Combined liquid-material separation type variable-speed airflow eddy kinetic energy pulping device

Abstract

The invention discloses a combined liquid-material separation type variable-speed airflow eddy kinetic energy pulping device. The combined liquid-material separation type variable-speed airflow eddy kinetic energy pulping device mainly comprises an air inlet device, an airflow eddy breaking device and a pulp generating device. The combined liquid-material separation type variable-speed airflow eddy kinetic energy pulping device is characterized in that two conical material barrels are combined for material and liquid separation, materials are broken by means of variable-speed airflow eddy kinetic energy firstly, and then the broken materials are mixed with liquid water to generate pulp. According to the combined liquid-material separation type variable-speed airflow eddy kinetic energy pulping device, a key cross section which is in the shape of a big oval or a small oval or a big circle or a small circle is used for achieving variable-speed eddy breaking, the phenomenon of rotary cakes is prevented, breaking efficiency is improved, constant-speed transition of the broken materials is achieved, the material filtering speed is increased, and blockage-free conveyance and rapid broken material mixing and stirring are combined; through smooth and fillet transition of the air inlet device, airflow movement resistance is reduced, and energy consumption is reduced; airflow pressurizing and accelerating are achieved through the design of a diameter difference value; through the arrangement of a broken material filtering device, screening of the broken materials is achieved, and the broken materials are prevented from getting stuck; water is added, air is exhausted and big foreign matter is prevented from falling into the device through a latticed water inlet provided with rectangular holes.

Description

technical field [0001] The invention relates to a combined material-liquid separation variable-speed airflow vortex kinetic energy pulping equipment, in particular to a kind of variable-speed swirl crushing and prevention of "swirl flow" through the key cross-section of large ellipse, small ellipse, large circle and small circle. Cake phenomenon, improved crushing efficiency, uniform transition of crushed materials, speed-up of filter materials, non-clogging conveying and rapid mixing of crushed materials. The air duct and the air intake duct of the small material cone generate low-energy-loss circulation, and the smooth and rounded transition of the intake device reduces the resistance to air movement, reduces energy consumption, and the design of the diameter difference realizes airflow pressurization and speed-up, and filters through debris The device realizes crushed material screening and prevents crushed material from clogging, and realizes adding water, exhausting air a...
