Description
Technical Field
[0001] This application relates to the field of pipeline cleaning technology, and in particular to an ozone pipe inner wall descaling device. Background Technology
[0002] Ozone, as a strong oxidant, occupies an irreplaceable position in modern industrial systems. According to existing research, ozone is widely used in drinking water disinfection, advanced industrial wastewater treatment, pulp bleaching, and cooling circulating water treatment. Compared with traditional chlorine agents, ozone has a higher oxidation potential, which can rapidly destroy the cell walls of bacteria, inactivate viruses (such as Legionella), and effectively degrade recalcitrant organic pollutants.
[0003] Ozone gas scaling on the inner walls of pipes is a common and troublesome problem. These scales are usually composed of metal oxides, calcium and magnesium deposits, and organic and inorganic impurities. They are hard and tightly attached. Regular cleaning is a necessary measure to ensure ozone concentration, pipe flow and safe operation of the system. However, traditional mechanical scraping type pipes use rigid or semi-rigid structures with a fixed diameter. When encountering uneven scale thickness or local diameter reduction inside the pipe, they are very easy to get stuck. Summary of the Invention
[0004] To address the issue of easy jamming in scraping structures, this application provides an ozone pipeline inner wall descaling device.

The water flow drives the turbine and reciprocating screw to rotate, eliminating the need for any motor, battery or circuit, thus achieving "explosion-proof" safety and fundamentally eliminating the hidden danger of accidents caused by electric sparks. The cleaning mechanism and scraper achieve adaptive mechanical scraping based on this power.
[0007] Preferably, the moving device includes a fixing ring disposed on the outer surface of the main cylinder, and a plurality of connecting rods are disposed on the outer surface of the fixing ring, and a roller is disposed on the side of the connecting rod away from the fixing ring, which is in contact with the inner wall of the pipe.
[0008] By adopting the above technical solution, the fixed ring serves as the mounting base, the connecting rod provides hinge and elastic support, and the roller at its end rolls tightly against the pipe wall under the action of the torsion spring, together realizing the guidance, stability and drag reduction of the device.
[0009] Preferably, the auxiliary mechanism includes an auxiliary cylinder disposed inside the main cylinder, the auxiliary cylinder having a cavity inside, the side of the auxiliary cylinder being rotatably disposed with the turbine, the drive shaft being rotatably disposed inside the auxiliary cylinder, and the auxiliary cylinder having a drive device for squeezing out water flow inside.
[0010] By adopting the above technical solution, the auxiliary cylinder and its internal cavity constitute a chamber for water flow storage and conversion. Its rotational connection with the turbine and the through-running of the drive shaft enable uninterrupted power transmission from the turbine to the internal drive device.
[0011] Preferably, the driving device includes a reciprocating lead screw fixedly mounted on the outer surface of the drive shaft, guide columns symmetrically arranged inside the auxiliary cylinder, a nut mounted on the outer surface of the reciprocating lead screw, a piston plate slidably mounted on the outer surface of the guide column on the outer surface of the nut, and a bellows sleeved on the outer surface of the reciprocating lead screw between the two sides of the piston plate and the inner wall of the auxiliary cylinder.
[0012] By adopting the above technical solution, the reciprocating screw transforms the rotational motion of the drive shaft into the core drive form, the guide column ensures that the piston plate moves linearly without deflection, the nut is the key component for motion conversion, the piston plate performs reciprocating motion to squeeze the water flow, and the bellows provides dynamic sealing and adapts to changes in piston stroke.
[0013] Preferably, the cleaning mechanism includes a rotating disk one disposed on the side of the main body cylinder away from the connecting seat, a sliding groove is provided on one side of the main body cylinder, and a rotating disk two is disposed on the side of the sliding groove away from the main body cylinder, and a plurality of telescopic devices are provided on the outer surfaces of the rotating disk one and the rotating disk two.
[0014] By adopting the above technical solution, the first rotating disk serves as the active rotating component to input power, the slide groove provides a sliding path for the connecting components, and the second rotating disk serves as the fixed end to provide a reverse support point. Together, they drive the scraper movement through multiple telescopic devices.
[0015] Preferably, the telescopic device includes a fixed cylinder disposed on the outer surface of the first rotating disk and the second rotating disk, a movable column slidably disposed inside the fixed cylinder, the scraper being disposed on the side of the movable column away from the fixed cylinder, and a connecting device being disposed on the side of the movable column close to the main cylinder.
[0016] By adopting the above technical solution, the fixed cylinder provides a sliding track for the moving column and transmits rotation. The moving column, as a moving part that directly carries the scraper and performs radial extension and retraction, has a connecting device at its end that enables floating connection and elastic reset with the main cylinder.
