Description

Technical Field

[0001] This utility model relates to the field of finned tube polishing technology, and in particular to a finned tube polishing device. Background Technology

[0002] Finned tubes are a type of high-efficiency heat exchange tube designed to enhance heat transfer efficiency. The core consists of a base tube as the basic carrier and fins that are welded, rolled, or fitted onto the outer surface of the base tube. A finned tube polishing device is an automated or semi-automated mechanical device that performs specialized polishing treatment on the surface and fin gaps of finned tubes (high-efficiency heat exchange tubes with radial annular or spiral fins).

[0003] After polishing, traditional finned tube polishing devices leave polishing dust on the surface of the tube. Some fine dust particles adhere tightly to the smooth surface of the tube, requiring workers to use tools such as lint-free cloths to clean the surface, which is inefficient. To address this, we propose a finned tube polishing device. Utility Model Content

[0004] The purpose of this invention is to provide a finned tube polishing device to solve the problem mentioned in the background art that after the polishing operation is completed, polishing dust will remain on the surface of the finned tube. Some fine dust will adhere tightly to the smooth surface of the tube by adsorption. When cleaning, workers need to use tools such as lint-free cloths to clean the surface of the tube, which is inefficient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a finned tube polishing device, comprising a cleaning mechanism disposed on the upper rear surface of the operating table, a limiting mechanism disposed in the middle of the upper surface of the operating table, the cleaning mechanism comprising a rectangular frame, a plurality of sliding rods slidably connected to the upper end of the rectangular frame, a plurality of compression springs fixedly connected to the inner wall of the rectangular frame, a first semi-ring plate fixedly connected to the telescopic end of the compression spring, the other end of the sliding rods fixedly connected to the outer wall of the first semi-ring plate, a brush fixedly connected to the inner wall of the first semi-ring plate, a blower fixedly connected to the inner wall of the rectangular frame, a filter fixedly connected to the front side of the blower, and elastic sealing rings fixedly connected to both the front and rear sides of the rectangular frame.

[0006] As a preferred embodiment, a motor is fixedly connected to the lower front surface of the operating table, and the motor is connected to a conveying pipe via a belt drive. The front and rear sides of the conveying pipe are fixedly connected to the upper surface of the operating table via connecting blocks. The conveying pipe is rotatably connected inside the connecting blocks. A polishing mechanism is provided on the upper surface of the operating table. The polishing mechanism is located on the rear left side of the conveying pipe, and the cleaning mechanism is located on the rear side of the conveying pipe.

[0007] As a preferred embodiment, the lower end of the slide rod extends to the outer side of the inner wall of the rectangular frame, a limit block is fixedly connected to the sliding end of the slide rod, and the compression spring is sleeved on the outer wall of the slide rod.

[0008] As a preferred embodiment, a receiving box is slidably connected to the lower end of the rectangular frame, and the receiving box is located directly below the brush.

[0009] As a preferred embodiment, the limiting mechanism includes an L-shaped support frame, the lower surface of which is fixedly connected to the upper surface of the operating table, and an electric telescopic rod is fixedly connected to the lower surface of the horizontal section of the L-shaped support frame.

[0010] As a preferred embodiment, the telescopic end of the electric telescopic rod is fixedly connected to a second semi-ring plate, and a rubber pad is fixedly connected to the inner wall of the second semi-ring plate, with the rubber pad located directly above the conveying pipe.

[0011] The technical effects and advantages of this utility model are as follows: Through the cleaning mechanism, one end of the slide rod slides inside the rectangular frame, while the other end is fixedly connected to the first semi-ring plate. The compression spring sleeved on the outer wall of the first semi-ring plate provides an inward elastic preload, which makes the brush on the inner wall of the first semi-ring plate closely adhere to the surface of the finned tube. During operation, the uniform rotation of the finned tube and the elastic contact of the brush form an all-round relative friction, further cleaning the floating dust on the surface of the tube. The sealing rings at the front and rear ends of the rectangular frame can effectively prevent the dust raised by the brush during the cleaning process from spreading outward from the discharge port. The blower inside the rectangular frame blows the dust that is swept off by the brush to the collection box at the bottom of the device, further improving the cleaning efficiency. With the setting of the limiting mechanism, the L-shaped support frame is fixed above the feed end of the conveying pipe. The electric telescopic rod fixedly connected to its lower surface is fixedly connected to the second half-ring plate. In the initial state, the electric telescopic rod drives the second half-ring plate to rise to a high position, which makes it easy for the operator to put the finned tube into the conveying pipe. After the finned tube is placed in place, the electric telescopic rod drives the second half-ring plate to descend, so that it is aligned with the port of the conveying pipe to form a coaxial limiting. The rubber pad attached to the inner wall of the second half-ring plate has both elasticity and wear resistance. It can limit the radial displacement of the finned tube during conveying through flexible contact, and avoid direct contact between the hard structure and the finned tube during the limiting process, effectively preventing the tube body from being scratched.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1 - Appendix Figure 4 The finned tube polishing device includes an operating table 1. A cleaning mechanism 5 is provided on the upper rear surface of the operating table 1. A limit mechanism 6 is provided in the middle of the upper surface of the operating table 1. The cleaning mechanism 5 includes a rectangular frame 501. Multiple sets of slide rods 502 are slidably connected to the upper end of the rectangular frame 501. Multiple sets of compression springs 503 are fixedly connected to the inner wall of the rectangular frame 501. A first semi-ring plate 504 is fixedly connected to the telescopic end of the compression spring 503. The other end of the slide rod 502 is fixedly connected to the outer wall of the first semi-ring plate 504. A brush 505 is fixedly connected to the inner wall of the first semi-ring plate 504. A blower 506 is fixedly connected to the inner wall of the rectangular frame 501. Elastic sealing rings 507 are fixedly connected to both the front and rear sides of the rectangular frame 501.

