Description

Technical Field

[0001] This utility model relates to the field of sampling technology, specifically to a filter bed sediment sampling device. Background Technology

[0002] Filter beds are key equipment in the water treatment process. They remove suspended solids, colloids, microorganisms and other impurities from the water through filtration. Sampling and analyzing the sediment in the filter bed can help us understand the filtration effect, the amount of impurities retained and the degree of pollution of the filter media, thereby determining whether the filter bed is operating normally. For example, if the sediment contains a large amount of organic matter or microorganisms, it may mean that the biological treatment effect of the filter bed is not good, and the operating parameters of the filter bed need to be adjusted.

[0003] The quality of the effluent from the filter bed is directly related to the safety and reliability of the water supply. By sampling and analyzing the sediment in the filter bed, potential problems that may affect the quality of the effluent can be detected in a timely manner, such as the leakage of fine particles caused by damage or aging of the filter media, or the excessive reproduction of microorganisms in the filter bed.

[0004] Settlements at different depths in a filter bed can vary in composition, particle size, and pollutant content. However, most existing filter bed particulate matter samples are taken directly from the filter bed using pumping equipment, which causes particles from different layers to mix together, increasing the time wasted during testing. Utility Model Content

[0005] Given that the sediment at different depths in the aforementioned filter beds may vary in terms of composition, particle size, and pollutant content, and that existing methods for sampling particulate matter in filter beds mostly involve direct extraction using pumping equipment, resulting in the mixing of particles from different layers and increasing the time wasted during testing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a filter bed sediment sampling device, comprising: a cylindrical extraction tube and a mounting cover, wherein the mounting cover is rotatably connected to the upper end of the cylindrical extraction tube, the inner ring of the mounting cover is provided with threads, and the outer arc surface of the cylindrical extraction tube is also provided with a threaded groove, a cylindrical stop block is fixedly connected inside the cylindrical extraction tube, the upper surface of the cylindrical stop block is connected through the mounting cover, a cylindrical tube is provided through the upper surface of the mounting cover, a cylindrical lifting rod is slidably connected to the inner ring of the cylindrical stop block, a mounting block is rotatably connected to the lower end of the cylindrical lifting rod, the outer side of the mounting block is wrapped with a rubber layer, and a nozzle is installed at the lower end of the cylindrical extraction tube.

[0007] In a preferred embodiment of the filter sediment sampling device of this utility model, a pull hook is fixedly connected to the upper surface of the cylindrical lifting rod, a connecting rod is fixedly connected to the arc surface of the cylindrical lifting rod, an anti-slip layer is wrapped on the rod body of the connecting rod, and an arc-shaped mounting block is provided through the rod body of the cylindrical cylinder.

[0008] In a preferred embodiment of the filter sediment sampling device of this utility model, the arc-shaped mounting block and the cylindrical tube are fixedly connected, a round rod is provided through the upper surface of the arc-shaped mounting block, and an extension rod is provided on the round rod.

[0009] In a preferred embodiment of the filter sediment sampling device of this utility model, an arc-shaped notch is provided on the upper surface of the extension rod, an arc-shaped notch is also provided on the lower surface of the extension rod, a circular docking plate is fixedly provided on the vertical surface of the round rod, and a circular docking interface is provided on the vertical surface of the extension rod.

[0010] In a preferred embodiment of the filter sediment sampling device of this utility model, an arc-shaped lifting plate is provided through the lower surface of the extension rod, a lifting groove is provided at the intersection of the arc-shaped lifting plate and the extension rod, a rectangular mounting block is provided on the arc surface of the arc-shaped lifting plate, and a groove is provided at the intersection of the rectangular mounting block and the extension rod.

[0011] As a preferred embodiment of the filter sediment sampling device of this utility model, an arc-shaped interface is provided on the upper surface of the round rod, and a rectangular fixing plate is also provided on the arc surface outside the round rod.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0013] 1. This equipment uses a puncture sampling method, which can ensure to a certain extent that the samples will not be mixed. Layered sampling can obtain sediment samples from different layers, and gain a more detailed understanding of the vertical distribution of sediment in the filter bed. This helps to accurately assess the filtration effect and pollution level of each part of the filter bed.

