Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning, in particular to a dust cleaning device and an exhaust pipe which are convenient for cleaning an exhaust passage of a single crystal furnace. Background Art

[0002] In daily life, exhaust pipes are common pipe systems used to discharge waste gas, smoke or other gases. Exhaust pipes are usually connected to chimneys, exhaust fans or processing equipment to discharge the generated waste gas or smoke to a designated location or space, making it convenient for users to centrally handle waste gas.

[0003] The exhaust port of the single crystal furnace is an exhaust channel for discharging waste gas and smoke in the single crystal furnace. During the normal operation of the single crystal furnace, a large amount of waste gas will be generated. These waste gases need to be discharged through the exhaust port of the single crystal furnace. In order to ensure the effect of exhaust gas discharge and environmental protection, the exhaust port of the single crystal furnace needs to be cleaned and maintained regularly to prevent dust accumulation or blockage. However, when discharging these waste gases, smoke or other gases, they may be mixed with various dust, particles, fine substances or residual substances such as oily substances. When these waste gases pass through the exhaust pipe, the residues may adhere to the inner wall of the pipe. During the long-term use of the exhaust pipe, the residual substances are easy to accumulate on the inner wall of the pipe. As the flow rate of waste gas, smoke or other gases gradually increases, the residual substances attached to the inner wall of the pipe will also gradually increase. When the residual substances accumulate to a certain amount, they will form a larger volume on the inner wall of the pipe. The larger volume of residual substances will reduce the flow rate of the exhaust pipe and affect the exhaust efficiency. In severe cases, the exhaust pipe may even be blocked to cause safety hazards. In addition, it is not convenient to manually disassemble and clean the inside of the pipe, especially in the complex exhaust pipe structure with many bends. It is not easy to find and deal with it in time, affecting the use of the pipe.

[0004] In view of the above shortcomings, we need to develop a dust cleaning device and exhaust pipe that is convenient for cleaning the exhaust channel of the single crystal furnace to meet the needs of the majority of users. Utility Model Content

[0005] In view of the above-mentioned problem that residual substances are easily accumulated on the inner wall of the existing exhaust pipe and the interior of the pipe is not convenient for manual disassembly and cleaning, the technical solution adopted by the utility model to solve the technical problem is:

[0007] Furthermore, the driving rod includes a first driving rod for installing the cleaning component and a second driving rod for installing the scraper sleeve assembly, the driver drives the first driving rod to drive the cleaning component to perform linear reciprocating motion, and the driver drives the second driving rod to drive the scraper sleeve assembly to perform linear reciprocating motion.

[0008] Furthermore, the cleaning member adopts a hollow annular structure and is provided with a plurality of reinforcing ribs, and the middle portion of the cleaning member is fixedly connected to an end of the first driving rod away from the driver.

[0009] Furthermore, the cleaning cavity is divided into a plurality of areas at different positions by the reinforcing ribs, and a plurality of the scraping kits respectively pass through the cleaning cavity in corresponding advancing directions.

[0010] Furthermore, the cleaning chamber includes a first cleaning chamber, a second cleaning chamber and a third cleaning chamber separated by the reinforcing ribs, and the scraping kit includes a first scraping kit used in conjunction with the first cleaning chamber, a second scraping kit used in conjunction with the second cleaning chamber, and a third scraping kit used in conjunction with the third cleaning chamber.

[0011] Furthermore, a scraping blade structure is provided on a side of the scraping kit away from the driver, and the scraping blade structure is inclined from a side close to the cleaning chamber toward a middle portion of the scraping kit.

[0012] Furthermore, the scraper assembly is inclined and has an ash discharge cavity in the middle for facilitating ash discharge, and the support center of the ash cleaning component is close to the lower inclined side.

[0013] Furthermore, a plurality of the scraper kits are arranged at intervals around the circumference of the first driving rod, and the plurality of the scraper kits are all recessed toward the direction of the first driving rod.

