Description

Technical Field

[0001] This utility model relates to the field of microplastic enrichment technology, specifically a microplastic enrichment device. Background Technology

[0002] Currently, with the widespread use and disposal of plastic products, microplastic pollution has become increasingly prominent, becoming a major environmental issue of global concern. Microplastics are widely present in water bodies, soil, air, and organisms, posing a potential threat to ecosystems and human health. In particular, in the aquatic environment, microplastics not only directly affect the survival and reproduction of aquatic organisms, but may also be transmitted through the food chain, ultimately harming human health.

[0003] When treating water containing a large amount of microplastics, existing enrichment devices often face the problem of increased flow resistance and decreased treatment efficiency due to the accumulation of microplastics on the surface of the filter media. Under long-term operation, the clogging of the filter media not only affects the enrichment effect but may also cause device failure and increase maintenance costs. At the same time, existing technologies lack effective means for cleaning and regenerating filter media, which limits the continuous operation capability and service life of the enrichment device.

[0004] Therefore, we propose a microplastic enrichment device that can continuously filter microplastics inside the liquid while cleaning the inner wall of the filter cartridge, thereby increasing the device's service life. Utility Model Content

[0005] The purpose of this invention is to provide a microplastic enrichment device that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a microplastic enrichment device, comprising an enrichment box, wherein a first channel is provided on one side of the enrichment box and a second channel is provided on the other side of the enrichment box, wherein an electric valve is fixedly installed on one side of both the first channel and the second channel, wherein filter cartridges are distributed inside both the first channel and the second channel, and two sets of filter cartridges are connected by a tensioning assembly, and a drain pipe is connected to one end of the enrichment box.

[0007] Optionally, the tensioning assembly includes a limiting cover fixedly installed on the top of both sets of filter cartridges, a fixing member fixedly installed on one side of the top of both sets of limiting covers, a pull rope fixedly installed between the two sets of fixing members, and a pulley rotatably installed on one side of the middle of the enrichment box.

[0008] By adopting the above technical solution, the two sets of filter cartridges can move up and down.

[0009] Optionally, the pulley is movably connected to the pull rope, and the two sets of limiting covers are slidably connected to the inner walls of the first channel and the second channel, respectively.

[0010] By adopting the above technical solution, the filter cartridge can be supported.

[0011] Optionally, the enrichment box has an external thread at the other end, and a connecting cover is installed on the outer thread of the external thread. The other end of the connecting cover is connected to an inlet pipe.

[0012] By adopting the above technical solution, it is easy to install and disassemble the filter cartridge.

[0013] Optionally, cleaning components are fixedly installed on both sides of the inner wall of the enrichment box, and the two sets of cleaning components are distributed in correspondence with the inner cavities of the two sets of filter cartridges.

[0014] Optionally, the cleaning assembly includes a mounting bracket fixedly installed on one side of the inner wall of the enrichment box, a mounting hole opened on one side of the mounting bracket, a support that can be detachably installed inside the mounting hole, and cleaning brushes fixedly installed at the bottom of two sets of the support, with the two sets of cleaning brushes corresponding to the inner cavities of the two sets of filter cartridges respectively.

[0015] By adopting the above technical solution, the inner wall of the filter cartridge can be cleaned.

[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0017] The technical solution of this application works by continuously circulating liquid through the first channel. Microplastics contained in the liquid are filtered by the filter cartridges distributed in the first channel. At the same time, after a large amount of microplastics are filtered out from the inner wall of the filter cartridge, a large amount of microplastics will adhere to the inner wall of the filter cartridge. The liquid inside the first channel will continuously squeeze the filter cartridge, pushing the filter cartridge to move continuously in the direction of liquid flow. Since there is a pull rope connecting the two sets of filter cartridges, when one set of filter cartridges moves downward, the other set of filter cartridges will move upward in the opposite direction and dock with the cleaning component to clean the microplastics adhering to the inner wall of the filter cartridge, thus preventing a large amount of microplastics from adhering to the inner wall of the filter cartridge and affecting the liquid flow inside the enrichment box.

[0018] The enrichment box has cleaning components fixedly installed on both sides of its inner wall, and the two sets of cleaning components are distributed in correspondence with the inner cavities of the two sets of filter cartridges. When one set of filter cartridges moves upward, the filter cartridge will continuously approach the cleaning brush at the bottom of the cleaning component. After the outer side of the cleaning brush contacts the inner wall of the filter cartridge, the microplastics adhering inside the filter cartridge can be cleaned and concentrated on the bottom side of the filter cartridge, so that the liquid can be smoothly discharged from the side wall of the filter cartridge. Repeated operation can increase the service life of the device and reduce the number of times the filter cartridges need to be cleaned. Attached Figure Description

[0024] Please see Figure 1-3 This utility model provides a technical solution: a microplastic enrichment device, including an enrichment box 1, a first channel 11 is opened on one side of the enrichment box 1, and a second channel 12 is opened on the other side of the enrichment box 1. An electric valve 24 is fixedly installed on one side of the first channel 11 and the second channel 12. Filter cartridges 13 are distributed inside the first channel 11 and the second channel 12. The two sets of filter cartridges 13 are connected by a tensioning assembly. A drain pipe 16 is connected to one end of the enrichment box 1. The tensioning assembly includes a limiting cover 2 fixedly installed on the top of the two sets of filter cartridges 13, a fixing member 21 fixedly installed on one side of the top of the two sets of limiting covers 2, a pull rope 22 fixedly installed between the two sets of fixing members 21, and a pulley 23 rotatably installed on one side of the middle of the enrichment box 1, so that the two sets of filter cartridges 13 can move up and down.

