The rotation of dynamic spiral stirring blade.
The design feature of mining multifunctional of the present invention from mixing-filling device is lain also in：The feed pipe and tremie pipe it
Between set and return and wash pipeline, it is described return to wash to set to return in pipeline wash valve, in the powder outlet of the lower feed box, baiting valve is set,
The bottom liquid inlet mouth of the liquid supply box sets stirring valve.
It is of the invention to be from the characteristics of control method of mixing-filling device using mining multifunctional：Powder is put into lower feed box
Agent, feed flow main valve is opened, feed flow opens stirring valve and baiting valve after ejector produces jet, and liquid passes through in feed pipe
Feed tube flows into liquid supply box, then flows into discharge pipe by drain pipe, makes to produce vortex in liquid supply box, is rotated with this impeller,
Spiral stirring blade and the rotation of flabellum stirring knife in lower feed box are driven by driving chain, when feed flow flow velocity or flow increase or is reduced
When, impeller also can accelerate or weaken therewith, so as to reach Automatic-feeding and the rationally effect of control pulvis dosage.
The present invention is to utilize to form pressure drop when there is the gas of certain pressure or liquid flow to cross crawl space, and is therefore produced
Suction, the pulvis of top lower feed box to be drawn, while vortex is produced by liquid self-flowing in liquid supply box, impeller rotates, and
Conducted by the bearing, rotating sprocket and driving chain that are equipped with, drive the spiral stirring blade in lower feed box, reach and stir
Mix effect.As long as liquid constantly feed flow, pulvis will be constantly inhaled into and uniform stirring.Compared with the prior art, this hair
It is bright to have the beneficial effect that：
1st, the present invention changes control discharge quantity by liquid supply rate, makes dispensing more uniform, eliminates grume and pipeline blockage
Phenomenon, improve slurry dissolved effect.
2nd, the present invention be with underground geomantic omen loine pressure as power, without electricity consumption, prevented electrical equipment lose it is quick-fried etc. hidden
The generation of trouble.
3rd, light structure letter knot of the present invention, conveniently moving, significantly reduces hand labor intensity, avoids pulvis to body
Injury.
