[0002] Chemical industry pipeline is the pipeline for conveying material in chemical production process, specifically, in the chemical production process, the material required by production equipment is conveyed to the reaction equipment such as reaction kettle and other equipment through chemical industry pipeline.

[0003] Chemical industry pipeline is easy to corrode and then the penetration of material occurs in the process of using, especially in the process of conveying corrosive material frequently.And chemical material is mostly acid, alkali and flammable, explosive and other materials.Therefore, once the pipeline penetrates, the pipeline needs to be repaired in time, such as resealing the penetration position of the pipeline by welding.

[0004] And the repaired pipeline needs to be pressure tested to ensure that the pipeline can maintain safe conveying in the process of conveying material under certain pressure.The current test method is to pump material under certain pressure into the pipeline and keep a certain test time.However, in the actual test process, since the pipeline itself is repaired, once the sealing of the repair is not high, when the pressure rises to a certain size, the pipeline is easy to burst at the repair site (such as welding site), that is, the pipeline is not pressure-resistant and bursts, and the fragments produced by the burst have very high kinetic energy, under the high kinetic energy, the burst fragments of the pipeline are easy to cause very big safety accidents once they hit the working equipment or the operator.

[0044] Embodiment 1

[0045] As Figures 1-5As shown, a chemical pipeline detection explosion-proof device, including detection platform 4, the detection platform 4 is provided with pipeline pressure detection explosion-proof pipe mechanism. Through the pipeline pressure detection explosion-proof pipe mechanism realizes the installation on the detection pipeline 1 in the test process (the valve 11 on the detection pipeline 1 is kept closed during the test process), realizes the next first protection, that is, the detection pipeline 1 is not pressure resistant and the explosion pipe occurs, and the pipeline pressure detection explosion-proof pipe mechanism realizes the isolation of the test material fragments and the splash.

[0046] Specifically, the pipeline pressure detection explosion-proof pipe mechanism comprises clamping members arranged at intervals on the left and right sides, and the clamping members are clamped on the detection pipeline 1.

[0047] The specific structure of the clamping member is as follows:

[0048] The clamping member comprises an upper clamping plate 21 and a lower clamping plate 22 matched with the upper clamping plate 21; both have an arc-shaped clamping portion clamped on the test pipeline. The two ends of the arc-shaped clamping portion are integrally formed with protrusions, and the protrusions of the upper clamping plate 21 and the lower clamping plate 22 are slidably connected with a vertical screw rod 23, and the upper and lower ends of the vertical screw rod 23 are respectively threadedly connected with locking nuts locking the protrusions.

[0049] When the upper clamping plate 21 and the upper clamping plate 21 are clamped to the pipeline, the locking nuts are locked to realize the locking of the test pipeline.

[0050] At the same time, the arc-shaped clamping portion is fixedly connected with a ball member 25, and the ball member 25 comprises a ball seat 251, and a ball 252 is hingedly arranged in the ball seat 251 (the same as the existing hinged ball structure, a groove for limiting the ball is formed in the ball seat). The ball seat 251 is fastened in the arc-shaped clamping portion by connecting bolts and is arranged in an arc-shaped manner. When the upper clamping plate 21 and the lower clamping plate 22 are clamped to the detection pipeline 1, the ball is pressed against the detection pipeline 1.

[0051] The above-mentioned pipeline pressure detection explosion-proof pipe mechanism further comprises elastic corrugated baffles 3 arranged in front of and behind the detection pipeline 1; the elastic corrugated baffles 3 are made of elastic rubber material. The two ends are fixedly installed on the clamping member, and the specific way is that the upper and lower ends of the vertical screw rod are slidably connected with a protruding plate 32, and the vertical screw rod 23 is threadedly connected with a positioning nut for positioning the protruding plate 32; the upper and lower ends of the elastic corrugated baffles 3 on both sides are fastened to the positioning protruding plate 32 by long mounting screws 33. The detachable installation is realized by this way.

