Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to a multi-purpose circulating water treatment device based on a nano-rare earth coating. Background Technology

[0002] A multi-purpose circulating water treatment device based on nano-rare earth coating is a purely physical circulating water treatment equipment that integrates scale prevention and removal, sterilization and algae removal, corrosion prevention and water purification, with nano-rare earth functional coating as its core. It is mainly used in industrial / civilian circulating water systems (air conditioning, cooling, HVAC, chemical, power, etc.). The entire process requires no chemical agents, relying on the synergistic effect of material physical properties and photocatalysis / physical field to achieve water quality stability and system protection. Existing technical solutions have the following defects: On the one hand, traditional fixed-structure rare earth coating components are immersed in circulating water for a long time. Sludge, colloids, microorganisms and precipitated minerals in the water are very easy to adhere and accumulate on the coating surface, forming a mud and scale layer, which blocks the catalytic active sites and leads to a continuous decline in water treatment efficiency. On the other hand, although some devices have certain catalytic functions, they lack an effective self-cleaning mechanism. The dirt on the coating surface cannot be removed in time. Long-term exposure to dirt and water erosion not only deteriorates the treatment effect, but also accelerates the aging and peeling of the coating, shortening the service life of the device. Therefore, a multi-purpose circulating water treatment device based on nano-rare earth coating is proposed to solve the above-mentioned problems. Summary of the Invention

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-10 This invention provides a technical solution: a multi-purpose circulating water treatment device based on a nano-rare earth coating, comprising an outer casing 1, a base 2 fixedly installed at the bottom of the outer casing 1, anti-slip pads 3 fixedly installed at both ends of the bottom of the base 2, a top cover 4 movably installed on the inner top wall of the outer casing 1, a discharge pipe 10 extending to the right side of the inner wall of the outer casing 1 fixedly installed on the right side, a drive mechanism 5 extending to the inner side of the outer casing 1 provided at the top of the top cover 4, a catalytic mechanism 6 connected to the bottom of the top cover 4 provided at the bottom of the drive mechanism 5, a filter mechanism 7 provided on the inner side of the outer casing 1, the catalytic mechanism 6 extending to the inner side of the filter mechanism 7, a cleaning mechanism 8 fitting with the catalytic mechanism 6 provided on the inner side of the filter mechanism 7, and a transmission mechanism 9 connected to the drive mechanism 5 and the top of the outer casing 1 provided at the top of the top cover 4, the transmission mechanism 9 extending to the inner side of the outer casing 1 and located above the cleaning mechanism 8.

[0034] The top cover 4 is connected to the outer box 1 by a hinge. A sealing strip is fixedly installed at the bottom of the top cover 4. The sealing strip is made of silicone rubber. A handle is fixedly installed at the top of the top cover 4. An inspection door is opened on the front side of the inner wall of the outer box 1. A transparent observation window is installed on the inspection door.

[0035] The outer casing 1 serves as the main body of the overall container, bearing all internal components and providing a sealed processing space to prevent water leakage and external contamination. The bottom is equipped with a base 2 and anti-slip pads 3 to ensure the stability of the device. The inner wall is insulated with a layer of polyurethane foam to reduce heat loss. The top cover 4 is connected to the outer casing 1 by a hinge and has an openable design for easy internal maintenance and component replacement. The bottom silicone rubber sealing strip ensures airtightness and prevents water vapor from overflowing. The top is equipped with a handle for easy opening. The maintenance door (with a transparent observation window) allows for real-time monitoring of the internal operating status. The base 2 and anti-slip pads 3 distribute the weight of the device, and the anti-slip pads 3 (rubber material) increase friction to prevent displacement due to vibration during operation. The inlet pipe 11 introduces the water to be treated into the treatment tank 72, and the outlet pipe 10 outputs the purified water to the circulation system.

[0036] The drive mechanism 5 includes a motor frame 51. The motor frame 51 is fixedly installed on the top of the top cover 4. A motor 52 is fixedly installed on the inner top wall of the motor frame 51. A rotating shaft 53 extending to the bottom of the top cover 4 is fixedly installed at the output shaft of the motor 52. An active gear 54 located above the top cover 4 is fixedly installed on the outer side of the rotating shaft 53.

