Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector bag technology, specifically to a corrugated pleated dust collector bag. Background Technology
[0002] In modern industrial waste gas treatment and environmental protection, baghouse dust collectors are widely used as highly efficient dust separation devices in various fields. The key structure of a baghouse dust collector—the filter bag—is the core component for achieving gas purification. During operation, polluted air carrying dust particles enters the dust collector. As it passes through the filter bag, the solid particles are trapped on the surface of the bag, while the cleaned gas is discharged through the bag, achieving effective removal of harmful particulate matter.
[0003] However, in existing dust removal technologies, the surface of dust collector bags is often designed with corrugated pleats to improve filtration efficiency and dust adsorption capacity. The initial intention of this design was to increase the effective filtration area of the bag surface, thereby increasing the gas processing capacity and dust adsorption volume per unit time. But in practice, this pleated structure has brought about a series of problems.
[0004] As the dust removal process continues, the external dust-laden gas constantly impacts the surface of the filter bags. Combined with the frequent vibration and friction of the bags during pulse cleaning, electrostatic effects easily arise between the bag materials and between the bags and the tiny particles in the gas. This static electricity not only intensifies the adhesion between dust particles and the bag surface, causing dust to adhere more tightly to the bag's folds, but can also lead to the formation of a difficult-to-remove electrostatic film on the bag surface. This film makes it difficult for the adsorbed dust to be blown off by the pulse airflow. Even if some dust is blown off, it is easily adsorbed back onto the bag surface due to static electricity, severely affecting dust removal efficiency and the service life of the filter bags.
[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0006] In view of the problems in the related technologies, this utility model proposes a corrugated dust collector bag to overcome the above-mentioned technical problems existing in the existing related technologies.
[0007] Therefore, the specific technical solution adopted by this utility model is as follows:
[0008] A corrugated dust collector bag includes a bag body, a support frame fixedly installed inside the bag body, a positioning frame fixedly connected to the bottom of the support frame, a drive shaft rotatably mounted on the surface of the positioning frame, a driven fan fixedly connected to one end of the drive shaft, a drive frame fixedly connected to the other end, a support column fixedly connected to the outer surface of the drive frame, a cleaning roller rotatably mounted on the surface of the support column, a reinforcing rod fixedly connected to one side of the support frame, a high-pressure generator fixedly mounted on one side of the bottom surface of the reinforcing rod, and an ionizer fixedly mounted on one side of the high-pressure generator.
[0009] Furthermore, in order to enable the bag body to be fixedly installed on the surface of the support frame, positioning rings are fixedly connected to both ends of the support frame. The surface of the positioning rings is provided with clamping rings. Both the surface of the positioning rings and the clamping rings are provided with connecting holes. The two ends of the bag body are fixedly clamped between the positioning rings and the clamping rings.
[0010] Furthermore, in order to increase the filtration efficiency of the bag body, the outer surface of the bag body is provided with wave-shaped pleats.
[0011] Furthermore, to facilitate the fixed installation of the support frame and the filter bag body inside the dust collector, mounting rods are fixedly connected to both sides of the inner wall of the positioning ring, and threaded holes are opened at the ends of the mounting rods.
[0012] Furthermore, in order to enhance the static elimination capability of the bag body, a grounding wire is rotatably connected to the bottom of the transmission shaft.
[0013] Furthermore, in order to reduce the impact of pulsed gas blowing into the bag body on the ion bar, buffer slopes are opened on both sides of the top of the reinforcing rod.
[0014] Furthermore, in order to achieve high dust filtration efficiency for both the bag body and the corrugated pleats, both the bag body and the corrugated pleats are made of polyester fiber.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. During operation, the internal ion air bar of the filter bag continuously blows out airflow carrying positively charged electrons to neutralize the charge on the surface of the filter bag, thereby eliminating static electricity on the filter bag and effectively suppressing the generation of static electricity on the filter bag surface. This not only reduces the situation where dust is tightly adsorbed on the filter bag, but also avoids the problem of dust being attracted by static electricity again during pulse cleaning, greatly improving cleaning efficiency.
[0017] 2. The corrugated design on the bag body increases the effective filtration area of the bag. When the surface of the bag body needs cleaning after it has absorbed dust in the dust collector, a pulsed airflow is generated inside the dust collector and blows it into the bag body and the supporting frame. The high-speed flow of the pulsed airflow can drive the driven fan and the transmission frame to rotate, which in turn drives the cleaning roller on the outside of the bag body to rotate continuously. This continuously impacts and cleans the surface of the bag body, causing the dust on the surface of the bag body to fall off quickly. This makes it easier for the dust to be blown off by the pulsed airflow, thus effectively enhancing the cleaning effect. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] According to an embodiment of the present invention, a corrugated dust collector bag is provided.
