[0001] This utility model relates to the field of heat exchanger tube testing technology, specifically to a heat exchanger tube outer diameter testing device. Background Technology

[0002] Silicon carbide heat exchange tubes possess extremely high hardness and strength, enabling them to withstand high-temperature and high-pressure working conditions. They also exhibit excellent oxidation and thermal shock resistance, allowing for stable operation in complex and harsh environments. Their superior thermal conductivity ensures efficient heat transfer, while their smooth surface design minimizes fluid resistance, further optimizing heat exchange performance. They also demonstrate strong resistance to various corrosive media, effectively extending their service life in corrosive environments. Therefore, they are widely used in chemical, metallurgical, power, and environmental protection fields.

[0003] The existing methods for measuring the outer diameter of silicon carbide heat exchange tubes mainly involve manual measurement using tools such as calipers. Due to differences in the operators' measuring techniques, force, and reading habits, the measurement data fluctuates greatly, making it difficult to accurately obtain the true value of the outer diameter of the silicon carbide heat exchange tube. Moreover, the measurement process is cumbersome and time-consuming. When dealing with a large number of silicon carbide heat exchange tubes in mass production, a lot of manpower is required for repetitive and mechanical measurement work, which not only consumes a lot of human resources but also prolongs the production cycle and increases the company's operating costs.

[0009] As a further description of the above technical solution, the inclination angle of the conveying pallet is the same as that of the feeding tray.

[0010] As a further description of the above technical solution, the heat exchange tube is placed parallel to the discharge bracket.

[0011] As a further description of the above technical solution, a sensor is provided on one side edge of the feeding bracket near the lifting bracket, and the sensor is used to sense whether the heat exchange tube has been fed.

[0012] As a further description of the above technical solution, drive cylinders are symmetrically arranged on both sides of the lifting bracket, and the drive cylinders are used to drive the lifting bracket to rise and fall.

[0013] As a further description of the above technical solution, the conveyor belts are arranged in a collinear manner, and the conveyor belts include a first conveyor belt and a second conveyor belt.

[0014] As a further description of the above technical solution, a transmission motor is provided on one end side of the first conveyor belt and the second conveyor belt.

[0016] As a further description of the above technical solution, the diameter measuring instrument is disposed between the first conveyor belt and the second conveyor belt.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention uses sensors and a drive cylinder to transport heat exchange tubes one by one from the feeding tray to the conveyor belt via a conveyor plate. The outer diameter of the heat exchange tubes is automatically detected by a diameter measuring instrument between the conveyor belts, which effectively improves product quality and production efficiency and saves labor costs.

[0019] To more clearly illustrate the structural features and functions of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figure 1As shown, in one embodiment, a heat exchange tube outer diameter detection device includes: a feeding bracket 1 for placing heat exchange tubes, and a lifting bracket 2 is provided on one side of the feeding bracket 1, and a conveying plate 3 is provided on one side of the lifting bracket 2, so that the lifting bracket 2 can transport the heat exchange tubes on the feeding bracket 1 to the conveying plate 3 by raising and lowering.

[0025] It should be explained in detail that multiple sets of heat exchange tubes are placed in parallel on the feeding tray 1; and a sensor 6 is correspondingly installed on the edge of the feeding tray 1 near the lifting tray 2 to sense whether the heat exchange tubes have arrived, and then cooperate with the lifting tray 2 to transport the heat exchange tubes; wherein, drive cylinders 7 are symmetrically arranged on both sides of the lifting tray 2 to drive the lifting tray 2 to rise and fall, so that the heat exchange tubes can roll down through the lifting tray 2 onto the transport pallet 3 and then be transported onto the conveyor belt 4 for outer diameter detection.

[0026] Furthermore, the top end of the feeding tray 1 is inclined downwards, and the top end of the conveying tray 3 is also inclined downwards. Specifically, the inclination angle of the conveying tray 3 and the feeding tray 1 is the same.

[0027] Please continue reading. Figure 1 In this embodiment, multiple sets of conveyor belts 4 are provided on one side of the conveyor pallet 3, and a diameter gauge 5 is also provided between adjacent conveyor belts 4 to detect the outer diameter of the heat exchange tube that the conveyor pallet 3 rolls onto the conveyor belt 4.

[0028] It is understandable that the diameter measuring instrument 5 is a laser diameter measuring instrument or a charge-coupled device (CCD) diameter measuring instrument. The laser diameter measuring instrument calculates the outer diameter of the heat exchange tube by measuring the characteristics of the diffracted or scattered light formed after the laser beam is blocked. The CCCD diameter measuring instrument, on the other hand, uses an optical imaging system to image the contour of the object being measured onto a CCD image sensor, converts the light signal into an electrical signal and performs digital processing to calculate the outer diameter of the heat exchange tube.

[0029] For example, the conveyor belt 4 includes a first conveyor belt 41 and a second conveyor belt 42, which are arranged collinearly, and the diameter gauge 5 is disposed between the first conveyor belt 41 and the second conveyor belt 42. Specifically, a conveyor motor 8 is provided on the side of one end of the first conveyor belt 41 and the second conveyor belt 42 to drive the conveyor belt 4 to circulate and convey the heat exchange tube; correspondingly, a sensor 9 is provided on the top of the other end of the first conveyor belt 41 and the second conveyor belt 42 to detect whether the heat exchange tube on the current conveyor belt has completed the outer diameter detection.

[0030] Understandably, the diameter gauge 5 can be set to detect the outer diameter. When the measured value exceeds the set range, the device will issue an alarm signal to remind the operator that the heat exchange tube is of substandard quality and needs to be removed and placed away.

[0031] Working principle:

[0032] Because the feeding tray 1 is inclined, the heat exchange tubes will roll down the inclined surface to the edge under the action of gravity. When the sensor detects that the heat exchange tubes have arrived, the drive cylinder 7 drives the lifting tray 2 to descend, allowing the heat exchange tubes to roll onto the lifting tray 2. Then, the drive cylinder 7 drives the lifting tray 2 to rise, raising the heat exchange tubes to one side of the conveyor plate 3. Since the conveyor plate 3 is also inclined, the heat exchange tubes will roll down the inclined surface to the edge under the action of gravity, and then roll onto the conveyor belt 4. Subsequently, the first conveyor belt 41 and the second conveyor belt 42 drive the heat exchange tubes through the conveyor motor 8. When the sensor 9 at the end of the first conveyor belt 41 detects the heat exchange tubes, the diameter measuring instrument 5 is activated to detect the outer diameter of the heat exchange tubes. When the sensor 9 at the end of the second conveyor belt 42 detects the heat exchange tubes, the diameter measuring instrument 5 is turned off, ending the detection process. The above actions are repeated until all the heat exchange tubes on the feeding tray 1 have been detected.

[0033] Through the above technical solutions, this application can effectively improve product quality and production efficiency, and save labor costs.

[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
