Description

Technical Field

[0001] The present application relates to the technical field of acetylene cracking, and in particular to a limit ring structure for a connecting rod mechanism. Background Art

[0002] An acetylene cracking furnace is a core key equipment for producing acetylene by partial oxidation of natural gas. This cracking reaction is a rapid reaction under normal pressure and high temperature, and the main by-products of the reaction are carbon. These coke deposits adhere to the inner wall of the reaction chamber of the acetylene cracking furnace and need to be cleaned regularly.

[0003] Currently, during the operation of the carbon cleaning mechanism of the acetylene cracking furnace, due to the long connecting rod mechanism, large furnace diameter, and the free movement of the connecting rod mechanism inside the furnace body, the movement range of the connecting rod mechanism is large. When cleaning carbon, it is impossible to quickly and accurately locate the carbon cleaning position to clean the carbon deposits. At the same time, when the carbon cleaning operation is not carried out, the position and area where the connecting rod mechanism freely falls and topples are uncertain, and the time required to re-grasp the connecting rod mechanism during the next carbon cleaning operation is long, making it difficult to quickly enter the carbon cleaning operation.

[0004] Therefore, in order to solve the above problems, it is urgent to design a structure to improve the positioning efficiency of the connecting rod mechanism for carbon cleaning positions and at the same time improve the grasping efficiency of the connecting rod mechanism during multiple carbon cleaning operations. Utility Model Content

[0005] In order to improve the positioning efficiency of the connecting rod mechanism for carbon cleaning positions and at the same time improve the grasping efficiency of the connecting rod mechanism during multiple carbon cleaning operations, the present application provides a limit ring structure for a connecting rod mechanism.

[0006] The limit ring structure for a connecting rod mechanism provided by the present application adopts the following technical solutions:

[0007] A limit ring structure for a connecting rod mechanism includes a limit circular ring, the limit circular ring is arranged inside the furnace body through a support assembly, the limit circular ring is used to limit the movement of the connecting rod mechanism, and the connecting rod mechanism passes through the limit circular ring and cleans the inside of the furnace body.

[0008] By adopting the above technical solutions, the limit circular ring is arranged inside the furnace body through the support assembly, the connecting rod mechanism passes through the limit circular ring and carbon cleaning treatment is carried out on the inside of the furnace body; the movement range of the connecting rod mechanism is reduced by the limit circular ring, the positioning efficiency of the connecting rod mechanism for carbon cleaning positions is improved, and at the same time the limit circular ring limits the position where the connecting rod mechanism freely falls and topples, improving the grasping efficiency of the connecting rod mechanism during multiple carbon cleaning operations.

[0009] Further, the support assembly includes:

[0010] A support connection block, the support connection block is arranged on the inner side wall of the furnace body;

[0011] Support rod, one end of the support rod is arranged on the support connection block;

[0012] Ring connection block, the ring connection block is arranged on the limiting ring, and the ring connection block is connected to the end far from the support connection block.

[0013] By adopting the above technical solution, one end of the support rod is fixedly connected to the support connecting rod installed on the inner side wall of the furnace body, and the other end of the support rod is fixedly connected to the ring connection block installed on the limiting ring, so as to fix the limiting ring on the inner side wall of the furnace body.

[0014] Further, multiple groups of the support assemblies are provided, and the multiple groups of the support assemblies are arranged at intervals on the limiting ring and connected to the inner side wall of the furnace body, and the axis of the limiting ring coincides with the axis of the furnace body.

[0015] By adopting the above technical solution, the limiting ring is stably installed inside the furnace body through multiple groups of support assemblies. By making the axis of the limiting ring coincide with the axis of the furnace body, the cleaning effect of the connecting rod mechanism on the same height position inside the furnace body is the same.

[0016] Further, the support rod and the ring connection block are parallel to each other, the ring connection block is inclinedly arranged on the limiting ring, and the ring connection block is used to provide an inclined upward supporting force for the limiting ring.

[0017] By adopting the above technical solution, since the ring connection block and the support rod are parallel to each other, the probability of dislocation between the support rod and the ring connection block is reduced. At the same time, by the ring connection block providing an inclined upward supporting force for the limiting ring, the stability of the limiting ring inside the furnace body is improved.

[0018] Further, the included angle between the axis of the support rod and the axis of the limiting ring is 80 degrees.

