Lightweight high-temperature-resistant plate heat exchanger

Abstract

This invention provides a lightweight, high-temperature resistant plate heat exchanger. The lightweight, high-temperature resistant plate heat exchanger includes: an installation assembly, which is equipped with a horizontal moving assembly and a sliding assembly. The horizontal moving assembly is connected to two sets of cover plates, and the sliding assembly is connected to heat exchange plates. A detachable assembly connects the heat exchange plates to the sliding assembly. The horizontal moving assembly controls the movement of the cover plates. In this lightweight, high-temperature resistant plate heat exchanger, rotating the limiting plate away from the entry end of the limiting groove facilitates the removal of the limiting block from the limiting groove and the replacement of new heat exchange plates. Releasing the limiting plate causes a torsion spring to automatically reset it. These devices improve the efficiency of heat exchange plate replacement. The output end of the motor drives a bidirectional threaded rod to rotate, causing the two sets of threaded blocks to bring the cover plates closer together, thus assembling the heat exchange plates.

[0024] The installation component 1 includes a workbench 11, the top of which has a rectangular groove 12, and the inner walls of the front and rear sides of the rectangular groove 12 have sliding grooves 13. The inner walls of the sliding grooves 13 are connected to the sliding component 6, and the inner walls of the rectangular groove 12 are connected to the horizontal moving component 2.

[0025] The horizontal moving component 2 drives the sliding component 6 to move closer to each other through two sets of cover plates 4.

Both ends of the bidirectional threaded rod 22 are threadedly connected to threaded blocks 23, and the tops of the two sets of threaded blocks 23 are fixedly connected to the cover plate 4.

[0027] The output end of the motor 21 drives the bidirectional threaded rod 22 to rotate, causing the two sets of threaded blocks 23 to move the cover plate 4 closer to each other and bring the heat exchange plates 5 together.
