The present invention relates to a sludge dewatering device of a multi-plate outer cylinder type screw type, more specifically, the sludge introduced into one side of the outer cylinder is moved to the outlet side by rotating the expansion compression screw, and the sludge is dehydrated as well as the outlet side. As the screw shaft becomes thicker and the outlet side space portion is made smaller, the sludge conveyed by the rotation of the expansion compression screw is further compressed and dehydrated while rotating the outer cylinder to increase the dewatering efficiency of the sludge, and the angle of the outer cylinder is increased. A myriad of fluidized plates forming a casing flow in and out of the reciprocating motion by the screw blade surface contact of the expandable compression screw that rotates the inside of the outer cylinder, thereby preventing clogging between the gap formed by the fixed plate and the fluidized plate and preventing the discharge of moisture. It is to facilitate.

In general, waste sludge generated in various wastewater treatment plants is dewatered to be solid by a dewatering device for environmental protection. The dewatering device is a filter press type or a belt press type dewatering device, and these sludges are covered by a filter cloth. While dehydration was performed by pressing roller while dehydration was performed, the filter / belt press-type dehydration device as described above caused clogging of the filter cloth, which lowered the dewatering efficiency and also required installation of various auxiliary equipment according to dehydration. As the bar apparatus is enlarged, manufacturing costs are high, and the installation area has to be large.

On the other hand, in recent years, a screw type dewatering device for dewatering the sludge using the rotational force of the screw in consideration of the manufacturing cost and the installation area as described above has been proposed as a domestic patent publication No. 97-0121733, which is a number of fixed plates Is placed in the gap, and the flow plate can be moved therebetween, and the screw is rotatably installed in the inner space of the fixed plate and the flow plate, and the sludge is inserted into the space and the screw is rotated. Water is removed as the sludge is compressed and moved, and the water is discharged to the outside through the microgap (gap) between the fluidized plate and the fixed plate, and the microgap is blocked by the sludge (solid content) by the movement of the fluidized plate. It is configured to facilitate the discharge of water without work.

Therefore, according to the screw-type dewatering device, it is possible to reduce the manufacturing cost by miniaturization and to have a small installation area.

6 to 7 show a screw type dewatering apparatus proposed by Korean Patent No. 372601 according to another conventional technology. The screw type dewatering apparatus improves the automatic cleaning and improves the life of the fluidized plate and its driving means. And a casing (100) having a supply part (110) and a discharge part (120) formed at both sides thereof, for the purpose of simplifying repair thereof when the fluidized plate driving means is worn out, and the casing (100). Separation means composed of a plurality of flow plates 104 are arranged so as to swing between the fixed plate 102 and the micro-gap (S) between the plurality of fixed plates 102 fixed in the axial direction at a predetermined interval to each other ( 101, the screw 130 inserted into the space portion 105 formed in the separating means 101 and the screw 130, and the flow plate 104 driving means driven in conjunction with the flow, The plate drive means has at least two supports on the fluid plate 104. A hole 104a is formed to be inserted into each of the connection pipes 106 and the connection pipes 106 so that the flow plates 104 are connected to each other, and are supported on both sides of the casing 100 and inserted into the connection pipes 106. It is formed by the rotating shaft 108 provided with the cam 107 in contact with it, and is configured to evenly swing the fluid plate 104. Also, when the screw 130 is rotated, the sludge is rotated in one side by the screw 130 (the discharge part side). Moisture is removed as it is moved and compressed, and the water is discharged to the outside through the micro gap S between the flow plate 104 and the fixed plate 102, and the micro gap S is operated by the cam 107. The water was discharged without being blocked by the moving plate 104, which is also miniaturized, resulting in a reduction in manufacturing cost and minimizing the installation area compared to the filter / belt press type dehydrator.

However, the conventional screw-type dewatering device has a smaller installation area than the filter / belt press type dewatering device, but has a structure in which the fluid plate 104 is moved by the cam 107 operation. The spacer 109 is fitted to the inner surface of the fixed plate 102 to form a micro gap S between the fluidized sheet 104 and the flow plate 104. The structure is complicated, making assembly difficult and repairing and replacing in case of failure. It takes a lot of time to dismantle and assemble for this case there was a defect that the treatment capacity of the sludge is reduced.

The present invention has been made to solve the above-mentioned drawbacks, as the sludge introduced to one side of the outer cylinder constituting the dehydration device is moved to the outlet side by the rotation of the expansion compression screw, the sludge dewatering as well as toward the outlet side As the screw shaft becomes thicker and the outlet side space portion is made smaller, the sludge conveyed by the rotation of the expansion compression screw is further compressed and dehydrated while rotating the outer cylinder to increase the dewatering efficiency of the sludge, and the angle of the outer cylinder is increased. A myriad of fluidized plates forming a casing flow in and out of the reciprocating motion by the screw blade surface contact of the expandable compression screw that rotates the inside of the outer cylinder, thereby preventing clogging between the gap formed by the fixed plate and the fluidized plate and preventing the discharge of moisture.
