However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0034] Example 1

[0035] Referring to Figures 1-10, this is the first embodiment of the present invention. This embodiment provides an adjustable pulverized coal distributor that can control the amount of pulverized coal entering the boiler through the connecting pipe 105, ensuring uniform pulverized coal distribution, reducing the possibility of localized coking, and improving safety. It includes a main component 100, comprising a support base 101, a distribution pipe 102 disposed on the upper side of the support base 101, a fixing base 103 disposed on the side wall of the distribution pipe 102, a fixing pipe 104 disposed on the outer surface of the distribution pipe 102, a connecting pipe 105 disposed on the upper side of the fixing pipe 104, and a maintenance seat 106 disposed on the fixing base 103. The segment component 200 includes a power component 201 disposed within the fixed base 103, a sliding component 202 disposed to the right of the power component 201, an adjusting component 203 disposed within the fixed base 103, a fixing component 204 disposed to the right of the sliding component 202, and a connecting component 205 disposed to the right of the adjusting component 203; the cleaning component 300 includes a rotating component 301 disposed to the left of the power component 201, a retracting component 302 disposed within the rotating component 301, a first cleaning component 303 disposed on the side wall of the retracting component 302, and a second cleaning component 304 disposed on the side wall of the retracting component 302.

[0036] Specifically, there are two support seats 101, which are symmetrically arranged. The two support seats 101 are fixedly connected to the distribution pipe 102. The distribution pipe 102 is fixedly connected to the fixed seat 103. There are multiple fixed pipes 104, which are equidistantly distributed. The fixed pipes 104 are fixedly connected to the connecting pipe 105. The fixed pipes 104 are connected to the distribution pipe 102. The connecting pipe 105 is connected to the fixed pipe 104. The maintenance seat 106 is fixedly connected to the fixed seat 103 by bolts. The maintenance seat 106 is used to maintain the motor 201b and electric push rod 201e inside the fixed seat 103. Multiple heat dissipation holes can be opened on the maintenance seat 106, and dust filters can be fixed in the heat dissipation holes to dissipate the heat generated by the motor 201b and electric push rod 201e. The left side of the distribution pipe 102 can be detachably installed at the coal powder separator outlet of the fan-type coal mill by means of flange or other means.

[0037] Furthermore, the power assembly 201 includes a connecting groove 201a disposed in the fixed base 103. A motor 201b is fixedly installed on the left wall of the connecting groove 201a. A first rotating shaft 201c and a second rotating shaft 201d are fixedly connected to the left and right sides of the motor 201b, respectively. An electric push rod 201e is fixedly connected to the left wall of the connecting groove 201a. The first rotating shaft 201c passes through the fixed base 103 and the distribution pipe 102 and is rotatably connected to the fixed base 103 and the distribution pipe 102.

[0038] Among them, the motor 201b model is a BLDC motor 201b with dual shaft output, and is operated with a suitable motor 201b controller so that the forward or reverse rotation of the output shaft of the motor 201b can be adjusted by the controller. This is existing technology and will not be described in detail here.

[0039] Preferably, the sliding assembly 202 includes a first groove 202a disposed on the right side of the second rotating shaft 201d, a first limiting groove 202b formed on the inner sidewall of the first groove 202a, a limiting block 202c slidably connected within the first limiting groove 202b, a sliding seat 202d fixedly connected to the inner sidewall of the limiting block 202c, a sliding plate 202e fixedly connected to the right side of the electric push rod 201e, an annular seat 202f fixedly connected to the sidewall of the sliding plate 202e, and an annular groove 202g formed on the outer surface of the sliding seat 202d; wherein the annular seat 202f and the annular groove 202g are slidably connected; the adjustment Component 203 includes a rotating seat 203a disposed in a connecting groove 201a, a fixing plate 203b fixedly connected to the outer surface of the rotating seat 203a, a leaf-shaped body 203c fixedly connected to the side wall of the fixing plate 203b, a connecting seat 203d fixedly connected to the outer surface of the distribution pipe 102, an adjusting groove 203e disposed in the connecting seat 203d, an adjusting through groove 203f opened on the outer surface of the distribution pipe 102, a first gear 203g fixedly connected to the right side of the rotating seat 203a, and a second gear 203h fixedly connected to the right side of the sliding seat 202d; wherein, the adjusting groove 203e communicates with the adjusting through groove 203f.

