[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.
[0031] As Figures 1 - 8 shown, the present invention provides a technical solution: a solid-liquid separation device, including a top separation device 1, a sheath 2, a detection device 3 and a bottom separation device 4. The top separation device 1 is arranged at the top of the sheath 2. The detection device 3 and the bottom separation device 4 are both arranged inside the sheath 2. The detection device 3 is sleeved on the surface of the sheath 2. The bottom of the top separation device 1 is connected to the top of the detection device 3. The bottom of the detection device 3 is connected to the top of the bottom separation device 4.
[0032] The top separation device 1 includes a top side ring 11. A fixed folding rod 12 is fixedly connected to the side surface of the top side ring 11. A limiting ring 19 is fixedly connected to the side surface of the fixed folding rod 12. The limiting ring 19 is sleeved on the surface of the sleeve 2. The sleeve 2 is slidably connected to the surface of the fixed folding rod 12. A folding piece 10 is fixedly connected to the top of the sleeve 2. A through hole 101 is formed in the surface of the folding piece 10. One side of the folding piece 10 away from the sleeve 2 is connected to the top side ring 11. A connecting plate 103 is slidably connected to one side of the top side ring 11. A retention strip 14 is fixedly connected to the top of the connecting plate 103. A connector 13 is fixedly connected to the top of the retention strip 14. One end of the connector 13 away from the retention strip 14 is fixedly connected to a drainage groove 18. One end of the drainage groove 18 close to the limiting ring 19 is connected to the folding piece 10. The drainage groove 18 is sleeved in the through hole 101. A filter screen 15 is fixedly connected to the surface of the retention strip 14. An upper retention platform 16, a middle retention platform 17 and a lower retention platform 102 are respectively fixedly connected to the side surface of the retention strip 14. The bottom of the lower retention platform 102 is fixedly connected to the detection device 3. By having solids retained above the filter screen 15, the retention strip 14 allows solids with a greater weight to slide downward along its body, while solids with a lighter weight will stay on the surface of the retention strip 14. The purpose of this is to let larger solids accumulate below the top separation device 1 and prevent smaller solids from accumulating below and causing blockage, so that the liquid cannot flow out of the top separation device 1.
[0033] The slopes of the upper retention platform 16, the middle retention platform 17 and the lower retention platform 102 are gradually gentler in sequence, so as to enable solids of different sizes to be collected in layers, and they are arranged from top to bottom in ascending order of size.
[0034] When the drainage groove 18 reaches the top of the limiting ring 19, the folding piece 10 will be pulled by the drainage groove 18 and unfold. At the same time, the connector 13 will hang on the top side ring 11. In addition, the connecting plate 103 will move downward away from the top side ring 11 and expose the through hole 101, so as to achieve the effect of allowing excessive accumulated solids to flow out along the drainage groove 18 through the through hole 101.
[0035] The detection device 3 includes a central column 31. A spiral auger 32 is fixedly connected to the surface of the central column 31. One side of the spiral auger 32 away from the central column 31 is fixedly connected to a middle cylinder 33. The top of the middle cylinder 33 is fixedly connected to the bottom of the lower retention table 102. A partition plate 34 is fixedly connected to the side of the middle cylinder 33. A layered body 35 is fixedly connected to the side of the partition plate 34. One side of the layered body 35 is connected to the inner wall of the housing 2. Upper partition plates 38 and lower partition plates 39 are respectively arranged on the surface of the layered body 35. Both ends of the upper partition plate 38 are connected to the partition plate 34. Both ends of the lower partition plate 39 are connected to the partition plate 34. A syringe 36 is sleeved on the surface of the housing 2. The syringe 36 penetrates through the surface of the layered body 35 and extends into the interior. One end of the syringe 36 close to the lower partition plate 39 is fixedly connected to a swing bar 37. By pushing and swinging the syringe 36, the swing bar 37 arranged at the front end of the syringe 36 can better make the medicament react with the liquid. Among them, the upper partition plate 38 and the lower partition plate 39 play a role in re-dividing the interior of the layered body 35 to achieve the function of sample detection for the separated liquid.
