[0001] This invention belongs to the field of secondary water supply water filtration technology, and particularly relates to a pipe-end water filtration device used in a secondary water supply tank. Background Technology

[0002] Secondary water supply refers to the process by which units or individuals store and pressurize urban public water supply or self-built facility water supply in water tanks and then supply it to users or for their own use through pipelines. During this process, in order to ensure the water quality of secondary water supply, it is necessary to carry out water filtration treatment.

[0003] In the existing technology (patent application CN116920505B, entitled "A Water Filtration Pipe"), the impact of replacing filter media on production efficiency can be reduced. However, in implementing this technical solution, at least the following problems were found in the existing technology:

[0004] During the filtration of tap water between the secondary water supply tank and the pipe end, static filter media are mostly used to filter the flowing water. Over time, this not only requires frequent replacement of the filter screen, but also leads to insufficient water filtration, excessive impurity residue, and affects the use of the water. Summary of the Invention

[0009] The separation assembly includes a servo motor fixed to the top of the protective cover, and a main gear and a main shaft fixed on the output shaft of the servo motor, as well as a secondary gear with a secondary shaft meshing around the main gear. A main spoiler and a secondary spoiler are fixed on the main shaft and the four secondary shafts, respectively.

[0010] The centrifugal assembly includes a partition tube embedded in the filter cylinder and connected to the filter cylinder cover. The bottom of the main shaft and the four auxiliary shafts are respectively fixed with a main filter element and an auxiliary filter element that rotate with the partition tube. A main filter block and an auxiliary filter block are respectively provided on the main filter element and the four auxiliary filter elements.

[0011] Preferably, the separation assembly further includes a main separation net embedded on the upper and lower sides of the main spoiler frame, and a secondary separation net embedded on the upper and lower sides of the secondary spoiler frame, and adopts a diamond design with the same mesh density, and the four sets of secondary spoiler frames are distributed in a symmetrical and staggered manner along the central axis of the main spoiler frame.

[0012] Preferably, the centrifugal assembly further includes a main permeation membrane embedded in the main filter element near the main filter block, and a secondary permeation membrane in the secondary filter element near the secondary filter block. Reverse flow vanes are fixed in the main filter element and the four secondary filter elements, and a turbulence vane is fixed at the bottom of the main filter element to cooperate with the turbulence of the drain pipe.

[0013] Preferably, the main spoiler is larger than the four sets of secondary spoilers, and the main spoiler and secondary spoilers are distributed in a triangular equidistant manner along the central axis of the main rotating shaft and the four secondary rotating shafts.

[0014] Preferably, the upper and lower sides of the partition tube are fitted with sealing frames that are fixedly fitted to the filter cylinder, and the middle area between the filter cylinder and the partition tube is isolated to form a sealed space.

[0015] Preferably, a filter screen is embedded on the side of the filter cylinder cover near the partition pipe, and a large-diameter water inlet is opened at the bottom of the partition pipe.

[0016] Preferably, the main filter element has a main pressure relief port at both ends, and the auxiliary filter element has an auxiliary pressure relief port at both ends, all distributed in a triangular equidistant manner.

[0017] Preferably, the turbulence vanes are arranged in a spiral stepped pattern along the interior of the main filter element and the four auxiliary filter elements, and a liquid level sensor is embedded at the bottom of the turbulence vanes.

[0018] Preferably, a silicone ring is provided between the filter cylinder body and the filter cylinder cover, and lifting lugs are threadedly connected to both sides of the filter cylinder body near the protective cover.

[0019] Preferably, the filter cylinder is fixed with a triangular equidistant bracket on the outer side near the drain pipe, and a lifting cylinder with support feet is longitudinally placed on the bracket.

[0020] The pipe-end water filtration device used in a secondary water supply tank according to the present invention has the following advantages:

[0021] 1. The pipe-end water filtration device used in a secondary water supply tank controls the servo motor to drive the main flow-dispersing frame and the main separation net on the main shaft to rotate linearly through the main gear. The main gear drives the secondary flow-dispersing frame and the secondary separation net on the four secondary shafts to rotate alternately through four sets of secondary gears, so as to perform dynamic flow-dispersing filtration treatment on the secondary water supply source entering the filter cylinder cover, thereby achieving the initial filtration effect of the secondary water supply source.

[0022] 2. The pipe-end water filtration device used in this secondary water supply tank, after preliminary dynamic turbulence separation filtration, supplies secondary water source into the partition pipe through the filter cartridge cover. At the same time, the main rotating shaft and four auxiliary rotating shafts drive the main permeation membrane and main filter block on the main filter element, as well as the auxiliary permeation membrane and auxiliary filter block on the four auxiliary filter elements, to centrifugally filter the secondary water source that reaches the partition pipe.

