The bottom of the tank body extends to the interior of the tank for 15 centimeters, a piston is arranged in the sampling main pipeline, and the exterior of the sampling main pipeline is connected by a lead screw; the bottom is provided with an open branch pipe for sampling. The process of sample drives the piston through the lead screw and removes to the outside, forms the negative pressure in the trunk line, and the piston removes to branch pipe department, and the branch pipe is squeezed into to the material in the jar under the effect of internal pressure to flow out, reach the sample purpose. The problem of jar body bottom deposit has been solved to a certain extent to this scheme, but if bold material blocks up inside sample connection, still can't be with the material suction under the effect of piston. Meanwhile, after a certain time, the sealing performance of the piston is reduced, and materials easily overflow from the abrasion part of the piston in the sampling process, so that the environmental pollution is caused. Compared with the traditional sampling mode, the scheme of the patent still only arranges the sampling port at the bottom of the tank body, and for the high-concentration anaerobic fermentation tank, the analysis result is not representative compared with the integral level of the materials in the tank body.

Example 1
As shown in fig. 1-4, the present embodiment provides a sampling system suitable for a dry anaerobic fermentation tank, comprising a sampler and a plurality of sampling pipes 1, wherein the sampling pipes 1 are sequentially arranged on the top of the dry anaerobic fermentation tank 2 along the direction from the feeding end to the discharging end of the dry anaerobic fermentation tank 2, and a sealing cover 3 is arranged on the sampling port of the sampling pipe 1; the sampler includes that a plurality of can dismantle the connecting rod 4 of connection, and wherein the tip of the connecting rod 4 of lowest end is provided with sample chamber 5, and wherein sample chamber 5 is the commonly used sampling device in this field, and it is no longer repeated here.
Four sampling pipelines 1 are arranged in the top of the dry anaerobic fermentation tank 2 along a straight line from the feeding end at the head end of the tank body to the discharging end at the tail end of the tank body. This is so arranged that: due to the relatively high concentration of materials in dry anaerobic fermentation and the degradation effect of microbial bacteria, the concentration gradient of the materials in the tank from the feeding end to the discharging end occurs, and the degradation conditions of the materials at different positions are different. This embodiment can carry out the segmentation sample through set up four sampling pipeline 1 on dry-type anaerobic fermentation jar 2, can more comprehensively analyze the interior bacterial colony of jar and the stage characteristic of material degradation. Because the sampling pipeline 1 is arranged at the top of the tank body, the situation that the sampling pipeline is blocked due to the deposition of interferents in the traditional fermentation container does not exist.
