Description

Technical Field

[0001] This utility model relates to the technical field of water quality monitoring equipment, specifically a sampling device suitable for reaction sedimentation tanks. Background Technology

[0002] A reaction sedimentation tank is a technical device used for water treatment, mainly for removing suspended solids and impurities from water. By adding flocculants to the water, suspended particles collide and agglomerate to form larger particles, which are then separated from the water by gravity sedimentation, thus achieving preliminary water treatment. In order to monitor the quality of the treated water, it is usually necessary to sample and test the treated water.

[0003] However, in the traditional design of sampling at the outlet of the sedimentation tank in water purification facilities, the sampling structure is designed below the outlet pipe. In actual use, because the outlet pipe of the sedimentation tank cannot be kept full of water, it is impossible to collect water samples that meet the requirements in a timely manner through the sampling structure at the outlet pipe. This often leads to water shortage in the monitoring instruments, thus affecting the stability of water sample monitoring. In addition, the number and locations of existing sampling structures are limited, and the sampling points are not evenly distributed. This makes the water samples collected by the sampling structure unrepresentative, and it can also cause the phenomenon that water quality deterioration in some areas cannot be detected in time, which has a great impact on the stable operation of the subsequent system. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device suitable for reaction sedimentation tanks, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampling device suitable for a reaction sedimentation tank, comprising a sampling bucket, the sampling bucket being welded to the drain outlet of a water collection tank, a baffle plate being fixedly connected at the junction of the sampling bucket and the top of the water collection tank, an inclined tube penetrating the bottom end of the sampling bucket, a mixing tank being fixedly connected to the bottom end of the inclined tube, a vertical cylinder penetrating the middle of the bottom end of the mixing tank, an outlet pipe penetrating the bottom end of the vertical cylinder, a solenoid valve being fixedly installed at the end of the outlet pipe, a liquid level sensor being installed at the top of the outlet pipe, a sampling tube penetrating the bottom of the outlet pipe, and a needle valve being installed in the middle of the sampling tube.

[0006] Preferably, a protective net cover is provided on one side of the water baffle, and the protective net cover is connected to the sampling bucket cover through the water baffle.

[0007] Preferably, the water collection tank, the sampling bucket, and the mixing tank are all located inside the sedimentation tank, and a pre-embedded sleeve is inserted through one side wall of the bottom of the sedimentation tank, and the outlet pipe is connected to the sedimentation tank through the pre-embedded sleeve.

[0008] Preferably, a bracket is fixedly connected to the inner wall of the vertical cylinder, and a vertical rod is rotatably connected to the middle of the bracket.

[0009] Preferably, an agitator blade is fixedly connected to the top end of the vertical rod, and a turbine blade is fixedly connected to the bottom end of the vertical rod, with the turbine blade located inside the vertical cylinder.

[0010] Preferably, the solenoid valve is electrically connected to the liquid level sensor.

[0011] Preferably, the sampling hopper is connected to the interior of the water collection tank, the sampling hopper is connected to the interior of the mixing tank through an inclined tube, and the sampling tube is connected to the interior of the mixing tank through an outlet tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This sampling device, applicable to reaction sedimentation tanks, uses a baffle plate and inclined tube to allow the sampling hopper to directly sample at the outlet of a water collection tank with a large water flow. This allows the water after the reaction in the sedimentation tank to directly enter the sampling structure. At the same time, the baffle plate ensures that as much water as possible flows from the water collection tank into the sampling hopper. Furthermore, when the water source in the outlet pipe is low, the water in the outlet pipe can be controlled to flow into the sampling pipe in a concentrated manner through the cooperation of a liquid level sensor and a solenoid valve, thereby ensuring that the sampling pipe is always full of water, which helps to improve the timeliness and stability of water sample collection and monitoring.

