ラリー状の汚泥等の含水物質の脱水等を処理装置
において、該含水物質を撹拌して脱水等処理工程
に供給する撹拌ドラム装置に関する。[Detailed description of the device] This device dehydrates water-containing substances such as slurry-like sludge with a solid content concentration of about 3 to 5% in a processing device, stirs the water-containing substances, and supplies the water-containing substances to the dehydration and other treatment processes. This invention relates to a stirring drum device.

れない。 Conventionally, for example, as a stirring drum device for sludge and flocculant in a sludge dewatering treatment device, a hollow cylindrical drum is continuously rotated about its axis with its axis oriented horizontally, and slurry-like material is fed into the drum. There is known a system in which mixed sludge is supplied to the dewatering process by overflowing from an outlet provided at the center of one end surface of the drum while continuously charging sludge and flocculant. However, with this conventional device, the sludge and flocculant placed in the drum remain in the drum for a short time and overflow from the outlet after being slightly agitated, resulting in insufficient flocculation reaction. This results in a decrease in the dewatering efficiency of the next step, and if the volume of the drum is increased as a countermeasure to this problem, the drawbacks of increasing the size and weight of the device cannot be avoided.

The opening tip is extended to near the other end surface of the drum 5, and a plurality of plate-shaped conveying blades 8 are placed around the inner peripheral surface of the stirring drum 5, as shown in the first and second figures. The blades 8 are provided so as to protrude at an appropriate inclination with respect to the generatrix of the inner circumferential surface at intervals in the direction, and in this case, in relation to the rotation direction of the stirring drum 5, the inclination of the blades 8 is such that when the stirring drum rotates, The direction of inclination is such that the blades 8 send the sludge in the drum 5 in a direction opposite to the outlet 6.

Slurry-like sludge and flocculant are injected into the stirring drum 5 from the flocculant injection pipe 15, and the motor 9
When the stirring drum 5 is started and rotated in the direction of the arrow, the rotating drum 5 and the blades 8 strongly stir and mix the sludge and flocculant, and the blades 8 move the sludge and the like away from the outlet 6. The agitation residence time of sludge, etc. is extended by sending the sludge in the opposite direction, thereby promoting the flocculation reaction. The slurry-like sludge, which is agglomerated solids that have been thoroughly stirred and mixed, is sent to the outlet 6.
It overflows onto the chute 13 and is fed onto the cloth a for the dewatering process.