[0017] Preferably, the connecting device includes a universal joint one disposed on the side of the moving column near the main body cylinder, a universal joint two disposed inside the sliding groove, a cylinder one disposed on the side of the universal joint two near the universal joint one, a sliding column slidably disposed inside the cylinder one disposed on the side of the universal joint one near the cylinder one, and a return spring disposed between the sliding column and the cylinder one.
[0018] By adopting the above technical solution, universal joint one and universal joint two together allow the scraper assembly to swing in multiple directions under complex working conditions to adapt to the pipe wall. Cylinder one and sliding column form a telescopic guide pair, and the return spring provides the elastic force to retract the scraper and forms a dynamic balance with the centrifugal force.

[0021] Preferably, the drain pipe is inclined at an angle of 30 degrees.
[0022] By adopting the above technical solution, the key geometric parameters of the drainage pipe were clarified. Its 30-degree tilt angle was optimized to precisely guide the water flow to the turbine blades, so as to most effectively convert the impact force of the water flow into the rotational torque of the turbine.
[0023] Preferably, the auxiliary cylinder is composed of a first circular plate and a second circular plate, and the length of the second circular plate is one-third the length of the first circular plate. The longer side of the first circular plate in the auxiliary cylinder is located away from the turbine.
[0024] By adopting the above technical solution, the detailed features of the auxiliary cylinder are supplemented. Its asymmetrical design, consisting of two circular plates of different lengths, is designed to form an inlet at a specific location to effectively collect part of the water flow after passing through the turbine.
[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By using water flow to drive the turbine and reciprocating screw, without the need for any motor, battery or circuit, it achieves "explosion-proof" safety in a confined pipe space rich in ozone and containing flammable gases, fundamentally eliminating the hidden danger of accidents caused by electric sparks.
[0026] 2. The scraper is controlled by a dynamic balance system of centrifugal force and return spring. It can automatically adjust the scraping force according to the hardness of the scale. When the scale is soft, the speed is high, the centrifugal force is large, and the scraping force is strong. When encountering hard scale, the resistance increases, the speed decreases, and the scraper automatically retracts, effectively avoiding jamming. This is an extremely reliable "mechanical intelligence" that relies on physical laws.
[0027] 3. By achieving simultaneous composite cleaning of "hydraulic flushing + mechanical scraping", a portion of the water flow driven by the turbine is directed to the auxiliary cylinder, pressurized by the piston plate, and sprayed out in a directional high pressure from the nozzle to pre- or simultaneously flush and soften the scale layer. Then, the rotating scraper scrapes and removes the loosened scale. The two work together, and the efficiency is far higher than that of a single method. Attached Figure Description

Detailed Implementation
[0030] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.
[0031] This application discloses an ozone pipeline inner wall descaling device.
[0032] Reference Figures 1-3 An ozone pipeline inner wall descaling device includes a main cylinder 1. A moving device is provided on the outer surface of the main cylinder 1 to assist the movement of the main cylinder 1. The moving device includes a fixed ring 2, which is fixedly connected to the outer surface of the main cylinder 1. Several connecting rods 21 are symmetrically hinged to the outer surface of the fixed ring 2. A torsion spring is fixedly connected between the connecting rods 21 and the fixed ring 2, so that the connecting rods 21 are in an outward expansion state. A roller 22 is rotatably connected to the end of the connecting rod 21 away from the fixed ring 2. The roller 22 is in contact with the inner wall of the pipeline. An auxiliary mechanism 4 is installed inside the main body cylinder 1 to collect water flow. Several nozzles 5 are fixedly connected and connected to the outer surface of the main body cylinder 1. These nozzles 5 are used for spraying water and are arranged in a circular array. The nozzle openings of the nozzles 5 are small, allowing for the spraying of dirt from the inner wall of the pipe. A connecting seat 3 is fixedly connected to the side of the main body cylinder 1 away from the nozzles 5. An inlet pipe 31 is fixedly connected and connected inside the connecting seat 3. Several drain pipes 32 are fixedly connected and connected inside the main body cylinder 1. The pipes 32 are arranged in a circular array and the drain pipes 32 are inclined at an angle of 30 degrees. The turbine 33 is rotatably connected inside the main body cylinder 1. The drain pipes 32 are directly opposite the blades of the turbine 33. A drive shaft 34 is fixedly connected to the center of the inner wall of the turbine 33. The drive shaft 34 is rotatably connected to the inner wall of the main body cylinder 1. A cleaning mechanism 6 is provided on one side of the main body cylinder 1. The cleaning mechanism 6 is used for adaptive adjustment. A scraper 7 for descaling is provided at the moving end of the cleaning mechanism 6. The scraper 7 is arc-shaped and the contact surface with the pipe wall is designed with a wave pattern.