[0014] 2. The extraction equipment of this device can adapt to filter pools of different depths, and there will be no phenomenon that sampling is impossible due to the filter pool being too deep. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments. Example 1:

[0023] Reference Figure 1-3This first embodiment of the present invention discloses a filter bed sediment sampling device, comprising: a cylindrical extraction tube 1 and a mounting cover 2. The mounting cover 2 is rotatably connected to the upper end of the cylindrical extraction tube 1. The inner ring of the mounting cover 2 is provided with threads, and the outer arc surface of the cylindrical extraction tube 1 is also provided with a threaded groove. A cylindrical stop block 3 is fixedly connected inside the cylindrical extraction tube 1. The upper surface of the cylindrical stop block 3 is connected through the mounting cover 2. A cylindrical cylinder 4 is provided through the upper surface of the mounting cover 2. A cylindrical lifting rod 5 is slidably connected to the inner ring of the cylindrical stop block 3. A mounting block 6 is rotatably connected to the lower end of the cylindrical lifting rod 5. The outer side of the mounting block 6 is wrapped with a rubber layer 7. A nozzle 8 is installed at the lower end of the cylindrical extraction tube 1.

[0024] A pull hook 9 is fixedly connected to the upper surface of the cylindrical lifting rod 5, and a connecting rod 10 is fixedly connected to the arc surface of the cylindrical lifting rod 5. The rod body of the connecting rod 10 is covered with an anti-slip layer 11, and an arc-shaped mounting block 12 is provided through the rod body of the cylindrical tube 4.

[0025] When using it, first determine whether there is a lot or a little sediment. If there is a lot, have a worker point the nozzle 8 downwards and slowly insert it. Meanwhile, another worker holds the anti-slip layer 11 with their hand and continuously raises the cylindrical lifting rod 5 through the anti-slip layer 11 during the insertion process. This is because the mounting block 6 is rotatably connected to the rod body at the lower end of the cylindrical lifting rod 5. The mounting block 6 is wrapped with a rubber layer 7. As the cylindrical lifting rod 5 rises, a negative pressure will be generated inside the cylindrical extraction tube 1, thereby sucking in the sample that comes into contact with it when it is pressed down.

[0026] When the sediment is relatively sparse, the worker pressing the nozzle should also use a gradual descent method, but during the descent, the nozzle should not be squeezed against the sediment. Then, follow the operating steps described above. Example 2:

[0027] Reference Figure 1 , 3 4 is the second embodiment of this utility model. The difference between this embodiment and the first embodiment is that the arc-shaped mounting block 12 and the cylindrical tube 4 are fixedly connected, and a round rod 13 is provided through the upper surface of the arc-shaped mounting block 12, and an extension rod 14 is provided on the round rod 13.

[0028] An arc-shaped notch 15 is provided on the upper surface of the extension rod 14, and an arc-shaped notch 15 is also provided on the lower surface of the extension rod 14. A circular mating plate 16 is fixedly provided on the vertical surface of the round rod 13, and a circular mating interface 17 is provided on the vertical surface of the extension rod 14.

[0029] An arc-shaped lifting plate 18 is provided through the lower surface of the extension rod 14. A lifting groove is provided at the intersection of the arc-shaped lifting plate 18 and the extension rod 14. A rectangular mounting block 19 is provided on the arc surface of the arc-shaped lifting plate 18. A groove 20 is provided at the intersection of the rectangular mounting block 19 and the extension rod 14.

[0030] An arc-shaped interface 21 is provided on the upper surface of the round rod 13, and a rectangular fixing plate is also provided on the arc surface of the outer side of the round rod 13.

[0031] When the filter is found to be deep, first use your hand to raise the rectangular mounting block 19, which was originally lowered by gravity. Then, do not let go of it. Align the circular interface 17 on the extension rod 14 with the circular docking plate 16. Then insert the circular docking plate 16 into the circular interface 17. Then release your hand that has been supporting the rectangular mounting block 19. As the obstruction disappears, the arc-shaped lifting plate 18 will descend under gravity and eventually fall into the arc-shaped interface 21. Because there is a rectangular fixing plate on the arc surface of the round rod 13, and the upper surface of the rectangular fixing plate has a mounting hole, finally rotate the threaded rod on the upper surface of the rectangular mounting block 19 to temporarily fix the rectangular fixing plate and the rectangular mounting block 19.

[0032] After installation, prepare the rope and fix one end of the lifting rope to the pull hook 9. Then follow the operating steps in Example 1.

[0033] The remaining structure is the same as that in Example 1.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
