Description

Technical Field

[0001] This utility model relates to the field of wastewater sampling technology, and more specifically, to a wastewater sampling storage device. Background Technology

[0002] With the rapid development of industrialization and urbanization, environmental pollution has become increasingly serious. Wastewater discharge has become one of the important sources of environmental pollution. In order to understand and assess the degree and impact of environmental pollution, environmental monitoring is necessary. Wastewater sampling is an important part of environmental monitoring. By collecting wastewater samples and conducting analysis and testing, key information such as the composition of wastewater and the concentration of pollutants can be obtained, providing a scientific basis for environmental management, water resource protection and pollution control.

[0003] When existing wastewater sampling storage devices are used for sampling, the device is placed into the wastewater for sampling. Due to the large amount of dirt in the wastewater, the dirt will enter the inner cavity of the storage device along with the wastewater through the pipes. With the increase of sampling times, impurities gradually accumulate on the inner wall of the pipes, which not only affects the smoothness of water flow and reduces sampling efficiency, but also re-mixes into the water sample when the water flows through in subsequent streams, causing secondary pollution and seriously reducing the purity of the water sample. This, in turn, affects the filtration effect of the entire sampling device. In addition, it is difficult to accurately control the amount of water sample according to the precise requirements of different test items during sampling. Often, too much water sample is collected, resulting in waste of resources, or too little water sample is collected, which cannot meet the requirements of all test items. This has brought great obstacles to the smooth progress of wastewater testing. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater sampling storage device to solve the problem of difficulty in efficiently and accurately sampling wastewater.

[0005] To achieve the above objectives, this utility model provides a wastewater sampling storage device, including a storage box. A partition is fixedly connected inside the storage box. Two symmetrical filter frames are arranged near the top of the storage box, each containing a filter screen. The inner and outer walls of the two filter frames are flush with the inner and outer walls of the storage box, respectively. A fixed tube is fixedly connected to the center of the partition. A cleaning device is installed inside the fixed tube to clean the inner wall of the fixed tube. The cleaning device includes a support rod fixedly connected to the top wall of the storage box. Multiple movable blocks are slidably connected to the support rod. Connecting rods are fixedly connected to the outer walls of the multiple movable blocks in an array. A scraper is fixedly connected to the end of the multiple connecting rods away from the movable blocks, and the outer wall of the scraper is in contact with the inside of the fixed tube. A moving device is provided on the inner wall of the storage box to seal the filter frames.

[0006] As water flows out of the fixed pipe, the impact force of the water flow drives the scraper to clean impurities from the inner wall of the fixed pipe, further improving the purity of the water sample and enhancing the overall filtration effect.

[0007] As a further improvement to this technical solution, the moving device includes a sleeve fixedly connected to the lower end of the lowermost movable block, and the sleeve is fitted over the outside of the support rod. Cylindrical rods are symmetrically fixedly connected to the outer wall of the sleeve. Vertical rods are fixedly connected to the top of the ends of the two cylindrical rods away from the sleeve. The upper end of the vertical rod passes through the partition and is fixedly connected to a blocking plate. The outer wall of the blocking plate fits against the inner wall of the filter frame, and the diameter of the blocking plate is larger than the diameter of the filter frame.

[0008] During cleaning, the blockage plate moves, stopping the water from entering the storage tank and precisely controlling the water volume inside, providing comprehensive and powerful support for the smooth progress of wastewater testing.

[0009] As a further improvement to this technical solution, a sleeve is fixedly connected to the inner top wall of the storage box, the lower end of the sleeve does not contact the upper end of the partition, and the sleeve is fitted over the outside of the fixed tube.

[0010] As a further improvement to this technical solution, two sets of symmetrically arranged sliding grooves are provided in the middle position of the filter frame. Electromagnetic blocks are slidably connected inside the two sets of sliding grooves. The electromagnetic blocks closer to the inside are fixedly connected to the outer wall of the blocking plate, and the electromagnetic blocks closer to the outside are fixedly connected to a cleaning plate. The inner wall of the cleaning plate is in contact with the outer wall of the filter frame.

[0011] As a further improvement to this technical solution, a fixed block is fixedly connected to one end of each of the two cylindrical rods near the inner wall of the storage box. A movable block is slidably connected inside the fixed block. One end of the movable block passes through one side of the fixed block and fits against the inner wall of the storage box. A push rod is fixedly connected to the outer wall of the movable block. The push rod passes through the fixed block, and a groove adapted to the push rod is provided on the fixed block. Two limiting grooves adapted to the movable block are provided on the inner wall of the storage box.

[0012] As a further improvement to this technical solution, a setback spring is fixedly connected between adjacent movable blocks, and the setback spring is sleeved on the support rod.

