DETAILED DESCRIPTION

[0035] 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.

[0036] 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.

[0037] 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.

[0038] The utility model aims to propose a structure of a furnace body for cracking or pyrolysis, mainly in that the structural features of the support rotation between the base and the furnace body are as follows:

[0039] See also Figures 1 to 6 In an embodiment of the utility model, a cracking furnace body comprises:

[0040] A base 1 and a furnace body 2 arranged on the base 1, wherein the outer wall of the furnace body 2 is provided with two drag rings 3 along its axial direction, and the two drag rings 3 are respectively abutted against a first drag wheel 4 and a second drag wheel 9 rotatably mounted on the base 1, wherein:

[0041] Both ends of the second tugboat 9 are formed with limiting protrusions 901 arranged in an annular structure, and one of the tug rings 3 is placed between two of the limiting protrusions 901 .

[0042] In this embodiment, the length of the line contact between the outer ring of the drag ring 3 and the second drag wheel 9 is equal to the thickness of the drag ring 3, so that the contact area between the drag ring 3 and the second drag wheel 9 can be effectively increased, and the anti-slip effect can be effectively achieved with the function of the limiting protrusion 901. At the same time, the drag ring 3 and the second drag wheel 9 only have line contact parallel to the axial direction of the drag ring 3, which can effectively reduce wear.

[0043] In this embodiment, there is no limit piece at the outer ring of the first tug wheel 4 , and when the furnace body expands, contracts and lengthens due to heating, the tug ring 3 in contact with the first tug wheel 4 may be displaced relative to the axial direction of the first tug wheel 4 .

[0044] For another exemplary embodiment, please refer to Figure 4-Figure 7 The first tugboat 4 and the second tugboat 9 are both coaxially rotatably mounted with a support shaft 5, and the support shaft 5 is slidably mounted on a support seat 10 fixed to the base 1, and is connected to an adjusting member mounted on the support seat 10.

[0045] Wherein, the adjusting member comprises:

[0046] A fixing seat 15 fixed on the supporting seat 10, wherein a second bolt 16 abutting against the supporting shaft 5 is threadedly connected to the fixing seat 15;

[0047] It also includes a first bolt 13 that passes through a first strip groove 12 formed on the support shaft 5 and a second strip groove 14 formed on the support seat 10. A nut 11 is threadedly connected to the first bolt 13, and the nut 11 abuts against the support shaft 5 to press the support shaft 5 against the support seat 10.

[0048] It should be additionally explained that, in the present embodiment, two first tugboats 4 are symmetrically provided, and two second tugboats 9 are symmetrically provided, which are used to support the furnace body 1 without affecting the rotation of the furnace body 1 .

[0049] In this embodiment, when the second bolt 16 is rotated relative to the fixing seat 15, the support shaft 5 can be driven to move relative to each other, so as to change the relative distance between the two first tugwheels 4 and the relative distance between the two second tugwheels 9, thereby adjusting the support height of the furnace body 1 to ensure that the furnace body 1 can be suitable for different use environments. At the same time, the height of the furnace body 1 can be fine-tuned to ensure the concentricity of the gas outlet and the gas outlet and slag discharge pipe of the furnace body 1, and eliminate the phenomenon of friction loss of sealing materials between the gas outlet and the gas outlet and slag discharge pipe. At the same time, the first bolt 13 and the nut 11 can cooperate to fix the support shaft 5 and the support seat 10 to prevent the displacement of the first tugwheel 4 or the second tugwheel 9.

[0050] Alternatively, the support shaft 5 is slidably mounted on the base 1 and connected to an adjusting member mounted on the base 1. The adjusting member has the same structure as the adjusting member described above, so this embodiment will not describe it in detail.

[0051] When the support shaft 5 is slidably installed on the base 1, a cooling groove is formed on the base 1 at a position directly opposite to the first tugwheel 4 and the second tugwheel 9, and a coolant can be added into the cooling groove to achieve cooling treatment on the surface of the first tugwheel 4 and the second tugwheel 9.

[0052] For an exemplary embodiment, please refer to Figure 8 and 9 At least one embedded channel 501 is formed on the support shaft 5, and gaps for bearing installation are formed between the support shaft 5 and the first tugboat 4 and the second tugboat 9. The embedded channel 501 is connected to the gap. Preferably, the embedded channel 501 is arranged in an L shape.

[0053] Through the embedded channel 501, engine oil, lubricating oil, etc. can be added into the gap to ensure the smooth rotation of the first tugboat 4 and the second tugboat 9. Of course, when no addition is needed, the port of the embedded channel 501 can be blocked by using a drill thread or a grease nipple.

[0054] For another exemplary embodiment, please refer to Fig.10 and Fig.11 A gap for bearing installation is formed between the support shaft 5 and the first tugboat 4 and the second tugboat 9. The first tugboat 4 and the second tugboat 9 are respectively formed with a first oil injection channel 401 and a second oil injection channel 902 along their radial directions for injecting oil into the inner side of the bearing. The first oil injection channel 401 and the second oil injection channel 902 can be blocked with a drill thread or a grease nipple. The first oil injection channel 401 and the second oil injection channel 902 are also provided for adding engine oil, lubricating oil, etc. into the gap.

[0055] For another exemplary embodiment, please refer to Fig.12 A gap is formed between the support shaft 5 and the first tugboat 4 and the second tugboat 9. End covers 17 are provided at both ends of the first tugboat 4 and the second tugboat 9. At least one third oil injection channel 1701 is formed on the end cover 17, and its function is also to add engine oil, lubricating oil, etc. into the gap.

[0056] The above are three examples of implementation modes, which can be adaptively selected during implementation.

[0057] Furthermore, an extension plate 7 is fixed at one end of the furnace body 2, and a through groove is formed on the extension plate 7, and a slot seat 8 is fixed on the base 1. When the through groove on the extension plate 7 is opposite to the slot seat 8, they can be fixed by plugging with a bayonet 6.

[0058] After the cracking is completed, the furnace body 2 can be controlled to rotate so that the extension plate 7 rotates to the position of the socket 8 and is then fixed by the latch 6. At this time, the furnace body 2 will no longer rotate relative to the base 1, which can effectively eliminate the safety hazard caused by the sudden rotation of the furnace body 2.

[0059] 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.

[0060] 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.
