Description
Technical field
The utility model is mainly concerned with the fiberizer field of paper industry, refers in particular to a kind of enrichment facility that is used for fiberizer.
Background technology
In the prior art, comparatively Xian Jin refining equipment mainly is jordan (comprising cylindrical and conical) and disc mill (double plate and single-deck), and the application of disc mill is more extensive.Disc mill again according to the concentration difference of institute's defibrination material be divided into high dense, in dense and low dense fiberizer, it is generally acknowledged slurry concentration 5% below for low dense, 5～12% is dense in being, is that height is dense more than 12%.In fact the optimum slurry concentration of traditional fiberizer is below 4% because slurry too dense the mill slot that results in blockage easily, just can't work when serious at all.Though high concentration slurry can be saved power consumption, its maximum shortcoming is that to wear into the uniformity of slurry quality very poor, so use can only make low-grade paper the time.It is very low that the high-density paste mill separate unit improves " beating degree ", is not easy to many series connection again and uses, and the most serious problem is that slurry stops up slot.And high-concentration paste mill must be equipped with pulp thickener and feed screw.Though low concentration defibrination defibrination quality is more even, also stronger to the adaptability of fiber species, be convenient to many tandem workings again, its disadvantage is that power consumption is big, grinding machine noise in service is big, makes pulping temperature height.Middle concentrated jordaning is a defibrination process of thinking comparatively desirable at present, but traditional middle-density refiner also needs to be equipped with slurry concentrator and screw feeding equipment, because the pipeline pumping can only could adapt at the slurry concentration below 5%.
The utility model content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provide a kind of simple in structure, easy to operate, volume is little, can reduce the enrichment facility that is used for fiberizer of energy consumption.
In order to solve the problems of the technologies described above, the solution that the utility model proposes is: a kind of enrichment facility that is used for fiberizer, it comprises shell and screen cylinder, the stock inlet place of shell is provided with the stock inlet end cap and is connected with the large end face of conical shell, screen cylinder is loaded in the shell, the inwall of screen cylinder and shell forms an annular compartment, the chamber below has a delivery port, the delivery port place is equipped with a valve, the rear end of shell links to each other with fiberizer, it is characterized in that: be provided with rotary blade near stock inlet end cap one end in the described screen cylinder, an end of close fiberizer is provided with pushing spiral, and described rotary blade and pushing spiral all are installed in the end of fiberizer main shaft.
Described screen cylinder is fixed in the junction of stock inlet end cap and conical shell.
Described screen cylinder is conical.
The stock inlet end cap of described enrichment facility is volute shape.
Compared with prior art, advantage of the present utility model is:
1, the enrichment facility that is used for fiberizer of the present utility model, can directly be installed on the fiberizer, do not need to set up in addition other slurry concentrators, screw conveyor and screw feed equipment, both greatly reduced the loss of energy, reduced floor space again, satisfied the needs of various refining concentrations, and made operation very convenient;
2, the enrichment facility that is used for fiberizer of the present utility model, make slurry rotation at a high speed under the moving blade effect of rotary blade, can make its centrifugal dehydration, but slurry self is flush clean sieve seam also, and the angle that the moving blade of rotary blade and axis form is moving slurry at a high speed to the mill direction in the rotation, the thrust that adds pushing spiral is exerted pressure to the slurry that concentration has increased, slurry is entered in the fiberizer in the rotary grinding disk teeth groove fast, do not cause the obstruction in the enrichment facility, thereby increased the power of slurry motion, improved operating efficiency;
3, the enrichment facility that is used for fiberizer of the present utility model can make slurry select refining concentration arbitrarily by the discharge rate of regulating filtered water before mill, carries out defibrination again after concentrating earlier and accomplishs without any letup, and does not need to join in addition slurry concentrator and screw conveyor;
4, the waste water that is used for the enrichment facility discharge of fiberizer of the present utility model can enter trench or flow into pulper and recycle, and the mill disposed slurry adds the clear water dilution after falling into stock tank in addition, can play the effect of filtering stock like this; Also filtered water can be flowed in the stock tank of mill back, can also play water-saving effect, not only reduce the loss of part fiber fines in the water, also reduce the pollution of environment, this shows that enrichment facility of the present utility model also has the advantage of environmental protection, saving.

The specific embodiment
Below with reference to accompanying drawing the utility model is described in further details.
As depicted in figs. 1 and 2, a kind of enrichment facility that is used for fiberizer of the present utility model, it comprises shell 2 and screen cylinder 3, the stock inlet place of shell 2 is provided with stock inlet end cap 11 and is connected with the large end face of conical shell 2, screen cylinder 3 is loaded in the shell 2, screen cylinder 3 forms an annular compartment 4 with the inwall of shell 2, chamber 4 belows have a delivery port 5, delivery port 5 places are equipped with a valve 6, the rear end of shell 2 links to each other with the fixed millstone of fiberizer 7, be provided with rotary blade 31 near stock inlet end cap 11 1 ends in the screen cylinder 3, the blade of this rotary blade 31 becomes 25 ° of angles with axis; End near fiberizer 7 is provided with pushing spiral 32, and rotary blade 31 and pushing spiral 32 all are installed in the end of fiberizer 7 main shafts.
Enrichment facility of the present utility model is arranged on fiberizer 7 import departments, make the slurry of sending here by stock pump rotate equidirectional entering in the screen cylinder 3 along tangent line and mill, slurry is rotation at a high speed under the moving blade effect of rotary blade 31, thereby causes centrifugal dehydration, but and slurry self flush clean sieve seam.The angle that the moving blade of rotary blade 31 and axis form is moving slurry at a high speed to the mill direction in the rotation.Slurry is through concentrating back concentration increase, and at this moment the movement slows down in annular compartment 4 exerts pressure to slurry by the thrust of pushing spiral 32, and slurry is entered in the rotary grinding disk teeth groove in the fiberizer 7.It is in order to make slurry under the situation that flow velocity and flow all constantly reduce that screen cylinder 3 is designed to taper shape, and its centrifugal force does not reduce too much, by acceleration equation V
2/ R as can be known, after flow velocity reduced, radius can reduce the reduction of centrifugal force along with reducing.Advance to grind concentration and can the valves 6 below screen cylinder 3 regulate the discharge rate of filtered water and control,, in general can in 4～8% scope, regulate to reach required various refining concentration.The filtered water of getting rid of through enrichment facility of the present utility model also has two effects: 1, be can enter trench or flow into pulper to recycle, the mill disposed slurry adds the clear water dilution after falling into stock tank in addition, can play the effect of filtering stock like this; 2, filtered water is flowed in the stock tank of mill back, can play water-saving effect, reduced the loss of part fiber fines in the water simultaneously, also reduced the pollution of environment.This shows that enrichment facility of the present utility model also has the advantage of environmental protection, saving.
