Description
Technical field
It the utility model is related to a kind of infrared flame detector.
Background technology
Infrared flame detector traditional at present, because the degree of protection of shell is inadequate, the Frequency Band Selection of flame sensor
Unreasonable, the fire that place be present for be corrosive gas or the liquid of industrial circle can not protect well, flame
Detector is often corroded and broken down, or in this liquid place while in the presence of also having heat of being corrosive, it is impossible to very
Flame detecting is carried out well, and wrong report is a lot.
Utility model content
The purpose of this utility model is to provide a kind of infrared flame detector, and it can solve of the prior art above-mentioned scarce
Point.
The utility model uses following technical scheme：
A kind of infrared flame detector, including upper lid and bottom box, and upper lid is fastened with back box by rotary buckle, the bottom
A radome is provided with inside box, and the radome is fixedly provided with dual frequency transducer, the upper lid is provided with a watch window.
The outside of the radome is provided with aluminium alloy sensor stand, and one layer of jewel piece is provided with aluminium alloy post.
The dual frequency transducer is 4.43 μm of arrowbands of bispectrum and 5.5-6.3 μm of broadband sensor.
The material of the upper lid and bottom box is PP materials.
The utility model has the advantages that：The shell mechanism made using special PP materials, coordinates new bispectrum flame
Detection Techniques, I P67 requirement of shelter can be met, practical there can be place in the moist, liquid that is corrosive, carry out flame
Detection.Anticorrosion flame detector is compact-sized, internal embedding, and intrinsic safe explosion-proof design, security function is complete, connection and reasonable arrangement, makes
It is outstanding with performance.Suitable for the particular surroundings application of semicon industry, solar energy industry, lithium battery industry etc..

Embodiment
Specific embodiment of the present utility model is expanded on further below in conjunction with the accompanying drawings：
As shown in Fig. 1 to Fig. 8 a kind of infrared flame detector, including upper lid 2 and back box 1, and upper lid 2 passes through rotation with back box 1
Turn buckle fastening, be provided with a radome 7 inside the back box, and the radome 7 be fixedly provided with detector circuit plate and pair
Video sensor 5, the upper lid are provided with a watch window 3.The outside of the radome is provided with aluminium alloy sensor stand, and aluminium
One layer of jewel piece 4 is installed on alloy bracket.The dual frequency transducer is 4.43 μm of arrowbands of bispectrum and 5.5-6.3 μm of broadband
Sensor.The material of the upper lid and bottom box is PP materials.
It is insufficient present in anticorrosion place that the utility model mainly solves prior art, there is provided a kind of structure letter
Single, performance is outstanding, and degree of protection is high, reliable and stable anticorrosion infrared flame detector.This
Back box of the present utility model and upper lid are made of PP materials, and the upper lid camera lens face of particular design is anti-reflection design,
It is next using turn buckle between upper lid and bottom box, closed with PUR.
There is a radome in the centre of box, have detector circuit plate and dual frequency transducer inside radome.
Sensor front end employs new double-layer lens structure, employs aluminium alloy sensor stand, is mounted with support
One layer of jewel piece with the PP eyeglasses for closing lid, forms air exclusion layer, effectively prevents the shadow of hot object as first layer eyeglass
Ring.
Using new 4.43 μm of arrowbands of bispectrum and 5.5-6.3 μm of broadband combination technology, can remove hot object influences, and two
The infrared sensor of individual different spectral and different frequency ranges detects to flare up fire and interference signal, so as to realize to flame with
The resolution of interference, the detection signal of two-way sensor is after amplification and processing, while input system processor carries out digital filter
Ripple processing, and the related fire model in memory be present to the recognizer contrast of combination of frequency using flame spectrum and compare,
Provide fire alarm signal.
Detector uses intrinsic safe explosion-proof circuit design, output is exported using solid-state relay, can be applied in explosion-proof field
Institute, output lead are the high-protection level that WATERPROOF PACKING GLAND and encapsulating combine, and overall detector meets IP67 degree of protection.
Circuit design of the present utility model is to pacify explosion-proof type, solid-state relay signal output.Double-deck infrared lens design, has
The removal hot object of effect influences.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
