[0040] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] In order to facilitate understanding of the water treatment and purification device and system provided by the utility model, its application background is first introduced. In order to reduce the waste of heat energy and water resources, condensate, hydrophobic water, and hot network circulating water are usually treated by filtration and desalination processes.

[0042] In related technologies, membrane filters are generally used for condensate, hydrophobic water, and hot network circulating water filtration.

[0043] However, in the aforementioned technologies, the main sources of contamination for condensate, drain water, and circulating water in the heat network are raw water, system leakage, and corrosion. Corrosion generally accounts for over 80% of the pollution, and most of the corrosion products are ferromagnetic substances. The higher the precision of the membrane filter, the greater the operating pressure difference, the higher the iron content requirement for the influent water, the lower the pollution holding capacity, and the shorter the service life. Consequently, these technologies suffer from high operating costs and poor filtration effectiveness.

[0044] In response to the above technical problems, the present invention provides a water treatment and purification device and system, which can improve the water quality, extend the service life of the filter membrane, and reduce operating costs.

[0045] The following combination Figure 1-Figure 4 The utility model is described in detail regarding a water treatment and purification device and system.

[0046] Reference Figure 1 A water treatment and purification device includes a barrel 10, a precision filter 30 and a permanent magnet rod 20; wherein the barrel 10 is provided with a purification chamber 100, a water inlet 101 and a water outlet 102; the precision filter 30 is arranged in the purification chamber 100, for dividing the purification chamber 100 into a magnetic purification area outside the precision filter 30 and a precision filtration area located inside the precision filter 30, the water inlet 101 is connected to the magnetic purification area, the precision filtration area is provided with a water inlet hole 31 and a water outlet hole, the water inlet hole 31 is located at the end of the precision filter 30 away from the water inlet 101, and the water outlet hole is connected to the water outlet 102; the permanent magnet rod 20 is arranged in the magnetic purification area.

[0047] In actual application, incoming water enters the magnetic purification zone of the purification chamber 100 through the water inlet 101. As the water flows through the magnetic purification zone, the permanent magnet rod 20 located in the magnetic purification zone can adsorb ferromagnetic substances in the water. The magnetically purified water enters the precision filter 30 through the water inlet 31. The precision filter 30 can filter non-magnetic impurities in the water. The water filtered by the precision filter 30 enters the water outlet 102 through the water outlet hole and flows out of the device from the water outlet 102. Compared with related technologies, magnetic adsorption can remove ferromagnetic substances in water, extend the service life of the filter membrane 301, and magnetization can slow down the corrosion and scaling of the thermal system. The precision filter 30 can remove non-magnetic particles in the condensed water, thereby improving the water quality of the outlet and reducing operating costs. In addition, the permanent magnet rod 20 can be reused for a long time, generating less waste, and is environmentally friendly.

[0048] The specific structure of the water treatment and purification device will be described in detail below with reference to the accompanying drawings.

[0049] In some optional embodiments, the specific shape, material and size specifications of the cylinder 10 can be flexibly configured according to actual needs.

[0050] In this embodiment, the cylinder 10 is a hollow columnar structure, the water inlet 101 is arranged at one end of the cylinder 10, and the water outlet 102 is arranged at the other end of the cylinder 10, so that after the incoming water enters the cylinder 10, it will flow along the axial direction of the cylinder 10; the precision purifier is arranged along the axial direction of the cylinder 10, thereby forming a magnetic purification area extending along the axial direction of the cylinder 10, and the permanent magnet rod 20 is arranged in the magnetic purification area and arranged along the axial direction of the cylinder 10, so that the permanent magnet rod 20 can fully capture magnetic impurities in the water during the flow of water in the magnetic purification area.

