[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Plate heat exchangers are made of stacked corrugated metal sheets, with thin rectangular channels formed between various plates, and heat exchange is carried out through wide channel plate heat exchangers. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-gas heat exchange, with high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life.

[0003] When a traditional plate heat exchanger is in use, when the heat exchange plates inside the plate heat exchanger need to be replaced or maintained, the clamping bolts on the outer wall of the movable clamping plate need to be removed, but during the disassembly process, the nuts on the outer wall of the clamping bolts need to be removed. Due to the long length of the clamping bolts, this process is time-consuming and labor-intensive, and after the nuts are removed, the movable clamping plate needs to be manually pulled open, which is quite troublesome. Summary of the invention

[0007] As a preferred technical solution of the utility model: the outer wall diameter of the limiting rod matches the inner wall diameter of the limiting hole, and the outer wall of the driving motor is directly connected to the outer wall of the movable pressing plate.

[0008] As a preferred technical solution of the utility model: there are four driving gears, and the four driving gears are respectively installed on the outer wall of the movable pressing plate.

[0009] As a preferred technical solution of the utility model: the support shaft is installed at a position slightly above the center of the cam, and a rubber anti-slip sleeve is installed on the outer wall of the operating rod.

[0010] As a preferred technical solution of the utility model: an anti-skid ring is installed on the outer wall of the cam, and the anti-skid ring is made of vulcanized rubber.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The high-efficiency detachable wide-channel plate heat exchanger has a support plate arranged on the outer wall of the movable clamping plate and a cam arranged on the outer wall of the support shaft. Since the position of the support shaft does not coincide with the center position of the cam, when the cam is rotated, the outer wall of the cam can be separated from the outer wall of the limit rod or pressed against the outer wall of the limit rod, thereby fixing and releasing the movable clamping plate, avoiding the need to rotate the adjusting nut in traditional equipment, and being more convenient.

[0022] By installing a driving motor 9 and a driving gear 10 on the outer wall of the movable clamping plate 6, the driving gear 10 is driven by the driving motor 9, so that the outer wall of the driving gear 10 moves back and forth along the outer wall of the upper guide rod 2, thereby driving the movable clamping plate 6 under the action of the driving motor 9 and the driving gear 10, so that the movable clamping plate 6 can move back and forth along the outer wall of the upper guide rod 2.

[0023] In a preferred embodiment, the power output shaft of the driving motor 9 is connected to the outer wall of the driving gear 10 , and the outer wall of the driving gear 10 and the outer wall of the gear plate 4 are meshed with each other.

[0024] By setting the fixed plate 8 and the driving motor 9 on the outer wall of the movable clamping plate 6, and the driving motor 9 on the outer wall of the fixed plate 8, when the driving motor 9 rotates, it can drive the rotation of the driving motor 9, so that the outer wall of the driving gear 10 can move back and forth along the outer wall of the tooth plate 4 when it is meshed with the outer wall of the tooth plate 4, thereby realizing the adjustment of the position of the movable clamping plate 6.

[0025] In a preferred embodiment, the outer wall diameter of the limiting rod 7 matches the inner wall diameter of the limiting hole 11 , and the outer wall of the driving motor 9 is directly connected to the outer wall of the movable pressing plate 6 .

[0026] By setting a limit rod 7 on the outer wall of the fixed clamping plate 3, the outer wall of the movable clamping plate 6 can move forward and backward along the outer wall of the limit rod 7, thereby adjusting the position of the heat conducting plate 5 on the outer wall of the limit rod 7, so that two adjacent heat conducting plates 5 can be directly adjusted.

[0027] In a preferred embodiment, there are four driving gears 10 , and the four driving gears 10 are respectively mounted on the outer wall of the movable pressing plate 6 .

[0028] By installing four driving gears 10 on the outer wall of the movable clamping plate 6, the movable clamping plate 6 can be driven under the action of the four driving gears 10, so that the movable clamping plate 6 can move back and forth along the outer wall of the upper guide rod 2 more smoothly, and the heat conducting plate 5 on the outer wall of the limit rod 7 can be better disassembled.

[0029] In a preferred embodiment, the support shaft 13 is installed at a position above the center of the cam 14 , and a rubber anti-slip sleeve is installed on the outer wall of the operating rod 15 .

[0030] By placing the center of the cam 14 slightly below the outer wall of the support shaft 13, when the operating lever 15 is rotated, the cam 14 can rotate along the outer wall of the support shaft 13, and during the rotation of the cam 14, the outer wall of the cam 14 changes from a state of contacting the outer wall of the limit rod 7 to a state of not contacting the outer wall of the limit rod 7, thereby achieving locking and unlocking of the movable clamping plate 6.

[0031] In a preferred embodiment: an anti-skid ring is installed on the outer wall of the cam 14, and the anti-skid ring is made of vulcanized rubber.

[0032] By installing a rubber anti-skid ring on the outer wall of the cam 14, the outer wall of the cam 14 and the outer wall of the limit rod 7 can have greater friction under the action of the rubber anti-skid ring, so that the movable clamping plate 6 can be better fixed under the action of the cam 14.

[0033] Working principle: When the above-mentioned equipment is in use, when it is necessary to disassemble the equipment, it is only necessary to pull the operating lever 15, and the cam 14 is rotated under the action of the operating lever 15, so that the outer wall of the cam 14 is disengaged from the outer wall of the limit rod 7 during the rotation along the outer wall of the support shaft 13. At this time, the movable clamping plate 6 can be unlocked, and then the driving motor 9 is started. At this time, the driving motor 9 drives the driving gear 10 to rotate, and because the outer wall of the driving gear 10 is meshed with the outer wall of the tooth plate 4, the driving gear 10 can move back and forth along the outer wall of the tooth plate 4 during the rotation. At this time, under the action of multiple driving gears 10, the outer wall of the movable clamping plate 6 can be moved back and forth along the outer wall of the upper guide rod 2. When the upper guide rod 2 is moved away, the heat conduction plate 5 can be disassembled and maintained, which is very convenient.
