Description

Technical Field

[0001] This utility model relates to the field of plate heat exchanger maintenance technology, specifically a plate heat exchanger cleaning device. Background Technology

[0002] Plate heat exchanger plates require regular cleaning to ensure heat exchange efficiency. There are two cleaning methods: chemical circulation cleaning and disassembly cleaning. Chemical circulation cleaning uses a circulating cleaning cart to pump chemical cleaning equipment into the plate radiator for rinsing, resulting in high disassembly efficiency. Disassembly cleaning, however, cleans the heat exchanger plates more thoroughly, but the overall disassembly and reassembly process is more time-consuming. Currently, some plate radiator disassembly procedures require manual immersion of the disassembled heat exchanger plates in a cleaning tank to loosen attached debris. The plates are then placed in a cleaning tank, where manual hand-held flushing is performed. This manual rinsing is time-consuming, labor-intensive, and inefficient, making it inconvenient to use.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Please see Figure 1-5 In this embodiment of the utility model, the plate heat exchanger cleaning device includes a positioning frame 10 and a limiting frame 111. The positioning frame 11 is slidably connected inside the limiting frame 111. Multiple positioning rods 12 are provided and slidably connected inside the positioning frame 111. The liquid storage tank 14 is fixedly connected between the positioning frame 10 and the positioning frame 11. The control seat 13 is slidably connected outside the positioning frame 10. Multiple flushing seats 133 are provided and slidably connected to the top of the control seat 13. The auxiliary module 15 is provided outside the liquid storage tank 14. The auxiliary module 15 can provide auxiliary limiting for the heat dissipation plate body 20.

[0032] Specifically, a rinsing seat 133 is slidably connected to the top of the control seat 13. Multiple heat sink bodies 20 are stably limited by the positioning rod 12. The hydraulic rod 101 is activated to drive the positioning rod 12 to move down and place multiple heat sink bodies 20 into the positioning frame 10 for immersion. The hydraulic rod 137 is activated to drive the two rinsing seats 133 to move up and down to rinse the heat sink bodies 20 one by one. There is no need for manual hand-held spray nozzle rinsing, which makes the cleaning efficiency of the heat sink bodies 20 higher, the operation simpler, saves manpower, and is convenient to use. Example 1

[0033] like Figure 1-3As shown, in this embodiment, a hydraulic rod 112 is fixedly connected to the top of the limiting frame 111, and the output end of the hydraulic rod 112 is fixedly connected to the positioning frame 111. A limiting seat 131 is fixedly connected to one side of the liquid storage tank 14. A control seat 13 is slidably connected to the inside of the limiting seat 131. A U-shaped plate 134 is slidably connected to the top of the control seat 13. A fixing pipe 132 is fixedly connected to the top of the U-shaped plate 134. Two flushing seats 133 are fixedly connected to the fixing pipe 132. A rubber hose 135 is fixedly connected to the outer wall of the fixing pipe 132. Hydraulic rods 136 are fixedly connected to both sides of the control seat 13. The output end of the hydraulic rod 136 is fixedly connected to the U-shaped plate 134. Multiple hydraulic rods 137 are fixedly connected to one side of the limiting seat 131. The output end of the hydraulic rods 137 is fixedly connected to the control seat 13.

[0034] In this embodiment, the activation of hydraulic rod 2 112 can drive the positioning frame 2 11 and the positioning rod 12 to move laterally as a whole, so that the positioning rod 12 protrudes from the inside of the support plate 102, making it convenient to load the heat sink body 20 onto the positioning rod 12. The limiting seat 131 slides and limits the control seat 13 in the vertical direction. The activation of hydraulic rod 4 137 can drive the flushing seat 133 to move up and down to flush the heat sink body 20. The rubber hose 135 is connected to the water supply source and can supply water to the fixed pipe 132 and the flushing seat 133. The activation of hydraulic rod 3 136 can drive the C-shaped plate 134 and the two flushing seats 133 to move laterally, thereby preventing obstruction of the movement of the heat sink body 20 on the positioning rod 12.

[0035] like Figure 2-4 As shown, in this embodiment, two guide plates 141 are symmetrically fixed to the inner bottom surface of the liquid storage tank 14, and a control pipe 142 is fixedly connected to the outer wall of the liquid storage tank 14. A support plate 102 is slidably connected to one side of the positioning frame 10, and the positioning rod 12 can be movably engaged with the support plate 102. Multiple hydraulic rods 101 are fixedly connected to the opposite sides of the positioning frame 10 and the positioning frame 11. The positioning rod 12 and the support plate 102 are both fixedly connected to the output end of the adjacent hydraulic rod 101.

[0036] In practice, the guide plate 141 can guide the cleaning fluid out, reducing internal residue and facilitating cleaning of the inside of the liquid storage tank 14. After the positioning rod 12 carries a number of heat sink bodies 20, one end of the positioning rod 12 is inserted into the support plate 102 for auxiliary support. Activating multiple hydraulic rods 101 can drive the positioning rod 12 to move the heat sink body 20 downwards in a stable manner, immersing the heat sink body 20 into the liquid storage tank 14. The cleaning fluid inside the liquid storage tank 14 is used to soak the heat sink body 20, loosening any impurities that adhere to it, making it easier to rinse the heat sink body 20 later. Example 2

[0037] Based on Embodiment 1, in order to stably limit the position of the heat sink body 20 during cleaning.

[0038] like Figure 1-5 As shown, in this embodiment, the auxiliary module 15 includes a mounting frame 151, which is fixedly connected to the outer wall of the positioning frame 10. Multiple limiting rods 154 are provided and are slidably connected to the outer wall of the mounting frame 151. A T-shaped frame 153 is fixedly connected to two limiting rods 154. A positioning groove 1531 is provided at the bottom of the T-shaped frame 153. A hydraulic rod 155 is fixedly connected to the outer wall of the mounting frame 151. The output end of the mounting frame 151 is fixedly connected to the T-shaped frame 153. Two auxiliary rods 152 are fixedly connected to the inner wall of the mounting frame 151.

[0039] In practice, the mounting bracket 151 limits the two limiting rods 154, thereby limiting the vertical sliding of the T-shaped frame 153. Activating the hydraulic rod 155 drives the T-shaped frame 153 to move up and down. After the heat sink body 20 is manually transferred between the two rinsing seats 133, the hydraulic rod 155 is activated to drive the T-shaped frame 153 downwards. The positioning groove 1531 engages with the top of the heat sink body 20 for auxiliary limiting, making the heat sink body 20 more stable during rinsing. With the two auxiliary rods 152, after the hydraulic rod 2 112 drives the positioning frame 2 11 and the positioning rod 12 to move backward as a whole, the two auxiliary rods 152 can temporarily support the positioning rod 12. The heat sink body 20 is loaded from the end of the positioning rod 12 that is exposed, without causing obstruction. After the positioning rod 12 moves into the support plate 102, the force on the positioning rod 12 can also be distributed, making the positioning rod 12 more stable during the loading and unloading of the heat sink body 20.
