This invention discloses a high-speed, ultra-wide reverse coating apparatus, comprising a frame with a doctor blade frame on one side; an anilox roller assembly, a pressure roller moving device, a gap adjustment device, a glue receiving tray assembly, and a guide roller assembly are mounted on the frame; the pressure roller moving device is equipped with a guide roller assembly A, a traction roller assembly, a traction pressure roller assembly, a traction gap adjustment device, and an adjusting roller assembly, and is located above the anilox roller assembly; the gap adjustment device controls the gap between the traction roller assembly and the anilox roller assembly; the adjusting roller assembly is located on one side of the anilox roller assembly and adjusts the angle at which the film enters the anilox roller by moving it up and down; a closed doctor blade assembly is mounted on the doctor blade frame, which can rotate to fit onto the anilox roller assembly, transferring the glue onto the anilox roller assembly, and then transferring it onto the film through the anilox roller assembly; the rotation direction of the anilox roller is opposite to the forward direction of the film, thereby achieving reverse coating.

This invention relates to a multi-energy coupled self-driven wastewater treatment and heat recovery synergistic system. It includes a wastewater treatment component, a heat recovery component, and a thermoelectric module. The wastewater treatment component comprises a flocculation chamber, a wastewater treatment chamber, and a flocculated particle collection chamber. The sidewall of the flocculation chamber is equipped with a flexible diaphragm switch driven by fluid pressure difference, enabling adaptive and precise dosing of flocculant. The flocculated particle collection chamber is equipped with a flocculated particle capture plate triggered by particle gravity torque, achieving self-triggered solid-liquid separation. The heat recovery component suspends multiple phase change heat storage rods via elastic ropes. The front end of each phase change heat storage rod has a balance ball controlled by a positive arc temperature-sensing piezoelectric spring signal, which, together with the elastic ropes, excites the phase change heat storage rod to generate multi-degree-of-freedom oscillation, enhancing heat transfer. The phase change heat storage rods have a built-in thermoelectric module that converts the temperature difference energy and expansion mechanical energy of the phase change process into electrical energy, providing self-powered operation for the system. This achieves integrated, low-energy-consumption operation.

The application discloses a preparation method of amino-modified magnetic microspheres, which comprises the following steps: modifying the surface of magnetic nanoparticles to obtain magnetic microspheres with double bonds on the surface; performing a polymerization reaction on the surface of the magnetic microspheres to form core-shell magnetic beads with a surface polymer; and performing an amino-modification treatment on the core-shell magnetic beads to form amino-modified magnetic microspheres. The magnetic microspheres have strong magnetism, uniform particle size distribution, regular morphology, and small batch difference, and the sensitivity of magnetic bead extraction is greatly improved.
