Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically to a microwave flue gas pipeline cleaning device. Background Technology

[0002] Microwave heating technology has been widely used in the field of comprehensive utilization and harmless treatment of resources containing organic solid waste (such as waste activated carbon, industrial waste salt, and chemical organic residues) due to its advantages such as bulk heating, selective heating, passive heating, and instant heating.

[0003] In existing technologies that use microwave heating to treat solid waste containing organic matter, the organic matter is decomposed under high temperatures and mixes with dust in the solid waste, forming high-temperature, oil- and gas-rich flue gas. This flue gas is then guided through flue gas ducts into dust removal equipment for preliminary purification and treatment.

[0004] However, because the flue gas contains a large amount of oil and gas and carries a high concentration of dust particles, these substances accumulate on the inner walls of the flue gas ducts during long-term operation, forming solid waste. Coking and ash accumulation can cause blockages in the flue gas ducts, severely impacting production efficiency. Utility Model Content

[0005] In view of this, the present invention provides a microwave flue gas duct cleaning device to solve the problem of solid waste accumulation in existing microwave flue gas ducts.

[0006] This utility model provides a microwave flue gas duct cleaning device, including: a first pipe, the lower end face of the first pipe is provided with a cleaning port, and the cleaning port is connected to the interior of the first pipe;

[0007] The driving component is configured on the first pipe;

[0008] The cleaning component is annular, with serrated edges at one or both ends along its axial direction. The axis of the cleaning component is collinear with the axis of the first pipe. The cleaning component is attached to the inner wall of the first pipe. The driving end of the driving assembly is connected to the cleaning component, and the driving assembly drives the cleaning component to reciprocate along the axial direction of the first pipe. The cleaning port is located on the moving path of the cleaning component.

[0009] By installing a cleaning component inside the first pipe and moving the cleaning component through a drive assembly, the annular cleaning component cleans the inner wall of the first pipe. This causes the scaled solids to be removed by the toothed component and then discharged from the cleaning port of the first pipe under the drive of the cleaning component, thereby improving the cleaning effect of the first pipe.

[0010] In one optional embodiment, the cleaning component is provided with serrated components at both ends of its axial direction, and a plurality of serrated components are provided along the circumference of the cleaning component.

[0011] By setting multiple serrated parts on the cleaning component, the serrated parts can clean the fixed waste from the inner wall of the first pipe during the movement of the cleaning component, and the cleaning effect on stubborn solid particles is better.

[0012] In one optional embodiment, the driving assembly includes: a driving member, a first rotating wheel, a second rotating wheel, and a transmission member. The driving member is disposed at one end of the first pipe along its axial direction, and the two ends of the transmission member along its length are respectively rotatably disposed on the first rotating wheel and the second rotating wheel. The first rotating wheel is connected to the driving end of the driving member, and the transmission member is connected to the dust removal member.

[0013] When the driving component drives the first rotating wheel to rotate, it drives the transmission component and the second rotating wheel to rotate, thereby driving the dust removal component to move.

[0014] By setting a drive assembly on the first pipe, the drive assembly is connected to the cleaning component through a transmission component, enabling the cleaning component to move precisely along the axial direction inside the first pipe. Since the cleaning component is attached to the inner wall of the first pipe, it can effectively scrape off the solid waste adhering to the inner wall of the pipe when it moves.

[0015] In one alternative embodiment, an elastic contraction device is provided on the first pipe, and the second rotating wheel is rotatably mounted on the elastic contraction device, the elastic contraction device having a force that drives the second rotating wheel to move away from the first rotating wheel.

[0016] Because the oil, gas and dust in the first pipeline are in a high-temperature and high-pressure environment, the transmission components are prone to thermal expansion and deformation under high temperature and pressure, which may cause the transmission components to loosen or fail. By setting an elastic contraction device, the second rotating wheel can maintain the tension of the transmission components when the transmission components expand and contract due to temperature changes, thereby ensuring the stable operation of the drive assembly.

[0017] In one optional embodiment, the elastic contraction device includes: a sliding member slidably disposed at one end of the first pipe along its axial direction, one end of the sliding member being rotatably connected to the second rotating wheel, the sliding direction of the sliding member being parallel to the extension direction of the first pipe, and an elastic member being disposed between the sliding member and the first pipe, the elastic member having a force that drives the second rotating wheel away from the first rotating wheel.

