Example 1
As shown in fig. 1 to 4, embodiment 1 of the present invention provides an automated liquid workstation with a protection function, including a workstation main body 1, wherein a working chamber 2, a filtering chamber 6, a left air duct, a right air duct 5 and a lower air duct 4 are formed in the workstation main body 1; the filter bin 6 is positioned at the top of the workstation main body 1, an exhaust port 11 is arranged at the top of the filter bin 6, the working bin 2 is positioned below the filter bin 6, a window is formed in the front side of the working bin 2, the left air duct and the right air duct 5 are respectively positioned on the left side and the right side of the working bin 2, and the lower air duct 4 is positioned below the working bin 2; the two sides of the lower air duct 4 are respectively communicated with the left air duct and the right air duct 5, the tops of the lower air duct and the right air duct are communicated with the working bin 2, the tops of the left air duct and the right air duct 5 are communicated with the filter bin 6, and the filter bin 6 is communicated with the working bin 2.
The protection principle of the automatic liquid workstation with the protection function is as follows:
waste gas that forms in the working bin 2 enters into the side seal way to both sides through the lower wind channel 4 of bottom under the effect of updraft ventilator 7 in the filter bin 6 is crossed at the top, and the side wind channel of rethread both sides enters into in the filter bin 6 at top, filters partly discharge to external environment through the filter bin 6 at top again at last, and another part passes through the top of working bin 2 sinks to form the downdraft 9 in the working bin 2. The negative pressure formed by the working chamber 2 also has an airflow flowing into the front window, which is called as "inlet airflow" 10, so that the waste gas in the working chamber 2 can be effectively prevented from being directly discharged, and meanwhile, the sinking air 9 continuously blows through the working area of the safety cabinet to protect the test object in the cabinet from being polluted by external dust or bacteria.
A workbench 21 is arranged in the working bin 2, and a refrigeration position, a PCR amplification instrument, a gun head, a centrifugal tube storage position and a waste liquid station are arranged on the workbench 21. And the workbench 21 is also provided with a liquid preparation professional manipulator and an instrument transfer mechanical group which are respectively used for transferring liquid and transferring instruments in the experiment process. The number and the position of setting up of refrigeration position and centrifuging tube storage position can set for as required.
Filter and be equipped with filtration system and induced draft fan 7 in the storehouse 6, induced draft fan 7 be used for with waste gas in the working bin 2 is followed respectively left side wind channel and 5 suction in right side wind channel extremely filter storehouse 6, and pass through filtration system will waste gas is through partial discharge after filtering, and another part returns to working bin 2.
The filtering system comprises top filtering cotton and bottom filtering cotton, the top filtering cotton is arranged at the top of the filtering bin 6, the bottom filtering cotton is arranged at the bottom of the filtering bin 6, after waste gas is filtered, one part of waste gas is discharged from the bottom filtering cotton in a filtering mode, and the other part of waste gas is discharged from the top filtering cotton in a filtering mode.
The waste gas in the filtering bin 6 is filtered before being discharged, so that the waste gas can be effectively prevented from polluting the external environment. Meanwhile, the other part enters from the top of the working bin 2 and sinks to form a sinking air flow 9, the sinking air flow 9 can protect the working table 21 in the working bin 2, the contact between the air inflow 10 from the window and the test object is prevented, and the test object is prevented from being polluted by external dust or bacteria.
An air inlet grille is further formed on the front side of the working bin 2 and is located at the top or the bottom of the window. The negative pressure created in the working chamber 2 will also have an airflow inflow window, referred to as the "inlet airflow" 10. The 'inlet flow' 10 is used for preventing aerosol possibly generated during microbial operation from escaping from the front window, and unfiltered inlet flow 10 is sucked into the lower air duct by the air inlet grille before reaching a working area, so that a test article is prevented from being polluted by outside air. Meanwhile, the sunken airflow 9 continuously blows through the working area of the safety cabinet to protect the test articles in the cabinet from being polluted by external dust or bacteria.
An ultraviolet lamp 8 is also arranged in the working bin. Besides the air draft fan 7, the filter bin is provided with an ultraviolet lamp 8 which can further kill the pollutants in the air.
The outer cover of the PCR amplification instrument is provided with an anti-pollution shell, and the interior of the anti-pollution shell is communicated with the filter bin 6 through a pipeline. The PCR amplification instrument is used in amplifying specific DNA segment and this process may be performed in vitro without needing to rely on colibacillus, saccharomycete and other organisms. Because the PCR amplification instrument needs to be heated during operation, a large amount of amplification products can be released when the cover is opened, and serious pollution is generated in the whole machine working bin 2. Therefore, the anti-pollution shell is designed to cover the PCR amplification instrument, and in the moment of uncovering the PCR amplification instrument, the pollutants generated by the exhaust fan are exhausted through the exhaust pipe and discharged into the whole machine filtering system.
The anti-pollution shell is also provided with a heat dissipation device which can discharge heat generated by the PCR amplification instrument.
According to the automatic liquid workstation with the protection function, after waste gas formed in the working bin 2 enters the filtering bin 6 at the top, part of the waste gas is filtered by the filtering bin 6 at the top and then discharged to the external environment, and the other part of the waste gas sinks to the working bin 2 through the top of the working bin 2 to form the sinking air flow 9. The sinking air flow 9 continuously blows through the working area of the safety cabinet to protect the test articles in the cabinet from being polluted by external dust or bacteria.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
