Abstract
The invention discloses an end disc outer ring piece for a hammer crusher. The end disc outer ring piece for the hammer crusher is characterized in that the end disc outer ring piece is formed by splicing sector pieces, wherein sector pieces are spliced into a whole circular ring along the circumference of a crusher end disc; an arc-shaped stepped surface is formed in the sector piece and is in close fit with an edge of the crusher end disc so as to form an end disc edge protection plate; a mounting hole is formed in an inner ring part of each sector piece for fastening a bolt; a conical end face is formed in an outer ring part of each sector piece; and a guide surface is formed by virtue of the conical end face. According to the end disc outer ring piece for the hammer crusher disclosed by the invention, a rotor end disc is effectively protected under the condition that the rotor general assembly and crushing effect is not influenced, so that the service life of the crusher end disc is expected to be prolonged.
Description
Technical field
The present invention is the outer collar member of a kind of hammer mill end plate, for the protection of disintegrating machine end plate, improves end plate service life.Reduce material to enter in the crack between rotor end plate and disintegrating machine side casing.
Background technology
Hammer mill in the course of the work, owing to being subject to brute force attack and the friction of material, is inevitably formed main impact, the wearing and tearing of hitting part rotor block.And end plate is the important component part of rotor structure, the whether reasonable of its design will directly affect its life-span, thus affect the life-span of rotor block.Hammer mill in the market mainly adopts traditional monomer end plate design, when broken material, some undersized material blocks are easy to enter the gap between rotor side hammer head lateral surface and disintegrating machine side housing, thus the impact formed end plate column face and two end face edge regions and wearing and tearing, usual 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.
Summary of the invention
The present invention is the weak point for avoiding existing for above-mentioned prior art; there is provided a kind of hammer mill end plate outer collar member; under the prerequisite not affecting rotor general assembly and crushing effect, form the available protecting to rotor end plate, to improving the service life of disintegrating machine end plate.
The present invention is that technical solution problem adopts following technical scheme:
The design feature of the outer collar member of hammer mill end plate of the present invention is: the outer collar member of described end plate is assembled by each covering of the fan part, and described each covering of the fan part is assembled in full circle ring along the circumference of disintegrating machine end plate; Described covering of the fan part is provided with arc-shaped step face; coordinate with the edges close of disintegrating machine end plate with described arc-shaped step face; form end plate edge protection plate; installing hole is provided with at the inner ring position of described each covering of the fan part; 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 design feature of the outer collar member of hammer mill end plate of the present invention is also:
The outer collar member of described end plate is 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 the high-abrasive material of 45.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention matches with housing back-up ring liner plate, forms the conical surface folder gap of stream guiding, effectively can prevent material from entering gap between rotor and housing, can reduce the wearing and tearing to end plate sidewall and body inwall;
2, the present invention adopts high hardness wear-resisting cast to form, and antiwear property is strong, and it means puts on thick armoring coat to end plate outer rim, and effective protection end plate outer rim is not worn and torn by material;
3, simple, reliable, the processing and manufacturing of structure of the present invention and change convenient, service efficiency is high, cost is low, its removable installation form makes it change separately, available protecting element of installation.

Number in the figure: 1 housing back-up ring liner plate, 2 side casings, the outer collar member of 3 end plates, 3a arc-shaped step face, 3b installing hole, 3c tapered end face, 4 side hammer heads, 5 disintegrating machine end plates.
Detailed description of the invention
See Fig. 1, Fig. 2 a, Fig. 2 b and Fig. 2 c, in the present embodiment, the version of the outer collar member of hammer mill end plate is: the outer collar member 3 of end plate is assembled by each covering of the fan part, and each covering of the fan part is assembled in full circle ring along the circumference of disintegrating machine end plate 5; Described covering of the fan part is provided with arc-shaped step face 3a; coordinate with the edges close of disintegrating machine end plate 5 with described arc-shaped step face 3a; form end plate edge protection plate; installing hole 3b is provided with at the inner ring position of described each covering of the fan part; 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, the outer collar member 3 of end plate is 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 the high-abrasive material of 45.
The outer collar member of end plate in the present embodiment position easy to wear implements available protecting to disintegrating machine end plate at its edge, and is combined into complex with disintegrating machine end plate, and can change, available protecting element of installation.
For existing version, when crusher in crushing material, the piece material that a part is broken can be diverted to the two ends of rotor block, the gap location namely between side hammer head 4 and side casing 2, will inevitably cause and washes away the outer peripheral of disintegrating machine end plate 5 and wear and tear; The version provided in the present embodiment is protected with the outward flange of the outer collar member 3 pairs of disintegrating machine end plates 5 of end plate on the one hand; On the other hand, the outer shroud position tapered end face 3c of the outer collar member 3 of end plate matches with the conical surface of the housing back-up ring liner plate 1 be arranged on side casing 2, forms the guide function to material flow, further stops material to enter gap, thus significantly reduces wearing and tearing.
