Summary of the invention
The invention provides a kind of devices and methods therefor for the whole grain of the disconnected bar of bar shaped solid particle, it can by the bar shaped solid particle of different length efficiently the whole grain of disconnected bar be that shorter, length is compared with the particle of homogeneous, to overcome the deficiencies in the prior art.
The technical solution adopted in the present invention is:
For a device for the whole grain of the disconnected bar of bar shaped solid particle, this device comprises feed system, disconnected bar system, product particle gathering system and dust catching system.

For a method for the whole grain of the disconnected bar of bar shaped solid particle, step is as follows:
(1) the bar shaped solid particle of whole bar that will break grain is sent into the charging/air inlet of feed bin, according to the rotating speed of the length of the bar shaped solid particle of the whole grain of the bar that will break or mechanical strength adjusting adjustable speed motor, open valve, the suction that air produces by rotary blade is entered the charging/air inlet of disconnected bar device by the charging/air inlet of feed bin, the solid particle of bar shaped is simultaneously entered the charging/air inlet of disconnected bar device under the rolling action of self gravitation and air-flow by the charging/air inlet of feed bin;
(2) under the effect of rotary blade, bar shaped solid particle does centrifugal motion and gets rid of to annular impact walls with a certain speed, near annular impact walls, bar shaped solid particle and the collision of annular impact walls or collision mutually, solid particle after collision leaves annular impact walls under air-flow carries, and enters gas solid separation chamber;
(3) solid particle with dusty gas when gas solid separation chamber separates, utilize vibrating machine screening mode that the solid particle of different length is separated successively, the particle that wherein rectangular particle collector is collected is sent into feed system again as recycle stock, the particle that qualified products particle collector is collected is as product, and the particle that particle collector in small, broken bits is collected is for the raw material as preparation bar shaped solid particle;
(4) the isolated dusty gas in gas solid separation chamber enters dust catching system, emptying after filter bag dedusting.
The principle that the present invention realizes the whole grain of selective disconnected bar is: bar shaped solid particle enters after rotary blade, enter radial mode blade or backward type blade passage, change into along the relative motion of radial mode blade or backward type blade, and collide or collide with the solid particle that the rear bounce-back of collision is returned with a certain speed and annular impact walls, all bar shaped particles all have similar movement locus, when bar shaped solid particle and annular impact walls are collided or mutually collide, it is mainly a contact, the spot speed of the point of impingement sharply changes, and under effect of inertia, still keep original motion state away from the part of the point of impingement in bar shaped solid particle, taking the point of impingement as fulcrum, in bar shaped solid particle, produce the moment that is parallel to its motion and collision course, wherein to cause rectangular particle to be fractured into the main cause of billet particle perpendicular to the axial moment of components of bar shaped solid particle, be referred to as breaking moment, bar shaped solid particle is longer, quality is larger, inertia is larger, the reaction force producing is larger, breaking moment is larger, more disconnected bar, and bar shaped solid particle is shorter, quality is less, inertia is less, while bumping, the original motion state of whole bar shaped solid particle easily changes, breaking moment is little, not easily broken, thereby reach the object of the whole grain of selective disconnected bar, owing to changing the rotating speed of adjustable speed motor, can change speed and inertia force that bar shaped particle leaves rotary blade, so for the bar shaped particle for the treatment of whole grain with different length and mechanical strength, can be by adjusting the rotating speed of adjustable speed motor, increase or subtract short grained impact velocity and inertia force, obtain the whole grain of best disconnected bar effect.
The invention has the beneficial effects as follows: (1) disconnected bar device utilizes bar shaped solid particle length difference, the inertia difference having, stressed and breaking moment when collision different by the bar shaped solid particle of different length optionally the whole grain of disconnected bar be that shorter, length is compared with the particle of homogeneous; (2) disconnected bar device utilizes rotary blade to make in an orderly manner continuously bar shaped solid particle accelerate, collide disconnected bar, discharging, remains the disconnected bar efficiency of efficient stable; (3) disconnected bar device integrates rotary blade, annular impact walls, utilize centrifugal force to accelerate, with utilize gravity make bar shaped solid particle accelerate rotating drum type pelleter compared with, this device volume and floor space significantly reduce, and have greatly saved material, fittings cost and manufacturing expense; (4) motor speed is adjustable, and then the linear velocity that rotary blade is rotated is adjustable, can meet the whole grain of disconnected bar of the bar shaped solid particle of different size, different fracture strengths; (5) emptying after the isolated dusty gas in gas solid separation chamber is purified by filter bag, has avoided dusty gas to outside environment.
