DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process for flowing sludge into a sludge tank, evacuating the sludge tank, arranging a spiral conveyor inside to separate water and earth and sand to reduce sludge and continuously discharge the sludge. Also, the present invention relates to a continuous sludge treatment and discharge apparatus which transports and discards it with a dump truck and returns water to a construction site for reuse.

[0002]

2. Description of the Related Art Conventionally, excavating land while adding a stabilizing solution,
When discharging this sludge, as shown in FIG. 3, a sludge container 101 is placed on a sludge suction vehicle 100, and a sludge tank 10 is placed.
2 is connected to a vacuum device 103 to make a vacuum state, and the sludge containing the earth and sand is discharged from the construction site by a pipe 104 into a sludge tank 10.
2 and stored in the discharge tank 105. The sludge in the discharge tank 105 is stored in the sludge container 1 of the sludge suction vehicle 100.
When the sludge container 101 becomes full, the sludge suction vehicle 100 is operated to transport and discard the sludge container 101 to a predetermined place. This was a one-patch system in which the sludge inside was sucked into the sludge container 101 of the sludge suction vehicle 100.

[0003]

In the above-mentioned prior art, the sludge containing water is discarded as it is, so that the amount of sludge becomes the amount obtained by adding the stable liquid used for excavation to the excavated soil and the amount of sludge is reduced. There was a problem that the water in the sludge could not be reused.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems by connecting a sludge tank having a sludge inlet to a vacuum device and internally providing a spiral conveyor .
In the continuous sludge treatment equipment, the base of the spiral conveyor is
Fix to the lower rear of the sludge tank
Outside the spiral conveyor inside the sludge tank
Cover the circumference with a mesh cover and protrude from the sludge tank
Cover the outer periphery of the spiral screw with a cylindrical cover,
Fix to the tip of the mesh cover and lower the tip of the cylindrical cover.
At the bottom of the front end of the sludge tank
A water discharge device is provided .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the embodiments shown in FIGS. 1 is a sludge tank, 2 is a pipe which connects the sludge tank 1 and the vacuum device 3. The sludge tank 1 helical conveyor 4 is arranged, projecting one end from the sludge tank 1, covered with a cylindrical cover 5 on the protrusion periphery, the mesh cover 6 attached to the spiral conveyor outer circumference of the sludge tank 1, a spiral conveyor 4 strokes
Cover the outer periphery of the protruding part with the cylindrical cover 5 and mesh the base
A sludge inlet 7 is attached to the top end of the cover 6 and a sludge inlet 7 is attached to an upper end of a lower end thereof. Is provided with a sediment discharging device 11. The moisture discharging device 9 and the earth and sand discharging device 11 are configured such that a rubber emperor is rotated in close contact with the inner periphery of the housing and air is not introduced into the sludge tank 1 and a vacuum is maintained to discharge moisture and earth and sand. 12 is the earth and sand discharge device 1
Reference numeral 1 denotes a motor, 13 denotes a motor of the water discharging device 9, and 14 denotes a motor of the spiral conveyor 4.

Next, the operation will be described. The pipe 2 communicates with the vacuum device 3 to make the inside of the sludge tank 1 vacuum.
Next, the sludge containing earth and sand and water is sucked from the construction site 17 by the pipe 2, and the motors 12, 13, and 14 are driven.
The sludge flowing into the lower end of the spiral conveyor 4 from the sludge inlet 7 is conveyed upward while being stirred by the spiral conveyor 4, and during this time, water drops from the mesh cover 6 on the outer periphery of the spiral conveyor 4 to the bottom of the sludge tank 1, The water flows into the water discharging device 9 from the drain port 8 and is discharged to the outside. The discharged water is stored in a drainage storage tank 15, returned to a construction site 17 as construction water by a pipe 16, and recycled. The sediment separated from the water flows into the earth and sand discharge device 11 from the earth and sand discharge port 10 at the lower end of the spiral conveyor 4, is loaded on the dump truck 19 by the external conveyor 18 and is driven by the dump truck 19 when full, and is transported and discarded. .
Sediment continuously discharged is loaded on the next dump truck. In this way, water is continuously discharged and sent to the construction site, and earth and sand is continuously discharged and transported and discarded one after another by a dump truck.

[0007]

According to the present invention, in a continuous sludge treatment apparatus in which a sludge tank having a sludge inflow port is connected to a vacuum device and a spiral conveyor is provided inside , a spiral conveyor is provided.
Fix the base to the lower rear of the sludge tank, and
Screw from the top of the sludge tank
Cover the outer circumference of the bear with a sludge tank
Cover the outer periphery of the projecting helical screw with a cylindrical cover.
The rear end of the mesh cover to the tip of the mesh cover.
Attach a sediment discharge device to the lower end of the
Since the sewage discharge device is provided at the lower part, sediment and water contained in the sludge can be reliably separated with high efficiency .
