Description

Technical Field

[0001] The utility model relates to the technical field of temperature measuring thermocouples, in particular to a temperature measuring thermocouple for a waste incinerator. Background Technique

[0002] A thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures temperature, converts the temperature signal into a thermoelectromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument. The outer shapes of various thermocouples are often very different due to requirements, but their basic structures are roughly the same. They usually consist of main parts such as thermal electrodes, insulating sleeve protection tubes, and junction boxes, and are usually used in conjunction with display instruments, recording instruments, and electronic regulators.

[0003] For example, the patent document with the publication number CN 211373865 U discloses a temperature measuring thermocouple for a waste incinerator, including a furnace body. An installation plate is fixedly connected through the interior of the furnace body. A first through hole is opened at the center position of the outer surface of the installation plate. A scraping pipe is fixedly connected to the outer surface of the installation plate close to the interior of the furnace body. A flange fixedly connected by bolts is provided on the outer side of the installation plate close to the outside of the furnace body, and a second through hole is opened at the center position of the flange. In the utility model, the motor rotates to drive the gear to rotate, the gear rotates to drive the toothed ring to rotate, the toothed ring rotates to drive the threaded cylinder to rotate on the rotating seat, and the threaded cylinder rotates to drive the connecting pipe to rotate and move through the thread, so that the thermocouple and the scraping pipe move relative to each other, thereby scraping off the slag on the surface of the thermocouple, thereby improving the measurement accuracy of the thermocouple. At the same time, the connecting pipe and the flange can be fitted together through the locking nut and the sealing gasket to avoid leakage.

[0004] However, when this structure is used for temperature measurement of a waste incinerator, it is impossible to perform sealing protection operations on the interface between the thermocouple device that moves back and forth and the sleeve. Leakage is likely to occur after long-term use at the moving position, and it cannot provide safer protection for the thermocouple device. At the same time, the device cannot perform overall positioning and locking fixation operations on the thermocouple device, and cannot meet the daily use requirements. Therefore, it is urgent to design a temperature measuring thermocouple for a waste incinerator to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a temperature measuring thermocouple for a waste incinerator to solve the problems raised in the above background technique that when the existing structure is used for temperature measurement of a waste incinerator, it is impossible to perform sealing protection operations on the interface between the thermocouple device that moves back and forth and the sleeve, leakage is likely to occur after long-term use at the moving position, it cannot provide safer protection for the thermocouple device, and at the same time, the device cannot perform overall positioning and locking fixation operations on the thermocouple device, and cannot meet the daily use requirements.

[0015] The thermocouple for measuring temperature in a waste incinerator further improves the overall use effect of the equipment through the provided fixed side frame, sealing tube sleeve, annular airbag, tightening ring, thermocouple body, inner piston sleeve, annular scraper, suction fan, air inlet valve port and uniform air duct. During daily use, the staff can start the suction fan at the top of the fixed side frame, and inflate the annular airbag inside the two sealing tube sleeves from the air inlet valve port and the uniform air duct at the top of the fixed side frame and the installation groove, so that the annular airbag tightens the tightening ring, and thus the thermocouple body moving inside the fixed side frame can be quickly fixed and protected, avoiding the problem of loosening back and forth during subsequent use, reflecting the comprehensiveness of the equipment design.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , an embodiment provided by the present invention:

[0023] A thermocouple for measuring temperature in a waste incinerator, comprising a fixed side frame 1, an installation groove 2 is formed on the side surface of the fixed side frame 1, sealing pipe sleeves 3 are arranged at both ends of the inner wall of the fixed side frame 1, an annular airbag 4 is arranged on the inner wall of the sealing pipe sleeve 3, a tightening ring 5 is arranged on the inner wall of the annular airbag 4, fitting arc pieces 15 are fixedly connected to both sides of the fixed side frame 1, an air suction fan 16 is arranged at the top of the fixed side frame 1, an air inlet valve port 17 is formed at the top of the fixed side frame 1, and an air distribution duct 18 is arranged at the top of the installation groove 2. Start the air suction fan 16 at the top of the fixed side frame 1, so that it inflates the annular airbag 4 inside the two sealing pipe sleeves 3 from the air inlet valve port 17 and the air distribution duct 18 at the top of the fixed side frame 1 and the installation groove 2, so that the annular airbag 4 tightens the tightening ring 5.

[0024] A thermocouple body 6 is movably connected inside the fixed side frame 1. Measuring strips 7 are arranged on the four sides of one end of the thermocouple body 6. A positioning ring 8 is arranged at the center of the side surface of the thermocouple body 6. Conical seals 9 are arranged at both ends of the thermocouple body 6. Limit balls 10 are fixedly connected to both ends of the thermocouple body 6 through the conical seals 9. An outer piston sleeve 11 is fixedly connected to one end of the fixed side frame 1. A sealing inner ring 12 is arranged on the inner wall of the outer piston sleeve 11. An inner piston sleeve 13 is fixedly connected to the other end of the fixed side frame 1. An annular scraping knife 14 is arranged at one end of the inner piston sleeve 13. The fitting arc pieces 15 on both sides of the fixed side frame 1 are adaptively docked and installed with the side surface of the waste incinerator. At this time, the thermocouple body 6 can be limited by the conical seals 9 and the limit balls 10 at both ends, and can be reciprocally pulled and adjusted inside the fixed side frame 1, so that the measuring strips 7 on the side surface of the thermocouple body 6 can be protected inside the waste incinerator.

[0025] Working principle: When in use, the user first fixedly installs the entire fixed side frame 1 on the side wall of the waste incinerator through the mounting groove 2 on the side. Then, the fitting arc pieces 15 on both sides of the fixed side frame 1 are adaptively docked and installed with the side of the waste incinerator. At this time, the thermocouple body 6 can be limited by the tapered seals 9 and the limit balls 10 at both ends and perform a reciprocating adjustment operation inside the fixed side frame 1, so that the measurement strip 7 on the side of the thermocouple body 6 can be protected inside the waste incinerator. The positioning ring 8 at the center of the side of the thermocouple body 6 is positioned during the reciprocating movement. At the same time, the tapered seals 9 at both ends of the thermocouple body 6 can be tightly sealed against the inner sealing rings 12 of the outer piston sleeves 11 and the inner piston sleeves 13 at both ends of the fixed side frame 1 to ensure the airtightness inside the fixed side frame 1 and prevent the gas inside the waste incinerator from overflowing. During daily use, the staff can start the suction fan 16 at the top of the fixed side frame 1 to inflate the annular air bags 4 inside the two sets of sealing pipe sleeves 3 from the air inlet valve openings 17 and the uniform air ducts 18 at the top of the fixed side frame 1 and the mounting groove 2. As a result, the annular air bags 4 tighten the tightening rings 5, so that the movable thermocouple body 6 inside the fixed side frame 1 can be quickly fixed and protected, avoiding the problem of loosening back and forth during subsequent use. The above is the entire working principle of the present utility model.
