Description

Technical Field

[0001] This application relates to the field of burner wind speed measurement technology, and more specifically, to a burner air volume testing device. Background Technology

[0002] Burners are core equipment in industrial and civil fields that convert fuel into heat energy. Their core function is to ensure stable ignition and efficient combustion of fuel in the furnace by precisely controlling the mixing ratio of fuel and air, injection speed and turbulence. Burner airflow testing is a core link to ensure efficient, safe and environmentally friendly operation of the combustion process. Abnormal airflow may lead to unstable combustion of the burner, or even cause safety accidents such as backfire and deflagration. Regular airflow testing can detect hidden dangers in time and avoid equipment damage or personal injury.

[0003] During the burner airflow test, a certain amount of dust is generated during the combustion process of the burner. The dust may adhere to the probe or sensor of the anemometer, changing its heat dissipation conditions and causing inaccurate temperature changes in the measurement. This, in turn, causes the calculated wind speed value to deviate. Therefore, after the wind speed measurement is completed, it is necessary to clean the dust on the anemometer in time.

[0004] The common cleaning method is to wipe the anemometer probe and housing with a clean, soft cloth to remove surface dust and dirt. However, when the dust concentration is too high and wiping alone is insufficient to clean the dust completely, the anemometer needs to be disassembled for cleaning or replacement. Since the installation of anemometers often requires complex fixing devices and cumbersome operating procedures, such as tightening with multiple screws, the complex installation structure makes the disassembly process very difficult when the anemometer needs to be disassembled for cleaning or maintenance. This not only increases the workload of the operator but also easily leads to damage to the anemometer during disassembly, which can cause unnecessary losses. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a burner air volume testing device, which aims to improve the problem that the complex installation structure makes the disassembly process very difficult, increases the workload of operators, and is also prone to damage to the anemometer during the disassembly process, which can easily cause unnecessary losses.

[0006] This application provides a burner airflow testing device, including a measuring structure and an adjusting structure. The measuring structure includes a base plate, a mounting base, an anemometer body, and a clamping assembly. The mounting base is located at the rear end of the top of the base plate, the anemometer body is located at the top of the mounting base, and the clamping assembly is disposed in the inner cavity of the mounting base. The clamping assembly includes two clamping bars, which are respectively attached to both sides of the anemometer body. The adjusting structure includes a position adjusting assembly and a height adjusting assembly. The position adjusting assembly is located at the rear end of the top of the base plate, the height adjusting assembly is located above the position adjusting assembly, and the anemometer body is located above the height adjusting assembly.

[0007] In one specific implementation, the measuring structure further includes a buffer pad fixedly connected to the top of the base plate, the buffer pad being made of rubber.

[0008] In the above process, the top of the base plate is used to place the burner to be tested, and the buffer pad supports the burner while also playing a role in shock absorption.

[0009] In one specific implementation, the clamping assembly further includes a threaded rod, a threaded sleeve, an adjusting plate, and a receiving groove. The threaded rod is movably connected to the inner cavity of the mounting base via a bearing. The threaded sleeve is threadedly connected to the surface of the threaded rod. The adjusting plate is movably connected to both sides of the threaded sleeve via a rotating shaft. The receiving groove is formed on both sides of the inner cavity of the mounting base. One side of the adjusting plate extends into the inner cavity of the receiving groove and is movably connected to its inner cavity.

[0010] In the above process, the threaded rod can adjust the position of the threaded sleeve by rotating, so that it can move forward or backward on the surface of the threaded rod. Since the two adjusting plates are movably connected to both sides of the threaded sleeve through rotating shafts, when the threaded sleeve moves back and forth, it can cooperate with the support block and connecting column to adjust the position of the two clamping bars, so that they can clamp or release the anemometer body.