[0018] By incorporating a sliding element and an elastic element, the sliding element can slide axially on the first pipe, allowing the second rotating wheel to adaptively adjust according to the extension and retraction of the transmission component. The elastic element provides continuous tension, ensuring that the transmission component is always in a taut state.

[0019] In one optional embodiment, the sliding member is provided with a first bearing member, the second rotating wheel is rotatably mounted on the first bearing member, and the two sides of the second rotating wheel are provided with first sealing caps for sealing the first bearing member.

[0020] Alternatively, a second bearing component is provided on the first pipe, the first rotating wheel is rotatably mounted on the second bearing component, and second sealing caps for sealing the second bearing component are provided on both sides of the first rotating wheel.

[0021] By setting a first bearing component and a second bearing component, and setting a first sealing cover and a second sealing cover on both sides of the first bearing component and the second bearing component, oil and gas can be effectively prevented from entering the bearing, thus ensuring the stability of bearing operation and service life.

[0022] In one optional embodiment, the driving end of the driving member is rotatably connected to a driving shaft, the driving shaft passing through one end of the first pipe radially and exiting from the other end, and the first rotating wheel is disposed on the driving shaft.

[0023] By setting a drive shaft at the drive end of the drive component and mounting a first rotating wheel on the drive shaft, the drive shaft can drive the first rotating wheel to rotate, thereby driving the transmission component.

[0024] In one optional embodiment, at least one end of the drive shaft is provided with a rotary joint rotatably connected to the drive shaft, a cooling channel is provided inside the drive shaft, the rotary joint communicates with the cooling channel, and the rotary joint is used to connect a cooling device to introduce coolant into the cooling channel of the drive shaft.

[0025] By installing a rotary joint on the drive shaft and introducing coolant into the drive shaft through a cooling channel, continuous cooling is achieved during the operation of the drive shaft, thereby reducing the temperature of the drive shaft.

[0026] In one optional embodiment, a third bearing and a fourth bearing are provided on the first pipe, and the drive shaft is rotatably mounted on the third bearing and the fourth bearing. A first seal and a second seal are respectively provided on the side of the third bearing and the fourth bearing facing the first pipe.

[0027] By setting the first and second seals on the third and fourth bearing components, external impurities can be effectively prevented from entering the bearing. At the same time, the coolant flow in the cooling channel reduces the temperature of the drive shaft and cools the first and second seals, effectively preventing the seals from aging at high temperatures.

[0028] In one optional embodiment, the drive assembly is provided with a displacement detection assembly, which is used to detect the location of the dust removal component.

[0029] By setting up a displacement detection component to monitor the displacement of the drive shaft in real time, the specific position of the cleaning component inside the pipe can be accurately determined, thereby cleaning the first pipe more precisely. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0040] like Figure 1 , Figure 2 , Figure 3 As shown in the figure, according to an embodiment of the present invention, a microwave flue gas duct cleaning device is provided, comprising: a first duct 1, a driving assembly, and a cleaning component 2. The first duct 1 is a circular duct, and a cleaning port 3 is provided on the lower end face of the first duct 1, communicating with the interior of the first duct 1. The driving assembly is disposed on the first duct 1. The cleaning component 2 is annular, with serrated edges 4 at both ends along its axial direction. The axis of the cleaning component 2 is collinear with the axis of the first duct 1, and the cleaning component 2 abuts against the inner wall of the first duct 1. The driving end of the driving assembly is connected to the cleaning component 2, and the driving assembly drives the cleaning component 2 to reciprocate along the axial direction of the first duct 1. The cleaning port 3 is disposed on the moving path of the cleaning component 2. In the initial state, the cleaning component 2 is located at one end of the axial direction of the first duct 1. The driving assembly drives the cleaning component 2 to move towards the other end of the first duct 1. During the movement, the serrated edges 4 at the front end of the cleaning component 2 clean the waste material on the first duct 1, removing it during the movement. After the cleaning component 2 moves to the other end of the first pipe 1, the drive component drives the cleaning component 2 to retract, and pushes the waste material out of the cleaning port 3 during the retraction process.

[0041] By installing a cleaning component 2 inside the first pipe 1 and driving the cleaning component 2 to move, the annular cleaning component 2 cleans the inner wall of the first pipe 1, so that the scale solids are cleaned off by the action of the sawtooth component 4 and cleaned out of the inside of the first pipe 1 from the cleaning port 3 under the drive of the cleaning component 2, thereby improving the cleaning effect of the first pipe 1.

[0042] Specifically, the dust removal component 2 can also be installed only at one end in the axial direction.

