Description

Technical Field

[0001] The utility model belongs to the technical field of plate heat exchangers, and more specifically, it relates to a high-efficiency plate heat exchanger for a ship ballast water system. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, enabling the fluid temperature to reach the specified index of the technological process. Heat exchangers have become one of the indispensable important devices on ships. For example, heat exchangers are used in equipment such as main and auxiliary engine lubricating oil coolers, cylinder jacket fresh water coolers, fuel heaters, steam condensers, and feed water heaters. However, the special working environment of ships places very strict requirements on heat exchangers. The special environment includes factors such as instability on the sea surface, and may encounter working conditions such as vibration, shock, large-angle inclination, and noise.

[0003] In a Chinese patent for a plate heat exchanger (application publication number: CN118310339A), the device includes a heat exchanger body, and a plate assembly is detachably arranged on the heat exchanger body. The plate assembly includes a plurality of first plates and a plurality of second plates. The first plates and the second plates are arranged alternately in sequence, and a plurality of first heat exchange channels and second heat exchange channels are formed at intervals. A sealing strip is connected between adjacent first plates and second plates, and the sealing strip is formed by an elastic material. The adjusting assembly includes a movable clamping plate, a first adjusting rod, and a second adjusting rod. When cleaning the plate heat exchanger, this patent can increase the distance between adjacent first plates and second plates, and make the first heat exchange channels and the second heat exchange channels communicate with each other, so that the plate assembly can be cleaned without disassembly, improving the cleaning efficiency. At the same time, through the continuous change of the positions of the first plates and the second plates, the cleaning effect can be enhanced, and slag and scale blockage of the heat exchanger body can be avoided. However, this device uses a plurality of cylinders to achieve the displacement adjustment of the movable clamping plate, resulting in a high equipment investment cost, difficult later maintenance, and in case of special situations such as power failure, it cannot work normally, thus affecting the operation of cleaning the plate assembly.

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer and more understandable, the following further details this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0025] Please refer to Figures 1-5 , in this practical embodiment, a high-efficiency plate heat exchanger for a ship ballast water system is provided, including a fixed pressing plate 1, a movable clamping plate 2, a plate assembly 3 installed between the fixed pressing plate 1 and the movable clamping plate 2, and a concave-shaped vertical frame 4. Positioning and guiding mechanisms arranged at equal intervals are successively provided between the side walls on both sides of the fixed pressing plate 1 and the movable clamping plate 2 from top to bottom. A fluid port 5 communicated with the plate assembly 3 is provided on the side wall of the fixed pressing plate 1. The upper side wall of the horizontal and straight end of the concave-shaped vertical frame 4 is a hollow structure, and a translation adjustment mechanism is provided in the upper side wall of the horizontal and straight end of the concave-shaped vertical frame 4. Both ends of the translation adjustment mechanism are fixedly connected to the movable clamping plate 2. The plate assembly 3 includes a first plate and a second plate. Both the first plate and the second plate are provided in multiple numbers. The multiple first plates and the multiple second plates are arranged alternately in sequence, and a plurality of first heat exchange channels and second heat exchange channels arranged at intervals are formed. The two fluid ports 5 located above are communicated with the first heat exchange channel, and the two fluid ports 5 located below are communicated with the second heat exchange channel.

[0026] In this embodiment, a sealing strip is connected between adjacent first plates and second plates. The sealing strip is formed by an elastic material. Here is the prior art mentioned in the background technology, so no more explanations are made here.

[0027] Specifically, the translation adjustment mechanism includes a lead screw 6 rotatably arranged on the upper side wall of the horizontal and straight end of the concave vertical frame 4. One end of the lead screw 6 penetrates to the outside of the concave vertical frame 4 and is fixedly connected with a rotary block 7. A nut block 8 is threadedly connected to the lead screw 6 in the concave vertical frame 4. Two symmetrically arranged connecting frames 9 are fixedly connected to both sides of the nut block 8. Slide openings 10 are formed on both sides of the horizontal and straight end of the concave vertical frame 4. The two connecting frames 9 respectively pass through the two slide openings 10 and are fixedly connected to the movable clamping plate 2. A limiting mechanism for limiting the rotation of the rotary block 7 is fixedly connected to the upper side wall of the concave vertical frame 4.

[0028] When it is necessary to adjust the displacement of the movable clamping plate 2, only need to rotate the rotary block 7 to drive the lead screw 6 to rotate. Since the lead screw 6 is threadedly connected to the nut block 8, at this time, the nut block 8 is forced to displace, and then drive the two connecting frames 9 to displace simultaneously, so as to realize the displacement adjustment of the movable clamping plate 2. The operation is simple and convenient. Compared with driving and adjusting by a cylinder, the manufacturing cost is lower and the subsequent maintenance is more convenient. At this time, the plate assembly 3 can be stretched and unfolded for cleaning. This is the prior art mentioned in the background technology, so no more explanations will be made here.