[0011] In one specific implementation, the clamping assembly further includes a support block, a guide groove, and a connecting post. The support block is fixedly connected to the end of the adjusting plate away from the threaded sleeve. The guide groove is opened on both sides of the top of the mounting base. The connecting post is movably connected to the inner cavity of the guide groove, and the top of the connecting post is fixedly connected to the bottom of the clamping bar, and the bottom is movably connected to the top of the support block through a bearing.

[0012] In the above implementation process, the guide groove is used to accommodate the connecting column and provide it with space to move. It can also guide the connecting column to ensure that it moves along a preset trajectory. The connecting column is used to connect the support block and the clamping bar, so that the clamping bar can move with the adjustment plate.

[0013] In one specific embodiment, the clamping assembly further includes a rotating handle located on the back of the mounting base, and the rear end of the threaded rod extends through to the back of the mounting base and is fixedly connected to the rotating handle.

[0014] In the above process, the rotating handle facilitates the rotation of the threaded rod from the outside of the mounting base, thereby facilitating the installation or removal of the anemometer body.

[0015] In one specific implementation, the position adjustment assembly includes a support plate, a threaded column, and a threaded seat. The support plate is fixedly connected to the front and rear ends of the top of the base plate. The threaded column is movably connected between the two support plates via a bearing. The threaded seat is located on the surface of the threaded column and is threadedly connected to its surface.

[0016] In the above implementation process, the support plate supports the threaded column, servo motor and limit column, and the threaded seat is used to support and fix the fixed frame. Since the threaded seat is threadedly connected to the surface of the threaded column, when the threaded column rotates, it can drive the threaded seat to move forward or backward on its surface, so as to adjust the position of the fixed frame, the mounting base and the anemometer body, thereby adjusting the distance between the anemometer body and the burner.

[0017] In one specific implementation, the position adjustment assembly further includes a servo motor, which is fixedly connected to the back of the rear support plate by bolts, and its output shaft passes through the rear support plate and is drivenly connected to the rear end of the threaded column.

[0018] In the above implementation process, the servo motor is used to provide power for the rotation of the threaded column.

[0019] In one specific implementation, the position adjustment assembly further includes a limiting hole and a limiting post. The limiting hole is opened on both sides of the inner cavity of the threaded seat, and the limiting post is slidably connected to the inner cavity of the limiting hole. The front end and the rear end of the limiting post are respectively fixedly connected to two support plates.

[0020] In the above process, the limiting hole and the limiting post work together to limit the threaded seat and prevent it from tilting during its forward and backward movement.

[0021] In one specific implementation, the height adjustment assembly includes a mounting bracket and an electric actuator. The mounting bracket is fixedly connected to the top of the threaded seat, and the electric actuator is fixedly connected to the inner cavity of the mounting bracket. The output end of the electric actuator is fixedly connected to the bottom of the mounting base.

[0022] In the above implementation process, the mounting bracket is used to fix the electric push rod. At the same time, the back of the mounting bracket is designed with a hollow back to facilitate heat dissipation of the electric push rod during use. The electric push rod is used to adjust the height of the mounting base, thereby adjusting the height of the anemometer body. By adjusting the position and height of the anemometer body, the anemometer body can be used to measure in areas with relatively low dust concentration, thereby further reducing the impact of dust on the normal use of the anemometer body.

[0023] In one specific implementation, the height adjustment assembly further includes a positioning groove and a positioning post. The positioning groove is formed at the top of the fixing frame, and the positioning post is fixedly connected to the bottom of the mounting base. The bottom of the positioning post extends into the inner cavity of the positioning groove and is slidably connected to its inner cavity.

[0024] In the above process, the positioning groove and positioning column work together to limit the mounting base and ensure that it remains stable during the lifting and lowering process.

