13 direction conveying, the stirring rod 14 being installed in wetting stirrer 1 to export direction due to tilting, and the material being stirred is gradually
Also mobile to export direction, in stirring rod whipping process, form mud pearl and through 14 discharge of outlet.
Between the inlet and outlet of water pump be equipped with the control loop with valve, in order to obtain not fugitive dust, do not stick to the pan " mud
This effect of pearl " is provided with return valve in the supply of water-spraying amount, i.e., throttling is filled in fresh water pump water out and inlet ductwork
Valve, so that the extra water of spray line flows back into water inlet, it is ensured that the moisture content of mud pearl is maintained at 25%~27%.Above-mentioned water pump exists
Dust wetting stirs into first humidification starting before the work of pearl device, for moistening wetting stirrer 1.
In the technical solution that above-mentioned dust wetting stirs into pearl device,
It is equipped with gap between the stator and rotor of quantitative device for discharging, when dust temperature is 150 DEG C or more, stator and turns
Gap between son is 1mm~1.2mm.The dust under room temperature is such as stirred, the two gap is generally 0.2mm~0.4mm.
It is slurry condition or mud pearl state since the type selecting of equipment is related to wet dust when exporting discharge, determines
After lectotype selection in the present embodiment, pearl device is stirred into the dust wetting in the present embodiment and is tested, wherein test time
Number 3 (c point) is the test data that the present embodiment obtains, is compared with test number (TN) 1 (a point) and test number (TN) 2 (b point), can
Know:
It should be further noted that the mud pearl obtained is 3 (c of test number (TN) after the type selecting of above equipment determines
Point) corresponding picture respectively mixes 200g powder and 40g, 50g, 60g, 70g water to further prove for test data,
Following test data is obtained, the corresponding picture of test number (TN) 3 (c point) and the following figure are compared, it is found that mud pearl is not glued
Disk, and graininess is preferable, probably close to 200g powder+50g water, that matches and compares moisture content.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that: it still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these modification or
