[0027] The special term "exemplary" here means "serving as an example, embodiment, or illustration". Any embodiment described as "exemplary" here does not have to be construed as superior to or better than other embodiments.
[0028] In addition, for better illustration of the present application, numerous specific details are given in the following detailed embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means, and elements well - known to those skilled in the art are not described in detail so as to highlight the gist of the present application.
[0029] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a cracking furnace door is installed on the furnace body 1 and is used to block the feed inlet 101 formed on the furnace body 1. The cracking furnace door includes:
[0030] The first sealing door 2 is rotatably installed on the furnace body 1 through the first rotating member 3.
[0031] Wherein, a protrusion A is formed at the feed inlet 101, and the protrusion A is arranged in an annular or frame - shaped structure. A protrusion B is formed on the side of the first sealing door 2 facing the feed inlet 101. The shape of the protrusion B is adapted to the shape of the protrusion A, and a slot is formed at the protrusion B. When the first sealing door 2 blocks the feed inlet 101, the protrusion A is inserted into the slot, thereby increasing the sealing performance of the block. Preferably, a flexible sealing member is arranged in the slot, and the flexible sealing member includes but is not limited to heat - insulating cotton, graphite packing, etc.
[0032] A fixing member is used to connect the furnace body 1 and the first sealing door 2 and is used to lock the first sealing door 2 after the first sealing door 2 blocks the feed inlet 101.
[0033] It further includes at least one receiving bracket 102 fixed on the furnace body 1 and located on both sides of the first sealing door 2 respectively, and an anti - detachment wheel 204 rotatably installed on the first sealing door 2. After the first sealing door 2 seals the feeding port 101, it abuts against the receiving bracket 102.
[0034] In this embodiment, by arranging the receiving bracket 102, after the first sealing door 2 is closed, an upward supporting force is generated on the anti - detachment wheel 204, thereby effectively eliminating the problems that the first sealing door 2 falls off or the connection part deforms due to the self - weight of the first sealing door 2, effectively reducing the maintenance cost. Moreover, a second sealing door is arranged on the first sealing door, and the corresponding sealing door can be opened according to the use requirements, which is convenient to use and has strong practicability.
[0035] Among them, it should be supplemented that, in order to facilitate the opening and closing of the first sealing door 2, a first handle 203 is arranged on the first sealing door 2. Preferably, the first handle 203 is arranged in a U - shaped manner.
[0036] Furthermore, the fixing member includes a first locking member 4 installed on the furnace body 1 and a first locking groove 201 formed on the first sealing door 2 and corresponding to the first locking member 4. Among them, the first locking member 4 includes a mounting plate 401 fixed on the furnace body 1 and a screw rod 402 rotatably connected to the mounting plate 401; a nut 403 is threadedly connected to the screw rod 402.
[0037] When the first sealing door 2 rotates to be parallel to the end of the furnace body 1, that is, after the first sealing door 2 seals the feeding port 101, manually rotate the screw rod 402 so that the screw rod 402 rotates to a position perpendicular to the first sealing door 2. At this time, the screw rod 402 is placed in the first locking groove 201, and then rotate the nut 403 so that the nut 403 presses against the first sealing door 2, thereby realizing the position fixation of the first sealing door 2.
[0038] As another embodiment of the present invention, a slag discharge port 202 is further formed on the first sealing door 2, and the slag discharge port 202 is blocked by a second sealing door 5, and a second handle 501 is arranged on the second sealing door 5.
[0039] Exemplarily, in a specific implementation manner, a plurality of second locking grooves 502 are formed on the second sealing door 5, and the second locking grooves 502 are engaged with a second locking member 7 installed on the first sealing door 2. Among them, the second locking grooves 502 have the same structure as the first locking grooves 201, and the second locking member 7 has the same structure and function as the first locking member 4. Therefore, this embodiment will not be elaborated herein.
[0040] In an embodiment, the second sealing door 5 needs to be used in cooperation with other mechanical equipment. For example, when the second sealing door 5 needs to be opened, other mechanical equipment is required to clamp and fix the second sealing door 5 to prevent the second sealing door 5 from falling due to its own weight.
[0041] Based on the above embodiment, the second sealing door 5 is also rotatably connected to the first sealing door 2 through a second rotating member 6, so as to ensure that when the second sealing door 5 is opened, there will be no problem of falling due to its own weight.
[0042] The first sealing door 2 and the second sealing door 5 described above can be set in a square or circular shape, etc. The specific shape can be selected according to actual needs, and this embodiment does not make specific limitations on this.
[0043] In this embodiment, the provided slag discharge port 202 is used to cooperate with the slag discharge elbow to realize the discharge of the waste residue in the furnace body 1 after cracking.
[0044] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