[0016] The interior of the rectangular frame 501 is a hollow cavity. Multiple sets of sliding holes are formed inside the upper end of the rectangular frame 501. Multiple sets of sliding rods 502 are slidably connected within these sliding holes with clearance fit. A compression spring 503 is sleeved on the outside of the sliding rod 502, and its extension and retraction direction is synchronized with the sliding direction of the sliding rod 502. Under the elastic preload of the compression spring 503, the first semi-ring plate 504 drives the brush 505 to always remain in contact with the surface of the finned tube. The bristles of the brush 505 are longer than the finned tube, ensuring that the bristles can penetrate deep into the fin gaps and fit tightly against the tube surface. The airflow generated by the fan 506 blows the impurities swept off by the brush 505 into the collection box 508. The elastic sealing ring 507 is made of fluororubber. Under the compression of the tube body, the elastic sealing ring 507 undergoes elastic deformation to form a tight sealing structure, effectively preventing impurities from overflowing and polluting the working environment. The rectangular frame 501 has outlet ports on both sides of the elastic sealing ring 507, which facilitates the cleaning of the finned tube. The elastic sealing ring 507 is made of elastic material and can be adjusted according to the diameter of the finned tube to facilitate the fit of the finned tube.

[0017] A motor 2 is fixedly connected to the lower front surface of the operating table 1. The motor 2 is connected to a conveying pipe 3 via a belt drive. The front and rear sides of the conveying pipe 3 are fixedly connected to the upper surface of the operating table 1 via connecting blocks. The conveying pipe 3 is rotatably connected inside the connecting blocks. A polishing mechanism 4 is provided on the upper surface of the operating table 1. The polishing mechanism 4 is located on the rear left side of the conveying pipe 3. A cleaning mechanism 5 is located on the rear side of the conveying pipe 3.

[0018] The lower front surface of the operating table 1 is fixedly connected to the motor 2 by bolts. The output shaft end of the motor 2 is fixedly fitted with a drive pulley by a flat key. The drive pulley is connected to the driven pulley at the front end of the conveying pipe 3 by a transmission belt to achieve stable power transmission. The front and rear sides of the conveying pipe 3 are fixed to the upper surface of the operating table 1 by symmetrically arranged connecting blocks. The connecting blocks are fitted with deep groove ball bearings. The end of the conveying pipe 3 is connected to the inner ring of the bearing by an interference fit, so that the conveying pipe 3 can rotate smoothly around its own axis within the connecting block. This structure is a mature existing product for achieving smooth conveying of finned tubes. The upper surface of the operating table 1 is provided with a polishing mechanism 4 at the rear left end of the conveying pipe 3. The polishing mechanism 4 includes a polishing machine and a polishing roller, which is used to polish the finned tubes. This is a mature existing technology.

[0019] The lower end of the slide rod 502 extends to the outer side of the inner wall of the rectangular frame 501. A limit block is fixedly connected to one end of the slide rod 502, and a compression spring 503 is sleeved on the outer wall of the slide rod 502.

[0020] The number of slide rods 502 and compression springs 503 is the same. One end of the slide rod 502 located inside the rectangular frame 501 (i.e., the sliding end) is fixedly connected to a limit block by welding. The limit block can effectively limit the sliding stroke of the slide rod 502 and prevent the slide rod 502 from disengaging from the sliding hole. The compression spring 503 is coaxially sleeved on the outer wall of the slide rod 502. One end of the compression spring 503 abuts against the spring seat on the inner wall of the rectangular frame 501, and the other end is connected to the second half-ring plate 603. This can ensure that the extension and contraction direction of the compression spring 503 is consistent with the sliding direction of the slide rod 502, and avoid the instability of the elastic preload caused by spring offset.

[0021] A receiving box 508 is slidably connected to the lower end of the rectangular frame 501, and the receiving box 508 is located directly below the brush 505.

[0022] The receiving box 508 has an open top structure, and its size is the same as the cleaning opening at the bottom of the rectangular frame 501, ensuring that it can catch the dust falling directly below the brush 505.