[0029] In this embodiment, as Figure 3 and Figure 5 shown, the limiting mechanism includes a fixed strip shell 11 fixed on the upper side wall of the concave vertical frame 4. A slider 12 is slidably connected in the fixed strip shell 11. A compression spring 13 is fixedly connected between the inner wall of the fixed strip shell 11 and the slider 12. A push block 14 is fixedly connected to the upper end of the slider 12. An opening 15 is formed on the upper side wall of the fixed strip shell 11. The push block 14 passes through the opening 15. One end of the slider 12 away from the compression spring 13 is fixedly connected with a limiting rod 16. Equally spaced and circumferentially arranged limiting grooves 17 are formed on the side wall of the rotary block 7. One end of the limiting rod 16 is inserted into one of the limiting grooves 17. When it is necessary to rotate the rotary block 7, first push the push block 14 to displace, driving the limiting rod 16 fixed to the slider 12 to displace. At this time, the compression spring 13 is compressed and contracts to generate an elastic force until the limiting rod 16 is separated from the limiting groove 17. At this time, the rotation of the rotary block 7 is no longer restricted, and the rotary block 7 can be rotated to adjust the displacement of the movable clamping plate 2. After adjustment, release the push block 14. At this time, using the elastic force of the compression spring 13, the limiting rod 16 can be automatically inserted into the limiting groove 17 to limit and lock the rotation of the rotary block 7, making the positioning of the movable clamping plate 2 more stable and preventing the displacement of the movable clamping plate 2 due to vibration and other reasons during the navigation of the ship.

[0030] Furthermore, as Figure 5 shown, a slide hole is formed at one end of the fixed strip shell 11. The limiting rod 16 passes through the slide hole, which is convenient for the displacement of the limiting rod 16.

[0031] As Figure 1As shown in the figure, the positioning and guiding mechanism includes a guiding threaded column 18. The guiding threaded column 18 is inserted through and arranged on the fixed pressing plate 1 and the movable clamping plate 2. The guiding threaded column 18 is fixedly connected to the fixed pressing plate 1 through a fastening bolt 19, which is detachable. The movable clamping plate 2 is slidably connected to the guiding threaded column 18 through a guiding sliding sleeve 20. When the movable clamping plate 2 is displaced, it drives the guiding sliding sleeve 20 to slide on the guiding threaded column 18, making the displacement of the movable clamping plate 2 stable. The guiding threaded column 18 can also provide blocking protection for the plate assembly 3.

[0032] Specifically, two symmetrically arranged mounting plates 21 are fixedly connected to the upper side wall of the movable clamping plate 2. A roller 22 is rotatably connected between the two mounting plates 21 through a rotating shaft. The roller 22 is in rolling connection with the upper side wall of the upper end of the concave-shaped vertical frame 4, making the movement of the movable clamping plate 2 more stable.

[0033] Furthermore, base plates 23 are fixedly connected to both ends of the bottom of the fixed pressing plate 1 and one end of the bottom of the concave-shaped vertical frame 4, which are used for fixing to the surface of the ship deck.

[0034] In this embodiment, a sealing rubber sleeve 24 is fixedly connected to the inner wall of the fluid through-port 5 to improve the connection tightness, which is a prior art.

[0035] The working principle of the present utility model:

[0036] When it is necessary to adjust the displacement of the movable clamping plate 2, first, push the push block 14 to displace, driving the limiting rod 16 fixed to the slider 12 to displace. At this time, the compression spring 13 is squeezed and contracts to generate elastic force until the limiting rod 16 is separated from the limiting groove 17. At this time, the rotation of the circular rotating block 7 is no longer restricted, and the circular rotating block 7 can be rotated to drive the lead screw 6 to rotate. Since the lead screw 6 is threadedly connected to the nut block 8, at this time, the nut block 8 is forced to displace, and then drives the two connecting frames 9 to displace simultaneously, so as to realize the displacement adjustment of the movable clamping plate 2. The operation is simple and convenient. Compared with driving and adjusting by a cylinder, the manufacturing cost is lower and the subsequent maintenance is more convenient. At this time, the plate assembly 3 can be stretched and unfolded for cleaning. Then, after adjustment, release the push block 14. At this time, by the elastic force of the compression spring 13, the limiting rod 16 can be pushed to automatically insert into the limiting groove 17 to limit and lock the rotation of the circular rotating block 7, making the positioning of the movable clamping plate 2 more stable and preventing the displacement of the movable clamping plate 2 caused by vibration or other reasons during the navigation of the ship.

[0037] An embodiment of the utility model discloses an efficient plate heat exchanger for a ship ballast water system. By arranging a translation adjustment mechanism, when it is necessary to adjust the displacement of the movable clamping plate, only the round rotating block needs to be rotated to drive the screw rod to rotate. Since the screw rod is threadedly connected with the nut block, at this time, the nut block is forced to displace, and then drives the two connecting frames to displace simultaneously, so as to realize the displacement adjustment of the movable clamping plate. The operation is simple and convenient. Compared with driving adjustment by a cylinder, the manufacturing cost is lower and subsequent maintenance is more convenient.

[0038] Moreover, by arranging a limiting mechanism, when it is necessary to rotate the round rotating block, first push the push block to displace, driving the limiting rod fixed to the slider to displace. At this time, the compression spring is squeezed and contracts to generate an elastic force until the limiting rod is separated from the limiting groove. At this time, the rotation of the round rotating block is no longer restricted, and the round rotating block can be rotated to adjust the displacement of the movable clamping plate. After adjustment, release the push block. At this time, by the elastic force of the compression spring, the limiting rod can be pushed to automatically insert into the limiting groove to limit and lock the rotation of the round rotating block, making the positioning of the movable clamping plate more stable and preventing the displacement of the movable clamping plate due to vibration or other reasons during the navigation of the ship.
