Description

Technical Field

[0001] The utility model relates to the technical field of detection and protection, in particular to a flame detector protection device. Background Art

[0002] The flame detector is an important device in the heater safety monitoring system. Its function is to detect the combustion conditions in real time according to the combustion characteristics of the flame. Once the flame combustion state does not meet the normal conditions or is extinguished, a signal is given in a certain way to ensure that the fuel supply is stopped when the heater is extinguished. It is mainly composed of two parts: the probe and the signal processor. Usually, the flame detector detects the flame in the furnace through the connecting pipe. If foreign matter falls into the connecting pipe and blocks the lens of the flame detector, it will cause detection failure and device shutdown.

[0003] For example, a Chinese patent with publication number CN214891327U discloses a flame detector protection device, comprising: a body arranged at one end of the flame detector, the body comprising a protection net, the protection net being a tubular hollow structure, the end of the protection net away from the flame detector being a closed structure, and the protection net being arranged in a connecting pipe;

[0004] The technical solution recorded in this scheme can effectively isolate foreign objects from the flame detector's lens line of sight by setting a protective net between the flame detector and the connecting pipe, preventing foreign objects from entering the flame detector's detection channel and causing obstruction, resulting in a decrease in the flame detector's detection accuracy or detection failure. However, when this scheme is in use, although the protective net can isolate foreign objects, it is easy to block the flame detector's lens line of sight, thereby affecting the detection effect.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a flame detector protection device is provided to achieve a purpose with greater practical value. Utility Model Content
