[0025] Such as Figures 1-5As shown, a filter bag support frame comprises a bottom frame 1 and a top frame 4, a plurality of connecting frames 3 are connected between the bottom frame 1 and the top frame 4, a plurality of split support frames 5 are movably arranged between the bottom frame 1 and the top frame 4, a slide groove 501 is provided on one side of the split support frame 5, a slider 502 is slidably arranged inside the slide groove 501, an adjusting member 6 for adjusting the position of the split support frame 5 is arranged on the bottom frame 1 and the top frame 4, a fixing block 2 is arranged at the middle of the top end of the bottom frame 1, the adjusting member 6 comprises a screw rod 601 rotatably arranged at the top end of the fixing block 2, a connecting block 603 is threadedly sleeved on the screw rod 601, a first connecting rod 604 is hinged to each of the four sides of the connecting block 603, a second connecting rod 605 is hinged to each of the four sides of the fixing block 2, the first connecting rod 604 and the second connecting rod 605 on the same side are cross-arranged and hingedly connected thereto, one end of the first connecting rod 604 is hinged to the split support frame 5, and the second connecting rod 605 is hinged to each of the four sides of the fixing block 2. One end of the second connecting rod 605 is hinged to the slider 502; specifically, the filter bag is put on the support frame, and then the position of the split support frame 5 can be adjusted through the set adjustment component 6, so that it can expand outward, thereby the folds of the filter bag can be stretched, and then the contact area with the air can be increased, thereby ensuring the filtering efficiency of the air. When replacing the filter bag, adjusting the adjustment component 6 in the opposite direction can make the split support frame 5 gather inward, so that the filter bag can be easily removed and replaced, which is more convenient to use. When the adjustment component 6 is used, rotating the screw rod 601 can drive the connecting block 603 to rise and fall, and the first connecting rod 604 and the second connecting rod 605 are scissor-connected. When the connecting block 603 is raised and lowered, it can drive the split support frame 5 to expand or gather outward, thereby supporting the expansion of the filter bag and also gathering it to facilitate the replacement of the filter bag.

[0026] like Figure 4 As shown, a connecting turntable 602 is provided at the top of the screw rod 601, and the surface of the connecting turntable 602 is coated with a wear-resistant coating; specifically, the wear-resistant coating coated on the surface of the connecting turntable 602 can prevent its surface from becoming rough and rusty due to frequent rotation.

[0027] like Figure 5 As shown, a clamping member 8 for fixing and limiting the filter bag is provided on the top frame 4, and the clamping member 8 includes two arc-shaped hoop frames 801 movably arranged on the outside of the top frame 4, and two mounting plates 802 are provided on the arc-shaped hoop frames 801, and two adjacent mounting plates 802 are connected by connecting bolts 803, and connecting nuts 804 are threadedly sleeved on the connecting bolts 803; specifically, the two arc-shaped hoop frames 801 can be fixed to the top frame 4 by connecting bolts 803 and connecting nuts 804, and the arc-shaped hoop frames 801 can clamp and fix the opening of the filter bag, thereby fixing the filter bag.

[0028] like Figure 2As shown, a fixing plate 7 is provided at the top end of the top frame 4, and four fixing bolts 701 are provided on the fixing plate 7. Specifically, by means of the provided fixing plate 7 and fixing bolts 701, the support frame can be fixed on the filter.

[0029] As Figure 2 shown, the lead screw 601 is frictionally rotatably connected to the top frame 4. Specifically, there is a certain frictional force between the lead screw 601 and the top frame 4. Therefore, after the lead screw 601 is rotated, it will not rotate by itself under the action of the frictional force.

[0030] As Figure 3 shown, the connecting frame 3 and the split support frame 5 are spaced apart between the bottom frame 1 and the top frame 4, and the outer side surface of the split support frame 5 is an arc surface. Specifically, after the split support frame 5 converges inward, the outer surface thereof has the same radian as the outer surface of the connecting frame 3, and is connected to the bottom frame 1 and the top frame 4 to form a cylindrical shape, which is convenient for sleeving the filter bag.

[0031] In summary: After the filter bag is sleeved on the support frame, the position of the split support frame 5 can be adjusted by means of the provided adjusting member 6, so that it can expand outward. Therefore, the wrinkles of the filter bag can be stretched open, and thus the contact area with the air can be increased, thereby ensuring the air filtration efficiency. When replacing the filter bag, adjusting the adjusting member 6 in the reverse direction can cause the split support frame 5 to converge inward, so that the filter bag can be conveniently removed and replaced, and the use is more convenient. When the adjusting member 6 is specifically used, rotating the lead screw 601 can drive the connecting block 603 to move up and down. The first connecting rod 604 and the second connecting rod 605 are in a scissor connection. When the connecting block 603 moves up and down, it can drive the split support frame 5 to expand outward or converge, so that the filter bag can be expanded and supported and can also be converged to facilitate the replacement of the filter bag.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
