[0011] Compared with the prior art, the present utility model has the following beneficial effects:
[0012] 1. In this biomass steam boiler flue gas waste heat recovery device, after the flue gas is filtered by the filter plate, the filtered flue gas can be discharged through the discharge port, thus reducing the problem of air pollution caused by direct discharge due to excessive impurities in the flue gas. When the filter plate has been used for too long, due to the rectangular groove provided on the outer wall of the rectangular shell, when the moving assembly works, the connecting block can drive the clamping plate to slide through the rectangular groove. Since the controller is electrically connected to the motor and the motor, when the filter plate needs to be replaced, by pressing the controller, the controller can drive the motor to start working, and then the motor can drive the moving assembly to start working. At this time, the moving assembly drives the filter plate to slide out of the inner cavity of the rectangular shell, so that the used filter plate can be replaced.

In this biomass steam boiler flue gas waste heat recovery device, when the motor starts to work, the motor can drive the first disc to rotate, and then the first disc can drive the conveyor belt to rotate the second disc. When the second disc rotates, the second disc can drive the rectangular plate to rotate. Since the first cleaning brush and the second cleaning brush are respectively fixedly installed at the top of the rectangular plate, the first cleaning brush and the second cleaning brush can clean the copper pipe, avoiding the problem that the outer wall of the copper pipe is attached with oil stains due to the long-term exposure of the copper pipe to the flue gas, which affects the heating efficiency of the copper pipe.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figure 1 - Figure 5 , a flue gas waste heat recovery device for a biomass steam boiler, including an outer shell 1, a circular ring 2 is fixedly installed at the bottom of the outer shell 1, a pipeline 3 is fixedly installed at the top of the outer shell 1, a rectangular shell 4 is fixedly installed at the top of the pipeline 3, a controller 5 is fixedly installed on the outer wall of the rectangular shell 4, a mobile component 6 is arranged on the inner wall of the rectangular shell 4, a support frame 7 is fixedly installed at the bottom of the circular ring 2, a cleaning component 8 is arranged at the top of the support frame 7, a copper pipe 9 is fixedly installed on the inner wall of the outer shell 1, and a filter plate 10 is arranged on the inner wall of the mobile component 6.
[0024] In the above structure, since a pipeline 3 is fixedly installed at the top of the outer shell 1, when the waste heat enters the inner cavity of the outer shell 1 through the circular ring 2, at this time, the waste heat can heat the copper pipe 9, and the excess heat can enter the pipeline 3 along the outer shell 1 and then enter the inner cavity of the rectangular shell 4 through the pipeline 3. At this time, the waste heat can be filtered by the mobile component 6, and the filtered waste heat is discharged into the air, thereby reducing the pollution of the air caused by waste heat impurities.
[0025] In a preferred implementation mode: The controller 5 is electrically connected to the motor 606 and the motor 801, and a rectangular groove is opened on the outer wall of the rectangular shell 4, and the outer wall of the connecting block 602 is slidably connected to the inner wall of the rectangular groove.
[0026] In the above structure, a rectangular groove is formed in the outer wall of the rectangular shell 4, so that when the moving component 6 is working, the connecting block 602 can drive the clamping plate 601 to slide through the rectangular groove. The controller 5 is electrically connected to the motor 606 and the motor 801. When the filter plate 10 needs to be replaced, by pressing the controller 5 at this time, the controller 5 can drive the motor 606 to start working, so that the motor 606 can drive the moving component 6 to start working. At this time, the moving component 6 drives the filter plate 10 to slide out of the inner cavity of the rectangular shell 4, so that the used filter plate 10 can be replaced.
[0027] In a preferred embodiment: The moving component 6 includes a clamping plate 601. A connecting block 602 is fixedly installed on the outer wall of the clamping plate 601. A gear 603 is fixedly installed on the outer wall of the connecting block 602 away from the clamping plate 601. A rack 604 is engaged with the outer wall of the gear 603. A fixing plate 605 is provided on the outer wall of the rack 604. A motor 606 is fixedly installed on the outer wall of the fixing plate 605.
[0028] In a preferred embodiment: The power output shaft of the motor 606 is fixedly installed at the bottom of the gear 603. A rectangular groove is formed in the outer wall of the clamping plate 601, and a slider is fixedly installed on the outer wall of the fixing plate 605. The outer wall of the slider is slidably connected to the inner wall of the rectangular groove.
[0029] In the above structure, when the motor 606 starts to work, the motor 606 can drive the gear 603 to rotate on the outer wall of the rack 604. At this time, the gear 603 can move linearly on the inner wall of the rack 604. Thus, the gear 603 can drive the connecting block 602 to slide the clamping plate 601 on the inner wall of the rectangular shell 4. At this time, the clamping plate 601 can drive the filter plate 10 to slide, so that the filter plate 10 can be separated from the inner wall of the rectangular shell 4, and thus the filter plate 10 can be replaced.
[0030] In a preferred embodiment: The cleaning component 8 includes a motor 801. A disc one 802 is fixedly installed on the power output shaft of the motor 801. A conveyor belt 803 is rollingly connected to the outer wall of the disc one 802. A disc two 804 is rollingly connected to the outer wall of the conveyor belt 803. A cylinder 805 is rotatably connected to the inner wall of the disc two 804. A rectangular plate 806 is fixedly installed at the top of the cylinder 805. A cleaning brush one 807 and a cleaning brush two 808 are respectively fixedly installed at the top of the rectangular plate 806.
[0031] In a preferred embodiment: The top of the disc two 804 is fixedly installed with the bottom of the rectangular plate 806. The bottom of the cylinder 805 is fixedly installed with the top of the support frame 7. The outer wall of the cleaning brush two 808 is in contact with the inner ring of the copper pipe 9. The outer wall of the cleaning brush one 807 is in contact with the outer ring of the copper pipe 9.
[0032] In the above structure, when the motor 801 starts to work, the motor 801 can drive the first disc 802 to rotate, so that the first disc 802 can drive the conveyor belt 803 to rotate the second disc 804. When the second disc 804 is rotating, the second disc 804 can drive the rectangular plate 806 to rotate. Since the cleaning brush one 807 and the cleaning brush two 808 are respectively fixedly installed on the top of the rectangular plate 806, the cleaning brush one 807 and the cleaning brush two 808 can clean the copper tube 9.
[0033] Working principle: The controller 5 is electrically connected to the motor 606 and the motor 801. When the filter plate 10 needs to be replaced, by pressing the controller 5, the controller 5 can drive the motor 606 to start working. When the motor 606 starts to work, the motor 606 can drive the gear 603 to rotate on the outer wall of the rack 604. At this time, the gear 603 can move linearly on the inner wall of the rack 604. Thus, the gear 603 can drive the connecting block 602 to slide the clamping plate 601 on the inner wall of the rectangular housing 4. At this time, the clamping plate 601 can drive the filter plate 10 to slide, so that the used filter plate 10 can be replaced. By pressing the controller 5, the controller 5 controls the motor 801. When the motor 801 starts to work, the motor 801 can drive the first disc 802 to rotate, so that the first disc 802 can drive the conveyor belt 803 to rotate the second disc 804. When the second disc 804 is rotating, the second disc 804 can drive the rectangular plate 806 to rotate. Since the cleaning brush one 807 and the cleaning brush two 808 are respectively fixedly installed on the top of the rectangular plate 806, the cleaning brush one 807 and the cleaning brush two 808 can clean the copper tube 9.
