Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a conical plug for organized waste gas sampling ports. Background Technology

[0002] Organized exhaust gas sampling is a crucial part of environmental monitoring and industrial process control. The structural design of the sampling port directly affects the sampling accuracy and system performance. Sampling ports typically use circular or rectangular cross-sections, but several problems exist in practical applications. Circular cross-sections are prone to particle deposition in exhaust gas, causing blockage of the sampling port. Secondly, rectangular cross-sections are prone to deformation in high-temperature or corrosive environments, affecting sampling accuracy.

[0003] When sampling organized exhaust gases, the sampling port needs to be blocked. Currently, cloth is often used to block it, but sometimes the block is not tight enough, causing air leakage at the sampling port and affecting the sampling data. Moreover, when using cloth to block, the sampling gun cannot be fixed, which may cause the sampling gun to tilt, resulting in unrepresentative samples. Furthermore, dust and particles can easily accumulate in the gaps, increasing the maintenance frequency and potentially leading to equipment failure or inaccurate sampling. Utility Model Content

[0004] The main purpose of this invention is to provide a conical plug for organized waste gas sampling ports, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An organized exhaust gas sampling port conical plug includes a sampling gun and a venting pipe. The sampling gun and the venting pipe are threaded together. A conical plug is fixedly connected to one side of the outer surface of the venting pipe. A limiter is fixedly connected to one side of the outer surface of the conical plug. The material of the conical plug is high-temperature silicone. The outer surface of the conical plug is coated with a titanium nitride coating.

[0007] To facilitate handling during operation, a handle is fixedly connected to one side of the outer surface of the conical plug at the organized exhaust gas sampling port of this utility model.

[0008] In order to enable the function of supporting rotation, as the conical plug of the organized exhaust gas sampling port of this utility model, a support is fixedly connected to one side of the outer surface of the vent pipe, and a rotating arm is rotatably connected to one side of the inner wall of the support.

[0009] To provide support for expansion and contraction, the conical plug for the organized exhaust gas sampling port of this utility model has a first spring on one side of its inner wall, a telescopic rod fixedly connected to one side of its outer surface, one end of the telescopic rod being fixedly connected to the vent pipe, and a second spring fixedly connected to one side of the outer surface of the telescopic rod.

[0010] To enable it to move, a rotating wheel is fixedly connected to one side of the outer surface of the rotating arm, which serves as the conical plug for the organized exhaust gas sampling port of this utility model.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this utility model, through the arrangement of a sampling gun, a vent pipe, a conical plug, a limiter, high-temperature silicone, and a titanium nitride coating, the user inserts the sampling gun into the sampling port. The shape of the conical plug effectively blocks the sampling port, preventing waste gas from escaping and increasing the accuracy of sample collection. At the same time, the limiter prevents the conical plug from shifting during use. The high-temperature silicone has excellent high-temperature resistance, maintaining its elasticity and sealing properties in high-temperature environments. Meanwhile, the titanium nitride coating has good resistance to various corrosive media, preventing chemicals in the waste gas from corroding the conical plug.

[0013] 2. In this utility model, by setting up a support, a rotating arm, a telescopic rod, and a rotating wheel, when in use, the user inserts the sampling gun into the sampling port. The telescopic rod supports the rotating arm, and the sampling gun enters the sampling port. The rotating wheel contacts the inner wall of the sampling port. Through the reaction force of the second spring, the telescopic rod extends and retracts, and the rotating arm rotates, so that the rotating wheel is in close contact with the inner wall of the sampling port. This achieves the effect of isolating the sampling gun from the inner wall of the sampling port when moving the sampling gun, preventing waste material from adhering to the inner wall and affecting the sampling results.

[0021] 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.

[0022] Example 1

[0023] like Figure 1-6 As shown, the organized exhaust gas sampling port conical plug includes a sampling gun 1 and a ventilation pipe 2. The sampling gun 1 and the ventilation pipe 2 are threaded together. A conical plug 3 is fixedly connected to one side of the outer surface of the ventilation pipe 2. A limiter 4 is fixedly connected to one side of the outer surface of the conical plug 3. The material of the conical plug 3 is high-temperature silicone 5.

[0024] In this embodiment, the outer surface of the conical plug 3 is coated with a titanium nitride coating 6.

[0025] In practical use, the user inserts the sampling gun 1 into the sampling port. The shape of the conical plug 3 effectively blocks the sampling port, preventing waste gas from flowing out and increasing the accuracy of sample collection. At the same time, the limiter 4 prevents the conical plug 3 from shifting during use. The high-temperature silicone 5 has excellent high-temperature resistance, maintaining its elasticity and sealing performance in high-temperature environments. Meanwhile, the titanium nitride coating 6 has good resistance to various corrosive media, preventing chemicals in the waste gas from corroding the conical plug 3.

[0026] In this embodiment, a handle 7 is fixedly connected to one side of the outer surface of the vent pipe 2.

[0027] In practical use, when moving and adjusting the ventilation tube 2, the fixedly connected handle 7 can effectively reduce the risk of slippage and ensure the safety of the operator.

[0028] In this embodiment, a support 8 is fixedly connected to one side of the outer surface of the vent pipe 2, and a rotating arm 9 is rotatably connected to one side of the inner wall of the support 8.

[0029] In practical use, the rotating arm 9 is supported by the support 8 so that the rotating arm 9 can rotate.

[0030] In this embodiment, a first spring is provided on one side of the inner wall of the support 8, and a telescopic rod 10 is fixedly connected to one side of the outer surface of the support 8. One end of the telescopic rod 10 is fixedly connected to the vent pipe 2, and a second spring is fixedly connected to one side of the outer surface of the telescopic rod 10.

[0031] In practical use, the rotating wheel 11 contacts the inner wall of the sampling port. Through the reaction force of the second spring, the telescopic rod 10 extends and retracts, so that the rotating wheel 11 is in close contact with the inner wall of the sampling port. This achieves the effect of isolating the sampling gun 1 from the inner wall of the sampling port when the sampling gun 1 is moved, thus preventing waste material from sticking to the inner wall and affecting the sampling results.

[0032] In this embodiment, a rotating wheel 11 is fixedly connected to one side of the outer surface of the rotating arm 9.

[0033] In practical use, the position and angle of the sampling port are automatically adjusted by the rotating arm 9, while the rotating wheel 11 provides the required driving force by rotating, so that the rotating arm 9 can run smoothly. The rotating wheel 11 has strong corrosion resistance to ensure reliable operation in complex industrial environments.

[0034] Working Principle: In use, the user inserts the sampling gun 1 into the sampling port. The conical plug 3 effectively blocks the sampling port, preventing waste gas from escaping and increasing the accuracy of sample collection. Simultaneously, the limiter 4 prevents the conical plug 3 from shifting during use. The high-temperature silicone 5 has excellent high-temperature resistance, maintaining its elasticity and sealing performance in high-temperature environments. The titanium nitride coating 6 provides good resistance to various corrosive media, preventing chemicals in the waste gas from eroding the conical plug 3. The telescopic rod 10 supports the rotating arm 9. When the sampling gun 1 enters the sampling port, the rotating wheel 11 contacts the inner wall of the sampling port. Through the reaction force of the second spring, the telescopic rod 10 extends and retracts, and the rotating arm 9 rotates, causing the rotating wheel 11 to press tightly against the inner wall of the sampling port. This ensures that when the sampling gun 1 is moved, it is isolated from the inner wall of the sampling port, preventing waste material from adhering to the inner wall and affecting the sampling results, thus completing the purpose of waste gas collection.