[0013] As a further improvement to this technical solution, a filter plate is fixedly connected inside the storage box, and the filter plate is located below the partition. The lower side of the filter plate and the inner wall of the storage box form a storage cavity.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: By using the siphon principle to promote water circulation, the water sample in the storage tank is continuously exchanged, effectively preventing water quality changes due to prolonged stagnation. This ensures that the collected water sample truly reflects the current state of the wastewater, making it highly timely and representative. When the water flows out of the fixed pipe, the impact force of the water flow drives a scraper to clean impurities from the inner wall of the fixed pipe, further improving the purity of the water sample and enhancing the overall filtration effect. Furthermore, during cleaning, the blockage plate moves, stopping the water from entering the storage tank, precisely controlling the water volume within the tank. This avoids excessive water waste or insufficient water affecting testing, providing comprehensive and powerful support for the smooth operation of wastewater testing. Attached Figure Description

[0027] Example 1

[0028] Please see Figures 1-3 As shown, this embodiment provides a wastewater sampling storage device, including a storage tank 1. A partition 11 is fixedly connected inside the storage tank 1. Two symmetrical filter frames 14 are arranged near the top of the storage tank 1, each containing a filter screen. The inner and outer walls of the two filter frames 14 are flush with the inner and outer walls of the storage tank 1, respectively. A fixing pipe 12 is fixedly connected to the center of the partition 11. A sleeve 13 is fixedly connected to the inner top wall of the storage tank 1. The lower end of the sleeve 13 does not contact the upper end of the partition 11. The sleeve 13 is fitted over the fixing pipe 12. When using this device, the storage tank 1 is placed in water, and water flows through the partition 12... The filter frame 14 enters the storage tank 1. The filter screen inside the filter frame 14 filters the impurities in the water once. Then, when the water flows into the storage tank 1, it uses the siphon principle. When the water in the storage tank 1 reaches the height of the fixed pipe 12, the water in the storage tank 1 falls due to gravity, which causes the pressure to drop. The atmosphere then forces the liquid at the higher level into the fixed pipe 12, causing the water in the storage tank 1 to flow out from the fixed pipe 12. The continuous water flow allows the water in the storage tank 1 to be constantly exchanged, avoiding water quality changes caused by prolonged stagnation. This ensures that the collected water samples are more timely and representative, and better reflect the true situation of the wastewater.

[0029] Please see Figures 2-4As shown, a cleaning device 2 is installed inside the fixed tube 12. The cleaning device 2 is used to clean the inner wall of the fixed tube 12. The cleaning device 2 includes a support rod 21 fixedly connected to the top wall of the storage tank 1. Multiple movable blocks 22 are slidably connected to the support rod 21. Connecting rods 23 are fixedly connected to the outer wall array of the multiple movable blocks 22. A scraper 24 is fixedly connected to the end of the multiple connecting rods 23 away from the movable blocks 22. The outer wall of the scraper 24 is in contact with the inside of the fixed tube 12. A return spring 25 is fixedly connected between adjacent movable blocks 22. The return spring 25 is sleeved on the support rod 21. When water falls down from the fixed tube 12, the impact force of the water drives the movable blocks 22 to press down the return spring 25. The movable blocks 22 drive the scraper 24 to move down through the connecting rods 23. The scraper 24 moves down to clean the impurities attached to the inner wall of the fixed tube 12, further improving the purity of the water sample and enhancing the filtration effect of the entire sampling device.

[0030] Please see Figure 2 and Figure 5 As shown, a moving device 3 is provided on the inner wall of the storage box 1. The moving device 3 is used to block the filter frame 14. The moving device 3 includes a sleeve 31 fixedly connected to the lower end of the movable block 22 located at the bottom, and the sleeve 31 is sleeved on the outside of the support rod 21. Cylindrical rods 32 are symmetrically fixedly connected to the outer wall of the sleeve 31. Vertical rods 33 are fixedly connected to the top of the ends of the two cylindrical rods 32 away from the sleeve 31. The upper end of the vertical rod 33 passes through the partition 11 and is fixedly connected to a blocking plate 34. The outer wall of the blocking plate 34 fits against the inner wall of the filter frame 14, and the blocking plate 34... The diameter is larger than that of the filter frame 14. When the movable block 22 moves downward, it drives the sleeve 31 to move downward. The movement of the sleeve 31 drives the cylindrical rod 32 and the vertical rod 33 to move downward synchronously. The downward movement of the vertical rod 33 drives the blocking plate 34 to move downward. The downward movement of the blocking plate 34 blocks the filter frame 14, thereby stopping the water from entering the storage tank 1. This achieves control over the water volume inside the storage tank 1, meets the specific requirements of different subsequent testing items for water sample volume, avoids waste due to excessive water sample, or failure to complete all testing items due to insufficient water sample, and ensures the accuracy of water sample volume and the smooth progress of the experiment.

