Description

Technical Field

[0001] This utility model relates to the field of boiler soot blowing technology, and specifically to a soot blowing device. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy. Also known as a power plant boiler, a boiler in a power plant is a medium to large-sized boiler that provides a specified quantity and quality of steam to a steam turbine. It is one of the main thermal power plants and is often paired with a steam turbine generator set of a certain capacity, primarily used for power generation. After a period of use, ash accumulates on the heating surface of a boiler, affecting its heating efficiency. Therefore, soot blowing devices are needed to clean the ash from the boiler.

[0003] Existing soot blowing devices typically operate statically, blowing soot from a fixed location onto the boiler's inner wall. This limited blowing area negatively impacts the blowing efficiency. Furthermore, the use of external gas for soot blowing means that the lower temperature of the external gas entering the boiler can affect the internal temperature. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings and provide a soot blowing device that improves the soot blowing effect.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a soot blowing device, comprising: A mounting plate for placing the top of the boiler, wherein support columns are symmetrically installed at the bottom end of the mounting plate; A rotating cylinder is rotatably mounted on the mounting plate, with one end extending into the boiler. The soot blowing pipe is telescopically adjustable and installed inside the rotating cylinder, with one end extending out of the rotating cylinder to blow soot from the boiler at different heights. The gas injection unit, mounted on the mounting plate, is used to inject extracted boiler internal gas into the soot blowing pipe.

[0006] Furthermore, the soot blowing tube includes a rotating cylinder inserted inside the rotating cylinder, a movable cylinder threaded onto the outer wall of the rotating cylinder and slidably connected to the inner wall of the rotating cylinder, a connecting cylinder disposed at the bottom end of the movable cylinder, a soot blowing tube disposed at the bottom end of the connecting cylinder, and soot blowing holes equally spaced on the outer wall of the soot blowing tube for blowing out gas.

[0007] Furthermore, the connecting cylinder is an inverted frustum-shaped structure, and the inner diameter of the connecting cylinder decreases from top to bottom.

[0008] Furthermore, the mounting plate is provided with a drive mechanism for driving the rotating cylinder and the rotating drum to rotate. The drive mechanism includes a bevel gear one fixedly sleeved on the rotating cylinder, a bevel gear two fixedly sleeved on the rotating cylinder and located above the bevel gear one, a motor disposed on the mounting plate, and a bevel gear three mounted on the output end of the motor and meshing with the bevel gear one and the bevel gear two.

[0009] Furthermore, limit blocks are symmetrically installed on the outer wall of the movable cylinder, and a limit groove is provided on the inner wall of the rotating cylinder for the limit blocks to slide and fit.

[0010] Furthermore, the gas injection unit includes a gas pump installed on the top of the mounting plate, a gas injection pipe located at the output end of the gas pump and extending into the interior of the rotating cylinder for gas injection, and a gas extraction pipe located at the input end of the gas pump and extending into the interior of the boiler.

[0011] Furthermore, one end of the suction pipe is threadedly connected to a mounting cap, and a filter plate is provided inside the mounting cap.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By setting up an injection unit, the present invention facilitates the extraction of gas from inside the boiler and injection into the soot blowing pipe. Then, the soot blowing pipe blows air into the boiler for soot blowing. At the same time, because the soot blowing pipe is rotatably installed inside the rotating cylinder, it can move up and down inside the boiler while rotating to blow soot, realizing soot blowing operations at different heights inside the boiler, increasing the soot blowing range inside the boiler and improving the soot blowing effect.

[0020] like Figure 1-3 As shown, the present invention provides a soot blowing device, comprising: Mounting plate 1 is used to place the top of the boiler, and support columns 2 are symmetrically installed at the bottom end of the mounting plate 1; A rotating cylinder 3 is rotatably mounted on the mounting plate 1, with one end of it extending into the boiler. The soot blowing pipe is telescopically adjustable and is installed inside the rotating cylinder 3, with one end extending out of the rotating cylinder 3 to blow soot from the boiler at different heights. The gas injection unit, mounted on the mounting plate 1, is used to inject extracted boiler internal gas into the soot blowing pipe.

[0021] In use, the gas injection unit works to extract gas from inside the boiler and inject it into the soot blowing pipe. Then, air is blown into the boiler through the soot blowing pipe to perform soot blowing. At the same time, because the soot blowing pipe is rotatably installed inside the rotating cylinder 3, the soot blowing pipe can move up and down inside the boiler while rotating to blow soot, so that soot blowing can be performed at different heights inside the boiler, increasing the soot blowing range inside the boiler and improving the soot blowing effect.

