Description

Technical Field

[0001] This invention belongs to the technical field of descaling equipment, specifically relating to a scale prevention, descaling, and corrosion prevention device and its usage method. Background Technology

[0002] Descaling equipment is a specialized instrument that uses physical methods to treat water. It alters the structure of water molecules through technologies such as electromagnetic fields to achieve functions such as scale prevention, scale removal, sterilization, algae control, and corrosion prevention. It is widely used in industrial cooling systems, central air conditioning, boilers, and other circulating water treatment applications. This equipment utilizes permanent magnet systems, electromagnetic descaling, and variable frequency descaling technologies, using alternating magnetic fields to induce calcium and magnesium ions to form suspended crystals.

[0003] Existing descaling equipment, while performing scale prevention and removal operations on water, cannot remove impurities such as organic matter, causing these impurities to precipitate on the electrodes. This affects the normal water treatment capabilities of the descaling equipment electrodes. Furthermore, the activated carbon filter media used in existing technologies for adsorbing and filtering impurities and suspended crystals becomes clogged after sufficient adsorption and filtration, and cannot be automatically replaced. This requires manual intervention to stop the machine for replacement, significantly impacting the water treatment efficiency of the descaling equipment. Therefore, designing a scale prevention, descaling, and corrosion prevention device and its application method to address these issues is a problem we currently need to solve. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a scale prevention, scale removal, and corrosion prevention device and its usage method.

[0005] To achieve the above objectives, the present invention provides a scale prevention, descaling, and corrosion prevention device and its usage method, comprising a housing, sealing flanges fixedly installed on the outer walls at both ends of the housing, a descaling unit fixedly installed on the outer wall of the housing, and electrodes fixedly installed on the inner wall of the housing, the outer contour of the electrodes being adapted to the inner contour of the housing;

[0006] A cleaning component, which is connected to the housing and the electrode;

[0007] Replacement component, which is connected to the housing and cleaning component;

[0008] A filter element, which is connected to the cleaning assembly and the replacement assembly.

[0009] In the above technical solution, the cleaning component further includes a cleaning ring that abuts against the inner wall of the electrode, a connecting rod that is fixedly connected to the outer wall of the cleaning ring, a connecting piece that is fixedly connected to the end of the connecting rod away from the cleaning ring, a connecting piece that is fixedly installed on the outer wall of the connecting piece, and a sliding groove that is opened inside the housing, and the connecting piece that is slidably connected inside the sliding groove.

[0010] In the above technical solution, a sealing sleeve is slidably connected to the end of the connecting piece away from the connecting member. The sealing sleeve is slidably connected inside the housing. A first spring is fixedly installed inside the sealing sleeve. A retaining ring is fixedly installed at the end of the first spring away from the sealing sleeve. The retaining ring is fixedly installed on the inner wall of one end of the housing.

[0011] In the above technical solution, the replacement component further includes a box body and a discharge sleeve fixedly installed on the outer wall of the housing. The box body is located above the discharge sleeve. A water pipe is fixedly connected between the box body and the housing. A sealing valve is fixedly installed inside the water pipe. A flow guide hole is opened inside the box body. A box cover is provided on the side of the box body away from the water pipe. A bolt is inserted into the inside of the box cover. The bolt is threaded into the inside of the box body.

[0012] In the above technical solution, a protective sleeve is fixedly installed on the outer wall of the discharge sleeve, a second spring is fixedly installed inside the protective sleeve, a connecting plate is fixedly installed at the bottom of the second spring, a sealing plate is fixedly installed on the outer wall of the connecting plate, the sealing plate is slidably connected inside the discharge sleeve, and two hinges are rotatably connected to one side of the sealing plate, the two hinges being inserted into the inside of the discharge sleeve.

[0013] In the above technical solution, the filter element further includes a first semi-circular ring and a second semi-circular ring, which are interlocked with each other. An installation ring is provided inside the first and second semi-circular rings, and activated carbon filter material is fixedly installed inside the installation ring. The number of filter elements is set to multiple, one of which is located inside the connector, and the remaining filter elements are inserted into the inside of the box. A partition plate is provided on the side of the multiple filter elements inside the box that is close to the water pipe.

[0014] In the above technical solution, the connector is rotatably connected to a first ball bearing, and the sealing sleeve is rotatably connected to a second ball bearing.