[0040] It should be noted that multiple first limiting grooves 202b and limiting blocks 202c are provided, and the multiple first limiting grooves 202b and multiple limiting blocks 202c are arranged in a ring array. The limiting blocks 202c are slidably connected to the first limiting grooves 202b. The sliding seat 202d is slidably connected to the first groove 202a. The ring seat 202f and the ring groove 202g can play a role in not hindering the rotation of the sliding seat 202d. Two rotating seats 203a are provided, and the two rotating seats 203a are symmetrically arranged. Multiple fixing plates 203b and multiple connecting seats 203d are provided, and the multiple fixing plates 203b and multiple connecting seats 203d are equidistantly distributed. Plate 203b is fixedly connected to the blade body 203c by bolts to facilitate the replacement of the blade body 203c. The two longitudinal blade bodies 203c and the two longitudinal fixing plates 203b can be combined to form a circular plate, as shown in Figure 5. When the rotating seat 203a rotates and drives the fixing plate 203b to rotate counterclockwise, the blade body 203c rotates into the adjusting groove 203e along the adjusting groove 203e and the adjusting through groove 203f, as shown in Figure 6, so as to control the amount of pulverized coal entering the boiler through the connecting pipe 105. The second gear 203h is meshed with the two first gears 203g, and the second gear 203h is located between the two first gears 203g.

[0041] In use, the device is first installed at the outlet of the pulverized coal separator of the fan-type coal mill, and the connecting pipe 105 is connected to the boiler. Pulverized coal then enters the distribution pipe 102, and is then transported from the fixed pipe 104 to the connecting pipe 105, and then from the connecting pipe 105 to the boiler. Next, the electric push rod 201e is activated, causing the sliding plate 202e to move the annular seat 202f to the right. Under the action of the annular groove 202g, the sliding seat 202d is subjected to a rightward pulling force, causing the sliding seat 202d to move in the direction of the first groove 202a, the first limiting groove 202b, and the limiting block 202c. The second gear 203h is driven to move to the right. When the limiting block 202c contacts the right wall of the first limiting groove 202b, the second gear 203h meshes with the first gear 203g. At this time, the motor 201b runs, and the second rotating shaft 201d drives the sliding seat 202d to rotate clockwise, causing the second gear 203h to rotate clockwise. Since the second gear 203h meshes with the two first gears 203g and is located between the two first gears 203g, the two first gears 203g rotate in opposite directions, thereby driving the rotating seat 203a and the fixed plate 203. Rotation b causes the leaf blade body 203c to slide into the connecting seat 203d through the adjusting groove 203f and adjusting groove 203e, causing the two longitudinally corresponding leaf blade bodies 203c to move away from each other, as shown in Figure 6. Alternatively, the second rotating shaft 201d drives the sliding seat 202d and the second gear 203h to rotate counterclockwise, causing the first gear 203g to rotate clockwise, causing the two longitudinally corresponding leaf blade bodies 203c to move closer together, thus adjusting the angle of the leaf blade body 203c. By adjusting the angle of the leaf blade body 203c, it is easier to control the flow of water into the fixed pipe through the distribution pipe 102. The amount of pulverized coal in pipes 104 and 105 is adjusted to effectively regulate the supply of pulverized coal, thereby avoiding excessive or insufficient pulverized coal in the boiler. This ensures uniform distribution of pulverized coal within the boiler, reduces the possibility of localized coking, and improves safety. By increasing or decreasing the amount of pulverized coal, the position and intensity of pulverized coal combustion in the boiler furnace can be adjusted, thereby changing the shape and height of the flame and influencing the distribution and regulation of steam temperature. Furthermore, changing the amount of pulverized coal can also adjust the distribution of heat load, avoiding slagging problems caused by excessive localized heat load, and further reducing the possibility of localized coking.

