Description

Technical Field

[0001] The present application relates to the technical field of boiler soot removal, and in particular to an angle-adjustable boiler soot blower. Background Art

[0002] During the operation of the boiler, dust is easily accumulated on the heating surface, which affects the thermal efficiency and service life of the boiler. The boiler soot blower is a device used to blow away the dust accumulated on the heating surface of the boiler.

[0003] At present, there are many kinds of boiler soot blowers on the market, which remove the accumulated ash on the heating surface by spraying high-speed airflow. However, the existing boiler soot blowers usually have a fixed spray angle and cannot adjust the spray direction according to the actual situation of the heating surface, resulting in incomplete cleaning effect. Utility Model Content

[0004] The utility model aims to solve or at least alleviate the problem that the existing boiler soot blower usually has a fixed spray angle and cannot adjust the spray direction according to the actual situation of the heating surface, resulting in incomplete soot cleaning effect.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An angle-adjustable boiler sootblower comprises a frame with a U-shaped structure, a sootblower body is fixedly connected to the inner wall of one end of the frame, a sootblower body is rotatably connected to the sootblower body, the sootblowing structure comprises an exhaust pipe fixedly connected to the exhaust end of the sootblower body, the end of the exhaust pipe away from the sootblower body is sealed, a rotating seat rotatably connected to the exhaust pipe is sleeved on the middle section of the exhaust pipe, a sootblowing pipe for sootblowing is fixedly connected to the outer side wall of the rotating seat, a through hole connected to the inner cavity of the rotating seat is also provided on the side wall of the middle section of the exhaust pipe, a guide assembly for guiding the end of the sootblowing pipe away from the rotating seat is installed on the end of the frame away from the sootblower body, and an adjustment assembly for adjusting the angle of the sootblowing pipe is installed on the inner wall of the middle section of the frame.

[0007] By adopting the above technical scheme, an exhaust pipe is installed on the exhaust end of the soot blower body arranged in the inner cavity at one end of the frame, and a rotating seat rotatably connected to the exhaust pipe is sleeved on the exhaust pipe, and the side wall of the exhaust pipe is connected with the inner cavity of the rotating seat through a through hole, and the soot blowing pipe is fixedly connected to the rotating seat. When the user needs to adjust the soot blowing angle of the soot blowing pipe, the motor can be started to drive the gear to rotate. Since the gear is meshed with the lower surface of the toothed plate, the arc-shaped toothed plate can be driven to move left and right above the gear, thereby driving the soot blowing pipe to rotate around the center of the rotating seat to adjust the soot blowing angle of the soot blowing pipe. After the adjustment is completed, the electromagnetic column is energized and the electromagnetic column is tightly adsorbed on the guide plate by magnetic force to lock the position of the soot blowing pipe, thereby avoiding the problem that the existing boiler soot blower usually has a fixed injection angle and cannot adjust the injection direction according to the actual situation of the heating surface, resulting in incomplete cleaning effect.

[0008] Optionally, annular sealing grooves are provided on the exhaust pipes on both sides of the through hole, a sealing ring is bonded to the inner wall of the rotating seat, the sealing ring is embedded in the inner cavity of the sealing groove and is rotatably connected to the exhaust pipe through the sealing groove.

[0009] By adopting the above technical solution, a sealing groove and a sealing ring are provided to seal the connection between the rotating seat and the exhaust pipe, which greatly improves the sealing performance of the connection between the rotating seat and the exhaust pipe without affecting the free rotation of the rotating seat.

[0010] Optionally, the guide assembly includes two guide plates with an arc-shaped structure fixedly connected at two ends of the frame, and the guide plates are provided with guide grooves with an arc-shaped structure, and the guide grooves are concentric with the center of the rotating seat.

[0011] By adopting the above technical scheme, an arc-shaped structure guide groove concentric with the center of the rotating seat is provided to guide the free end of the sootblowing pipe. At the same time, the sootblowing pipe is clamped by using the guide plates on both sides to avoid the sootblowing pipe from vibrating due to high-speed air flow in the sootblowing pipe, which may easily cause the connection between the sootblowing pipe and the rotating seat to break and fall off after a long time.

[0012] Optionally, electromagnetic columns are fixedly connected to the outer walls on both upper and lower sides of the sootblowing pipe, and one end of the electromagnetic column away from the sootblowing pipe passes through the guide plate through the guide groove and is slidably connected to the guide plate.

