Description
Technical Field
The invention relates to the field of solid combustion characteristic research, in particular to a long-term observation system for a combustion characteristic experimental device.
Background
The research on the solid combustion characteristics mainly aims at carrying out relevant experimental work on the combustibility and the combustion rate of plastic products, textile articles, building materials, hazardous chemical substances and the like. The flammability test is to ignite a tested object through an igniter or a gas nozzle, and observe whether the tested object can burn or not and whether the tested object can continuously burn after an external fire source is evacuated. The test is generally carried out in an open space, and instruments such as a timer, an igniter or a gas burner are arranged, so that the device is simple and has a single function. Test of solid burning Rate experiments: for example, a burning rate tester ignites a sample of a specific length through a gas nozzle, measures the burning time thereof, and thus obtains the burning rate thereof, and this method requires special preparation of the sample, such as filling a powder or pellet sample into a mold to form a long strip, and forming a paste sample into a rope; or adopt the burning box, arrange netted support in the burning box, on the support was arranged in to the sample of being surveyed, the gas nozzle that bottom or side stretched into ignited to the sample of being surveyed, closes the gas nozzle after the certain time, observes through burning box observation window whether the sample can last burning and the propagation velocity of burning flame in the burning box that has the air channel. The above methods and test devices all require exposure to a fire source,
the other method adopts a mode of electrically heating a solid sample, namely a mode of measuring the combustion temperature by using a thermocouple, and is used for researching the flash combustion temperature, the spontaneous combustion temperature or the combustion heat value. The hot air furnace heated by electric heater has a high-temp. resistant furnace tube with inlet and outlet capable of ventilating, and the measured solid is bound by metal wire. When the flash combustion temperature is measured, the air furnace is heated to a specific temperature, then the measured solid is placed in the furnace tube, the pilot flame is ignited, whether the measured sample is combusted or not is observed, and the combustion temperature of the sample is detected by a thermocouple. If the sample is not burnt under the current temperature condition, the temperature in the furnace is reduced or increased, and the test is repeated by adopting a new sample until the sample is subjected to flash combustion. And if the autoignition temperature of the sample is measured, the autoignition temperature is measured according to the method without adding pilot flame. The research is also only suitable for flammable solid materials such as plastics, woods, textiles and the like. Relevant standards such as methods or devices include GB 8410-2005 combustion characteristics of automotive interior materials, GB/T14402-2007 determination of combustion performance and combustion heat value of building materials and products, GB/T21618-2008 combustible solid combustion rate test method for hazardous articles, GB/T21580-2008 small-sized combustion test method for hazardous articles, GB/T8626-2007 flammability test method for building materials, GB/T9343-2008 determination of flash combustion temperature and spontaneous combustion temperature in plastic combustion performance test method, and the like.
The test device is not designed with a special observation device which can observe the experimental phenomenon of the experimental material or sample piece to be measured in the device on line for a long time. The general method is to observe and record the appearance state of the experimental material or the sample piece before the experiment, observe the appearance state of the experimental material or the sample piece again after the experiment, and compare the appearance states of the experimental material or the sample piece before and after the experiment to research the change of the appearance state of the experimental material or the sample piece before and after the combustion. In the experimental process, experimental observation is affected due to the closed environment of the experimental device, weak light in the initial experimental stage (experimental materials or samples do not start combustion reaction yet), and high temperature emitted by the heat loading element of the experimental device in the severe combustion stage. Even if the observation of the experimental process is carried out in individual experiments, the observation is mostly temporary observation, for example, the outer part of the experimental device adopts a material with better light transmittance, and the experimenter observes through the part or carries out limited experimental process observation records by adopting a photographing mode. On the other hand, in the case of a liquid,
the traditional technology has the following defects:
1. the original traditional shooting mode is only used for solving the problem of temporary shooting and is not a reliable technical scheme.
2. The heat radiation that high temperature produced can improve the temperature of shooting equipment, and long-time shooting can lead to the equipment to damage.
3. The inside light source that does not have when the low temperature of furnace, can't see the inside condition clearly. The high temperature is too bright, and the contrast of the shooting image is poor.
Therefore, it is necessary to develop a long-term observation system for a combustion characteristic test device to solve the above problems.