[0015] A method for using a scale prevention, descaling, and corrosion prevention device includes the following steps:

[0016] S1. Connect the equipment to the pipe that needs to be prevented and descaled via a sealing flange, test the sealing performance of the equipment connected to the pipe, and test run the equipment;

[0017] S2. Start the equipment and open the pipeline valves so that the equipment electrodes form a magnetic field that causes calcium and magnesium ions in the passing water to form suspended crystals;

[0018] S3. Then the water will carry suspended crystals and impurities through the filter, which will adsorb and filter the suspended crystals and impurities in the water.

[0019] S4. As the amount of suspended crystals and impurities adsorbed and filtered on the filter element increases, the filter element will gradually become clogged, which increases the resistance of water flowing through the filter element. This causes the water to push the filter element, thereby driving the cleaning component and the replacement component to work. The cleaning component cleans the impurities adhering to the electrodes, and the replacement component replaces the clogged filter element.

[0020] S5. After the filter element is replaced, the resistance of the filter element to water flow decreases, the cleaning component drives the filter element to reset, and the process ends.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] By setting a replacement component, the filter element can be automatically replaced after it becomes clogged and pushed by water, thus avoiding affecting the water flow and the adsorption and filtration effect on impurities and floating crystals.

[0023] The cleaning component automatically cleans the electrodes after the filter becomes clogged and is pushed by water, preventing impurities from adhering to the electrodes and affecting the water treatment effect.

[0024] By installing filter elements, impurities in the water and suspended crystals formed by high-frequency electromagnetic fields can be adsorbed and filtered, reducing impurities in the water, removing organic matter from residual microorganisms in the water, further inhibiting the growth of microorganisms, and preventing the water from becoming foul-smelling.

[0033] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 7 The scale prevention, descaling, and corrosion prevention equipment and its usage method are shown. The equipment includes a housing 1, with sealing flanges 2 fixedly installed on the outer walls at both ends of the housing 1; a descaling unit 3 fixedly installed on the outer wall of the housing 1; and electrodes 4 fixedly installed on the inner wall of the housing 1, the outer contour of which is adapted to the inner contour of the housing 1; a cleaning component connected to the housing 1 and the electrodes 4; a replacement component connected to the housing 1 and the cleaning component; and a filter element connected to both the cleaning component and the replacement component.

[0035] The descaling unit 3 and the electrode 4 are electrically connected by an insulated wire (not shown). The electrode 4 is powered, which causes it to generate a high-frequency electromagnetic field. The water passing through the electrode 4 resonates under the influence of the high-frequency electromagnetic field, causing calcium and magnesium ions in the water to form suspended crystals that prevent scale formation on the inner walls of pipes and equipment. This achieves the effect of preventing scale formation inside pipes and equipment. At the same time, the high-frequency electromagnetic field destroys the living environment of microorganisms in the water, kills bacteria and algae, and prevents excessive microorganisms in the water from causing foul odors.

[0036] The cleaning assembly includes a cleaning ring 5 that rests against the inner wall of the electrode 4. A connecting rod 6 is fixedly connected to the outer wall of the cleaning ring 5. A connector 7 is fixedly connected to the end of the connecting rod 6 away from the cleaning ring 5. A connecting piece 8 is fixedly installed on the outer wall of the connector 7. A sliding groove 9 is provided inside the housing 1. The connecting piece 8 is slidably connected inside the sliding groove 9. A sealing sleeve 10 is slidably connected to the end of the connecting piece 8 away from the connector 7. The sealing sleeve 10 is slidably connected inside the housing 1. A first spring 11 is fixedly installed inside the sealing sleeve 10. A retaining ring 12 is fixedly installed to the end of the first spring 11 away from the sealing sleeve 10. The retaining ring 12 is fixedly installed on the inner wall of one end of the housing 1. A first ball bearing 29 is rotatably connected inside the connector 7. A second ball bearing 30 is rotatably connected inside the sealing sleeve 10.

[0037] The cleaning component is used in conjunction with the filter to clean impurities adhering to the electrode 4.

[0038] Specifically, when the water passing through electrode 4 continues to flow with the suspended crystals and impurities formed, the water will pass through the filter inside the cleaning component connector 7, so that the filter can adsorb and filter the suspended crystals and impurities formed in the water, reduce the impurities in the water, remove the organic matter from the microorganisms remaining in the water, further inhibit the growth of microorganisms, and prevent the water from becoming foul.