[0042] In summary, through the cooperation of the power component 201, the sliding component 202, and the regulating component 203, the amount of pulverized coal entering the connecting pipe 105 can be controlled, thereby effectively controlling the amount of pulverized coal entering the boiler, making the pulverized coal entering the boiler uniform, reducing the possibility of local coking, improving safety, and ensuring the safe operation of the boiler.

[0043] Example 2

[0044] Referring to Figures 4 to 10, this is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an adjustable leaf-shaped coal powder distributor, which includes the fixing component 204, which includes a fixing column 204a disposed on the right side of the sliding plate 202e. An L-shaped seat 204b is fixedly connected to both the front and rear sides of the outer surface of the fixing column 204a. A limiting insert 204c is fixedly connected to the left side of the L-shaped seat 204b. A limiting slot 204d is opened on the right side of the first gear 203g. The limiting insert 204c is inserted into the limiting slot 204d.

[0045] Specifically, the fixed post 204a is fixedly connected to the sliding plate 202e, and multiple limiting slots 204d are provided, which are equidistantly distributed. When the second gear 203h moves to the right and gradually meshes with the first gear 203g, the limiting post 204c gradually disengages from the limiting slot 204d. This ensures that when the second gear 203h is fully meshed with the first gear 203g, the limiting post 204c completely disengages from the limiting slot 204d. This allows the second gear 203h to drive the first gear 203g to rotate when the second rotating shaft 201d drives the sliding seat 202d to rotate. When the second gear 203h and the first gear 203g are not meshed, the limiting post 204c is fully inserted into the limiting slot 204d, thus limiting the first gear 203g.

[0046] Furthermore, the connecting assembly 205 includes a rotating column 205a disposed on the right side of the first gear 203g, a first through groove 205b opened on the right side of the fixed seat 103, a connecting plate 205c fixedly connected to the outer surface of the rotating column 205a, a slider 205d fixedly connected to the left side of the connecting plate 205c, a sliding groove 205e opened on the right side of the fixed seat 103, a scale 205f fixedly connected to the right side of the fixed seat 103, and a connecting block 205g fixedly connected to the side wall of the connecting plate 205c; wherein, the slider 205d is slidably connected to the sliding groove 205e, and the first through groove 205b communicates with the connecting groove 201a.

[0047] Specifically, the rotating column 205a is fixedly connected to the first gear 203g, the rotating column 205a is movably connected to the first through groove 205b, the slide groove 205e is arc-shaped, and under the action of the slide groove 205e, the second gear 203h can only drive the first gear 203g to rotate 90° forward and backward. The connecting block 205g can indicate the scale line on the scale 205f, so as to make it easy to know how much angle the leaf body 203c has been adjusted.

