Flip-cover solid-liquid mixture sampler for biogas digester

Abstract

The invention discloses a flip-cover solid-liquid mixture sampler for a biogas digester; the flip-cover solid-liquid mixture sampler comprises a sampling tube and a sampling tube rope that is connected with the same. The sampling tube rope is fitted with a floater. The sampling tube includes a sampling chamber, a sampling port, a piston and a piston rod, one side of the piston rod is connected with a piston pull rope, the other side of the piston rod is connected with the piston, the piston is positioned in the sampling chamber, the sampling chamber is connected with the sampling port, an opening of the sampling port is fitted with a seal cover that is fitted with a seal cover that is rotationally flappable inside, the sampling tube is fitted with a shielding cover that is rotational, the shielding cover is positioned at the sampling port and is connected with the pull rope, and the pull rope includes a first pull rope and a second pull rope. The flip-cover solid-liquid mixture sampler is simple to implement and convenient to operate, allows a liquid sample of specified depth to be accurately acquired, and helps reduce sample loss or contamination and improve sample quality and accuracy.

Description

technical field [0001] The invention relates to the field of biogas sample sampling, in particular to a flip-type biogas digester solid-liquid mixture sampler. Background technique [0002] In hydrogeology, it is often necessary to detect the composition of groundwater, such as iron, fluorine, zinc, copper, chromium, manganese, iodine, molybdenum, cobalt and other elements in the water. These elements are necessary for the human body and are very important for the normal metabolism of life. Many endemic diseases are caused by people drinking substandard water for a long time, such as dental fluorosis caused by high fluoride water, big neck disease caused by low iodine water, and skin cancer caused by high arsenic water. At present, the groundwater collection method is to use a wide-mouth bottle to collect directly in the port where the liquid flows out or in the liquid pool. Since the liquid composition at different depths may be different in the same liquid pool, it is nece...

Problems solved by technology

At present, the groundwater collection method is to use a wide-mouth bottle to collect directly in the port where the liquid flows out or in the liquid pool. Since the liquid composition at different depths may be different in the same liquid pool, it is necessary to use wide-mouth bottles to collect different depths in stages. The liquids at different depths are numbered for distinction, and finally the numbered liquids are tested separately to obtain the composition of the liquids at different depths. The collection process of this groundwater collection method is very complicated and the collection efficiency is low.

[0003] Ordinary liquid sample sampling tools are not suitable for sealed sampling of samples with special odor or poisonous, waterproof and anti-pollution. The old sampling method is generally a rotating open sampling tube warehouse, which has poor sealing effect and is easy to cross. Pollution, inconvenient to carry, limited on-site use, etc. Digester smell is unpleasant and may be fatal if inhaled for a long time

In summary, the above situation brings great difficulties to the analysis work. On the one hand, it causes sample cross-contamination and poor sealing effect; on the other hand, it is not easy to carry and fix, and there are safety issues

[0004] By searching the patent database, such as: anti-pollution liquid sampler CN2888436Y, closed liquid gas sampler CN2786600Y, a new type of liquid sample sealed sampling box CN205580783U, a liquid sampler CN205449566U, a liquid pressure maintaining sampling cylinder CN104792578A, liquid separation Layer sampling sealing device CN204964252U, a closed liquid sampler CN201852720U, negative pressure liquid sampler CN201837544U and other patents, it is found that the structure of the existing sampler is relatively complicated, and it is not easy to carry, and it is difficult to extract accurately when using Samples specified in different locations, and the extracted samples are easy to be lost or polluted, and the quality cannot be guaranteed
