Abstract

A kind of hammer crusher, mainly comprise charging aperture (1), hammer leaf (2), rotor (3), epitrochanterian rotating disk (4), blade (5), motor (6), pulverizer discharging opening (7), body (8), sieve (9), door (10), pressure screen frame (11), wherein, air blade (5) is added with between rotating disk and rotating disk, 2 are had to become 180 degree of one linear installation between every grade, the fan blade of adjacent two grades is in right angle, rotating disk (4) is going out out several air vent near rotating shaft, like this, when the rotor rotates, wind can from the gap location air intake of pulverizer both sides axis hole, again through the air vent of rotating disk, under the agitating of fan blade, the partial material remaining in the lost motion of rotor center is shifted rapidly onto hammer leaf end place by hammering crushing, simultaneously, a kind of blast of pulsatile change is provided by fan blade, destroy the uniform centrifugal force of material ring and the negative pressure outside sieve in sieve, thus improve the uniformity of output and material, improve stifled sieve phenomenon.

Description

Hammer crusher

Technical field

The present invention relates to a kind of hammer crusher, usually at feed, grain, food, chemical industry, uses in the industries such as medical treatment.

Background technology

This type of pulverizer usually by feeding hole of pulverizer (1), hammer leaf (2), rotor (3), be contained in epitrochanterian rotating disk (4), motor (6), pulverizer discharging opening (7), body (8), sieve (9), door (10), pressure screen frame (11) 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, material enters after in pulverizer, and material is with hammer leaf circular motion in the same way, and under the influence of centrifugal force, sieve surface formation material ring, the centrifugal force of material ring, equably towards sieve aperture, has the trend of stifled sieve aperture, and unfavorable qualified material goes out sieve in time; Pulverizer discharging opening has negative sub-air draught usually, and the outer uniform negative pressure of sieve is also unfavorable for sieving stirring of interior putty particle.

2, in rotor mill centre, have the material lagging of considerable part to roll all the time, because the radius of rotor center is little, between material, the linear velocity of percussion is little, and the material of central part is in lost motion state all the time.

Due to above 2 points, cause pulverizer to yield poorly, the uniformity is poor, and for a long time, this is one of crucial problem for puzzlement pulverizer technology raising.

Summary of the invention

The object of the invention is to provide a kind of hammer crusher, require in pulverizer, the blast of other a kind of change can be produced, make uniform centrifugal force in sieve give to destroy with the negative pressure outside sieving, produce anti-blocking up and sieve effect, simultaneously, the partial material of the heart in the rotor of rolling will be detained, shift rapidly hammer leaf end place onto, by high speed hammering crushing, thus reach the object improving output, improve the uniformity, prevent stifled sieve.

Key of the present invention increases fan blade in the rotating disk of rotor mill.Structure is as follows:

See Fig. 1, Fig. 2, by feeding hole of pulverizer (1), hammer leaf (2), rotor (3), is contained in epitrochanterian rotating disk (4), blade (5), motor (6), pulverizer discharging opening (7), body (8), sieve (9), door (10), pressure screen frame (11).

In figure, rotor (3) is equipped with multi-disc rotating disk (4), fan blade is arranged between rotating disk, between every 2 rotating disks, 2 fan blades are installed, the direction of two panels fan blade is 180 degree, also equal with the distance in the center of circle on the same straight line crossing the center of circle, the fan blade at the interval of adjacent discs is mounted to 90 degree and interlocks, rotating disk (4) is leaving several air vent near rotating shaft place, like this, when the rotor rotates, wind can from the gap location air intake of pulverizer both sides axis hole, again through the air vent of rotating disk, under the agitating of fan blade, the partial material of rotor center will be remained in, shift rapidly hammer leaf end place onto and allow high speed hammering crushing, simultaneously, adjacent discs becomes 90 degree of staggered fan blades, not only can form the wind pressure pulsation of vertical direction at sieve inner surface but also the blast motion of horizontal phase can be formed, destroy the centrifugal force of material ring in sieve and the negative pressure outside sieve, qualified material is made more easily to go out sieve, thus significantly improve crush efficiency, improve the uniformity of material, prevent stifled sieve, reach object of the present invention.

Accompanying drawing explanation

Fig. 1, illustrate a kind of horizontal hammer crusher, feeding hole of pulverizer (1), hammer leaf (2), rotor (3), rotating disk (4), fan blade (5), motor (6), pulverizer discharging opening (7), body (8), sieve (9), door (10), pressure screen frame (11).

Specific embodiment:

Embodiment 1: Fig. 1, Fig. 2, a kind of horizontal pulverizer, feeding hole of pulverizer (1), hammer leaf (2), rotor (3), is contained in the compositions such as epitrochanterian rotating disk (4), fan blade (5), motor (6), pulverizer discharging opening (7), body (8), sieve (9), door (10), pressure screen frame (11).Its rotor Fig. 3, fan blade is arranged between rotating disk, between every 2 rotating disks, 2 fan blades are installed, the direction of two panels fan blade is 180 degree, on the same straight line crossing the center of circle, and it is equal with the distance in the center of circle, the fan blade at the interval of adjacent discs becomes 90 degree to interlock, like this, not only can form the wind pulse of vertical direction at sieve inner surface but also the wind motion of horizontal phase can be formed, destroy the negative pressure outside uniform centrifugal force and sieve in sieve, make qualified material more easily go out sieve, thus significantly improve crush efficiency, improve the uniformity of comminuting matter.

The rotor of this band fan blade also can be contained on the pulverizer that screen cloth can vibrate, and also can be contained in on the pulverizer determining hammer and other various pulverizer.The length change, number change, setting angle change etc. of any fan blade are all involved.

Beneficial effect:

The pulverizer of fan blade is housed, when rotor rotates, wind from the gap location air intake of pulverizer both sides axis hole, then can pass the air vent of rotating disk, under the agitating of fan blade, to the partial material of rotor center be remained in, shift rapidly hammer leaf end place onto, simultaneously, by the fan blade staggered, a kind of blast of pulsatile change is provided, destroys uniform centrifugal force and the negative pressure outside sieve in sieve, make qualified material more easily go out sieve.Thus significantly improve crush efficiency, improve the uniformity of comminuting matter, to the stifled sieve phenomenon improving the materials such as little sieve aperture, fine powder material, high-moisture, high microsteping, effect is obvious especially.