[0013] By adopting the above technical solution, the guide plate is made of iron, cobalt or nickel that can be adsorbed by magnetic materials. After the soot blowing angle of the soot blowing tube is adjusted, the electromagnetic column can be energized and the magnetic force can be used to tightly adsorb the electromagnetic column on the guide plate to lock the position of the soot blowing tube.

[0014] Optionally, the adjustment component includes a connecting sleeve which is sleeved on the middle section of the sootblowing pipe and fixedly connected to the sootblowing pipe, and a gear plate with an arc-shaped structure which is concentric with the center of the rotating seat is fixedly connected to the lower surface of the connecting sleeve.

[0015] By adopting the above technical solution, a connecting sleeve is provided to increase the contact surface between the toothed plate and the outer surface of the sootblowing pipe, thereby greatly improving the stability of the connection between the toothed plate and the sootblowing pipe.

[0016] Optionally, the adjustment component also includes a motor installed on the inner wall of the frame below the gear plate, and a gear is fixedly connected to the output end of the motor, and the gear is meshed and transmission-connected with the lower surface of the gear plate.

[0017] By adopting the above technical solution, when the soot blowing angle of the soot blowing pipe needs to be adjusted, the motor can be started to drive the gear to rotate. Since the gear is meshed with the lower surface of the toothed plate, the arc-shaped toothed plate can be driven to move left and right above the gear, thereby driving the soot blowing pipe to rotate around the center of the rotating seat to adjust the soot blowing angle of the soot blowing pipe.

[0018] Optionally, a mounting seat is welded on the motor, and bolts are passed through the mounting seat. The bolts penetrate the mounting seat and are screwed to the frame.

[0019] By adopting the above technical solution, a mounting seat is provided to improve the stability of the motor installation, and a screw connection method is adopted, which not only ensures a stable connection, but also facilitates the installation and removal of the motor.

[0020] In summary, the beneficial effects of this application are as follows:

[0021] The present application achieves coordinated arrangements among structures such as an exhaust pipe, a rotating seat, a through hole, and a sootblowing pipe, wherein an exhaust pipe is installed on the exhaust end of a sootblower body arranged in an inner cavity at one end of a frame, and a rotating seat rotatably connected to the exhaust pipe is sleeved on the exhaust pipe, and a side wall of the exhaust pipe is communicated with the inner cavity of the rotating seat through a through hole, and the sootblowing pipe is fixedly connected to the rotating seat.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] See also Figure 1-3 An angle-adjustable boiler sootblower comprises a frame 1 with a U-shaped structure, wherein the frame 1 is provided to support the overall structure, and a sootblower body 2 is fixedly connected to the inner wall of one end of the frame 1. High-speed air is blown out through the sootblower body 2 to act on the heating surface of the boiler to clean the dust on the heating surface of the boiler.

[0028] A sootblower structure is rotatably connected to the sootblower body 2, and the sootblowing structure includes an exhaust pipe 3 fixedly connected to the exhaust end of the sootblower body 2. The end of the exhaust pipe 3 away from the sootblower body 2 is sealed, which can effectively prevent air from being discharged from the end of the exhaust pipe 3.

[0029] A rotating seat 5 rotatably connected to the exhaust pipe 3 is sleeved on the middle section of the exhaust pipe 3, and a soot blowing pipe 8 for soot blowing is fixedly connected to the outer wall of the rotating seat 5, so that the soot blowing pipe 8 can rotate freely on the exhaust pipe 3 through the rotating seat 5 to adjust the soot blowing angle of the soot blowing pipe 8.

[0030] A through hole 7 connected to the inner cavity of the rotating seat 5 is also provided on the side wall of the middle section of the exhaust pipe 3. Since the air cannot be discharged through the end of the exhaust pipe 3, it can only enter the inner cavity of the rotating seat 5 through the through hole 7 and finally enter the soot blowing pipe 8. The high-speed flowing air is discharged through the soot blowing pipe 8 to clean the dust on the heating surface of the boiler.

[0031] A guide assembly for guiding the end of the sootblowing pipe 8 away from the rotating seat 5 is installed on the end of the frame 1 away from the sootblower body 2. The guide assembly is provided to guide the rotational movement path of the sootblowing pipe 8 away from the end of the sootblower body 2.

[0032] An adjusting component for adjusting the angle of the sootblowing pipe 8 is installed on the inner wall of the middle section of the frame 1 .