[0023] Simultaneously, the spiral stepped counter-flow blades apply a counter-impact force to the secondary water supply flowing through the main filter element and four auxiliary filter elements, creating a vortex. This accelerates the filtration process between the secondary water supply and the main permeation membrane and main filter block on the main filter element, as well as the auxiliary permeation membrane and auxiliary filter blocks on the four auxiliary filter elements. It also flushes the water to prevent impurities from clogging the filter and reduces the frequency of cleaning and replacement. Then, the turbulence blades, which rotate synchronously with the main filter element, turbulently discharge the centrifugally filtered secondary water supply to prevent turbulent accumulation and further improve the filtration efficiency and effectiveness of the secondary water supply.

[0024] 3. The pipe-end water filtration equipment used in this secondary water supply tank first implements double insulation and antifreeze measures for the filter cylinder near the partition pipe when the temperature is low. The heater is controlled to conduct heat to the upper and lower heat conduction plates through the heating coil, and the heat storage tank on it stores the heat for a long time. Then, the secondary water supply source in the partition pipe is de-iced and thawed to prevent the secondary water supply source from freezing and affecting its water filtration work, thus ensuring a normal water supply.

Detailed Implementation

[0044] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0045] like Figures 1-17 As shown, a pipe-end water filtration device used in a secondary water supply tank according to the present invention includes a filter cylinder 1, a PLC control panel fixed to the bottom of the filter cylinder 1 by a support, and a filter cylinder cover 2 fixed to the top of the filter cylinder 1 by a locking bolt, and a protective cover 3 fixed to the top of the filter cylinder cover 2.

[0046] Both sides of the filter cylinder cover 2 are connected to water inlet pipes 4, and the bottom of the filter cylinder body 1 is connected to a drain outlet pipe 5. A metering valve is provided on the water inlet pipe 4 and the drain outlet pipe 5. Separation components and centrifugal components for water quality turbulence separation and zone centrifugal separation in the secondary water supply tank are respectively provided in the filter cylinder cover 2 and the filter cylinder body 1. Dynamic turbulence separation filtration treatment is performed on the secondary water supply water entering the filter cylinder cover 2 to achieve the initial filtration effect of the secondary water supply water. Centrifugal filtration is performed on the secondary water supply water reaching the zone pipe 71 to improve the filtration fullness and efficiency of the secondary water supply water.

[0047] A silicone ring 15 is placed between the filter cylinder 1 and the filter cylinder cover 2 to seal the filter cylinder 1 and prevent leakage of secondary water supply. The filter cylinder 1 is threaded with lifting lugs 16 on both sides near the protective cover 3 to facilitate the overall hoisting and movement of the filter cylinder 1. The filter cylinder 1 is fixed with a bracket 17 in a triangular equidistant shape on the outer side near the drain pipe 5. The bracket 17 is vertically mounted with a lifting cylinder 18 with a support foot 19. While providing stable support for the filter cylinder 1, the three lifting cylinders 18 can also be opened and closed to adjust the height of the filter cylinder 1 according to the installation needs.

[0048] like Figures 6-14As shown, the separation assembly includes a servo motor 61 fixed to the top of the protective cover 3, and a main gear 62 and a main rotating shaft 63 fixed on the output shaft of the servo motor 61, as well as a secondary gear 66 meshing with the main gear 62 and having secondary rotating shafts 67 around it. A main flow-deflecting frame 64 and a secondary flow-deflecting frame 68 are fixed on the main rotating shaft 63 and the four secondary rotating shafts 67, respectively. It also includes a main separation net 65 embedded on the upper and lower sides of the main flow-deflecting frame 64. First, the servo motor 61 is controlled to drive the main flow-deflecting frame 64 and the main separation net 65 on the main rotating shaft 63 to rotate linearly through the main gear 62. The main gear 62 drives the secondary flow-deflecting frame 68 and the secondary separation net 69 on the four secondary rotating shafts 67 to rotate alternately through the four sets of secondary gears 66, so as to perform dynamic flow-deflecting separation and filtration treatment on the secondary water supply entering the filter cartridge cover 2, so as to achieve the initial filtration effect of the secondary water supply.

[0049] The secondary separation nets 69 are embedded on the upper and lower sides of the secondary baffle frame 68 and adopt a diamond design with the same mesh density. The four sets of secondary baffle frames 68 are distributed in a symmetrical and staggered manner along the central axis of the main baffle frame 64. The main baffle frame 64 is larger than the four sets of secondary baffle frames 68. The main baffle frame 64 and the secondary baffle frames 68 are distributed in a triangular equidistant manner along the central axis of the main rotating shaft 63 and the four secondary rotating shafts 67, so as to carry out comprehensive and uniform dynamic baffle separation filtration treatment on the secondary water supply source that reaches the filter cartridge cover 2.

