Abstract
A kind of chemical laboratory exhaust apparatus, the fixing exhaust fan at casing middle part, the casing rear sidewall has groove, be inserted with gas-particulate filter in this groove, the top of respective grooves is opening, and gas-particulate filter inserts the groove from top opening, gas-particulate filter is the sandwich that latticed body constitutes, inner lining stone cotton, the chemicals sorbing material of filling can be changed according to the gas that experiment produces, but on the anterior air outlet of casing the unidirectional folding dust excluding plate of venetian blind type is housed.This device has the tail gas of absorption and dustproof effect, poisonous, the pernicious gas sucking-off of chemical laboratory can be arranged to atmosphere after also filtering again, can keep breadboard air quality, pollutant atmosphere not again, can also prevent to bring in the outside air inlet chamber contamination by dust laboratory apparatus, guarantee the accuracy of experiment and help the maintenance of laboratory apparatus.
Description
Technical field:
The utility model relates to the chemical laboratory exhaust apparatus, is used for poisonous, the pernicious gas that carry out the generation of chemical experiment process are discharged from the laboratory.
Background technology:
The exhaust apparatus of chemical laboratory is very simple at present, just in the air exhaust passage of wall, exhaust fan has been installed, though can play the effect of air draft, but have certain defective: at first indoor-outdoor air communicates, outside air is directly in the inlet chamber, unavoidably bring many dusts into when running into the big weather of travel fatigue, polluted laboratory apparatus, article, poisonous, the harmful gas when next is tested can be discharged to produce in the atmosphere and pollute.
Summary of the invention:
The purpose of this utility model provides a kind of chemical laboratory exhaust apparatus, and poisonous, the pernicious gas that the chemical experiment process can be produced also filter from the laboratory sucking-off, can also prevent to bring the contamination by dust laboratory apparatus in the direct inlet chamber of outside air.
The purpose of this utility model realizes as follows: this device relates to the exhaust fan that is fixed on the casing, on the air inlet of casing rear portion gas-particulate filter is housed.
On the anterior air outlet of casing, but the unidirectional folding dust excluding plate of venetian blind type is housed, when outside air draft, can blows open by wind-force, close during other state and.
Gas-particulate filter is the sandwich that latticed body constitutes, the inner chemicals sorbing material of filling, and sorbing material is selected different materials according to different chemicals laboratories.
The casing rear sidewall has groove, and the top of respective grooves is opening, and gas-particulate filter is inserted in from above in the groove, and back for convenience detach is cleaned or changed.
This chemical laboratory exhaust apparatus has the tail gas of absorption and dustproof effect, poisonous, the pernicious gas sucking-off of chemical laboratory can be arranged to atmosphere after also filtering again, can keep breadboard air quality, pollutant atmosphere not again, can also prevent to bring in the outside air inlet chamber contamination by dust laboratory apparatus, guarantee the accuracy of experiment and help the laboratory apparatus maintenance.
Description of drawings:
Accompanying drawing is the structural representation of the utility model chemical laboratory exhaust apparatus.
The specific embodiment:
With reference to accompanying drawing, the fixing exhaust fan 4 at casing 3 middle parts, casing 3 rear sidewall have groove 2, are inserted with gas-particulate filter 1 in this groove 2, and the top of respective grooves 2 is opening, makes things convenient for gas-particulate filter 1 to insert groove 2, changes when absorbing medicine and extracts out from the upper end.Gas-particulate filter 1 is the sandwich that latticed body constitutes, lid is arranged above, inner lining stone cotton, the chemicals sorbing material of filling can be changed according to the gas that experiment produces, but the unidirectional folding dust excluding plate 6 of venetian blind type is housed on casing 3 anterior air outlets, porose on the sidewall of casing front portion 5, with screw dust excluding plate 6 is installed by the hole, dust excluding plate 6 can be swung, dust excluding plate 6 arranged verticals intercept circulation of air at ordinary times, in order to prevent that dust excluding plate 6 from inwardly rotating, the width of casing front portion 5 increases slightly, when dust excluding plate 6 is desired inwardly swing, its dual-side leans against on the box bilateral wall limited, when exhaust fan 4 work, dust excluding plate 6 is outwards swing under the effect of air-flow, and air can be discharged in the atmosphere.
