Description

Technical Field

[0001] This invention relates to the field of decontaminator technology, and specifically to a spiral degassing decontaminator. Background Technology

[0002] The spiral degassing and descaling device is an industrial equipment that can simultaneously remove gas (microbubbles) and solid impurities from circulating water systems; it combines degassing and filtration functions, which can effectively improve the operating efficiency and service life of heating, cooling and other systems.

[0003] Chinese patent CN215161513U discloses a spiral mesh degassing and decontamination device; by adding a guide plate inside, the water flow direction is changed so that the inlet and outlet water directions are perpendicular to the water flow direction inside the inner cavity. At the same time, it adopts dual filtration of a first spiral mesh and a second spiral mesh, making better use of the function of the guide plate, increasing the filtration area and improving the filtration effect.

[0004] However, the existing technology has the following drawbacks: when the impurity content in the water is too high or there are specific viscous impurities (such as fine silt, algae, oily substances or fibers), the filter screen will be severely clogged during the filtration process. These impurities are easy to adhere to the filter screen and are difficult to shake off by micro-vibration, resulting in a sharp increase in equipment pressure drop and a sharp decrease in flow. The machine can only be stopped to clean the filter screen, which significantly affects the efficiency of the spiral degassing and descaling device. Summary of the Invention

[0013] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: By incorporating a filtration mechanism, when excessive impurities adhere to the filter element structure and cannot be cleaned by vibration, the piston rings are moved downwards using a telescopic component, causing rods a to rotate rapidly and move away from each other, thus disassembling the filter element structure. The liquid then washes away the adhered impurities, and the diversion section changes the liquid flow direction to discharge the washed-away impurities. Afterwards, the filter element structure is reassembled and restored, achieving a self-cleaning function of the filter element structure without stopping the machine. This significantly improves the cleaning efficiency and eliminates the need for manual cleaning by staff, reducing their workload. Attached Figure Description

[0016] Example 1, as Figures 1-5 As shown, the present invention proposes a spiral degassing and decontamination device, comprising a tank body 1, a top cover 2 detachably connected to the top of the tank body 1 (the top cover 2 is provided with lifting lugs for easy disassembly of the top cover 2, and also for easy lifting of the tank body 1 using the top cover 2); an automatic exhaust valve 4 is provided on the top cover 2 (this is prior art, and its specific structure and working principle will not be described in detail here); a bottom cover 3 detachably connected to the bottom of the tank body 1; a drain valve 13 is provided at the bottom of the bottom cover 3 (this is prior art, and its specific structure and working principle will not be described in detail here); a support leg 8 is connected to the bottom of the bottom cover 3 for supporting it on the ground; a water inlet pipe 5 is connected to the tank body 1; aligned circular openings a are provided on the tank body 1, the outer pipe 9, and the inner pipe 14; a water outlet pipe 6 is connected to the circular openings a; and a flow guiding mechanism and a filtration mechanism are also included. The flow guiding mechanism includes an outer pipe 9, an inner pipe 14, a flow divider, plate a15, plate b16, and a spiral guide vane 10. The outer pipe 9 is located inside the tank 1 (the outer pipe 9 is connected to the inner wall of the tank 1 by a support rod or other structure). The spiral guide vane 10 is connected to the outer surface of the outer pipe 9, and its four edges are connected to the inner wall of the tank 1. The inner pipe 14 is located inside the outer pipe 9 (a flow velocity sensor (including but not limited to an ultrasonic flow sensor) is provided near the bottom of the inner pipe 14 to monitor the flow velocity of the liquid inside the inner pipe 14). Plate a15 is detachably connected to the top of the outer pipe 9 and the inner pipe 14. Plate b16 is detachably connected to the bottom of the outer pipe 9 and the inner pipe 14 (by removing plates a15 and b16, it is convenient to maintain the telescopic component 17 and piston ring 18 inside the outer pipe 9). An opening is provided at the center of plate b16. The flow divider is located inside the inner pipe 14 to change the direction of water flow. The filtration mechanism includes a telescopic component 17, a piston ring 18, a traction rope 20, a rod a25, a rod b11, and a plate c22; a chamber is formed between the outer tube 9 and the inner tube 14; the telescopic component 17 is disposed on the inner wall of the chamber (the telescopic component 17 includes, but is not limited to, devices such as cylinders); the piston ring 18 is slidably disposed in the chamber (the piston ring 18 is made of polyurethane rubber, and it is mutually squeezed and sealed with the inner wall of the chamber; the piston ring 18 can prevent water from contacting the telescopic component 17 and the motor 19 when it enters the chamber through the holes); the telescopic component 17 is connected to the piston ring 18; multiple circumferentially distributed holes are opened on the plate b16 (the edges of the holes are rounded to avoid damage to the surface of the traction rope 20); multiple traction ropes 20 are provided and pass through the holes and are connected to one end of the rod a25 (traction... Rope 20 is a steel wire rope with high strength, wear resistance and corrosion resistance. A counterweight is connected to rod a25 near the traction rope 20 to facilitate the rotation of rod a25 and promote the disintegration of the filter element structure. Plate c22 is located below plate b16 and is connected to plate b16 through rod c21. Plate c22 has multiple circumferentially distributed grooves. The other end of rod a25 is rotatably connected to the grooves. Multiple rods b11 are provided and are evenly distributed on rod a25. The length of rod b11 gradually decreases from top to bottom. Multiple rods a25 and rods b11 converge to form the filter element structure (rod b11 is an arc-shaped rod. When rods a25 and rods b11 converge, the ends of adjacent rods b11 contact each other, so that rods a25 and rods b11 can form a conical mesh structure).

