Efficient smoke discharge device of laboratory small smelting furnace

Abstract

The invention discloses a high-efficiency smoke exhaust device for a laboratory small smelting furnace. At present, laboratory small-scale melting furnaces are used in laboratories, and the waste gas and harmful substances after melting are all in the laboratory, which are not easy to be discharged, and have adverse effects on human body and experimental equipment. The device includes: a box body, a centrifugal exhaust fan switch, a shroud, a smoke exhaust pipe, and a centrifugal exhaust fan; the centrifugal exhaust fan switch is installed inside the box body, and the box body is composed of three surfaces, For a smelting furnace, the deflector is connected to the casing and installed above the casing, the lower end of the exhaust pipe is connected to the upper end of the deflector, the centrifugal fan is installed on the upper end of the exhaust pipe, and is connected to the upper end of the exhaust pipe. The upper port of the smoke pipe is flush. The invention makes full use of the negative pressure generated by the height difference of the centrifugal exhaust fan and the smoke exhaust pipe, can efficiently discharge the waste gas and smoke generated by the small smelting furnace during the metal smelting process, reduces energy consumption, and improves work efficiency.

Description

technical field [0001] The invention belongs to the technical field of smelting equipment, and in particular relates to a high-efficiency smoke exhaust device for a laboratory small smelting furnace. Background technique [0002] In the process of metal smelting in the laboratory, a lot of waste gas and smoke will inevitably be produced in the laboratory, such as chlorine, carbon dioxide, sulfur dioxide and other gases. These gases stay in the laboratory for a long time, which will not only endanger human health, but also damage to experimental equipment. Judging from the current situation, most of the metal smelting in the laboratory uses exhaust fans, exhaust fans and other equipment to extract exhaust gas and smoke. These equipment are not only inefficient but also not clean, which not only affects the progress of the experiment, but also seriously affects the experiment. The health of personnel is not conducive to the development of scientific research. Contents of th...