[0039] Furthermore, as the amount of impurities and suspended crystals adsorbed and filtered on the filter element increases, the resistance of water passing through the filter element also increases, causing the water to push the filter element. This, in turn, causes the filter element to slide along the inside of the slide groove 9 via the connector 7, which in turn causes the sealing sleeve 10 to slide along the inside of the housing 1 and compress the first spring 11 to contract. During this process, the connector 7 will pull the cleaning ring 5 along the inner wall of the electrode 4 via the connecting rod 6 to wipe away the impurities adhering to the inner wall of the electrode 4, preventing impurities from remaining on the inner wall of the electrode 4 and affecting normal operation.

[0040] The replacement components include a box 13 and a discharge sleeve 14 fixedly installed on the outer wall of the housing 1. The box 13 is located above the discharge sleeve 14. A water pipe 15 is fixedly connected between the box 13 and the housing 1. A sealing valve 16 is fixedly installed inside the water pipe 15. A guide hole 17 is opened inside the box 13. A box cover 18 is provided on the side of the box 13 away from the water pipe 15. A bolt 19 is inserted into the box cover 18. The bolt 19 is threaded into the inside of the box 13. A protective sleeve 20 is fixedly installed on the outer wall of the discharge sleeve 14. A second spring 21 is fixedly installed inside the protective sleeve 20. A connecting plate 22 is fixedly installed at the bottom of the second spring 21. A sealing plate 23 is fixedly installed on the outer wall of the connecting plate 22. The sealing plate 23 is slidably connected inside the discharge sleeve 14. Two hinges 24 are rotatably connected to one side of the sealing plate 23. The two hinges 24 are inserted into the inside of the discharge sleeve 14.

[0041] The replacement component is used to replace the clogged filter element to prevent the filter element from becoming clogged, which would affect the water flow and the adsorption and filtration effect on impurities.

[0042] Specifically, when the filter element is clogged and pushed by water, causing it to compress the first spring 11 via the connector 7 and connecting piece 8, the connection between the sealing sleeve 10 and the first spring 11 gradually moves to the top of the sealing plate 23. This causes the arc-shaped surface at the top of the sealing plate 23 to push the sealing sleeve 10 and the connector 7 apart, moving them away from each other. Consequently, the sealing plate 23, driven by the second spring 21 and the connecting plate 22, inserts between the connector 7 and the sealing sleeve 10, and works with the connector 7 to seal the housing 1, preventing water from draining out. At this point, water flows into the housing 13 through the sealing valve 16, pushing the partition plate 31 inside the housing 13, causing the partition plate 31 to push the filter element towards... Move away from the water pipe 15 until the filter element furthest from the water pipe 15 is blocked by the box cover 18 and stops. At this point, the partition plate 31 and the filter element cannot be pushed to move away from the water pipe 15. The water inside the box 13 will be guided by the guide hole 17 and push the filter element blocked by the box cover 18 to slide along the inside of the box 13 into the inside of the shell 1. This allows the filter element to push the filter element blocked inside the lower connector 7 into the discharge sleeve 14, and then enter the inside of the connector 7 and push the filter element blocked inside the connector 7 into the discharge sleeve 14. This achieves the effect of automatically replacing the blocked filter element and avoids the reduced adsorption filtration effect and water flow effect after the connector 7 is blocked, which would affect the water treatment.

[0043] Furthermore, during the process of the filter element inside the housing 13 pushing the clogged filter element inside the connector 7 into the discharge sleeve 14, the clogged filter element will push the sealing plate 23 to slide back along the inside of the discharge sleeve 14 through the hinge 24. This causes the sealing plate 23 to pull the second spring 21 through the connector 22 to extend and stop sealing the water inside the housing 1. When the sealing plate 23 is completely detached from the housing 1 and enters the discharge sleeve 14, the hinge 24 on the sealing plate 23 loses the obstruction on both sides of the discharge sleeve 14. Under the weight pressure of the clogged filter element, the two hinges 24 rotate to both sides, stopping the support for the clogged filter element and allowing the clogged filter element to detach from the inside of the discharge sleeve 14, thus avoiding obstructing the entry of subsequent filter elements into the discharge sleeve 14. It should be noted that during the process of the sealing plate 23 entering the housing 1 and returning to the discharge sleeve... When the filter element is inside the connector 7, the sealing plate 23 will slide along the outer wall of the sealing sleeve 10 through the second ball 30, reducing the resistance to the displacement of the sealing plate 23 and preventing the sealing plate 23 from being squeezed and fixed by the sealing sleeve 10 under the pushing pressure of the first spring 11 through the sealing sleeve 10, which would affect the normal operation of the replacement device. At the same time, when the filter element slides inside the connector 7, a groove will be formed at the connection between the first semi-circular ring 25 and the second semi-circular ring 26 of the filter element. The filter element can slide down along the inside of the first ball 29 inside the connector 7 through this groove, reducing the sliding resistance and ensuring that the filter element can be replaced normally to avoid jamming. At the same time, when the sealing plate 23 rises and inserts between the connector 7 and the sealing sleeve 10, the bottom of the connector 7 is provided with rounded corners to reduce the resistance of the sealing plate 23 in pushing the connector 7 and the sealing sleeve 10 apart.

