Description
Technical Field
[0001] This utility model relates to the field of chemical equipment technology, and in particular to a conical end cap for a chemical storage tank. Background Technology
[0002] End caps are a type of boiler component in pressure vessels. They are typically used at both ends of pressure vessels. They are also welded pipe fittings used to seal the ends of pipelines. There are many types. End caps are end covers on pressure vessels and are a major pressure-bearing component. Their function is to provide a seal.
[0003] When installing the end caps of chemical storage tanks, the end caps need to be positioned with the tank body and then welded using a welding torch.
[0004] The existing conical head device lacks external protection for the weld after welding, resulting in the weld being directly exposed to the outside. Over time, the weld is corroded, leading to poor sealing and affecting its use.
[0005] Therefore, it is necessary to provide a conical head for chemical storage tanks to solve the above-mentioned technical problems. Summary of the Invention
[0006] This utility model provides a conical end cap for a chemical storage tank, solving the problem of the lack of external protective devices for weld seams. To address the aforementioned technical problem, this utility model provides a conical end cap for a chemical storage tank, comprising a conical end cap, a reset assembly installed on the lower outer wall of the conical end cap, an annular plate connected to the reset assembly, an mounting plate fixedly installed on the top of the annular plate, a limit hole formed on the side wall of the mounting plate, and a locking assembly for limiting the position of the annular plate installed on the outer wall of the conical end cap, the locking assembly being connected to the limit hole.
[0007] Preferably, the upper outer wall of the conical end cap is provided with two sets of grooves, and a handle is fixedly installed on the inner wall of each set of grooves.
[0008] Preferably, the reset assembly includes a slide groove, and several sets of slide grooves are evenly opened on the lower outer wall of the conical head. A guide rod is evenly fixedly installed between the bottom and top of each set of slide grooves. A slider is slidably connected between the outer wall of each set of guide rods and the inner wall of the slide groove. The outer wall of each set of sliders is fixedly connected to the inner wall of the annular plate.
[0009] Preferably, a second spring is fixedly installed between the top of the slider and the top of the groove, and the second spring is sleeved on the outside of the guide rod.
[0010] Preferably, the locking assembly includes a mounting bracket, which is fixedly mounted on the upper outer wall of the conical end cap. A limit rod is inserted into the side wall of the mounting bracket, a handle is fixedly mounted on the outer wall of the limit rod, a limit plate is fixedly mounted on the inner side of the limit rod, and a spring is fixedly mounted between the limit plate and the mounting bracket.
[0011] Preferably, the conical head includes a head body, the outer wall of the head body is provided with a waterproof layer, and the inner wall of the head body is provided with an anti-corrosion layer.
[0012] Preferably, the bottom of the conical head is equipped with a sealing ring and several sets of positioning rods, and the positioning rods are inserted into the positioning holes at the top of the cylinder.
[0013] Compared with related technologies, the conical head for chemical storage tanks provided by this utility model has the following beneficial effects: When welding the conical head to the cylinder, pull the handle outward. The limiting rod will squeeze the spring through the limiting plate, and then push the annular plate upward. When the limiting hole on the mounting plate is aligned with the limiting rod, release the handle. The spring will automatically drive the limiting rod to insert into the limiting hole through the limiting plate, thereby locking the annular plate. After the conical head and the cylinder are welded, pull the limiting rod out of the limiting hole. The annular plate can slide down along the guide rod through the slider. The annular plate can seal the weld joint between the conical head and the cylinder to prevent the weld from being corroded. The combination of anti-corrosion and waterproof layers improves the corrosion resistance of the end cap body while preventing rainwater from seeping in, causing the end cap body to rust and reducing its service life.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] Please refer to the following: Figure 1 A schematic diagram of a preferred embodiment of a conical head for a chemical storage tank provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the positioning rod. Figure 3 for Figure 1 The diagram shows the structure of the conical head. Figure 4 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 5 for Figure 2 The enlarged schematic diagram of part B is shown. A conical end cap for a chemical storage tank includes: a conical end cap 1, a reset assembly 6 installed on the lower outer wall of the conical end cap 1, an annular plate 4 connected to the reset assembly 6, an mounting plate 7 fixedly installed on the top of the annular plate 4, a limit hole 8 formed on the side wall of the mounting plate 7, and a locking assembly 3 for limiting the position of the annular plate 4 installed on the outer wall of the conical end cap 1, the locking assembly 3 being connected to the limit hole 8.
