Abstract
Description
Technical Field
[0001] This invention belongs to the field of burner testing technology, and specifically relates to a burner comprehensive performance testing device. Background Technology
[0002] The burner comprehensive performance testing device is a specialized device used to monitor core performance parameters of burners such as combustion temperature, combustion product concentration, and flame state. It is widely used in industrial burner production testing, daily operation and maintenance calibration, combustion efficiency evaluation, and other fields, providing important data support for burner performance optimization, fault diagnosis, and compliance testing.
[0003] In existing burner comprehensive performance testing devices, the flame detection camera, as the core component for capturing flame conditions, directly affects the accuracy of the test data due to its operational stability. However, during actual testing, the high temperatures and sparks generated by burner combustion can easily cause impact or baking damage to the flame detection camera. Simultaneously, the high brightness at the flame center directly illuminates the camera sensor, leading to overexposure, resulting in blurred flame images and loss of detail, thus affecting the flame condition detection effect and failing to meet the requirements for efficient and accurate testing. Therefore, it is necessary to design a comprehensive burner performance testing device. Summary of the Invention
[0004] The purpose of this invention is to provide a burner comprehensive performance testing device with a simple structure and reasonable design in order to solve the above-mentioned problems.
[0005] The present invention achieves the above objectives through the following technical solutions: A comprehensive performance testing device for burners includes a testing chamber containing an insulation layer and a control box. The control box contains a control module. An exhaust channel is located at the top of the insulation layer, and a gas sensor is installed on the insulation layer near the exhaust channel. A combustion-supporting gas supply device is installed in the control box, and its output end is connected to a gas supply pipe that penetrates the insulation layer. A flame detection camera is fixedly installed in a groove in the insulation layer. A protective mechanism is located on the inner wall of the insulation layer near the flame detection camera. The protective mechanism includes mounting frames symmetrically fixed to the inner wall of the insulation layer, mounting frames with mounting frames, and an outer protective layer mounted on the mounting frames. An anti-exposure mechanism and a surface cleaning mechanism are provided on the mounting frames. The anti-exposure mechanism includes a rotating column rotatably connected to the mounting frame via a damping bearing. A filter holder is fixedly mounted on the rotating column, and a filter to prevent overexposure of the flame detection camera is mounted on the filter holder. A drive gear is provided on the rotating column.
[0006] As a further optimization of the present invention, the surface cleaning mechanism includes guide rails symmetrically fixed between the mounting frames. The guide rails include a cleaning section parallel to the outer protective layer and a flipping section having a certain angle with the outer protective layer. The slides on the cleaning section and the flipping section are interconnected, and a cleaning frame that fits the mounting frame and the outer protective layer is slidably connected in the slides of the cleaning section and the flipping section.
[0007] As a further optimization of the present invention, the top of the cleaning frame is rotatably connected to a connecting block, and a slag removal mechanism is provided on the connecting block. The slag removal mechanism includes a support frame fixed on one of the flip sections, a connecting shaft rotatably connected in the support frame, an upper gear fixedly sleeved on the top of the connecting shaft, and elastic plates evenly arranged at the bottom of the connecting shaft. A striking strip is fixed at one end of the elastic plate.
[0008] As a further optimization of the present invention, an upper rack is slidably connected to one side of the connecting block, and one end of the upper rack is fixed to the driving mechanism. The driving mechanism includes a driving frame fixed to one end of the upper rack. The driving frame is slidably connected to the connecting block through a guide rod, and a support spring sleeved on the guide rod is provided between the driving frame and the connecting block.
[0009] As a further optimization of the present invention, the drive frame is slidably connected to the guide rod, and the guide rod is fixed between the mounting frames.
[0010] As a further optimization of the present invention, a lower rack is fixed at the bottom end of the drive frame, and the drive frame is fixedly connected to the output end of the drive electric cylinder.
[0011] As a further optimization of the present invention, the drive electric cylinder is fixedly connected in the heat insulation shell, and the heat insulation shell is fixed on the inner wall of the heat insulation layer, and a temperature sensor for detecting temperature is installed in the heat insulation layer.
