Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] As Figures 1-4 shown, it relates to a boiler anti-blocking device, including box body 1, the top of box body 1 is open design, and the top end of box body 1 is fixed with top plate 5, the upper surface of top plate 5 is fixed with detachable top cover 6, the lower surface of top cover 6 is fixed with spring 8, and the bottom end of spring 8 is fixed with bottom plate 9, the lower surface of bottom plate 9 is fixed with filter screen plate 4, and filter screen plate 4 is slidably connected with the inner wall of box body 1, filter screen plate 4 is inclined design, the side wall of box body 1 is fixed with smoke inlet pipe 2 and smoke outlet pipe 3 respectively, smoke inlet pipe 2 is located on the side close to the lower surface of filter screen plate 4, smoke outlet pipe 3 is located on the side close to the upper surface of filter screen plate 4, the outer side wall of box body 1 is fixed with driving assembly 12 for driving filter screen plate 4 to vibrate up and down, and the inside bottom end of box body 1 is provided with collection box 15.

[0024] The end of smoke inlet pipe 2 away from box body 1 is fixedly connected with the boiler smoke exhaust pipe, and the end of smoke outlet pipe 3 away from box body 1 is connected with heat exchange device.

[0025] The flue gas from the boiler is discharged from the inlet pipe 2 into the box 1, the particulate impurities in the flue gas are blocked by the filter screen plate 4 and located below the filter screen plate 4, most of the particles fall into the collection box 15, and a small part of the particles adhere to the lower surface of the filter screen plate 4. The filtered flue gas enters the heat exchange device from the outlet pipe 3.

[0026] The side wall of the bottom end of the box 1 is provided with a side opening 14, and the side cover 16 is fixed to the side of the collection box 15 close to the side opening 14. The side cover 16 is located outside the box 1 and is fixedly connected with the box 1 by bolts.

[0027] In this embodiment, a sealing strip is arranged between the side cover 16 and the box 1. When it is necessary to clean the particulate impurities in the collection box 15, the bolts between the side cover 16 and the box 1 are disassembled, and then the collection box 15 is pulled out from the inside of the box 1, and the particulate impurities in the collection box 15 can be poured out.

[0028] The driving assembly 12 includes a motor 121 fixed to the outer side wall of the box 1. The output end of the motor 121 is fixedly connected with a driving shaft 122. The driving shaft 122 penetrates through the side wall of the box 1 and is fixedly connected with a cam 123. The cam 123 is located below the filter screen plate 4.

[0033] When it is necessary to disassemble the top cover 6, the internal thread cap 7 is unscrewed, and then the top cover 6 can be disassembled from the upper surface of the top plate 5. The bottom plate 9 and the filter screen plate 4 are pulled out from the top of the box 1 by the spring 8. The bottom plate 9 and the filter screen plate 4 are fixedly connected by bolts, so that the filter screen plate 4 can be disassembled and replaced.

[0034] The top cover 6 is fixedly connected with a handle 13 on the upper surface.

[0035] Working principle: when in use, the flue gas enters the box body 1 from the flue gas inlet pipe 2, the particulate impurities in the flue gas are blocked by the filter screen plate 4 and are located below the filter screen plate 4, most of the particulates fall into the collecting box 15, and a small amount of particulates adhere to the lower surface of the filter screen plate 4. The filtered flue gas enters the heat exchange device from the flue gas outlet pipe 3. During this period, the motor 121 drives the driving shaft 122 and the cam 123 to rotate, when the long end of the cam 123 contacts the lower surface of the filter screen plate 4, the filter screen plate 4 is lifted upward, when the long end of the cam 123 rotates to the side away from the filter screen plate 4, the spring 8 pushes the filter screen plate 4 to drop and reset, so that the filter screen plate 4 reciprocates up and down, the particulate impurities on the lower surface of the filter screen plate 4 fall off, and the filter screen plate 4 is prevented from being blocked.
