And movable loose collar, the internal diameter of loose collar is smaller than the internal diameter of fixed ring, is being greater than activity between the two neighboring fixed ring
Adjustment block is provided at the outer end edges of ring outer diameter, the adjustment block is fixedly connected with fastening screw, and the one of the fastening screw
End connect crab bolt connection with first, and the other end of the fastening screw is connect with an end nut of the second connecting plate, the company
The other end of fishplate bar is connect with concentration box body bolt, and roller bearing, the rolling are equipped at the inner diameter edge of the fixed ring and loose collar
The both ends of axis are fixedly connected with the both ends of a sleeve, and the sleeve is sheathed on agitating shaft, and the sleeve and stirring axle bolt connect
It connects, the roller bearing is rotated by sleeve around agitating shaft, and filtered water outlet is equipped between the folded breechblock and agitating shaft.
Another kind as the utility model improves, and the folded breechblock outer ring is equipped with the second stirrer paddle, and described second stirs
The center and agitating shaft for mixing blade are bolted to connection.
A kind of pre-concentration device suitable for folding spiral shell formula sludge concentrator disclosed by the utility model, by agitating shaft
Folded breechblock is installed, is rotated by folded breechblock around agitating shaft, the moisture in sludge can be filtered out into away a part in advance, passed through
Filtrate (liquid discharge, improve the dehydration efficiency of folded spiral shell formula sludge concentrator, utmostly guarantee equipment continue, stable operation.
The utility model is described in further detail with reference to the accompanying drawing.

Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made with reference to the accompanying drawings and examples further detailed
Thin explanation.Following embodiment is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation limitation
The protection scope of the utility model.
As shown in Figure 1, a kind of pre-concentration device suitable for folding spiral shell formula sludge concentrator of the utility model, including concentration case
Body and agitating shaft, agitating shaft are installed in concentration cabinet, and agitating shaft top is connected with stirring motor, and stirring motor is installed on concentration
On cabinet, concentration cabinet side is equipped with mud inlet, and the other side that cabinet is concentrated is equipped with mud mouth, is equipped with folded spiral shell on agitating shaft
Body, folded breechblock include fixed ring and loose collar, are configured with the activity concentric and movable with fixed ring between two neighboring fixed ring
