[0024] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0025] Embodiment 1:

[0026] A dust removal device for a powder injection pile ash conveying tank comprises an ash conveying tank 10, a dust removal device 20 installed inside the ash conveying tank 10 and capable of removing dust from the inner wall of the ash conveying tank 10 in all directions, and a cleaning device 30 arranged above the dust removal device 20; the ash conveying tank 10 comprises a feed port 11, a tank body 12 for installing the feed port 11, a conical can head 13 detachably connected to the tank body 12, and a discharge port 14 arranged on the can head 13.

[0027] Furthermore, the tank body 12 includes an outer shell 121 , an inner shell 122 disposed on one side of the outer shell 121 , and a heating wire 123 disposed between the inner shell 122 and the outer shell 121 .

[0028] like Figure 1As shown, the dust removal device 20 is installed inside the ash conveying tank 10, and in conjunction with the cleaning device 30, it is mainly used to remove dust and clean the inner wall of the tank body 12, and all attached materials are removed from the inner wall of the tank body 12. At the same time, the ash conveying tank 10 adopts a detachable connection between the tank body 12 and the can head 13. After opening the can head 13, the inner wall of the can head 13 can be manually dusted and cleaned. After the dust removal and cleaning of the tank body 12 and the can head 13 are completed, the can head 13 is installed on the tank body 12 to prevent the attached materials from corroding the inner wall of the ash conveying tank 10; in this process, there are water stains remaining, and the ash conveying tank 10 The inside of the tank 10 cannot receive sunlight, so the water stains cannot be discharged to the outside of the ash conveying tank 10 in time, and the inner wall of the ash conveying tank 10 is corroded by the water stains. Therefore, a tank body 12 with a drying function is adopted. Specifically, a double-layer shell is adopted, namely an outer shell 121 and an inner shell 122. A heating wire 123 is arranged between the outer shell 121 and the inner shell 122. The water stains are converted into water vapor through heat conduction and discharged and dried from the feed port 11 of the tank body 12 or the discharge port 14 on the can 13, which has the effect of thoroughly cleaning the attached materials and preventing the inner wall of the ash conveying tank 10 from being corroded by water stains.

[0029] Furthermore, the dust removal device 20 includes a threaded shaft 21 , a driving device 22 installed on the threaded shaft 21 , and a plurality of dust removal arms 23 installed on the driving device 22 .

[0030] Furthermore, the dust removal arm 23 includes a telescopic rod 231 , a fixed shaft 232 installed on the telescopic rod 231 , and a dust removal roller 233 installed on the fixed shaft 232 .

[0031] Furthermore, the telescopic rod 231 includes a main rod 2311 , a sleeve 2312 sleeved on the main rod 2311 , and a telescopic spring 2313 disposed between the sleeve 2312 and the main rod 2311 .

[0032] like Figures 1 to 4 As shown, the driving device 22 can be a 360-degree circular rotating cylinder, which is installed above the threaded shaft 21 in a threaded connection manner. By connecting with a plurality of dust removal arms 23, the dust removal arms 23 are driven to rotate in a clockwise or counterclockwise manner. While rotating, due to the threaded connection, the dust removal arms 23 can move vertically up and down on the threaded shaft 21.

[0033] The dust removal arm 23 is provided with a pair. The dust removal roller 233 on the dust removal arm 23 presses against the inner wall of the tank body 12 under the rebound force of the telescopic spring 2313. During the rotation, the dust removal roller 233 performs friction movement on the inner wall of the tank body 12. The dust removal roller 233 may be provided with materials with a cleaning function such as steel bristles. When the dust removal roller 233 rubs against the inner wall of the tank body 12, the materials and dust attached to the inner wall of the tank body 12 are removed.

[0034] The attached material has a certain thickness, so the telescopic rod 231 is used. Under the action of the telescopic spring 2313, the telescopic rod 231 not only enables the dust removal roller 233 to press against the inner wall of the tank body 12, but also has a certain regulating effect when encountering attached materials of a certain thickness, so as not to be stuck by the attached materials and cause the device to be unable to operate.

[0035] Furthermore, the cleaning device 30 includes a water pump 31 , a water pipe 32 connected to the water pump 31 , and a water outlet 33 connected to the water pipe 32 .

[0036] Furthermore, the water outlet 33 includes a ring pipe 331 and a plurality of water outlet pipes 332 arranged on the ring pipe 331 .

[0037] Furthermore, the water outlet pipes 332 are distributed in an array on the annular pipe 331 , and the pipe openings face the inner wall of the tank body 12 .

[0038] like Figures 1 to 4 As shown, the existing ash conveying tank 10 generally adopts dry dust removal, which not only fails to thoroughly remove the dust from the inner wall of the ash conveying tank 10, but also causes the material dust to float inside the ash conveying tank 10 and cannot be discharged. Therefore, the present invention adopts a cleaning device 30, which draws water from a water source through the water pump 31, and then pumps water into the water pipe 32, and flows into the water outlet 33 through the water pipe 32. The water outlet 33 is provided with an annular pipe 331. Under the pressure of the water pump 31, the water fills the entire annular pipe 331, and then is transferred to the water outlet pipe 332, and is sprayed out from the nozzle of the water outlet pipe 332.

[0039] The water outlet pipe 332 is distributed in an array through the ring pipe 331. The number of arrays can be set according to actual needs to ensure that the water outlet pipe 332 can spray water all over the inner wall of the ash conveying tank 10 to prevent material dust from flying inside the tank body 12 during the dust removal process of the dust removal device 20. Therefore, the nozzle of the water outlet pipe 332 is facing the inner wall of the tank body 12.

[0040] like Figures 1 to 4 As shown, when the ash conveying tank 10 is dusted, the cleaning device 30 is first started to wet the ash conveying tank 10. After the dust removal device 20 cleans the inner wall of the tank body 12 and the inner wall of the can 13 is manually cleaned, the can 13 is installed, and the cleaning device 30 is started again to clean the inner wall of the ash conveying tank 10. Waste water is discharged from the discharge port 14. Finally, the heating wire 123 of the tank body 12 is started to dry the inside of the ash conveying tank 10.

[0041] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
