Detailed description of the invention
With reference to accompanying drawing 1 is described, be a kind of cement grout agitating kettle of horizontal type structure, the namely horizontally disposed agitated kettle of shaft, comprising:
Agitated kettle body 3, is provided with cement charging aperture 2, water inlet 1, and discharging opening 11;
Shaft 7, main body is positioned at described agitated kettle body, and shaft coupling end extends described agitated kettle body via shaft seal; And
Vane group, containing along described shaft be axially disposed within be positioned at agitated kettle body described shaft on and be configured to two kinds of contrary blades of rotation direction.
Vane group according to said structure can be applied in the cement grout agitating kettle of vertical structure equally, and the change of vertical state can't affect the change of paddle liquid turbulent state.
But, due in cold in place recycling technique, agitated kettle needs device on a mobile platform, and therefore, preferably selecting is horizontal type structure as shown in Figure 1, to lower the center of gravity and the connection of relevant feedstocks mouth and discharging opening configures.
About the setting of charging aperture and discharging opening, show that this programme Raw has two kinds, one is water, another kind is cement, with a mouth in theory, discharging opening is also feasible with a mouth under many circumstances even, especially for the simple open type agitated kettle of structure, charging aperture only has one, other discharging opening extremely individual and the not same mouth of charging aperture, therefore, each mouth comprising cement charging aperture 2, water inlet 1 and discharging opening 11 configures relatively more flexible in current mixing plant, and correspondence is as shown in Figure 1 upper and lower, front and back configuration structure.
Adopt single-shaft configuration in this programme, namely only have a shaft, but other also can be adopted to configure, as cross-compound arrangement, two axle steers are identical as required, form the head-on collision of stirring stream, to meet better mixing effect.
See group blade of in the middle part of Figure of description 1, two kinds of blades that rotation direction is contrary, configure in pairs and form multiple blade unit, under working rotation condition at described shaft 7, two blades in each blade unit push the material stirred to both centers, be stir the eddy current that produces to produce to liquidate and clash in other words, do not need that the control device of shaft is configured to rotating and control, structure is simpler.
Through checking, a blade unit also can meet good mixing effect, and because two blades in a blade unit are to centre propelling movement stirring liquid, liquid has mobility again, the disturbance that additional flow produces can be produced, can produce compared to the better mixing effect of convention stir structure.
In order to increase the disturbance effect because additional flow produces, described blade unit has multiple, and the effect of the stirring of multiple blade unit simultaneously itself is also better than one.
But blade unit increases not only can increase manufacturing cost, and the moment of torsion required for stirring also can improve greatly, causes too much energy ezpenditure.Balance mixing effect and manufacturing cost and energy consumption, described blade unit is preferably two.
When described agitated kettle body adopts horizontal type structure, for being conducive to pipe arrangement, correspondingly, described shaft level is assemblied on described agitated kettle body, and the top, one end of agitated kettle body is arranged at the described cement charging aperture 2 of the axis of shaft and water inlet 1, discharging opening is then arranged on the bottom of the agitated kettle body other end, and this other end is shaft shaft coupling end.Meanwhile, the discharging opening of said structure and charging aperture configuration mode, be also conducive to arranging on a mobile platform.
Preferably, see the left end of Figure of description 1, described vane group also comprises the helical blade being positioned at described cement charging aperture side be arranged on described shaft, screw propulsion blade as illustrated in the drawing, form the form of structure being similar to conveying worm, push material to be mixed with the leaf area becoming rotation direction contrary along shaft axial arrangement.
On the other hand, the existence of helical blade can carry out initial mixing to water and cement.Moreover because slurry fluidity is comparatively strong, reflux also can produce head-on collision with conveying, can produce better mixing effect.
Further, preferably structure is described agitated kettle body 3 is Horizontal cylinder shape structure, and described shaft and agitated kettle body coaxial line configure; Correspondingly, described cement charging aperture is arranged on the upside on agitated kettle body top, and water inlet is arranged on agitated kettle end cap top, facilitates material loading and discharging, and without the such cleaning dead angle of square agitated kettle, cleaning is also than being easier to.
In order to more be conducive to stirring and discharging, as shown in Figure 1, the shaft coupling end being positioned at shaft at described agitated kettle body 3 is provided with discharge zone, correspondingly, the region at vane group place is stirring area, be connected to the semicircular movable bin gate 12 of agitated kettle body in one under stirring, form the lower partition of stirring area and discharge zone.Thus, when agitated kettle works, semicircular movable bin gate 12 is in the vertical state shown in Fig. 1, water and cement powder add in cylindrical shell from left side, stirring area, middle part is entered through helical blade, for ensureing that water and dry powder fully stir, movable material goalkeeper compound gear makes it directly not flow out from discharging opening in left side.And then adding along with material, the liquid level in agitated kettle can rise to the upper edge of movable bin gate gradually, and the stirring action of blade can perform to maximum, and mixing effect is best, and water and cement can fully mix, and ensure that good mixing effect.Along with water and cement material level raise gradually on the left of bin gate, the cement slurry material be finally stirred can flow into discharging opening from the upper of semicircle bin gate along overflowing, and completes the overall process of stirring.Semicircle bin gate can be rotated counterclockwise in the condition shown in figure 1 during off working state, such stirring region is directly communicated with discharging opening, and the water being convenient to clear up mixing drum and mixing arm flows out.
Preferably, see Figure of description 1, on the upside of described discharge zone, be provided with flash mouth 8, condition monitoring can be carried out to material, especially the state of material overfill.
About the manipulation of movable bin gate, adopt mechanically operated mode, see Figure of description 2, the content affecting activity bin gate mounting structure and express is omitted in figure, the structure operated for described movable bin gate 12 is, the string (movable bin gate geometry) of described movable bin gate 12 is arranged perpendicular to shaft in horizontal plane, and is provided with in being articulated with the hinge 16 on described agitated kettle body 3 corresponding to the movable bin gate two ends of this string, makes movable bin gate form rocker; One hinge extends agitated kettle body and chain is connected to one handle 15, just can be carried out the manipulation of movable bin gate by handle very easily.
Further, conveniently clear up, see the right-hand member of Figure of description 1, the shaft 7 being positioned at described discharge zone is connected with the material scraping plate 10 with discharge zone inner circumferential wall matched in clearance by the radial connector extended.In whipping process, material scraping plate also can carry out scraper, prevents cement solidification.
