The invention discloses a self-priming stirrer in a reaction kettle, which comprises a stirring shaft, a central hole is formed in the stirring shaft, a number of suction holes connected with the central hole are formed on the upper part of the stirring shaft, and a There is an air outlet slot connected to the central hole, and the stirring shaft at the air outlet slot is fixedly connected with a centrifugal impeller. The centrifugal impeller includes an upper fixing ring, a lower fixing ring and a number of upper fixing rings, The oblique blades between the lower fixing rings; the upper fixing ring is formed with a first upper hinge plate and a second upper hinge plate protruding outward, and the lower fixing ring is formed with a first lower hinge plate protruding outward and the second lower hinge plate, the first upper hinge plate corresponds to the first lower hinge plate up and down and the first screw rod is hinged therebetween, the second upper hinge plate corresponds to the second lower hinge plate up and down and the first hinged plate is hinged therebetween Two screws. The invention has the advantages of high self-suction efficiency, uniform dispersion of gas in liquid and good mixing degree.
Description
Technical field: [0001] The invention relates to the technical field of reactors, in particular to a self-priming stirrer in a reactor. Background technique: [0002] In the process of modern industrial production, physical or chemical reactions are often required between substances, and the reactor is a container for physical or chemical reactions. Regarding the reaction substances composed of gas and liquid or gas, liquid and solid in the reactor, the traditional stirring method usually adopts heterogeneous stirring and self-priming stirring. Heterogeneous stirring During the stirring process, the size of the contact area between the gas and the liquid phase directly affects the reaction rate, which easily leads to gas dispersion and the stirring effect is not obvious. The self-priming agitator mainly uses the rapid rotation of the hollow impeller of the self-priming agitator of the reactor to form a negative pressure around the impeller while the liquid is being thrown o...