[0048] In use, in conjunction with Embodiment 1, when the sliding seat 202d drives the second gear 203h to move gradually to the right, the sliding plate 202e will drive the fixed post 204a and the L-shaped seat 204b to move gradually to the right, causing the limiting post 204c to gradually disengage from the limiting slot 204d. When the second gear 203h is fully engaged with the first gear 203g, the limiting post 204c completely disengages from the limiting slot 204d to avoid affecting the rotation of the first gear 203g driven by the second gear 203h. When the second gear 203h drives the first gear 203g to rotate, the rotating post 205a rotates along with the first gear 203g under the action of the first through slot 205b. This causes the connecting plate 205c to drive the slider 205d to slide within the groove 205e. Under the constraint of the groove 205e, the connecting plate 205c can only drive the slider 205d to slide 90° within the groove 205e. When the slider 205d slides 90° within the groove 205e, the first gear 203g drives the rotary seat 203a, the fixed plate 203b, and the leaf blade body 203c to rotate to 90°. At this time, the two longitudinally corresponding leaf blade bodies 203c are moved away from each other to the maximum extent, and the leaf blade bodies 203c are completely located within the connecting seat 203d, maximizing the amount of coal powder entering the fixed pipe 104 through the distribution pipe 102. When the slider 205d is in its initial position... As shown in Figures 2 and 3, at this time, the two longitudinally corresponding leaf-shaped bodies 203c approach each other, minimizing the amount of coal powder entering the fixed pipe 104 through the distribution pipe 102. When the rotating column 205a drives the connecting plate 205c to rotate, the connecting block 205g moves with the connecting plate 205c. With the cooperation of the connecting block 205g and the scale 205f, it is convenient to check the angle of adjustment of the leaf-shaped body 203c. After the angle of the leaf-shaped body 203c is adjusted, the electric push rod 201e is activated, causing the sliding plate 202e to move to the left, so that the sliding seat 202d moves towards the first groove 202 under the action of the annular seat 202f and the annular groove 202g. The sliding plate 202e causes the second gear 203h to gradually move away from the first gear 203g. At the same time, the sliding plate 202e drives the fixed post 204a and the L-shaped seat 204b to move to the left, causing the limiting post 204c to gradually slide into the limiting slot 204d. When the second gear 203h completely disengages from the first gear 203g, the limiting post 204c is fully inserted into the limiting slot 204d, achieving the function of quickly limiting and fixing the first gear 203g, preventing the first gear 203g from rotating under its own weight, and making the leaf body 203c stably fixed at the required angle position, thus improving the angle adjustment effect of the leaf body 203c.

[0049] In summary, in conjunction with Embodiment 1, and through the connecting component 205, the angle of adjustment of the leaf-shaped body 203c is limited, and it is easy to know how much angle the leaf-shaped body 203c has been adjusted. Through the fixing component 204, the first gear 203g can be limited and fixed, thereby improving the angle adjustment effect of the leaf-shaped body 203c.

[0050] Example 3

[0051] Referring to Figures 6 to 11, this is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an adjustable blade coal powder distributor, which includes a rotating assembly 301 comprising a rotating seat 301a disposed on the left side of the first rotating shaft 201c. A fixing block 301b is fixedly connected to the outer surface of the rotating seat 301a, and a connecting column 301c is fixedly connected to the side wall of the fixing block 301b.

[0052] Specifically, multiple rotating components 301 are provided, and the multiple rotating components 301 are distributed at equal intervals. The corresponding rotating components 301 are located between two adjacent leaf bodies 203c. The rotating seat 301a on the right side is fixedly connected to the left side of the first rotating shaft 201c by bolts, and two adjacent rotating seats 301a are fixedly connected by bolts.

[0053] Furthermore, the shrinking assembly 302 includes a second groove 302a disposed on the side wall of the connecting post 301c. A second limiting groove 302b is formed on the inner side wall of the second groove 302a. A limiting plate 302c is slidably connected within the second limiting groove 302b. A shrinking post 302d is fixedly connected to the side wall of the limiting plate 302c. A first spring 302e is fixedly connected to the side wall of the limiting plate 302c. A shrinking plate 302f is fixedly connected to the side wall of the shrinking post 302d. The first spring 302e is fixedly connected to the inner side wall of the second groove 302a. The first cleaning assembly 303 includes a first cleaning plate 303a disposed on the side wall of the shrinking plate 302f. A first inclined surface 303b is provided on the side wall of the first cleaning plate 303a. A second cleaning plate 302f is fixedly connected to the side wall of the shrinking plate 302f. 3c, the second cleaning plate 303c has a second inclined surface 303d on its side wall, a support 303e is fixedly connected to the inner side wall of the distribution pipe 102, the support 303e has a second through groove 303f on its side wall, the support 303e has a third inclined surface 303g on its side wall, and the support 303e has a fourth inclined surface 303h on its side wall; wherein, the first cleaning plate 303a and the second cleaning plate 303c are symmetrically arranged; the second cleaning assembly 304 includes a support plate 304a disposed on the side wall of the first cleaning plate 303a, a support plate 304b is fixedly connected to the side wall of the support plate 304a, a scraper 304c is fixedly connected to the side wall of the support plate 304b, and a third through groove 304d is opened on the outer surface of the rotating seat 301a; wherein, the scraper 304c is slidably connected to the third through groove 304d.

