Detailed Description
Referring to fig. 1 to 4, the present invention provides a laboratory ventilation device for intelligent manufacturing, including a ventilation box 1, wherein:
a working cavity is formed in the air changing box 1, an air inlet and an air outlet which are communicated with the working cavity are formed in the air changing box 1, an air purifier 2 and a first fan 3 are installed in the working cavity, a temperature adjusting mechanism is installed in the air outlet, an outer through pipe 4 communicated with the working cavity is installed on the air changing box 1, and a one-way filtering mechanism is installed in the outer through pipe 4;
when ventilating the laboratory, by a fan 3 work and through air inlet with air suction air purifier 2 in the laboratory and carry out purification treatment, the air that will purify again emits into the laboratory in, simultaneously can be according to actual conditions through leading to the outer tube 4 with external air suction work intracavity, can be so that let in the laboratory with external air, external air is when leading to outer tube 4 entering laboratory in, can be by one-way filter mechanism make outdoor air can only get into in the experiment, it is outdoor to reduce indoor air flow, can reduce pollution, carry out filtration treatment to outdoor air by one-way filter mechanism simultaneously, ensure that clean and fresh air gets into in the laboratory.
In a specific embodiment, the one-way filtering mechanism comprises an active carbon block 5, and a plurality of flow channels 6 are arranged on the active carbon block 5 in a penetrating manner;
the principle of runner 6 is the same with the principle of tesla valve, when the air in the laboratory gets into runner 6 in activated carbon block 5, because the design of runner 6, can slow down gaseous flow velocity, can make simultaneously activated carbon block 5 to the better adsorption filtration processing of the gas in the laboratory, when external gas gets into activated carbon block 5, because the design of runner 6, can ensure the normal circulation of air, carry out adsorption filtration processing to the air by activated carbon block 5 simultaneously, only can play adsorption filtration and one-way circulation's effect through an activated carbon block 5, and is with low costs, moreover, the steam generator is simple in structure.
In the specific embodiment, the temperature adjusting mechanism comprises a refrigerator 7, a heater 8, a cold conducting pipe 9 and a heat conducting pipe 10; the refrigerator 7 and the heater 8 are both arranged in the air exchange box 1, the cold guide pipe 9 is arranged on the refrigerator 7, the cold guide pipe 9 extends into the working cavity, and the heat conduction pipe 10 is arranged on the heater 8 and extends into the working cavity;
according to the needs of people, the temperature of the refrigerator 7 or the heater 8 can be respectively transferred into the working cavity by the working of the refrigerator 7 and the heater 8 through the cold conducting pipe 9 and the heat conducting pipe 10 to carry out temperature adjustment treatment on the air, so that the purified air can be adjusted according to the actual needs of people, and the refrigerator 7 and the heater 8 are independently installed without mutual interference.
