Anti-static pipe assembly for chemical supply systems

The present invention relates to a pipeline assembly, and more particularly to an innovative structural type of a pipeline assembly for reducing static electricity and metal ions for a chemical supply system.

According to the processing needs of many high-tech factories, a large amount of organic solvent supply and delivery pipelines are usually provided.

During the actual use of the organic solvent supply and delivery pipeline, when the organic solvent flows in the pipeline, a large amount of static electricity is generated due to the friction tube wall. When the static electricity accumulates too much, it may cause breakdown, flashover, spark, Accidents that cause significant risk hazards, such as ignition and explosion.

Another problem is that if the organic solvent supply and delivery pipeline is made of a metal material, there is usually a problem that metal ions in the structure may contaminate the pipeline, which may cause adverse effects of chemical changes in the organic solvent in the pipeline.

As shown in FIG. 5, the carbon layer 20B may also be bonded to the inner wall 11 of the Teflon tube 10 and the outer wall 12 in an inner sandwich type.

As shown in the first and second figures, the outer wall of the Teflon tube 10 can be covered with a conductive anti-slip pad 50 (which can be aluminum foil paper, tin foil paper, etc.). In this example, the arrangement of the conductive anti-slip pad 50 mainly enables the mounting position of the conductive band 30 to obtain better stability, so that it does not cause any sliding displacement and affects the smoothness of the extended state of the grounding wire 40.

With the above structural composition and technical features, the use case of the preferred embodiment of the present creative structure (ie, as shown in FIGS. 1 to 4) is as follows: the assembly of the components of the static reduction pipeline assembly A is relatively simple. First, please refer to Figure 1, the Teflon tube 10 can be configured according to the delivery route requirements of the chemical supply system. This part can be seen in Figure 6, which is Teflon tube 10 The configuration type disposed in the interior of the one-point valve box in the chemical supply system; then, the application personnel can perform the specific interval (for example, 1 meter, 3 meters, etc.) of the Teflon tube 10 The bundle of conductive straps 30 is set, and finally the grounding conductors 40 are passed through the conductor through holes 33 provided in the respective conductive straps 30 (note: the sheathing method has the advantages of simple and rapid positioning), and the grounding is performed. The grounding end 41 of the wire 40 is grounded, so that the assembly of the static reducing pipeline assembly A can be completed; as for the operation of the static reducing pipeline assembly A to reduce static electricity, mainly when the inside of the Teflon tube 10 is rubbed by the organic solvent The static electricity generated by the pipe wall will be first transmitted to the Teflon tube 10 The carbon layer 20 is then further conducted to the conductive strip 30, and finally the static conductive ground is discharged through the grounding wire 40, thereby achieving the purpose of reducing static electricity; on the other hand, the Teflon tube 10 itself disclosed in the present invention It has many advantages, because Teflon has a strong fluorocarbon bond and high molecular weight, which makes it have a variety of excellent properties, including a wide temperature range (-200 °C ~ +250 °C), for a variety of corrosive chemical liquids Such as strong acid, strong fluoric acid, strong alkali resistance, anti-stick properties, very low friction coefficient, flame resistance, excellent electrical properties (does not change with frequency and temperature changes), and applied to the chemical supply system demanded by this creation When using the pipeline structure, it mainly uses the excellent characteristics of reducing metal ions to solve the problem of pipe contamination, so that the organic solvent flowing in the pipeline does not cause chemical changes (ie, deterioration) due to the influence of metal ions.
