Abstract
Description
Technical Field
[0001] This utility model belongs to the field of industrial wastewater sampling technology, and specifically relates to a stratified sampling device for wastewater treatment ponds. Background Technology
[0002] Vertical stratification often occurs in industrial wastewater treatment ponds due to differences in pollutant density, solubility, and reactivity. For example, oil may float, heavy metals may settle, or anaerobic / aerobic reaction zones may be distributed. Traditional mixed sampling can mask these stratification characteristics, while stratified sampling can accurately reflect the distribution patterns of pollutants at different depths, providing key data support for process control. Especially for industrial wastewater containing volatile organic compounds, settling particles, or significant biochemical reaction gradients, stratified monitoring has become a mandatory requirement of environmental standards.
[0003] Traditional stratified sampling devices for wastewater treatment ponds agitate the water during descent, causing mixing of wastewater from different layers. Once the target depth is reached, it becomes impossible to accurately isolate the current water layer. During sampling, cross-contamination between upper and lower layers is common, and the sample is further mixed with impurities from other water layers during the lifting process, ultimately leading to distorted test data. In addition, the fixed-length sampling rod cannot be adapted to wastewater ponds of different depths. If it is too short, it cannot collect deep samples, and if it is too long, it causes operational redundancy. When dealing with treatment ponds of varying depths, it is necessary to repeatedly purchase equipment of different specifications, increasing costs.
[0004] To address the issues mentioned in the background above, a stratified sampling device for wastewater treatment ponds is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a stratified sampling device for wastewater treatment ponds, which has the advantages of simple operation and high adaptability.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stratified sampling device for a wastewater treatment tank, comprising a main component, a rotating cylinder I rotatably sleeved inside the main component, an extension component provided at the bottom of the main component, a rotating cylinder II rotatably sleeved inside the extension component, a slot provided at the center of the bottom of the rotating cylinder I and the rotating cylinder II, a locking rod bolted to the center of the top of the rotating cylinder II, and the surface of the locking rod sleeved inside the top slot, a sampling groove provided inside the rotating cylinder II, a sampling port II provided on the left side of the top of the sampling groove, a sampling port I provided in the middle of the right side of the extension component, and an extension mechanism provided at the top of both sides of the extension component.
[0007] Using the above technical solution: When stratified sampling of the wastewater treatment tank is required, first determine the number of layers to be sampled. For each layer, set up an extension device. After the device is extended, fix one end of the rope to the hanging ring rope, and fix the other end of the rope to the fixed rod next to the wastewater treatment tank. After placing the device in the wastewater tank, hold the top of the main component with one hand and the top of the rotating drum with the other hand to rotate it. The rotation of the drum drives the slot, which in turn drives the locking rod to rotate, which in turn drives the rotating drum to rotate. After the first and second markers are aligned, sampling ports one and two are connected. Wastewater enters the sampling port from sampling port one. Second, enter the sampling tank through sampling port two. After sampling, rotate drum one to disconnect sampling port one and sampling port two, sealing the sampling tank. Take the device out of the wastewater treatment tank and test the wastewater in each sampling tank of the extended drum two. Keep the device sealed while it sinks to avoid mixing wastewater from different water layers. After reaching the target depth, open the sampling port by rotating it to collect only the wastewater of the current layer. After sampling, rotate it again to close it, ensuring that the sample is not contaminated by other water layers during the lifting process. The operation is simple and ensures the accuracy of the sampling data. It is especially suitable for industrial wastewater scenarios that require strict stratified monitoring.
[0008] The present invention is further configured such that the extension mechanism includes a bracket, the bracket is bolted to the top of both sides of the extension member, the front end and the rear end of the bracket are hinged with hooks, and the bottom of both sides of the main member and the extension member are bolted with hooks, and the top of the inside of the hooks is engaged with the inside of the top hooks.
[0009] The above technical solution employs an extension mechanism. When stratified sampling of a wastewater treatment tank is required, the number of sampling layers is first determined. For each layer, an extension component is installed. A new extension component is taken out, and its positioning rod and locking rod are inserted into the positioning groove and locking groove of the bottom extension component connected to the device. The hook of the new extension component is then hooked into the hooks on both sides of the bottom extension component connected to the device for secure fixing. After the extension components for the required number of layers are connected to the main component, sampling can begin. This system can accurately match the structure of wastewater tanks at different depths. By adding extension components section by section, operators can quickly construct a sampling system that matches the tank depth. Each meter of extension forms an independent sampling unit, ensuring strict isolation of samples from each water layer. This not only meets the needs of shallow sampling but also addresses deep tank conditions through the stacking of extension components, significantly improving the adaptability of the device. It is particularly suitable for industrial scenarios with large depth fluctuations or requiring multi-point comparative monitoring, significantly reducing the cost of repeated equipment purchases while ensuring data accuracy.
[0010] The present invention is further configured such that positioning grooves are provided on both sides of the bottom of the main component and the extension component, and positioning rods are bolted to both sides of the top of the extension component, and the interior of the positioning groove is sleeved with the surface of the positioning rod.
[0011] The above technical solution is adopted: by setting a positioning rod and a positioning groove, positioning can be convenient, and the main component can remain stationary while the second rotating drum rotates.
[0012] The present invention is further configured such that a mark one is bolted to the left side of the top of the main component, and a mark two is bolted to the top of the surface of the rotating cylinder.
[0013] The above technical solution is adopted: by setting mark one and mark two, the displacement of sampling port one and sampling port two can be observed when rotating drum one and drum two. Mark two is in the same direction as sampling port one, and mark one is in the same direction as sampling port two.
[0014] The present invention is further configured such that the hook is an elastic element.
[0015] By adopting the above technical solution, the hook can be made elastic by setting it as an elastic element, making it easy to slip onto the hook and snap it in place.
[0016] The present invention is further configured such that the height of the extension member is one meter.
[0017] Using the above technical solution: by setting it to one meter, there can be one spacing every meter.
[0018] The present invention is further provided that the top of the surface of the main component is provided with anti-slip texture.
[0019] The above technical solution, by setting anti-slip texture, can prevent slipping.
[0020] The present invention is further configured such that a hanging ring is bolted to the top of the rotating drum.
[0021] The above technical solution, by setting up a hanging ring, makes it easy to fix the device.
[0022] In summary, this utility model has the following beneficial effects:
[0023] 1. This utility model maintains a sealed state during the sinking of the device to avoid mixing of wastewater from different water layers. After reaching the target depth, the sampling port is opened by rotation to collect only the wastewater of the current layer. After sampling, it is closed by rotation again to ensure that the sample is not contaminated by other water layers during the lifting process. The operation is simple and ensures the accuracy of the sampling data. It is especially suitable for industrial wastewater scenarios that require strict stratified monitoring.
[0024] 2. This utility model can accurately match the structure of wastewater pools of different depths. By adding extension parts section by section, operators can quickly build a sampling system that matches the pool depth. Each extension meter forms an independent sampling unit, ensuring that samples from each water layer are strictly isolated. It not only meets the needs of shallow sampling, but also can cope with deep pool conditions by adding extension parts, greatly improving the adaptability of the device. It is especially suitable for industrial scenarios with large depth fluctuations or multiple points of comparative monitoring. While ensuring data accuracy, it significantly reduces the cost of repeated equipment purchases. Attached Figure Description
