Description

Technical Field

[0001] This utility model relates to the field of plate heat exchanger maintenance technology, and in particular to a plate heat exchanger disassembly device. Background Technology

[0002] A plate heat exchanger is a type of heat exchanger assembled from a series of corrugated metal plates. It features high heat exchange efficiency, low heat loss, a compact and lightweight structure, small footprint, and long service life. It mainly includes heat exchange plates, fixed clamps, movable clamps, clamping bolts, upper guide rods, and lower guide rods. During use, the heat exchange plates of a plate heat exchanger can become clogged and scaled, leading to a decrease in heat exchange efficiency. Therefore, it is necessary to periodically disassemble the heat exchanger to clean the clogged plates and scale.

[0003] Plate heat exchangers have high internal pressure, and the plates are pressed very tightly together to prevent leakage. During disassembly, the large expansion force between the plates makes it difficult to remove the fastening nuts. To facilitate the removal of the fastening nuts, this application proposes a plate heat exchanger disassembly device. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a plate heat exchanger disassembly device.

[0005] This utility model is achieved through the following technical solution: a plate heat exchanger disassembly device is provided, including a placement rack fixed to the ground for placing the plate heat exchanger. Two pads are provided on the top surface of the placement rack to support the fixed clamping plates of the plate heat exchanger. A pressure plate presses against the top surface of the movable clamping plates of the plate heat exchanger. The pressure plate is connected to the panel of the placement rack via a connecting frame. The connecting frame includes two vertical connecting plates, which are respectively vertically fixed to both ends of the pressure plate. Each vertical connecting plate penetrates the panel, and the lower ends of the two vertical connecting plates are connected by a pluggable horizontal plate. A driving mechanism for driving the pressure plate downward is provided between the horizontal plate and the panel. The downward movement of the pressure plate further presses the plates, thereby reducing the expansion force of the plates on the fastening nuts, thus facilitating the removal of the fastening nuts.

[0006] Preferably, the panel has through holes for each vertical connecting plate to pass through.

[0007] Preferably, mounting holes are provided at opposite positions of the two vertical connecting plates, and the horizontal plate passes through the two mounting holes sequentially.

[0008] Preferably, the driving mechanism is a jack, the base of which is placed on a horizontal plate. When the piston rod of the jack extends, it presses against the panel, and the connecting frame moves down under the reaction force, thereby moving the pressure plate down.

[0009] Preferably, the panel of the placement rack is supported by support legs, and ear plates are welded to the lower end of the support legs. The ear plates are fixed to the ground by bolts.

[0010] Preferably, the pressure plate, vertical connecting plate, and horizontal plate are all metal plates.

[0011] Preferably, the panel of the mounting rack is provided with positioning posts, which are used to insert into the pipe joints of the plate heat exchanger. The positioning posts can be inserted into the pipe joints to provide positioning.

[0012] The beneficial effects of this utility model are as follows: This utility model utilizes the combined use of a pressure plate, connecting frame, horizontal plate, and jack. Driven by the jack, the pressure plate moves downward, thereby reducing the expansion force exerted by the plate on the fastening nut, thus facilitating the removal of the fastening nut. The structure is simple and practical, and the effect is good. Attached Figure Description

[0014] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0015] like Figure 2-4As shown, this utility model includes a mounting frame fixed to the ground for placing a plate heat exchanger 1. Two pads 3 are provided on the top surface of the mounting frame to support a fixed clamping plate 11 for the plate heat exchanger 1. A pressure plate 8 presses against the top surface of a movable clamping plate 7 of the plate heat exchanger 1. The pressure plate 8 is connected to the panel 2 of the mounting frame via a connecting frame. The connecting frame includes two vertical connecting plates 9, which are vertically fixed to both ends of the pressure plate 8. Each vertical connecting plate 9 penetrates the panel 2, and the lower ends of the two vertical connecting plates 9 are connected by a pluggable horizontal plate 12. A driving mechanism for driving the pressure plate 8 downwards is provided between the horizontal plate 12 and the panel 2. The downward movement of the pressure plate 8 further presses the plates together, thereby reducing the tension force exerted by the plates on the fastening nuts, thus facilitating the removal of the fastening nuts.

[0016] In this embodiment, the panel 2 of the placement rack is supported by the support leg 5, and the ear plate 6 is welded to the lower end of the support leg 5. The ear plate 6 is fixed to the ground by bolts.

[0017] In this embodiment, the panel 2 is provided with through holes 14 for each vertical connecting plate 9 to pass through.

[0018] In this embodiment, mounting holes are provided at opposite positions of the two vertical connecting plates 9, and the horizontal plate 12 passes through the two mounting holes sequentially.

[0019] In this embodiment, the driving mechanism is a jack 13. The base of the jack 13 is placed on the horizontal plate 12. When the piston rod of the jack 13 extends, the piston rod presses against the panel 2. Under the reaction force, the connecting frame moves down, thereby moving the pressure plate 8 down.

[0020] In this embodiment, the pressure plate 8, the vertical connecting plate 9, and the horizontal plate 12 are all metal plates.

[0021] In this embodiment, a positioning post 4 is provided on the panel 2 of the placement rack. The positioning post 4 is used to insert into the pipe joint 10 of the plate heat exchanger 1. The positioning post 4 can be used for positioning when inserted into the pipe joint.

[0022] In practical use, the plate heat exchanger 1 to be disassembled is hoisted onto the placement frame. Two pads 3 support and fix the clamping plates, and the positioning pins 4 are inserted into the pipe joints. The pressure plate 8 is pressed onto the movable clamping plate 7, and the two vertical connecting plates 9 penetrate the panel 2. The horizontal plate 12 is then sequentially passed through the two mounting holes. Next, the jack 13 is placed on the horizontal plate 12, and the jack 13 is operated to lower the pressure plate 8. The lowering of the pressure plate 8 further tightens the plates, thereby reducing the tension on the fastening nuts and facilitating their removal.

[0023] This utility model utilizes the combined use of a pressure plate 8, a connecting frame, a horizontal plate 12, and a jack 13. Under the drive of the jack 13, the pressure plate 8 moves downward, thereby reducing the expansion force generated by the plate on the fastening nut, thus facilitating the removal of the fastening nut. The structure is simple and practical, and the effect is good.