[0037] The motor frame 51 fixes the motor 52, isolates moisture and dust, and extends the motor life. The motor 52 provides rotational power, which drives the catalytic mechanism 6 and the transmission mechanism 9 to operate synchronously through the rotating shaft 53. The driving gear 54 transmits the rotational force of the motor 52 to the driven gear 904, realizing power splitting (driving the catalytic mechanism 6 and the transmission mechanism 9).

[0038] The catalytic mechanism 6 includes a circular block 601. The circular block 601 is fixedly mounted on one bottom end of the rotating shaft 53. Six mounting slots 602 are formed at the bottom of the circular block 601. A support rod 603 is fixedly mounted on the inner side of each mounting slot 602. A swing plate 604 extending to the outer side of the mounting slot 602 is rotatably connected to the outer side of the support rod 603. A fixing cylinder 605 is fixedly mounted on the inner top wall of the mounting slot 602. A component connected to the top of the swing plate 604 is fixedly mounted on the inner side of the fixing cylinder 605. A return spring 606 is fixedly connected to the top cover 4. A rotating rod 607 extending to the bottom of the swing plate 604 is rotatably connected to the inner side of the swing plate 604. A coated block 608 is fixedly installed at the bottom of the rotating rod 607. A cylinder 609 located above the swing plate 604 is fixedly installed at the bottom of the top cover 4. A trapezoidal plate 610 is fixedly installed at the front end of the bottom of the cylinder 609. The swing plate 604 is slidably connected to the bottom of the cylinder 609. The front swing plate 604 is slidably connected to the bottom of the trapezoidal plate 610.

[0039] The circular block 601 and the mounting groove 602 serve as the mounting base for the swing plate 604. The six mounting grooves 602 are evenly distributed to ensure that the coating block 608 covers a larger treatment area. The support rod 603 allows the swing plate 604 to swing freely within a certain angle. The swing plate 604 unfolds through the trapezoidal plate 610, causing the coating block 608 to dynamically contact the water body and improve catalytic efficiency. The reset spring 606 connects the swing plate 604 and the fixed cylinder 605, providing a rebound force so that the swing plate 604 swings periodically during rotation, enhancing the mixing effect between the coating block 608 and the water. The rotating rod 607 allows the coating block 608 to rotate freely and adapt to the water flow direction. The surface of the coating block 608 is coated with a nano-rare earth catalytic coating (such as cerium oxide), which decomposes organic matter and kills bacteria and algae through catalytic reaction. The cylindrical cylinder 609 limits the swing range of the swing plate 604, and the trapezoidal plate 610 further constrains the swing angle of the front swing plate 604 to ensure that the coating block 608 is always immersed in water and avoids idling.

[0040] The filtration mechanism 7 includes a tray 71. The tray 71 is fixedly installed between the left and right sides of the inner wall of the outer casing 1. A treatment tank 72 is movably installed on the top of the tray 71. A filter cartridge 73 is movably installed on the top of the treatment tank 72. An inlet pipe 11 is fixedly installed on the right side of the inner wall of the outer casing 1, penetrating and extending to the inside of the treatment tank 72. A front coating block 608 extends to the inside of the treatment tank 72.

[0041] The support plate 71 supports the treatment tank 72 and fixes its position to prevent the tank from shifting due to water pressure. The treatment tank 72 contains the water to be treated. It is equipped with a drain pipe and an electric drain valve at the bottom. Sediment is automatically discharged through a liquid level sensor. The filter cartridge 73 is designed to be detachable (flange connection). It has multiple filter layers inside (activated carbon, PP cotton, quartz sand, etc.). The side wall filter holes (pore diameter 1-5mm) trap suspended solids and particles. The filter layer combination can be adjusted according to water quality requirements.

[0042] A drain pipe is fixedly installed at the bottom of the treatment tank 72, extending to the outside of the outer casing 1. An electric drain valve is installed on the drain pipe. A liquid level sensor is fixedly installed on the inner wall of the treatment tank 72, and the liquid level sensor is electrically connected to the electric drain valve. The filter holes on the side wall of the filter cartridge 73 can be set according to requirements, and the diameter of the filter holes is one to five millimeters. One or more of the following are fixedly installed on the inner side of the filter cartridge 73: activated carbon filter layer, PP cotton filter layer, and quartz sand filter layer. The filter cartridge 73 and the treatment tank 72 are detachably connected by a flange structure. The outer surface of the coating block 608 is coated with a nano-rare earth catalytic coating. The raw materials of the nano-rare earth catalytic coating include one or more of cerium oxide, lanthanum oxide, and neodymium oxide. The coating surface has a porous structure with a porosity of 20% to 40%.

