The purpose of such description is to clearly express the technical solution, and it should not be understood as an improper limitation on the technical solution of this application.

[0038] The utility model aims to solve the technical problem of low efficiency of obtaining samples by filtration in the prior art. Figure 1-3 As shown, the present technical solution still adopts the commonly used suction filtration pump 1 in the laboratory, which has a suction filtration inlet pipe 2 and a suction filtration outlet pipe 3. In order to achieve rapid acquisition of samples, the present technical solution is improved in two aspects, the first of which is to increase the flux and improve the efficiency, specifically:

[0039] An oil filter main pipe 10 is provided, and the oil filter main pipe 10 can be supported on a horizontal plane to keep the oil filter main pipe 10 itself arranged horizontally;

[0040] A plurality of filtered oil receiving container assemblies 20 are respectively connected to the filtered oil main pipe 10, so that the plurality of filtered oil receiving container assemblies 20 are connected in parallel; thus, a plurality of groups of samples can be obtained after the filtration pump 1 is started at the same time;

[0041] Each container assembly 20 includes a receiving bottle 21 and a bottle opener 22;

[0042] The receiving bottle 21 is used to receive the filtered oil, i.e., the sample, delivered by the filtration pump;

[0044] The sample is filtered into a receiving bottle 21 and maintained in communication with the atmosphere through an open bottle device 22 to stabilize the sample liquid phase.

[0045] Therefore, the technical solution has the advantages of quick assembly, large filtration volume, fast sample acquisition, and the ability to obtain multiple samples at the same time to improve work efficiency; it can also be switched through the cut-off valve 13 for single or selective use.

[0046] In a specific embodiment, see Figure 1 , 2 As shown, one end of the oil filter main pipe 10 is closed, and the other end has an interface 11 , and the interface 11 is connected to the suction filtration outlet pipe 3 .

[0052] The test bottle clamp 31 here adopts the flask test bottle clamp commonly used in the prior art. Its main function is to clamp the bottle mouths of two flasks together to form a temporary connection. The main purpose here is to connect the open bottle body 220 and the access component 30 to balance the filtration and obtain the volatile gas phase in the sample.

[0053] In a specific embodiment, see Figure 1As shown, the lower end of the access component 30 forms a cover body 310, and the cover body 310 can cover the connection port 210 of the receiving bottle 21; the inside of the cover body 310 forms a platform 311, and an introduction space 230 is formed between the connection port 210 and the cover body 310;
