Abstract
The utility model relates to a demonstiator for carbon oxide reducing metal oxidate used for chemical teaching, comprising straight tubes and bent tubes which are connected into the integration, wherein, the lower ends of the bent tubes are hermetically inserted into a container; the walls of upper sides of the container are provided with a tip mouth tube with upswept tip mouths, which is communicated with the container; the part of the straight tube which is positioned on the upper part of the tip mouth can be filled with metal oxide; the container is filled with lime water and communicated with carbon monoxide through the straight tube; the carbon monoxide which is positioned on the tip position of the tip mouth tube is ignited to heat the metal oxide, and the reduction process can be clearly observed. The utility model has the advantages of no use of alcohol burners, simple operation, time saving, gas saving, and reagent saving. The carbon monoxide which is directly generated from the utility model can be used for heating, and the utility model is propitious to environmental protection.
Description
The utility model relates to a kind of chemical teaching aid, particularly a kind of carbon monoxide reducing metal oxide demonstrator.
The teaching aid that is used at present demonstrating the carbon monoxide reducing metal oxide in the high school chemistry teaching be by the straight tube of some splits, 90 ° bend pipe, combine with the container and the spirit lamp of airtight soft bottle stopper, as China's existing junior middle school " chemistry " teach the 99th page of book (complete) disclose so a kind of teaching aid, its shortcoming is (1) operation inconvenience and time-consuming; (2) need the special spirit lamp that heats usefulness of configuration; (3) there is carbon monoxide waste gas to emerge and fails to utilize it, not only take gas but also do not have the environmental protection of being suitable for; (4) used metal oxide reagent is many, and waste is big, the testing expenses height.
The purpose of this utility model be to provide a kind of easy and simple to handle, save time, economize gas, economize reagent, do not need spirit lamp, and can make full use of the carbon monoxide of emerging and reduce its a kind of novel carbon monoxide reducing metal oxide demonstrator to greatest extent the indoor environment influence.
The technical solution of the utility model is such:
A kind of carbon monoxide reducing metal oxide demonstrator, comprise a horizontal straight tube that fuses and reclinate elbow, the container that has airtight stopper is characterized in that the lower end of described elbow is plugged in the described container by the hole in the middle of the described stopper, and can rotate within it; On the upper side wall of container, be provided with the sharp nozzle tube that Yi Jianzui upwarps, rotary container, sharp mouth can near or away from the lower wall of straight tube.
Owing to adopted such scheme, the utility model is than existing demonstrator of the same race, the one, operate more convenient, save time, economize gas, province's reagent; Two can save spirit lamp, and three can make full use of harmful carbon monoxide waste gas, help environmental friendly indoor.
Be further described below in conjunction with accompanying drawing 1 and embodiment.
Fig. 1 is a structural representation of the present utility model.
Carbon monoxide reducing metal oxide demonstrator shown in Fig. 1 comprises a horizontal straight tube 1, and itself and a right angle elbow 2 join together; The middle part of straight tube 1 is a cavity 5 thicker than straight tube 1 remainder.The lower end of elbow 2 can relatively rotate straight tube 1 and container 4 by set airtight being plugged in the described container 4 in hole in the middle of the rubbery stopper 3; Be provided with one by one end and communicate with container on the upper side wall of container 4, the other end is the sharp nozzle tube 6 of the sharp mouth 61 that is upturned, and sharp mouth 61 is lower than straight tube 1, and it can be pressed close to or away from cavity 5 with the rotation of container 4.
Using method of the present utility model is such:
1. at first, the utility model is clipped on the iron stand, in container 4, adds a spot of lime water.
2. in the spherical cavity 5 of straight tube 1, add a spot of cupric oxide (or other metal oxide).
3. with sharp mouth 61 aligned with cavities 5 and the jam-pack stoppers 3 of gas outlet 6.
4. straight tube 1 is connected carbon monoxide gas bomb source of the gas, the air of ventilating to container is discharged fully.
5. light carbon monoxide (before lighting bottle in gas must test pure) at sharp mouth 61 places of sharp nozzle tube 6, about 10-30 is after second, the cupric oxide of black just is reduced into red copper, it is muddy that lime water becomes, reduction process is fairly obvious, simple to operate, save time, economize gas, economize reagent, do not have carbon monoxide to overflow yet.
Claims (2)
1. carbon monoxide reducing metal oxide demonstrator, comprise a horizontal straight tube that fuses (1) and reclinate elbow (2), the container (4) that has airtight stopper (3), the lower end that it is characterized in that described elbow (2) is plugged in the described container (4) by the hole in the middle of the described stopper (3), and can rotate within it; On the upper side wall of container (4), be provided with the sharp nozzle tube (6) that Yi Jianzui (61) upwarps, rotary container (4), sharp mouth (61) can near or away from the lower wall of straight tube (1).
2. according to claim 1 or 2 described demonstrators, it is characterized in that the part on the described sharp mouth of being positioned at of described straight tube (1) (61) is a cavity thick than other parts (5).
