The present application relates to the technical field of sludge treatment, in particular to a sludge suction dredging device for landscaping and a using method thereof. The device comprises a suction machine and a chassis connected with the liquid inlet end of the suction machine, the inside of the chassis is provided with a suction port assembly for regulating the size of the liquid inlet, the suction port assembly at least comprises two symmetrical elastic rods fixedly connected with the inner wall of the chassis, and the opposite ends of the two elastic rods are rotatably connected with a disturbance plate, the two symmetrical disturbance plates are rotatably arranged in the inside of the chassis, the compression and rebound force generated in the inside of the elastic rod resists the "eight" shape formed by the rotation of the surface of the two symmetrical disturbance plates, so that the flow rate of the sludge is accelerated when the sludge passes through the liquid inlet, and the impact force generated when the sludge enters the liquid inlet opened in the side wall of the chassis is buffered, the rotation shaft of the disturbance plate is connected with an auxiliary disturbance assembly, the elastic rod slides in the inside of the chassis, pushes the disturbance plate to rotate in the inside of the chassis, and regulates the size of the liquid inlet of the chassis.

The present application relates to a method for preventing sticky sludge from expanding and blocking a denitrification system, characterized in that a plate-and-frame tank is arranged between a secondary sedimentation tank and a filter tank to intercept sticky sludge in an expanded state; the plate-and-frame filler adhering to the sticky expanded sludge is collected for air flushing and chemical micro-stimulation, growth factors generated by promoting the expansion of the sticky sludge are returned to a biochemical tank, the hydraulic retention time of the biochemical tank is shortened, the expansion of the sticky sludge is promoted, and then physical separation of the sticky sludge is performed, so that the treatment cycle of the sticky sludge expansion is reduced, and a simple, energy-saving, economical and easy-to-control water treatment process is provided for relieving the sticky sludge expansion.

The utility model discloses a kind of waste chip cleaning devices for numerical control turning and milling composite machine tool, including bearing auxiliary assembly and recycling processing mechanism, the middle part inside of bearing auxiliary assembly is provided with the main cleaning component of bolt assembly, the inside of one end of bearing auxiliary assembly is provided with the recycling processing mechanism of bolt sleeve joint, the recycling processing mechanism includes bolt base, empty slot shell, end-to-end frame, isolation plate, non-woven fabric cover, evacuation fan, rotary motor, rotary stick, flexible hammer and cleaning box;The waste chip cleaning device for numerical control turning and milling composite machine tool utilizes rotary motor in the both end side of empty slot shell, so that, rotary motor carries out output power according to the need in time, let rotary stick and flexible hammer carry out rotation and then beat non-woven fabric cover, so that the waste attached on non-woven fabric cover falls into cleaning box due to the power of impact, to be able to timely alleviate jamming phenomenon, keep efficient recycling cleaning effect.