[0022] It should be noted that the soot blowing tube includes a rotating cylinder 4 inserted inside the rotating cylinder 3, a movable cylinder 5 threaded onto the outer wall of the rotating cylinder 4 and slidably connected to the inner wall of the rotating cylinder 3, a connecting cylinder 6 located at the bottom end of the movable cylinder 5, a soot blowing tube 7 located at the bottom end of the connecting cylinder 6, and soot blowing holes 8 evenly spaced on the outer wall of the soot blowing tube 7 for blowing out gas. With this design, when gas is injected into the rotating cylinder 4, it enters the movable cylinder 5, then sequentially enters the connecting cylinder 6 and the soot blowing tube 7, and is discharged through multiple soot blowing holes 8, facilitating soot blowing operations in different directions, effectively increasing the soot blowing range, and thus improving soot blowing efficiency.

[0023] It should be noted that the connecting cylinder 6 is an inverted frustum-shaped structure, and the inner diameter of the connecting cylinder 6 decreases from top to bottom. This design, because the inner diameter of the connecting cylinder 6 decreases from top to bottom, can increase the pressure, accelerate the gas injection speed, and thus increase the soot blowing efficiency.

[0024] It should be noted that the mounting plate 1 is provided with a drive mechanism for driving the rotating cylinder 4 and the rotating cylinder 3 to rotate. The drive mechanism includes a bevel gear 14 fixedly sleeved on the rotating cylinder 3, a bevel gear 2 15 fixedly sleeved on the rotating cylinder 4 and located above the bevel gear 14, a motor 16 disposed on the mounting plate 1, and a bevel gear 3 17 mounted on the output end of the motor 16 and meshing with the bevel gear 14 and the bevel gear 2 15. This design, through the design of the drive mechanism, effectively enables the rotating cylinder 4 to rotate inside the rotating cylinder 3, achieving opposite rotation between the rotating cylinder 3 and the rotating cylinder 4. Simultaneously, the movable cylinder 5 drives the connecting cylinder 6 and the soot blowing cylinder 7 to rise and fall during rotation, increasing the soot blowing operation to different heights of the boiler and thus increasing soot blowing efficiency. By starting the motor 16, the motor drives the bevel gear 17 to rotate. Through the meshing of the bevel gear 17 with the first bevel gear 14 and the second bevel gear 15, the first bevel gear 14 and the second bevel gear 15 rotate in opposite directions. The first bevel gear 14 drives the rotating cylinder 3 to rotate, and the second bevel gear 15 drives the rotating cylinder 4 to rotate. Through the sliding action between the movable cylinder 5 and the rotating cylinder 3, and the threaded relationship between the movable cylinder 5 and the rotating cylinder 4, the movable cylinder 5 rises and falls outside the rotating cylinder 4. Furthermore, the movable cylinder 5, through the connecting cylinder 6, drives the height adjustment of the soot blowing cylinder 7, facilitating soot blowing operations to different heights inside the boiler, effectively increasing the soot blowing range and thus improving soot blowing efficiency.

[0025] It should be noted that limiting blocks 9 are symmetrically installed on the outer wall of the movable cylinder 5, and limiting grooves 10 are provided on the inner wall of the rotating cylinder 3 for the limiting blocks 9 to slide and fit. This design, through the limiting action of the limiting blocks 9 and the limiting grooves 10, ensures that the rotation of the rotating cylinder 3 synchronously drives the movable cylinder 5 to rotate. When the movable cylinder 5 and the rotating cylinder 3 rotate in opposite directions, the movable cylinder 5 and the rotating cylinder 4 will also rotate in opposite directions. Since the movable cylinder 5 and the rotating cylinder 4 are threadedly connected, the movable cylinder 5 can extend and retract outside the rotating cylinder 4. This allows the movable cylinder 5 to drive the sootblowing cylinder 7 to adjust its height via the connecting cylinder 6, facilitating sootblowing operations at different heights inside the boiler, effectively increasing the sootblowing range and improving sootblowing efficiency.

[0026] It should be noted that the gas injection unit includes an air pump 12 installed at the top of the mounting plate 1, an injection pipe 11 located at the output end of the air pump 12 and extending into the rotating cylinder 4 for gas injection, and an extraction pipe 13 located at the input end of the air pump 12 and extending into the boiler. With this design, by activating the air pump 12, the air pump 12 draws gas from inside the boiler through the extraction pipe 13, and then the extracted gas is injected into the rotating cylinder 4 through the injection pipe 11, achieving gas circulation inside the boiler and preventing the injection of externally cooled gas from affecting the boiler's internal temperature.

[0027] It should be noted that one end of the exhaust pipe 13 is threadedly connected to a mounting cover 18, and a filter plate 19 is provided inside the mounting cover 18. This design, through the design of the filter plate 19, effectively filters particulate matter inside the boiler.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
