Anti-corrosion in-place detection device

Abstract

The invention discloses an anti-corrosion in-place detection device, which comprises a trigger mechanism, a non-contact sensor and a closed container, wherein the trigger mechanism is mounted on detected equipment and moves along with the detected equipment; the triggering mechanism and the triggering end are mutually matched with the non-contact sensor to realize signal detection, and when the triggering end of the triggering mechanism moves to a triggering range along with the detected equipment, the non-contact sensor is triggered, namely the detected equipment is considered to move in place. The non-contact sensor is installed in the closed container, the closed container isolates the non-contact sensor from the outside, water vapor, dust and other impurities are prevented from influencing the non-contact sensor, the non-contact sensor is prevented from being corroded, and the detection stability is ensured.

Description

Technical field [0001] The present invention relates to the field of position detection technology, and further relates to a corrosion detection means in place. Background technique [0002] Coking region ironworks wet quenching step is an important part of the whole system of the coke oven, CDQ system overhaul, or when a fault condition, the water required by the quenching car carrying coke oven produced water to quench tower water spray quenching Jiaozuo industry to ensure the production of coke oven along the line equipment. [0003] Since the quench water tower reservoir coke quenching water containing a large amount of corrosive chemical components ammonia, benzene, phenol and the like, resulting in serious equipment corrosion field. Water quenching semaphore lock and door position detecting switch-off signal cranking limit switch employed, during manufacturing operations due to the high temperature field, a large amount of steam when put Jiaozuo industry. On-site water vapo...

AI Technical Summary

Problems solved by technology

On-site waterproof measures cannot prevent steam from entering the limit switch at all, causing water accumulation inside the limit switch, corrosion damage to the contacts and other failures, resulting in the water coke quenching control system failing to receive signals or generating false signals, which seriously affects the wet coke quenching Safe production of the system goes smoothly

[0004] For those skilled in the art, how to prevent the in-position detection device from being corroded due to the harsh working environment and ensure the detection stability is a technical problem that needs to be solved at present.
