It consists of. The scraper 1732 is provided at the end of the buffer cylinder (1733) is fastened to the mounting frame (1731) on the left side of the support 113 as viewed from the side. The buffer cylinder allows the scraper 1732 to be in close contact with the rotating filter cloth 130, and absorbs the impact applied to the scraper 1732 while the filter cloth 130 is rotated to maintain the contact with the scraper 1732. The end of the to remove the remaining foreign matter of the filter cloth (130).

As shown in FIGS. 5 to 7, the frame 110 further includes a meandering adjusting unit 180, wherein the meandering adjusting unit 180 includes a guide hole 182 formed in the filter cloth 130. It consists of a sprocket 181. The filter cloth 130 wound around the plurality of rollers generates meandering while rotating. To correct the meandering of the filter cloth belt, the filter cloth 130 has a pitch at the pitch of the sprocket 181 at regular intervals on both edges of the filter cloth 130. By guiding the guide hole 182 through the teeth of the sprocket 181 is formed and fixed to rotate the guide hole 182 in accordance with, thereby not only to rotate the filter cloth 130 but also to correct meandering mechanically do. The sprocket 181 is installed on two rollers left and right when viewed from the side mounted on the upper surface of the lower upper frame 112 among the rollers supported by the lower rotary electrode body 142, both of which are on the axis of the roller. It is mounted at each end.

Hereinafter, an operation method according to a second embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 5 to 7, the sludge is introduced through the hopper 161 of the inlet unit 160, and the introduced sludge is first loaded in the lower portion of the inlet unit 160. The loaded sludge is forcibly pushed out as the rotary blades of the impeller 162 mounted inside the hopper 161 are rotated. At this time, the rubber roller 163 equipped with a plurality of rollers in a split form is impeller 162. Adjust the width of the sludge by pushing the sludge coming out from) closely. In addition, the rubber roller 163 may adjust the thickness of the sludge is pushed up and down by the adjustment handle 164. In this way, the sludge, whose width and thickness are first adjusted, is upper and lower rotary electrode bodies 141 and 142 through the filter cloth 130 which surrounds and rotates the lower rotary electrode body 142 located directly below the rubber roller 163. Flows through). The rotation of the upper and lower rotary electrode bodies 141 and 142 and the filter cloth 130 is performed by the upper and lower driving motors by the supporting roller, the sprocket fastened to the shaft of the roller, and the chain connected to the sprocket. 165), 166 is rotated by receiving the driving force.

Particles of the sludge containing moisture introduced between the upper and lower rotary electrode bodies 141 and 142 bear surface charges having a polarity on the surface in the electric field formed by the power applied from the pantograph 145. The charged sludge particles move in the direction of + electrode by the electrophoresis phenomenon, and the water between the sludge particles moves to the-pole and is discharged by the electropenetrating action. The cell membrane of the sludge particles is then broken under the influence of the electric field, and the binding water inside is discharged toward the electrode by capillary pressure. At this time, the sludge is pressured up and down by a plurality of compression rollers 152 of the pressure applying unit 150 mounted on the upper and lower parts to promote the capillary phenomenon, and only the water is dehydrated by the filter cloth 130. In this case, the discharged water is accommodated in the upper and lower drip trays 116 and 117. Here, the pantograph 145 applies electricity only to the portion of the rotating electrode body in which the sludge is transferred. The other part of the pantograph 145 has the electrode terminal 146 of the pantograph 145 because the rotating electrode body is formed of the electrode body fragment 143. Is not applied, the electricity is not applied can use the power efficiently. In addition, the thickness adjusting unit 120 is mounted on the side of the frame 110 and fastened to the end of the cylinder 123 of the upper frame 111 and the thickness adjusting unit 120, the cylinder of the thickness adjusting unit 120 ( Whenever the 123 rises and falls to raise and lower the upper frame 111, the upper rotating electrode body 141 mounted on the upper frame 111 is raised and lowered, and the lower rotating electrode body 142 is lowered. It is fixed to the upper frame 114 to adjust the gap between the rotating electrode body. As a result, not only the throughput of the sludge transferred between the rotary electrode bodies but also the pressure applied to the sludge according to the water content of the sludge to be transported can be adjusted, and the intensity of the electric field can be adjusted by adjusting the distance so that efficient dehydration can be performed. have.

In addition, after the sludge is discharged, the remaining material of the sludge on the filter cloth 130 is first removed by the scraper 1732 of the belt cleaner unit 1730 mounted on the left support 113 of the frame 110. The buffer cylinder 1735 of the belt cleaner unit 1730 applies a force to absorb the impact so that the scraper 1732 is in close contact with the filter cloth 130 at an appropriate pressure. Secondly, the residual material of the sludge buried on the rear surface of the filter cloth 130 is washed by water sprayed by the nozzle 1712 connected to the pipe 1711 of the filter cloth cleaning unit 1710 mounted on the lower lower frame 114. . The remaining material of the sludge buried in front of the filter cloth 130 is a nozzle 1712 connected to the pipe 1711 of the filter cloth cleaning unit 1710 mounted on the guide frame 133 of the tension control roller 131 It is washed by spraying water. In addition, the residual material of the sludge buried in the upper and lower rotary electrode bodies 141 and 142 is viewed from the side of the upper frame 111 and the roller brush 1721 of the electrode cleaning unit 1720 mounted on the lower left side. The roller brushes 1721 of the electrode washing unit 1720 mounted on the lower left side of the lower upper frame 112 are respectively removed, and the roller brushes 1721 are fastened to the motor roller 1723 having an independent driving force. Therefore, the roller brush 1721 is rotated at a speed different from that of the rotating electrode body, thereby wiping the surface of the rotating electrode body.

In addition, when the device is driven, the filter cloth 130 in contact with the sludge causes meandering due to the transfer of the sludge having a high viscosity. When the meandering of the filter cloth 130 occurs, the sprocket 181 mounted at the end of the shaft of the roller located at the left and right as viewed from the side of the lower upper frame 112 with guide holes 182 formed at regular intervals on both edges of the filter cloth 130. By passing through the teeth of the c), the filter cloth 130, which is twisted between the rollers mounted on the left and right sides, is forcibly returned from the side mounted on the frame 110, and is corrected by returning to the position of the fixed sprocket 181.

In addition, when the filter cloth 130, which is wound around the sprocket 181 and wound around the sprocket 181, sag occurs, the cylinder 132 for adjusting the tension of the filter cloth 130 mounted on the right support 113 as viewed from the side. ) Pushes out the tension adjusting roller 131, and the filter cloth 130 wound around the tension adjusting roller 131 is pushed out accordingly to recover the tension.

Although the present invention has been shown and described with respect to specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
