Description

Technical Field

[0001] This utility model relates to the field of artificial detection of voids in generators, specifically a blowout prevention mechanism for a flame detection hole in a generator. Background Technology

[0002] Manual empty layer detection in a gasifier refers to the process by which operators, using specific tools, manually measure the height of the space between the top surface of the material layer and the top of the furnace during the operation of a gasifier. Tools such as iron rods are typically used, which are manually inserted into the furnace. The depth of the insertion is used to determine the empty layer height. For example, in the actual operation of some gasifiers, workers may use an iron rod to detect the empty layer (measure the total layer height) every hour. During this operation, the cover of the detection hole must be opened first, and the operator must stand upwind to prevent gas poisoning. After the operation, the cover must be closed promptly. By detecting the empty layer height, the condition of the material layer inside the furnace can be understood, and this information can be used to rationally control the feeding and ash removal rates to ensure that the empty layer height is within an appropriate range.

[0003] For example, the Chinese authorized patent CN205133528U, entitled "A Water Seal Device for a Flame Detection Hole of a Gas Generator", has a handle connected above the cover plate, an intermediate cylinder connected below the cover plate, an inner cylinder and an outer cylinder connected above the bottom flange, and a gasket connected below the bottom flange. When the cover is placed into the base, the intermediate cylinder is located between the inner cylinder and the outer cylinder, providing a double-layer water seal for the gas leaking out due to wear on the sealing surface of the flame detection hole plug.

[0004] In the aforementioned prior art, when measuring the empty space length of the gas generator at a gas station, the tar inside the generator sprays out as the flame detection hole is opened, which not only contaminates the surrounding equipment but also easily burns the operators. Therefore, it does not meet the current requirements. In response, we propose a flame detection hole anti-spray mechanism for generators. Utility Model Content

[0005] The purpose of this invention is to provide a flame detection hole anti-spray mechanism for a producer, so as to solve the problem mentioned in the background art that internal tar is easily sprayed out during the measurement of the empty layer of the producer through the flame detection hole.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a blowout prevention mechanism for a flame detection hole in a producer furnace, comprising a producer furnace flame detection tube, wherein a blowout prevention mechanism is provided in the inner hole of the producer furnace flame detection tube, the blowout prevention mechanism comprising an inner convex ring, the inner convex ring being welded and fixed to the upper end of the inner hole of the producer furnace flame detection tube, a nut being installed at the center position of the upper end face of the inner convex ring, the edge of the lower end face of the nut being welded and fixed to the inner convex ring, and the axis of the nut being consistent with the center hole of the producer furnace flame detection tube, a closing plate for automatically closing the flame detection hole being symmetrically provided at the bottom of the blowout prevention mechanism, and a pressure relief mechanism being provided on one side of the upper end face of the inner convex ring for discharging the pressurized gas generated during the detection of the void layer in the producer furnace by the probe.

[0007] Preferably, the bottom of the inner convex ring is provided with a mounting groove, the closing plate is limited inside the mounting groove, and the closing plate and the mounting groove are connected by a rotating shaft. A torsion spring is installed on the outside of the rotating shaft, and the two ends of the torsion spring are fixed to the closing plate and the mounting groove respectively.

[0008] Preferably, the pressure relief mechanism includes a sleeve, the lower end of which is provided with a sealing port and the upper end of the sealing port is concave. A fixing plate is fixedly provided at the upper end of the sleeve. The fixing plate has multiple annularly distributed through holes inside. An elastic telescopic component is installed at the middle position of the bottom of the fixing plate. A piston is installed at the bottom of the elastic telescopic component and is adapted to the sealing port.

[0009] Preferably, the elastic telescopic component consists of a fixed tube, a movable rod, and a spring. The fixed tube is fixed to the bottom of the fixed plate, the movable rod slides with the fixed tube, and the bottom of the movable rod is fixed to the piston. The spring is installed outside the fixed tube and the movable rod.

[0010] Preferably, a pressure relief hole is provided on one side of the bottom of the inner convex ring, and the pressure relief hole is connected to the bottom of the sleeve, and an exhaust pipe connected to the inner cavity is provided at the front end of the sleeve.

[0011] Preferably, the upper end face of the generator fire probe is integrally formed with a flange connecting plate, and the flange connecting plate has annularly distributed connecting holes inside.

[0012] Preferably, the rotation angle of the closing plate is in the range of zero to ninety degrees.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model incorporates an anti-spray mechanism. By welding an inner convex ring onto the inner liner of the generator's flame detection tube, the nut to be installed can be easily supported. By aligning the nut's axis with the center hole of the generator's flame detection tube, the nut is welded and fixed to the upper end face of the inner convex ring. After welding, the center hole of the nut serves as the insertion port for the probe, and its diameter is slightly larger than the probe diameter by 0.5-1mm. This design significantly reduces the area of ​​tar and steam ejected when the generator's flame detection hole is opened to measure the empty layer, effectively reducing the degree of pollution to surrounding equipment and thus reducing the risk of burns to operators. This creates safer working conditions for operators and avoids injuries, shutdowns, and other situations caused by burns.

[0015] 2. This utility model installs closing plates on both sides of the bottom of the inner convex ring. These closing plates rotate with the inner convex ring via a rotating shaft, on which a torsion spring is mounted. When the closing plates are not under force, the elastic return of the torsion springs causes the two closing plates to seal the probe insertion hole. Simultaneously, the inner convex ring limits the closing plates, preventing them from moving upwards after sealing the probe insertion hole, ensuring the stability of the seal. When the probe is inserted into the nut, it compresses the closing plates, causing them to open downwards, providing space for the probe to extend and enter the furnace through the flame detection hole. This additional sealing mechanism significantly reduces the risk of operators coming into contact with high-temperature tar and steam when operating through the flame detection hole. Even with small gaps in the nut installation or the flame detection hole, the closing plates provide secondary protection, significantly reducing the occurrence of burns and ensuring the personal safety of operators.

