Description

Technical Field

[0001] The present invention relates to the technical field of chimneys, and specifically to an environmentally friendly and clean steel chimney structure. Background Art

[0002] Industrial chimneys mainly include reinforced concrete chimneys and steel chimneys. Steel chimneys are favored because of their short construction period and relatively low cost. A steel chimney includes a chimney body. After being used for a period of time, a layer of dirt is likely to adhere to the inner wall of the chimney body.

[0003] In this regard, in the Chinese patent with the application number N201910326477.1, "An Energy-Saving and Environment-Friendly Self-Cleaning Chimney" is disclosed. As Figure 13 shown, at the upper end of the chimney body 1, a rain shield 8 is fixedly connected through a plurality of connecting rods 7. The lower end of the rain shield 8 is rotatably connected to a rotating shaft 9. A runner 10 is coaxially and fixedly connected to the rotating shaft 9. A plurality of inclined diversion grooves are formed in the side wall of the runner 10. When the diversion grooves are blown by wind, the runner 10 will rotate around the rotating shaft 9. A scraping strip 11 arranged in a spiral shape is fixedly connected to the lower end of the rotating shaft 9. When the runner 10 rotates, the scraping strip 11 will be driven to clean the inner wall of the chimney body 1.

[0004] Although the design provided by the above patent can clean the inner wall of the chimney body, when the chimney is put into use, the above patent design cannot protect the upper part of the inner wall of the chimney body. For example, during the use of the chimney, when the flue gas is discharged to the upper part of the chimney body, since the temperature of the flue gas decreases, the flue gas condenses into liquid, which aggravates the corrosion of the upper part of the inner wall of the chimney body.

[0005] Therefore, how to enable a steel chimney to not only clean the inner wall of the chimney body but also alleviate the corrosion of the upper part of the inner wall of the chimney body by the condensed flue gas is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0006] Aiming at the above-mentioned deficiencies existing in the prior art, the present invention provides an environmentally friendly and clean steel chimney structure, which can not only clean the inner wall of the chimney body but also alleviate the corrosion of the upper part of the inner wall of the chimney body by the condensed flue gas.

[0007] To achieve the above object, the invention provides the following technical solutions:

[0008] An environment-friendly and clean steel chimney structure, comprising a chimney body, a wind-driven rotating mechanism, a lifting mechanism, a base, a lining, and a distance-adjusting mechanism. A wind-driven rotating mechanism for driving the base to rotate and a lifting mechanism for driving the base to lift are provided at the upper end of the chimney body. The lining includes at least two arc-shaped plates that can be assembled into a ring. A distance-adjusting mechanism for adjusting the distance between the end of the arc-shaped plate and the base is provided on the base. When one end of the arc-shaped plate is close to the base and the other end of the arc-shaped plate is far from the base, the end of the arc-shaped plate far from the base can scrape the inner wall of the chimney body.

[0009] Further, the wind-driven rotating mechanism includes a support frame, a rotation driving member, and a support shaft. The upper end of the chimney body is rotatably connected to the support frame. The rotation driving member includes a plurality of arc-shaped wind blades surrounding the upper end of the chimney body. All the arc-shaped wind blades are connected to the support frame. The support frame is connected to the upper end of the support shaft. The base rotates coaxially with the support shaft and is vertically slidably connected to the support shaft.

[0010] Further, a long hole is provided on the side wall of the support shaft. The length of the long hole is arranged along the axial direction of the support shaft. The base is provided with a shaft hole for vertically slidingly cooperating with the support shaft, and a connection key for vertically slidingly cooperating with the long hole is provided on the hole wall of the shaft hole.

[0011] Further, the lifting mechanism includes a retracting and releasing driving member and a towing rope. The retracting and releasing driving member is provided on the support frame. A receiving cavity for communicating with the long hole is provided inside the support shaft. One end of the towing rope is connected to the retracting and releasing driving member, and the other end of the towing rope is connected to the base after passing through the receiving cavity and the long hole in sequence.

