At the same time, the controller also starts the first electromagnetic block 29 to generate a dispersed magnetic field. Since the first electromagnetic block 29 is in the magnetic attachment area, The dispersed magnetic field generated by the first electromagnetic block 29 will be filled in the attached magnetic area (the conical box 231 and the magnetic shield box 21 are made of magnetic shielding materials, such as high silicon steel, nickel-iron alloy, etc.), and since the magnetic collecting cover 242 in the attached magnetic component 24 is also located in the attached magnetic area, and the magnetic collecting cover 242 is conical with its large mouth facing the attached magnetic area, it can collect the magnetic field emitted by the first electromagnetic block 29. Because the design of the magnetic collecting cover 242 increases the magnetic field collection area, it is like a funnel, which gathers as much of the dispersed magnetic field in the attached magnetic area as possible, so that the conical magnetic collecting cover 242 can better guide the magnetic field lines, reduce the loss of the magnetic field, improve the magnetic field collection efficiency, and concentrate the collected magnetic field in the narrow mouth direction of the magnetic collecting cover 242; When the magnetic field is concentrated from the large mouth of the magnetic collecting cover 242 to the narrow mouth of the magnetic collecting cover 242 (the narrow mouth direction points to the magnetic hollow ball 241), the magnetic collecting circle 243 with a linear array and decreasing width on the inner wall of the magnetic collecting cover 242 enhances and guides the collected magnetic field. When the magnetic field is transmitted along the magnetic collecting circle 243 to the magnetic hollow ball 241, due to the structure of the decreasing width of the magnetic collecting circle 243, the magnetic field strength gradually increases, which is like a magnetic field amplifier, focusing the originally dispersed and relatively weak magnetic field energy, making the magnetic field reaching the magnetic hollow ball 241 stronger. The enhanced magnetic field is transmitted to the magnetic hollow ball 241 through the magnetic conductive column 244. The multiple grooves opened on the column body of the magnetic conductive column 244 increase the surface area of ​​the magnetic field conduction. It helps the magnetic field to enter the magnetic hollow ball 241 more evenly. After the magnetic hollow ball 241 gathers the magnetic field from the magnetic collecting cover 242 and the magnetic column 244, it transmits the magnetic field to the sewage passing through the conical box 231 in a directional manner. The sewage flows in the conical box 231 and is fully in contact with the magnetic component 24. The magnetic field acts on the impurities in the sewage (the impurities in the sewage mainly include: textile fiber scraps, fine particles produced by cloth processing and other suspended matter, and also contain various organic substances such as dyes and additives remaining in the textile production process), so that the impurities carry magnetic poles (the impurities carry magnetic poles determined by the first electromagnetic block 29), realize the magnetization of the impurities, and thus make the impurities in the sewage magnetic. Under the action of gravity, the magnetized wastewater flows into the adsorption box 251 through the connecting pipe 232; Special explanation is required: During the entire wastewater treatment process, as long as the controller keeps the first electromagnetic block 29 energized, the first electromagnetic block 29 will continue to generate a magnetic field, the magnetic focusing cover 242 will continue to collect the magnetic field, the magnetic focusing circle 243 will continue to enhance and guide the magnetic field, the magnetic column 244 will stably conduct the magnetic field, and the magnetic hollow ball 241 will continue to transmit the magnetic field to the magnetized impurities in the sewage in a directioned manner, and this cycle will be repeated to continuously magnetize the sewage impurities passing through the conical box 231.

[0040] When wastewater flows into the adsorption box 251, since the adsorption box 251 is provided with a liquid level sensor (the liquid detector is a prior art, so it is not shown in the figure), when the capacitive liquid level sensor detects the presence of sewage in the adsorption box 251, it will feedback the information of the presence of liquid to the controller, and the controller will then control the suction pump of the particle box 46 to start, so that the magnetic particles in the box (contrary to the magnetic properties of impurities in the wastewater, the magnetic particles do not have magnetism, and their magnetism comes from the second electromagnetic block 462, and the first electromagnetic block 29 and the magnetic particles in the adsorption box 251 are magnetically charged) and the magnetic particles in the adsorption box 251 are charged. The wastewater in the adsorption box 251 is uniformly sprayed into the wastewater in the adsorption box 251. At the same time, the controller sends an operation signal to the driver 27 and the magnetizer 28, so that the driver 27 (the driver 27 is a low-speed motor) drives the rotating rod 261 of the stirring assembly 26 to rotate. When the rotating rod 261 rotates, it also drives the stirring circle 262, the particle rebound structure 263 and the liquid drainage structure 264 to rotate synchronously.

