Description
Technical Field
[0001] This utility model relates to the technical field of internal ribbed evaporators, and in particular to an easy-to-clean internal ribbed evaporator. Background Technology
[0002] A plate evaporator is an evaporation device that uses metal plates as heat transfer elements. It achieves thin-film evaporation by transferring heat through fins. The solution to be evaporated is heated and boils rapidly in the evaporator, causing it to vaporize quickly. During the evaporation process, the liquid rises and forms a liquid film along the heat exchange wall, allowing the liquid to flow over the heated surface in a liquid film form, thus achieving rapid evaporation and vaporization.
[0003] Plate evaporators have advantages such as high heat transfer efficiency, low heat loss, fast evaporation speed, compact structure, small equipment footprint, and convenient adjustment of processing capacity. However, after a period of use, some dirt often accumulates on the fins of the plate evaporator. Therefore, the fins need to be cleaned after a period of use to avoid affecting its evaporation efficiency.
[0004] The existing Chinese utility model patent with authorization announcement number CN219560625U discloses a plate evaporator. This patent solves to some extent the problem that users need to manually operate the device to remove the bolts to achieve disassembly, which is complicated, lacks a suitable fixing and limiting mechanism, and has low disassembly and assembly efficiency.
[0005] The patent document uses a structure including a U-shaped frame, locking rod, threaded hole, locking seat, locking hole, and rotating ring. The locking rod is inserted into the locking seat in the evaporator plate to fix it. The evaporator plate needs to be moved to the appropriate position first, and then the locking rod is rotated to insert it into the locking seat. Since there are often many evaporator plates in the evaporator, it takes a long time to separate and fix the evaporator plates, which affects the cleaning efficiency.
[0006] Therefore, this application provides an easy-to-clean internal ribbed evaporator to overcome the shortcomings of the prior art. Utility Model Content

[0029] To make the technical means, technical features, utility model purpose and technical effects of this utility model easy to understand, the present utility model will be further described below with reference to specific illustrations. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0030] Example 1
[0031] like Figures 1 to 8 As shown: An easy-to-clean internal ribbed evaporator includes a fixed plate 1, a plurality of ribs on the right side of the fixed plate 1, and a movable plate 3 on the right side of the ribs 2. Three screws 4 are installed through the fixed plate 1, ribs 2, and movable plate 3. A nut 41 is threadedly connected to the end of each screw 4, i.e., the right side of the movable plate 3. One screw 4 is located above the other two screws 4. The upper screw 4 passes through the top of the fixed plate 1, ribs 2, and movable plate 3, while the two lower screws 4 are arranged opposite each other and pass through the lower sides of the fixed plate 1, ribs 2, and movable plate 3. The three screws 4 are used to tightly connect the fixed plate 1, ribs 2, and movable plate 3 into a whole during evaporation, ensuring that the evaporator can operate stably.
[0032] like Figure 3As shown: Both the fixed plate 1 and the movable plate 3 have one connecting hole 11, two opposite connecting holes 12, and two opposite connecting holes 13. The rib plate 2 also has five corresponding connecting holes. The two connecting holes 12 in the fixed plate 1 have internal threads. The side of the fixed plate 1 near the rib plate 2 and the side of the movable plate 3 near the rib plate 2 each have two opposite connecting grooves 14. The connecting grooves 14 engage with the lower connecting plate 5 and the upper connecting plate 6. The connecting grooves 14 include a vertically arranged slot 15, the bottom of which is connected to a slot 2 16. The side of the slot 15 near the rib plate 2 is connected to... The first slot 15 has a horizontally arranged slot 17. The side of the first slot 15 near the rib plate 2 is also connected to a slot 4 18, which is located above the third slot 17. The fourth slot 4 18 is inclined and its height near the first slot 15 is higher than its height away from the first slot 15. The cross-sections of the first slot 15, the second slot 16, and the third slot 17 are convex, with the smaller end set on the surface of the fixed plate 1 (movable plate 3). The groove depth of the second slot 16 is the same as the groove depths of the first slot 15, the second slot 16, and the third slot 17. The second slot 16 is a rectangular groove, and its cross-section is also rectangular.
[0033] like Figure 1 , Figure 2 , Figure 7 As shown: On the side of the movable plate 3 away from the fixed plate 1, there are two threaded posts 31 opposite each other. The two threaded posts 31 are respectively connected to the two connecting holes 12 on the movable plate 3. The outer wall of the threaded post 31 is provided with threads. The threaded post 31 is connected to a nut 32 by the external thread. The nut 32 is mainly used to prevent the inner connecting rod 72 from protruding from the outer sleeve 71 when the evaporator is in normal use.