[0051] Multiple precision filters 30 and permanent magnet rods 20 are provided, and the multiple precision filters 30 and permanent magnet rods 20 are evenly spaced. The specific number and arrangement of the precision filters 30 and permanent magnet rods 20 can be flexibly configured according to actual needs, such as the size of the cylinder 10, the size of the precision filters 30 and the permanent magnet rods 20, the magnetic field influence range of the permanent magnet rods 20, and the water purification requirements. However, it is necessary to ensure that the magnetic field range of the multiple permanent magnet rods 20 can cover the entire magnetic purification area to ensure the magnetic purification effect of the water treatment purification device, thereby reducing the influence of magnetic substances on the precision filters 30.

[0052] It is understandable that, according to different practical needs, the precision filter 30 and the permanent magnet rod 20 can be set to different structures.

[0053] In one embodiment of the present invention, referring to Figure 2The permanent magnet rod 20 includes a sleeve 200, a magnetic block 201 and a pad 202; wherein the magnetic block 201 and the pad 202 are alternately filled in the sleeve 200; the magnetic field strength of the magnetic block 201 gradually increases from the water inlet 101 to the water outlet 102, and the pad 202 is made of antimagnetic material.

[0054] Through the above technical solution, the magnetic field strength of the magnetic block 201 gradually increases from the water inlet 101 to the water outlet 102. That is to say, the magnetic field strength of the permanent magnet bar 20 is arranged from weak to strong along the direction of water flow. This is because the concentration of magnetic particles in the water is the highest at the water inlet 101, and the magnetic particles are easily captured by the permanent magnet bar 20. As the water flows, the concentration of magnetic particles gradually decreases. By arranging the magnetic field strength of the permanent magnet bar 20 from weak to strong along the direction of water flow, the uniformity of impurities adsorbed on the permanent magnet bar 20 can be ensured, avoiding the problem of excessive adsorption of local impurities leading to blockage or impurity shedding.

[0055] In one embodiment of the present invention, the sleeve 200 is cylindrical and made of seamless, smooth stainless steel with a wall thickness of less than 1 mm. This helps reduce resistance to water flow and improves corrosion resistance. The magnetic block 201 is cylindrical, with a radially distributed magnetic field. Specifically, the magnetic block 201 can be made of a rare earth permanent magnet material such as neodymium iron boron or samarium cobalt. The magnetic cavity of the rare earth permanent magnet material can enhance the iron removal efficiency and dirt holding capacity of the permanent magnet bar 20. The magnetic field strength of the magnetic block 201 is selected to be 3000-10000 GS. The spacer 202 is a cylindrical spacer 202.

[0056] It is understandable that the sleeve 200, the magnet 201 and the spacer 202 include but are not limited to the shapes and materials listed above. According to different requirements, the sleeve 200, the magnet 201 and the spacer 202 can also be configured into other shapes or materials.

[0057] In one embodiment of the present invention, referring to Figure 3 The precision filter 30 includes a housing 300 and a filter membrane 301 disposed within the housing 300. The filter membrane 301 divides the space within the housing 300 into an outer cavity 302 and an inner cavity 303. The water inlet 31 is connected to the outer cavity 302, and the water outlet is connected to the inner cavity 303. With this arrangement, magnetically purified water enters the outer cavity 302 of the precision filter 30 through the water inlet 31. Under the action of water pressure, the water in the outer cavity 302 passes through the filter membrane 301, enters the inner cavity 303 of the precision filter 30, and flows out through the water outlet. The filter membrane 301 can filter particulate impurities in the water to improve the water quality of the outlet.

[0058] Specifically, the shell 300 is a hollow columnar structure; the filter membrane 301 is a hollow columnar structure and is arranged coaxially with the shell 300. The internal space enclosed by the filter membrane 301 forms the above-mentioned inner cavity 303, and the outer cavity 302 is formed between the filter membrane 301 and the inner wall of the shell 300.

