Description

[0002] As a core piece of equipment in the ferroalloy production field, the submerged arc furnace widely uses carbon as a reducing agent to manufacture various ferroalloys by reducing ores. The bellows pressure ring, as one of its core components, controls the pressure inside the furnace based on the principle that the bellows expands and tightens during oil supply and contracts back into place during oil discharge. To ensure the stable operation of the bellows pressure ring under complex working conditions, especially in resisting external impacts, a protective device is usually added to its outer side.
[0003] In traditional design, such as Figure 1 As shown, a buffer seat structure is configured on the outer wall of the bellows pressure ring. Figure 1 (As shown in the dashed box) to enhance the impact resistance and cushioning performance of the outer wall of the bellows pressure ring. In practical applications, the shortcomings of the existing buffer seat design are that the buffer seat is welded to the outside of the pressure ring, which greatly limits the flexibility of the buffer seat installation and removal, thus causing inconvenience to the maintenance of the pressure ring and increasing the difficulty of replacing the buffer seat.
[0004] Therefore, how to optimize the design of the bellows pressure ring to improve the ease of installation and removal of the buffer seat, thereby facilitating the maintenance of the pressure ring and the replacement of the buffer seat, has become an urgent technical problem to be solved in the field of submerged arc furnace equipment design.

When the pressure ring body needs to be repaired or replaced, the snap-fit plates 111 located on both sides of the mounting block 110 are pushed inward to release the insertion relationship between the snap-fit plate 111 and the preset embedding position. Then, the entire buffer seat assembly 1 is pulled outward until the mounting block 110 is completely disengaged from the pressure ring body 2. The snap-fit plate 111 is then released to separate the buffer seat assembly 1 from the pressure ring body 2. Similarly, when installing the buffer seat assembly 1, the snap-fit plate 111 is pushed inward at the same time. After the snap-fit plate 111 enters the pressure ring body 2 and is aligned with the preset embedding position, the snap-fit plate 111 is released to snap the snap-fit plate 111 with the preset embedding position of the pressure ring body 2. Compared to the existing technology that welds the buffer seat to the pressure ring body, the detachable buffer seat assembly 1 used in this utility model improves the efficiency of disassembly and installation during pressure ring maintenance and facilitates the replacement of the buffer seat assembly.
[0020] Secondly, by providing a buffer plate 100 on the outside of the mounting plate 10, when the mounting plate 10 is subjected to an external force impact, the buffer plate 100 can use the buffer spring 102 to dissipate the impact force transmitted to the pressure ring body 2, thereby protecting the pressure ring body 2.

[0036] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0037] Example 1:
[0038] Embodiment 1 of this utility model provides a protective device for the pressure ring of the bellows in a submerged arc furnace, such as... Figure 2 As shown, it includes: multiple buffer seat assemblies 1 and a pressure ring body 2; the buffer seat assemblies 1 are arc-shaped, and the multiple buffer seat assemblies 1 are arranged around the pressure ring body 2. Figure 1 As shown in the example, in this embodiment, there are six buffer seat assemblies 1, evenly arranged around the pressure ring body 2. The buffer seat assembly 1 and the pressure ring body 2 are detachably connected.
[0039] like Figure 2 and Figure 3 As shown, the buffer seat assembly 1 includes a mounting plate 10 and multiple connecting units 11. The connecting units 11 are fixedly connected to the inner side of the mounting plate 10, and the connecting units 11 are detachably connected to the pressure ring body 2. A buffer pressure plate 100 is provided on the outer side of the mounting plate 10, and multiple buffer springs 102 are provided between the buffer pressure plate 100 and the mounting plate 10. Both ends of the buffer springs 102 are fixedly connected to the buffer pressure plate 100 and the mounting plate 10, respectively. A third receiving groove 101 is provided on the outer side of the mounting plate 10. The buffer pressure plate 100 is slidably connected to the third receiving groove 101. One end of the buffer spring 102 is fixedly connected to the buffer pressure plate 100, and the other end is fixedly connected to the bottom of the third receiving groove 101. To prevent the buffer springs 102 from rusting and breaking after long-term use, an anti-rust layer is provided on the outer side of the buffer springs 102.
