Description

Technical Field

[0001] This utility model relates to the field of waste residue treatment technology, and in particular to a crushing device for waste residue treatment. Background Technology

[0002] Metallurgical slag is a waste or byproduct generated during the metallurgical process, typically including metal residues, slag, and furnace slag. These slags may contain useful metal components, thus requiring treatment and recycling. Before recycling, they need to be crushed. Currently, the equipment used for crushing slag is mostly pulverizers or crushers. However, these devices have simple structures and functions, only performing single-function crushing, resulting in less than ideal treatment efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a crushing device for waste residue treatment in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A pulverizing device for waste residue treatment includes a support mechanism, which includes a support box. A processing cylinder is vertically fixed at the upper end of the support box. A frame fixedly connected to the support box is provided on the outside of the processing cylinder. A conical feeding hopper is provided at the upper end of the processing cylinder. A discharge hopper is connected to the lower part of the processing cylinder. A pulverizing mechanism for crushing and grinding the added waste residue is provided inside the support mechanism. The pulverizing mechanism includes a pulverizing component. A power component is connected to the lower end of the pulverizing component. The pulverizing component includes a central shaft vertically arranged inside the processing cylinder. A grinding roller is fixed on the central shaft at the lower part of the processing cylinder. A grinding sleeve corresponding to the grinding roller is installed on the inner wall of the processing cylinder. A pulverizing blade and a spiral blade are arranged sequentially upwards on the outer diameter of the central shaft above the grinding roller.

[0006] Further configuration: The central shaft is rotatably connected to the processing cylinder and the support box, and a flange supporting the grinding sleeve is provided on the inner wall of the processing cylinder.

[0008] Further configuration: The shredder blades are circumferentially distributed radially on the central axis, and staggered axially on the central axis.

[0009] Further configuration: The spiral blades are welded to the central shaft, and the spiral blades are fitted to the inner wall of the processing cylinder.

[0010] Further configuration: The inner bottom of the processing cylinder slopes downward toward the discharge hopper.

[0011] Further configuration: The power assembly includes an electric motor installed in the support box, a main gear installed at the output end of the electric motor, and a transmission gear meshing with the main gear fixed on the central shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The crushing mechanism on the support structure drives the grinding roller, crushing blades, and spiral blades on the central shaft to rotate. The waste residue is fed into the hopper on the processing cylinder and conveyed downwards by the rotating spiral blades. After being initially crushed by the rotating interlaced crushing blades, it falls downwards between the grinding sleeve and the grinding roller. The rotating grinding roller then further grinds the waste residue, resulting in multiple crushing processes that improve the waste residue treatment efficiency. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-4 As shown, a waste residue crushing device includes a support mechanism, which includes a support box 11. A processing cylinder 13 is vertically fixed to the upper end of the support box 11. A frame 12, which is fixedly connected to the support box 11, is provided on the outside of the processing cylinder 13 to provide fixed support for the processing cylinder 13. A conical feeding hopper 14 is provided at the upper end of the processing cylinder 13. A discharge hopper 15 is connected to the lower part of the processing cylinder 13. The bottom inner side of the processing cylinder 13 slopes downward toward the discharge hopper 15. A crushing mechanism for crushing and grinding the added waste residue is provided inside the support mechanism.

[0025] In this embodiment: the crushing mechanism includes a crushing component, the lower end of which is connected to a power component. The crushing component includes a central shaft 21 vertically disposed inside the processing cylinder 13. A grinding roller 22 is fixed on the central shaft 21 at a lower position in the processing cylinder 13. A grinding sleeve 23 corresponding to the grinding roller 22 is installed on the inner wall of the processing cylinder 13. Crushing blades 24 and spiral blades 25 are sequentially arranged on the outer diameter of the central shaft 21 above the grinding roller 22. The central shaft 21 is rotatably connected to the processing cylinder 13 and the support box 11. A flange supporting the grinding sleeve 23 is provided on the inner wall of the processing cylinder 13. The upper end of the grinding roller 22 is conical, and the upper end of the grinding sleeve 23 is inverted conical, guiding the waste residue after crushing by the crushing blades 24 to flow. Waste residue is fed between grinding roller 22 and grinding sleeve 23. Grinding ribs are provided on the opposing surfaces of grinding roller 22 and grinding sleeve 23. Crushing blades 24 are circumferentially distributed radially on the central shaft 21 and staggered axially on the central shaft 21. Spiral blades 25 are welded to the central shaft 21 and adhere to the inner wall of the processing cylinder 13. The grinding roller 22, crushing blades 24 and spiral blades 25 on the central shaft 21 are rotated by the power assembly, so that the added waste residue is conveyed downward through the rotating spiral blades 25. After being initially crushed by the rotating staggered crushing blades 24, it falls downward between the grinding sleeve 23 and grinding roller 22, and is further ground by the rotating grinding roller 22.

[0026] The power assembly includes an electric motor 27 installed in the support box 11. A main gear 28 is installed at the output end of the electric motor 27. A transmission gear 26 that meshes with the main gear 28 is fixed on the central shaft 21. The operation of the electric motor 27 drives the main gear 28 to mesh and rotate with the transmission gear 26, so that the transmission gear 26 drives the central shaft 21 to rotate as a whole.

[0027] The working principle and usage process of this utility model are as follows: The motor 27 drives the main gear 28 to mesh and rotate with the transmission gear 26, which in turn drives the grinding roller 22, crushing blade 24 and spiral blade 25 on the central shaft 21 to rotate. The waste residue is added into the feeding hopper 14 at the upper end of the processing cylinder 13. The rotating spiral blade 25 conveys the waste residue downward. The waste residue is initially crushed by the rotating interlaced crushing blade 24 and then falls downward between the grinding sleeve 23 and the grinding roller 22. The rotating grinding roller 22 further grinds the waste residue, which then falls down and is discharged through the discharge hopper 15.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
