The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0023] According to a specific embodiment of the present disclosure, a boiler sealing device is provided, which includes: a flexible seal 100, the flexible seal 100 having a first end 110 and a second end 120 arranged opposite to each other, the first end 110 surrounding the bottom of the boiler 1000 and being installed on the side wall of the boiler 1000 through a connecting assembly 200, the second end 120 surrounding the top of the slag hopper 2000 and being installed on the side wall of the slag hopper 2000 through the connecting assembly 200, the boiler sealing device also includes an elastic member 300, the elastic member 300 is configured to enable the connecting assembly 200 to be pressed against the flexible seal 100, so that the first end 110 and the second end 120 are respectively pressed against the side wall of the boiler 1000 and the side wall of the slag hopper 2000.

[0024] Through the above technical solution, in the boiler sealing device provided by the present disclosure, the first end 110 and the second end 120 of the flexible seal 100 respectively surround the bottom of the boiler 1000 and the top of the hopper 2000. In other words, the flexible seal 100 can be installed between the boiler 1000 and the hopper 2000 and seal the area between the boiler 1000 and the hopper 2000 to prevent air leakage from the bottom of the boiler 1000. In addition, the first end 110 and the second end 120 are respectively installed on the sidewalls of the boiler 1000 and the hopper 2000. In other words, the first end 110 and the second end 120 partially overlap with the sidewalls of the boiler 1000 and the hopper 2000, respectively, thus ensuring the sealing effect of the flexible seal 100. In addition, the provision of the elastic member 300 ensures that the first end 110 and the second end 120 are respectively in close contact with the sidewalls of the boiler 1000 and the hopper 2000. In this way, the sealing effect of the flexible sealing member 100 can be further ensured. In summary, the boiler sealing device can seal the boiler bottom with good sealing performance.

[0025] In the boiler sealing device provided by the present disclosure, the connection assembly 200 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 2 As shown in , the connection assembly 200 may include a mounting frame 210, a pressing plate 220, and a connecting member 230. One end of the mounting frame 210 may be mounted on the side wall of the boiler 1000 or the slag hopper 2000, and the other end may extend away from the side wall and be formed with a mounting portion 211. The connecting member 230 may sequentially penetrate the pressing plate 220, the flexible seal 100, and the mounting portion 211 to securely mount the pressing plate 220 on the mounting portion 211. The elastic member 300 may be disposed between the pressing plate 220 and the connecting member 230. The elastic member 300 may be configured to press the pressing plate 220 against the mounting portion 211. In this way, the elastic member 300 may exert a force on the pressing plate 220 that causes the pressing plate 220 to move toward the mounting portion 211, thereby ensuring that both sides of the flexible seal 100 along its thickness direction are respectively in close contact with the pressing plate 220 and the mounting portion 211, thereby ensuring the sealing effect of the flexible seal 100. In addition, the other end of the mounting frame 210 extends away from the side wall, that is, the mounting portion 211, the pressure plate 220 and the connecting member 230 can be spaced apart from the boiler 1000 or the slag hopper 2000, thereby preventing workers from being accidentally scalded during the assembly of the flexible seal 100.

[0026] In the boiler sealing device provided by the present disclosure, the mounting frame 210 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 2As shown in , the mounting frame 210 may include a first frame 212 and a second frame 213 connected to each other. The first frame 212 may be arranged in contact with the side wall, and the second frame 213 may extend perpendicular to the side wall. The end of the second frame 213 facing away from the first frame 212 may be bent upward to form a mounting portion 211. The first frame 212 is arranged in contact with the side wall, thereby ensuring a seal between the mounting frame 210 and the side wall. Combined with the above, the flexible seal 100 is also tightly attached to the mounting portion 211, thereby ensuring a seal between the mounting frame 210 and the flexible seal 100. In summary, the boiler sealing device has an effective sealing effect on the bottom of the boiler 1000. Furthermore, the first frame 212 is arranged in contact with the side wall, thereby increasing the contact area between the mounting frame 210 and the side wall, thereby improving the stability of the mounting frame 210. In the present disclosure, the mounting bracket 210 can be installed on the side wall in any suitable manner. As an exemplary embodiment, the mounting bracket 210 can be fixed to the side wall by welding or the like, which not only ensures the sealing effect between the mounting bracket 210 and the side wall, but also ensures the stability of the mounting bracket 210. In other embodiments, the mounting bracket 210 can also be detachably installed on the side wall by bolts or other means, which makes it easy to replace the mounting bracket 210.

