Abstract

The invention relates to the development of a pneumatic stirring machine which adopts the air flow to replace the current to push stirring blades during the biological fermentation process. The pneumatic stirring machine for the biological fermentation is characterized by including the study on the 'pneumatic stirring machine which utilizes the biologically-fermented compressed sterile air flow kinetic energy to drive a stirrer. By adopting the pneumatic stirring machine for biological fermentation, external power does not need to be used as the power in the whole process, so that about 50% of the comprehensive energy consumption in the biological fermentation can be reduced; and the pneumatic stirring machine can completely solve the problems due to high energy consumption and high pollution in the biological fermentation by being used in match with a 'full-automatic control defoaming backflowing device'of the same inventor who acquires the national patent certificate of the 'full-automatic control defoaming backflowing device'.

Description

The biological fermentation Pneumatic blender

Technical field

The present invention relates to the biological fermentation field, the biological fermentation development of airflow kinetic energy stirrer (hereinafter to be referred as Pneumatic blender) that particularly relates to required compression sterile air airflow kinetic energy instead of electr ic motor driving stirring rake in a kind of applying biological zymotechnique that consists of one of environmentally friendly bio-reactor two large main equipments of low power consuming.

Background technology:

The high energy consumption high pollution is the crucial general character difficult problem of worldwide industry in biological fermentation production.Wherein, be used for to drive stirring rake and carry out the required energy consumption of fermentative production, severally account for nearly 50% of the comprehensive power consumption of biological fermentation.Substitute the technology of stirring rake although occur in recent years in research and development and using in the gentle mixed mode of gas lift, since in the difference of fermentation category individual character and the fermenting process to the shearing of gas-liquid flow and gas-liquid molecular grouping, melt the specific demand of the mechanism such as mixed, the main flow that the stirring-type fermentation is still produced as biological fermentation, ratio in whole biological fermentation primary device is up to more than 95%, and the biological fermentation high energy consumption is the Major Difficulties that domestic and international fermentation industry is endeavoured to capture always.

Summary of the invention:

Purpose of the present invention is to capture difficult point of the prior art exactly, improve the internal configuration of gas-liquid flow and streams in the biological fermentation process, change the passage that sterile air leads to reactor, replace stir shaft with ventpipe, can replace electric energy with the driven by motor stirring rake with the pressure air flowing in the input reactor, reach the operating mode that both fully keeps traditional stirring rake, directly saved again electric energy, fundamentally change biological fermentation high energy consumption present situation.The full automatic control that has obtained national inventing patent with the inventor hinders the environmentally friendly reactor of low power consuming that the mating reaction of foam reflux consists of, and can fundamentally crack the difficult problem of biological fermentation high energy consumption, high pollution.

The present invention realizes by following technological method:

1, a kind of airflow kinetic energy of can utilizing replaces electric energy to drive the Pneumatic blender of the innovation of stirring rake.It is characterized in that the intasome that three pipe fittings that are actively coupled by pulley and arm form, wherein upper, lower tube is combined into an integral body with the axis inlet pipe is fastening respectively, middle pipe is movable rotating wheel, built-in jet orifice and propelling movement hinge, outer with by fastening with the spider of the blade that is subjected to the whirlpool sail, air-flow promotes impeller by blade under unsteady flow and the afterburning effect of injection, drive blade.Pneumatic blender ties up to fluid dynamic energy and drives on oar device (by inventor's separate case application national inventing patent) basis innovation of needs research and development of making the large resistance Pressure Vessel agitating function of kinetic energy with air-flow for adapting to, it connects by track up and down and changes pulley into, increase afterburning design and drag reduction and protected the power chute, increased controllable-thrust.

2, a kind of band that can utilize the eddy current that foam reflux (obtaining national inventing patent by the inventor) the backflow gas-liquid flow ring stirring rake that disappears forms is subjected to the blade of whirlpool sail function.Can directly accept the vortex thrust that formed by the backflow lance ejection, thereby reduce the resistance that is formed by static pressure and dynamic pressure in the reactor, guarantee that Pneumatic blender runs well under low-yield promotion.

3, a kind of can guarantee air-flow during by impeller thrust affect shock resistance and increase and prevent thrust and according to the reinforcing station of in bead filler pipe jacking section and chute, playing afterburning effect of L.L pipe (obtaining national inventing patent by the contriver) principle innovation invention.

4, a kind of and foam return channel multi pack that disappears utilizes the self-con-tained unit of foam return channel automatic control function control Pneumatic blender rotating speed of agitator that disappears, and regulates thereby reach the automatic equalization that stirs with the foam backflow optimum value that disappears.

Specific implementation method:

1, Pneumatic blender of the present invention is by forming such as lower member:

1. position rotating storehouse (Fig. 2-1)

The spin storehouse is and ventpipe indentical tube shape structure, and the upper end is fastening with flange and ventpipe, and body bottom evagination, section are and collude shape (Fig. 3-1), built-in band bearing chute (Fig. 3-2).

2. pneumatic stirring storehouse (Fig. 2-2)

The stir storehouse main body is and ventpipe indentical tube shape structure, is weldingly connected (Fig. 3-5) by respective angles with some distortion thin plates between core pipe (Fig. 3-4) and supervisor's inwall, laterally forms runner.Supervisor's outer wall and band spider sleeve pipe welding (Fig. 2-4), agitating vane is integral formula structure (Fig. 4) with embedded two-sided weldering and spider.

3. be used to slide storehouse (Fig. 2-3)

Slide storehouse main body and ventpipe indentical tube shape structure, top is provided with guard shield, and cover internal card ear (Fig. 3-8) is connected into movable whole with stir storehouse pipe core draw-in groove, and cover is built-in with slip rail and afterburning station.

4. be subjected to whirlpool sail blade

Determine the matrix paddle board that best thrust surface para-curve is made in the corresponding position, blade blade face that makes by processing requirement by processing parameter.

2, " full automatic control disappear foam return channel " two devices of the present invention and the existing independent intellectual property right of the inventor are in parallel, and use can be received low power consuming environment dual function synchronously.

The invention effect:

1, realized replacing the agitator motor power consumption with airflow kinetic energy, biological fermentation has comprehensively been consumed energy reduce nearly 50%.

2, thoroughly eliminate the noise pollution that causes because of agitator motor, eliminated the potential safety hazard that the agitator belt pulley of high power motor and high-speed cruising brings.

3, be used with the full automatic control foam return channel that disappears, both optimized equipment performance, comprehensively realized again environmental protection, energy-conservation double goal.
