A calcium and magnesium ion crystallization inhibiting filter mechanism

Abstract

This utility model discloses a calcium and magnesium ion crystallization inhibition filtration mechanism, including a tank. A first filter frame and a second filter frame are arranged inside the tank. A rotating rod passes through the center of the top of each filter frame, and the rotating rod is rotatably connected to the first and second filter frames respectively via bearing seats. Two first support frames and two second support frames are fixedly connected to the surface of the rotating rod. A brush strip is provided on the side wall of the first support frame. This utility model improves the filtration effect by setting two layers of filter frames with gradually decreasing gaps inside the tank. Simultaneously, the brush strips can continuously scrub the outer wall of the filter screen to remove attached crystalline impurities. The extrusion cylinder periodically extrudes the filter screen, causing the filter screen pores to undergo dynamic deformation of expansion and contraction. This not only breaks down the microcrystalline structure through the rubbing of the filter screen fibers, but also uses the water flow during pore expansion to further clean residual impurities inside the filter screen, effectively extending the filter screen's service life and reducing maintenance frequency.

Description

Technical Field

[0001] This utility model relates to the field of water supply system filtration technology, specifically a calcium and magnesium ion crystallization suppression filtration mechanism. Background Technology

[0002] In industrial circulating water systems, domestic water supply pipelines, boiler feedwater, and reverse osmosis water treatment, calcium and magnesium ions in the water are the core cause of scaling problems. When water temperature rises, pH changes, or water becomes concentrated, these ions easily combine with anions such as carbonate and sulfate to form insoluble crystals such as calcium carbonate and magnesium sulfate. These crystals adhere to the inner walls of pipes, the surfaces of heat exchange equipment, or the pores of filter elements, not only reducing the cross-sectional area of ​​the pipe flow and decreasing heat exchange efficiency, but also potentially causing equipment blockage, accelerated corrosion, and other problems, severely shortening the service life of equipment and increasing operation and maintenance costs and safety risks.

[0003] Existing physical filtration solutions mostly use single-layer or multi-layer filters with fixed pore sizes, which can only trap larger crystals that have already formed, but cannot handle the tiny crystals attached to the filter surface. Furthermore, after long-term use, the filter screen is prone to clogging of the pores due to crystal buildup, requiring frequent disassembly and replacement, interrupting the water treatment process, and leading to a continuous decline in filtration efficiency. This makes it difficult to balance filtration precision with the requirements of long-term stable operation. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a calcium and magnesium ion crystallization suppression filtration mechanism, which solves the problem that existing physical filtration solutions proposed in the background art mostly use single-layer or multi-layer filters with fixed pore sizes, which cannot handle the tiny crystals attached to the filter surface. After long-term use, the pores are easily blocked by crystals, requiring frequent disassembly and replacement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a calcium and magnesium ion crystallization inhibition filtration mechanism, comprising a tank, wherein a first filter frame and a second filter frame are provided on the inner side of the tank, and a rotating rod is passed through the center of the top of each of the first and second filter frames. The rotating rod is rotatably connected to the first and second filter frames respectively through bearing seats. Two first support frames and two second support frames are fixedly connected to the surface of the rotating rod. A brush strip is provided on the side wall of the first support frame, and the second support frame is fixedly connected to the extrusion cylinder.

[0006] In this technical solution, the filtration effect is improved by setting two layers of filter frames with gradually decreasing gaps inside the tank. At the same time, the brush strips can scrub the outer wall of the filter screen in real time to remove attached crystalline impurities. The extrusion cylinder periodically squeezes the filter screen, causing the filter screen pores to undergo dynamic deformation of expansion and contraction. This not only breaks down the tiny crystal structure through the rubbing of the filter screen fibers to prevent pore blockage, but also uses the water flow during pore expansion to backwash and further clean residual impurities inside the filter screen, effectively extending the service life of the filter screen and reducing the frequency of maintenance.

[0007] Preferably, the top end of the rotating rod is fixedly connected with several impeller blades in a circumferential array, and the impeller blades are located inside the top opening of the tank.

[0008] Preferably, the two No. 1 support frames are located on the outside of the No. 1 filter frame and the No. 2 filter frame, respectively, and the two No. 2 support frames are located on the inside of the No. 1 filter frame and the No. 2 filter frame, respectively.

[0009] Preferably, the outer side of the tank is provided with two annular tubes, and the surface of the annular tubes is provided with a plurality of nozzles arranged in a circumferential array, the nozzles being located on the inner side of the tank.

[0010] Preferably, the inner wall of the outlet at the bottom of the tank is provided with a water inlet pipe, and the water inlet pipe is connected to a temporary water storage tank on the outside of the tank. The temporary water storage tank is connected to two annular pipes above through a water pumping pipe.

[0011] Preferably, a semiconductor cooling chip is connected through and fixedly to the bottom of the temporary water tank, and the water pump is connected to the water pump at the top of the temporary water tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model improves the filtration effect by setting two layers of filter frames with gradually decreasing gaps inside the tank. At the same time, a rotating rod is set in the center of the inner side of the tank. The rotating rod rotates under the drive of the water flow, which drives the first and second support frames to rotate. The outer brush strip can brush the outer wall of the filter screen in real time to remove attached crystalline impurities, while the inner squeezing cylinder periodically squeezes the filter screen, causing the filter screen pores to undergo dynamic deformation of expansion and contraction. This not only breaks the micro-crystal structure through the rubbing of the filter screen fibers to prevent pore blockage, but also uses the water flow during pore expansion to backwash and further clean the residual impurities inside the filter screen, effectively extending the service life of the filter screen and reducing the frequency of maintenance.

