Description
Technical field
The utility model relates to fermentable apparatus field, particularly, relates to a kind of fermentor tank stirring rod.
Background technology
In bio-pharmaceuticals industry, the bacterial classification to cultivating is needed to ferment, zymotechnique carries out in fermentor tank, the process need oxygen of fermentation, therefore the oxygen needing that the air passing into cleaning in fermentor tank lacks with the fermentation of afterfermentation tank internal cause, for making the even of fermentation, disperse in the fermented liquid of the air bubble that Gu must be made to enter in fermentor tank, therefore, a whipping appts must be set in fermentor tank fermented liquid is stirred, air bubble is dispersed in fermented liquid uniformly.The volume of fermentor tank is all generally fixing, and be all generally top whipping appts being fixed on fermentor tank, the blade-section being used in stirring extend in fermented liquid, and then stirs fermented liquid.
Existing whipping appts is all generally the whipping appts adopting vane-type, its primary structure comprises stirring rod and is formed in the agitating vane in stirring rod, existing whipping appts can cause bubble in fermentation tank more in whipping process, and existing agitating vane resistance in whipping process is larger.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of fermentor tank stirring rod, easily causes more, that resistance is larger in the whipping process problem of bubble in tank body to overcome existing fermentation tank stirring device.
The technical scheme in the invention for solving the above technical problem is: fermentor tank stirring rod, comprise rotating shaft, the lower end of rotating shaft is provided with agitating vane, and the upper end of rotating shaft is provided with cross bar, the outer wall of cross bar is provided with conic convex, and the summit of described conic convex is away from cross bar; Described agitating vane comprises fixed frame, is provided with parting bead in fixed frame, and described agitating vane and shaft parallel are arranged.
The existing whipping appts for microorganism fermentation tank is all to comprising stirring rod and agitating vane usually, stirring rod is rotated under the driving of motor, drive agitating vane rotates, and then the stirring realized mixing liquid in fermentor tank, because fermentation mixed solution can produce a large amount of bubbles in whipping process, the bubble produced can swim in above mixed solution, the generation of bubble can affect the observation to mixed solution in tank body on the one hand, can affect the Blending Efficiency of Blending of mixed solution on the other hand, and existing agitating vane resistance in whipping process is larger.
Rotating shaft described in the utility model is by motor-driven rotation, the upper end of described rotating shaft specifically refers to stirring rod in use near one end of cover, the lower end of described rotating shaft specifically refers to stirring rod one end in use at the bottom of tank, the structure that described cross bar is preferably vertical with rotating shaft, described conic convex specifically refers to that one can be used in the pointed structures body that pricks a bubble, away from cross bar, the summit of described conic convex specifically refers to that conic convex summit is arranged outwardly, direct and bubble contact; Described agitating vane and shaft parallel arrange and specifically refer to that the hollow space of fixed frame is vertically placed.
The utility model by arranging cross bar in rotating shaft, the outer wall of cross bar is provided with for the conic convex that pricks a bubble, when the bubble produced in fermentor tank contacts with conic convex when moving to mixing liquid level, punctured by the summit of conic convex, avoid bubble to pile up at mixing liquid level, and then the aeration avoiding the generation of mixing liquid level is observed and mixing effect.
The utility model is by being set to non-solid structure by agitating vane, but be provided with parting bead in the fixed frame of hollow, gap is produced between parting bead, reduce the resistance of agitating vane in rotation process, and arrange due to agitating vane and shaft parallel, namely in turning direction, with mixed solution, there is larger contact area, the mixing effect of agitating vane can not be affected.
Further, the outer wall of conic convex is provided with needles.
Described needles can be used in the pointed structures body that pricks a bubble, and needles effectively can improve the efficiency that conic convex pricks a bubble, and further avoid the problem of bubble early mixing liquid level accumulation.
Further, the length of cross bar is less than fermentor tank internal diameter 50mm ~ 80mm.
Specifically refer to that one end and the fermentor tank inwall time of the rotating shaft of cross bar principle have certain gap, if the too short meeting that the length of cross bar is arranged causes can not being punctured near the bubble of fermentor tank inwall, if it is excessive that the length of cross bar is arranged, can cause bubble impact inner to fermentor tank, not easy to clean, the length of cross bar is set to be less than fermentor tank internal diameter 50mm ~ 80mm, comprehensively can prick a bubble on the one hand, the problem of the not easy to clean caused to fermentor tank inside by bubble impact can be avoided on the other hand.
Further, the upper end of rotating shaft is provided with fixed block, and the two ends of fixed block are provided with threaded hole, and one end of cross bar is provided with the outer pitch thread coordinated with threaded hole, and cross bar is fixed on fixed block with coordinating of threaded hole by outer pitch thread.
Structure like this is convenient to removing and installing of cross bar.
Further, rotating shaft is at least provided with 2 groups of agitating vanes, each group is at least provided with 3 agitating vanes, and the agitating vane of same group is at sustained height.
Arrange many group agitating vanes to be conducive to improving mixing effect.
Further, fixed frame is sector structure.
Sector structure can reduce the resistance of agitating vane to a certain extent further.
Further, the surface of fixed frame and parting bead is provided with needles.
Described needles can be used in the pointed structures body that pricks a bubble, and needles can puncture the bubble around agitating vane, avoids bubbles attached on agitating vane.
Further, rotating shaft and agitating vane adopt hard aluminium alloy to make.
Hard aluminium alloy is prior art material, has the advantage that the large quality of hard is light, can guarantee the physical strength of rotating shaft and agitating vane on the one hand, effectively can reduce weight on the other hand, and then improves stirring efficiency.
To sum up, the beneficial effects of the utility model are:
1, the utility model by arranging cross bar in rotating shaft, the outer wall of cross bar is provided with for the conic convex that pricks a bubble, when the bubble produced in fermentor tank contacts with conic convex when moving to mixing liquid level, punctured by the summit of conic convex, avoid bubble to pile up at mixing liquid level, and then the aeration avoiding the generation of mixing liquid level is observed and mixing effect.
2, the utility model is by being set to non-solid structure by agitating vane, but be provided with parting bead in the fixed frame of hollow, gap is produced between parting bead, reduce the resistance of agitating vane in rotation process, and arrange due to agitating vane and shaft parallel, namely in turning direction, with mixed solution, there is larger contact area, the mixing effect of agitating vane can not be affected.
