Abstract

The utility model discloses a hammer piece grinder, comprising a feeding port (1), a hammer piece (2), a rotor (3), rotating discs (4), a motor (6), a discharging port (7), a machine body (8), sieve blades (9), a gate (10) and a sieve-pressing frame (11), wherein the rotor is driven by the motor. The hammer piece grinder is characterized in that fan blades (5) are arranged among the rotating discs (4) arranged on the rotor (3); and a vent hole (12) is arranged at the position of the rotating disc (4), close to a rotating shaft. When the rotor rotates, wind can enter from a gap of axle holes at the two sides of the grinder, then passes through the vent hole of the rotating disc, and quickly pushes part of invalid-movement materials which are left at the center of the rotor to the end of the hammer piece to be ground by the hammer piece; and simultaneously, the fan blades provide wind pressure with variable pulsation to damage the uniform centrifugal force of a material ring in a sieve and the negative pressure outside the sieve, so that the yield and the uniformity of materials are improved, and the sieve is prevented from being blocked.

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

Pulverizer of the prior art usually by charging aperture, hammer leaf, rotor, be contained in epitrochanterian rotating disk, motor, discharging opening, body, sieve sheet, door, press screen frame etc. to form.During work, drive rotor by motor, make epitrochanterian hammer leaf rotation, material is constantly pulverized by hammer leaf after charging aperture is come in, and the qualified powder after the pulverizing passes the sieve aperture of sieve sheet, discharges from the pulverizer discharging opening.

There is following problem in this class pulverizer:

1, after material advanced in the pulverizer, material was with hammer leaf circular motion in the same way, and under action of centrifugal force, the sieve surface forms the material ring, and the centrifugal force of material ring has the trend of stifled sieve aperture equably towards sieve aperture, and unfavorable qualified material in time goes out sieve; The pulverizer discharging opening has negative inferior air draught usually, and the outer negative pressure uniformly of sieve also is unfavorable for sieving stirring of interior putty particle.

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

Because above defective causes pulverizer to yield poorly, the uniformity is poor, and for a long time, this is one of crucial difficult problem of puzzlement pulverizer technology raising.

Summary of the invention

The object of the invention provides a kind of hammer crusher, can produce a kind of blast of variation, make interior centrifugal force uniformly of sieve and the outer negative pressure of sieve give destruction, produce anti-stifled sieve effect, simultaneously, delay is rolled in the partial material of rotor center, shift hammer leaf end place rapidly onto, pulverize by the high speed hammer leaf, reach the effect that improves output, improves the uniformity, prevents to block up sieve.

The utility model comprises charging aperture, hammer leaf, rotor, rotating disk, motor, discharging opening, body, sieve sheet, door, presses screen frame, rotor is driven by motor, it is characterized in that being installed between the epitrochanterian rotating disk and be provided with fan blade, described rotating disk is axially having air vent near rotating shaft place.

2 fan blades are installed between adjacent discs, and the setting angle of two fan blades is 180 degree, and is also equal with the distance in the center of circle on the same straight line of crossing the center of circle.Fan blade also can the multi-disc symmetry be installed.Fan blade between adjacent 2 pairs of rotating disks becomes the staggered installation of 90 degree.Rotating disk is being provided with air vent near rotating shaft place.Owing on the rotor multi-disc rotating disk is housed, fan blade is installed between the rotating disk, 2 fan blades are installed between 2 rotating disks, two fan blades are 180 degree and install, also equal on the same straight line of crossing the center of circle with the distance in the center of circle, it is staggered that adjacent 2 pairs of rotating disks fan blade at interval is mounted to 90 degree, rotating disk is axially having several air vents near rotating shaft place, like this, when rotor rotated, wind can be from the gap location air intake of pulverizer both sides axis hole, pass the air vent of rotating disk again, under the agitating of fan blade, will remain in the partial material of rotor center, shift hammer leaf end place rapidly onto and allow the high speed hammer leaf pulverize; Simultaneously, adjacent 2 pairs of rotating disks are the staggered fan blade of installing of 90 degree, sieving the blast motion that inner surface not only can form the wind pressure pulsation of vertical direction but also can form horizontal phase, destroyed the centrifugal force and the outer negative pressure of sieve of material ring in the sieve, make that qualified material is easier to go out sieve, thereby obviously improve crush efficiency, improve material the uniformity, prevent stifled sieve, reach the purpose of this utility model.

Specific embodiment:

Below in conjunction with accompanying drawing narration specific embodiment.The utility model by charging aperture 1, hammer leaf 2, rotor 3, be contained in epitrochanterian rotating disk 4, fan blade 5, motor 6, pulverizer discharging opening 7, body 8, sieve sheet 9, door 10, press screen frame 11 etc. to form.Fan blade 5 is installed between the rotating disk 4, and the setting angle that 5, two fan blades of 2 fan blades are installed between per 2 rotating disks is 180 degree, on the same straight line of crossing the center of circle, and equal with the distance in the center of circle, adjacent 2 pairs of rotating disks fan blade 5 at interval is the staggered installation of 90 degree.Rotating disk 4 is axially having air vent 12 near rotating shaft place.Like this, sieving the wind motion that inner surface not only can form the wind pulse of vertical direction but also can form horizontal phase, destroy in the sieve centrifugal force and the outer negative pressure of sieve uniformly, made that qualified material is easier to go out sieve, thereby effectively improved 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 installed in to have on the pulverizer of deciding hammer and other various pulverizers.The shape in hole, number change etc. all should be included within the utility model protection domain on the length variation of any fan blade, number change, setting angle variation etc. and the rotating disk.
