Description

Technical Field

[0001] This invention relates to the field of boiler economizer technology, and in particular to a boiler economizer ash removal device. Background Technology

[0002] As a key heat exchange component of the boiler system, the cleanliness of the area surrounding the economizer's flue directly affects heat exchange efficiency and equipment operational stability. During long-term operation, dust and fly ash carried by the flue gas can gradually accumulate and deposit inside the flue. If not cleaned promptly, this can lead to decreased heat exchange efficiency and increased boiler energy consumption, or even cause flue blockage, affecting normal boiler output and potentially triggering equipment failure. Therefore, regular and effective cleaning of the economizer flue is a necessary measure to ensure the safe and efficient operation of the boiler system.

Detailed Implementation

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] An embodiment of the present invention includes a boiler economizer ash removal device, comprising: Insert 1 and adjusting plate 2, the insert 1 has multiple spaced movable gaps in the circumferential direction, and the adjusting plate 2 is rotatably provided on the movable gaps of the insert 1; Locking element 3 is provided on the insert 1 and is used to control the angle of the adjusting plate 2 within the movable gap. The adjusting plate 2 rotates to extend out of the movable gap or return to the movable gap. Collection component 4 is connected to the insert 1 to extract dust through the insert 1; The driving component 5 is disposed on the collecting component 4, and the driving component 5 drives the insert 1 to rotate; The collection component 4 includes a collection bin 41, and a ash discharge port 42 and an extraction port 43 provided on the collection bin 41.

[0027] The collection component 4 includes a collection chamber 41, and a dust discharge port 42 and an extraction port 43 provided on the collection chamber 41. The dust discharge port 42 can be connected to a dust discharge pipe to facilitate the operator to collect the dust particles that have been cleaned up. The dust discharge port 42 is connected to a negative pressure extraction device, such as a vacuum cleaner, so that the dust can be collected by negative pressure extraction to prevent the dust from escaping.

[0028] When using it, in the initial state, refer to Figure 1 In the state shown, all adjusting plates 2 are in the closed state. At this time, the gap between adjusting plate 2 and movable gap Q is the smallest. For the economizer pipe that needs to be cleaned, the device is tilted and its insertion angle is adjusted so that the ash discharge port 42 is located on the side closer to the ground. It should be noted that there are two symmetrically arranged handles 44 on the outer wall of the collection chamber 41. The handles 44 make it easy for the operator to hold the device. The insert 1 is rotated by the drive component 5. The operator inserts the insert 1 into the pipe to be cleaned. As the insert 1 rotates, it can crush and scrape the clumps of ash around the pipe, causing them to fall into the insert. Under the influence of gravity, the dust inside the insert 1 eventually falls into the collection chamber 41 and drops out of the ash discharge port 42. It is then discharged into a container for collection through the ash discharge pipe. Meanwhile, the extraction port 43 continuously extracts air through a negative pressure extraction device to collect the dust generated during the cleaning process. It should be noted that when the extraction port 43 extracts the dust, it not only extracts the dust inside the insert 1, but also extracts the dust raised around it through the gap between the movable gap Q and the adjusting plate 2. This effectively avoids dust generation, improves cleaning efficiency, and eliminates the need for secondary cleaning of the surrounding environment.

[0029] In addition, after initially cleaning the area around the economizer's pipes, the tilt angle of the adjusting plate 2 is adjusted using the locking component 3. When the adjusting plate 2 rotates, the maximum outer diameter of the insert 1 increases. At this point, when the insert 1 is rotated again using the driving component 5, the adjusting plate 2 can further scrape the pipe area and increase the cleaning radius. It is important to note that the overall rotation direction of the insert 1 should correspond to the orientation of the adjusting plate 2, as shown in the reference... Figure 8 As shown in the cross-sectional view, the insert 1 rotates counterclockwise as a whole. The adjusting plate 2 can guide the dust into the middle of the insert 1 and drop it into the collection part 4, which facilitates the collection and treatment of dust and ash that has been cleaned up.

