Using the sedimentation-type compression dewatering vacuum suction vehicle configured as described above to explain the operation process of collecting the sludge of the sewage pipe, it will be described for the effect of the vacuum suction vehicle according to the present invention.

In order to collect the sludge in the sewage pipe using the vacuum suction vehicle configured as described above, the sludge collection hose 210 is introduced into the sewage pipe, and the vacuum generator 100 is driven to drive the internal air of the vacuum suction tank 200. By forcibly discharging to the outside to form a vacuum in the vacuum suction tank 200.

As such, the vacuum suction of the sludge is made by the vacuum formed inside the vacuum suction tank 200, and the sludge introduced through the sludge collection hose 210 and discharged into the interior of the sludge induction apparatus 400 is an external wall 410. Spiral trajectory is lowered along the flow path formed by the inner wall surface and the flow guide member 420 of the), the flow rate of the sludge decreases during the flow of such sludge, some sludge flow guide member 420 Since the sludge is naturally dispersed while falling over the wall portion 422 forming the sludge, it is possible to minimize the impact generated when the sludge falls.

As such, when the drop shock generated by the sludge collected by the vacuum suction tank 200 is minimized, solids formed on the bottom of the vacuum suction tank 200 may be prevented from being injured due to the drop impact of the sludge, and thus the solids may be By preventing the reduction in the form of sludge has the advantage that can increase the separation effect of the sludge and water.

Meanwhile, when the sludge collection operation is impossible due to the capacity of the vacuum suction tank 200 or when the sludge collection operation of the sewer pipe is completed, the water and sludge are separated by driving the cylinder 370 to advance the compression plate 300. The sludge dewatering operation is performed, and the control unit 260 determines the amount of sludge collected by the vacuum suction tank 200 using the weight value of the vacuum suction tank 200 detected from the weight sensor 250. When it is determined that a large amount of sludge has been collected in comparison with the preset reference value, the compression plate 300 is gradually moved to reduce the load on the compression plate 300, the cylinder 370, and the peripheral parts, and vice versa. If it is determined that a small amount of sludge has been collected is to move the compression plate 300 quickly to shorten the working time.

By varying the moving speed of the compression plate 300 according to the amount of sludge collected in this way, it is possible to prevent the damage caused by the overload is transmitted to the parts associated with the compression plate 300, if the amount of sludge is small, the working time There is an effect that can be shortened.

On the other hand, when the sludge is compressed by the forward movement of the compression plate 300, the water separated from the sludge is floated upward of the vacuum suction tank 200, some of the floating water is an opening 310 formed in the compression plate 300 It is introduced into the filtered water separation space (S2) beyond.

In addition, a portion of the sludge flowing together with water to the front of the compression plate 300 during the forward movement of the compression plate 300 is filtered by the filter net 340, the filtered water filtered sludge through the filter net 340 is a filtration chamber ( It is discharged to the discharge passage 360 via 350.

Since the filtered water discharged through the discharge passage 360 is discharged toward the first guide block 320, the heat generated by friction between the guide rail 220 and the first guide block 320 can be effectively cooled. It becomes possible.

Meanwhile, by discharging the filtered water introduced into the filtered water separation space (S2) back to the sewage pipe, it is possible to secure a space for additional collection of sludge, so that it is possible to perform additional collection of the sludge without moving to the sludge treatment site. do.

Meanwhile, the vacuum suction vehicle which has completed the collection of the sludge moves to the place where the sludge treatment facility is located and discharges the sludge. The discharge of the sludge is performed by the compression plate 300 moving forward while the gate 230 is opened. By pushing the sludge.

When the discharge of the sludge is completed by the forward movement of the compression plate 300, the high pressure water is injected from the washing nozzle 240 installed in the gate 230 to perform the cleaning operation for the filter net 340 automatically The convenience of maintenance can be improved.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
