When the composite modified graphite heat exchanger needs to be moved, the clamp can be put on the graphite heat exchanger body, and then the two clamps are fixed on the graphite heat exchanger body by bolts and lock buckles after adjusting according to the diameter of the graphite heat exchanger body. The graphite heat exchanger body is moved easily and conveniently by pushing the moving carriage through the universal wheels, thereby solving the problem that the existing composite modified graphite heat exchanger does not have the function of being easy to move. When moving the graphite heat exchanger, a forklift or other tool is needed to assist, which is dangerous to operate and easy to cause damage and affects the service life.

The inner wall of the assembly frame 721 is slidably connected to a load-bearing slider 722, and the side surface of the load-bearing slider 722 is fixedly connected to a connecting column 723. The surface of the load-bearing slider 722 is fixedly connected to a limiting spring 724, and the limiting spring 724 is fixedly connected to the inner wall of the assembly frame 721.

The side surface of the L-shaped baffle 715 is provided with a socket, and the positioning pin 726 is plugged into the inner wall of the socket.

[0027] Specifically, the support bar 714 abuts against the surface of the T-shaped frame 711. There are two support bars 714, and the two support bars 714 are symmetrically arranged about the connecting column 713. The support bar 714 is located at one end of the connecting column 713 and is arc-shaped. Through the cooperation between the support bar 714 and the connecting column 713, the moving direction of the L-shaped baffle 715 can be guided to ensure that the L-shaped baffle 715 can move in a predetermined direction.

[0028] Specifically, the L-shaped baffle 715 abuts against the surface of the sleeve frame 4 , and the L-shaped baffle 715 is plugged into the inner wall of the assembly frame 721 .

[0029] In this embodiment, the side of the housing 4 can be shielded by the L-shaped baffle 715 , and the position of the T-shaped latch 716 can be limited in a restricted state.

[0030] Specifically, the T-shaped pin 716 is plugged into the inner wall of the sleeve 4, and the T-shape is removed to abut against the side surface of the support plate 3. By limiting the T-shaped pin 716 to the inner wall of the sleeve 4, the position of the support plate 3 inside the sleeve 4 can be limited.

[0036] Working principle: When the support plate 3 in the sleeve frame 4 needs to be disassembled, pinch the anti-slip pull block 725 and pull it outward. The anti-slip pull block 725 cooperates with the connecting column 723 to pull the load-bearing slider 722. The load-bearing slider 722 squeezes the limit spring 724. The limit spring 724 is squeezed and deformed by you. At the same time, the anti-slip pull block 725 is forced to pull the positioning pin 726 out of the socket. When the positioning pin 726 is completely out of the socket, pull the L-shaped baffle 715. Under the guidance of the support bar 714, the connecting column 713 and the T-shaped frame 711, the L-shaped baffle 715 pulls the T-shaped plug Pin 716, the T-shaped latch 716 is forced to separate from the sleeve 4. When the connecting column 713 moves to the maximum spacing, the L-shaped baffle 715 is rotated, and the L-shaped baffle 715 drives the T-shaped latch 716 to leave the socket part of the sleeve 4. Then the support plate 3 can be removed from the sleeve 4. By setting the auxiliary component 7 and the limiting unit 72, the structural strength of the equipment connection part is improved, thereby reducing the problem that the equipment connection part is only restricted by the latch, the structural strength is low and the stability is poor, and the structural strength and firmness of the equipment connection part are further improved.
