Description

Technical Field

[0001] This utility model relates to the field of energy utilization, and in particular to a heat pipe heat exchanger with high heat absorption density. Background Technology

[0002] A heat pipe heat exchanger is a highly efficient heat exchange device that uses heat pipe technology to transfer heat between different media. In many industrial production processes such as steel, chemical, and cement, a large amount of high-temperature waste gas and waste liquid are generated as waste heat resources. Heat pipe heat exchangers can recover this waste heat, for example, by transferring the heat from the high-temperature waste gas to cold water to generate hot water or steam, which can be used for preheating and heating in the production process, or for heating in the factory area and supplying domestic hot water, effectively improving energy utilization and reducing energy consumption and production costs.

[0003] In the routine maintenance of heat pipe heat exchangers, when it is necessary to replace the heat exchange tubes, the staff will first remove the entire set of heat exchange tubes from the heat exchanger, then use tools to pull out the heat exchange tubes one by one, and then use tools to press the new heat exchange tubes into the original pipes.

[0004] The existing technology has the following drawbacks: In some existing equipment, when the heat exchange tubes are replaced, the staff needs to replace each heat exchange tube one by one. The operation is cumbersome, time-consuming and labor-intensive. Moreover, when the heat exchange tubes are used in the pipeline, dust and impurities will accumulate on the outer wall of the heat exchange tubes, affecting the heat exchange efficiency. Therefore, a heat pipe heat exchanger with high heat absorption density is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a heat pipe heat exchanger with high heat absorption density, aiming to improve the problem of cumbersome heat exchanger tube replacement steps in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heat pipe heat exchanger with high heat absorption density, comprising a base, a heat exchange tank fixedly connected to the top of the base, a sealing cover detachably installed on the inner wall of the heat exchange tank, a movable plate in contact with the inner wall of the heat exchange tank, a heat exchange tube inserted through and into the inner wall of the movable plate, a rectangular block inserted through and into the inner wall of the heat exchange tube, an elastic connection between the outer wall of the rectangular block and the movable plate via a movable spring, a movable column hinged to the right side wall of the rectangular block via a hinge rod, a fixed column slidably connected to the outer wall of the movable column, a limit mechanism provided at the right end of the fixed column, and a cleaning component provided on the inner wall of the top of the heat exchange tank;

[0007] The limiting mechanism includes a pull rod, with a plug inserted into the outer wall of the pull rod. The outer wall of the plug is elastically connected to the moving plate via a moving spring. The pull rod is fixedly connected to the right end of the fixed column.

[0008] As a further description of the above technical solution:

[0009] The cleaning assembly includes a gear, the outer wall of which meshes with a cleaning plate. An electric telescopic rod is fixedly connected to the left side wall of the cleaning plate, and the gear is rotatably connected to the inner top wall of the heat exchange tank.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the rectangular block is fixedly connected to one end of the movable spring, and the other end of the movable spring is fixedly connected to the inner wall of the rear end of the moving plate.

[0012] As a further description of the above technical solution:

[0013] The right sidewall of the rectangular block is hinged to one end of the hinge rod, and the other end of the hinge rod is hinged to the top of the movable column.

[0014] As a further description of the above technical solution:

[0015] The rectangular block is slidably connected to the right side wall of the moving plate, and the insert block is slidably connected to the right side wall of the moving plate.

[0016] As a further description of the above technical solution:

The cleaning plate is slidably connected to the inner wall of the top of the heat exchange tank. The movable end of the electric telescopic rod passes through and is slidably connected to the inner wall of the heat exchange tank.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by separating and overlapping the rectangular block with the heat exchange tube slot, a single heat exchange tube can be replaced. By separating and overlapping the insert block with the pull rod slot, the moving fixed column squeezes the movable column, releasing the positioning of all heat exchange tubes.

[0038] Reference Figure 4 - Figure 6 The outer wall of rectangular block 7 is fixedly connected to one end of movable spring 11, and the other end of movable spring 11 is fixedly connected to the inner wall of the rear end of movable plate 5. When rectangular block 7 moves backward, movable spring 11 is compressed. When resetting, the elastic force of movable spring 11 carries rectangular block 7 back to its original position. The right side wall of rectangular block 7 is hinged to one end of hinge rod 8, and the other end of hinge rod 8 is hinged to the top of movable column 9. Since the length of hinge rod 8 is constant, when movable column 9 moves to the left with one end of hinge rod 8, the hinge... The other end of the connecting rod 8 carries two sets of rectangular blocks 7 that are separated from each other. When the movable column 9 moves to the right with one end of the hinge rod 8, the other end of the hinge rod 8 carries two sets of rectangular blocks 7 that move closer together. The rectangular blocks 7 are slidably connected to the right side wall of the movable plate 5. The movable plate 5 has slots corresponding to the rectangular blocks 7, allowing the rectangular blocks 7 to move back and forth. The insert block 13 is slidably connected to the right side wall of the movable plate 5. The movable plate 5 has slots corresponding to the insert block 13, allowing the insert block 13 to move back and forth.

