Description

Technical Field

[0001] The utility model relates to the technical field of chemical safety, in particular to a chemical pipeline safety cover which is convenient to install. Background Art

[0002] The main material of chemical pipelines is ultra-high molecular weight polyethylene. Ultra-high molecular weight polyethylene is a thermoplastic engineering plastic with an average molecular weight greater than 2 million, which is polymerized by ethylene and butadiene monomers under the action of a catalyst. Chemical pipelines refer to special chemical composite pipelines that have been processed by anti-corrosion technology. In chemical production, many chemical raw materials will produce toxic gases during preparation. For example, if the ore contains sulfur, there will be sulfur-containing gases during the extraction process. Usually, sulfur-containing gases are toxic gases (mainly hydrogen sulfide), and many toxic gases are easily soluble in water. This makes it difficult to separate toxic gases at the source. Only by transporting this part of the solution with toxic gases through pipelines, because the pipeline needs to be connected through multiple sections to form a complete transportation channel, it is easy to leak in the connecting part. Once leaked, toxic gases will accumulate around the connecting part, which can easily cause environmental pollution and affect the health of the staff.

[0003] The existing chemical pipeline connection needs to be installed with a protective cover, which uses many fastening bolts, is difficult to disassemble and assemble, and has no sealing performance. When toxic gas leaks from the connection, the gas diffuses and affects the environment, which has poor practicality. Utility Model Content

[0004] To this end, the utility model provides a chemical pipeline safety cover that is easy to install to solve the problem that a protective cover needs to be installed at the chemical pipeline connection. The installation of the protective cover uses many fastening bolts, which is difficult to disassemble and assemble, and has no sealing performance. After toxic gas leaks from the connection, the gas diffuses and affects the environment, resulting in poor practicality.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chemical pipeline safety cover that is easy to install, comprising a first protective cover and a second protective cover, a chemical pipeline body is arranged between the first protective cover and the second protective cover, a plurality of through grooves are arranged on one side of the first protective cover, two slots are arranged on one side of the second protective cover, and a fixing mechanism is arranged on one side of the second protective cover;

[0006] The fixing mechanism includes a knob, which is arranged on one side of the second protective cover. A threaded rod is fixedly provided on one side of the knob. The threaded rod passes through the second protective cover and is connected to the second protective cover connection through a bearing. The threads on both sides of the outside of the threaded rod have opposite rotation directions. Sliding clips are provided on both sides of the outside of the threaded rod through threaded sleeves. A sliding column is movably connected to one side of the sliding clip through a rotating shaft. The sliding clip passes through the through slot and is buckled with the first protective cover.

[0007] Preferably, a gas detector is provided on one side of the first protective cover.

[0008] Preferably, two first washers are fixedly provided inside the first protective cover, and two slots are provided on one side of the first washers; two second washers are fixedly provided on one side of the second protective cover, and two blocks are fixedly provided on one side of the second washers, and the blocks extend into the slots.

[0009] Preferably, a plurality of positioning holes are formed on one side of the first protective cover, and a plurality of positioning posts are fixedly formed on one side of the second protective cover, and the positioning posts extend into the interior of the positioning holes.

[0010] Preferably, two pads are fixedly provided on one side of the second protective cover, and two pad grooves are provided on one side of the first protective cover, and the pads are in contact with the pad grooves.

[0011] Preferably, a connecting pipe is fixedly provided on one side of the first protective cover, and a cap is connected to one side of the connecting pipe through threads.

[0012] Preferably, the sliding card is slidably connected to the slot.

[0013] Preferably, an inclined groove is provided on one side of the through groove.

[0014] Preferably, the first gasket and the second gasket are both in contact with the chemical pipeline body.

[0015] The utility model embodiment has the following advantages:

[0016] 1. The threaded rod rotates, and the threaded rod drives the two sliding pallets to move. The sliding column at the bottom of the sliding pallet slides along the inclined groove toward the surface of the first protective cover, so that the first protective cover and the second protective cover are in closer contact, and the first gasket and the second gasket are in closer contact with the chemical pipeline body. The gasket strip enhances the sealing of the contact surface between the first protective cover and the second protective cover. The first protective cover and the second protective cover are installed by buckling the sliding pallet with the first protective cover. The installation speed is fast, the installation efficiency is high, and the sealing is high, which can prevent the leakage of toxic gases from affecting the environment.

[0017] 2. The leakage of toxic gas is detected by gas detector. When maintaining the connection of chemical pipeline, first close the gas transmission, turn off the cap, connect it to the connecting pipe through the absorption equipment and suck out the leaked toxic gas, then remove the first protective cover and the second protective cover, which is convenient for maintenance of the chemical pipeline. It can be disassembled quickly and the practicality of the protective cover is improved. BRIEF DESCRIPTION OF THE DRAWINGS
