DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is combined with the drawings and example, and the utility model is further explained in detail.

[0030] Example 1

[0031] In this embodiment, as Figures 1-6 As shown, a combustion furnace sealing structure includes a combustion furnace body 101 and a feed inlet 102 disposed on one side of the combustion furnace body 101. A connecting ring 103 is fixedly connected to the feed inlet 102. A furnace door 104 is hinged to the surface of the combustion furnace body 101. The connecting ring 103 is adapted to the size and specifications of the furnace door 104. A handle is provided on the side of the furnace door 104 away from the feed inlet 102 to facilitate opening the furnace door 104.

[0032] A sealing ring 105 is provided on the side of the furnace door 104 near the feed inlet 102. When the furnace door 104 is closed with the connecting ring 103, the sealing ring 105 can be inserted into the connecting ring 103 at the feed inlet 102 for sealing, which facilitates further improvement of the sealing performance of the combustion furnace body 101. The sealing ring 105 is provided with a rotating mechanism 200 to increase the sealing effect of the sealing ring 105. A fastening mechanism 300 is provided on the outer surface of the furnace door 104 to reduce the gap between the furnace door 104 and the connecting ring 103. The fastening mechanism 300 tightly clamps the furnace door 104 and the connecting ring 103 together to prevent heat loss.

[0033] Among them, such as Figures 3-6 As shown, the rotating mechanism 200 includes a turntable 201 rotatably connected to the furnace door 104. The other end of the turntable 201 is connected to a locking assembly to facilitate the positioning of the turntable 201 and the sealing arc plate 206. Several connecting rods 202 are fixedly installed on the side wall of the turntable 201. Each connecting rod 202 has a rotating rod 203 rotatably connected to its end. The other end of the rotating rod 203 is movably connected to a limiting block 204. Several limiting grooves 205 are symmetrically formed on the surface of the furnace door 104. The limiting block 204 is slidably disposed inside the limiting groove 205. A sealing arc plate 206 is fixedly connected to one side of the limiting block 204. The sealing arc plate 206 is connected to the furnace door 104. The door 104 is slidably connected to the surface. When the user turns the handle 207, the turntable 201 rotates, causing the turntable 201 to rotate the connecting rod 202. This allows the connecting rod 202 to push the rotating rod 203 to move. The rotating rod 203 then causes the limiting block 204 to slide inside the limiting groove 205, thereby pushing the sealing ring 105 to shift outward.

[0035] As shown in Figure 1 and Figure 6 As shown, the locking assembly comprises a rotating handle 207 fixedly connected with the rotating disc 201, the rotating handle 207 and the rotating disc 201 are provided with sealing pads at the connecting position with the furnace door 104, the rotating handle 207 is rotatably connected with the furnace door 104, and the other end of the rotating handle 207 extends to the outside of the furnace door 104, the surface of the rotating handle 207 is provided with a locking bolt 208, a plurality of screw holes are formed on the surface of the furnace door 104, and the other end of the locking bolt 208 is inserted into one of the screw holes, so as to fix the position of the rotating handle 207, and then the positions of the rotating disc 201 and the sealing arc-shaped plate 206 are limited.

[0036] As shown in Figure 3 and Figure 4 As shown, a plurality of guide blocks 209 are fixedly arranged on the side of the furnace door 104 close to the feeding port 102, the guide blocks 209 play a guiding role on the sealing arc-shaped plate 206, and can cooperate with the sealing arc-shaped plate 206 to reduce the probability of heat leakage between the two ends of the sealing arc-shaped plate 206.
