Multitube barium sulfate solution sampling device

Abstract

The invention discloses a multitube barium sulfate solution sampling device. The device is used by arranging a pipette on the lower end of a front protraction frame by operating staff before use, connecting with an air suction pipe through a through hole inside the front protraction frame, then rotating a rotating pressure rod to check whether an air bag has air leakage conditions, then rotating the rotating pressure rod to lead an extrusion plate to compress the air bag so as to exhaust internal air, inserting the pipette into a sodium sulfate solution and then reversely rotating the rotating pressure rod to lead the sodium sulfate solution to enter in the pipette, observing the height of liquid in the pipette until the required amount is achieved, and holding a lifting handle so as to lead the pipette to leave away the sodium sulfate solution, until the device completes the working process. The device can safely and reliably draw sodium sulfate solution for experiments, the efficiency is high, the clean working environment can be helpfully maintained, and the physical power consumption of the operating staffs can be reduced.

Description

technical field [0001] The present invention relates to a barium salt sampling device. Background technique [0002] In actual production or scientific experiments, it is often necessary to obtain liquid samples for production inspection and identification analysis. When taking liquid from the sodium sulfide liquid storage tank, due to the large storage capacity of the liquid storage tank, the concentration of the solution at different depths of the liquid storage tank is uneven, and the solute is easy to crystallize and sink to the bottom. At this time, it is necessary to take liquid in layers. Sampling is required multiple times, and often the samples taken do not meet the requirements. [0003] In order to solve the above problems, the patent document whose publication number is CN203981450U discloses a kind of integrated layered sampler for sodium sulfide detection. There are at least two barrels, equidistantly distributed on the handle, the sampling barrel and the han...

Problems solved by technology

The liquid taker adopts a single-press switch structure, and the valve head and the valve seat have high requirements for cooperation. The assembly is not good or it has been used for a long time, resulting in easy leakage; in addition, the control frame is made of elastic materials, which is easy to age, especially in winter. The temperature is low, the bottle body and the control frame are hardened, it is difficult to squeeze, and it is inconvenient to take the liquid

In addition, there is no working instruction on the liquid taker, it is not suitable for use in the dark, and it also gives people a cold feeling, and the function is monotonous
