a service life of more than 3 years. The bag cage can be used to install and fix the filter bag. Due to its simple structure and ease of use, baghouse dust collectors are increasingly widely used in industrial exhaust gas treatment and powder recovery.
[0003] Existing dust collectors often use welded connections between the support frame and connectors, with the weld typically consisting of a single rib. If this weld breaks, it affects the overall adsorption capacity of the entire bag cage, reducing dust collection efficiency. Furthermore, the straight pipe connection at the top of existing bag cages can shorten the lifespan of the filter bags during negative pressure operation. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Example 1:
[0024] Please see Figure 1-4 This utility model provides an embodiment:
[0025] A novel dust collector bag cage structure includes a bag cage structure body 1, which includes vertical support plates 3, a bag cage bottom 4, a bag cage top 5, and outer ring reinforcing ribs 6. Multiple vertical support plates 3 are arranged equidistantly around the center of a circle, and the two ends of the multiple vertical support plates 3 are respectively connected to the bag cage bottom 4 and the bag cage top 5. The multiple vertical support plates 3 form a circular structure. Multiple equidistant outer ring reinforcing ribs 6 are provided on the outer surface of the vertical support plates 3, and the outer ring reinforcing ribs 6 are fixedly welded to the outer surface of the multiple vertical support plates 3.
[0026] In this implementation plan: by arranging the vertical support plates 3 around the center and welding multiple outer ring reinforcing ribs 6 on the outside, the denser the arrangement of the reinforcing ribs, the higher the strength of the bag cage structure, which can improve the overall stability of the dust collector bag cage structure. This arrangement can greatly improve the strength of the dust collector bag cage structure, thereby preventing the bag cage from breaking at the welded joints during use.
[0027] In this embodiment, in order to further improve the strength, the vertical support plate 3 is welded around the center to the inner position of the outer ring reinforcing rib 6. The outer ring reinforcing rib 6 is welded horizontally to the surface of multiple vertical support plates 3. The multiple outer ring reinforcing ribs 6 and the multiple vertical support plates 3 are arranged in a cross pattern. The structural rigidity of the bag cage can be improved by the equidistant arrangement of the outer ring reinforcing ribs 6.
[0028] In this embodiment, the vertical support plate 3 has multiple horizontally arranged inner ring reinforcing ribs 2 welded at equal intervals around the center. The thickness of the inner ring reinforcing ribs 2 is preferably 1mm, which can not only improve the strength of the bag cage, but also improve the overall stability of the bag cage and reduce the operating resistance of the dust collector.
[0029] In this embodiment, multiple inner ring reinforcing ribs 2 and outer ring reinforcing ribs 6 are arranged horizontally at equal intervals, and the inner ring reinforcing ribs 2 and outer ring reinforcing ribs 6 are sequentially stacked and welded on the inner and outer rings of the vertical support plate 3.
[0030] In this embodiment, the spacing between adjacent outer reinforcing ribs 6 should preferably be 300mm-350mm to reduce running resistance and energy consumption.
[0031] In this embodiment, through holes 7 are provided on the surface of the vertical support plate 3 to improve gas flow and ensure the dust removal efficiency of the bag cage structure.
[0032] Through the above steps, multiple vertical support plates 3 are arranged equidistantly around the center during use. The two ends of the multiple vertical support plates 3 are respectively connected to the bottom 4 and top 5 of the bag cage. The multiple vertical support plates 3 form a circular structure. Multiple equidistant outer ring reinforcing ribs 6 are provided on the outer surface of the vertical support plates 3. The outer ring reinforcing ribs 6 are fixedly welded to the outer surface of the multiple vertical support plates 3. The denser the arrangement of the reinforcing ribs, the higher the strength of the bag cage structure, which can improve the overall stability of the dust collector bag cage structure. This arrangement can greatly improve the strength of the dust collector bag cage structure. In order to further improve the strength, the outer ring reinforcing ribs 6 are horizontally welded to the surface of the multiple vertical support plates 3 to improve the structural hardness of the bag cage. Inner ring reinforcing ribs 2 are welded to the inner ring of the vertical support plates 3. The thickness of the inner ring reinforcing ribs 2 should be 1mm. This not only improves the strength of the bag cage, but also improves the overall stability of the bag cage and reduces the operating resistance of the dust collector.
[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
