Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and more particularly to scale prevention, descaling and filtration equipment for water pipes. Background Technology

[0002] Changzhou Jintan Hengxu Technology Co., Ltd. has invented a copper-based catalyst alloy with anti-scaling function and its preparation method. Its components are eight metallic elements: Cu, Ni, Zn, Sn, Pb, Fe, Sb, and Mn. The weight percentages of each component are: Cu 40%-70%; Ni 5%-20%; Zn 10%-35%; Sn 5%-30%; Pb 0.5%-20%; Fe 0.1%-8%; Sb 0.01%-2%; and Mn 0.05%-5%. These components are synthesized at high temperature into a columnar crystal alloy that grows oriented along the S100 crystal axis. This alloy can both prevent scale formation and dissolve scale. The preparation method of this material is described in detail in Chinese Invention Patent 200810024432.0.

[0003] The invention of this special functional material has revolutionized the long-standing problem of scale buildup in water supply systems. Changzhou Jintan Hengxu Technology Co., Ltd. disclosed a civilian scale inhibitor and descaling device and its pipeline connection structure in CN201210092180.1. The device includes pipe fittings, sealing rings, scale inhibitor plates, a sleeve, spacers, screws, and nuts. All scale inhibitor plates are spaced apart and fitted onto the screw, then screwed in and secured by nuts. The scale inhibitor core component, consisting of scale inhibitor plates, spacers, screws, and nuts, is fitted into the cavity of the sleeve. Pipe fittings are screwed onto the external threads at both ends of the sleeve. An axial seal is achieved between the sleeve and the pipe fittings via sealing rings. This device can prevent and remove scale from main pipelines without power or chemicals, increasing pipeline lifespan and saving energy and protecting the environment. The pipe fittings, scale inhibitor plates, sleeve, and spacers are all made of copper-based catalyst alloy.

[0004] The background technology section of CN201210092180.1 describes the application scenarios of this technology. Water pipelines are essential in water treatment and heating processes in industries such as petroleum, chemical, power, papermaking, printing and dyeing, and heating. Scale builds up in these pipelines during long-term high-temperature use. This buildup can range from affecting normal industrial production to causing system shutdowns or equipment explosions. Water purification is applied in various production and living technology fields and is indispensable in both production and daily life. Scale is a major enemy of hot water heat exchange equipment such as water pipes, boilers, tea boilers, and water heaters.

[0005] Although this scale inhibitor / descaler has scale prevention and removal functions, it lacks filtration capabilities. Currently, there is no integrated device in this field that combines scale prevention / descaler function with water filtration and purification for a water supply system. In practical applications, the scale inhibitor / descaler typically needs to be used in series with a water filter to achieve both scale prevention / descaler treatment of the water pipes and water filtration and purification. In this configuration, the contact area between the water and the copper-based catalyst alloy within the scale inhibitor / descaler is limited, the water flow path is short, and the scale prevention / descaler treatment time is short, leaving considerable room for improvement in scale prevention and removal efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-tube stacked horizontal anti-scaling and descaling filter and purifier, which can improve the anti-scaling and descaling efficiency of CN201210092180.1, while also having a filtration function, thus realizing the combination of anti-scaling and descaling device and water filtration and purifier.

[0007] The technical solution adopted in this invention is: A multi-tube stacked horizontal anti-scaling and descaling filter includes an inlet end cap, an outlet end cap, an inner tube, a middle tube, an outer tube, a descaling inlet baffle, descaling particles, an inner spiral guide cage, and an outer spiral guide cage. The inner tube, middle tube, and outer tube are coaxially and sealed between the inlet end cap and the outlet end cap. A first outlet hole is provided on the right side wall of the inner tube, and a second outlet hole is provided on the left side wall of the middle tube. An inlet hole is provided at the center of the inlet end cap, communicating with the inner hole of the inner tube. An axial outlet and a vertical outlet are provided on the outlet end cap. The axial outlet communicates with the annular cavity formed between the middle tube and the outer tube, and the vertical outlet communicates with the axial outlet and is located at the highest point of the outlet end cap. Descaling particles are provided at intervals in the inner hole of the inner tube. The descaling inlet baffles are filled with descaling particles between all the descaling inlet baffles. The inner spiral guide cage is set in the first annular flow channel formed by the inner tube and the middle tube. The three form a first spiral channel. Water flowing out of the first outlet hole flows slowly to the left in the first spiral channel under the guidance of the inner spiral guide cage. The outer spiral guide cage is set in the second annular flow channel formed by the middle tube and the outer tube. The three form a second spiral channel. Water flowing out of the second outlet hole flows slowly to the right in the second spiral channel under the guidance of the outer spiral guide cage. Descaling particles are filled in both the first and second spiral channels. The inlet end cap, outlet end cap, inner tube, middle tube, outer tube, descaling particles, inner spiral guide cage and outer spiral guide cage are all made of copper-based catalyst alloy.