[0050] The centrifugal assembly includes a partitioned pipe 71 embedded in the filter cylinder 1 and connected to the filter cylinder cover 2. The secondary water supply from the filter cylinder cover 2, after preliminary dynamic turbulence separation filtration, is fed into the partitioned pipe 71. The bottom of the main rotating shaft 63 and the four auxiliary rotating shafts 67 are respectively fixed with a main filter element 72 and an auxiliary filter element 75 that rotate with the partitioned pipe 71. A main filter block 74 and an auxiliary filter block 77 are respectively provided on the main filter element 72 and the four auxiliary filter elements 75. It also includes a main permeation membrane 73 embedded on the side of the main filter element 72 near the main filter block 74, and an auxiliary permeation membrane 76 on the side of the auxiliary filter element 75 near the auxiliary filter block 77. The main rotating shaft 63 and the four auxiliary rotating shafts 67 drive the main permeation membrane 73 and the main filter block 74 on the main filter element 72, and the auxiliary permeation membrane 76 and the auxiliary filter block 77 on the four auxiliary filter elements 75 to perform centrifugal filtration on the secondary water supply that reaches the partitioned pipe 71.

[0051] A counterflow vane 78 is fixed inside the main filter element 72 and four auxiliary filter elements 75. A turbulence vane 79, which works in conjunction with the drain pipe 5, is fixed at the bottom of the main filter element 72. The main filter element 72 and the four auxiliary filter elements 75 synchronously drive the counterflow vane 78, which adopts a spiral stepped design, to rotate linearly. This applies a counter-impact force to the secondary water supply flowing through the main filter element 72 and the four auxiliary filter elements 75, causing it to form a vortex. This accelerates the filtration process between the secondary water supply and the main permeation membrane 73 and the main filter block 74 on the main filter element 72, as well as the auxiliary permeation membrane 76 and the auxiliary filter block 77 on the four auxiliary filter elements 75. It also flushes the water supply to prevent impurities from clogging the filter and reduces the frequency of cleaning and replacement. The turbulence vane 79, which rotates synchronously with the main filter element 72, then turbulently discharges the centrifugally filtered secondary water supply to prevent turbulent accumulation and further improve the filtration efficiency and effectiveness of the secondary water supply.

[0052] Both the upper and lower sides of the partition pipe 71 are fitted with sealing brackets 9 that are fixedly fitted to the filter cylinder 1, thus isolating the middle area between the filter cylinder 1 and the partition pipe 71 to form a sealed space. This improves the stability of the partition pipe 71 and also facilitates the subsequent heat distribution within the sealed space, thus insulating the partition pipe 71. A filter screen plate 10 is embedded on the side of the filter cylinder cover 2 near the partition pipe 71, so that the secondary water supply source in the filter cylinder cover 2 can be coarsely filtered by the filter screen plate 10 and then divided into partitions to reach the partition pipe 71. Inside the partition pipe 71, a large-diameter water guide 11 is provided at the bottom of the partition pipe 71 to quickly discharge the secondary water supply source that has completed centrifugal filtration through the partition pipe 71. The main filter element 72 has a main pressure relief port 12 at both ends, and the auxiliary filter element 75 has an auxiliary pressure relief port 13 at both ends. They are all distributed in a triangular equidistant state to relieve pressure on the main filter element 72 and the four auxiliary filter elements 75 to prevent excessive water pressure inside from deforming the main filter element 72 and the four auxiliary filter elements 75.

[0053] The counterflow vanes 78 are arranged in a spiral stepped pattern along the interior of the main filter element 72 and the four auxiliary filter elements 75. They form a vortex in the spiral that the secondary water supply source is in a centrifugal filtration state as it flows through the main filter element 72 and the four auxiliary filter elements 75, which accelerates the filtration process of the water supply source through the main filter element 72 and the four auxiliary filter elements 75. They also perform counter-impact cleaning on the main filter element 72 and the four auxiliary filter elements 75, reducing the frequency of replacement and cleaning. In addition, a liquid level sensor 14 is embedded at the bottom of the turbulence vanes 79 to monitor the water level of the secondary water supply source after filtration at the bottom of the filter cylinder 1 in real time.

