Description
Technical Field
[0001] This utility model relates to the field of filter bag frames, specifically a dust collector filter bag frame reinforced with horizontal ribs by spot welding to prevent detachment. Background Technology
[0002] In existing dust collector filter bag cage applications, traditional cage structures present several problems when installing dust collector bags. Firstly, the connection between the horizontal and vertical ribs is not robust enough. Relying solely on conventional connection methods, the horizontal ribs are prone to detaching from the vertical ribs during long-term use due to vibrations from the dust collector and the stretching of the filter bag. This not only affects the overall structural stability of the cage but also reduces the service life and dust collection efficiency of the filter bag. Secondly, the filter bag is not securely installed on the cage, making it prone to detachment.
[0003] Existing installation methods are difficult to effectively secure dust collector bags. During the dust removal process, the scouring of dust-laden gas and the vibration generated by the operation of the equipment may cause the dust collector bags to slip off the frame, thereby affecting the normal operation of the entire dust removal system and increasing the maintenance costs and downtime of the equipment.
[0004] Therefore, a new type of dust collector filter bag frame structure is needed to solve the above problems and improve the stability of the frame and the firmness of the dust collector bag installation. Utility Model Content
[0005] The purpose of this invention is to provide a cross-ribbed, spot-welded reinforced dust collector filter bag frame to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust collector filter bag frame reinforced with spot welding of horizontal ribs, comprising a top frame and a bottom frame. Multiple vertical ribs are fixed on the inner side between the top frame and the bottom frame. Multiple horizontal ribs are fixed on the inner side of the multiple vertical ribs. Elastic hoops are fitted on the outer side of the multiple vertical ribs. Multiple limiting clips are provided on the inner side of the elastic hoops. After the dust collector filter bag is fitted on the outer side of the multiple vertical ribs, the elastic hoops are fitted on the outer side of the dust collector filter bag. The limiting clips are inserted into the outer ring surface of the horizontal ribs, and the dust collector bag is clamped between the horizontal ribs and the limiting clips.
[0007] Preferably, the contact points between the horizontal and vertical ribs are spot welded on both the upper and lower sides.
[0008] Preferably, the outer ring surface of the transverse rib is provided with a slot, which is an annular groove with a circular arc-shaped cut. The slot matches the limiting clip, that is, the limiting clip clamps the dust collector bag in the slot.
[0009] Preferably, the elastic hoop includes a rubber sleeve, and a limiting clip is installed on the inner ring surface of the rubber sleeve. Multiple limiting clips are provided, and the limiting clips and vertical ribs are distributed alternately, that is, the limiting clips are inserted into the slots between two adjacent vertical ribs.
[0010] Preferably, the limiting clip includes a plastic insert and a rubber clip sleeved and fixed to one side of the plastic insert. One end of the plastic insert is fixed to the inner ring surface of the rubber sleeve, and one side of the plastic insert and the rubber clip are inserted into the slot. The rubber clip is a long strip with a circular arc cross-section.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model proposes a cross-rib reinforced dust collector filter bag cage with spot welding. A groove is formed on the outer ring surface of the cross-rib, and a matching limiting clip is installed. The limiting clip is installed on the inner ring surface of the elastic hoop (rubber sleeve). After the dust collector bag is fitted onto the cage, the elastic hoop is fitted onto the outside of the dust collector bag, and the limiting clip is inserted into the groove. At this time, the dust collector bag is partially clamped in the groove. This installation method can firmly fix the dust collector bag to the cage, effectively preventing the dust collector bag from falling off during use, ensuring the normal operation of the dust collection system, and reducing equipment maintenance costs and downtime.
[0012] The limiting clip includes a plastic insert and a rubber clip fixed to one side of the plastic insert. The rubber clip is a long strip with a rounded cross-section. This design allows the rubber clip to better fit into the slot when the limiting clip is inserted, increasing friction and further improving the clamping effect on the dust collector bag. At the same time, the rounded surface design of the rubber clip also reduces damage to the dust collector bag, protecting its integrity.