[0059] Depending on actual needs, such as the desired filtration accuracy, filter membrane 301 can be constructed from different materials and structures. Specifically, filter membrane 301 can be arranged as a single-layer structure. When higher filtration accuracy is required, filter membrane 301 can also be arranged as a multi-layer structure for multi-layer filtration. Materials for filter membrane 301 include filter cloth, wound filter material, carbon layer, nano-adsorbent material, ceramic sintered filter material, or metal sintered filter material. When filter membrane 301 is arranged in multiple layers, the materials used for different layers of filter membrane 301 can be the same or different. In this embodiment, filter membrane 301 is arranged in a multi-layer structure, and the filtration accuracy of filter membrane 301 is 1-5 μm.

[0060] In order to ensure the filtration efficiency, in one embodiment of the present invention, Figure 1 and Figure 4 The water treatment and purification device also includes a water inlet distribution structure, which includes a first orifice plate 11 and a distribution chamber 103 arranged in the cylinder 10; the distribution chamber 103 and the purification chamber 100 are separated by the first orifice plate 11, and the water inlet 101 is connected to the distribution chamber 103. The first orifice plate 11 is provided with multiple groups of water distribution holes 110 corresponding to the number of permanent magnet rods 20, and the multiple water distribution holes 110 in each group of water distribution holes 110 are arranged around the permanent magnet rod 20.

[0061] In actual applications, the incoming flow enters the distribution chamber 103 through the water inlet 101 and enters the magnetic purification area of ​​the purification chamber 100 through the water distribution holes 110. Since the multiple water distribution holes 110 in each group of water distribution holes 110 are arranged around the permanent magnet rod 20, the incoming flow can be evenly distributed around each permanent magnet rod 20, ensuring that there is sufficient flow around each permanent magnet rod 20, thereby achieving effective capture of magnetic impurities by the permanent magnet rod 20 and improving the magnetic purification efficiency. In addition, the uniformity of impurities on each permanent magnet rod 20 can also be ensured, avoiding blockage or impurity falling problems caused by excessive impurities on local permanent magnet rods 20.

[0062] In one embodiment of the present invention, the first orifice plate 11 is coaxially arranged at the bottom of the cylinder 10. The first orifice plate 11 and the inner wall of the cylinder 10 can be fixed by welding or connected by bolts or other connecting components. The specific selection can be made according to actual needs.

[0063] In order to improve the water outlet efficiency, in one embodiment of the present invention, the water treatment and purification device also includes a water collecting structure; the water collecting structure includes a second orifice plate 12 and a water collecting chamber 104 arranged in the cylinder 10; the water collecting chamber 104 and the purification chamber 100 are separated by the second orifice plate 12, and the water outlet 102 is connected to the water collecting chamber 104. The second orifice plate 12 is provided with water collecting holes corresponding to the number of precision filters 30, and the water collecting holes are connected to the water outlet holes.

[0064] In actual applications, the water purified by the multiple precision filters 30 flows into the water collecting chamber 104 through the water outlet holes and the water collecting holes, and then is discharged through the water outlet 102, thereby improving the water outlet efficiency.

[0065] Specifically, the second orifice plate 12 is connected to the top of the cylinder 10. The second orifice plate 12 and the cylinder 10 can be connected in a detachable manner or in a non-detachable manner, and the specific selection can be made according to actual needs.

[0066] To facilitate cleaning, maintenance, and replacement of the precision filter 30 and permanent magnet 20, in this embodiment, the barrel 10 has an opening at the end opposite the water inlet 101. The open end of the barrel 10 is detachably connected to a cover 13. Specifically, the cover 13 and barrel 10 can be connected using connecting members such as flanges and bolts. A water collection chamber 104 is formed between the cover 13 and the second orifice plate 12; the second orifice plate 12 is detachably disposed within the barrel 10. The precision filter 30 and permanent magnet 20 are detachable from the second orifice plate 12 at one end and from the first orifice plate 11 at the other end.

[0067] When the permanent magnet rod 20 or the precision filter 30 needs to be cleaned, repaired or replaced, the cover body 13 is removed from the cylinder body 10, and then the second orifice plate 12 is taken out from the cylinder body 10, and the permanent magnet rod 20 or the precision filter 30 can be easily removed from the cylinder body 10 for cleaning, repair or replacement.

