Description

Technical Field

[0001] The utility model belongs to the field of microplastic classification and collection, in particular to a microplastic classification and collection device, which is used for collecting microplastics with different particle sizes. Background Art

[0002] Microplastics, i.e. plastic particles with a diameter of less than 5 mm, have become an environmental pollution issue that has attracted much attention in recent years. They are widely present in water bodies, soil, atmosphere and food chains, posing potential risks to ecosystems and human health. At present, the main sources of microplastics include: decomposition of plastic waste, plastic production and processing, vehicle and road wear, sewage treatment and discharge, plastic packaging and consumer product use. Microplastics have a variety of impacts on the environment and ecosystem. Microplastic particles can be ingested by aquatic organisms such as fish and plankton, and even enter the food chain, causing biological accumulation and transmission. This may cause physical and chemical damage to the organisms, affect their normal growth and reproduction, and threaten the balance of the ecosystem. Microplastics can quickly spread to different environmental media through transmission methods such as water flow, wind and suspension, expanding the scope of pollution and further invading freshwater resources and soil. Additives and residual substances in microplastics may release toxic substances, have toxic effects on the environment, and destroy the balance of the ecosystem. Microplastics can also be transmitted through the food chain, which may have a chain effect on the entire ecosystem. When top predators ingest prey rich in microplastics, these microplastics may accumulate in their bodies and affect their physiological functions and behaviors. In order to monitor the problem of microplastic pollution in waters, it is necessary to first strengthen monitoring and assessment, carry out large-scale surveys and monitoring to establish a microplastic pollution monitoring network, and then fully understand the distribution, source and impact of microplastics. In recent years, the collection tools and methods for microplastics in waters have gradually increased, but how to sort microplastics of different particle sizes is still a difficult problem at this stage. In the collection process, not only do we have to face the blockage of the collection equipment by floating or suspended objects such as aquatic plants, weeds, and fallen leaves, but we also have to face the tediousness and low efficiency of manual sorting. Therefore, how to use the device to quickly screen microplastics of different particle sizes in waters has become a problem that needs to be solved in this field. Utility Model Content

The thickness of the suspension board is adjustable to ensure that the fuselage can maintain an appropriate wading depth and float in the water.

[0027] Furthermore, the front filter baffle rotating shafts (8) are fixedly mounted on the left and right sides of the front end of the housing, and the front filter baffle (9) can rotate outward around the front filter baffle rotating shafts (8) to open the housing. When closed, the front filter baffle (9) is embedded in the housing, and the baffle can also effectively block suspended matter or floating matter with larger particle sizes in the water.

[0028] Furthermore, inside the fuselage shell, behind the front filter baffle (9) is a central filter collection net (10), which is designed as a three-dimensional cube and covers the entire middle of the fuselage, and has an aperture of no more than 5 mm.

[0029] Furthermore, inside the fuselage shell, behind the central filter collection net (10) is a rear filter collection net (11), which is designed as a three-dimensional cylinder and is located one on each side of the tail end of the central filter collection net (10), in the middle and rear position inside the fuselage, and has an aperture of no more than 50 μm.

[0030] Furthermore, the water pumping motor (13) itself is of waterproof design and is connected to the tail ends of two rear filter collection nets respectively through two drainage pipes (14).

[0031] Furthermore, a battery (19) is embedded in the center of the outer top of the body shell. The battery is waterproof. The battery (19) is connected to the water pumping motor (13) through a wire (20) to provide power for the water pumping motor (13).

[0034] The working principle of this water sampler is as follows:

[0035] At present, in the process of collecting microplastics of different particle sizes in water bodies, not only do we have to face the clogging of the collection instrument by floating objects or suspended objects such as aquatic plants, weeds, fallen leaves, etc., but we also have to face the cumbersomeness and low efficiency brought by manual sorting. The utility model is designed based on this point of view, and then hopes to overcome the existing shortcomings. After the collection device is placed in the predetermined water area, the power is turned on, and the pumping motor can start to operate, and the water containing microplastics can be extracted, making full use of the different pore sizes of different filter media in the device. When the water passes through the front filter baffle, the middle filter collection net, and the rear filter collection net, the device collects the microplastics in the water body according to different particle sizes in turn, and the water body is discharged from the outlet of the drainage pipeline. While discharging the water body, the backward water flow provides forward power for the entire device, which allows the device to move randomly in the water body and randomly collect microplastics in the water body, laying the foundation for subsequent microplastic research.

[0036] The working process of this water sampler is as follows:

[0037] Before placing the device into the water body, a float of appropriate thickness should be selected according to the sampling depth. After the float is selected and powered on, the device can be placed in the water body. After the device starts working, the water flow discharged from the tail of the device can push the device forward in the water body. During the forward movement, microplastics in the water body are randomly collected and classified according to different particle sizes. After the sampling is completed, the device is taken out of the water body, the power is turned off, and the front filter baffle is opened to take out the middle filter collection net and the rear filter collection net. The filter collection nets are simply cleaned separately. According to the corresponding different filter collection net apertures, microplastic samples of different particle sizes can be obtained respectively.