[0008] As an optimization of this solution, a first annular adjusting mesh plate and a second annular adjusting mesh plate are provided between the inner spiral guide cage and the outer spiral guide cage and the outlet end cover. The first annular adjusting mesh plate and the second annular adjusting mesh plate are controlled by a synchronous adjusting mechanism to move axially to adjust the distribution density of descaling particles in the first spiral channel and the second spiral channel.

[0009] As an optimization of this solution, the synchronous adjustment mechanism includes a first annular adjustment mesh plate, a second annular adjustment mesh plate, a slide rod, a synchronous moving plate, and a screw adjustment handwheel. The slide rod is fixedly and circumferentially on the first and second annular adjustment mesh plates. The slide rod is slidably fitted onto the water outlet end cover. The other end of the slide rod is fixed to the synchronous moving plate. A threaded hole is provided at the center of the synchronous moving plate. The screw adjustment handwheel is screwed into the threaded hole. The top end of the screw of the screw adjustment handwheel is rotatably installed at the center of the water outlet end cover. Rotating the screw adjustment handwheel can synchronously drive the first annular adjustment mesh plate and the second annular adjustment mesh plate 82 to move axially within the first and second annular flow channels.

[0010] As an optimization of this solution, the synchronous moving plate is either a straight rod or three rods evenly distributed.

[0011] As an optimization of this solution, multiple first water outlet holes are provided at intervals along the circumference on the right side wall of the inner tube, and multiple second water outlet holes are provided at intervals along the circumference on the left side wall of the middle tube. The diameter of both the first and second water outlet holes is smaller than the particle size of the descaling particles.

[0012] As an optimization of this solution, the descaling particles are hollow granules or honeycomb-shaped, with water seepage holes between their outer wall and inner cavity.

[0013] As an optimization of this solution, a right inlet hole is provided on the right end plate of the inner spiral guide cage to ensure that the water flowing out from the right end of the inner tube can enter the first spiral channel formed by the inner tube, the inner spiral guide cage and the intermediate tube. A left inlet hole is provided on the right end plate of the outer spiral guide cage to ensure that the water flowing out from the left end of the first spiral channel can enter the second spiral channel formed by the intermediate tube, the outer spiral guide cage and the outer tube.

[0014] As an optimization of this solution, a sludge storage chamber is provided inside the water outlet end cover, a sludge cleaning port is provided at the lower end of the sludge storage chamber, and a sludge drain plug is provided at the sludge cleaning port.

[0015] As an optimization of this solution, a filter element is installed inside the vertical water outlet, with a plastic elbow screwed in, and a plastic-coated magnetic decontamination bead is installed above the filter element.

[0016] As an optimization of this solution, a left inner ring groove, a left middle ring groove and a left outer ring groove are provided on the right end face of the water inlet end cover, and a right inner ring groove, a right middle ring groove and a right outer ring groove are provided on the left end face of the water outlet end cover, with a sealing element provided in all the ring grooves.

[0017] Its working principle is as follows: When water flows into the inner pipe from the inlet of the inlet cap, it comes into full contact with the descaling inlet baffle and descaling particles in sequence. Then, it flows from the first outlet on the right side wall of the inner pipe into the first annular flow channel formed by the inner pipe and the intermediate pipe, and then through the second outlet on the left end of the intermediate pipe into the second annular flow channel formed by the intermediate pipe and the outer pipe. Because an inner spiral guide cage is provided in the first annular flow channel, a first spiral channel is formed. An outer spiral guide cage is provided in the second annular flow channel, thus forming a second spiral channel. The vortex channel and the second spiral channel are equipped with descaling particles. This allows the incoming water to flow sequentially through the inner pipe, intermediate pipe, and outer pipe, forming a three-fold winding path for scale prevention, removal, and purification. The water makes full contact with the inner pipe, intermediate pipe, outer pipe, descaling inlet baffle, and descaling particles, resulting in a longer flow path and a longer residence time. This significantly increases the contact probability, area, and duration between the water and the copper-based catalyst alloy, leading to more thorough removal of scale-forming substances and better scale prevention and removal effects. Because the descaling particles are designed as hollow granules or honeycomb structures with permeable pores between their outer wall and inner cavity, this not only increases the contact surface area with the water but also filters and purifies the water. By changing the distribution density of the descaling particles throughout the water flow channel, the filtration and purification effect and the water output can be adjusted.