[0016] The beneficial effects of the utility model are as follows:

[0017] 1. The utility model drives the cleaning piece and the scraper kit to be telescopically used in coordination through a driver, and can clean various dust, particles, fine substances or residual substances such as oily substances accumulated on the inner wall of the exhaust pipe. The cleaning piece scrapes the inner wall of the exhaust pipe and then passes through the scraper kit to clean the cleaning piece, thereby realizing the effect of automatic cleaning of the exhaust pipe wall and the self-cleaning function, and regularly cleaning the pipe wall without manual participation, thereby improving the cleaning efficiency and the convenience of cleaning.

[0018] 2.

[0024] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 4As shown, a cleaning device for cleaning the exhaust channel of a single crystal furnace comprises a cleaning piece 1, a scraper sleeve assembly 2 and a driver 3 for providing power, wherein the driver 3 is provided with a driving rod 30 for installing the cleaning piece 1 and the scraper sleeve assembly 2, and the driver 3 drives the driving rod 30 to drive the cleaning piece 1 and the scraper sleeve assembly 2 to reciprocate linearly, and the scraper sleeve assembly 2 comprises a scraper sleeve assembly 20 for cleaning the cleaning piece 1, and the cleaning piece 1 is provided with a cleaning cavity 10 for the scraper sleeve assembly 20 to reciprocate through.

[0026] Specifically, in some embodiments, the cleaning member 1 is a cleaning tool of the cleaning device mainly used to clean the residual materials accumulated on the exhaust pipe wall. The side of the cleaning member 1 away from the driver is designed with a thin wall. The thin wall design forms a sharp cutting thin wall, which makes it easier for the cleaning member 1 to cut and separate the residual materials accumulated on the exhaust pipe wall. After the residual materials are cut, they fall downward by natural gravity or are blown to a specified direction by the wind pressure circulating in the exhaust pipe. The cleaning member 1 is installed at the end of the driving rod 30 away from the driver 3. When the driver 3 is started, the driving rod 30 can push the cleaning member 1 to reciprocate along the inner wall of the exhaust pipe in a straight line, so that the cleaning member 1 can scrape the residual materials accumulated on the exhaust pipe wall. The scraped residual materials pass through the cleaning cavity 10 in the middle of the cleaning member 1 and fall and are discharged along the exhaust pipe wall, or are blown away by the wind pressure circulating in the exhaust pipe, thereby realizing the function of the cleaning device to clean the accumulated dust;

[0027] The scraper sleeve assembly 2 is a cleaning tool of the dust cleaning device mainly used for cleaning the inner side of the circular ring of the dust cleaning member 1. The scraper sleeve assembly 2 includes a plurality of scraper sleeves 20 arranged in a staggered manner, which can clean the dust accumulated at different positions on the dust cleaning member 1. The scraper sleeve 20 is installed at the end of the driving rod 30 away from the driving member 3. The dust cleaning member 1 is provided with a dust cleaning cavity 10 for the scraper sleeve 20 to pass through. After the dust cleaning member 1 cleans the dust, there may still be a part of the dust accumulated on the cavity wall of the dust cleaning cavity 10. This part of the dust accumulated can be cleaned by the scraper sleeve 20 freely inserted into the dust cleaning cavity 10 in the form of secondary scraping. The scraped residual material passes through the hollow scraper sleeve 20 and falls and is discharged along the exhaust pipe wall, or is blown away by the wind pressure circulating in the exhaust pipe, so as to realize the function of the dust cleaning device to clean its own dust, which is also called the self-cleaning function of the dust cleaning device;

[0028] The driver 3 is a driving device for providing movement power for the cleaning member 1 and the scraper kit 20. The driver 3 is provided with two driving rods 30 which are respectively connected to the cleaning member 1 and the scraper kit 20. The driving rod 30 connected to the cleaning member 1 drives the cleaning member 1 to make a linear reciprocating motion along the exhaust pipe wall. The driving rod 30 connected to the scraper kit 20 drives the scraper kit 20 to freely pass through the cleaning chamber 10 and make a linear reciprocating motion along the exhaust pipe wall. The driver 3 can independently control the driving rods 30 at different positions to extend and retract, so that when performing cleaning tasks, the driver 3 can use different driving rods 30 in a specific sequence to improve cleaning efficiency and shorten cleaning time.

