Abstract
The utility model discloses a kind of cutter shaft of refuse grinder, comprise axis body and blade, blade is fixedly connected with axis body, it is characterized in that described blade is made up of tool bit part, knife edge part and body portion, blade is uniformly distributed along the axial screw of axis body, each blade all has tool bit part, knife edge part, the body portion of two corresponding distributions, and adjacent knife blades angle is vertically between 15 ~ 40 degree.Knife edge part described in the utility model is U-shaped.Axis body material described in the utility model is high strength alloy steel, and described blade material is high abrasion resisting material.The utility model has simple for structure, and installation and debugging are convenient, the large reliability high of moment of torsion, and cutter shaft peak torque can bear 80kNm, evenly broken, can realize the coarse crushing to rubbish.
Description
Technical field
The utility model relates to the cutter shaft of the refuse grinder of coarse crushing before a kind of waste incineration and generating electricity.
Background technology
Current process house refuse adopts land-fill method mostly, long-term land occupation resource contaminated environment again, now progressively adopts waste incineration and generating electricity to process house refuse.Broken pretreatment must be carried out to rubbish and just can obtain higher calorific value before burning electricity generation, reduce environmental pollution.Refuse grinder developed very fast in the last few years abroad, domestic mainly dependence on import equipment.During refuse grinder work, carry out fragmentation by low-speed big cutter shaft, therefore tool setting shaft portion requires to bear high pulling torque.
The cutter shaft of existing disintegrating machine does not generally reach high pulling torque requirement, and blade abrasion is fast and broken Bulky Waste effect is undesirable, is suitable for the fine crushing sorting rear rubbish.Such as publication number patent application document " crusher in crushing cutter " disclosed in CN 103447133 A is suitable for the fine crushing of rubbish, is not suitable for the coarse crushing of Bulky Waste.
Utility model content
The utility model, in order to overcome the defect of above-mentioned prior art, devises a kind of simple for structure convenient and practical, is applicable to the cutter shaft of the refuse grinder of garbage rough fragmentation.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of cutter shaft of refuse grinder, mainly comprise axis body and blade, it is characterized in that described blade is made up of tool bit part, knife edge part and body portion, blade is uniformly distributed along the axial screw of axis body, each blade all has tool bit part, knife edge part, the body portion of two corresponding distributions, and adjacent knife blades angle is vertically between 15 ~ 40 degree.The utility model structure is simple, and the gap ratio between cutter tooth and fixed blade is comparatively large, is conducive to big article that cutter tooth is promptly broken and applies moment, tear and extrude in time, realize broken great efforts to the broken thing of size, and evenly broken.
Knife edge part described in the utility model is U-shaped.Owing to not having outstanding cutter tooth, can hold larger object, by interacting with fixed blade, the comprehensive effect tear broken thing, shear, extruded realizes and ensures the optimization to broken material fragmentation.
Axis body material described in the utility model is high strength alloy steel, and described blade material is high abrasion resisting material.
The cutter shaft of the utility model refuse grinder has simple for structure, and installation and debugging are convenient, the large reliability high of moment of torsion.Cutter shaft peak torque can bear 80kNm, evenly broken, can realize the coarse crushing to rubbish.

Fig. 2 is the structural representation of the utility model embodiment blade.
Detailed description of the invention
See Fig. 1, Fig. 2, the cutter shaft of the utility model embodiment refuse grinder comprise axis body 1 and on axis body 1 vertically with some blades 2 that certain angle (being generally 15 ~ 40 degree) spiral is uniform, blade 2 comprises tool bit part 3, knife edge part 4 and cutter blade part 5.The quantity of blade 2 is preferably 8 ~ 20.Wherein each blade 2 all has tool bit part 3, knife edge part 4 and the cutter blade part 5 of two corresponding distributions (symmetrical, shaft section becomes 180 degree of distributions), as shown in Figure 2.Such structure makes cutter head only have two symmetrical cutters tooth (the sharp-pointed portion of tool bit part 3) in certain direction, these two gap ratios between cutter tooth and fixed blade are larger, be conducive to big article that cutter tooth is promptly broken and apply moment, can in time the broken thing of size be torn and be extruded, and knife edge part 4 is U-shaped, owing to there is no outstanding cutter tooth, larger object can be held, by interacting with fixed blade, broken thing is sheared and extruded, by tearing, shear, the comprehensive effect of extruding realizes and ensures the optimization to broken material fragmentation.The structure of blade 2 is symmetrical, effectively can carry out fragmentation to broken thing like this when cutter shaft rotates and reverse.
Axis body 1 material is high strength alloy steel.Blade 2 is high abrasion resisting material.Be Welding Structure between blade 2 and axis body 1, structure is simple.Blade 2 upon wear, can carry out repair welding and continue to use.
The present embodiment blade 2 is uniform with certain helical along the axis of axis body 1, each moment can be kept like this to have blade 2 carrying out fragmentation when cutter shaft rotates, adding cutter shaft is low-speed big, cutter shaft peak torque can bear 80kNm, therefore this cutter shaft structure is well suited for the coarse crushing of rubbish, broken great efforts and broken evenly.
The equivalent transformation of every technical solutions of the utility model and technical characteristic or combination, all should think and fall into protection domain of the present utility model.
