Description

TECHNICAL FIELD

[0001] The utility model relates to heat exchanger dismounting technical field, concretely to a quick dismounting device of plate heat exchanger. BACKGROUND

[0002] Plate heat exchanger is a kind of equipment that carries out heat exchange by parallel arrangement metal plate. Its working principle is to utilize the heat transfer when hot fluid flows between plates. The main components of plate heat exchanger include heat exchange plate, frame, sealing gasket and support structure. Unlike traditional shell-and-tube heat exchanger, the flow path of fluid between plates of plate heat exchanger can be designed more complex, thereby improving heat exchange efficiency.

[0003] Plate heat exchanger needs to be disassembled and cleaned after running for a certain time to clean the scale, welding slag and impurities in plate heat exchanger. Because the medium temperature in plate heat exchanger is high, sealing gasket will appear aging phenomenon and lose elasticity. After a long time, plate heat exchanger will appear leakage problem. How to quickly disassemble and reassemble heat exchanger components directly relates to work efficiency. In the process of disassembling and reassembling existing heat exchanger, most of them still use manpower and large wrench, which is labor-intensive and low in efficiency.

[0004] To solve the above problems, a quick dismounting device of plate heat exchanger is proposed to solve the above problems. CONTENT OF UTILITY MODEL

[0017] The technical scheme in the embodiment of the application is to solve the problems in the foregoing background art, and the general idea is as follows:

[0018] Embodiment: refer to Figure 1 - Figure 3 As shown in the drawing, the quick dismounting device of the plate heat exchanger of the embodiment comprises a jack 1, and the upper and lower ends of the jack 1 are respectively provided with a bottom beam 2 and a top beam 3; the jack 1 is fixedly installed at the upper end of the middle part of the bottom beam 2, the bottom beam 2 plays a role of stable support for the installation of the jack 1, and the top beam 3 is located in the direction of the top of the jack 1; the top beam 3 is parallel to the bottom beam 2, and the top beam 3 and the bottom beam 2 are connected through two groups of screw rods 4.

[0019] In some examples, the upper end of the screw rod 4 is provided with two groups of upper clamping nuts 5, and the two groups of upper clamping nuts 5 are respectively located at the two ends of the top beam 3; the two groups of upper clamping nuts 5 are used for clamping and locking the top beam 3, and the installation height of the top beam 3 can be adjusted by adjusting the upper clamping nuts 5.

[0020] In some examples, the lower end of the screw rod 4 is provided with two groups of lower clamping nuts 6, and the two groups of lower clamping nuts 6 are respectively located at the two ends of the bottom beam 2; the two groups of lower clamping nuts 6 are used for clamping and locking the bottom beam 2, and the installation height of the bottom beam 2 can be adjusted by adjusting the lower clamping nuts 6.

[0021] In some examples, the clamping surfaces of the upper clamping nuts 5 and the lower clamping nuts 6 are provided with clamping pads 7, which increase the clamping effect.

[0022] The working principle of the utility model is:

[0023] When the heat exchange plates of the plate heat exchanger need to be disassembled, first adjust the two groups of upper clamping nuts 5 on the top beam 3 to ensure that the distance between the jack 1 and the top beam 3 satisfies the condition of being sleeved on the plate heat exchanger, the piston head of the jack 1 needs to be pressed on the movable plate of the plate heat exchanger, and the top beam 3 abuts against the fixed plate of the plate heat exchanger, as shown in the reference Figure 3 .

[0024] Then fine-tune the upper clamping nuts 5 to ensure that the top beam 3 and the bottom beam 2 are parallel, and then press the operating handle of the jack 1 to ensure that there is a certain pressure between the piston head of the jack 1 and the movable plate of the plate heat exchanger, so that the movable plate can be supported and lifted forward, and the fastening nuts of the plate heat exchanger can be loosened without being pressed by the movable plate, so that the staff can quickly loosen the fastening nuts of the plate heat exchanger, and ensure that all the fastening nuts are on a horizontal plane and the horizontal displacement is basically equal to the plunger extension length of the jack 1, then operate the jack 1 to reset and retract the plunger. Repeat the above operation until the heat exchange plates of the plate heat exchanger can be easily taken out.

[0025] When the heat exchange plates of the plate heat exchanger need to be reassembled, the operation process is just the opposite of disassembling the heat exchange plates of the plate heat exchanger, and the fastening nuts of the plate heat exchanger are tightened to ensure that the thickness of the plate heat exchanger is the same as that before disassembly.

Those skilled in the art should understand that the utility model is not limited to the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the utility model, and various changes and improvements can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the claimed utility model.
