Problems solved by technology

This kind of sampler mainly has the following deficiencies: 1. The sampler can only perform sampling at one depth usually, and cannot sample and analyze samples at different depths. It is also extremely inconvenient when sampling corrosive liquids; When sampling the samples, multiple containers can only be used to sample separately, which takes up a lot of space and is extremely inconvenient to operate; 3. When performing experiments on samples of different time periods, it is easy to misuse and cause the experiment to fail

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-3 Shown, a kind of time-delay sample dividing liquid sampler of the present invention comprises rotating chassis 1, test tube clamping groove 2, test tube 3, sample storage tube 4, columnar switch 6 and PLC controller 15, several test tube clamping grooves 2 ( The present embodiment adopts 6 test tube slots) to be evenly distributed on the rotating chassis 1 along the circumferential direction, as figure 2 As shown, a test tube 3 is arranged in each test tube slot 2, and several sample depositors 4 are uniformly arranged in the test tube 3 along the length direction (4 sample depositors are adopted in the figure). A sampling port 5 corresponding to the sample storage device 4 is provided; a columnar switch 6 is provided on the outside of the test tube slot 2, and the columnar switch 6 covers all the test tube slots 2 therein. Th...

Abstract

The invention relates to an experimental sampling device, and in particular relates to a time delay sampling liquid sampler and a sampling method thereof. The liquid sampler includes test tubes, a rotary chassis, a PLC controller, test tube clamping grooves and column switches, the plurality of test tube clamping grooves are uniformly arranged on the upper end surface of the rotary chassis along the circumferential direction, one test tube is arranged in each test tube clamping groove, the column switches are arranged at the outer side of the test tube clamping grooves, the column switches are provided with switch ports, the PLC controls rotation of the rotary chassis to further drive the tubes in the test tube clamping grooves to rotate, so that the switch ports and test tube sampling ports can be in coincidence at different positions, and the purpose of time delay sampling can be achieved; through uniform arrangement of a plurality of sample storage devices in each test tube along the length direction, and when the switch ports and the test tube sampling ports are in coincidence, samples in different depths flow into the sample storing devices at different heights to realize sampling of the samples in different depths.

Description

technical field [0001] The invention relates to an experimental sampling device, in particular to a time-delayed sample dividing liquid sampler and a sampling method. Background technique [0002] In the laboratory, the sampler is a commonly used experimental instrument. The traditional liquid sampler uses an open container to directly sample from the sample pool, and then draws the sample from the sampler with a straw for experimentation. This kind of sampler mainly has the following deficiencies: 1. The sampler can only perform sampling at one depth usually, and cannot sample and analyze samples at different depths. It is also extremely inconvenient when sampling corrosive liquids; When sampling the samples, only multiple containers can be used to sample separately, which takes up a lot of space and is extremely inconvenient to operate; 3. When performing experiments on samples of different time periods, it is easy to misuse and cause the experiment to fail. Contents of...
