The working principle of the invention is as follows:
When the heat exchange efficiency of the heat exchanger needs to be adjusted, firstly, a worker can pull the connecting pull rod 15, the connecting pull rod 15 moves to drive the adjusting inserting rod 11 to move together through the adjusting pull block 12 until the adjusting inserting rod 11 moves out of the adjusting jack, the adjusting sliding sleeve 6 is loosened, at the moment, the mounting moving plate 7 can move up and down, the mounting moving plate 7 can drive the adjusting baffle plate 4 to move up and down together through the adjusting screw rod 8 and the vertical screw barrel 9, the position of the adjusting baffle plate 4 is quickly adjusted, after the adjusting baffle plate 4 is quickly adjusted to a proper position, the worker can directly loosen the connecting pull rod 15, at the moment, the adjusting pull block 12 and the connecting pull rod 15 can be pulled to automatically reset under the elastic force of the return tension spring 13, and then the adjusting inserting rod 11 can be driven to be automatically reset to be inserted into the adjusting jack, the adjusting sliding sleeve 6 is always fixed, the staff can pull the unlocking pull block 20, the unlocking pull block 20 moves to drive the locking tooth block 19 together through the hexagonal slide bar 18 until the locking tooth block 19 moves to be separated from the locking gear 16, the locking gear 16 and the adjusting screw rod 8 are loosened, at the moment, the adjusting knob 10 can be rotated, the adjusting screw rod 8 can be driven to rotate by the rotation of the adjusting knob 10, the adjusting screw rod 8 can be driven to slowly move up and down through the vertical screw cylinder 9 under the common cooperation of the vertical guide rod 14, the position of the adjusting baffle 4 can be finely adjusted, the position of the adjusting baffle 4 can be rapidly and accurately adjusted, the heat exchange area between the cold medium in the cold fluid heat exchange tube 3 and the heat medium below can be correspondingly changed due to the change of the position of the adjusting baffle 4, and the aim of adjusting the heat exchange efficiency of the heat exchanger is achieved, therefore, the heat exchanger can meet different heat exchange requirements of different fluids, the application range is wide, after the adjusting partition plate 4 is accurately adjusted to a proper position, a worker can directly loosen the unlocking pull block 20, under the action of the elastic force of the reset spring 21, the reset baffle can be extruded and pushed to automatically reset, and then the hexagonal slide bar 18 can drive the locking tooth block 19 to automatically reset together to be meshed with the locking gear 16, the locking gear 16 and the adjusting screw 8 are always locked and can not rotate, the condition that the position of the adjusting partition plate 4 is changed due to the fact that the adjusting knob 10 is carelessly touched can be effectively reduced in the use process, and the heat exchanger is simple to operate, convenient and practical.
When the heat exchanger needs to be disassembled and maintained, a worker can rotate the control hand wheel 28, the control hand wheel 28 rotates to drive the bidirectional screw rod 26 to rotate, at the moment, under the joint cooperation of the horizontal guide rod 29 and the horizontal guide block 30, the bidirectional screw rod 26 rotates to drive the two horizontal inserting rods 27 to move in opposite directions or move in opposite directions until the two horizontal inserting rods 27 move in opposite directions to simultaneously move out of the two horizontal inserting holes, the two vertical supporting plates 24 can be simultaneously loosened, at the moment, the heat exchanger main body can be directly taken down for maintenance, after the maintenance is completed, the heat exchanger main body can be taken up to align the vertical supporting plates 24 to be inserted into the positioning grooves 31 for limiting and positioning, and then the worker can reversely rotate the control hand wheel 28 until the two horizontal inserting rods 27 are moved in opposite directions to be simultaneously inserted into the two horizontal inserting holes, the two vertical supporting plates 24 can be simultaneously fixed, and the installation operation can be completed.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present invention.
