Automatic sampling device for sewage treatment and water quality detection

Abstract

The invention provides an automatic sampling device for sewage treatment and water quality detection. The automatic sampling device comprises a containing tank and a water storage tank, wherein the inner part of the containing is hollow; the inner part of the water storage tank is hollow; the left side of the upper end of the containing tank is movable connected with a control button; the middle part of the upper end of the containing tank is tightly connected with a fixed handle; the fixed handle is in a semi-circular shape; a storage battery is arranged at the upper part of the inner part ofthe containing tank. An electric pushing rod is arranged, a movable block is controlled to move vertically through a telescopic rod, and sewage can enter the inner part of the water storage tank through a water inlet pipe by the movable block, so that the sewage can be sampled through an air pressure principle; automatic sampling can be carried out through the electric pushing rod, so that an automatic sampling effect is achieved; the water inlet pipe is arranged and is placed through fixed frames, when bottom sewage requires to be sampled, the automatic sampling device is suitable for the technical field of sewage and has a good development prospect.

Description

technical field [0001] The invention relates to the technical field of sewage, in particular to a sampling device. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage water quality testing is to test the quality of sewage. The sampling device is a water quality sample collection tool with a metal block and acrylic structure; the instrument In line with the national requirements for water environment sampling instruments, the water inlet, water inlet valve and water outlet outlet water closing system are set up; when using this tool for water sample collection, it can go deep into the water at any depth according to the collection needs, and collect any layer in the water water sample. Easy to use and reliable, it is a necessary tool for monitoring and collecting water samples of surface water, ground water, sewage and sea water. [0003] When the exist...