[0043] Specifically, the first pipe 1 is inclined, and the cleaning port 3 is a cleaning pipe that is fixedly installed at the lower end of the first pipe 1 and extends downward. The end of the cleaning pipe is equipped with a sealing flange. The cleaning pipe is located at the lower end of the inclined section of the first pipe 1 to facilitate the smooth discharge of waste under the action of gravity.

[0044] The first pipe 1 is also equipped with an ascending pipe 5 and an exhaust pipe 6, which are vertically spaced apart and connected to the first pipe 1. Flue gas enters the first pipe 1 through the ascending pipe 5 and is discharged downwards by the exhaust pipe 6.

[0045] like Figure 4 As shown, in this embodiment, serrated parts 4 are provided at both ends of the axial direction of the cleaning component 2. Multiple serrated parts 4 are arranged circumferentially along the cleaning component 2. The serrated parts 4 are triangular in shape. During the movement of the cleaning component 2, the triangular tips of the serrated parts 4 can penetrate into the solid waste and remove it during the movement. By providing multiple serrated parts 4 on the cleaning component 2, the serrated parts 4 can remove the solid waste from the inner wall of the first pipe 1 during the movement of the cleaning component 2, resulting in better cleaning of stubborn solid particles. It should be noted that, as an alternative implementation, the upper end face of the serrated parts 4 can also be set as a guide angle. During the movement of the cleaning component 2, the guide angle can scoop into the bottom of the solid waste, lift and peel it off, improving cleaning efficiency.

[0046] like Figure 2 , Figure 3As shown, in this embodiment, the driving assembly includes: a driving component 7, a first rotating wheel 8, a second rotating wheel 9, and a transmission component 10. The driving component 7 is a motor, and the transmission component 10 is a steel chain. The driving component 7 is located at one end of the first pipe 1 along its axial direction, on the outside of the first pipe 1. The transmission component 10 is located inside the first pipe 1, with its two ends rotatably mounted on the first rotating wheel 8 and the second rotating wheel 9 along its length, respectively. The first rotating wheel 8 is connected to the driving end of the driving component 7, and the transmission component 10 is connected to the cleaning component 2. When the driving component 7 drives the first rotating wheel 8 to rotate, it drives the transmission component 10 and the second rotating wheel 9 to rotate, thereby moving the cleaning component 2. When the motor drives the first rotating wheel 8 to rotate, the chain moves, thereby moving the cleaning component 2, allowing the cleaning component 2 to clean the inner wall of the first pipe 1. By installing a drive assembly on the first pipe 1, which is connected to the cleaning component 2 via a transmission component 10, the cleaning component 2 can precisely reciprocate axially inside the first pipe 1. Since the cleaning component 2 is attached to the inner wall of the first pipe 1, it can effectively scrape away solid waste adhering to the inner wall of the pipe as it moves. It should be noted that, as an alternative implementation, the transmission component 10 can also be a chain made of iron.

[0047] Specifically, the cleaning component 2 is a ring-shaped circular structure. Serrated edges 4 are provided at both ends of the cleaning component 2 along its axial direction. A cylinder 11 is located at the center of the cleaning component 2, and the cylinder 11 is fixedly connected to the inner wall of the cleaning component 2 via connecting rods 12. The connecting rods 12 are evenly distributed along the circumference of the cylinder 11. Two pull rods 13 are provided at both ends of the cylinder 11 along its axial direction. One end of each pull rod 13 is threaded to the cylinder 11, and the other end is connected to a chain. Bolts pass through the pull rods 13 and then through the holes in the chain, and are then tightened with nuts for fixation, thereby achieving the connection and fixation between the cleaning component 2 and the transmission component 10.

[0048] like Figure 1 As shown, in this embodiment, an elastic contraction device is provided on the first pipe 1, and the elastic contraction device is located at the end of the first pipe 1 away from the drive assembly. The second rotating wheel 9 is rotatably mounted on the elastic contraction device, and the elastic contraction device has a force that drives the second rotating wheel 9 to move away from the first rotating wheel 8. Since the oil, gas, and dust in the first pipe 1 are in a high-temperature and high-pressure environment, the transmission component 10 is prone to thermal expansion and deformation under high temperature and high pressure, which may cause the transmission component 10 to loosen or fail. By providing the elastic contraction device, the second rotating wheel 9 can maintain the tension of the transmission component 10 when the transmission component 10 expands and contracts due to temperature changes, thereby ensuring the stable operation of the drive assembly. It should be noted that, as an alternative implementation, the drive assembly and the first rotating wheel 8 can also be mounted on the elastic contraction device.