[0033] First, place the main body cylinder 1 into the inlet of the ozone pipe to be cleaned, ensuring that the rollers 22 on it are in contact with the inner wall of the pipe. Then, reliably connect the external water supply pipe to the inlet pipe 31 on the device connection seat 3. Then, open the water supply valve, and the high-pressure water flows into the main body cylinder 1 through the inlet pipe 31 and is sprayed forward through the inclined drain pipes 32 arranged in a circular array. The drain pipes 32 guide the water flow precisely to the blades of the turbine 33 at an angle of about 30 degrees. The reaction force generated by the water flow impact drives the turbine 33 to start rotating at high speed. The rotation of the turbine 33 is converted into the core power of the entire device through its central drive shaft 34. At the same time, the water flow impact also drives the main body cylinder 1 to start moving along the pipe axis. The rollers 22 on its outside roll tightly against the pipe wall under the action of the torsion spring, playing a role in assisting movement and stabilizing guidance. When the turbine 33 rotates, the drive unit enters the cleaning stage. Under the action of centrifugal force, the scraper 7 opens outward, so that its wavy arc-shaped cutting edge closely adheres to the inner wall of the pipe. As the device moves forward and the scraper 7 rotates, mechanical scraping of the scale layer is achieved. On the other hand, a portion of the water flow after impacting the turbine 33 is introduced into the auxiliary mechanism 4 in the main cylinder 1, so that the water is pressurized and delivered to the nozzles 5 in the circumferential array to spray the inner wall of the pipe, which plays the role of pre-flushing, softening the scale layer and removing residual debris after scraping. This achieves the simultaneous operation of "mechanical scraping" and "hydraulic flushing".
[0034] After the work is completed, first close the water supply valve. After the water flow stops, the turbine 33 loses power and the speed drops rapidly. The centrifugal force on the scraper 7 disappears, minimizing the outer diameter of the device. Finally, the entire device can be easily pulled out or removed from the pipe, completing all the cleaning work. The entire process requires no electricity, is driven only by water pressure, and is safe, efficient and highly adaptable.
[0035] Reference Figures 4-5 The auxiliary mechanism 4 includes an auxiliary cylinder 41, which is fixedly connected to the inner wall of the main cylinder 1. The auxiliary cylinder 41 is composed of a circular plate 1 and a circular plate 2, and the length of the circular plate 2 is one-third of the length of the circular plate 1. The longer side of the circular plate 1 in the auxiliary cylinder 41 is located away from the turbine 33. A cavity 42 is opened inside the auxiliary cylinder 41. The side of the auxiliary cylinder 41 away from the nozzle 5 is rotatably connected to the turbine 33. The drive shaft 34 is rotatably connected through the auxiliary cylinder 41. A drive device is provided inside the auxiliary cylinder 41. The drive device is used to squeeze out the water flowing into the auxiliary cylinder 41. The drive device includes a reciprocating screw 43, which is fixedly connected to the outer surface of the drive shaft 34. A guide post 46 is symmetrically fixedly connected to the inner wall of the auxiliary cylinder 41 at an eccentric position. A nut 44 is slidably connected to the outer surface of the reciprocating screw 43. A ball bearing and a reversing device are provided inside the nut 44. A piston plate 45 is fixedly connected to the outer surface of the nut 44. The piston plate 45 is slidably connected to the outer surface of the guide post 46. Bellows 47 are symmetrically fixedly connected to both sides of the piston plate 45. The other side of the bellows 47 is fixedly connected to the inner wall of the auxiliary cylinder 41, and the bellows 47 is sleeved on the outer surface of the reciprocating screw 43.
