The utility model content
The technical problem that the utility model will solve provides and a kind ofly can improve the dregs performance, and bentonite slurry simple in structure, that be convenient to operate stirs the fermentation transferring box.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of bentonite slurry stirs fermenting case; It is characterized in that: comprise casing and agitating device, said casing upper center is provided with the crossbeam that is used for fixing agitating device, and the casing upper surface is provided with charging aperture for one jiao; Said charging aperture is equipped with screen pack, and the sidewall below of casing is provided with discharging opening.
The top of said casing is provided with the crisscross guidance tape of walking, and the one of which side is provided with cat ladder.
Said agitating device comprises stirring motor, the shaft that connects through shaft coupling and the stirring vane that is fixed in the shaft middle part, is provided with reductor between said stirring motor and the shaft coupling, and said reductor is walked on the guidance tape in said through bolt.
Viscosity measurements device and device for detecting density are installed on the crossbeam of said casing.
The utility model is exactly after bentonite is mixed the system link; Increase swivel link in the fermentation, utilize a kind of bentonite slurry to stir the fermentation transferring box, hold the bentonite slurry of generous amount through casing; Rabbling mechanism stirs mud is fully fermented, and is delivered to shield machine at last.
Adopt the beneficial effect that technique scheme produced to be:
(1) simple in structure.This apparatus structure is simple, and capacity is according to the adjustment of practice of construction demand, and the material of use all is the builder's yard common used material also, is convenient to processing and fabricating.
(2) handled easily.The technical staff arranges the operator that bentonite slurry is placed into casing, and through after filtering the mud of single-size, starts agitating device and stir fermentation, checks current viscosity and proportion that the electric control box display screen shows simultaneously, judges ferment effect.Mud reaches technical standard, can get rid of through discharging opening, otherwise continue to stir.Whole process operation is simple, checks conveniently.
(3) with strong points.This device is used for shield structure building site bentonite slurry and stirs the fermentation transfer, promptly lets bentonitic puffing and adsorptivity be able to performance, also plays the effect that bentonite slurry stores transfer.
