[0003] When the dust removal filter cartridge filters dust, it filters through the filter paper outside the supporting inner net. The filter paper forms pleated strips to increase the filtering area. Although the pleated structure increases the filtering area, dust is likely to accumulate in the pleated gaps during the filtering process. When the filter cartridge is cleaned, the dust accumulated in the pleated gaps is not easy to clean, resulting in a reduction in the filtering efficiency of the filter cartridge. Summary of the Utility Model
[0004] The purpose of the utility model is to propose an industrial dust removal filter cartridge to solve the problem that dust is likely to accumulate in the pleated gaps of the existing dust removal filter cartridge, resulting in a reduction in the filtering effect of the dust removal filter cartridge.
[0005] To achieve the above purpose, the utility model adopts the following technology: an industrial dust removal filter cartridge, including a supporting inner net, a filter paper is sleeved outside the supporting inner net, and pleated strips are formed on the filter paper along the axial direction of the supporting inner net. The bottom and top of the supporting inner net are respectively detachably connected with a lower end cover and an upper end cover. A threaded end is integrally formed on the top of the upper end cover. A dust cleaning component for blowing air along the length direction of the pleated strip is arranged on the upper end cover, and a reinforcement component is arranged on the lower end cover.
[0006] As a further description of the above technical solution: the dust cleaning component includes a fixed pipe arranged on the top of the upper end cover. A connecting end is arranged on the fixed pipe and is communicated with the fixed pipe. A blowing nozzle penetrating the upper end cover is arranged at the bottom of the fixed pipe.
[0007] As a further description of the above technical solution: the number of the blowing nozzles is several and they are all communicated with the fixed pipe. The blowing nozzles are arranged along the axial direction of the supporting inner net, and the blowing nozzles and the pleated strips are distributed in a staggered manner.
[0008] As a further description of the above technical solution: a limiting block abutted against the top of the fixed pipe is arranged on the upper end cover through an installation groove. A spring is arranged between the limiting block and the inner wall of the installation groove.
[0009] As a further description of the above technical solution: a gasket is provided at the bottom of the limit block through a card slot.
[0010] As a further description of the above technical solution: the reinforcement component includes a fixing column arranged between two adjacent pleated strips, an elastic sheet is arranged on the fixing column, and a baffle plate in contact with the pleated strip is arranged at one end of the elastic sheet.
[0011] As a further description of the above technical solution: a connecting screw rod penetrating through the lower end cover is arranged at the bottom of the fixing column, and a locking nut abutted against the bottom of the lower end cover is arranged on the connecting screw rod.
[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.
[0024] Referring to Figures 1-6 , an industrial dust removal filter cartridge provided in this embodiment includes a support inner network 1. A filter paper 2 is sleeved outside the support inner network 1, and pleat strips 3 are formed on the filter paper 2 along the axial direction of the support inner network 1. The bottom and top of the support inner network 1 are detachably connected with a lower end cover 4 and an upper end cover 5 respectively. A threaded end 6 integrally formed with the upper end cover 5 is provided at the top of the upper end cover 5. A dust cleaning component 7 for blowing air along the length direction of the pleat strips 3 is provided on the upper end cover 5, and a reinforcement component 8 is provided on the lower end cover 4.
[0025] In the present invention, the filter cartridge is installed on the dust collector through the threaded end 6 of the upper end cover 5. During the dust removal work, the dust-containing gas enters the dust collector and contacts the filter cartridge. The filter paper 2 on the support inner network 1 filters the dust in the gas. The filter paper 2 adopts a design with pleat strips 3, which can greatly increase the contact area with the gas, thereby effectively filtering the dust in the gas. The filtered gas is discharged from the through hole of the upper end cover 5. When the dust on the filter paper 2 needs to be cleaned, the dust cleaning component 7 can blow air to the filter paper 2, and the blowing direction is along the gap between the pleat strips 3, which can effectively clean the dust accumulated between the pleat strips 3. During the blowing dust cleaning process, the reinforcement component 8 can reinforce the pleat strips 3, avoid the pleat strips 3 from having too large a deflection amplitude, and thus effectively avoid the deformation of the pleat strips 3, ensuring that the filter paper 2 can achieve an efficient filtering effect.
