The present invention relates to a dredging vehicle, and more specifically, to separate the sewage and pure sludge from sludge deposited in the sludge tank to drain the sewage and to load the pure sludge only in another means of transportation to be directly transported to the waste treatment plant It is about dredging cars.

In general, in the stagnant section inside the sewer pipe, concrete corrosives, various wastes and sludges that fall off the inner wall accumulate, and the sediment not only prevents the smooth drainage of sewage, but also the sewage pipe is gradually blocked. As the pressure increases, the sewage flows out of the gaps such as pipe joints and cracks, which causes a serious problem of contaminating soil as well as groundwater. In addition, sediment causes a problem that sewage flows back during the rainy season or during heavy rains.

Therefore, in order to prevent this risk, dredging work is required to periodically clean sewage pipes to remove sediments so as not to disturb the flow of sewage. And such dredging work is usually performed by dredging cars. That is, the sewage pipe which is blocked by the ultra high pressure water injection method using the high pressure jet jet cleaner equipment is drilled, and the sludge which is separated from the sewage pipe is recovered by the vacuum suction method using the vacuum pump.

Referring to FIG. 1, a conventional dredging vehicle 1 has a double tank 5 mounted on a vehicle body 2, and the double tank 5 is used as high pressure water for scraping sludge and dirt from a sewer pipe. It is configured to be separated into the water tank (3) to be stored and the sludge tank (4) for recovering the sludge after the dredging operation. Of course, depending on the vehicle, the water tank 3 and the sludge tank 4 may be separated. And the water stored in the water tank (3) is injected at a high pressure through a high pressure water pump (not shown) and at the same time provide a driving force of the jet nozzle (6), the jet nozzle (6) is deposited in the sewer pipe by the driving force After scraping out the sludge and the dirt, it is made of a structure for collecting the sludge and dirt containing sewage and dirt by using the suction pipe (8) through the vacuum pump (7) to recover the sludge tank (4).

This conventional dredging car has no problem in performing the fundamental purpose of removing sludge and sewage in the sewage pipe, but there was a problem in the post-treatment work to treat the sludge and sewage that is recovered to the sludge tank during dredging work. In other words, since the waste treatment shop does not accept the mixed waste of sludge and sewage, it was necessary to separate the sludge and sewage when the waste is treated. Therefore, conventionally, after opening the door provided in the sludge tank, the sludge and sewage stored in the sludge tank are first transferred to a separate loading box (a specially designed loading box for separating the sludge and the sewage), and the sewage is separated from the loading box and drained. The sludge was then disposed of by sludge being transported back to a separate vehicle (eg, dump truck, etc.) and transported to a waste treatment plant.

As described above, the sludge treatment operation is very inconvenient and cumbersome. In addition, there is a problem in that the yard to which the loading box is installed is limited because the loading box for separating sludge and sewage is expensive and smells bad. In other words, because of the lack of the installation place for the loading box, not only the work of transporting the sewage sludge to the place where the loading box is installed is very inconvenient, but there is a problem in that it takes time and cost.

The present invention has been made to solve the problems as described above, the purpose is to separate the waste recovered in the sewage pipe into pure sludge and sewage by sedimentation in the sludge tank, the sewage through the drain It is to provide a dredging car that can drain the natural sludge and transfer only the pure sludge to the vehicle by using the transfer screw.

In order to achieve the above object, the dredging car according to the present invention maintains the sludge tank in a vacuum, and in the dredging car to collect and recover the sludge and sewage in the pipeline into the sludge tank through the suction pipe associated with the sludge tank, At the bottom, the conveying screw is rotatably installed by the drive motor, and is configured to force the sludge to the sludge discharge port. A cylinder is installed at a part of the sludge tank, and when the cylinder is extended, the sludge tank is lifted around the hinge. The front part (or rear part) can be lifted and placed at an angle while rotating at a predetermined angle so that the sludge tank can be lifted up and slanted when discharging the sludge, so that the sewage falls naturally and pure sludge is removed. To be discharged It is characterized by.

And the bottom of the sludge tank is installed so that the sludge is introduced into the guide slant plate having a predetermined angle is gathered in one place, characterized in that the conveying screw is installed in the sludge collecting portion.

In addition, a plurality of drainage holes are formed in the guide inclined plate so that wastewater can be drained into the space between the guide inclined plate and the bottom surface of the sludge tank, and at least one drain hole is formed in a portion of the sludge tank corresponding to the space. The drain port is provided with a drain valve so that it can be selectively opened and closed, it is also characterized in that the filter is installed to filter the sludge and drainage only sewage.

Here, the method of treating the sewage and sludge recovered in the sludge tank 120 will be described in more detail. First, as shown in FIG. Sludge (S), including the sludge tank 120 is to be concentrated to the rear portion of the gather. Then, the conveying screw 200 is placed inclined, the pure sludge (S) is sedimented in the lower portion of the conveying screw 200 placed inclined, and the phenomenon is separated from the sewage (W).

In this state, first to open the corresponding drain valve (B1) to drain the sewage (W), and then operating the drive motor (M) to rotate the transfer screw 200. Then, only the pure sludge S is forced to be inclined upwardly along the transfer screw 200, and the transferred pure sludge S is discharged through the sludge discharge port 220 and is guided to the discharge guide hose 222. It is loaded on a vehicle T such as a dump truck. At this time, since the pure sludge S is guided and discharged upward along the conveying screw 200, the sewage W automatically falls into the sludge tank 120, and as a result, only pure sludge S is discharged. Next, the pure sludge S loaded on the vehicle T is directly transported to a waste treatment station for disposal.

Meanwhile, in the above-described embodiment, the dredging vehicle equipped with the double tank in which the water tank and the sludge tank are integrally described has been described.

Of course, the driving motor for driving the conveying screw is shown in the rear of the sludge tank in the drawing of Figure 7, the present invention may be installed in the front of the drive motor, the drive motor may be installed outside the sludge tank There will be. In addition, although the drive motor and the transfer screw is installed in the drawing is directly connected, it may be configured to transmit power using other power transmission means.

Meanwhile, in the above embodiments, an unshown heater is installed on an inner portion of the sludge tank to prevent the transfer screw installed in the sludge tank from freezing in winter, and the heater is installed by a temperature sensor not shown. When the temperature inside the sludge tank is received below the set temperature by receiving a signal, it is preferable to be configured to generate heat. That is, it is preferable to configure the feed screw so that the freezing phenomenon does not occur in winter by preventing the sewage and sludge inside the sludge tank from freezing while the heater generates heat.

As described above, the present invention is to separate the sludge and sewage in the sludge tank, the sewage is discharged separately to the sewage sewage, but the sludge is transferred to the transport means there is an effect possible to work. In other words, since the sludge is separated from the dredging car and can be transported directly to the waste treatment station through a transportation method, it is not convenient to go to a separate intermediate treatment place and separate the sludge and sewage first, and then send the sludge to the waste treatment station. There is no box, therefore, it is very convenient to provide a work site, and there is an effect that can shorten the time for sludge post-treatment work.