[0014] 2. This sampling device, applicable to reaction sedimentation tanks, utilizes sampling hoppers distributed in different water collection tanks, along with subsequent mixing tanks and vertical cylinder structures. This allows the device to collect water samples at different locations and mix them before channeling them through an outlet pipe into the sampling tube for testing. This enables timely detection of water quality deterioration at specific points within the reaction sedimentation tank, thereby improving the representativeness and comprehensiveness of water quality test results and reducing adverse impacts on the stable operation of subsequent systems.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 4 As shown, this embodiment is applicable to the sampling device of the reaction sedimentation tank, including a sampling hopper 5, which is welded to the drain of the water collection tank 2. A baffle plate 4 is fixedly connected at the junction of the sampling hopper 5 and the top of the water collection tank 2. An inclined tube 6 passes through the bottom of the sampling hopper 5. A mixing tank 7 is fixedly connected to the bottom of the inclined tube 6. A vertical cylinder 8 passes through the middle of the bottom of the mixing tank 7. An outlet pipe 9 passes through the bottom of the vertical cylinder 8. A solenoid valve 11 is fixedly installed at the end of the outlet pipe 9. A liquid level sensor 18 is installed at the top of the outlet pipe 9. A sampling tube 12 passes through the bottom of the outlet pipe 9. A needle valve 13 is installed in the middle of the sampling tube 12.

[0024] Specifically, there are multiple sampling hoppers 5, each distributed within a different water collection tank 2. The sampling hoppers 5 are directly connected to the water collection tank 2 and not to the sedimentation tank 1. The sampling port at the top of each sampling hopper 5 is connected to the drain outlet of the water collection tank 2, allowing water from the water collection tank 2 to flow into the sampling hopper 5 through the sampling port. The baffle plate 4 intercepts the water flowing towards the top of the sampling hopper 5, facilitating the flow of water from the water collection tank 2 into the sampling hopper 5. The inclined tube 6 allows the water sample collected in the sampling hopper 5 to flow smoothly into the mixing tank 7 for mixing. The vertical cylinder 8 concentrates the water flow out of the mixing tank 7, ensuring the water in the vertical cylinder 8 flows into the outlet pipe 9. The system generates eddies, which in turn drive the turbine blades 17 inside the vertical cylinder 8 to rotate. This causes the turbine blades 17 to drive the vertical rod 15 and the stirring blades 14 to stir within the mixing tank 7. This facilitates the mixing of the sample water in the mixing tank 7 before it flows to the outlet pipe 9, making the sample water more representative. The solenoid valve 11 is used to cut off the flow of sample water in the outlet pipe 9. When there is too little sample water in the outlet pipe 9, the solenoid valve 11 can be closed, allowing all the sample water to flow into the sampling pipe 12 at the bottom of the outlet pipe 9. This ensures that there is sufficient water sample in the sampling pipe 12, so that the monitoring equipment connected to the sampling pipe 12 can continuously monitor the water source in the sampling pipe 12, thereby ensuring the stability and timeliness of water sample monitoring.

[0025] Furthermore, a protective net cover 3 is provided on one side of the baffle plate 4. The protective net cover 3 is connected to the sampling hopper 5 through the baffle plate 4. The protective net cover 3 is a detachable structure, which can prevent large debris from falling into the sampling hopper 5 and causing blockage of the pipes inside the device. This ensures that the sample water taken in the sampling hopper 5 can smoothly enter the mixing tank 7, and at the same time ensures that the sample water can be smoothly transported from the outlet pipe 9 to the sampling pipe 12.

[0026] Furthermore, the water collection tank 2, the sampling hopper 5, and the mixing tank 7 are all located inside the sedimentation tank 1. A pre-embedded sleeve 10 is inserted through one side wall of the bottom of the sedimentation tank 1. The outlet pipe 9 is connected to the sedimentation tank 1 through the pre-embedded sleeve 10. The function of the pre-embedded sleeve 10 is to allow the outlet pipe 9 to be smoothly led out from one side of the sedimentation tank 1, thereby facilitating the connection between the outlet pipe 9 and the sampling pipe 12.