[0036] When high-pressure water flows through the drain pipe 32 and impacts the turbine 33, driving it to rotate, the auxiliary mechanism 4 immediately begins to work in coordination. The rotation of the turbine 33 drives the drive shaft 34 at its center to rotate, and the reciprocating screw 43 fixed to the surface of the drive shaft 34 rotates synchronously. Due to the unique design of the auxiliary cylinder 41—the length of the circular plate 2 on the side near the turbine 33 is shorter, about one-third the length of the circular plate 1 on the other side—some of the water flow after impacting the turbine 33 can smoothly flow into the interior of the auxiliary cylinder 41 from the cavity 42 area on this side. The incoming water first fills the sealed chamber formed by the piston plate 45, the bellows 47 and the inner wall of the auxiliary cylinder 41. At this time, the rotating reciprocating screw 43 begins to play a core role. The nut 44, which forms a precision motion pair with the reciprocating screw 43 through the ball and the reverser, converts the rotational motion of the reciprocating screw 43 into its own linear reciprocating motion along the axis of the reciprocating screw 43. The piston plate 45, which is fixedly connected to the nut 44, slides smoothly and without rotation under the constraint of the guide post 46 passing through it. When the nut 44 drives the piston plate 45 to move away from the turbine 33, the piston plate 45 compresses the bellows 47 on that side and applies pressure to the water flow in the chamber. Due to the flexibility and sealing of the bellows 47, it can both deform with the piston plate 45 and effectively prevent water leakage. The pressurized water flow is forced to be ejected at high speed from the nozzles 5 in the circumferential array through the connecting pipe under the push of the piston plate 45. The small-diameter nozzles of the nozzles 5 further accelerate the water flow, forming multiple high-pressure jets with strong scouring effect, which act on the inner wall of the pipe. Subsequently, when the reciprocating screw 43 drives the nut 44 to move in the opposite direction, that is, when the piston plate 45 moves back towards the turbine 33, the original chamber volume increases and forms a negative pressure. On the one hand, this causes the subsequent water flow to continue to flow in from the cavity 42 to replenish the water, and on the other hand, it stretches the bellows 47 on the other side. This cycle repeats itself. The continuous rotation of the drive shaft 34 is transformed into the stable and periodic reciprocating motion of the piston plate 45 through the reciprocating screw 43, thereby transforming the continuous water flow into the auxiliary cylinder 41 into an intermittent pulse jet with significantly increased pressure, which is continuously ejected from the nozzle 5. Together with the mechanical scraping mechanism, it completes the composite cleaning of the scale on the inner wall of the pipe.
[0037] Reference Figures 6-8 The cleaning mechanism 6 includes a rotating disk 62, which is rotatably connected to the side of the main body cylinder 1 away from the connecting seat 3. The rotating disk 62 is coaxially connected to the drive shaft 34. A sliding groove 61 is provided on the side of the main body cylinder 1 near the rotating disk 62. A rotating disk 63 is fixedly connected to one side of the sliding groove 61. The rotating disk 63 is located on the side away from the main body cylinder 1. Several telescopic devices are provided on the outer surfaces of the rotating disk 62 and the rotating disk 63. The telescopic device includes a fixed cylinder 64, which is rotatably connected to the outer surfaces of rotating disk 1 62 and rotating disk 2 63. A movable column 65 is slidably connected inside the fixed cylinder 64, and a limiting block is fixed on the outer surface of the movable column 65. A limiting groove is opened inside the fixed cylinder 64 to prevent the movable column 65 from detaching from the fixed cylinder 64. A scraper 7 is fixedly connected to the side of the movable column 65 away from the fixed cylinder 64. A connecting device is provided on one side of the movable column 65, and the connecting device is located on the side close to the main body cylinder 1. The connecting device includes a universal joint 66, which is fixedly connected to the side of the moving column 65 near the main body cylinder 1. A universal joint 67 is slidably connected inside the slide groove 61. A cylinder 68 is fixedly connected to one side of the universal joint 67, which is located near the side of the universal joint 66. A sliding column 69 is fixedly connected to one side of the universal joint 66, which is located near the side of the cylinder 68 and is slidably connected inside the cylinder 68. A return spring 610 is fixedly connected to the side of the sliding column 69 near the cylinder 68, and the side of the return spring 610 away from the sliding column 69 is fixedly connected to the inner wall of the cylinder 68.
[0038] In the initial state, that is, when the device is not in operation with water, the turbine 33 and drive shaft 34 are stationary, and the rotating disk 62 does not rotate. At this time, the scraper 7 installed on the moving column 65 is pulled inward by the return spring 610 in the connecting device through the sliding column 69 in the cylinder 68, and finally the moving column 65 is mostly retracted into the fixed cylinder 64. The scraper 7 is close to the outer contour of the main body cylinder 1, and the radial dimension of the entire device is minimized, which makes it easy to put it into the pipeline. When the water flow begins, the water flow drives the turbine 33 to rotate at high speed. The power is transmitted to the rotating disk 62 through the drive shaft 34, causing it to rotate synchronously. The rotating disk 62 and the rotating disk 63 fixed on the main body cylinder 1 are both connected to the moving column 65 through the fixed cylinder 64. As the rotating disk 62 rotates, the entire telescopic device begins to revolve around the axis of the drive shaft 34, generating centrifugal force. This centrifugal force acts directly on the moving column 65 and the scraper 7, causing them to tend to move radially outward. When the rotation speed is high enough, the centrifugal force overcomes the preload of the return spring 610, pushing the moving column 65 to slide outward along the fixed cylinder 64. At the same time, the sliding column 69 is also pulled outward from the cylinder 68, further stretching the return spring 610. Finally, the scraper 7 expands outward until its wavy cutting edge tightly adheres to the inner wall of the pipe. With the axial movement of the device and the revolution of the rotating disk, the scale is effectively scraped off.