[0043] A heating tube is fixedly installed on the inner side of the outer casing 1. The heating tube is located below the treatment tank 72. The heating tube is electrically connected to a temperature controller. The temperature setting range of the temperature controller is 20℃-80℃. An insulation layer is fixedly installed on the inner wall of the outer casing 1. The insulation layer is made of polyurethane foam.

[0044] Heating elements maintain the water temperature in treatment tank 72 at 20-80℃ to optimize catalytic reaction efficiency (e.g., high temperature enhances oxidation capacity). Temperature controllers precisely control the temperature to avoid energy waste. Level sensors monitor the water level in treatment tank 72 and automatically discharge sediment via an electric drain valve to prevent clogging of filter cartridge 73.

[0045] The cleaning mechanism 8 includes an arc-shaped plate 81. The arc-shaped plate 81 is slidably installed on the front side of the inner wall of the treatment tank 72. Four fixed plates 82 are fixedly installed on the front side of the inner wall of the filter cartridge 73. A telescopic spring 83 is fixedly installed between the fixed plate 82 and the arc-shaped plate 81. A cleaning brush 84 that fits against the front coating block 608 is fixedly installed on the rear side of the arc-shaped plate 81. A connecting plate 85 is fixedly installed on the top of the arc-shaped plate 81. A rectangular plate 86 is fixedly installed on the top of the connecting plate 85.

[0046] There are four telescopic springs 83, with an elastic coefficient of 5N / mm-20N / mm. A guide block is fixedly installed on the front side of the arc plate 81 and slidably connected to the inner wall of the treatment pool 72. The inner wall of the treatment pool 72 has a guide groove adapted to the guide block. The cleaning brush 84 is one of a nylon brush, a wire brush, or a silicone brush. The bristle length of the cleaning brush is 10 to 30 mm, and the bristle density is 50-200 bristles / cm². The cleaning brush 84 and the arc plate 81 are detachably connected by bolts.

[0047] The arc-shaped plate 81 slides along the inner wall of the treatment tank 72. The guide block and guide groove cooperate to ensure accurate movement trajectory and avoid jamming. The fixed plate 82 connects the filter cartridge 73 and the arc-shaped plate 81. The telescopic spring 83 (elastic coefficient 5-20N / mm) provides rebound force, so that the cleaning brush 84 always fits in contact with the surface of the coating block 608. The cleaning brush 84 has a detachable design (bolted connection). The material can be selected from nylon (soft), steel wire (hard) or silicone (corrosion resistant). The bristle length is 10-30mm and the density is 50-200 bristles / cm². It effectively removes the deposits on the surface of the coating block 608 and maintains catalytic activity. The connecting plate 85 and the rectangular plate 86 transmit the thrust of the cam 910, converting the rotational motion into the linear reciprocating motion of the arc-shaped plate 81.

[0048] The transmission mechanism 9 includes a support base 901. The support base 901 is fixedly installed on the top of the top cover 4, located in front of the motor frame 51. The top of the outer casing 1 is fixedly installed on the top of the outer casing 1, located in front of the support base 901. The rear side of the vertical plate 902 is rotatably connected to a rotating shaft 903 extending to the rear side of the support base 901. One end of the rear side of the rotating shaft 903 is fixedly installed with a driven gear 904 that meshes with the driving gear 54. The outer side of the rotating shaft 903 is fixedly installed with a driving wheel 905 located in front of the support base 901. The bottom of the top cover 4 is fixedly installed with a vertical plate 906. The rear side of the vertical plate 906 is rotatably connected with a rotating rod 907. The outer side of the rotating rod 907 is fixedly installed with a driven wheel 908 located below the driving wheel 905. The outer side of the driving wheel 905 and the outer side of the driven wheel 908 are connected by a belt 909 that passes through the inner top wall of the outer casing 1. The outer side of the rotating rod 907 is fixedly installed with a cam 910 located above the rectangular plate 86.

[0049] Both the driving pulley 905 and the driven pulley 908 are synchronous pulleys, the belt 909 is a synchronous belt, the tooth shape of the synchronous belt is trapezoidal teeth or circular arc teeth, and the outer side of the cam 910 is fitted with a rubber buffer sleeve, the thickness of which is two to five millimeters.

