いる。2. Description of the Related Art When a large amount of sludge is generated from garbage or the like containing a large amount of water, from the viewpoint of pollution problems, a dewatering treatment is performed without dumping as it is, and the sludge is separated into dehydrated sludge and water. Must be processed separately. As an efficient device that can press and dewater such sludge such as garbage and collect it as dewatered sludge that is easy to dispose, a press device using a screw mechanism is used.

By transporting the sludge in a pressurized manner, moisture is squeezed out in the course of the transportation, and is removed from the peripheral surface of the dehydrating cylinder so that the sludge can be recovered. It is to be discharged from.

脱水筒内での有効な前進力が得られず、脱水に長時間を
要し、甚だしくは脱水が不能になる場合があった。However, in the dewatering cylinder using a punching metal having a large number of dewatering holes formed on the peripheral surface, if the sludge is highly sticky, the sludge is dewatered. Often adheres to the screw shaft or core shaft in the cylinder and rotates together with it in an integrated state,
In some cases, an effective forward force in the dewatering cylinder was not obtained, and a long time was required for dewatering, and in some cases, dehydration became impossible.

However, there is a problem that the use of a plate having a sufficient thickness is expensive due to drilling.

きる等装置の保守管理に利便性を有している。The screw blades 13 of the screw shaft 5 are fixed to the core shaft 14 by welding so that the interval, that is, the pitch, of the screw blades 13 decreases toward the distal end opening 4a of the dewatering cylinder 4, and the distal end, that is, the discharge end side. The sludge can be conveyed in a pressing manner toward the screw shaft 5.
As the sludge is conveyed, the thrust caused by the rotation of the screw shaft 5 itself acts on the base end due to the reaction force received by the screw blade 13, and the sludge filled in the dewatering cylinder 4 causes one-sided holding. In addition, it is possible to maintain a stable rotation state while being held on the central axis of the dewatering cylinder 4. Furthermore, since the screw shaft 5 is configured as described above, it is convenient for maintenance and management of the device, such that the screw shaft 5 can be easily pulled out of the casing 2 and cleaned after work.

Outer dewatering bar 15A and inner dewatering bar 1 that are alternately arranged in parallel
5B, the inner shell dewatering bar 15B is made to project slightly inward from the adjacent outer shell dewatering bar 15A so that an unevenness is formed in the inner circumferential surface in the circumferential direction. The ratio of the number of the outer shell dewatering bar 15A to the inner shell dewatering bar 15B is 1
An array of about one or two to one is used.

にしてある。The dewatering cylinder 4 shown in FIG. 1 is divided into three parts in the axial direction.
5 is fixed to the mounting plates 17A and 17B to form an end of the dewatering cylinder having an open end. In the middle part, the dewatering bar 15 is fixed to the flange 16, and as shown in FIG. The stretch connection of the dewatering cylinder 4 is enabled by tightening the bolts. This flange 16 has cutouts for the outer dewatering bar 15A and the inner dewatering bar 15B on the inner periphery, and when the assembling is performed, the dewatering bar 15 is disposed so as to fit and form irregularities on the inner peripheral surface. It is designed to be convenient.

よりケーシング２に固定される。In addition, by forming the dewatering cylinder 4 as a divided cylinder that can be connected in this way, not only can the long dewatering cylinder 4 be formed by assembling, but also, for example, the inner diameter of the outer dewatering bar 15A can be changed. It is also possible to change the unevenness of the inner peripheral surface between the dewatering cylinders to perform a dehydration treatment according to the properties of the sludge or to remove foreign substances. In the case of a screw press device having a relatively short length or the like, it is also possible to form the integral dewatering cylinder 4 with the long dewatering bar 15 without dividing. In this case, the flange 16 can be used as a reinforcing member for preventing the swelling of the dewatering cylinder 4, that is, the outward bending of the dewatering bar 15, at the time of treating sludge, instead of the holding ring. The dewatering cylinder 4 thus manufactured is fixed to the casing 2 by the mounting plates 17A and 17B at both ends.

May be assembled together, or may have different thicknesses.
Different types of dewatering bars may be combined in such a manner that the outer diameters thereof are made uniform to provide an unevenness on the inner peripheral surface.

However, a plurality of pitch portions (3 pitch portions in the figure) at the tip end in the axial direction of the screw blade 13
The tip blades 13a, 13b, 13c are not fixed to the core shaft 14, but are slidable. Furthermore, this tip blade 13a
A sliding plate 18 in contact with the tip of the shaft is mounted on the core shaft, and a tension spring 20 is interposed between the sliding plate 18 and a fixed plate 19 attached to the tip of the core shaft 14. Then, at the time of sludge treatment, the thrust applied to the tip blades 13a, 13b, 13c is received by a sliding plate.

By the rotation of the screw shaft 5, the sludge a (FIG. 4) is conveyed to the tip side, that is, the discharge end side by the screw blade 13, and a thrust acts on the base end of the screw shaft 5 by the reaction force received by the screw blade 13, Further, the sludge a which is conveyed in a filling manner in the dewatering cylinder 4 is positioned on the central axis of the dewatering cylinder 4 and continues stable rotation in a cantilever state. The sludge a is compressed in accordance with the tendency of the pitch of the screw blades 13 to shrink, and the contained water is squeezed out. The water flows to the lower part of the casing 2 through the gap between the dewatering bars 15 of the dewatering cylinder 4 and flows out of the drainage cylinder 6. Drained.

Since the resistance in the rotation direction is affected by the unevenness in the circumferential direction due to the dewatering bar 15 on the inner peripheral surface of the dewatering cylinder 4, the rotation integrally with the screw blade 13, that is, the co-rotation is prevented,
It is compressed and transported smoothly forward. In addition, hard foreign objects such as forks and spoons, which had previously been caught in the dewatering hole of the dewatering cylinder made of punching metal and were difficult to discharge, slide along the inner surface of the dewatering bar and are discharged from the opening at the tip. Elongated soft foreign substances such as clogged fibrous materials are also discharged from the dewatering cylinder together with treated sludge or separated wastewater.

Is not exposed to the outside, which is convenient for washing the screw shaft 5 and the like. In addition, a screw blade is fixed to the outer cylinder 22 and a conveying screw is arranged in front to transfer the treated sludge to another place. There is an advantage that can be configured as follows.

A dewatering cylinder formed by a cylindrical body in which the dewatering bar material is arranged in the axial direction is used, and the uneven surface of the dewatering bar material is formed on the inner surface of the dewatering cylinder, so that the treated sludge has a large tackiness. Even if there is, there is no rotation by the screw shaft, and a screw press device with good dewatering efficiency can be obtained. Further, according to this apparatus, foreign substances such as forks, which have conventionally been difficult to discharge, can be easily discharged. Further, according to the present invention, there is an effect that a relatively inexpensive screw press device which is simple as a device mechanism, easy to maintain and manage, and has no problem in strength and durability can be obtained.
