Fixed-point collector for sludge sample in fermentation tank and sampling method

Abstract

The invention discloses a fixed-point collector for a sludge sample in a fermentation tank and a sampling method. In a conventional sludge fermentation experiment or production process, as different microenvironments are possibly caused at different positions inside the fermentation tank, the monitoring result of a conventional collector is not accurate. The fixed-point collector for the sludge sample in the fermentation tank comprises a tip sampling pipe, wherein the tip sampling pipe is connected with a lengthening pipe; the lengthening pipe is connected with an arm pipe; a first control rod fixing strip is mounted inside the tip sampling pipe; a second control rod fixing strip is mounted inside the lengthening pipe; the first control rod fixing strip is fixedly connected with a tip sampling pipe control rod; the second control rod fixing strip is fixedly connected with a lengthening pipe control rod; the lengthening pipe control rod is in a hollow tubular shape; the tip sampling pipe control rod passes through the interior of the lengthening pipe control rod, and is inserted into the tip sampling pipe. The sampling analysis position of the fixed-point collector for the sludge sample in the fermentation tank and the sampling method is changeable; the complete analysis on a fine microenvironment in a whole tank body is realized.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a fixed-point collector for sludge samples in a fermentation tank and a sampling method. Background technique [0002] In the conventional sludge fermentation experiment or production process, monitoring the fermentation of the fermentation substrate in the tank is beneficial to the research of the fermentation process and the control of the fermentation conditions. In actual operation, samples are usually collected through the discharge port or a fixed sampling port, but different positions inside the fermenter may cause different microenvironments, especially for those that lack stirring devices or are not stirred uniformly. For fermenters, the difference in local fermentation level caused by the difference in location is more obvious. Therefore, the existing fixed-position sampling analysis has not made a comprehensive analysis of the fine microenv...

Problems solved by technology

In actual operation, samples are usually collected through the discharge port or a fixed sampling port, but different positions inside the fermenter may cause different microenvironments, especially for those that lack stirring devices or are not stirred uniformly. For fermentation tanks, the difference in local fermentation level caused by the difference in location is more obvious

Therefore, the existing fixed-position sampling analysis has not made a comprehensive analysis of the fine microenvironment in the entire tank due to the single position.