[0044] Furthermore, after the filter element is replaced, the new filter element has less resistance to water flow, allowing the first spring 11 to push the sealing sleeve 10 back to its original position. This causes the sealing sleeve 10 to re-abut against the connector 7 and push the new filter element back to its original position through the connector 7. During this process, the connector 7 will drive the cleaning ring 5 through the connecting rod 6 to clean the inner wall of the electrode 4 again, preventing impurities from adhering to the inner wall of the electrode 4. The sealing sleeve 10 abuts against the connector 7 and resets, sealing the opening between the housing 1, the box 13, and the discharge sleeve 14, preventing water from being discharged through the opening connecting the housing 1 and the discharge sleeve 14, thus preventing water waste.

[0045] The filter element includes a first semicircular ring 25 and a second semicircular ring 26. The first semicircular ring 25 and the second semicircular ring 26 are interlocked with each other. An installation ring 27 is provided inside the first semicircular ring 25 and the second semicircular ring 26. Activated carbon filter media 28 is fixedly installed inside the installation ring 27. The number of filter elements is set to multiple. One filter element is set inside the connector 7, and the remaining filter elements are inserted into the box body 13. The multiple filter elements inside the box body 13 are provided with a partition plate 31 on the side near the water pipe 15.

[0046] The partition plate 31 is used to separate the filter elements inside the box body 13, so as to prevent water from flowing directly through multiple filter elements and being unable to enter the interior of the guide hole 17 to exert a downward pushing force on the filter element near the box cover 18.

[0047] A method for using a scale prevention, descaling, and corrosion prevention device includes the following steps:

[0048] S1. Connect the equipment to the pipe that needs to be prevented and descaled via the sealing flange 2, test the sealing performance of the equipment connected to the pipe, and test run the equipment;

[0049] S2. Start the equipment and open the pipeline valve so that the equipment electrode 4 forms a magnetic field that causes the calcium and magnesium ions in the water to form suspended crystals.

[0050] S3. Then the water will carry suspended crystals and impurities through the filter, which will adsorb and filter the suspended crystals and impurities in the water.

[0051] S4. As the amount of suspended crystals and impurities adsorbed and filtered on the filter element increases, the filter element will gradually become clogged, which increases the resistance of water flowing through the filter element. This causes the water to push the filter element, thereby driving the cleaning component and the replacement component to work. The cleaning component cleans the impurities adhering to the electrode 4, and the replacement component replaces the clogged filter element.

[0052] S5. After the filter element is replaced, the resistance of the filter element to water flow decreases, the cleaning component drives the filter element to reset, and the process ends.

[0053] Working principle: When the equipment is started and the pipeline valve is opened, a high-frequency electromagnetic field is generated at electrode 4, causing calcium and magnesium ions in the water flowing through electrode 4 to form suspended crystals. Subsequently, the water carries the suspended crystals and impurities through the filter element, which adsorbs and filters the suspended crystals and impurities in the water. As the number of suspended crystals and impurities adsorbed and filtered on the filter element increases, the filter element will gradually become clogged, increasing the resistance of the water flowing through the filter element. This causes the water to push the filter element, which in turn drives the cleaning and replacement components. The cleaning component cleans the impurities adhering to electrode 4, and the replacement component replaces the clogged filter element. After the filter element is replaced, the resistance of the filter element to the water flow decreases, and the cleaning component drives the filter element to reset, thus achieving the effect of automatically cleaning the impurities adhering to electrode 4 and automatically replacing the clogged filter element.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
