Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to a multi-layer sampling device for a magnetic coagulation sedimentation tank. Background Technology

[0002] Magnetic coagulation sedimentation tanks are a highly efficient water treatment process. By adding magnetic powder, coagulants, and flocculants to the water, the high specific gravity and strong magnetism of the magnetic powder accelerate the formation of denser magnetic flocs from suspended solids, colloids, and other impurities. These flocs are then rapidly separated through sedimentation, significantly improving solid-liquid separation efficiency. These tanks are compact, fast-processing, and produce high-quality effluent. They effectively remove pollutants such as COD, SS, and phosphorus, and are widely used in municipal sewage, industrial wastewater treatment, and greywater reuse. They are characterized by high efficiency, stability, and ease of operation and maintenance. The multi-layer sampling device in the magnetic coagulation sedimentation tank allows for layered water sampling at different depths and areas within the tank, accurately acquiring water quality data at each stage to aid in the analysis of coagulation and sedimentation effects. The tanks are simple in structure, easy to operate, and ensure accurate monitoring.

[0003] Publication No. "CN219608500U" discloses a multi-layer sampling device for a magnetic coagulation sedimentation tank. The device includes a vertical plate, multiple sampling bottles, a sliding assembly connecting the vertical plate to each sampling bottle, and an adjusting assembly. The sliding assembly includes sliding blocks disposed on the outer wall of each sampling bottle. Multiple sliding blocks are arranged along the length of the vertical plate, and the vertical plate has sliding grooves for the sliding blocks to slide along its length, with the height of the grooves greater than the thickness of the sliding blocks. The sampling bottles are used for water sampling within the magnetic coagulation sedimentation tank. The adjusting assembly drives the multiple sliding blocks to move synchronously along the sliding grooves. This designed multi-layer sampling device for a magnetic coagulation sedimentation tank, through the sliding connection between the sliding rod and the vertical plate, facilitates the adjustment of the sampling bottles to different heights, thereby enabling water sampling at different heights within the magnetic coagulation sedimentation tank and improving the sampling effect of the multi-layer sampling device.

[0004] Although the above-mentioned utility model facilitates the adjustment of the sampling bottle to different heights, thereby enabling water sampling at different heights in the magnetic coagulation sedimentation tank and improving the sampling effect of the multi-layer sampling device in the magnetic coagulation sedimentation tank, the sampling bottle is connected to the sliding groove of the vertical plate via a sliding block, and the sliding block is fixed to the sliding rod. The bottle cap is also connected to the adjusting rod via a guide rod. The components are mutually constrained, and no convenient disassembly structure is provided, making it difficult to remove the sampling bottle from the vertical plate separately. This makes it inconvenient to clean and replace the bottle and transfer the water sample after sampling. Utility Model Content

[0005] In response to the problems mentioned in the background art, the purpose of this utility model is to provide a multi-layer sampling device for a magnetic coagulation sedimentation tank, so as to solve the problem that the sampling bottle is connected to the sliding groove of the vertical plate by the sliding block and the sliding rod is fixed, and the bottle cap is connected to the adjusting rod by the guide rod. The components are mutually restrained and no convenient disassembly structure is set up, which makes it difficult to remove the sampling bottle from the vertical plate individually, and it is inconvenient to clean and replace the bottle and transfer the water sample after sampling.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A multi-layer sampling device for a magnetic coagulation sedimentation tank includes a horizontal plate, a vertical plate fixedly connected to the bottom of the horizontal plate, a movable seat slidably connected to one side of the vertical plate, three movable seats, positioning components symmetrically installed on one side of the movable seats, a fixed column fixedly connected to one side of the movable seat, a fixed ring fixedly connected to the other end of the fixed column, a fixed frame fixedly connected to the top of the fixed column, a connecting frame rotatably connected to one side of the fixed frame via a rotating shaft, a top cover fixedly connected to the other end of the connecting frame, a servo motor installed on one side of the fixed frame, the output end of the servo motor fixedly connected to the rotating shaft, a sampling bottle movably connected inside the fixed ring, an installation ring fixedly sleeved on the outside of the sampling bottle, and fixing components symmetrically installed at the bottom of the fixed ring. The fixing assembly includes a cavity, a first return spring, a movable plate, a push block, and a locking block. Assembly blocks are symmetrically fixedly connected to the bottom of the fixing ring. A cavity is formed inside each assembly block. A first return spring is symmetrically fixedly connected to one side of the cavity, and a movable plate is fixedly connected to the other end of the first return spring. The movable plate is slidably connected to the cavity. Push blocks and locking blocks are fixedly connected to the other side of the movable plate. The other end of the push block extends outward from the outside of the fixing ring, and the other end of the locking block extends outward from the outside of the assembly block. Assembly grooves are symmetrically formed at the top of the mounting ring. The assembly block and the assembly groove are inserted into each other. A locking slot is formed on one side of the assembly groove, and the locking block and the locking slot are engaged. This allows the sampling bottle to be removed from the device, greatly facilitating water sample transfer. Different levels of water samples can be quickly dispensed into the testing container. Furthermore, disassembly allows for thorough cleaning of the bottle's interior, ensuring no contaminants interfere with the next sampling, guaranteeing the accuracy of water sample testing, and significantly improving the convenience and reliability of the sampling operation.

