Description

Technical Field

[0001] This utility model belongs to the field of pipeline assembly technology, specifically relating to an antistatic fluoropolymer-lined pipeline assembly device. Background Technology

[0002] Fluorine-lined pipes are widely used in the chemical, pharmaceutical, and food industries. Their inner walls or key components are lined with a layer of fluoroplastics (such as polytetrafluoroethylene, PTFE), which have excellent corrosion resistance, high temperature resistance and non-stick properties, making them an ideal choice for conveying highly corrosive media (such as nitric acid, sulfuric acid, hydrofluoric acid, etc.).

[0003] However, the current assembly and connection between two fluoropolymer-lined pipes usually only uses a single connection method of flange and bolt, which has low stability. Therefore, this application proposes an antistatic fluoropolymer-lined pipe assembly device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an antistatic fluoropolymer-lined pipe assembly device, which aims to solve the technical problem that the assembly and connection of fluoropolymer-lined pipes is not stable and firm enough under the existing technology.

[0005] Technical solution

[0006] To solve the above-mentioned technical problems, this utility model provides an antistatic fluoropolymer-lined pipe assembly device, including conductive collars fitted on the fluoropolymer-lined pipe body. A pair of conductive collars are provided, and the pair of conductive collars are respectively fixedly fitted at the connection of two fluoropolymer-lined pipe bodies. Each conductive collar has a conductive column vertically connected to its bottom, and the conductive column is erected on the ground. A tensioning member is provided between the pair of conductive collars, and the tensioning member applies a pulling force to the pair of conductive collars toward the opposite side.

[0007] Preferably, the conductive collar includes a first arc-shaped conductive buckle and a second arc-shaped conductive buckle. Both ends of the first and second arc-shaped conductive buckles are provided with lugs. A connecting bolt is connected between the two lugs located on the same side of the first and second arc-shaped conductive buckles. Through grooves are provided on the lugs located at both ends of the second arc-shaped conductive buckle.

[0008] Preferably, the first and second arc-shaped conductive clips are distributed vertically, and the conductive post is fixed to the bottom of the first arc-shaped conductive clip.

[0009] Preferably, the tensioning members are provided in two sets, and the two sets of tensioning members respectively tension a pair of second arc conductive fasteners and a pair of first arc conductive fasteners.

[0010] Preferably, the tensioning member includes a threaded sleeve and a screw threaded through both ends of the threaded sleeve. One end of the screw extending out of the threaded sleeve is connected to a first arc-shaped conductive fastener or a second arc-shaped conductive fastener. A hexagonal boss is provided at the middle position of the threaded sleeve.

[0011] Preferably, the first and second arc-shaped conductive fasteners are provided with a locking block on their outer circular surfaces. The locking block has a slot that can accommodate the screw. The end of the screw that extends out of the threaded sleeve is provided with a stop block.

[0012] Preferably, a retaining handle is fixedly fitted at one end of the screw that connects to the stop block. The retaining handle is configured as a flat structure and fits into the retaining groove.

[0013] Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes two sets of conductive collars. After two fluoropolymer-lined tubes are connected via flanges, two sets of first and second arc-shaped conductive fasteners are fitted onto the connection point of the two tubes. Connecting bolts are used to secure the first and second sets of conductive fasteners onto the fluoropolymer-lined tubes. The bottom of the conductive column is fixed to the ground. The conductive column and the first arc-shaped conductive fasteners work together to support the connection point of the fluoropolymer-lined tubes. Furthermore, the first arc-shaped conductive fasteners and the conductive column create a conductive path between the fluoropolymer-lined tubes and the ground, allowing static charges on the surface of the fluoropolymer-lined tubes to be quickly conducted to the ground, preventing static electricity accumulation and thus avoiding serious accidents such as fires or explosions caused by spark discharge due to static electricity accumulation.

[0016] By setting the tensioning component, the stop block is placed on one side away from each other of the two sets of conductive collars. The shank on the screw engages with the slot. Tightening the threaded sleeve rotates the screws, forcing the two screws to come together and applying tension to the two sets of first and second arc conductive fasteners. This can strengthen the connection between the two fluoropolymer-lined tubes. In addition, the conductive column and the first arc conductive fasteners support the connection between the two fluoropolymer-lined tubes, which greatly improves the stability of the assembly of the two fluoropolymer-lined tubes.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This embodiment provides an antistatic fluoropolymer-lined pipe assembly device, the structural schematic diagram of which is shown below. Figures 1-4As shown, the device includes a conductive collar 2 fitted onto a fluoropolymer-lined tube body 1. A pair of conductive collars 2 are provided, each fixedly fitted at the connection point of two fluoropolymer-lined tube bodies 1. Each conductive collar 2 has a vertically connected conductive post 3 at its bottom, which stands upright on the ground. Specifically, the conductive collar 2 includes a first arc-shaped conductive tab 5 and a second arc-shaped conductive tab 6. Both ends of the first and second arc-shaped conductive tabs 5 and 6 are provided with lugs 8. A connecting bolt 7 connects the two lugs 8 located on the same side of the first and second arc-shaped conductive tabs 5 and 6. Through grooves 9 are provided on the lugs 8 located at both ends of the second arc-shaped conductive tab 6, allowing the connecting bolt 7 to be inserted for easy connection with a nut. After the two fluoropolymer-lined pipe bodies 1 are connected by flanges, two sets of first arc-shaped conductive fasteners 5 and second arc-shaped conductive fasteners 6 are fitted onto the connection point of the two fluoropolymer-lined pipe bodies 1. The two sets of first arc-shaped conductive fasteners 5 and second arc-shaped conductive fasteners 6 are then fixed onto the fluoropolymer-lined pipe bodies 1 using connecting bolts 7. The bottom end of the conductive column 3 is fixed to the ground. At this time, the conductive column 3 and the first arc-shaped conductive fasteners 5 work together to support the connection point of the fluoropolymer-lined pipe bodies 1, improving the assembly strength of the two fluoropolymer-lined pipe bodies 1. The first arc-shaped conductive fasteners 5 and the conductive column 3 form a conductive path between the fluoropolymer-lined pipe body 1 and the ground, allowing the static charge on the surface of the fluoropolymer-lined pipe body 1 to be quickly conducted to the ground, avoiding the accumulation of static electricity. This can prevent serious accidents such as fires or explosions caused by spark discharge due to static electricity accumulation.

