Abstract
The utility model relates to a coal water slurry intense shear stirring tank which is mainly used for mixing and stirring before coal water slurry is burnt in a boiler and a furnace kiln, and mixing and homogenizing when the coal water slurry is prepared. The coal water slurry intense shear stirring tank comprises a tank body (7) and a tank cover (5), wherein the tank body (7) is internally provided with a group of stirrers (8); the lower ends of the stirrers (8) are connected with the bottom of the tank body (7) by a stable bearing (9); the upper ends of the stirrers (8) is connected with a gear speed-reducing motor (1) which is installed on a machine base (3); the machine base (3) is arranged on the top of the tank cover (5); the top of the tank cover (5) is provided with a slurry inlet (12); and the two sides of the lower end of the tank body (7) are respectively provided with a slurry outlet (10) and a drain outlet (11). The intense shear stirring tank combines the tank body and the stirrers into a whole body, and the stirrers are good in the stability, full in stirring and good in shear effect.
Description
(1) technical field
The utility model relates to a kind of water-coal-slurry complete production unit.Especially relate to the strong shear agitation jar of a kind of water-coal-slurry.Be mainly used in shear agitation at the relatively large water-coal-slurry of low-order coal pulping equipment grinding machine outlet viscosity in aqueous coal slurries.
(2) background technology
Before the utility model effect, be used for the agitator tank that water-coal-slurry is sheared at present, be that the side formula stirs and shears, water-coal-slurry shear agitation dead angle is many, and agitator easily produces and rocks, and the agitator less stable stirs insufficiently, and shear effect is undesirable.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of agitator good stability is provided, and stirs fully the efficient strong shear agitation jar of the water-coal-slurry that shear effect is strong.
The purpose of this utility model is achieved in that the strong shear agitation jar of a kind of water-coal-slurry, comprise tank body and cover, be provided with one group of agitator in the tank body, the agitator lower end links to each other with tank base by stable bearing, the agitator upper end links to each other with the gear reduction motor, and the gear reduction motor is installed on the support, and support is installed on the cover top, be provided with pulp inlet at the cover top, be respectively arranged with grout outlet and sewage draining exit in both sides, tank body lower end.
The beneficial effects of the utility model are:
The strong shear agitation jar of the utility model is integrated tank body and agitator, and the agitator good stability stirs fully, and shear effect is good.Shearing the back viscosity in aqueous coal slurries through high strength can obviously reduce, and flowability can satisfy the disposal ability of road, back production link equipment.

(5) specific embodiment
Referring to Fig. 1～2, Fig. 1 is the general structure schematic diagram of the strong shear agitation jar of the utility model water-coal-slurry.Fig. 2 is the A-A cut-away view of Fig. 1.By Fig. 1 and Fig. 2 as can be seen, the strong shear agitation jar of the utility model water-coal-slurry, comprise tank body 7 and cover 5, tank body is cylindrical, cover 5 is installed on the tank body 7 by bolt 6, be provided with one group of agitator 8 in the tank body 7, agitator 8 lower ends link to each other with tank body 7 bottoms by stable bearing 9, agitator 8 upper ends link to each other with gear reduction motor 1, gear reduction motor 1 is installed on the support 3 by bolt 2, support 3 is installed on cover 5 tops by bolt 4, is provided with pulp inlet 12 at cover 5 tops, and both sides, tank body 7 lower end are respectively arranged with grout outlet 10 and sewage draining exit 11.
Operation principle:
During stirring, radially can be divided into turbulent flow, laminar flow and three zones of different (see figure 3)s of viscous flow along agitator.The linear velocity of turbulent area inner fluid equals or near the linear velocity of agitator, thereby turbulent area is effective stirring region.In the turbulent region, the flow velocity of liquid slows down successively along the stirrer diameter direction, and stirring efficiency reduces.Liquid stays cool substantially in the stagnant area.Because agitator rotates, and can produce two kinds of fluidised forms of radial flow and axial flow in the whipping process.Radial flow makes and stirs form turbulent area all around, and axial flow makes agitator have certain flow (circular flow) that pumps.Liquid by turbulent area enters the turbulent area (see figure 4) again through the race way, can guarantee that like this water-coal-slurry is constantly fully stirred and high-strength shearing by turbulent region.
Claims (1)