[0012] As a further optimization of the present invention, a buffer sleeve is abutting between the mounting bracket and the heat insulation layer, the buffer sleeve is sleeved on the support sleeve, and the support sleeve is fixedly sleeved on the mounting bracket.
[0013] As a further optimization of the present invention, the testing chamber is provided with a flip door, and the flip door is provided with a handle and an observation window.
[0014] The beneficial effects of this invention are as follows: 1. During operation, the high temperature and sparks generated by the burner directly affect the protective mechanism. The outer protective layer is made of transparent alumina ceramic, which can directly isolate the high temperature radiation and sparks, preventing the camera from being damaged by the impact of the sparks or by the high temperature. At the same time, during the operation of the flame detection camera, the filter of the anti-exposure mechanism is always between the flame and the camera, which can effectively reduce the high brightness of the flame center and prevent strong light from directly shining on the camera and causing overexposure. This ensures that the camera can clearly capture dynamic data such as flame shape and pulse frequency, and avoids detection interruption and data distortion due to camera damage or exposure. This extends the service life of the camera and ensures the smooth progress of the detection work.
[0015] 2. The present invention drives the electric cylinder to move the cleaning frame along the cleaning section of the guide rail. The flexible scraping surface on one side of the cleaning frame is closely attached to the surface of the outer protective layer. During the sliding process, various impurities are swept away, ensuring that the outer protective layer remains transparent and does not block the camera lens. This ensures that the flame detection camera can always collect clear flame images, indirectly improving the detection accuracy of core performance parameters such as burner combustion status and combustion efficiency.
[0016] 3. In this invention, when the cleaning frame slides to the end of the flipping section and is blocked, the drive frame compresses the support spring, causing the upper rack to mesh with the upper gear of the slag removal mechanism. Through the meshing of the rack and gear, the connecting shaft rotates. The elastic plate at the bottom of the connecting shaft drives the striking bar to make a circular motion under the action of centrifugal force, repeatedly striking the flexible cleaning surface to shake off the residual residue adhering to the cleaning surface. During the reset process, the striking bar will vibrate in the opposite direction to further ensure that the residue is completely removed, so that the flexible cleaning surface remains clean at all times, ensuring the effect of each subsequent cleaning and avoiding the impact of residue residue on the transparency of the outer protective layer and the imaging quality of the camera.
[0017] 4. When the filter needs to be replaced, the drive cylinder retracts, pulling the drive frame away from the outer protective layer. The lower rack at the bottom of the drive frame moves with the drive frame and meshes with the drive gear of the anti-exposure mechanism. The movement of the lower rack drives the rotating column to rotate 180 degrees against the friction of the damping bearing, thereby driving the filter holder to rotate synchronously. This enables the rapid replacement of filters of different specifications at both ends of the filter holder. After the replacement is completed, the rotating column remains stable under the action of the damping bearing to prevent self-rotation. The filter replacement can be completed without disassembling any parts, without interrupting the detection process. It is suitable for different flame intensities and different detection dimensions, greatly improving the versatility and detection flexibility of the device. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0021] Example: Please refer to Figures 1-6A comprehensive performance testing device for burners includes a testing chamber 1, an insulation layer 2 and a control box 3 inside the testing chamber 1, and a control module inside the control box 3. An exhaust channel 4 for discharging combustion gases is located on the top of the insulation layer 2. A gas sensor for detecting combustion products is installed on the insulation layer 2 near the exhaust channel 4. A hinged flip door 10 is connected to the testing chamber 1, and the flip door 10 has a handle and an observation window 11 for easy external observation. A temperature sensor for detecting temperature is installed on the insulation layer 2. A combustion gas supply device for providing combustion-supporting gas is installed in the control box 3 (the combustion gas supply device is prior art and will not be described in detail here). The output end of the combustion gas supply device is connected to a gas supply pipe 5, which is fixedly inserted through the insulation layer 2. The combustion gas supplied by the combustion gas supply device is mixed with oxygen and then transported to the internal space of the insulation layer 2 through the gas supply pipe 5. A flame detector for monitoring the flame state is fixedly installed in a groove inside the insulation layer 2. Camera 6 (Flame detection camera 6 is existing technology and will not be described in detail here). A protective mechanism 7 for protecting the flame detection camera 6 is provided on the inner wall of the heat insulation layer 2 near the flame detection camera 6. The protective mechanism 7 includes four mounting brackets 71 symmetrically fixed on the heat insulation layer 2. The four mounting brackets 71 are fixed to the mounting frame 72 by bolts. An outer protective layer 73 is fixedly installed in a through groove on one side of the mounting frame 72. The outer protective layer 73 is made of alumina transparent ceramic material, which can resist high temperature and prevent the splashes generated by combustion from damaging the camera. A buffer sleeve 74 for providing cushioning is abutted between the mounting bracket 71 and the heat insulation layer 2. The buffer sleeve 74 is fitted on the support sleeve 75, and the support sleeve 75 is fixedly fitted on the mounting bracket 71. An anti-exposure mechanism 8 and a surface cleaning mechanism 9 are provided on the mounting frame 72. The anti-exposure mechanism 8 plays a role in light reduction protection, preventing the high brightness of the flame center from directly shining on the flame detection camera 6 and causing the flame detection camera 6 to be overexposed, effectively solving the problem of camera overexposure caused by the strong light of the burning flame.
