[0002] In industrial production, the dust removal system plays a vital role in production safety. For example, in the tobacco production process, a large amount of dust will be generated, which will not only seriously pollute the working environment, but also potentially cause major safety hazards such as fire. The dust removal system, with its efficient dust removal ability, can effectively remove dust in the workshop, thereby significantly reducing safety risks such as fire, and providing a solid guarantee for production safety. Therefore, the normal operation of the dust removal system is crucial. In order to ensure the stable operation of the dust removal system and timely discover potential problems, the national standard clearly stipulates that a pipeline inspection port should be set every 7 meters in the dust removal pipeline.
[0003] However, the current inspection port design of the dust removal pipeline has defects. Its design features a closed structure and a 90° vertical pipeline layout. This design greatly reduces the efficiency of maintenance and brings many inconveniences to daily maintenance and troubleshooting. This design makes it difficult for staff to observe the operating status of the dust removal pipeline in real time, and it is impossible to detect and deal with abnormal situations in time, thereby increasing safety risks. Therefore, it is necessary to optimize and improve the design of the dust removal pipeline inspection port to improve the convenience and efficiency of maintenance and ensure the normal operation and production safety of the dust removal system.

[0034] The present disclosure will be described below with reference to the accompanying drawings, wherein the accompanying drawings illustrate several embodiments of the present disclosure. However, it should be understood that the present disclosure can be presented in a variety of different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present disclosure more complete and fully illustrate the scope of protection of the present disclosure to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.
[0035] It should be understood that the same reference numerals represent the same elements throughout the drawings. In the drawings, the dimensions of certain features may be distorted for clarity.
[0036] It should be understood that the terms used in the specification are only used to describe specific embodiments and are not intended to limit the present disclosure. All terms (including technical terms and scientific terms) used in the specification have the meanings commonly understood by those skilled in the art unless otherwise defined. For the sake of simplicity and / or clarity, well-known functions or structures may not be described in detail.
[0037] As mentioned above, the inspection port of the dust removal duct is currently a closed structure and is arranged perpendicular to the duct. Therefore, maintenance personnel cannot see the inside of the duct through the inspection port without removing the panel of the inspection port. In addition, when a pipeline fails and needs to be repaired, it is necessary to use tools such as wrenches to remove the steel plate covering the inspection port in order to access the inside of the duct. Therefore, this design method greatly reduces the efficiency of maintenance and brings many inconveniences to daily maintenance and troubleshooting. This design makes it difficult for staff to observe the operating status of the dust removal duct in real time, and it is impossible to detect and deal with abnormal situations in time, thereby increasing safety risks. Therefore, it is necessary to optimize and improve the design of the inspection port of the dust removal duct to improve the convenience and efficiency of maintenance and ensure the normal operation and production safety of the dust removal system.

Figure 2 A front view of the pipeline 100 and the pipeline inspection port device 1 is shown, Figure 3 A top view of a pipeline 100 and a pipeline inspection port device 1 is shown. Figure 4 A left side view of the pipeline 100 and the pipeline inspection port device 1 is shown, Figure 5 Shown along Figure 2 A cross-sectional view of line AA in FIG. 1 , and Figure 6and 7 Shown is a view with the transparent panel removed.
[0039] like Figure 1-7 As shown, the pipeline inspection port device 1 according to the present application is arranged on a fixedly installed pipeline 100, and the pipeline inspection port device 1 comprises: a peripheral wall 11, the cross section of the peripheral wall is a closed shape, the space defined in the peripheral wall 11 is connected to the space inside the pipeline 100, the first end of the peripheral wall 11 is fixedly connected to the pipeline 100, and the second end of the peripheral wall 11 opposite to the first end defines an open opening 112; a transparent panel 12, which covers the opening 112 of the peripheral wall 11; and connecting members 13, 13', which are used to connect the transparent panel 12 to the peripheral wall 11. The peripheral wall 11, the opening 112 and the transparent panel 12 together define a linear observation path P (see Figure 4 , Figure 5 ), the angle α formed by the observation path P and the vertical direction V is a non-zero acute angle, and the maintenance personnel can observe the inside of the pipeline 100 through the observation path P. For example, the angle α formed by the observation path P and the vertical direction V is included in the range of 20°-70°, and preferably the angle α is 25°, 30° or 45°. The size of the angle α can be determined according to actual conditions (such as the size, installation position, installation height, etc. of the pipeline 100). The non-zero angle α not only optimizes the observation angle, but also enhances the clarity of observation, so that the maintenance personnel can see the operating status of the pipeline 100 more intuitively, greatly improving the efficiency of observation and maintenance.
