Description

Sump oil pond sedimentary deposit sampler

Technical Field

The invention relates to a sampler for a sediment layer at the bottom of a dirty oil tank.

Background

The large-scale dirty oil pool in the industries of oil fields and the like stores liquid media such as dirty oil and sewage for a long time, and a deposition layer can be gradually formed at the bottom of the pool. The deposit layers need to be sampled periodically for assay analysis so as to grasp the deposit rule of the sump and take dredging technical measures. Because divers are difficult to descend to the bottom of a large-scale sewage tank to sample manually, sediment sampling can only be carried out on the upper part of the sewage tank through a special sampler.

At present, the sediment or silt sampler cannot adopt a container sampler for sampling liquid, but only adopts a sampler with a cartridge structure with a larger lower end opening, the sediment or silt is inserted into the cylindrical insertion tube, the insertion tube is filled with the sediment or silt, and then the sediment or silt is pulled out, so that the sediment or silt is brought out. For example: patent CN111257060a discloses a tank bottom sediment cartridge sampler, patent CN110296858A discloses a device for collecting and sampling sludge and mucky soil samples, patent CN208012900U discloses a handheld underwater sludge sampler, and patent CN208012902U discloses an underwater sludge sampler. Although the lower end opening of the sampler is larger, the sampler is convenient to be inserted into sediment or silt for sampling, the lower end is not plugged after sampling is finished, and sediment or silt easily flows out from the lower part in the lifting process of the sampler, so that sampling failure is caused.