[0022] Please see Figures 4-6The surface cleaning mechanism 9 includes guide rails 92 symmetrically fixed between mounting frames 71. Each guide rail 92 includes a sweeping section 921 parallel to the outer protective layer 73 and a tilting section 922 at a certain angle to the outer protective layer 73. The slides on the sweeping section 921 and the tilting section 922 are interconnected, and a cleaning frame 91 is slidably connected within the slides of the sweeping section 921 and the tilting section 922. A flexible scraping surface on one side of the cleaning frame 91 adheres to the mounting frame 72 and the outer protective layer 73. When the cleaning frame 91 slides within the slide of the sweeping section 921, it can clean the surface of the outer protective layer 73, removing impurities splashed onto the outer protective layer 73. A connecting rod is rotatably connected to the top of the cleaning frame 91. The connecting block 93 is equipped with a slag removal mechanism 94. The slag removal mechanism 94 includes a support frame 941 fixed on one of the flip sections 922. A connecting shaft 942 is rotatably connected to the support frame 941. An upper gear 943 is fixedly sleeved on the top end of the connecting shaft 942, and elastic plates 945 are evenly arranged on the bottom end of the connecting shaft 942. A striking strip 944 is fixed to one end of the elastic plate 945. An upper rack 946 is slidably connected to a protrusion on one side of the connecting block 93. When the upper rack 946 moves to the position of the upper gear 943, it can drive the upper gear 943 and the connecting shaft 942 to rotate through meshing. One end of the upper rack 946 is fixed on the drive mechanism 95.
[0023] Please see Figure 5 and Figure 6The drive mechanism 95 includes a drive frame 951 fixed to one end of the upper rack 946. The drive frame 951 is slidably connected to the connecting block 93 via a guide rod. A support spring 952 is provided between the drive frame 951 and the connecting block 93, and the support spring 952 is sleeved on the guide rod. The drive frame 951 is slidably connected to the guide rod 953, and both ends of the guide rod 953 are fixed to two mounting brackets 71. A lower rack 954 is fixed to the bottom end of the drive frame 951, and the output end of the drive electric cylinder 955 is fixedly connected to the drive frame 951. The drive electric cylinder 955 is fixedly connected in the heat insulation shell 956, and the heat insulation shell 956 is fixed to the inner wall of the heat insulation layer 2. It can isolate the heat generated during combustion detection, preventing the drive cylinder 955 from overheating and being damaged. In the initial state, the cleaning frame 91 is located in the center of the mounting frame 72 and does not obstruct the area in front of the lens of the flame detection camera 6. When cleaning the outer protective layer 73, the output end of the drive cylinder 955 extends, driving the drive frame 951 to slide along the guide rod 953. The drive frame 951 synchronously pulls the upper rack 946 to move in the same direction. The drive frame 951 pushes the connecting block 93 and the cleaning frame 91 along the cleaning section 921 through the support spring 952, and gradually approaches the flipping section 922. When the cleaning frame 91 slides in the cleaning section 921, it will clean the surface of the outer protective layer 73 until it is completely cleaned. The cleaning section 921 slides into the flipping section 922. Then, the cleaning frame 91, limited by the flipping section 922 and the connecting block 93, flips. During the gradual flipping process along the flipping section 922, it abuts against the striking bar 944 until the cleaning frame 91 moves to the end of the flipping section 922. Afterward, the movement of the cleaning frame 91 is blocked by the flipping section 922. The drive frame 951 compresses the support spring 952 and approaches the connecting block 93. Simultaneously, the upper rack 946 meshes with the upper gear 943. At this time, the continuous movement of the drive frame 951 drives the upper gear 943 to rotate through the meshing action, thereby driving the connecting shaft 942 to rotate synchronously. When the connecting shaft 942 rotates, the elastic plate 945 at its bottom edge moves accordingly. The shaft rotates and generates centrifugal force. The elastic plate 945 drives the striking bar 944 to make a circular motion. The striking bar 944 repeatedly strikes the flexible cleaning surface of the cleaning frame 91, shaking off the