Description

Technical Field

[0001] This utility model relates to the field of boiler soot blowers, specifically a boiler soot blower with a support structure. Background Technology

[0002] Long telescopic sootblowers clean the dust in boilers by moving and rotating the sootblow tube into the boiler and venting gas. However, the sootblow tube is usually supported by rollers during rotation. This support cannot effectively support the section of the sootblow tube that extends into the boiler. At the same time, impurities on the outer end of the tube are not treated and are prone to friction during support. This causes impurities to come into contact with the support components, increasing wear and preventing effective contact and support between the impurities and the sootblow tube. This affects the stability of the support and the impurities adhering to the surface can easily cause corrosion and damage to the sootblow tube.

[0003] Therefore, this application designs a boiler soot blower with a support structure to solve this deficiency in the prior art. Utility Model Content

[0018] The toothed disc is mounted on one side inside the support cylinder with a fixing ring located outside the soot blowing tube. A cleaning brush that fits against the outside of the soot blowing tube is mounted on the inner wall of the fixing ring.

[0019] By adopting the above technical solution, the exterior of the sootblowing tube can be cleaned while providing support, thereby improving the support effect.

[0020] In a preferred embodiment of this invention, the support cylinder, the toothed disc, and the fixing ring are all concentric with the outer soot blowing tube.

[0035] In this embodiment, the rack 2 is fixedly installed on the top wall of the inner cavity of the box girder 1. A movable gearbox 3 that meshes with the rack 2 moves linearly along the trajectory on the box girder 1. A lifting valve 4 is fixedly installed on the outside of the box girder 1. An inner tube 5 that passes through the movable gearbox 3 is connected to the lifting valve 4.

A reduction motor 7 is fixedly installed on the outside of the movable gearbox 3. Gears 8 are fixedly installed on both the output shaft of the reduction motor 7 and the outside of the soot blowing outer tube 6. The transmission chain 9 meshes between the gears 8. The other end of the soot blowing outer tube 6 is provided with an air nozzle 10.

[0036] It should be noted that the air nozzle 10 has an air hole on its outside for discharging gas, and the movable gearbox 3 has a motor inside. The motor drives the gear disk to rotate and mesh with the rack 2, so as to drive the movement under the limiting movement of the movable gearbox 3.

[0037] Please see Figure 3 In this embodiment, the box girder 1 is provided with a telescopic support assembly for telescopically supporting the soot blowing outer pipe 6 that has been moved into the boiler.

[0038] It should be noted that the telescopic support assembly includes a movable support ring 12 that limits circumferential rotation outside the soot blowing outer pipe 6 and is located outside the box girder 1. A telescopic rod 11 connected to the movable support ring 12 is installed and fixed on the inner side of the box girder 1.

[0039] The telescopic rod 11 is composed of multiple movable cylinders that slide and connect with each other. The leftmost movable cylinder and the rightmost movable cylinder are respectively connected and fixed to the movable support ring 12 and the box girder 1. The outer side of the soot blowing pipe 6 is provided with an annular groove for the movable support ring 12 to rotate circumferentially.

[0040] The moving cylinders are not separated from each other.

[0041] Please see Figures 3 to 5 In this embodiment, the section of the soot blowing outer pipe 6 located outside the boiler is provided with a support and cleaning assembly for supporting and cleaning the soot blowing outer pipe 6.

[0042] It should be noted that the support cleaning component includes a support member and a cleaning member.

[0043] The support includes a support tube 21 installed and fixed to the outside of the rightmost movable tube, and a support tube 13 that is passed through and tightly fitted to the outer tube 6 of the soot blowing tube is installed and fixed to the other end of the support tube 21.

[0044] The cleaning component includes a toothed disc 14 that rotates circumferentially at the opening of the support cylinder 13 and is inseparable from the support cylinder 13 and is passed through by the soot blowing outer pipe 6, and a mounting base 17 that is fixed to the outside of the box girder 1. A micro motor 18 is fixedly mounted on the mounting base 17, and a transmission toothed disc 19 that meshes with the toothed disc 14 is fixedly mounted on the output shaft of the micro motor 18.

[0045] The toothed disc 14 is fixedly mounted on one side inside the support cylinder 13 with a fixing ring 15 located outside the soot blowing tube 6. A cleaning brush 16 that fits against the outside of the soot blowing tube 6 is fixedly mounted on the inner wall of the fixing ring 15.

[0046] The support cylinder 13, the toothed disc 14, and the fixing ring 15 are all concentric with the soot blowing outer tube 6.

[0047] The support cleaning component in this embodiment is provided with a collection component for collecting the cleaned impurities.

[0048] It should be noted that the collection assembly includes a suction tube 22 connected to the outside of the support tube 21, a vacuum cleaner 23 connected to the other end of the suction tube 22, and a perforation 20 opened on the outside of the support tube 13.

[0049] The suction port of the vacuum cleaner 23 is connected to the suction pipe 22.

[0050] The vacuum cleaner 23 is a prior art device, and the perforation 20 ensures airflow during dust suction and air extraction.

[0051] The working principle of the above embodiments is as follows:

[0052] During use, the gas is controlled to enter through the lifting valve 4, while the moving gearbox 3 is driven to move on the rack 2. The geared motor 7 drives the gear 8 to rotate. The transmission chain 9 is used to drive the moving gearbox 3 to move and drive the soot blowing pipe 6 to move and rotate at the same time, so that the gas is blown into the boiler through the nozzle 10 for soot cleaning.

[0053] As the soot blowing outer tube 6 moves and rotates into the boiler, the movable support ring 12 is in close contact with the soot blowing outer tube 6 and rotates to connect with it. At the same time, the telescopic rod 11 provides telescopic support for the movable support ring 12, ensuring that as the soot blowing outer tube 6 moves into the boiler, the telescopic rod 11 extends synchronously to work with the movable support ring 12 to effectively support the soot blowing outer tube 6 located in the boiler section.

[0054] In addition, the support tube 21 is connected to the telescopic rod 11 and is slidably sleeved on the soot blowing tube 6 located on the outer section of the boiler through the support tube 21, thus achieving effective support for the soot blowing tube 6 on the outer section of the boiler. At the same time, during the support process, the micro motor 18 works to drive the transmission gear plate 19 to rotate. By using the meshing of the transmission gear plate 19 and the gear plate 14, the gear plate 14 is driven to rotate on the support tube 13, which simultaneously drives the cleaning brush on the fixed ring 15 to rotate to clean the external impurities attached to the soot blowing tube 6. This avoids the impurities from being attached and increasing the wear of the support, and prevents the support from contacting the soot blowing tube 6, thus improving the support effect and preventing the impurities from causing corrosion of the soot blowing tube 6, thus forming an effective protection. After cleaning, the vacuum cleaner 23 is started. By utilizing the interconnection between the vacuum cleaner 23, the suction pipe 22, the support tube 21 and the support tube 13, the cleaned impurities are discharged and collected.

[0055] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
