Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for chemical engineering. Background Art

[0002] In the process of chemical engineering experiments, it is often necessary to conduct chemical sampling of chemical reagents, solutions, etc., and extract samples from the whole for testing the whole. During the sampling process, the samples need to be absorbed, stored, and then tested and analyzed. The sampling device is an indispensable instrument in chemical engineering.

[0003] The existing liquid sampling device has many shortcomings during use. Since chemical liquids will be stratified, the chemical liquid components at different depths will be different. Therefore, it is necessary to sample chemical liquids at different depths. However, the existing sampling device often manually controls the depth of liquids at different depths, and the manual control of the depth is not stable, resulting in certain differences in the sampled liquids. To this end, we propose a sampling device for chemical engineering. Utility Model Content

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The utility model embodiment discloses a sampling device for chemical engineering.

[0022] The utility model provides Figure 1-2A sampling device for chemical engineering shown in the figure comprises a sampling bottle 1, a liquid outlet 2 is provided on the sampling bottle 1, a water pump 3 is installed on the top outer wall of the sampling bottle 1, the water outlet end of the water pump 3 is connected to the interior of the sampling bottle 1, a delivery pipe 4 is connected to the water inlet end of the water pump 3, and the other end of the delivery pipe 4 is connected to a sampling barrel 7, an external thread 8 is provided on the sampling barrel 7, and the sampling barrel 7 is threadedly connected to a floating plate 9 through the external thread 8. By adjusting the position of the floating plate 9 on the sampling barrel 7, the sampling depth of the sampling barrel 7 can be adjusted, so that chemical liquids of different depths can be sampled stably, avoiding the instability caused by human operation.

[0023] The utility model discloses a sampling device for chemical engineering. A sampling bottle 1 is provided with an observation slot 5. The observation slot 5 is inlaid with transparent glass. A liquid level gauge 6 is provided on the transparent glass, which is convenient for observing the sampling amount inside the sampling bottle 1, thereby facilitating the control of the sampling amount.

[0024] The utility model discloses a sampling device for chemical engineering. The sampling tube 7 is provided with a strip groove 10. The inner wall of the strip groove 10 is provided with a scale 11. The scale 11 can be provided to facilitate and accurately adjust the position of the floating plate 9, thereby improving the convenience of use.

[0025] The utility model discloses a sampling device for chemical engineering, wherein a sampling tube 7 is threadedly connected with a sleeve 12 through an external thread 8, a protective sleeve is nested on the sleeve 12, and the protective sleeve is a rubber sleeve. The sleeve 12 and the protective sleeve are provided to protect the bottle mouth of a chemical liquid storage bottle, thereby preventing the sampling tube 7 from colliding with the bottle mouth and causing damage to the bottle mouth.

[0026] The utility model provides a sampling device for chemical engineering, wherein both ends of the sampling tube 7 are provided with limit rings 13, and the limit rings 13 are provided to limit the moving positions of the floating plate 9 and the sleeve 12, thereby preventing them from being separated from the sampling tube 7 and affecting the convenience of use.

[0027] When in use, after placing the sampling tube 7 into the chemical liquid storage bottle, the water pump 3 is then started to transport the chemical liquid into the sampling bottle 1 for sampling. When it is necessary to sample liquids of different depths, the float plate 9 can be rotated. Since the float plate 9 is threadedly connected to the external thread 8, the float plate 9 can be rotated to move up and down. By observing the position of the float plate 9 on the scale 11, the sampling depth can be accurately understood. During sampling, the position of the sleeve 12 can also be adjusted so that it can be located at the bottle mouth of the chemical storage bottle. This can prevent the sampling tube 7 from colliding with the bottle mouth during the sampling process, causing damage to the bottle mouth.
