Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dust collector technology, and specifically relates to a bag cage for a bag dust collector. Background Technology
[0002] Filter bags possess excellent chemical stability and heat resistance, representing the highest performance in the filter media industry and the most advanced type of commonly used filter material, achieving high levels of filtration efficiency and precision. Commonly used filter media include PE, PP, PTFE, PMIA, and NMO. Filter bags are typically mounted on bag cages, which are then fixed to the dust collection equipment.
[0003] The existing bag cage structure includes a fixed plate and multiple support rods evenly distributed around the fixed plate. Each support rod is a relatively long steel bar. The bag cage has the following drawbacks after fabrication:
[0004] 1. Disadvantages include low stiffness and easy bending;
[0005] 2. Due to its long length, it occupies a significant amount of space during storage and transportation;
[0006] 3. The length is fixed and inconvenient to adjust. Utility Model Content
[0007] The purpose of this utility model is to provide a bag cage for a bag filter to solve the above-mentioned problems.
[0008] The technical solution adopted by this utility model is: a bag cage for a bag dust collector, comprising multiple independent units and an adjusting connector connecting two of the units;
[0009] The unit includes circular fixing plates located on the upper and lower sides and a plurality of support rods evenly distributed around the axes of the two fixing plates.
[0010] The two fixing plates are each provided with through holes, and the through holes are spaced apart from the support rods;
[0011] The adjusting connector includes a lead screw, the upper and lower ends of which respectively penetrate through holes in the nearest fixing plates of the two individual units. Each fixing plate has a nut on its upper and lower surfaces. Loosening the nuts allows adjustment of the length of the lead screw between the two individual units.
[0012] The bottom of the lowest unit is fitted with a base plate via a threaded connector.
[0013] Furthermore, the maximum outline dimension of the nut component of the adjusting connector and the threaded connector is smaller than the ring width dimension of the fixing plate.
[0014] This plan has the following beneficial effects:
[0015] 1. This solution consists of multiple independent units connected by adjustable connectors, which, after assembly, have the characteristics of high rigidity and resistance to bending;
[0016] 2. Because the individual units are short in length, they are easy to transport after being disassembled and do not take up a lot of space;
[0017] 3. The overall length can be adjusted by adjusting the connectors, making it convenient to make length adjustments to suit different situations and provide more suitable support for the bag. Attached Figure Description

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0030] Please see Figures 1 to 3 A bag filter cage includes multiple independent units 1 and an adjusting connector 2 connecting two units 1;
[0031] The unit 1 includes a circular fixing plate 11 located on the upper and lower sides and a plurality of support rods 12 evenly distributed around the axis of the two fixing plates 11. As can be seen in the figure, the fixing plate 11 has a through hole in the center, that is, the fixing plate 11 has a ring-shaped structure.
[0032] Two fixing plates 11 are respectively provided with through holes 11a, and the through holes 11a and the support rods 12 are spaced apart;
[0033] The adjusting connector 2 includes a lead screw 21. The upper and lower ends of the lead screw 21 pass through the through holes 11a on the nearest fixing plates 11 of the two individual units 1 respectively (i.e., connecting the top fixing plate 11 of the next individual unit 1 and the bottom fixing plate 11 of the previous individual unit 1). Each fixing plate 11 has a nut 22 on its upper and lower surfaces. Loosening the nut 22 can adjust the length of the lead screw 21 between the two individual units 1.
[0034] The bottom of the lowest unit 1 is fitted with a base plate 3 via a threaded connector 4. This structure has the following advantages:
[0035] 1. This solution consists of multiple independent units connected by adjustable connectors. Compared with the traditional single long steel bar structure, this solution has the characteristic of relatively high rigidity after assembly.
[0036] 2. Because the individual units are short in length, they are easy to transport after being disassembled and do not take up a lot of space;
[0037] 3. The overall length can be adjusted by adjusting the connectors, making it convenient to make length adjustments to suit different situations and provide more suitable support for the bag.
[0038] Since the cloth bag is placed on the outside of the bag cage, in order not to affect the insertion operation, the maximum outline dimension of the nut component of the adjusting connector 2 and the threaded connector 4 is smaller than the ring width dimension of the fixing plate 11.
[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