[0029] More specifically, the cleaning device can be installed on the outer wall of the exhaust pipe with one end of the driver 3 facing the cleaning member 1 to fix the position of the cleaning device, and then the cleaning member 1 and the scraper kit 20 are inserted into the pipe of the exhaust pipe. After starting the cleaning device, the cleaning member 1 can make a scraping motion relative to the exhaust pipe wall through the driving rod 30 to clean the residual materials on the exhaust pipe wall, and the scraper kit 20 can make an interlacing motion relative to the cleaning member 1 through the driving rod 30 to clean the residual materials attached to the cleaning member 1.

[0030] More specifically, a clearance fit design is adopted between the cleaning piece 1 and the scraper kit 20. There is a small gap distance between the cleaning piece 1 and the scraper kit 20, so that when the scraper kit 20 repeatedly passes through the cleaning piece 1, it can not only scrape off the accumulated dust on the cleaning chamber 10, but also avoid collision with the cleaning piece 1. The gap distance between the cleaning piece 1 and the scraper kit 20 is controlled between 0-5mm, and the interlacing effect is better.

[0031] Specifically, in some embodiments, the driver 3 may use a motor transmission structure, a cylinder transmission structure or a hydraulic transmission structure as the main power source;

[0032] More specifically, the internal driving structure of the driver 3 can use a motor transmission structure as the main power source. The motor transmission structure usually has a high energy conversion efficiency and can effectively convert electrical energy into mechanical energy. The motor transmission structure can achieve precise control of mechanical equipment by accurately controlling the speed and torque of the motor. By adjusting the voltage, current or frequency of the motor, the output power can be accurately adjusted to meet the needs under different working conditions. The motor transmission structure can usually achieve smooth acceleration and deceleration during the start and stop process, reducing the impact and loss of traditional mechanical equipment and transmission structures. Compared with some mechanical transmission structures, the motor transmission usually has lower noise. The motor transmission structure does not generate harmful gases or waste during operation. Compared with some hydraulic or pneumatic transmission structures, the motor transmission structure is more environmentally friendly. The motor transmission structure has the characteristics of high efficiency, precise stroke, smooth start and stop, low noise, and convenient maintenance. It can be generally used in conventional exhaust pipes to clean up dust accumulation.

[0033] More specifically, the internal driving structure of the driver 3 can adopt a cylinder transmission structure as the main power source. The cylinder transmission structure is usually composed of basic components such as a cylinder, a piston, and an air valve. The structure is relatively simple. The cylinder transmission structure can quickly respond to the control signal, making the action quick and accurate, thereby improving work efficiency. Compared with hydraulic transmission, the cylinder transmission structure usually does not cause serious impact on the environment when it leaks, because gas leakage is relatively easy to handle. In addition, pneumatic components usually use non-compressible gases. Once a leak occurs, it will not cause the risk of accidental injury like a hydraulic system. The cylinder transmission structure has the characteristics of simple structure, low cost, easy operation and control, and low maintenance cost, and can be generally used in conventional exhaust pipes to clean dust accumulation.

[0034] More specifically, the internal driving structure of the driver 3 can adopt a hydraulic transmission structure as the main power source. The hydraulic transmission system can achieve different output powers and speeds by adjusting the working pressure and flow of the hydraulic components, thereby having high flexibility and adjustability. The hydraulic transmission structure can provide a large power output in a relatively small space, which makes it particularly advantageous when high power output is required but space is limited. When the accumulated residual material has a certain thickness, hardness and viscosity, it will produce a large resistance to removal. Therefore, the driver 3 adopting the hydraulic transmission structure can provide a greater thrust to remove the residual material with a certain resistance on the exhaust pipe wall. The hydraulic transmission structure can adapt to various working conditions and environmental requirements, including high temperature, high pressure, humidity and other harsh conditions. The hydraulic transmission structure can achieve smooth and continuous motion control, and can also provide high-precision position control and force control. The hydraulic transmission structure has the characteristics of stable transmission, large transmission thrust, and adaptability to harsh working environments. It can be used in special exhaust pipes to perform cleaning tasks of a certain difficulty.

[0035] like Figure 3 As shown, the driving rod 30 includes a first driving rod 31 for installing the cleaning component 1 and a second driving rod 32 for installing the scraper sleeve assembly 2, the driver 3 drives the first driving rod 31 to drive the cleaning component 1 to move linearly back and forth, and the driver 3 drives the second driving rod 32 to drive the scraper sleeve assembly 2 to move linearly back and forth.

