Description

Technical Field

[0001] This utility model relates to the field of high-efficiency heat exchange tube processing technology, specifically a high-efficiency heat exchange tube inner wall cleaning device. Background Technology

[0002] High-efficiency heat exchange tubes are heat exchange tubes processed with special techniques to enhance heat transfer. These tubes typically have special shapes or structures that differ from traditional bare tubes, aiming to improve heat transfer efficiency. High-efficiency heat exchange tubes have a wide range of applications, especially in industrial fields requiring high-efficiency heat transfer. To avoid wasting thermal energy resources, it is necessary to recover and utilize the waste heat generated during industrial production. Generally, the outlet of the waste gas is connected to the heat exchange tube for heat recovery. However, due to the high impurity content in the waste gas, the inner wall of the heat exchange tube, which is constantly exposed to the waste gas, will accumulate a lot of impurities, affecting heat transfer efficiency. To improve the processing efficiency of high-efficiency heat exchange tubes, an inner wall cleaning device is needed. However, existing inner wall cleaning devices still have the following shortcomings:

[0003] When using existing internal wall cleaning equipment, most of the equipment lacks a corresponding limiting structure, which causes the cleaning components to easily shift position during the cleaning process of the heat exchange tube's inner wall. This can easily lead to damage to the inner wall of the heat exchange tube, affecting the subsequent use of the heat exchange tube and resulting in reduced practicality and efficiency of the internal wall cleaning equipment.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a high-efficiency heat exchange tube inner wall cleaning device. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency heat exchange tube inner wall cleaning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat exchange tube inner wall cleaning device, comprising a main housing, a movable receiving plate, and a cleaning movable rod. Limiting frames are installed on both sides of the main housing, and a servo motor is located at the center of the front end of each limiting frame. A lead screw is connected to the front end of the servo motor, and a movable slider is located outside the lead screw. A movable receiving plate is installed outside the movable slider, and limiting through holes are formed at the four corners inside the movable receiving plate. Limiting crossbars are connected inside the limiting through holes. A liquid inlet is located on the upper left side of the main housing, and a liquid outlet is located below the rear end of the main housing. A heat exchange tube body is connected inside the main housing, and an air inlet is located above the front end of the heat exchange tube body. A cleaning movable rod is connected inside the heat exchange tube body, and a scraper head is located at the front end of the cleaning movable rod.

[0007] Furthermore, there are two limiting frames, and the two limiting frames are symmetrically arranged on both sides of the outside of the main body with respect to the central axis of the front of the main body.

[0008] Furthermore, the external dimensions of the movable slider are adapted to the internal dimensions of the limiting frame, and the movable slider is slidably connected to the limiting frame via a lead screw.

[0009] Furthermore, the outer side of the movable receiving plate and the outer side of the movable slider are horizontally distributed, and the movable receiving plate is fixedly connected to the movable slider by bolts.

[0010] Furthermore, the internal dimensions of the limiting through hole are adapted to the external dimensions of the limiting crossbar, and the limiting crossbar is connected to the movable receiving plate through the limiting through hole.

[0011] Furthermore, the heat exchange tube body is embedded in the main housing, and the heat exchange tube body and the main housing are fixedly connected by bolts.

[0012] Furthermore, the cleaning rod is embedded in the heat exchange tube body and is slidably connected to the heat exchange tube body.

[0013] Furthermore, the external dimensions of the scraper head are adapted to the internal dimensions of the heat exchange tube body, and the outer side of the scraper head is in close contact with the inner wall of the heat exchange tube body.

[0014] This utility model provides a high-efficiency heat exchange tube inner wall cleaning device, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of a limiting crossbar, enables the servo motor to drive the lead screw to rotate during the use of the high-efficiency heat exchange tube inner wall cleaning equipment. This causes the movable slider connected to the outside of the lead screw to move accordingly, fixing the movable receiving plate on the outside of the movable slider. The movement of the movable slider drives the movable receiving plate to adjust its position. The limiting through hole, in conjunction with the limiting crossbar, increases the stability of the movable receiving plate during movement, thereby preventing the cleaning movable rod set on the inside of the movable receiving plate from shifting during use, and increasing the overall practicality and efficiency of the cleaning equipment.

