[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-4 This embodiment provides a boiler internal slag crushing device, including a fixed bracket 1 installed on the inner wall of the boiler. A connecting plate 2 is fitted inside the fixed bracket 1, and a drive rail 3 is fitted on the connecting plate 2. A movable plate 4 is fitted on the drive rail 3, and a telescopic rod 5 is fitted below the movable plate 4. The telescopic rod 5 is fixedly connected to a matching bracket 6, which is installed at the top of a slag processing component 7. Slag crushing components 8 are fitted at both ends of the slag processing component 7. This device is installed inside the boiler and fixed to the boiler inner wall by the fixed bracket 1. Then, through the drive rail 3 and the telescopic rod 5, the slag processing component 7 and the slag crushing components 8 are driven to crush the slag.

[0025] Furthermore, the slag processing component 7 includes a slag dust collection chamber 101, a main storage chamber 102, a cooperating turntable 103, a drive arm 104, a dust pump 105, and a connecting pipe 106. The slag dust collection chamber 101 is located at the center of the slag processing component 7, and the main storage chamber 102 is located inside the slag dust collection chamber 101. Dust pumps 105 are installed on both the left and right sides of the slag dust collection chamber 101, and connecting pipes 106 are installed on the dust pumps 105. The connecting pipes 106 are connected to the main storage chamber 102. Cooperating turntables 103 are installed at both the left and right ends of the slag dust collection chamber 101. Drive arms 104 are installed on the cooperating turntables 103, and slag crushing components 8 are installed on the drive arms 104.

[0026] Furthermore, a dust collection interface is provided at the bottom of the slag dust collection chamber 101. The dust collection interface is connected to the inside of the main storage chamber 102, and an anti-backflow buckle is provided inside the dust collection interface. The slag processing component 7 operates through a dust collection pump 105, which sucks the crushed slag blocks below the device into the main storage chamber 102 for collection through the dust collection interface below the main storage chamber 102, thereby improving the efficiency of boiler internal cleaning. At the same time, the anti-backflow buckle at the dust collection interface can prevent slag blocks from leaking out of the main storage chamber 102 and causing slag block residue inside the boiler.

[0027] Furthermore, the slag crushing component 8 includes a crushing output disc 201, a counterweight 202, a main rotating blade 203, and independent crushing units 204. The crushing output disc 201 is connected to the drive arm 104, and a drive motor is mounted on the drive arm 104. The output end of the drive motor is coaxially connected to the crushing output disc 201. The counterweight 202 is mounted on the outer side of the crushing output disc 201, and the main rotating blade 203 is coaxially mounted on the lower side of the crushing output disc 201. Multiple evenly arranged independent crushing units 204 are mounted on the main rotating blade 203. The slag crushing component 8 can crush larger slag blocks. By driving the main rotating blade 203 to rotate on a fixed axis through the crushing output disc 201, and simultaneously using the independent crushing units 204 mounted on the main rotating blade 203, the crushing efficiency of the slag blocks can be improved, and the working time for crushing the slag blocks can be reduced.

[0028] Furthermore, a high-manganese alloy steel drill bit with a uniform taper is provided on the outer side of the independent crushing unit 204. Compared with probes made of other materials, high-manganese alloy steel has stronger impact resistance and hardness; at the same time, when crushing coal blocks, high-manganese alloy steel can exhibit better wear resistance, thereby improving the service life of the independent crushing unit 204.

[0029] The main storage silo 102 includes an outer support frame 301, a push-pull storage silo 302, and a transition silo 303. The outer support frame 301 is connected to the slag dust collection silo 101. Multiple symmetrically distributed push-pull storage silos 302 are arranged inside the outer support frame 301. A transition silo 303 is located on the outer side of each push-pull storage silo 302, and the transition silo 303 is connected to a connecting pipe 106. The push-pull storage silo 302 design inside the main storage silo 102 improves the efficiency of disassembling the overall components and reduces the complexity of handling the device during use, during the cleaning of the internal slag blocks.

[0030] Furthermore, a dust baffle 9 is provided below the slag handling component 7, and the dust baffle 9 is positioned outside the dust suction interface. The dust baffle 9 can block the outside of the dust suction interface, thereby further improving the efficiency of the dust suction interface in sucking up slag.

[0031] Furthermore, the fixed bracket 1 is fixedly connected to the inner wall of the boiler by bolts.

[0032] Furthermore, the connection between the connecting plate 2 and the drive rail 3 is secured by a groove. During assembly, the dimensions of the connecting plate 2 can be adjusted according to the internal conditions of the boiler, thus adapting to installation work within the boiler with different parameters.

[0033] Furthermore, a micro motor is installed inside the movable plate 4, and the telescopic rod 5 is controlled to extend and retract via the micro motor. By changing its length, the telescopic rod 5 adjusts the position of the mating bracket 6 below, thereby adapting to different processing conditions.