[0036] Specifically, in some embodiments, the first driving rod 31 is a mounting support rod used by the driver 3 to drive the cleaning member 1 to move, and the second driving rod 32 is a mounting support rod used by the driver 3 to drive the scraper assembly 2 to move. The driver 3 can independently drive the first driving rod 31 and the second driving rod 32, respectively, and can control the cleaning member 1 to move back and forth along the exhaust pipe wall in a straight line before the scraper assembly 2 to scrape the dust accumulated on the exhaust pipe wall, and then control the scraper assembly 2 to move back and forth along the exhaust pipe wall in a straight line to scrape the dust accumulated on the cleaning member 1, so as to achieve smooth execution of pipe wall cleaning and self-cleaning;

[0037] More specifically, the extension length of the first drive rod 31 can be determined according to the length of the exhaust pipe that needs to be cleaned. The maximum extension length of the first drive rod 31 is sufficient for the cleaning component 1 to clean the entire straight line of the exhaust pipe wall. Generally, the extension length of the first drive rod 31 is greater than the extension length of the second drive rod 32. The extension length of the second drive rod 32 only needs to be sufficient for the scraper sleeve assembly 2 to smoothly pass through the cleaning chamber 10, that is, the extension length of the second drive rod 32 only needs to be sufficient for the scraper sleeve assembly 2 to smoothly pass through the cleaning component 1 when the first drive rod 31 is at its minimum extension length.

[0038] More specifically, the connection between the scraper sleeve assembly 2 and the second drive rod 32 is strengthened and the connection area is expanded by the connecting platform 27. The horizontal cross-sectional area of ​​the connecting platform 27 is larger than the horizontal cross-sectional area of ​​the second drive rod 32, so that the scraper sleeve assembly 2 can install multiple components on the connecting platform 27, avoiding the difficulty of installing multiple components of the scraper sleeve assembly 2 on the end of the second drive rod 32 away from the driver 3, thereby improving the stability of the connection structure.

[0039] like Figure 1 and Figure 4 As shown, the cleaning member 1 adopts a hollow annular structure and is provided with a plurality of reinforcing ribs 14 , and the middle portion of the cleaning member 1 is fixedly connected to an end of the first driving rod 31 away from the driver 3 .

[0040] Specifically, in some embodiments, the cleaning piece 1 adopts a hollow annular structure parallel to the radial plane of the exhaust pipe. The shape of the cleaning piece 1 can be set according to the cross-sectional tube type of the exhaust pipe. For example, a circular exhaust pipe adopts a circular cleaning piece 1, and an elliptical exhaust pipe adopts an elliptical cleaning piece 1. The shape of the cleaning piece 1 is designed by analogy. The hollow design can facilitate the smooth passage of the scraper kit 20. The hollow annular structure is connected to the middle part of the cleaning piece 1 through the reinforcing rib 14. The middle part of the cleaning piece 1 is fixedly connected to the end of the first drive rod 31 away from the driver 3, so that when the cleaning piece 1 is pushed by the first drive rod 31, it will not produce a circular rotation relative to the first drive rod 31, thereby avoiding collision with the scraper kit 20. While ensuring the smooth execution of the cleaning task, the occupied flow cross-sectional area of ​​the exhaust pipe is reduced, thereby maximizing the guarantee of the normal exhaust flow rate of the exhaust pipe and avoiding affecting the normal exhaust work of the exhaust pipe.

[0041] like Figure 1 and Figure 4 As shown, the cleaning chamber 10 is divided into a plurality of regions at different positions by the reinforcing ribs 14, and a plurality of the scraping kits 20 respectively pass through the cleaning chamber 10 in corresponding advancing directions.

