[0002] The novel dry process kiln is a relatively complex thermal equipment, and is a combined system involving multiple devices, multiple processes and multiple reactions, and many processes and parameters cannot be completely obtained from theoretical calculation, so it is necessary to comprehensively analyze and evaluate the system through thermal calibration detection to realize the purposes of yield increase and stability, quality improvement and stability, cost reduction and benefit increase, energy saving and emission reduction.
[0003] The thermal calibration detection includes static pressure detection of high-temperature gas in the system. The gas static pressure detection is an important part of the whole thermal calibration process, and only when the gas static pressure is measured more accurately, conveniently and safely can the most real and accurate data support be provided for the thermal detection of the cement kiln.
[0004] The current gas static pressure detection mainly measures the pressure of high-temperature gas in the container through a detection hole, specifically, a sealing plug is arranged to seal the detection hole, a flow guide pipe is arranged in the sealing plug, the high-temperature gas in the container is guided out to the pressure gauge through the flow guide pipe, and the static pressure of the gas in the container is measured by the pressure gauge.
[0005] However, the relative position of the flow guide pipe and the detection hole cannot be guaranteed during the use of the sealing plug, for example, the flow guide pipe cannot be coaxially arranged with the detection hole, so that the inclined connection may disturb the airflow in the detection hole and result in inaccurate static pressure measurement. UTILITY MODEL CONTENTS
[0006] The utility model discloses a kind of sealing plugs for measuring gas static pressure and gas containers comprising it, the sealing plug for measuring gas static pressure and gas containers comprising it by flow guide pipe and sealing plug coaxial arrangement, and when installing, utilize alignment ring to guarantee that sealing plug and detection hole are in the position of relative coaxial, to guarantee the coaxial positional relationship of flow guide pipe and detection hole, and then guarantee the accuracy of gas static pressure measurement.
[0007] To achieve the above object, the utility model provides a kind of sealing plug for measuring gas static pressure, the sealing plug for measuring gas static pressure includes sealing plug and flow guide pipe, one end of the flow guide pipe is connected with measuring device for measuring the gas static pressure in the flow guide pipe;
[0008] The end of the flow guide pipe not connected with the measuring device passes through the sealing plug and contacts with the gas to be measured, and the sealing plug is coaxially arranged with the flow guide pipe;
[0009] An alignment ring is fixedly provided on the outer surface of the sealing plug, and the alignment ring protrudes from the outer surface of the sealing plug and is perpendicular to the axis of the sealing plug.
[0010] Preferably, the sealing plug is cone-shaped, comprising a soft outer layer on the outside and a rigid cone wrapped by the soft outer layer, the guide tube is embedded in the rigid cone and fixedly connected to the rigid cone, and the alignment ring is fixedly disposed on the outer surface of the soft outer layer.
[0011] Preferably, multiple alignment rings are provided, and the multiple alignment rings are evenly distributed along the height direction of the sealing plug.
[0012] Preferably, the spacing between two adjacent alignment rings is set to 10-20 mm.
[0013] Preferably, the alignment ring is set to a different color than the outer surface of the soft outer layer.
[0014] Preferably, the guide tube is provided with a heat-resistant handle, and the heat-resistant handle is fixedly connected to the guide tube.
[0015] Preferably, the anti-scalding handle is positioned close to the sealing plug.
[0016] Preferably, the sealing plug for measuring gas static pressure further includes a hose, and the guide tube is detachably connected to the hose.
[0017] This utility model also provides a gas container, which includes a container body, a detection hole, and a sealing plug for measuring gas static pressure that cooperates with the detection hole. The sealing plug is used to seal the detection hole. The guide tube is connected to the measuring device, and the measuring device measures the static pressure of the gas flowing out of the guide tube.
[0018] Preferably, the inner diameter of the detection hole is smaller than the maximum diameter of the rigid cone.
[0019] According to the above technical solution, this utility model uses a sealing plug to cooperate with the detection hole set in the container body, so that the guide tube can penetrate into the container body and export the gas in the container body to the measuring device, thereby achieving the purpose of measuring the static pressure of the gas in the container body.
