AI Technical Summary
During the unloading process of liquid hazardous chemicals, the second sampling operation is inconvenient and there are safety hazards. Especially because the liquid level is low, the arm needs to be extended into the tank to take samples, and the liquid hazardous chemicals attached to the outer wall of the sampling tube are prone to burn the operator.
A liquid hazardous chemical tanker sampling device is designed, including an L-shaped mounting seat and a hand pump housing, a connection port and installation port connected through a gas channel, and a sampling tube with a scraping sleeve and a marking line. The hand pump generates negative pressure for sampling, and the attached liquid hazardous chemicals are scraped off under the action of the scraping sleeve through the pull-up sampling tube.
The position of the sampling tube is adjusted according to the liquid level height, without the need for an arm to extend into the tank to take samples, making the operation more convenient; at the same time, the liquid hazardous chemicals attached to the outer wall of the sampling tube are scraped away through the scraping sleeve, which improves sampling safety and avoids the risk of burning the operator's arms.