a compensation lamp 3; the compensating lamp 3 is mounted on the camera 4;
heat-insulating quartz glass 7; the heat-insulating quartz glass 7 is arranged in the heating device and fully covers the inner end of the observation hole 6;
as shown in figure 1, the heating device comprises a hearth, a heating element 8 and an insulating layer 9, wherein the heating element 8 is arranged inside the hearth, and an observation hole 6 is formed in the top of the hearth. An insulation layer 9 is mounted in the furnace and arranged around the heating element 8.
Take a general-purpose combustion characteristic experimental apparatus (high-temperature heating furnace) as an example: the periphery of the high-temperature hearth is wrapped with the heat-insulating layer 9, so that the temperature inside the high-temperature hearth can reach more than 1600 ℃. The inner wall of the high heat-insulating layer 9 is provided with a heating element 8, and after the heating element 8 is electrified, the high brightness and high heat phenomena are generated inside the hearth.
A piece of heat-insulating quartz glass 7 is arranged at the inner end of the observation hole 6 so as to prevent high-temperature air in the hearth from flowing into the observation hole 6 and causing the temperature of the observation hole 6 to be too high. A piece of dustproof quartz glass 5 is installed at the top of the observation hole 6, and the dustproof quartz glass 5 can isolate external dust, so that the cleanness inside the observation hole 6 is kept, and the phenomenon that the dust is attached to the inner surface of the glass to influence observation is avoided.
A refractor 1 is arranged above the dustproof quartz glass 5, and the refractor 1 can transmit the image inside the hearth out, and the image is projected on the camera 4 after the angle is converted. The back of the refractor 1 is provided with a radiating fin which can reduce the heat of the refractor 1. After the light source is refracted, the refractor 1 absorbs certain heat energy, so that the temperature transmission can be reduced, and the camera 4 is prevented from being baked at high temperature. A camera 4 is arranged in the refraction direction of the refractor 1, the camera 4 is opposite to the refractor 1, and the condition in the hearth is observed through the refractor 1. Between camera 4 and refractor 1, set up an automatic change light filter 2, this lens can automatically regulated filtering intensity, and when the inside low temperature of furnace, light is very low, and the filter reduces filtering intensity automatically, makes camera 4 can be fine shoot the state of furnace. When the inside high temperature of furnace, light is stronger, and the filter improves filtering strength, makes camera 4 can filter the light of hi-lite, shoots out clear formation of image.
Above camera 4, set up a compensating lamp 3, when needs shoot the record in to furnace, compensating lamp 3 is opened, inside illuminating furnace, makes it can clearly observe.
The working principle is as follows:
the heating element 8 is electrified to generate high temperature and high brightness, and the temperature can reach more than 1600 ℃ at most. In the temperature rise process, the hearth is sealed at the periphery and cannot transmit light, so that the interior is dark and bright at low temperature. At high temperature, the heating element 8 can generate high brightness and high heat, the hearth can be completely illuminated, and the camera 4 can be influenced to a certain degree by overhigh brightness, such as overexposure and low contrast.
The camera 4 is arranged outside the hearth and observes inside the observation hole 6 formed in the top of the hearth. In order to prevent the inside high-temperature air from overflowing, a piece of heat-insulating quartz glass 5 is installed at the bottom of the observation hole 6, the high-temperature air cannot pass through the observation hole 6, the observation hole 6 cannot be baked by hot air, and the hot air cannot overflow out of the hearth through the observation hole 6.
A piece of dustproof quartz glass 5 is installed at the top end of the observation hole 6, and after the dustproof quartz glass 5 and the heat insulation quartz glass 7 block two ends of the observation hole 6, external dust and air cannot enter, so that the inner surfaces of the dustproof quartz glass 5 and the heat insulation quartz glass 7 are always kept clean, and dust does not adhere to the inner surfaces of the quartz glass to influence observation sight.
A90-degree refractor 1 is arranged right above the observation hole 6, and the refractor 1 is arranged at an angle of 45 degrees, so that an image projected from the lower part is projected in the horizontal direction. Meanwhile, the back of the refractor 1 is provided with a radiating fin, the purpose is to ensure that after a part of heat is absorbed by light with heat radiation, the opposite camera 4 is thrown down, so that the camera 4 receives less heat radiation, and the device is damaged due to overhigh heat.
