Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a liquid feed heat exchanger. Background Art

[0002] Heat exchangers are devices that transfer part of the heat of hot fluid to cold fluid, also known as heat exchangers. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used.

[0003] After searching, it is found that a liquid feed heat exchanger is disclosed in Chinese patent literature [Announcement No.: CN219390622U]. This liquid feed heat exchanger includes a box body, and the two opposite inner cavity side walls of the box body are provided with a plurality of evenly distributed T-shaped slots, and each T-shaped slot is plugged with a baffle plate for controlling the flow direction of the liquid, and all the baffle plates are staggered, and a plurality of groups of heat exchange serpentine tubes are placed between the baffle plates, and the heat exchange serpentine tubes are fixedly connected by a plurality of support columns, and the inner cavity bottom wall of the box body is fixedly welded with a limit column for limiting the installation position of the heat exchange serpentine tube, and the top of the box body is fixedly installed with a plurality of rotating seats, and each of the rotating seats is rotatably installed with a rotating bolt, and the top of each rotating bolt is threadedly connected with a limit block, and the top of the box body is covered with a box cover, and the box cover is fixedly installed with a plurality of limit seats, and the limit seat is provided with a groove for matching the limit block.

[0004] The heat exchanger disclosed in the patent is provided with a detachable structure, which is convenient for disassembly and cleaning. However, the disassembly method is to first rotate the turntable to cancel the limit between the limit block and the limit seat, and then rotate the rotating bolt to the bottom. Since there are four disassembly and assembly methods, the disassembly and assembly is more troublesome, and the two ends of the heat exchange serpentine tube are directly welded to the heat exchange main tube. If one of them has a crack, they need to be replaced as a whole, which increases the cost. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 As shown, a liquid feed heat exchanger comprises a box body 1, the left and right sides of the box body 1 are respectively connected with a first liquid inlet pipe 17 and a liquid discharge pipe 18, the front and rear sides of both sides of the box body 1 are provided with card slots 10, the inside of the box body 1 is provided with second liquid inlet pipes 2 on both sides, and a plurality of serpentine pipes 5 are respectively provided between the two second liquid inlet pipes 2, the outer surfaces of both ends of the serpentine pipes 5 are provided with external threads, the surface of one side of the second liquid inlet pipe 2 is respectively connected with a plurality of fixed pipes 3, the surface of the fixed pipe 3 is movably connected with a sealing sleeve 4, the inner side of the sealing sleeve 4 is threadedly connected with the surface of one end of the serpentine pipe 5, a box cover 6 is provided on the top of the box body 1, movable plates 7 are provided on both sides of the top of the inner cavity of the box cover 6, one end of the movable plate 7 is fixedly connected with a connecting plate 8, both sides of the bottom of the connecting plate 8 are fixedly connected with card plates 9 used in conjunction with the inside of the card slot 10, and the top of the box cover 6 is provided with a force structure 11 for driving the movable plate 7 to move.

[0024] The force-applying structure 11 includes a crank 111, a gear 112 and teeth 113. The crank 111 is arranged above the box cover 6. The bottom of the crank 111 is fixed to one side of the gear 112 through a rotating rod. There are several teeth 113, which are respectively fixed on the opposite sides of the left and right movable plates 7. The gear 112 is meshed with the movable plate 7 through the teeth 113. In this way, when the movable plate 7 is driven to move, the crank 111 can be rotated, and the gear 112 can be driven to rotate through the rotating rod. At the same time, the movable plate 7 is driven to move through the teeth 113, so as to facilitate the subsequent fixation between the box cover 6 and the box body 1.

[0025] Both sides of the top of the inner cavity of the box cover 6 are fixedly connected with movable rods 12, and the inside of the connecting plate 8 is movably connected to the surface of the movable rods 12, so that the connecting plate 8 can be auxiliary supported and its stability during movement can be maintained.

[0026] Limiting grooves 14 are provided on the front and rear sides of both sides of the top of the box body 1, and limiting rods 13 are fixedly connected to the front and rear sides of both sides of the bottom of the box cover 6 for use with the inside of the limiting grooves 14. This makes it easier for the box cover 6 to fit better with the top of the box body 1, thereby bringing convenience to the subsequent installation work.

[0027] Support plates 16 are fixedly connected to both sides of the inner cavity of the box body 1, and the inner side of the support plate 16 is clamped with the surface of the second liquid inlet pipe 2, so that the second liquid inlet pipe 2 can be auxiliary limited and its stability when placed can be maintained.

[0028] The inner wall of the card slot 10 is provided with a sealing gasket 15, which can not only increase the friction with the surface of the card plate 9, but also improve the sealing effect.

[0029] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and this technical solution will not be further elaborated.

[0030] Working principle: When in use, the first liquid with heat will enter the interior of the box body 1 through the first liquid inlet pipe 17, and then be discharged through the discharge pipe 18. Before entering, the second liquid enters through the second liquid inlet pipe 2, and then flows into the interior of the serpentine tube 5 through the fixed pipe 3, and is discharged through the second liquid inlet pipe 2 on the other side. During the circulation process, heat exchange treatment will be carried out. When one of the serpentine tubes 5 has a crack, the front and rear two movable plates 7 can be driven to move toward the opposite side through the force structure 11, and the connecting plate 8 and the card plate 9 can be driven to move together, so that the card plate 9 is separated from the inside of the card slot 10, and then the box cover 6 can be removed from the top of the box body 1, and then the second liquid inlet pipe 2 and the serpentine tube 5 can be taken out from the inside of the box body 1. Finally, according to the position of the cracked serpentine tube 5, the sealing sleeve 4 can be rotated accordingly, and the fixation of the serpentine tube 5 can be cancelled, so that it can be removed and replaced.