[0012] Further, the distance-adjusting mechanism includes a first adjusting cylinder, a first adjusting rod, and a first fixing member. The first adjusting cylinder is sleeved on the upper part of the base and is connected to the base through the first fixing member. One end of the first adjusting rod is rotatably connected to the first adjusting cylinder, and the other end of the first adjusting rod is rotatably connected to one end of the arc-shaped plate.

[0013] Further, the distance-adjusting mechanism further includes a fixing rod. One end of the fixing rod is connected to the base, and the other end of the fixing rod is rotatably connected to the end of the arc-shaped plate far from the first adjusting rod.

[0014] Further, the distance-adjusting mechanism further includes a second adjusting cylinder, a second adjusting rod, and a second fixing member. The second adjusting cylinder is sleeved on the lower part of the base and is connected to the base through the second fixing member. One end of the second adjusting rod is rotatably connected to the second adjusting cylinder, and the other end of the second adjusting rod is rotatably connected to the end of the arc-shaped plate far from the first adjusting rod.

[0015] Furthermore, the arc-shaped plate includes a first frame, a second frame, and single plates. The first frame and the second frame are arranged side by side. A plurality of single plates arranged in parallel are provided between the first frame and the second frame. The upper end of the single plate is detachably connected to the first frame, and the lower end of the single plate is detachably connected to the second frame. The first frame is rotatably connected to the first adjusting rod, and the second frame is rotatably connected to the second adjusting rod.

[0016] Furthermore, scraping blades for abutting against the side wall of the support shaft are provided at both the upper and lower ends of the base.

[0017] Compared with the prior art, the beneficial effects of the invention are as follows:

[0018] 1. In the steel chimney of the present invention, since all the arc-shaped plates can not only be assembled into a circular inner lining to protect the upper part of the inner wall of the chimney body, but also use the arc-shaped plates to scrape the dirt on the inner wall of the chimney, so as to clean the inner wall of the chimney body. Therefore, the steel chimney of the present invention can not only clean the inner wall of the chimney body, but also relieve the corrosion of the condensed flue gas on the upper part of the inner wall of the chimney body.

[0019] 2. Unexpectedly, the inner lining realizes the dual use of the structure. First, it is used to protect the upper part of the inner wall of the chimney body, and second, it is used to scrape the inner wall of the chimney body. Therefore, there is no need to separately set a scraping strip to scrape the inner wall of the chimney body, or there is no need to separately set an inner lining to protect the upper part of the inner wall of the chimney body, which helps to save resources and protect the environment.

[0020] 3. Even more unexpectedly, when the wind-driven rotating mechanism drives the base and the arc-shaped plates on the base to rotate together, the arc-shaped plates can Figure 6 also act as exhaust fan blades in the shown state, and help the dirt cleaned during the cleaning process to be discharged from the chimney body.

[0021] 4. In the steel chimney of the present invention, the wind-driven rotating mechanism uses wind power to drive the base and the arc-shaped plates on the base to rotate. Therefore, using wind power, a green energy source, helps to further improve the environmental protection effect.

[0022] 5. In the steel chimney of the present invention, the distance adjusting mechanism for adjusting the distance between the end of the arc-shaped plate and the base can realize the adjustment of all the arc-shaped plates at one time, which is beneficial to improving the adjustment efficiency, and thus beneficial to improving the cleaning efficiency of the steel chimney.

[0023] 6. In the steel chimney of the present invention, after one end of the arc-shaped plate rotatably connected to the first adjusting rod is worn, it can continue to use the end of the arc-shaped plate rotatably connected to the second adjusting rod to scrape the inner wall of the chimney body according to Figures 9 to 10 the state change, which is beneficial to extending the service life of the arc-shaped plate, saving the number of times of replacing the arc-shaped plate, and is beneficial to further saving costs and protecting the environment.

