[0002] Plate heat exchanger unit is a type of heat exchanger unit, which is characterized by the use of plate heat exchanger. Steam or high-temperature water is sent into the plate heat exchanger unit according to the flow rate required by the heating system under the control of the temperature control valve. The heat exchanger heats the heating return water of the heat user by indirect heat exchange; the heated water first flows through the stainless steel core separator, and then enters the heat exchanger through the circulation pump to be heated for use by the user, and the cycle repeats.

Blocks 402 are movably sleeved on the left and right sides of the limit frame 401. There are two blocks 402. Blocks 403 are fixedly installed on the opposite backs of the two blocks 402. The other ends of the blocks 403 penetrate the limit frame 401 and the bottom plate 2 and extend to the inside of the bottom plate 2. Connecting rods 404 are hinged on the bottom ends of the two blocks 402. There are two connecting rods 404 and they are symmetrical with each other about the center of the limit frame 401.

The connecting rods 404 will move the blocks 403.

[0037] When the two connecting rods 404 rotate, since the connecting rods 404 and the blocks 402 are hinged, as the connecting rods 404 rotate, the connecting rods 404 will generate a pulling force on the blocks 402, pulling the two blocks 402 to move toward each other along the inner surface of the limit frame 401 and compressing the spring 405, so that the block 403 fixedly connected to the block 402 moves together, so that the block 403 and the bottom plate 2 are separated, thereby releasing the block 403 from fixing the plate heat exchanger 3, thereby facilitating the operator to disassemble the plate heat exchanger 3, and further facilitating the operator to maintain the plate heat exchanger 3.

[0049] When the second water pump 17 is started, the water in the water storage tank 21 will enter the water inlet pipe 15 through the regulating valve 20 , the right-angle water pipe 19 and the connecting water pipe 18 .

[0050] Among them, fixed boxes 22 are fixedly installed on the front and rear sides of the left and right ends of the base 1, and the number of fixed boxes 22 is four.

[0051] The existence of the rollers 24 will facilitate the movement of the plate heat exchanger unit.

[0052] Among them, the outer surface of the long rod 23 is provided with a groove 25, and the inside of the groove 25 is movably sleeved with a clamping rod 26. The top end of the clamping rod 26 passes through the fixed box 22 and extends to the inside of the fixed box 22 and is fixedly installed with a movable block 27. The movable block 27 is movably sleeved in the inside of the fixed box 22. The top end of the movable block 27 is hinged with a connecting rod 28, and the other end of the connecting rod 28 is hinged with a rectangular block 29. The rectangular block 29 is movably sleeved on the inner surface of the fixed box 22. The internal thread of the rectangular block 29 is sleeved with a threaded rod 30. The threaded rod 30 is movably sleeved on the top of the inside of the fixed box 22, and the rectangular block 29 will cause the clamping rod 26 to move.

[0054] The working principle and use process of this utility model:

[0055] First, the operator rotates the threaded rod 30 so that the rectangular block 29 threadedly connected to the threaded rod 30 moves to the left with the top of the connecting rod 28, so that the bottom end of the connecting rod 28 generates a pulling force on the top of the movable block 27, pulling the movable block 27 and the clamping rod 26 to move upward along the inner surface of the fixed box 22, so that the clamping rod 26 and the groove 25 are separated, and the lock of the clamping rod 26 on the long rod 23 is released. Then the operator rotates the other three threaded rods 30 in turn, and then the base 1 can be pushed so that the base 1 moves under the action of the roller 24, thereby moving to the specified position. The mutual cooperation of various mechanisms makes the position adjustment of the plate heat exchanger unit more convenient. Finally, the operator opens the primary water supply valve 6, the primary return valve 9, the secondary water supply valve 11, the first water pump 13, the second water pump 17 and the regulating valve 20 to start the plate heat exchanger unit.

[0056] When the plate heat exchanger 3 needs to be inspected and maintained, the operator stops the operation of the plate heat exchanger unit and then turns the handle 502, so that the round rod 501 drives the disc 503 to rotate. At this time, the connecting rod 404 will rotate together with the disc 503, so that the other ends of the two connecting rods 404 respectively generate a pulling force on the two blocks 402, pulling the two blocks 402 to move towards each other with the two clamping blocks 403 and compressing the spring 405, so that the clamping block 403 and the bottom plate 2 are separated, and then the operator can remove the plate heat exchanger 3, thereby realizing the rapid disassembly of the plate heat exchanger 3, which is convenient for the operator to inspect and maintain the plate heat exchanger 3.