[0042] Specifically, in some embodiments, the ash cleaning chamber 10 can be divided into a plurality of ash cleaning small chambers at different positions by a plurality of reinforcing ribs 14. When the driver 3 drives the first driving rod 31 to drive the ash cleaning member 1 to clean the accumulated ash, the residual material can pass through the plurality of ash cleaning small chambers and fall and be discharged along the exhaust pipe wall, or be blown away by the wind pressure circulating in the exhaust pipe, thereby achieving the effect of cleaning the accumulated ash;

[0043] In order to smoothly pass through each cleaning cavity, the scraper kit 20 is also designed with a plurality of scraper kit small pieces for use with the corresponding cleaning cavities. The appearance of each scraper kit small piece is the same as the cavity contour of the cleaning cavity located in the corresponding forward direction, but a clearance fit design is adopted between each scraper kit small piece and the cleaning cavity in the corresponding forward direction, so that the scraper kit small piece can smoothly pass through the cleaning cavity in the corresponding forward direction, thereby satisfying the functional premise that the scraper kit 20 can freely penetrate the cleaning cavity 10 to clean the cleaning piece 1. The plurality of scraper kit small pieces are all installed on the end of the second driving rod 32 away from the driver 3 through the connecting platform 27. The driver 3 drives the second driving rod 32 through the connecting platform 27 to drive the plurality of scraper kit small pieces to pass through the cleaning cavity in the corresponding forward direction respectively, so as to achieve the effect of cleaning the accumulated dust of the cleaning piece 1.

[0044] like Figure 1 and Figure 4 As shown, the cleaning chamber 10 includes a first cleaning chamber 11, a second cleaning chamber 12 and a third cleaning chamber 13 separated by the reinforcing ribs 14, and the scraping kit 20 includes a first scraping kit 21 used in conjunction with the first cleaning chamber 11, a second scraping kit 22 used in conjunction with the second cleaning chamber 12 and a third scraping kit 23 used in conjunction with the third cleaning chamber 13.

[0045] Specifically, in some embodiments, the ash cleaning chamber 10 can be divided into a first ash cleaning chamber 11, a second ash cleaning chamber 12 and a third ash cleaning chamber 13 by a plurality of reinforcing ribs 14. When the driver 3 drives the first driving rod 31 to drive the ash cleaning member 1 to clean the accumulated ash, the residual material can pass through the first ash cleaning chamber 11, the second ash cleaning chamber 12 and the third ash cleaning chamber 13 and fall and be discharged along the exhaust pipe wall, or be blown away by the wind pressure circulating in the exhaust pipe, thereby achieving the effect of cleaning the accumulated ash;

[0046] In order to smoothly pass through the cleaning chamber 10, the scraper kit 20 is also designed with a first scraper kit 21 corresponding to the first cleaning chamber 11, a second scraper kit 22 corresponding to the second cleaning chamber 12, and a third scraper kit 23 corresponding to the third cleaning chamber 13. The shape of the first scraper kit 21 is the same as the cavity profile of the first cleaning chamber 11, but the first scraper kit 21 and the first cleaning chamber 11 are designed with a clearance fit, so that the first scraper kit 21 can smoothly pass through the first cleaning chamber 11. The second scraper kit 22 and the third scraper kit 23 are designed by analogy based on the design principle, so as to meet the functional premise that the scraper kit 20 can freely penetrate the cleaning chamber 10 to realize the cleaning of the cleaning part 1. The first scraper kit 21, the second scraper kit 22 and the third scraper kit 23 are all installed on the end of the second driving rod 32 away from the driver 3. The driver 3 drives the second driving rod 32 to drive the first scraper kit 21, the second scraper kit 22 and the third scraper kit 23 to pass through the first cleaning chamber 11, the second cleaning chamber 12 and the third cleaning chamber 13 respectively, so as to realize the effect of cleaning the accumulated dust of the cleaning part 1.

[0047] like Figure 1 , Figure 2 and Figure 4 As shown, a scraping blade structure 24 is provided on the side of the scraping kit 20 away from the driver 3 , and the scraping blade structure 24 is inclined from the side close to the cleaning chamber 10 toward the middle of the scraping kit 20 .