[0040] In practical applications, when the buffer plate 100 is subjected to an external impact, the buffer plate 100 compresses the buffer spring 102 to dissipate the impact force transmitted to the pressure ring body 2, thereby protecting the pressure ring body 2.
[0041] Continue reading Figure 4The connecting unit 11 includes a mounting block 110 and a snap-fit plate 111. The mounting block 110 is fixedly disposed on the upper surface of the mounting plate 10. A first receiving groove 20 is provided on the outer surface of the pressure ring body 2, and the mounting block 110 is accommodated in the first receiving groove 20. The snap-fit plate 111 is disposed on both sides of the mounting block 110, and the snap-fit plate 111 is elastically connected to the mounting block 110. The snap-fit plate 111 is inserted into a preset embedding position of the pressure ring body 2. In this embodiment of the present invention, there are two snap-fit plates 111, respectively disposed on both sides of the mounting block 110.
[0042] In the first aspect, this utility model provides a mounting block 110 and a snap-fit plate 111 on the buffer seat assembly 1, and provides a corresponding insertion position on the pressure ring body 2. When it is necessary to inspect or replace the pressure ring body 2, it is pressed inward simultaneously (e.g., Figure 4 (As indicated by the arrows) The snap-fit plates 111 on both sides of the mounting block 110 are disengaged from their preset insertion positions, thereby releasing the snap-fit plates 111 from the pressure ring body 2. Then, the entire buffer seat assembly 1 is pulled outward until the mounting block 110 is completely disengaged from the pressure ring body 2. The snap-fit plates 111 are then released, separating the buffer seat assembly 1 from the pressure ring body 2. Similarly, when installing the buffer seat assembly 1, the snap-fit plates 111 are pressed inward until they enter the pressure ring body 2 and align with their preset insertion positions. Then, the snap-fit plates 111 are released, locking them into their preset insertion positions on the pressure ring body 2. Compared to the existing method of welding the buffer seat to the pressure ring body 2, the detachable buffer seat assembly 1 used in this invention improves the efficiency of disassembly and installation during pressure ring maintenance and facilitates the replacement of the buffer seat assembly 1. Secondly, by providing a buffer plate 100 on the outside of the mounting plate 10, when the mounting plate 10 is subjected to an external force impact, the buffer plate 100 can use the buffer spring 102 to dissipate the impact force transmitted to the pressure ring body 2, thereby protecting the pressure ring body 2.
[0043] To connect the pressure ring body 2 to the mounting block 110 and the snap-fit plate 111, the side wall of the first receiving groove 20 is provided with an insertion groove 200, and the side of the snap-fit plate 111 is provided with an insertion block 112. The insertion block 112 is inserted into the insertion groove 200 to fix the connecting unit 11 as a whole relative to the pressure ring body 2. In this embodiment of the present invention, there are two insertion grooves 200, corresponding to the insertion blocks 112 on the two snap-fit plates 111 respectively. The first receiving groove 20 extends from the outer side of the pressure ring body 2 to the inner side. To facilitate the installation and disassembly of the plug-in block 112 and the plug-in slot 200, a pre-set gap is provided between the side wall and bottom of the plug-in slot 200 and the plug-in block 112. The pre-set gap can be between 2mm and 4mm. Since the force on the buffer seat assembly is basically a radial force, and its direction is towards the center of the pressure ring body 2, there is basically no impact between the bottom of the plug-in slot 200 and the plug-in block 112. That is, in this embodiment, there is a certain amount of spare space between the plug-in block 112 and the plug-in slot 200, mainly for ease of installation. When subjected to impact force, although the plug-in block 112 will have a slight displacement relative to the plug-in slot 200, it will not affect the buffering effect.
[0044] The above solution mentions that the snap-fit plate 111 is elastically connected to the mounting block 110, see reference. Figure 5 Specifically, the mounting block 110 has a second receiving groove 113 on its side, and a connecting spring 114 is provided between the snap-fit plate 111 and the second receiving groove 113. One end of the connecting spring 114 is fixedly connected to the snap-fit plate 111, and the other end is fixedly connected to the bottom of the second receiving groove 113. In this embodiment of the present invention, there are two second receiving grooves 113, which correspond to the snap-fit plates 111 provided on both sides of the mounting block 110.
