Description

Technical Field

[0001] The invention relates to the technical field of water treatment and purification, and more specifically to a multi-media filter. Background Art

[0002] Multi-media filter is a kind of high-efficiency water treatment equipment. It removes suspended matter, particulate matter, colloid and other impurities in water by using two or more filter media to achieve the purpose of purifying water quality. Multi-media filter is also called mechanical filter or filter bed. It uses two or more media as filter layers, such as anthracite, quartz sand or other materials. These media are arranged in layers. Water passes through multiple filter media and uses different molecular sieve effects and chemical adsorption effects of different filter media to gradually remove pollutants in the water so that the water quality reaches specific treatment standards. Common filter materials for multi-media filters include quartz sand, anthracite, activated carbon, magnetite, garnet, porous ceramics, and plastic balls. The different particle sizes and densities of these media form a hierarchical structure of filtration, so that water can enter the filter and undergo multiple filtrations in layers. Multi-media filters have a wide range of applications, mainly including industrial circulating water treatment systems, municipal water supply, Agricultural irrigation water, pure water preparation and commercial pure water preparation, effectively remove impurities in sewage, adsorb oil, silt, suspended matter, harmful substances, etc., so that the water quality meets the requirements of recycling. Multi-media filters have high-efficiency filtering performance and strong adaptability, which can effectively remove different pollutants. Multi-media filters have simple structure, convenient operation, low maintenance cost, and their filter materials are not easy to wear and have a long service life. No chemical agents need to be added during operation, so the operation is stable and reliable, reducing the failure rate and maintenance cost, energy saving and environmental protection, and good scalability. Due to the inconsistent particle size of the media, it is easy to cause blockage and reduce the filtration efficiency. Especially when dealing with a large amount of suspended matter and organic matter, the filtration effect of the multi-media filter may be affected. In order to avoid clogging, the filter needs to be checked and cleaned regularly, which increases the operation and maintenance cost and manpower investment. The medium layer is prone to sticky contamination, especially when dealing with water sources containing organic matter and microorganisms. This not only reduces the filtration effect, but also may cause water quality to deteriorate. The sticky media needs to be replaced regularly. The filtration effect of the multi-media filter is greatly affected by changes in water quality. When the type, concentration or particle size of pollutants in the water source changes, the filtration effect of the filter will be significantly affected. Summary of the invention

[0037] The working principle of the present invention is as follows: the water pump is connected to the filter medium replacement device 1, the water pump is connected to the pump connecting pipe 101 to take water, the water flows through the impeller power generation guide device 102, the impact force of the water flow in the impeller power generation guide device 102 will continuously impact and rotate the rotating impeller 1024, the electric converter 1023 converts the kinetic energy of the water flow into electrical energy and stores it in the power connection board 1022, when the water column passes through the diffuser blade 1028, the diffuser blade 1028 guides and evacuates the water column, and falls from the middle water collection device 103 to the magnetic medium tube 104, the filter medium is placed in the medium release tube 1041, and is between the two mesh frames 1043, the function of the mesh frame 1043 is to position the filter material in the medium release tube 1041 so that the filter material is not washed away by the water flow, and the power connection board The electric energy stored in 1022 is transmitted to the collector valve 105 through the electric line 1025. The collector valve 105 is connected to the electromagnetic coil 1042. The electromagnetic coil 1042 is powered on. After the electromagnetic coil 1042 is powered on, a magnetic field is generated by the electromagnetic induction principle. The electromagnetic coils 1042 are attracted to each other due to the magnetic field, so that the medium tube 1041 is fixed. The filter medium in the electromagnetic coil 1042 is used for a long time, and the filtering effect of the filter medium decreases and the filter medium needs to be replaced. At this time, the water flow in the medium tube 1041 will be blocked by the medium and cannot flow smoothly. The water in the medium tube 1041 accumulates and flows to the middle water collection device 103. Water is constantly accumulated in the middle water collection device 103. The water pressure in the middle water collection device 103 increases, and the pressure squeezes the extrusion block 1039, squeezing the extrusion block 1039. The pressing block 1039 is connected to the conductive sheet 1030, and the conductive sheet 1030 moves away from the double-clamp wire 1037. At this time, the circuit is broken, and the magnetic field of the electromagnetic coil 1042 disappears. There is no attraction between each other. At this time, the medium tube 1041 can be removed in turn to replace the medium. In this process, multiple media are placed in different pipes, and the different media are isolated and independent of each other as a whole. The electromagnetic device is used to convert the kinetic energy of the water flow into electrical energy, and the pipe where the medium is placed is fixed by electromagnetism. When the medium needs to be replaced, the power is turned off, the magnetism is eliminated, and the medium is replaced. There will be no adhesion between the media, and it is easy to replace. When the filter medium of the magnetic medium tube 104 is blocked, the magnetic medium tube 104 cannot have water flow. At this time, there is no water flowing in the diameter tube 202, and the plugging block 2 03 moves upward under the action of the gas spring 205, and the plugging block 203 blocks the pipe mouth of the multiple filtering device 3. When the plugging block 203 moves upward, the air pressure in the water retention straight pipe 206 increases. Due to the siphon principle, the pressure sucks the water in the water retention straight pipe 206 to the water outlet 204, and the backflow rushes to the medium discharge pipe 1041, and the blocked impurities are flushed to the middle pipe 1031. At this time, the middle pipe 1031 has water from the water pump and the backflow water. The pressure in the middle pipe 1031 increases, and the water flow carries the impurities to the discharge pipe 1032, and flushes the sealing door 1033 to the outside. When the impurities in the water obtained by the water pump are large, the one-time filtration is not clean enough, and the filtered water flows into the reflux plugging piece 317 to the steering pipe 305, and finally passes through the water purification square pipe 301.Since there are many impurities in the water and the concentration of the water is relatively high, the water flow pushes the moving magnetic frame 312, and the follower magnetic block 315 and the moving magnetic frame 312 are attracted to each other with a strong magnetic force. The follower magnetic block 315 moves with the moving magnetic frame 312, and the follower magnetic block 315 moves to squeeze the air in the air pump 318. The air in the air pump 318 flows to the expansion air bag 322 through the air transmission tube 321. The expansion air bag 322 is filled with air and begins to expand and extend, so that the water blocking gate 323 moves downward, and the water blocking gate 323 blocks the water purification square pipe 301, and the water flow cannot flow through the water purification square pipe 301. When the follower magnetic block 315 moves, the backflow blocking piece 317 Being pulled by the follower magnetic block 315, the backflow blocking piece 317 no longer blocks the lower pipe opening of the drain valve 306, so that the water flows from the drain valve 306, the drain valve 306 is connected to the upstream pipe 307, the upstream pipe 307 is connected to the receiving block 308, the receiving block 308 is connected to the subsequent filter pipe 309, the subsequent filter pipe 309 is formed integrally with the return pipe 1034, and the water flows to the intermediate pipe 1031 for secondary filtration. If the concentration of the filtered water is still high, the mobile magnetic frame 312 will still move during circulation, and the above operation will be repeated until the water quality is clear. This process is aimed at the problem of sensitive water quality of the filter, and the water can be filtered multiple times to meet the requirements.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
