A magnetic-generated electricity-based polymer water-based paint stirring device, which relates to the technical field of polymer water-based paint, includes a fixing table, the inner wall of the middle part of the fixing table is fixedly connected with two mutually symmetrical magnetic sheets, and the inner wall of the fixing table is close to A magnetic ring 1 is fixedly connected to the top of the magnetic sheet, and a magnetic ring 2 is fixedly connected to the top of the inner wall of the fixing table and close to the magnetic ring 1. The magnetic-generated electricity-based polymer water-based paint stirring device is used in conjunction with a closed coil and a magnetic sheet. Since the opposite surfaces of the two symmetrical magnetic sheets have opposite magnetic properties, a magnetic field line will be generated between the two magnetic sheets. When the output shaft rotates, it drives the closed coil in the middle to continuously cut the magnetic field lines between the magnetic sheets. According to the principle of magnetic generation, current will be generated in the closed coil, so as to achieve the effect of self-generating, using the self-rotation of the output shaft, Convert kinetic energy into electrical energy, effectively saving power resources and saving production costs.

A sewage pipe fixing device based on the principle of capacitance change

A sewage pipe fixing device based on the principle of capacitance change, which relates to the technical field of sewage treatment, includes a base, an arc-shaped groove is opened in the middle of the base, and the inner bottom wall on the left side of the arc-shaped groove is fixedly connected with a spring one and a spring one The top of the spring is fixedly connected with a dielectric plate that runs through and extends to the top of the base, the inner bottom wall on the right side of the arc groove is fixedly connected with a spring two, and the top of the spring two is fixedly connected with a piston rod that runs through and extends to the top of the base. The sewage pipeline fixing device based on the principle of capacitance change, through the cooperation of the impeller and the magnetic push device, when the pipeline is blocked, the flow of sewage will stop, and the impeller will stop rotating at this time, resulting in the disconnection of the entire power supply. When the warning light is off, the maintenance personnel can judge the position of the pipeline blockage according to the state of the warning light. The position of the pipeline blockage is between the fixing device with the warning light on and the fixing device with the warning light off, thus achieving the effect of easy detection of pipeline blockage.

An anti-loosening exhaust gas treatment device based on the principle of magnetoelectricity

An anti-loosening exhaust gas treatment device based on the principle of magnetoelectricity, which relates to the technical field of air pollution control, includes a housing, the middle of the housing is fixedly connected with a three-phase catalytic converter, and the inner walls at both ends of the housing are fixedly connected with two For mutually symmetrical magnetic rings, electromagnets are fixedly connected to the inner walls of both ends of the casing, and evenly distributed springs are fixedly connected to the outer sides of the casing. The anti-loose exhaust gas treatment device based on the principle of magnetoelectricity is used in conjunction with the limit block and the limit slot. When in use, the exhaust gas will drive the closed coil in the impeller to continuously cut the magnetic induction line of the magnetic ring, which is generated according to the principle of magnetoelectricity. Current, and the current is sent to the electromagnet to make the electromagnet generate magnetism, and then according to the principle of repulsion of the same sex, the limit block moves to the outside and engages with the limit slot, thereby achieving the effect of preventing the fixing screw from loosening. Effectively prevent exhaust gas leakage and ensure the fastening of the exhaust processor.