[0019] By adopting the above technical solution, the shape and diameter of the limiting ring are manufactured according to the movement track of the connecting rod mechanism, and the included angle between the axis of the limiting ring and the axis of the support rod is determined by the diameter of the limiting ring and the length of the support rod.

[0020] Further, the contact surface between the limiting ring and the connecting rod mechanism is an arc structure.

[0021] By adopting the above technical solution, it is convenient for the connecting mechanism to move inside the limiting ring.

[0022] Further, the ring connection block and the support rod, the support connection block and the support rod are connected and locked by adopting multiple groups of locking parts, and the multiple groups of locking parts are offset from each other.

[0023] By adopting the above technical solution, multiple sets of locking members are connected in a staggered manner to improve the connection stability between the ring connection block and the support rod, and between the support connection block and the support rod.

[0024] Furthermore, the locking member includes a locking bolt and a locking nut. The locking bolt sequentially passes through the support connection block and the support rod and is locked tightly by the locking nut.

[0025] By adopting the above technical solution, the locking bolt sequentially passes through the support connection block and the support rod, and then the locking bolt is threadedly installed on the locking bolt. The locking bolt is screwed and pressed against the side wall of the support rod, thereby locking the support rod on the support connection block.

[0026] Furthermore, the support connection block is connected to the inner side wall of the furnace body by welding, and the ring connection block is connected to the limiting ring by welding.

[0027] By adopting the above technical solution, the support connection block is welded and installed on the side wall of the furnace body, and the ring connection block is welded and installed on the limiting ring, thereby improving the connection stability between the support connection block and the furnace body, and between the ring connection block and the limiting ring.

[0028] Furthermore, the inside of the limiting ring is hollow.

[0029] By adopting the above technical solution, the limiting ring limits the movement of the link mechanism. By designing the limiting ring as a hollow structure, while ensuring the strength of the limiting ring, the self-weight of the limiting ring is reduced, and thus the acting force of the limiting ring on the support assembly is reduced.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. By installing the support connection block on the inner side wall of the furnace body, the ring connection block on the outer side wall of the limiting ring, and locking and installing both ends of the support rod on the support connection block and the ring connection block respectively, the limiting ring is locked inside the furnace body. The link mechanism passes through the limiting ring and carbon cleaning is performed on the inside of the furnace body; the movement range of the link mechanism is reduced by the limiting ring, and the positioning efficiency of the link mechanism for carbon cleaning positions is improved.

[0032] 2. By limiting the position where the link mechanism freely falls and topples by the limiting ring, the grasping efficiency of the link mechanism during multiple carbon cleanings is improved.

[0033] 3. By designing the limiting ring into a hollow structure, while ensuring the strength of the limiting ring, the acting force of the limiting ring on the support assembly is reduced. Description of the Drawings

[0039] The following further elaborates on the present application in conjunction with the attached Figures 1-4 drawings.

[0040] The embodiments of the present application disclose a limit ring structure for a link mechanism.

[0041] Embodiment 1

[0042] Referring to Figure 1 , a limit ring structure for a link mechanism includes a limit ring 2. The limit ring 2 is arranged inside the furnace body 1 through a support assembly 3. The limit ring 2 is used to limit the movement of the link mechanism, and the link mechanism passes through the limit ring 2 to clean the inside of the furnace body 1.

[0043] Referring to Figure 1 , the furnace body 1 is a cylindrical structure, the limit ring 2 is a ring-shaped structure, the support assembly 3 is arranged on the inner side wall of the furnace body 1, and multiple groups of support assemblies 3 jointly support and fix the limit ring 2. Multiple groups of support assemblies 3 are arranged in a circumferential array on the outer side wall of the limit ring 2, so that the axis of the limit ring 2 coincides with the axis of the furnace body 1; at the same time, since the diameter of the limit ring 2 is smaller than the inner diameter of the furnace body 1, it is convenient for the limit ring 2 to limit the movement of the link mechanism. By making the axis of the limit ring 2 coincide with the axis of the furnace body 1, the cleaning effect of the link mechanism on the same height position inside the furnace body 1 is the same; in this embodiment, there are three groups of support assemblies 3, and the three groups of support assemblies 3 are installed in a circumferential array on the inner side wall of the furnace body 1 to support and fix the limit ring 2.

