Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger processing, in particular to a clamping device. Background Art

[0002] A heat exchanger, also known as a heat exchanger, is a device that transfers some of the heat from a hot fluid to a cold fluid. Heat exchangers play a vital role in chemical, petroleum, power, food, and many other industrial processes. In chemical production, they can serve as heaters, coolers, condensers, evaporators, and reboilers, among other applications. However, corrosion can occur within the heat exchanger's internal tubes during use, seriously impacting their performance and lifespan. To effectively control corrosion, an anti-corrosion coating can be applied to the surface of the heat exchanger tubes.

[0003] The clamping device in the existing technology mainly requires workers to manually take the inner tube of the heat exchanger for spraying the preservative, which cannot effectively ensure the stability of the inner tube of the heat exchanger during the spraying process. In addition, long-term contact with the preservative will also cause physical damage to the workers. Utility Model Content

A hinge 4 is movably connected to the top of the top plate 3, and the top of the water tank 2 is opened to avoid the inability to clean the inner wall of the water tank 2 after dirt appears, which affects the anti-corrosion effect of the preservative. An observation window 5 is provided on the front of the water tank 2, which is convenient for users to check the remaining preservative inside and replenish it in time. A first slide groove 6 is provided on the front of the bottom plate 1, a screw rod 7 is provided inside the first slide groove 6, and a driving motor 8 is provided on one side of the screw rod 7. The outer wall of the screw rod 7 is slidably connected to a first slider 9, and the outer wall of the first slider 9 is movably connected to a bracket 10. An annular tube 11 is movably connected to one side of the frame 10, and a nozzle 12 is provided on the inner wall of the annular tube 11. The moving position of the annular tube 11 is adjusted in conjunction with the driving motor 8 to perform all-round anti-corrosion spraying on the inner tube of the heat exchanger. A hose 13 is provided on the top of the annular tube 11, and a delivery pipe 14 is provided on one side of the hose 13. A second slide 15 is provided on the top of the base plate 1, and a first adjusting rod 16 is provided inside the second slide 15. A column 17 is movably connected to the top of the base plate 1, and a fixing ring 18 is fixedly connected to the top of the column 17. The outer wall of the fixing ring 18 is movably connected to the second adjusting rod 19, and an extrusion block 20 is provided on one side of the second adjusting rod 19. The outer wall of the first adjusting rod 16 is slidably connected to the second slider 21, which meets the needs of clamping and fixing the inner tubes of heat exchangers of different sizes and lengths, and is more convenient to use. A water pump 22 is provided inside the water tank 2.

[0018] Among them, there are two groups of columns 17 and fixing rings 18. The outer wall of each group of fixing rings 18 is provided with three groups of second adjusting rods 19. A buffer pad is provided on one side of the extrusion block 20, which can be freely adjusted according to the different models of the inner tubes of the heat exchanger, and different sizes can be clamped and fixed. At the same time, it can avoid excessive extrusion force to cause damage to the inner tubes of the heat exchanger.

[0019] Among them, the bracket 10 has an L-shaped appearance, and the distance between the bracket 10 and the base plate 1 is one centimeter. The number of the brackets 10 is two groups to avoid friction caused by being too close to the base plate 1 and affecting the movement effect.

[0022] The driving motor 8 , the lead screw 7 , and the first slider 9 form a moving device. There are two groups of moving devices, and the two groups of moving devices rotate synchronously.

[0023] Specifically, when in use, the staff opens the top plate 3, then pours the required preservative into the water tank 2, and then closes the top plate 3. Then the user rotates the first adjusting rod 16 and adjusts the position of the second slider 21 according to the length of the inner tube of the heat exchanger to be clamped. After the adjustment is completed, the inner tube of the heat exchanger is placed on the inner wall of the annular tube 11 and the fixing ring 18, and the second adjusting rod 19 is rotated to clamp and fix the inner tube of the heat exchanger to facilitate subsequent anti-corrosion spraying. Then the motor 8 is driven to control the screw rod 7 to rotate, so that the annular tube 11 moves back and forth along the first slide groove 6. While moving, the water pump 22 inside the water tank 2 injects the preservative inside the water tank 2 into the annular tube 11 through the hose 13 and sprays it out through the nozzle 12 to perform anti-corrosion treatment on the inner tube of the heat exchanger.