[0048] Specifically, in some embodiments, the scraping blade structure 24 is located on the side of the scraping kit 20 away from the driver 3 and at a position of the scraping kit 20 close to the cleaning chamber 10. The edge of the scraping blade structure 24 close to the cleaning chamber 10 is provided with a blade tip for cleaning accumulated dust. When a single scraping kit 20 is used, the scraping blade structure 24 is inclined from the side close to the cleaning chamber 10 toward the middle of the scraping kit 20 and is concave in an arc shape. When multiple scraping kits 20 are used in combination, the scraping blade structures 24 of multiple scraping kits 20 are inclined from the side close to the cleaning chamber 10 toward the middle of the cleaning member 1 and are concave in an arc shape. The arc-shaped surface is concave. Generally speaking, the scraping blade structure 24 is always designed to be inclined and concave from the side close to the cleaning chamber 10 toward the center of the diameter of the exhaust pipe, so that after the scraping blade structure 24 scrapes the accumulated dust on the cleaning part 1, the accumulated dust can fall into the middle of the exhaust pipe through the inclined arc-shaped surface and be discharged. The scraping blade structure 24 can concentrate the thrust on the tip of the blade at the edge of the structure, so that when the driver 3 pushes the scraping kit 20 through the driving rod 30, the scraping blade structure 24 can use the tip of the blade to concentrate the thrust to remove the accumulated residual materials, thereby improving the convenience of cleaning and improving the stability of cleaning.

[0049] like Figure 1 and Figure 3As shown, the scraper assembly 20 is inclined and has an ash discharge cavity 25 in the middle for facilitating ash discharge, and the support center of the ash cleaning component 1 is close to the lower inclined side.

[0050] Specifically, in some embodiments, the scraper kit 20 as a whole can be tilted at a certain angle relative to the radial plane of the exhaust pipe to form a lateral structure with one side higher and the other side lower. The higher side of the scraper kit 20 can form a conical structure that is convenient for concentrating thrust. The support center of the cleaning piece 1 is the connection fulcrum of the cleaning piece 1 for connecting the driving rod 30. The driving rod 30 connected to the cleaning piece 1 is closer to the lower side when the scraper kit 20 is tilted, so that the cleaning piece 1 forms an eccentrically supported structure. The design of the tilted scraper kit 20 can avoid the outer surface of the scraper kit 20 from being scratched when scraping residual materials accumulated on the cleaning piece 1. The side edges are subjected to force at the same time. When the accumulated residual material has a certain thickness, hardness and viscosity, it will produce a greater resistance to scraping. Therefore, the inclined scraper kit 20 can first contact the accumulated residual material from the higher side, concentrate the thrust on the higher side conical structure to scrape away the residual material one by one, and the remaining residual material is contacted and scraped away in turn by the elliptical edges generated by the inclination, so that the overall scraping process becomes smooth and smooth. This scraping method has less resistance, smaller elastic vibration generated during the scraping process, greater instantaneous impact force, and more effective in scraping away residual material with a certain resistance.

[0051] like Figure 1 , Figure 3 and Figure 4 As shown, the plurality of scraper sets 20 are arranged around the circumference of the first driving rod 31 at intervals, and the plurality of scraper sets 20 are all recessed toward the direction of the first driving rod 31 .

[0052] Specifically, in some embodiments, a plurality of scraper kits 20 are arranged at intervals around the circumference of the first driving rod 31, and the residual materials accumulated in the cleaning chamber 10 can be comprehensively cleaned from different positions. The center of the circumferential arrangement formed by the plurality of scraper kits 20 is provided with an escape opening for avoiding the outer diameter of the first driving rod 31, so that when the driver 3 pushes the plurality of scraper kits 20 through the second driver 32, the pushing force at each connection with the scraper kit 20 can be balanced, and a linear reciprocating motion can be made along the outer side of the first driving rod 31 through the escape opening. When the accumulated residual materials have a certain thickness, hardness and viscosity, a greater scraping resistance will be generated. Therefore, the use of a plurality of scraper kits 20 arranged at intervals can share the scraping resistance at different positions, avoiding the same scraper kit 20 from bearing all the scraping resistance, making the overall scraping process smooth and smooth. This scraping method has less resistance, and the elastic vibration generated during the scraping process is smaller, and the residual materials with a certain resistance can be more effectively scraped.

[0053] like Figures 1 to 3As shown, a cleaning connecting rod 15 for connection is provided between the cleaning member 1 and the first driving rod 31 , and a scraper sleeve bracket 26 for connection is provided between the scraper sleeve 20 and the second driving rod 32 . The scraper sleeve bracket 26 is arranged at intervals around the circumference of the cleaning connecting rod 15 .

