Description

A kind of hammer crusher

Technical field

This utility patent relates to a kind of hammer crusher, usually uses in the industries such as feed, grain, food, chemical industry, medical treatment.

Background technology

This type of pulverizer is usually by feeding hole of pulverizer (1), hammer leaf (2), rotor (3), door (4), pressure screen frame) 5), motor (6), pulverizer discharging opening (7), body (8), sieve (9) etc. form.During work, by motor (6) rotor driven (3), hammer leaf (2) on rotor (3) is rotated, material is constantly pulverized by hammer leaf (2) after charging aperture (1) is come in, qualified powder after pulverizing, through the sieve aperture of sieve (9), is discharged from pulverizer discharging opening (7).

There is following problem in this kind of pulverizer:

1, when material has just entered pulverizer mouth, down, hammer mills rotates along tangential motion direction, garden direction vector, large to the hammering relative velocity of material, crush efficiency is high, material, by after hammer leaf hammering, moves in the same way with hammer leaf, and hammer mills just obviously reduces the relative velocity of material, and relative velocity is little, crush efficiency just reduces.

2, hammer mills makes circumference to rotate, and promote material mobile on sieve surface, the sieve aperture of corresponding hammer leaf easily goes out sieve, but, disintegrator sieving net is wider, hammer leaf thickness only several millimeters, and the screen surface of extreme portions between hammer leaf does not have corresponding hammer leaf, thus corresponding screen surface material moves few, screening effect is poor, and pulverizer yields poorly, and the material uniformity is irregular.

3, hammer leaf is for a long time by frontal impact, and service life is short.

For a long time, this is the crucial problem that puzzlement hammering crushing machine technology improves.

Utility model content

This utility patent object is to provide a kind of hammer crusher, and after requiring hammer mills hammering material, material no longer and then hammer leaf runs around in circles, and in follow-up hammering, requires to keep hammer leaf to the very large relative speed difference of material.Meanwhile, the sieve surface of moving except corresponding hammer leaf keeps a large amount of materials to move, the screen surface of other parts, and the part screen surface namely between hammer leaf, also will keep a large amount of materials to move, thus improves crush efficiency, improves the uniformity of comminuting matter.And hammer leaf service life can be extended.

The key of this utility patent adopts a kind of its structure of newly-designed hammer crusher as follows:

A kind of hammer crusher, is made up of charging aperture (1), hammer leaf (2), rotor (3), door (4), pressure screen frame (5), motor (6), pulverizer discharging opening (7), body (8), sieve (9) etc.Its feature is that described its hammer leaf operative end surface of hammer leaf (2) is tiltedly put the first edge on a knife or a pair of scissors.

Hammer leaf Fig. 5 of pulverizer, hammer leaf is designed to rectangle sheet, and there is pin-and-hole one end, and another operative end surface has the high-abrasive material of hard, and operative end surface is tiltedly put the first edge on a knife or a pair of scissors, and the angle a on the inclined-plane that puts the first edge on a knife or a pair of scissors is between 30-60 degree.When pulverizer works, under the ramp effect in the face of putting the first edge on a knife or a pair of scissors of hammer leaf, push material to side, reduce the movement velocity that material follows hammer leaf to rotate, material creates horizontal motion, when the hammer leaf of the follow-up of another grade and material again hammering time, material and hammer leaf form the knocking state of near vertical, very high knocking speed difference can be obtained, improve crush efficiency; Simultaneously, hammer leaf rotates, except pushing portion material is except sieve surface is moved with the hammer leaf direction of motion, also partial material is driven to be displaced sideways on sieve surface, like this, add at the area of sieve surface material movement, and sieve the increase of surface material migration area, favourable increase yield, improves the uniformity of material.Because hammer leaf operative end surface adopts inclined-plane, reduce material frontal impact, service life extends.For guaranteeing material transverse movement, the direction of putting the first edge on a knife or a pair of scissors that the one group of hammer leaf requiring each coaxial is consistent, another group hammer leaf corresponding can adopt rightabout, to keep rotor symmetrical balance, phase difference between the group that hammer leaf direction is different, can generation time poor, make material do moving left and right of horizontal phase in screen surface, add screening effect.The hammer leaf of Fig. 5, Fig. 6 can match use, when one group of hammer leaf adopt Fig. 5 put the first edge on a knife or a pair of scissors direction time, corresponding one group must adopt Fig. 6 direction, preserves balance.Fig. 7 can install pairing use in positive and negative.This utility patent also can adopt and a kind ofly be provided with the pulverizer (Fig. 3) determining hammer, like this, when material is when sieving surface lateral and moving, produces hammering and shear action with fixed hammer the into shape of side.Also the pulverizer (Fig. 4) of a kind of screen cloth vibration can be loaded onto, it is characterized in that pressure screen frame (5) below is provided with vibrating motor, this vibrating motor (11) is connected with pressure screen frame (unit), make pressure screen frame (unit) and sieve (9) can Independent Vibration by isolation mountings such as springs, crushing effect be better.
