The invention is provided with two high-efficiency crushing areas A and B, and an ultra-high efficiency crushing area C; when the hammer head of the hammer slices axially staggered with the dual-rotor assembly has partial superposition, the highest relative linear speed between material and the hammer slices can reach 2 times of the designed hammer slice speed, thus greatly improving crushing efficiency.

Description

Birotor beater disintegrating machine
Technical field
The present invention relates to a kind of beater disintegrating machine, especially a kind of charging aperture, support, casing and rotor assembly that comprises band guide guider, casing is positioned on the support, and charging aperture is positioned at the beater disintegrating machine on the casing.
Background technology
No matter the existing beater disintegrating machine in market is homemade or import mostly be the single rotor structure.In order to improve the crush efficiency of pulverizer, normally adopt to increase the linear velocity that root diameter improves hammer leaf.Present single rotor beater disintegrating machine, because be subjected to the restriction of the structural design and the strength of materials, the maximum linear velocity of its hammer leaf has reached 100 metre per second (m/s)s at present, the safety coefficient of its material is very low, want further to improve the linear velocity of hammer leaf, abnormally dangerous.Therefore, the operating efficiency of single rotor pulverizer has not had good way further to improve.For solving foregoing problems, Chinese patent literature CN2033706U discloses a kind of feed grain pulverizer, it is by two rotors of identical in structure, upper and lower casing, feeding hopper and motor are formed, two rotors housing both sides of packing into side by side, flabellum and main shaft symmetry are welded on the collar bush vertically, and concentric with it; Bearing pin vertically, be distributed on the concentric circumference of main shaft on, hammer leaf is by dress between spacer on it; In the sieve sheet is packed the sieve holder of upper and lower casing inboard into along circumference; Stationary knife is packed on the holder of upper and lower casing inboard, and main shaft links with key and its axle sleeve; Feeding hopper links to each other with body with pole by hinge respectively; This birotor pulverizer is owing to adopted birotor, and hammer leaf cooperates and big cornerite sieve sheet with stationary knife, and the version of negative pressure suction-type classification malleation discharge improves its crush efficiency, and energy consumption descends.But, this birotor pulverizer, it can not improve the relative linear velocity of hammer leaf and material, so the raising of this pulverizer crush efficiency is very limited.
Summary of the invention
The purpose of this invention is to provide the higher birotor beater disintegrating machine of a kind of crush efficiency.
Technical scheme of the present invention is: design a kind of birotor beater disintegrating machine, comprise charging aperture, support, casing and rotor assembly, casing is positioned on the support, and charging aperture is positioned on the casing, is provided with the rotor assembly that two levels are parallel to each other in casing; The hammer leaf of described two rotor assemblies axially shifts to install.
The tup end of the described hammer leaf that axially shifts to install overlaps, promptly the tup end face of the hammer leaf of two rotor assemblies to the axle center apart from sum greater than the distance between the axle center of diaxon.
Gapped between the tup end of the described hammer leaf that axially shifts to install, promptly the tup end face of the hammer leaf of two rotor assemblies to the axle center apart from sum less than the distance between the axle center of diaxon.
Also include the guide guider, described guide guider is positioned on the charging aperture.
The cross section of described guide guider is an isosceles triangle, and its leg-of-mutton bottom surface is the backgauge face, and two inclined-planes are the guide face; The drift angle of guide guider by the rotating shaft activity orientation on described charging aperture.
On the inner face of described shell, also be provided with the sieve sheet.
The present invention is the structures that axially shift to install owing to having adopted the hammer leaf of described two rotor assemblies, the birotor beater disintegrating machine of design like this, it has two efficient district A, B of pulverizing, pulverize district C with a ultra high efficiency, in two intervals of A, B, the relative velocity of material and hammer leaf is exactly the design hammer leaf speed of pulverizer; When the tup end of the hammer leaf that axially shifts to install of birotor assembly overlapped, the relative linear velocity of its material and hammer leaf is the highest can to reach 2 times of design hammer leaf speed of pulverizer, so it can greatly improve crush efficiency in the C district.In addition, with the cross section of guide guider is isosceles triangle, its leg-of-mutton bottom surface is the backgauge face, two inclined-planes are guide face structure, the main effect of its backgauge face is in order to destroy pulverizing chamber inwall material formed material ring under the rotor effect, prevent that material and hammer leaf from producing move toward one another, improve strike effect, increased an efficient district of hitting.
