[0002] A biomass boiler is a device that uses biomass energy for heating or power generation. Biomass refers to the general term for organic matter from plants or animals, including wood, straw, husks, sawdust, domestic garbage, livestock and poultry manure, etc. Biomass boilers burn these biomass materials and convert them into heat energy for heating, hot water production or power generation.

[0006] Furthermore, the cleaning component includes a water pump, which is fixedly connected to the middle of the rear side of the water tank, the water pump output end is fixedly connected to a delivery pipe, the top of the delivery pipe is fixedly connected to an annular pipe, and the bottom of the annular pipe is fixedly connected to a plurality of evenly distributed nozzles.

[0007] Furthermore, the buckle assembly includes two springs, which are respectively fixedly connected to the front and rear sides of the left part of the water tank, and the two springs are fixedly connected with a clamping block on the sides facing each other, and the two clamping blocks are fixedly connected with a pull rod on the sides away from each other.

[0008] Furthermore, a filter plate is slidably connected to the middle of the water tank, and slots are provided on both the front and rear sides of the left part of the filter plate, and the two blocks are respectively embedded and connected in the two slots on the opposite sides.

[0009] Furthermore, both the front and rear sides of the left part of the water tank are provided with limiting grooves, and the separated sides of the two springs are respectively fixedly connected in the two limiting grooves.

[0010] Furthermore, a drain pipe is fixedly connected to the boiler on the side facing the water tank.

The motor 3 transmits power to the brush 5 at the bottom through the connecting frame 4. Multiple brushes 5 are connected to the bottom of the connecting frame 4 and rotated by the drive of the motor 3. These brushes 5 are in contact with the inner wall of the boiler 1 and are used to clean the dust and carbon deposits on the inner wall. The feed port 6 is located at the top of the right side of the boiler 1, which is used to put biomass fuel for the boiler 1 to burn and generate heat energy. The ash discharge port 7 is located at the bottom of the right side of the boiler 1, which is used to discharge the dust generated by combustion.

The drain pipe 13 is fixedly connected to the side of the boiler 1 facing the water tank 9, which is used to discharge the wastewater generated after the boiler 1 is cleaned.

[0025] Reference Figure 1-3 The cleaning component 11 includes a water pump 111, which is fixedly connected to the middle of the rear side of the water tank 9. The output end of the water pump 111 is fixedly connected to a delivery pipe 112, the top of the delivery pipe 112 is fixedly connected to an annular pipe 113, and the bottom of the annular pipe 113 is fixedly connected to a plurality of evenly distributed nozzles 114.

[0026] Specifically, the cleaning component 11 is located at the rear side of the water tank 9 and is used for cleaning the boiler 1. The water pump 111 is a key part of the cleaning component 11 and is fixedly connected to the middle of the rear side of the water tank 9. Its main function is to provide hydraulic power to transport water from the water tank 9 to the nozzle 114 for cleaning the inner wall of the boiler 1. The delivery pipe 112 is connected to the output end of the water pump 111 and is responsible for guiding the water flow delivered by the water pump 111 to the cleaning area. The annular pipe 113 is located at the top of the delivery pipe 112 and can effectively guide the water flow to the nozzle 114. A plurality of evenly distributed nozzles 114 are fixedly connected to the bottom of the annular pipe 113. The nozzle 114 is responsible for spraying water onto the inner wall of the boiler 1, and cooperates with the brush 5 to clean carbon deposits and dust to maintain the efficiency of the boiler 1.

[0027] Reference Figure 1 , Figure 2 and Figure 4The buckle assembly 12 includes two springs 121, which are respectively fixedly connected to the front and rear sides of the left part of the water tank 9. Limiting grooves 15 are provided on the front and rear sides of the left part of the water tank 9. The two springs 121 are respectively fixedly connected in the two limiting grooves 15 on the separated sides. The two springs 121 are fixedly connected with a clamping block 122 on the opposite sides. The two clamping blocks 122 are fixedly connected with a pull rod 123 on the separated sides. A filter plate 14 is slidably connected to the middle part of the water tank 9. The filter plate 14 is provided with clamping grooves 16 on the front and rear sides of the left part. The two clamping blocks 122 are respectively embedded in the two clamping grooves 16 on the opposite sides.

[0028] Specifically, the buckle assembly 12 is located on the front and rear sides of the left part of the water tank 9, and is used to fix the connection between the water tank 9 and the filter plate 14 to ensure that the connection between them is firm. The two springs 121 are fixedly connected to the front and rear sides of the left part of the water tank 9 to provide elastic support for the block 122. The limiting groove 15 is used to limit the position of the spring 121. The block 122 is fixedly connected to a pull rod 123 on one side to adjust the position of the block 122. The middle part of the water tank 9 is slidably connected to the filter plate 14, which is used to filter impurities in the waste water after cleaning the boiler 1. The filter plate 14 is provided with slots 16 on the front and rear sides of the left part. The two blocks 122 are respectively embedded in these slots 16 on the opposite sides to ensure that the filter plate 14 is firmly connected to the water tank 9.

[0029] Working principle: First, put the biomass fuel into the boiler 1, and then burn it through the feed port 6 to generate heat energy. As the combustion process proceeds, dust and carbon deposits will be generated on the inner wall of the boiler 1. The motor 3 is started, and the motor 3 drives the brush 5 to rotate through the connecting frame 4. The brush 5 abuts against the inner wall of the boiler 1 to clean the dust and carbon deposits on the inner wall. During the cleaning process, the water pump 111 draws water from the water tank 9, and transports the water to the annular pipe 113 through the delivery pipe 112. The annular pipe 113 guides the water flow to the nozzle 114. The nozzle 114 sprays the water flow onto the inner wall of the boiler 1, and cooperates with the brush 5 to thoroughly clean the inner wall of the boiler 1.

[0030] After cleaning, the wastewater is discharged into the water tank 9 through the drain pipe 13. The filter plate 14 at the bottom of the water tank 9 can filter out impurities in the wastewater to ensure environmental pollution during the wastewater discharge process. After long-term use, a large amount of impurities will accumulate on the surface of the filter plate 14, thereby affecting the filtering effect. Pulling the pull rod 123 drives the block 122 to shrink into the limit groove 15, and the block 122 is separated from the left front and rear sides of the filter plate 14. The filter plate 14 can be slid out for cleaning and maintenance.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
