Abstract

The utility model discloses a spin-flow type air stirring device. The device is characterized in that an air inlet pipe and a rising pipe are respectively connected with a spin-flow cavity, in use, after air enters into an air ring room via the air inlet pipe and an air inlet mouth, large area circulation section in the air ring room makes the flow velocity of air stream slow down, and the kinetic pressure of part air stream is changed into static pressure. After the air stream obtains the static pressure, forming sheet shape at strip commissure and flowing into the rising pipe, because of the control of spin-flow disks in the air ring room, and the air stream rotates around a pipe axle in the rising pipe and ascends. The sheet shape air stream is ceaselessly fallen to pieces and becomes thin in the process of mixing with liquid in the rising pipe and rotary rising, forming uniform air-liquid diphasic flow body, and a pipe cap at the lower end of a dirt venting pipe can get rid of accumulation in the air ring room. The utility model avoids the defect of that big air masses generating from the running of an air beater of the prior art directly flow the outside of the pipe without mixing with liquid, improving the agitating efficiency and quality.

Description

A kind of whirlwind-type gas blender

Technical field:

The utility model belongs to the technical field of agitator, specifically a kind of whirlwind-type gas blender that relates to liquid state fermentation material in the agitated fermentation vessel.

Background technology:

The gas blender of generally using is made up of inlet pipe and upcast in the market, inlet pipe is inserted in the upcast, the axis of two tubes is parallel, the outer wall of inlet pipe is close to the inwall of upcast, the lower port of inlet pipe is positioned at upcast, lower port apart from upcast has a segment distance, and the upper port of inlet pipe is stretched out outside the upper port of upcast.During use, gas blender is inserted in the container of liquid state fermentation material, and inlet pipe is connected with gas blower, after the gas of gas blower output enters inlet pipe, flow in the upcast and form gas-liquid two-phase fluid with liquid mixing in the pipe from the lower port of inlet pipe.The density of gas-liquid two-phase fluid is less than the outer density of liquid of pipe in the upcast, the pressure of liquid in pipe is less than the pressure of the outer liquid of pipe, be subjected to the effect of both pressure reduction, manage outer liquid in upcast lower port inflow pipe, gas-liquid two-phase fluid rises in pipe and overflows the upcast upper port; The outer liquid of upcast pipe is continuously in the inflow pipe, forms behind the gas-liquid two-phase fluid again outside the discharger, so goes round and begins again, and just formed the forced convection of liquid state fermentation material in the container.Gas becomes bulk directly to enter in the upcast without refinement from the lower port of inlet pipe, a plurality of stingy groups meet and form big air mass in the process that steadily rises in upcast, can't fully mix with the liquid in the pipe and form uniform gas-liquid two-phase fluid, part large volume air mass not with the mixed outlet pipe without leave of liquid outside, reduced the stirring efficiency of gas blender.

Summary of the invention:

The purpose of this utility model is to provide a kind of improved whirlwind-type gas blender, and it makes the in small, broken bits and formation eddy flow of the gas group that enters in the upcast, improves the stirring efficiency and the quality of gas blender.

To achieve these goals, the technical solution of the utility model is: a kind of whirlwind-type gas blender, it mainly comprises inlet pipe and upcast, it is characterized in that: inlet pipe is connected with an eddy flow chamber respectively with upcast.

The utility model is owing to be connected inlet pipe respectively with upcast with an eddy flow chamber, use the liquid in the air-flow stirred vessel that rotates during use, after gas enters the compression ring chamber by inlet pipe and admission piece, compression ring indoor large-area circulation section slows down the flow velocity of air-flow, the dynamic pressure of part air-flow is converted to static pressure, air-flow obtains behind the static pressure again in the bar sealing forms laminar inflow upcast, because of about spinning disk in the ring casing of being bullied, air-flow in upcast around tubular axis line rotation rising.Laminar air-flow mixes at the liquid with upcast and rotates the refinement that constantly is broken in the process that rises, formed uniform gas-liquid two-phase fluid, gas-liquid two-phase fluid rotates on one side, rise on one side, promote its convection current and homogeneous, it is fully mixed that gas group in small, broken bits and liquid in pipe are obtained, and the utility model produces the large volume air mass and mixes the outer phenomenon of outlet pipe without leave with liquid when having avoided gas blender of the prior art to move.

Embodiment:

The utility model will be further described below in conjunction with drawings and Examples.

The utility model mainly comprises inlet pipe 1 and upcast 2, and inlet pipe is connected with an eddy flow chamber 3 respectively with upcast.The eddy flow chamber is provided with outer tube 4, interior pipe 5, upper head plate 6, bottom plate 7, spinning disk 8, admission piece 9, blow-off pipe 10 and pipe and covers 11, interior pipe passes outer tube, be connected with interior pipe with outer tube with bottom plate and form a compression ring chamber 12 by upper head plate with outer tube, interior pipe, compression ring is indoor to be equipped with some spinning disks, on the outer tube wall of interior pipe, be provided with some sealings 13, the bar sealing is close to a side of spinning disk, and corresponding one by one with spinning disk.Interior pipe in the eddy flow chamber passes outer tube, one side in eddy flow chamber is provided with admission piece and blow-off pipe, admission piece and blow-off pipe are on the same axis of compression ring chamber one side between outer tube and the interior pipe, be connected with bottom plate with upper head plate respectively, and all communicate with the compression ring chamber, the admission piece upper end links to each other with inlet pipe, and the admission piece lower end is connected with upper head plate, blow-off pipe top and bottom plate is connected, and the blow-off pipe lower end is provided with one and covers by all means.Liquid in the air-flow stirred vessel that rotates during use, promote its convection current and homogeneous, gas enters in the eddy flow chamber by inlet pipe, after gas enters the compression ring chamber by inlet pipe and admission piece, compression ring indoor large-area circulation section slows down the flow velocity of air-flow, the dynamic pressure of part air-flow is converted to static pressure, air-flow obtains to form laminar air-flow at the bar sealing again behind the static pressure, influence because of spinning disk in the ring casing of being bullied, the direction that has angle with the radius with upcast flows in the upcast, laminar air-flow mixes the gas-liquid two-phase fluid that the back forms rotation at the liquid with upcast, gas-liquid two-phase fluid rotates on one side, rise on one side, promote its convection current and homogeneous, laminar air-flow mixes at the liquid with upcast and rotates the refinement that constantly is broken in the process that rises, and has formed uniform gas-liquid two-phase fluid, thereby has improved the stirring efficiency and the quality of gas blender.Bottom, eddy flow chamber is equipped with a blow-off pipe and communicates with the compression ring chamber, opens the pipe lid of blow-off pipe lower end and can get rid of the indoor accumulation that gathers of compression ring.