[0025] Compared with the prior art, the beneficial effects of this application are as follows: the base plate is used to support the burner to be measured, and the anemometer body is used to measure the air volume of the burner. By using the clamping assembly, the anemometer body can be quickly installed or disassembled. This not only makes installation and disassembly convenient but also reduces the workload of operators, prevents damage to the anemometer body due to improper operation, and avoids unnecessary losses. At the same time, the position adjustment assembly can adjust the distance between the anemometer body and the burner, and the height adjustment assembly can adjust the operating height of the anemometer body. By adjusting the distance between the anemometer body and the burner and the operating height of the anemometer body, the anemometer body can be used for measurement in areas with relatively low dust concentration, thereby further reducing the impact of dust on the normal use of the anemometer body.

The anemometer body 130 is located above the height adjustment component 220.

[0040] In a specific configuration, the measuring structure 10 also includes a buffer pad 150 fixedly connected to the top of the base plate 110. The buffer pad 150 is made of rubber. The top of the base plate 110 is used to place the burner to be tested. The buffer pad 150 supports the burner and also plays a role in shock absorption.

[0041] In a specific configuration, the clamping assembly 140 also includes a threaded rod 1402, a threaded sleeve 1403, an adjusting plate 1404, and a receiving groove 1405. The threaded rod 1402 is movably connected to the inner cavity of the mounting base 120 via bearings. The threaded sleeve 1403 is threadedly connected to the surface of the threaded rod 1402. The adjusting plate 1404 is movably connected to both sides of the threaded sleeve 1403 via a rotating shaft. The receiving groove 1405 is formed on both sides of the inner cavity of the mounting base 120, and one side of the adjusting plate 1404 extends into the receiving groove 1405. The threaded rod 1402 is movably connected to the inner cavity of the threaded sleeve 1403 by rotation, so that the threaded sleeve 1403 can move forward or backward on the surface of the threaded rod 1402. Since the two adjusting plates 1404 are movably connected to the two sides of the threaded sleeve 1403 through rotating shafts, when the threaded sleeve 1403 moves back and forth, it can cooperate with the support block 1406 and the connecting column 1408 to adjust the position of the two clamping bars 1401, so that they clamp or release the anemometer body 130.

[0042] In a specific configuration, the clamping assembly 140 also includes a support block 1406, a guide groove 1407, and a connecting post 1408.

The guide groove 1407 is used to accommodate the connecting post 1408 and provide it with space for movement. It can also guide the connecting post 1408 to ensure that it moves along a preset trajectory. The connecting post 1408 is used to connect the support block 1406 and the clamping bar 1401, so that the clamping bar 1401 can move with the adjusting plate 1404.

[0043] In a specific configuration, the clamping assembly 140 also includes a rotating handle 1409. The rotating handle 1409 is located on the back of the mounting base 120, and the rear end of the threaded rod 1402 extends through to the back of the mounting base 120 and is fixedly connected to the rotating handle 1409. The rotating handle 1409 facilitates the rotation of the threaded rod 1402 from the outside of the mounting base 120, thereby facilitating the installation or removal of the anemometer body 130.

[0044] In a specific configuration, the position adjustment assembly 210 includes a support plate 2101, a threaded post 2102, and a threaded seat 2104. The support plate 2101 is fixedly connected to the front and rear ends of the top of the base plate 110. The threaded post 2102 is movably connected between the two support plates 2101 via bearings. The threaded seat 2104 is located on the surface of the threaded post 2102 and is threadedly connected to its surface. The support plate 2101 provides support for the threaded post 2102, the servo motor 2103, and the limit post 2106. The threaded seat 2104 is used to support and fix the fixing frame 2201. Since the threaded seat 2104 is threadedly connected to the surface of the threaded post 2102, when the threaded post 2102 rotates, it can drive the threaded seat 2104 to move forward or backward on its surface, thereby adjusting the position of the fixing frame 2201, the mounting base 120, and the anemometer body 130, and thus adjusting the distance between the anemometer body 130 and the burner.

[0045] In a specific configuration, the position adjustment component 210 also includes a servo motor 2103. The servo motor 2103 is fixedly connected to the back of the rear support plate 2101 by bolts, and its output shaft passes through the rear support plate 2101 and is connected to the rear end of the threaded column 2102. The servo motor 2103 is used to provide power for the rotation of the threaded column 2102.