After the camera 4 is opened, the incoming line shooting in the high-temperature hearth can be continuously carried out for a long time. Because the light ray can be changed greatly when the high-temperature hearth works, the light ray gradually becomes high and bright from complete darkness to rise of temperature. The large variation of the light source causes difficulty in lighting by the camera 4.
When the light source is darker, the compensation lamp 3 above the camera 4 provides the light source to the hearth to illuminate the environment in the hearth, so that the camera 4 can shoot clear images.
Along with the rise of the temperature, the heating element 8 in the hearth can gradually emit light and shine, when the temperature exceeds 1000 ℃, the light becomes stronger, and the camera 4 shoots a picture to be white and the picture is in an overexposed state. At this time, the automatic light-changing filter 2 in front of the camera 4 can adjust the filtering intensity of the automatic light-changing filter, and strong light is filtered out, so that the intensity of projection light received by the camera 4 is ensured to be suitable, and a cleaning imaging effect is achieved.
The automatic light-changing filter 2 has the functions of manual setting and automatic light-changing filtering. By setting the imaging effect after filtering in advance, the purpose of automatically adjusting the filtering strength can be achieved during formal operation, so that the camera 4 can obtain the best imaging effect.
1. Overall System design
The total design of this application adopts high temperature furnace + observation hole + structure of making a video recording + light source control. The high-temperature hearth is used as a heating component of the experimental equipment and consists of a heating element, a heat-insulating layer and the like. The high-temperature hearth heats the sample piece to a high-temperature state, and then observation is carried out through the observation hole above the sample piece. The observation hole is made of quartz glass, and comprises heat insulation quartz glass for blocking the high temperature of the hearth and dustproof quartz glass for observation. A camera is arranged outside the hearth and shoots the state in the hearth through a refractor. The light in the hearth has the change of intensity, and the light source projected onto the camera is adjusted to a proper light intensity through the external automatic light-changing filter and the compensating lamp, so that the imaging quality is improved.
2. Controllable design of imaging light source
The high-temperature hearth is a closed cavity, the light source carried by the high-temperature hearth is a heating element, but the light intensity generated by the heating element in different temperature ranges is not consistent, and the light source cannot be generated in a low-temperature range (below 400 ℃), when the temperature reaches 400 ℃ -700 ℃, the light source generated by the heating element is red, and the higher the temperature is, the more the hearth is changed from red to white, and the higher the brightness is.
The camera has the advantages that the compensation lamp is additionally arranged above the camera, when light rays in the hearth are dark, the light source is projected to the hearth through the compensation lamp, the sample piece is illuminated, and clear pictures can be shot by the camera.
When the light is strong, the automatic light-changing filter in front of the camera can filter the strong light into a light source suitable for the camera.
3. Heat-insulation dustproof observation hole
In order to facilitate the observation of the condition inside the hearth, an observation hole is formed in the top heat-insulating layer. The observation hole is used for blocking heat in the hearth, a heat insulation quartz plate is arranged inside the observation hole, and the quartz plate can prevent high-temperature air inside the observation hole from flowing out of the hearth through the observation hole.
In order to prevent dust from adhering to the quartz plate to affect observation after long-time use, a piece of dustproof quartz glass is arranged on the other side of the heat-insulating layer. A sealed cavity is formed between the dustproof quartz glass and the heat insulation quartz glass, and external dust cannot enter the sealed cavity, so that the sealed cavity can be better observed.
4. Thermal isolation design for camera
In the high temperature state, the temperature is transmitted by radiation, and the camera cannot bear the high temperature. The design reduces the influence of high temperature on the camera through two aspects. Firstly, can absorb some heats after refracting through the refractor, the fin that has behind the refractor back can be with its heat dissipation. And secondly, the automatic light-changing filter in front of the camera can filter light, heat is transferred at high temperature through radiation, and when the heat passes through the automatic light-changing filter, part of the heat is filtered by the light-changing filter.
Through the design, the influence of high temperature on the camera is reduced to the minimum, and the long-time shooting work on a high-temperature sample can be met.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
