[0002] A circulating fluidized bed boiler is a type of boiler that uses fluidized combustion technology to achieve efficient fuel combustion. Its core feature is the formation of a fluidized bed in the furnace, which allows the fuel particles to be suspended and fully mixed under the action of the rising airflow, thereby achieving combustion. Due to its high efficiency and environmental protection characteristics, it has been widely used in power generation, industrial heating and district heating.

[0003] The slag discharge pipe of a circulating fluidized bed boiler is prone to blockage due to various factors during use. For example, when the particle size of the coal entering the furnace is too large, it is easy to form a blockage in the slag discharge pipe; the coal particles are not completely burned in the furnace and generally continue to burn when entering the slag discharge pipe, causing local high-temperature coking and producing coke blocks, which leads to blockage; some detached casting materials fall into the coal chamber, and the large pieces of material cause congestion and blockage during discharge; generally, the staff use steel drills and steel pipes to poke and crush the blocked coal slag clumps, but the coal slag can easily burn the staff during the processing process.

[0004] Therefore, those skilled in the art have proposed a circulating fluidized bed boiler slag discharge device to solve the problems raised in the background art. Utility Model Content

[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] Example 1

[0026] As attached Figure 1 To the attached Figure 3 As shown, the utility model provides a circulating fluidized bed boiler slag discharge device, including an adjustment component 100, a mobile compartment 101, wherein the mobile compartment 101 can move the device to the bottom of the slag discharge pipe, a slag receiving port 102 connected to the mobile compartment 101, when the device scrapes the slag discharge pipe, the scraped waste slag falls into the mobile compartment 101 through the slag receiving port 102 for easy collection, and a lifting component 103 arranged in the mobile compartment 101, wherein the lifting component 103 is used to adjust the height of the processing component 200 in the slag discharge pipe;

[0027] The processing component 200 includes a drive motor 201 provided on the lifting assembly 103, wherein the drive motor 201 is a power source. When the drive motor 201 is working, it drives the rotating rod 202 to rotate. The rotating rod 202 is fixedly connected to the output end of the drive motor 201, and the processing assembly 203 connected to the rotating rod 202. The rotation of the rotating rod 202 drives the processing assembly 203 to rotate and expand, thereby performing a scraping operation. The shielding shed 204 is fixedly connected to the rotating rod 202, wherein the shielding shed 204 can guide the waste residue to be scattered in the mobile compartment 101 to avoid accumulation.

[0028] The processing assembly 203 includes a synchronous plate 203a fixedly connected to the rotating rod 202, wherein the synchronous plate 203a is fixedly connected to the rotating rod 202, a scraper 203b rotatably connected to the synchronous plate 203a, and when the rotating rod 202 rotates, the synchronous plate 203a and the scraper 203b rotate synchronously, a connecting groove 203c is opened on the surface of the scraper 203b, wherein the connecting groove 203c is opened on the negative side of the scraper 203b, which can prevent waste residue from entering and affecting the rotation of the auxiliary plate 203d, an auxiliary plate 203d rotatably connected to the connecting groove 203c, wherein when the scraper 203b rotates, the inclination angle of the scraper 203b and the auxiliary plate 203d changes due to the influence of centrifugal force, thereby controlling the opening angle and scraping angle of the scraper 203b, and a lifting plate 203e rotatably connected to the auxiliary plate 203d, and when the inclination angle of the scraper 203b and the auxiliary plate 203d changes, the lifting plate 203e slides up and down along the rotating rod 202.

[0029] Specifically, the lifting plate 203e is slidably connected to the rotating rod 202. When the rotation speed of the rotating rod 202 increases, the lifting plate 203e slides upward along the rotating rod 202. When the rotation speed of the rotating rod 202 is stable, the height of the lifting plate 203e is stable. When the rotation speed of the rotating rod 202 decreases, the lifting plate 203e slides downward along the rotating rod 202. The lifting plate 203e is located above the shielding canopy 204, where the shielding canopy 204 can limit the lowest point of the lifting plate 203e.

[0030] Furthermore, the shielding canopy 204 is a downwardly inclined annular plate, and the size of the lower end of the shielding canopy 204 is larger than the driving motor 201 , wherein the shielding canopy 204 can provide shielding for the driving motor 201 , thereby ensuring the service life of the driving motor 201 .

[0031] As can be seen from the above, the device is moved to the bottom of the slag discharge pipe by moving the box car 101, and the slag discharge pipe is aligned with the slag receiving port 102, and the height of the processing component 200 in the slag discharge pipe is adjusted by the lifting component 103; the driving motor 201 is started, and the driving motor 201 drives the rotating rod 202, the synchronous plate 203a, the scraper 203b and the auxiliary plate 203d to rotate synchronously, and the scraper 203b performs the scraping work. At the same time, due to the influence of centrifugal force, the scraper 203b and the auxiliary plate 203d are moved. The inclination angle of 3d changes, and the lifting plate 203e slides on the rotating rod 202, and then the opening angle and scraping angle of the scraper 203b can be controlled by the rotation speed of the driving motor 201. When the device scrapes the slag pipe, the scraped waste slag falls into the mobile car 101 through the slag collecting port 102, and is guided by the shielding shed 204 to be scattered in the mobile car 101 to avoid accumulation. Finally, the door of the mobile car 101 is opened to collect the waste slag.

[0032] Example 2:

[0033] As attached Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that the lifting assembly 103 includes a guide cylinder 103a fixedly installed in the mobile car 101, and a lifting cylinder 103b slidingly connected to the guide cylinder 103a, wherein the lifting cylinder 103b slides up and down along the guide cylinder 103a to adjust the height of the processing component 200, and the driving motor 201 is fixedly connected to the upper surface of the lifting cylinder 103b.

[0034] Specifically, the lifting assembly 103 also includes an installation chamber 103c connected to the guide cylinder 103a, wherein the installation chamber 103c provides protection for the lifting motor 103d, and the lifting motor 103d is fixedly installed on the lower surface of the interior of the installation chamber 103c, wherein the lifting motor 103d is a power source, a driving bevel gear 103e fixedly connected to the output end of the lifting motor 103d, a threaded rod 103f rotatably connected to the lower surface of the interior of the guide cylinder 103a, and a transmission bevel gear 103g fixedly connected to the threaded rod 103f. When the lifting motor 103d works, it drives the driving bevel gear 103e to rotate, and the driving bevel gear 103e drives the transmission bevel gear 103g to rotate, thereby driving the threaded rod 103f to rotate, and an anti-slip plate 103h fixedly connected to the upper surface of the threaded rod 103f, wherein the anti-slip plate 103h is used to limit the maximum upward movement distance of the lifting cylinder 103b.

[0035] Furthermore, the driving bevel gear 103e is engaged with the transmission bevel gear 103g, and the threaded rod 103f is threadedly connected to the lifting cylinder 103b. When the threaded rod 103f rotates, the lifting cylinder 103b slides along the guide cylinder 103a under the influence of the thread.

[0036] As can be seen from the above, when the lifting motor 103d is started, the lifting motor 103d drives the driving bevel gear 103e to rotate. Since the driving bevel gear 103e is engaged with the transmission bevel gear 103g, the transmission bevel gear 103g also rotates, thereby driving the threaded rod 103f to rotate. The lifting cylinder 103b is affected by the thread and will slide up and down along the guide cylinder 103a according to the rotation direction of the threaded rod 103f, thereby adjusting the working height of the processing component 200.
