The distilling head comprises a steam pipe, a water distributing pipe and a connecting pipe; the steam pipe is provided with an upper port and a lower port; the upper end of the water distributing pipe is provided with the upper port connected with a condenser; the lower end of the water distributing pipe is communicated with a branch pipe with a control valve I, which is used for the flow-out of liquid of the water distributing pipe; the outer end of the branch pipe is provided with an external port; the connecting pipe is used for communicating the upper end of the steam pipe and the upper end of the water distributing pipe; and a back flow pipe with a control valve II, which is communicated with the lower end of the water distributing pipe and the steam pipe, is arranged below the connecting pipe.
Description
technical field
The present invention relates to a kind of still head.
background technology
Fig. 1 is common still head, and Fig. 2 is Ke Shi still head, and Fig. 3 is water knockout drum, and Fig. 4 is Claisen distilling head.They only have a kind of function separately, in the time carrying out different operating, need change corresponding instrument, have increased the complexity of operating process.Current Claisen distilling head is complicated monolithic construction, and manufacturing cost is high, and certain any damage will cause the damage of whole instrument.
In addition, in the process of distillation, there is sometimes bumping phenomenon.Common still head or Ke Shi still head are all difficult to the destruction of opposing bumping, and the liquid foam of bumping is easy to break through the top of gas channel, enters downward-sloping condenser pipe and polluted product, cause distillation procedure failure.
summary of the invention
The technical problem to be solved in the present invention is to provide a kind of still head of realizing multiple operation.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of still head, comprise steam pipe, distributive pipe and tube connector, steam pipe has upper port and lower port, the upper end of distributive pipe has the upper port being communicated with condenser, the lower end of distributive pipe and the arm with control valve I flowing out for distributive pipe liquid are communicated with, the outer end of arm has external port, and tube connector is used for being communicated with steam pipe upper end and distributive pipe upper end, and tube connector below arranges the return duct with control valve II that is communicated with distributive pipe lower end and steam pipe.
Above-mentioned still head, the lower port of described steam pipe is directly communicated with distil container or is communicated with distil container via rectifying column again.
Above-mentioned still head, described distil container is cucurbit, condenser is condenser pipe.
Above-mentioned still head, described arm and return duct entirety are straight tube, and the external port of arm is downward-sloping, and the connection support of reinforcing use is set between arm and distributive pipe.
Above-mentioned still head, the caliber of described arm and return duct is little compared with other caliber.
When common distillation procedure, make control valve II in closed condition, control valve I, in open mode, can realize common distillation procedure, has the function of common still head and Ke Shi still head.While dividing water operation, make control valve II all the time in closed condition, control valve I is initially located in closed condition, the cooling tails of azeotropic cut accumulates and layering in distributive pipe, after running up to suitable height, opens lower floor's water control valve I, water is put into receiving vessel by arm, and cycling, has the function of water knockout drum.When connecting after condenser pipe, air intake duct, vavuum pump and vacuum Receiver, can realize the function of vacuum distillation apparatus.The present invention can also realize anti-bumping, wait to operate and it's time to collect cut closed control valve I and control valve II, cut accumulates in distributive pipe, run up to and suitably highly open control valve I, cut is put into receiving flask, in this course, if there is bumping, liquid foam is broken through the top of gas channel, opens control valve II, by return duct, bumping liquid is put back in distil container, again be back to cut temperature, in this process, the pipeline also bumping being caused pollutes all have been cleaned, then closed control valve II, repeats the collection operation of cut.In addition, by controlling the aperture of control valve I and control valve II, can regulate reflux ratio to control the collection of cut.

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
Fig. 1 is common still head.
Fig. 2 is Ke Shi still head.
Fig. 3 is water knockout drum.
Fig. 4 is vacuum distillation apparatus.
Fig. 5 is structural representation of the present invention.
Fig. 6 is a kind of vacuum distillation apparatus.
Fig. 7 is another kind of vacuum distillation apparatus.
In figure: 1 steam pipe, 2 distributive pipes, 3 tube connectors, 4 arms, 5 control valve I, 6 return ducts, 7 control valve II, 8 connect support, 9 thermometers, 10 cucurbits, 11 receiving flasks, 12 vacuum Receivers, 13 air intake ducts, 14 condenser pipes, 15 rectifying columns.
Detailed description of the invention
As shown in Figure 5, a kind of still head, comprise steam pipe 1, distributive pipe 2 and tube connector 3, steam pipe has upper port and lower port, the upper end of distributive pipe has the upper port being communicated with condenser, and the lower end of distributive pipe and the arm with control valve I 54 flowing out for distributive pipe liquid are communicated with, and the outer end of arm has external port, tube connector is used for being communicated with steam pipe upper end and distributive pipe upper end, and tube connector below arranges the return duct with control valve II 76 that is communicated with distributive pipe lower end and steam pipe.
Particularly, the lower port of described steam pipe is directly communicated with distil container or is communicated with distil container via rectifying column 15 again.
For chemical experimental instrument equipment: described distil container is cucurbit, and condenser is condenser pipe.
Particularly, described arm and return duct entirety are straight tube, and the external port of arm is downward-sloping, and the connection support 8 of reinforcing use is set between arm and distributive pipe.
Particularly, the caliber of described arm and return duct is little compared with other caliber.
Adopt above-mentioned still head can carry out multiple operation, and need not change, convenient and practical.
Fig. 6 shows the vacuum distillation apparatus that adopts above-mentioned still head, steam pipe upper port place inserts thermometer 9, the lower port of steam pipe and distil container (cucurbit 10) are communicated with, the upper port of distributive pipe connects condenser (condenser pipe 14), the external port of arm connects receiving vessel (receiving flask 11) by vacuum Receiver 12, upper end of condenser and vacuum Receiver all connect air intake duct 13, and air intake duct connects vavuum pump.Fig. 7 with Fig. 6 difference is: the lower port of steam pipe is communicated with distil container via rectifying column 15 again.Air intake duct is preferably inhaling hose.Vacuum distillation apparatus is compared with the vacuum distillation apparatus shown in Fig. 4, is formed by assembling parts, when a certain parts are damaged, only needs to change corresponding parts, has simple in structure, economy advantage easily.