[0030] In summary, by controlling the tilt angle of the adjustment plate 2, the cleaning range can be adjusted and stubborn dust around the pipe can be cleaned. The collection component 4 can guide and collect the dust and extract the dust generated during the operation of the equipment through the extraction port 43. This eliminates the traditional knocking method, reduces vibration, and avoids dust caused by vibration.

[0031] The economizer anti-clogging and ash removal device of the present invention can adjust the cleaning range by controlling the tilt angle of the adjusting plate 2 and clean the stubborn ash around the pipeline. The collecting component 4 can guide and collect the ash and extract the dust generated during the operation of the equipment through the extraction port 43. Compared with manual operation, it reduces the dust in the working environment and improves the cleaning efficiency.

[0032] In some embodiments, the insert 1 includes an upper ring 11 and a lower ring 13, with a plurality of circumferentially spaced connecting strips 12 connecting the upper ring 11 and the lower ring 13, and the space between two adjacent connecting strips 12 forming an movable gap. It should be noted that the upper ring 11 has an upper shaft hole 111, and the lower ring 13 has a lower shaft hole 131. The upper shaft holes 111 and the lower shaft holes 131 are arranged in a one-to-one correspondence and correspond to the number of adjusting plates 2.

[0033] The space between two adjacent connecting strips 12 constitutes the movable gap Q.

[0034] It should be noted that the connecting strip 12 is provided with an arc-shaped surface 121. The arc-shaped surface 121 can increase the fit between the plate 21 and the connecting strip 12, thereby reducing the gap between the plate 21 and the connecting strip 12.

[0035] In some embodiments, the insert 1 further includes a drilling portion 14, which is connected to the end of the lower ring body 13 away from the connecting strip 12. The radial dimension of the drilling portion 14 gradually decreases in the direction away from the lower ring body 13. The insert 1 also includes a drive shaft 15 and a spiral guide plate 16. The drive shaft 15 is provided on the drilling portion 14. The drive shaft 15 is connected to the output shaft of the drive member 5. The spiral guide plate 16 is spirally disposed on the drive shaft 15 along the axial direction of the drive shaft 15.

[0036] The drilling section 14 is composed of several arc-shaped inclined scrapers. The several arc-shaped inclined scrapers are arranged at equal intervals around the end of the lower ring body 13. The drilling section 14 can crush the clumps of dust facing its end when the insert 1 rotates, and facilitates the dust to enter the center of the insert 1.

[0037] The drilling part 14 is provided with a drive shaft 15, which is connected to the output shaft of the drive component 5. Through the transmission of the drive shaft 15, when the drive component 5 controls the drive shaft 15 to rotate, the entire insert 1 will be driven to rotate together.

[0038] The drive shaft 15 is equipped with a spiral guide plate 16, which facilitates the movement of accumulated ash into the collection bin 41. The radial dimension of the drilling part 14 gradually decreases in the direction away from the lower ring body 13, so that the drilling part can be inserted into the flue first, improving the convenience of cleaning.

[0039] In some embodiments, the adjusting plate 2 includes a plate body 21, a rotating shaft 211, and a lever 22, wherein the rotating shaft 211 is disposed on the plate body 21. The locking member 3 includes a fixing part 31 disposed at the end of the insert 1, and a rotating part 32 rotatably disposed on the fixing part 31, and also includes a push rod 33 disposed on the rotating part 32; The rotating part 32 rotates to push the lever 22 to rotate via the push rod 33, thereby adjusting the tilt angle of the plate 21.

