[0023] This utility model provides a pretreatment device for microplastic detection, such as... Figure 1-6 As shown, the pretreatment device for microplastic detection includes: a treatment chamber 1 for pretreatment of microplastics; a cleaning chamber 2 on the treatment chamber 1 for cleaning the microplastics; a filter chamber 3 on the treatment chamber 1, in which a filter membrane holder 4 is installed for filtering the cleaned microplastics; a drying chamber 5 on the treatment chamber 1, and a heating plate 6 on the treatment chamber 1 for drying the microplastics in the drying chamber 5; a sieving mechanism on the treatment chamber 1 for sieving large particulate impurities in the microplastics; and an adjustment mechanism on the treatment chamber 1 and the filter membrane holder 4 for rotating and adjusting the filter membrane holder 4.
[0024] In this embodiment, during the pretreatment of microplastics for detection, the microplastics to be processed are placed into a sieving mechanism. The sieving mechanism removes large particles of impurities from the microplastics. The sieved microplastics then enter the cleaning chamber 2, where a corresponding cleaning agent is added to clean the microplastics. After cleaning, the cleaning chamber 2, the filtering chamber 3, and the drying chamber 5 are opened simultaneously. The cleaned microplastics, along with the cleaning agent, enter the filtering chamber 3 and are filtered through the filter membrane holder 4. The cleaned microplastics remain on the filter membrane holder 4, while the cleaning solvent is discharged from the processing chamber 1. After filtration, the bottom of the drying chamber 5 is closed, and the adjustment mechanism is used to... The filter membrane holder 4 is rotated 90 degrees to place the filtered microplastics into the drying chamber 5. Then, the top of the drying chamber 5 is closed. At this time, the heating plate 6 is activated by the controller to heat the drying chamber 5, thereby drying the microplastics in the drying chamber 5. The processing box 1 is equipped with an exhaust pipe, which is connected to the drying chamber 5. The exhaust pipe is equipped with a control valve. When drying the microplastics in the drying chamber 5, excess hot air in the drying chamber 5 can be discharged through the exhaust pipe. Through the entire device, microplastics can be pre-treated by washing, filtering and drying in one integrated manner. Large particulate impurities in microplastics can also be screened, effectively improving the pre-treatment efficiency of microplastics.

A second discharge pipe is provided on the processing box 1, which is connected to the filtering chamber 3 and the drying chamber 5. Solenoid valves are provided on both the first discharge pipe and the second discharge pipe, and the solenoid valves are used for control operation.
[0026] In this embodiment, the first and second feeding pipes facilitate the connection of the cleaning chamber 2, the filtering chamber 3, and the drying chamber 5, thereby enabling the microplastics to move from top to bottom within the processing box 1.
[0027] In a further preferred embodiment of this utility model, the screening mechanism includes: a screening box 7 fixedly installed on the top of the processing box 1, a discharge pipe installed at the bottom of the screening box 7, and the discharge pipe communicating with the processing box 1; a screening plate 8 disposed in the screening box 7, the screening plate 8 being used to screen large particulate impurities in the microplastics; and a vibration motor 9 fixedly installed at the bottom of the screening plate 8, the vibration motor 9 being used to drive the screening plate 8 to vibrate and screen the microplastics.
[0028] In this embodiment, when using the screening mechanism, the vibration motor 9 is started by the controller to drive the screening plate 8 to vibrate, so that the impurities falling on the screening plate 8 can be screened, and then the large particles of impurities in the microplastics can be screened and removed. The screened microplastics enter the cleaning chamber 2 through the discharge pipe.

The discharge port 701 is used to discharge large particulate impurities screened from the microplastics. An installation groove is provided on the inner wall of the screening box 7. A sliding rod is fixedly installed in the installation groove. A slider is fixedly installed on the screening plate 8. The slider and the sliding rod are slidably connected. A spring is sleeved on the sliding rod, and a damping pad is provided on the sliding rod.
[0030] In this embodiment, the discharge port 701 is used to discharge large particulate impurities screened from the microplastics.

[0032] In this embodiment, when it is necessary to discharge the microplastics filtered on the filter membrane holder 4 into the drying chamber 5, the controller starts the drive motor 10 to drive the mounting shaft 11 to rotate, thereby causing the filter membrane holder 4 to flip at a certain angle, so that the microplastics filtered on the filter membrane holder 4 can be put into the drying chamber 5 for drying.
[0033] In a further preferred embodiment of the present invention, two servo motors 12 are fixedly installed on the outer wall of the processing box 1, and two placement shafts 13 are rotatably installed on the processing box 1.

With the cooperation of the connecting pipe 16, the cleaning chamber 2 can be pressurized, thereby accelerating the filtration of microplastics and cleaning solvents.
[0037] In summary, compared with related technologies, this device can perform integrated pretreatment of microplastics, including cleaning, filtering, and drying, and can also screen large particulate impurities in microplastics, effectively improving the pretreatment efficiency of microplastics.
