Description

Technical Field

[0001] The present application relates to the technical field of boiler cleaning, and in particular to a swinging sootblower. Background Art

[0002] Sootblowers are primarily used to clean the heating surfaces of boiler tube bundles. However, in existing sootblowers, the telescopic movement and rotation of the sootblowing lance are driven by the same motor and reduction gearbox. This means the lance can only rotate in one direction, either clockwise or counterclockwise. This can easily damage catalyst layers installed on the top of some boilers. To address this issue, a swinging sootblower driven by a connecting rod mechanism is currently available. However, due to its limited and inflexible swing angle, it can only be compensated by using two or more nozzles arranged at different angles. However, this can also lead to poor sootblowing results and low efficiency due to factors such as nozzle diameter and medium flow pressure, thus presenting drawbacks. Summary of the Invention

[0031] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0032] like Figures 1-10 As shown, a swing sootblower according to an embodiment of the present application includes:

[0033] The support frame 100 has a running gear box 200 disposed on the inner side of the top of the support frame 100;

[0034] The reducer frame 300 is fixedly connected to the reducer 400. The upper end of the reducer frame 300 is fixedly connected to the running gear box 200, and the lower end of the reducer frame 300 is slidably connected to both sides of the lower end of the support frame 100;

[0035] The transmission member 500 has its upper end fixedly connected to the output shaft of the reducer 400 and its lower end fixedly connected to the purge pipe 600;

[0036] The purge pipe 600 is slidably connected to both sides of the lower end of the support frame 100, and one end of the purge pipe 600 is fixedly connected to the reduction frame 300. When in use, the running gear box 200 drives the reduction frame 300 to slide in the support frame 100, thereby driving the reducer 400 to move and driving the purge pipe 600 to move. When the purge pipe 600 moves to the purge area, the reducer 400 is started to drive the transmission member 500 to drive, thereby driving the purge pipe 600 to swing, so as to sweep the ash on both sides and the bottom of the boiler. In this device, the running gear box 200 and the reducer 400 respectively control the extension and contraction of the purge pipe 600 and the swing of the purge pipe 600. Therefore, the swing amplitude of the purge pipe 600 can be controlled by controlling the rotation amplitude and rotation direction of the output shaft of the reducer 400 and transmitting through the transmission member 500, without interfering with the extension and contraction of the purge pipe 600, thereby solving the problems of inflexible swing angle, poor soot blowing effect and low efficiency in the prior art.

[0037] like Figure 2 As shown, the reduction gear frame 300 includes an upper bracket 310 and a lower bracket 320, the running gear box 200 is fixedly connected to the upper bracket 310, the purge pipe 600 is fixedly connected to the lower bracket 320, and the reduction gear 400 is fixedly connected between the upper bracket 310 and the lower bracket 320, wherein the two sides of the lower bracket 320 are slidably connected to the two sides of the inner edge of the support frame 100.

[0038] like Figure 3 As shown, the running gear box 200 includes a mounting cavity 210, a rack 220, and a drive gear box body 230. The mounting cavity 210 is fixedly connected to both sides of the support frame 100. The rack 220 is disposed in the mounting cavity 210. The output gear of the drive gear box body 230 is engaged with the rack 220. When the drive gear box body 230 is started, the output gear of the drive gear box body 230 rotates, causing the drive gear box body 230 to move back and forth on the rack 220, thereby driving the purge pipe 600 to extend and retract back and forth.

[0039] like Figure 4 As shown, travel pressure blocks 240 are installed on both sides of the drive gearbox body 230, and sensing pressure blocks 250 are installed at both ends of the rack 220. During movement, when the travel pressure block 240 on one side touches the sensing pressure block 250 on the same side, the drive gearbox body 230 automatically loses power and stops moving. The provision of the travel pressure blocks 240 and sensing pressure blocks 250 prevents the drive gearbox body 230 from overloading and causing damage to the device.

[0040] like Figure 5As shown, the drive gear box body 230 includes a box body 231, a drive motor 232, an active bevel gear 233, a driven bevel gear 234, a connecting shaft 235 and a running gear 236. The drive motor 232 is fixedly connected to the box body 231, the active bevel gear 233 is fixedly connected to the output end of the drive motor 232, the driven bevel gear 234 is meshed with both sides of the active bevel gear 233, and the driven bevel gear 234 is meshed perpendicularly with the active bevel gear 233. One end of the connecting shaft 235 is fixedly connected to the driven bevel gear 234, and the other end of the connecting shaft 235 passes through the side wall of the box body 231. The running gear 236 is fixedly connected to the other end of the connecting shaft 235, and the running gear 236 is meshed on the rack 220. Starting the drive motor 232 drives the active bevel gear 233 to rotate, drives the driven bevel gear 234 to rotate, thereby drives the connecting shaft 235 to rotate, and causes the running gear 236 to move on the rack 220.

