Abstract
The utility model discloses a hammer-sheet grinder which belongs to the field of feed machinery. The hammer-sheet grinder comprises a grinding chamber formed by the enclosing of end plates and side plates; an upper casing is connected above the grinding chamber; the upper part of the upper casing is connected a feeder; a rotor is arranged in the grinding chamber and is mounted on a spindle horizontally passing through the two end plates; the two ends of the spindle are supported on a frame through a bearing block; screen pieces full of meshes semi-surrounding the rotor from the bottom and two sides of the grinding chamber are arranged on the periphery of the rotor; a discharge port is arranged below the grinding chamber; the discharge port and the grinding chamber are separated by screen pieces; and air feed openings are formed on the circumference of the upper casing. Supplementary air blows inwards in the radial direction from the peripheral region of a circulation layer; large particles in the peripheral region of the circulation layer are blown into a material layer, and damage the circulation layer; the large particles blown into the inner layer crash into hammer sheets on the rotor again and are ground; and then air flow continuously flows outwards in the radial direction and carries small particles ground to the screen pieces for being filtered. The grinder with high production efficiency and lower energy consumption has good effect of damaging the circulation layer.
Description
Technical field
The utility model relates to a kind of disintegrating apparatus of feed processing usefulness, particularly a kind of beater disintegrating machine.
Background technology
At present, grain and feed are pulverized the main beater disintegrating machine that adopts of processing, hammer crusher comprises the pulverizing chamber that is formed by end plate and side plate closure, upper casing is connected the pulverizing chamber top, its top links to each other with feeder, be provided with rotor in the pulverizing chamber, rotor is installed in a level and passes on the main shaft of two end plates, the main shaft two ends are supported on the frame by bearing block, hammer frame plate is installed on the main shaft at regular intervals, be evenly distributed with a plurality of pin shaft holes on the hammer frame plate, bearing pin is installed in the pin shaft hole, and hammer leaf is installed on the bearing pin and by spacer and is spaced from each other, and the rotor periphery is provided with from the sieve sheet of the densely covered mesh of pulverizing chamber bottom and both sides semi-surrounding rotor, the pulverizing chamber below is provided with discharging opening, and is isolated by the sieve sheet between discharging opening and the pulverizing chamber.
During this pulverizer work, discharging opening is connected the material aspirator, and material enters pulverizing chamber by feeder and stock guide, simultaneously, external power source with epitrochanterian hammer leaf centrifugal development, is smashed material by hammer leaf through the rotation of main shaft drives rotor high-speed, material flies to the sieve sheet under centrifugal force and air-flow effect, 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 is when doing the high speed centrifugation motion; can form a circulation layer along the compass screen surface rotation; under action of centrifugal force; bulky grain in the material accumulates in the periphery of circulation layer; and short grained material accumulates in the interior week of circulation layer; oarse-grained material stops up mesh and stops that short grained material passes the sieve sheet, and pulverizer efficient is reduced.
For destroying the material circulation layer, CN1669658A has announced a kind of pulverizer, and the cylindrical orthographic projection scope that is positioned at rotor on the pulverizing chamber end plate is provided with wind-supplying mouth.CN201098625Y has also announced a kind of axial type hammer blade grinder, in the main shaft outside and pin shaft hole one inner air channel is set between the revolution inside circumference of main shaft, described inner air channel comprises between the adjacent hammer frame plate sleeve pipe with the coaxial setting of main shaft, the hammer frame plate of sleeve pipe inboard is provided with the air intake passage that is connected with air inlet on the end plate of pulverizing chamber two ends, and described sleeve pipe circumferential surface is provided with some air outlets.These two kinds of pulverizers, all be from axial interior all wind of mending to circulation layer, just rough air is earlier from axially entering the interior week of circulation layer, it is little to the circulation layer influence to mend general mood stream in this process, air-flow flows radially outward then, because material also is radially outward to move under centrifugal action, and both direction unanimities, so air-flow is relatively poor to the disturbance effect of material, and is little to the destruction of circulation layer.
Also have a kind of hammer crusher on the market, be provided with wind-supplying mouth, mend wind and material and enter pulverizer simultaneously in a side of feeder, material produces obstruction to mending wind, influence the required air quantity of pulverizer, made the screen capacity that of powder be affected, same relatively poor to the disturbance effect of circulation layer.
The utility model content
The utility model provides a kind of hammer crusher, mends the problem of wind to circulation layer disturbance weak effect in the prior art to solve, and makes circulation layer be damaged, and improves the operating efficiency of pulverizer.
For solving above technical problem, the technical solution of the utility model is, a kind of hammer crusher is provided, comprise the pulverizing chamber that forms by end plate and side plate closure, upper casing is connected the pulverizing chamber top, its top links to each other with feeder, be provided with rotor in the pulverizing chamber, rotor is installed in a level and passes on the main shaft of two end plates, the main shaft two ends are supported on the frame by bearing block, and the rotor periphery is provided with from the sieve sheet of the densely covered mesh of pulverizing chamber bottom and both sides semi-surrounding rotor, and the pulverizing chamber below is provided with discharging opening, isolated by the sieve sheet between discharging opening and the pulverizing chamber, the circumference of upper casing is provided with wind-supplying mouth.
As improvement of the present utility model, the length of wind-supplying mouth equates with effective active length of rotor.
Wind-supplying mouth is arranged on the circumference of upper casing, mending wind at first inwardly blows from the outer periphery of circulation layer, the bulky grain that will be positioned at the circulation layer periphery blows to bed of material inside, destroyed the material circulation layer, the bulky grain and the epitrochanterian hammer leaf that enter internal layer bump once more, thereby obtain pulverizing, simultaneously under the effect of aspirator, air-flow radially outward continues to flow, and the granule band after pulverizing is discharged to the sieve sheet; Owing to be independent air intake, intake can be guaranteed, and goes out screen capacity and is improved, and has saved energy consumption.And the length of wind-supplying mouth equates with effective active length of rotor, can make whole circulation layer obtain destroying.
