Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is done further explanation:

Fig. 1 is a front view of the present invention;

Fig. 2 is a vertical view of the present invention;

Fig. 3 be among Fig. 1 A-A to profile;

Fig. 4 is the vertical views of 2 rotors in lower house.

Among the figure: 1 housing, 11 upper shells, 12 lower houses, 2 charging apertures, 3 rotors, 31 rotor disks, 32 flat keys, 33 main shafts, 34 main shaft distance bushings, 35 bearing pins, 36 hammer leaves, 37 hammer leaf spacers, 4 motors, 5 sieve sheets, a distance that axially misplaces.

The specific embodiment

Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of twin shaft pulverizer comprises housing 1, charging aperture 2, rotor 3 and motor 4, and its rotor 3 has two, and they flatly are arranged in parallel within the housing 1, also are provided with rotor disk 31 on the rotor 3; But each rotor correspondence is provided with a motor rotating at high speed 4, two altogether, and these two equidirectional runnings of motor,, promptly direction of rotation is identical.And each motor can just change or reverse, to adapt to different feeding mechanisms.

Rotor disk 31 can be provided with 17; They evenly are nested with on main shaft 33 through flat key 32; Be provided with main shaft distance bushing 34 between the adjacent rotors dish 31 in twos; Each rotor disk 31 upper edge rotor disk 31 circumferentially is uniformly distributed with six hammer leaves 36, is provided with hammer leaf spacer 37 between each hammer leaf 36 and the adjacent rotors dish 31, and the six roots of sensation is serially connected these 17 rotor disks 31 along the bearing pin 35 that rotor 3 circumferentially is uniformly distributed with hammer leaf 37.

Two rotors 3 are that 10mm installs along the axial dislocation of rotor 3 apart from a, hammer leaf interlaced arrangement like this, and crushing effect is more obvious.

Charging aperture 2 is provided with two, and is positioned at housing 1 top, can select to use which charging aperture according to different feeding mechanisms, also can carry out feeding simultaneously by two charging apertures.

Can also housing 1 be arranged to two parts: upper shell 11 and lower house 12, and connect through bolt, upper shell 11 is movably arranged on the lower house 12, for convenience detach, maintenance.

During use, like Fig. 3, Fig. 4, suppose to select the charging aperture feeding on the left side, this moment, motor should turn clockwise, and was rotation at a high speed, drove two equidirectional high speed rotations of rotor.After material gets into; Partial material receives moving to from left to right between two rotors after the epitrochanterian hammer leaf in left side clashes into and drops from top to bottom, and the left-hand component of the rotor on the right has been carried out bump from bottom to top to the partial material that falls again at this moment, forms the strong bump of double linear speed; Material moment change direction falls on the sieve sheet 5 from the right side of the son of turning right from top to bottom; This moment, most materials reached the granularity that needs, and fell from sieve sheet 5, had reduced the impact to sieve sheet 5; The thick material of residue minority continues rotation under the action of high-speed airflow of the high speed rotation formation of right side rotor, until reaching the granularity that needs.If use the charging aperture on the right, the course of work is the same, just material traffic direction and motor rotation direction and above-mentioned opposite.Two charging aperture while blankings also can play the effect of pulverizing.
