Vertical irregular agitating blade type mixer

Abstract

The invention relates to a vertical irregular agitating blade type mixer, and aims at solving the problem of low mixing efficiency of a traditional vertical mixer. The vertical irregular agitating blade type mixer comprises a vertical mixing barrel; a feeding opening is formed in the top of the mixing barrel while a discharging opening is formed in the bottom of the mixing barrel; a rotating shaft is arranged on an axis of the mixing barrel; a plurality of agitating blades outward extend from the side surface of the rotating shaft in the radial direction. The vertical irregular agitating blade type mixer is characterized in that paddles for pushing materials are arranged on the agitating blades; the upwards inclined angles of the working surfaces of the paddles are increased according to the distance to the outer ends of the agitating blades from long to short; fixed arc-shaped baffles are arranged above the agitating blades; outer ends of the baffles are fixed on the inner wall of the mixing barrel while the inner ends of the baffles are bent in an arc shape; the inner arc-shaped surfaces of the baffles face the material incoming direction. According to the vertical irregular agitating blade type mixer, the agitating blades, the paddles and the arc-shaped baffles are matched to enable a complex three-dimensional fluidized movement track of materials in the mixing barrel to be generated, and therefore, the mixing efficiency is improved, the mixing effect is improved, and the mixing time is shortened.

Description

technical field [0001] The invention relates to a mixing device, in particular to a vertical special-shaped paddle mixer. Background technique [0002] The mixer is a device for mixing different materials. The mixing efficiency of different types of mixers is different. In solid-liquid mixing and solid-solid mixing, the basic idea is to make the solid powder to be mixed into a fluid state by rotating and agitating. Fluidization is the uniform distribution of different materials in the fluidization process. The vertical mixer generally drives the material to produce circular motion through the rotation of the central shaft to achieve fluidization, so that the components are mixed. In the fluidization process, the trajectory of the material has an important impact on the mixing efficiency. Generally speaking, the more complex the trajectory and the more it can involve all directions, the higher the efficiency of material diffusion and mixing. [0003] As the CN201124085Y pat...
