Description
Technical field
The invention belongs to field of papermaking, relate to pulp and paper industry machinery equipment, especially a kind of biconial high-density paste mill.
Background technology
High consistency refining due to water consumption few, yield is high, and energy consumption is lower, is used widely in pulping process.At present, conventional defibrination machinery can be divided into disc, taper shape (actual is the taper type not having drift angle) and cylindrical pulping machine according to the shape of its rotor (rotating disk).Disc pulping machine (also known as disc mill) is mainly divided into single-deck grinding machine, double disc refiner and triple disc refiner machine, conical disc mill pulp grinder is divided into single taper thread grinding pulp grinder and third hand tap fiberizer, and tapering has Small Taper (cone angle≤40 °) and steep-taper (cone angle > 40 °) two classes.Because disc mill and conical refiner have the common feature that low speed endfeed, speed end discharging and refining plate interval easily adjust, so use comparatively extensive.At present, high-density paste mill is single-deck grinding machine and conical refiner mostly, and single disc refiner machine axial dimension is little, adopts and easily to overhaul opening structure and to change abrasive disc, and use the most extensive, but single disc refiner machine axial force is large, energy consumption is higher; Conical refiner designs owing to adopting small-angle more, although refining energy consumption is less, axial force is large, and repair demolition is more bothersome.
Research shows: when dissimilar fiberizer effective defibrination area is equal with rotating speed, defibrination efficiency is equal.When effective defibrination area equation, conical refiner rotor size is minimum.Runner size reduces, and can subtract trochantinian quality and rotary inertia, and mean the no-load power consumption reducing fiberizer, obviously can reduce refining energy consumption, this point is confirmed aborning.Under the prerequisite ensureing defibrination quality and efficiency, reduce fiberizer energy consumption, be the target of pulping and paper-making industry unremitting pursue always.
In addition, by analysis, the invention of some Novel tapered high-density paste mill also exists some problems, dense mill (US5383608,1995-06-24) as high in the biconial with double helix charging is owing to adopting shaft type, Double-helix propeller charging, complex structure, maintenance is inconvenient; And for example high dense Triple-Cone Double-Flow Conical Refiner (ZL200820029691.8,2009-6-24) Three-cone direction is identical, and axial force is very large, and installation and maintenance are inconvenient.Due to these reasons, the application of these inventions is restricted.

The present embodiment devises the rotor adjusting pad of one group of different-thickness, and when abrasive disc uses a period of time that wearing and tearing occur, namely the thickness of reduction two rotor adjusting pads can reduce the axial distance between rotor two conical surface, reaches the object reducing refining plate interval.Because fragmentation mainly plays in cylindrical mill district, therefore do not consider the gap adjustment problem in this mill district.
Fig. 5 of the present embodiment is the secondary radial opening procedure signal picture group of embodiment of the present invention mill room.
Mill chamber opening process is that radial direction opens mill chamber cap (as Fig. 5 (a1, b1)) for the first time, and dismounting cone cap, left cone rotor and rotor terminal pad, can change left and right rotor adjusting pad, realizes biconial mill district refining plate interval and adjusts.Consider the convenience of concrete operations, do not dismantle rotor terminal pad, only change left rotor adjusting pad, also can reach the object of adjustment biconial mill district refining plate interval.Changing the abrasive disc of wearing and tearing as needed, needing to continue to remove feed auger (whole feed system moves to right (as shown in Figure 2) by demounting bolt group) and mill room supporting pad (as Fig. 5 (a2, b2)); Then can second time radial direction open in the middle part of mill room (as Fig. 5 (a3, b3)).Now, all regions of biconical rotor and biconial stator are all opened wide, and are convenient to change and overhaul all abrasive discs.
The operation principle of the present embodiment is:
The feed pipe of high consistency stock under the effect of feed auger in the middle part of mill room enters in the middle part of the defibrination district of rotor and stator composition, first pass through broken in cylindrical defibrination district, then enter taper defibrination district, both sides under pressure respectively to carry out roughly grinding and refining, after throwing away from the large end in taper defibrination district, flow out mill room from both sides grout outlet under gravity.
The mill indoor of the present embodiment are respectively arranged with three defibrination sections, i.e. the conical defibrination section of two specular and the middle cylindrical defibrination section be connected, and this design can make the axial force of rotor and stator cancel out each other; The effect of cylindrical defibrination section groove mainly plays fragmentation, and the groove of the conical defibrination section in both sides mainly plays corase grind and fine grinding effect.
The abrasive disc of the present embodiment can adopt monoblock type taper stator, rotor abrasive disc and cylinder shape stator, rotor abrasive disc, abrasive disc sunk screw is fastened on stator seat or rotator seat, when biconial high-density paste mill diameter is larger, for the ease of manufacturing the fan-shaped or rectangle abrasive disc processed and can measure-alike, surperficial groove is divided into identical unitary stator, rotor abrasive disc.
The adjustment mode of refining plate interval of the present invention:
Biconical rotor is designed to separate type, namely two ends frustum and the face of cylinder all can be separated, at its mating surface, the identical ring-shaped rotor adjusting pad of two thickness is installed, when the axial relative distance of biconial stator is fixed, change the thickness of rotor adjusting pad, the refining plate interval between two cone rotors and taper stator can be changed.In addition, the forward and backward two bearings group of rotor main shaft all adopts cylinder roller bearing, and when between two cone rotors and stator, refining plate interval has a difference, the axial force of generation makes biconical rotor move left and right vertically, automatically can adjust and make both sides refining plate interval equal.Therefore, consider that biconical rotor and main shaft axially can move freely the convenience with concrete operations, only change the ring-shaped rotor adjusting pad in left side, also can reach the object of adjustment both sides cone rotor and stator refining plate interval.