[0045] To facilitate pushing the snap-fit plate 111, a pressing push plate 115 is provided on the side of the snap-fit plate 111. The pressing push plate 115 and the insertion block 112 are located on the same side of the snap-fit plate 111. The pressing push plate 115 includes a connecting rod 120 that is fixedly connected to the body of the snap-fit plate 111.
[0046] In practical applications, when disassembling or installing a buffer seat assembly 1, all the pressing push plates 115 need to be pushed simultaneously to remove the buffer seat assembly 1 as a whole. Therefore, a mechanical clamp (not shown in the figure) is provided on the outside of the buffer seat assembly 1. The mechanical clamp can simultaneously clamp and push all the pressing push plates 115 located on both sides of the mounting block 110 to disassemble or install the buffer seat assembly 1 as a whole. The mechanical clamp can be implemented using existing technology and is not the main innovation of this utility model, so it will not be described in detail here. To facilitate the clamping of the pressing push plates 115 by the mechanical clamp, the surface of the pressing push plates 115 is provided with anti-slip protrusions 116. The anti-slip protrusions 116 can be in the form of a dot matrix or a strip array, etc.
[0047] During the process of the mechanical clamp pushing and pressing the push plate 115, the movement trajectory of the snap-fit plate 111 body may be disturbed by the thrust in a non-preset direction. In order to ensure that the movement trajectory of the snap-fit plate 111 remains straight, the outer side of the snap-fit plate 111 is provided with a guide protrusion 117, and the side wall of the second receiving groove 113 is provided with a guide slide groove 118. The guide protrusion 117 is slidably connected to the guide slide groove 118.
[0048] Because there is a certain amount of extra space between the plug-in block 112 and the plug-in slot 200, when the buffer plate 100 is impacted by an external force, the plug-in block 112 may collide with the side wall of the plug-in slot 200. After prolonged use, fatigue fracture may occur at the connection between the plug-in block 112 and the snap-fit plate 111. Therefore, a spring array 119 is provided between the mounting block 110 and the bottom of the first receiving slot 20. One end of the spring array 119 is fixedly connected to the mounting block 110, and the other end abuts against the bottom of the first receiving slot 20; or, one end of the spring array 119 is fixedly connected to the first receiving slot 20, and the other end abuts against the mounting block 110. When impacted, the spring array 119 applies a pushing force to the mounting block 110 to minimize the impact between the plug-in block 112 and the side wall of the plug-in slot 200, or to reduce the impact force between the plug-in block 112 and the side wall of the plug-in slot 200.
[0049] In summary, the installation and disassembly method of the protective device for the pressure ring of the corrugated pipe of the electric arc furnace provided in this embodiment of the present invention is as follows: During installation, the mechanical clamp simultaneously clamps the snap-fit plates 111 located on both sides of the mounting block 110 and pushes the buffer seat assembly 1 inward. When the plug-in block 112 begins to enter the first receiving groove 20 and abuts against the side wall of the first receiving groove 20, the mechanical clamp is released, and the plug-in block 112 slides along the side wall of the first receiving groove 20 until the plug-in block 112 is aligned with the opening of the plug-in groove 200. Under the push of the connecting spring 114, the snap-fit plate 111 bounces, and the plug-in block 112 snaps into the plug-in groove 200.
[0050] During use, when the outer side of the pressure ring body 2 is impacted by an object, the buffer plate 100 comes into contact with the object, causing it to move under force and squeeze the buffer spring 102. The buffer spring 102 buffers the impact force, which reduces the impact force on the pressure ring body 2 and provides good protection for the pressure ring body 2.
[0051] During disassembly, mechanical clamps can be used to clamp the snap-fit plates 111 on both sides of the mounting block 110, and the buffer seat assembly 1 can be pulled outward to remove the plug block 112 from the plug slot 200. Continue to move the buffer seat assembly 1 until the buffer seat assembly 1 is completely separated from the pressure ring body 2.
[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
