Description

Technical Field

[0001] This invention relates to the field of cleaning technology for the inner walls of square channels, and in particular to a cleaning device for cleaning the inner walls of square channels. Background Technology

[0002] During long-term boiler operation, dust and particulate matter carried by flue gas will continuously deposit on the catalyst surface. Over time, this can easily cause blockage of the pores and micropores of the catalyst module. Blockage can lead to increased system pressure, decreased ammonia utilization, and abnormal catalyst temperature, which not only affects the normal operating efficiency of the boiler but may also increase energy consumption and maintenance costs.

[0003] Currently, traditional cleaning methods have significant limitations in addressing the need to clean impurities adhering to the inner surface of the pores in square catalyst modules. Common manual cleaning or simple mechanical sweeping methods are difficult to adapt to the geometric characteristics of square channels and cannot achieve comprehensive and thorough cleaning of all parts of the inner wall. In particular, blind spots are easily formed in the corners and complex structures of the channels, resulting in low cleaning efficiency and unstable results. Therefore, developing a special device that can accurately and efficiently clean impurities on the inner wall of square channels has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning device for cleaning the inner wall of a square hole, thereby enabling the cleaning of the inner wall with a square hole.

[0005] To achieve the above objectives, the present invention provides a cleaning device for cleaning the inner wall of a square channel, comprising a grid-type operating platform for fixing a catalyst module, an integrated bracket above the grid-type operating platform, and multiple slidable cleaning components suspended side by side on the integrated bracket. Each cleaning component includes a Reuleaux triangular mechanism and a brush, the brush being installed at the lower part of the output end of the Reuleaux triangular mechanism, and a vision sensor being fixedly installed at the bottom of the output end of the Reuleaux triangular mechanism. A position adjustment mechanism for adjusting the height and horizontal position of the integrated bracket is provided on one side of the grid-type operating platform, and a dust collection component is provided at the bottom of the grid-type operating platform. The position adjustment mechanism, the dust collection component, the Reuleaux triangular mechanism, and the vision sensor are all electrically connected to a controller.

[0006] Furthermore, the integrated bracket is provided with a guide groove, and multiple connecting blocks are slidably installed in the guide groove along the length direction. The bottom end of each connecting block is fixedly installed with the cleaning component. A first rack is fixedly installed at the top end inside the guide groove. A first gear that meshes with the first rack is rotatably installed on the connecting block. A first motor for driving the first gear to rotate is fixedly installed on the connecting block.

[0007] Furthermore, the position adjustment mechanism includes a back plate and a first slide rail, the first slide rail being slidably mounted vertically on the back plate via a screw and nut mechanism.

[0008] Furthermore, the integrated bracket is slidably mounted on the first slide rail, a second rack is fixedly mounted on the first slide rail, a second gear that meshes with the second rack is rotatably mounted on the integrated bracket, and a second motor for driving the second gear to rotate is fixedly mounted on the integrated bracket.

[0009] Furthermore, the integrated bracket is mounted on the sliding nut of the lead screw nut mechanism via a linear guide rail, and the linear guide rail is electrically connected to the controller.

[0010] Furthermore, the Reuleaux triangular mechanism includes a drive chamber, a drive motor, and a Reuleaux triangular block. The drive chamber is fixedly installed at the bottom end of the connecting block. The cross-section of the inner wall of the drive chamber is square. The drive motor is fixedly installed at the top end inside the drive chamber. The Reuleaux triangular block is connected to the output shaft of the drive motor via a universal joint. The brush is installed at the bottom end of the Reuleaux triangular block.

[0011] Furthermore, the brush has a split structure, including multiple self-locking tension rods arranged in a circumferential array at equal intervals. A brush sleeve with bristles is fitted on the outer side of the cylindrical contour formed by the multiple self-locking tension rods. The bottom end of the Reuleaux triangular block has a cone structure. Guide grooves are equally spaced along the circumference of the cone structure. The self-locking tension rods are slidably installed in the guide grooves. An adjustment knob is rotatably installed on the outside of the cone structure on the Reuleaux triangular block. The outside of the self-locking tension rods and the adjustment knob are connected by a threaded engagement.

[0012] Furthermore, the visual sensor is fixedly installed at the bottom end of the vertebral structure.

[0013] Furthermore, the dust collection assembly includes a dust collection hopper and a negative pressure fan. The dust collection hopper is fixedly installed at the bottom end of the grid-type operating platform, and the negative pressure fan is installed on the output pipe at the bottom end of the dust collection hopper.

[0014] Furthermore, multiple ball bearings are provided between the self-locking tensioning rod and the guide groove.

[0015] In this invention, multiple cleaning components are slidably mounted on an integrated bracket. Combined with a position adjustment mechanism, the height and horizontal position of the integrated bracket are precisely controlled, enabling precise positioning of the brush before cleaning.

The dust collection component at the bottom of the grid-type operating platform can simultaneously remove the cleaned impurities, avoiding secondary pollution. During the cleaning process, the controller coordinates the control of each component, realizing fully automated operation from brush positioning, impurity removal, and impurity recovery. Compared with traditional manual or simple mechanical cleaning methods, this significantly improves the cleaning efficiency and thoroughness of the inner wall of the square channel.

