Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a biological pool sampling rapid filtering device. Background Art

[0002] The core function of the biological pool is to use the beneficial microorganisms in it to treat sewage. These microorganisms can effectively absorb harmful substances such as heavy metal ions and nutrients in the sewage, making the sewage cleaner and speeding up the purification of sewage. Usually, staff need a sampling and filtering device to extract the liquid in the biological pool to detect the content of substances in the sewage.

[0003] After searching, a Chinese patent discloses a filtering sampling device for biological fermentation (authorization announcement number: CN221501073U), comprising a filter tube, a filter plate and a fixed block, wherein a sampling tube is provided at the bottom of the filter tube, and a connecting ring is fixedly connected to one end of the filter tube near the sampling tube. When the liquid flows, it passes through the filter plate, and the filter plate filters out the floating foam on the liquid. After sampling is completed, the discharge pipe is opened and the sampling rod is pushed toward the filter plate to discharge the extracted liquid from the discharge pipe. When the filter plate needs to be cleaned, the filter tube is rotated. When the limiting plate is not engaged with the limiting groove, the filter tube can be lifted up to separate the filter tube from the sampling tube, and the fasteners on the filter plate can be removed to clean the filter plate. The filter plate can be used to filter out floating foam in the sample, thereby improving the sample accuracy. At the same time, the cooperation of multiple components can make the filter plate easier to load and unload, thereby improving the cleaning efficiency.

[0004] In actual application, the patented technology can extract liquid from the biological pool and filter it for subsequent testing. However, during use, the top plate and the sampling rod are structurally arranged in the above scheme and cannot be disassembled, so it is inconvenient for the staff to clean the upper interior of the sampling tube, as well as the connection between the sampling rod (2) and the sampling tube and the bottom. Therefore, incomplete cleaning may occur, resulting in residual liquid deterioration, which contaminates new liquid during the next sampling. At the same time, the filter plate of the above scheme is arranged above the filter tube, so it is inconvenient for the staff to remove and install the filter plate. In addition, the working principle of the above scheme states that the extracted liquid can be discharged from the discharge pipe by pushing the sampling rod toward the filter plate. However, in the above scheme, when the top position of the sampling rod exceeds the discharge pipe, the liquid cannot be discharged, thereby greatly reducing the use effect of the device.