[0027] Furthermore, a bracket 16 is fixedly connected to the inner wall of the vertical cylinder 8, and a vertical rod 15 is rotatably connected to the middle of the bracket 16. The function of the bracket 16 is to support the vertical rod 15 so that the vertical rod 15 can be kept in a vertical state, thereby facilitating the vertical rod 15 to be driven by the turbine blade 17 to rotate in the vertical direction.

[0028] Furthermore, an agitator 14 is fixedly connected to the top of the vertical rod 15, and a turbine 17 is fixedly connected to the bottom of the vertical rod 15. The turbine 17 is located inside the vertical cylinder 8. The agitator 14 is used to agitate the sample water entering the mixing tank 7, thereby facilitating more uniform mixing of the sample water entering the mixing tank 7 from different sampling hoppers 5, which is more conducive to subsequent water sample testing.

[0029] Furthermore, the solenoid valve 11 is electrically connected to the liquid level sensor 18. The liquid level sensor 18 can monitor the water level in the outlet pipe 9. If the water level in the outlet pipe 9 is low, the solenoid valve 11 can be closed by the liquid level sensor 18, so that all the water in the outlet pipe 9 flows into the sampling pipe 12, thereby ensuring that the sampling pipe 12 is full of water.

[0030] Furthermore, the sampling hopper 5 is connected to the interior of the water collection tank 2, and the sampling hopper 5 is connected to the interior of the mixing tank 7 through the inclined tube 6. The sampling tube 12 is connected to the interior of the mixing tank 7 through the outlet tube 9, so that the collected water samples can be combined into a larger volume, and the water samples from different sampling points can be mixed, thereby improving the comprehensiveness, timeliness and accuracy of water sample collection.

[0031] The method of use in this embodiment is as follows: When using the sampling device applicable to the reaction sedimentation tank 1, the sampling hopper 5 can be welded to the water collection tank 2 first, so that the baffle plate 4 is fixed to the water collection tank 2. At the same time, the protective net cover 3 is installed at the opening at the top of the sampling hopper 5, so that the protective net cover 3 is connected to the baffle plate 4. Then, the outlet pipe 9 is led out from one side of the bottom of the reaction tank through the pre-embedded sleeve 10, and the sampling pipe 12 is connected to the bottom of the outlet pipe 9, so that the pipe opening of the sampling pipe 12 is located between the pre-embedded sleeve 10 and the solenoid valve 11. When water flows into the water collection tank 2, the water flow will be intercepted by the baffle plate 4 and pass through the protective net cover 3 into the sampling hopper 5. Then it flows into the inclined pipe 6 at the bottom of the sampling hopper 5, and then into the mixing tank 7 through the inclined pipe 6. Then it flows into the vertical cylinder 8. When the water flows from the vertical cylinder 8 into the outlet pipe 9, the water in the vertical cylinder 8... Due to the convergence of water flow, a vortex is generated, which drives the turbine blade 17 inside the vertical cylinder 8 to rotate. The turbine blade 17 drives the vertical rod 15 to rotate on the support 16, which in turn drives the agitator blade 14 at the top of the vertical rod 15 to rotate in the mixing tank 7. This agitates the sample water flowing into the mixing tank 7, allowing the sample water from different sampling hoppers 5 to mix in the mixing tank 7. The mixed sample water then flows into the outlet pipe 9 and then into the sampling pipe 12. When the liquid level sensor 18 at the top of the outlet pipe 9 detects that the liquid level in the outlet pipe 9 is low, it sends a signal to the controller, causing the controller to close the solenoid valve 11 at the end of the outlet pipe 9. This allows all the sample water in the outlet pipe 9 to flow into the sampling pipe 12, ensuring that the sampling pipe 12 is full. Finally, the sample water in the sampling pipe 12 flows to the water sample monitoring equipment through the needle valve 13.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