[0018] The upper outer wall of the conical head 1 is evenly provided with two sets of grooves 9. The inner walls of the two sets of grooves 9 are fixedly installed with handles 2. When it is necessary to hoist the conical head 1, the hook of the hoisting equipment is connected to the handles 2, and the conical head 1 can be hoisted as a whole.
[0019] The reset assembly 6 includes a slide groove 61. Several sets of slide grooves 61 are evenly opened on the lower outer wall of the conical head 1. A guide rod 62 is evenly fixedly installed between the bottom and top of each set of slide grooves 61. A slider 64 is slidably connected between the outer wall of each set of guide rods 62 and the inner wall of the slide groove 61. The outer wall of each set of sliders 64 is fixedly connected to the inner wall of the annular plate 4.
[0020] After the conical head 1 is welded to the cylinder, the locking component 3 releases the limiting hole 8, and the annular plate 4 can slide down along the guide rod 62 via the slider 64. The annular plate 4 can seal the welded connection between the conical head 1 and the cylinder.
[0021] A second spring 63 is fixedly installed between the top of the slider 64 and the top of the inner groove 61, and the second spring 63 is sleeved on the outside of the guide rod 62.
[0022] When the locking component 3 releases its restriction on the limiting hole 8, the spring 63 will automatically push the slider 64 to move along the guide rod 62, thereby moving the annular plate 4 to the appropriate position.
[0023] The locking assembly 3 includes a mounting bracket 31, which is fixedly mounted on the upper outer wall of the conical head 1. A limit rod 32 is inserted into the side wall of the mounting bracket 31. A handle 35 is fixedly mounted on the outer wall of the limit rod 32. A limit plate 33 is fixedly mounted on the inner side of the limit rod 32. A spring 34 is fixedly mounted between the limit plate 33 and the mounting bracket 31.
[0024] When the conical end cap 1 needs to be welded to the cylinder, pull the handle 35 outward. The limiting rod 32 will squeeze the spring 34 through the limiting plate 33. Then push the annular plate 4 upward. When the limiting hole 8 on the mounting plate 7 is aligned with the limiting rod 32, release the handle 35. The spring 34 will automatically drive the limiting rod 32 to insert into the limiting hole 8 through the limiting plate 33, thereby locking the annular plate 4.
[0025] The conical head 1 includes a head body 12, the outer wall of which is provided with a waterproof layer 11, and the inner wall of which is provided with an anti-corrosion layer 13.
[0026] The combination of the anti-corrosion layer 13 and the waterproof layer 11 improves the corrosion resistance of the end cap body 12, while preventing rainwater from seeping in, causing the end cap body 12 to rust and reduce its service life.
[0027] The bottom of the conical head 1 is equipped with a sealing ring 10 and several sets of positioning rods 5. The positioning rods 5 are inserted into the positioning holes at the top of the cylinder. The positioning rods 5 are set to limit and stabilize the conical head 1 before welding. The sealing ring 10 is used to improve the sealing performance of the conical head 1.
[0028] The working principle of the conical head for a chemical storage tank provided by this utility model is as follows: After the conical end cap 1 is connected to the cylinder, the annular plate 4 is pushed upward to the locking component 3 by the reset component 6. Then, the locking component 3 limits the limiting hole 8 on the mounting plate 7, thereby ensuring that the annular plate 4 will not affect the welding operation during the welding process. After the welding is completed, the locking component 3 is released from the locking of the limiting hole 8, so that the annular plate 4 moves down to block the welding part and prevent the weld from being corroded.
[0029] Compared with related technologies, the conical head for chemical storage tanks provided by this utility model has the following beneficial effects: When the conical head 1 needs to be welded to the cylinder, pull the handle 35 outward. The limiting rod 32 will squeeze the spring 34 through the limiting plate 33. Then push the annular plate 4 upward. When the limiting hole 8 on the mounting plate 7 is aligned with the limiting rod 32, release the handle 35. The spring 34 will automatically drive the limiting rod 32 to insert into the limiting hole 8 through the limiting plate 33, thereby locking the annular plate 4. After the conical head 1 is welded to the cylinder, pull the limiting rod 32 out of the limiting hole 8. The annular plate 4 can slide down along the guide rod 62 through the slider 64. The annular plate 4 can seal the welded connection between the conical head 1 and the cylinder to prevent the weld from being corroded. The combination of the anti-corrosion layer 13 and the waterproof layer 11 improves the corrosion resistance of the end cap body 12, while preventing rainwater from seeping in, causing the end cap body 12 to rust and reduce its service life.