[0025] As the liquid continuously flows through the first channel 11, the microplastics contained in the liquid are filtered by the filter cartridges 13 distributed in the first channel 11. At the same time, after a large amount of microplastics are filtered out from the inner wall of the filter cartridge 13, a large amount of microplastics will adhere to the inner wall of the filter cartridge 13. The liquid inside the first channel 11 will continuously squeeze the filter cartridge 13, pushing the filter cartridge 13 to move continuously in the direction of liquid flow. Since the two sets of filter cartridges 13 are connected by a pull rope 22, when one set of filter cartridges 13 moves downward, the other set of filter cartridges 13 will move upward in the opposite direction and dock with the cleaning component to clean the microplastics adhering to the inner wall of the filter cartridge 13, so as to avoid a large amount of microplastics adhering to the inner wall of the filter cartridge 13 and affecting the liquid flow inside the enrichment box 1.

[0026] In this technical solution, cleaning components are fixedly installed on both sides of the inner wall of the enrichment box 1. The two sets of cleaning components are distributed and correspond to the inner cavities of the two sets of filter cartridges 13. The cleaning components include a mounting bracket 3 fixedly installed on one side of the inner wall of the enrichment box 1, a mounting hole 31 opened on one side of the mounting bracket 3, a bracket 32 ​​that can be detachably installed inside the mounting hole 31, and a cleaning brush 33 fixedly installed at the bottom of the two sets of brackets 32. The two sets of cleaning brushes 33 correspond to the inner cavities of the two sets of filter cartridges 13 respectively, and can clean the inner wall of the filter cartridges 13.

[0027] As a set of filter cartridges 13 moves upward, the filter cartridges 13 will continuously approach the cleaning brushes 33 at the bottom of the cleaning assembly. After the outer side of the cleaning brushes 33 contacts the inner wall of the filter cartridge 13, the microplastics adhering inside the filter cartridge 13 can be cleaned and concentrated on the bottom side of the filter cartridge 13, so that the liquid can be smoothly discharged from the side wall of the filter cartridge 13. Repeated operation can increase the service life of the device and reduce the number of times the filter cartridges 13 need to be cleaned.

[0028] In this technical solution, the pulley 23 is movably connected to the pull rope 22, and the two sets of limiting covers 2 are slidably connected to the inner walls of the first channel 11 and the second channel 12 respectively, which can support the filter cartridge 13.

[0029] When the filter cartridges 13 inside the first channel 11 and the second channel 12 move up and down, the limiting covers 2 fixedly installed on the top of the two sets of filter cartridges 13 are slidably connected to the inner walls of the first channel 11 and the second channel 12 respectively, which can support and limit the filter cartridges 13.

[0030] In this technical solution, the other end of the enrichment box 1 is provided with an external thread, and a connecting cover 14 is installed on the outer side of the external thread. The other end of the connecting cover 14 is connected to an inlet pipe 15, which facilitates the installation and disassembly of the filter cartridge 13.

[0031] Because the opening at one end of the enrichment box 1 is relatively large, after the connecting cover 14 on one side of the liquid inlet pipe 15 is screwed on, it is easy for the operator to take out the filter cartridge 13 for cleaning.

[0032] In use, first open the electric valve 24 on the first channel 11 and close the electric valve 24 on the second channel 12. The liquid inside the inlet pipe 15 will continuously flow from the first channel 11 inside the enrichment box 1 into the drain pipe 16. Since filter cartridges 13 are distributed inside both the first channel 11 and the second channel 12, when the liquid continuously flows from the first channel 11, the microplastics contained in the liquid will be filtered by the filter cartridges 13 distributed in the first channel 11. At the same time, after a large amount of microplastics are filtered out from the inner wall of the filter cartridge 13, a large amount of microplastics will adhere to the inner wall of the filter cartridge 13. The liquid inside the first channel 11 will continuously squeeze the filter cartridge 13, pushing the filter cartridge 13 to move continuously in the direction of liquid flow. Since the two sets of filter cartridges 13 are connected by a pull rope 22, when the first set of filter cartridges 13 moves downwards... Meanwhile, another set of filter cartridges 13 will move upwards in the opposite direction and dock with the cleaning component to clean the microplastics adhering to the inner wall of the filter cartridge 13. This prevents a large amount of microplastics from adhering to the inner wall of the filter cartridge 13 and affecting the flow of liquid inside the enrichment box 1. At the same time, cleaning components are fixedly installed on both sides of the inner wall of the enrichment box 1, and the two sets of cleaning components are distributed and correspond to the inner cavities of the two sets of filter cartridges 13. When one set of filter cartridges 13 moves upwards, the filter cartridge 13 will continuously approach the cleaning brush 33 at the bottom of the cleaning component. After the outer side of the cleaning brush 33 contacts the inner wall of the filter cartridge 13, the microplastics adhering to the inside of the filter cartridge 13 can be cleaned and concentrated on the bottom side of the inside of the filter cartridge 13, so that the liquid can be smoothly discharged from the side wall of the filter cartridge 13. Repeated operation can increase the service life of the device and reduce the number of times the filter cartridges 13 need to be cleaned.
