Description

Technical Field

[0001] The present invention belongs to the technical field of sewage microplastic treatment, and specifically provides a device for removing microplastics from polluted water and a method for using the device. Background Art

[0002] Microplastics refer to plastic fragments or particles with a size of less than 5.0 mm. Microplastics degrade very slowly and can persist in the environment, causing persistent pollution. Microplastics in water can cause harm to organisms through ingestion and the food chain. The device and method for preparing microplastic particles have broad application prospects in solving the problem of microplastic pollution in water environments.

[0003] As research on microplastic pollution becomes increasingly in-depth, people have discovered that microplastics have entered almost every link of the Earth's ecosystem, especially the oceans and surface waters, becoming the gathering area of ​​various microplastics and the most important secondary transmission carriers.

[0004] At present, the research on microplastic particles mainly focuses on the detection of microplastics in samples, the ecological migration, transformation and toxicity of microplastics. There are few studies on the technology and equipment for effectively removing microplastic particles in water. At present, it mainly relies on manual sorting, which is time-consuming and labor-intensive and cannot meet the scale demand. Therefore, a device that can effectively remove microplastics from water is developed.

[0005] In the existing sewage microplastic removal device, the first step of the purification process is usually to use a horizontal flow regulating tank for pretreatment, and then pump it to the outside for further disinfection and purification after pretreatment. The horizontal flow regulating tank is often used for pretreatment. It has the advantages of simple structure and low cost, but at the same time, it needs to be equipped with a scraper when driving, and the increase in operation cost is its disadvantage. After initial sedimentation in the water tank, conventional treatment process (coagulation-sedimentation-filtration-disinfection) is adopted for treatment, and the horizontal flow primary sedimentation tank uses a traveling scraper to scrape the dirt settled at the bottom of the tank into the sewage collection tank, and skim the scum on the surface of the tank to the slag collection tank.

[0006] However, in the above-mentioned prior art, after the floating objects on the surface of the primary sedimentation tank are processed, they are not promptly and centrally treated, which will cause secondary pollution to the primary sedimentation tank. In particular, after the floating objects are collected, they are piled up together and cannot be transported out in time. It is still possible that the floating objects are of different sizes and fall into the primary sedimentation tank again in a concentrated manner, which will aggravate the blockage of the sewage pipe.

[0037] like Figure 1-6 As shown, a device for removing microplastics from polluted water bodies of the present invention includes a crushing mechanism 41, a locking and pressing mechanism 42, a lifting and discharging mechanism 43, and a sliding mechanism 44. The crushing mechanism 41 and the locking and pressing mechanism 42 are arranged on the upper part of the sliding mechanism 44, and the lifting and discharging mechanism 43 is arranged on the outer side of the crushing mechanism 41.

[0038] The crushing mechanism 41 includes an upper limiting plate 411 and a lower crushing plate 412. The upper limiting plate 411 is arranged on the upper part of the lower crushing plate 412. The lower crushing plate 412 is slidably connected to the sliding mechanism 44. The two sides of the upper limiting plate 411 are movably connected to the lifting and discharging mechanism 43 and the locking and pressing mechanism 42 respectively.

[0039] The present invention divides the crushing mechanism into two layers, the upper and lower layers, and cooperates the lifting sliding arm 432 with the lifting groove 432b. The lifting sliding arm 432 moves upward relative to the lifting body 431, driving the upper limiting plate 411 to move upward, and a feeding chamber is formed between the upper limiting plate 411 and the lower crushing plate 412. The mobile transfer mechanism 2 sends the salvaged floating objects into the feeding chamber, and cuts and crushes the entering floating objects back and forth between the first crushing slice 4118 and the second crushing slice 4127, so that floating objects of different sizes are changed into a state of uniform size. The size can be adjusted, and the final product is easy to transport. Even if a large amount of floating products after cutting and crushing fall into the primary sedimentation tank, it will not cause blockage of the sewage pipe.

When the first crushing slices 4118 and 4127 are adjusted to completely overlap, the horizontal and longitudinal spacing of the first crushing slice 4118 relative to the second crushing slice 4127 is zero. At this time, the limit missing block 4119 and the limit column 4119b form a matching limit. By moving the first crushing slice 4118, the horizontal and longitudinal spacing with the second crushing slice 4127 is adjusted, so that the width of the floating objects collected by the first crushing slice 4118 and the second crushing slice 4127 is cut.

[0043] The first crushing slice 4118 and the second crushing slice 4127 are both provided with equally spaced horizontal and vertical cutting blades, so that when the first crushing slice 4118 and the second crushing slice 4127 slide relative to each other, floating objects in the gap between the first crushing slice 4118 and the second crushing slice 4127 are cut.

[0044] The locking and pressing mechanism 42 includes a locking base plate 421, a locking pillar 422, and a locking cylinder 423.

At this time, the transmission belt forms a smooth movement, and the mobile carrier connected to its upper end is adjusted to move back and forth in the lateral direction of the second crushing slice on the upper end of the mobile carrier relative to the first crushing slice by starting the forward and reverse rotation and working time of the crushing driving motor, so as to cut and crush the floating objects.

[0048] The locking post 422 is provided with a locking slider 4221 and a locking connecting block 4222 inside the locking post 422.

This design makes the upper limiting plate 411 and the lower crushing plate 412 more closely combined, avoiding the displacement of the lower crushing plate 412 when the first crushing slice 4118 and the second crushing slice 4127 interact with each other, so that the consistency of the cutting width of the crushed floating objects cannot be well guaranteed.

[0049] The bottom of the cylinder arm 424 rotates clockwise, driving the locking connection block 4222 to push the locking slider 4221 downward, wherein the locking protrusion 4223 at the bottom of the locking slider 4221 cooperates with the locking groove 4223b in the upper limiting plate 411 to limit the position of the upper limiting plate 411.
