Description

Technical Field

[0001] The utility model relates to the field of ceramic protection tubes, in particular to a ceramic protection tube cracking alarm mechanism. Background Art

[0002] Ceramic protective tube is a protective tube used for thermocouples, sensors and other equipment, usually made of high temperature alloy, aluminum oxide, silicon carbide and other materials. The characteristics of this tube are that it can withstand high temperature, corrosion resistance, wear resistance, oxidation resistance, etc., thus effectively protecting the internal equipment. When using ceramic protective tubes, it is easy to crack due to external impact. If the cracked protective tube continues to be used, it is easy for the external liquid to contact the internal heating components, causing water intrusion and damage to the heating components.

[0003] After searching, the application number is "202122343586.X", which provides a ceramic protective tube cracking alarm mechanism. When using this device, the staff will install the ceramic protective tube cracking alarm mechanism inside the ceramic tube. Then when the ceramic tube cracks, the aluminum liquid will leak into the ceramic tube and contact the trigger electrode, and then transmit the signal to the bursting tube electrode to make the two electrodes conductive, forming a loop. When the PLC device receives the signal, it will first activate the cut-off device to cut off the power supply of the heating element, and at the same time activate the alarm device to remind the staff.

[0004] When the above-mentioned protective tube cracks, the alarm device will remind the staff to carry out maintenance, but it only reminds the staff. When water enters the ceramic protective tube, the staff needs to pull out the heating component in time. If it is not pulled out in time, the heating component is easy to come into contact with the accumulated water at the bottom of the protective tube, making the heating component easy to enter water and be damaged. Utility Model Content

[0025] The alarm unit 4 includes a power connection block 401, which is arranged on the upper side of the cover plate 2. An alarm 404 is fixedly connected to the upper side of the power connection block 401, a heating tube 402 is fixedly connected to the lower side of the power connection block 401, a micro pressure plate 406 is fixedly connected to the lower end of the heating tube 402, an electric push rod 405 is fixedly connected to the upper side of the cover plate 2, an output end of the electric push rod 405 is fixedly connected to the micro pressure plate 406, a connecting line 403 is fixedly connected between the micro pressure plate 406 and the alarm 404, the heating tube 402 is slidably connected to the cover plate 2, and there are multiple electric push rods 405. When the ceramic protective tube body 1 cracks, external liquid penetrates through the cracks. The infiltrated liquid flows into the interior of the ceramic protective tube body 1 and onto the micro pressure plate 406. At this time, the micro pressure plate 406 detects the pressure data, so that the signal of the micro pressure plate 406 passes through the connecting line 403, and the alarm 404 is activated, so as to remind the staff in time. At the same time, the external PLC controller controls the extension and retraction of the electric push rod 405, and the electric push rod 405 drives the micro pressure plate 406 to rise, and the micro pressure plate 406 drives the heating tube 402 to rise, and the heating tube 402 drives the power connection block 401 and the alarm 404 to rise, so that the heating tube 402 moves to the upper area of ​​the ceramic protective tube body 1 to avoid the contact between the bottom water and the heating tube 402, and to avoid the damage of the heating tube 402 by the liquid.

[0026] A mounting ring 3 is fixedly connected to the lower side of the cover plate 2, an inner side of the mounting ring 3 is provided with an internal thread 5, an outer side of the ceramic protection tube body 1 is provided with an external thread 6, and the mounting ring 3 is threadedly connected to the ceramic protection tube body 1. When the staff finds that the ceramic protection tube body 1 is cracked, the mounting ring 3 is rotated to separate the mounting ring 3 from the ceramic protection tube body 1, so that the cover plate 2 can be removed conveniently, and the heating tube 402 on the lower side can be removed for maintenance.

[0027] Working principle: When the ceramic protective tube body 1 cracks, the external liquid penetrates into the interior of the ceramic protective tube body 1, the micro pressure plate 406 detects the pressure data, and then reminds the staff of the cracks of the ceramic protective tube body 1 through the alarm 404. At the same time, the external PLC controller controls the electric push rod 405 to drive the micro pressure plate 406 to rise, and the micro pressure plate 406 drives the heating tube 402 to move to the upper area to prevent the external liquid from damaging the heating tube 402.