[0024] 7. Unexpectedly, in the steel chimney of the present invention, a distance adjusting mechanism can be used to adjust the distances between the two ends of the arc-shaped plate and the base, so that all the arc-shaped plates can be accommodated inside the chimney body with different inner diameters, and by adjusting the distances between the two ends of the arc-shaped plate and the base, the arc-shaped plate can be made to scrape the inner wall of the chimney body with different inner diameters, improving the flexibility of use.

[0025] 8. In the steel chimney of the present invention, when a single plate is damaged, the single plate can be replaced separately without replacing the entire arc-shaped plate, which is conducive to further improving the service life of the arc-shaped plate, further saving the resources and costs for replacement and repair, and is conducive to further environmental protection.

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] Embodiment 1:

[0049] As Figures 1 - 5 shown, an environmentally friendly and clean steel chimney structure includes a chimney body 1, a wind power rotating mechanism 2, a lifting mechanism 3, a base 4, and a distance adjusting mechanism 5.

[0050] As Figures 2 - 5As shown, an inner lining is provided at the upper part of the inner wall of the chimney body 1. The inner lining includes at least two arc-shaped plates 6 that can be assembled into a ring. In this embodiment, there are four arc-shaped plates 6, and these four arc-shaped plates 6 can be assembled into a ring. The four arc-shaped plates 6 assembled into a ring can block the upper part of the inner wall of the chimney body 1, so as to reduce the corrosion of the upper part of the inner wall of the chimney body 1 by the condensed flue gas.

[0051] As Figures 1 - 2 shown, a wind-driven rotating mechanism 2 is provided at the upper end of the chimney body 1. The wind-driven rotating mechanism 2 includes a support frame 21, a rotation driving member 22, and a support shaft 23. The support frame 21 includes an annular frame 211 and a cross frame 212. The annular frame 211 and the cross frame 212 are installed together. The annular frame 211 can be sleeved on the outer side of the upper end of the chimney body 1, so that the annular frame 211 can rotate around the upper end of the chimney body 1, and the cross frame 212 can be horizontally supported on the upper end surface of the chimney body 1. The rotation driving member 22 includes a plurality of arc-shaped wind blades. All the arc-shaped wind blades are installed with the support frame 21, and all the arc-shaped wind blades are arranged around the annular frame 211. Since the annular frame 211 is arranged around the upper end of the chimney body 1, all the arc-shaped wind blades can also be arranged around the upper end of the chimney body 1. The support shaft 23 is arranged inside the chimney body 1, and the upper end of the support shaft 23 is installed with the middle part of the cross frame 212.

[0052] As Figures 2 - 5 shown, the wind-driven rotating mechanism 2 is used to drive the base 4 to rotate. The base 4 is arranged inside the chimney body 1. The base 4 is provided with a shaft hole 41. The shaft hole 41 is sleeved on the support shaft 23 in the wind-driven rotating mechanism 2. A connection key 42 is installed on the hole wall of the shaft hole 41. A long hole 231 is provided on the side wall of the support shaft 23. The long side of the long hole 231 is arranged along the axial direction of the support shaft 23. The connection key 42 is in vertical sliding fit with the long hole 231.

[0053] The principle of the wind-driven rotating mechanism 2 driving the base 4 to rotate is as follows: The arc-shaped wind blades in the wind-driven rotating mechanism 2 drive the annular frame 211 to rotate around the upper end of the chimney body 1 under the blowing of the wind. The annular frame 211 drives the cross frame 212 to rotate. The cross frame 212 drives the support shaft 23 to rotate. The support shaft 23 drives the base 4 to rotate coaxially. Since the wind-driven rotating mechanism 2 can drive the base 4 by means of wind power, the utilization of green energy is realized, which helps to save energy and protect the environment.