[0018] In this scheme, the addition of a synchronous adjustment mechanism is to adjust the distribution density of descaling particles throughout the water flow channel.

[0019] The synchronous adjustment mechanism in this scheme includes a first annular adjustment mesh plate, a second annular adjustment mesh plate, a slide rod, a synchronous moving plate, and a screw adjustment handwheel. The slide rod is fixedly fixed to the first and second annular adjustment mesh plates in equal circumferential directions. The slide rod is slidably fitted onto the water outlet end cover in a sealed manner. The other end of the slide rod is fixed to the synchronous moving plate. A threaded hole is provided at the center of the synchronous moving plate. The screw adjustment handwheel is screwed into the threaded hole. The top of the screw of the screw adjustment handwheel is rotatably installed at the center of the water outlet end cover. Rotating the screw adjustment handwheel can synchronously drive the first annular adjustment mesh plate and the second annular adjustment mesh plate to move axially within the first and second annular flow channels.

[0020] If the synchronous moving plate adopts a straight rod structure, two sliding rods are symmetrically fixed circumferentially on the first and second annular adjusting mesh plates. If a three-rod distribution structure is adopted, three sliding rods are evenly fixed circumferentially on the first and second annular adjusting mesh plates. In this way, rotating the screw adjusting handwheel can synchronously drive the first and second annular adjusting mesh plates to move axially within the first and second annular flow channels, thereby adjusting the distribution density of descaling particles in the first and second spiral channels to adjust the filtration and purification effect and the water flow rate.

[0021] If a filter element is installed inside the vertical water outlet, the water can be filtered and purified a second time. If a plastic-coated magnetic decontamination bead is installed above the filter element, the magnetic decontamination bead can be periodically controlled to vibrate and remove dirt from the filter element.

[0022] If a sludge storage chamber is provided inside the water outlet cap, a sludge cleaning port is provided at the lower end of the sludge storage chamber, and a sludge drain plug is provided at the sludge cleaning port, it is convenient to remove filtered dirt during later use.

[0023] Because this invention employs a simple and convenient three-pipe assembly structure, the inner pipe, middle pipe, outer pipe, descaling inlet baffle, descaling particles, inner spiral guide cage, and outer spiral guide cage are all made of copper-based catalyst alloy with anti-scaling and descaling functions. The water flow channel is filled with descaling particles, which are hollow granules or honeycomb-shaped, with seepage holes between their outer wall and inner cavity. This structural design not only improves the anti-scaling and descaling function of the water, eliminating and slowing down scale formation in the water pipes, but also filters and purifies the water. The water makes full contact with the copper-based catalyst alloy inner pipe, middle pipe, outer pipe, descaling inlet baffle, descaling particles, inner spiral guide cage, and outer spiral guide cage, ensuring thorough filtration and purification of the water through the densely distributed descaling particles. This prevents scale buildup in the water pipes and makes the outflowing water cleaner. In future use and maintenance, it can be periodically disassembled, cleaned, and reassembled for reuse, increasing the service life of the pipes and contributing to energy conservation and environmental protection.

[0024] If a sludge collection chamber is provided inside the water outlet cover, and a sludge removal port is provided at the lower end of the sludge collection chamber, and the sludge plug is sealed in the sludge removal port, it will be easier to remove the filtered dirt during later use.

[0025] This invention requires no electricity or manpower, has no moving parts, requires no daily maintenance, is simple to use and install, saves manufacturing and usage costs, and has a wide range of applications. Attached Figure Description