[0020] By coaxially positioning the guide tube and the sealing plug, the guide tube can enter the container body parallel to the axis of the detection hole after the sealing plug is horizontally pushed into the detection hole. This avoids disturbing the gas in the detection hole after the guide tube enters the container body, thus ensuring the accuracy of the measurement results.
[0021] An alignment ring is fixedly provided on the outer surface of the sealing plug. By aligning the end of the detection hole with the alignment ring, the sealing plug and the detection hole can be made coaxial. Then, by uniformly controlling the pushing force on the sealing plug, the sealing plug can be pushed horizontally into the detection hole.
[0022] Preferably, multiple alignment rings are provided, and these rings are located on the outer surface of the soft outer layer. While pushing the sealing plug, the operator can determine whether the sealing plug is still coaxial with the detection hole based on the positional relationship between the alignment rings and the end of the detection hole. If the cross-section of the alignment ring is still parallel to the end face of the detection hole, then the sealing plug is considered to be coaxial with the detection hole. If the cross-section of the alignment ring is not parallel to the end face of the detection hole, then the sealing plug is considered to be no longer coaxial with the detection hole. In this case, the operator needs to adjust the direction of force to adjust the position of the sealing plug so that the sealing plug can always continue to penetrate into the detection hole along the direction coaxial with the detection hole, thereby reliably ensuring the relative position of the guide tube and the detection hole.
[0023] Therefore, by setting the guide tube and the sealing plug coaxially and using the alignment ring on the outer surface of the sealing plug, the relative position of the guide tube and the detection hole can be accurately controlled, thereby avoiding disturbance of the gas in the detection hole by the guide tube during the measurement process and ensuring the accuracy of the measurement results.

[0032] 5 Container body 22 First connector Detailed Implementation
[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0034] In this utility model, unless otherwise stated, directional words such as "one end," "the other end," "outer surface," "axis," "conical," and "near" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.
[0035] A sealing plug for measuring gas static pressure includes a sealing plug and a guide tube 2, one end of which is connected to a measuring device for measuring the gas static pressure inside the guide tube 2;
[0036] The end of the guide tube 2 that is not connected to the measuring equipment passes through the sealing plug and comes into contact with the gas to be measured. The guide tube 2 and the sealing plug are coaxially arranged.
[0037] An alignment ring 12 is fixedly provided on the outer surface of the sealing plug. The alignment ring 12 protrudes from the outer surface of the sealing plug and is perpendicular to the axis of the sealing plug.
[0038] By implementing the above technical solution, the sealing plug cooperates with the detection hole 4 provided in the container body 5, so that the guide pipe 2 can penetrate into the container body 5 and export the gas in the container body 5 to the measuring device, thereby achieving the purpose of measuring the static pressure of the gas in the container body 5.
[0039] The guide tube 2 is coaxially arranged with the sealing plug, so that after the sealing plug is pushed horizontally into the detection hole 4, the guide tube 2 can enter the container body 5 parallel to the axis of the detection hole 4. This avoids the guide tube 2 disturbing the gas in the detection hole 4 after entering the container body 5, thus ensuring the accuracy of the measurement results.
[0040] An alignment ring 12 is fixedly provided on the outer surface of the sealing plug. By aligning the end of the detection hole 4 with the alignment ring 12, the sealing plug and the detection hole 4 can be made coaxial. Then, by uniformly controlling the pushing force on the sealing plug, the sealing plug can be pushed horizontally into the detection hole 4.
[0041] Preferably, multiple alignment rings 12 are provided, and the multiple alignment rings 12 are provided on the outer surface of the soft outer layer 13. When the operator pushes the sealing plug, he / she can judge whether the sealing plug is still coaxial with the detection hole 4 based on the positional relationship between the alignment ring 12 and the end of the detection hole 4. If the cross section of the alignment ring 12 is still parallel to the end face of the detection hole 4, then it is considered that the sealing plug and the detection hole 4 are still coaxial. If the cross section of the alignment ring 12 is not parallel to the end face of the detection hole 4, then it is considered that the sealing plug and the detection hole 4 are no longer coaxial. At this time, the operator needs to adjust the direction of force to adjust the position of the sealing plug so that the sealing plug can always continue to penetrate into the detection hole 4 along the direction coaxial with the detection hole 4, thereby reliably ensuring the relative position of the guide tube 2 and the detection hole 4.
