Description

Technical Field

[0001] The utility model relates to the technical field related to cracking, in particular to a cracking furnace sealing device. Background Art

[0002] The cracking furnace insulation structure includes an insulation shell installed outside the furnace body and on the base. The inner side of the insulation shell is filled with insulation cotton to reduce heat loss in the furnace body. At the same time, insulation cotton is also filled between the end of the insulation shell and the outer wall of the furnace body.

[0003] Since the furnace body continuously rotates relative to the insulation shell during the cracking process, the insulation cotton is easily worn, resulting in a certain gap between the furnace body and the insulation shell, causing heat overflow. The existing process generally requires the machine to be shut down and then filled with insulation cotton, which is inconvenient to operate. Utility Model Content

[0027] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0028] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0029] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0030] See also Figures 1 to 3 In the embodiment of the utility model, a cracking furnace sealing device is provided with two groups, which are respectively installed at the two ends of the heat-insulating shell 1 and are sleeved on the outside of the furnace body 2, including:

[0031] The conical ring 3 is fixed to the end of the heat-insulating shell 1. In an exemplary embodiment, the conical ring 3 is integrally formed with the heat-insulating shell 1.

[0032] A plurality of baffles 4 are sequentially stacked along the circumferential direction of the conical ring 3 to form a fish-scale-like conical ring body, and one end of the baffle 4 is mounted on the conical ring 3;

[0033] Insulation cotton is filled between the baffle 4 and the furnace body 2. Preferably, the insulation cotton includes but is not limited to ceramic cotton, aluminum silicate cotton, etc.;

[0034] The binding rope structure 7 is sleeved on the outer sides of the multiple baffles 4 to generate a binding force on the multiple baffles 4 toward the center of the furnace body 2. Specifically, since the multiple baffles 4 form a conical ring body, when the binding rope structure 7 is tightened, there is an inclined pressure toward the baffles 4 to ensure the tightening effect of the multiple baffles 4.

[0035] Among them, a preferred embodiment is that the conical ring body is provided with two layers, the thermal insulation cotton is in a rectangular sheet structure, the thermal insulation cotton is filled between the two conical ring bodies, and the thermal insulation cotton exceeds the part of the two conical ring bodies, bypasses the conical ring body located in the inner layer and is bent and then pressed between the conical ring body and the furnace body 2.

[0036] In this embodiment, the baffles 4 are stacked in sequence and cooperated with the binding rope structure 7 to achieve closing adjustment. When the insulation cotton is worn during the rotation of the furnace body, the length of the binding rope structure 7 can be adjusted to achieve the insulation effect of the insulation shell 1, thereby reducing heat spillage and having strong practicality.

[0037] Furthermore, the overlapping parts of two adjacent baffles 4 are fixed to the conical ring 3 by means of a fixing member 5, wherein the fixing member 5 comprises: a stud fixed on the conical ring 3, the stud passing through a through hole formed on the baffle 4; a nut threadedly connected to the stud, the nut being pressed on the baffle 4. Specifically, two through holes are formed on each of the baffles 4. When two adjacent baffles are overlapped, one of the through holes on the two baffles 4 is coaxial and then mounted on the stud and then locked and fixed by the nut, which facilitates subsequent disassembly and replacement.

[0038] The baffle 4 is made of metal and is in a rectangular plate-shaped structure.

[0039] Furthermore, the cracking furnace sealing device also includes a plurality of hooks 6, which are equidistantly arranged along the circumference of the conical ring 3 and fixed on the baffle 4. Since the plurality of baffles 4 are stacked to form a conical ring structure, the hooks 6 can prevent the binding rope structure 7 from detaching from the baffle 4.

[0040] Exemplarily, in a specific embodiment, the binding rope structure 7 includes a binding rope 701 that is wrapped around multiple hooks 6, and both ends of the binding rope 701 are connected to an adjuster, and the adjuster is used to adjust the length of the binding rope 701, wherein the adjuster includes a frame-shaped member 704, and both ends of the frame-shaped member 704 are respectively threaded with bolts 703, and the end of the bolt 703 away from the frame-shaped member 704 is provided with a connecting hook 702 for connecting with the binding rope 701.

[0041] By rotating the frame 704, the two bolts 703 can be moved toward or away from each other, thereby achieving the tightening or loosening adjustment of the binding rope 701. Preferably, the binding rope 701 includes but is not limited to a steel wire rope.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0043] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
