Water body collecting and sampling equipment for detecting wastewater of a steel mill

Abstract

This invention relates to the field of water sampling equipment technology, specifically disclosing a water body sampling device for testing wastewater in a steel plant. The device includes a sampling tube with a gripping ring fixedly connected to its top outer surface. When the drive rod rotates, it synchronously drives the mating disc at its bottom to rotate, causing the misaligned groove on the mating disc to intermittently connect with the water delivery tank on the chassis. The drive disc is constantly in an upward-moving state, thus intermittently increasing the negative pressure inside the sampling tube when extracting wastewater. This further enhances the negative pressure, allowing wastewater to enter the sampling tube faster when the water delivery tank is opened, significantly reducing the risk of blockage in the water delivery tank on the chassis. The enhanced negative pressure also absorbs common clumps of impurities accumulated at the bottom of the water delivery tank, improving the accuracy of subsequent testing and preventing a large amount of impurities from being filtered out and affecting the test data.

Description

Technical Field

[0001] This invention relates to the field of water sampling equipment technology, specifically a sampling device for water bodies used in steel plant wastewater testing. Background Technology

[0002] In the field of environmental monitoring and water quality analysis, the detection of wastewater from steel plants is a crucial step in evaluating the effectiveness of industrial wastewater treatment and ensuring ecological and environmental safety. Wastewater sample collection is the first step in the testing process. Given the complex composition and high impurity content of steel plant wastewater, specialized water sampling equipment must possess characteristics such as high-efficiency collection, anti-clogging, strong sample representativeness, and good sealing performance to ensure the accuracy and reliability of subsequent testing data. The performance of such equipment directly affects the judgment of pollutant content and water quality indicators in wastewater, and is a key tool for achieving compliant discharge regulations for steel plant wastewater.

[0003] Existing sampling equipment for steel plant wastewater collection has several shortcomings. Regarding collection efficiency and clogging prevention, traditional equipment often suffers from clogging of sampling channels due to the high impurity content and poor flowability of the wastewater. Furthermore, insufficient negative pressure stability makes rapid and continuous sample collection difficult, and some equipment even filters out a large amount of suspended impurities, affecting sample representativeness. In terms of sealing performance, traditional equipment often uses simple sealing structures such as rubber rings, which are prone to wear and tear after prolonged use, leading to seal failure and a high risk of wastewater leakage. Automatic sealing after sampling is also difficult, hindering sample transport and preservation. In addition, the sealing components of traditional equipment have short lifespans, requiring frequent replacement and resulting in high maintenance costs. Moreover, the coordination between negative pressure regulation and impurity handling is poor, failing to adapt to the complex and variable characteristics of steel plant wastewater and limiting the accuracy and efficiency of wastewater testing.

[0013] According to one embodiment of the present invention, the reinforcing mechanism includes a second magnet ring, which is threadedly connected to the outer surface of the drive rod and rotatably connected through the middle of the drive disk.

[0014] According to one embodiment of the present invention, a filling groove is formed on the side surface of the drive disk, and a first sealing sheet is slidably connected to the bottom surface of the filling groove. Six first sealing sheets are fixedly spaced around the central axis of the drive disk. The outer side of the first sealing sheet is attached to the inner surface of the sampling tube. A first plug rod is symmetrically slidably connected to both sides of the first sealing sheet. A first brake rod is fixedly connected to the inner surface of the first sealing sheet.

The second extrusion block is conical, and the inner end of the second brake rod is arc-shaped. The second extrusion block is staggered from the first extrusion block. When it is necessary to sample sewage, the entire device can be moved to the sampling location by holding the ring. Then, the bottom of the device is submerged in the sewage and the motor is started. As the motor starts, it will drive the drive rod to rotate, which will drive the drive disc to slide from the bottom of the sampling tube upward through the thread on the drive rod, so that the bottom of the sampling tube is in a negative pressure state, thereby drawing sewage into the sampling tube through the water supply tank on the chassis.

[0016] (III) Beneficial Effects

[0017] This invention provides a sampling device for collecting wastewater samples from steel mills. It has the following beneficial effects:

[0018] (I) The wastewater sampling equipment for this steel plant uses a drive rod that rotates synchronously with the mating disc at its bottom. This causes the misaligned groove on the mating disc to intermittently connect with the water delivery trough on the chassis. The drive disc is always in an upward position, which intermittently increases the negative pressure in the sampling tube when the wastewater is being drawn. This further increases the negative pressure when the water delivery trough is opened, allowing the wastewater to enter the sampling tube faster. This significantly reduces the problem of blockage in the water delivery trough on the chassis. The further increased negative pressure also helps to absorb ordinary clumps of impurities accumulated at the bottom of the water delivery trough, thereby improving the accuracy of subsequent testing and preventing a large number of impurities from being filtered out and affecting the test data.