[0027] In the boiler sealing device provided by the present disclosure, the connecting member 230 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 2 As shown in , the connecting member 230 may include a threaded rod 231 and a pressure block 232 fixed to one end of the threaded rod 231. The threaded rod 231 may sequentially pass through the pressure plate 220, the flexible seal 100 and the mounting portion 211 to drive the pressure plate 220 to press against the mounting portion 211. The threaded rod 231 may be formed with an external thread, and the mounting portion 211 may be formed with an internal thread. In this way, the threaded rod 231 may be directly threadedly mounted on the mounting portion 211, or a nut may be connected to the threaded rod 231. In this way, the bite force of the thread can ensure that the pressure plate 220 is pressed tightly against the mounting portion 211, thereby ensuring that the flexible seal 100 can be respectively pressed against the pressure plate 220 and the mounting portion 211 on both sides along its own thickness direction.

[0028] In the boiler sealing device provided by the present disclosure, the elastic member 300 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 2As shown in , the elastic member 300 can be constructed as a compression spring, which can be sleeved on the threaded rod 231 and arranged between the pressure block 232 and the pressure plate 220. In this way, by continuously screwing in the threaded rod 231, the threaded rod 231 can drive the pressure block 232 to move toward the pressure plate 220, so that the pressure block 232 and the pressure plate 220 are respectively pressed against the two ends of the compression spring. At this time, continuing to screw in the threaded rod 231 can compress the compression spring and generate elastic force to push the pressure plate 220 to press the flexible seal 100 between the pressure plate 220 and the mounting portion 211, thereby ensuring the sealing between the flexible seal 100 and the mounting frame 210.

[0029] In the boiler sealing device provided herein, the pressing block 232 can be constructed in any suitable manner. As an exemplary embodiment, the end surface of the pressing block 232 facing away from the threaded rod 231 can be recessed inward to form a hexagonal socket. This facilitates the operator's use of a hexagonal wrench to rotate the connector 230, providing convenient operation.

[0030] In the boiler sealing device provided herein, the number of mounting brackets 210 and pressure plates 220 can be multiple and arranged in a one-to-one correspondence. Each first bracket 212 is shaped to conform to a portion of the sidewall, allowing the mounting brackets 210 and pressure plates 220 to be arranged around the sidewall through assembly, thereby facilitating assembly. Furthermore, each mounting bracket 210 and pressure plate 220 can be connected to a plurality of connectors 230 and elastic members 300 to ensure that the flexible seal 100 is in close contact with the mounting portion 211 and pressure plate 220 around its perimeter.

[0031] In the boiler sealing device provided herein, the flexible seal 100 can be constructed in any suitable manner. As an exemplary embodiment, the flexible seal 100 may include a flexible sealing body, with both sides of the flexible sealing body in the thickness direction being covered with a layer of metal mesh. The flexible sealing body may include at least one of a fluororubber fiberglass cloth layer, a stainless steel wire mesh layer, and a silicone fluororubber layer. The metal mesh design can prevent the mounting bracket 210 or the pressure plate 220 from abrading the flexible sealing body, thereby further ensuring the sealing effect of the flexible seal 100 and increasing the service life of the flexible seal 100.

[0032] Insulation material can be filled between the fluororubber fiberglass cloth layer and the stainless steel mesh layer, as well as between the stainless steel mesh layer and the silicone fluororubber layer. High-temperature aluminum silicate felt can be used as the insulation material. High-temperature aluminum silicate felt has excellent high-temperature resistance and thermal insulation properties, thereby isolating heat from boiler 1000. Furthermore, high-temperature aluminum silicate felt is thermally shock-resistant, thereby isolating vibration transmission and eliminating noise within boiler 1000.

[0033] According to the second aspect of the present disclosure, Figure 1 As shown in , a boiler system is provided, which includes a boiler 1000, a slag hopper 2000 and the above-mentioned boiler sealing device, and the flexible seal 100 can be arranged between the boiler 1000 and the slag hopper 2000. Therefore, the boiler system has all the above-mentioned advantages, so they are not repeated here.

[0034] In the boiler system provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 1 As shown in FIG, a guide plate 400 may be further provided at the bottom of the boiler 1000. One end of the guide plate 400 may be connected to the bottom wall of the boiler 1000, and the other end may extend downward toward the interior of the boiler 1000. In this way, the design of the guide plate 400 can prevent slag from the boiler 1000 from moving toward the flexible seal 100, thereby increasing the service life of the flexible seal 100.

[0035] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.
