Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.
Example 1
The sampling device of the buried tank that this embodiment provided, concrete technical scheme is as follows:
bury sampling device of ground jar is equipped with the sample bottle 1 of drain hole 11 including the bottom, and sample bottle 1 communicates through sampling tube 2 and the sample connection of burying ground jar, and the sample in the sample bottle 1 can be through the drain hole 11 ejection of compact of bottom, need not rotatory uncapping again. The top of the sampling bottle 1 is communicated with a rubber ball 4 through a negative pressure pipe 3, the rubber ball 4 is extruded, and air in the sampling bottle 1 is removed to enable the sampling bottle to be in a negative pressure state, so that a sample can be taken out from a sampling port of a buried tank. The negative pressure pipe 3 communicates with a filter member 5, and the filter member 5 is configured to absorb moisture and filter dust from air introduced into the sampling bottle 1. The filtering piece 5 absorbs moisture of air and filters dust, so that moisture and metal ions substituted by dust are prevented from entering the sampling bottle 1.
In this embodiment, the sampling bottle 1 is transparent and has a scale. Thus, the sample amount in the sampling bottle 1 can be monitored conveniently in real time. When the sampling bottle is transparent glass bottle material, in order to prevent the glass bottle breakage, add the protection steel bushing outside, strengthen its practicality.
In this embodiment, the discharge port 11 is provided with a discharge valve 12. The discharge valve 12 is used to control the opening and closing of the discharge port 11.
In this embodiment the sampling tube 2 is provided with a sampling valve 21 and communicates with the sampling port of the buried tank through a hose 22. Sampling valve 21 can be used for carrying out the separation with the thief hatch of burying the ground jar and sampling bottle 1, the opening and close of management and control sample. The flexibility of the connection can be increased by the provision of the hose 22 when the sampling bottle 1 is shaken for cleaning.
In this embodiment, two first check valves 41 are provided at both ends of the rubber ball 4. The first check valve 41 is used to prevent the material in the sampling bottle 1 from flowing back to the rubber ball 4, which causes contamination of the sample.
In this embodiment, the filter member 5 is provided with a second check valve 51 at an end thereof adjacent to the sampling flask 1, and a vent valve 52 at an end thereof remote from the sampling flask 1. The second check valve 51 is used to prevent the material in the sampling bottle 1 from flowing back to the filter 5, which causes contamination of the sample. The vent valve 52 is used to regulate whether air is allowed to pass through the filter 5 into the sampling bottle 1.
In the present embodiment, the color-changing silica gel 53 is contained in the filter member 5. The allochroic silica gel 53 can absorb moisture and change color, thereby being convenient for visually monitoring the moisture absorbed by the allochroic silica gel.
In summary, the sampling device of the ground-burying tank provided by the embodiment has the following general implementation modes:
the hose that sampling valve 21 links to each other is connected through the cutting ferrule with the sample connection of burying ground jar, opens the feed valve when beginning the sample, closes blow-off valve 52 and baiting valve 12, through extrusion rubber ball 4, makes sampling bottle 1 form the negative pressure, will bury the material extraction of ground jar and come. And observing whether the sampling volume meets the requirement or not through the scale of the sampling bottle 1. When the sample volume is reached, the feed valve is closed, and the vent valve 52 and the discharge valve 12 are opened in sequence to place the sample into a pre-dried sample bottle. The air at this moment is dried by the filtering piece 5 containing the allochroic silica gel 53 and enters the glass sampling bottle 1, and the moisture content in the sample is not greatly influenced. In the sampling process of the original equipment, the actual moisture of the product is 150ppm, but in the sampling process, due to the influence of the environmental humidity, the final detected moisture is 250 ppm. After the sampling device of the buried tank provided by the embodiment is used, the product moisture is detected to be 160-170 ppm. The influence of the ambient humidity is greatly reduced.
The above description is only for the purpose of illustrating preferred embodiments of the present invention and is not to be construed as limiting the utility model, and the present invention is not limited to the above examples, and those skilled in the art should also be able to make various changes, modifications, additions or substitutions within the spirit and scope of the present invention.
