Abstract
The utility model discloses end plate outer ring part for a kind of hammer mill, it is characterized in that: end plate outer ring part is assembled by each covering of the fan part, each covering of the fan part is along the assembled full circle ring that is of circumference of disintegrating machine end plate; On covering of the fan part, be provided with arc step surface; edge with arc step surface and disintegrating machine end plate closely cooperates; form the edge-protected plate of end plate; internal ring portion position at each covering of the fan part is provided with installing hole; use for bolted; the outer shroud position of each covering of the fan part is set to tapered end face, forms guide face with tapered end face.The utility model is not affecting under the prerequisite of rotor general assembly and crushing effect, forms the effective protection to rotor end plate, to improving the service life of disintegrating machine end plate.
Description
Technical field
The utility model is end plate outer ring part for a kind of hammer mill, for the protection of disintegrating machine end plate, improves end plate service life.Reducing material enters in the crack between rotor end plate and disintegrating machine side casing.
Background technology
Hammer mill in the course of the work, impacts and friction owing to being subject to the brute force of material, inevitably forms impact, wearing and tearing to main strike part rotor block.And end plate is the important component part of rotor structure, its design rationally whether will directly affect its life-span, thereby affect the life-span of rotor block.Hammer mill in the market mainly adopts traditional monomer end plate design, in the time of broken material, some undersized material pieces are easy to enter the gap between rotor side hammer head lateral surface and disintegrating machine side housing, thereby form impact and wearing and tearing to end plate column face and two end face edge regions, conventionally rotor monomer end plate takes the mode of edge build-up wear-resistant material to be protected, if but it in use fails timely repair welding high-abrasive material, will cause whole end plate premature failure.
Utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art; end plate outer ring part for a kind of hammer mill is provided; do not affecting under the prerequisite of rotor general assembly and crushing effect, forming the effective protection to rotor end plate, to improving the service life of disintegrating machine end plate.
The utility model is that technical solution problem adopts following technical scheme:
The utility model hammer mill by the design feature of end plate outer ring part is: described end plate outer ring part is assembled by each covering of the fan part, and described each covering of the fan part is along the assembled full circle ring that is of circumference of disintegrating machine end plate; On described covering of the fan part, be provided with arc step surface; edge with described arc step surface and disintegrating machine end plate closely cooperates; form the edge-protected plate of end plate; internal ring portion position at described each covering of the fan part is provided with installing hole; use for bolted; the outer shroud position of described each covering of the fan part is set to tapered end face, forms guide face with described tapered end face.
The utility model hammer mill is also by the design feature of end plate outer ring part:
Described end plate outer ring part is to be fixedly connected with disintegrating machine end plate by installing hole by bolt.
Described each covering of the fan part is by high hardness wear-resisting material monolithic casting.
Described high hardness wear-resisting material refers to that HRC value is not less than 45 high-abrasive material.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model matches with housing back-up ring liner plate, forms the conical surface folder gap that material conductance draws, and can effectively prevent that material from entering the gap between rotor and housing, can reduce the wearing and tearing to end plate sidewall and body inwall;
2, the utility model adopts the casting of high hardness wear-resisting material to form, and antiwear property is strong, and it means to end plate outer rim and puts on thick armoring coat, effectively protects end plate outer rim not worn and torn by material;
3, simple in structure, reliable, the processing and manufacturing of the utility model and change convenient, service efficiency is high, cost is low, its removable installation form can be changed separately it, has effectively protected element of installation.

Detailed description of the invention
Referring to Fig. 1, Fig. 2 a, Fig. 2 b and Fig. 2 c, in the present embodiment, hammer mill by the version of end plate outer ring part is: end plate outer ring part 3 is assembled by each covering of the fan part, and each covering of the fan part is along the assembled full circle ring that is of circumference of disintegrating machine end plate 5; On described covering of the fan part, be provided with arc step surface 3a; edge with described arc step surface 3a and disintegrating machine end plate 5 closely cooperates; form the edge-protected plate of end plate; internal ring portion position at described each covering of the fan part is provided with installing hole 3b; use for bolted; the outer shroud position of described each covering of the fan part is set to tapered end face 3c, forms guide face with described tapered end face 3c.
In concrete enforcement, end plate outer ring part 3 is to be fixedly connected with disintegrating machine end plate 5 by installing hole 3b by bolt; In order to improve antiwear property, each covering of the fan part is by high hardness wear-resisting material monolithic casting, and high hardness wear-resisting material refers to that HRC value is not less than 45 high-abrasive material.
End plate outer ring part in the present embodiment position easy to wear is implemented effectively protection to disintegrating machine end plate at its edge, and is combined into complex with disintegrating machine end plate, and can change, and has effectively protected element of installation.
For existing version, in the time of crusher in crushing material, the piece material that a part is broken can be diverted to the two ends of rotor block, i.e. gap location between side hammer head 4 and side casing 2, will inevitably cause the outer peripheral of disintegrating machine end plate 5 washed away and worn and torn; The version providing in the present embodiment is protected the outward flange of disintegrating machine end plate 5 with end plate outer ring part 3 on the one hand; On the other hand, the outer shroud position tapered end face 3c of end plate outer ring part 3 matches with the conical surface that is arranged on the housing back-up ring liner plate 1 on side casing 2, forms the guide function to material flow, further stops material to enter gap, thereby significantly reduces wearing and tearing.