impurities adhering to the flexible cleaning surface during the cleaning process, thus achieving slag removal and cleaning. After cleaning is completed, the drive cylinder 955 drives the whole system to reset. During the reset process, the elastic plate 945 drives the striking bar 944 to make a reverse circular motion to vibrate again. Then, the upper rack 946 disengages from the upper gear 943, the support spring 952 releases elastic potential energy, and after stretching, it pulls the cleaning frame 91 from the flipping section 922 into the cleaning section 921 through elastic force. After cleaning the outer protective layer 73 again, it returns to the center position of the mounting frame 72.
[0024] Please see Figures 5-6The anti-exposure mechanism 8 includes a rotating column 81 mounted on the mounting frame 72, and the rotating column 81 is rotatably connected to the mounting frame 72 via a damping bearing. A filter holder 82 is fixedly mounted on the rotating column 81, and filters to prevent overexposure of the flame detection camera 6 are fixedly mounted at both ends of the filter holder 82. A drive gear 83 is fixedly mounted on the rotating column 81, and a lower rack 954 can mesh with the drive gear 83. When the filter needs to be replaced, the drive cylinder 955 retracts, pulling the drive frame 951 away from the outer protective layer 73. Then, the lower rack 954 at the bottom of the drive frame 951 meshes with the drive gear 83, and the movement of the lower rack 954 pulls the rotating column 81 to overcome the friction with the mounting frame 72 and rotate 180 degrees, thereby realizing the replacement of the filter.
[0025] It should be noted that, when using this comprehensive burner performance testing device, the burner to be tested is first fixed on the fixture, and the fixture is installed at the bottom of the inner side of the insulation layer 2. The burner is connected to the gas supply pipe 5, which delivers combustion-supporting gas. Then, the flip door 10 is closed, and the operator sets the testing parameters through the control module in the control box 3, including the mixing ratio of combustion-supporting gas and oxygen, the testing time, the temperature warning threshold, and the gas concentration warning range, thus completing the pre-test preparation work. After preparation, the control module starts the combustion gas supply equipment, which mixes the combustion gas and oxygen in a preset ratio. The mixed combustion gas is then stably delivered to the burner through the gas supply pipe 5. Simultaneously, the control module triggers the burner to ignite, and the burner begins normal combustion. During combustion, the temperature sensor inside the insulation layer 2 monitors the temperature changes in the combustion zone in real time and transmits the temperature data synchronously to the control module. The gas sensor near the gas outlet channel 4 synchronously collects the concentration data of the combustion products and feeds it back to the control module in real time, facilitating the monitoring of combustion completeness and pollutant emissions. The flame detection camera 6 is activated simultaneously, observing the combustion flame through the outer protective layer 73. The filter in the anti-exposure mechanism 8 reduces light, preventing the high brightness at the center of the flame from causing overexposure of the camera. This ensures that the flame detection camera 6 can clearly capture the shape, pulsation frequency, and other dynamic states of the flame. The collected flame image data is transmitted to the control module for storage in real time. During the inspection, if the surface of the outer protective layer 73 is affected by sparks, smoke, and dust from combustion, causing a decrease in the imaging clarity of the flame detection camera 6, the control module can trigger the surface cleaning mechanism 9 to operate. The output end of the drive cylinder 955 extends, driving the drive frame 951 to slide along the guide rod 953. The drive frame 951 simultaneously pulls the upper rack 946 to move in the same direction. At the same time, the drive frame 951 pushes the connecting block 93 and the cleaning frame 91 along the cleaning section 921 of the guide rail 92 through the support spring 952. The flexible scraping surface on one side of the cleaning frame 91 closely adheres to the surface of the outer protective layer 73 and the mounting frame 72, sweeping away the attached impurities during the sliding process. As the drive frame 951 continues to move, the cleaning