Description

Technical Field

[0001] The utility model relates to the field of sampling devices for chemical process detection, and more specifically, to a sampling device for chemical process detection. Background Art

[0002] Chemical industry has a very close relationship with human beings. In modern life, chemical products are indispensable almost anytime and anywhere. Material life such as clothing, food, housing, transportation, as well as spiritual life such as culture, art, and entertainment all need chemical products to serve them. The demand for chemical industry increases year by year, and the demand for chemical tools and equipment also increases accordingly. Take the liquid chemical sampler as an example, which is mainly used for sampling liquid chemical material testing;

[0003] The traditional liquid chemical sampler is not convenient for users to operate when in use, and is also complicated to install, which makes the user spend a long time using the device and is not convenient to install. The existing portable liquid chemical sampler cannot guarantee the safety of the staff when performing liquid chemical sampling work, which may cause injuries to the staff;

[0004] Among the existing samplers, CN211954797U discloses a portable liquid chemical sampler, including a device body, a rotating bar, a sample collection tank and a conveying tube. The bottom of the device body is fixedly connected with a rotating bar, the bottom of the rotating bar is fixedly connected with a conveying tube, one side of the conveying tube is fixedly connected with a sample collection tank, one side of the top of the sample collection tank is fixedly connected with a fixed block, the other side of the fixed block is internally fixedly connected with a heat insulating material, the top of the fixed block is fixedly connected with a connecting bar, the other side of the connecting bar is internally fixedly connected with a sealing material, a fixed block is provided on one side of the heat insulating material, a connecting bar is provided on one side of the fixed block, and a sealing material is provided on the other side of the top of the connecting bar. When the staff performs liquid chemical sampling work, the heat insulating material is used to prevent the sample temperature from being too high to cause scalding to the staff, and the sealing material is connected to the connecting bar so that the sealing cover can be quickly covered, thereby improving the convenience of the device;

[0005] In the above-mentioned invention, heat-insulating materials are used to protect the staff, and high-temperature chemical reagents are generally not taken out during sampling. In addition, the structure of the above-mentioned patent is complex and the operation is simple. When sampling, the hand still needs to grasp the device body, which makes the sampling operation inconvenient. When sampling from the tank body, it is necessary to insert and suck out from the tank mouth. The height of the tank body is different during sampling, which makes it inconvenient to flexibly adjust the sampling method. Utility Model Content
