On the other hand, in the solidifying agent adding device 300, as described above, the pipe 330 of the path connected between the discharge port 215 of the vertical screw conveyor 210 and the pressurizing pump 220.
Pressurization pump 2 via air valve 340 and check valve 350
A solidifying agent is added and supplied to the sludge from immediately before 20, and is composed of a solidifying agent silo 310 and a solidifying agent supply device 320. The solidifying agent silo 310 is filled with powder such as cement or cement-based solidifying agent to solidify the solidifying agent. The supply device 320 employs a supply device such as a rotary feeder, a table feeder, or a piston feeder, and controls the drive device according to the actual flow rate of the soft mud measured by the flow meter 230 to adjust the supply amount.
The solidifying agent may be a powder as it is or a slurry with water added, and the selection is determined by the degree of mixing depending on the soil. However, it is more economical to use the powder as it is, so use the powder as it is if there is not much difference. When the powder is sent, the pipe 330 may be transferred instead of the flexible screw conveyor. The solidifying agent may be supplied as a powder, but depending on the soil quality, a slurry with water added is desirable in order to mix it uniformly with the soft mud. In the case of slurry-like addition, the solidifying agent supply device 320 is provided with a storage tank equipped with a mixer (mixing stirrer), and a water supply line is connected thereto to make the solidifying agent of the powder into slurry and discharge it to the piston pump. The solidifying agent is 50 to 20 for 1 m 3 of soft mud.
Add at a rate of 0 kg (usually 100 kg). In the present invention, as described above, the solidifying agent is introduced from immediately before the pressurizing pump 220 by using the negative pressure of the pressurizing pump 220 into the sludge that is pneumatically conveyed in the discharge pipe 250.
By rotating the blade of 0, the slurry is sufficiently kneaded with the soft mud, and the powder or water is added and mixed in an amount commensurate with the flow rate of the soft mud, so that the slurry is mixed evenly and well with the soft mud during plug transportation, and the remote destination is reached. After a certain period of time, after a certain period of time has passed (usually 2 to 7 days), it solidifies above the required strength. In other words, the amount of solidifying agent added is
The addition amount is determined depending on whether the strength of f / cm 2 is desired. As a matter of course, the larger the added amount, the faster and harder the solidified. As described above, since the uniform mixing of the soft mud and the solidifying agent in the present invention is efficiently performed during the plug transportation in the discharge pipe, the length of the discharge pipe 250 is at least 50 m.
Is needed. It is also possible to directly equip a dredger with the device of the present invention, dredge soft mud such as sludge on the seabed, perform a solidification treatment, and transport it to a distant destination. The feature of the present invention is that mixing of the solidifying agent and the soft mud has one-stage mixing by rotation of the pressure pump and two-stage mixing by repeated operation of plug generation to destruction in plug transportation in the discharge pipe. This is that the stirring is sufficiently performed and the homogeneity (kneading degree) is very high.

Industrial Applicability As described above, in the softening treatment pressure feeding device of the present invention, mud feeding, transfer, solidifying agent feeding, kneading, and discharging are automatically performed in a continuous operation. As described above, since a solidifying and kneading step is not required separately, an efficient and uniform mixed and solidified softened sludge can be obtained.
Further, since the solidifying agent is introduced from the pressure pump, the solidifying agent is easily supplied, and the kneading with the soft mud is sufficiently performed, so that a more uniform mixed state is secured.
