Abstract

The utility model discloses a crusher hammer sheet, which comprises a hammer sheet body which is provided with a clamping hole connected with a shaft on the crusher rotor. The working end of the hammer sheet body is also provided with hammer teeth fixedly connected with the hammer sheet body. The hammer teeth are made of hard alloy materials, and the inner side of the clamping hole arranged on the hammer sheet body is also provided with a circular abrasion-proof inner sleeve or one side adjacent to the end head of the hammer sheet body is provided with a semicircular abrasion-proof inner sleeve. Because the hammer teeth arranged on the working end of the novel crusher hammer sheet body are made of hard alloy materials, and the hard alloy materials has high hardness, strong corrosion resistance, good oxidation resisting effect, etc., the hammer teeth made of the hard alloy materials have good shock resistance and abrasion resistance, the abrasion resistance is about ten times of iron and the useful service life and the crushing efficiency of the crusher hammer sheet are improved effectively. In addition, the hard alloy is easy to weld on the hammer sheet body, and the bond degree of the hard alloy and the hammer sheet body is good; the cost is low, and the manufacturing technique is simple.

Description

Hammer mills

(1) technical field:

The utility model relates to the parts on the pulverizer, specifically hammer mills.

(2) background technology:

Pulverizing is the important procedure that industries such as grain, feed, beverage, medicine are processed root, stem, the leaf of granule materials or plant, pulverizes processing and is finished by pulverizer usually.The kind of pulverizer is more, the pulverizer that generally adopts mostly is beater disintegrating machine greatly at present, hammer leaf on the pulverizer is installed on the axle of rotor mill, hammer tooth and the material of the working end of the main hammer leaf that relies on the high speed circular motion on it clash into repeatedly, rub in crushing process, to reach the purpose with the material pulverizing.The existing hammer leaf that generally uses forms by common ferrous materials high melt casting, this hammer leaf made from the ordinary steel iron material, its hardness is lower, anti-wear performance is also relatively poor, carry out in the long-time non-stop run process at pulverizer, owing to constantly produce strong bump and friction between hammer leaf and the material, caused hammer leaf itself also to suffer wearing and tearing significantly, especially hammer odontotripsis of working end gets the most violent on it, after the hammer tooth of the working end of hammer leaf is subjected to bigger wearing and tearing, can make the crush efficiency of hammer leaf significantly reduce, also just increase the time of pulverizing processing simultaneously, cause the operating efficiency of pulverizer to descend greatly, seriously even also can have influence on the operate as normal of pulverizer, so the hammer leaf of beater grinder belongs to main consumable accessory, in crushed work, the hammer leaf of the replacing pulverizer of having to frequent often is to keep the operate as normal efficient of pulverizer.

(3) utility model content:

The utility model will disclose a kind of simple in structure, crush efficiency is high, anti-wear performance hammer mills preferably.

This novel hammer mills, comprise the hammer leaf body, which is provided with rotor mill on the hole clipping that is connected of axle, also be provided with the hammer tooth that is connected with it on the working end of hammer leaf body, different is: described hammer tooth is that Hardmetal materials is made, because Hardmetal materials has advantages such as hardness height, anti-wear performance are good, therefore its impact resistance of hammer tooth, the friction, capability made from Hardmetal materials is strong especially, and wear-resisting effect can increase substantially; Because the hammer leaf body is by hole clipping set on it, cutting ferrule is on the axle of rotor mill, for the hole clipping that reduces the hammer leaf body is worn and torn, can also be on the hammer leaf body set hole clipping inboard, be provided with and circular overlap in wear-resisting, or be provided with in the hole clipping inboard, near one side of hammer leaf working end semicircular wear-resisting in cover, the metal material manufacturing that this wear-resisting interior cover should be higher by hardness, anti-wear performance is stronger; Because the hammer tooth that is connected with hammer leaf body working end needs to carry out repeatedly high-speed impact, friction with material, so the hammer tooth must firmly and not can come off with being connected of hammer leaf body, therefore can be with the hammer tooth made with Hardmetal materials with welding or otherwise be connected with hammer leaf body working end, can certainly welding one deck on the working end of existing hammer leaf body and working end and on hammer odontoid and the corresponding to Hardmetal materials of structure into shape; The hammer tooth made from Hardmetal materials can be distributed on the working end side of hammer leaf body arbitrarily, for example can stepped distribution thereon; And can with the hammer leaf body arbitrarily the hammer tooth on working end adopt the Hardmetal materials manufacturing, can certainly all adopt Hardmetal materials to make in the hammer tooth on four working ends of hammer leaf body according to actual needs; So after the hammer tooth made from Hardmetal materials on the working end is worn and torn fully, can change another working end replaces, promptly make a slice hammer leaf can be used as four and use, so both improved the Acceptable life of hammer leaf, also saved production cost accordingly; Because the working edge that is positioned on the hammer leaf body working end, is connected as a single entity with the hammer tooth is when hammer leaf body high-speed motion, also can produce bump, friction with material, therefore can also also adopt Hardmetal materials to make the working edge that is connected with the hammer tooth, to increase its anti-wear performance; And the hammer tooth made from Hardmetal materials on the hammer leaf body can be shape arbitrarily, its crown also can be crown at any angle, in order to improve the effect of pulverizing, the crown of hammer tooth can be made acute angle, for example make the acute angle crown that projects upwards or give prominence to the working edge outside, or make the acute angle crown of other form, so that can quickly material be pulverized; It is wear-resisting, the impact resistance ability is far longer than the hammer leaf body made from the ordinary steel iron material because with the hammer tooth of carbide alloy manufacturing; in order to protect the hammer leaf body; also the hammer tooth made with Hardmetal materials and the thickness of the working edge that links to each other with the hammer tooth all can be made thickness greater than the hammer leaf body; so both can increase the contact area of hammer tooth and material; improve the efficient of pulverizing, can be reduced in again and pulverize the suffered wearing and tearing of hammer leaf body in the process.

Set hammer tooth is to be made by Hardmetal materials on the working end of this novel hammer mills body, because the hardness height of Hardmetal materials, rotproofness is strong, effect such as anti-oxidant is all better, so have impact resistance preferably with its hammer tooth of making, anti-wear performance, and its wear-resistant ability is about 10 times of iron, make the contact site of hammer leaf body and material become more wear-resisting, the Acceptable life and the crush efficiency of hammer mills have also been improved effectively, and carbide alloy is hammered into shape the thickness thickening of tooth and connected working edge, make that the contact-making surface of hammer tooth and material is bigger, and crown is made sharp acute angle-shaped, also make the hammer dental transition add and be easy to material is pulverized, therefore also further improved the crush efficiency of hammer leaf; And carbide alloy also easier is welded on the hammer leaf body, and the conjugation of itself and hammer leaf body is also fine; Reach the working edge that connects as one with it owing to only carbide alloy is used to make the hammer tooth, also increase seldom, and the difficulty of welding is little, manufacturing process is also simpler, therefore can carry out industrialized mass production fully so make the cost of hammer leaf.
