Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a novel spiral plate heat exchanger. Background Art

[0002] The spiral plate heat exchanger is a high-efficiency heat exchange device that achieves efficient heat exchange through its unique spiral structure. It is composed of two parallel metal plates rolled into two spiral channels, and heat exchange between cold and hot fluids is carried out through the wall of the spiral plate.

[0003] After searching the publication number CN217442346U, a fixed-distance column type spiral plate heat exchanger is found, including a base, and support columns are fixedly provided at the four corners of the top of the base, wherein the tops of the two support columns are respectively rotatably arranged at the two ends of the first support ring through two rotating shafts, and the first support ring is fixedly arranged on one side of the heat exchanger body. The utility model provides a fixed-distance column type spiral plate heat exchanger, which drives the rotation of the heat exchanger body through the coordinated use of an electric telescopic rod, a pull plate, a slider, a connecting rod, a support rod and a sleeve, so that the heat exchanger body is rotated from a horizontal direction to a vertical direction, thereby facilitating the pouring out of the residue in the heat exchanger body, facilitating the cleaning of the heat exchanger body, and improving the cleaning efficiency of the heat exchanger body. Through the use of a fixed plate and a fixed rod, the contact area between the fixed distance column and the first heat exchange plate and the second heat exchange plate is increased, which facilitates the fixed support of the first heat exchange plate and the second heat exchange plate, and improves the supporting effect of the fixed distance column.

[0004] However, when the above device is in use, the heat exchanger can only pour out the larger particles of residue in the heat exchanger by rotating it from the horizontal direction to the vertical direction, while some smaller particles of residue will still adhere to the inner surface of the heat exchanger, resulting in incomplete cleaning. Therefore, it is necessary to provide a new type of spiral plate heat exchanger that can scrape and clean particle residues of different sizes to improve the completeness of the cleaning.
