Embodiment Construction

[0018] An example of a sampler is Figure 1~2 Shown: including a sampling cylinder, the sampling cylinder includes a cylinder body 6 whose axis extends along the left and right directions, the two ends of the cylinder body are respectively provided with a left end cover and a right end cover, and the cylinder body is guided and slidably slidably equipped with a left piston 5 and a right piston. 4. A sample transfer space 2 is formed between the left and right pistons, and a piston connecting rod 3 is arranged between the left and right pistons. The piston connecting rod can ensure the synchronous movement of the left and right pistons. The sampling cylinder also includes driving the left and right pistons. A piston driving mechanism in which the piston reciprocates left and right in the cylinder. The piston driving mechanism includes a transmission rod 7 whose axis extends in the left and right directions. The left end of the transmission rod is screwed on the left end cover. T...

Abstract

The invention relates to a sampler and a sampling tube thereof. The sampling tube comprises a cylinder with axis extending along a left and right direction; a left piston and right piston are assembled in the cylinder along an axial direction in a sealing and sliding manner; a sample material transfer space is formed between the left piston and the right piston; the sampling tube also includes a piston driving mechanism for driving the pistons to carry out left and right reciprocating movement in the cylinder; a sample inlet and a sample outlet at intervals are axially arranged on the cylinder; and during the left and right reciprocating movement, the pistons have a first working position, which seals the sample outlet and communicates the sample material transfer space with the sample inlet, and a second working position, which seals the sample inlet and communicates the sample material transfer space with the sample outlet. The invention solves the problem that the sample material is easily affected by the extraneous environment during sampling.

Description

technical field [0001] The present invention relates to a sampler and its sampling cylinder. Background technique [0002] At present, when sampling some unstable chemicals that are easily decomposed by water or air (such as lithium hexafluorophosphate), it is necessary to place the sampling bottle in an inert gas atmosphere and take samples from the production line pipelines, packaging barrels and other sample storage devices. Lithium hexafluorophosphate has poor stability, is easily decomposed in contact with water, and has extremely low impurity content requirements. When sampling with the current sampling bottle, when the sampling bottle is opened or closed, it is easily affected by the external environment, which directly leads to changes in the sample, thereby analyzing the results. If there is a deviation, the actual product weight cannot be intuitively reflected, which is not conducive to the central control adjustment of production. In addition, the sampling volume...
