Description

Technical Field

[0001] The invention belongs to the technical field of solid-liquid separation, and in particular relates to an environmentally friendly solid-liquid separation device and a separation method. Background Art

[0002] The solid-liquid separation device is a device that uses a separation device to separate solid particles and liquids. Its working principle is based on the microporous structure and surface adsorption characteristics of the separation device. Through physical interception, surface adsorption and deep filtration mechanisms, it can effectively separate the solid-liquid mixture to achieve the purpose of environmental protection and purification.

[0003] However, in the prior art, when solid-liquid mixtures are subjected to solid-liquid filtration separation, most of the solid-liquid mixtures are allowed to flow through a separation device, solid particles are retained, and liquid passes through the separation device, thereby achieving solid-liquid separation. In the process, since solid particles are retained in the separation device, as the filtration time goes by, the solid particles gradually increase, gradually clogging the filter holes, reducing the flow rate of the liquid through the filter holes, resulting in poor solid-liquid separation, thereby reducing the separation efficiency of the solid-liquid mixture. The existing separation device needs to replace the filter component regularly during the processing process to ensure that the equipment can work stably for a long time.

[0037] The above scheme is adopted: the outer wall of the third push plate 1014 can be clamped with the second push plate 1012, so that the elastic band 1013 can limit and fix the third push plate 1014 and the second push plate 1012, and the second push plate 1012 limits and pulls the third push plate 1014, and the third push plate 1014 can be reset and pulled into the interior of the second push plate 1012 through the second push plate 1012, and the folding plate 1015 can prevent the third push plate 1014 and the second push plate 1012 from pushing solid particles. The two second push plates 1012 and the two third push plates 1014 are mutually The second push plate 1012 and the third push plate 1014 are pulled and fixed so as to slide outward along the inside of the first push plate 1011, so that the folding plate 1015 is extended. When the movable ring 7 moves down to the bottom end of the rotating cylinder 5, the folding tube 6 extends downward, and the push rod 912 is parallel to the filter plate 11. The first push plate 1011 is moved to the edge of the filter plate 11 through the push rod 912. In this process, the first push plate 1011, the second push plate 1012 and the third push plate 1014 push the solid particles trapped on the top of the filter plate 11 into the collecting cylinder 12. The two second push plates 1012 are fixedly connected, and the two third push plates 1014 are fixedly connected.

[0038] like Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the scraper assembly 13 includes a first fixed shaft 1311, the outer wall of the first fixed shaft 1311 is fixedly connected to the first gear 1312, the outer edge of the first gear 1312 is meshed with the second gear 1313, the outer edge of the second gear 1313 is meshed with the gear ring 1314, the middle part of the second gear 1313 is fixedly connected to the second fixed shaft 1315, the top of the first fixed shaft 1311 is fixedly connected to the rotating cylinder 5, the outer wall of the first fixed shaft 1311 is rotatably connected to the filter plate 11, the first gear 1312, the second gear 1313 and the gear ring 1314 are all located inside the filter plate 11, the bottom end of the first fixed shaft 1311 is movably connected to the scraper rod 14, the outer wall of the gear ring 1314 is fixedly connected to the filter plate 11, the outer wall of the second fixed shaft 1315 is movably connected to the filter plate 11, and the bottom end of the second fixed shaft 1315 is movably connected to the scraper rod 14;