[0017] In this embodiment, the mixed liquid (a mixture of gas, impurities, and water) is introduced into the tank 1 through the water inlet pipe 5. Under the guidance of the spiral guide vanes 10, the mixed liquid flows in a spiral. As the cross-sectional area of ​​the liquid flow channel suddenly expands, the liquid flow rate decreases sharply. At the same time, the liquid collides and rubs violently with the inner wall of the flow channel, causing the internal pressure to drop. The solubility of water for gas also decreases, causing the microbubbles that were originally dissolved or suspended in the water to be rapidly precipitated, released, and aggregated into larger bubbles. Since the density of gas is much smaller than that of water, these bubbles will quickly float to the top of the equipment and eventually be discharged through the automatic exhaust valve 4.

[0018] When the liquid flows to the bottom of the tank 1, it passes through the filter element structure. Impurities in the liquid are blocked and filtered by the filter element and settle into the bottom cover 3. The filtered liquid enters the inner tube 14 and is discharged through the outlet pipe 6. If viscous impurities (such as fine silt, algae, oily substances, or fibers) in the mixed liquid adhere to the surface of the filter element and cannot be removed by vibration, they will significantly reduce the effective filtration area of ​​the filter element. This will cause the liquid flow rate inside the inner tube 14 to decrease significantly. When the flow rate sensor detects that the flow rate inside the inner tube 14 has decreased beyond the threshold, it will send feedback to the external controller. The external controller will first control the diversion part to change the liquid flow direction so that the liquid can be discharged through the diversion pipe 7. Then, the external controller will control the telescopic component 17 to work. The telescopic component 17 drives the piston ring 18 to move down. At the same time, under the action of the counterweight on the rod a25, the rod a25 rotates rapidly and moves away from each other, thereby causing the filter element structure to disintegrate rapidly. At this time, the impurities blocked by the filter element structure will be released from the filter element structure under the impact of the liquid and pass through the outlet pipe 6. The liquid is drained through the diversion pipe 7. Then, the external controller controls the telescopic component 17 to work again and drive the piston ring 18 to move upward (the external controller controls the disassembly time of the filter element structure. During this time, most of the impurities blocked on the filter element structure will be flushed away. After the time is up, the filter element structure will automatically reassemble and restore itself). The traction rope 20 pulls the rods a25 at various points to rotate and move them closer together, which in turn drives the rods b11 to move closer together. When the ends of adjacent rods b11 contact each other, rods a25 and b11 form the filter element structure again to filter the mixed liquid. After the set time is reached (during this time, the impurity content in the liquid discharged from the diversion pipe 7 will gradually approach zero, preventing unfiltered liquid in the inner pipe 14 from being discharged through the outlet pipe 6), the external controller controls the diversion part to change the liquid flow direction, so that the liquid is discharged through the outlet pipe 6 again. Thus, the self-cleaning function of the filter element structure is realized without stopping the machine, which significantly improves the cleaning efficiency and eliminates the need for manual cleaning by the staff, reducing the workload of the staff.

[0019] Example 2, as Figure 5As shown, the spiral degassing and decontamination device proposed in this invention, compared with Embodiment 1, further includes a hanging rope 23 connected to the rod a25; the bottom end of the hanging rope 23 is connected to a vibrating ball 24, which is composed of a metal ball and a rubber shell (the rubber shell is made of corrosion-resistant rubber, including but not limited to polyurethane rubber, which has good tear resistance, wear resistance and corrosion resistance; the metal ball can increase the weight of the vibrating ball 24 and enhance its impact force); the rubber shell wraps around the outside of the metal ball to play a buffering role.

[0020] In this embodiment, when the liquid flows to the bottom of the tank 1, it impacts the vibrating ball 24, causing the vibrating ball 24 to continuously strike the filter element structure, which causes the filter element structure to vibrate. This helps impurities to detach from the filter element structure, thereby reducing the probability of impurities adhering to the filter element structure.