Detailed Implementation

[0027] Example 1: A multi-tube stacked horizontal anti-scaling and descaling filter purifier, such as Figure 1-6As shown, the device includes an inlet cap 1, an outlet cap 2, an inner tube 3, a middle tube 4, an outer tube 5, a descaling inlet baffle 6, descaling particles 7, an inner spiral guide cage 8, and an outer spiral guide cage 9. Multiple first outlet holes 31 are evenly distributed on the right side wall of the inner tube 3, and multiple second outlet holes 41 are evenly distributed on the left side wall of the middle tube 4. The diameters of the first and second outlet holes 31 are both smaller than the particle size of the descaling particles 7. An inlet hole 11 is located at the center of the inlet cap 1, communicating with the inner hole of the inner tube 3. A left inner annular groove 12, a left middle annular groove 13, and a left outer annular groove 14 are provided on the right end face of the inlet cap 1. A right inner annular groove 25 and a right middle annular groove are provided on the left end face of the outlet cap 2. 26 and the right outer annular groove 27, all annular grooves are equipped with seals. The left end of the inner tube 3 is fitted into the left inner annular groove 12, and the right end of the inner tube 3 is fitted into the right inner annular groove 25. The left end of the middle tube 4 is fitted into the left middle annular groove 13, and the right end of the middle tube 4 is fitted into the right middle annular groove 26. The left end of the outer tube 5 is fitted into the left outer annular groove 14, and the right end of the outer tube 5 is fitted into the right outer annular groove 27. The three are coaxially and sealedly fixed between the inlet end cover 1 and the outlet end cover 2. The outlet end cover 2 is provided with an axial outlet 21 and a vertical outlet 22. The axial outlet 21 communicates with the first annular flow channel formed between the middle tube 4 and the outer tube 5. The vertical outlet 22 communicates with the axial outlet 21 and discharges water vertically. The outlet 22 is located at the highest point of the outlet end cap 2; descaling inlet baffles 6 are spaced apart in the inner hole of the inner tube 3, and descaling particles 7 are installed between all the descaling inlet baffles 6. The inner spiral guide cage 8 is set in the first annular flow channel formed by the inner tube 3 and the intermediate tube 4, and the three form a first spiral channel. Water flowing out of the first outlet 31 flows slowly to the left in the first spiral channel through the guidance of the inner spiral guide cage 8; the outer spiral guide cage 9 is set in the second annular flow channel formed by the intermediate tube 4 and the outer tube 5, and the three form a second spiral channel. Water flowing out of the second outlet 41 flows slowly to the right in the second spiral channel through the guidance of the outer spiral guide cage 9, and the three form a second spiral channel. Each spiral channel is filled with descaling particles 7. The inlet cap 1, outlet cap 2, inner tube 3, intermediate tube 4, outer tube 5, descaling particles 7, inner spiral guide cage 8, and outer spiral guide cage 9 are all made of copper-based catalyst alloy. The descaling particles 7 are hollow granules or honeycomb-shaped, with seepage holes between their outer wall and inner cavity. A right inlet hole is provided on the right end plate of the inner spiral guide cage 8 to ensure that the water flowing out from the right end of the inner tube 3 can enter the first spiral channel formed by the inner tube 3, inner spiral guide cage 8, and intermediate tube 4. A left inlet hole is provided on the right end plate of the outer spiral guide cage 9 to ensure that the water flowing out from the left end of the first spiral channel can enter the second spiral channel formed by the intermediate tube 4, outer spiral guide cage 9, and outer tube 5. A right inner annular groove 25, a right middle annular groove 26, and a right outer annular groove 27 are respectively provided on the left end face of the outlet cap 2, and a sealing element is provided in all annular grooves.

[0028] Example 2: Based on Example 1, a dirt storage chamber 23 is provided inside the water outlet cap 2, a dirt cleaning port 24 is provided at the lower end of the dirt storage chamber 23, and a drain plug is provided at the dirt cleaning port 24.

[0029] Example 3: Based on Example 1, a filter element 10 is provided inside the vertical water outlet 22. A plastic-coated magnetic vibrating bead 101 is provided above the filter element 10, led out through a plastic elbow 102. During use, a strong magnetic block 103 is placed directly above the plastic-coated magnetic vibrating bead 101, attracting it and keeping it suspended. At each maintenance cycle, the strong magnetic block 103 is removed, causing the plastic-coated magnetic vibrating bead 101 to fall. Under the impulse of the water flow, the plastic-coated magnetic vibrating bead 101 continuously vibrates the filter element 10, removing the dirt adsorbed on it, achieving self-cleaning. The shaken-off dirt falls into the dirt storage chamber 23 inside the water outlet cap 2. A cleaning port 24 is provided at the lower end of the dirt storage chamber 23, and a drain plug is provided at the cleaning port 24 for easy removal of filtered dirt during later use. Figure 1 , Figure 7 , Figure 8 As shown.