[0040] According to the above scheme, the rotating drum 5 drives the first gear 1312 to rotate through the first fixed shaft 1311, the first gear 1312 is meshed with the second gear 1313 to rotate the second gear 1313, the second gear 1313 is meshed with the gear ring 1314 so that the second gear 1313 rotates along the inner wall of the gear ring 1314 while the first gear 1312 rotates, the second gear 1313 drives the scraper rod 14 to rotate through the second fixed shaft 1315, so that the scraper rod 14 scrapes off the solid-liquid mixture attached to the bottom of the filter plate 11 and makes it fall into the filter bag 15, the gear ring 1314 is limited and fixed by the filter plate 11, the first gear 1312 is located in the middle of the filter plate 11, and the second gear 1313 is meshed with the gear ring 1314 so that the second gear 1313 rotates along the inner wall of the gear ring 1314 while the first gear 1312 rotates. When the second gear 1313 rotates through the gear ring 1314, it rotates with the first fixed shaft 1311 as the center of the circle. The first fixed shaft 1311 limits the scraper rod 14, so that when the scraper rod 14 rotates through the second fixed shaft 1315 and the second gear 1313, the scraper rod 14 also rotates with the first fixed shaft 1311 as the center of the circle. The filter bag 15, the liquid collecting cylinder 16 and the drain pipe 17 can be disassembled by opening the box door 2. When the solid-liquid mixture enters the separation box 1 through the feed pipe 3 and is filtered through the filter plate 11, the oblique ring 18 can prevent the solid-liquid mixture from scattering, so that the solid-liquid mixture can be concentrated above the filter plate 11 for filtering. A one-way valve is fixedly connected to the outer wall of the drain pipe 17, and the flow of the drain pipe 17 can be controlled by the one-way valve.

[0041] like Figures 1 to 8 As shown, the present invention also proposes an environmentally friendly solid-liquid separation method, comprising the following steps:

[0042] Step 1: The solid-liquid mixture is poured into the separation box 1 through the feed pipe 3, and the solid-liquid mixture is preliminarily filtered through the filter plate 11, so that the solid particles in the solid-liquid mixture are retained by the filter plate 11, and the solid-liquid mixture after the preliminary filtration enters the filter bag 15 for secondary filtration, and the solid particles that are not fully filtered are retained by the filter bag 15 again, and the filtered liquid flows into the liquid collecting cylinder 16;

[0043] Step 2: After the solid-liquid mixture is initially filtered, the driving motor 4 drives the rotating drum 5 to rotate, the rotating drum 5 drives the moving ring 7 to move downward through the cam 8, the moving ring 7 drives the first hinge block 911 to move downward, the first hinge block 911 drives the push rod 912 to move so that the push rod 912 flips outward, the push rod 912 pushes the first push plate 1011 outward through the second hinge block 913 and the fixed plate 914, the two second push plates 1012 and the two third push plates 1014 are entangled and fixed to each other, so that the second push plates 1012 and the second push plates 1014 are fixed to each other. The push plate 1012 and the third push plate 1014 slide outward along the inside of the first push plate 1011, so that the folding plate 1015 extends. When the moving ring 7 moves down to the bottom end of the rotating cylinder 5, the folding tube 6 extends downward, the push rod 912 is parallel to the filter plate 11, and the first push plate 1011 moves to the edge of the filter plate 11 through the push rod 912. In this process, the first push plate 1011, the second push plate 1012 and the third push plate 1014 push the solid particles trapped on the top of the filter plate 11 into the collecting cylinder 12;

[0044] Step three, during the rotation of the rotating drum 5, the rotating drum 5 drives the first gear 1312 to rotate through the first fixed shaft 1311, the first gear 1312 is meshed with the second gear 1313 to rotate the second gear 1313, the second gear 1313 is meshed with the gear ring 1314 so that the second gear 1313 rotates along the inner wall of the gear ring 1314 while the first gear 1312 rotates, the second gear 1313 drives the scraper 14 to rotate through the second fixed shaft 1315, so that the scraper 14 scrapes off the solid-liquid mixture attached to the bottom of the filter plate 11, so that it falls into the filter bag 15 and is filtered through the filter bag 15. After the solid-liquid separation in the solid-liquid mixture, the solid particles are collected outward through the collecting barrel 12, and the liquid in the collecting barrel 16 can be discharged through the drain pipe 17.

