Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, in particular to a heat exchange equipment. Background Art

[0002] The equipment that transfers heat from hot fluid to cold fluid is called heat exchange equipment. Heat exchange equipment is widely used in oil refining, chemical industry, light industry, pharmaceutical industry, machinery, food processing, power and atomic energy industry. Usually, in the equipment investment of some chemical plants, heat exchangers account for 30% of the total investment; in modern refineries, heat exchangers account for more than 40% of the total process equipment investment; in the desalination industry, almost all equipment is composed of heat exchangers. At present, most of the heat exchange equipment is directly installed by installing a protective shell on the outside and locking it with multiple locking screws. The installation is more troublesome and the space is limited. It is not convenient to flexibly replace the heat exchanger when there is a problem in use.

[0003] For example, a protective device for heat exchange equipment disclosed in a Chinese patent document (publication number: CN215984174U) works through two driving motors, indirectly driving two movable plates and the second shell and the third shell on the top to move and adjust, which is convenient for installing protection on both sides of the heat exchanger. During the installation process, the displacement length of the second shell and the third shell to the outside of the first shell can be adjusted according to the length of both sides of the heat exchanger, and heat exchangers of different lengths can be installed. The installation is flexible and convenient, and the heat exchanger structure can be flexibly replaced. However, when the heat exchanger is replaced and installed, the second shell and the third shell can only be moved to one end of the guide rod, which makes the heat exchanger body easily blocked by the second shell and the third shell during disassembly and replacement, increasing the difficulty of replacing the heat exchanger body, and the second shell and the third shell need to be started separately by motors when moving, which not only increases the equipment cost, but also easily leads to the problem of asynchronous movement of the second shell and the third shell at both ends.

[0024] The inner wall of the second protective shell 6 is provided with an elastic positioning device, and the elastic positioning device includes a movable rod 8 , and the outer surface of the movable rod 8 is movably sleeved with the inner wall of the second protective shell 6 .

[0025] One end of the movable rod 8 is fixedly connected to an arc-shaped positioning block 81, and the inner surfaces of the two arc-shaped positioning blocks 81 are respectively in contact with the two ends of the heat exchanger body 4. The outer surface of the movable rod 8 is movably sleeved with a support spring 82. The arc-shaped positioning block 81 plays a role in elastic positioning of the two ends of the heat exchanger body 4 through the cooperation of the movable rod 8 and the support spring 82. One end of the support spring 82 is fixedly connected to the outer surface of the arc-shaped positioning block 81, and the other end of the support spring 82 is fixedly connected to the inner wall of the second protective shell 6. The outer surface of the second protective shell 6 is provided with a movable slot 83. A servo motor 84 is fixedly installed on the upper surface of the support base 1. The output shaft of the servo motor 84 is fixedly installed with a worm 85 through a coupling. The inner walls of the two support blocks 2 are both installed with bidirectional screws 86 through bearings. The outer surface of the bidirectional screw 86 is fixedly sleeved with a worm wheel 87. The servo motor 84 drives the worm 85 to rotate clockwise and counterclockwise. The rotation of the worm 85 drives the bidirectional screw 86 to rotate through the meshing worm wheel 87.

[0026] The tooth surface of the worm wheel 87 meshes with the outer surface of the worm 85, and the outer surface of the bidirectional lead screw 86 is threadedly connected with a symmetrically distributed threaded block 88, and the lower surface of the threaded block 88 is fixedly connected with a guide block 89, and the inner wall of the guide block 89 is fixedly connected with a guide rod 810. The cooperation between the guide block 89 and the guide rod 810 can limit and guide the movement of the threaded block 88. One end of the guide rod 810 is fixedly connected to the side surface of the support block 2, and the upper surface of the threaded block 88 is fixedly connected with an arc-shaped support seat 811, and the inner surface of the arc-shaped support seat 811 is fixedly connected with a movable plug-in block 812. The outer surface of the movable plug-in block 812 is movably plugged into the inner wall of the movable slot 83, and the inner surface of the arc-shaped support seat 811 contacts the outer surface of the second protective shell 6. The arc-shaped support seat 811 cooperates with the movable slot 83 and the movable plug-in block 812 to position and support the second protective shell 6.

[0027] By setting up the elastic positioning device, elastic positioning protection is achieved for both ends of the heat exchanger body 4, and the second protective shells 6 at both ends are moved synchronously through a single driving source, thereby reducing equipment costs and facilitating the disassembly of the second protective shell 6, thereby facilitating the replacement of the heat exchanger body 4.

[0028] Working principle: Step 1, when replacing the heat exchanger body 4, start the servo motor 84 to drive the worm 85 to rotate counterclockwise, the rotation of the worm 85 drives the bidirectional screw 86 to rotate through the meshing worm wheel 87, the rotation of the bidirectional screw 86 drives the threaded block 88 to move through the limiting cooperation of the guide block 89 and the guide rod 810, the movement of the threaded block 88 drives the second protective shell 6 to move through the cooperation of the arc support seat 811 and the movable plug block 812, so that the limiting plug strip 7 moves out of the limiting slot 5, and then the second protective shell 6 is lifted up, so that the movable slot 83 is separated from the movable plug block 812, and the second protective shell 6 is disassembled, so as to facilitate the replacement of the heat exchanger body 4;

[0029] Step 2. After the replacement is completed, align the second protective shell 6 with the movable plug block 812 through the movable slot 83 for insertion and limiting, and support the second protective shell 6 through the arc support seat 811, and then start the servo motor 84 to drive the worm 85 to rotate clockwise. The rotation of the worm 85 drives the bidirectional screw 86 to rotate through the meshing worm gear 87, thereby driving the two second protective shells 6 to move relative to each other, and making the limiting plug strip 7 move and insert into the limiting slot 5. At the same time, the arc positioning block 81 contacts the two ends of the heat exchanger body 4, and through continuous movement, the support spring 82 is squeezed and contracted, and then the servo motor 84 is stopped. At this time, the arc positioning block 81 elastically squeezes and positions the two ends of the heat exchanger body 4 through the elastic force of the support spring 82.