[0013] During installation, simply slip the dust collector bag onto the frame from bottom to top, secure the top, then expand and deform the rubber sleeve before slipping it over the outside of the dust collector bag. Adjust the height to align with the horizontal ribs, then move the rubber sleeve to position the limiting clips appropriately. Finally, push the rubber sleeve to insert the limiting clips into the slots. The entire installation process is simple and convenient, easy to master, and the position of the rubber sleeve can be adjusted according to actual conditions to ensure optimal installation results.
[0014] By spot welding on both the top and bottom sides at the contact points of the horizontal and vertical ribs, the connection between the vertical and horizontal ribs is effectively strengthened. This spot welding reinforcement method can significantly improve the overall structural strength of the frame, prevent the horizontal ribs from falling off the vertical ribs, ensure the frame remains stable during long-term use, thereby providing reliable support for the dust collector bag and extending the service life of the dust collector filter bag frame.

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] Please see Figures 1-7 This utility model provides a technical solution: a dust collector filter bag frame reinforced with spot welding of horizontal ribs, including a top frame 1 and a bottom frame 2. Multiple vertical ribs 3 are fixed on the inner side between the top frame 1 and the bottom frame 2. Multiple horizontal ribs 4 are fixed on the inner side of the multiple vertical ribs 3. The contact points of the horizontal ribs 4 and the vertical ribs 3 are spot welded on both the upper and lower sides to reinforce the connection between the vertical ribs 3 and the horizontal ribs 4 and prevent the horizontal ribs 4 from falling off the vertical ribs 3. Elastic hoops are fitted on the outer side of the multiple vertical ribs 3. Multiple limiting clips are provided on the inner side of the elastic hoops. After the dust collector filter bag is fitted on the outer side of the multiple vertical ribs 3, the elastic hoops are fitted on the outer side of the dust collector filter bag. The limiting clips are inserted into the outer ring surface of the horizontal ribs 4, and the dust collector bag is clamped between the horizontal ribs 4 and the limiting clips to prevent the dust collector bag from falling off.
[0018] To ensure the dust collector bags are securely mounted on the frame, the following proposed method is used: The outer ring surface of the horizontal rib 4 is provided with a slot 401. The slot 401 is an annular groove with a circular arc cross-section. The slot 401 matches the limiting clip, that is, the limiting clip clamps the dust collector bag in the slot 401. The elastic hoop includes a rubber sleeve 5. The limiting clip is installed on the inner ring surface of the rubber sleeve 5. There are multiple limiting clips. The limiting clips and the vertical ribs 3 are distributed alternately. That is, the limiting clips are inserted into the slot 401 between two adjacent vertical ribs 3. The limiting clip includes a plastic insert 6 and a rubber clip 7 that is sleeved and fixed on one side of the plastic insert 6. One end of the plastic insert 6 is fixed to the inner ring surface of the rubber sleeve 5. One side of the plastic insert 6 and the rubber clip 7 are inserted into the slot 401. The rubber clip 7 is a long strip with a circular arc cross-section.
[0019] First, the dust collector bag is placed on the frame from bottom to top. Then, the top of the dust collector bag is fixed to the top frame 1 with wire. The rubber sleeve 5 is then expanded and deformed and placed on the dust collector bag on the outside of the frame. The height of the rubber sleeve 5 is adjusted so that the rubber sleeve 5 corresponds to the horizontal rib 4. The rubber sleeve 5 rebounds and is tightly fitted on the dust collector bag. The rubber sleeve 5 is then moved so that the plastic insert 6 and the rubber clip 7 are between two adjacent vertical ribs 3. Then, the rubber sleeve 5 is pushed so that the plastic insert 6 and the rubber clip 7 are inserted into the slot 401. At this time, the dust collector bag is partially clamped in the slot 401, thereby strengthening the connection of the dust collector bag on the horizontal rib 4.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