[0039] Among them, the scraper 7 is made of PTFE (Teflon), and the elastic element is made of Hastelloy or coated with Teflon, which avoids the risk of equipment disintegration due to material aging. The main body cylinder 1 is made of 316L stainless steel (coated with PTFE), which has excellent corrosion resistance and non-stick surface. The turbine 33 is made of Hastelloy to resist the dual corrosion of high-speed jet erosion and ozone oxidation. The connecting seat 3 adopts the standard DIN2576 ozone-grade quick-connect flange. After the device is placed into the pipe inlet, the connecting rod 21 is adjusted by the auxiliary support to ensure that the pre-tight compression of the roller 22 against the pipe wall is 3-5mm. When the operation is completed, the water supply is turned off, the internal pressure of the device is unloaded, and the return spring 610 pulls the scraper 7 back completely into the main body cylinder 1. The device can be easily pulled back by a winch using the traction ring reserved at the end of the water inlet pipe 31. Before the impurities (scale flakes, particles) scraped off by the scraper 7 have settled, they will be immediately flushed away from the pipe wall by the high-pressure pulse jets periodically ejected by the nozzle 5. These jets not only scour the working area of the scraper 7, but their backward tilting force can also push the impurities to the rear of the device. The device operates on the premise of a continuous water flow. This main water flow, which enters from the inlet pipe 31, drives the turbine 33, and is discharged from the front of the device, forms a stable, forward flow within the pipe. Impurities stirred up by the high-pressure jet are quickly carried away by this main water flow and transported to the treatment facilities downstream of the pipe, thus achieving a smooth and efficient cleaning process.
[0040] In the initial state, the return spring 610 pulls the scraper 7 inward. At this time, the outer diameter of the device is significantly smaller than the inner diameter of the pipe, and the device can easily pass through narrow or heavily sludged areas like ordinary fluid. Working state: When the turbine 33 is driven to rotate at high speed by the water flow, the scraper 7 opens outward under the action of centrifugal force to scrape against the spring force and adhere to the pipe wall. Adaptive feedback: If stubborn hard dirt is encountered, the resistance increases, the speed decreases, the centrifugal force decreases, the return spring 610 pulls the scraper 7 back, the cutting depth decreases, the resistance decreases, and the speed recovers; The return spring 610 in this device uses the calculation formula for alloy springs: F=kx, where F is the external force on the spring, k is the spring constant, N / m, and x is the deformation of the spring, m. The elastic force of the alloy spring is then calculated so that it can be used in this device. The return spring 610 in this device is made of 304 stainless steel wire.
[0041] The implementation principle of the ozone pipeline inner wall descaling device in this application embodiment is as follows: First, the device is placed into the pipe inlet and connected to the external water supply line. After the valve is opened, high-pressure water flows through the inclined drain pipe 32, impacting the blades of the turbine 33 and driving the turbine 33 to rotate at high speed. The resulting reaction force propels the entire device forward along the pipe. The rotation of the turbine 33 drives the drive shaft 34, which on the one hand drives the rotating disk 1 62 and rotating disk 2 63 to rotate. Under the action of centrifugal force, the scraper 7 overcomes the spring tension, opens outward, and adheres to the pipe wall for rotating scraping. On the other hand, the drive shaft 34 drives the reciprocating screw 43 to rotate, causing the nut 44 to drive the piston plate 45 to reciprocate. The turbine 33 converts a portion of the water flowing into the auxiliary cylinder 41 into a high-pressure pulse jet, which is then sprayed onto the pipe wall through the nozzle 5. When encountering hard scale that increases resistance, the scraper 7 rotates at a reduced speed and the centrifugal force weakens. The spring automatically pulls the scraper 7 back to reduce the cutting force and prevent jamming, thus achieving adaptive adjustment. After the operation is completed, the water supply is turned off, the turbine 33 stops rotating, the centrifugal force disappears, the spring fully retracts the scraper 7, and the device returns to its minimum outer diameter, making it easy to remove. The entire process is driven entirely by water pressure, requiring no electricity, and achieving automatic coordinated operation of scraping and rinsing.
