Description
Technical Field
The utility model relates to an oil smoke detection area specifically is to relate to an oil smoke detection device.
Background
The patent of CN201820728603.7 provides an oil smoke detection device, its scheme is that inserts a sampling box in the oil smoke pipeline, passes the oil smoke through the laser transmitter transmission laser in the sampling box after by laser receiver receipt laser and by the light intensity information that processing module handled received and obtain oil smoke concentration data, wherein, when the oil smoke got into the sampling box, can directly contact with laser transmitter, pollute laser transmitter's transmission port easily, influence the transmission effect of laser.
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving prior art problem, provide an oil smoke detection device, can avoid the oil smoke to laser emitter's pollution.
In order to achieve the above object, the utility model provides an oil smoke detection device, include
The detection box comprises a box body;
the detection pipe is of a transparent pipe body structure, is arranged in the box body and is arranged on the smoke exhaust pipeline, is positioned on the smoke exhaust passage and is suitable for oil smoke to pass through;
the laser emitter is arranged in the box body, and an emitting port of the laser emitter is opposite to the pipe wall of the detection pipe;
the laser receiver is arranged in the box body and is suitable for receiving laser emitted by the laser emitter;
and the processing module is suitable for processing the light intensity information received by the laser receiver.
Compared with the prior art, the utility model discloses when the inside oil smoke of well exhaust pipe passes through the detecting tube, the laser of laser emitter transmission is received by laser receiver after passing through detecting tube and its inside oil smoke, and received laser carries out signal processing by processing module, and the oil smoke passes through in by the detecting tube, not with laser emitter and laser receiver direct contact, has avoided the oil smoke to laser emitter and laser receiver's pollution.

Reference numerals: 1. a box body; 101. an air inlet; 102. an air outlet; 2. a laser transmitter; 3. a laser receiver; 4. and (6) detecting the tube.
Detailed Description
The existing oil smoke detection device needs to introduce oil smoke into the detection box through the air exhaust device after an opening is formed in the oil smoke pipeline to be detected and then discharged when the detection box is connected to the oil smoke pipeline, and the structure is very complex, so that the production and processing processes are multiple, and the cost is high during production and processing. Aiming at the problem, the scheme provides an oil smoke detection device which comprises a detection box and a detection device, wherein the detection box comprises a box body 1; the detection pipe 4 is of a transparent pipe structure, the detection pipe 4 is arranged inside the box body 1, and the detection pipe 4 is arranged on the smoke exhaust pipeline, is positioned on the smoke exhaust passage and is suitable for oil smoke to pass through; the laser emitter 2 is arranged inside the box body 1, and an emitting port of the laser emitter 2 is opposite to the pipe wall of the detection pipe 4; the laser receiver 3 is arranged inside the box body 1, and the laser receiver 3 is suitable for receiving laser emitted by the laser emitter 2; a processing module (not shown in the figure) adapted to process the light intensity information received by the laser receiver 3.
In this embodiment, will insert a detecting tube 4 of transparent structure on oil smoke pipeline, this detecting tube 4 is located the passageway of oil smoke, the oil smoke can pass through detecting tube 4 at the operation in-process, detecting tube 4 separates the oil smoke with laser emitter 2 and laser receiver 3, the oil smoke has been avoided to pollution between them, compare prior art, this scheme still need not to install air exhaust device with the oil smoke suction detection case, the structure has been simplified, production cost is reduced, need not be at oil smoke pipeline pipe wall upper shed, insert the detection case again, because general oil smoke pipeline is cylindrical, the opening is special-shaped mouth on the pipe wall, compare plane opening technology with man-hour more complicated.
The detection tube 4 is a homogeneous transparent tube structure, and can ensure the penetrability of laser when in use.
When the smoke exhaust pipe is used specifically, when oil smoke in the smoke exhaust pipe passes through the detection pipe 4, laser emitted by the laser emitter 2 passes through the detection pipe 4 and the oil smoke in the smoke exhaust pipe and then is received by the laser receiver 3, and the received laser is subjected to signal processing by the processing module.
Natural light can exist outside the box body 1, when the laser receiver 3 receives laser light, if the natural light enters the box body 1, the laser light can be influenced to be received, and further the detection result is interfered. When the device is used specifically, the box body 1 can be made of steel, the oil smoke pipeline penetrates through the air inlet 101 on one surface of the box body 1 and penetrates out of the air outlet 102 on the other opposite surface, and the section located inside the box body 1 is the detection pipe 4.
In order to reduce the processing materials, ensure compact structure and avoid excessive refraction of light, the detection tube 4 of the present embodiment is a straight tube, and the laser emitted by the laser emitter 2 is perpendicular to the axis of the detection tube 4. When laser passes through the detecting tube 4, the laser is received by the laser receiver 3 after being refracted by the tube wall of the detecting tube 4 and then being refracted by the tube wall of the detecting tube 4 and penetrating out, the number of times of refraction of the laser in the process is minimum, the material for manufacturing the detecting tube 4 is also minimum, the straight tube also enables the space of the box body 1 to be smaller and the structure to be more compact under the condition of satisfying the oil smoke detection.
Various modifications and variations of the embodiments of the present invention may be made by those skilled in the art, and they are within the scope of the present invention provided they are within the scope of the claims and their equivalents. What is not described in detail in the specification is prior art that is well known to those skilled in the art.