[0046] In a specific configuration, the position adjustment component 210 also includes a limiting hole 2105 and a limiting post 2106. The limiting hole 2105 is opened on both sides of the inner cavity of the threaded seat 2104, and the limiting post 2106 is slidably connected to the inner cavity of the limiting hole 2105. The front end and the rear end of the limiting post 2106 are fixedly connected to two support plates 2101 respectively. The limiting hole 2105 and the limiting post 2106 cooperate to limit the threaded seat 2104 and prevent it from tilting during its forward and backward movement.

[0047] In specific settings, the height adjustment component 220 includes a fixed frame 2201 and an electric push rod 2202. The fixed frame 2201 is fixedly connected to the top of the threaded seat 2104, and the electric push rod 2202 is fixedly connected to the inner cavity of the fixed frame 2201. The output end of the electric push rod 2202 is fixedly connected to the bottom of the mounting base 120. The fixed frame 2201 is used to fix the electric push rod 2202. At the same time, the back of the fixed frame 2201 is designed with a hollow shape to facilitate heat dissipation of the electric push rod 2202 during use. The electric push rod 2202 is used to adjust the height of the mounting base 120, thereby achieving the purpose of adjusting the height of the anemometer body 130. By adjusting the position and height of the anemometer body 130, the anemometer body 130 can be used to measure in areas with relatively low dust concentration, thereby further reducing the impact of dust on the normal use of the anemometer body 130. The anemometer body 130 can be a Testo 405i intelligent thermal anemometer.

[0048] In a specific configuration, the height adjustment component 220 also includes a positioning groove 2203 and a positioning post 2204. The positioning groove 2203 is located on the top of the fixed frame 2201, and the positioning post 2204 is fixedly connected to the bottom of the mounting base 120. The bottom of the positioning post 2204 extends into the inner cavity of the positioning groove 2203 and is slidably connected to it. The positioning groove 2203 and the positioning post 2204 work together to limit the mounting base 120 and ensure that it remains stable during the lifting process.

[0049] The working principle of this burner airflow testing device is as follows: The burner to be measured is placed above the buffer pad 150. The servo motor 2103 and the electric push rod 2202 are activated via an external controller. The output shaft of the servo motor 2103 drives the threaded column 2102 to rotate. When the threaded column 2102 rotates, it can adjust the front-to-back position of the threaded seat 2104, thereby adjusting the distance between the anemometer body 130 and the burner. When the electric push rod 2202 is running, its output end extends or retracts, adjusting the height of the mounting base 120, thereby adjusting the operating height of the anemometer body 130. By adjusting the distance between the anemometer body 130 and the burner, and the operating height of the anemometer body 130, the anemometer body 130 can be used for measurement in areas with relatively low dust concentrations, further reducing the impact of dust on the normal operation of the anemometer body 130. During the measurement process, the Testo405i intelligent thermal anemometer... Equipped with Bluetooth, it can connect to smartphones or tablets, displaying and recording measurement data in real time through accompanying software, facilitating data analysis and report generation for staff. When excessive dust adheres to the surface of the anemometer body 130, requiring disassembly for cleaning or replacement, first rotate the rotating handle 1409. Rotating the handle 1409 will drive the threaded rod 1402 to rotate. As the threaded rod 1402 rotates, it will drive the threaded sleeve 1403 to move forward on its surface. As the threaded sleeve 1403 moves forward, it will be guided by the guide groove 1407 to remove the two clamping bars 1401 from both sides of the anemometer body 130 and gradually move forward until the clamping effect on the anemometer body 130 is released. After the clamping is released, the anemometer body 130 can be removed. When the anemometer body 130 needs to be reinstalled, place the anemometer body 130 on top of the mounting base 120 and rotate the rotating handle 1409 in the opposite direction.

[0050] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
