Description
Technical field
The present invention relates to a kind of microbe limit filter that microorganism is used that detects.
Background technology
A kind of Microbial Limit Filter Test Instrument that Chinese patent application ZL200720105905.0 relates to, its disclosed strainer is fixedly mounted on the casing of check meter, the interior system pipeline of bleed-off passage in the strainer and casing is communicated with, on system pipeline, be provided with the pressure-releasing electromagnetic valve that to eliminate negative pressure in the system pipeline, in the time of will taking off filtering cup after the filtration, to discharge the negative pressure in the bleed-off passage earlier, because pressure-releasing electromagnetic valve is located on the interior system pipeline of casing, and the system pipeline in the casing can not take out and sterilizes, during negative pressure in the magnetic valve bleed air operation discharges bleed-off passage, microorganism in the pipeline can cause microorganism detection inaccurate by the direct contaminated filter film of circulation of gas.
Summary of the invention
The objective of the invention is provides a kind of strainer for the deficiency that solves above-mentioned technology, can carry out the damp and hot bacterium that comes separately with inspection product contact part, and the microbe limit filter of microbial contamination can not take place because of the pipeline microbiological contamination when the release negative pressure.
In order to achieve the above object, a kind of microbe limit filter that the present invention is designed, it comprises filtering head, is provided with purging valve on filtering head, and the blow-out switch of purging valve is located at the side surface direction of filtering head, and the purging valve the other end communicates with bleed-off passage.Discharge negative pressure for convenience and take off filtering cup, outside filtering head, be provided with cup drawing device, be provided with between cup drawing device and the filtering head rotation up structure, the blow-out switch of purging valve by with the cup drawing device inwall touch from and folding.Take off the timely disinfecting action of filtering head for convenience, guarantee the aseptic of filtering head and bleed-off passage thereof, filtering head has bearing, be provided with card slot type between filtering head and the bearing and shirk locating structure, rest base is provided with the mouth of bleeding that communicates with bleed-off passage, carries out filter operation on the bleed line to make things convenient for filtering head to be connected with the microbial limit instrument by bearing or directly to be connected by bearing.Take off the filtering cup after the filtration for convenience, the up structure of the rotation between described cup drawing device and the filtering head is wherein to offer skewed slot on the side on the cylindrical surface between cup drawing device and the filtering head, and opposite side is established chase mortise at corresponding skewed slot place.Described chase mortise can be pin, screw, hoodle etc.Between the bottom of filtering head and bearing, be provided with the pilot hole pin, filtering head can be placed on the bearing by the position of determining.
The resulting a kind of microbe limit filter of the present invention, filtering head can conveniently take off from the bearing to be cleared up and sterilizes, avoided the microbial contamination of filtering head, when operation, after suction filtration is finished as long as the rotation cup drawing device; the cup drawing device inwall is pressed into the blow-out switch of purging valve, and purging valve just can be opened, and slowly eliminates the negative pressure in the system pipeline; make that to get film easier; not fragile, non-recoil gas is because venting port is in the side of filtering head; and be in the gnotobasis; and the bleed-off passage in the filtering head is a sterile channel, so can not produce microbial contamination because of pipeline gas recoil filtering membrane in the deflation course, not guarantee accuracy of experimental results.
In addition, at the rotation cup drawing device, the operator is as long as rotate cup drawing device gently, and cup drawing device will upwards move, and up to cup and strainer are thrown off fully, filtering cup can conveniently be taken off, and enters next step yeast culture analysis.
