Embodiment Construction

[0031] refer to figure 1 , figure 2 with image 3 , shows a plate heat exchanger 2 with gaskets. It comprises a first end plate in the form of a frame plate 4, a second end plate in the form of a pressure plate 6, and corrugated (not shown) heat transfer plates arranged in alignment between the parallel frame plate 4 and pressure plate 6 respectively. plate 10 ( image 3 ) group 8. The heat exchanger also comprises: an upper bearing rod 12 of stainless steel, having a rectangular cross-section; a lower guide rod 14 ("lower rod" in the claims), which will be described in more detail later; and a support column 16. The support columns 16 and frame panels 4 are arranged to be fixed to the ground 18 ( figure 2 ), and from there extend in parallel at a distance from each other, with the ground-supported pressure plates 6 being movably arranged therebetween. The load bar 12 is attached at a first end to the upper portion of the frame plate 4 and at a second end to the upper ...

Abstract

A plate heat exchanger (2) comprising first and second end plates (4, 6), a lower bar (14, 66) extending from the first end plate (4) towards the second end plate (6),and a pack (8) of heat transfer plates (10) arranged between the first and second end plates and extending above the lower bar, is provided. The plate heat exchanger is characterized in that the lower bar (14, 66) comprises a groove(40, 82) having a length axis (L) which extends parallel to a longitudinal direction (l) of the lower bar (14, 66), and a depth axis (D) extending perpendicular to the length axis. The plate heat exchanger further comprises a support foot (42). An upper portion (56) of the support foot (42) is arranged to be received in the groove (40, 82) and a lower portion (59) of the support foot (42) is arranged to extend from the lower bar (14, 66) and contact the ground (18) to keep the lower bar at a distance from the ground. The upper portion (56) of the support foot (42) is arranged to be slidable inthe groove (40, 82) along the length axis (L) to enable adjustment of a position of the support foot (42) along the lower bar (14, 66).

Description

technical field [0001] The invention relates to a plate heat exchanger, which comprises a first end plate and a second end plate, a lower bar extending from the first end plate toward the second end plate, and a bottom rod arranged between the first end plate and the second end plate. A set of heat transfer plates extending between the two end plates and above the lower rod. Background technique [0002] A plate heat exchanger PHE typically consists of two end plates between which a plurality of heat transfer plates are arranged in an aligned manner (ie in a stack or group). In one type of well-known PHE, the so-called gasketed plate heat exchanger, gaskets are arranged between heat transfer plates. The end plates and thus the heat transfer plates are pressed towards each other by some kind of fastening means whereby the gasket seals between the heat transfer plates. Parallel flow channels are formed between the heat transfer plates, one channel between each pair of adjace...
