Description

Technical Field

[0001] The utility model belongs to the technical field of samplers, and more specifically relates to a closed sampler for sodium electrolyte. Background Art

[0002] In chemical production enterprises, electrolyte sampling is an important part of quality management. Testing the electrolyte can truly reflect the properties of the electrolyte. Usually, in the production process of electrolytes (such as lithium ion and sodium ion electrolytes), the purity, moisture and other indicators of each component are strictly controlled. Once the electrolyte comes into contact with air during sampling or air is mixed in during the sampling process, it will cause deviations in the test results, affecting the accuracy of the test results.

[0003] However, this product still has some problems. The existing electrolyte sampler is assembled from ordinary water pipe joints on the market, which makes assembly cumbersome. The existing electrolyte sampler has poor sealing performance. The electrolyte in the electrolyte sampler will react chemically with the air, causing corrosion and rust on the pipes, which has a certain impact on the electrolyte sampling and testing standards. At the same time, it shortens the service life of the electrolyte sampler and increases replacement costs. In addition, most sampling operations are performed by placing the sampling device in a plastic bag flushed with nitrogen and connecting it to the sampling port. This makes the sampling process complicated and inconvenient. Sampling and removal of waste liquid is a waste of resources, polluting the environment, time-consuming and labor-intensive, and cannot achieve real-time and effective analysis and detection of the electrolyte composition at each link in the electrolyte preparation process.

[0019] Specific embodiment 1: Please refer to Figure 1-4 A sealed sodium electrolyte sampler includes a sampler 1 having openings at both ends. The upper and lower ends of the sampler 1 are provided with an inlet quick connector 2, which is fixedly connected to the upper opening; the lower end opening is provided with an outlet quick connector 3, which is fixedly connected to the lower opening. A handle 11 is provided on the side outer wall of the sampler 1 and is fixedly connected to the side outer wall of the sampler 1.

[0020] A first sealing ring 21 is further provided in the port of the inlet quick connector 2 , and the first sealing ring 21 is embedded in the inner side of the port groove of the inlet quick connector 2 .

[0021] A second sealing ring 31 is further provided in the port of the outlet quick connector 3 , and the second sealing ring 31 is embedded in the inner side of the port groove of the outlet quick connector 3 .

[0022] The inlet quick connector 2 and the outlet quick connector 3 are both compatible with the female connector provided on the outside. When the female connector is inserted into the quick connector, the pipeline becomes a passage; when the female connector is removed, the pipeline in the quick connector is closed, so that the cavity of the sampler 1 is completely sealed.

[0023] The sampler 1 also has an opening at the side end away from the handle 11, at which a sampling pipe 4 is disposed, which is fixedly connected to the side opening. A third sealing ring 41 is also disposed within the outlet end of the sampling pipe 4, which is embedded within the port groove of the sampling pipe 4. A concave groove chamber is defined in the middle of the port of the sampling pipe 4, and a plurality of limiting grooves 42 are evenly distributed around the periphery of the port, extending through the outer edge of the upper end of the port.

[0024] The outer periphery of the port of the sampling tube 4 is covered with a clamping cap 5. The inner periphery of the clamping cap 5 is provided with a limit block 52 that matches the multiple limit grooves 42. The limit block 52 is fixedly connected to the inner wall of the clamping cap 5. A cavity is provided in the middle of the clamping cap 5 so that the outer edge of the port of the sampling tube 4 is completely embedded in the cavity of the clamping cap 5. A through hole 51 is provided in the middle of the upper end of the clamping cap 5. The diameter of the through hole 51 is 3-8 mm. The through hole 51 is used to sample the liquid in the cavity of the sampler 1 through the external sampling needle.

[0025] A rubber gasket 6 is also pressed against the groove chamber in the middle of the compression cap 5 and the sampling pipe 4 port. The rubber gasket 6 is placed between the compression cap 5 and the sampling pipe 4 port, and the rubber gasket 6 always abuts against the through hole 51 so that the sampling needle can perform sampling in a sealed manner.

[0026] Working principle:

[0027] To sample, this practical device first connects the inlet and outlet quick connectors to the outer female quick connector and fully replaces the gas with nitrogen. After replacement, the sampler is connected to the pipeline through the inlet and outlet quick connectors. The connection method is a metal hose with female connectors at both ends, which facilitates connection to the inlet and outlet quick connectors. After sampling, the female connector is removed, and the sampler cavity is completely sealed. At the same time, the outer sampling needle can pierce the rubber gasket to extract the liquid in the sampler cavity.
