It is to put into all reactants in kettle to be reacted that reaction, which is closed, with the use operation of reactor, is difficult during reaction
Continue to add reactant, and part chemically reacts due to the presence reactant in course of reaction and the chemical reaction equilibrium of product
Influence, it is impossible to disposably put into all reactants, the yield of reaction product is relatively low；Due to reactor structure, lead to
The liquid reactants of pipeline midway addition are crossed, liquid reactants need to be sufficiently mixed with liquid in reaction zone by stirring,
Local reaction is easily caused, the effect of stirring reaction is poor.And on the other hand, using process for existing chemical reaction kettle
In, it is often necessary to the conciliation problem of plurality of liquid different material feed speed is faced, and the feed of existing reactor can not reconcile
The feed speed of material and simultaneously supplied for various materials, cause existing reactor to face in use greatly
Limitation.And Application No.：201520927438.4 a Chinese patent disclose a kind of reactor feeding device, it will be low
Position pipe directly goes out liquid and is changed to high-order feed tube and the surge tank discharge feed liquid with blast pipe；Increase the pressure in pipeline and regulation
The actuating range of valve, improve the control accuracy of robot control system(RCS), stabilize feed liquid flow, improve product once examine it is qualified
Rate, production cost is reduced, retrieved economic loss.But the species for supplying material is not switched for it and the adjustment of feed speed
Make a change, same Application No.：201420577103.X a Chinese patent disclose a kind of feeding structure of reactor,
The solution of above mentioned problem is not provided, in consideration of it, we can see that people are badly in need of a kind of feed of liquid reactions kettle yet
Unit, i.e., a kind of liquid reactions kettle material feed unit, it specifically has the beneficial effect that：
A kind of 1. liquid reactions kettle material feed unit of the present invention, during it can be Chemical Manufacture
Reactor improves a kind of material supply species and the adjustable feed unit of speed, is easy to regulation to chemically react, and can improve reaction effect
Rate.
2. a kind of liquid reactions kettle material feed unit of the present invention, passes through the design of feed unit, Neng Goushi
