Description

A kind of agitating device that efficient mechanical agitation is combined with air agitation
Technical field
The present invention relates to the agitating devices that a kind of agitating device, especially mechanical agitation are combined with air agitation mode.
Background technology
For stirring operation in Chemical Manufacture, metallurgy, food, medicine and other fields extensive use, being stirred not only makes multinomial body System is uniformly mixed, while can be industrial important link, the quality of mixing effect is directly with processes such as Accelerative mass transfer heat transfers Affect the production efficiency of entire industrial system.In whipping process, the close phase of disorderly degree of mixing effect and material movement It closes, material less turbulence is bigger, and material mixing is more uniform, and best hydrodynamics situation is that entire fluid layer is in stirring container A kind of state of high turbulence.
Tradition machinery formula agitating device, the lift provided using agitating paddle are made material rise overturning, reach stirring purpose. But when stirring, the material movement state in stir chamber body is not ideal enough, and the motion mode and severe degree of material are extremely difficult to Situation required by heterogeneous system;Therefore traditional agitating device stirring efficiency is not high, and mixing time is long and material mixing is uneven, The long-term stable operation that restrict production system.
The purpose of stirring is not only in that so that material is uniformly mixed, and heat and mass is also the first purpose being stirred, machine Tool stirring and mixing effect is apparent, but heat transfer efficiency is low, and air agitation lift of gas is weaker, not to high viscosity fluid mixed effect It is good;But the gas energy of flow enough takes away heat, is passed through gas or even can promote mass transfer.
Invention content
The disadvantage that the purpose of the present invention is overcome existing agitating device efficiency low provides a kind of efficiently ventilate and is stirred with machinery The agitating device being combined is mixed, with suitable for stirring suspension, the gas-liquid contact of mutually soluble liquids, solid in a liquid etc. to whether there is or not gas Steep the operating mode of no requirement (NR).
Technical solution provided by the invention is:
A kind of material high-efficiency agitating device, including stirring container, agitating paddle in stirring container inner cavity is set;Its feature exists In:The agitating device further includes the air-breather that gas is passed through from container bottom;
The air-breather includes several air admission holes for being opened in stirring container bottom, connection air admission hole and carries check valve Tracheae and by tracheae input gas air delivery device.
The stirring container includes the cylinder of vertical arrangement and upper and lower ends opening and is fastened on upper and lower ends respectively and opens The upper end cover and bottom end cover of mouth;Upper end cover is equipped with material inlet and gas outlet, in the shaft hole in upper end cover center rotationally Position shaft and motor fixing device;Being made on bottom end cover has discharge port and the air admission hole.
There are three the air admission holes, is uniformly arranged on bottom end cover bottom.
The open height of the air admission hole is the one third of bottom end cover height.
Four wall of inner cavity of the cylinder is provided with the helical baffle of connector helical form arrangement, helical baffle and cylinder Inner wall keeps certain distance;Jet hole is additionally provided on helical baffle.
The intracavity bottom of the cylinder is arranged horizontally at least one uniform device with multiple apertures, with it is evenly dispersed by The gas of air admission hole input.
Between the solid four-way connection and admission line, unidirectional stop valve, flow direction are set at solid four-way connection To flow to three-dimensional four-way connection from admission line.
The present invention operation principle be:The present invention is passed through gas on the basis of mechanical agitation, from cylinder body bottom, utilizes gas Body lift drives material to move upwards, and material is under the action of agitating paddle lift, gas climbing power and material its own gravity in cylinder Internal flip-flop movement.It is provided with the helical baffle with through-hole at four wall 5-10cm of cylinder lumen, material is by jet hole When, since runner changes, small whirlpool is stablized in formation, aggravates material less turbulence, and promoting mixing effect, (traditional agitating device leads to The baffle arranged vertically is often set in only inner barrel;The helical baffle that the present invention uses is in vertical direction and cylinder tangential direction Material movement state can be changed, mixing effect can be significantly improved).
The beneficial effects of the invention are as follows:What is provided has apparatus structure simple, and stirring efficiency is high and mixing effect is bright Aobvious advantage;Suitable for stirring suspension, the gas-liquid contact of mutually soluble liquids, solid in a liquid etc. to there is the work of bubble-free no requirement (NR) Condition, for needing heat and mass operating mode, practical function stronger.
