[0027] The utility model provides a lake or river bottom sediment filtering device.
[0028] Please refer to Figures 1 to 3 In one embodiment of the utility model, the lake and river bottom sediment filtering device includes a frame 10, a sample storage box 20, a filtering and screening module 30 and a guide tube 40, wherein the filtering and screening module 30 is fixed to the frame 10, the sample storage box 20 is arranged above the filtering and screening module 30, and the filtering and screening module 30 is connected to the sample storage box 20 through the guide tube 40; the filtering and screening module 30 module includes a shell 31, a first conical screen 32, a second conical screen 33 and a driving motor 34, the driving motor 34 is arranged outside the shell 31, and is respectively connected to the axial direction of the first conical screen 32 and the axial direction of the second conical screen 33, the first conical screen 32 is connected to the axial direction of the second conical screen 33, and the first conical screen 32 is connected to the axial direction of the second conical screen 33. The cross-sectional dimensions of the first conical screen 32 and the second conical screen 33 gradually increase from the direction close to the driving motor 34 to the direction away from the driving motor 34. The first conical screen 32 is sleeved in the second conical screen 33. The mesh number of the first conical screen 32 is smaller than the mesh number of the second conical screen 33. The end of the first conical screen 32 facing the driving motor 34 is arranged in the shell 31, and the end of the first conical screen 32 facing away from the driving motor 34 extends out of the shell 31. The end of the guide tube 40 facing away from the sample storage box 20 is arranged in the first conical screen 32, and the second conical screen 33 is arranged in the shell 31.
[0029] Specifically, in the present embodiment, the sample storage box 20 is used to store sediment samples extracted or excavated underwater, and the sediment in the sample storage box 20 is introduced into the first conical screen 32 of the filtering and screening module 30 through the guide pipe 40, and the sediment is subjected to the first filtering and screening treatment by the first conical screen 32; the first conical screen 32 and the second conical screen 33 are similar in structure, the first conical screen 32 is sleeved in the second conical screen 33, and the mesh number of the first conical screen 32 is smaller than the mesh number of the second conical screen 33, so that after the sediment passes through the first screening treatment of the first conical screen 32, the particles with larger diameters remain in the first conical screen 32 and are discharged along the conical surface of the screen under the action of gravity, while the particles with smaller diameters pass through the first conical screen 32 and fall on the inner surface of the second conical screen 33 for the second filtering and screening treatment.
[0030] As can be seen from the above, the cross-sectional size of the first conical screen 32 gradually increases in the direction away from the drive motor 34. Furthermore, the ends of the first conical screen 32 and the second conical screen 33 close to the drive motor 34 are closed ends without sieve holes. The closed ends of the first conical screen 32 and the second conical screen 33 are connected to the drive motor 34, and the open end of the first conical screen 32 partially extends out of the housing 31. The conical screen with this structure allows the larger solid particles in the sediment sample introduced by the guide tube 40 to be filtered out by the conical screen first. At the same time, the separated solid particles can slide out of the screen under the action of gravity along the inclined internal mesh surface of the conical screen to avoid blocking the sieve holes on the screen and affecting the filtering effect. The first conical screen 32 and the second conical screen 33 rotate under the action of the drive motor 34 to avoid the accumulation of solid particles on the surface of the screen.
[0031] As a preferred embodiment, the end of the first conical screen 32 facing the drive motor 34 is a closed end, and the end of the first conical screen 32 away from the drive motor 34 is an open end; and the guide tube 40 extends into the first conical screen 32 and is close to the closed end of the first conical screen 32. The guide tube 40 is extended into the closed end close to the first conical screen 32, so as to fully utilize the filtering area of the first conical screen 32 and improve the screening effect.
[0032] Similarly, the water mixed with the liquid with smaller particles after the first screening process passes through the first cone screen 32 and drips onto the second cone screen 33 for the second screening process. The solid particles in the liquid with a diameter larger than the mesh of the second cone screen 33 will slide along the inclined inner mesh surface and adhere to the inner surface of the second cone screen 33. It can be considered that the solid particles after the second screening process are already relatively small and it is difficult to roll down along the inner surface of the cone screen under the condition of water adhesion. Of course, after the entire screening process is completed, all the cone screens can be taken out, and the solid particles after the second screening process can be collected and obtained from the inner surface of the second cone screen 33. In addition, after the second screening process, there will still be finer solid particles and water, but because the content of metal elements is too low, it has no analytical value, so the mixed liquid can be directly discharged from the shell 31 through the outlet (such as the drain pipe 36) provided by the shell 31.
[0033] In addition, the top of the housing 31 in this embodiment has a detachable end plate, which is convenient for taking out the first conical screen 32 and the second conical screen 33 from the housing 31 to scrape or clean the solid particles attached to the screen. For example, a longer scraper can be manually inserted into the conical screen to carefully scrape off the solid particles on the inner surface. The size of the scraper needs to take into account the size of the conical screen. When cleaning the second conical screen 33, it is necessary to refer to the spacing between the first conical screen 32 and the second conical screen 33 to avoid the scraper being too wide and rubbing against the outer surface of the first conical screen 32. The scraped solid particles are collected and stored accordingly to increase the inventory of the test sample.
[0034] As a preferred embodiment, a solid guide groove 35 is provided below the open end of the first conical screen 32, and the solid guide groove 35 is provided outside the housing 31. In order to facilitate the collection of solid particles that slide out of the first conical screen 32, a solid guide groove 35 is provided below the open end of the first conical screen 32, so that the particles that slide out are transported to other collection containers through the groove body, which is convenient for subsequent analysis and processing.
[0035] Specifically, one end of the second conical screen 33 facing the driving motor 34 is a closed end, and one end of the second conical screen 33 facing away from the driving motor 34 is an open end.
[0036] As a preferred embodiment, the sample storage box 20 is embedded in the top of the rack 10, thereby improving the stability of the installation.
[0037] As a preferred embodiment, the sample storage box 20 is placed at an angle, and the lowest end of the sample storage box 20 is connected to the guide pipe 40 for the smooth discharge of the sediment sample.
[0038] As a preferred embodiment, the housing 31 is tilted, and a drain pipe 36 is provided at the bottom of the lowest end of the housing 31 to facilitate the discharge of the liquid produced after the second screening process out of the device. After the second screening process, there will still be finer solid particles and water, but because the content of the components is too low, it has no analytical value, so the mixed liquid can be directly discharged from the housing 31.
[0039] As a preferred embodiment, a plurality of rollers 50 are provided at the bottom of the frame 10 to facilitate the movement of the entire device and improve the convenience of use.
[0040] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