[0007] As a preferred technical solution, the positioning component includes a receiving cavity, a second return spring, a movable plate, a connecting column, a pull handle, and a positioning column. A fixed block is symmetrically fixedly connected to one side of the movable seat. The receiving cavity is opened inside the fixed block. A second return spring is fixedly connected to one side of the receiving cavity. The other end of the second return spring is fixedly connected to the movable plate, which is slidably connected to the inside of the receiving cavity. A connecting column is fixedly connected to the other side of the movable plate. The other end of the connecting column extends out of the outside of the fixed block and is fixedly connected to the pull handle. The second return spring is sleeved on the outside of the connecting column. A positioning column is fixedly connected to the other side of the movable plate. Positioning holes are symmetrically opened at equal intervals on one side of the vertical plate. The positioning column and the positioning holes are plugged in, which can flexibly adapt to the sampling needs of different depths in the magnetic coagulation sedimentation tank. Whether it is the upper primary sedimentation zone, the middle flocculation reaction zone, or the lower sludge zone, water samples can be accurately collected from the corresponding positions, avoiding sampling deviations caused by fixed height limitations and improving the adaptability of the sampling device.

[0008] As a preferred technical solution, a sliding groove is symmetrically opened on one side of the vertical plate, and a sliding block is symmetrically fixedly connected on one side of the movable seat. The sliding block and the sliding groove are slidably connected. The sliding block and the sliding groove are T-shaped. The T-shaped sliding groove of the vertical plate and the T-shaped sliding block of the movable seat cooperate to slide smoothly and connect firmly, which can effectively prevent the movable seat from falling off and ensure stable adjustment during sampling.

[0009] As a preferred technical solution, sealing gaskets are glued to the bottom of the top cap and the top of the sampling bottle. The sealing gaskets are made of rubber material, which can fit tightly to form an effective seal, preventing water sample leakage or external impurities from entering during sampling, ensuring the purity of the water sample. In addition, the rubber material has good elasticity and long-lasting sealing performance, improving the reliability of sampling.

[0010] In summary, the present invention has the following main advantages: First, in this utility model, pressing the button causes the moving plate to drive the locking block to press against the first return spring, compressing the first return spring and simultaneously retracting the locking block into the cavity. Then, the sampling bottle is inserted into the fixing ring from the bottom, causing the mounting ring and the fixing ring to merge. At the same time, the assembly block is inserted into the assembly groove. Then, the button is released, the first return spring resets, the moving plate springs back, and the locking block pops out. The locking block engages and fixes with the slot, completing the installation of the sampling bottle. The sampling bottle can be removed from the device, greatly facilitating water sample transfer. Different levels of water samples can be quickly dispensed into the testing container. At the same time, after disassembly, the inside of the bottle can be thoroughly cleaned to ensure that there are no contaminants interfering with the next sampling, ensuring the accuracy of water sample testing and significantly improving the convenience and reliability of sampling operations. Secondly, in this utility model, pulling the handle outward causes the connecting column to move the movable plate and the positioning column. The movable plate presses against the second return spring, compressing the second return spring. At the same time, the positioning column retracts into the receiving cavity. Then, pushing the movable seat causes the movable seat to slide the sliding block inside the sliding groove. After adjusting the movable seat to the appropriate position, releasing the handle resets the second return spring. The movable plate rebounds, causing the positioning column to pop out and engage with the positioning hole, thus completing the adjustment of the sampling bottle height. This allows for flexible adaptation to sampling needs at different depths in the magnetic coagulation sedimentation tank. Whether it is the upper primary sedimentation zone, the middle flocculation reaction zone, or the lower sludge zone, water samples can be accurately collected from the corresponding locations, avoiding sampling deviations caused by fixed height limitations and improving the adaptability of the sampling device.
