Abstract
The utility model discloses a distillation head capable of realizing a plurality of operations. The distillation head comprises a steam pipe, a water distribution pipe and a connecting pipe, wherein the steam pipe is provided with an upper port and a lower port; the upper end of the water distribution pipe is provided with the upper port communicated with a condenser; the lower end of the water distribution pipe is communicated with a branch pipe which is used for liquid of the water distribution pipe to flow out and is provided with a control valve I; the outer end of the branch pipe is provided with an outer port; the connecting pipe is used for communicating the upper end of the steam pipe with the upper end of the water distribution pipe; and a reflowing pipe for communicating the lower end of the water distribution pipe with the steam pipe and is provided with a control valve II is arranged below the connecting pipe.
Description
Technical field
The utility model relates to a kind of still head.
Background technology
Fig. 1 is common still head, and Fig. 2 is the 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, need change corresponding instrument when carrying out different operating, have increased the complexity of operating process.Present 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, the bumping phenomenon appears sometimes.Common still head or Ke Shi still head all are 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 the distillation procedure failure.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of still head of realizing multiple operation.
In order to solve the problems of the technologies described above, the technical solution of the utility model 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 that is communicated with condenser, the lower end of distributive pipe and the arm connection with the control valve I of flowing out for distributive pipe liquid, 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 the tube connector below arranges the return duct with the 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 directly is communicated with distil container or is communicated with distil container via rectifying column again.
Above-mentioned still head, described distil container are cucurbit, and condenser is condenser pipe.
Above-mentioned still head, described arm and return duct integral body are straight tube, and the external port of arm is downward-sloping, the connection of reinforcing usefulness is set between arm and the distributive pipe supports.
Above-mentioned still head, the caliber of described arm and return duct is little than other caliber.
During common distillation procedure, make the control valve II be in closed condition, the control valve I is in open mode, can realize common distillation procedure, has the function of common still head and Ke Shi still head.When dividing the water operation, make the control valve II be in all the time closed condition, the control valve I is initially located in closed condition, azeotropic cut cooling tails accumulates in distributive pipe and layering, after running up to suitable height, opens lower floor's water the control valve I, water is put into receiving vessel by arm, and cycling gets final product, and has the function of water knockout drum.After connecting condenser pipe, air intake duct, vavuum pump and vacuum Receiver, can realize the function of vacuum distillation apparatus.The utility model can also be realized 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 the control valve I, cut is put into receiving flask, in this course, if bumping occurs, the liquid foam is broken through the top of gas channel, then opens the control valve II, by return duct bumping liquid is put back in the distil container, again be back to the cut temperature, in this process, the pipeline that also bumping is caused pollutes all have been cleaned, then the closed control valve II repeats the collection operation of cut.In addition, by the aperture of control control valve I and control valve II, can regulate reflux ratio with the collection of control cut.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is common still head.
Fig. 2 is the Ke Shi still head.
Fig. 3 is water knockout drum.
Fig. 4 is vacuum distillation apparatus.
Fig. 5 is structural representation of the present utility model.
Fig. 6 is a kind of vacuum distillation apparatus.
Fig. 7 is another kind of vacuum distillation apparatus.
Among the 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.
The specific embodiment
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 that is communicated with condenser, the lower end of distributive pipe and arm 4 connections with control valve I 5 of flowing out for distributive pipe liquid, 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 the tube connector below arranges the return duct 6 with control valve II 7 that is communicated with distributive pipe lower end and steam pipe.
Particularly, the lower port of described steam pipe directly is 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 integral body are straight tube, and the external port of arm is downward-sloping, the connection of reinforcing usefulness is set between arm and the distributive pipe supports 8.
Particularly, the caliber of described arm and return duct is little than 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 easily advantage of simple in structure, economy.
