And the method of collecting and treating sludge in a concrete or other cutting device according to the present invention.

(1) Preparation for Cutting Operation First, before starting the cutting operation for the surface to be processed, cooling water W such as tap water is appropriately poured into a cooling water tank 14 of a water storage tank 10 as shown in FIG. Water is supplied from the inlet 14a using a hose or the like. When the water is supplied and the inside of the container body 11 is almost completely filled with the cooling water W, the bottom of the sludge water tank 15 is pushed up by the cooling water W and contracts slightly as shown in FIG. .

(2) Cutting Operation When the cutting operation is started, the cooling water pump 41 is driven, and the cooling water W in the water storage tank 10 is injected from the injection nozzle 40 to the blade B. Fig. 5
As shown in (c), the cooling water tank 14 of the water storage tank 10
The cooling water W inside decreases. Although the cooling water W decreases,
Since the sludge water L is collected in the sludge water tank 15 and the volume of the sludge water tank 15 increases, the water level of the cooling water W hardly changes as shown in FIG. 5, and the cooling water W is always cooled from the water supply port 14b at a substantially constant high water pressure. The water W is discharged, and the load on the discharge pump 51 is light. On the other hand, blade B
With the cutting by the cooling water W, the sludge water L comes out around the blade B by the cutting powder or the cutting pieces, and this is collected by the sludge water collecting mechanism 5 and the sludge water tank 15 of the water storage tank 10.
Sludge water L inside increases.

The operation state of the sludge water collecting mechanism 5 will be specifically described. The driving of the prime mover is transmitted to the discharge pump 51 via a transmission belt, a speed reducer, and the like.
1 is driven, and the suction blower 52 is also driven via the transmission belt. As a result, a suction force is generated in the sludge water communication pipe 55 connected from the drain pipe 55c and the exhaust pipe 55b to the suction pipe 55a via the vacuum tank 53, and air and water in the blade cover 6 are generated. , Mud, swarf, etc., are sucked into the vacuum tank 53. Further, these are classified into air A, sludge water L, and solids S such as cutting chips in the vacuum tank 53. Among them, the air A is sent to the suction blower 52 via the exhaust pipe 55b, Air is exhausted downward from the cutting device 1 from 52a. The solid content S is collected by a dust collection basket 54 having a water permeable structure, and the upper lid 12 of the vacuum tank 53 is opened as appropriate.
From here, the dust collecting basket 54 is taken out and discarded.

With the progress of the work, the sludge water L in the sludge tank 15 is
The cooling water W in the cooling water tank 14 increases in the opposite direction.

The operation of the equilibrium mechanism 19 will now be described. In the case where the sludge water L is injected to one place of the sludge tank 15 and the bottom of the sludge tank 15 is inclined, the sludge is inclined. The wire 19 close to the point is pulled downward, so that the wire 19 attached to the shape-retaining frame 18 at the other corner is also pulled downward by the same length. Therefore, the bottom of the sludge tank 15 is always kept horizontal.

(3) Treatment of Recovered Sludge Water The collected sludge water L in the sludge water tank 15 is charged with a coagulant 74 and stirred by a stirrer 75 as shown in FIG. 6. As shown in FIG.
Is pumped out to the small bag 70. The sludge water L pumped into the subdivision bag 70 is left for a while, and the sludge L2
Spontaneously settles, and sludge L2 is present below, and separated water L1 is present above. The separated water L1 is supplied to the separated water supply line 73.
To the cooling mechanism 4 side of the cutting device 1 to be used again as the cooling water W. The separated water L1 may be discarded. On the other hand, the solidified sludge L2 remaining in the small bag 70 is discarded or reused for various purposes.

The sludge water L collected as described above
In addition to processing using the divided bags 70, depending on the collection method of the collection company or the like, for example, a large bag may be used,
In the case of taking the form of pumping with a vacuum car, a rigid container may be used.

The above is an embodiment in the case where the sludge water recovery mechanism 5 of the present invention and the cutting device 1 having the same are used for cutting a road surface paved with concrete, asphalt, or the like. The recovery mechanism 5 and the cutting device 1 having the same are not limited to this, but cut the concrete base or block, or support the main body frame 2 by guide rails in place of the traveling drive wheels 30 and the auxiliary wheels 31. For example, by driving a screw shaft with a ball screw or trapezoidal screw and a female screw block screwed to the screw shaft, and attaching a circular saw blade or a disk-shaped grindstone in place of the blade B, wood or metal material It is also possible to use it as a cutting device 1 for cutting.
