Abstract
The utility model relates to a laboratory waste fluid treating device. A waste alkali lye cylinder and a waste acid liquor cylinder are respectively fixed at the two sides of the upper part of an iron support through iron clamps, a soft plastic conduct pipe at the bottom of the waste alkali lye cylinder is connected at the upper part of an acid and alkali neutralization treating cylinder, a soft plastic conduct pipe at the bottom of the waste acid liquor cylinder is connected with a glass conduct pipe, the other end of the glass conduct pipe is positioned at the lower part of the acid and alkali neutralization treating cylinder, a waste liquid output soft plastic conduct pipe is arranged at the bottom of the acid and alkali neutralization treating cylinder, and a flow velocity adjusting switch is arranged on the soft plastic conduct pipe. The waste fluid treating device provided by the utility model embodies the reutilization of resources, and effectively controls the pollution caused by the waste liquid in the laboratory; the principle for treating the waste liquid is the important knowledge in the chemistry of the junior middle school, namely, the neutralization reaction between acid and alkali, thus not only ensuring students to study the neutralization reaction in order to apply, but also ensuring students to feel the importance of studying the chemistry.
Description
Technical field:
The utility model relates to a kind of laboratory liquid waste treating apparatus.
Background technology:
Now the student experimenting of junior middle school chemistry can be used the very strong solution of alkalescence such as acid very strong solution such as dilute hydrochloric acid, dilute sulphuric acid, rare nitric acid and sodium hydroxide, potassium hydroxide, yellow soda ash, salt of wormwood in a large number, experiment back students' union directly arrived water drain with discharging of waste liquid in the past, water source and underground water around will certainly polluting like this, the student is just taken exception to this from firm chemistry, their environmental consciousness is not sought fame and wealth naturally, for environmental protection is really fulfilled, need to solve above-mentioned customary practice.
Summary of the invention:
It is simple, convenient that the purpose of this utility model provides a kind of device, effectively controlled laboratory waste liquid and produced the laboratory liquid waste treating apparatus that pollutes.The purpose of this utility model realizes by following structure: the utility model is a kind of laboratory liquid waste treating apparatus, salkali waste fluid cylinder and spent acid fluid cylinder are fixed on both sides, iron stand top by iron clamp respectively, iron stand bottom iron clamp installs and fixes acid-base neutralisation and handles cylinder, the soft plastics conduit of waste lye cylinder bottom portion is connected to acid-base neutralisation and handles cylinder top, the soft plastics conduit of spent acid solution cylinder bottom portion is connected with grass tube, the grass tube the other end is positioned at acid-base neutralisation and handles the cylinder bottom, acid-base neutralisation is handled cylinder bottom portion and is had waste liquid output soft plastics conduit, flow velocity is installed on this soft plastics conduit is reconciled switch.The utility model is simple to operation; This device utilizes depleted disposable medical plastics point drop bottle, has embodied the utilization again of resource; Utilize the disposable plastic stilligout can regulate the amount and the speed of liquid waste disposal at any time; Student's manipulation waste liquid has in person strengthened environmental consciousness; Effectively controlled the pollution that laboratory waste liquid causes; The principle that disposes waste liquid is the acid-base neutralisation reaction of the important knowledge point of junior middle school chemistry, and the student is studied in order to practise, and can also experience the important of learning chemistry.Working method: the spent acid after will testing, salkali waste are poured spent acid cylinder, salkali waste cylinder respectively into, reconcile flow rate switch and all be in closing condition this moment, before disposing waste liquid, in the acid-alkali treatment device, add a little phenolphthalein test solution in advance, open salkali waste cylinder switch, salkali waste solution is injected treater, waste liquid takes on a red color, open spent acid cylinder switch again, because the spent acid pipe box in Glass tubing, can be gone into the stirring of spent acid limit by marginal not, is just become colorless by redness until solution, close spent acid cylinder switch immediately, will be processed into the discharging of neutral solution then.
Description of drawings:
Fig. 1 is the utility model structure diagram
Embodiment:
The utility model as shown in Figure 1 is a kind of laboratory liquid waste treating apparatus, salkali waste fluid cylinder 1 and spent acid fluid cylinder 2 are fixed on both sides, iron stand 8 top by iron clamp 7 respectively, the iron clamp 7 of iron stand 8 bottoms installs and fixes acid-base neutralisation and handles cylinder 3, the soft plastics conduit 5 that the waste lye cylinder bottom is 1 one is connected to acid-base neutralisation and handles cylinder 3 tops, the soft plastics conduit 5 of spent acid fluid cylinder 2 bottoms is connected with grass tube 6, grass tube 6 the other ends are positioned at acid-base neutralisation and handle cylinder 3 bottoms, acid-base neutralisation is handled cylinder 3 bottoms and is had waste liquid output soft plastics conduit 5, flow velocity is installed on this soft plastics conduit 5 is reconciled switch 4.Flow velocity all is installed on the soft plastics conduit 5 of the soft plastics conduit 5 of waste lye cylinder bottom portion 1, spent acid fluid cylinder 2 bottoms is reconciled switch 4.Can utilize depleted disposable medical plastics point drop bottle as cylinder body in the present embodiment, embody the utilization again of resource; Utilize the disposable plastic stilligout can regulate the amount and the speed of liquid waste disposal at any time.
