DETAILED DESCRIPTION
[0022] In order to facilitate the understanding of those skilled in the art, the utility model is further described in detail in combination with the drawings and specific embodiments.
[0023] As Figures 1-6 The inner skeleton of the filter cartridge comprises a net tube-shaped frame body 1, the inner wall of the frame body 1 is provided with at least two reinforcing vertical ribs 11, and the reinforcing vertical ribs 11 are provided with mounting grooves 111 for matching with the dust collector support frame 3. The dust collector support frame 3 cooperates with the mounting grooves 111, thereby realizing the fixation of the filter cartridge, and the positioning effect is good. Long-term use can make the filter cartridge maintain the shape and not deviate from the position, and the use effect is better. And the dust collector support frame 3 can support the reinforcing vertical ribs 11, thereby supporting the frame body 1, and the structure of the frame body 1 is more stable, thereby better supporting the pleated filter material of the filter cartridge, and making the overall structure of the filter cartridge more stable. The mounting grooves 111 are U-shaped, and the direction of the groove opening of the mounting grooves 111 is towards the axis of the frame body 1. This structure facilitates the clamping of the mounting grooves 111 and the dust collector support frame 3. In addition, the dust collector support frame 3 is directly matched and fixed with the mounting grooves 111 during the installation of the filter cartridge, and the mounting grooves 111 can be matched and fixed, and the adaptability is good, which can be suitable for various dust collectors. The reinforcing vertical ribs 11 are provided with 2-5 reinforcing vertical ribs 11, and are non-uniformly arranged in the inner wall of the frame body 1.

Each horizontal rib 12 is non-equally wide, and the spacing between the horizontal ribs 12 is also non-equally spaced. Each vertical rib 13 is non-equally wide, and the spacing between the vertical ribs 13 is also non-equally spaced. The horizontal ribs 12 and the vertical ribs 13 have a plurality of width specifications. The wider horizontal ribs 12 and vertical ribs 13 can provide stronger support, while the narrower horizontal ribs 12 and vertical ribs 13 can provide supplementary support, and can reduce the shielding area and increase the ventilation area. Therefore, the above structure can make the frame body 1 have sufficient support strength, meet the requirements of overall support strength and local support strength, and increase the ventilation area as much as possible and reduce the influence on the filtering area. The cross sections of the horizontal ribs 12 and the vertical ribs 13 are all trapezoidal with a narrow outside and a wide inside. This structure can reduce the backflow resistance when the filter cartridge is cleaned and enhance the cleaning effect.
[0025] The filter cartridge with the inner skeleton further comprises conductive modules 2, which are arranged at both ends of the reinforcing vertical rib 11 and used to contact the folded paper filter material of the filter cartridge. The conductive modules 2 are in communication with the dust collector, so that the dust on the folded paper filter material can be conducted and the dust static electricity can be removed, especially for the explosive dust, the risk of explosion can be reduced. The conductive module 2 comprises a conductive block 21, the end of the reinforcing vertical rib 11 is provided with an embedding hole 112, and the conductive block 21 is embedded in the embedding hole 112, so that the installation is convenient. The conductive block 21 is made of a non-metallic conductive material, such as a conductive polymer or graphene, and is convenient for recycling and processing. The end surface of the reinforcing vertical rib 11 is provided with a fixing hole 113 in communication with the embedding hole 112, the fixing hole 113 is provided with a conductive bolt 22 screwed in the conductive block 21, the conductive bolt 22 is connected with a conductive wire 23, the conductive wire 23 is used to connect the dust collector, and the dust static electricity of the folded paper filter material is sequentially conducted out through the conductive block 21, the conductive bolt 22 and the conductive wire 23.
[0026] As shown in Figure 7 The frame body 1 is installed in the folded paper filter material 4 during production of the filter cartridge, and plays a supporting role on the folded paper filter material 4, and the end is fixed by the end cover 5.
[0027] The above embodiment is a preferred implementation manner of the utility model, and is not a limitation on the utility model. Without departing from the utility model concept of the utility model, any obvious replacement is within the protection scope of the utility model.
