[0002] With the rapid development of the economy, the wide use of plastics and their products has increased the proportion of plastic waste. Due to the characteristics of plastics such as difficult decomposition and low recycling rate, serious environmental pollution problems have been caused, especially in the garbage-polluted basins. The natural decomposition of plastics and improper treatment methods will produce a class of emerging pollutants, microplastics, which are currently widely distributed in various water and soil environments.
[0003] Microplastics generally refer to plastic particles with a particle size less than 5 mm, which have hydrophobicity, persistence and difficult degradability, and are difficult to recover from water bodies. At present, most of the treatments for microplastics adopt two methods: physical filtration and chemical treatment. Among them, physical filtration treatment has certain advantages. However, due to the difference in the particle size of microplastic particles, when physical filtration is carried out, the problem of filter screen blockage often occurs, which makes the filtration unable to be carried out for a long time, greatly affecting the microplastic conditioning effect.

Detailed implementation manner
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] The following gives specific embodiments.
[0024] Such as Figures 1 to 3As shown in the figure, a microplastic pollution basin conditioning device according to an embodiment of the present utility model includes a water pump 23; two sides of the water pump 23 are fixedly connected with a water inlet pipe 1 and a filter pipe 2 correspondingly; the end of the filter pipe 2 away from the water pump 23 is fixedly connected with a coarse filter chamber 4; a coarse filter screen 6 is arranged inside the coarse filter chamber 4; a dense filter hole is arranged on the surface of the coarse filter screen 6; the top of the coarse filter screen 6 is arranged corresponding to the inner contour of the filter pipe 2; a connecting pipe 24 is fixedly connected to the side of the coarse filter chamber 4 corresponding to the position of the filter pipe 2; two ends of the connecting pipe 24 away from the coarse filter chamber 4 are fixedly connected with a fine filter chamber 5; a fine filter screen 7 is arranged inside the two fine filter chambers 5; a dense filter hole is arranged on the surface of the fine filter screen 7; the tops of the two fine filter screens 7 are arranged corresponding to the inner contour of the connecting pipe 24; a drain pipe 3 is fixedly connected to the side of the connecting pipe 24 away from the coarse filter chamber 4; during operation, the staff can drive the water pump 23 to transport the water body in the water area through the water inlet pipe 1 and the filter pipe 2 to the inside of the coarse filter chamber 4. When the water body passes through the inside of the coarse filter chamber 4, it first accumulates at the bottom of the coarse filter chamber 4 and the coarse filter screen 6. When the internal space of the coarse filter chamber 4 and the coarse filter screen 6 is filled with the water body, the water body moves towards the connecting pipe 24 through the filter holes on the surface of the coarse filter screen 6. When the water body passes through the filter screen of the coarse filter screen 6, some larger microplastic particles cannot pass through and accumulate at the bottom of the coarse filter chamber 4 and the coarse filter screen 6 immediately. Under the continuous action of the water pump 23, the water body enters the two fine filter chambers 5 through the connecting pipe 24 and repeatedly passes through the filter holes on the surfaces of the two fine filter screens 7, depositing the remaining smaller microplastic particles at the bottom of the fine filter chamber 5 and the fine filter screen 7. The water body passes through the drain pipe 3 and returns to the water area again; through the above structure in this step, the scenario that larger microplastic particles cover the filter screen during the microplastic filtration process, resulting in the rapid failure of the filter screen, is avoided. With the help of the coarse filter screen 6 and the two fine filter screens 7, it is beneficial to enhance the filtration effect of microplastics, extend the service time and effective duration of the filter screen, and thus efficiently condition the microplastic particles in the polluted water area.
[0025] As Figures 1 to 3As shown, a first fixing ring 8 is fixedly connected to the bottoms of the coarse filtration chamber 4 and the fine filtration chamber 5; a bolt 13 is fixedly connected to the top of the first fixing ring 8; a plurality of the bolts 13 are arranged in a circumferential array; a second fixing ring 9 is fixedly connected to the bottom of the bolt 13; the second fixing ring 9 is fixedly connected to the top of the sedimentation box 10; a support mesh platform 11 is fixedly connected to the inside of the sedimentation box 10; the top of the support mesh platform 11 located at the bottom of the coarse filtration chamber 4 supports the bottom of the coarse filter screen 6; the top of the support mesh platform 11 located at the bottom of the fine filtration chamber 5 supports the bottom of the fine filter screen 7; during operation, the staff can regularly replace the coarse filter screen 6 in the coarse filtration chamber 4 and the fine filter screen 7 in the fine filtration chamber 5; whenever the microplastic conditioning work lasts for a certain period of time, or when the filtering effect of the device decreases, the polluted water area conditioner can remove the bolt 13 to separate the first fixing ring 8 from the second fixing ring 9. After the first fixing ring 8 and the second fixing ring 9 are separated, the sedimentation box 10 will immediately detach, and the coarse filter screen 6 and the fine filter screen 7 will lose the support of the support mesh platform 11 inside the sedimentation box 10 and then detach. After completing the above work, the conditioner can replace the coarse filter screen 6 that has detached from the coarse filtration chamber 4, replace the fine filter screen 7 that has detached from the fine filtration chamber 5, and clean the microplastic particles inside the coarse filtration chamber 4 and the fine filtration chamber 5. After cleaning, install the spare coarse filter screen 6 and fine filter screen 7; through the above structure in this step, the problem that the filter screen inside the microplastic conditioning device cannot be replaced is solved, and the scenario where the filter screen is completely blocked after long-term use and cannot be used or replaced is avoided. By setting the sedimentation box 10 and the support mesh platform 11, while improving the stability of the coarse filter screen 6 and the fine filter screen 7, the coarse filter screen 6 and the fine filter screen 7 are convenient to replace, which is beneficial to long-term and high-efficiency microplastic conditioning work in polluted river basins.
