Gas purification type reagent cabinet capable of adjusting air distribution by sensing

Abstract

The invention discloses a gas purification type reagent cabinet capable of adjusting air distribution by sensing, comprising a gas purification part and a reagent placing part, wherein the gas purification part comprises a negative pressure air fan, an air outlet arranged above the negative pressure air fan, and an air inlet arranged below the negative pressure air fan, the reagent placing part comprises a rear wall, a front door, and a plurality of reagent placing platforms located between the rear wall and the front door, the rear wall is provided with an air distribution channel, the reagent placing platforms divide the reagent placing part into a plurality of unit layers, each unit layer is provided with an air distribution opening communicated with the air distribution channel, an optoelectronic switch and a solenoid valve, each optoelectronic switch is arranged on the rear wall and is toward the front door, the solenoid valves are arranged at the air distribution opening, when one optoelectronic switch senses a reagent, the corresponding solenoid valve is controlled to be opened, and otherwise the corresponding solenoid valve is closed. By adopting the gas purification type reagent cabinet, the air distribution condition can be adjusted according to placing positions of drugs in the reagent cabinet.

Description

Technical field [0001] The invention relates to a clean air type reagent cabinet capable of sensing and adjusting air distribution, belonging to the technical field of manufacturing reagent cabinets commonly used in chemical laboratories. The reagent cabinet is mainly used for storing and storing chemicals containing volatile and harmful components. Background technique [0002] For reagents containing volatile and harmful components, such as volatile acidic or alkaline solutions, flammable or explosive low-boiling organic gases, formaldehyde and other volatile gases harmful to the human body, many of them usually need to be placed in a ventilation, ventilation Functional special reagent cabinet; the above reagent cabinet is usually connected with the ventilation system in the laboratory, through the ventilation system, the air polluted by the volatile and harmful components in the reagents in the reagent cabinet is sucked and discharged into the atmosphere for dilution to avoid h...

AI Technical Summary

Problems solved by technology

[0003] The clean air type reagent cabinet in the prior art is usually provided with the air extraction equipment on the upper part of the cabinet body, and the air extraction equipment is directly connected to the top of the reagent cabinet, so when the ventilation operation is performed, the ventilation intensity at the bottom of the reagent cabinet is relatively high. Weak, it is difficult to fully suck the volatile harmful components, and simply increasing the ventilation rate can avoid the occurrence of the above problems, but the energy consumption will increase accordingly, thus increasing the use cost of the clean air reagent cabinet; in addition, The air purification type medicine cabinet in the prior art cannot adjust the air distribution according to the position of the medicine in the medicine cabinet
