Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to a Claus furnace opening support device. Background Technology

[0002] In order to introduce the waste gas from the liquid sulfur pool into the Claus furnace for further conversion and recovery, it is necessary to drill holes in the Claus furnace and install pipes. Due to the aging of the Claus furnace itself and the vibration generated by the equipment during the drilling process, there is a risk of collapse before the hole wall is reinforced.

[0003] Therefore, a technical solution is needed to address the risk of collapse at the opening location of the Claus furnace due to the aging of the furnace itself and the vibration generated during the opening process. Utility Model Content

[0004] The purpose of this invention is to overcome the technical problem that the opening position of the Claus furnace is at risk of collapse due to the aging of the Claus furnace itself and the vibration generated by the equipment during the opening process, and to provide a Claus furnace opening support device.

[0005] This utility model provides a Claus furnace opening support device, including at least one lead screw mechanism. The lead screw mechanism includes a support rod, and each end of the support rod is provided with a pad. The pad is provided with a mounting hole adapted to the support rod. The pad is sleeved on the end of the support rod through the mounting hole. Each end of the support rod is threaded with a clamping nut. The clamping nut is located on the side of the pad facing the support rod.

[0006] This utility model discloses a Claus furnace opening support device. In use, the screw mechanism is placed inside the hole, with the pads at both ends of the support rod facing the hole wall. The clamping nut at the end of the support rod is rotated, and the clamping nut pushes the pads against the hole wall and presses them against the hole wall, thereby supporting the hole wall and reducing the risk of the hole wall collapsing before reinforcement.

[0007] Preferably, the clamping nut has a side hole on its side.

[0008] When in use, a rod can be inserted into the side hole to rotate the clamping nut, making it easier to rotate the clamping nut.

[0009] Preferably, the side of the pad away from the clamping nut is arc-shaped.

[0010] The side of the pad that abuts against the wall of the Claus furnace hole is designed in an arc shape, which can increase the contact area between the pad and the hole wall and provide more stable support for the hole wall.

[0011] Preferably, the pad is a wooden structural component.

[0012] Made of wood, it can support the hole wall. Its low hardness will not cause significant damage to the hole wall during the support process. Moreover, it can deform under the pressure of the hole wall during the support process, so that the pad fits more tightly with the hole wall and the support is more stable.

[0013] Preferably, the support rod includes a main rod, with threaded holes at both ends of the main rod, each threaded hole being equipped with a lead screw, and the pad being disposed on the lead screw.

[0014] The lead screw rotates in the threaded hole at the end of the main rod, which can change the total length of the support rod, thereby enabling the support rod to adapt to hole wall support with a larger range of hole diameters.

[0015] Preferably, there are two lead screw mechanisms, and the support rods of the two lead screw mechanisms are arranged crosswise.

[0016] By using two intersecting screw mechanisms to simultaneously support the borehole wall, the support range can be increased, reducing the risk of the Claus furnace collapsing.

[0017] Preferably, the two support rods are hinged at their intersection by a limiting pin.

[0018] The two support rods can rotate relative to each other, thereby changing the support position and support range. During the reinforcement operation, different support areas can be switched as the reinforcement position changes.

[0019] Preferably, the limiting pin has limiting nuts at both ends, and the two support rods are disposed between the two limiting nuts.

[0020] To prevent the lead screw mechanism from slipping off the limit pin during use.

[0021] Preferably, one of the support rods has a through groove in the middle, and the other support rod has a connecting block in the middle. The connecting block is embedded in the through groove, and the limiting pin passes through the through groove and the connecting block.

[0022] By setting a through groove in the middle of one support rod and a corresponding connecting block in the middle of the other support rod, one support rod can pass through the other support rod, avoiding misalignment between the two support rods. This allows the two screw mechanisms to support the same cross-sectional area of ​​the hole wall, making the support more precise and reducing the risk of collapse.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. This utility model provides a Claus furnace opening support device. By setting a screw mechanism, it can be directly inserted into the hole during use. The clamping nuts at both ends of the screw mechanism drive the pad to press against the hole wall, forming temporary support for the hole wall and reducing the risk of hole wall collapse.

