Description
Technical Field
[0001] This utility model relates to the technical field, specifically to a high-efficiency detachable plate heat exchanger. Background Technology
[0002] A plate heat exchanger is a heat exchange device consisting of a series of parallel, thin metal plates that transfer heat between two fluids (hot and cold) through narrow channels between the plates. It utilizes the high thermal conductivity and large surface area of the metal plates to efficiently transfer heat from the hot fluid to the cold fluid, thereby achieving heating or cooling.
[0003] Traditional plate heat exchangers are connected by numerous clamping bolts between fixed and movable clamping plates. When assembling or disassembling a plate heat exchanger, the nuts on these clamping bolts must be removed. Because the clamping bolts are very long, this process is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0024] like Figures 1-3 As shown, this utility model discloses a high-efficiency detachable plate heat exchanger, including an upper guide rod 1 and a lower guide rod 2 arranged in parallel. A fixed clamping plate 3 is fixedly connected between one end of the upper guide rod 1 and the lower guide rod 2, and a column 4 is fixedly connected between the other end of the upper guide rod 1 and the lower guide rod 2. A movable clamping plate 5 is provided between the column 4 and the fixed clamping plate 3. The top and bottom ends of the movable clamping plate 5 are slidably connected to the upper guide rod 1 and the lower guide rod 2, respectively. A heat transfer plate assembly 6 is provided between the fixed clamping plate 3 and the movable clamping plate 5, and the upper and lower ends of the heat transfer plate assembly 6 are slidably connected to the upper guide rod 1 and the lower guide rod 2.
[0025] The fixed clamping plate 3 is provided with a first fixed pulley 7 and a sixth fixed pulley 12 on its upper and lower sides, respectively. The upper side of the column 4 is provided with a second fixed pulley 8 and a third fixed pulley 9, and the lower side of the column 4 is provided with a fourth fixed pulley 10 and a fifth fixed pulley 11. The third fixed pulley 9 is set higher than the second fixed pulley 8 in the vertical direction and is staggered with the second fixed pulley 8 in the horizontal direction. The fifth fixed pulley 11 is set lower than the fourth fixed pulley 10 in the vertical direction. The fifth fixed pulley 11 is staggered with the fourth fixed pulley 10 in the horizontal direction. A drive motor 13 is provided in the middle of the column 4. The output end of the drive motor 13 is coaxially fixedly connected to a rotating shaft 14. A traction rope 15 is wound between the first fixed pulley 7, the second fixed pulley 8, the third fixed pulley 9, the fourth fixed pulley 10, the fifth fixed pulley 11, and the sixth fixed pulley 12. The traction rope 15 is wound on the rotating shaft 14 and is fixedly connected to the movable pressure plate 5.
[0026] The aforementioned upper guide rod 1 and lower guide rod 2 are straight rod structures, arranged parallel to each other with their ends aligned. A fixing plate 3 is positioned at the lower ends of the upper guide rod 1 and lower guide rod 2. The upper guide rod 1 is fixed to the inner side of the upper edge of one side (the wider side) of the fixing plate 3, and the lower guide rod 2 is fixed to the inner side of the lower edge of the fixing plate 3, preferably on the same horizontal plane. A column 4 is provided at the other end of the upper guide rod 1 and lower guide rod 2, with its upper and lower ends fixedly connected to the upper guide rod 1 and lower guide rod 2 respectively. In this embodiment, the column 4 is constructed using a die-casting process. The steel structure has an upper guide rod 1 and a lower guide rod 2 fixedly connected to the upper and lower sides of one of the grooves in the column 4. The groove on the other side of the column 4 serves as the mounting groove for the drive structure. A movable clamping plate 5 is set between the column 4 and the fixed clamping plate 3. Specifically, the top of the movable clamping plate 5 has a groove that matches the shape of the upper guide rod 1. The upper guide rod 1 is placed in the groove and serves as the guide groove structure for the movable clamping plate 5. The lower guide rod 2 is set through the movable clamping plate 5 on the inner side of the lower edge, so that the movable clamping plate 5 can slide left and right along the upper guide rod 1 and the lower guide rod 2.
[0027] The heat transfer plate assembly 6 mentioned above is composed of multiple heat transfer plate assemblies 6. Grooves are provided on both the upper and lower sides to match the shapes of the upper guide rod 1 and the lower guide rod 2, respectively, so that the heat transfer plate can be locked between the upper guide rod 1 and the lower guide rod 2 through the grooves on the upper and lower sides, and can slide along the upper guide rod 1 and the lower guide rod 2.
[0028] The specific configuration of the pulley system described above is as follows: One fixed pulley (7) is installed at the top and one at the bottom of the fixed pressure plate 3, namely a first fixed pulley 7 and a sixth fixed pulley 12. The first fixed pulley 7 is mounted via a pulley seat, and its bottom is a certain distance from the top surface of the fixed pressure plate 3, specifically high enough not to affect the movement of the traction rope 15. The sixth fixed pulley 12 is similarly configured and will not be elaborated further. Two fixed pulleys are installed at the top and two at the bottom of the column 4. The two upper fixed pulleys are the second fixed pulley 8 and the third fixed pulley 9, and the two lower fixed pulleys are the fourth fixed pulley 10 and the fifth fixed pulley 11. The second fixed pulley 8 is installed in a groove on the outside of the column 4, and is positioned between two fixed plates installed in the groove. Meanwhile, the pulley groove of the second fixed pulley 8 is slightly higher than the top surface of the column 4, which facilitates the connection of the traction rope 15. The third fixed pulley 9 is installed between two fixed plates installed on the outer side of the top surface of the column 4, so that the pulley groove at the top of the third fixed pulley 9 is higher than that of the second fixed pulley 8, and the pulley groove on the right side is placed outside the pulley groove of the second fixed pulley 8 to avoid interference with the traction rope 15. The fourth fixed pulley 10 and the fifth fixed pulley 11 are installed in the outer groove at the bottom of the column 4. The specific installation method is the same as that of the second fixed pulley 8 and the third fixed pulley 9. The fourth fixed pulley 10 corresponds to the second fixed pulley 8, and the fifth fixed pulley 11 corresponds to the third fixed pulley 9. This will not be described in detail here.
