The rotatable scraped wall hydraulic vacuum disperser of the present invention is further described below with reference to the examples:
the invention can turn around and scrape the wall type hydraulic vacuum dispenser, including lifting unit, stander gyration assembly, main drive assembly, secondary drive assembly, stir and disperse the assembly, vacuum assembly and switch box 18, every subassembly compact structure, function coordinate; the stirring dispersion assembly and the main transmission assembly are core components of the whole device.
Firstly, arouse the PLC controller through touch panel, start big speed adjusting motor 17 among the main drive assembly, big speed adjusting motor 17 drives big band pulley 21, big band pulley 21 passes through belt 23 drive little band pulley 22, the (mixing) shaft 14 that little band pulley 22 drive is connected with it, thereby realize the rotation of dispersion impeller 12, because dispersion impeller blade 13 all inclines to be arranged, it is tangent with the outer fringe of dispersion impeller 12, and the opposite direction of bending of two adjacent dispersion impeller blades 13, in the course of the work, can increase the area of contact of dispersion impeller 12 and material, material in the dispersion impeller that more can be abundant minces.
And then, the PLC is excited through the touch panel, the small speed regulating motor 15 in the secondary transmission assembly is started, the small speed regulating motor 15 drives the bevel gear 24, the bevel gear 24 drives the bevel gear end 111 of the scraper 11, and the bevel gear end 111 drives the blade end 112 to rotate through the hollow shaft 113 of the scraper 11.
Because the power of the large speed regulating motor 17 is 22kw, the speed regulating range which can be realized by the stirring shaft 14 controlled by the large speed regulating motor 17 is 0-1450 rpm; the power of the small speed regulating motor 15 is 11kw, and the small speed regulating motor 15 can realize the speed regulating range of 0-65rpm of the blade end 112 of the scraper 11; because the difference of big speed governing motor 17 and little speed governing motor 15 power, thereby realize the differential rotation of dispersion impeller 12 and scraper blade 11 blade end 112, dispersion impeller 12 rotates at a high speed and plays the effect of rapid mixing dispersion material, the low-speed rotation of scraper blade 11 blade end 112 plays the effect of scraping the material of adhesion on agitator 10 inner wall and preventing material deposit, the differential rotation through stirring dispersion subassembly can effectively improve the stirring dispersion effect of scraping wall type dispenser, furthermore, scraper blade 11 upper end has vacuum seal cover 6, be equipped with dedicated vacuum extraction mouth 7, raw materials delivery port 8 and exhaust emission 9, prevent that harmful dust and gas from discharging in the external environment, and then protect operational environment.
Then, arouse the PLC controller through touch panel, start pump station 19 in the lifting unit, pump station 19 and control valve 20 combined action, supply 3 flows and pressure of pneumatic cylinder together, realize lifting unit's lift, and then adjust the height of (mixing) shaft 14 in agitator 10, different height is also different to stirring dispersion effect, according to empirical value, when the height of dispersion impeller 12 apart from the agitator 10 bottom is one third of agitator 10 diameter, stirring effect is the best, consequently, through adjusting lifting unit, set up the height of dispersion impeller 12 apart from the agitator 10 bottom as one third of agitator 10 diameter, wherein pneumatic cylinder 3 one side ann has guide bar 4, prevented the toppling of pneumatic cylinder 3 in the lift process.

Through the above operation steps, under the conditions that the rotation speed of the scraper 11 is 60rpm, the rotation speed of the stirring shaft 14 is 1200rpm, the height of the dispersion disc 12 from the bottom of the stirring barrel 10 is 0.17m, the materials are high-viscosity fluid and solid, and the like, as can be seen from the flow diagram shown in fig. 8, the flow field in the stirring barrel 10 generates a four-vortex annular flow field: 2 dispersion discs 12 are uniformly distributed at the upper part and the lower part and are symmetrical left and right; the flow field in the stirring barrel 10 is mainly radial flow.
The speed of both ends of dispersion impeller 12 is the biggest, dispersion impeller blade 13 both ends produce horizontal efflux, plus the rotary motion of scraper blade 11, thereby drive surrounding fluid fast and flow to all around, hit behind the inner wall of agitator 10, divide into 2, one upwards flows along the inner wall of agitator 10, then turn to, flow back to the tip of dispersion impeller blade 13 downwards, another flows to the agitator 10 bottom along the inner wall of agitator 10, flow is restricted after hitting the agitator 10 bottom, change into radial flow and flow to the (mixing) shaft 14 direction, then turn to upwards flow back to the tip of dispersion impeller blade 13, form a vortex ring respectively from top to bottom at the both ends of dispersion impeller blade 13, totally 4 vortex rings, wherein because the stirring of scraper blade 11, fluid's flow has been accelerated, thereby the formation of four vortex rings of quickening.
As can be seen from the integrated velocity cloud diagram of the plumb surface shown in fig. 9, which depicts the velocity flow field distribution in the mixing tank 10, the highlight is the highest velocity shown in fig. 9, and the highest velocity is at the two ends of the dispersion disc blade 13; the lowest speed is in the bottom area of the stirring barrel 10 and the top area of the stirring barrel 10; the low speed area of the bottom of the stirring barrel 10 is relatively small because the lower blades of the dispersion disc blades 13 are tightly attached to the bottom of the stirring barrel 10.
In the above operation steps, taking the heights of the stirring shaft 14 as 0.13m, 0.25m and 0.4m, respectively, as shown in fig. 10, the following conclusions can be drawn:
(1) at a position where the height of the agitating barrel 10 is 0.13 m: the volume fraction curve has large fluctuation, the lowest volume fraction is 30 percent, and the highest volume fraction is about 35 percent;
(2) at a position where the height of the agitating barrel 10 is 0.25 m: the volume fraction curve changes more stably, namely the stirring and mixing in the stirring barrel 10 at the position are more uniform;
(3) at a position where the height of the agitating barrel 10 is 0.4 m: the volume fraction curve has the smallest variation amplitude, namely the stirring and mixing effect in the stirring barrel 10 is the best at the position.