[0021] Example 3, as Figures 6-7 As shown, the spiral degassing and decontamination device proposed in this invention, compared with Embodiment 2, further includes a diversion section, which includes a sphere 12, a motor 19, a sealing seat, and a diversion pipe 7; the sealing seat is connected to the inner wall of the inner tube 14; the inner wall of the sealing seat has an arc-shaped groove; the sphere 12 is rotatably disposed in the spherical groove (the surface of the sphere 12 and the inner wall of the arc-shaped groove are provided with a nitrile rubber layer, which is a commonly used and excellent material in sliding seals, with the advantages of wear resistance, oil resistance, and high cost-effectiveness, ensuring the sliding sealing function between the sphere 12 and the sealing seat); the inside of the sphere 12 has a direct flow groove 1201 and a side flow groove 1202 communicating with the direct flow groove 1201; the tank 1, the outer tube 9, the inner tube 14, and the sealing seat have aligned circular openings b; the diversion pipe 7 is connected inside the circular opening b; the motor 19 is disposed inside the chamber and its output end is connected to the sphere 12.

[0022] In this embodiment, when the filter element structure is functioning normally, the direct current channel 1201 is kept parallel to the inner tube 14, so that the filtered liquid can pass through the direct current channel 1201 and finally be discharged through the outlet pipe 6. When it is necessary to unclog the filter element structure, the motor 19 is first controlled by the external controller to work. The motor 19 drives the ball 12 to rotate, so that the side flow channel 1202 is downward. At the same time, one end of the direct current channel 1201 is aligned with the diversion pipe 7. At this time, the mixed liquid will carry the flushed impurities through the direct current channel 1201 and the side flow channel 1202 into the diversion pipe 7, and then be discharged through the diversion pipe 7, realizing the self-unclogging function of the filter element structure.

[0023] It is worth noting that the diameters of the DC channel 1201 and the side flow channel 1202 are much larger than the pore diameter of the filter element structure, so they will not be blocked by impurities in the liquid when the filter element structure is disassembled.

[0024] The electronic devices in this invention are all controlled by external controllers (including but not limited to PLC controllers) to operate in an orderly manner.

[0025] In summary, the mixed liquid (a mixture of gas, impurities, and water) is introduced into the tank 1 through the inlet pipe 5. Under the guidance of the spiral guide vanes 10, the mixed liquid flows in a spiral. Due to the sudden expansion of the cross-sectional area of ​​the liquid flow channel, the liquid flow rate decreases sharply. At the same time, the liquid collides and rubs violently with the inner wall of the flow channel, causing the internal pressure to drop. The solubility of water for gas also decreases, causing the microbubbles that were originally dissolved or suspended in the water to be rapidly precipitated, released, and aggregated into larger bubbles. Since the density of gas is much smaller than that of water, these bubbles will quickly float to the top of the equipment and eventually be discharged through the automatic exhaust valve 4.

[0026] When the liquid flows to the bottom of the tank 1, it passes through the filter element structure. Impurities in the liquid are blocked and filtered by the filter element and settle into the bottom cover 3. At the same time, the liquid impacts the vibrating ball 24, causing the vibrating ball 24 to continuously strike the filter element structure, making the filter element structure vibrate. This helps impurities to detach from the filter element structure, thereby reducing the probability of impurities adhering to the filter element structure. The filtered liquid enters the inner tube 14 and is discharged through the outlet pipe 6. If viscous impurities (such as fine silt, algae, oily substances, or fibers) in the mixed liquid adhere to the surface of the filter element and cannot be removed by vibration, it will significantly reduce the effective filtration area of ​​the filter element. This results in a significant decrease in the liquid flow velocity inside the inner tube 14. When the flow velocity sensor detects that the decrease in the flow velocity inside the inner tube 14 exceeds a threshold, it will send feedback to the external controller. The external controller will first control the motor 19 to work, which will drive the ball 12 to rotate, causing the side flow channel 1202 to move downward. At the same time, one end of the direct flow channel 1201 will be aligned with the diversion pipe 7 to change the liquid flow direction, allowing the liquid to be discharged through the diversion pipe 7. After that, the external controller will control the telescopic component 17 to work, which will drive the piston ring 18 to move downward. At the same time, under the action of the counterweight on the rod a25, the rod a25 will rotate rapidly and move towards the opposite direction. The impurities trapped by the filter element structure are disintegrated rapidly due to the impact of the liquid. These impurities are then removed from the filter element structure by the liquid's impact and discharged through the diversion pipe 7. Subsequently, the external controller controls the telescopic component 17 to work again, causing the piston ring 18 to move upwards (the external controller controls the disintegration time of the filter element structure; within this time, most of the impurities trapped on the filter element structure are flushed away, and the filter element structure automatically reassembles after the time is up). The traction rope 20 pulls the rods a25 at various points to rotate and move them closer together, thereby causing the rods b11 to move closer together. When the ends of adjacent rods b11 contact each other... Rods a25 and b11 then form a filter element structure to filter the mixed liquid. After a set time (during which the impurity content in the liquid discharged from the diversion pipe 7 gradually approaches zero, preventing unfiltered liquid in the inner pipe 14 from being discharged through the outlet pipe 6), the external controller controls the motor 19 to work again, causing the ball 12 to rotate and keep the DC groove 1201 parallel to the inner pipe 14, so that the liquid is discharged through the outlet pipe 6 again. Thus, the filter element structure achieves self-cleaning function without stopping the machine, significantly improving the cleaning efficiency, and eliminating the need for manual cleaning by staff, reducing the workload of staff.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
