Sectional double-shaft stirring and humidifying device

Abstract

The invention discloses a sectional double-shaft stirring and humidifying device. The device comprises a frame, wherein a stirring and humidifying area and a fluidizing area are arranged in the frame; a feed port and a discharge port are formed on the stirring and humidifying area; a water spraying device is arranged on the top of the stirring and humidifying area; a first rotating shaft and a second rotating shaft which are driven by a driving device, are arranged parallelly and rotate reversely are arranged in the stirring and humidifying area; a first paddle group is arranged on the first rotating shaft and comprises a plurality of paddle units I; a second paddle group corresponding to the first paddle group is arranged on the second rotating shaft and comprises a plurality of paddle units II; and each paddle unit I and the corresponding paddle unit II are arranged in the same radial plane, and the initial phase difference of the two paddle units is an initial angle. The device has the advantages that: a plurality of local mixing areas are axially formed by materials, so that the materials in each area are quickly backmixed and radially stirred to be quickly mixed and humidified; and blades on the shafts are arranged symmetrically, reversely and spirally, so that axial thrust and driving resistance are reduced, and a bearing and a sealing structure are difficult to damage.

Description

technical field [0001] The invention relates to a sub-area biaxial stirring humidifier. Background technique [0002] At present, the mixing equipment used for mixing and humidifying ash and water in flue gas desulfurization generally consists of two parts: a stirring mechanism and a driving device. The stirring mechanism includes two horizontal main shafts whose main bodies are located in the stirring mixing tank. A plurality of paddle groups arranged at intervals are fixed on the main shaft. The groups of blades are staggered radially, that is, the groups of blades on one main shaft extend between two adjacent groups of blades on the other main shaft. A feed port and a water inlet are provided at the feed end of the mixing tank. A discharge port is provided at the discharge end of the mixing tank. The power device includes an electric motor with a reducer and a transfer mechanism, and the power device drives two main shafts to rotate in reverse. [0003] The material i...

Problems solved by technology

[0004] The purpose of the present invention is to provide a sub-area dual-shaft stirring humidifier, which can effectively solve the problem that the existing dual-shaft stirring humidifier does not have a large amount of material stirring, resulting in uneven stirring. At the same time, the helical direction of the blade group is consistent, so that the axial thrust is large. , resulting in large driving resistance and easy damage to bearings and sealing structures