[0026] Specifically, as Figure 1 and Figure 3As shown in the figure, the dust cleaning assembly 7 includes a fixed pipe 71 provided on the top of the upper end cover 5. A connection end 72 communicating with the fixed pipe 71 is provided on the fixed pipe 71. A blowing nozzle 73 penetrating the upper end cover 5 is provided at the bottom of the fixed pipe 71. The number of the blowing nozzles 73 is several and they are all communicated with the fixed pipe 71. The blowing nozzles 73 are arranged along the axial direction of the support inner net 1, and the blowing nozzles 73 and the corrugated strips 3 are distributed in a staggered manner.
[0027] Among them, the blowing nozzles 73 at the bottom of the fixed pipe 71 are arranged in a staggered manner between two adjacent corrugated strips 3. When dust cleaning is required, the connection end 72 on the fixed pipe 71 is connected to an air pump. The air pump sprays compressed air through the blowing nozzles 73, and the sprayed air flow blows down the dust accumulated between the corrugated strips 3, thus preventing dust from adhering between the corrugated strips 3, which is beneficial to the peeling and falling of the dust on the filter cartridge, and preventing the reduction of the dust removal efficiency of the filter cartridge due to the dust in the corrugated gaps of the filter cartridge.
[0028] Specifically, as Figure 1 、 Figure 4 and Figure 5 shown, a limiting block 52 abutted against the top of the fixed pipe 71 is provided on the upper end cover 5 through an installation groove 51. A spring 53 is provided between the limiting block 52 and the inner wall of the installation groove 51.
[0029] Among them, an orifice matching the blowing nozzle 73 is opened on the upper end cover 5. When the dust cleaning assembly 7 is installed, the fixed pipe 71 is sleeved outside the threaded end 6 of the upper end cover 5, and the blowing nozzles 73 on the fixed pipe 71 are aligned with the orifice position of the upper end cover 5. During the process of pressing down the fixed pipe 71, the fixed pipe 71 squeezes the limiting block 52, causing the limiting block 52 to compress the spring 53 and then contract in the installation groove 51 until the fixed pipe 71 abuts against the top of the upper end cover 5. At this time, the limiting block 52 pops out under the action of the spring 53 and abuts against the top of the fixed pipe 71, thereby cooperating with the orifice to limit the fixed pipe 71 and ensuring the stability of the dust cleaning assembly 7 on the filter cartridge;
[0030] It should be noted that a gasket 522 is provided at the bottom of the limiting block 52 through a card slot 521. The gasket 522 is made of rubber material. When the fixed pipe 71 is installed, the limiting block 52 abuts against the top of the fixed pipe 71. At this time, the gasket 522 contacts the fixed pipe 71. The rubber gasket 522 can prevent the limiting block 52 from damaging the fixed pipe 71 and improve the safety after the installation of the dust cleaning assembly 7.
[0031] Specifically, as Figure 1 and Figure 6As shown, the reinforcement component 8 includes a fixing post 81 arranged between two adjacent pleated strips 3. An elastic piece 82 is arranged on the fixing post 81, and a baffle 83 in contact with the pleated strip 3 is arranged at one end of the elastic piece 82. A connecting screw 84 penetrating the lower end cover 4 is arranged at the bottom of the fixing post 81, and a locking nut 85 abutted against the bottom of the lower end cover 4 is arranged on the connecting screw 84.
[0032] Among them, the fixing post 81 can be conveniently disassembled and assembled on the lower end cover 4 through the connecting screw 84 and the locking nut 85. The baffle 83 is arranged on the fixing post 81 through the elastic pieces 82 arranged in an inverted V shape. When the dust cleaning component 7 blows air to clean the dust, the elastic pieces 82 on the adjacent fixing posts 81 cooperate with the baffle 83 to clamp the pleated strip 3, avoid the shaking and deformation of the pleated strip 3, and ensure that the filter paper 2 can achieve an efficient filtering effect.
[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
