[0002] A biomass boiler is a type of boiler. A boiler that uses biomass energy as fuel is called a biomass boiler. It is divided into biomass steam boilers, biomass hot water boilers, biomass hot air furnaces, biomass thermal oil furnaces, vertical biomass boilers, horizontal biomass boilers, etc. The waste residue after combustion in the biomass boiler will be stored in the slag storage port, and the slag storage port can be opened and cleaned regularly in the later stage.

[0003] In order to prevent the accumulated slag in the boiler from leaking when it is discharged to the transfer vehicle, a slag guide trough is usually set below the accumulated slag outlet. Since the waste slag may contain metal substances due to the iron particles accidentally mixed in the biomass fuel, the accumulated slag may cause damage to the recovery device during the subsequent recycling process. Therefore, a biomass boiler accumulated slag cleaning device is needed. When the accumulated slag in the boiler is cleaned and discharged, the iron particles therein can be removed, so that the accumulated slag in the boiler can be de-ironized during the cleaning process, thereby facilitating the subsequent recycling and utilization of the accumulated slag.

[0023] Example 2:

[0024] Figure 1-3 The utility model shows a biomass boiler slag cleaning device according to an embodiment of the present invention, which includes a cleaning tank 1 fixed below the slag port of the biomass boiler: a horizontal plate 2 is fixedly installed on the inner wall of the cleaning tank 1, a motor 3 and a horizontal rod 4 are fixedly installed on the surface of the horizontal plate 2 by bolts, a column 5 is welded on the surface of the horizontal rod 4, a slip ring 6 is slidably connected to the surface of the column 5, a moving rod 7 is welded to the bottom of the slip ring 6, a rake rod 8 is provided at the bottom of the moving rod 7, the output shaft of the motor 3 is fixedly connected to a support rod 9 through a flange, and the surface of the support rod 9 is fixedly connected to the shaft Rod 10, a slot plate 11 is welded to the top of the moving rod 7, and an inner cavity of the cleaning tank 1 is provided with an iron-absorbing plate 13.

[0025] Working principle: When the present invention is used, the user discharges the waste slag from the boiler slag outlet through the cleaning slot 1, and at the same time opens the support rod 9 to drive the support rod 9 to rotate, so that the support rod 9 moves the slot plate 11 through the shaft rod 10, and then the slot plate 11 drives the moving rod 7 to move back and forth.

At this time, the iron particles of the slag during the moving process can be adsorbed by the iron-absorbing plate 13, so that the iron particles in the slag in the boiler can be removed when the slag is cleaned and discharged, and the slag in the boiler can be de-ironized during the cleaning process, which is convenient for the subsequent recycling and utilization of the slag.

At this time, the iron particles in the slag during the moving process can be adsorbed by the iron-absorbing plate 13, so that the iron particles in the slag in the boiler can be removed when the slag is cleaned and discharged, and the slag in the boiler can be de-ironized during the cleaning process, thereby facilitating the subsequent recycling and utilization of the slag.