[0039] Reference Figure 5 - Figure 7 The outer wall of the insert 13 is fixedly connected to one end of the moving spring 14, and the other end of the moving spring 14 is fixedly connected to the inner wall of the rear end of the moving plate 5. When the insert 13 moves backward, the moving spring 14 is compressed. When resetting, the elastic force of the moving spring 14 is used to reset the insert 13. The heat exchange tube 6 passes through and is movably connected to the inner wall of the cleaning plate 15. The cleaning plate 15 has a slot corresponding to the heat exchange tube 6. The pull rod 12 passes through and is slidably connected to the inner wall of the moving plate 5. The moving plate 5 has a slot corresponding to the round rod, allowing the pull rod 12 to move left and right.

[0040] Working principle: When a single heat exchange tube 6 needs to be replaced, the operator can first remove the sealing cover 4, then remove the moving plate 5 along with the heat exchange tube 6 from the heat exchange tank 2. Next, the operator moves the movable column 9 to the left, which will move the hinge rod 8 to the left. The other end of the hinge rod 8 will cause the two sets of rectangular blocks 7 to separate from each other. The rectangular blocks 7 will compress the movable spring 11. When the rectangular blocks 7 separate from the groove of the heat exchange tube 6, the operator can remove the heat exchange tube 6 by hand. Then, the operator releases the movable column 9. Using the elastic force of the movable spring 11, the two sets of rectangular blocks 7 are brought closer together. When it is necessary to install the heat exchange tube 6, the hand moves the movable column 9 to the left. The movable column 9 will move the hinge rod 8 to the left, and the hinge rod 8 will separate the two sets of rectangular blocks 7. When the rectangular blocks 7 no longer block the heat exchange tube 6, the hand inserts the heat exchange tube 6 into the slot of the movable plate 5. At this time, the rectangular blocks 7 and the slot of the heat exchange tube 6 coincide. Release the movable column 9 to allow the rectangular blocks 7 to be inserted into the slot of the heat exchange tube 6, thus completing the positioning of the heat exchange tube 6.

[0041] When all heat exchange tubes 6 need to be replaced, move the insert block 13 backward. The insert block 13 will compress the moving spring 14. When the insert block 13 separates from the slot on the pull rod 12, move the pull rod 12 to the left. The pull rod 12 will move the fixed column 10 to the left. When the inner wall of the left end of the fixed column 10 contacts and compresses the movable column 9, move the movable column 9 to the left. The movable column 9 will move the hinge rod 8 along the same trajectory. When the rectangular block 7 separates from the slot on the heat exchange tube 6, the insert block 13 will coincide with the slot on the pull rod 12. Release the insert block 13 and use the elastic force of the moving spring 14 to insert the insert block 13 into the slot on the pull rod 12, thus limiting the pull rod 12. Then... The operator can remove all the heat exchange tubes 6. After the operator aligns the new heat exchange tube 6 and inserts it into the slot of the moving plate 5, the operator moves the insert block 13 backward and then moves the pull rod 12 to the right. The pull rod 12 will move the fixed column 10 to the right. When the inner wall of the left end of the fixed column 10 is no longer in contact with the movable column 9, the two sets of rectangular blocks 7 will be inserted into the slot of the heat exchange tube 6 under the elastic force of the movable spring 11, thus limiting the heat exchange tube 6. At the same time, the operator moves the pull rod 12 to the initial position and releases the insert block 13, allowing the insert block 13 to be inserted into the slot of the pull rod 12, thus limiting the pull rod 12. If the heat exchange tube 6 needs to be replaced again, the above operation steps can be repeated.

[0042] When the heat exchange tube 6 needs cleaning, the operator can use an externally controlled electric telescopic rod 3. The electric telescopic rod 3 will move the left cleaning plate 15 to the right. The left cleaning plate 15 will transmit power to the gear 16, which will move the right cleaning plate 15 to the left. The two sets of cleaning plates 15 will clean the outer wall of the heat exchange tube 6. When the two sets of cleaning plates 15 move to the middle of the heat exchange tube 6, the cleaning is complete. At this time, the electric telescopic rod 3 will move the left cleaning plate 15 to the left, and the gear 16 will move the right cleaning plate 15 to the right to the initial position. If the heat exchange tube 6 needs to be cleaned again, simply repeat the above operation steps.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
