Description
Technical field
The utility model relates to the diluter of a kind of concentrated sulfuric acid, red fuming nitric acid (RFNA), concentrated hydrochloric acid.
Background technology
Industrial three acid often will be diluted by teaching, scientific research, production laboratory, and promptly the concentrated sulfuric acid, red fuming nitric acid (RFNA), concentrated hydrochloric acid have certain danger in dilution, red fuming nitric acid (RFNA), concentrated hydrochloric acid have " mist ", have powerful excitant, special diluting concentrated sulfuric acid is wanted SC, splashes on the skin abnormally dangerous.Now Chang Yong dilution process is that three acid are gently poured in the beaker along glass bar, and constantly stirs heat radiation with glass bar.Though this method has certain science, has obvious defects:
1, operation must be careful, and one has accidentally, and the concentrated sulfuric acid promptly might spill.
2, method clumsiness, and efficient is low.
3, room air is polluted in " acid mist " diffusion easily, sucks staff's respiratory tract.
4, the diluted concentration controllability is not high.
Summary of the invention
Technical problem to be solved in the utility model provides the three sour diluters that a kind of easy to operate, diluted concentration controllability is strong, danger is little, efficient is high.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this three sour diluter, comprise that one has the glass container of scale, be provided with the baffle that a sidewall contains the water conservancy diversion aperture in the container, one bottom has the stirring rod of disc expansion section and inserts in the baffle, the bottom of baffle is fixed with the holder edge that can hold stirring rod, container be provided with one with the fixing supporting plate of baffle, fix a little bowl on the supporting plate, little bowl is gone up the teabowl with a cover lid, supporting plate, the water conservancy diversion aperture is all arranged at the bottom of little bowl, the bowl lid, all there is the through hole that can supply the glass bar end to stretch out at the center of supporting plate, and little bowl middle part projection has the through hole that can supply the glass bar end to stretch out on the lug boss.Described stirring rod can be formed with the disc base plate is bonding by excellent always.Can establish the movable little bowl of a height a little less than little bowl height in described little bowl, movable little bowl bottom has the water conservancy diversion aperture, and there is lug boss the centre, and the through hole that can supply the glass bar end to stretch out is arranged on the lug boss.
Compared with prior art, advantage of the present utility model is:
1, science reasonable in design, easy-to-operate, it had both finished dilution function, can serve as simultaneously the memory of depositing standby diluted acid again uses, liquid container indicates this degree of volume, be equipped with and get the liquid tap and can make large beaker and use, more large beaker of original requirement and big volume narrow-mouthed bottle are greatly reduced, can be used as basic tool and use;
2, can reduce " acid mist " diffusion, avoid air pollution;
3, the dilute strength controllability is strong, and high efficiency is diluted, stores, takes very convenient, can be widely used in teaching, scientific research, laboratory etc., is desirable dilution instrument.

Fig. 2 is another structural representation of baffle.
Fig. 3 is a structural representation two of the present utility model.
Fig. 4 is an operation chart.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, of the present utility model three sour diluters are a glassware, and it mainly is formed by combining by the liquid container 6 that indicates graduation mark, little bowl, stirring rod 1, supporting plate 5 and baffle 10.Wherein the volume of liquid container 6 is bigger, can adorn one in its sidewall bottom and get liquid halter 9, with convenient for taking liquid.If deposit rare nitric acid, this container should be made brown bottle, reduces light transmission, prevents that rare nitric acid from decomposing.
Stirring rod 1 is made of with the disc base plate 7 that is bonded in straight rod bottom rod always, according to manufacture craft, but also global formation of this stirring rod.Wherein the diameter of disc base plate will be slightly smaller than the internal diameter of baffle.
Supporting plate 5 is a disc, and the edge of dish upwarps, and in the bottom of dish one flange is arranged, and this flange can be just matches with the peristome internal diameter of container.On the contrary, also this flange can be changed system into groove, the peristoma of container is just inserted in the groove.There is a through hole that can supply the stirring rod end to stretch out at the center of supporting plate 5, and the bottom symmetry of supporting plate has eight water conservancy diversion apertures 11.
Little bowl comprises fixing little bowl 3 and movable little bowl 4, and all there is a lug boss centre of little bowl, is shaped on central through hole on the lug boss, can stretch out for the stirring rod end.Little bowl bottom all is shaped on several water conservancy diversion apertures, and the height of wherein movable little bowl is lower than fixing little bowl slightly, and the water conservancy diversion aperture is slightly little.
During assembling, earlier stirring rod 1 is inserted in the baffle 10, blocks stirring rod 1 in the baffle bonding holder in bottom along 8 then, stirring rod 1 is placed in the baffle 10; Then little bowl is placed on the supporting plate 5 and with supporting plate is bonding to be integral, be inserted in the baffle 10 of band stirring rod 1 again, with baffle and supporting plate, little bowl of bonding being integral; At last supporting plate 5, little bowl, baffle integral body are placed on the container 6, put movable little bowl 4 and get final product with bowl lid 2.For the enhanced leaktightness effect, supporting plate and container, bowl lid and being in contact with one another of little bowl all are processed into ground between face.
The using method of this diluter is as follows: 1, calculated the volume of the water of needs according to desired concn, the water of the desired body product of packing in container; 2, on container, place the dilution tray portion, prepare dilution; 3, pour acid solution (had better not pour in the hole that baffle and stirring rod be nested) in little bowl, at this moment acid solution will drain on the baffle by aperture from bowl, lead in the water along the baffle sidewall; 4, spur the stirring rod stirring simultaneously and make dilution evenly, improve radiating rate.
And should not be too fast when dilution, the disposable concentrated sulfuric acid of pouring into is too much unsuitable, otherwise can cause the liquid in containers bumping to be not easy to heat radiation, and glassware is burst.Can constantly cover the bowl lid in the dilution, seal acid mist as far as possible, wait for a moment quietly, pour concentrated acid again into.During the dilution concentrated sulfuric acid,, the little bowl of activity can be set on the fixing little bowl for avoiding the liquid bumping because heat release is too many.Because movable little bowl small opening is less, the speed of bleeding is slower, is convenient to slowly control.Because " acid mist " is more, bleed with fixing little bowl when dilution concentrated hydrochloric acid, red fuming nitric acid (RFNA), because of fixing little bowl small opening is bigger, speed is very fast, and in time covers the bowl lid, in order to avoid " acid mist " blows out.
The bowl lid 2 of this diluter also can directly be adhesively fixed with fixing little bowl 3, in do not establish movable little bowl, fall sour mouthful and open one at the bowl lid, and join a glass plugs 12 (as shown in Figure 3), the acid mouth that falls during dilution locates to put a funnel, to guarantee to topple over the safety of concentrated acid, acid mist is enclosed in the container must not overflow (as shown in Figure 4).