[0054] As Figures 1 - 2As shown in the figure, a lifting mechanism 3 is provided at the upper end of the chimney body 1. The lifting mechanism 3 is used to drive the base 4 to lift. The lifting mechanism 3 includes a winding and unwinding driving member 31 and a towing rope 32. The winding and unwinding driving member 31 can be a servo motor, and the chassis of the servo motor is installed on the cross frame 212 in the support frame 21. The towing rope 32 can be a steel wire rope. The upper end of the towing rope 32 is wound around the output shaft of the servo motor. The lower end of the towing rope 32 passes through the rope passing hole 2121 provided on the cross frame 212, the accommodating cavity 232 provided in the support shaft 23, and the long hole 231 communicated with the accommodating cavity 232 in sequence, and then is tied to the connection key 42 of the base 4.

[0055] The principle of the lifting mechanism 3 driving the base 4 to lift is as follows: When the servo motor serving as the winding and unwinding driving member 31 rotates clockwise, the towing rope 32 wound around the output shaft of the servo motor is released, so that the base 4 suspended by the towing rope 32 slides vertically along the support shaft 23, thereby realizing the descent of the base 4. When the servo motor serving as the winding and unwinding driving member 31 rotates counterclockwise, the towing rope 32 wound around the output shaft of the servo motor is wound up, so that the base 4 suspended by the towing rope 32 slides vertically upward along the support shaft 23, thereby realizing the ascent of the base 4.

[0056] As Figures 2 - 5 shown in the figure, an adjusting mechanism 5 is provided on the base 4. The adjusting mechanism 5 is used to adjust the distance between the end of the arc-shaped plate 6 and the base 4. In this embodiment, the adjusting mechanism 5 includes a first adjusting cylinder 51, a first adjusting rod 52, a first fixing member (not shown in the figure), and a fixing rod 53. The first adjusting cylinder 51 is sleeved on the upper part of the base 4. A first supporting ring 43 for supporting the first adjusting cylinder 51 is installed on the upper part of the base 4. The first adjusting cylinder 51 can rotate around the base 4 on the first supporting ring 43. When it is not necessary to rotate the first adjusting cylinder 51, the first adjusting cylinder 51 and the base 4 can be fixed together by using the first fixing member. The first fixing member can be a fastener such as a bolt or a screw. One end of the first adjusting rod 52 is rotatably connected to the outer wall of the first adjusting cylinder 51 through a pin shaft. The other end of the first adjusting rod 52 is rotatably connected to one end of the arc-shaped plate 6 used for splicing into the inner lining. One end of the fixing rod 53 is fixedly installed at the lower end of the base 4. The other end of the fixing rod 53 is rotatably connected to the end of the arc-shaped plate 6 far from the first adjusting rod 52 through a pin shaft.

[0057] In the normal state, the outer side surface of the arc-shaped plate 6 used for splicing into the inner lining can be integrally attached to the upper part of the inner wall of the chimney body 1, so as to play a protective role in the upper part of the inner wall of the chimney body 1, enabling the condensed flue gas to contact the inner lining first instead of the upper part of the inner wall of the chimney body 1, so as to reduce the corrosion of the condensed flue gas on the upper part of the inner wall of the chimney body 1.

[0058] When it is necessary to clean the inner wall of the chimney body 1, the following operations need to be carried out:

[0059] (1) First, the worker removes the first fixing piece. Then, the worker rotates the first adjusting cylinder 51 counterclockwise, causing the first adjusting cylinder 51 to rotate counterclockwise around the base 4. When the first adjusting cylinder 51 rotates counterclockwise, the first adjusting cylinder 51 drives the first adjusting rod 52 to rotate counterclockwise together, making the end of the arc-shaped plate 6 rotatably connected to the first adjusting rod 52 approach the base 4, and the end of the arc-shaped plate 6 rotatably connected to the fixing rod 53 abut against the inner wall of the chimney body 1. Refer to Figure 6 the state shown, so that the end of the arc-shaped plate 6 abutting against the inner wall of the chimney body 1 can be used to scrape the inner wall of the chimney body 1. Finally, the worker reinstalls the first fixing piece.