[0027] Example 1

[0028] like Figures 1-6As shown, this invention provides a cleaning device for cleaning the inner wall of a square channel, including a grid-type operating platform 1 for fixing a catalyst module. The grid-type operating platform 1 has through holes to facilitate dust falling downwards. To prevent the catalyst module from moving, baffles or fixing holes can be provided on the grid-type operating platform 1. An integrated support 6 is provided above the grid-type operating platform 1. A position adjustment mechanism for adjusting the height and horizontal position of the integrated support 6 is provided on one side of the grid-type operating platform 1. The position adjustment mechanism includes a back plate 5 and a first slide rail 19. The first slide rail 19 is vertically slidably mounted on the back plate 5 via a screw and nut mechanism 18. The screw and nut mechanism 18 is an existing type. The technical details will not be elaborated here. The lead screw and nut mechanism 18 can drive the first slide rail 19 to move in the Z-axis direction, thereby realizing the lifting and lowering of the integrated bracket 6. The integrated bracket 6 is slidably mounted on the first slide rail 19. The two can slide relative to each other but cannot rotate relative to each other. The specific implementation structure in this embodiment is as follows: a second rack 20 is fixedly mounted on the first slide rail 19, a second gear 21 that meshes with the second rack 20 is rotatably mounted on the integrated bracket 6, and a second motor 22 for driving the second gear 21 to rotate is fixedly mounted on the integrated bracket 6. By controlling the second motor 22 to drive the second gear 21 to rotate, the integrated bracket 6 can move in the Y-axis direction.

[0029] Multiple cleaning components that can slide along the X-axis are suspended in parallel on the integrated bracket 6. The corresponding installation structure is as follows: a guide groove is opened on the integrated bracket 6, and multiple connecting blocks 23 are slidably installed in the guide groove along the length direction. A cleaning component is fixedly installed at the bottom of each connecting block 23. A first rack 11 is fixedly installed at the top of the guide groove. A first gear 12 that meshes with the first rack 11 is rotatably installed on the connecting block 23. A first motor 13 for driving the first gear 12 to rotate is fixedly installed on the connecting block 23. The first motor 13 drives the first gear 12 to rotate, thereby moving the cleaning component to adapt to different hole positions.

[0030] The cleaning components include a Reuleaux triangular mechanism and a brush 10. The brush 10 is installed at the lower part of the output end of the Reuleaux triangular mechanism. Specifically, the Reuleaux triangular mechanism includes a drive chamber 7, a drive motor 8, and a Reuleaux triangular block 9. The drive chamber 7 is fixedly installed at the bottom of the connecting block 23. The cross-section of the inner wall of the drive chamber 7 is square. The drive motor 8 is fixedly installed at the top inside the drive chamber 7. The Reuleaux triangular block 9 is connected to the output shaft of the drive motor 8 via a universal joint. The brush 10 is installed at the lower end of the Reuleaux triangular block 9. In this embodiment, the brush 10 is a split structure, including three self-locking tensioning rods 15 arranged in an equally spaced circular array. A set of brushes 10 with bristles is fitted around the outer side of the cylindrical outline formed by the three self-locking tensioning rods 15. The bottom of the Reuleaux triangular block 9 is provided with a cone structure 14. Three guide grooves are equally spaced along the circumference of the cone structure 14. The self-locking tension rod 15 is slidably installed in the guide groove. In order to ensure smooth sliding, multiple ball bearings 16 are provided between the self-locking tension rod 15 and the guide groove. An adjustment knob 17 is rotatably installed on the outside of the cone structure 14 on the Reuleaux triangular block 9. The adjustment knob 17 has a certain damping when rotated. The outside of the self-locking tension rod 15 is connected to the adjustment knob 17 by a threaded engagement. By rotating the adjustment knob 17, the three self-locking tension rods 15 with a "claw" structure can be brought together inward or expanded outward to achieve fine adjustment of the distance between the bristles and the inner wall of the channel. It is suitable for square holes of different sizes to be cleaned.

[0031] A vision sensor is fixedly installed at the bottom of the cone structure 14 to identify the location of the hole. The vision sensor feeds back an electrical signal to the controller 4, which then controls the position of the cleaning component and controls its operation.

[0032] The bottom of the grid-type operating table 1 is equipped with a dust collection component, which includes a dust collection hopper 2 and a negative pressure fan 3. The dust collection hopper 2 is fixedly installed at the bottom of the grid-type operating table 1, and the negative pressure fan 3 is installed on the output pipe at the bottom of the dust collection hopper 2. The negative pressure fan 3 is used to extract the dust that falls into the dust collection hopper 2 during cleaning.

[0033] In this solution, the position adjustment mechanism, dust collection component, Reuleaux triangular mechanism and vision sensor are all electrically connected to the controller 4. The control panel of the controller 4 is aligned with the table surface of the grille-type operating table 1 for easy manual button operation.

[0034] Working principle: Place the catalyst module to be cleaned on the grid-type operating platform 1, turn on the negative pressure fan 3 to create negative pressure, and promptly suck away the dust that falls on the catalyst holes. Move the integrated bracket 6 to one side of the catalyst module above the holes through the position adjustment mechanism. Start the controller 4. The vision sensors in each cleaning component sense the relative position of the center of the catalyst module holes. The controller 4 controls the first motor 13 to work and adjusts the position of the connecting block 23 so that the brush 10 is accurately aligned with each hole of the catalyst module. After alignment, the controller 4 controls the drive motor 8 to work and controls the brush 10 to rotate along the inner wall of the catalyst module holes in a square shape, sweeping away the dust and other particles attached to the inner wall of the catalyst module holes. These particles are then sucked away by the negative pressure fan 3, achieving the purpose of cleaning the catalyst module.

[0035] Example 2

[0036] The difference between this embodiment and embodiment 1 is that the integrated bracket 6 is mounted on the sliding nut of the lead screw nut mechanism 18 via a linear guide rail. The linear guide rail is electrically connected to the controller 4, and the controller 4 controls the movement of the slider on the linear guide rail, thereby realizing the movement of the integrated bracket 6 in the Y-axis direction.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
