Description

Technical Field

[0001] The invention relates to the technical field of heat exchanger assembly, and in particular to a three-dimensional installation structure and an installation method for a plate heat exchanger. Background Art

[0002] Plate heat exchanger is a kind of high-efficiency heat exchanger made of a series of metal sheets with certain corrugated shapes. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-steam heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, wide application and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of tubular heat exchanger, and the footprint is one-third of that of tubular heat exchanger, and the heat recovery rate can be as high as more than 90%.

[0003] During the installation of the plate heat exchanger, the head plate, middle plate, and tail plate need to be fastened together. During installation, multiple plates need to be directly compressed together. However, many customers who purchase plate heat exchangers do not have matching automated assembly lines. In order to allow customers to inspect the integrity of the heat exchanger parts by themselves, manufacturers of plate heat exchangers ship them in bulk, making it easier for customers to inspect the goods (parts) after receiving them.

[0004] Moreover, plate heat exchangers are prone to scale accumulation, and they need to be disassembled and maintained every time they are used for a period of time.

[0005] However, during the initial assembly and subsequent maintenance of the plate heat exchanger, it is necessary to align the heat exchange clamping plates more accurately so that the sealing rings between the clamping plates can be aligned and installed. The plate heat exchanger itself does not have good alignment components. There are only a few long fastening screws. The clamping plates are directly pushed tight manually, and then the multiple long fixing screws are tightened with nuts in turn. This can easily cause a slight "misalignment" of the sealing rings between the clamping plates. When the internal pressure and temperature of the heat exchange are high, long-term high-load operation can easily aggravate problems such as aging and leakage of the sealing rings.

[0006] However, purchasing automated assembly line equipment is expensive and is not economical for ordinary customers who only use plate heat exchangers.

[0007] In summary, how to effectively solve the problems of precise assembly of plate heat exchanger plates and the cost of assembly equipment has become a difficult problem. Summary of the invention

[0008] To solve the above problems, the present invention provides a three-dimensional installation structure and installation method for a plate heat exchanger, thereby achieving precise assembly between the plates of the plate heat exchanger.

Manually rotate the rotating member (802), the rotating member (802) pushes the linkage mounting member (9) away from the front end plate (1), the linkage mounting member (9) drives the guide tube (501) to move, and the tail plate (4) magnetically attracted at the end of the guide tube (501) pushes each splint plate (3) to squeeze and contact, and moves toward the front end plate (1); S9. After the preliminary assembly of the tail plate (4), each clamping plate (3), and the front plate (1) is completed, the front plate (1), the rear plate (2), the clamping plate (3), and the tail plate (4) are finally fastened and installed using a plurality of long screws on the ring side of the plate heat exchanger; S10. Disassemble the linkage mounting member (9), the displacement adjusting member (8), the sliding guide member (5) and the clamping base member (7) in sequence.