[0060] (2) The worker starts the servo motor serving as the winding and unwinding driving member 31, and the output shaft of the servo motor releases the towing rope 32, enabling the base 4, the distance adjusting mechanism 5 on the base 4, and the arc-shaped plate 6 suspended by the towing rope 32 to move downward along the support shaft 23. During the downward movement of the arc-shaped plate 6, the wind-driven rotating mechanism 2 can drive the arc-shaped plate 6 to rotate. Thus, the arc-shaped plate 6 can scrape the inner wall of the chimney body 1 while rotating and moving downward, achieving the cleaning of the inner wall of the chimney body 1.

[0061] From the above process, it can be seen that: in the steel chimney of this embodiment, because all the arc-shaped plates 6 can not only be assembled into a ring-shaped inner lining to protect the upper part of the inner wall of the chimney body 1, but also use the arc-shaped plates 6 to scrape the dirt on the inner wall of the chimney, achieving the cleaning of the inner wall of the chimney body 1. Therefore, the steel chimney of this embodiment can not only clean the inner wall of the chimney body 1, but also relieve the corrosion of the upper part of the inner wall of the chimney body 1 by the condensed flue gas.

[0062] Unexpectedly, the inner lining realizes the dual use of the structure. First, it is used to protect the upper part of the inner wall of the chimney body 1, and second, it is used to scrape the inner wall of the chimney body 1. Thus, there is no need to separately set a scraping strip to scrape the inner wall of the chimney body 1, or no need to separately set an inner lining to protect the upper part of the inner wall of the chimney body 1, which helps to save resources and protect the environment.

[0063] Even more unexpectedly, when the wind-driven rotating mechanism 2 drives the base 4 and the arc-shaped plate 6 on the base 4 to rotate together, the arc-shaped plate 6 can Figure 6 also act as a exhaust fan blade in the state shown, and during the cleaning process, it helps to discharge the dirt cleaned down from the chimney body 1.

[0064] In addition, in the steel chimney of this embodiment, the wind-driven rotating mechanism 2 uses wind power to drive the base 4 and the arc-shaped plate 6 on the base 4 to rotate. Thus, using this green energy of wind power helps to further improve the environmental protection effect.

[0065] In addition, in the steel chimney of this embodiment, the distance adjustment mechanism 5 for adjusting the distance between the end of the arc-shaped plate 6 and the base 4 can achieve the adjustment of all the arc-shaped plates 6 at one time, which is beneficial to improving the adjustment efficiency and thus beneficial to improving the cleaning efficiency of the steel chimney.

[0066] Embodiment 2:

[0067] In this Embodiment 2, the fixing rod 53 in Embodiment 1 is not used. On the basis of Embodiment 1, further improvements are made:

[0068] As Figures 7 - 8 shown, in the steel chimney of this embodiment, the distance adjustment mechanism 5 further includes a second adjustment cylinder 54, a second adjustment rod 55, and a second fixing member (not shown in the figure). The second adjustment cylinder 54 is sleeved on the lower part of the base 4. A second supporting ring 44 for supporting the second adjustment cylinder 54 is installed on the lower part of the base 4. The second adjustment cylinder 54 can rotate around the base 4 on the second supporting ring 44. When it is necessary to stabilize the state of the second adjustment cylinder 54 after rotation, the second fixing member can be used to fix the second adjustment cylinder 54 on the base 4. The second fixing member can also adopt fasteners such as screws or bolts. One end of the second adjustment rod 55 is rotatably connected to the second adjustment cylinder 54 through a pin shaft, and the other end of the second adjustment rod 55 is rotatably connected to the end of the arc-shaped plate 6 away from the first adjustment rod 52 through a pin shaft.

[0069] Figure 9 In the steel chimney of this embodiment, the end of the arc-shaped plate 6 close to the second adjustment rod 55 abuts against the inner wall of the chimney body 1, so that the end of the arc-shaped plate 6 close to the second adjustment rod 55 can be used to scrape the inner wall of the chimney body 1.