[0054] like Figures 15-17As shown, in low temperatures, especially in northern regions, the secondary water supply source freezes, affecting water filtration and compromising the supply of secondary water. It lacks de-icing and thawing capabilities. The filter cylinder 1 is equipped with a de-icing component for use with the partition pipe 71. This component includes an insulation layer 81 on the outside of the filter cylinder 1 and an insulation cover 82 covering the filter cylinder 1 near the insulation layer 81. In low temperatures, the insulation layer 81 and the insulation cover 82 provide double insulation and anti-freezing measures for the filter cylinder 1 near the partition pipe 71. A heating element is fixed to the outside of the insulation cover 82. The heater 83 has heating coils 84 fitted onto the partition pipe 71 on both its upper and lower sides and fixed to the filter cylinder 1. Heat conducting plates 85 fitted onto the partition pipe 71 are fixed onto both its upper and lower sides and arrayed on the inner side of the heat conducting plates 85. The heater 83 conducts heat to the upper and lower sets of heat conducting plates 85 through the heating coils 84, and the heat is stored in the heat storage tanks 86 for a long time. This process is used to defrost the secondary water supply in the partition pipe 71 to prevent the secondary water supply from freezing and affecting its water filtration, thus ensuring a normal water supply.

[0055] The working principle of a pipe-end water filtration device used in a secondary water supply tank is as follows: First, the water in the secondary water supply tank is discharged into the filter cylinder cover 2 through two inlet pipes 4. Then, the servo motor 61 is turned on and drives the main flow-dispersing frame 64 and the main separation net 65 on the main shaft 63 to rotate linearly through the main gear 62. The secondary water supply source entering the filter cylinder cover 2 is separated by flow disturbance. At the same time, the main gear 62 drives the secondary shafts 67 on the four sets of secondary gears 66 to rotate synchronously. The four secondary shafts 67 drive the four sets of secondary flow-dispersing frames 68 and secondary separation nets 69 to separate the secondary water supply source entering the filter cylinder cover 2 in an interleaved manner. Together with the main flow-dispersing frame 64 and the main separation net 65, the flow disturbance is dynamically dispersed from the center to the outside. The secondary water supply source that has been pre-filtered in the filter cylinder cover 2 is then fed into the partition pipe 71 through the filter screen plate 10.

[0056] While the partition pipe 71 processes the pre-filtered secondary water supply in its respective partitions, the main rotating shaft 63 and four auxiliary rotating shafts 67 drive the main filter element 72 and four auxiliary filter elements 75 to rotate within the partition pipe 71, centrifugally filtering the secondary water supply flowing through each partition. During this process, the main filter element 72 drives the main osmotic membrane 73 and the main filter block 74 to perform osmotic adsorption filtration on the secondary water supply flowing through each partition, and the four auxiliary filter elements 75 drive the auxiliary osmotic membrane 76 and the auxiliary filter block 77 to perform similar osmotic adsorption filtration on the secondary water supply flowing through each partition. Simultaneously, the main filter element 72 and the four auxiliary filter elements... The counter-flow blades 78, which rotate synchronously with the core 75, form a spiral vortex on the secondary water supply flowing through the partition, and accelerate the flow of the secondary water supply through the main filter element 72 and the four auxiliary filter elements 75. While accelerating the filtration process, the secondary water supply also generates a reverse impact force on the main filter element 72 and the four auxiliary filter elements 75, flushing away the impurities accumulated on their surfaces. The secondary water supply after centrifugal filtration is discharged to the bottom of the filter cylinder 1 through the large-diameter water guide 11 at the bottom of the partition pipe 71. Then, the turbulence blades 79, which rotate synchronously with the main filter element 72, turbulently discharge the secondary water supply that has gathered at the bottom of the filter cylinder 1 through the drain pipe 5.

[0057] When the weather temperature is low, the insulation layer 81 and the insulation cover 82 first provide double insulation to the outside of the filter cylinder 1 where the partition pipe 71 is located. Then, the filter cylinder 1 forms triple insulation for the partition pipe 71, which reduces the impact of the low temperature outside on the secondary water supply source in the partition pipe 71. The heater 83 is turned on as needed and the heat is transferred to the heat conduction plate 85 area through the heating coil 84. The heat is temporarily stored in the heat storage tank 86 on it. Then, the heat from the heating coil 84 and the heat conduction plate 85 area is transferred to the partition pipe 71 to defrost the secondary water supply source and ensure the filtration and supply of the secondary water supply source in the partition pipe 71.

[0058] It should be noted that the specific models and specifications of the servo motor 61, heater 83, lifting cylinder 18, as well as various valves and sensors, need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0059] The power supply circuits for the servo motor 61, heater 83, lifting cylinder 18, and various valves and sensors are clear to those skilled in the art and will not be described in detail here.

[0060] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present invention.
