Embodiment 1

[0030] Such as Figure 1-4 As shown, the wide-channel self-locking support heat exchange core of the present invention includes several plate pairs stacked in layers, and each plate pair includes two upper and lower plates 8 arranged opposite to each other. The upper surface of the plates 8 is along the Several rows of convex bumps 15 and concave bumps 16 are distributed in the direction of the same axis. The convex bumps 15 and concave bumps 16 are respectively obtained by pressing the plate 8 upwards and downwards. The convex bumps 15 and concave bumps 16 are distributed at intervals. There is a fixed distance between 16, the concave bulge 16 of the upper plate 8 is opposite to the concave bulge 16 of the lower plate 8 in the center of the plate pair, and the convex bulge 15 of the upper plate 8 in the plate pair is offset against the convex bulge 15 of the lower plate 8 A group of plates 8 are pressed upwards to form a short fold 14 that is consistent with the height of the...

Embodiment 2

[0039] Such as Figure 5-6 As shown, the wide-channel self-locking support slurry heat exchanger of the present invention includes the above-mentioned heat exchange core 1, and also includes the hot-side inlet pipe box 2, the hot-side outlet pipe box 6, the cold-side inlet pipe box 3, the cold-side Outlet pipe box 7, pressure plate 4, cold side inlet and outlet are left at both ends of the long flange 13 on one side, the cold side inlet is connected to the cold side inlet pipe box 3, the cold side outlet is connected to the cold side outlet pipe box 7; the hot side wide channel One end of 10 is connected to the hot-side inlet pipe box 2, and the other end is connected to the hot-side outlet pipe box 6; the pressure plate 4 stands on both sides of the hot-side wide channel 10, and the two sides are fixed by a tie rod and a nut across the heat exchange core 1.

[0040]The hot-side inlet pipe box 2, the hot-side outlet pipe box 6, the cold-side inlet pipe box 3, and the cold-side...

Abstract

The invention relates to a wide-channel self-locking support heat exchange core and a slurry heat exchanger, and belongs to the technical field of plate heat exchangers. The heat exchange core comprises a plurality of plate pairs which are stacked layer by layer, wherein each plate pair comprises an upper plate and a lower plate which are arranged in opposite directions; a plurality of rows of convex bulges and concave bulges are distributed on the upper surface of each plate at intervals, and a fixed interval is reserved between the concave bulges; a group of opposite sides of each plate arepressed upwards to form a short folded edge with the same height as the convex bulges, and the other group of opposite sides are pressed downwards to form a long folded edge; two adjacent plate pairsare symmetrical up and down, the long folded edge between the two adjacent plate pairs and an inlaid strip are welded to form a cold-side narrow channel; and two ends of the short folded edge in eachplate pair and the inlaid strip are welded to form a hot-side wide channel. The heat exchanger comprises the heat exchange core body, a hot side inlet pipe box, a hot side outlet pipe box, a cold sideinlet pipe box, a cold side outlet pipe box and a pressing plate. The wide-channel self-locking support heat exchange core ensures the internal supporting strength of a wide channel and solves the leakage and falling phenomena caused by welding spot tension cracking.

Description

technical field [0001] The invention relates to a wide-channel self-locking support heat exchange core body and a slurry heat exchanger, belonging to the technical field of plate heat exchangers. Background technique [0002] At present, plate heat exchangers have been widely used in petrochemical, electric power, metallurgy, medicine, food and other industries. Due to their advantages of high heat exchange efficiency, small heat exchange temperature difference, compact structure and small footprint, they have been widely used in various industries. industry recognition. However, in some special working conditions, such as liquids containing large-diameter solid particles and crystals, and mediums that are easy to solidify and have poor fluidity, the flow channels are often blocked during the heat exchange process and the heat exchange efficiency is reduced. At present, the wide channel plate type In order to meet the operating conditions of the heat exchanger, the channel ...