[0016] 3. To prevent the furnace internal pressure from gradually increasing as the probe is inserted due to the reduced probe hole area, this utility model provides a pressure relief mechanism on one side of the upper end face of the inner convex ring. During the void detection process, pressurized gas enters the pressure relief mechanism through the pressure relief hole, compressing the piston and causing the elastic telescopic component to contract, thus separating the piston from the sealing port. At this time, the pressurized gas can enter the pressure relief mechanism through the sealing port and be discharged through the exhaust pipe at the front end via the through hole on the fixed plate. Stable furnace pressure helps to perform void detection more accurately. Pressure fluctuations can interfere with the smoothness and depth measurement of probe insertion. The pressure relief mechanism avoids this interference, allowing the probe to be inserted into the furnace more stably and obtain more accurate void data. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a blowout prevention mechanism for a generator flame detection hole, including a generator flame detection tube 1. A blowout prevention mechanism 4 is provided in the inner hole of the generator flame detection tube 1. The blowout prevention mechanism 4 includes an inner convex ring 5, which is welded and fixed to the upper end of the inner hole of the generator flame detection tube 1. A nut 6 is installed at the center of the upper end face of the inner convex ring 5. The edge of the lower end face of the nut 6 is welded and fixed to the inner convex ring 5. The axis of the nut 6 is consistent with the center hole of the generator flame detection tube 1. A flange connecting plate 2 is integrally formed on the upper end face of the generator flame detection tube 1. The flange connecting plate 2 has annularly distributed connecting holes 3 inside.

[0024] In use, an inner convex ring 5 is welded and installed into the inner liner of the generator flame detection tube 1, which facilitates the support of the nut 6 to be installed. By aligning the axis of the nut 6 with the center hole of the generator flame detection tube 1, the nut 6 is welded and fixed to the upper end face of the inner convex ring 5. After welding, the center hole of the nut 6 serves as the insertion port for the probe, and its diameter is slightly larger than the probe diameter by 0.5-1mm. This design greatly reduces the area of ​​tar and steam ejected when the generator opens the flame detection hole to measure the empty layer, effectively reducing the degree of pollution to the surrounding equipment and thus reducing the risk of burns to operators.

[0025] Please see Figure 2 and Figure 4 The bottom of the blowout preventer 4 is symmetrically provided with a closing plate 8 for automatically closing the fire detection hole. The bottom of the inner convex ring 5 is provided with a mounting groove 13. The closing plate 8 is limited inside the mounting groove 13. The closing plate 8 and the mounting groove 13 are connected by a rotating shaft. A torsion spring is installed on the outside of the rotating shaft. The two ends of the torsion spring are fixed to the closing plate 8 and the mounting groove 13 respectively. The rotation angle of the closing plate 8 is in the range of zero to ninety degrees.

[0026] When the closing plate 8 is unloaded, the two closing plates 8 seal the probe insertion hole under the elastic reset of the torsion spring. At the same time, under the limit of the inner convex ring 5, the closing plate 8 cannot continue to move upward after sealing the probe insertion hole, ensuring the stability of the sealing. When the probe is inserted into the nut 6, it squeezes the closing plate 8, thereby opening the closing plate 8 downward, providing space for the extension of the probe, so that the probe can enter the interior of the generator through the flame detection hole. The additional sealing mechanism of the closing plate 8 greatly reduces the risk of operators coming into contact with high-temperature tar and steam when operating the flame detection hole.

[0027] Please see Figure 3 and Figure 4 The pressure relief mechanism 9 includes a sleeve 10. A sealing port 14 is provided at the lower end of the sleeve 10, and the upper end of the sealing port 14 has a concave structure. A fixing plate 15 is fixedly installed at the upper end of the sleeve 10. The fixing plate 15 has multiple annularly distributed through holes 16 inside. An elastic telescopic component 17 is installed at the middle position of the bottom of the fixing plate 15. A piston 18 is installed at the bottom of the elastic telescopic component 17, and the piston 18 is adapted to the sealing port 14. The elastic telescopic component 17 consists of a fixed tube, a movable rod, and a spring assembly. The fixed tube is fixed to the bottom of the fixed plate 15, the movable rod slides with the fixed tube, and the bottom of the movable rod is fixed to the piston 18. The spring is installed on the outside of the fixed tube and the movable rod. A pressure relief mechanism 9 is provided on one side of the upper end face of the inner convex ring 5 to discharge the pressure gas generated during the probe detection of the empty layer of the generator furnace. A pressure relief hole 12 is provided on one side of the bottom of the inner convex ring 5, and the pressure relief hole 12 is connected to the bottom of the sleeve 10. An exhaust pipe 11 connected to the inner cavity is provided at the front end of the sleeve 10.

[0028] As the probe is inserted, the internal pressure of the furnace gradually increases. A pressure relief mechanism 9 is set on one side of the upper end face of the inner convex ring 5. During the empty layer detection process, the pressurized gas enters the interior of the pressure relief mechanism 9 through the pressure relief hole 12, which squeezes the piston 18, thereby causing the elastic telescopic component 17 to contract and realize the separation of the piston 18 from the sealing port 14. At this time, the pressurized gas can enter the interior of the pressure relief mechanism 9 through the sealing port 14 and be discharged through the through hole 16 on the fixed plate 15 to the exhaust pipe 11 at the front end. The stable pressure inside the furnace helps to perform empty layer detection more accurately.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
