In this way, the sample liquid in the industrial pipeline can be injected into the collection bottle. As Figure 2 shown, the liquid supply pipeline 2, the first selection valve 6 and the second selection valve 35 are fixedly arranged on the vertical plate 4.
[0037] The lifting drive can drive the needle holder 31 and the movable frame 32 to approach or move away from each other to complete the liquid separation operation. In this embodiment, the lifting drive includes a stepping motor, a transmission mechanism and a lifting platform. The stepping motor is fixedly arranged on the inner bottom surface of the box body 1, and the lifting platform is fixedly connected to the upward movable frame 32. The stepping motor drives the lifting platform to drive the movable frame 32 to move up and down through the transmission mechanism. In this way, the collection bottle rack 34 can be made to approach or move away from the needle holder 31.
[0038] In addition, a controller (not shown) is also fixedly arranged in the box body 1. The controller is electrically connected to the lifting drive, the first selection valve 6 and the second selection valve 35 respectively. The first selection valve 6 and the second selection valve 35 act according to the program set by the controller. The lifting drive is also electrically connected to a plurality of buttons 5.
