Description

Technical Field

[0001] This utility model relates to the field of furnace steam soot blowers, specifically a protective device for furnace steam soot blowers that can prevent steam leakage. Background Technology

[0002] Furnace steam soot blowers are typically installed on the furnace walls in boiler furnaces and other locations. They are devices that use the high-speed jet impact force of superheated steam to remove ash from heated surfaces. This ensures the safe and economical operation of the boiler and prevents accidents such as reduced heat transfer efficiency, increased flue gas temperature, and superheater tube rupture caused by ash accumulation. In order to extend the service life of furnace steam soot blowers, protective devices are often used for protection.

[0003] For example, Chinese utility model patent CN220582462U discloses a protective device for a steam sootblower, including a steam sootblower body, a main structure, and a collection mechanism. The main structure includes a base plate, a support frame, a main pipe, a nozzle, a gear ring, gears, a motor, a recovery pipe, a retaining ring, and an induced draft fan. In this protective device, steam discharged from the steam sootblower body reaches the inside of the main pipe. Through the nozzle slidably connected to the right side of the main pipe, the steam is ejected from the nozzle. Starting the motor drives the nozzle to rotate, causing it to spray steam. The retaining ring rotates and engages with the right side of the main pipe and the left side of the nozzle's outer wall. One end of the recovery pipe connects above the retaining ring and the upper middle part of the main pipe. Starting the induced draft fan causes steam leakage at the connection between the main pipe and the nozzle, guiding the steam from the inner wall of the retaining ring into the recovery pipe, thus returning the steam from the inner wall of the retaining ring to the main pipe for recovery and preventing steam leakage, thereby preventing steam leakage from affecting the use of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a protective device for a furnace steam soot blower that can prevent steam leakage, including a mounting plate 1, a steam soot blower body 2, a mounting hole 3, an adjusting rod 4, a bearing plate 5, a limiting plate 6, a steam pipe 7, an external connecting pipe 8, a vent hole 9, a connecting sleeve 10, a first sealing gasket 11, a second sealing gasket 12, absorbent cotton 13, a baffle strip 14, a guide hole 15, a movable plate 16, a third sealing gasket 17, a left fixing plate 18, a right fixing plate 19, a worm gear 20, and a worm 21. The steam soot blower body 2 is attached to the mounting plate 1, and the steam pipe 7 and the external connecting pipe 8 on the right side of the steam pipe 7 are fixedly connected to the steam soot blower body 2. The mounting plate 1 is provided with a fixing and anti-detachment device. The structure includes a fixed anti-detachment structure comprising a mounting hole 3, an adjusting rod 4, a bearing plate 5, and a limiting plate 6. The mounting hole 3 is symmetrically opened inside the outer end of the mounting plate 1. A sealing connection structure is provided between the steam pipe 7 and the outer pipe 8. The sealing connection structure includes a connecting sleeve 10, a first sealing gasket 11, and a second sealing gasket 12. The right end of the steam pipe 7 has evenly distributed vent holes 9. The steam pipe 7 has a detachable water filter structure inside. The detachable water filter structure includes absorbent cotton 13, a baffle 14, a guide hole 15, a movable plate 16, a third sealing gasket 17, a left fixing plate 18, a right fixing plate 19, a worm gear 20, and a worm 21. The absorbent cotton 13 is nested and fitted inside the steam pipe 7. Specific Implementation Example 1

[0030] To address the problems in existing technologies where it is inconvenient to secure the steam sootblower body 2 and prevent detachment, leading to steam leakage, this embodiment employs the following technical solution: Figure 1 , Figure 2 and Figure 3First, the steam soot blower body 2 can be placed against the upper surface of the middle part of the mounting plate 1. Then, the adjusting rod 4, which is engaged with the inner side of the middle part of the mounting plate 1, can be rotated. Since the outer sides of both ends of the adjusting rod 4 are threaded with the bearing plate 5, which is engaged with the mounting plate 1, and the bearing plate 5 is fixedly connected with the limiting plate 6, which is engaged with the mounting plate 1, and the limiting plate 6 is symmetrically arranged about the mounting plate 1, the rotation of the adjusting rod 4 makes it easy for the bearing plate 5 to drive the limiting plate 6 to move under the limit of the mounting plate 1 until the limiting plate 6 is engaged with the outer side of the steam soot blower body 2, so as to fix the steam soot blower body 2 and prevent it from falling off. Then, the device can be placed on the furnace wall at the waiting installation position. Finally, the screw can be inserted into the installation hole 3 opened inside the outer end of the mounting plate 1 to install and fix the device.

[0031] In the operation of the steam soot blower body 2, a steam pipe 7 is fixedly installed on the right side of the steam soot blower body 2. An external pipe 8 is provided on the right side of the steam pipe 7. The inner and outer ends of the steam pipe 7 and the external pipe 8 are connected by a connecting sleeve 10, so that steam can be ejected from the steam pipe 7 and then into the external pipe 8. The steam is then ejected from the evenly distributed vent holes 9 on the right end of the external pipe 8 to clean the furnace. A first sealing gasket 11 is pasted and fixed inside the connecting sleeve 10, which is in close contact with the steam pipe 7 and the external pipe 8. A second sealing gasket 12 is pasted and fixed on the left and right sides of the connecting sleeve 10, which is in close contact with the steam pipe 7 and the external pipe 8. Therefore, the sealing performance of the first sealing gasket 11 and the second sealing gasket 12 ensures the sealing of the connection between the steam pipe 7 and the external pipe 8 and prevents steam leakage. Specific Implementation Example 2

[0033] To address the problem of inconvenience in steam filtration and water cleaning in existing technologies, this embodiment employs the following technical solution: Figure 1 , Figure 2 , Figure 4 and Figure 5During the use of the steam soot blower body 2, a water-absorbing cotton 13 is nested and attached inside the steam pipe 7. Baffles 14, fixed to the steam pipe 7, are attached to both sides of the water-absorbing cotton 13.
