[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0021] Example like Figure 1 and Figure 2 As shown, the pusher furnace door of this utility model includes a furnace door assembly 1 and a paddle assembly 2. The paddle assembly 2 is used to connect the pusher paddle. One end of the paddle assembly 2 is sealed, and the other end is sealed to the lower outer side of the furnace door assembly 1. A heat-insulating bracket 3 is provided at the connection between the furnace door assembly 1 and the paddle assembly 2 to achieve a sealed connection between the pusher paddle and the furnace door assembly 1. The inner side of the furnace door assembly 1 is used to seal the furnace opening of the furnace tube equipment. The paddle assembly 2 is connected to the pusher drive mechanism. When the pusher drive mechanism drives the paddle assembly 2 to move horizontally, the pusher paddle enters and exits the furnace tube equipment. In this embodiment, the heat-insulating bracket 3 adopts a combination of 316 stainless steel bracket and high-temperature resistant fluororubber, which can both provide support for the pusher paddle and ensure the seal between the pusher paddle and the furnace door assembly 1.

[0022] It should be noted that the boat-pushing drive mechanism can adopt conventional settings in the art, and the connection between the paddle assembly 2 and the boat-pushing drive mechanism can also adopt conventional settings in the art. For example, the boat-pushing drive mechanism includes a cantilever assembly and a horizontal boat-pushing module. The side of the paddle assembly 2 can be connected to the cantilever assembly through a clamp, and the cantilever assembly is then connected to the horizontal boat-pushing module to realize the horizontal reciprocating movement of the paddle assembly 2.

[0023] In this embodiment, the furnace door assembly 1, the paddle assembly 2, and the boat-pushing drive mechanism are connected as a whole. After the boat is loaded, the furnace door can seal the furnace opening of the furnace tube equipment, eliminating the need for the boat-pushing component to retract, thus reducing the risk of the boat-pushing paddle damaging the inner wall of the furnace tube. Simultaneously, a heat-insulating bracket 3 is installed at the connection between the furnace door assembly 1 and the paddle assembly 2 to achieve a sealed connection between the boat-pushing paddle and the furnace door assembly 1, ensuring the sealing requirements inside the furnace tube. It also provides heat insulation to prevent heat loss from the furnace tube, improving the operational safety of the boat-pushing drive mechanism and the paddle assembly 2.

[0024] In this embodiment, an elastic adjustment component is provided between the furnace door assembly 1 and the paddle assembly 2. The elastic adjustment component is used to achieve a flexible connection between the furnace door assembly 1 and the paddle assembly 2. Figure 5 and Figure 6As shown, the elastic adjustment assembly includes a guide rod 4, a spring 5, a mounting sleeve 6, a top plate 7, a mounting base plate 8, and an adjusting screw 9. The guide rod 4 is fixed to the furnace door assembly 1, the mounting base plate 8 is fixed to the paddle assembly 2, the mounting sleeve 6 is connected to the mounting base plate 8, the top plate 7 is nested inside the mounting sleeve 6, the adjusting screw 9 is threaded to the mounting base plate 8 and extends through the mounting base plate 8 into the mounting sleeve 6, abutting against the top plate 7, one end of the spring 5 abuts against the guide rod 4, and the other end of the spring 5 abuts against the top plate 7. When the adjusting screw 9 is turned to push the top plate 7, the top plate 7 compresses or releases the spring 5 to achieve elastic force adjustment of the spring 5. The elastic force generated by the spring 5 provides preload force to the furnace door assembly 1 to prevent the furnace door assembly 1 from shifting and improve the fitting accuracy between the furnace door assembly 1 and the furnace tube equipment.

[0030] In this embodiment, the fastening and adjusting assembly 200 includes an L-shaped paddle clamping block 202, which is disposed inside the paddle sleeve 201. The paddle sleeve 201 has a clear hole 208 on its side wall, and the paddle clamping block 202 has a threaded blind hole 209. A screw is passed through the clear hole 208 to connect to the threaded blind hole 209, thus connecting the screw to the paddle clamping block 202. When the propeller extends into the paddle sleeve 201, the paddle clamping block 202 directly contacts the side of the propeller. Tightening the screw pushes the paddle clamping block 202 to clamp the propeller within the paddle sleeve 201.

[0031] Furthermore, the fastening and adjusting assembly 200 also includes a blind flange 203, a flange weldment 204, and a clamp 205. The flange weldment 204 is welded and fixed to the side of the propeller sleeve 201, and the aperture 208 is located inside the flange weldment 204.
