Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a device for settling turbid samples for water pollution testing. Background Technology

[0002] In water pollution testing, turbid samples usually contain a large number of suspended particles. These particles can interfere with subsequent steps such as optical detection and chromatographic analysis, leading to data deviation. Therefore, it is necessary to allow the suspended particles to settle naturally and separate the supernatant for testing. Some water samples have a high concentration of suspended particles. If the settling time is too long, it will prolong the testing cycle and affect the efficiency of emergency monitoring or batch sample processing.

[0003] Because existing turbid sample settling devices for water pollution detection mostly adopt a vertical settling mode, suspended particles need to overcome liquid resistance to settle vertically. The path is fixed and the distance is long. Especially for light particles or low-concentration suspensions, the settling speed is slow, often requiring several hours or even overnight settling, which is difficult to meet the needs of rapid detection. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing technologies often employ vertical settling methods in traditional settling devices, where suspended particles need to overcome liquid resistance to settle vertically. The path is fixed and the distance is long, especially for light particles or low-concentration suspensions, where the settling speed is slow and often requires several hours or even overnight settling, making it difficult to meet the needs of rapid detection. Therefore, this invention proposes a settling device for turbid samples in water pollution detection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a turbid sample settling device for water pollution detection, comprising a base plate, an mounting plate fixedly connected to the surface of the base plate, a rectangular groove formed on the surface of the mounting plate, a placement box fixedly connected to the side of the base plate near the mounting plate, and adjustment devices provided on both sides of the surface of the base plate. Each adjustment device includes a mounting block, which is fixedly connected to the top of the base plate. The two mounting blocks are rotatably connected to the same movable shaft. A movable placement block is fixedly connected to the surface of the movable shaft. An installation groove is formed on the surface of the movable placement block. A spring is fixedly connected to both sides inside the installation groove. A limit block is fixedly connected to one side of the spring, and a positioning block is fixedly connected to the surface of the limit block.

[0006] Furthermore, a gear is fixedly connected to one side of the movable shaft, and rotating shafts are movably connected to both sides of the surface of the base plate. Two movable placement blocks are provided, both of which are disposed on the surface of the movable shaft.

[0007] Furthermore, a locking rod is rotatably connected to the surface of the rotating shaft, and the side of the locking rod away from the rotating shaft is engaged with the inside of the gear.

[0008] Furthermore, a limiting buffer device is provided on the surface of the rectangular groove. The limiting buffer device includes a bidirectional threaded rod, which is disposed inside the rectangular groove. A rotating block is fixedly connected to one side of the bidirectional threaded rod.

[0009] Furthermore, a sliding block is threadedly connected to the surface of the bidirectional threaded rod, a clamping plate is fixedly connected to the surface of the sliding block, and a support rod is fixedly connected to the bottom of the clamping plate on the side away from the sliding block.

[0010] Furthermore, a sliding groove is provided on the side of the base plate away from the mounting plate, and the bottom of the support rod is slidably connected to the inside of the sliding groove. Limiting rods are fixedly connected to both sides of the inside of the placement box, and several limiting rods are symmetrically distributed inside the placement box.

[0011] Furthermore, a second spring is sleeved on the surface of the limiting rod, a clamping block is fixedly connected to one side of the limiting rod, and movable grooves are opened on both sides of the inner wall of the placement box, with the two sides of the clamping block movably connected to the inside of the movable grooves.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting an adjustment device, the test tubes of the static sample can first be placed inside the movable placement block. At this time, the test tubes of different specifications can be clamped and limited by the action of spring and limiting block. Then, the movable placement block is driven by the action of movable shaft and gear to adjust the angle. When the appropriate static angle is adjusted, the locking rod can be rotated by the rotating shaft and locked onto the surface of the gear. When the static tube is tilted, the sedimentation path of the suspended particles forms an oblique angle with the inner wall of the container. Some particles can slide along the tube wall, reducing the suspension time. At the same time, the actual distance of the particles from the liquid surface to the bottom of the container is shortened in the tilted state, which can promote the particles to gather to the bottom more quickly. Especially for particles with high density or easy agglomeration, it can effectively accelerate the sedimentation process without long waiting time, thereby increasing the working efficiency of the device.

[0014] 2. In this utility model, by setting a limiting buffer device, the test tubes of the static samples can be placed inside the placement box. At the same time, the clamping block can be driven by the second spring and the limiting rod to clamp and limit the test tubes. The clamping block can slide on the surface of the movable groove to clamp and limit different sample test tubes. Then, the rotating block drives the bidirectional threaded rod to rotate. During the operation, it will drive the two sliding blocks to move in both directions, so that the clamping plate limits and stabilizes the upper end of the test tube, avoiding shaking during static placement. The limiting buffer device can flexibly fix the test tube from both sides, which can not only limit the lateral displacement of the test tube to prevent tipping or collision, but also absorb the external vibration energy through the buffer structure to reduce the impact on the liquid inside the test tube, ensure that suspended particles settle in a stable environment, avoid the re-suspension of precipitated particles due to disturbance, and ensure the consistency of static placement effect.