[0041] Among them, since the driver 27 is a low-speed motor, it can provide a large torque to ensure that the rotating rod 261 rotates smoothly and at a low speed, avoiding many problems in the wastewater treatment process caused by too fast a rotation speed, which affects the magnetic particles from capturing magnetized impurities in the sewage. For example, if the rotation speed is too fast, the magnetic particles move too fast in the sewage. When colliding with the magnetized impurities, the speed is too high, and the magnetic attraction force does not have time to work and they bounce off each other, reducing the capture efficiency. At the same time, if the rotation speed is too fast, the sewage will produce strong turbulence, disrupting the movement trajectory of the magnetic particles and the magnetized impurities that rely on magnetism to approach each other. Smooth and low-speed rotation can effectively avoid these problems and ensure that the magnetic particles efficiently capture the magnetized impurities in the sewage.

[0042] During the rotation of the rotating rod 261, the stirring ring 262, the particle rebound structure 263 and the liquid drainage structure 264 also rotate synchronously with the rotating rod 261, and have different effects respectively: During the rotation of the stirring ring 262: the stirring ring 262 applies stirring force to the sewage and magnetic particles in the adsorption box 251 like a paddle, and the stirring ring 262 continuously cuts the sewage to fully mix the sewage and the magnetic particles. This stirring action increases the contact frequency between the magnetic particles and the magnetized impurities in the sewage, promotes the magnetic particles to capture impurities, and improves the adsorption efficiency. At the same time, the rotation of the stirring ring 262 also causes the sewage to circulate in the adsorption box 251, ensuring that the sewage and particles in the entire adsorption box 251 can be evenly mixed, ensuring the consistency of the adsorption effect; During the rotation of the particle rebound structure 263: during the stirring process of the stirring ring 262, some magnetic particles may gather in a local area of ​​the adsorption box 251, thereby affecting the adsorption effect. Therefore, during the synchronous rotation of the particle rebound structure 263, when the capture cover 2633 in the particle rebound structure 263 contacts the gathered magnetic particles during the rotation, the magnetic particles will be intercepted. Since the elastic block 2632 is made of a material with slight elasticity (such as polyurethane materials, rubber modified materials), the elastic block 2632 will be elastically deformed after being hit by the particles, and then the magnetic particles will be rebounded, changing the movement trajectory of the magnetic particles, so that the magnetic particles are dispersed to different areas of the adsorption box 251, avoiding excessive concentration of magnetic particles, ensuring that the magnetic particles are more evenly distributed in the sewage, and improving the adsorption effect; During the rotation of the liquid drainage structure 264: the flexible multi-groove block 2643 can buffer and guide the flow of sewage, disperse the impact force generated by the stirring circle 262, and convert large water flow fluctuations into smaller, more stable water flows. At the same time, the flexible multi-groove block 2643 can also guide the sewage to flow in a specific direction, so that the sewage forms an orderly circulation in the adsorption box 251, avoiding unstable flow states such as eddy currents, maintaining the stability of the adsorption process, and ensuring that the magnetic particles are fully in contact with and adsorbed by impurities in the sewage.

[0043] Among them, the magnetizer 28 is composed of a frequency converter and an electromagnet, and the frequency converter is connected to a controller and a power supply. The frequency converter can convert fixed-frequency alternating current into alternating current with variable frequency and voltage (the specific conversion adjustment can be customized by the staff in the controller according to the actual situation). The output current contains harmonic components. When this current with harmonics is passed into the electromagnet, the harmonics will cause irregular changes in the magnitude and direction of the current. According to the principle of electromagnetic induction, the intensity and direction of the magnetic field generated by the electromagnet will also change irregularly, thereby generating a tiny chaotic magnetic field. The rotating rod 261 of the stirring assembly 26 drives the stirring ring 262 to stir the sewage and the magnetic particles. The chaotic magnetic field generated by the magnetizer 28 interferes with the originally relatively orderly magnetic field environment. This interference makes the movement trajectory of the magnetic particles more complex and changeable, increases the contact opportunities between the magnetic particles and the magnetized impurities in the sewage, and allows the magnetic particles to approach the impurities from different angles and in different ways, thereby improving the effect of the magnetic particles in capturing the magnetized impurities in the sewage and strengthening the adsorption link in the entire wastewater treatment process.

[0044] It should be noted that the magnetism generated by the magnetizer 28 is lower than the magnetism of impurities and magnetic particles in the sewage.

[0045] Step 2: The controller then issues a command to open the electric drain valve 253 at the bottom of the adsorption box 251 (the electric drain valve 253 is closed when the device is just started. Only when the liquid level sensor detects that there is liquid in the adsorption box 251 and the particle box 46 is in the starting state, the controller will open the electric drain valve 253. In addition, the electric drain valve 253 is always in the open state during the operation of the device. Only when the device stops working, the electric drain valve 253 is closed. The magnetic particles attached to the wastewater and impurities are The wastewater flows into the screening box 31. The arc-shaped top plate 321 in the screening box 31 disperses the wastewater and the magnetic particles to the inclined plates 322 on both sides. The screening holes 323 on the inclined plates 322 allow the wastewater to flow into the bottom of the screening box 31 and enter the next process equipment through the drainage pipe, while the magnetic particles fall into the containing box 33. At this time, the controller controls the electric slider 34 to slide on the inner wall of the screening box 31. The electric slider 34 drives the push block 35 to move back and forth in the containing box 33, pushing the magnetic particles out from the discharge port 311 and allowing them to enter the particle processing mechanism 4.

