Energy-saving and environment-friendly laboratory fume hood

Abstract

The invention discloses an energy-saving and environment-friendly laboratory fume hood. A main body comprises a lower fume hood body provided with fume hood doors, and an open upper fume hood body which is mounted on the lower fume hood body and composed of a back board, side boards and a top board. A telescopic door board is mounted in an opening of the upper fume hood body. Lifting devices are mounted at the two ends of the telescopic door board. An air exhaust channel is mounted in the top of the upper fume hood body. An oblique guide plate is mounted under the air exhaust channel. The lifting devices comprise a pair of chains. Clamping rails are arranged at the two ends of the telescopic door board. Sliding grooves are mounted in the inner walls of the side boards. The front ends of the chains are mounted at the top of the telescopic door board and bypass the top board to extend to the rear side of the back board. Chain wheels are mounted on the top board, and the chains are wound around the chain wheels. A counter weight is fixed to the tail ends of the chains. A vertical guide plate perpendicular to the back board is mounted at the front end of the back board. The top of the vertical guide plate is connected to the oblique guide plate. An air dust is arranged between the vertical guide plate and the back board. A filter device is mounted between the bottom of the vertical guide plate and the back board.

Description

technical field [0001] The invention relates to the field of experimental fume hood manufacturing, in particular to an energy-saving and environment-friendly laboratory fume hood. Background technique [0002] Experimental fume hoods are widely used in a series of research places such as hospitals, schools, and various research institutes, including various laboratory countertops, laboratory instrumentation, ventilation system air supply and cleaning systems, etc., but the current laboratory use Most of them are laboratory benches, fume hoods and a series of equipment. In the laboratory, due to the use of various chemical substances, the air pollution in the laboratory is often caused. Some substances not only smell bad, but also harmful to health. The fume hood is an experimental An integral part of indoor ventilation design. In order to prevent laboratory workers from inhaling or ingesting some toxic, pathogenic or unknown toxic chemicals and organisms, the laboratory sho...

Problems solved by technology

[0004] However, at present, the structural planning levels of fume hoods are endless, so the actual use effects of fume hoods are also different. There is no design of fume hoods that can guarantee its beauty, energy saving, environmental protection, convenient operation, It is easy to overhaul and has a good ventilation effect, so it is urgent to design a fume hood with the above advantages in the current field.
