Embodiment 1

[0033] A liquid metal sampler, comprising an outer tube 1 and an inner tube 2 that are sheathed together, the outer tube 1 is sleeved outside the inner tube 2 and there is a gap between the inner tube 2 and the outer tube 1, and the bottom of the inner tube 2 is provided with The sealing head 5 is provided with a plurality of liquid inlet holes between the sealing head 5 and the outer tube 1 . When the liquid metal sampler of this embodiment takes a sample, the liquid metal enters the inside of the outer tube 1 from the liquid inlet hole. The top of the inner tube 2 is connected with a lifting rod 4, and the lifting rod 4 can drive the inner tube 2 to move up and down inside the outer tube 1. When the lifting rod 4 drives the inner tube 2 to move downward, the inner tube 2 can be in close contact with the sealing head. In addition, both the side wall of the outer tube 1 and the side wall of the inner tube 2 are provided with exhaust holes.

Embodiment 2

[0036] This embodiment 2 is further improved on the basis of embodiment 1. A liquid metal sampler, comprising an outer tube 1 and an inner tube 2 that are sheathed together, the outer tube 1 is sleeved outside the inner tube 2 and there is a gap between the inner tube 2 and the outer tube 1, and the bottom of the inner tube 2 is provided with The sealing head 5 is provided with a plurality of liquid inlet holes between the sealing head 5 and the outer tube 1 . When the liquid metal sampler of this embodiment takes a sample, the liquid metal enters the inside of the outer tube 1 from the liquid inlet hole. The top of the inner tube 2 is connected with a lifting rod 4, and the lifting rod 4 can drive the inner tube 2 to move up and down inside the outer tube 1. When the lifting rod 4 drives the inner tube 2 to move downward, the inner tube 2 can be in close contact with the sealing head. In addition, both the side wall of the outer tube 1 and the side wall of the inner tube 2 ...

Embodiment 3

[0038] Embodiment 3 is further improved on the basis of Embodiment 2. Such as figure 1The liquid metal sampler shown is composed of an outer tube 1, an inner tube 2, a gland 3, a lifting rod 4 and a sealing head 5. The upper end of the outer tube 1 is provided with an external thread and a vent hole, and the upper end of the inner tube 2 is provided with an internal Thread and vent hole, the vent hole at the upper end of the outer tube 1 and the vent hole at the upper end of the inner tube 2 are located at the same horizontal position, which is conducive to the exhaust of the sampler and avoids the existence of air holes in the sample. The vent hole can be a waist-shaped hole to vent A pin is inserted in the hole so that the inner tube can only move up and down but not rotate. Gland 3 is provided with internal threads, the center of the top has a hole, and the diameter of the aperture is larger than the outer diameter of the upper end of lifting rod 4, so that lifting rod 4 c...

Abstract

The invention discloses a liquid metal sampler which comprises an outer pipe, an inner pipe, a lifting rod, a concave gland and a sealing head. The outer pipe sleeves outside the inner pipe; vent holes are arranged in the side wall of the outer pipe and the side wall of the inner pipe; a gap is reserved between the inner pipe and the outer pipe; the concave gland is located at the upper end of theouter pipe, a through hole is formed in the center of the top of the gland, the lower end of the lifting rod penetrates through the through hole, the lower end of the lifting rod is connected with the upper portion of the inner pipe, the sealing head is arranged at the bottom of the outer pipe, and a plurality of liquid inlet holes are formed between the sealing head and the outer pipe. The innerpipe is driven by the lifting rod to move up and down in the outer pipe, and the inner pipe can make close contact with the sealing head when moving downwards. The liquid metal sampler solves the problem of interference of impurities on the free surface of the liquid metal on the sample, ensures the accuracy of the sampling process and has the characteristics of simple and convenient operation.

Description

technical field [0001] The invention relates to the field of liquid sampling, in particular to a liquid metal sampler and a liquid metal sampling method. Background technique [0002] In scientific research and actual production, in order to accurately grasp the composition of liquid metal and understand the physical properties of liquid metal, it is often necessary to extract samples from containers containing liquid metal for composition analysis. In order to obtain a representative liquid metal sample, it is necessary to avoid the influence of impurities on the free surface of the liquid metal on the sample during the sampling process. [0003] The patented technology of the currently disclosed liquid metal sampler such as the Chinese patent (authorization number: CN205317520U), the Chinese patent (authorization number: CN2168247Y) can not completely solve the problem of the interference of impurities on the metal free surface to the sample, and the Chinese patent (author...
