Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to an anti-wear pleated filter cartridge. Background Art

[0002] Pleated filter cartridges are highly efficient filter components with multiple performance advantages, making them widely used in industrial dust removal. Typically made from long-fiber polyester non-woven fabric and other filter media using advanced pleating technology, these cartridges feature uniform spacing, large interpleat gaps, and wide angles. Their filtration area is 2-5 times larger than that of filter bags of the same diameter and length, and their joints are ultrasonically welded to prevent cracking. Pleated filter cartridges are resistant to acids, alkalis, corrosion, pressure, breakage, moisture, and water, offering high filtration precision and filtration efficiencies up to 99%. They also offer low operating resistance, excellent air permeability, high strength, high tensile strength, and are washable and reusable. Pleated filter cartridges are widely used in industrial dust removal to protect machinery from debris and filter particles from liquids and gases.

[0003] Existing pleated filter cartridges typically allow dust-laden gas to enter the cartridge dust collector, where the dust is intercepted by the filter cloth on the cartridge surface. However, prolonged operation of the dust collector can cause dust erosion and wear on the cartridge. It is important to select wear-resistant filter media and control dust particle size. Excessively high filtration speeds can cause dust to impact the cartridge, resulting in excessive wear. Therefore, the filtration velocity must be adjusted to a reasonable range. Therefore, the wear resistance of pleated filter cartridges is a very important consideration.

[0004] Therefore, we designed an anti-wear pleated filter cartridge to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-wear pleated filter cartridge to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides an anti-wear pleated filter cartridge, including a filter cartridge body, filter material is provided on the outside of the filter cartridge body, and the top and bottom of the filter cartridge body and the filter material are jointly connected with a clamping ring, and a plurality of clamping grooves are opened around the inside of the clamping ring, and an insertion strip is inserted into the inside of each of the clamping grooves, and the top of the insertion strip is against the rear side of the filter material.

[0007] Furthermore, a strap is provided on the outer surface of the filter material, and through grooves are opened around the inside of the strap. A support bar is provided inside each of the through grooves, and the bottoms of the support bars are connected to a connecting block for installing the strap. Since the weight of the strap is very small, the stability of the strap installation can be ensured only by the friction between the top of the support bar and the outer wall of the through groove.

[0008] Furthermore, the top of the support bar abuts against the rear side of the filter material, and the front side of the filter material abuts against the surface of the through groove. The filter material is installed between the support bar and the strap, which further increases the area of ​​the support bar and also ensures the installation of the strap.

[0009] Furthermore, filter holes are provided inside the filter cartridge body. The design of the filter holes helps to reduce the wear of the bottom of the filter cartridge body, and prevents dust from swirling at the bottom of the filter cartridge body and damaging the filter cartridge body.

[0010] Furthermore, a sedimentation area is fixedly provided at the bottom of the bottom clamping ring, and a base is fixedly provided at the bottom of the sedimentation area. The sedimentation area helps to extend the overall service life of the pleated filter cartridge. The sedimentation area allows part of the dust to settle before entering the filter cartridge body, thereby reducing the filtering burden of the filter cartridge body and helping to improve the dust removal efficiency.

[0011] Furthermore, a cavity is provided inside the filter cartridge body and the sedimentation zone.

[0012] Compared with the prior art, the beneficial effect of the present invention is that the top of the insert is abutted against one side of the filter material, so that the other side of the filter material is abutted against the inner wall of the retaining ring, thereby expanding the filter material to the greatest extent, increasing the area of ​​the filter material, and allowing more air to enter the filter cartridge body from the filter material, thereby reducing the wear of the dust on the bottom of the filter cartridge body to a certain extent and improving the durability of the filter cartridge body.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: air is discharged into the interior of the filter cartridge body through the filter holes, the dust-rich air will sink to the bottom of the filter cartridge body, and the dust-free air will float on the upper side, and part of the dust has settled before entering the filter cartridge body, thereby avoiding dust swirling at the bottom of the filter cartridge body and damaging the filter, further reducing the wear of the filter cartridge body by dust, extending the service life, and improving the dust removal efficiency.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-6 The utility model provides a technical solution: an anti-wear pleated filter cartridge, comprising a filter cartridge body 1, a filter material 2 is arranged on the outside of the filter cartridge body 1, and a clamping ring 3 is commonly inserted into the top and bottom of the filter cartridge body 1 and the filter material 2. A plurality of slots 4 are opened around the inside of the clamping ring 3, and an inserting strip 5 is inserted into the inside of each slot 4, and the top of the inserting strip 5 is against the rear side of the filter material 2, and a binding band 6 is provided on the outer surface of the filter material 2. A through groove 7 is opened around the inside of the binding band 6, and a support bar 8 is provided inside each through groove 7. The bottom of the support bar 8 is commonly connected to a connecting block 9, and the top of the support bar 8 is against the rear side of the filter material 2, and the front side of the filter material 2 is against the surface of the through groove 7. The interior of the filter cartridge body 1 is provided with a filter hole 10.

