Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a sewage discharge structure of a bottom-blown boiler. Background Art

[0002] my country's boiler industry is neither a "sunrise industry" nor a "sunset industry", but an eternal industry that coexists with mankind, and it is still a growing industry in my country. However, my country's industrial boiler industry and enterprises are also facing various challenges and opportunities. As the main body of market competition, industrial boiler manufacturers should have a clear understanding of their external environment and internal conditions, clarify their market positioning, and manage from a strategic height to do what they should and what they should not. After the boiler operation is completed, it is generally necessary to clean up the dust and debris in the boiler for continued use. However, manual cleaning alone is usually time-consuming and labor-intensive and the effect is not good. For this reason, we need an auxiliary structure to discharge and remove dust from the dust and waste of the boiler.

[0003] For example, a furnace bottom ash cleaning structure for a boiler disclosed in the authorization announcement number CN217057573U includes a furnace body, a mounting frame is fixedly connected to the lower side wall of the furnace body, the side walls on both sides of the mounting frame are provided with sockets and the same grate is inserted into the two sockets, the grate divides the inner wall of the mounting frame into a combustion chamber and a waste collection chamber, the side wall of the combustion chamber is provided with a feed port and a baffle is hinged at the feed port. The furnace bottom ash cleaning structure for a boiler can vibrate the grate after the fuel on the grate is completely burned, so that all the waste on the surface of the grate falls into the waste collection chamber, and the operator does not need to manually knock the grate, which reduces the workload of the operator and can evenly spread the fuel on the grate before the fuel is burned, thereby improving the utilization rate of the fuel and automatically cleaning the waste in the waste collection chamber, and the operator does not need to manually clean it, thus avoiding the problem that the waste will burn the operator's skin. However, the mechanical vibration sewage discharge method adopted by the utility model is easy to cause fatigue and damage to the equipment, which is not conducive to the long-term use of the equipment. For this reason, we proposed a sewage discharge structure for a bottom-blown furnace boiler, which changes the mechanical vibration dust removal to sonic vibration dust removal, greatly reducing the damage of mechanical vibration to the equipment, extending the service life of the boiler equipment, and thus improving the economic benefits of the structure.
