DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 The utility model provides a technical solution: a mobile liquid sampler, including a sampling tank 1, a first liquid discharge valve 2, a vacuum tank 3, a second liquid discharge valve 4, a bracket 5, a liquid suction valve 6, a liquid suction tube 7, a first vacuum valve 8, a second vacuum valve 9, a vacuum gauge 10, a push-type vacuum pump 11, a lifting handle 12, a quick-release buckle 13, a protective cover 14, a movable plate 15, a movable rod 16 and a fixing bolt 17.

[0028] When using the mobile liquid sampler, Figure 1 As shown, first, the sampler is moved to the corresponding sampling location by holding the handle 12, which is convenient to carry and take. In addition, during the movement, the protective cover 14 is arranged on the outside of the sampling tank 1 and the vacuum tank 3, which can provide a good protection effect for the sampling tank 1 and the vacuum tank 3 to prevent damage caused by collision during the movement. When moving to the sampling point, combined with Figure 2 and Figure 4As shown, by rotating the fixing bolt 17, the fixing bolt 17 is respectively threadedly connected with the protective covers 14 on the left and right sides, the fixing bolt 17 loosens the limit between the protective covers 14 on the left and right sides, and then pulls the protective covers 14 to both sides, and the protective covers 14 drive the movable plate 15 and the bracket 5 to move, and at the same time, the movable rod 16 slides with the bottom of the bracket 5, thereby driving the protective cover 14 to extend and retract to both sides, and the protective cover 14 is moved away from the outside of the sampling tank 1 and the vacuum tank 3. At the same time, the protective cover 14 can stably support the sampler, thereby improving the stability of the sampler during use;

[0029] like Figure 3 As shown, before use, check and close all valves, open the first vacuum valve 8 between the sampling tank 1 and the vacuum tank 3, use a vacuum pump to connect the second vacuum valve 9 to simultaneously pump the vacuum tank 3 and the sampling tank 1 into a high vacuum, and the vacuum gauge 10 shows that the vacuum degree is greater than -0.008MPa. At this time, the vacuum can be turned off, and the sampler hand-held handle 12 can be removed and carried to any place by hand for sampling, and then the pipette 7 is extended into the container or the solvent of the tank truck for sampling, and the suction valve 6 is opened, and the liquid is sucked into the sampling tank 1. After the liquid is sucked to the specified liquid level, the suction valve 6 and the first vacuum valve 8 are closed, and the suction valve 6 on the upper part of the sampling tank 1 is opened, and the liquid is released from the bottom to In the sampling bottle, if a second sampling is required, first close the suction valve 6 and the first discharge valve 2, then extend the suction tube 7 into the sampling container, and then open the first vacuum valve 8 and the suction valve 6 connected in the middle to absorb the liquid solvent into the sampling tank 1 again, and release the sampled solvent again. During the sampling operation, the vacuum value can be observed at any time to replenish air in time. This solution utilizes two small vacuum tanks connected in series, namely the sampling tank 1 and the vacuum tank 3, to absorb the organic solvent into the sampling tank 1 once or multiple times through different operations, and discharge the liquid into the sample bottle for detection and analysis, and the upper end cover of the sampling tank 1 is connected with a quick-release buckle 13, which can be cleaned and disinfected after each sampling.

[0030] In addition, the sampling tank 1 is designed to be 0.5~2L to meet the sampling volume required for daily inspection, and the vacuum tank 3 is designed to be 2~8L larger, so that the purpose of multiple sampling can be achieved. In addition to being able to be connected to a vacuum pump to evacuate air, the vacuum tank 3 is also equipped with a push-type vacuum pump 11. The push-type vacuum pump 11 can also be manually pressed to achieve sufficient vacuum for sampling, making the entire vacuum suction and discharge operation very simple and convenient, effectively improving the efficiency of sampling. At the same time, the entire sampling process is accurate. When sucking materials, as long as the sampling tube is extended to the specified position, the liquid level sample at any position can be taken, and sampling can be performed on different parts.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
