The arc surface of the circular tube (4) on the left side is fixedly connected to a water inlet head (6), and the arc surface of the circular tube (4) on the right side is fixedly connected to a water outlet head (5). A filter assembly (2) is provided at the left end of the box (1). The filter assembly (2) includes a filter tube (21) fixedly connected to the left end of the box (1). A filter screen (22) is fixedly connected to the inner wall of the filter tube (21). A rotating rod (23) is provided at the left end of the filter screen (22). A steel brush bristle (26) is fixedly connected to the right end of the rotating rod (23). A driving mechanism (24) is provided on the arc surface of the filter tube (21). The driving mechanism (24) is used to drive the rotating rod (23) to rotate.

2. A gas-fired boiler heat exchanger as defined in claim 1, characterised in that: The drive mechanism (24) includes a mounting ring (244) fixedly connected to the left end of the filter screen (22). The inner wall of the mounting ring (244) is provided with a first bevel gear (243) rotatably connected by a bearing. The surface of the first bevel gear (243) is meshed with a second bevel gear (242). The first bevel gear (243) and the rotating rod (23) are fixed.

3. A gas-fired boiler heat exchanger as defined in claim 2, characterised in that: The arc surface of the filter tube (21) is provided with a drive shaft (241) rotatably connected by a bearing. The drive shaft (241) is used to connect an external motor. The drive shaft (241) is fixed to the second bevel gear (242).

4. A gas-fired boiler heat exchanger as defined in claim 3, characterised in that: The arc surface of the filter tube (21) is fixedly connected to a protective cover (25), which is used to protect the first bevel gear (243) and the second bevel gear (242).

5. A gas-fired boiler heat exchanger as claimed in claim 4, characterised in that: A connecting block (27) is fixedly connected to the inner wall of the first bevel gear (243). The connecting block (27) is inserted into the rotating rod (23). The rotating rod (23) and the connecting block (27) are detachably connected by screws.

6. A gas-fired boiler heat exchanger as defined in claim 5, characterised in that: The filter tube (21) has a disassembly port (28) on its arc surface, and a disassembly block (210) is provided on the inner wall of the disassembly port (28).

7. A gas-fired boiler heat exchanger as defined in claim 6, characterised in that: The filter tube (21) has a second mounting rod (29) fixedly connected to both sides of its arc surface, and the disassembly block (210) has a first mounting rod (211) fixedly connected to both ends. The second mounting rod (29) and the first mounting rod (211) are fixed by screws.

8. A gas-fired boiler heat exchanger as defined in claim 7, characterised in that: A sealing gasket is provided between the filter tube (21) and the disassembly block (210).
