Abstract
The utility model discloses a horizontal grinding machine of a water-dropping type grinding room, which belongs to the field of feed processing machinery and aims to solve the problem that the stable circulation layer in the prior art causes the reduction in the performance of the grinder. The hammer-slice grinder includes a rotor, hammer slices and a sieve piece, wherein the hammer slices are distributed on the outer periphery of the rotor, the sieve piece wraps the rotor from the outside to form a water-dropping type grinding room, and a damping device is arranged on the sieve piece and at the bottom of the grinding room; the damping device includes a straight line section and an arc section, wherein the straight line section is inclined downwards, one end of the arc section is connected with the straight line section, and the other end of the arc section is tilted in the direction of the central line of the rotor; and the straight line section and the arc section can be sieve pieces or baffles. The arc section of the grinder can throw material on the outer layer to the striking end of the hammer slices, breaks the circulation layer, and enhances the striking and grinding chance, thereby greatly improving the efficiency of the grinder. The horizontal grinding machine has the advantages of simple structure, convenient manufacture and low cost.
Description
Technical field
The utility model relates to the hammer crusher in a kind of feed manufacturing machine field, particularly a kind of horizontal pulverizer of droplet-shaped pulverizing chamber.
Background technology
At present, feed is pulverized the main beater disintegrating machine that adopts of processing, be provided with rotor in its pulverizing chamber, hammer leaf is evenly distributed on the excircle of rotor, and the rotor periphery is provided with the sieve sheet of the densely covered mesh that surrounds rotor.During pulverizer work, material enters pulverizing chamber, external power source drives the rotor high-speed rotation, with epitrochanterian hammer leaf centrifugal development, smashes material by hammer leaf, material flies to the sieve sheet under action of centrifugal force, bump once more with the sieve sheet, become granule by bulky grain, pulverized small particles material passes the sieve aperture of sieve sheet, under the effect of aspirator, discharge from discharging opening.Because material when doing the high speed centrifugation motion, can become a circulation layer along the compass screen surface rotation by type.Circulation layer has not only reduced the relative velocity that hammer leaf hits material, has weakened the validity of hitting, and the material that is in the circulation layer periphery broken away from the strike of hammer leaf, and it is very big that smashing capability is descended.
" the modern feed processing technology " the 233rd page that publish in October, 2003, announced the horizontal hammer crusher of a kind of droplet-shaped, this pulverizer adopts water droplet shape pulverizing chamber, promptly sieve sheet and be water droplet shape parcel rotor, make import department more help the physical alterations direction of material, the rounded structure in pulverizing chamber bottom.This pulverizer is very little to the destruction of material circulation layer, and circulation layer is still more stable, has reduced smashing capability.
The utility model content
For solving the problem that the stable circulation layer causes the pulverizer performance to descend in the prior art, the utility model provides a kind of horizontal pulverizer of droplet-shaped pulverizing chamber, can improve crush efficiency.
For solving above technical problem, the horizontal pulverizer of a kind of droplet-shaped pulverizing chamber provided by the utility model, comprise rotor, hammer leaf and sieve sheet, hammer leaf is distributed on the excircle of rotor, and the sieve sheet forms water droplet shape pulverizing chamber from outside parcel rotor, the sieve sheet is provided with damping unit, described damping unit is positioned at the bottom of sieve sheet, comprises straightway and arc section, and straightway is downward-sloping, one end of arc section links to each other with straightway, and the other end is to the perk of rotor centerline direction.
As a kind of embodiment of the present utility model, described straightway and arc section can be the extension of sieve sheet.This position still is provided with the sieve sheet, can increase rubbing machine meeting of material and sieve sheet, increases compass screen surface and amass.
As another kind of embodiment of the present utility model, described straightway and arc section can also be baffle plate.This position is set to baffle plate, is beneficial to install and fix and wear-resistant.
With respect to prior art, the utility model has been obtained following beneficial effect: influenced by self gravitation, the radius maximum of material circulation layer when the pulverizing chamber bottom, be that material breaks away from hammer leaf strike end most, especially large granular materials is because the heavier skin that is positioned at more of weight, damping unit is located at that blockage effect is best herein, arc section can will be positioned at outer field material and throw to hammer leaf strike end, destroyed circulation layer, strengthened and hit the chance of pulverizing, pulverizer efficient is improved significantly, and simple in structure, easily manufactured, with low cost.
Description of drawings
Fig. 1 is the structural representation of the horizontal pulverizer of the utility model droplet-shaped pulverizing chamber.
Among the figure: 1 hammer leaf, 2 rotors, 3 sieve sheets, 4 straightways, 5 arc sections.
The specific embodiment
As shown in Figure 1, the horizontal pulverizer of droplet-shaped pulverizing chamber of the present utility model comprises rotor 2, hammer leaf 1 and sieve sheet 3, hammer leaf 1 is distributed on the excircle of rotor 2, and sieve sheet 3 forms water droplet shape pulverizing chamber from outside parcel rotor, and the bottom of pulverizing chamber is provided with the damping unit that destroys circulation layer.Damping unit comprises straightway 4 and arc section 5, and straightway 4 is downward-sloping, and an end of arc section 5 links to each other with straightway 4, and the other end is to the perk of rotor centerline direction.Straightway 4 and arc section 5 can also can be baffle plate for the extension of sieve sheet.
In the work, material enters pulverizing chamber, rotor 2 rotates at a high speed hammer leaf 1 centrifugal development, material is smashed, material flies to sieve sheet 3 under action of centrifugal force, bump once more with the sieve sheet, become granule by bulky grain, material forms along the circulation layer of compass screen surface rotation when doing the high speed centrifugation motion, when material movement arrived the pulverizing chamber bottom, outer field large granular materials was thrown to hammer leaf and is hit end, had strengthened the chance of hitting pulverizing, pulverizer efficient is improved significantly, also is beneficial to the sieve that of small particles material simultaneously.
In addition to the implementation, the utility model can also have other embodiments, is W shape or other shape as damping unit, can be along vertical center line symmetry or asymmetric setting.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all fall into the protection domain of the utility model requirement.
