The invention relates to the technical field of water treatment, and especially relates to a pipeline mixer which is applied to a flocculation deposition device and is used for fully mixing a flocculating agent with raw water. The pipeline mixer which can solve problems of low water-drug mixing efficiency and bad use reliability existing in the prior art has the advantages of simple structure, high use reliability and high water-drug mixing efficiency. The pipeline mixer which comprises a water-inlet drug-addition tube, a water-drug mixing tube and a water outlet tube is characterized in that: at least two spiral tube and impeller combinations which are promoted by the self power of a water flow are distributed in the channel of the water-drug mixing tube, and each spiral tube and impeller combination comprises a spiral tube and an impeller which is arranged on the spiral tube and is coaxial with the spiral tube; the spiral tube comprises a spiral tube body and several spiral blades fixed on the inner wall of the spiral tube body; the impeller comprises an impeller seat and several impeller blades fixed on the surface of the impeller seat; and the spiral direction of the spiral blades is opposite to the spiral direction of the impeller blades of a same spiral tube and impeller combination.

The invention discloses a drainage and stirring device for chemical experiments, which relates to the technical field of chemical experiments, and comprises a fixed frame, on which a stirring tank is rotatably installed, on which a rotating tube is rotatably installed, and on the fixed frame there is a device for driving The reciprocating lifting mechanism for the vertical movement of the stirring mechanism, the liquid discharge pipe is connected to the rotating pipe, and the liquid discharge pipe is connected with the external solution through the conveying mechanism. The chemical solution is rotated and stirred, and the reciprocating lifting mechanism set can adjust the vertical height of the stirring mechanism, so that the stirring mechanism can stir the solution at different vertical positions in the stirring tank, and the adequacy of the stirring is significantly improved. The mechanism can transport the solution to the inside of the rotating tube, and finally into the inside of the stirring tank, realizing the effect of adding the solution while stirring, and the adequacy of the solution stirring is significantly improved.

The invention discloses a reaction kettle with a cooling device. The reaction kettle comprises a kettle body, a kettle cover and a stirring device, wherein a feeding hole is formed in the upper end of the kettle body; a discharge opening A is formed in the lower end of the kettle body; the stirring device comprises a stirrer A, a transmission device, a shaft seal and a supporting seat; the stirrer A is positioned inside the kettle body; the shaft seal and the supporting seat are positioned on the kettle cover and are connected with the stirrer A by virtue of the transmission device; a thermometer well stretches into the kettle body, and the upper end of the thermometer well is fixedly arranged on the kettle cover; a thermometer is arranged in the thermometer well; the stirrer A comprises a stirring shaft A, an annular guide pipe, a stator and a rotor; the discharge opening A is connected with a tank body in which a chamber is formed by virtue of a guide pipe; and a pipeline and cooling liquid are arranged in the chamber. According to the reaction kettle with the cooling device, provided by the invention, materials can stretch into the bottom of the kettle, so that the mixing effect is improved. Moreover, according to a novel stirring device, bubbles can be reduced during stirring, the full contact among mixtures is maintained, and reaction products can be subjected to forced cooling.