[0040] Preferably, the second end of the peripheral wall 11 includes a flange 111, and the flange 111 extends outward along the periphery of the opening 112 of the peripheral wall 11. More preferably, a plurality of through holes 14 are formed on the flange 111, and the connecting member 13 passes through the through holes 14 and through corresponding through holes on the transparent panel, thereby connecting the transparent panel 12 to the flange 111 of the peripheral wall 11.
[0041] As shown in the embodiment, the cross section of the peripheral wall 11 is a rectangular shape, including four side walls. As known to those skilled in the art, the cross section of the peripheral wall 11 can be other closed shapes, such as a circle, a polygon, etc. The size and shape of the peripheral wall 11 are determined according to actual needs.
[0042] For example, the peripheral wall 11 is made of a metal material, and the pipe 100 is also made of a metal material, so the first end of the peripheral wall 11 can be connected to the pipe 100 in a welding manner.
[0043] Preferably, the pipeline inspection port device 1 further comprises a gasket 15, which is disposed between the second end (e.g., the flange 111) of the peripheral wall 11 and the transparent panel 12. More preferably, the gasket 15 is an elastic gasket, which is conducive to sealing the opening 112 of the peripheral wall 11.
[0044] Preferably, the transparent panel 12 is a plane panel, the observation path P is perpendicular to the plane of the transparent panel 12 and passes through the transparent panel 12, the opening 112 and the internal space of the peripheral wall 11, so that maintenance personnel can observe the interior of the pipeline 100 through the observation path P.
[0045] The transparent panel 12 can be made of transparent materials such as glass, resin, and plastic, so that maintenance personnel can directly observe the situation inside the pipeline 100 through the transparent panel 12. Preferably, the transparent panel 12 has characteristics suitable for the working conditions inside the pipeline 100, such as being suitable for harsh conditions such as high pressure and high temperature, for example, the transparent panel 12 is made of organic explosion-proof glass.
[0046] Preferably, the connecting member is a bolt 13 and a nut 13'. More preferably, the bolt 13 is a butterfly bolt as shown in the figure, and the nut 13' is a common hexagonal nut; or, the bolt is a common bolt (not shown), and the nut is a butterfly nut (not shown). The butterfly bolt or butterfly nut is easy to disassemble, and the maintenance personnel can manually disassemble or tighten the butterfly bolt or butterfly nut without using tools such as wrenches.
[0047] In practical applications, by using the pipeline inspection port device 1, when the pipeline 100 is in normal operation, the maintenance personnel can conveniently monitor the operation status of the pipeline 100 in real time by the transparent panel 12 beside the pipeline 100; when a fault occurs in the pipeline 100 and needs to be repaired, the maintenance personnel can manually remove the butterfly bolts or butterfly nuts without using tools, remove the transparent panel 12, and thus approach the inside of the pipeline 100. Therefore, the pipeline inspection port device 1 of the present application not only significantly improves the efficiency of maintenance work, but also reduces potential safety hazards to a great extent, ensuring the safety and stability of workshop production.
[0048] The pipeline inspection port device of the present application can monitor the operating status of the dust removal pipeline in real time and accurately by introducing an observation window and combining it with the inspection port. Whether it is dust accumulation, pipeline wear or other abnormal conditions, it can be clearly seen at a glance. This real-time monitoring capability improves observation and inspection efficiency, reduces maintenance costs, improves overall operating efficiency, and greatly reduces the major safety risks of tobacco dust explosion.
