This structure is simple to operate and improves the replacement efficiency of the filter 13.

[0023] like Figure 3 As shown, a filter screen 13 is fixedly installed on the inner wall of the installation frame 11, and a sealing ring 15 is fixedly connected to one side of the outer wall of the installation frame 11. The outer wall of the sealing ring 15 is clamped with the inner wall of the installation groove 16. The sealing ring 15 can reduce the exhaust gas generated by the push plate furnace from escaping from the gap between the installation frame 11 and the air inlet pipe 4.