[0016] 2. This utility model, through the setting of the cleaning movable rod, enables the liquid to be delivered into the main box through the liquid inlet set at the upper end of the main box during the use of the high-efficiency heat exchange tube inner wall cleaning equipment. The heated liquid is sent out in conjunction with the liquid outlet, and the heat exchange tube body is limited and installed inside the main box. Gas with a certain amount of heat is delivered into the heat exchange tube body through the air inlet. The movement of the movable receiving plate drives the cleaning movable rod to move in position, and the scraper head set at the front end of the cleaning movable rod scrapes the inner wall of the heat exchange tube body, further improving the overall practicality and efficiency of the cleaning equipment.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 3As shown, a high-efficiency heat exchanger tube inner wall cleaning device includes a main housing 1, a movable receiving plate 6, and a cleaning movable rod 13. Limiting frames 2 are installed on both sides of the main housing 1. A servo motor 3 is located at the center of the front end of each limiting frame 2, and a lead screw 4 is connected to the front end of the servo motor 3. A movable slider 5 is located outside the lead screw 4. The movable receiving plate 6 is installed outside the movable slider 5, and limiting through holes 7 are formed at the four corners inside the movable receiving plate 6. Limiting crossbars 8 are connected inside the limiting through holes 7. Two limiting frames 2 are provided, symmetrically arranged on both sides of the main housing 1 around the central axis of the front of the main housing 1. The external dimensions of the movable slider 5 are adapted to the internal dimensions of the limiting frames 2, and the movable slider 5 is slidably connected to the limiting frames 2 via the lead screw 4. The outer sides of the movable receiving plate 6 and the outer sides of the movable slider 5 are horizontally distributed, and the movable receiving plate 6 is fixedly connected to the movable slider 5 by bolts. The internal dimensions of the limiting through holes 7 and the external dimensions of the limiting crossbars 8 are... The dimensions of the parts are compatible, and the limiting crossbar 8 is connected to the movable receiving plate 6 through the limiting through hole 7. The limiting frame 2 is fixedly installed on both sides of the outside of the main box 1 by fastening bolts, and the servo motor 3 is fixedly installed on the front end of the outside of the limiting frame 2 with fastening bolts. The output shaft of the servo motor 3 is connected to the lead screw 4 through a coupling. The operation of the servo motor 3 drives the lead screw 4 to rotate, so that the movable slider 5 connected to the outside of the lead screw 4 moves accordingly, and the movable receiving plate 6 is fixedly installed on the outside of the movable slider 5. The movement of the movable slider 5 drives the movable receiving plate 6 to adjust its position. The internal dimensions of the limiting through holes 7 opened at the four corners of the movable receiving plate 6 are compatible with the external dimensions of the limiting crossbar 8. Thus, the limiting through holes 7 and the limiting crossbar 8 increase the stability of the movable receiving plate 6 during the movement process, thereby avoiding the positional deviation of the cleaning movable rod 13 set on the inside of the movable receiving plate 6 during use, and increasing the overall practicality and efficiency of the cleaning equipment.

[0023] like Figures 1 to 3As shown, a liquid inlet 9 is provided on the upper left side of the main housing 1, and a liquid outlet 10 is provided on the lower rear end of the main housing 1. A heat exchange tube body 11 is connected inside the main housing 1, and an air inlet 12 is provided on the upper front end of the heat exchange tube body 11. A cleaning rod 13 is connected inside the heat exchange tube body 11, and a scraper head 14 is provided on the front end of the cleaning rod 13. The heat exchange tube body 11 is embedded in the main housing 1 and is fixed to the main housing 1 by bolts. The cleaning rod 13 is embedded in the heat exchange tube body 11 and is slidably connected to the heat exchange tube body 11. The external dimensions of the scraper head 14 are consistent with the heat exchange tube body 11. The internal dimensions of the tube body 11 are adapted, and the outer side of the scraper head 14 is tightly fitted to the inner wall of the heat exchange tube body 11. Liquid is supplied to the inside of the main box 1 through the liquid inlet 9 set at the upper end of the main box 1, and the heated liquid is sent out in conjunction with the liquid outlet 10. The heat exchange tube body 11 is limited and installed inside the main box 1. Gas with a certain amount of heat is supplied to the inside of the heat exchange tube body 11 through the air inlet 12. The movement of the movable receiving plate 6 drives the cleaning movable rod 13 to move in position, and in conjunction with the scraper head 14 set at the front end of the cleaning movable rod 13, the inner wall of the heat exchange tube body 11 is scraped, further improving the overall practicality and efficiency of the cleaning equipment.

[0024] In summary, this high-efficiency heat exchange tube inner wall cleaning equipment operates by first rotating the lead screw 4 via the servo motor 3 at the front end of the limiting frame 2. This causes the movable slider 5 connected to the lead screw 4 to move accordingly. The movement of the movable slider 5 adjusts the position of the movable receiving plate 6. The limiting through hole 7, in conjunction with the limiting crossbar 8, increases the stability of the movable receiving plate 6 during movement, thus preventing the cleaning movable rod 13 on the inner side of the movable receiving plate 6 from shifting position during use. Next, liquid is supplied into the main housing 1 through the liquid inlet 9 at the upper end of the main housing 1, and the heated liquid is discharged through the liquid outlet 10. The heat exchange tube body 11 is then fixedly installed inside the main housing 1. Gas with a certain amount of heat is supplied into the heat exchange tube body 11 through the air inlet 12. The movement of the movable receiving plate 6 moves the cleaning movable rod 13, and the scraper head 14 at the front end of the cleaning movable rod 13 scrapes the inner wall of the heat exchange tube body 11, further improving the overall practicality and efficiency of the cleaning equipment.