[0041] like Figure 6 As shown, the transmission member 500 includes a driving gear 510, a driven gear 520, and a sprocket 530. The driving gear 510 is fixedly connected to the output end of the reducer 400, and the driven gear 520 is fixedly connected to the outer periphery of the purge pipe 600. The driving gear 510 and the driven gear 520 are respectively engaged with the two ends of the sprocket 530. The output shaft of the reducer 400 rotates back and forth, driving the driving gear 510 to swing back and forth, and the driven gear 520 to swing back and forth through the sprocket 530, thereby driving the purge pipe 600 to swing back and forth, achieving the purge pipe 600 swinging back and forth. By adjusting the speed of the reducer 400 and the gear ratio of the driving gear 510 and the driven gear 520, the swing frequency of the purge pipe 600 can be adjusted to achieve a better blowing effect with a smaller sootblowing medium flow rate.

[0042] like Figure 7 As shown, the purge pipe 600 includes a purge pipe body 610, a connecting air duct 620, and a supporting slide 630. A blowing nozzle is provided at the end of the purge pipe body 610. The connecting air duct 620 is fixedly connected to the other end of the purge pipe body 610. The supporting slide 630 is snapped onto the purge pipe body 610. The supporting slide 630 is slidably connected to both sides of the support frame 100. An air valve 640 is provided at one end of the connecting air duct 620. The connecting air duct 620 is connected to the duct machine for conveying soot blowing medium. The soot blowing medium passes through the connecting air duct 620 and the purge pipe body 610 and reaches the blowing nozzle before being ejected. When the purge pipe body 610 is extended or retracted, it drives the supporting slide 630 to slide on the support frame 100, and the supporting slide 630 provides support for the purge pipe body 610.

[0043] like Figure 8As shown, a striker valve 540 is fixedly connected to the side of the driven gear 520, and a stroke detector 550 is correspondingly provided on the reducer frame 300. When the purge pipe 600 rotates, the striker valve 540 touches the stroke detector 550, transmitting a touch signal to the reducer 400, causing the output shaft of the reducer 400 to automatically change its rotation direction. When another striker valve 540 touches the stroke detector 550 again, it transmits a touch signal to the reducer 400, causing the reducer 400 to change its output shaft's rotation direction again, thereby causing the purge pipe 600 to automatically swing.

[0044] like Figure 8 and Figure 9 As shown, the support slide 630 includes a slide 631, a slide frame 632, and a clamping ring 633. The slide 631 is fixedly connected to both sides of the support frame 100, the slide frame 632 is slidably connected to the slide 631, and the slide frame 632 is fixedly connected to the support groove 634. The purge pipe body 610 is placed on the support groove 634. The clamping ring 633 is fixedly connected to the outer side of the purge pipe body 610, and the clamping ring 633 respectively abuts on both sides of the support groove 634. Rollers 635 are evenly arranged in the clamping ring 633. When the purge pipe body 610 is extended or retracted, the slide frame 632 slides in the slide 631, and the support groove 634 supports the purge pipe body 610. When the purge pipe body 610 swings, the rollers 635 rotate accordingly.

[0045] like Figure 10 As shown, telescopic struts 110 are fixedly connected to both sides of the bottom of the support frame 100. The bottom of the telescopic struts 110 is fixedly connected to the bottom of the base plate 120. Universal pulleys 130 are provided at the four corners of the bottom of the base plate 120. The telescopic struts 110 can be used to adjust the height of the purge pipe 600, so that the purge pipe 600 can adapt to different boiler heights and can be easily moved by the universal pulleys 130.

[0046] In summary, the working principle of a swing-type soot blower according to an embodiment of the present invention is as follows: starting the driving motor 232 drives the active bevel gear 233 to rotate, drives the driven bevel gear 234 to rotate, thereby drives the connecting shaft 235 to rotate, so that the running gear 236 moves on the rack 220, drives the reduction frame 300 to slide in the support frame 100, thereby drives the reducer 400 to move, drives the gear box body 230 to move, drives the sweep pipe body 610 to move, makes the sliding frame 632 slide on the slide groove 631, and at the same time the support groove 634 provides support force for the sweep pipe body 610. When the sweep pipe body 610 moves to the sweeping area, the output shaft of the reducer 400 rotates back and forth, drives the active gear 510 It swings back and forth, and the driven gear 520 is made to swing back and forth through the sprocket 530, thereby driving the sweep pipe 600 to swing back and forth, realizing the swinging and blowing of the sweep pipe 600 back and forth, thereby sweeping the ash on both sides and the bottom of the boiler. The running gear box 200 and the reducer 400 respectively control the extension and contraction of the sweep pipe 600 and the swinging of the sweep pipe 600. By adjusting the speed of the reducer 400 and the gear ratio of the driving gear 510 and the driven gear 520, the swinging frequency of the sweep pipe 600 is adjusted to achieve a better blowing effect with a smaller soot blowing medium flow rate, and does not interfere with the telescopic movement of the sweep pipe 600, thereby solving the problems of inflexible swinging angle, poor soot blowing effect and low efficiency in the prior art.