[0054] Specifically, in some embodiments, the cleaning rod 15 is used to extend the maximum cleaning stroke of the cleaning member 1, and the scraper sleeve bracket 26 is used to extend the maximum cleaning stroke of the scraper sleeve 20. In the original design, for a longer exhaust pipe, the length of the drive rod 30 of the driver 3 needs to be extended to meet the maximum cleaning stroke, otherwise the entire straight exhaust pipe wall cannot be completely cleaned. After the cleaning rod 15 is added between the cleaning member 1 and the first drive rod 31, the cleaning stroke exceeding the maximum length of the drive rod 30 can be compensated by the cleaning rod 15. The cleaning stroke of the cleaning member 1 is extended by the cleaning rod 15 to achieve complete cleaning of the entire straight exhaust pipe wall. Similarly, the cleaning stroke of the scraper sleeve 20 is extended by the scraper sleeve bracket 26 to match the cleaning stroke of the cleaning member 1. The cleaning rod 15 and the scraper sleeve bracket 26 are used to extend the cleaning stroke, which effectively increases the cleaning range of the cleaning device and can be used in conjunction with exhaust pipes with longer lengths, thereby improving the practicality and adaptability of the cleaning device.

[0055] More specifically, the connection between the scraper sleeve bracket 26 and the second drive rod 32 is strengthened and the connection area is expanded by the connecting platform 27. The horizontal cross-sectional area of ​​the connecting platform 27 is larger than the horizontal cross-sectional area of ​​the second drive rod 32, so that multiple scraper sleeve brackets 26 can be conveniently installed on one side of the connecting platform 27, and the second drive rod 32 is connected to the other side of the connecting platform 27, thereby avoiding the difficulty of installing multiple scraper sleeve brackets 26 on the end of the second drive rod 32 away from the driver 3, thereby improving the stability of the connection structure.

[0056] like Figure 3 As shown, the exhaust pipe includes a pipe body 4 and the dust cleaning device installed on the pipe body 4.

[0057] Specifically, in some embodiments, the cleaning device can be fixed in position by installing the driver 3 on the outer side of the tube body 4 at one end of the cleaning piece 1 facing the driver 3, and then extending the cleaning piece 1 and the scraper kit 20 into the tube body 4's inner cavity 41, so that when the cleaning device is in operation, the cleaning piece 1 can make a scraping motion relative to the tube body's inner cavity 41 through the first driving rod 31 to clean residual materials on the wall of the tube body's inner cavity 41, and the scraper kit 20 can make an interlacing motion relative to the cleaning piece 1 through the second driving rod 32 to clean residual materials attached to the cleaning piece 1.

[0058] More specifically, the exhaust pipe can choose to use different types of drivers 3 such as motor transmission structure, cylinder transmission structure or hydraulic transmission structure as the main power source depending on the working environment, so as to adapt to different working environments or engineering projects with different cost budgets.

[0059] like Figures 1 to 4 As shown, the specific implementation of Example 1 of the utility model is as follows:

[0060] The driver 3 of this embodiment adopts a cylinder transmission structure, and realizes the extension and retraction of the driving rod 30 through the pneumatic principle.

[0061] Before use, the dust cleaning member 1 is installed on the protruding end of the first driving rod 31 through the dust cleaning connecting rod 15, and the scraper kit 20 is installed on the protruding end of the second driving rod 32 through the scraper kit bracket 26. After the scraper kit 20 is aligned with the dust cleaning chamber 10 and the gap of the scraper kit 20 passing through the dust cleaning chamber 10 is controlled, the dust cleaning member 1 is fixedly connected to the dust cleaning connecting rod 15, and the scraper kit 20 is fixedly connected to the scraper kit bracket 26. The end of the driver 3 facing the dust cleaning member 1 is installed on the outer side of the tube body 4 to fix the position of the dust cleaning device, and then the dust cleaning member 1 and the scraper kit 20 are extended into the inner tube cavity 41 of the tube body 4 to complete the installation of the dust cleaning device.