[0050] The support base 901 and the vertical plate 902 fix the rotating shaft 903, ensuring stable meshing between the driven gear 904 and the driving gear 54. The driven gear 904 transmits the motor power to the driving wheel 905. The driving wheel 905 drives the driven wheel 908 through the belt 909, forming a two-stage transmission, reducing the speed and increasing the torque. The belt 909 (synchronous belt) has a trapezoidal or circular arc tooth design to prevent slippage, ensuring that the driving wheel 905 and the driven wheel 908 rotate synchronously, resulting in high transmission accuracy. When the cam 910 rotates, it periodically squeezes the rectangular plate 86, driving the cleaning mechanism 8 to reciprocate. The rubber buffer sleeve (thickness 2-5mm) reduces mechanical impact and extends the service life of the components.

[0051] In use, place the device on a stable surface, connect the inlet pipe 11 and the outlet pipe 10, check the stability of the anti-slip mat 3, inject the water to be treated into the treatment tank 72 through the inlet pipe 11, connect the power supply, set the temperature of the thermostat (e.g., 50℃), start the motor 52, the motor 52 drives the coating block 608 to swing, catalyzing the decomposition of pollutants, the heating element maintains a suitable temperature, the water flows out from the outlet pipe 10 after being filtered through multiple layers of the filter cartridge 73, and is recycled. The cam 910 rotates several times per minute, and the cleaning brush 84 automatically removes dirt from the surface of the coating block 608, avoiding catalytic decomposition. If the catalytic efficiency decreases, open the maintenance door every 2-4 weeks to check the filter cartridge 73 for blockage, and replace or clean the filter layer. If the catalytic efficiency decreases, the coating block 608 can be disassembled for regeneration. According to the liquid level sensor signal, discharge the sediment at the bottom of the treatment tank 72 regularly through the electric drain valve. Check the aging of the sealing strip every six months and replace it in time to prevent water leakage. When shutting down, turn off the motor 52 and heating tube, disconnect the power supply, open the drain pipe to discharge the remaining water, and clean the inside of the device. When not in use for a long time, keep the top cover 4 open to avoid internal moisture causing corrosion of the components.

[0052] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0053] In summary, this multi-purpose circulating water treatment device based on a nano-rare earth coating, through the setting of a drive mechanism 5 and a catalytic mechanism 6, uses a motor 52 to drive the drive gear 54 to rotate via a rotating shaft 53, which in turn drives the catalytic mechanism 6 to work. The rotating shaft 53 drives the circular block 601 to rotate, and the swing plate 604 rotates synchronously under its drive. When the swing plate 604 moves below the trapezoidal plate 610, it swings downwards. When it is no longer in contact with the trapezoidal plate 610, the return spring 606 provides a rebound force, forming a periodic swing. The coating block 608 moves with the swing plate 604, making full contact with the water, catalyzing the generation of strong oxidizing substances such as hydroxyl radicals, decomposing organic matter, and killing bacteria and algae. This realizes a movable catalytic reaction structure. Through the setting of a cleaning mechanism 8 and a transmission mechanism 9, the drive gear 54 drives the rotating shaft 903 to rotate via a driven gear 904, and the drive wheel 905 drives the driven wheel 908 via a belt 909. The rotating rod 907 and cam 910 rotate, and cam 910 periodically squeezes rectangular plate 86, which pushes arc plate 81 up and down through connecting plate 85. Cleaning brush 84 removes deposits from the surface of coating block 608, and telescopic spring 83 assists in resetting. While the coating block 608 is in the water, it is self-cleaned by cleaning brush 84, thus achieving the purpose of self-cleaning. This solves the problems of traditional fixed structure rare earth coating components being submerged in circulating water for a long time, where sludge, colloids, microorganisms and precipitated minerals in the water easily adhere and accumulate on the coating surface, forming a mud and scale layer that obscures catalytic active sites and leads to a continuous decline in water treatment efficiency. On the other hand, although some devices have certain catalytic functions, they lack an effective self-cleaning mechanism, and the dirt on the coating surface cannot be removed in time. Long-term exposure to dirt and water erosion not only worsens the treatment effect but also accelerates coating aging and peeling, shortening the service life of the device.