[0046] Among them, since the interconnecting pipe 422 of the thermal degrader 421 is connected with the discharge port 311, the magnetic particles enter the reaction chamber of the thermal degrader 421, and then the infusion tank 411 of the degradation conveying component 41 stores the degradation agent (the degradation conveying component 41 contains a suction pump by default), and the two-position three-way valve 412 at the output end controls the flow direction of the degradation agent. Under the control of the controller, the two-position three-way valve 412 is opened, and the degradation agent in the infusion tank 411 flows into the one-way sprayer 423 through the transmission pipe 413, and then sprayed into the reaction chamber of the thermal degrader 421, which is used to assist the decomposition of impurities attached to the magnetic particles; Then, the heating system of the thermal degrader 421 is started under the control of the controller, and the particles and degradation agents in the reaction chamber are heated to a specific temperature. Under the combined action of the high temperature environment and the degradation agent, the impurities captured on the magnetic particles undergo a chemical reaction and are decomposed. At the same time, the magnetism attached to the magnetic particles begins to weaken or disappear (the specific reason is explained in the third step), and the generated waste gas is discharged by the gas exhaust system to achieve separation of particles and impurities. After the thermal degradation is completed, the suction device 424 is started to suck the degraded particles through the suction pipe 425 (the degraded magnetic particles are called particles because the magnetism is weakened or disappeared, and they themselves do not have magnetism). The centrifugal pump 43 at the bottom of the base 1 is started to suck the particles sucked by the suction pipe 425. The particles are transported to the heat exchanger 44, where the particles exchange heat with the cooling medium and the temperature is reduced, thereby preventing the high temperature from affecting the subsequent equipment and particle performance. The cooled particles are sucked out of the heat exchanger 44 by the pump body 45 and transported to the storage box of the particle box 46. The second electromagnetic block 462 on the side of the particle box 46 re-magnetizes the particles under the control of the controller (the particles re-magnetized by the second electromagnetic block 462 become magnetic particles again) to restore the magnetic state. When new wastewater needs to be treated, the suction pump of the particle box 46 is started, and the magnetic particles enter the particle spraying pipe 252 through the particle conveying pipe 461 and the three-way pipe 2521, and participate in the process of adsorbing impurities in the sewage again, thereby realizing the recycling of particles.

[0047] Step 3: Explain the problems in Step 1 and Step 2: The first electromagnetic block 29 is installed in the magnetic area of ​​the magnetic shield box 21. When the wastewater treatment starts, the controller sets the current direction of the first electromagnetic block 29 according to the treatment requirements and sends a power-on signal to it. According to Ampere's law (right-hand screw rule), the current direction determines the magnetic pole distribution of the magnetic field generated by the first electromagnetic block 29. For example, the current delivered by the controller makes the magnetic field generated by the first electromagnetic block 29 close to the sewage impurities as the N pole. Then, the impurities in the sewage are magnetized under the action of the magnetic field, and the end of the impurities close to the N pole magnetic field of the first electromagnetic block 29 will show S pole magnetism, which is equivalent to the positive magnetism of this scheme; When the particles complete thermal degradation and cooling and enter the particle box 46, the controller transmits a current in the opposite direction to the first electromagnetic block 29 to the second electromagnetic block 462. According to Ampere's law, the magnetic field generated by the second electromagnetic block 462 has a magnetic pole distribution opposite to that of the first electromagnetic block 29. If the sewage impurities are close to the N pole of the magnetic field of the first electromagnetic block 29, the magnetic field generated by the second electromagnetic block 462 is close to the particle. The S pole, so that the particle close to the S pole of the magnetic field of the second electromagnetic block 462, has an N pole, which is equivalent to the negative magnetism of this solution, so that the particles and sewage impurities have opposite magnetic poles, so as to meet the functional requirements of subsequent adsorption and separation of impurities by magnetism.

[0048] 2): Why the magnetism attached to the magnetic particles begins to weaken or disappear when the magnetic particles are subjected to thermal degradation in the thermal degrader 421: The magnetic particles themselves do not have magnetism, and their magnetism is imparted by the second electromagnetic block 462. When the thermal degrader 421 is performing thermal degradation, on the one hand, the high temperature environment in the thermal degrader 42 intensifies the thermal motion of the microscopic particles inside the particles, disrupting the ordered magnetic moment arrangement originally formed by the magnetization of the second electromagnetic block 462. The directions of the magnetic moments tend to be chaotic and cancel each other out, resulting in weakened magnetism. On the other hand, the chemical reaction between the degradation agent and the impurities attached to the particles will change the chemical composition and structure of the particle surface, forming a covering layer on the particle surface that hinders magnetic conduction, or causing changes in the crystal structure inside the particles, further destroying their magnetism, and ultimately causing the magnetism of the magnetic particles to begin to weaken or disappear during the thermal degradation process.
