Description

Technical Field

[0001] This invention relates to the field of microplastic removal technology, specifically to a microplastic removal device for wastewater. Background Technology

[0002] Microplastics are plastics smaller than 5 mm in size, widely found in the atmosphere, soil, oceans, freshwater, and even in sediments of Arctic freshwater lakes. Microplastics may originate from the degradation and weathering of larger plastic products (secondary microplastics); or they may be directly manufactured in industrial processes (primary microplastics), such as microbeads used in facial scrubs. Due to their small size, microplastics easily accumulate in organisms and gradually accumulate along the food chain. The sludge transport and disposal problems arising from existing microplastic flocculation and sedimentation processes are difficult to solve. In most chemical precipitation operations, a large amount of sludge is generated, often reaching 0.5% of the treated water volume, and the treatment of this chemical sludge is quite challenging.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-12 This invention provides a technical solution: a microplastic removal device for wastewater, comprising a base plate 18, a mounting base 21 fixedly connected to the top of the base plate 18, screws 6 installed inside the mounting base 21, a stirring container 2 installed on the inner side of the mounting base 21 by the screws 6, a stirring mechanism 7 provided inside the stirring container 2, a first water pipe 15 fixedly connected inside the stirring container 2, a filter box 3 installed on the top of the base plate 18, four first L-shaped fixing plates 16 symmetrically fixedly connected to the outer side of the filter box 3, the first L-shaped fixing plates 16 being bolted to the base plate 18, and one end of the first water pipe 15 being fixedly connected to the filter box 3. The filter box 3 is equipped with a filter mechanism 9 inside. The filter box 3 is slidably connected with a sealing cover 4. The mixing container 2 is fixedly connected with a second water pipe 19. A water pump 5 is installed on the top of the bottom plate 18. The output end of the water pump 5 is fixedly connected to the second water pipe 19. The input end of the water pump 5 is fixedly connected to a water pumping pipe. The sewage that needs to be treated is pumped out by the water pump 5 through the water pumping pipe and pumped into the second water pipe 19 and into the mixing container 2 for mixing. A magnetic powder adding box 1 is bolted to the top of the mixing container 2. A adding mechanism 8 that cooperates with the mixing container 2 is provided on one side of the magnetic powder adding box 1.

[0029] The stirring mechanism 7 includes a first motor 72, which is installed inside the stirring container 2. The output end of the first motor 72 is fixedly connected to a stirring blade 73. An oil suction pump 71 is bolted to the top of the stirring container 2. The output end of the oil suction pump 71 is connected to the stirring container 2 through a pipe. The input end of the oil suction pump 71 is fixedly connected to an inlet pipe. The oil suction pump 71 draws in external wastewater treatment oil and puts it into the stirring container 2 for mixing, thereby improving work efficiency.

[0030] The oil suction pump 71 is fixedly connected to a second L-shaped fixing plate 17 on one side. The second L-shaped fixing plate 17 is connected to the mixing container 2 by bolts. The position of the oil suction pump 71 is further stabilized by the second L-shaped fixing plate 17, which improves the working stability.

[0031] The addition mechanism 8 includes a quantitative magnetic powder disc 82. A rotating rod 12 is rotatably connected inside the magnetic powder addition box 1. The quantitative magnetic powder disc 82 is fixedly connected to the outside of the rotating rod 12. The quantitative magnetic powder disc 82 is rotatably connected to the magnetic powder addition box 1. Two feeding troughs 10 that cooperate with the stirring container 2 are symmetrically opened on the outside of the quantitative magnetic powder disc 82. A rotating disc 81 is fixedly connected to the outside of the rotating rod 12. An installation plate 85 is fixedly connected to one side of the magnetic powder addition box 1, and the rotating rod 12 is rotatably connected to the installation plate 85. The rotating disc 81 is rotatably connected to the installation plate 85. The quantitative magnetic powder disc 82 is rotatably connected to the installation plate 85. A second motor 11 is provided inside the magnetic powder addition box 1. The output end of the second motor 11 is fixedly connected to the rotating rod 12. The output end of the second motor 11 drives the rotating rod 12 and the quantitative magnetic powder disc 82 to rotate. The feeding troughs 10 of the quantitative magnetic powder disc 82 convey and add magnetic powder, thereby improving the processing efficiency.

[0032] One side of the mounting plate 85 is rotatably connected to a swing rod 86 via a rotating shaft. The swing rod 86 has a through groove 84 inside. One side of the rotating disc 81 is fixedly connected to a fixing rod 83 that cooperates with the through groove 84. One side of the swing rod 86 is fixedly connected to a square fixing plate 14. The square fixing plate 14 is fixedly connected to a stirring rod 13 inside. The square fixing plate 14 drives the stirring rod 13 to move. The stirring rod 13 stirs the magnetic powder and flattens the pile of magnetic powder after each scooping to ensure that the next feeding trough 10 can scoop an equal amount of magnetic powder.

[0033] The filtration mechanism 9 includes a filter element 91. The filter box 3 has four slots equidistantly arranged inside. Each of the four slots is equipped with a filter element 91. The filter element 91 is equipped with multiple magnet blocks 92. The magnet blocks 92 are placed in the slots to adsorb the flocs formed by microplastics and magnetic powder in the sewage.

[0034] A valve 22 is installed on the outside of the first water pipe 15, and the valve 22 controls the flow of water through the first water pipe 15.

[0035] Among them, the first water pipe 15 is in a U-shaped structure. The first water pipe 15 is made into a U shape. First, it is closed to make the liquid fill the water pipe. The water outlet of the first water pipe 15 is lower than the water surface of the upper container. The height from the highest point of the pipe to the water surface of the upper container is lower than the height of the water column supported by the atmospheric pressure. After opening, the water source continuously flows into the filter box 3 for filtration treatment by using the siphon principle.

[0036] Among them, a control switch power supply 20 is installed on the top of the bottom plate 18. The water pump 5, the oil suction pump 71, the first motor 72 and the second motor 11 are respectively electrically connected to the control switch power supply 20, which is convenient for centralized control and processing of the device through the control switch power supply 20, and improves the stability and safety of the device during operation.

[0037] Specifically, when in use, the device is powered on through an external power supply. The water pump 5 is started through the control switch power supply 20. The water pump 5 pumps the external sewage into the second water pipe 19 and inputs it into the mixing container 2 through the second water pipe 19. The first motor 72 is started through the control switch power supply 20. The output end of the first motor 72 drives the stirring fan blade 73 to rotate. The stirring fan blade 73 stirs the inside of the mixing container 2. At the same time, the oil suction pump 71 is started. The oil suction pump 71 pumps the external plant liquid into the mixing container 2 and mixes it with the sewage in the mixing container 2. At the same time, the second motor 11 is started through the control switch power supply 20. The output end of the second motor 11 drives the rotating rod 12 to rotate. The rotating rod 12 drives the rotating disk 81 and the quantitative magnetic powder disk 82 to rotate. When rotating, the feeding groove 10 opened on the quantitative magnetic powder disk 82 scoops out magnetic powder from the magnetic powder pile and adds it to the stirring component. When one feeding groove 10 moves to the top, the other feeding groove 10 just scoops out magnetic powder. In this way, magnetic powder is added cyclically, and the inside of the mixing container 2 is mixed. At the same time, the second motor 11 drives the rotating disk 81 to rotate. The fixed rod 83 on one side of the rotating disk 81 reciprocates to drive the swing rod​​In the description of this invention, it should be understood that the terms "coaxial," "bottom," "one end," "top," "middle," "other end," "upper," "side," "top," "inner," "front," "center," "both ends," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
