Abstract

The utility model discloses a bamboo shredder, which belongs to an improvement of a hammer type shredder, and can be used for shredding bamboos and be used as pulping stock for paper mills. The utility model is composed of a rotor section (I), a shredding sieve section (II) and a frame rack section (III). The main working section of the bamboo shredder is the steplike gap arranged between a ram and a shredding toothed rack in the direction of the self feeding port. Because the utility model can overcome the disadvantage that the bamboo can only be cut into lumps instead of filaments, the cooking time of the bamboo can be shortened from 6 to 7 hours/ spherical tank to 2 to 3 hours/ spherical tank.

Description

Bamboo crusher

A kind of bamboo shredder belongs to the improvement of hammer mill, is used to tear up bamboo, and this machine is specially adapted to the paper mill as the slurrying usefulness of getting the raw materials ready.

At present, the hammer mill that use in the mine can only be used for broken hard or medium-hard rock (ore deposit) stone, and the bamboo cutter of the present usefulness in paper mill can only cut off bamboo frustillatum, causes alkali lye to be difficult to immerse, digestion time need reach 6～7 hours/every spherical tank, can't carry out and work continuously.

Task of the present invention provides a kind of machine that tears up bamboo, the bamboo that this machine can prescind into 2～3 meters long bamboos or bamboo cutter fritter is torn and is cut into thin bamboo silk, this bamboo silk easily makes alkali lye immerse in pulping process, infiltration is even, thereby makes digestion time shorten to 2～3 hours/every spherical tank; If again behind depithing machine, the practicable continuously cooking of companys of entering steaming device, but and energy savings, dosage, increase output and reduce production costs.

The utility model tears screen sections (II) by rotor portion (I), and rack section (III) is formed.Rotor portion (I) is made up of bearing pin (1) and tup (2) etc., and tup is arranged along the rotor axis direction, removes between the tup (2), leaves outside 4～9 millimeters gaps between tup (2) and the frame (III), and remainder is all arranged full tup.This tup is decided by its tear(ing) strength along row's number of rotor axis direction, if bamboo requires to tear carefully, tup is just many at epitrochanterian row's number, otherwise just few.The tup number of permutations of the present utility model is three rows.

Tear screen sections (II) and be divided into two sections, one section of adjacent charging aperture is for tearing up tooth bar (5), its arc length in screen frame (unit) (3) is upward shared is 740 millimeters, tearing up tooth bar is stairstepping along the rotor normal direction and closely arranges on screen frame (unit), from the charging aperture direction, tear up the gap on tooth bar and tup top and reduce to 5 millimeters gradually from 15 millimeters.The quantity of tearing up tooth bar can require to adjust according to tearing up, and when the degree of tearing up is not enough, can increase tooth bar, tears up excessively, then reduces tooth bar.It is 23 that the present invention tears up the tooth bar number.

Another section of tearing screen sections is for grating (4), its on screen frame (unit) shared in arc length be 447 millimeters, the grating number can subtract according to the increase and decrease of tearing up tooth bar quantity and increase.Grating number of the present invention is 6.Arc length is 22～24 millimeters in the sieve seam between grating and grating, and the thin bamboo silk after tearing up can be discharged from the sieve seam.Tup and the gap of tearing up between tooth bar are the groundwork part of bamboo shredder.

Accompanying drawing is an embodiment of the present utility model.

Fig. 1 is the front view of bamboo shredder.

Fig. 2 is the side view of bamboo shredder.

The course of work of the present utility model is: bamboo is entered in the shredder by charging aperture (6), be subjected to the impact of the tup (2) of the widely different commentaries on classics of 50～56 meter per second high speeds immediately, and be subjected to the effect of certain pressure, shearing force, bending stress in tooth bar (5) gap from big to small and cut off, tear up with tearing up on the tup top, bamboo silk after tearing up is discharged from the sieve seam, the bamboo that does not have to discharge continues to cut off, tear up under tup and the effect of tearing up tooth bar, go round and begin again, reach the purpose of tearing up.

Claims

1, a kind of bamboo shredder, by rotor portion (I), tear screen sections (II), rack section (III) is formed, it is characterized in that: remove between the tup (2), leave outside 4～9 millimeters gaps between tup (2) and the frame (III), the rotor axis direction should all be arranged full tup, tears up tooth bar (5) and is stairstepping along normal direction on screen frame (unit) and closely arranges.

2, according to the bamboo shredder of claim 1, it is characterized in that:, tear up tooth bar (5) and on screen frame (unit), in the shared arc length, reduce to 5 millimeters gradually from 15 millimeters with gap, tup top from the charging aperture direction.