[0026] As Figure 3 shown, a sealing ring 25 is fixedly connected to the bottom of the coarse filtration chamber 4; a sealing ring 25 is fixedly connected to the bottom of the fine filtration chamber 5; a sealing rubber ring 12 is fixedly connected to the inside of the sedimentation box 10; the sealing rubber ring 12 is correspondingly arranged at the bottom of the sealing ring 25; during operation, after the polluted water area microplastic conditioner installs the spare coarse filter screen 6 and fine filter screen 7 inside the coarse filtration chamber 4 and the fine filtration chamber 5, it is necessary to reinstall the sedimentation box 10 at the bottoms of the coarse filtration chamber 4 and the fine filtration chamber 5. Whenever the sedimentation box 10 is installed at the bottom of the coarse filtration chamber 4 or the fine filtration chamber 5, the sealing rubber ring 12 first comes into contact with the sealing ring 25, and the staff fixes the first fixing ring 8 and the second fixing ring 9 through a plurality of bolts 13, and the sealing rubber ring 12 and the sealing ring 25 are squeezed against each other to block the water body; through the above structure in this step, the water body is prevented from overflowing through the gaps between the device components under the action of water pressure and damaging the device. By setting the sealing rubber ring 12 and the sealing ring 25, and the two are squeezed against each other by means of the bolt 13, it is beneficial to enhance the tightness of the device and prevent the water body from overflowing and damaging the device.
[0027] As Figure 1 andFigure 4 As shown, the end of the water inlet pipe 1 far from the water pump 23 is fixedly connected with a water tower 14; the top of the water tower 14 is fixedly connected with a water surface suction cup 26; the bottom of the water tower 14 is fixedly connected with a support column 15; the support column 15 is slidably connected with a telescopic rod 16; during operation, the microplastic conditioner in the polluted area can insert the telescopic rod 16 into the water ground and fix the water tower 14 and the water surface suction cup 26 below the water surface. After fixation, the water pump 23 can be driven to transport the water body through the water surface suction cup 26 and the water tower 14 into the water inlet pipe 1. In this step, by setting the water surface suction cup 26 at the top of the water tower 14 and the support column 15 and the telescopic rod 16 at the bottom of the water tower 14, the water suction component of the device can suck water at a certain position below the water surface, avoiding the mixing of bottom sludge into the device, which is beneficial to the device to efficiently suck the water body with a higher microplastic content, thereby improving the microplastic conditioning rate.
[0028] As Figure 1 shown in Figure 4 As shown, a barrier 18 is fixedly connected to the top of the water surface suction cup 26; a plurality of the barriers 18 are arranged in a circumferential array; a stirrup 27 is arranged on the top of the water surface suction cup 26; the stirrup 27 is fixedly connected to the side of the barrier 18; during operation, under the action of the water pump 23, the water body quickly passes through the water surface suction cup 26 and the water tower 14, and the water plants and sundries on the water surface move towards the top of the water surface suction cup 26 at the same time. When the water plants and sundries reach the top of the water surface suction cup 26, they will be blocked by the barrier 18 and the stirrup 27, so as to be isolated outside the water surface suction cup 26. In this step, by setting the barrier 18 and the stirrup 27 to block the sundries on the water surface, the sundries are prevented from blocking the water surface suction cup 26, which is beneficial to the long-term operation of the water pump 23 and ensures the efficient progress of microplastic conditioning.
[0029] As Figure 4As shown, the top of the telescopic rod 16 is fixedly connected to a limit block 22; the limit block 22 is slidably connected to the inside of the support column 15; the side of the support column 15 is fixedly connected to a fixed protrusion 20; a clamping block 17 is arranged inside the fixed protrusion 20; the clamping block 17 is slidably connected to the telescopic rod 16; the internal teeth of the fixed protrusion 20 are connected to a telescopic valve 21; during work, the staff can adjust the overall length of the support column 15 and the telescopic rod 16. When the water depth is deep or shallow, the water surface suction cup 26 cannot be placed in the predetermined position, and the telescopic valve 21 can be controlled 1 is away from the block 17. After the block 17 loses the pressure of the telescopic valve 21, the telescopic rod 16 loses its restriction, and the limit block 22 can move freely inside the support column 15. After the overall length of the support column 15 and the telescopic rod 16 changes, the staff can control the telescopic valve 21 to re-press the block 17 to fix this length; this step controls the overall length of the support column 15 and the telescopic rod 16 through the setting of the block 17 and the telescopic valve 21, and changes the situation where the components cannot be used when the water depth is too shallow or too deep, which is conducive to improving the applicability of the device and ensuring the normal microplastic conditioning work.