[0013] 2. This utility model introduces part of the filtered water into a temporary storage tank through a water inlet pipe. After being cooled by a semiconductor cooling chip, the water is pumped to a ring pipe and then sprayed directionally onto the surfaces of filter frames No. 1 and No. 2 through nozzles. The low-temperature environment can inhibit the crystallization of calcium and magnesium ions, and the cold water can dissolve some of the fine crystals already attached to the filter screen surface, further reducing the risk of clogging and ensuring the long-term stable operation of the filtration mechanism. Moreover, no additional chemical agents are required, avoiding secondary pollution of the water. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0017] A calcium and magnesium ion crystallization suppression filtration mechanism, see [link / reference] Figures 1 to 4 The system includes a tank body 1, the top of which can be opened for easy disassembly, cleaning, and maintenance. Inside the tank body 1, there are two filter frames: a first filter frame 2 and a second filter frame 3. The top center of both filter frames 2 and 3 is penetrated by a rotating rod 4. The rotating rod 4 is rotatably connected to filter frames 2 and 3 via bearing seats. Two first support frames 401 and two second support frames 402 are fixedly connected to the surface of the rotating rod 4. The side wall of the first support frame 401 is provided with a brush strip 6. The second support frame 402 is fixedly connected to the extrusion cylinder 7. The two first support frames 401 are located on the outside of filter frames 2 and 3, respectively, and the two second support frames 402 are located on the inside of filter frames 2 and 3, respectively.

[0018] In the above technical solution, the water to be treated enters from the top of tank 1 and first contacts filter frame 2. Its larger pores trap larger calcium and magnesium ion crystals and impurities in the water. The remaining water containing tiny crystals continues to permeate downwards to filter frame 3, where it undergoes secondary fine filtration through its smaller pores. Simultaneously, the water flow drives the rotating rod 4 to rotate, which in turn drives support frames 401 and 402 to rotate. Support frame 401 on the outer side causes brush strips 6 to slide against the outer walls of filter frames 2 and 3, brushing off impurities attached to the outer side. Support frame 402 on the inner side causes the squeezing cylinder 7 to periodically squeeze the inner walls of the two filter frames. This squeezing action causes the filter screen to undergo dynamic deformation of expansion and contraction. When the filter fibers rub against each other, they can destroy the attached tiny crystal structures. The instantaneous expansion of the pores creates a reverse water flow, flushing away the fine impurities remaining inside the filter screen, effectively extending the filter screen's lifespan and reducing maintenance frequency.

[0019] Specifically, such as Figure 1 and Figure 2 As shown, two annular pipes 13 are provided on the outer side of the tank body 1. Several nozzles 14 are arranged in a circular array on the surface of the annular pipes 13. The nozzles 14 are located on the inner side of the tank body 1. A water inlet pipe 8 is provided on the inner wall of the outlet at the bottom of the tank body 1. The water inlet pipe 8 is connected to a temporary water storage tank 9 on the outer side of the tank body 1. The temporary water storage tank 9 is connected to the two annular pipes 13 above through a water pumping pipe 12.

[0020] In the above technical solution, a portion of the clean water treated by the double-layer filter frame flows into a temporary water storage tank 9 through a water inlet pipe 8 on the inner wall of the outlet at the bottom of the tank 1. The water in the temporary water storage tank 9, powered by a water pump 11, is then transported through a pumping pipe 12 to two annular pipes 13 on the outside of the tank 1. The annular pipes 13, with nozzles 14 arranged in a circular array and designed for dispersed spraying, direct and evenly spray the water onto the surfaces of the first filter frame 2 and the second filter frame 3, forming a rinsing water flow covering the entire filter screen. The entire process requires no external water source, saving water resources. Furthermore, this rinsing process is synchronized with the water filtration process, without affecting the normal water treatment rhythm, thus improving the continuous operation capability of the equipment.

[0021] Furthermore, such as Figure 2As shown, a semiconductor cooling chip 10 is connected and fixedly connected to the bottom of the temporary water tank 9, and the water pump 11 at the top of the temporary water tank 9 is connected to the water pump 11. After the semiconductor cooling chip 10 is energized, its cooling end cools the water in the temporary water tank 9, keeping the water temperature at a low level. The cooled water is then transported to the annular pipe 13 via the water pump 11 and the water pump 12, and then sprayed onto the filter screen surface through the nozzle 14. The low-temperature water directly acts on the filter screen surface and the surrounding water, reducing the binding rate of calcium and magnesium ions with anions such as carbonate and sulfate, inhibiting the formation of new crystals. On the other hand, the low-temperature environment can increase the solubility of calcium and magnesium ions in the water, causing the small crystals already attached to the filter screen surface to redissolve and detach from the filter screen with the flushing water flow, further reducing the risk of filter screen clogging.

[0022] It is worth noting that, such as Figure 4 As shown, several impeller blades 5 are fixedly connected in a circular array at the top of the rotating rod 4, and the impeller blades 5 are located inside the top opening of the tank body 1. When the water to be treated flows in from the top opening of the tank body 1, the water flow impacts the impeller blades 5 at the top of the rotating rod 4. Under the impact force of the water flow, the impeller blades 5 drive the rotating rod 4 to rotate around the bearing seat, thereby providing power for the movement of the first support frame 401, the second support frame 402, the brush strip 6, and the extrusion cylinder 7. No additional motor or other drive device is required, the structure is simple, the number of equipment failure points is reduced, and the maintenance difficulty is lowered.

[0023] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