[0044] Referring to Figure 1 and Figure 2, the support component 3 includes a support connection block 31, a support rod 32, and a ring connection block 33. The support connection block 31 is fixedly installed on the inner side wall of the furnace body 1. One end of the support connection block 31 away from the inner side wall of the furnace body 1 is fixedly connected to the support rod 32 through a locking member 4. The locking member 4 includes a locking bolt 41 and a locking nut 42. The locking bolt 41 sequentially passes through the support connection block 31 and the support rod 32, and then the locking bolt 41 is threadedly installed on the locking bolt 41. By turning the locking bolt 41 and pressing it against the side wall of the support rod 32, the support rod 32 is locked on the support connection block 31. In order to improve the connection stability between the support connection block 31 and the support rod 32, the support connection block 31 and the support rod 32 are connected and locked through multiple groups of locking members 4. At the same time, in order to reduce the probability of rotation between the support connection block 31 and the support rod 32, the multiple groups of locking members 4 are offset from each other, so that the multiple groups of locking members 4 are in an asymmetric state. In order to improve the connection strength between the support connection block 31 and the inner side wall of the furnace body 1, the support connection block 31 and the furnace body 1 are connected by welding. In this embodiment, two groups of locking members 4 are provided between the support connection block 31 and the support rod 32.

[0045] Refer to Figure 1 and Figure 2 , the ring connection block 33 is fixedly connected to one end of the support rod 32 away from the support connection block 31. The connection method between the ring connection block 33 and the support rod 32 is the same as that between the support connection block 31 and the support rod 32, and both are connected and locked through multiple groups of offset locking members 4. One end of the ring connection block 33 away from the support rod 32 is fixedly connected to the outer side of the limiting ring 2. In order to improve the connection strength between the ring connection block 33 and the outer side wall of the limiting ring 2, the ring connection block 33 and the limiting ring 2 are connected by welding.

[0046] Refer to Figure 1 , in order to improve the support effect of the support component 3 on the limiting ring 2, the support rod 32 and the ring connection block 33 are parallel to each other. The ring connection block 33 is inclinedly installed on the limiting ring 2, so as to provide an inclined upward support force on the limiting ring 2. The limiting ring 2 is supported by multiple groups of ring connection blocks 33 together, so that the limiting ring 2 is stably installed on the inner side wall of the furnace body 1. In this embodiment, the included angle between the axis of the support rod 32 and the axis of the limiting ring 2 is 80 degrees, so as to facilitate the support and fixation of the limiting ring 2.

[0047] Refer to Figure 1In order to facilitate the movement of the connecting rod mechanism on the inner wall of the limiting ring 2, the contact surface between the limiting ring 2 and the connecting rod mechanism is an arc structure; the connecting rod mechanism passes through the limiting ring 2 and moves freely in the limiting ring 2. The limiting ring 2 reduces the movement range of the connecting rod mechanism, which is convenient for the connecting rod mechanism to quickly and accurately locate the carbon cleaning position to clean the carbon deposits during carbon cleaning; when carbon cleaning is completed, the limiting ring 2 limits the position where the connecting rod mechanism freely falls and tilts, so as to facilitate the quick grasping of the connecting rod mechanism during the next carbon cleaning.

[0048] The working principle of Example 1 of the present application is:

[0049] The support connection block 31 is installed on the inner wall of the furnace body 1, the ring connection block 33 is installed on the outer wall of the limiting ring 2, and the two ends of the support rod 32 are locked and installed on the support connection block 31 and the ring connection block 33 respectively, so as to lock the limiting ring 2 inside the furnace body 1, pass the connecting rod mechanism through the limiting ring 2 and clean the carbon inside the furnace body 1; the movement range of the connecting rod mechanism is reduced by the limiting ring 2, and the positioning efficiency of the connecting rod mechanism for the carbon cleaning position is improved. At the same time, the limiting ring 2 limits the position of the free fall and tilting of the connecting rod mechanism, which improves the grasping efficiency of the connecting rod mechanism during multiple carbon cleanings.

[0050] Example 2

[0051] Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that the limiting ring 2 is an internal hollow structure. By designing the limiting ring 2 as a hollow structure, the strength of the limiting ring 2 is ensured while the self-weight of the limiting ring 2 is reduced, thereby reducing the force of the limiting ring 2 on the supporting assembly 3.

[0052] The working principle of Example 2 of the present application is:

[0053] By designing the limiting ring 2 to be a hollow structure, the strength of the limiting ring 2 is ensured while the force exerted by the limiting ring 2 on the supporting assembly 3 is reduced.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
