Description

Technical Field

[0001] This utility model relates to the field of temperature measuring device technology, and in particular to a novel temperature measuring element with an anti-vibration structure. Background Technology

[0002] During boiler operation, flue gas needs to be emitted. To meet emission standards, the temperature of the emitted flue gas must be monitored. Traditionally, the temperature sensing insert (with the temperature probe at its tip) is directly inserted into the emission pipe. However, direct insertion causes the flue gas to impact and vibrate the insert, easily damaging it. To avoid damage, a protective tube is inserted into the emission pipe, allowing only the probe to protrude. However, this method still suffers from the risk of flue gas impacting the probe, causing vibration and friction between the insert and the protective tube, potentially damaging the insert. Furthermore, the protective sleeve and insert are not tightly fitted; the protruding probe, affected by the flue gas, can collide and rub against the sleeve opening, affecting the measurement results. Additionally, the protective sleeve itself has poor sealing; flue gas containing particulate matter entering the sleeve can also collide and rub against the insert, causing damage.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a novel temperature measuring element with a vibration-damping structure to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is as follows: A novel temperature sensing element with an anti-vibration structure is provided, comprising: a temperature sensing insert, a birdcage-type protective sleeve fitted over the front-end temperature sensing probe of the temperature sensing insert, and a insert retainer ring fitted over the tube body of the temperature sensing insert; the birdcage-type protective sleeve is a birdcage-like structure with several supporting ribs arranged in an alternating pattern. Preferably, there are 2-10 supporting ribs. By fitting the insert retainer ring over the tube body of the temperature sensing insert, when the temperature sensing insert is inserted into the protective tube, the protective tube can be effectively separated from and fixed to the tube body of the temperature sensing insert, avoiding vibration between the protective tube and the tube body of the temperature sensing insert, as well as friction caused by vibration, thus reducing the probability of damage to the temperature sensing insert; using the birdcage-type protective sleeve to protect the front-end temperature sensing probe can effectively reduce the intensity of flue gas turbulence experienced by the front-end temperature sensing probe, thereby reducing vibration.

[0006] Furthermore, the birdcage-style protective sleeve is threadedly connected to the front-end temperature probe. The threaded connection facilitates disassembly and installation.

[0007] Furthermore, the retaining rings are evenly distributed on the tube body of the temperature measuring insert.

[0008] Furthermore, the distance between the front-end temperature probe and the inner wall of the birdcage-style protective sleeve is 5-20mm.

[0009] Furthermore, the novel temperature sensing element of the vibration-damping structure also includes a ceramic flow guide ring fitted on the retaining ring of the insert. The ceramic flow guide ring can increase the sealing between the protective tube and the temperature sensing insert, reduce the entry of particulate-laden flue gas into the interior of the protective tube, reduce the flow velocity of the flue gas, and convert the sliding friction with the protective tube into rolling friction, thereby reducing the coefficient of friction.

[0010] By adopting the above-mentioned solution, this utility model provides a novel temperature measuring element with an anti-vibration structure. By fitting a retaining ring onto the body of the temperature measuring insert, the protective tube can be effectively separated and fixed from the body of the temperature measuring insert when the temperature measuring insert is inserted into the protective tube, thus preventing vibration and friction between the protective tube and the body of the temperature measuring insert, and reducing the probability of damage to the temperature measuring insert. The use of a birdcage-type protective sleeve to protect the front-end temperature measuring probe can effectively reduce the intensity of flue gas turbulence on the front-end temperature measuring probe and reduce vibration. Furthermore, the ceramic flow guide ring can increase the sealing between the protective tube and the temperature measuring insert, reduce the entry of flue gas containing particulate matter into the interior of the protective tube, reduce the flow velocity of the flue gas, and convert the sliding friction with the protective tube into rolling friction, thereby reducing the coefficient of friction.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Please see Figures 1-3This embodiment provides a novel temperature sensing element with an anti-vibration structure, comprising: a temperature sensing insert 10, a birdcage-style protective sleeve 11 fitted onto the front-end temperature sensing probe 13 of the temperature sensing insert 10, and an insert retainer ring 12 fitted onto the tube body of the temperature sensing insert 10; the birdcage-style protective sleeve 11 is a birdcage-like structure with several supporting ribs 14 arranged in an alternating pattern. In this embodiment, there are eight supporting ribs 14. By fitting the insert retainer ring 12 onto the tube body of the temperature sensing insert 10, when the temperature sensing insert 10 is inserted into the protective tube, the protective tube can be effectively separated from and fixed to the tube body of the temperature sensing insert 10, avoiding vibration and friction caused by vibration between the protective tube and the tube body of the temperature sensing insert 10, and reducing the probability of damage to the temperature sensing insert 10; using the birdcage-style protective sleeve 11 to protect the front-end temperature sensing probe 13 can effectively reduce the intensity of flue gas turbulence experienced by the front-end temperature sensing probe 13, and reduce vibration.

[0016] In this embodiment, the birdcage-style protective sleeve 11 is threadedly connected to the front-end temperature probe 13. The threaded connection facilitates disassembly and installation.

[0017] In this embodiment, the retaining rings 12 are evenly arranged on the tube body of the temperature measuring retainer 10.

[0018] In this embodiment, the distance between the front-end temperature probe 13 and the inner wall of the birdcage-style protective sleeve 11 is 5-20mm.

[0019] In this embodiment, the novel temperature sensing element of the vibration-damping structure further includes a ceramic flow guide ring 15 fitted on the insert retainer ring 12. The ceramic flow guide ring 15 can increase the sealing between the protective tube and the temperature sensing insert 10, reduce the entry of particulate matter-laden flue gas into the protective tube, reduce the flow rate of the flue gas, and convert the sliding friction with the protective tube into rolling friction, thereby reducing the coefficient of friction.

[0020] In summary, this utility model provides a novel temperature sensing element with an anti-vibration structure. By fitting a retaining ring onto the body of the temperature sensing insert, the protective tube is effectively separated from and fixed when the temperature sensing insert is inserted into the protective tube, preventing vibration and friction between the two tubes and reducing the probability of damage to the temperature sensing insert. The use of a birdcage-style protective sleeve to protect the front-end temperature sensing probe effectively reduces the intensity of flue gas turbulence on the probe, thus reducing vibration. Furthermore, the ceramic guide ring increases the sealing between the protective tube and the temperature sensing insert, reducing the entry of particulate-laden flue gas into the protective tube, lowering the flue gas velocity, and converting sliding friction with the protective tube into rolling friction, thereby reducing the coefficient of friction.

[0021] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
