Description
Technical field
The utility model belongs to bioengineering field, and in particular to a kind of controllable aperture reactor spray head.
Background technique
The research and development of bioengineering enlarged experiment and the related importance of industrialization production success are exactly the design of spray head.It is logical
In normal situation, it will be installed two spray heads in bioreactor, but seed bioreactor only one spray head.It is present for
There are two types of the spray heads used: drilling rod and injection stone.Drilling rod generates big bubble and low kLa, smaller to the shearing force of cell,
And it sprays stone and generates small bubble and high kLa so that greater number of oxygen can be delivered under same airflow rate into carefully
In born of the same parents' suspension.The change of oxygen concentration by kLa, bubble average saturation oxygen concentration, the oxygen concentration of dissolution and any deposit
(OUR) is controlled in the oxygen absorption of cell.Us can be helped to estimate the OUR of bioreactor the understanding of kLa, needed for prediction
The time of the carbon dioxide level of the flow velocity and prediction dissolution of oxygen and progress curve.So regulation Kla is adjustment biological respinse
The one of the best way of device.The needs of Kernel-based methods and the ability of spray head, process engineer determine the excellent of bioreactor
Change configuration.According to process OUR needs, reactor, which can be set, uses different number of drilling rod spray head or different number of spray
Penetrate stone, or even different number of drilling rod and injection jewel can merge using the Kla for removing adjustment reactor.Due to two kinds of sprays
Head bubble size be all it is fixed, all have no idea during the cultivation process by adjusting Air Bubble Size, thus test or produce
Kla in the process can not change, and only can just adjust and reform after the completion of experiment or production batch, influence conventional efficient and production effect
Benefit.
Summary of the invention
The purpose of the utility model is to provide a kind of controllable aperture reactor spray heads.
The utility model is practiced by the following technical programs:
The controllable aperture reactor spray head of the utility model, including the tracheae in nozzle housing and shell, after tracheae

Connecting rod in body is connected, and the other end of connecting rod is connected with the button for being set to shell right end.
It is preferred that the groove of each aperture control device is uniformly distributed on jet tube wall, and it is located at the same air jet pipe
On section.
It is preferred that the groove of each aperture control device is 3.
It is preferred that being equipped with slideway in the groove, the piece that supports is stuck in slideway, so that supporting piece can be in a groove
It slides along slideway, is adjusted so as to the size to air hole or ventilating groove in groove, adjust from air hole or breathe freely
The air-flow size that slot passes through, to change ventilation form and ventilatory effect.
It is preferred that the rear end of the central shaft rod is connected through connecting rod with the reciprocal motor in nozzle housing, reciprocal motor and letter
Number reception device is connected, and signal receiving device is given by external signal control device emission instruction signal, to control past
The switch and speed of multiple motor, to control central shaft rod.
It is preferred that the side of the air hole or ventilating groove groove.
The utility model can drive support rod to move slightly by central shaft rod, support piece and slide, to breathe freely in adjusting grooves
The size of hole or ventilating groove changes ventilation form and ventilatory effect, adjusts Air Bubble Size, changes in experiment or production process
Kla improves conventional efficient and productivity effect.
