Description

Technical Field

[0001] The utility model relates to the technical field of boiler ash cleaning, in particular to a boiler ash cleaner for a power plant. Background Art

[0002] Power plant boilers, also known as "power plant boilers", refer to medium and large boilers in power plants that provide a specified amount and quality of steam to steam turbines. They are one of the main thermal equipment in thermal power plants. They are often matched with steam turbine generator sets of a certain capacity and are mainly used for power generation, but in some special occasions they can also be used for external heat supply.

[0003] After searching, the patent announcement number CN208967822U discloses a cleaning device for a power plant boiler, including a slag cleaning box, the top of the slag cleaning box is fixedly connected to the boiler body, the top and bottom of the interior of the slag cleaning box are fixedly connected to a vertical plate, the left side wall of the vertical plate is fixedly connected to a motor, the right side wall of the interior of the slag cleaning box is fixedly connected to a bearing, and the right output end of the motor is fixedly connected to a spiral feeding rod. The cleaning device for a power plant boiler sucks the dust particles generated by the slag discharge inside the slag cleaning box into the cleaning box through a straw, and some larger dust particles fall into the ash drawer, which is convenient for centralized treatment after storage. The filter is easy to disassemble. When taking out the ash drawer, the two side card plates are pushed to push the spring, so that the filter can be taken out from the two side card plates, which is convenient for later maintenance, saving time and effort, and is conducive to promotion and popularization.