[0054] Specifically, the shrinkage column 302d is slidably connected to the second groove 302a, the shrinkage plate 302f is I-shaped, the first inclined surface 303b is adapted to the third inclined surface 303g, the second inclined surface 303d is adapted to the fourth inclined surface 303h, multiple supports 303e are provided, and the multiple supports 303e are equidistantly distributed, the rotating seat 203a is rotatably connected to the second through groove 303f, and the supports 303e serve to support the rotating seat 203a, and the scraper 304c contacts the surface of the leaf body 203c, serving as a... The function of scraping off the coal powder adhering to the surface of the leaf body 203c is that the support plate 304b and scraper 304c are slidably connected to the third through groove 304d. This allows the support plate 304b and scraper 304c to slide into the third through groove 304d when the first cleaning plate 303a or the second cleaning plate 303c moves toward the rotating seat 301a under the action of the first inclined surface 303b and the third inclined surface 303g or the second inclined surface 303d and the fourth inclined surface 303h, thus preventing the rotating seat 301a from obstructing the movement of the scraper 304c.

[0055] In use, in conjunction with Embodiment 1, after the motor 201b runs, it drives the first rotating shaft 201c to rotate, which in turn drives the rotating seat 301a to rotate. This causes the fixed block 301b to drive the connecting column 301c to rotate with the rotating seat 301a. This allows the first cleaning plate 303a and the second cleaning plate 303c to scrape off the coal powder adhering to the inner wall of the distribution pipe 102, and the scraper 304c to scrape off the coal powder adhering to the blade body 203c. This prevents the coal powder from adhering to the inner wall of the distribution pipe 102 and the surface of the blade body 203c for a long time, thus avoiding the impact of subsequent cleaning. To avoid wasting pulverized coal, when the first cleaning plate 303a contacts the support 303e, the first cleaning plate 303a will drive the shrink plate 302f and shrink column 302d to move into the connecting column 301c under the action of the limiting plate 302c, the second limiting groove 302b, the second groove 302a, the first inclined surface 303b, and the third inclined surface 303g. When the first cleaning plate 303a moves to the fourth inclined surface 303h with the rotation of the rotating seat 301a, the first cleaning plate 303a moves away from the connecting column 301c under the action of the first spring 302e. The first cleaning plate 303a vibrates under the action of the first spring 302e, causing it to shake off the coal dust adhering to the first cleaning plate 303a or the second cleaning plate 303c, further preventing the waste of coal dust. Similarly, when the second cleaning plate 303c contacts the support 303e, the second cleaning plate 303c will drive the shrink plate 302f and shrink column 302d to move towards the connection under the action of the limiting plate 302c, the second limiting groove 302b, the second groove 302a, the second inclined surface 303d and the four inclined surfaces. When the second cleaning plate 303c moves within the column 301c and rotates with the rotating seat 301a to the third inclined surface 303g, under the action of the first spring 302e, the second cleaning plate 303c will move away from the connecting column 301c. This allows the second cleaning plate 303c to shake off the coal dust adhering to the surface under the action of the first spring 302e, improving the cleaning effect. At the same time, the rotation of the cleaning component 300 can buffer the impact of coal dust on the leaf body 203c to a certain extent, extending the service life of the leaf body 203c.

[0056] In summary, through the cooperation of the rotating component 301, the shrinking component 302, the first cleaning component 303, and the second cleaning component 304, the coal powder adhering to the inner wall of the distribution pipe 102 and the surface of the blade body 203c can be scraped off, avoiding affecting subsequent cleaning and achieving the effect of avoiding coal powder waste.