[0049] like Figure 1As shown, in this embodiment, the elastic contraction device includes a sliding member 14 and an elastic member 15. The sliding member 14 is a cylindrical rod-shaped structure. The sliding member 14 is slidably disposed at one end of the first pipe 1 along its axial direction, and one end of the sliding member 14 is rotatably connected to the second rotating wheel 9. Two sliding members 14 are symmetrically arranged on both sides of the second rotating wheel 9, and a rotating shaft is fixedly disposed between the two sliding members 14. A first bearing member 16 is disposed on the rotating shaft, and the second rotating wheel 9 is rotatably disposed on the first bearing member 16. The sliding direction of the sliding member 14 is parallel to the extension direction of the first pipe 1. An elastic member 15, which is a spring, is disposed between the sliding member 14 and the first pipe 1. A circular plate with a diameter larger than that of the elastic member 15 is disposed on the sliding member 14. The circular plate extends outward along the radial direction of the sliding member 14. One end of the elastic member 15 abuts against the circular plate, and the other end abuts against the end face of the first pipe 1. The elastic member 15 has a force that drives the second rotating wheel 9 away from the first rotating wheel 8. By configuring the sliding member 14 and the elastic member 15, the sliding member 14 can slide axially on the first pipe 1, allowing the second rotating wheel 9 to adaptively adjust according to the extension and retraction of the transmission member 10. The elastic member 15 provides continuous tension, ensuring that the transmission member 10 is always in a taut state. It should be noted that, as an alternative implementation, the elastic contraction device can also be configured as a tensioning wheel.

[0050] like Figure 1 , Figure 5As shown, in this embodiment, a first bearing component 16 is provided on the sliding member 14, and a second rotating wheel 9 is rotatably mounted on the first bearing component 16. First sealing covers 17 for sealing the first bearing component 16 are provided on both sides of the second rotating wheel 9. The first bearing component 16 is a bearing. The outer ring of the bearing is connected to the second rotating wheel 9, and the inner ring of the bearing is connected to the rotating shaft. The first sealing cover 17 is detachably connected to the second rotating wheel 9 by bolts, which pass through the first sealing cover 17 and connect to the second rotating wheel 9. The first sealing cover 17 has a clearance hole for avoiding the rotating shaft, and the diameter of the clearance hole is the same as the diameter of the rotating shaft. The first sealing cover 17 has a cylindrical 11-shaped structure with an opening at one end, allowing the first bearing component 16 to be installed into the opening of the first sealing cover 17. During installation, the second rotating wheel 9 is first installed onto the rotating shaft, and the first sealing covers 17 are installed on both sides of the second rotating wheel 9. At this time, the first sealing covers 17 are fitted onto the outside of the first bearing component 16, achieving a seal on the bearing. In addition, a second bearing component 18 is provided on the first pipe 1, and a first rotating wheel 8 is rotatably mounted on the second bearing component 18. Second sealing covers for sealing the second bearing component 18 are provided on both sides of the first rotating wheel 8. The structure and installation method of the second sealing covers are the same as those of the first sealing cover 17, and will not be described again in this embodiment. By providing the first bearing component 16 and the second bearing component 18, and providing the first sealing cover 17 and the second sealing cover on both sides of the first bearing component 16 and the second bearing component 18, oil and gas are effectively prevented from entering the bearing, ensuring the service life of the bearing. It should be noted that, as an alternative implementation, a sealing ring is provided between the first sealing cover 17 and the rotating shaft, and a sealing ring is also provided between the first sealing cover 17 and the second rotating wheel 9. A sealing ring is also provided between the second sealing cover and the rotating shaft.

[0051] like Figure 2 , Figure 3 As shown, in this embodiment, the driving component 7 is bolted to the first pipe 1. A driving shaft 19 is rotatably connected to the driving end of the driving component 7. The driving shaft 19 passes radially through one end of the first pipe 1 and exits from the other end. A first rotating wheel 8 is mounted on the driving shaft 19. By setting the driving shaft 19 at the driving end of the driving component 7 and mounting the first rotating wheel 8 on the driving shaft 19, the driving shaft 19 can drive the first rotating wheel 8 to rotate, thereby driving the transmission component 10. It should be noted that, as an alternative implementation, the driving end of the driving component 7 can also be configured as a roller, with the roller and the first rotating wheel 8 connected by a chain drive.

