The utility model relates to a superstrong spinning vortex paraffin-control viscosity-reduction oil increasing device, which comprises a sound wave device, a cavitation pipe and a vortex device which are connected in series, the tail end of the vortex device is connected with a spinning vortex atomization device, the spinning vortex atomization device comprises a rotational flow seat, one end of the rotational flow seat is provided with an oil inlet, the center of the other end of the rotational flow seat is provided with a rotating shaft, and the rotating shaft is rotatably connected with the rotational flow seat. A vortex nozzle is fixedly mounted at one end, facing the oil outlet, of the rotating shaft, a plurality of spraying holes are formed in the vortex nozzle, a plurality of overflowing holes are formed in the vortex seat, the oil inlet is communicated with the oil outlet through the overflowing holes, and the vortex nozzle is driven to rotate when oil passes through the spraying holes of the vortex nozzle; according to the utility model, the paraffin control and viscosity reduction effects are improved, and the oil pumping efficiency is improved.

The application discloses a new-born umbilical protrusion treatment device and method, relates to the technical field of medical devices, and comprises a ring-shaped fixing seat and a first component, wherein the first component comprises a fan beam for adapting to different protrusion sizes and adjusting the surrounding diameter, and the fan beam is rotationally connected with the ring-shaped fixing seat; through the setting of the first component, the precise adjustment of the surrounding diameter is realized through the cooperation of the fan beam and multiple components such as the engaging body, flexible adjustment and rapid locking, and the device is suitable for different specifications of small to large umbilical protrusion cases; meanwhile, the side wing fixing belt is designed by using elastic cloth and magic tape, the tightness can be flexibly adjusted according to the body type of the new-born, and it is ensured that the ring-shaped fixing seat is always attached to the skin and does not affect the respiratory movement during the treatment process; the multi-dimensional adaptive design solves the problem that the size of the traditional device is fixed and it is difficult to adapt to individual differences, and meets the treatment requirements of different new-born umbilical morphologies and changes in the disease.

The invention discloses a steel pipe flaw detection device and a flaw detection system. The steel pipe flaw detection device comprises a storage device, a conveying mechanism and a screening mechanism, the storage device is arranged at one end of the conveying device and used for stacking and pushing the steel pipes. The screening mechanism is connected with the conveying mechanism and comprises an ultrasonic detector, an electric push rod and a controller, and the electric push rod is connected with the conveying mechanism; the controller is used for receiving detection data of the ultrasonic detector and controlling the electric push rod to move, so that the electric push rod drives the conveying mechanism to incline to separate unqualified steel pipes; the controller controls the electric push rod, the servo motor and the ultrasonic detector, when the ultrasonic detector detects a damaged steel pipe and the tail end of the steel pipe passes through the ultrasonic detector, the ultrasonic detector feeds back to the controller, and the controller controls the servo motor to stop rotating and controls the electric push rod to retract at the same time, so that the supporting frame inclines; the whole process does not need manual participation, the detection efficiency is high, and the detection precision is high.