[0068] In order to facilitate the disassembly and assembly of the permanent magnet bar 20 or the precision filter 30 , the permanent magnet bar 20 and the precision filter 30 are detachably connected to the second orifice plate 12 .

[0069] In one embodiment of the present invention, the permanent magnet rod 20 is provided with a first threaded end 21 at the end away from the first orifice plate 11, and a first connecting hole is provided on the second orifice plate 12. The first threaded end 21 is passed through the first connecting hole and locked by a nut.

[0070] In one embodiment of the present invention, the precision filter 30 is provided with a second threaded end 32 at the end away from the first orifice plate 11 . The second threaded end 32 is passed through the water collection hole and is locked by a nut.

[0071] With such arrangement, when the second orifice plate 12 is removed, multiple permanent magnet rods 20 and precision filters 30 can be removed from the cylinder 10 at the same time, and then a single permanent magnet rod 20 or precision filter 30 can be removed from the second orifice plate 12 for cleaning, repair or replacement according to actual conditions. When the second orifice plate 12 is installed, multiple permanent magnet rods 20 and precision filters 30 can be installed into the cylinder 10 at the same time, which is conducive to improving the convenience of disassembly and assembly of the permanent magnet rods 20 and precision filters 30.

[0072] In order to facilitate assembly and disassembly, a handle 121 may be provided on the surface of the second orifice plate 12 that opens toward the cylinder 10 .

[0073] Specifically, the water outlet is provided on the second threaded end 32 , so that the second threaded end 32 can be used to connect the precision filter 30 and the second orifice plate 12 , and can also be used to connect the inner cavity 303 of the precision filter 30 and the water collecting cavity 104 .

[0074] In one embodiment of the present invention, a first plug 22 is provided at the end of the permanent magnet bar 20 that is away from the second orifice plate 12. The first plug 22 engages with a first socket provided on the first orifice plate 11. The first plug 22 and the first socket ensure that the permanent magnet bar 20 is positioned and mounted on the second orifice plate 12, thereby improving the stability of the permanent magnet bar 20.

[0075] In one embodiment of the present invention, a second plug 33 is provided at the end of the precision filter 30 that is distal to the second orifice plate 12. The second plug 33 engages with a second socket provided on the first orifice plate 11. The second plug 33 and the second socket ensure that the precision filter 30 is securely positioned and mounted on the second orifice plate 12, improving the stability of the precision filter 30.

[0076] By adopting the above-mentioned technical solution, when the permanent magnet rod 20 or the precision filter 30 needs to be cleaned, repaired or replaced, the cover body 13 is removed from the cylinder body 10, and then the second orifice plate 12 together with multiple permanent magnet rods 20 and precision filter 30 are taken out from the cylinder body 10 at the same time. Then, according to actual conditions, a single permanent magnet rod 20 or precision filter 30 can be removed from the second orifice plate 12 for cleaning, repair or replacement; when installing the second orifice plate 12, multiple permanent magnet rods 20 and precision filter 30 can be installed in the cylinder body 10 at the same time, the first plug 22 is plugged into the first jack, and the second plug 33 is plugged into the second jack, thereby realizing a stable connection between the permanent magnet rod 20 and the precision filter 30 in the cylinder body 10.

[0077] It is understandable that the connection methods between the precision filter 30 and the permanent magnet rod 20 and the first orifice plate 11 and the second orifice plate 12 include but are not limited to the above-mentioned connection methods. Other connection methods that can facilitate the disassembly and assembly of the precision filter 30 and the permanent magnet rod 20 are also applicable.

[0078] In order to further improve the stability of the installation of the permanent magnet rod 20 and the precision filter 30 in the cylinder 10, a fixing ring 14 is fixedly connected in the cylinder 10, and the second orifice plate 12 is attached to the fixing ring 14 and is detachably connected through a connector.

[0079] Specifically, the connecting member may be a bolt.