[0027] Example 1:
[0028] like Figures 1-4 As shown, a corrugated dust collector bag according to an embodiment of the present invention includes a cylindrical bag body 1. A metal support frame 2 is fixedly installed inside the bag body 1 to support the bag body 1, facilitating gas filtration. A positioning frame 3 is fixedly connected to the bottom of the support frame 2. A transmission shaft 4 is rotatably mounted on the surface of the positioning frame 3. One end of the transmission shaft 4 is fixedly connected to a driven fan 5, and the other end is fixedly connected to a transmission frame 6. The driven fan 5 is installed inside the support frame 2, and the transmission frame 6 is installed outside the support frame 2. Three support columns 7 are fixedly connected to the outer surface of the transmission frame 6, and a cleaning roller 8 is rotatably mounted on the surface of each support column 7. When the surface of the bag body 1 needs cleaning after filtering and adsorbing dust in the dust collector, [the cleaning roller 8 is used]. The dust collector generates a pulsed airflow that blows into the interior of the bag body 1 and the support frame 2. The high-speed flow of the pulsed airflow drives the driven fan 5 and the transmission frame 6 to rotate, causing the transmission frame 6 to drive the cleaning roller 8 on the outside of the bag body 1 to rotate continuously, thereby continuously impacting and cleaning the surface of the bag body 1, facilitating the cleaning of the surface of the bag body 1. A reinforcing rod 9 is fixedly connected to one side of the support frame 2, and a high-voltage generator 10 is fixedly installed on the bottom side of the reinforcing rod 9 to provide a sufficiently high voltage power supply to generate the required ionized air. An ion bar 11 is fixedly installed on one side of the high-voltage generator 10. The ion bar 11 continuously blows out an airflow carrying positively charged electrons to neutralize the charge on the surface of the bag body 1, thereby eliminating static electricity on the bag body 1 and effectively suppressing the generation of static electricity on the surface of the bag.
[0029] like Figures 1-4As shown, positioning rings 12 are fixedly connected to both ends of the support frame 2. Clamping rings 13 are provided on the surface of the positioning rings 12. Both the positioning rings 12 and clamping rings 13 have connecting holes 14, which allow the positioning rings 12 and clamping rings 13 to be fixedly connected by bolts. The two ends of the bag body 1 are fixedly clamped between the positioning rings 12 and clamping rings 13, used to fix the bag body 1 onto the outer surface of the support frame 2. The outer surface of the bag body 1 has corrugated pleats 15, used to increase the effective filtration area of the bag body 1 and improve the filtration effect of dust in the air. Both the bag body 1 and the corrugated pleats 15 are made of polyester fiber, which can... The filter bag body 1 and the corrugated pleats 15 are capable of efficient filtration while possessing good mechanical strength and chemical stability. Mounting rods 16 are fixedly connected to both sides of the inner wall of the positioning ring 12, and threaded holes 17 are opened at the ends of the mounting rods 16 for easy fixing of the filter bag body 1 and the support frame 2 inside the dust collector. A grounding wire 18 is rotatably connected to the bottom of the transmission shaft 4. Through the conductivity of the grounding wire 18 and the metal support frame 2, static electricity can be further eliminated from the filter bag body 1. Buffer slopes 19 are opened on both sides of the top of the reinforcing rod 9 to provide wind protection for the ion bar 11 when the pulsed airflow blows inside the support frame 2.
[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0031] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the dust is filtered in the dust collector by the bag body 1 and the wave-shaped pleats 15. When the bag body 1 is working, the ion bar 11 inside continuously blows out airflow with positively charged electrons to neutralize the charge on the surface of the bag body 1, thereby eliminating static electricity on the bag body 1 and effectively suppressing the generation of static electricity on the surface of the bag. This effectively reduces the situation where dust is tightly adsorbed on the bag. When the surface of the bag body 1 needs to be cleaned after adsorbing dust in the dust collector, a pulse airflow is generated in the dust collector and blows into the interior of the bag body 1 and the support frame 2. The high-speed flow of the pulse airflow can drive the driven fan 5 and the transmission frame 6 to rotate, so that the transmission frame 6 drives the cleaning roller 8 on the outside of the bag body 1 to rotate continuously, thereby continuously hitting and cleaning the surface of the bag body 1, causing the dust on the surface of the bag body 1 to fall off quickly, making it easier for the dust to be blown off by the pulse airflow, thereby effectively enhancing the cleaning effect.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
