Abstract
The invention discloses a retainer ring lining plate for a hammer crusher. The retainer ring lining plate for the hammer crusher is characterized in that the retainer ring lining plate is sector-shaped; multiple blocks are distributed at positions, which are close to the periphery of a rotor, on an inner side wall of a side enclosure of the crusher along the semi-circumference; an arc-shaped ribbed retainer ring is arranged on the top of the retainer ring lining plate at a part close to the tip circle of the rotor hammer head; materials are guided to gather to the middle of the rotor together by the arc-shaped ribbed retainer; a conical surface is formed in the lower part of the retainer ring lining plate; and the conical surface is matched with a conical surface of a rotor end disc outer ring. The materials are guided to gather to the middle of the rotor together when the crushing effect of the rotor is not influenced, and the hammer head and end disc on two sides of the rotor and the enclosure are effectively protected, and the service life of related parts is obviously prolonged.
Description
Technical field
The present invention relates to a kind of hammer mill back-up ring liner plate, for the protection of disintegrating machine both sides tup, housing side wall and rotor end plate, improve the service life of tup, casing and rotor end plate.
Background technology
During hammer mill work, the tup of both sides and end plate, except be subject to material impact, wearing and tearing at Rotating cylindrical surface place except, both sides and internal side of shell face also can be subject to material additional corrosion, thus generation synergistic effect, rotor edge tup is caused to be the wearing and tearing of axe shape, premature failure compared with tup in the middle part of rotor; Also easily cause simultaneously end plate outer rim and internal side of shell surface wear serious.Facts have proved above-mentioned adverse effect of preventing if do not managed, will directly affect the service life of associated components.
Hammer mill in the market, does not form available protecting to rotor side surface tup, chassis sidewall and end plate mostly.When broken material, the small size material block after some fragmentations can be easy to the gap entered between the tup of rotor side surface and body, thus the impact formed tup side, end plate and casing and wearing and tearing.
Summary of the invention
The present invention is the deficiency for avoiding existing for above-mentioned prior art; a kind of hammer mill back-up ring liner plate is provided; while not affecting rotor crushing effect; directing material is gathered in the middle part of rotor block; reduce the probability that material enters above-mentioned zone; match with end plate outer ring again, form the available protecting to rotor both sides tup, end plate and casing, to improve the service life of above-mentioned parts.
The present invention is that technical solution problem adopts following technical scheme:
The design feature of hammer mill back-up ring liner plate of the present invention is: described back-up ring liner plate is fan-like pattern, the madial wall of disintegrating machine side casing is distributed with some pieces near rotor periphery along semi-circumference, the top of described back-up ring liner plate is being provided with arc fin back-up ring close to rotor tup tip circle position, gather in the middle part of rotor with described arc fin back-up ring directing material, the bottom of described back-up ring liner plate is the conical surface, matches with the conical surface of the described conical surface with rotor end plate outer ring.
The design feature of hammer mill back-up ring liner plate of the present invention is also:
Be provided with bolt hole in the bottom of the arc fin back-up ring of described back-up ring liner plate, described back-up ring liner plate utilizes described bolt hole to be arranged on the madial wall of disintegrating machine side casing.
Described back-up ring liner plate is by high hardness wear-resisting material monolithic casting.
Its HRC value of high hardness wear-resisting material for casting described back-up ring liner plate is not less than 45.
The present invention is the mode adopting assorted cold dishes combination, is formed together " fire wall ", form effective protection to " wall " interior crusher components at crushing chamber of crusher two ends of rotor place.Compared with the prior art, beneficial effect of the present invention is embodied in:
1, in the present invention, arc fin back-up ring forms certain protective barrier to rotor most both sides tup, prevents material to the stacking abrasion of side tup;
2, the present invention matches with the conical surface of the conical surface with rotor end plate outer ring, has certain stream guide function, can prevent material from entering gap between rotor and housing, can reduce the wearing and tearing to end plate sidewall and body inwall;
3, guide ring liner plate of the present invention adopts high hardness wear-resisting cast to form, and its antiwear property is strong;
4, structure of the present invention simple, processing and manufacturing and simple installation, service efficiency is high, cost is low.

Number in the figure: 1 back-up ring liner plate, 1a arc fin back-up ring, the 1b conical surface, 1c bolt hole, 2 disintegrating machine side casings, 3 rotor end plate outer rings, 4 tups.
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 hammer mill back-up ring liner plate is: back-up ring liner plate 1 is in fan-like pattern, the madial wall of disintegrating machine side casing 2 is distributed with some pieces near rotor periphery along semi-circumference, the top of back-up ring liner plate 1 is being provided with arc fin back-up ring 1a close to rotor tup tip circle position, gather in the middle part of rotor with arc fin back-up ring 1a directing material, the bottom of back-up ring liner plate 1 is conical surface 1b, matches with the conical surface of rotor end plate outer ring 3 with conical surface 1b.
In concrete enforcement, as shown in Fig. 2 b and Fig. 2 c, the back side of back-up ring liner plate 1 is flat type, and be provided with bolt hole 1c in the bottom of the arc fin back-up ring 1a of back-up ring liner plate 1, back-up ring liner plate 1 utilizes on the madial wall of bolt hole 1c breaker mounting side casing 2.
In order to improve anti-wear performance, back-up ring liner plate 1 is by high hardness wear-resisting material monolithic casting, and its HRC value of high hardness wear-resisting material that specifically can arrange for casting back-up ring liner plate 1 is not less than 45.
When crusher in crushing material, the piece material that a part is broken can be diverted to the both sides of rotor, namely between the tup 4 at most two ends and disintegrating machine side casing 2, then will inevitably cause the washing away of both sides tup, end plate edge and casing, wear and tear.By arranging the present embodiment guide ring liner plate, be equivalent to be provided with together " fire wall ", have part obstructs and drainage to material, decrease the probability that material directly contacts with end plate, casing, corresponding component wear is corresponding reduction also.Back-up ring liner plate top is being provided with arc fin back-up ring close to rotor tup tip circle position, and bootable material is gathered in the middle part of rotor block, and its underpart is designed to the conical surface and matches with rotor block end plate outer ring, effectively stops material to enter gap.So, the available protecting to rotor both sides tup, end plate and casing can be formed, prevent Fast Wearing, substantially increase the service life of above-mentioned parts.