[0042] Therefore, by setting the guide tube 2 and the sealing plug coaxially, and using the alignment ring 12 set on the outer surface of the sealing plug, the relative position of the guide tube 2 and the detection hole 4 can be accurately controlled, thereby avoiding the disturbance of the gas in the detection hole 4 by the guide tube 2 during the measurement process and ensuring the accuracy of the measurement results.
[0043] In this embodiment, preferably, the sealing plug is cone-shaped, and the sealing plug includes a soft outer layer 13 located on the outside and a rigid cone 14 wrapped by the soft outer layer 13. The guide tube 2 is embedded in the rigid cone 14 and fixedly connected to the rigid cone 14. The alignment ring 12 is fixedly disposed on the outer surface of the soft outer layer 13.
[0044] The sealing plug is made into a cone shape. The small end of the cone can be easily pushed into the detection hole 4. Then, by continuously pushing the sealing plug in, the gap between the sealing plug and the inner wall of the detection hole 4 can be continuously reduced. The soft outer layer 13 fills the gap. As the gap gradually becomes smaller, the soft outer layer 13 will continuously deform and achieve the sealing effect on the detection hole 4 while deforming.
[0045] The alignment ring 12 is fixedly disposed on the outer surface of the flexible outer layer 13 to assist the operator in determining the relative position between the sealing plug and the detection hole 4. In one embodiment, the alignment ring 12 is integrally formed with the flexible outer layer 13, and the alignment ring 12 is configured as a structure with a certain width protruding from the outer surface of the flexible outer layer 13. Through this alignment ring 12, not only can the relative position between the sealing plug and the detection hole 4 be determined, but the sealing effect of the detection hole 4 can also be achieved.
[0046] In this embodiment, preferably, multiple alignment rings 12 are provided, and the multiple alignment rings 12 are evenly distributed along the height direction of the sealing plug.
[0047] Multiple alignment rings 12 are evenly arranged along the height direction of the sealing plug. The multiple alignment rings 12 are set on the outer surface of the soft outer layer 13. When the operator pushes the sealing plug, he can observe the positional relationship between the alignment ring 12 closest to the end of the detection hole 4 and the end of the detection hole 4, so as to determine whether the sealing plug is still coaxial with the detection hole 4.
[0048] The end of the detection hole 4 is set perpendicular to the axis of the detection hole 4.
[0049] If the cross section of the alignment ring 12 closest to the end of the detection hole 4 is parallel to the end face of the detection hole 4, then the sealing plug is considered to be coaxial with the detection hole 4. If the cross section of the alignment ring 12 is not parallel to the end face of the detection hole 4, then the sealing plug is considered to be no longer coaxial with the detection hole 4. In this case, the operator needs to adjust the direction of the applied force to adjust the position of the sealing plug so that the sealing plug can always penetrate deeper into the detection hole 4 along the direction coaxial with the detection hole 4, thereby reliably ensuring the reliability of the relative position of the guide tube 2 and the detection hole 4.
[0050] Preferably, when the gas temperature inside the container body 5 is high, the soft outer layer 13 is made of a high-temperature resistant material. This high-temperature resistant soft outer layer 13 can reliably protect the sealing plug, thereby improving the service life and operational reliability of the sealing plug.
[0051] Preferably, the soft outer layer 13 has a uniform thickness and material throughout, so that when the operator applies force along the axial direction of the detection hole 4 to push the sealing plug, the sealing plug can always enter the detection hole 4 along the axial direction of the detection hole 4.
[0052] In this embodiment, preferably, the spacing between two adjacent alignment rings 12 is set to 10-20 mm.
