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 protect disintegrating machine both sides tup, housing side wall and
Rotor end plate, improves the service life of tup, casing and rotor end plate.
Background technology
During hammer mill work, the tup of both sides and end plate, in addition to being subject to material impact, abrasion at Rotating cylindrical surface,
Both sides and internal side of shell face also can be subject to material additional corrosion, thus producing synergistic effect, cause rotor edge tup
Wear and tear in axe shape, premature failure compared with tup in the middle part of rotor；Also easily cause end plate outer rim and internal side of shell surface wear simultaneously
Seriously.Facts have proved as being not seeking to above-mentioned adverse effect of preventing, the service life of associated components will be directly affected.
Hammer mill in the market, does not form effectively to rotor side surface tup, chassis sidewall and end plate mostly
Protection.In broken material, the small size material block after some are broken can easily enter between the tup of rotor side surface and body
Gap, thus being formed to the impact of tup side, end plate and casing and abrasion.
Content of the invention
The present invention is for avoiding the deficiency existing for above-mentioned prior art, providing a kind of hammer mill back-up ring liner plate,
While not affecting rotor crushing effect, directing material is gathered in the middle part of rotor block, reduces material and enters the general of above-mentioned zone
Rate, then match with end plate outer ring, form the effective protection to rotor both sides tup, end plate and casing, to improve above-mentioned part
Service life.
The present invention is to solve technical problem to adopt the following technical scheme that
Being structurally characterized in that of hammer mill back-up ring liner plate of the present invention: described back-up ring liner plate is in fan-like pattern, in disintegrating machine
It is distributed with some pieces near rotor periphery along semi-circumference, the top of described back-up ring liner plate turns close on the medial wall of side casing
Sub- tup tip circle position is provided with arc fin back-up ring, is gathered in the middle part of rotor with described arc fin back-up ring directing material, described
The bottom of back-up ring liner plate is the conical surface, is matched with the conical surface of rotor end plate outer ring with the described conical surface.
The construction featuress of hammer mill back-up ring liner plate of the present invention lie also in:
It is 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 is arranged on the medial wall of disintegrating machine side casing.
Described back-up ring liner plate is by high hardness wear-resisting material integral casting forming.
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 by the way of assorted cold dishes combination, is formed together " fire wall " at crushing chamber of crusher two ends of rotor,
To " wall ", interior crusher components form and are effectively protected.Compared with the prior art, the present invention has the beneficial effect that:
1st, in the present invention, arc fin back-up ring forms certain protective barrier to rotor both sides tup it is therefore prevented that material pair
The stacking abrasion of side tup；
2nd, the present invention is matched with the conical surface of rotor end plate outer ring with the conical surface, has certain stream guide function, permissible
Prevent material from entering the gap between rotor and housing, the abrasion to end plate side wall and body inwall can be reduced；
3rd, guide ring liner plate of the present invention is formed using high hardness wear-resisting cast, and its antiwear property is strong；
4th, present configuration is simple, processing and manufacturing and simple installation, service efficiency be high, low cost.

In figure label: 1 back-up ring liner plate, 1a arc fin back-up ring, the 1b conical surface, 1c bolt hole, 2 disintegrating machine side casing, 3 turns
Sub- end plate outer ring, 4 tups.
Specific embodiment
Referring to 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: gear
Circle liner plate 1 is in fan-like pattern, is distributed with some pieces near rotor periphery along semi-circumference on the medial wall of disintegrating machine side casing 2,
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, with arc fin back-up ring 1a guiding
Material is gathered in the middle part of rotor, and the bottom of back-up ring liner plate 1 is conical surface 1b, is matched with the conical surface of conical surface 1b and rotor end plate outer ring 3
Close.
In being embodied as, as shown in Fig. 2 b and Fig. 2 c, the back side of back-up ring liner plate 1 is flat type, in the arc of back-up ring liner plate 1
The bottom of shape fin back-up ring 1a is provided with bolt hole 1c, and back-up ring liner plate 1 utilizes the inner side of bolt hole 1c breaker mounting side casing 2
On wall.
In order to improve anti-wear performance, back-up ring liner plate 1 is by high hardness wear-resisting material integral casting forming, specifically can arrange
Its hrc value of high hardness wear-resisting material 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, i.e. two ends
Tup 4 and disintegrating machine side casing 2 between, then will necessarily cause washing away, grinding to both sides tup, end plate edge and casing
Damage.By arranging the present embodiment guide ring liner plate, be equivalent to and be provided with together " fire wall ", material is had part stop and drain
Effect, decreases material and end plate, the probability of casing directly contact, and corresponding component wear also accordingly reduces.Back-up ring liner plate top
It is being provided with arc fin back-up ring close to rotor tup tip circle position, bootable material is gathered in the middle part of rotor block, its underpart is designed
Match with rotor block end plate outer ring for the conical surface, effectively stop material from entering gap.So, can be formed to rotor both sides tup,
End plate and the effective protection of casing, prevent Fast Wearing, substantially increase the service life of above-mentioned part.
