Abstract
The invention discloses an over thick wood chip crusher provided with a machine shell and rotative compression rollers. The over thick wood chip crusher is characterized in that the machine shell is in a fixed box type structure and can be divided into an upper part and a lower part which can be detachable; two ends of the machine shell are provided with short supporting shafts; the machine shell is internally provided with an upper compression roller and a lower compression roller which do opposite retative motion; grooves and convex teeth regularly spread over the surface of each compression roller; the compression rollers are parallel mutually, arranged on the short supporting shafts through a rocker bearing block, and combined into two movable compression rollers which can relatively swing within a certain range; and a hydraulic cylinder is arranged between the two compression rollers. The invention has the advantages of no blockage, low crushed damage rate and favorable recrushing effect.
Description
Technical field
The present invention relates to a kind of blocked up wood chip treating apparatus, belong to the pulping and paper-making special equipment of getting the raw materials ready.
Background technology
Domestic wood pulp factory generally all adopts traditional rechipper, small-sized chipping machine to the processing mode of thick and blocked up wood chip or thick wood chip is refluxed the mode that chipping machine into heavily cuts at present, the effect of old-fashioned desintegrator is thick wood chip to be carried out brute force impact, make sheet be ground into the wood chip shape, the result who handles causes the lumber fibre more than 60% to sustain damage, and valuable timber resources can not be utilized effectively.Sheet is sent into chipping machine heavily to be cut also and can't get a desired effect, do not stress because wooden unit is light, can not be cut again by fly cutter little, and can only be under the powerful percussion of cutterhead and base squeezed broken, to impact wooden unit similar with desintegrator in its effect, and broken rate is also very high.Based on this present situation, the blocked up efficiently wood chip treatment facility of domestic-developed becomes exigence.
Summary of the invention
The object of the present invention is to provide a kind of low, broken respond well blocked up wood chip crushed machine again of obstruction, broken rate that do not have.
The objective of the invention is to be achieved through the following technical solutions: a kind of blocked up wood chip crushed machine, have casing and rotating pressure roller, it is characterized in that: casing is fixing case structure, be divided into detachable separation on, following two parts, there is the supporting minor axis at the casing two ends, be furnished with last pressure roller and the lower compression roller of doing relative gyration in the casing, be covered with groove and double wedge on the roll surface of every pressure roller regularly, be parallel to each other between pressure roller and the pressure roller, be installed on the supporting minor axis by the rocker arm shaft bearing, be combined into two movable platen that can swing relatively within the specific limits, between two pressure rollers, hydraulic cylinder be housed.
Described two pressure roller diameters are identical, rotating speed equates, turn to relative.
Described roll surface double wedge is projective table type, and is assembled by gear ring, and gear ring adopts high-abrasive material to make.
The present invention compares with common desintegrator, and structural principle is different fully, and the broken again effect of wood chip relies on the extruding force between two pressure rollers to realize, thereby can smash with the thick thick even pressure break of wood chip rather than with wood chip, and stable and reliable operation does not have impact shock; Hydraulic system can prevent that changes in flow rate from causing machine to stop up according to the automatic gap of adjusting between two rollers of wood chip throughput size; The rotating speed of two pressure roller shaft is stepless adjustable, and rotating speed can be regulated arbitrarily according to the output size, and it is extremely convenient to manipulate.
The present invention have do not have to stop up, broken rate is low, broken respond well advantage again.

The specific embodiment
Further illustrate content of the present invention below in conjunction with accompanying drawing and instantiation, but these embodiment do not limit protection scope of the present invention.
As Fig. 1, Fig. 2, shown in Figure 3, casing 9 of the present invention is fixing case structure, the upper and lower two parts that are divided into detachable separation, there is supporting minor axis 6,8 at the casing two ends, be furnished with in the casing that the last pressure roller 3 of doing relative gyration is identical with lower compression roller 4, two pressure roller diameters, rotating speed equates, turn to relative, be covered with groove and double wedge on the roll surface of every pressure roller regularly, the roll surface double wedge is projective table type, and is assembled by gear ring, and gear ring adopts high-abrasive material to make; Be parallel to each other between pressure roller and the pressure roller, be installed on the supporting minor axis, be combined into two movable platen that can swing relatively within the specific limits, two-way hydraulic cylinder 14 is housed between two pressure rollers by rocker arm shaft bearing 15,16.Every transmission case drives 1 pressure roller revolution by universal joint.The two ends hydraulic cylinder is done the swing gap between bi-directional expansion motion control two pressure rollers and extruding force to wood chip is provided: when the two-way hydraulic cylinder forward shrank, the rocking arm that furthers reduced two nip; When the hydraulic cylinder negative drawing, push rocking arm open, two roller gaps are increased.
During work: two pressure rollers turn round towards relative direction with certain rotating speed, the wood chip that need crush falls into the gap that two pressure rollers constitute from charging aperture, under the drive of roll surface, move downward, when between two roller contact-making surfaces, passing through, be subjected to two roller powerful extrusion force and by pressure break, become accepted chips, discharge from discharging opening at last.Because the gap and the extruding force size of two pressure rollers are to be controlled automatically by hydraulic system, the extruding force size of its generation generally is constant, thereby can realize the self-regulating purpose in two roller gaps.
Automatically regulate the gap and be achieved in that the extruding force that produces can increase when the wood amount by the gap increases between two rollers, the hydraulic cylinder stretching is forced outwardly gap between two rollers and pushes away; When the wood amount by the gap reduced, the extruding force that is produced reduced, and hydraulic cylinder shrinks, and the gap between two rollers is dwindled.Therefore, the no matter wood amount variation of how fluctuating, the extruding force that can keep relative stability makes wood chip be subjected to extruding uniformly and by pressure break, obtains broken more very reliably effect.When running into hard objects such as ironware stone, can produce powerful extrusion force hydraulic cylinder is drawn back, not crushed and play the effect of protection machine from face protection roll surface.
