Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust equipment, in particular to a biomass boiler smoke exhaust machine. Background Art

[0002] The smoke exhauster is an important part of the biomass boiler system. It is mainly responsible for effectively and safely exhausting the smoke generated during the combustion process out of the boiler. During the operation of the biomass boiler, the smoke generated by the combustion is effectively guided to the flue under the action of the smoke exhauster and discharged through the chimney. The smoke exhauster can generate enough negative pressure to make the smoke flow smoothly and avoid accumulation inside the boiler, thereby ensuring the normal operation of the boiler and the safe discharge of the smoke. In addition, some parts can be intelligently adjusted according to the operating status of the boiler and the emission of smoke, which can improve the operating efficiency of the boiler, and also help save energy and reduce emissions, reduce pollution to the environment, so as to achieve the best smoke exhaust effect;

[0003] After a period of use, the smoke generated by biomass combustion contains a variety of complex components, such as dust, tar, and incompletely burned particles. These substances will gradually accumulate on the fan blades due to the driving and cooling effects of the airflow during the operation of the smoke exhaust fan. As a result, they will increase the weight of the fan blades, increase the operating load of the smoke exhaust fan, and may cause the motor to overheat or be damaged. In addition, the presence of attachments will change the aerodynamic performance of the fan blades and reduce their smoke exhaust efficiency, thereby affecting the overall operation of the boiler. Since the fan blade structure inside the smoke exhaust fan is fixed on the carrier plate and the open disassembly and assembly process of the fan casing is cumbersome, the fan blade cannot be cleaned conveniently.

[0022] like Figure 3 As shown, the connecting plates 9 located at both sides of the fan blades 8 are fixedly installed with guide rails 11, and the transverse cross-section of the guide rails 11 is a T-shaped structure. Through the arrangement of the two guide rails 11, the scraper 10 can be movably installed on one side of the connecting plate 9 and placed on the outer surface of the fan blade 8;

[0023] like Figure 4 As shown, a first slide groove 12 is provided on the side of the fan blade 8 facing away from the connecting plate 9. With the first slide groove 12 provided on the side of the fan blade 8, the scraper 10 can be made more stable when moving;

[0024] like Figure 3-Figure 5As shown, a first slider 13 is fixedly installed on one side of the scraper 10, and two second slide grooves 14 are provided on one side of the first slider 13. A plurality of balls 15 are rotatably installed on both sides of the second slide grooves 14.
