[0009] An exhaust pipe is fixedly connected to the purification box;

[0010] There are four filter plates fixedly connected inside the purification box;

[0011] The cleaning mechanism is arranged inside the purification box. The cleaning mechanism can clean the exhaust gas purification equipment inside the purification box to avoid blockage, thereby ensuring the normal purification of the exhaust gas by the purification box.

[0012] Preferably, the cleaning mechanism comprises a driving shaft, to which a pushing block is fixedly connected;

[0024] Preferably, both sides of the separation box are fixedly connected with concave-shaped connecting ears, and both sides of the collection box are fixedly connected with transverse U-shaped fixing ears;

The longer end of the fixed ear horizontal plate is fixedly connected to the surface of the collecting box, and the shorter end of the fixed ear horizontal plate is slidably connected to the inside of the connecting ear.

[0026] Compared with the prior art, the beneficial effects of the utility model are:

[0027] 1. In the biomass fuel carbonization and gasification combustion furnace, when the exhaust gas enters the interior of the purification box through the exhaust gas treatment pipeline, the exhaust gas contacts four filter plates respectively with the flow of air. At this time, the filter plates filter and adsorb harmful substances in the exhaust gas according to their materials and arrangement orders, and then the purified exhaust gas is discharged through the exhaust pipe. When the exhaust gas enters the interior of the purification box from the exhaust gas treatment pipeline, the potential energy generated by the gas flow acts on the pushing block directly below it. At this time, the pushing block is forced to drive the driving shaft and the cleaning brush to rotate, and then the cleaning brush cleans the surface of the filter plate, so that the filter plate can be effectively prevented from being blocked, thereby ensuring the purification effect of the purification box on the exhaust gas.

[0028] 2. The biomass fuel carbonization and gasification combustion furnace has a guide plate set up, so the dust and impurities cleaned by the cleaning brush fall onto the guide plate through the gap between the two sealing blocks. At this time, the dust and impurities slide through the inclined surface of the guide plate to the end of the separation plate away from the guide ring. As the dust and impurities continue to accumulate, the end of the separation plate away from the guide ring is affected by gravity and rotates under the support of the positioning shaft. Therefore, the guide ball slides along the arc-shaped slide groove and squeezes the elastic component. Therefore, the impurities and dust accumulated on the separation plate fall into the interior of the collection box when the separation plate rotates, thereby completing the separation and collection of the dust and impurities.

[0050] The collecting box 7 slides inside the fixing ear 9 and the connecting ear 8, so that the collecting box 7 and the separation box 6 can be quickly disassembled and assembled. Therefore, when a large amount of impurities are accumulated inside the collecting box 7, it can be easily removed, thereby facilitating the dumping of the impurities.

[0051] Further, the cleaning mechanism includes a driving shaft 10, to which a pushing block 11 is fixedly connected;

[0052] The push block 11 is located directly below the connection between the exhaust gas treatment pipeline 3 and the purification box 5;

[0053] The driving shaft 10 passes through the four filter plates 13 and is rotatably connected thereto. A cleaning brush 12 is fixedly connected to the driving shaft 10. The cleaning brush 12 is respectively located on both sides of the four filter plates 13 and is in contact with the surfaces thereof.

[0054] The push block 11 is composed of a circular ring and a plurality of inclined panels.

[0055] When the exhaust gas enters the interior of the purification box 5 through the exhaust gas treatment pipe 3, as the air flows, the exhaust gas contacts the four filter plates 13 respectively. At this time, the filter plates 13 filter and adsorb harmful substances in the exhaust gas according to their materials and arrangement orders, and then the purified exhaust gas is discharged through the exhaust pipe 4. When the exhaust gas enters the interior of the purification box 5 from the exhaust gas treatment pipe 3, the potential energy generated by the gas flow acts on the push block 11 directly below it. At this time, the push block 11 is forced to drive the drive shaft 10 and the cleaning brush 12 to rotate, and then the cleaning brush 12 cleans the surface of the filter plate 13, so that the filter plate 13 can be effectively prevented from being blocked, thereby ensuring the purification effect of the purification box 5 on the exhaust gas;

[0056] Furthermore, two sealing blocks 14 are fixedly connected to the interior of the purification box 5, and the upper surfaces of the two sealing blocks 14 are both inclined surfaces;

[0057] A gap is left between the two sealing blocks 14;

[0058] When the cleaning brush 12 cleans the filter plate 13, the cleaned dust and impurities fall into the interior of the separation box 6 through the gap between the two sealing blocks 14;

[0059] Furthermore, the interior of the separation box 6 is fixedly connected with an inclined guide plate 15, and the guide plate 15 can guide the dust and impurities that fall into the interior of the separation box 6;

[0060] A semicircular guide ring 18 is fixedly connected inside the separation box 6;

[0066] By setting the guide plate 15, the dust and impurities cleaned by the cleaning brush 12 fall onto the guide plate 15 through the gap between the two sealing blocks 14. At this time, the dust and impurities slide through the inclined surface of the guide plate 15 to the end of the separation plate 16 away from the guide ring 18. As the dust and impurities continue to accumulate, the end of the separation plate 16 away from the guide ring 18 is affected by gravity and rotates under the support of the positioning shaft 17. Therefore, the guide ball 19 slides along the arc-shaped slide groove 2 and squeezes the elastic component 20.

[0067] Working principle: When the exhaust gas enters the purification box 5 through the exhaust gas treatment pipe 3, the exhaust gas contacts the four filter plates 13 respectively as the air flows. At this time, the filter plates 13 filter and adsorb harmful substances in the exhaust gas according to their materials and arrangement orders, and then the purified exhaust gas is discharged through the exhaust pipe 4. When the exhaust gas enters the purification box 5 from the exhaust gas treatment pipe 3, the potential energy generated by the gas flow acts on the push block 11 directly below it. At this time, the push block 11 is driven by the force to drive the drive shaft 10 and the cleaning brush 12 to rotate, and then the cleaning brush 12 cleans the surface of the filter plate 13, so that the filter plate 13 can be effectively prevented from being blocked, thereby ensuring the purification effect of the purification box 5 on the exhaust gas;

[0068] By setting the guide plate 15, the dust and impurities cleaned by the cleaning brush 12 fall onto the guide plate 15 through the gap between the two sealing blocks 14. At this time, the dust and impurities slide through the inclined surface of the guide plate 15 to the end of the separation plate 16 away from the guide ring 18. As the dust and impurities continue to accumulate, the end of the separation plate 16 away from the guide ring 18 is affected by gravity and rotates under the support of the positioning shaft 17. Therefore, the guide ball 19 slides along the arc-shaped slide groove 2 and squeezes the elastic component 20. Therefore, the impurities and dust accumulated on the separation plate 16 fall into the inside of the collection box 7 when the separation plate 16 rotates, thereby completing the separation and collection of dust and impurities.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