[0052] During testing, if a pipe ruptures, the flying pipe fragments, including welding slag, and other flying test materials will impact the resilient corrugated baffle 3. The curved structure of the resilient corrugated baffle 3 provides significant stability. During impact, if the impact force is uneven, the resilient corrugated baffle 3, fixed to the clamping element, will flip along with the clamping element on the test pipe 1. Specifically, the clamping element and the pipe are in contact via a ball bearing 25, and the rolling motion of the ball bearing 25 achieves the flipping of the resilient corrugated baffle 3. This flipping action buffers and reduces the kinetic energy of the flying fragments and gushing test materials, such as test water, thus protecting the equipment, personnel, and the testing area.

[0053] Example 2

[0054] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 1, in order to further increase the buffering of high-energy splashed fragments and materials and reduce their kinetic energy, a spring mesh structure 31 is fixedly connected between the upper and lower ends of the above-mentioned elastic corrugated baffle 3. Through the spring mesh structure 31, the fragments of the burst tube are damped, and the elastic corrugated baffles 3 on both sides are pulled.

[0055] When the elastic corrugated baffle 3 is impacted, it deforms. Under the elastic tension of the spring mesh structure, the elastic corrugated baffle 3 is protected from excessive deformation.

[0056] Specifically, the aforementioned spring mesh structure 31 includes several springs, with the two ends of each spring fixedly connected to the side walls of the elastic corrugated baffle 3 facing each other.

[0057] At the same time, the mesh structure formed by the spring mesh can also block and buffer splashes of pipe welding slag and pipe fragments.

[0058] Example 3

[0059] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 2, a support frame 2 is installed on the testing table 4 to support the testing pipe 1; during the testing process, the testing pipe 1 is supported on the support frame 2. Specifically, the support frame includes a collar seat that fits through the testing pipe, and a T-shaped bracket is fixedly connected to the bottom of the collar seat, and the T-shaped bracket is fixedly installed on the testing table 4.

[0060] Meanwhile, to complement the first line of protection formed by the aforementioned pipeline pressure testing and explosion-proof pipe mechanism, the aforementioned chemical pipeline testing explosion-proof device also includes an external baffle mechanism, with the pipeline pressure testing and explosion-proof pipe mechanism located within the external baffle mechanism. The external baffle mechanism provides a second line of protection, preventing all splashed debris from being randomly and at high speed. Specifically, the external baffle mechanism includes a baffle cylinder 52 that is pushed and pulled onto the testing platform 4. The baffle cylinder 52 is made of rubber.

[0061] The bottom of the blocking cylinder 52 is provided with a long sliding opening 521, and the T-shaped support slides on the long sliding opening 521 during the pushing and adjusting process of the blocking cylinder 52; the blocking cylinder 52 is slidably connected to the detection table 4 through the sliding support structure.

[0062] Specifically, the sliding support structure comprises long sliding rails 53 which are arranged at intervals in front and back, and the long sliding rails 53 are slidably connected to the blocking cylinder 52; the two sides of the long sliding rails 53 are respectively threadedly connected with nuts 531 which are positioned on the side walls of the blocking cylinder 52; the two ends of the long sliding rails 53 are respectively fixedly connected with vertical mounting frames 51 which are fastened to the side walls of the detection table 4 through connecting screws.

[0063] During the test, the sliding blocking cylinder 52 covers the pipe pressure detection explosion-proof pipe mechanism, and the blocking cylinder 52 keeps a certain distance from the pipe. When the blocking cylinder 52 covers the pipe, the nuts 531 on both sides are locked. Then the pipe is tested, and even if the pipe explodes, the fragments generated by the explosion will still be blocked in the cavity of the blocking cylinder 52 after breaking through the pipe pressure detection explosion-proof pipe mechanism under the double protection. The safety of the test work is further increased through the above-mentioned way.

[0064] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by the skilled in the art within the essential scope of the present application should also be within the protection scope of the present application.