[0031] Please see Figure 2 and Figure 5As shown, two sets of symmetrically arranged sliding grooves 35 are provided in the middle of the filter frame 14. Electromagnetic blocks 36 are slidably connected inside the two sets of sliding grooves 35. The electromagnetic blocks 36 closer to the inside are fixedly connected to the outer wall of the blocking plate 34, and the electromagnetic blocks 36 closer to the outside are fixedly connected to the cleaning plate 37. The inner wall of the cleaning plate 37 is in contact with the outer wall of the filter frame 14. When the cleaning plate 37 moves down, it drives the electromagnetic blocks 36 to move downward inside the sliding grooves 35. Since the two electromagnetic blocks 36 are attracted to each other, the movement of one electromagnetic block 36 will drive the other electromagnetic block 36 to move. The movement of the electromagnetic blocks 36 drives the cleaning plate 37 to move down. The downward movement of the cleaning plate 37 scrapes off the impurities attached to the surface of the filter screen, so as to avoid clogging of the filter screen and affecting the next use.

[0032] Please see Figure 2 and Figure 6 As shown, each of the two cylindrical rods 32 has a fixed block 38 fixedly connected to one end near the inner wall of the storage tank 1. A movable block 381 is slidably connected inside the fixed block 38. One end of the movable block 381 passes through one side of the fixed block 38 and fits against the inner wall of the storage tank 1. A compression spring is fixedly connected between the movable block 381 and the inner wall of the fixed block 38. A push rod 382 is fixedly connected to the outer wall of the movable block 381. The push rod 382 passes through the fixed block 38, and a groove adapted to the push rod 382 is provided on the fixed block 38. Two limiting grooves adapted to the movable block 381 are provided on the inner wall of the storage tank 1. When water falls from the inside of the fixed pipe 12, the cylindrical rod 32 will move back and forth under the reaction force of the return spring 25, thereby causing the blocking plate 34 to move back to its original position. To avoid the inconvenience of sealing the filter frame 14, the position of the cylindrical rod 32 needs to be limited. When the cylindrical rod 32 moves downward, it drives the fixed block 38 to move downward. At this time, the compression spring is squeezed, and the fixed block 38 drives the moving block 381 to move downward. When the moving block 381 moves into the limiting groove, it is driven to move under the reaction force of the compression spring, so that the moving block 381 is engaged with the limiting groove, thereby limiting the position of the cylindrical rod 32 and improving the sealing effect of the blocking plate 34 on the filter frame 14. When the filter frame 14 needs to be opened next time, the moving push rod 382 drives the moving block 381 to reset. Under the reaction force of the reset spring 25, the blocking plate 34 is reset to open the filter frame 14, which can then be used.

[0033] Please see Figure 2 As shown, a filter plate 15 is fixedly connected inside the storage tank 1, and the filter plate 15 is located below the partition 11. The lower side of the filter plate 15 and the inner wall of the storage tank 1 form a storage cavity. Water falling from the fixed pipe 12 undergoes secondary filtration through the filter plate 15, and the water after secondary filtration is stored in the storage cavity.

[0034] In practical use, the wastewater sampling storage device of this embodiment involves placing the storage tank 1 in water. Water then enters the storage tank 1 through the filter frame 14, where the filter screen initially filters impurities in the water, reducing the entry of large particles and some other impurities. As water continues to flow in, the water level in the storage tank 1 rises. When the water level reaches the height of the fixed pipe 12, the siphon principle begins to work. At this time, the water in the storage tank 1 falls due to gravity, and the pressure inside the tank decreases accordingly. Atmospheric pressure forces the higher-level liquid into the fixed pipe 12, causing the water in the storage tank 1 to flow out from the fixed pipe 12. This continuous water flow promotes constant water exchange in the storage tank 1, effectively preventing water quality changes caused by prolonged stasis of the water sample and ensuring that the collected water sample accurately reflects the current state of the wastewater.

[0035] As water flows out of the fixed pipe 12, the impact force of the water flow will cause the movable block 22 to move downward. The movable block 22 squeezes the return spring 25, and at the same time, it drives the scraper 24 to move downward through the connecting rod 23. The scraper 24 can clean the impurities attached to the inner wall of the fixed pipe 12, further improve the purity of the water sample, and enhance the filtration effect of the overall device.

[0036] When the movable block 22 moves down, it will also drive the sleeve 31 to move. The sleeve 31 will then drive the cylindrical rod 32 and the vertical rod 33 to move down simultaneously. Finally, the vertical rod 33 will drive the blocking plate 34 to move down. The blocking plate 34 will block the filter frame 14, thereby stopping the water from entering the storage tank 1. This will accurately control the water volume in the storage tank 1, meet the different requirements of various subsequent testing projects for water sample volume, and avoid waste caused by too much water sample or failure to carry out the testing work due to too little water sample.
