Non-duct self-purification medicine storage cabinet

Abstract

The invention provides a non-duct self-purification medicine storage cabinet, which enables volatile gases in the storage cabinet to be filtered to reach the harmless standard and be discharged insidea laboratory, achieves a high purification efficiency, enables the harmful and toxic gases to be purified and discharged as soon as possible and achieves a high processing amount in a unit time. Thenon-duct self-purification medicine storage cabinet comprises at least one cabinet body module; each cabinet body module comprises a cabinet body and a filter unit; the side wall of the cabinet body is internally provided with a vertically-arranged air passage; the lower part of the inner side wall of the cabinet body is provided with inner air inlets; the top part of the side wall of the cabinetbody is provided with inner air outlets; the inner air outlets are communicated with the filter unit; the filter unit comprises a cover shell arranged at the upper end of the cabinet body; the cover shell is provided with a main filter core, a filter saturation sensor, a safety filter core and a fan from bottom to top; and the top part of the cover shell is provided with outer air outlets.

Description

technical field [0001] The invention relates to the technical field of chemical medicine storage cabinets, in particular to a ductless self-cleaning medicine storage cabinet. Background technique [0002] When storing drugs in various test units and laboratories, a large amount of acid, alkali and organic volatile and easily decomposed drugs will produce a large amount of toxic, harmful and corrosive gases, smoke, particles and other harmful substances, endangering the safety and health of experimental operators. Damage to experimental equipment and pollute the surrounding environment. Therefore, it is necessary to ensure that toxic and harmful substances are discharged or purified smoothly, so as to meet the safety standards stipulated by the state for the laboratory environment. [0003] The Chinese invention patent with the notification number CN203709591U discloses a self-cleaning medicine storage cabinet, which is equipped with a filter system on the top of the cabinet ...

[0002] When storing drugs in various test units and laboratories, a large amount of acid, alkali and organic volatile and easily decomposed drugs will produce a large amount of toxic, harmful and corrosive gases, smoke, particles and other harmful substances, endangering the safety and health of experimental operators. Damage the experimental equipment and pollute the surrounding environment. Therefore, it is necessary to ensure that the toxic and harmful substances are discharged or purified smoothly, so as to meet the safety standards stipulated by the state for the laboratory environment.

[0003] The Chinese invention patent with the notification number CN203709591U discloses a self-cleaning medicine storage cabinet, which is equipped with a filter system on the top of the cabinet device, by allowing indoor air to enter the cabinet from the lower part of the cabinet, forcing the polluted air in the cabinet to flow upward into the cabinet. The filter device is used to filter, meet the harmless standard and discharge it inside the laboratory and purify the indoor air at the same time. However, because the molecular weight of a large amount of toxic, harmful and corrosive gases is greater than that of air, once the leakage of toxic and harmful gases occurs in the medicine storage cabinet, under the force of gravity Under the action, toxic, harmful and corrosive gases will be deposited at the bottom of the medicine storage cabinet, and it is difficult for the indoor air to enter the cabinet from the lower part of the cabinet to quickly rise the toxic, harmful and corrosive gases accumulated at the bottom of the cabinet, resulting in low purification efficiency. There is no centralized guidance for toxic, harmful and corrosive gases. Toxic, harmful and corrosive gases are constantly mixed in the cabinet with the air entering the cabinet. It is always difficult to completely discharge, the purification efficiency is low, and the processing capacity per unit time is low.