[0023] Specifically, through the cleaning mechanism 5, one end of the slide rod 502 slides inside the rectangular frame 501, and the other end is fixedly connected to the first semi-ring plate 504. The compression spring 503 sleeved on the outer wall of the first semi-ring plate 504 provides an inward elastic preload, so that the brush 505 on the inner wall of the first semi-ring plate 504 is tightly attached to the surface of the finned tube. During operation, the rotation of the finned tube and the elastic contact of the brush 505 form relative friction, further cleaning the floating dust on the surface of the tube. The elastic sealing rings 507 at the front and rear ends of the rectangular frame 501 effectively prevent the dust raised by the brush 505 during the cleaning process from spreading outward from the discharge port. The blower 506 inside the rectangular frame 501 blows the dust cleaned off by the brush 505 in a directional direction to the collection box 508 at the lower end of the device, improving the cleaning efficiency.

[0024] Please see the appendix Figure 5 The limiting mechanism 6 includes an L-shaped support frame 601, the lower surface of which is fixedly connected to the upper surface of the operating table 1, and an electric telescopic rod 602 is fixedly connected to the lower surface of the horizontal section of the L-shaped support frame 601.

[0025] The electric telescopic rod 602 connected to its horizontal section can drive the second semi-ring plate 603 to rise and fall, making it easier to place the finned tube above the conveying pipe 3.

[0026] The telescopic end of the electric telescopic rod 602 is fixedly connected to a second semi-ring plate 603, and a rubber pad 604 is fixedly connected to the inner wall of the second semi-ring plate 603. The rubber pad 604 is located directly above the conveying pipe 3.

[0027] When the electric telescopic rod 602 drives the second semi-ring plate 603 to descend, the rubber pad 604 first contacts the surface of the finned tube, and then conforms to the tube body and fin contour of the finned tube through its own deformation, thereby achieving flexible positioning.

[0028] Specifically, through the setting limiting mechanism 6, the L-shaped support frame 601 is fixed above the feed end of the conveying pipe 3. The electric telescopic rod 602 fixedly connected to its lower surface is fixedly connected to the second semi-ring plate 603. In the initial state, the electric telescopic rod 602 drives the second semi-ring plate 603 to rise to a high position, which makes it easy for the operator to put the finned tube into the conveying pipe 3. After the finned tube is placed in place, the electric telescopic rod 602 drives the second semi-ring plate 603 to descend, so that it is aligned with the port of the conveying pipe 3 to form a coaxial limiting. The rubber pad 604 attached to the inner wall of the second semi-ring plate 603 has both elasticity and wear resistance. It not only limits the radial displacement of the finned tube during conveying through flexible contact, but also avoids direct contact between the hard structure and the finned tube during the limiting process, thus preventing the tube body from being scratched.

[0029] Working principle of this utility model: This utility model is a finned tube polishing device. First, before starting the equipment, the electric telescopic rod 602 below the L-shaped support frame 601 drives the second semi-ring plate 603 to a high position, opening the feed end of the conveying pipe 3, making it easy for the operator to place the finned tube to be processed stably into the conveying pipe 3. Then, after the finned tube is placed in the conveying pipe 3, the electric telescopic rod 602 drives the second semi-ring plate 603 to descend vertically until the rubber pad 604 on the inner wall of the second semi-ring plate 603 is tightly attached to the upper surface of the finned tube. The rubber pad 604 passes through... The self-deformation adapts to the fin contour, avoiding rigid contact that could scratch the tube body. The motor 2 on the lower front surface of the operating table 1 starts, driving the conveyor pipe 3 to rotate smoothly around the deep groove ball bearing inside the connecting block via a drive pulley. The conveyor pipe 3, through friction, drives the internal fin tube to rotate synchronously and is conveyed towards the polishing mechanism 4. Simultaneously, the polishing mechanism 4 starts, driving the polishing wheels in two sets of arc-shaped polishing seats to rotate at high speed via a synchronous pulley. With the rotation and axial conveying of the fin tube, the polishing wheels perform all-around friction polishing on its surface, removing oxide scale, burrs, and processing marks. The polished finned tube continues to be conveyed backward by the conveying pipe 3 and enters the internal cleaning channel of the rectangular frame 501 of the cleaning mechanism 5. At this time, the finned tube remains in a rotating state. Under the elastic preload of the compression spring 503, the slide rod 502 at the upper end of the rectangular frame 501 drives the first semi-ring plate 504 to always be in contact with the surface of the finned tube. The slide rod 502 flexibly extends and retracts along the sliding hole of the rectangular frame 501 to adapt to the undulating contour of the fins, ensuring that the brush 505 on the inner wall of the first semi-ring plate 504 can both penetrate into the gaps between the fins and make close contact with the surface of the tube, cleaning the residue through relative friction. While the polishing dust remains, the blower 506 on the inner wall of the rectangular frame 501 starts, generating a directional airflow directed towards the receiving box 508. This blows the dust swept down by the brush 505 towards the lower end of the rectangular frame 501. The elastic sealing rings 507 on the front and rear sides of the rectangular frame 501 tightly adhere to the outer wall of the finned tube, forming a sealing barrier to prevent dust from overflowing from both ends of the channel. Finally, the dust falls into the receiving box 508 located directly below the brush 505 under the guidance of the airflow, achieving centralized collection. Operators can periodically remove the receiving box 508 for cleaning, completing one processing cycle.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
