The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described in detail:
as Fig. 2, Fig. 3 and shown in Figure 4, vertical and high-speed cement colloid mixer of the present invention comprises agitator 1 and stirring motor 11, stirring motor 11 is vertical type stirring motor, stirring motor 11 is installed on the top of agitator 1, the rotating shaft of stirring motor 11 is connected by axle key 15 with the upper end of the vertical shaft 12 that is placed in agitator 1 interior center, the stage casing of vertical shaft 12 is installed with the first agitator arm 14 by setscrew nut 13, the bottom of vertical shaft 12 is installed with the second agitator arm 29 by key 26 and locking nut 27, the bottom of vertical shaft 12 is positioned at the discharging opening center of agitator 1 bottom, the discharging opening welded and installed of agitator 1 is useful on the spiral case 28 that makes material form eddy motion, the second agitator arm 29 is placed in spiral case 28.
As shown in Figures 2 and 3, the housing lower end of stirring motor 11 is equipped with upper end cover 18, and the lower end of upper end cover 18 is equipped with vertical shaft sleeve 20, and the lower end of vertical shaft sleeve 20 is equipped with bottom end cover 23, the epimere of vertical shaft 12 is placed in vertical shaft sleeve 20, and a plurality of bearings 21 are installed between vertical shaft 12 and vertical shaft sleeve 20; Between vertical shaft sleeve 20 and upper end cover 18, all seal by outside framework oil seal 25 between vertical shaft sleeve 20 and bottom end cover 23.Also show grout outlet 4, ball valve 3, return pipe 2 and agitator mount pad 10 in Fig. 2, also show the outer back-up ring 17 of back-up ring 19, bearing inner shield ring 16, bearing, packing ring 24 in Fig. 3 and be used for adding the grease nipple 22 of butter.
As Fig. 2, Fig. 3 and shown in Figure 4, in the course of work, to be slurries enter from the top of agitator 1 cement colloid, at first stirs through the first agitator arm 14, and in this process, slurries are dispersed and form certain eddy flow, reduce the pressure to agitator 1 bottom; Then slurries are through the second agitator arm 29, because the second agitator arm 29 is little with spiral case 28 gaps of steel casting, so the blade of the second agitator arm 29 can obtain high shear force, slurries are the moment that otch flows into spiral case 28 by the discharging opening of agitator 1, blade drive by the second agitator arm 29 is carried out the reciprocation cycle rotation and produces eddy current, completes slurrying; The slurries that mix are sent by grout outlet 4.
The below analyzes the reason of obvious technical effects of the present invention theoretically:
Within the unit interval, the slurries amount that impeller can affect is more, mixing time is just shorter, under the certain prerequisite in gap between spiral case 28 and the second agitator arm 29, if can increase the contact area of the second agitator arm 29 and slurries, stir so the cement mortar of low water-cement ratio or the difficulty of cement mixing mortar and also will reduce, the possibility that slurry stops up is also less.
According to formula S=a * b, wherein S is the unit contact area, a is that the second agitator arm 29 is positioned at be connected with agitator 1 length of side of incision of spiral case 28, b flows into the length of the slurries of spiral case 28 in the unit interval, namely the flow velocity v of slurries, so just have formula S=a * v, according to this formula, we can draw, and increase the contact area S of unit, and two kinds of purposes of design are just arranged: (1) increases the length of side of incision site the second agitator arm 29; (2) increase the speed of slurries.
So in the present invention, the impeller that the length of side that the second agitator arm 29 is positioned at incision will be longer than traditional high-speed pulping machine is positioned at the length of side of incision; And the rotation of the first agitator arm 14 is just stirred before making slurries inflow spiral case 28, can increase the flow velocity of slurries and the high shear force of mixer, thereby has reached two purposes of design.
As shown in Figure 1, tradition eddy current type pulper has the agitator 1 identical with mixer of the present invention, agitator mount pad 10, ball valve 3, grout outlet 4 and return pipe 2 equally, the stirring motor 6 of different is traditional eddy current type pulper is horizontal machine, its rotating shaft is connected with an end of the connecting axle 5 of horizontal direction, the other end of connecting axle 5 is equipped with agitator arm 8, agitator arm 8 is placed in spiral case 9, and the outside of connecting axle 5 is to connect housing 7.In above-mentioned parts, in order to embody the difference between mixer of the present invention and traditional eddy current type pulper, stirring motor, impeller and spiral case all adopt different marks, agitator 1, agitator mount pad 10, ball valve 3, grout outlet 4 and return pipe 2 are identical, so adopted identical mark.
Comparison diagram 1 and Fig. 2 are as can be known, tradition eddy current type pulper is because agitator 1 is vertical structure, its discharging opening is arranged at the bottom of agitator 1, so agitator arm 8 only has one, be arranged at the discharging opening position of agitator 1, the cement colloid of its top is that the pressure of slurries is very large, if the ratio of mud of slurries low (0.4:1 is following), perhaps the underpower of stirring motor 6, probably stop up; Mixer of the present invention has overcome defects, so solved blockage problem.