[0030] like Figure 1 and Figure 4 As shown, a connecting rod is fixedly connected to the top of the water tower 14; a signal light 19 is fixedly connected to the top of the connecting rod; when working, the staff can drive the signal light 19 to work at night, and use the signal light 19 to determine the night position and working status of the water tower 14 in real time; this step provides a reminder of the night situation of the component by setting the signal light 19, thereby improving the functionality of the device.
[0031] When working, the staff can drive the water pump 23 to transport the water body in the water area through the water inlet pipe 1 and the filter pipe 2 to the inside of the coarse filtration chamber 4. When the water body passes through the inside of the coarse filtration chamber 4, it first accumulates at the bottom of the coarse filtration chamber 4 and the coarse filter screen 6. When the internal space of the coarse filtration chamber 4 and the coarse filter screen 6 is filled with the water body, the water body passes through the surface filter holes of the coarse filter screen 6 and moves towards the connecting pipe 24. When the water body passes through the filter screen of the coarse filter screen 6, some larger microplastic particles cannot pass through and immediately accumulate at the bottom of the coarse filtration chamber 4 and the coarse filter screen 6. Under the continuous action of the water pump 23, the water body enters the inside of the two fine filtration chambers 5 through the connecting pipe 24 and repeatedly passes through the surface filter holes of the two fine filter screens 7, depositing the remaining smaller microplastic particles at the bottom of the fine filtration chamber 5 and the fine filter screen 7. The water body passes through the drain pipe 3 and returns to the water area again. The staff can regularly replace the coarse filter screen 6 in the coarse filtration chamber 4 and the fine filter screen 7 in the fine filtration chamber 5;Whenever the microplastic conditioning work lasts for a certain period of time or the filtering effect of the device decreases, the polluted water area conditioner can remove the bolt 13 to separate the first fixing ring 8 from the second fixing ring 9. After the first fixing ring 8 is separated from the second fixing ring 9, the sediment box 10 will immediately detach. Without the support of the support mesh platform 11 inside the sediment box 10, the coarse filter screen 6 and the fine filter screen 7 will also detach. After completing the above work, the conditioner can replace the coarse filter screen 6 separated from the coarse filter chamber 4 and the fine filter screen 7 separated from the fine filter chamber 5, and clean the microplastic particles inside the coarse filter chamber 4 and the fine filter chamber 5. After cleaning, install the spare coarse filter screen 6 and fine filter screen 7. After installing the spare coarse filter screen 6 and fine filter screen 7 inside the coarse filter chamber 4 and the fine filter chamber 5, the polluted water area conditioner needs to reinstall the sediment box 10 at the bottom of the coarse filter chamber 4 and the fine filter chamber 5. Whenever the sediment box 10 is installed at the bottom of the coarse filter chamber 4 or the fine filter chamber 5, the sealing rubber ring 12 will first come into contact with the sealing ring 25. The staff fixes the first fixing ring 8 and the second fixing ring 9 with multiple bolts 13, and the sealing rubber ring 12 and the sealing ring 25 will be squeezed against each other to block the water. The polluted water area conditioner can insert the telescopic rod 16 into the water and fix the water tower 14 and the water surface suction cup 26 at a position below the water surface. After fixing, the water pump 23 can be driven to transport the water through the water surface suction cup 26 and the water tower 14 to the inside of the water inlet pipe 1. Under the action of the water pump 23, the water quickly passes through the water surface suction cup 26 and the water tower 14, and the water plants and sundries on the water surface will move towards the top of the water surface suction cup 26 at the same time. When the water plants and sundries reach the top of the water surface suction cup 26, they will be blocked by the obstacle bar 18 and the stirrup 27 and thus be isolated outside the water surface suction cup 26. The staff can adjust the overall length of the support column 15 and the telescopic rod 16. When the water depth is too deep or too shallow, the water surface suction cup 26 cannot be placed at the predetermined position. The expansion valve 21 can be controlled to move away from the block 17. After the block 17 loses the pressure of the expansion valve 21, the telescopic rod 16 is no longer restricted, and the limit block 22 can move freely inside the support column 15. After the overall length of the support column 15 and the telescopic rod 16 changes, the staff can control the expansion valve 21 to press the block 17 again to fix this length. The staff can drive the signal lamp 19 to work at night and use the signal lamp 19 to determine the night position and working conditions of the water tower 14 in real time.;