[0070] Figure 10 In the steel chimney of this embodiment, the end of the arc-shaped plate 6 close to the first adjustment rod 52 abuts against the inner wall of the chimney body 1, so that the end of the arc-shaped plate 6 close to the first adjustment rod 52 can be used to scrape the inner wall of the chimney body 1.

[0071] When it is necessary to change the arc-shaped plate 6 from Figure 9 to Figure 10When in the state of , the following operations need to be carried out: (1) First, the worker removes the first fixing piece. Then, the worker rotates the first adjusting cylinder 51 clockwise around the base 4. The first adjusting cylinder 51 drives the first adjusting rod 52 to rotate clockwise, so that one end of the arc-shaped plate 6 rotatably connected to the first adjusting rod 52 abuts against the inner wall of the chimney body 1. Finally, the worker reinstalls the first fixing piece to fix the first adjusting cylinder 51 and the base 4 together. (2) First, the worker removes the second fixing piece. Then, the worker rotates the second adjusting cylinder 54 clockwise around the base 4. The second adjusting cylinder 54 drives the second adjusting rod 55 to rotate clockwise, so that one end of the arc-shaped plate 6 rotatably connected to the second adjusting rod 55 approaches the base 4, thus realizing the change from Figures 9 to 10 to the state of .

[0072] It can be seen from the above process that in the steel chimney of this embodiment, after one end of the arc-shaped plate 6 rotatably connected to the first adjusting rod 52 is worn, it can be carried out according to the above Figures 9 to 10 state change, and continue to use one end of the arc-shaped plate 6 rotatably connected to the second adjusting rod 55 to scrape the inner wall of the chimney body 1, which is beneficial to extending the service life of the arc-shaped plate 6, saving the number of replacements of the arc-shaped plate 6, and is beneficial to further saving costs and protecting the environment.

[0073] In addition, unexpectedly, in the steel chimney of this embodiment, the distance between both ends of the arc-shaped plate 6 and the base 4 can be adjusted by using the distance adjusting mechanism 5, so that all the arc-shaped plates 6 can be accommodated inside the chimney body 1 with different inner diameters, and by adjusting the distance between both ends of the arc-shaped plate 6 and the base 4, the arc-shaped plate 6 can be made to scrape the inner wall of the chimney body 1 with different inner diameters, improving the use flexibility.

[0074] Embodiment 3:

[0075] On the basis of Embodiment 2, this Embodiment 3 makes further improvements:

[0076] As Figures 11 - 12 shown, the arc-shaped plate 6 includes a first frame 61, a second frame 62, and a single plate 63. The first frame 61 and the second frame 62 are arranged side by side. A plurality of single plates 63 arranged in parallel are provided between the first frame 61 and the second frame 62. The upper end of the single plate 63 is detachably connected to the first frame 61, and the lower end of the single plate 63 is detachably connected to the second frame 62. Specifically, fasteners such as screws or bolts can be used to realize the detachable connection between the upper end of the single plate 63 and the first frame 61, and fasteners such as screws or bolts can also be used to realize the detachable connection between the lower end of the single plate 63 and the first frame 61. The first frame 61 is rotatably connected to the first adjusting rod 52 through a pin shaft, and the second frame 62 is rotatably connected to the second adjusting rod 55 through a pin shaft.

[0077] With the above settings, when a single board 63 is damaged, the single board 63 can be replaced individually without replacing the entire arc-shaped plate 6, which is conducive to further improving the service life of the arc-shaped plate 6, further saving replacement and maintenance resources and costs, and is conducive to further protecting the environment.

[0078] Further, scraping blades 45 are installed at both the upper and lower ends of the base 4. The scraping blades 45 are in contact with the side wall of the support shaft 23. When the base 4 moves up and down along the support shaft 23, the base 4 can drive the scraping blades 45 to move up and down together, so that the scraping blades 45 can be used to clean the support shaft 23.

[0079] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
