The components of the present invention are largely dredged inlet pipe 10, dewatering filter collection box 20, sediment output pipe 30, dewatering roller 40, roller guide line 50, It consists of the shower apparatus 60, the blower apparatus 70, the housing | casing combined use water 80, the piping 90 for processing water discharge, and the control part 100.

Dredge water introduction pipe 10 is a means for introducing an external dredged in the form of a cylindrical or polygonal cylinder. That is, the dredged water intake pipe 10 is a means for initially entering the dredged water input from the outside dredged water intake pipe 10 is a dredged water containing a lot of water.

The dewatering filter collection box 20 is connected to the dredged inlet pipe and serves to discharge water from the dredged water input from the dredged inlet pipe 10 to the outside and leave only the sediment. That is, the dewatering filter collection box 20 is a filter is installed in a cylindrical shape, dredged water is injected into the inner space, sediment from the dredged water does not pass through the filter to the bottom and only water passes through the filter It is discharged to the outside and the moisture is released by the microfibre.

Sediment output pipe 30 is coupled to the lower portion of the dewatering filter collection box 20 is a pipe for discharging the sediment is complete dehydration to the outside. That is, the sediment output pipe 30 serves to discharge all the sediment and the remaining sediment through the dehydration filter collection box 20 to discharge to the outside, and the sediment is treated through the filling of water in the yard.

The dewatering roller 40 is installed on the outside of the dewatering filter collecting box 20 and moves downward while compressing the dewatering filter collecting box 20 to forcibly dewater the dredged water and complete the lower movement. When the left and right unfolded and then moved back to the top and then gathered from side to side serves to compress the dewatering filter collection box (20). That is, the dewatering roller 40 is for separating the water from the dredged water at a high speed, and the dredged water can be quickly discharged by pressing the dredged water as if it is squeezed forcibly, and the sediment is produced at a high speed and can be discharged to the outside. Make sure

The roller guide line 50 is formed in a rectangular frame shape, and serves to guide the central axis of the dewatering roller 40 so as to flow up, down, left, and right. That is, since the dehydration roller 40 flows up, down, left and right along the roller guide line 50, the roller is maintained in a compressed state when descending, and when the compression is completed, the roller 40 is retracted and then rises again along the roller guide line after retreating, and then presses again. Approach toward the dehydration filter collector (20) for

The shower device 60 and the non-contact sensor 61 are installed at one end of the roller guide line 50 in which the dehydration roller 40 rotates. When the dehydration roller 40 is confirmed by the non-contact sensor 61, the shower device 60 and the non-contact sensor 61 are fixed. Water is sprayed for a time to remove foreign substances on the dehydration roller. In other words, the dehydration roller is forced to bury the foreign matter on the outer periphery by pressing the dewatering filter collection box, and if the foreign material is not removed, the dehydration roller is buried in the dewatering filter collection box during the next compression operation. It acts as a cause that the filter hole of the filter collection box 20 is blocked. Therefore, in the present invention, the shower device 60 is operated to spray water on the outer circumference of the dewatering roller 40 after the squeezing is completed to clean the foreign substances on the outer circumference of the dewatering roller, and then put into the next pressing operation. It is to let. In addition, since the shower device 60 is installed on the roller guide line 50 in which the dewatering roller 40 rotates, the working time of pressing the dewatering filter collector is not affected at all.

Blowing air into the blower device 70 in one state to forcibly remove the foreign matter on the dewatering filter collection box (20). That is, when the dewatering operation for a long time using the dewatering roller 40, the dewatering hole of the dewatering filter collection box 20 is blocked by foreign matters, which is a factor that reduces the dewatering efficiency, in the present invention After stopping the dredging at intervals of time and closing the upper part, the air is blown into the blower device 70 to forcibly shake off the foreign matter present in the dewatering filter collecting box 20.

Combined water storage housing 80 is a space in which water discharged from the filter of the dewatering filter collection box 20 is temporarily stored by combining the dredge water intake pipe 10 and the sediment output pipe 30 and secured a space therein to be. In other words, the water-collecting housing 80 serves to temporarily store dehydrated water and at the same time to fix various pipes, and the exterior is manufactured in a cylindrical or polygonal cylinder shape.

The treatment water discharge pipe 90 is installed at one side of the water storage double housing 80 and serves to discharge water existing in the space portion of the water storage double housing 80 to the outside. That is, the treatment water discharge pipe 90 is for discharging the separated water to the outside and is disposed below the water storage housing 80 to naturally discharge to the outside by gravity action.

The control unit 100 drives the shower device 60 according to whether the non-contact sensor 61 is the driving roller 40, and also drives the driving roller 40 along the roller guideline 50, at regular time intervals. It serves as a control for driving the blower device (70).
