It has good air permeability, high dust collection rate, and is easy to clean. The dust removal efficiency can reach 98.99%. It has good PM2.5 removal performance and has certain acid, alkali and heat resistance.

[0003] A dust filter bag disclosed in announcement number CN207520770U includes a cylindrical cloth bag, which includes a base cloth layer and a filter layer. The base cloth layer is a glass fiber base cloth layer, and the filter layer is a polytetrafluoroethylene fiber mesh layer. The total thickness of the base cloth layer and the filter layer is 1.2 mm. The filter layer is coated with a Teflon coating, and a cylindrical heat insulation sleeve is provided at the bottom of the cloth bag. The heat insulation sleeve is woven from flame-retardant fiber fabrics and interspersed with supersilicon threads, and the heat insulation sleeve is coated with a composite silicate heat insulation coating.

[0004] However, the above scheme still has the following problems during use: during use, the dust filter bag is just a simple cylindrical structure, and the surface area of ​​the cylinder is the filtration area, which makes its effective filtration area small, resulting in low effective filtration efficiency of the dust filter bag during actual use.

[0005] Therefore, we proposed dust filter bags with large filtering area to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a dust filter bag with a large filtering area to solve the problem of the existing dust filter bags on the market proposed in the above background technology. The dust filter bags are just simple cylindrical structures, and the surface area of ​​the cylinder is the filtering area, which makes the effective filtering area small, resulting in the dust filter bags having low effective filtering efficiency when actually used.

[0007] To achieve the above purpose, the utility model provides the following technical solutions: a dust removal filter bag with a large filtering area comprises a dust removal bag body, and a matching filter bag frame is arranged outside the dust removal bag body for use in conjunction;

[0008] It also includes: the dust bag body is made of cloth, and a hard port is installed on the top of the dust bag body, and the port is engaged with the notch on the top of the filter bag frame, and the dust bag body is located inside the filter bag frame, and a first spring is installed on the notch at an equal angle;

[0009] The dust bag body is configured to have a multi-fold shape, and the dust bag body as a whole is configured to be a cylindrical structure with a serrated edge structure.

[0010] Preferably, spring wires are installed at the folds of the dust removal bag body, and the spring wires are distributed at equal intervals in the transverse and longitudinal directions, and the spring wires open the folds to filter dust.

[0011] Preferably, latches are symmetrically connected to the left and right sides of the top of the filter bag frame, and a second spring is installed between the latch and the filter bag frame, and the end of the latch is plugged into the slot, and the slot is correspondingly opened on the outside of the port.

[0012] Preferably, the dust bag body forms a convenient disassembly and assembly structure through a latch and a slot, and the end of the latch is arranged as a hemispherical structure, and the port is squeezed and misaligned with the end of the latch during installation.

[0013] Preferably, a motor is installed at the inner bottom of the filter bag frame, and the output end of the motor is connected to a large gear, and the large gear bearing is connected to the inner side of the bottom of the filter bag frame.

[0014] Preferably, a pinion is meshed and connected to the outer side of the large gear at an equal angle, and a bearing of the pinion is connected to the inner side of the bottom of the filter bag frame, and a lever is integrally installed on the top of the pinion.

[0015] Preferably, the lever is configured as a cam-shaped structure, and a rotation radius of the lever is greater than a distance from the lever to the outside of the dust bag body.

[0016] Compared with the prior art, the utility model has the following beneficial effects: when in use, the pleated arrangement can expand the use area to a larger extent, so that more dust can be filtered and processed, thereby improving the efficiency of dust removal and filtration, and the dust bag body can be conveniently disassembled and replaced when in use, and a flapping structure is arranged inside the filter bag frame, so as to effectively shake off the dust adhering to the side wall of the dust filter bag, thereby ensuring the overall dust removal effect of the dust filter bag, and the specific contents are as follows:

[0017] 1. By setting the spring wire, the folds of the dust bag body can be stretched open, thereby expanding the effective filtering area of ​​the dust bag. Compared with the simple cylindrical structure, the filtering area is larger, thereby improving the filtering efficiency of the dust bag body;

[0018] 2. Through the setting of the latch and the slot, the dust bag body can be easily replaced. After pulling the latch, the second spring will be compressed and separated from the slot, and the first spring will push the dust bag body out of the notch, making it easier to replace. During installation, the processing port is pressed into the notch, and the latch will engage with the slot again to complete the installation operation;

[0019] 3. Through the setting of the lever, when there is a lot of dust in the later stage, the dust bag body can be patted to improve the shaking effect of the dust filter bag, so as to effectively shake off the dust adhering to the side wall of the dust filter bag, thereby ensuring the overall dust removal effect of the dust filter bag;

[0020] Furthermore, after the motor drives the large gear to rotate, the large gear will drive the small gear to rotate, and after the small gear rotates, it will drive the lever to rotate synchronously, thereby beating the dust bag body;

[0021] Furthermore, the lever is configured as a cam-shaped structure, and the rotation radius of the lever is greater than the distance from the lever to the dust bag body, so that after the lever rotates, the dust bag body is intermittently slapped, thereby accelerating the shaking off of dust.
