Abstract
The invention discloses a liquid stirrer for chemical production, which comprises a stirring shaft which allows gas to be introduced, and a power device. According to the invention, nitrogen is allowed to be introduced into the stirrer during using, and oxygen in the liquid is discharged, so the technical problem of inadequate oxygen removal during chemical production is solved.
Description
Technical field
The present invention relates to a kind of liquid stirrers, especially for the liquid stirrers in the Chemical Manufacture.
Background technology
In Chemical Manufacture, it is addings of not wishing to have air that a lot of chemical reactions are arranged, because airborne oxygen can react with some chemical composition, thereby reduced the quality of finished product after the reaction, therefore, we need be toward supplying nitrogen in the liquid in the reactive tank, drive away the oxygen of the inside, in the process of supplying nitrogen, reactive tank is stirred, the one, can remove oxygen more fully, the 2nd, can allow compound fully react.For example, in the process of producing epoxy resin, need be miscible ECH (epoxychloropropane) and BPA (bis-phenol base propane), in this process, need remove the oxygen of the inside toward supplying nitrogen in BPA and the ECH mixture.Generally speaking, employing be with a wireway, be passed into mixed liquor bottom, supplying nitrogen.But so normally can cause removal oxygen insufficient.
Summary of the invention
The invention provides the liquid stirrers that a kind of chemical industry is used, can solve and remove the inadequate technical problem of oxygen.
A kind of liquid stirrers that is used for Chemical Manufacture, the power set that comprise shaft and stirring vane and can drive the shaft motion, stirring vane is positioned at an end of shaft, and shaft is for can at one end feeding the hollow tubular object that the other end of gas is discharged.
Power set link to each other with shaft, the motion of driving shaft, stirring vane is positioned at an end of shaft, and be in below the liquid level, feed nitrogen at the shaft other end, nitrogen just can be discharged from a liquid level end once, and shaft is stirring liquid in addition, the nitrogen that enters liquid will be stirred, thereby can improve the efficient of deoxygenation gas and can remove oxygen in the liquid more fully.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the schematic diagram of the liquid stirrers used of a kind of chemical industry
The specific embodiment
Shown in Figure 1,5 is reactive tank, power set 1 link to each other with shaft 2 by transmission device 3, and drive shaft 2 motions, the liquid level that stirring vane 6 is positioned at an end of shaft 2 and is positioned at reactive tank 5 is below 4, shaft 2 is a hollow structure, can discharge from the end feeding nitrogen of shaft 2 and from the other end that is positioned in addition below the liquid level.
When in running order, power set 1 drive shaft 2 and stirring vane 3 stirs below liquid level, simultaneously shaft 2 are fed nitrogen, and nitrogen will be emerged with next end from the liquid level of shaft, the nitrogen of emerging can form bubble below liquid level, and can rise.The nitrogen bubble that rises can be stirred blade and smash, and forms very tiny bubble, and enters in the liquid uniformly along with stirring the liquid stream that forms, thereby has reached than using wireway directly toward sending nitrogen better effect below the liquid level.
The present invention can also hole shaft 2 on the tube wall of the end that stirring vane 6 is arranged, make the nitrogen that feeds to discharge from these holes, has further increased the efficient of deoxygenation gas.
Claims (2)
1. liquid stirrers that is used for Chemical Manufacture, the power set that comprise shaft and stirring vane and can drive the shaft motion, stirring vane is positioned at an end of shaft, it is characterized in that described shaft is for can at one end feeding the hollow tubular object that the other end of gas is discharged.
2. the liquid stirrers that is used for Chemical Manufacture according to claim 1 is characterized in that, described shaft has the hole of can supplied gas discharging on the tube wall of the end that stirring vane is housed.