[0019] (II) The wastewater sampling equipment used in this steel plant automatically seals the water delivery tank after a sufficient amount of wastewater has been collected in the sampling tube. This avoids the problem of not being able to observe whether the water delivery tank is sealed when the chassis is submerged in wastewater. When the drive rod continues to rotate, it drives the No. 1 magnetic ring at the bottom to rotate. At this time, the mating disc can no longer rotate. That is, the No. 1 magnetic ring begins to rotate relative to the mating disc under the action of rotational force. This achieves protection for the mating disc after it is fixed, avoiding the problem of the drive rod continuously rotating and damaging the mating disc after it is fixed. This greatly improves the working stability of this equipment. When the air pressure enters the air pressure tank, it will... When the sample enters the sealing groove, under the action of air pressure, it begins to push the sealing ring inside the sealing groove upward, eventually firmly adhering to the bottom surface of the mating plate. This achieves automatic and synchronous sealing of the water tank after the mating plate is fixed, greatly improving the overall sealing performance of the equipment and preventing sewage from leaking through the gaps at the bottom of the sampling tube. The sealing rings are connected by a connecting rod, which is limited by a limiting rod, so that all four sealing rings move upward synchronously when they move upward. This greatly improves the working stability of the equipment and avoids the problem of some sealing rings being unable to move upward and seal due to their service life.

[0020] (III) The wastewater sampling equipment used in this steel plant initially rotates synchronously with the second magnetic ring when the drive rod rotates. This causes the second magnetic ring to rotate a certain distance relative to the drive disc, resulting in the first and second extrusion blocks on its outer surface rotating synchronously. This gradually brings the first and second brake rods into contact and extrusion, causing them to move outwards from the drive disc. This presses the outer surfaces of the first and second sealing plates against the inner surface of the sampling tube. The misaligned first and second sealing plates seal the side surface of the drive disc, ensuring a tight seal when the drive disc moves upwards. This helps maintain a negative pressure in the sampling tube during wastewater sampling. Unlike traditional methods using rubber rings for sealing, the first and second sealing plates remain pressed against the inner wall of the sampling tube as the drive disc moves upwards. This provides a more stable seal and significantly extends the equipment's service life, avoiding the problems associated with conventional rubber rings. The problem of frequent ring replacement is addressed by the following mechanism: When the drive disc moves downwards, it first causes the second magnetic ring to reverse, thus losing its squeezing force on the first and second brake levers. Under the action of elastic force, the first and second brake levers begin to retract and reset. The first and second squeezing blocks eventually contact the first and second stop blocks, preventing them from rotating relative to the drive disc. This causes the drive disc to move downwards, allowing the first and second sealing plates to detach from the inner wall of the sampling tube during wastewater extraction. A simple surface contact between the drive disc and the inner wall of the sampling tube provides a relative seal, maintaining an absolute seal at the top of the sampling tube during wastewater extraction. A secondary seal is provided by the sliding ring after wastewater extraction, significantly improving the sealing performance of the device. Furthermore, the use of the first and second sealing plates is automatically reduced during wastewater discharge, greatly extending their service life and preventing permanent deformation caused by prolonged compression.

The second sealing plate 49 is offset from the first sealing plate 43. The outer side of the second sealing plate 49 is attached to the inner surface of the sampling tube 1. A second insertion rod 410 is symmetrically slidably connected to both sides of the second sealing plate 49. A second brake rod 411 is fixedly connected to the inner surface of the second sealing plate 49. The second brake rod 411 is elastically slidably connected to the drive disk 36.

The inner end of the second brake lever 411 is set in an arc shape. The second extrusion block 413 and the first extrusion block 48 are staggered.

