Description

Technical Field

[0001] The present invention relates to the technical field of wastewater detection, and in particular to a wastewater sampling device for pharmaceutical production. Background Art

[0002] Pharmaceutical industrial wastewater refers to wastewater discharged from factories producing antibiotics, antimicrobials, antisera, and other organic and inorganic pharmaceuticals. The volume and quality of this wastewater vary depending on the type of pharmaceutical produced. In addition to animal-derived wastewater (primarily animal organs) and plant-derived wastewater (primarily herbal medicines), antibiotic and antisera production wastewater generally contains toxic substances such as fluorine, cyanide, phenol, cresols, and mercury compounds. It also contains high levels of biochemical oxygen demand (BOD), chemical oxygen demand (COD), and colloidal substances. Pharmaceutical wastewater cannot be directly treated biochemically due to its high levels of recalcitrant organic matter, salt, and ammonia nitrogen. It must be removed early in the process, and the concentration of ammonia nitrogen is difficult to control and is highly unstable.

[0003] Existing methods for sampling pharmaceutical wastewater typically involve manual field sampling, labeling, and laboratory testing. These samples are typically collected using standard sampling bottles, which only capture the top layer of water and are unable to capture water at different depths. This difference in water quality can affect subsequent wastewater testing results. Therefore, a pharmaceutical wastewater sampling device is needed that can collect samples at different depths.

[0028] Specifically, the positioning and clamping mechanism includes two clamping plates 21 symmetrically arranged on both sides of the through-hole 15. The clamping plates 21 are fixedly connected to the first slider 23 via a first connecting rod 22. The first slider 23 is slidably connected to the guide rail 24. The first slider 23 is fixedly connected to the drive nut 25. The two drive nuts 25 are respectively arranged on two opposite threads of a bidirectional screw 26. The bidirectional screw 26 is fixedly connected to the movable end of the drive motor 27.

When it reaches the preset depth, the second rope reel 14 stops working, the top cover 3 no longer falls, the first rope reel 11 continues to release the first hinge rope, and the container 2 continues to fall. At this time, since the gravity of the container 2 and the counterweight block 12 is greater than the attraction between the first magnet 5 and the second magnet 7, the container 2 and the sealing ring 6 are separated, and water enters the container 2 from the grid hole 8 and the opening of the container 2. After the sampling is completed, the first rope reel 11 rewinds the first hinge rope to the state when the second rope reel 14 stops working. At this time, the container 2 and the sealing ring 6 are in contact and sealed. The first rope reel 11 and the second rope reel 14 work synchronously again to retract the sampler between the two splints 21;

[0035] (2) The driving motor 27 drives the bidirectional screw 26 to rotate, and the bidirectional screw 26 drives the two driving nuts 25 to move closer to the sampler, and the two clamping plates 21 clamp the sampler;

[0036] (3) The electric push rod 31 pushes the fixed plate 28 and the sampling needle 17 toward the sampler in the clamped state until the front needle of the sampling needle 17 is inserted from the rubber ring 16. The sampling pump 18 is turned on to absorb the water sample, and the water sample is controlled to enter the water quality detection unit 20 through the multi-way solenoid valve 19, and the water quality is tested through the water quality detection unit 20.

[0037] The pharmaceutical production wastewater sampling device of the present invention uses a winch and a specially designed sampler to collect water samples at a specific depth within a water area.
