クリュープレス脱水機に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a screw press dehydrator used for dewatering sewage sludge, various industrial wastewater sludge, etc., or solid-liquid separation in the manufacturing process of various products. More specifically, the cake that is dehydrated by being pressed in the axial direction of the screw cylinder by the screw is repeatedly expanded in the circumferential direction of the screw cylinder and pushed back inward while being suppressed in the axial direction.
This invention relates to a screw press dehydrator equipped with a cake cutter that improves dewatering efficiency.

。Conventionally, a screw press dehydrator equipped with a cake cutter has a fixed plate with a circular hole near the discharge port of the screw cylinder, and an oblong hole with both ends formed by an arc with the same diameter as the circular hole of this fixed plate. Screws are passed through the name tag and a large number of sliding plates are arranged alternately, and the sliding plate is inserted between the positions where the arc of the end of the oblong hole of the sliding plate and the circular arc of the circular hole of the fixed plate overlap. It is known that the oblong hole is made to slide back and forth in the long sleeve direction (Special Publication No. 156 of 1983).

圧のみの場合より脱水効率を向上させることができる。According to the screw press dehydrator equipped with the above-mentioned cake cutter, the cake is suppressed in the axial direction of the screw cylinder as the screw rotates, and the reciprocating sliding of the sliding plate suppresses the cake.
It is possible to repeat the process of expanding the cake in the circumferential direction of the screw cylinder in the oblong hole of the sliding plate and pushing the expanded cake back inward again, which improves the dewatering efficiency compared to the case where the cake is simply suppressed by the screw. can be improved.

るものである。In other words, the moisture in the deep part of the cake does not easily move to the surface, so it is difficult to separate into layers, but when the cake is repeatedly expanded and pushed back, the vibration action promotes the movement of the moisture in the deep part of the cake to the surface side. This improves dehydration efficiency.

だまだ改良の余地が残されている。However, in the screw press dehydrator equipped with the cake cutter described above, the cake swells and pushes back intermittently in alternating downward and left-right directions due to the reciprocating movement of the sliding plate, resulting in severe pulsation of the cake. However, there is a drawback that leakage of solids from the gap between the fixed plate and the sliding plate from which water is drained is severe. Moreover, the impact caused by this rapid pulsation of the cake shortens the life of the device. Furthermore, since the cake expands and pushes back only in one direction, up and down or left and right, the moisture in the deep part of the cake cannot be moved uniformly to the surface over the entire cake, and improvements are still needed to improve dewatering efficiency. There is room left.

られている（特公昭５Ｃ１−５８１９号公報）。First, a large number of fixed plates and sliding plates with circular holes of the same diameter are arranged alternately near the discharge port of the screw tube, with screws passing through the name tag, and the circular holes in the fixed plate and sliding plate are arranged alternately. There is also known a device in which the sliding plate is tilted back and forth while keeping the centers aligned (Japanese Patent Publication No. 5C1-5819).

い。However, the above-mentioned screw press dehydrator merely tilts the sliding plate back and forth in order to prevent the gap between the fixed plate for extracting water and the sliding plate from clogging; Since it does not have the function of expanding and pushing back the cake, it is inferior in terms of dehydration efficiency even compared to the screw press dehydrator equipped with the cake cutter described above.

うにすることより達成されるものである。The present invention solves the above-mentioned conventional drawbacks, and aims to provide a screw press dehydrator equipped with a cake cutter that can continuously and uniformly expand and push back the cake from the entire circumferential direction. It is. This object of the present invention is to make the holes of the fixed plate and the sliding plate into circular holes whose diameter is larger than that of the fixed plate, so that the outer periphery of the circular hole of the sliding plate is always located on the outer periphery of the circular hole of the fixed plate. The center of the circular hole in the sliding plate draws a circle with a constant diameter around the center of the circular hole in the fixed plate so that This is achieved by making it possible to successively change the direction in which the cake expands and is pushed back again over the entire circumference of the screw cylinder.

T and the eccentricity T' between the centers Y and Y' of the cam 17 and the rotating shaft 18 are equal, and when the cam 17 rotates,
The center X' of the circular hole 12 is centered on the center X of the circular hole 11, and the eccentricity T between the two holes 11 and 12 (cam 17 and rotating shaft
A circular motion is applied to the sliding plates 10a and 10b, as if drawing a circle with a radius having a length corresponding to the eccentricity T' between the sliding plates 10a and 10b.

が膨出して入り込んでいるものである。As shown in the figure, when the sliding plate 10a (10b) and its circular hole 12 are in the position shown by the solid line, the lower end of the circular hole 12 is in contact with the lower end of the circular hole 11 of the fixed plate 9, and the circular hole 12 is in contact with the lower end of the circular hole 11 of the fixed plate 9. Hole 12
The upper end is located further above the upper end of the circular hole 11, thereby creating a space 20 above. Further, the cake being pressed by the screw 3 expands and enters this space 20.

ても脱水が促進される。When the space 20 moves to the position 12', the space 20 moves to the right side of the circular hole 11, ie, the position 20'. At this time, the cake that had entered the space 20 was removed from the sliding plate 10a (1
0b) and is pushed back inward, and a new cake enters into the space 20' due to the pressing force of the screw 3. Therefore, screw 3
The cake, which has been compressed in the axial direction, is simultaneously repeatedly expanded and pushed back in the circumferential direction, and this vibration action causes moisture in the deep part of the cake to move to the surface, causing separation of the moisture. dehydration efficiency is improved. In addition, the cake exposes new surfaces into the apparatus by expanding and pushing back, and dehydration is also promoted by constantly changing the surface of the cake, which is prone to moisture separation.

。Since the cake is expanded and pushed back continuously over the entire circumference due to the circular movement of the sliding plate 10a0 (10b), the entire cake can be dehydrated uniformly and the cake can be dehydrated evenly. There is also very little pulsation, and there is no risk of a large amount of solid matter leaking out from the gap between the fixed plate 8 and the sliding plate 10a (10b) for drainage, or that the life of the device will be shortened due to the impact of pulsation. . The reason why there is almost no pulsation in the cake is that when the cake is expanded and pushed back intermittently as in the conventional method, a load is applied intermittently from the circumferential direction to the cake that is being advanced by the screw 3. In contrast, in the present invention, the load applied to the cake from the circumferential direction is constant and continuous.

In this case, instead of making sure that the circular holes of all the sliding plates are always at the same position with respect to the circular holes of the fixed plate, as shown in the figure, the circular holes of each sliding plate should be It may be arranged so that the cake is expanded and pushed back radially at the same time by being positioned slightly offset from the hole. For this purpose, the eccentric direction between the circular hole centers of the fixed plate and the sliding plate,
The eccentric direction between the cam and the center of the rotating shaft may be slightly shifted between each sliding plate. In this way, the cake is expanded and pushed back radially at the same time, which is more effective in promoting dehydration.

Since this is carried out continuously over the entire circumference, a screw press dewatering machine equipped with two cake cutters can be obtained with uniform dewatering and less pulsation.
