Problems solved by technology

[0002] Fountain experiment is a demonstration experiment in middle school chemistry teaching. When talking about the properties of ammonia in the senior one chemistry textbook, a fountain experiment was arranged. Because the fountain experiment is very interesting and intuitive, it has surpassed the fountain experiment arranged in the textbook. The range has evolved into a series of fountain experiments. At present, although the existing fountain experimental devices have achieved basic operating performance, the overall structure is relatively simple, and it takes a lot of time to assemble and adjust before the experiment, which not only wastes a certain amount of time. At the same time, the experimental efficiency is reduced. At the same time, the traditional experiment needs to be carried out in two steps, which cannot achieve the integration of preparation and experiment, and reduces the practicability of the device. Therefore, it is necessary to improve the existing technology to solve the above problems.

Embodiment 1

[0025] see Figure 1-5 , an embodiment provided by the present invention: a device for ammonia fountain experiments, including a base 3 and a top plate 7, a detection chamber 11 is fixedly installed on the top of the top plate 7, and the detection chamber 11 and the top plate 7 are installed by screws Fixed, the front of the detection chamber 11 communicates with the third glass tube 22 through the first rubber hose 18, the bottom of the detection chamber 11 is fixedly equipped with the second glass conduit 13 corresponding to the second beaker 14, the top plate of the second glass conduit 13 7 is fixedly installed with the first glass conduit 12 corresponding to the third beaker 15, and the first glass conduit 12 communicates with the detection chamber 11 through the second rubber hose 26, and the inside of the detection chamber 11 is installed with a glass tube extending into the flask 10. The fourth glass conduit 25, and the fourth glass conduit 25 communicates with the sec...

Embodiment 2

[0028]This embodiment is further improved on the basis of Embodiment 1. A control switch 302 and a power jack 303 are fixedly installed on the front of the base 3 respectively. The control switch 302 is connected to the electric telescopic rod 6 and the heating plate 21 respectively The electrical connection is convenient for the control operation, and the power socket 303 is electrically connected with the battery 16 to charge the battery 16 .

[0029] Meanwhile, the bottom of the second glass conduit 13 is covered with a rubber sealing sleeve 1301 . In the embodiment, the rubber sealing sleeve 1301 can seal the second glass conduit 13 to ensure the sealing performance of the device inside the experiment, and the entry of outside air ensures the quality of the experiment.

Embodiment 3

[0031] This embodiment is further improved on the basis of Embodiment 2, and the inner wall of the heating cylinder 4 is fixedly installed with an asbestos layer 401 . In the embodiment, the asbestos layer 401 improves the heat insulation effect of the heating cylinder 4, avoids the situation that personnel's hands are burned during the experiment, and ensures the safety during the experiment.

[0032] The detection chamber 11 communicates with the second glass conduit 13 through a first connecting pipe 701 , and the second rubber hose 26 communicates with the first glass conduit 12 through a second connecting pipe 702 . In the embodiment, the first connecting pipe 701 and the second connecting pipe 702 play a good connecting role, which is convenient for the staff to disassemble and clean.

Abstract

The invention discloses a device for an ammonia gas fountain experiment and belongs to the field of chemical experiment devices. The device comprises a base and a top plate, a placement groove is formed inside the base, a storage battery is mounted in the placement groove in an embedded manner, the top plate is fixedly mounted at the top of the base through an electric extensible rod, a heating barrel is fixedly mounted at the top of the base on one side of the electric extensible rod, a heating plate is fixedly mounted at the bottom end inside the heating barrel through a resistance heating ring, a first beaker extending out of the heating barrel is placed on the heating plate, and a third glass tube which is through is fixedly mounted at the top of the first beaker through a sealing cover. By arranging the electric extensible rod, the device realizes electric operation, and working personnel can adjust operation height of the device according to actual conditions, so that conventional manual adjusting is avoided; by arranging the heating barrel, the device realizes performance of preparing ammonia gas through electric heating by the resistance heating ring, so that conventional fire heating is avoided, and the device is high in practicability and convenient for popularization and use.
