[0024] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0025] Combination Figure 1-Figure 5 The utility model discloses a dust removal device for a material pneumatic conveying pipeline, comprising a dust removal cylinder 1, both ends of which are provided with flanges 11, through which the dust removal cylinder 1 can be fixed to the material pneumatic conveying pipeline, and one end of which is provided with a conical air collecting plate 2 and connected to the material inlet end.

[0026] A conical air collecting plate 2 is provided at one end of the impurity removal cylinder 1, and an air outlet 22 is opened at one end of the conical air collecting plate 2 close to the mounting box 31. The materials passing through the conical air collecting plate 2 are discharged from the air outlet 22 in a concentrated manner. All the materials hit the conveyor belt 34 and are discharged from the upper and lower sides of the conveyor belt 34, thereby improving the adsorption effect.

[0027] One side of the conical air collecting plate 2 is fixedly connected with an impurity removal component 3 through a support frame 21. The impurity removal component 3 includes an installation box 31, a magnet tube 32, a transmission roller 33, a conveyor belt 34 and a driving motor 35. The driving motor 35 controls the rotation of the transmission roller 33. The magnet tube 32 and the transmission roller 33 form a quadrilateral structure, and the magnet tube 32 and the transmission roller 33 are jointly sleeved with a conveyor belt 34. The end of the conveyor belt 34 close to the conical air collecting plate 2 is a transversely arranged V-shaped structure to reduce the resistance to the material. The part of the conveyor belt 34 that contacts the magnet tube 32 is placed outside the installation box 31. The conveyor belt 34 that contacts the magnet tube 32 has a certain adsorption force, which adsorbs impurities in the material and drives the impurities to move under the transmission of the conveyor belt 34.

[0028] A center frame 311 is disposed inside the installation box 31 . The support frame 21 penetrates the center frame 311 and is connected to the outer wall of the conical wind collecting plate 2 . The position of the installation box 31 is fixed by the support frame 21 .

[0029] The center frame 311 is connected to a magnet plate 36, and the magnet plate 36 is placed between the magnet tubes 32. After the magnet tube 32 is sleeved with the conveyor belt 34, the magnet plate 36 supports the conveyor belt 34, while ensuring that the conveyor belt 34 exposed outside the installation box 31 has adsorption force, and a half magnet plate 36 is provided on one side of the magnet plate 36 close to the bottom, which is used to extend the adsorption length of the conveyor belt 34, so that the conveyor belt 34 without adsorption force is placed in the installation box 31.

[0030] The driving motor 35 is installed on the center frame 311, and the output end of the driving motor 35 is fixedly connected to the first gear 351, and one end of the transmission roller 33 is fixedly connected to the second gear 331, and the second gear 331 is meshed with the first gear 351. When the driving motor 35 is working, it drives the first gear 351 connected thereto to drive the second gear 331 to rotate, and the second gear 331 controls the transmission roller 33 to rotate, and the conveyor belt 34 on the transmission roller 33 is displaced.

[0031] The inner wall of the transmission belt 34 close to the second gear 331 is provided with teeth 341 meshing with the second gear 331 . With the support of the teeth 341 , the reliability of the transmission belt 34 can be improved.

[0032] A sealing plate 312 is provided at the upper end of the installation box 31 to prevent materials from falling into the installation box 31. The installation box 31 is placed below the transmission roller 33 and a receiving plate 313 is provided. After the conveyor belt 34 moves into the installation box 31 with the adsorbed impurities, it is gradually removed from the magnet plate 36. Without the adsorption effect of the magnet plate 36 and the magnet cylinder 32, the impurities are collected in the installation box 31, and the conveyor belt 34 with the impurities removed is moved out from the upper end of the installation box 31 again to re-adsorb the impurities.

[0033] Working process: fix the impurity removal cylinder 1 to the material wind conveying pipeline through the flange 11, the material enters the impurity removal cylinder 1 from one end of the conical air collecting plate 2, and the material passing through the conical air collecting plate 2 is discharged from the air outlet 22, all the materials hit the conveyor belt 34, the magnet plate 36 and the magnet cylinder 32 adsorb the impurities in the material, and the material is discharged from the upper and lower sides of the conveyor belt 34 under the action of wind, and the driving motor 35 works, through the first gear 351 and the second gear 331, to drive the transmission roller 33 to rotate, control the displacement of the conveyor belt 34, and the conveyor belt 34 moves along the magnet plate 36 and the magnet cylinder 32. Impurities are always adsorbed on the surface of the conveyor belt 34. When the conveyor belt 34 adsorbed with impurities enters the installation box 31 from the bottom of the installation box 31, the conveyor belt 34 is separated from the magnet plate 36 and the magnet cylinder 32, and the impurities lose their adsorption force and fall into the installation box 31 for collection. The cleaned conveyor belt 34 moves to the outside of the installation box 31 again for impurity adsorption.

[0034] To sum up: the utility model is a kind of impurity removal device for material pneumatic conveying pipeline, which is installed on the material pneumatic conveying pipeline through the impurity removal cylinder 1, and uses the conical air collecting plate 2 to change the moving path of the material so that it is gathered on the surface of the conveyor belt 34 to improve the adsorption cleanliness of the material, and under the action of the magnet cylinder 32 and the magnet plate 36, the impurities are adsorbed to the surface of the conveyor belt 34, and the conveyor belt 34 is driven to move by the transmission roller 33, and the adsorbed impurities are cleaned in time to ensure that the conveyor belt 34 can be adsorbed for a long time.
