Multi-stage tube depth sampling device

Abstract

The invention discloses a multi-stage pipe depth sampling device, which is composed of a multi-stage telescopic hydraulic device, a hand pump, a pipe chuck, a sampling main pipe, a tank body, U-shaped bolts, a multi-stage guide pipe and a sampling head. The main pipe is fixed on the wall of the tank body by U-shaped bolts; the sampling head is movably installed inside the sampling main pipe, and is threadedly connected with the multi-stage guide pipe, and the multi-stage guide pipes are also connected by thread, and the pipe chuck is set on the sampling pipe. The top of the main pipe is stuck on the multi-stage guide tube; the hand pump is fixed on the multi-stage guide tube by threaded connection; the multi-stage telescopic hydraulic device is fixed at a specified distance directly above the hand pump. The invention solves the problem that the traditional sampler cannot realize sampling at different depths due to the stirring effect, and the sampling is inaccurate, and can effectively monitor the conditions of media at different depths in the powerful stirring tank. The invention embodies the requirements of rapidity, accuracy, personnel safety and the like of sampling work in large-scale engineering activities.

Description

technical field [0001] The invention relates to a multi-stage tube depth sampling device, in particular to a sampling device for solutions of different depths in a powerful stirring tank. Background technique [0002] The traditional oil tank sampler uses a rope to fix the sampling head and enters samples at different depths by the gravity of the counterweight. However, when sampling in a stirred tank with strong stirring, the rope does not descend vertically due to the turbulent flow of the medium in the tank, and the sampling head cannot reach Accurate sampling at the specified depth, even the rope is in danger of being entangled in the stirring system. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems and provide a multi-stage tube depth sampling device. The present invention performs sampling work of different depths to a reactor with a strong stirring device. [0004] The invention is composed of a multi-s...