[0025] 2. This utility model provides a Claus furnace opening support device, which has a simple structure, is easy to install and disassemble, can adapt to the support of hole walls with different hole diameters, and can be reused. Attached Figure Description

[0039] Example 1

[0040] like Figure 1 and Figure 2 As shown, a Claus furnace opening support device includes at least one lead screw mechanism 1. The lead screw mechanism 1 includes a support rod 11. Each end of the support rod 11 is provided with a pad 12. Each pad 12 is provided with a mounting hole 121 adapted to the support rod 11. The pad 12 is sleeved on the end of the support rod 11 through the mounting hole 121. Each end of the support rod 11 is threaded with a clamping nut 13. The clamping nut 13 is located on the side of the pad 12 facing the support rod 11.

[0041] When in use, place the lead screw mechanism 1 into the hole, with the pads 12 at both ends of the support rod 11 facing the hole wall. Rotate the clamping nut 13 at the end of the support rod 11, and the clamping nut 13 will push the pads 12 against the hole wall and press them against the hole wall, thereby supporting the hole wall and reducing the risk of the hole wall collapsing before reinforcement.

[0042] Compression nut 13: The compression nut 13 has a side hole on its side, into which a rod can be inserted to rotate the compression nut 13, making the rotation of the compression nut 13 easier.

[0043] Spacer 12: Spacer 12 is a wooden structural component. The wooden material can support the hole wall. Its low hardness will not cause significant damage to the hole wall during the support process. Moreover, it can deform under the pressure of the hole wall during the support process, so that spacer 12 fits more tightly with the hole wall and provides more stable support. The side of spacer 12 away from the clamping nut 13 is set as an arc shape, which can increase the contact area between spacer 12 and the hole wall and provide more stable support for the hole wall.

[0044] Example 2

[0045] like Figure 1 and Figure 3 As shown, in this embodiment, the difference from embodiment 1 is that the support rod 11 includes a main rod 111, and the main rod 111 has threaded holes 1111 at both ends, each of the threaded holes 1111 is equipped with a lead screw 112, and the pad block 12 is disposed on the lead screw 112.

[0046] In this embodiment, the lead screw 112 rotates in the threaded hole 1111 at the end of the main rod 111, which can change the total length of the support rod 11, thereby enabling the support rod 11 to adapt to hole wall support with a larger range of hole diameters.

[0047] Example 3

[0048] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that there are two lead screw mechanisms 1, and the support rods 11 of the two lead screw mechanisms 1 are arranged crosswise.

[0049] In this embodiment, by using two intersecting screw mechanisms 1 to simultaneously support the borehole wall, the support range can be increased, reducing the risk of collapse of the Claus 4 furnace.

[0050] Furthermore, the two support rods 11 are hinged at their intersection by a limiting pin 2, allowing the two support rods 11 to rotate relative to each other, thereby changing the support position and support range. During the reinforcement operation, different support areas can be switched as the reinforcement position changes.

[0051] Furthermore, limit nuts 3 are provided at both ends of the limit pin 2, and the two support rods 11 are arranged between the two limit nuts 3 to prevent the screw mechanism 1 from slipping off the limit pin 2 during use.

[0052] Furthermore, one of the support rods 11 has a through groove 1112 in the middle, and the other support rod 11 has a connecting block 1113 in the middle. The connecting block 113 is embedded in the through groove 1113. The main rod 111 is divided into two parts. One end of the connecting block 1113 is welded to one section of the main rod 111, and the connecting block 1113 passes through the through groove 1112 and is welded to the other section of the main rod 111. The limiting pin 3 passes through the through groove 1113 and the connecting block 1113 to prevent the two support rods 11 from being misaligned. This allows the two lead screw mechanisms 1 to support the same cross-sectional area of ​​the hole wall, making the support more precise and reducing the risk of collapse.

[0053] 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.
