[0001] The utility model relates to the technical field of heat exchangers, in particular to a plate heat exchanger which is convenient for descaling. Background Art

[0002] The plate heat exchanger is a high-efficiency heat exchanger made of multiple stacked corrugated metal sheets. Thin rectangular channels are formed between various corrugated sheets, and heat is exchanged through the plates. The heat exchange flow rate can be adjusted by increasing or decreasing the corrugated sheets according to the needs of specific scenarios. It has a wide range of applications in the market. Because the corrugated sheets are closely spaced, scale will inevitably form during use to block the corrugated flow channel, which is not conducive to the use of the plate heat exchanger. The current way to remove scale is usually for personnel to disassemble and separate the corrugated sheets, and then clean the scale formed in them. This process is inefficient and labor-intensive, making it inconvenient to remove scale from the plate heat exchanger. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a plate heat exchanger which is easy to remove scale. The scale on the corrugated sheet is removed by the energy generated during the vibration process. At the same time, a gap is generated between two adjacent corrugated sheets during the vibration process, which is convenient for scale to escape from between the two adjacent corrugated sheets. An elastic member is provided to assist in separating the corrugated sheets, which assists in generating a gap between the two adjacent corrugated sheets, which is convenient for external cleaning liquid to contact the corrugated sheets to play an effective cleaning role, and can effectively solve the problems in the background technology.

The vibration energy acts on the corrugated sheets 3 through the upper guide rod 6, so that the scale adhered to the side of the corrugated sheets 3 is forced to fall off.

The energy of the vibration acts on the corrugated thin plates 3 through the upper guide rod 6, so that the scale adhered to the side of the corrugated thin plates 3 is forced to fall off, and at the same time, the stacked corrugated thin plates 3 are dispersed under the action of vibration to form gaps, and the scale that falls off falls off from the gap between two adjacent corrugated thin plates 3, so as to facilitate the removal of scale in the plate heat exchanger;

[0027] After the adjusting nut 42 is rotated to loosen the clamping of the front clamping plate 1 and the rear clamping plate 2 on the stacked corrugated sheets 3, the elastic member 13 causes two adjacent corrugated sheets 3 to spring open to create a gap, thereby facilitating the separation of scale from the plate heat exchanger.