[0053] The smaller the distance between two adjacent alignment rings 12, the more reliably the operator can determine the relative position between the sealing plug and the detection hole 4 during use. However, this setting also leads to an increase in the number of alignment rings 12 on the outer surface of the soft outer layer 13, which not only increases the production cost of the soft outer layer 13 but also increases the difficulty of pushing in the sealing plug.
[0054] Preferably, the height of the alignment ring 12 is set to 2-3 mm, and the width is set to 3-5 mm. When the height of the alignment ring 12 is greater than 2 mm, the operator can distinguish between the outer surface of the soft outer layer 13 and the alignment ring 12. When the width of the alignment ring 12 is greater than 3 mm and the height is less than 3 mm, the alignment ring 12 has a certain strength, making it less prone to deformation or failure during use.
[0055] In this embodiment, preferably, the color of the alignment ring 12 and the outer surface of the soft outer layer 13 are set to be different.
[0056] By setting the color of the alignment ring 12 to be different from that of the outer surface of the soft outer layer 13, it is easier for the staff to compare the position of the end of the detection hole 4 with that of the alignment ring 12.
[0057] In this embodiment, preferably, the guide tube 2 is provided with a heat-resistant handle 21, and the heat-resistant handle 21 is fixedly connected to the guide tube 2.
[0058] When the gas temperature inside the container body 5 is high, after the sealing plug is pushed into the detection hole 4, the high-temperature gas will enter the guide tube 2. A heat-proof handle 21 is set on the guide tube 2, so that the staff can continuously insert the sealing plug through the heat-proof handle 21 to ensure the reliability of the seal between the sealing plug and the detection hole 4.
[0059] Before inserting the sealing plug, the guide tube 2 needs to be connected to the measuring equipment to prevent the high-temperature gas in the guide tube 2 from leaking.
[0060] In this embodiment, preferably, the anti-scalding handle 21 is located near the sealing plug.
[0061] Placing the anti-scalding handle 21 close to the sealing plug makes it easier for staff to apply force when installing the sealing plug, and helps staff to effectively push the sealing plug into the test hole 4.
[0062] In this embodiment, preferably, the sealing plug for measuring gas static pressure also includes a hose 3, and the guide tube 2 is detachably connected to the hose 3.
[0063] The flexible hose 3 is provided to connect the guide tube 2 and the measuring device, which facilitates the connection between the guide tube 2 and the measuring device.
[0064] Preferably, the hose 3 is used to connect the guide tube 2 by screwing. The end of the hose 3 is provided with a second connector 31, and one end of the guide tube 2 is provided with a first connector 22. The first connector 22 and the second connector 31 are provided with threads that can cooperate with each other. The connection between the hose 3 and the guide tube 2 can be achieved by screwing the first connector 22 and the second connector 31.
[0065] Similarly, the second connector 31 also enables a detachable connection between the hose 3 and the measuring device.
[0066] Preferably, the measuring device is a pressure gauge. After the hose 3 is connected to the pressure gauge, the gas pressure inside the container body 5 can be detected by pressing the sealing plug into the detection hole 4.
[0067] See Figure 1The container for measuring the static pressure of internal gas includes a container body 5, a detection hole 4, and a sealing plug that cooperates with the detection hole 4 for measuring the static pressure of the gas. The sealing plug is used to seal the detection hole 4. A guide tube 2 is connected to a measuring device, and the measuring device measures the static pressure of the gas flowing out of the guide tube 2.
[0068] By fitting the sealing plug with the detection hole 4, the measuring device can detect the gas pressure inside the container body 5 through the guide tube 2.
[0069] In this implementation method, preferably, the inner diameter of the detection hole 4 is smaller than the maximum diameter of the rigid cone 14.
[0070] The inner diameter of the detection hole 4 is smaller than the maximum diameter of the rigid cone 14. This is to prevent the sealing plug from being fully pushed into the detection hole 4 when it is being pushed, which would prevent a reliable seal from being achieved.

However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0072] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction.