[0022] Please see Figure 1-5This utility model provides a technical solution: a turbid sample settling device for water pollution detection, including a base plate 1, an mounting plate 2 fixedly connected to the surface of the base plate 1, a rectangular groove 3 opened on the surface of the mounting plate 2, a placement box 4 fixedly connected to the side of the surface of the base plate 1 near the mounting plate 2, and adjustment devices 5 provided on both sides of the surface of the base plate 1.

[0023] The specific settings and functions of the adjustment device 5 and the limit buffer device 6 will be explained in detail below.

[0024] In this embodiment: the adjusting device 5 includes a mounting block 51, which is fixedly connected to the top of the base plate 1. The two mounting blocks 51 are rotatably connected to the same movable shaft 52. A movable placement block 53 is fixedly connected to the surface of the movable shaft 52. A mounting groove 55 is opened on the surface of the movable placement block 53. Springs 56 are fixedly connected to both sides inside the mounting groove 55. A limit block 57 is fixedly connected to one side of the springs 56. A positioning block 58 is fixedly connected to the surface of the limit block 57.

[0025] Specifically, a gear 54 is fixedly connected to one side of the movable shaft 52, and rotating shafts 510 are movably connected to both sides of the surface of the base plate 1.

[0026] Specifically, a locking rod 59 is rotatably connected to the surface of the rotating shaft 510, and the side of the locking rod 59 away from the rotating shaft 510 is engaged with the inside of the gear 54.

[0027] The effects achieved by the above components are as follows: by setting the adjustment device 5, the test tubes of different specifications can be clamped and limited by the action of the spring 56 and the limiting block 57. The movable placement block 53 is driven by the action of the movable shaft 52 and the gear 54 to adjust the angle. When the appropriate static angle is adjusted, the locking rod 59 can be rotated by the rotating shaft 510, and the locking rod 59 is locked onto the surface of the gear 54. When the static tube is tilted, the sedimentation path of the suspended particles forms an oblique angle with the inner wall of the container, and some particles can slide along the tube wall, reducing the suspension time and thus increasing the static efficiency of the device.

[0028] Specifically, a limiting buffer device 6 is provided on the surface of the rectangular groove 3. The limiting buffer device 6 includes a bidirectional threaded rod 61, which is located inside the rectangular groove 3. A rotating block 62 is fixedly connected to one side of the bidirectional threaded rod 61.

[0029] Specifically, a sliding block 63 is threadedly connected to the surface of the bidirectional threaded rod 61, a clamping plate 64 is fixedly connected to the surface of the sliding block 63, and a support rod 65 is fixedly connected to the bottom of the side of the clamping plate 64 away from the sliding block 63.

[0030] Specifically, a sliding groove 66 is provided on the side of the base plate 1 away from the mounting plate 2, the bottom of the support rod 65 is slidably connected to the inside of the sliding groove 66, and limit rods 67 are fixedly connected to both sides of the inside of the placement box 4.

[0031] Specifically, a spring 68 is sleeved on the surface of the limiting rod 67, and a clamping block 69 is fixedly connected to one side of the limiting rod 67. Movable grooves 610 are opened on both sides of the inner wall of the placement box 4, and the two sides of the clamping block 69 are movably connected to the inside of the movable grooves 610.

[0032] The effect achieved by the above components is as follows: by setting the limiting buffer device 6, the test tube of the static sample can be placed inside the placement box 4. At the same time, the clamping block 69 can be driven by the spring 68 and the limiting rod 67 to clamp and limit the test tube. This setting can clamp and limit test tubes of different specifications, increasing the application range of the device.

[0033] Working principle:

[0034] By setting the adjustment device 5, the test tubes of the static sample can first be placed inside the movable placement block 53. At this time, the test tubes of different sizes can be clamped and limited by the action of the spring 56 and the limiting block 57. The movable placement block 53 can be adjusted by using the action of the movable shaft 52 and the gear 54. When the appropriate static angle is adjusted, the locking rod 59 can be rotated by the rotating shaft 510, and the locking rod 59 is engaged with the surface of the gear 54. When the static tube is tilted, the sedimentation path of the suspended particles forms an oblique angle with the inner wall of the container. Some particles can slide along the tube wall, reducing the suspension time. At the same time, the actual distance of the particles from the liquid surface to the bottom of the container is shortened in the tilted state, which can promote the particles to gather to the bottom more quickly. Especially for particles with high density or easy agglomeration, it can effectively accelerate the sedimentation process without long waiting time, thereby increasing the working efficiency of the device.

[0035] Then, by setting the limiting buffer device 6, the test tube of the static sample can be placed inside the placement box 4. At the same time, the clamping block 69 can be driven by the spring 68 and the limiting rod 67 to clamp and limit the test tube. The clamping block 69 can slide on the surface of the movable groove 610 to clamp and limit different sample test tubes. Then, the rotating block 62 drives the bidirectional threaded rod 61 to rotate. During the operation, it will drive the two sliding blocks 63 to move in both directions, so that the clamping plate 64 limits and stabilizes the upper end of the test tube, avoiding shaking during static placement. The limiting buffer device 6 can flexibly fix the test tube from both sides, which can not only limit the lateral displacement of the test tube to prevent tipping or collision, but also absorb the external vibration energy through the buffer structure to reduce the impact on the liquid inside the test tube, ensure that suspended particles settle in a stable environment, avoid the re-suspension of precipitated particles due to disturbance, and ensure the consistency of static placement effect.