[0040] Specifically, during use, the plate 21 is first adjusted to close the movable gap Q. At this time, the gap between the movable gap Q and the plate 21 is small, and most of the gas enters through the drilling part 14 when the extraction port 43 is evacuating. For the dust accumulated in the tubular economizer pipe, the drilling part 14 is first inserted into the dust accumulation area. The driving component 5 controls the rotation of the drilling part 14 and the spiral guide plate 16. The drilling part 14 crushes the dust accumulation area and guides it into the space formed by the plate 21 and the connecting strip 12. During this process, since the movable gap Q is closed, the drilling part 14 can maintain sufficient suction to suck up the dust. As the insert 1 is inserted into the dust accumulation area, the rotation of the driving shaft 15 will cause the spiral guide plate to... 16. Dust is pushed into the collection chamber 41. Under the action of gravity, the dust falls from the ash discharge port 42. The extraction port 43 extracts and collects the dust generated during the cleaning process. The advantage of this cleaning method is that the dust can be transported and discharged in time after it is cleaned up. When a large amount of dust is discharged, the gap between the economizer pipes increases. Then, the rotation of the rotating part 32 causes the push rod 33 to push the lever 22 to deflect. After the lever 22 deflects, the plate 21 deflects, and the gap between the movable gap Q and the plate 21 increases. When the extraction port 43 extracts, it can suck up the surrounding dust through this gap. Furthermore, due to the deflection of the plate 21, the cleaning radius of the equipment is increased, making it easier to scrape off the remaining clumps of dust around the perimeter.

[0041] Furthermore, the plate 21 is made of stainless steel or titanium alloy to improve structural strength.

[0042] In some embodiments, the adjusting plate 2 further includes a threaded sleeve 322 and a throttle 341. The rotating part 32 is provided with a threaded sleeve 322; the threaded sleeve 322 is internally threaded with a screw 34, one end of the screw 34 is provided with a handle 341, and the lever 22 is provided with a movable groove 221, the push rod 33 is slidably disposed in the movable groove 221. The handle 341 facilitates the rotation of the screw 34. By rotating the screw 34, the screw 34 can come into contact with the outside of the fixed part 31, thereby locking the rotating part 32 and the fixed part 31. When the rotating part 32 cannot rotate outside the fixed part 31, the angle of the plate 21 is fixed.

[0043] In some embodiments, the locking member 3 further includes a limiting strip 312, the fixing part 31 is provided with an annular groove 311, the limiting strip 312 is provided in the annular groove 311, the rotating part 32 is provided with a movable cavity 321, the limiting strip 312 is placed in the movable cavity 321, and the rotating part 32 is rotatably disposed in the annular groove 311.

[0044] It should be noted that there are two sets of limiting strips 312, which are symmetrically arranged in the annular groove 311, with multiple limiting strips 312 evenly distributed in each set. Adjacent limiting strips 312 form a positioning space W, which can be used for the screw 34 to engage. The rotating part 32 has a movable cavity 321; the limiting strips 312 are placed within the movable cavity 321. The limiting strips 312 enhance the limiting effect of the screw 34 when it abuts against the outer wall of the annular groove 311.

[0045] In some embodiments, the locking member 3 further includes a sealing plate 313, which is provided at the end of the fixing part 31, and the sealing plate 313 is rotatably connected to the end of the collection chamber 41. The sealing plate 313 seals the connection between the collection chamber 41 and the fixing part 31 to prevent dust from falling in.

[0046] In some embodiments, the locking member 3 further includes a push ring 331, a connecting block 332, a sliding plate 333, and a slip ring 314. The push rod 33 is connected to the push ring 331, the push ring 331 is provided with the connecting block 332, the connecting block 332 is provided on the rotating part 32, the connecting block 332 is provided with the sliding plate 333, and the fixing part 31 is provided with the slip ring 314.

[0047] A push ring 331 is connected to the push rod 33, and a connecting block 332 is provided on the push ring 331. The connecting block 332 is provided on the rotating part 32. A sliding piece 333 is provided on the connecting block 332. A sliding ring 314 is provided on the fixing part 31. The sliding ring 314 and the sliding piece 333 are slidably connected. The stability of the push ring 331 can be increased by the setting of the sliding ring 314 and the sliding piece 333.

[0048] The beneficial effects of the boiler economizer anti-clogging and ash removal mechanism of the present invention are as follows: The present invention can adjust the cleaning range by controlling the tilt angle of the adjusting plate 2 and clean the stubborn ash around the pipe. The collecting component 4 can guide and collect the ash and extract the dust generated during the operation of the equipment through the extraction port 43, eliminating the traditional knocking method, reducing vibration, and avoiding dust caused by vibration.