[0062] When in use, the cleaning device is powered on, and the driver 3 drives the first driving rod 31 to drive the cleaning member 1 to extend along the exhaust pipe wall in a direction away from the driver 3. After the cleaning member 1 reaches the maximum cleaning stroke, the driver 3 drives the first driving rod 31 to drive the cleaning member 1 to retract along the exhaust pipe wall in a direction close to the driver 3. The steps of extending and retracting are repeated. After multiple reciprocating scrapings, the residual substances accumulated on the exhaust pipe wall are cleaned.

[0063] In the process that the driver 3 drives the first driving rod 31 to drive the dust cleaning member 1 to clean the exhaust pipe wall, the driver 3 drives the second driving rod 32 alone to drive the scraper kit 20 to extend in the direction close to the dust cleaning member 1. When the scraper kit 20 passes through the dust cleaning chamber 10, the dust accumulated on the dust cleaning chamber 10 is cleaned by the dust scraping blade structure 24. After the scraper kit 20 passes through the dust cleaning chamber 10, the driver 3 immediately drives the second driving rod 32 to drive the scraper kit 20 to retract in the direction close to the driver 3. The scraper kit 20 passes through the dust cleaning chamber 10 again, and the dust accumulated on the dust cleaning chamber 10 is cleaned for the second time by the dust scraping blade structure 24. The steps of extending and retracting are repeated. After multiple reciprocating scrapings, the residual materials attached to the dust cleaning member 1 are cleaned.

[0064] After cleaning the exhaust pipe wall, the first driving rod 31 and the second driving rod 32 are reset to the starting point of the cleaning stroke. The dust cleaning device has completed one cycle of cleaning tasks and is waiting for the next cleaning.

[0065] like Figure 1 and Figure 4As shown, the specific implementation of Example 2 of the utility model is as follows:

[0066] Different from the first embodiment, the cleaning chamber 10 of the present embodiment is divided into a first cleaning chamber 11, a second cleaning chamber 12 and a third cleaning chamber 13 by a plurality of reinforcing ribs 14. When the driver 3 drives the first driving rod 31 to drive the cleaning member 1 to clean the accumulated dust, the residual material can pass through the first cleaning chamber 11, the second cleaning chamber 12 and the third cleaning chamber 13 and fall and be discharged along the exhaust pipe wall, or be blown away by the wind pressure circulating in the exhaust pipe, thereby achieving the effect of cleaning the accumulated dust;

[0067] In order to smoothly pass through the cleaning chamber 10, the scraper kit 20 is also correspondingly designed with a first scraper kit 21 for use with the first cleaning chamber 11, a second scraper kit 22 for use with the second cleaning chamber 12, and a third scraper kit 23 for use with the third cleaning chamber 13. The first scraper kit 21 and the first cleaning chamber 11 are designed with a clearance fit so that the first scraper kit 21 can smoothly pass through the first cleaning chamber 11. The second scraper kit 22 and the third scraper kit 23 can be designed by analogy based on the design principle of the first scraper kit 21, so as to meet the functional premise that the scraper kit 20 can freely penetrate the cleaning chamber 10 to clean the cleaning component 1. The first scraper kit 21, the second scraper kit 22 and the third scraper kit 23 are all installed at the end of the second driving rod 32 away from the driver 3. The driver 3 drives the second driving rod 32 to drive the first scraper kit 21, the second scraper kit 22 and the third scraper kit 23 to pass through the first cleaning chamber 11, the second cleaning chamber 12 and the third cleaning chamber 13 respectively, so as to achieve the effect of cleaning the accumulated dust of the cleaning component 1.

[0068] The specific implementation of Example 3 of the utility model is as follows:

[0069] Different from the first and second embodiments, the driver 3 of the present embodiment adopts a hydraulic transmission structure, and the extension and retraction of the driving rod 30 are realized by the principle of a hydraulic cylinder.

[0070] The specific implementation of Example 4 of the utility model is as follows:

[0071] Different from Examples 1, 2 and 3, the driver 3 of this embodiment adopts a motor transmission structure, which uses the rotational torque output by the motor to achieve the extension and retraction of the drive rod 30 through one or more of a variety of mechanical transmission methods such as gear transmission, sprocket transmission, thread transmission, worm gear transmission, etc.

[0072] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