[0036] The bottom separation device 4 includes a loading platform 41. A rotating partition layer 42 is arranged on the top of the loading platform 41. Separation cylinders 43 are fixedly connected to both ends of the rotating partition layer 42. A water passing net 46 is opened at the bottom of the separation cylinder 43. One side of the separation cylinder 43 is slidably connected to the surface of the loading platform 41. A first round hole 47 is opened at the bottom of the loading platform 41. A reflux pipe 44 is sleeved on the surface of the first round hole 47. One end of the reflux pipe 44 away from the first round hole 47 is sleeved with a bottom hole plate 45. Both ends of the bottom hole plate 45 are respectively connected to the loading platform 41 and the housing 2. A second round hole 48 is opened on the surface of the bottom hole plate 45. The reflux pipe 44 is sleeved on the surface of the second round hole 48. The separation cylinder 43 plays a role in secondary separation of the solids inside the liquid. At the same time, the liquid will re-enter the loading platform 41 through the reflux pipe 44, causing the liquid in the loading platform 41 to surge from bottom to top, so as to achieve the function of pushing the floating impurities on the surface of the loading platform into the separation cylinder 43.
[0037] During use, by pouring the solid-liquid mixture into the top separation device 1, the liquid will enter the detection device 3 through the filter screen 15 at this time, while the solid will remain above the filter screen 15. The function of the retention strip 14 is to slide the heavier solid downward along the body of the retention strip 14, while the lighter solid will stay on the surface of the retention strip 14. The purpose of this is to let the larger-volume solids accumulate below the top separation device 1, preventing the smaller-volume solids from accumulating below and causing blockage, so that the liquid cannot flow out of the top separation device 1. In addition, the slopes of the upper retention table 16, the middle retention table 17, and the lower retention table 102 are gradually gentle in sequence, so as to enable the solids of different volumes to be collected in layers, and the volumes are arranged from small to large from top to bottom in sequence.
[0038] Through the accumulation of solids on the top separation device 1, when the solids accumulate to a certain extent, the connecting plate 103 will slide downward along the surface of the top side ring 11. There is a retention strip 14 provided at the top of the connecting plate 103, and the top of the retention strip 14 is connected to the connector 13, and the other end of the connector 13 is connected to the drainage groove 18. Therefore, the drainage groove 18 will move downward and pull the folding piece 10, causing the folding piece 10 to open. The limiting ring 19 functions to limit the further downward movement of the drainage groove 18, and the connector 13 functions to connect the retention strip 14 and the drainage groove 18. When the drainage groove 18 reaches the top of the limiting ring 19, the folding piece 10 will be pulled by the drainage groove 18 and unfold. At the same time, the connector 13 will hang on the top side ring 11. In addition, the connecting plate 103 will move downward away from the top side ring 11 and expose the through hole 101, so as to allow the excessively accumulated solids to flow out along the drainage groove 18 through the through hole 101.
[0039] By the liquid flowing into the detection device, part of the liquid will flow downward along the spiral auger 32, while the other part of the liquid will enter the stratifying body 35. At this time, the liquid entering the stratifying body 35 will be divided into four parts from bottom to top in sequence, and then push the syringe 36 and swing the syringe, so that the swing bar 37 provided at the front end of the syringe 36 can better make the chemical reagent react with the liquid. The upper partition plate 38 and the lower partition plate 39 function to re-divide the inside of the stratifying body 35, so as to achieve taking samples of the clear liquid at different heights after the separated liquid is statically settled.
[0040] The liquid flowing out of the auger 32 will have rotational inertia force, so the liquid will impact the rotating partition layer 42, causing the rotating partition layer to drive the separation cylinder 43 to rotate on the loading platform 41. Part of the remaining liquid will enter the loading platform 41, and the other part will enter the separation cylinder 43. There is a water-passing net 46 in the separation cylinder 43, so the separation cylinder 43 plays a role in secondary separation of the solids inside the liquid. At the same time, the liquid will re-enter the loading platform 41 through the return pipe 44, causing the liquid in the loading platform 41 to surge from bottom to top, so as to push the floating impurities on the surface of the loading platform into the separation cylinder 43.
[0041] Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative work shall fall within the scope of protection of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented by conventional means in the art without special instructions and limitations.
