Description
Technical field
The utility model belongs to the field of medical instrument technology, more particularly, to sample bottle filtration apparatus.
Background technology
With the occupational health detection development of analytical instrument sampling technique, many samples are both needed to using sample bottle to solid
Adsorption particle thing is desorbed, and draws stripping liquid, and stripping liquid and solid absorption during this sample bottle sample introduction with sample introduction end
Grain thing does not separate, so as to cause the offset of sample size desired value and actual value, makes the repeatability and accuracy of instrument analysis results
Reduce.
Solving the problems, such as this most viable and effective manner is taken the stripping liquid of sample bottle and solid absorption particulate matter point
From measure, allow sample introduction end to avoid contact with solid absorption particulate matter.But existing market there is no can be effectively separated desorption
The device of liquid and solid absorption particulate matter.
The content of the invention
For the technical problem situation mentioned in background technology, the technical solution of the utility model can incite somebody to action in sample bottle
Stripping liquid and solid absorption particulate separation, avoid sample introduction end in contact solid absorption particulate matter, so as to ensure sample size desired value
With actual value without offset, ensure the repeatability and accuracy of instrument analysis results.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
Sample bottle filtration apparatus, the filtration apparatus are located in sample bottle, and the sample bottle includes bottle and valve protection cap, the bottle
Body top is equipped with valve protection cap fixed part, and the valve protection cap is fixedly connected with the valve protection cap fixed part, the filtration apparatus include filter screen,
O-ring and spring, the spring bottom end are fixedly connected with the bottle inner bottom surface, and the filter screen top is tubular structure, under
Portion is inverted conical structure, which is located in the spring, and the O-ring is fixedly arranged on outside the filter screen top
Enclose, which forms circumferential sealing to the gap between the valve protection cap fixed part and the filter screen.
Further, the valve protection cap fixed part periphery is equipped with external screw thread, and internal thread, the valve protection cap screw thread are equipped with the valve protection cap
It is connected on the valve protection cap fixed part.
Further, the peripheral gap length between the valve protection cap fixed part inner wall of the filter screen is valve protection cap fixed part internal diameter
1/5.
Further, when the valve protection cap is being in tight condition on the valve protection cap fixed part, the filter screen lower part is fallen
Conical structure extrudes the spring, is abutted at the top of the filter screen with the valve protection cap inner top surface.
Further, the circular cone drift angle of the rounding wimble structure is 60 °.
The utility model has the advantages and positive effects of：By simple and effective way, solves occupational health inspection
The problem of sample introduction end sample size repeatability and accuracy reduce in work is surveyed, after the filtration apparatus, sample introduction end enters filtering
Stripping liquid is drawn in device, solid absorption particulate matter will not be contacted again；The filtration apparatus can be used for inorganic and organic solution at the same time,
It is and reusable after cleaning；The filtration apparatus includes and seals, fix, highly adjust, buffer and place restrictions on annex etc., can ensure
The compatibility and processing safety of sample bottle.
