Description

Technical Field

[0001] The present application relates to the technical field of heat exchangers, and in particular to a heat exchanger tube bundle disassembly and assembly device. Background Art

[0002] Heat exchanger tube bundle disassembly and assembly equipment is mainly used to maintain and repair heat exchangers in the chemical, petroleum, power, food and other industries. Heat exchangers are key equipment for transferring heat in these industries. During the production process, they may need to replace or repair the tube bundle due to long-term use, corrosion, blockage and other reasons. Heat exchanger tube bundle disassembly and assembly equipment can improve the efficiency of disassembly and assembly and maintenance.

[0003] After searching, the Chinese patent publication number CN201721223530.8 discloses a heat exchanger tube bundle disassembly and assembly device, which relates to the field of disassembly and assembly technology. Although the device enters the heat exchanger through an electric telescopic rod to clean the parts, the pulley will first contact the surface of the heat exchanger while entering to prevent the brushes from entering and hitting the heat exchanger shell, causing damage to the equipment. At the same time, when the pulley enters the heat exchanger, it will push the sealing block to rotate downward, open the water outlet to spray cleaning liquid, and start the motor to rotate. During the rotation, the brush will clean the inner wall of the heat exchanger, and no manual cleaning is required, thereby improving the overall work efficiency. However, when the device disassembles the tube bundle inside the heat exchanger, the tube bundle is subjected to the action of corrosive media for a long time, and the connection part between the tube bundle and the tube sheet may adhere due to rust, making disassembly difficult. At the same time, the device has limitations on the length of the heat exchanger and cannot support heat exchangers of various lengths and sizes, thereby reducing the applicability of the device. Summary of the invention

By rotating the second threaded rod, the second threaded rod can drive the two sliders to move relative to each other, thereby controlling the contact and separation of the support wheel and the heat exchanger body.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] (1) A heat exchanger tube bundle disassembly and assembly device. During the maintenance and operation of the heat exchanger, the heat exchanger is hoisted to the top of the support mechanism by a hydraulic lifting column, and the clamping seat is pushed to move by a hydraulic cylinder to clamp the heat exchanger body. At the same time, the first transmission gear and the first driven gear rotate synchronously to drive the drive shaft to move the heat exchanger body in the horizontal direction so that the ejector block can eject and loosen the rusty tube bundle inside to facilitate extraction.

[0017] (2) A heat exchanger tube bundle disassembly and assembly device, which is driven by a first motor of a spacing adaptation mechanism to drive a first threaded rod to rotate. The first threaded rod can drive two sliding seats to move while rotating. Since the threads at both ends of the first threaded rod are opposite, the sliding seats at both ends of the first threaded rod can move in opposite directions synchronously, thereby adjusting the spacing between the two supporting mechanisms, which is beneficial for the two supporting mechanisms to adjust the appropriate spacing according to the length of the heat exchanger body, thereby helping to reduce the limitation on the length of the heat exchanger body.

[0018] (3) A heat exchanger tube bundle disassembly and assembly equipment. When disassembling and maintaining the heat exchanger, the hydraulic lifting column is responsible for pushing it upward. Driven by the third motor of the driving mechanism, the second transmission gear will drive the second driven gear to rotate, thereby driving the rotating shaft to rotate. The rotation of the rotating shaft causes the heat exchanger body to rotate accordingly. Such a design helps to properly handle the weight of the heat exchanger and maintain structural stability during the disassembly process, avoiding equipment damage or personal injury caused by uneven weight distribution or unstable structure. In addition, this rotation mechanism makes disassembly more convenient, especially when it is necessary to operate from different angles or positions, which can reduce the movement of staff and additional lifting operations, improve work efficiency and reduce operational risks. In this way, it can ensure that the maintenance and disassembly of the heat exchanger are carried out safely and efficiently. BRIEF DESCRIPTION OF THE DRAWINGS