[0052] like Figure 3As shown, in this embodiment, at least one end of the drive shaft 19 is provided with a rotary joint 20 rotatably connected to the drive shaft 19, and the rotary joint 20 is provided with a conductive channel 21. When the drive shaft 19 rotates, the rotary joint 20 does not rotate because it is rotatably connected to the drive shaft 19. The rotary joint 20 is cylindrical 11-shaped, and the conductive channel 21 extends along the axial direction of the rotary joint 20, with one end connected to the cooling channel 22 and the other end connected to the cooling device. The cooling channel 22 passes through the drive shaft 19 from one end to the other axially. The rotary joint 20 is used to connect the cooling device to introduce coolant into the cooling channel 22 of the drive shaft 19. The cooling device is prior art and can be a water-cooled cooler or an evaporative cooler. Cooling water is introduced into the cooling channel 22, flowing in from one end of the drive shaft 19 and out from the other end, thereby cooling the drive shaft 19. The pipe head of the cooling device is connected to the rotary joint 20 by a thread. By installing a rotary joint 20 on the drive shaft 19 and introducing coolant into the drive shaft 19 through the cooling channel 22, continuous cooling is achieved during the operation of the drive shaft 19, reducing its temperature and extending its service life. It should be noted that, as an alternative implementation, the conduction channel 21 of the rotary joint 20 may not be straight, but rather bent at a right angle. In this case, one end of the conduction channel 21 is connected to the cooling channel 22, and the other end is connected to the cooling equipment's piping.

[0053] like Figure 3As shown, in this embodiment, a third bearing 23 and a fourth bearing 24 are provided on the first pipe 1. The drive shaft 19 is rotatably mounted on the third bearing 23 and the fourth bearing 24. A first seal 25 and a second seal 26 are respectively provided on the side of the third bearing 23 and the fourth bearing 24 facing the first pipe 1. The first seal 25 and the second seal 26 seal the gap between the drive shaft 19 and the first pipe 1, preventing high-temperature flue gas from leaking from the inside of the first pipe 1 to the outside. The first seal 25 and the second seal 26 are made of rubber, which is prone to deterioration at high temperatures, resulting in poor sealing performance. When the coolant in the cooling channel 22 flows, it cools the drive shaft 19, and the coolant in the drive shaft 19 can cool the first seal 25 and the second seal 26, thereby improving the service life of the first seal 25 and the second seal 26. By providing a first seal 25 and a second seal 26 on the third bearing component 23 and the fourth bearing component 24, external impurities can be effectively prevented from entering the bearing interior. Simultaneously, the coolant flow within the cooling channel 22 lowers the temperature of the drive shaft 19 while simultaneously cooling the first seal 25 and the second seal 26, effectively preventing aging of the seals at high temperatures. It should be noted that, as an alternative implementation, the cooling device can also be equipped with two separate cooling pipes, spraying water onto the first seal 25 and the second seal 26 respectively.

[0054] like Figure 3 As shown, in this embodiment, a displacement detection component 28 is provided on the drive assembly. The displacement detection component 28 is used to detect the rotation distance of the drive shaft 19, thereby detecting the position of the cleaning component 2. By setting the displacement detection component 28 to monitor the displacement of the drive shaft 19 in real time, the specific position of the cleaning component 2 inside the pipe can be accurately determined, thereby cleaning the first pipe 1 more precisely.

[0055] Specifically, a pulley 27 is provided at the axial end of the drive shaft 19. The displacement sensor is a rope displacement sensor, which is a device that detects the displacement of an object by the linear motion of the rope. One end of the rope is mounted on the pulley 27, and the other end is connected to the displacement sensor. When the drive shaft 19 rotates, the pulley 27 rotates accordingly, driving the rope to move. The displacement sensor calculates the position of the cleaning component 2 based on the linear displacement change of the rope. The pulley 27 is fixedly mounted on the drive shaft 19.

[0056] Working principle: The annular cleaning component 2 is driven by the drive assembly to reciprocate axially along the first pipe 1. The cleaning component 2 is in contact with the inner wall of the pipe, and the serrated parts 4 at both ends of the component 2 penetrate and scrape off the solid waste adhering to the inner wall during the movement. The cleaned waste is pushed to the cleaning port 3 at the lower end of the pipe and discharged when the cleaning component 2 retracts. Coolant is introduced into the drive shaft 19 through the cooling channel 22 to reduce the impact of high-temperature flue gas on the shaft and seals.

[0057] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
