The invention relates to a composite rotary stirring device and a working method thereof. The composite rotary stirring device comprises a tank body, wherein a driving mechanism is arranged in the center of the top of the tank body; an output shaft of the driving mechanism is fixedly connected with one end of an oscillating bar; the other end of the oscillating bar is rotatably connected with a stirring shaft; the axis of the stirring shaft is deviated from the axis of the tank body; a gear is fixed on the top of the stirring shaft and is engaged with a first inner gear ring arranged on the inner side surface of the top of the tank body; and the stirring shaft is provided with a blade mechanism. The stirring device is good in stirring effect and is good in stability in a working process.

The invention relates to the field of bubbling stirring technology, in particular to a gas explosion-preventive spiral spray pipe bubbling stirring apparatus which comprises a make-up tank, a spiral spray pipe, a gas inlet valve, a gas inlet pipe, a gas outlet valve, a discharge valve, a discharge pipe, a pressure gas inlet feed pipe, a compressed air outlet valve, an air compressor, a pressure tank gas inlet feed valve, a pressure tank, a pressure tank discharge pipe, a spiral spray pipe fixed clamp A, a spiral spray pipe fixed clamp B and a spiral spray pipe fastening device; the spiral spray pipe is arranged at the bottom side part of the make-up tank, the discharge valve is arranged at the taper bottom of the make-up tank, and the spiral spray pipe and the make-up tank are fastened by a fastening nut and a sealing pad; the diameter of the spiral spray pipe is gradually increased after entering the make-up tank, and the spiral spray pipe is spirally downward slanted along with inner arc of the make-up tank; and the make-up tank is internally provided with the spiral spray pipe fixed clamp A13 and the spiral spray pipe fixed clamp B14 which are used for fixing the spiral spray pipes. The gas explosion-preventive spiral spray pipe bubbling stirring apparatus can reduce the gas flow rate through reducing the spiral spray pipe, and can effectively prevent gas explosion phenomenon due to overhigh gas speed, and has the advantages of being long in continuously stirring time, high in efficiency, low in energy consumption, simple in structure, easy to maintain and clean, and low in cost.

The invention relates the circulating magnetic stirrer. The inductor comprises chassis, enclosing cover and upper cover, the revolution axis on the chassis is through inductor, the motor and speed reducer direct axis are connected with out end of revolution axis, the draught fan is connected with the upper cover, the permanent magnet inducer is fixed in the inducer cavity, thermal resistance windows are installed on the enclosing cover, the board insulations are on the thermal resistance windows, on the board insulation there are holes, between thermal resistance windows there are wind-guiding bar, the chassis comprises outer bottom and inner bottom, between outer bottom and inner bottom there are bars which divides the chassis to form air-out grooves, and on every air-out grooves there are inner bottom air outlet. The device has the advantages of saving energy, good heat dissipation effect and long life.

The invention relates to the technical field of bubbling stirred tank reactors. A circular inverted cone bubbling stirred tank reactor provided by the invention comprises a reaction kettle, a circular inverted cone bubbler, an inlet valve, an air inlet pipe, a discharge valve, a discharging pipe, bubbling holes, a connecting device, etc. The circular inverted cone bubbler is installed at a central part at the lower part of the reaction kettle and is connected with the air inlet pipe; the air inlet pipe is provided with the inlet valve; the bottom of the reaction kettle is connected with the discharging pipe, and the discharging pipe is provided with the discharge valve; the circular inverted cone bubbler is provided with N bubbling holes with varying directions; the external surface of the circular inverted cone bubbler is in a streamline shape, flowing resistance of a fluid is small, the moving trajectory of agitated bubbles is long, continuous stirring effects last for a long time, and high stirring efficiency is obtained; the bubbling holes are located at the lower part of a circular inverted cone, and bubbles move along an inclined downward direction at first and act on the bottom of the reaction kettle, leaving no stirring dead angle.