[0030] Example 4: Figures 9-13 As shown, a first annular adjusting mesh plate 81 and a second annular adjusting mesh plate 82 are respectively provided between the inner spiral guide cage 8 and the outer spiral guide cage 9 and the outlet end cover 2. The first annular adjusting mesh plate 81 and the second annular adjusting mesh plate 82 are controlled by a synchronous adjusting mechanism to move synchronously along the axial direction. The synchronous adjusting mechanism includes the first annular adjusting mesh plate 81, the second annular adjusting mesh plate 82, a slide rod 83, a synchronous moving plate 84, and a screw adjusting handwheel 85. The slide rod 83 is fixed evenly along the circumference of the first annular adjusting mesh plate 81 and the second annular adjusting mesh plate 82. The sealing sliding sleeve is mounted on the water outlet end cover 2. The other end of the slide rod 83 is fixed on the synchronous moving plate 84. A threaded hole is provided at the center of the synchronous moving plate 84. The screw adjusting handwheel 85 is screwed into the threaded hole. The screw end of the screw adjusting handwheel 85 is rotatably mounted on the water outlet end cover 2 through two hinged fixed blocks 86. Rotating the screw adjusting handwheel 85 can synchronously drive the first annular adjusting mesh plate 81 and the second annular adjusting mesh plate 82 to move axially within the first annular flow channel and the second annular flow channel. In this way, the distribution density of descaling particles 7 in the first spiral channel and the second spiral channel can be adjusted.

[0031] In this example, the synchronous moving plate 84 is in the shape of a straight rod, such as... Figure 10 , 11 , Figure 12As shown, the first annular adjusting mesh plate 81 and the second annular adjusting mesh plate 82 are respectively mounted on the water outlet end cover 2 by two sliding rods 83. The four sliding rods 83 are sealed and slidably fitted on the water outlet end cover 2, and the right end of the sliding rods 83 is fixed on the synchronous moving plate 84.

[0032] Example 5: The difference from Example 4 is that the synchronous moving plate 84 adopts a three-bar distributed structure, such as... Figure 13 As shown, the first annular adjusting mesh plate 81 and the second annular adjusting mesh plate 82 are respectively fixed to the synchronous moving plate 84 along the circumferential direction by three sliding rods 83. Two sliding rods 83 are fixed on each support rod. This structure makes the adjustment more stable.

[0033] In Examples 4 and 5, when the first annular adjusting mesh plate 81 and the second annular adjusting mesh plate 82 are pushed to the leftmost position, the distribution density of the descaling particles 7 is the highest, the filtration and purification effect is the best, and the outflow rate is the lowest. Conversely, when the first annular adjusting mesh plate 81 and the second annular adjusting mesh plate 82 are pulled to the rightmost position, the distribution density of the descaling particles 7 is the lowest, the outflow rate is the highest, and the purification effect will be slightly reduced.

[0034] Because the present invention adopts a simple and convenient three-tube assembly structure, the inner tube 3, the middle tube 4, the outer tube 5, the descaling inlet baffle 6, the descaling particles 7, the inner spiral guide cage 8, and the outer spiral guide cage 9 are all made of copper-based catalyst alloy with anti-scaling and descaling functions. The descaling particles 7 are installed in the channel through which the water flows. The descaling particles 7 are hollow granules or honeycomb-shaped, and there are seepage holes between their outer wall and inner cavity. In the above embodiment, the pore diameter of the first water outlet 31, the second water outlet 41, and the filter hole 61 is 1~2 mm, and the descaling particles 7 are spherical with a diameter of 2.1 mm. This structural design enhances the scale prevention and removal capabilities of the water, reducing and eliminating scale formation in the water pipes. It also filters and purifies the water. The water makes full contact with the inner pipe 3, middle pipe 4, outer pipe 5, descaling inlet baffle 6, descaling particles 7, inner spiral guide cage 8, and outer spiral guide cage 9, all made of copper-based catalyst alloy with scale prevention and removal functions. The water is filtered and purified by the densely distributed descaling particles 7 throughout, preventing scale buildup in the pipes and resulting in cleaner outflowing water. In future use and maintenance, it can be periodically disassembled, cleaned, and reassembled, extending the pipe's lifespan and contributing to energy conservation and environmental protection. This invention requires no electricity or manpower, has no moving parts, requires no daily maintenance, is simple to use and install, saves manufacturing and operating costs, and has a wide range of applications.

[0035] Although this invention only describes a stacked horizontal anti-scaling and descaling filter purifier with inner tube 3, middle tube 4, and outer tube 5, the number of middle tubes 4 can actually be increased. As long as the improved ideas of this invention are adopted, the contact time between the water and the copper-based catalyst alloy is increased through the water flow path, the contact area is increased, and all technical solutions that utilize the descaling particles 7 as a filter and purifier are within the scope of this invention.