[0025] In this embodiment, the first arc-shaped conductive fastener 5 and the second arc-shaped conductive fastener 6 are distributed vertically, and the conductive post 3 is fixed at the bottom of the first arc-shaped conductive fastener 5. Thus, the conductive post 3 and the first arc-shaped conductive fastener 5 work together to better support the fluoropolymer-lined tube body 1.

[0026] In a further embodiment, a tensioning member 4 is provided between a pair of conductive collars 2. The tensioning member 4 applies a tension force to the pair of conductive collars 2 toward the opposite side. There are two sets of tensioning members 4, which respectively tighten a pair of second arc conductive fasteners 6 and a pair of first arc conductive fasteners 5. This structural design is used to reinforce the connection between the two fluoropolymer-lined tube bodies 1. Together with the conductive column 3 and the first arc conductive fasteners 5, the connection between the two fluoropolymer-lined tube bodies 1 is supported, thereby improving the stability of the assembly of the two fluoropolymer-lined tube bodies 1.

[0027] In this embodiment, the tensioning member 4 includes a threaded sleeve 12 and a screw 13 threaded through both ends of the threaded sleeve 12. One end of the screw 13 extending out of the threaded sleeve 12 is connected to the first arc-shaped conductive fastener 5 or the second arc-shaped conductive fastener 6. A hexagonal boss 16 is provided at the middle of the threaded sleeve 12. A locking block 10 is provided on the outer circumference of the first arc-shaped conductive fastener 5 and the second arc-shaped conductive fastener 6. The locking block 10 has a slot 11 that can accommodate the screw 13. A stop block 14 is provided at the end of the screw 13 extending out of the threaded sleeve 12. The end of the screw 13 connected to the stop block 14 is... The fixed set has a handle 15, which is designed as a flat structure and is fitted with a slot 11. The two screws 13 at both ends of the threaded sleeve 12 are inserted into the slots 11 on the block 10. The stop block 14 is placed on one side away from each other of the two sets of conductive collars 2. The handle 15 on the screw 13 is fitted with the slot 11 to restrict the rotation of the two screws 13. At this time, a wrench is used to rotate the threaded sleeve 12 with the help of the hexagonal boss 16, forcing the two screws 13 to come together and applying tension to the two sets of first arc conductive fasteners 5 and second arc conductive fasteners 6, thereby strengthening the connection of the two fluoropolymer-lined tube bodies 1.

[0028] Working principle: In use, after the two fluoropolymer-lined pipe bodies 1 are connected by flanges, two sets of first arc-shaped conductive fasteners 5 and second arc-shaped conductive fasteners 6 are fitted onto the connection point of the two fluoropolymer-lined pipe bodies 1. The two sets of first arc-shaped conductive fasteners 5 and second arc-shaped conductive fasteners 6 are fixed onto the fluoropolymer-lined pipe bodies 1 using connecting bolts 7. The bottom end of the conductive column 3 is fixed to the ground. At this time, the conductive column 3 and the first arc-shaped conductive fasteners 5 work together to support the connection point of the fluoropolymer-lined pipe bodies 1. The first arc-shaped conductive fasteners 5 and the conductive column 3 form a conductive path between the fluoropolymer-lined pipe body 1 and the ground, so that the static charge on the surface of the fluoropolymer-lined pipe body 1 can be quickly conducted to the ground, avoiding the accumulation of static electricity and preventing serious accidents such as fires or explosions caused by spark discharge due to static electricity accumulation. Furthermore, the two screws 13 at both ends of the threaded sleeve 12 are embedded into the slots 11 on the locking block 10. The stop block 14 is placed on one side away from each other of the two sets of conductive collars 2. The locking handle 15 on the screw 13 is engaged with the slot 11. Using a wrench, the threaded sleeve 12 is rotated by means of the hexagonal boss 16, forcing the two screws 13 to come together. This applies tension to the two sets of first arc conductive fasteners 5 and second arc conductive fasteners 6, thereby reinforcing the connection between the two fluoropolymer-lined tube bodies 1. In addition, the conductive column 3 and the first arc conductive fastener 5 provide support for the connection between the two fluoropolymer-lined tube bodies 1, which greatly improves the stability of the assembly of the two fluoropolymer-lined tube bodies 1.