[0034] like Figures 1 to 6As shown: Two opposing lower connecting plates 5 are snapped between the fixed plate 1 and the movable plate 3. The two lower connecting plates 5 are located on the front and rear sides of the bottom of the rib plate 2. Each of the two lower connecting plates 5 has an upper connecting plate 6 above it, for a total of two upper connecting plates 6. The lower connecting plate 5 can be movably connected to the upper connecting plate 6 directly above it. The lower connecting plate 5 is L-shaped, and a plurality of partition plates 51 are fixed on its inner side (the side closer to the rib plate 2). The number of partition plates 51 is greater than the number of rib plates 2. Two columns 52 are fixed on the top of each lower connecting plate 5. A snap-fit mechanism is fixed on each side of the top of the lower connecting plate 5. The snap-fit mechanism includes a column 53 fixedly connected to the side wall of the lower connecting plate 5. A column 54 is fixed at the end of the column 53 away from the lower connecting plate 5. The radial cross-sectional diameter of the column 54 is greater than the radial cross-sectional diameter of the column 53. The lower connecting plate 5 is movably connected to the slot 17 through the snap-fit mechanisms at both ends.
[0035] like Figures 1 to 6 As shown: Each of the upper connecting plates 6 has two connecting grooves at its bottom. The upper connecting plate 6 is movably connected to the lower connecting plate 5 through the connecting grooves and the first column 52. A snap-fit mechanism is fixed on each of the two sides of the top of the upper connecting plate 6. The snap-fit mechanisms at both ends of the upper connecting plate 6 are exactly the same as those at both ends of the lower connecting plate 5. The connection method between the upper connecting plate 6 and its two end snap-fit mechanisms is the same as that between the lower connecting plate 5 and its two end snap-fit mechanisms. Each snap-fit mechanism includes a second column 53 and a third column 54. In the upper connecting plate 6, the second column 53 is fixedly connected to one end of the upper connecting plate 6, and the third column 54 is fixed to the end of the second column 53 away from the upper connecting plate 6. The upper connecting plate 6 is movably connected to the slot 18 through the snap-fit mechanisms at both ends.
[0036] like Figures 1 to 7 As shown: A telescopic rod 7 is also installed through the fixed plate 1, the rib plate 2, and the movable plate 3. The telescopic rod 7 includes an outer sleeve 71, which is hollow inside and has an inner connecting rod 72 slidably connected inside. The cross-sectional diameter of the outer sleeve 71 is larger than that of the inner connecting rod 72. One end of the inner connecting rod 72 is located inside the outer sleeve 71 and cannot be detached from it. A spring is provided inside the outer sleeve 71. One end of the spring is fixedly connected to the inner left side wall of the outer sleeve 71, and the other end is fixedly connected to the left side wall of the inner connecting rod 72. An external thread 73 is provided on the outer side wall of the outer sleeve 71. The outer sleeve 71 is threadedly connected to the connecting hole 12 in the fixed plate 1 through the external thread 73.
[0037] Working method: First, remove the nut 32 from the threaded post 31, allowing the inner connecting rod 72 to extend from the outer sleeve 71. Remove the nut 41 from the screw 4. Then, remove the screw 4 from the connecting hole 11 and the connecting hole 33. Move the movable plate 3 a certain distance away from the fixed plate 1, dispersing the ribs 2. Insert the upper connecting plate 6 into the lower connecting plate 5. Place the snap-fit mechanism at both ends of the lower connecting plate 5 and the upper connecting plate 6 into the slot 2 16. Move the lower connecting plate 5 and the upper connecting plate 6 upward along the slot 1 15, placing a rib 2 between every two partitions 51 and two partitions 61 (of course, there can also be two or more ribs 2). When the 5-section moves to the same height as slot 3 17, separate the lower connecting plate 5 from the upper connecting plate 6. The lower connecting plate 5 moves into slot 3 17, and the upper connecting plate 6 continues to move upward along slot 1 15 until its top height is the same as slot 4 18. Move the upper connecting plate 6 into slot 4 18, and then clean the rib plate 2. After cleaning, gather the rib plate 2 towards the side of the fixed plate 1, and move the movable plate 3 towards the side of the fixed plate 1 to retract the inner connecting rod 72 into the outer sleeve 71. Thread the nut 32 to the threaded post 31, pass the screw 4 through the connecting hole 1 11 and the connecting hole 3 13, and then thread the nut 1 41 to the screw 4 to reassemble the evaporator.
[0038] Example 2
[0039] During the implementation of Example 1, we found that Example 1 was able to meet our needs. However, when cleaning the rib plate 2, we found that the telescopic rod 7, which needs to bear a certain load, is prone to deformation after repeated cleaning, and the spring is prone to fatigue.
[0040] like Figure 8 As shown: A connecting rod 8 is threadedly connected to the connecting hole 12 of the fixing plate 1. The connecting rod 8 includes a connecting rod 81. The outer side wall of the connecting rod 81 is provided with a connecting thread 82. The connecting rod 81 is threadedly connected to the connecting hole 12 of the fixing plate 1 through the connecting thread 82. The connecting rod 81 has an internal threaded hole 83. A connecting rod 84 is screwed into the connecting rod 81. A connecting post 85 is fixed to one end of the connecting rod 84 near the connecting rod 81. The outer side wall of the connecting post 85 is provided with a thread. The connecting post 85 is screwed into the internal threaded hole 83 of the connecting rod 81 through the thread on its outer side wall.
[0041] Replace the telescopic rod 7 with the connecting rod 8. When cleaning is required, simply rotate the connecting rod 84. Compared to the telescopic rod 7, the connecting rod 8 is more stable and has a longer service life.
