Liquid sampling device capable of buoyancy stratified sampling and automatic cleaning for chemical industry

Abstract

The invention discloses a liquid sampling device capable of buoyancy stratified sampling and automatic cleaning for chemical industry. The device comprises a movable frame, a threaded layer, a smart sampling device, a device casing and a motor frame, a pulley at the lower portion is rolled and rotated with the rotation of a belt pulley to allow a pipeline at the internal portion to displace downwards through an assembling rack, and when the pipeline is fell off, an output rack at the internal portion of the installation rack is employed to perform regulation of the stressed area of the deviceand the internal air pressure so as to allow the pipeline to follow lifting or declining and perform movable sampling working for the liquid with different liquid levels at the internal portion, afterthe device sampling is completed, the reverse rotation of the belt pulley at the internal portion is performed to perform lifting of the pipeline, the matching rack and a strike-off rack at the internal portion thereof are employed to perform liquid strike-off backflow work of the surface of the pipeline, and when the belt traction is performed, the internal friction layer can perform liquid scrubbing work at the surface of the pipeline so as to avoid the condition that the liquid dropping of the pipeline influences the working environment.

Description

technical field [0001] The invention relates to the field of industrial sampling, in particular to a liquid sampling device for chemical industry which uses buoyancy layered sampling and can be automatically cleaned. Background technique [0002] The usual industrial liquid sampling device is sent into the container where the liquid is accumulated through a soft hollow pipe, and then the liquid inside the container is pressed out by means of negative pressure, thus completing the liquid sampling work inside the container, but in this way The way: [0003] When performing sampling work, when liquid sampling is performed through a hollow pipe, the position where the internal liquid is sucked out is basically the same liquid level height, and it is impossible to perform separate sampling work according to the deposition ratio of liquids at different liquid levels inside the container. After the internal liquid is removed, when the pipeline is recovered, due to the loss of nega...

Problems solved by technology

[0003] When performing sampling work, when liquid sampling is performed through a hollow pipe, the position where the internal liquid is sucked out is basically the same liquid level height, and it is impossible to perform separate sampling work according to the deposition ratio of liquids at different liquid levels inside the container. After the internal liquid is recovered, when the pipeline is recovered, because of the loss of negative pressure traction, the liquid inside the adhered container will drip outward from the pipeline, which will easily cause the internal liquid to scatter and affect the working environment
