The invention discloses a circulating treatment device and method for foundation pit mud. The circulating treatment device comprises a sedimentation tank and a plurality of sedimentation tanks located behind the sedimentation tank, a conveying assembly is arranged at the bottom of the sedimentation tank, and a discharging opening used for conveying mud and sand by the conveying assembly is formed in one side of the sedimentation tank. After the muddy water in the sedimentation tank is detected by the turbidity sensing module and the turbidity detection mechanism, the muddy water with different turbidity flows back to the position of the liquid discharge area corresponding to the turbidity parameter, and the liquid at the upper part of the liquid discharge area is conveyed to the bottom of the sedimentation tank at the first position through the conveying pipe; liquid at the upper part of the first sedimentation tank is conveyed to the bottom of the downstream adjacent sedimentation tank through the conveying pipe and is continuously settled, so that muddy water with different turbidity is discharged into the position of the liquid discharging area with corresponding turbidity parameters, the muddy water with relatively high turbidity can be prevented from being discharged into an area with relatively low sludge turbidity, and a water body in the area with relatively low turbidity is prevented from being stirred to become turbid; and long time is needed for secondary precipitation.

The utility model belongs to the technical field of roadway dust removal, and relates to an air flow purification device of a fully-mechanized face air return crossheading, which comprises a frame type component, a lifting component, a lower rotating component, an upper rotating component and a spraying component, the frame type component is used for allowing an operation vehicle to pass through, and the lifting components are arranged on the two sides of the frame type component and used for achieving lifting of an upper structure in the frame type component; a spraying component is arranged in the middle of the upper structure of the frame type component and used for treating dust in an area where a vehicle passes through. The rotating lower part is hinged with one side of the lower structure of the frame type part, and the spraying part is arranged at the upper part of the rotating lower part; the rotating upper part is hinged to the side, close to the rotating lower part, of the upper structure in the frame type part, and a dust catching net is arranged between the rotating upper part and the frame type part. Sufficient passing space is provided for vehicles, obstruction of a traditional dust catching net to traffic is avoided, different roadway heights and environment conditions can be flexibly adapted, and the stability of the treatment effect is ensured.

The utility model belongs to the technical field of sewage treatment, in particular relates to a sludge pre-sedimentation device with intelligent monitoring and adjusting functions, and provides the following scheme aiming at the problems that the existing sludge pre-sedimentation device cannot clean sludge in time, the sedimentation effect is reduced when the sludge pre-sedimentation device is continuously used, and the sedimentation of the sludge is influenced in the water flowing process: the sludge pre-sedimentation device comprises a sedimentation tank, the bottom of the sedimentation tank is conical, the outer wall of the sedimentation tank is communicated with a water inlet pipe for feeding water, and the outer wall of the sedimentation tank is communicated with a water discharge pipe for discharging water; a guide cylinder is fixedly arranged at the bottom of the sedimentation tank in a penetrating mode, the outer wall of the top end of the guide cylinder is rotationally sleeved with a rotating ring, efficient sedimentation, intelligent monitoring and automatic adjustment discharging of sludge are achieved through the unique design of the device, the device improves the sludge treatment efficiency and precision, the difficulty and cost of manual operation are reduced, and the device is suitable for popularization and application. Meanwhile, remote monitoring and management are achieved through an intelligent control system, and the stability and reliability of the device are enhanced.

This invention discloses a parameterized-driven microsphere insulation and anti-settling structure and its monitoring method. The settlement structure of this invention includes an outer shell, a first anti-settling enclosure, a second anti-settling enclosure, a third anti-settling enclosure, an inner shell, and glass microsphere filling. The first, second, and third anti-settling enclosures are sequentially arranged inside the outer shell, and the inner shell is arranged inside the third anti-settling enclosure. The first, second, and third anti-settling enclosures are connected by bolts. The outer shell is connected to the first anti-settling enclosure, and the inner shell is connected to the third anti-settling enclosure. The gaps between the outer shell, the first, second, and third anti-settling enclosures, and the inner shell are filled with glass microspheres. This invention achieves synergistic effects of highly efficient anti-settling, ultra-low temperature stability, and vacuum maintenance capability in the pure glass microsphere insulation layer, and can be widely applied in the insulation structure of liquid hydrogen storage tanks.
