Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a plate heat exchanger that is easy to disassemble and assemble. Background Technology

[0002] Plate heat exchangers are a type of high-efficiency heat exchanger consisting of a series of metal plates with a certain corrugated shape stacked together. Thin rectangular channels are formed between the various plates, and heat exchange occurs through the plates. They have the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life.

[0003] In the prior art, plate heat exchangers are usually composed of a fixed plate and a movable plate. The fixed plate is equipped with two sets of upper and lower limit rods. During installation, the plates are installed between the two sets of limit rods, and then the plates are clamped by the movable plate. When clamping begins, check from the side to see if the installation direction and installation surface of the plates are incorrect. If the installation is correct, the side will have a honeycomb pattern.

[0004] However, the plates may be installed incorrectly. In this case, almost all the plates have been installed on the limit rod, and the gap between adjacent plates is small, making it inconvenient to disassemble and replace some incorrect plates. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a plate heat exchanger that is easy to assemble and disassemble includes a main fixed plate 101. Two upper and lower limiting rods 102 are fixedly connected to one side of the main fixed plate 101, and a secondary fixed plate 103 is fixedly connected to the other end of the limiting rods 102. Several plates 2 are installed between the two limiting rods 102.

[0027] A clamping assembly is provided between the main fixing plate 101 and the secondary fixing plate 103. The clamping assembly includes a screw 301 threadedly connected to the secondary fixing plate 103. A knob 302 is fixedly connected to one end of the screw 301 away from the main fixing plate 101. A clamping plate 303 is rotatably connected to the other end of the screw 301. The clamping plate 303 slides along the limiting rod 102. By rotating the screw 301 through the knob 302, the screw 301 drives the clamping plate 303 to slide back and forth along the limiting rod 102.

[0028] A slide rod 4 is fixedly connected between the main fixing plate 101 and the secondary fixing plate 103. The clamping plate 303 slides along the slide rod 4. An auxiliary mechanism is provided on the slide rod 4. The auxiliary mechanism includes a moving block 501 that is slidably connected to the slide rod 4. A locking assembly is provided between the moving block 501 and the slide rod 4. The locking assembly includes a locking bolt 502 that is threadedly connected to the top wall of the moving block 501.

[0029] The bottom of the movable block 501 is connected to a telescopic rod 504 via a telescopic component. The telescopic component includes a fixed sleeve 503 fixedly connected to the bottom of the movable block 501. A square groove is provided on the inner wall of the fixed sleeve 503. A square slider is fixedly connected to the side wall of the telescopic rod 504. The slider is slidably connected in the groove. The bottom end of the telescopic rod 504 extends out of the fixed sleeve 503 and is rotatably connected to the first rotating ring 505 and the second rotating ring 506. The fixed sleeve 503 and the telescopic rod 504 are in frictional engagement so that the position of the telescopic rod 504 does not change after extension and retraction.

[0030] The outer wall of the telescopic rod 504 is rotatably connected to a first rotating ring 505 and a second rotating ring 506. A torsion spring for resetting is provided between the first rotating ring 505 and the second rotating ring 506. A fixing rod 507 is fixedly connected to both the first rotating ring 505 and the second rotating ring 506. The two sets of fixing rods 507 are arranged in an X-shape. A connecting rod 508 is fixedly connected to the bottom of each fixing rod 507. A support plate 509 is fixedly connected to the bottom of the connecting rod 508. The bottom end of the support plate 509 is a V-shape with the tip pointing downwards, which makes it easy to extend into the gap between two adjacent plates 2.

[0031] The auxiliary mechanism also includes two sets of power components arranged symmetrically in front and behind. The power components are used to drive the two left and right support plates 509 to move in a direction away from each other. The power components include extension plates 601 fixedly connected to the front and rear side walls of the moving block 501. A rotary motor 602 is fixedly connected to the bottom of the extension plate 601. A paddle 603 is fixedly connected to the output end of the rotary motor 602. The paddle 603 is located in the gap between the two sets of fixed rods 507. The edges of the paddle 603 are rounded to reduce the friction between the paddle 603 and the fixed rods 507.

[0032] Working principle: During installation, several plates 2 are placed between the upper and lower sets of limiting rods 102. After the plates 2 are installed, an inspection is performed. If some plates 2 are found to be installed incorrectly, the locking bolts 502 are loosened, the moving block 501 is moved to the appropriate position, and the telescopic rod 504 is pulled down so that the support plate 509 is located in the gap on both sides of the plate 2 to be removed. The rotary motor 602 is started, and the rotary motor 602 drives the lever 603 to rotate. The lever 603 opens the two sets of fixing rods 507, thereby driving the left and right sets of support plates 509 to move away from each other. Move the plate to be replaced to increase the gap between the two sides of the plate 2 to be removed, remove the plate 2 to be replaced, and reinstall it between the two sets of limit rods 102 in the correct manner. Then, rotate the motor 602 in reverse. The first rotating ring 505 and the second rotating ring 506 drive the fixing rod 507 to drive the connecting rod 508 and the support plate 509 to reset under the action of the torsion spring. Then, push the telescopic rod 504 upward to make the support plate 509 extend from between the plates 2. Then, turn the screw 301 by the knob 302 to move the clamping plate 303 toward the direction closer to the main fixing plate 101 to clamp the plate 2.