frame 91 slides from the cleaning section 921 into the flipping section 922, where it is limited by the flipping section 922 and the connecting block 93. Under the action, the cleaning frame 91 gradually flips, and during the process of flipping along the flipping section 922, it will abut against the striking bar 944 until the cleaning frame 91 moves to the end of the flipping section 922. At this time, the cleaning frame 91 is blocked by the flipping section 922 and cannot continue to move. The drive frame 951 continues to move and compresses the support spring 952, while driving the upper rack 946 to mesh with the upper gear 943 of the slag removal mechanism 94. The drive frame 951 continues to move, and through the meshing of the rack and gear, it drives the upper gear 943 to rotate, which in turn drives the connecting shaft 942 to rotate synchronously. The elastic plate 945 at the bottom of the connecting shaft 942 rotates with the shaft, driving the striking bar 944 to make a circular motion. The striking bar 944 repeatedly strikes the flexible cleaning surface of the cleaning frame 91, shaking off the stubborn impurities that adhere to the cleaning surface during the cleaning process, thus achieving slag removal and cleaning. After slag removal is completed, the output end of the drive cylinder 955 retracts, causing the drive frame 951 to slide in the opposite direction along the guide rod 953, entering the reset process: During the reset process, the upper rack 946 continues to mesh with the upper gear 943, causing the connecting shaft 942 to rotate in the opposite direction, and the elastic plate 945 causes the striking strip 944 to make a circular motion in the opposite direction, vibrating the flexible cleaning surface again to ensure that the impurities are completely removed; then the drive frame 951 continues to move in the opposite direction, the upper rack 946 disengages from the upper gear 943, the support spring 952 releases its elastic potential energy, and under the stretching action, it pulls the cleaning frame 91 from the flipping section 922 into the cleaning section 921 through the connecting block 93. During the sliding process, the flexible cleaning surface once again adheres to the surface of the outer protective layer 73 for secondary cleaning to ensure that there are no residual impurities on the surface of the outer protective layer 73; finally, the cleaning frame 91 slides along the cleaning section 921 to the initial center position of the mounting frame 72, without blocking the area in front of the lens of the flame detection camera 6, the surface cleaning mechanism 9 completes the reset, and the flame detection camera 6 resumes normal acquisition work; During the detection process, if it is necessary to switch the detection scene according to the flame intensity, the control module controls the drive cylinder 955 to retract, pulling the drive frame 951 away from the outer protective layer 73. The lower rack 954 at the bottom of the drive frame 951 moves with the drive frame 951 and meshes with the drive gear 83 of the anti-exposure mechanism 8. The drive frame 951 continues to move in the opposite direction. Through the meshing of the lower rack 954 and the drive gear 83, the rotating column 81 is pulled to overcome the friction of the contact surface with the mounting frame 72 and rotate 180 degrees. The rotating column 81 drives the filter holder 82 to rotate synchronously, realizing the rapid replacement of the filters at both ends of the filter holder 82. After the replacement is completed, the rotating column 81 remains stable under the action of the damping bearing to ensure the stability of the filter position. The flame detection camera 6 continues to perform detection through the replaced filter to adapt to different detection needs. During the detection process, the control module receives data from the temperature sensor, gas sensor, and flame detection camera 6 in real time, stores, analyzes, and processes the data. If the temperature exceeds the preset warning threshold or the concentration of combustion products exceeds the standard, the control module will automatically issue a warning signal and can shut down the burner and stop the supply of combustion gas according to the preset program to avoid equipment damage or detection accidents. Operators can also observe the combustion status of the burner from the outside through the observation window 11 on the flip door 10 to help judge the detection situation.
[0026] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