[0023] In specific implementation, when installing the device, first splice the filter cartridge body 1 and the filter material 2 together, then clamp the clamping ring 3 on the top and bottom of the filter cartridge body 1 and the filter material 2, and then insert each insertion strip 5 into the clamping groove 4 opened in the clamping ring 3, and make the top of the insertion strip 5 abut against one side of the filter material 2, and make the other side of the filter material 2 abut against the inner wall of the clamping ring 3, so as to expand the filter material 2 to the greatest extent, increase the area of ​​the filter material 2, and allow more air to enter the filter cartridge body 1 from the filter material 2, thereby reducing the wear of the bottom of the filter cartridge body 1 by dust to a certain extent and improving the durability of the filter cartridge body 1.

[0024] Before installing the snap ring 3, first install the strap 6 in the corresponding position so that the top of the support bar 8 is tightly against the rear side of the filter material 2, and the front side of the filter material 2 is tightly against the surface of the through groove 7. Since the weight of the strap 6 is very small, the stability of the installation of the strap 6 can be ensured only by the friction between the top of the support bar 8 and the outer wall of the through groove 7.

[0025] See Figure 1-6As shown, a sedimentation area 11 is fixedly provided at the bottom of the bottom clamping ring 3 , a base 12 is fixedly provided at the bottom of the sedimentation area 11 , and cavities are provided inside the filter cartridge body 1 and the sedimentation area 11 .

[0026] In specific implementation, when air enters the interior of the filter cartridge body 1 through the filter hole 10, the dust-rich air will sink to the bottom of the filter cartridge body 1, while the dust-free air will float on the upper side, and some dust will settle before entering the filter cartridge body 1, thereby avoiding dust swirling at the bottom of the filter cartridge body 1 and damaging the filter, further reducing the wear of the filter cartridge body 1 by dust, extending the service life, and improving the dust removal efficiency.

[0027] Filter media 2 is typically made of long-fiber polyester non-woven fabric, manufactured using advanced pleating technology. This material features uniform spacing, large interpleat spaces, and a wide angle. Its filtration area is 2-5 times greater than that of a filter bag of the same diameter and length. Ultrasonic welding is used to prevent cracking in the joints. Furthermore, this filter material is resistant to acids, alkalis, corrosion, pressure, breakage, moisture, and water, offering high filtration precision and filtration efficiencies up to 99%. It also offers low operating resistance, high air permeability, high strength, and high tensile strength, making it washable and reusable.

[0028] In addition, the design of the settling area 11 is mainly to reduce the wear of the filter cartridge body 1, extend the service life, and improve the dust removal efficiency. When heavier and more abrasive dust falls directly into the ash hopper, the dust is prevented from swirling at the bottom of the filter cartridge body 1 and damaging the filter cartridge body 1. By reducing the wear of the bottom of the filter cartridge body 1, the settling area 11 helps to extend the overall service life of the pleated filter cartridge. The settling area 11 allows some dust to settle before entering the filter cartridge body 1, thereby reducing the filtration burden of the filter cartridge body 1 and helping to improve the dust removal efficiency.

[0029] In addition, the design of the filter holes 10 can increase the effective filtration area of ​​the filter cartridge body 1, so that more dust-laden gases can be filtered through the filter holes 10, thereby improving the filtration efficiency. By reasonably designing the filter holes 10, the average pressure difference of the dust collector during operation can be reduced, thereby reducing energy consumption and reducing the pulse cleaning frequency required for the filter element, further reducing energy consumption. The design of the filter holes 10 helps to reduce the wear on the bottom of the filter cartridge body 1 by allowing heavier and more abrasive dust to fall directly into the ash hopper, thereby avoiding dust swirling at the bottom of the filter cartridge body 1 and damaging the filter cartridge body 1. The design of the filter holes 10 should be based on the pressure loss, filtration efficiency, economy and cleaning performance analysis of the filter cartridge body 1 to determine the structural parameters of the filter cartridge body 1, including the distribution and size of the filter holes 10, and increase the effective filtration area through folding processing while maintaining a low operating resistance to improve cleaning efficiency.

[0030] Working principle: When installing the device, first splice the filter cartridge body 1 and the filter material 2 together, then clamp the clamping ring 3 to the top and bottom of the filter cartridge body 1 and the filter material 2, and then insert each insertion strip 5 into the clamping groove 4 opened in the clamping ring 3, and make the top of the insertion strip 5 abut against one side of the filter material 2, and make the other side of the filter material 2 abut against the inner wall of the clamping ring 3, so as to expand the filter material 2 to the greatest extent, increase the area of ​​the filter material 2, and allow more air to enter the filter cartridge body 1 from the filter material 2, thereby reducing the wear of the bottom of the filter cartridge body 1 by dust to a certain extent and improving the durability of the filter cartridge body 1.

[0031] Before installing the snap ring 3, first install the strap 6 in the corresponding position so that the top of the support bar 8 is tightly against the rear side of the filter material 2, and the front side of the filter material 2 is tightly against the surface of the through groove 7. Since the weight of the strap 6 is very small, the stability of the installation of the strap 6 can be ensured only by the friction between the top of the support bar 8 and the outer wall of the through groove 7.

[0032] When air enters the interior of the filter cartridge body 1 through the filter hole 10, the dust-rich air will sink to the bottom of the filter cartridge body 1, while the dust-free air will float on the upper side, and some dust will settle before entering the filter cartridge body 1, thereby avoiding dust swirling at the bottom of the filter cartridge body 1 and damaging the filter, further reducing the wear of the filter cartridge body 1 by dust, extending its service life, and improving the dust removal efficiency.
