[0026] See also Figures 1 to 4 , the utility model provides a technical solution:

[0027] A high-efficiency dust removal filter material fixed keel 2 structure, comprising a bottom frame 1, and four fixed keels 2 fixedly installed on the top of the bottom frame 1, the top of the fixed keel 2 is fixedly connected with a fixed frame 3, and the bottom frame 1 and the fixed frame 3 are provided with positioning components for fixing the dust bag;

[0028] The positioning assembly includes a snap ring 4 movably arranged on the fixed frame 3, a snap groove 5 matched with the snap ring 4 is provided on the top of the fixed frame 3, a mounting frame 6 is fixedly connected to the side of the fixed frame 3, a pull rod 7 is movably provided inside the mounting frame 6, a fixing groove 8 matched with the end of the pull rod 7 is provided on the side of the snap ring 4, a through hole matched with the pull rod 7 is provided at the opening of the dust bag, so that the pull rod 7 can be engaged with the fixing groove 8 through the through hole, a guide ring 9 is fixedly connected to the outer surface of the pull rod 7, a resisting spring 10 is fixedly connected to the side of the guide ring 9, and the end of the resisting spring 10 is fixedly connected to the inner wall of the mounting frame 6, and a limiting component for limiting the dust bag is provided on the bottom frame 1;

[0029] Specifically, Figure 1 As shown, the cross sections of the bottom frame 1 and the fixed frame 3 are both rectangular, and the bottom frame 1 and the fixed frame 3 have the same area.

[0030] By adopting the above technical solution, when installing the dust bag, the opening of the dust bag is flipped over so that the dust bag can cover the top of the fixed frame 3. Then, the pull rod 7 is pulled outward so that the pull rod 7 can compress the resistance spring 10 through the guide ring 9. Subsequently, the snap ring 4 is engaged in the slot 5, so that the opening of the dust bag can be clamped and fixed. Finally, the pull rod 7 is released so that the pull rod 7 can be engaged with the fixing slot 8 on the snap ring 4 under the elastic force of the resistance spring 10, so that the opening of the dust bag can be fixed.

[0031] The limiting component includes a positioning frame 11 fixedly mounted on the top of the bottom frame 1 , an adjusting screw 12 is connected to the inner thread of the positioning frame 11 , and a pressing plate 13 is movably provided at the end of the adjusting screw 12 .

[0032] Specifically, Figure 1 As shown, there are four groups of limiting components, and the four groups of limiting components are distributed in a cross shape.

[0033] By adopting the above technical solution, the lower end of the dust bag is placed on the top of the bottom frame 1. Then, by rotating the adjusting screw 12, the adjusting screw 12 can drive the clamping plate 13 to move until the bottom of the clamping plate 13 can be clamped and fixed to the top of the dust bag to ensure that it will not loosen during the filtering process. At the same time, the dust bag can be opened to the maximum state to improve the dust removal efficiency of the dust bag.

[0034] Specifically, Figure 4 As shown, a side surface of the pressing plate 13 is fixedly connected to a limiting block 14 , and an inner wall of the positioning frame 11 is provided with a limiting groove matched with the limiting block 14 .

[0041] Working principle: When installing the dust bag, flip the opening of the dust bag so that the dust bag covers the top of the fixed frame 3. Then, pull the pull rod 7 outward so that the pull rod 7 compresses the resistance spring 10 through the guide ring 9. Subsequently, engage the snap ring 4 in the slot 5 to clamp and fix the opening of the dust bag. Finally, release the pull rod 7 so that the pull rod 7 engages with the fixing slot 8 on the snap ring 4 under the elastic force of the resistance spring 10, thereby fixing the opening of the dust bag. Then place the lower end of the dust bag on the top of the bottom frame 1. Turn the adjusting screw 12 so that the adjusting screw 12 drives the clamping plate 13 to move until the bottom of the clamping plate 13 is clamped and fixed to the top of the dust bag, so that the dust bag can perform efficient dust removal.