[0043] During operation, when wastewater sampling is required, the entire device can be moved to the sampling location using the grip ring 2. Then, the bottom of the device is submerged in the wastewater, and the motor 32 is started. The motor 32 drives the drive rod to rotate, causing the drive disc 36 to slide upwards from the bottom of the sampling tube 1 via the threads on the drive rod. This creates a negative pressure at the bottom of the sampling tube 1, allowing wastewater to be drawn into the sampling tube 1 through the water inlet 35 on the chassis 34. The rotation of the drive rod simultaneously rotates the mating disc 38 at its bottom, causing the misalignment groove 39 on the mating disc 38 to intermittently connect with the water inlet 35 on the chassis 34. Meanwhile, the drive disc 36 is constantly moving upwards, thus intermittently increasing the negative pressure within the sampling tube 1 during wastewater extraction. When the water delivery tank 35 is opened during wastewater extraction, the enhanced negative pressure allows the wastewater to enter the sampling tube 1 faster, significantly reducing the risk of blockage in the water delivery tank 35 on the chassis 34. The enhanced negative pressure also helps to absorb common clumps of impurities accumulated at the bottom of the water delivery tank 35, improving the accuracy of subsequent testing and preventing a large amount of impurities from affecting the test data. When the drive disc 36 moves to the top of the sampling tube 1, the misalignment groove 39 on the mating disc 38 misaligns with the water delivery tank 35 on the chassis 34, thus sealing the water delivery tank 35 on the chassis 34. This facilitates the sealed transfer of the wastewater. As the drive disc 36 moves upwards to the top inside the sampling tube 1, it gradually contacts and compresses the bottom of the sliding ring 313, causing the sliding ring to... Synchronously with the drive disc 36, 313 moves upward to compress the compression chamber 312, delivering its internal air pressure to the air-gathering groove 315. The air pressure then enters the air pressure groove 316 on the chassis 34 via the air-gathering groove 315, and finally enters the fitting cover 317 through the connecting hole at the bottom of the fitting cover 317. This pushes the insertion block 318 to move outward from the fitting cover 317. As the mating disc 38 continues to rotate, the insertion groove 320 on the mating disc 38 aligns with the insertion block 318, limiting the mating disc 38. At this point, the misalignment groove 39 on the mating disc 38 misaligns with the water delivery groove 35 on the chassis 34. This automatically closes the water delivery groove 35 after the sampling tube 1 has collected sufficient wastewater, preventing the chassis 34 from being submerged in wastewater and thus ensuring the water delivery groove 35 is visible. Regarding the issue of whether it is sealed, when the drive rod continues to rotate, it drives the first magnetic ring 310 at the bottom to rotate. At this time, the mating disc 38 can no longer rotate. That is, under the action of rotational force, the first magnetic ring 310 begins to rotate relative to the mating disc 38. This achieves protection for the mating disc 38 after it is fixed, avoiding the problem of the drive rod continuing to rotate and damaging the mating disc 38 after it is fixed. This greatly improves the working stability of this equipment. When air pressure enters the air pressure groove 316, it will simultaneously enter the sealing groove 321. Under the action of air pressure, it begins to push the sealing ring 322 in the sealing groove 321 upward, and finally firmly adheres to the bottom surface of the mating disc 38. Thus, after the mating disc 38 is fixed, it automatically and synchronously seals the area around the water supply tank 35.This significantly improves the overall sealing performance of the equipment, preventing sewage from leaking through the gaps at the bottom of the sampling pipe 1. The sealing rings 322 are connected via connecting rods 323, which are then limited by limiting rods 324. This ensures that all four sealing rings 322 move upwards synchronously, greatly improving the equipment's operational stability and preventing the problem of some sealing rings 322 failing to move upwards and achieve sealing due to their age. When the drive rod rotates, it initially drives the second magnetic ring 41 to rotate synchronously, causing the second magnetic ring 41 to rotate a certain distance relative to the drive disc 36, thus controlling the first extrusion block 48 and the second extrusion block 48 on its outer surface. The extrusion block 413 begins to rotate synchronously, gradually contacting and extruding brake levers 45 and 411. This causes brake levers 45 and 411 to move outward from the drive disc 36, thus pressing the outer surfaces of sealing plates 43 and 49 against the inner surface of the sampling tube 1. The misaligned sealing plates 43 and 49 seal the side surface of the drive disc 36, ensuring a tight seal as the drive disc 36 moves upward. This helps maintain a negative pressure in the sampling tube 1 during wastewater sampling, unlike the traditional method of using rubber rings for sealing. 49. When the drive disc 36 moves upward, it is always pressed against the inner wall of the sampling tube 1, which not only provides a more stable seal but also significantly extends the service life of the device, avoiding the problem of frequent replacement of conventional rubber rings. Simultaneously, when the drive disc 36 moves downward, it first causes the second magnet ring 41 to reverse, thus losing the pressing force on the first brake lever 45 and the second brake lever 411. Under the action of elastic force, the first brake lever 45 and the second brake lever 411 begin to retract and reset, and the first pressing block 48 and the second pressing block 413 eventually contact the first stop block 47 and the second stop block 412, preventing them from continuing to rotate relative to the drive disc 36. This causes the drive disc 36 to begin moving downward, thus achieving… When the wastewater is removed, the first sealing plate 43 and the second sealing plate 49 begin to disengage from the inner wall of the sampling tube 1. A simple surface contact between the drive disc 36 and the inner wall of the sampling tube 1 provides a relative seal, ensuring an absolute seal at the top of the sampling tube 1 during wastewater extraction. A secondary seal is provided by the sliding ring 313 after wastewater extraction, significantly improving the sealing performance of the device. Furthermore, the use of the first sealing plate 43 and the second sealing plate 49 is automatically reduced during wastewater discharge, greatly extending their service life and preventing permanent deformation caused by prolonged compression of the first sealing plate 43 and the second sealing plate 49.