[0045] Adopt the above scheme: Among them, it is worth mentioning that: the solid-liquid separation device can effectively separate solid particles from liquid. These solid particles may contain valuable resources or recyclable materials. By recycling these solids, the demand for primary resources can be reduced, and the environmental impact of mining and processing new resources can be reduced; in the separation process, the liquid part is purified, and the suspended matter, pollutants and other harmful components therein are reduced. The purified liquid can be reused in production or other purposes, such as agricultural irrigation, industrial circulating water, etc., thereby saving water resources; the environmentally friendly solid-liquid separation device can adapt to solid-liquid mixtures of different types and concentrations, and has strong adaptability, which helps to meet the needs of different industries and fields for solid-liquid separation;

[0046] By pushing a certain amount of solid particles outward through the pushing component 9 and the pushing component 10 in the device, it can be ensured that the solid-liquid separation of the filter plate 11 is smooth, thereby improving the separation efficiency of the solid-liquid mixture. At the same time, a large amount of solid particles in the solid-liquid mixture can be intercepted by the filter plate 11, which can avoid a large amount of solid particles from accumulating in the filter bag 15 and reducing the tension of the filter bag 15, thereby reducing the wear of the filter bag 15 by the solid particles, reducing the replacement frequency of the filter bag 15, and extending the service life of the filter bag 15, so as to achieve the purpose of fully using the filter bag 15. On the one hand, it can reduce the consumption of subsequent work resources. On the other hand, the long-term effective use of items reduces the generation and removal of waste, reduces the emission of waste resources, and effectively achieves the purpose of environmental protection.

10. An environmentally friendly solid-liquid separation method, using an environmentally friendly solid-liquid separation device according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: The solid-liquid mixture is poured into the separation box (1) through the feed pipe (3), and the solid-liquid mixture is preliminarily filtered through the filter plate (11), so that the solid particles in the solid-liquid mixture are intercepted by the filter plate (11), and the solid-liquid mixture after the preliminarily filtration enters the filter bag (15) for secondary filtration, and the solid particles that are not fully filtered are intercepted again by the filter bag (15), and the filtered liquid flows into the liquid collecting cylinder (16); Step 2: After the solid-liquid mixture is initially filtered, the driving motor (4) drives the rotating cylinder (5) to rotate, the rotating cylinder (5) drives the moving ring (7) to move downward through the cam (8), the moving ring (7) drives the first hinge block (911) to move downward, the first hinge block (911) drives the push rod (912) to move so that the push rod (912) flips outward, the push rod (912) pushes the first push plate (1011) outward through the second hinge block (913) and the fixed plate (914), the two second push plates (1012) and the two third push plates (1014) are entangled and fixed to each other, so that the second push plates (1012) and the third push plates (1014) are mutually engaged and fixed. The plate (1012) and the third push plate (1014) slide outward along the inside of the first push plate (1011), so that the folding plate (1015) extends. When the moving ring (7) moves down to the bottom end of the rotating cylinder (5), the folding tube (6) extends downward, the push rod (912) is parallel to the filter plate (11), and the first push plate (1011) moves to the edge of the filter plate (11) through the push rod (912). In this process, the first push plate (1011), the second push plate (1012) and the third push plate (1014) push the solid particles trapped on the top of the filter plate (11) into the inside of the collecting cylinder (12); Step 3: During the rotation of the rotating drum (5), the rotating drum (5) drives the first gear (1312) to rotate via the first fixed shaft (1311), the first gear (1312) meshes with the second gear (1313) and causes the second gear (1313) to rotate, the second gear (1313) meshes with the gear ring (1314) so ​​that the second gear (1313) rotates along the inner wall of the gear ring (1314) while the first gear (1312) rotates, the second gear (1313) drives the scraper (14) to rotate via the second fixed shaft (1315), so that the scraper (14) scrapes off the solid-liquid mixture attached to the bottom of the filter plate (11) and causes it to fall into the filter bag (15), and is filtered through the filter bag (15). After the solid and liquid in the solid-liquid mixture are separated, the solid particles are collected outward through the collecting barrel (12), and the liquid in the collecting barrel (16) is discharged through the drain pipe (17).