[0029] The traction rope 15 is configured such that it starts from the top pulley groove of the first fixed pulley 7, connects to the third fixed pulley 9, passes over the top of the third fixed pulley 9 and connects to the fifth fixed pulley 11, passes over the bottom of the fifth fixed pulley 11 and connects to the sixth fixed pulley 12, then passes around the bottom of the sixth fixed pulley 12 and connects to the fourth fixed pulley 10, passes over the outside of the fourth fixed pulley 10 and connects to the second fixed pulley 8, passes over the top of the second fixed pulley 8 and connects to the bottom of the first fixed pulley 7, then passes back to the top of the first fixed pulley 7 to form a closed loop. The traction rope 15 is connected from the top of the third fixed pulley 9 to the third fixed pulley 9. When the second fixed pulley 8 is connected to the bottom of the first fixed pulley 7, the traction rope 15 passes through the top of the movable pressure plate 5 and is fixed together with the movable pressure plate 5, so that the movable pressure plate 5 can slide left and right as the traction rope 15 moves. Similarly, when the traction rope 15 is connected to the sixth fixed pulley 12 at the bottom of the fifth fixed pulley 11, it passes through the bottom of the movable pressure plate 5 (that is, the traction rope 15 on the lower side of the bottom, the traction rope 15 on the upper side of the bottom and the lower guide rod 2 can pass through the slot on the movable pressure plate 5) and is fixed together, so that the movable pressure plate 5 can move left and right with the traction rope 15.
[0030] The driving mechanism for the traction rope 15 is specifically configured such that a drive motor 13 is horizontally installed in the middle of the column 4, and the drive motor 13 is fixedly connected to the column 4. A rotating shaft 14 is coaxially fixedly connected to the output shaft of the drive motor 13. The rotating shaft 14 is configured such that the radius gradually decreases from both ends to the middle. The traction ropes 15 in both directions are wound around the rotating shaft 14 at least once to ensure the friction between the traction ropes 15 and the rotating shaft 14, so that when the drive motor 13 rotates and drives the rotating shaft 14 to rotate, it can drive the traction ropes 15 to move accordingly.
[0031] In a further embodiment, the top end of the second fixed pulley 8 is set at the same horizontal level as the bottom end of the first fixed pulley 7, the top end of the third fixed pulley 9 is set at the same horizontal level as the top end of the first fixed pulley 7, the bottom end of the fourth fixed pulley 10 is set at the same horizontal level as the top end of the sixth fixed pulley 12, and the top end of the fifth fixed pulley 11 is set at the same horizontal level as the bottom end of the sixth fixed pulley 12. The second fixed pulley 8 and the fourth fixed pulley 10 are vertically aligned, and the third fixed pulley 9 and the fifth fixed pulley 11 are vertically aligned.
[0032] By setting the pulley groove height of multiple fixed pulleys to be consistent, the wrap angle between the traction rope 15 and the fixed pulley can be large enough to avoid slippage and thus reduce transmission efficiency.
[0033] In a further embodiment, a control cabinet is provided on the column 4, and a laser rangefinder 16 is provided on the movable clamping plate 5 and the fixed clamping plate 3 to detect the distance between the movable clamping plate 5 and the fixed clamping plate 3. The laser rangefinder 16 is electrically connected to the control cabinet, and the drive motor 13 is electrically connected to the control cabinet.
[0034] The aforementioned control cabinet allows for input of the required plate bundle dimensions. The drive motor 13 then moves the movable clamping plate 5 via the traction rope 15, enabling its forward and backward movement. When assembling the plate heat exchanger, the movable clamping plate 5 moves forward; when disassembling the plate heat exchanger, it moves backward. As the movable clamping plate 5 moves, the laser distance sensor 16 located on it also moves. The laser distance sensor 16 measures the distance between the fixed clamping plate 3 and the movable clamping plate 5, which is the plate bundle dimension input on the control cabinet. This data is transmitted to the control cabinet in real time. When the preset distance is reached, the control cabinet stops the drive motor 13. This allows for quick assembly and disassembly of the plate heat exchanger without requiring manual removal and tightening of the clamping bolts or movement of the movable clamping plate 5, significantly saving manpower and resources.
[0035] In some other embodiments, a seventh fixed pulley 17 is provided on the top of the movable clamping plate 5, and the traction rope 15 passes through the upper and lower sides of the seventh fixed pulley 17 respectively.
[0036] By setting a seventh fixed pulley 17 on the top of the movable pressure plate 5, the friction during the movement can be reduced, making it easier to move the movable pressure plate 5 when the movable pressure plate 5 is heavy and the traction rope 15 itself is difficult to pull.
[0037] The above specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0038] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
[0039] The present invention has been described in a relatively specific and detailed manner above through general description and specific embodiments. It should be noted that, without departing from the concept of the present invention, various modifications and improvements can be made to these specific embodiments, all of which fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