[0033] Reference Figure 1, the exhaust pipe 3 is provided with an annular sealing groove 4 on both sides of the through hole 7, and a sealing ring 6 is bonded to the inner wall of the rotating seat 5, and the sealing ring 6 is embedded in the inner cavity of the sealing groove 4 and is rotatably connected with the exhaust pipe 3 through the sealing groove 4. The sealing groove 4 and the sealing ring 6 are provided to seal the connection between the rotating seat 5 and the exhaust pipe 3, which greatly improves the sealing performance of the connection between the rotating seat 5 and the exhaust pipe 3 without affecting the free rotation of the rotating seat 5.

[0034] Reference Figure 1 and Figure 3 The guide assembly includes two guide plates 9 with an arc structure fixedly connected at both ends of the frame 1. The guide plates 9 are provided with guide grooves 10 with an arc structure, and the guide grooves 10 are concentric with the center of the rotating seat 5. The guide grooves 10 with an arc structure concentric with the center of the rotating seat 5 are provided to guide the free end of the sootblowing tube 8. At the same time, the guide plates 9 on both sides are used to clamp the sootblowing tube 8, so as to avoid the sootblowing tube 8 vibrating due to the high-speed flow of air in the sootblowing tube 8, which may easily cause the sootblowing tube 8 to break and fall off at the connection between the sootblowing tube 8 and the rotating seat 5 after a long time.

[0035] Reference Figure 1 Electromagnetic columns 11 are fixedly connected to the outer walls of both upper and lower sides of the sootblowing tube 8. The end of the electromagnetic column 11 away from the sootblowing tube 8 passes through the guide plate 9 through the guide groove 10 and is slidably connected to the guide plate 9. The guide plate 9 is made of iron, cobalt or nickel material that can be adsorbed by magnetic materials. After the sootblowing angle of the sootblowing tube 8 is adjusted, the electromagnetic column 11 can be energized, and the electromagnetic column 11 is tightly adsorbed on the guide plate 9 by magnetic force to lock the position of the sootblowing tube 8.

[0036] Reference Figure 3 The adjustment assembly includes a connecting sleeve 12 which is sleeved on the middle section of the sootblowing pipe 8 and fixedly connected to the sootblowing pipe 8, and a toothed plate 13 with an arc structure which is concentric with the center of the rotating seat 5 is fixedly connected to the lower surface of the connecting sleeve 12. The connecting sleeve 12 is provided to increase the contact surface between the toothed plate 13 and the outer surface of the sootblowing pipe 8, which greatly improves the stability of the connection between the toothed plate 13 and the sootblowing pipe 8.

[0037] Reference Figure 1 The adjustment assembly further includes a motor 14 mounted on the inner wall of the frame 1 below the toothed plate 13, and a gear 15 is fixedly connected to the output end of the motor 14, and the gear 15 is meshed and connected to the lower surface of the toothed plate 13. When the soot blowing angle of the soot blowing pipe 8 needs to be adjusted, the motor 14 can be started to drive the gear 15 to rotate. Since the gear 15 is meshed and connected to the lower surface of the toothed plate 13, the arc-shaped toothed plate 13 can be driven to move left and right above the gear 15, thereby driving the soot blowing pipe 8 to rotate around the center of the rotating seat 5 to adjust the soot blowing angle of the soot blowing pipe 8.

[0038] Reference Figure 3The motor 14 is welded with a mounting seat, and a bolt is passed through the mounting seat, and the bolt is screwed to the frame 1 after passing through the mounting seat. The mounting seat is provided to improve the stability of the installation of the motor 14, and the screw connection mode is adopted, which is not only stable, but also convenient for installing and removing the motor 14.

[0039] When the user needs to adjust the soot blowing angle of the soot blowing pipe 8, the motor 14 can be started to drive the gear 15 to rotate. Since the gear 15 is meshed with the lower surface of the toothed plate 13, the toothed plate 13 of the arc structure can be driven to move left and right above the gear 15, thereby driving the soot blowing pipe 8 to rotate around the center of the rotating seat 5 to adjust the soot blowing angle of the soot blowing pipe 8. After the adjustment is completed, the electromagnetic column 11 is energized, and the electromagnetic column 11 is tightly adsorbed on the guide plate 9 by magnetic force to lock the position of the soot blowing pipe 8, thereby avoiding the problem that the existing boiler soot blower usually has a fixed injection angle and cannot adjust the injection direction according to the actual situation of the heating surface, resulting in incomplete soot cleaning effect.
