The light pressure rotator (1) is the light pressure rotator being light pressure trapped by irradiation with light and light pressure rotating about the central axis O of rotation, characterized in that a reverse torque generating section generating a torque for rotating the rotator in the direction reverse to the predetermined direction is removed from a section arranged with three blades (2) each having a first side face (3) extending in the radial direction from the central axis O of rotation, a second side face (4) facing the central axis O of rotation, a third side face (5) facing the first side face (3), a lower surface (6) intersecting the central axis O of the rotation, and an upper surface (7) facing the lower surface (6). The light pressure rotating device comprises the light pressure rotator (1), a light source (C), and an objective (condenser) lens D.

The invention discloses a water distributor for combined spiral fan-current stirring, comprising a swirl mask and an intake pipe for sewage. The invention is characterized in that: 1. four swirl masks (the diameter thereof is more than or equal to 6 m and less than or equal to 16 m), or six swirl masks (the diameter thereof is more than or equal to 12 m and less than equal to 28 m) are evenly distributed at the places with a distance of a to the center of the reactor; the apex angle of the shaft plane thereof is alpha; the side length is L, the radius of the bottom is r and the height from the bottom to the bottom part of the enclosure of an anaerobic reactor is h1. 2. the lower parts of two to four wastewater intake branches (the diameter thereof ranges from 6m to 16m) or three to five wastewater intake branches (the diameter thereof ranges from 12m to 28m) vertically go through the swirl masks respectively. The outlets of the wastewater intake branches with same diameter, same swirl-flow direction and forming an angle beta downwards with the level in the shearing direction are arranged evenly on the place of the internal wall and keeping a distance of h2 from the mask bottom to enable the swirl generated by wastewater to keep in the same direction. 3. the swirl flow direction formed by a plurality of swirl masks enables the intersection of any two swirls to keep the same flow direction. The invention has the advantages of high effective stirring and mixing, being beneficial to enhancing mass transfer in reaction zones and the existence of granular sludge, simple structure, low manufacturing and operation cost.

An AC servo-driven stirring and vibration composite nanopowder preparation ball mill, the power of which is provided by the first AC permanent magnet synchronous servo motor for stirring, the second AC permanent magnet synchronous servo motor for vibration, and the first AC permanent magnet synchronous servo motor. The servo motor meshes with the large gears at the end of the three sets of hollow stirring shaft groups through the central pinion at the output end of the reducer, and the small gear for driving the vibration eccentric shaft at the other end of the three sets of hollow stirring shafts passes through the central large gear The speed is connected with the second AC permanent magnet synchronous servo motor. The vibrating eccentric shaft of each hollow stirring shaft group is equipped with two sets of eccentric blocks. The vibrating eccentric shaft is supported on the inner hole of the hollow shaft, and the hollow shaft is welded with spiral stirring blades. Due to the use of three sets of controllable vibration stirring shaft groups, it can not only carry out stirring, but also apply vibration on the vibrating eccentric shaft, reasonably control the stirring speed and improve the stirring efficiency.
