Description

A kind of fine pulverizer

Technical field

The utility model relates to the manufacture field such as feed, grain, more specifically, relates to a kind of fine pulverizer.

Background technology

During pulverizer work, main shaft rotor driven rotates and then drives hammer leaf high-speed rotation, hammer leaf centrifugal development.Material enters pulverizing chamber from the charging aperture at pulverizer top, first enters accelerating region, at accelerating region, the decrease speed of material is lower, contact with hammer leaf when entering pulverizing chamber, the linear velocity of hammer leaf is higher, broken because both huge speed differences cause material to overwhelm; Then enter at full speed district, material flies to hammer leaf under the influence of centrifugal force, again collides with hammer leaf, becomes granule by bulky grain, and pulverized small particles material, through the sieve aperture of sieve, under the effect of gravity and auxiliary air draft system, is discharged from discharging opening.At present, the most pulverized particles of the pulverizer that market uses is comparatively large, also needs to carry out separating twice, which not only adds cost, and have a strong impact on operating efficiency for some material.

Utility model content

The purpose of this utility model is to provide a kind of fine pulverizer, and pulverized particles is meticulous, without the need to secondary operations, effectively improves operating efficiency, and this mill structure is simply compact.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of fine pulverizer, comprise and pulverize staving and rotor, described rotor comprises the main shaft being located at rotor center and the multiple back shafts arranged around main shaft, and described back shaft is all fixed on two ends of rotor, and described back shaft is evenly provided with some hammer leaves, described pulverizing bucket outer wall offers air inlet, described rotor also comprises some gripper shoes be installed on main shaft, and meanwhile, described gripper shoe extends to and is connected with described back shaft, further, described gripper shoe is provided with air inlet structure.

Further, enough enter pulverize in staving to make wind energy, described air inlet is positioned to be pulverized on the sidewall of staving perpendicular to described rotor rotation centerline.

Further, in order to the abundance guaranteed air intake, the enough materials pulverizing acceleration drive sinking in staving of the wind energy simultaneously entered rise and rotate, be convenient to further pulverizing, described air inlet structure is at least provided with 2, and the distance of described air inlet structure distance rotor rotation centerline is equal with the distance of described air inlet distance rotor rotation centerline.

Further, fully hit fragmentation for the ease of material by hammer leaf, and ensure the simple and compact for structure of pulverizer, described gripper shoe is positioned at the interval of described hammer leaf.

Compared with prior art, the beneficial effects of the utility model are:

The utility model is by offering air inlet at grinding barrel body sidewall, extraneous wind can be entered and pulverize in staving, air inlet structure is set on rotor simultaneously, the High Rotation Speed of rotor is utilized to drive the wind of coming in of air inlet to rotate, the rotation thus the material sunk in drive staving rises, is convenient to the fine crushing of material, effectively improves the efficiency of crushing material, meanwhile, multiple air inlet structure can ensure sufficient intake.Further, this utility model is simple and compact for structure, and convenient operation uses.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

Consult shown in Fig. 1 and Fig. 2, a kind of fine pulverizer, comprise and pulverize staving 1 and rotor 2, this rotor 2 comprises the main shaft 201 being located at rotor 2 center and the multiple back shafts 202 arranged around main shaft 201, this multiple back shaft 202 is all fixed on rotor 2 two ends, and on back shaft 202, be evenly provided with some hammer leaves 203, for comminuting matter, simultaneously in order to make the material of sinking better be pulverized, offer air inlet 101 at pulverizing staving 1 outer wall, extraneous wind energy is entered into and pulverizes in staving 1.

This rotor 2 also comprises some gripper shoes 204 be installed on main shaft 201, gripper shoe 204 extends to and is connected with back shaft 202, like this can fixed support plate 204 along with rotor 2 together High Rotation Speed, simultaneously, gripper shoe 204 is provided with air inlet structure 205, and the air inlet structure 205 in the present embodiment is set to circular through hole.And, the distance of through hole distance rotor 2 rotation centerline is equal apart from the distance of rotor 2 rotation centerline with air inlet 101, can so that the wind of air inlet well enters in pulverizing staving 1, when rotor 2 High Rotation Speed, gripper shoe 204 rotates together along with rotor 2, often turning around through hole all can through air inlet, at this moment, extraneous wind will enter under the effect of atmospheric pressure to be pulverized in staving 1, enter the wind pulverizing staving 1 in rotor 2 high-speed rotation, produce larger wind-force thus drive the material rising of sinking to rotate, material again rising rotary collision hammer leaf 203 is pulverized.

In addition, in order to ensure the simple and compact for structure of this pulverizer, this gripper shoe 204 is located at the interval of hammer leaf 203.

The above embodiments are only preferred embodiment of the present utility model, can not limit interest field of the present utility model with this, and therefore, the equivalent variations done according to the utility model claim, still belongs to the scope that the utility model is contained.
